Description

  The present invention relates to a card connector for connecting a card such as an IC card or a flash memory card to a printed wiring board mounted on an electronic device such as a mobile phone or a smartphone.

  Conventionally, a card such as an IC card or a flash memory card has been used as an external storage medium of an electronic device such as a mobile phone or a smartphone, and this card and a printed wiring board mounted on the electronic device are electrically connected via a card connector. Connected.

  This type of card connector includes a housing having a card insertion portion into which a card such as an IC card is inserted, and a plurality of contacts made of a conductive metal plate having an elastic contact piece protruding from the bottom of the card insertion portion. By inserting the card into the card insertion portion, the signal transmission terminal (pad) formed on one side of the card comes into contact with the elastic contact piece of the corresponding contact, and electrically connects the printed wiring board and the card. It is like that.

  Also, in this type of card connector, the housing is configured by combining an insulating synthetic resin mold member and a shield cover made of a conductive metal material that covers the outside of the mold member, and electromagnetic noise is shielded by the shield cover. In addition, there is known one that reduces the influence of electromagnetic waves generated from the card when the card is used on other electronic components mounted on a printed wiring board (for example, see Patent Document 1).

  On the other hand, in this type of card connector, the total length in the card insertion / removal direction of a part or all of the shield cover is formed shorter than the total length of the card, and the rear end of the card is opened in the card insertion portion in a state where the card is inserted into the housing. A so-called Push-Pull type is known in which the card is pulled out from the housing by exposing the exposed portion to a more protruded state (see, for example, Patent Documents). 2).

  In this Push-Pull card connector, the card is exposed in a state of protruding from the opening of the card insertion portion, the exposed portion is used as a picking allowance, and the picking allowance is picked so that the card can be pulled out from the housing. As a result, there is no need to provide a special card removal mechanism, and there is an advantage that the card connector can be reduced in size and cost accordingly.

  However, in the conventional card connector as described above, in order to insert and remove the card, the rear end portion of the card insertion portion must be kept open, and therefore the rear end surface of the card must be shielded. I could not.

  Further, in the conventional card connector, when the front end portion of the card is exposed in a state of projecting horizontally from the front opening of the card insertion portion, the electromagnetic wave emitted from the exposed portion of the card can be completely shielded by the shield cover. The electromagnetic wave could not affect other electronic components mounted on the printed wiring board.

  In particular, in the conventional Push-Pull card connector described above, the rear end of the card must be exposed to a degree protruding from the opening of the card insertion portion in order to secure a handle for pulling out the card. In addition, electromagnetic waves leaking from the exposed portion (pinch allowance) may become a problem.

  On the other hand, with a conventional card connector, if a non-genuine card smaller in size than the applicable regular card is accidentally inserted into the card insertion section, the entire non-genuine card will be covered with a shield cover. There is also a problem that it is difficult to take out the picking allowance for pulling out.

And it can move between the open positions where the card A can be inserted into and removed from the card insertion portion 2 by being separated from the front portion of the fixed shield portion 6.

  As shown in FIG. 4, the mold member 5 is formed in a horizontally long rectangular parallelepiped shape with an insulating synthetic resin material, and includes a flat bottom plate portion 10 and side wall portions 11 and 12 disposed on the left and right side portions of the bottom plate portion 10. And a rear wall portion 13 having a shape raised from the rear edge of the bottom plate portion 10. The bottom plate portion 10 is surrounded by the side wall portions 11, 12 and the rear wall portion 13, and has a concave shape whose front and upper surfaces are open. A card insertion portion 2 is formed.

  Also, in this mold member 5, a plurality of contacts 4, 4... Oriented in the front-rear direction by insert molding are incorporated in the bottom plate portion 10 side by side in the connector width direction, and each contact 4, 4. .. Protrudes from the inner bottom surface of the portion 2 and comes into contact with the corresponding signal transmission pads a1, a1,... Arranged on the back side of one side of the inserted card A.

  Each of the contacts 4, 4... Is formed by punching and bending a conductive metal plate having elasticity, and ends are formed at the front and rear inner edges of the rectangular opening 14 formed in the bottom plate 10. A fixed piece 20 embedded in the bottom plate 10 in an arrangement that is embedded in the front and rear inner edges of the opening 14, and one end of which is integrally supported by the front end of the fixed piece 20, and has a letter-like elastic contact to the cantilever. A card 21 having a piece 21 and a board connecting piece 22 formed in a shape extending from the other end of the fixed piece 20, and the top of the elastic contact piece 21 forming a contact 21 a The elastic contact piece 21 is elastically deformed by being pressed against the surface of A, and the contact 21a comes into contact with the corresponding signal transmission pads a1, a1,.

  Note that reference numeral 23 in the figure denotes a card detection switch. When the card A is inserted into the card insertion portion 2, the switch terminal is pressed against the outer peripheral surface of the card A, and the switch terminal is elastically deformed. -The off state is switched.
