  The fitting lock piece 90 provided with the lock hole 91 of Patent Document 1 is understood to be made of metal since it is formed by bending the receptacle shell 70. It is understood that the lock lever having the lock portions 25 and 26 engaged with the lock hole 91 is also made of metal like the lever 140 of Patent Document 2. Further, since the hook portion 34a of Patent Document 3 is made of metal, the mating engagement portion 61b in which the mating engagement hole 61c that engages with the hook portion 34a is also formed by the hook portion 34a. In order to avoid this, for example, a part of the shell of the mating connector 61 is generally used and formed of metal.

  In this way, in the pair of shield connectors, the lock lever or the lock member and the fitting lock piece or the mating engagement portion are not formed of metal, but a housing in which the lock lever and the lock lever are engaged is provided. To obtain a fitting feeling and fitting sound that are different from those formed from synthetic resin and metal, the synthetic resin lock lever of one shield connector is provided in the synthetic resin housing of the other shield connector. It will be engaged with the lock hole. In that case, in order to enable engagement of the lock claw with the lock hole, a through-hole is provided in the shell covering the housing, but in this case, the shield function by the shell is impaired at the portion of the through-hole. . Therefore, like the receptacle connector of the above cited reference 4, another shield is provided outside the housing and shell, and the shield function impaired by providing an opening in the inner shell is compensated by the outer shell. Conceivable. However, if it does so, the increase in the cost and enlargement of a shield connector will be caused by providing a shell on the outside. There is also a demand for avoiding damage to the lock lever due to external force.

The present invention has been made paying attention to such points, and the purpose thereof is to engage the synthetic resin lock lever of one shield connector with the inside of the synthetic resin housing of the other shield connector. This prevents an increase in cost and size, and prevents the lock lever from being damaged by an external force, and provides a unique fitting feeling and fitting sound due to the synthetic resin lock lever and the synthetic resin housing. In addition, it is possible to amplify the sound of the locking lever to detect the completion of mating of both connectors, prevent the occurrence of poor connection due to half mating, and forcefully push the connector in the mating direction. to provide a pair of shielded connector that can be performed connector to prevent damage and more reliably.

In order to achieve the above object, a pair of shielded connectors according to the present invention includes a first connector and a second connector to be fitted to the first connector,
The first connector is formed of a synthetic resin and has a first housing formed with a recess recessed inward from the surface on the fitting side. The first connector is formed of a conductive material and is formed on the first housing with the outer surface of the first housing. A first shell provided so as to cover the surface, a connection formed by a conductive material and provided in the first housing, with one end disposed as a contact portion inside the recess and the other end connected to the outside A first contact disposed in the first housing as a part,
The second connector is formed of a synthetic resin and has a housing main body, a second housing that protrudes from the housing main body toward the fitting side, and can be inserted into the concave portion and removed from the concave portion, and conductive A second shell formed of a conductive material so as to cover the outer surface of the housing body, and a second shell formed of a conductive material and provided on the second housing. A second contact disposed on the second housing as a connection portion disposed on the convex portion as a contact portion to be in contact with the contact portion and connected to the outside at the other end;
The convex part of the second housing has a convex part main body and has flexibility and extends from the tip of the convex part main body on the mating side to the non-fitting side. A lock lever provided so as to come out from the concave portion of the first connector when the second connector is fitted to the first connector,
At the time of fitting the second connector to the first connector in the portion of the lock lever between the fitting end and the non-fitting end and the wall constituting the recess of the first housing Of the part of the lock lever facing the part, a lock claw protruding toward the other part is provided at one part, and a lock hole into which the lock claw can be fitted is formed at the other part. Has been
The first connector is provided with a cavity communicating with the lock hole,
The lock lever is bent so as to approach the convex body as the convex portion is inserted into the concave portion, and then restored so that the lock claw fits into the lock hole, and the operating portion approaches the convex body. When the lock lever is bent so as to be bent, the lock claw is pulled out from the lock hole, and when the lock lever is restored, a hitting sound generated when the lock lever hits the back wall is generated. It is configured to resonate with .

  When fitting the second connector to the first connector, when the convex portion of the second connector is inserted into the concave portion of the first connector, the lock lever is bent so as to approach the convex body. By restoring, the lock claw fits into the lock hole, and the contact portion of the second contact contacts the contact portion of the first contact. Further, when the second connector is separated from the first connector, the lock claw comes out of the lock hole when the operation lever is pushed close to the convex body to bend the lock lever, and the second connector It is possible to remove the convex portion from the concave portion of the first connector.

  When the second connector is fitted into the first connector, when the lock lever is bent so as to approach the convex body and then restored, the lock lever strikes the wall that forms the concave portion. In that case, since both the lock lever and the wall are made of synthetic resin, the fitting feeling obtained from the second connector after the lock lever rubs the wall and hits the wall; The fitting sound generated when the lock lever strikes the wall is completely different from the case where both the lock lever and the wall are made of metal.

  In addition, since the lock claw and the lock hole are fitted and released inside the recess, the lock claw and the lock hole are fitted to the first shell and the second shell. There is no need to provide an opening. Therefore, it is possible to enhance the shielding function by the first shell and the second shell. In this case, unlike the receptacle connector of the above cited reference 4, it is not necessary to provide another shell outside the housing and the shell, so that an increase in cost and an increase in size of the shield connector can be prevented. Further, when the second connector is fitted to the first connector, the lock lever is received in the recess, so that there is no possibility that the lock lever is damaged by receiving an external force.

Furthermore, since the first connector is provided with a cavity that communicates with the lock hole, when the second connector is fitted to the first connector, the lock lever is bent so as to approach the convex body. When restoration is performed from above, the lock lever strikes the back wall constituting the recess, and the sound is amplified because the hitting sound resonates in the cavity. Therefore, the completion of the fitting of both the connectors is more reliably detected, and the occurrence of poor connection due to the half-fitting is prevented, and the damage of the connector is prevented more reliably by forcibly pushing the connector in the fitting direction.

In the pair of shielded connectors according to the present invention, the synthetic resin lock lever of the second connector is engaged with the wall constituting the concave portion of the first housing made of synthetic resin of the first connector. And the lock lever can be prevented from being damaged by an external force, and a unique fitting feeling and fitting sound can be obtained by the synthetic resin lock lever and the synthetic resin housing . Amplifying the tapping sound to detect the completion of mating of both connectors more reliably, preventing the occurrence of connection failure due to half mating, and preventing connector damage by forcibly pushing the connector in the mating direction. Ru can be done.

A lock mechanism is provided at a portion of the lock lever 212b that faces the portion of the lock lever 212b when fitted. That is, the lock claw 212bb is provided at the part of the lock lever 212b so as to protrude toward the part of the recess forming wall when the fitting is performed. The lock claw 212bb protrudes away from the convex body 212a. Further, a lock hole 111a into which the lock claw 212bb can be fitted at the time of the fitting is formed in the portion of the wall constituting the recess. In this embodiment, the portion on the back side in the depth direction in the central portion 212B is the lock lever 212b, so the lock hole 111a is provided in the back wall 111 of the first housing. The lock hole 111 a passes through the back wall 111. As the protrusion 212 is inserted into the recess 116, the lock lever 212b is bent so as to approach the protrusion body 212a and then restored, so that the lock claw 212bb fits into the lock hole 111a and the operation is performed. The lock claw 212bb is configured to be removed from the lock hole 111a when the lock lever 212b is bent by pushing the portion 212ba closer to the convex body 212a. In this embodiment, since the lock lever 212b is provided on the back side in the depth direction of the convex part 212, the lock hole 111a is provided in the back wall 111. However, the lock lever is provided in another part of the convex part. In some cases, the lock hole is provided in the wall of the recess that faces the lock lever. Contrary to this embodiment, a lock claw that protrudes toward the part of the lock lever is provided at the part of the wall that constitutes the recess, and the lock claw fits into the part of the lock lever. A possible lock hole may be formed. The lock hole 111a penetrates the back wall 111, but the lock hole may be formed by simply denting the wall constituting the recess without penetrating it.

  The first connector 100 is provided with a cavity 140 that communicates with the lock hole 111a, and the hitting sound generated when the lock lever 212b hits the back wall 111 when the lock lever 212b is restored is The cavity 140 is configured to resonate. The cavity 140 is formed between the outer surface of the back wall 111 of the first housing 110 and the first shell 120. However, the cavity may be formed inside the first housing. In that case, the lock hole is formed only by being recessed without penetrating the wall constituting the recess, and the lock hole is communicated with the cavity on the side far from the recess. In addition, when the lock hole is provided in another wall among the walls constituting the recess, the cavity is formed between the outer surface of the other wall and the first shell 120, or another wall. Provided inside.

  Next, operations and effects of the pair of shield connectors of the above embodiment will be described. When the second connector 200 is fitted to the first connector 100, when the convex portion 212 of the second connector 200 is inserted into the concave portion 116 of the first connector 100, the lock lever 212b is moved to the convex main body. The lock claw 212bb fits into the lock hole 111a by bending after approaching to 212a, and the contact portion 231 of the second contact 230 contacts the contact portion 131 of the first contact 130. Further, when the second connector 200 is separated from the first connector 100, the lock claw 212bb is bent into the lock hole 111a by pushing the operation portion 212ba closer to the convex body 212a and bending the lock lever 212b. And the convex portion 212 of the second connector 200 can be removed from the concave portion 116 of the first connector 100.

  When the second connector 200 is fitted to the first connector 100, when the lock lever 212b is bent so as to approach the convex body 212a and then restored, the lock lever 212b forms the concave 116. Hit the back wall 111. In that case, since both the lock lever 212b and the back wall 111 are formed of a synthetic resin, the second connector is between the time when the lock lever 212b rubs the back wall 111 and hits the back wall 111. 200 and the fitting sound generated when the lock lever 212b hits the back wall 111, both the lock lever 212b and the back wall 111 are made of metal. It will be totally different. Therefore, the unique fitting feeling and fitting sound by the synthetic resin lock lever and the synthetic resin housing can be obtained.

  In addition, since the lock claw 212bb and the lock hole 111a are fitted and released inside the recess 116, the lock claw 212bb and the lock hole 111a are connected to the first shell 120 and the second shell 220, respectively. It is not necessary to provide an opening for fitting the. Therefore, the shielding function by the first shell 120 and the second shell 220 can be enhanced. In this case, unlike the receptacle connector of the above cited reference 4, it is not necessary to provide another shell outside the housing and the shell, so that an increase in cost and an increase in size of the shield connector can be prevented. Further, when the second connector 200 is fitted to the first connector 100, the lock lever 212b is received in the recess 116, so that the lock lever 212b is not damaged by receiving an external force.

  In the first embodiment, the first connector 100 is provided with the cavity 140 communicating with the lock hole 111a. In this way, when the second connector 200 is fitted to the first connector 100, the lock lever 212b is deformed so that the lock lever 212b is bent so as to approach the convex body 212a. The back wall 111 constituting 116 is struck, and this struck sound resonates in the cavity 140, so that the sound is amplified. Therefore, the completion of the fitting of both the connectors is more reliably detected, and the occurrence of poor connection due to the half-fitting is prevented, and the damage of the connector is prevented more reliably by forcibly pushing the connector in the fitting direction.

  5 and 6 show a second embodiment of a pair of shielded connectors according to the present invention. In this embodiment, the configurations of the first embodiment and the modifications thereof are cited as they are, and a configuration different from the configuration of the first embodiment in the second embodiment will be additionally described. In the case of the first embodiment, the first connector 100 faces the first member 300 such that the bottom wall 115 faces the surface of the first member 300, that is, the first connector 100 and the second connector. The connector 200 was mounted such that the fitting / removing direction of the connector 200 was substantially orthogonal to the surface of the first member 300. On the other hand, in the case of the second embodiment, the first connector 100 faces the first member 300 such that the front wall 112 faces the surface of the first member 300, that is, the first connector 100. The second connector 200 is mounted such that the fitting / removing direction is substantially parallel to the surface of the first member 300. Therefore, in the first embodiment, since the second member 400 is pulled out to the near side in the depth direction, the second contact 230 is bent in the middle, but in the second embodiment, the second member 400 is Since the two members 400 are pulled out substantially in the fitting / removing direction, the second contact 230 is formed substantially straight.
