  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 flexible printed wiring boards connected to the second connector are electrically coupled 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 shown in Patent Document 1 includes a first connector (a mating connector (60)) having a housing (62) fixed to a circuit board, and a reception formed on the housing of the first connector. A second body having a housing (11) having a main body (12) fitted in the recess and a lock lever (13) forming a pair of elastic portions respectively provided at opposite end edges of the main body (12). Connector (connector (10)). A cable such as a flat cable (F) including a plurality of cables is connected to the second connector. Under such circumstances, the receiving recess in the housing of the first connector is provided with a pair of corresponding lock portions, and each of the pair of lock levers in the housing of the second connector has a push button portion. The formed pressed part (13D) and a lock claw (13C-1) as a lock part are provided.

  And when the main-body part in the housing of a 2nd connector fits into the receiving recessed part formed in the housing of a 1st connector, the lock nail | claw provided in each of a pair of lock lever in the housing of a 2nd connector Engages with a corresponding one of the pair of corresponding locking portions provided in the receiving recess in the housing of the first connector. Thereby, the housing of the second connector is mechanically locked to the housing of the first connector, and the housing of the second connector stably maintains the engaged state with the housing of the first connector. It is supposed to be.

  Thereafter, when releasing the housing of the second connector from the engaged state with the housing of the first connector, the pair of pressure-receiving portions respectively provided on the pair of lock levers in the housing of the second connector are simultaneously By pressing in the direction toward the housing of the second connector, an elastic displacement in the vicinity of the housing of the second connector is generated in each of the pair of lock levers. With each elastic displacement of the pair of lock levers, the lock claw provided on each lock lever disengages from the corresponding lock portion provided in the receiving recess in the housing of the first connector, and Separate from the corresponding lock. As a result, the housing of the second connector is released from the engaged state with the housing of the first connector. Then, for example, after the main body portion in the housing of the second connector is removed from the receiving recess formed in the housing of the first connector, each of the pair of lock levers in the housing of the second connector is provided. The pressure on the pair of pressed parts is stopped, and each of the pair of lock levers returns to its original position by its own elasticity.

  Moreover, the mutual engagement connector apparatus shown by patent document 2 is equipped with the housing (insulator (21)), the 1st connector (board | substrate side connector (102)) distribute | arranged to the board | substrate, and the housing (insulator (11 )) And a movable connector (pull bar (10)) rotatably attached to the housing. The second connector (plug-side connector (100)) is provided. A plurality of cables are connected to the cable fitting portion (12) in the second connector. Under such circumstances, the 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 wall shape of the housing of the second connector is also provided. A rib (7) is provided on the outer surface of the part so as to protrude outward. 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 in the mutually engaged state, the housing of the second connector has its outer wall-shaped portion arranged outside the inner wall-shaped portion of the housing of the first connector. In this manner, it is fitted into the housing of the first connector. At this time, the rotation shaft of the movable operation member provided in the second connector is engaged and locked with the protrusion provided on the outer surface of the inner wall portion of the housing of the first connector, and the second connector Are mechanically locked to the housing of the first connector, thereby maintaining the mutual engagement of the first and second connectors.

  As described above, the first and second connectors that have been proposed in the prior art are configured, and when the first and second connectors are engaged with each other, one of them is mechanically locked with respect to the other. In the mutual engagement connector device provided with the locking means, the following inconveniences are observed in each of the first and second connectors.

  First, in the mutual engagement connector device disclosed in Patent Document 1, the main body portion of the second connector housing is fitted into the receiving recess formed in the first connector housing, and the second connector housing The lock claw provided on each of the pair of lock levers in the housing engages with the corresponding one of the pair of corresponding lock portions provided in the receiving recesses in the housing of the first connector, and the second connector For example, in order to disengage the housing of the second connector from the housing of the first connector, the housing of the second connector is moved to the first connector with the first housing being mechanically locked to the housing of the first connector. When releasing the connector from the engaged state with the housing of the second connector, the pair of lock levers in the housing of the second connector are A pair of pressed portion provided, is required operation to be pressed in a direction towards the at the same time the second connector housing. In other words, the second connector must be applied to the pair of pressure-receiving portions provided on the pair of lock levers in the housing of the second connector, respectively, by pressing them simultaneously in the direction toward the housing of the second connector. The housing cannot be released from the engaged state with the housing of the first connector.

  In such a case, the operation of simultaneously pressing the pair of pressure-receiving portions provided in the housing of the second connector in the direction toward the housing of the second connector is fixed to the circuit board together with other electronic components and the like. Since the second connector housing is mechanically locked to the connector housing, the operation is extremely difficult and troublesome due to the influence of other electronic components. . Therefore, each time the second connector housing mechanically locked to the first connector housing is detached from the first connector housing, the second connector housing is provided in the second connector housing. An extremely difficult and troublesome operation must be performed on the pair of pressed parts.

  Furthermore, in the mutual engagement connector device disclosed in Patent Document 1, an operation of simultaneously pressing a pair of pressure-receiving portions provided on the second connector housing in the direction toward the second connector housing is performed on the circuit board. The second connector housing mechanically locked to the first connector housing fixed together with other electronic components etc. is, for example, a thumb and an index finger from the opposite end edge side of the main body. For this reason, on the circuit board to which the housing of the first connector is fixed, each of the opposing edge portions of the main body portion of the housing of the first connector is used. On the outside, a relatively large space for inserting two fingers is required. As a result, the effective use space on the circuit board to which the housing of the first connector is fixed is reduced.

  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 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 2, 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, and is second. Under the condition that it is supported by the housing of the connector, it is assumed that it is engaged and locked with the protrusion 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.

  In view of such a point, the invention described in the claims of the present application includes a first connector attached to 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. The locking means provided on the first connector and the locked means disposed so as to be displaceable on the second connector are used to lock and lock the first connector housing with respect to the first connector housing. Solution A circuit to reduce the effective use space on the substrate with a simple and easy operation to be performed without providing interengaging connector device can be stably and reliably on the basis of sufficient reliability.

At this time, the locked portion takes a position locked by the engaging locking portion. Accordingly, the housing of the second connector partially covered by the shell member to which the cover member is movably attached is mechanically connected to the housing of the first connector fixed to the circuit board by the holding metal member. It is put in the state locked to.

  The engagement locking portion is provided, for example, so as to be elastically displaceable. When the second housing is engaged with the first housing, the engagement locking portion is elastically displaced. By engaging with the locked portion, the locked portion can be locked.

  After that, the engagement locking portion of the holding metal fitting provided in the first connector engages with the locked portion of the cover member provided in the second connector to lock the locked portion. In this case, when the cover member is moved with respect to the shell member in a predetermined direction intersecting the arrangement direction of the plurality of second contacts, for example, in a direction orthogonal to the arrangement direction of the plurality of second contacts. Along with this, the locked portion of the cover member moves in the above-described predetermined direction, and takes a position released from the locking by the engaging locking portion of the holding metal member. Accordingly, the housing of the second connector partially covered by the shell member to which the cover member is movably attached is released from the locking of the first connector fixed to the circuit board by the holding metal member.
