Description

  The invention described in the claims of the present application relates to a connector device that is used as a receptacle connector that is attached to a wiring board such as a solid wiring board and is connected to a plug connector to which a plurality of coaxial cables are connected.

  When connecting a plurality of relatively thin coaxial cables to a wiring board to which various electrical components are attached, a plug connector to which the plurality of coaxial cables are connected and an electrical connection between the wiring board and the wiring board. And a receptacle connector into which a plug connector to which a plurality of coaxial cables are connected is fitted and connected is often used.

  In such a case, the receptacle connector is formed on the wiring board, for example, to form a fitting recess into which a fitting projection provided in the plug-side insulating housing of the plug connector is extended in the longitudinal direction. An insulating housing is provided. The fitting recess formed by the insulating housing extends in the longitudinal direction of the insulating housing. A plurality of signal contacts respectively connected to the plurality of signal terminal portions provided on the wiring board are arranged and arranged along the fitting recesses on the insulating housing. In many cases, such a receptacle connector partially covers the outer surface of the peripheral portion of the fitting recess in the insulating housing, and is connected to the ground connection portion in the wiring board to provide a ground potential. Is provided.

  Then, the fitting convex portion provided in the insulating housing of the plug connector to which a plurality of coaxial cables are connected is inserted into the fitting concave portion formed by the insulating housing of the receptacle connector, and the receptacle connector is engaged with the plug connector. When placed in a connected state, a plurality of signal contacts are contact-connected to a plurality of plug-side signal contacts of a plug connector to which each signal conductor (center conductor) of a plurality of coaxial cables is connected, and a ground contact is also connected. The conductors are connected to the respective ground conductors (outer conductors) of the plurality of coaxial cables through, for example, a conductive shell and a plug-side conductive shell of the plug connector. Thereby, the signal conductor in each of the plurality of coaxial cables connected to the plug connector is connected to the signal terminal portion provided on the wiring board on which the receptacle connector is mounted via the plug connector and the receptacle connector, and A ground conductor in each of the plurality of coaxial cables connected to the plug connector is connected to a ground connection portion on the wiring board on which the receptacle connector is mounted via the plug connector and the receptacle connector.

  In such a receptacle connector, the conductive shell serves to connect the ground conductor in each of the plurality of coaxial cables connected to the plug connector to the ground potential portion in the wiring board via the plug-side conductive shell, for example. Therefore, the conductive shell is usually connected to the wiring board through the ground connection terminal portion provided at both ends in the direction in which the fitting recess formed by the insulating housing extends (arrangement direction of the plurality of signal contacts). Is connected to a ground connection portion included in the ground potential portion. As described above, both ends of the conductive shell in the extending direction of the fitting recess are connected to the ground connection portion of the wiring board via the ground connection terminal portion, and arranged in the receptacle connector along the fitting recess. This is because the connection of the plurality of signal contacts to the plurality of signal terminal portions provided on the respective wiring boards is not hindered.

  However, if both ends of the conductive shell in the direction in which the fitting concave portion extends are connected to the ground connection portion in the wiring board, the ground connection is made between both ends in the direction in which the fitting concave portion of the conductive shell extends. When a high-frequency signal transmitted by the coaxial cable acts on such a part, a small potential difference appears between the ground connection part and the coaxial cable signal. There is a possibility that good ground characteristics for the signal contact connected to the conductor cannot be obtained. Therefore, it is conceivable to provide ground connection terminal portions on the conductive shell at portions other than both ends. However, in order to further reduce the size and thickness of the receptacle connector, the conductive shell The ground connection terminal portion provided in the case is subject to severe restrictions on the arrangement position and the number of the ground connection terminal portions, and it is difficult to provide the ground connection terminal portion in portions other than both ends of the conductive shell.

  Therefore, a receptacle connector having a conductive shell that partially covers the outer surface of an insulating housing in which a plurality of contacts are arranged and arranged, not only for both ends of the plurality of contacts in the arrangement direction, Conventionally proposed is also one in which a plurality of locations between both end portions are devised to be connected to a ground potential portion in a wiring board on which an insulating housing is arranged (see, for example, Patent Document 1). .

  In the conventionally proposed receptacle connector (11) disclosed in the above-mentioned Patent Document 1, a plurality of terminals (contacts) arranged and arranged along the longitudinal direction of the insulating housing (12) are provided. Some of (13) are ground terminals (ground contacts) connected to the ground circuit (ground potential portion) of the printed circuit board (wiring substrate). Lead pieces (19) are formed at locations corresponding to the ground terminals in the shield (conductive shell) (14) partially covering the outer surface of the insulating housing (12), and these lead pieces ( 19) is elastically engaged (contact engagement with elasticity) to the terminal (13), which is the ground terminal, so that the shield (14) is made the ground terminal via the lead piece (19). Electrically connected to the terminal (13). As a result, the portion of the shield (14) between the ends in the arrangement direction of the plurality of terminals (13) is connected to the ground circuit of the printed circuit board via the terminal (13) that is the ground terminal. Become.

Since this is taken through the contact engagement between the lead piece and the ground contact, there is a disadvantage that the certainty and stability of the lead piece depend on the contact state of the lead piece with the ground contact. For example, due to the mutual positional relationship between the lead piece and the ground contact and the degree of elastic force that the lead piece exerts on the ground contact, the contact of the lead piece with the ground contact exerts a sufficient pressing force on the ground contact. If the process is performed without the use of a fine foreign matter between the lead piece and the ground contact, the electrical resistance between the lead piece and the ground contact is increased, resulting in conductivity. The connection state between the shell and the ground potential portion in the wiring board is not reliably and stably performed.

  For example, the ground contacts are arranged at the center of the arrangement of the plurality of signal contacts, or a plurality of the ground contacts are arranged at predetermined intervals in the arrangement of the plurality of signal contacts. Along with this, the ground connection piece formed on the conductive shell is, for example, formed at the central portion between both ends in the arrangement direction of the plurality of signal contacts in the conductive shell, or a plurality of the ground connection pieces are formed. It is assumed that the conductive shells are formed at predetermined intervals between both ends in the arrangement direction of the plurality of signal contacts.

Therefore, according to the connector device 10, the conductive shell 13 is connected to, for example, the ground potential portion of the connector mounting wiring board at both ends in the longitudinal direction of the housing, and in addition, the portion located between the both ends. In addition, it is assumed that the ground potential is applied to both ends of the housing in the longitudinal direction of the housing and the portion between them as being connected to the ground terminal portion 20 included in the ground potential portion of the connector-mounted wiring board. . As a result, the conductive shell 13 exhibits excellent ground characteristics for the plurality of signal contacts 17.

  Further, in the connector device 10, a state in which the portion between both ends in the housing longitudinal direction in the conductive shell 13 is connected to the ground potential portion in the connector mounting wiring board is in the housing longitudinal direction in the conductive shell 13. Since the ground connection piece portion 23 formed between both end portions is obtained by being soldered to the ground terminal portion 20 included in the ground potential portion in the connector mounting wiring board together with the ground contact 18, for example, the connector device 10 Even if the size and thickness are further reduced and the ground connection terminal portion provided on the conductive shell 13 is subject to severe restrictions on the arrangement position and number, the housing in the conductive shell 13 is provided. The portion between both ends in the longitudinal direction is the ground on the connector-mounted wiring board. It will be reliably and stably connected to the potential portion.

  Further, in the connector device 10, the ground contact 18 and the ground connection piece 23 are not particularly restricted with respect to the arrangement position in the longitudinal direction of the housing. An arbitrary portion corresponding to the position of the terminal portion 20 can be a connection portion with the ground potential portion in the connector-mounted wiring board.

  The connector device according to the present invention as described above is, for example, a connector device that can be used as a receptacle connector that is attached to a wiring board and in which a plug connector is fitted and connected, and a plurality of signals in a conductive shell. It can be widely applied to various electronic devices and the like, as the portion between both ends in the contact arrangement direction is reliably and stably connected to the ground potential portion of the wiring board.
