Description

  The present invention relates to a card connector. In particular, the present invention relates to a card connector with an ejection mechanism that facilitates card ejection.

  A so-called push-push type card connector with an eject mechanism is locked when the card is inserted (pushed) into the connector. When the card is pushed, the lock is released and the card is ejected from the connector. In the push-push type card connector, the card is easily ejected by an internal ejection mechanism by pressing the card.

  As the push-push type ejection mechanism described above, there is known an ejection mechanism including a slider that forms a heart-shaped cam groove and a guide rod that is guided by the heart-shaped cam groove (see, for example, Patent Document 1). ).

  In the connector provided with the eject mechanism described above, one end of the guide rod is moved in the heart-shaped cam groove by the pressing operation of the card, thereby defining the locking position and the discharging position of the card. However, the connector according to Patent Document 1 has a problem that the outer shape of the connector is increased because the wide slider is provided inside the housing.

  In order to eliminate the above-described problems, a small card connector has been disclosed by reducing the size of the card locking and discharging mechanism (see, for example, Patent Document 2).

  FIG. 16 is a partially enlarged perspective view of a housing provided in the card connector according to Patent Document 2. FIG. FIG. 16 of the present application corresponds to FIG. FIG. 17 is a plan view of a tray provided in the card connector according to Patent Document 2. FIG. FIG. 17 of the present application corresponds to FIG. 4 of Patent Document 2.

  18 is a view of a rotating cam member provided in the card connector according to Patent Document 2, FIG. 18 (A) is a right side view of the rotating cam member, and FIG. 18 (B) is a front view of the rotating cam member. FIG. 18C is a left side view of the rotating cam member. FIG. 18 of the present application corresponds to FIG. 13 of Patent Document 2.

  Referring to FIGS. 16 to 18, the card connector according to Patent Document 2 includes a plate-shaped housing 91 and a tray 92. The housing 91 has a plurality of contacts (not shown) arranged in the recess 910. The tray 92 is slidable with respect to the recess 910 and can receive a card (not shown).

  16 to 18, the tray 92 is engaged with the housing 91 so as to be maintained in the rear position when the card 92 is received in the front position and moved backward. Then, when the tray 92 is pressed again to the rear side, the engagement is released and the tray 92 returns to the front position again.

  Referring to FIG. 17, the tray 92 includes a protrusion 920 that protrudes from one side of the main body, and a column part 921 that extends rearward from the protrusion 920. A plurality of ratchet-shaped teeth 923 are formed radially at the rear end of the column portion 921.

  On the other hand, referring to FIG. 16, the housing 91 has a first cavity 911 and a second cavity 912 that extend in the sliding direction x of the tray 92 (see FIG. 17) and communicate with each other.

  Referring to FIGS. 16 and 18, the card connector according to Patent Document 2 includes a rotating cam member 93 that can slide and rotate inside the second cavity 912. The rotating cam member 93 is moved forward by being biased by a compression coil spring (not shown). Further, in the first cavity 911, the rotation cam member 93 is restricted in rotation, and only forward and backward movement is allowed.

  Referring to FIGS. 17 and 18, the rotating cam member 93 has a plurality of ratchet-shaped teeth 931 that mesh with the teeth 923 of the column portion 921 at one end. In addition, three protrusions 932 extending in the longitudinal direction of the main body 930 are provided at equal intervals on the outer periphery of the main body 930 of the rotating cam member 93.

  Referring to FIGS. 16 and 18, the outer surfaces of the three protrusions 932 are formed in an arc shape and can rotate inside the second cavity 912. On the other hand, the first cavity 911 has a substantially circular cross section, and radially forms grooves at equal intervals in three directions. These grooves extend along the longitudinal direction of the first cavity 911, one of which is a groove 911c whose bottom surface is open, and the other two are grooves 911a and 911b whose bottom surface is closed. The protrusion 932 can be guided and moved by the grooves 911a, 911b, and 911c.

  Since the card connector according to Patent Document 2 is configured as described above, when the tray 92 is moved rearward by pressing the card, the rotating cam member 93 is moved by being pressed by the column portion 921.

  When the rotating cam member 93 moves from the first cavity 911 to the second cavity 912, the rotating cam member 93 rotates in one direction, and the end surfaces of the protrusions 932 are the first cavity 911 and the second cavity 912. The tray 92 is locked to the boundary wall 914, and the tray 92 becomes a stop position where it is difficult to reversely move.

  When the tray 92 is pushed back again, the rotating cam member 93 rotates in one direction, and the protrusion 932 engages with the grooves 911a, 911b, and 911c to push out the tray 92, and the card can be discharged.

  However, in the card connector according to Patent Document 2, when the card is ejected, the compression coil spring urges the tray 92 through the rotating cam member 93. Therefore, when the tray 92 stops, However, there is a problem that it jumps out of the tray 92 due to inertial force.

  By reducing (weakening) the “spring constant” of the compression coil spring, the card can be prevented from popping out, but another problem arises that the card is not easily separated from the plurality of contacts.

  In addition, it is actually difficult to determine the “spring constant” of the compression coil spring by balancing the two because various factors are involved. It is preferable to devise the structure of the card connector to prevent the card from popping out carelessly. The above can be said to be the subject of the present invention.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a card connector that prevents a card from popping out carelessly.

  The present inventors have found that this problem can be solved by providing the housing with brake means for relaxing the initial speed of the rotating cam member, and based on this, the following new card connector has been invented. It came to do.

And the housing has a first linear groove and a second linear groove for guiding the first protrusion and the second protrusion, which are opposed to each other along the longitudinal direction of the slider, and the slider has The rotary cam member has a plurality of protrusions that protrude radially in a direction substantially perpendicular to the longitudinal direction of the slider and that can contact the edge of the card. It is a ridge , A plurality of ridges provided alternately with a wide first ridge and a narrow second ridge, and a plurality of ratchet-shaped first ridges provided on one end of the shaft and projecting in the axial direction A tooth, and an end surface that is provided at the other end of the shaft portion and is in contact with the other end of the urging means, and the housing has an inferior arc groove that receives an outer periphery of the shaft portion, A passage groove communicating with the first linear groove guiding the first protrusion and allowing only one of the second protrusions to pass therethrough, and a pair of first inclined surfaces formed on both wings at the start end of the passage groove A pair of first inclined surfaces intersecting the same direction at a predetermined angle with the advancing / retreating direction of the rotating cam member, and the slider opens in the outer peripheral direction to hold the outer periphery of the shaft portion And a plurality of ratchets that mesh with the first angle teeth and intermittently rotate the rotating cam member in one direction A second chevron, and the first ridge and the second ridge contact a pair of the first inclined surfaces to intermittently rotate the rotating cam member in one direction. An inclined surface is provided in the direction in which the first chevron protrudes, the passage groove prevents the first protrusion from entering, and has a width wider than the width of the second protrusion. A receiving opening for facilitating the entry of the second protrusion, the tip of the second protrusion contacting the receiving opening, and moving the second protrusion from one inner wall to the other inner wall A card connector in which a third inclined surface that is advanced toward the end of the passage groove is provided on the one inner wall.

  The card connector according to the present invention includes a flat housing, a cover, and a strip slider. The housing is provided with a recess into which the card is inserted. The cover has a flat surface that covers the recess of the housing. The slider is disposed on one wing of the recess of the housing. In addition, the slider is allowed to move forward and backward substantially in parallel with the card insertion direction.

  The card connector according to the present invention includes a rotating cam member and a biasing means. The rotating cam member is held by a slider, and can move slightly while moving in the axial direction. The biasing means biases the force in the direction in which the card ejects the rotating cam member.

  The housing has a first straight groove and a second straight groove. The first linear groove and the second linear groove guide the first protrusion and the second protrusion that are disposed to face each other along the longitudinal direction of the slider. The slider has a flange. The flange piece protrudes in a direction substantially orthogonal to the longitudinal direction of the slider, and the edge of the card can come into contact therewith.

  The rotating cam member has a plurality of protrusions, a plurality of ratchet-shaped first chevron teeth, and an end surface. The plurality of protrusions protrude radially from the outer periphery of the columnar shaft portion. The plurality of ridges are alternately provided with wide first ridges and narrow second ridges. The first chevron is provided at one end of the shaft and protrudes in the axial direction. The end surface is provided at the other end portion of the shaft portion, and the other end portion of the urging means contacts.

  Furthermore, the housing is provided with an inferior arc groove, a passage groove, and a pair of first inclined surfaces. The subarc groove receives the outer periphery of the shaft portion. The passage groove communicates with the first linear groove that guides the first protrusion, and only one of the second protrusions can pass therethrough. The pair of first inclined surfaces are formed on both blades at the start end of the passage groove, and intersect the advance direction of the rotating cam member in the same direction at a predetermined angle.

  The slider is provided with a bearing portion and a plurality of ratchet-shaped second chevron teeth. The bearing portion is open in the outer peripheral direction and holds the outer periphery of the shaft portion. The second chevron teeth mesh with the first chevron teeth to intermittently rotate the rotating cam member in one direction.

  Each of the first and second protrusions is provided with a second inclined surface in the direction in which the first chevron protrudes. The second inclined surface is in contact with the pair of first inclined surfaces and intermittently rotates the rotating cam member in one direction.

  The passage groove has a receiving opening on the start end side. The receiving opening prevents the first protrusion from entering and has a width wider than the width of the second protrusion, facilitating the entry of the second protrusion. And the receiving opening has provided the 3rd inclined surface in one inner wall. The third inclined surface advances toward the end of the passage groove while the tip of the second protrusion abuts and moves the second protrusion from one inner wall to the other inner wall.

  Here, the housing preferably has an insulating property. The insulating housing may be a housing made of a non-conductive material, and a synthetic resin can be molded to obtain an insulating housing having a desired shape.

  For example, the housing may include a pair of arms extending substantially in parallel from the base end portion to the tip end portion, and a connecting portion that connects the pair of arms, and the pair of arms are opposed to each other. In addition, grooves extending from the distal end portion to the proximal end portion may be provided, and both wings of the card are guided in these grooves so that the card can be accommodated in the housing.

  Multiple contacts may be fixed to the base end of the housing by press-fitting or molding (integral molding), one end of the contact may contact the card terminal (electrical terminal), and the other end of the contact soldered to the printed circuit board It is preferable to be joined. The other end of the contact may be solderlessly connected to the printed circuit board.

  The contact may be a pin contact, a socket contact, or a plate contact having springiness such as a cantilever contact. An appropriate contact is selected in accordance with the type of terminal provided on the card.

  The cover is made of, for example, a thin metal plate, and a cover having a desired shape can be obtained by molding the developed thin metal plate. The cover is preferably made of a conductive thin metal plate, and a shielding effect is obtained when the flat surface of the cover covers the housing. In addition, since the flat surface of the cover covers the housing, the slider can be prevented from being lifted.

  The cover may be bent at substantially right angles to form a pair of both wing pieces, and an opening is formed in each of the wing pieces and can be locked to protrusions protruding on both side surfaces of the housing. Further, the cover may be provided with a plurality of lead terminals soldered to the printed circuit board on both wing pieces, and the card connector can be surface-mounted on the printed circuit board.

  The bearing portion is preferably slightly larger than the diameter of the shaft portion and opens in the outer circumferential direction. The shaft portion can be inserted from the outer circumferential direction to hold the shaft portion. The inferior arc groove is opened smaller than the diameter of the shaft portion, and can partially support the outer periphery of the shaft portion without contacting the bearing portion.

  The slider and the rotating cam member constitute an intermittent motion device. The bearing portion and the plurality of second angle teeth are arranged opposite to each other while sharing the center of the shaft, and the first angle teeth move forward and backward with respect to the second angle teeth, so that the rotating cam member is intermittently moved in one direction. Can be rotated. It can also be said that the slider and the rotating cam member constitute a three-dimensional cam device in which the rotating cam member rotates while moving forward and backward.

  In a state where the card is not inserted into the card connector, the slider is urged by the urging means (substantially, a compression coil spring) and moves to the front end side of the housing and stops (waiting). )

  In this standby state, the first angle teeth are biased by the biasing means, and a force directed toward the second angle teeth is applied. Further, in this standby state, the first angle teeth slightly mesh with the second angle teeth, and the rotating cam member is given a force to rotate in one direction, but the first protrusion is restricted in the passage groove. Thus, the rotation of the rotating cam member is stopped.

  When the card is inserted into the card connector, the edge of the card comes into contact with the flange, and the slider and the rotating cam member can be moved to the base end side. In this moving process, the first chevron teeth are slightly meshed with the second chevron teeth, and the rotating cam member is given a force to rotate in one direction, but the second protrusion is restricted in the passage groove. The rotation of the rotating cam member is stopped.

  When the card is pushed all the way to the base end side of the recess, the slider stops, and the movement of the rotating cam member in the axial direction is converted into a rotational movement in which the first angle teeth and the second angle teeth mesh. That is, the rotating cam member rotates intermittently in one direction.

  When the card is released from the state where the card is pushed all the way to the base end side of the recess, the rotating cam member is urged by the urging means and moves to the initial state. And a 2nd inclined surface contact | abuts to a 1st inclined surface, and a rotating cam member further rotates intermittently.

  In this state, since the wide first protrusion is opposed to the start end of the passage groove, it is difficult to move the rotating cam member. In this state, it can also be said that the wide first protrusion is opposed to the receiving opening that prevents the first protrusion from entering, and it is difficult to move the rotating cam member. That is, the slider is locked with respect to the housing.

  From this locked state, when the card is pushed all the way to the base end side of the concave portion, the first angle teeth and the second angle teeth mesh with each other, and the rotating cam member rotates intermittently in one direction. When the card is released, the second inclined surface comes into contact with the first inclined surface, and the rotating cam member further rotates intermittently.

  In this state, since the narrow second protrusion is opposed to the start end of the passage groove, the rotating cam member can be moved. In this state, it can also be said that the narrow second protrusion is opposed to the receiving opening that facilitates the entry of the second protrusion, and the rotating cam member can be moved. In other words, the card can be drawn from the card connector and ejected from the card connector.

  Thus, the card connector according to the present invention is locked when the card is inserted (pushed) into the connector, and when the card is pressed, the lock is released and the card is ejected from the connector. Is realized.

  In the card connector according to the present invention, the tip of the second protrusion abuts, and the second protrusion is advanced toward the end of the passage groove while moving the second protrusion from one inner wall of the receiving opening to the other inner wall. Since the three inclined surfaces are provided on one inner wall of the receiving opening, the initial speed of the rotating cam member can be reduced. Therefore, it is possible to prevent the card from popping out carelessly.

  In the card connector according to the present invention, the tip of the second protrusion abuts, and the second protrusion is advanced toward the end of the passage groove while moving the second protrusion from one inner wall of the receiving opening to the other inner wall. Since the three inclined surfaces are provided on one inner wall of the receiving opening, the initial speed of the rotating cam member can be reduced. Therefore, it is possible to prevent the card from popping out carelessly.

  Referring to FIGS. 5, 6, and 12, the first chevron 73 is biased by the compression coil spring 8 and is given a force toward the second chevron 55. In the state shown in FIG. 6, the first chevron teeth 73 slightly mesh with the second chevron teeth 55, but the rotation of the rotary cam member 7 is stopped.

  Referring to FIG. 10, the rotary cam member 7 is biased by the compression coil spring 8 and is given a force to move toward the distal end side of the housing 1, but the wide first protrusion 71 has a receiving opening. 18, the first protrusion 71 is prevented from entering. Therefore, it is difficult to move the rotating cam member 7. That is, the slider 5 is locked with respect to the housing 1.

  Note that the round mark M shown in FIGS. 12 to 15 represents the rotation direction and the rotation order of the rotary cam member 7 for convenience of explanation, and the round mark M is provided as an entity. Absent.

  Referring to FIGS. 5, 7, and 13, next, when the card 1 c is pushed all the way to the base end side of the recess 10, the slider 5 stops and the movement of the rotary cam member 7 in the axial direction is the first. It is converted into a rotational movement in which the chevron 73 and the second chevron 55 mesh. That is, the rotating cam member 7 is intermittently rotated in one direction.

  Referring to FIGS. 5 and 8, when the card 1 c is released from a state where the card 1 c is pushed to the base end side of the recess 10, the rotary cam member 7 is urged by the compression coil spring 8. Move to the tip side. And the 2nd inclined surface 722 of the 2nd protrusion 72 contact | abuts to the 1st inclined surface 15 of the passage groove | channel 14, and the rotating cam member 7 rotates further intermittently. FIG. 8 is a state diagram immediately before the rotating cam member 7 rotates further intermittently.

  Referring to FIGS. 9 and 14, when the rotating cam member 7 is rotated by one index, the narrow second protrusion 72 is opposed to the start end of the passage groove 14 (receiving opening 18). The member 7 can be moved. That is, the card 1c is dragged by the flange 53, and the card 1c can be discharged from the card connector 100.

  Referring to FIG. 9, the tip of the second ridge 72 is in contact with the third inclined surface 18a. Then, the tip of the second ridge 72 slides to the third inclined surface 18 a, moving the second ridge 72 from one inner wall of the receiving opening 18 to the other inner wall, toward the end of the passage groove 14. (See FIG. 10).

  In the process from FIG. 9 to FIG. 10, the tip of the second ridge 72 abuts against the third inclined surface 18 a, so that the initial speed of the rotating cam member 7 can be relaxed. Therefore, it is possible to prevent the card 1c from popping out carelessly.

  FIG. 10 is a state diagram in which the card 1c is not inserted into the connector 100, and the slider 5 is biased by the compression coil spring 8 and moves to the front end side of the housing 1 to stand by. .

  In the standby state shown in FIG. 10, the first angle tooth 73 is biased by the compression coil spring 8 and is given a force toward the second angle tooth 55. In this standby state, the first chevron 73 is slightly meshed with the second chevron 55 and the rotating cam member 7 is given a force to rotate in one direction. The protrusion 72 is restricted, and the rotation of the rotating cam member 7 is stopped.

  Referring to FIG. 14, when the card 1 c is pushed all the way to the base end side of the recess 10, the slider 5 stops and the movement of the rotary cam member 7 moving in the axial direction causes the first chevron 73 and the second chevron 55. Is converted into a rotating motion that meshes. That is, the rotating cam member 7 is intermittently rotated in one direction.

  Next, when the card 1c is released from the state in which the card 1c is pushed to the proximal end side of the recess 10 (see FIG. 11), the second inclined surface 712 of the first protrusion 71 contacts the first inclined surface 15. Thus, the rotating cam member 7 is further intermittently rotated to be in the locked state shown in FIGS.

  As described above, the connector 100 according to the embodiment of the present invention is a push-push type card connector in which the card is locked when the card is pushed to the connector, and the card is released from the lock when the card is pushed. Realized.

  In the connector 100 according to the embodiment of the present invention, the tip of the second ridge 72 abuts and the second ridge 72 is moved from one inner wall of the receiving opening 18 to the other inner wall, while passing through the groove 14. Since the third inclined surface 18a that advances toward the terminal end is provided on one inner wall of the receiving opening 18, the third inclined surface 18a serves as a brake, and the initial speed of the rotating cam member 7 can be reduced. . Therefore, it is possible to prevent the card from popping out carelessly.

  Furthermore, the connector 100 according to the embodiment of the present invention can be assembled so that the housing 1, the rotating cam member 7, and the slider 5 are stacked, and a card connector that can be easily assembled can be provided.
