The present invention relates to an interengaging connector device.

  When connecting a plurality of relatively thin cables and a relatively small flexible printed circuit board to a circuit board on which various electrical components are mounted, the circuit board is electrically connected to the circuit board and fixed, for example, a receptacle. A first connector, which is a connector, and a plurality of cables or a flexible printed wiring board are connected to be engaged with and connected to the first connector, for example, a second connector which is a plug connector. There are many cases. In the first connector, for example, a fitting concave portion is provided, and a plurality of the concave portions are arranged and arranged in the fitting concave portion with each one end being a terminal portion and connected to the circuit board. A contact connection for the first conductive contact is arranged. In the second connector, for example, a fitting convex portion is provided, and the fitting convex portion is electrically connected to a plurality of cables or a flexible printed wiring board and arranged in a plurality. A contact connection for the second conductive contact is arranged. And the fitting convex part in the 2nd connector shall be inserted in the fitting concave part in the 1st connector, and when the fitting convex part is inserted in the fitting concave part, The contact connection portions of the plurality of second conductive contacts arranged are placed in a state of being pressed and contacted with the contact connection portions of the plurality of first conductive contacts arranged in the fitting recess.

  The fitting recess in the first connector is formed of an insulating material and is formed as a part of a housing that supports the plurality of first conductive contacts, and the fitting protrusion in the second connector is made of an insulating material. It is configured and formed as part of a housing that supports a plurality of second conductive contacts. And when the fitting convex part in the 2nd connector to which a plurality of cables or flexible printed wiring boards are connected is inserted into the fitting concave part in the 1st connector fixed to the circuit board, the second The connector housing is engaged with the housing of the first connector so that the first connector and the second connector are interengaged, and the plurality of first conductive contacts and the plurality of second conductive contacts Are placed in mutual contact connection. As a result, the plurality of cables or the flexible printed wiring board coupled to the second connector are electrically connected to the circuit board to which the first connector is fixed.

  In this way, a plurality of cables or flexible printed wiring boards are connected to electrically connect a plurality of cables or flexible printed wiring boards connected to the second connector to the circuit board to which the first connector is fixed. When the second connector housing is engaged with the first connector housing fixed to the circuit board and the first connector and the second connector are brought into mutual engagement, It is required that the housing of the second connector be stably maintained in engagement with the housing of the first connector. Therefore, in the prior art, the first and second connectors are included, and when the first connector and the second connector are engaged with each other, the housing of the second connector is moved to the first connector. There has been proposed an interengaging connector device provided with locking means for mechanically locking with respect to a connector housing (for example, see Patent Document 1 or Patent Document 2).

  The mutual engagement connector device disclosed in Patent Document 1 includes a first connector (board-side connector (102)) provided on a board with a housing (insulator (21)), and a housing (insulator (11)). And a second connector (plug-side connector (100)) having a movable operation member (pull bar (10)) rotatably attached to the housing. A protrusion (1) is provided on the outer surface of the inner wall portion of the housing of the first connector so as to protrude outward, and the outer surface of the outer wall portion of the housing of the second connector is Ribs (7) are provided as protruding outwards. Further, the movable operation member provided in the second connector is formed of a metal rod-like member, and has an arm part (10b) and a rotation shaft (10a) forming the tip of the arm part (10b) at each of both ends. The rotating shaft (10a) penetrates the outer wall portion of the housing of the second connector from the outside to the inside, and forms a locking portion (a part of the lock mechanism) for the first connector. ing.

  When the first connector and the second connector are brought into the mutually engaged state, the housing of the second connector has its outer wall-like portion arranged outside the inner wall-like portion of the housing of the first connector. In this manner, it is fitted to the housing of the first connector. At this time, the rotating shaft (10a) of the movable operation member provided in the second connector is engaged and locked with the protrusion (1) provided on the outer surface of the inner wall portion of the housing of the first connector. Thus, the housing of the second connector is mechanically locked to the housing of the first connector, thereby maintaining the mutual engagement of the first and second connectors.

  Thereafter, when the movable operation member provided in the second connector is rotated, the arm portion (10b) of the movable operation member is a rib (7) provided on the outer surface of the outer wall portion in the housing of the second connector. As a result, the movable operating member is elastically deformed, and the rotation shaft (10a) of the movable operating member is moved outward from the inner wall portion of the housing of the first connector. The engagement locking state with respect to the protrusion (1) provided on the outer surface of the inner wall-shaped portion in the housing is released. As a result, the housing of the second connector is released from mechanical locking to the housing of the first connector. After the rotating shaft (10a) of the movable operating member is released from the engagement locking state with the protrusion (1) provided on the housing of the first connector, the elastic member moves along with the further rotation of the movable operating member. The movable operating member that has undergone deformation returns to a state in which no elastic deformation has occurred.

  In addition, the mutual engagement connector device disclosed in Patent Document 2 includes a first connector (receptacle connector (200) having a housing (insulator (220)) and a metal member (shell (250)) covering most of the housing. )) And a second connector (plug connector (300)) having a housing (insulator (340)) and a movable operation member (pull bar (370)) rotatably attached to the housing. It is configured. The metal member provided in the first connector is provided with a lock portion (252) in which a locked hole (254) is formed. The movable operation member provided in the second connector is formed of a metal rod-like member, and is connected from the main portion (372) and the both ends of the main portion so as to bend and extend in a direction intersecting the main portion. There are a portion (376) and a held portion (374) which is further bent from the connecting portion (376) and extends in a direction parallel to the main portion. The held portion (374) penetrates the outer wall-like portion provided with the cam portion (348) on the inner surface side of the housing of the second connector from the inner side to the outer side, and the end portion thereof is the second portion. It is supposed that the outer wall-shaped portion of the housing of the connector can protrude outwardly, and forms a locking portion (375) for the first connector.

  When the first connector and the second connector are brought into the mutually engaged state, the housing of the second connector is formed with a locked hole (254) in the outer wall portion of the first connector. The lock portion (252) is fitted inside the housing of the first connector so as to be arranged inside the housing. At that time, the locking portion, which is the end of the held portion (374) in the movable operation member provided in the second connector, is locked into the locked hole (252) formed in the lock portion (252) in the first connector. 254) and mechanically locking the housing of the second connector with respect to the housing of the first connector so that the first and second connectors are in mutual engagement. Maintained.

  Thereafter, when the movable operation member provided in the second connector is rotated, the connecting portion (376) of the movable operation member is connected to the cam portion (on the inner surface side of the outer wall portion in the housing of the second connector). 348), and the movable operation member undergoes elastic deformation, whereby the engaging portion which is the end of the held portion (374) bent and extended from the connecting portion (376) The connector is moved to the inner side of the outer wall portion of the housing of the connector, and the engagement locking state with respect to the locked hole (254) formed in the lock portion (252) of the first connector is released. As a result, the housing of the second connector is released from mechanical locking to the housing of the first connector. After the locking portion (375) of the movable operation member releases the engagement locking state with respect to the locked hole (254) formed in the lock portion (252) of the first connector, further movement of the movable operation member is performed. With the rotation, the movable operation member that has undergone elastic deformation returns to a state in which no elastic deformation has occurred.

Japanese Patent Laying-Open No. 2005-267777 (paragraphs 0058 to 0069, FIGS. 1 to 5) JP 2009-170250 A (paragraphs 0018 to 0028, 0031, FIGS. 1 to 10)

  As described above, the first and second connectors, which are conventionally proposed, are configured, and when the first and second connectors are mutually engaged, one of them is mechanically engaged with the other. In the mutual engagement connector device provided with the locking means for stopping, the following disadvantages are observed in each of them.

  First, in the mutual engagement connector device shown in Patent Document 1, the first connector and the second connector are made of a metal rod-like member provided in the second connector in a state where the first connector and the second connector are mutually engaged. The rotating shaft that forms the locking portion of the movable operation member is engaged and locked with the protrusion provided on the housing of the first connector under a state where the movable operation member is not elastically deformed. The housing of the first connector is mechanically locked to the housing of the first connector, and the movable operation member is provided in the housing of the first connector under a state where the movable operation member is elastically deformed. The engagement locking state with respect to the protruding portion is released, and the housing of the second connector is released from the mechanical locking with respect to the housing of the first connector. Thus, the second connector housing is mechanically locked to the first connector housing and the second connector housing is released from mechanical locking to the first connector housing. When the second connector housing is mechanically locked to the first connector housing, the elastic deformation is once generated and then the elastic deformation is not generated. The rotating shaft that forms the locking portion of the movable operation member that has returned to the state is engaged and locked with the protrusion provided on the housing of the first connector.

  Therefore, once the elastic deformation has occurred, the rotating shaft that forms the locking portion of the movable operation member that has returned to the state in which no elastic deformation has occurred is engaged with the engaging portion of the protrusion provided on the housing of the first connector. When the movable operating member that has once undergone elastic deformation returns to the state in which it has not undergone elastic deformation when taking the stop state, the movable operating member does not return to its original state due to plastic deformation accompanying elastic deformation May be imitated. When such a situation is imitated, the position of the rotation shaft is displaced by plastic deformation of the movable operation member, and the engagement locking with the protrusion provided on the housing of the first connector by the rotation shaft is performed. Failure to do so will result in uncertain mechanical locking of the second connector housing to the first connector housing.

  Furthermore, in the mutual engagement connector device disclosed in Patent Document 1, the rotation shaft that forms the locking portion of the movable operation member passes through the outer wall portion of the housing of the second connector from the outside to the inside. While being supported by the housing of the second connector, it is assumed to be engaged and locked with the protrusions provided on the housing of the first connector. That is, the rotating shaft that forms the locking portion of the movable operation member does not engage with a metal member having great rigidity, and the second connector housing and the first connector are formed of an insulating material that is inferior in rigidity. By engaging with the housing, the second connector housing is mechanically locked to the first connector housing. Therefore, in particular, the first and second connectors can be reduced in size and weight, and the thicknesses of the first connector housing and the second connector housing can be reduced. The movable operation member is not firmly supported by the housing of the second connector of the rotation shaft, and the engagement of the movable operation member with the protrusion provided on the housing of the first connector by the rotation shaft is sufficient. There is a risk that it cannot be performed reliably and reliably.

  Moreover, in the mutual engagement connector apparatus shown by patent document 2, it consists of a metal rod-shaped member with which a 2nd connector is provided in the state which the 1st connector and the 2nd connector mutually engaged. The engaging portion, which is the end of the held portion of the movable operation member, engages with the locked hole formed in the lock portion of the first connector in a state where the movable operation member is not elastically deformed. The second connector housing is mechanically locked with respect to the first connector housing, and the movable operating member is elastically deformed in a state where the first connector housing is elastically deformed. The engagement locking state with respect to the locked hole formed in the locking portion of the connector is released, and the housing of the second connector is released from mechanical locking with respect to the housing of the first connector. Thus, the second connector housing is mechanically locked to the first connector housing and the second connector housing is released from mechanical locking to the first connector housing. When the second connector housing is mechanically locked to the first connector housing, the elastic deformation is once generated and then the elastic deformation is not generated. The locking portion which is the end portion of the held portion in the movable operation member that has returned to the state takes an engagement locking state with respect to the locked hole formed in the locking portion of the first connector.

  Therefore, after the elastic deformation once occurs, the locking portion which is the end of the held portion in the movable operation member that has returned to the state where no elastic deformation has occurred is formed on the lock portion formed in the lock portion of the first connector. When the movable operating member that has once undergone elastic deformation returns to the state that has not undergone elastic deformation when the engagement locking state with respect to the locking hole is taken, the movable operating member undergoes plastic deformation accompanying the elastic deformation, There is a risk that the situation will not be restored to this state. When such a situation is imitated, the position of the locking portion is displaced due to plastic deformation of the movable operation member, and the locked portion formed in the locking portion of the first connector by the locking portion is displaced. Engagement locking is not performed properly, and mechanical locking of the second connector housing to the first connector housing becomes uncertain.

  Further, in the mutual engagement connector device disclosed in Patent Document 2, the held portion of the movable operation member is located outside the outer wall-like portion provided with the cam portion on the inner surface side of the housing of the second connector from the inside to the outside. Under the condition that it is supported by the housing of the second connector, the engaging portion that is the end of the second connector is engaged with the locked hole formed in the locking portion of the first connector. It is supposed to be. In other words, the held portion having the end portion that forms the locking portion of the movable operation member does not engage with the metal member having a large rigidity, and the second connector formed of an insulating material that is inferior in rigidity. The housing of the second connector is mechanically locked to the housing of the first connector while being engaged with the housing. Therefore, in particular, the first and second connectors can be reduced in size and weight, and the thicknesses of the first connector housing and the second connector housing can be reduced. Is not firmly supported by the housing of the second connector of the held portion in the movable operation member, and is formed in the lock portion of the first connector by the locking portion which is the end of the held portion in the movable operation member. There is a risk that engagement and locking with respect to the locked hole cannot be reliably performed with sufficient reliability.

  In view of such a point, the invention described in the claims of the present application includes a first connector to be mounted on a circuit board and a second connector to which a cable or a wiring board is connected. A mechanism that allows the cable and the wiring board connected to the second connector to be electrically connected to the circuit board on which the first connector is mounted by mutually engaging the two connectors. The second connector housing is engaged with the first connector housing and the first connector and the second connector are engaged with each other. By the locking means arranged so as to be able to rotate and displace to the second connector, the locking of the first connector with respect to the housing of the first connector can be stably and firmly performed with sufficient reliability. To provide mutual engagement connector device that can.

The state in which the contact locking portion provided in the mating locking portion does not contact the planar portion of the movable locked portion is taken, and the engagement locking portion for the planar portion of the movable locked portion is used. The mechanical lock is released. As a result, the second housing is released from mechanical locking with respect to the first housing, and the second housing can be intentionally separated from the first housing.

  Under such circumstances, the holding metal member in the first connector includes, for example, a pair of engaging members disposed on the circuit board to which the first housing is fixed by the holding metal member and facing each other. An engagement locking portion is formed by the engagement members. And, for example, a contact locking portion that abuts a planar portion of the movable locked portion and mechanically locks it on one of a pair of engagement members forming the engagement locking portion.
