Description

Wire to substrate connector

The present invention relates to a connector for a wire to substrate.

As such a technique, a flexible cable connection structure is disclosed in the patent document 1 (Japanese Patent Laid-Open Publication No. 2010-267411), which is constructed to be formed on a flexible cable. When the terminal portion 501 of the end portion of the 500 is inserted into the cable insertion opening 503 of the flexible cable connector 502, a plurality of connector pins 504 provided on the upper side of the cable insertion opening 503 are connected to the terminals. Part 501. In the locking groove 505 on the right and left sides of the flexible cable connector 502, a metal L-shaped bracket 506 for locking the flexible cable connector 502 to the printed circuit board is press-fitted.

However, the inventors of the present invention have developed an electrical connector in the form of a receptacle connector on the side of the substrate from the cable side connector. In this electrical connector, the latch connector is provided with an arm having a claw formed at its front end. When the latch connector is fitted to the receptacle connector, the pawl flexes the arm in contact with the left and right sides of the receptacle connector, and the pawl slides on the left and right sides of the receptacle connector. Furthermore, when the claws When the left and right sides of the socket connector pass, the claw is elastically changed to the back side of the socket connector due to the elastic restoring force of the arm.

However, when the flexible cable connector 502 disclosed in Patent Document 1 is to be used, the claws are passed over the flexible cable due to the presence of the locking groove 505 formed on the right and left sides of the flexible cable connector 502. Before the left and right sides of the connector 502, the claws are elastically displaced into the locking groove 505 due to the elastic restoring force of the arms. Therefore, when the claw is elastically displaced into the locking groove 505 due to the elastic restoring force of the arm, the claw is elastically displaced to the back side of the flexible cable connector 502. Furthermore, the misidentification will call the inaccurate fitting of the connector.

(10) The wire-to-substrate connector 1 includes a pin connector 4 having a pin housing 8 for holding the electric wire 2, and a socket connector 6 having a socket contact portion 9 corresponding to the electric wire 2, and The socket housing 10 of the socket contact portion 9 is held and mounted on the connector mounting surface 5 of the substrate 3. By fitting the latch connector 4 toward the receptacle connector 6, the electric wire 2 and the socket contact portion 9 are electrically connected. The fitting direction in the direction in which the plug connector 4 is fitted to the receptacle connector 6 is parallel to the connector mounting surface 5 of the substrate 3. A pair of locking pieces 17 extending in the fitting direction are formed in the plug housing 8. Each of the lock pieces 17 is configured to have an arm portion 20 that extends in the fitting direction and a claw portion 21 that is formed at the end portion 20a of the arm portion 20 in the fitting direction. The latch connector 4 is configured to be fixed to the receptacle connector 6 in such a manner that one of the latch connectors 4 sandwiches the receptacle connector 6 with the locking piece 17. The socket connector 6 has an auxiliary metal fitting 11 for fixing the socket housing 10 to the connector mounting surface 5 of the substrate 3. A slit g extending in a direction in which the auxiliary metal fitting 11 is attached to the socket housing 10 in a direction orthogonal to the connector mounting surface 5 of the substrate 3 is formed in the side wall 32 of the socket housing 10. The auxiliary metal part 11 further has a slit covering portion 94 that shields the slit g. According to the above configuration, the claw portions 21 of the respective locking pieces 17 can smoothly advance in the fitting direction. Therefore, since the dissimilarity of the claw portions 21 of the respective locking pieces 17 in the fitting direction is suppressed, the fitting of the plug connector 4 and the receptacle connector 6 is prevented.

Although the fourth embodiment of the present invention has been described above, the fourth embodiment described above can be modified as follows.

In other words, as shown in the second embodiment, the first one may be provided. The folded portion 93 protrudes more toward the plucking direction than the socket housing 10.

Further, the second folded portion 85 and the hook portion 86 of the third embodiment described above can be applied to the auxiliary metal fitting 11 of the present embodiment within a reasonable range.

Further, in Fig. 39, the direction in which the gap between the slit covering portion 94 of the auxiliary metal fitting 11 and the rear L-shaped portion 37 extends in the direction in which the connector is attached is preferably inclined in the direction orthogonal to the substrate. . At this time, the claw portions 21 of the respective locking pieces 17 are more smoothly advanced.
