  By the way, in the connector, since the movable housing movable in the front-rear direction, the width direction, and the vertical direction with respect to the fixed housing is supported only by the elastically deformable terminals, when connecting to the mating terminal, the mating terminal The terminal is elastically deformed by the insertion pressure, and the contact of the terminal is displaced in the insertion direction of the mating terminal. For this reason, there is a problem that the insertion amount of the mating terminal with respect to the terminal becomes insufficient, and the connection reliability is lowered.

  Therefore, if a lock member that can restrict the movement of the movable housing relative to the fixed housing is provided, and the counterpart terminal is inserted while the movement of the movable housing is restricted by the lock member, a sufficient amount of insertion of the counterpart terminal relative to the terminal can be secured. can do. In this case, it is necessary to release the lock by operating the lock member after connecting the mating terminal, but for example, the connector is arranged in a narrow space between the boards, or other parts around When there is no space for operating the lock member around the connector, such as when they are arranged close to each other, there is a problem in that the lock of the lock member cannot be released.

  The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to connect the counterpart terminal in a state where the movement of the movable housing in the direction orthogonal to the substrate is restricted, and to externally An object of the present invention is to provide a connector that can release the movement restriction of the movable housing without being operated.

  In order to achieve the above object, the present invention provides a fixed housing fixed to a substrate, a movable housing provided movably with respect to the fixed housing, one end side held by the movable housing, and the other end side And a mating terminal of the mating connector is inserted and connected to one end of the terminal held by the movable housing from a direction orthogonal to the board, and the movable housing is connected to the stationary housing. In a connector that allows movement by elastic deformation of a terminal, the movable housing is engaged with the fixed housing so as to be movable only in a direction parallel to the substrate, and is engaged with a movable housing at a predetermined position in a direction parallel to the substrate. Restricts the movement of the movable housing in the direction perpendicular to the substrate, and other predetermined positions in the direction parallel to the substrate. A movable member that is movable in only the direction perpendicular to the substrate, and the counterpart connector is engaged with the counterpart connector. Position where the movement restriction is released from the position where the movement of the movable housing is restricted while moving relative to the movable housing in the direction orthogonal to the substrate by abutting from the insertion direction of the side terminal. And a second movable member that is moved up to.

  Thereby, when connecting with the counterpart terminal, the counterpart terminal is inserted in a state in which the movement of the movable housing in the direction orthogonal to the substrate is regulated by regulating the movement of the movable housing by the first movable member. Is possible. At that time, the second movable member moves relative to the movable housing in a direction perpendicular to the substrate by inserting the mating terminal into the movable housing while bringing the counterpart connector into contact with the second movable member. Then, since the first movable member moves to the position where the movement restriction of the movable housing is released by the second movable member, the movement restriction of the movable housing is automatically released without operating from the outside.

  According to the present invention, since the counterpart terminal can be inserted in a state where the movement of the movable housing in the direction orthogonal to the substrate is restricted, the terminal is not elastically deformed by the insertion pressure of the counterpart terminal. A sufficient amount of insertion of the mating terminal can be obtained, and connection reliability can be improved. Further, since the movement restriction of the movable housing can be automatically released without operating from the outside, it is extremely advantageous when there is no space for operating from the outside around the connector.

  The board connecting portion 55 extends from the lower end of the second fixing portion 53 and is formed to extend toward the front of the terminal 50.

  The connector configured as described above is disposed on the upper surface of the substrate 1 and is fixed to the substrate 1 by soldering the fixing members 15 of the fixing housing 10 and the substrate connecting portions 55 of the terminals 50 to the substrate 1. . In this case, the second movable member 40 is moved to a predetermined upper position. That is, when the second movable member 40 is moved upward, the contact portion 42a of the second movable member 40 contacts the rear end edge of the opening 31 of the first movable member 30 while moving upward, The first movable member 30 moves rearward. As a result, when the first movable member 30 moves rearward to a predetermined position, the engaging portion 32 is positioned between the upper engaging portion 23 and the lower engaging portion 24 of the movable housing 20, and the engaging portion 32 is located. The movement in the vertical direction is restricted by the upper engagement portion 23 and the lower engagement portion 24, and the movable housing 20 is locked.

  When connecting the mating connector 2 to the connector, the mating terminal 3 is inserted into the insertion port 22 of the movable housing 20 from above the substrate 1. At this time, when the mating terminal 3 is inserted into the movable housing 20, the mating terminal 3 is held between the contact portions 51a of the contact portions 51 while spreading the contact portions 51 of the terminals 50, and the contact portions 51a. Is brought into pressure contact with the mating terminal 3 so that the mating terminal 3 and the terminal 50 are connected. Further, when the mating terminal 3 is press-fitted between the contact portions 51, the movable housing 20 tries to move downward against the press-fitting, but as shown in FIG. Since the engaging portion 32 of the first movable member 30 is interposed between the lower engaging portion 24, the downward movement of the movable housing 20 is restricted by the first movable member 30. That is, when the movable housing 20 freely moves downward when the mating terminal 3 is press-fitted between the contact portions 51, the mating length of the mating terminal 3 (from the tip of the mating terminal 3 to the terminal 50). The amount of insertion up to the contact point) may be insufficient, but since the downward movement of the movable housing 20 is restricted by the first movable member 30, the terminal 50 is caused by the insertion pressure of the mating terminal 3. The fitting length of the mating terminal 3 is sufficiently ensured without elastic deformation. Even when the movement of the movable housing 20 in the vertical direction is restricted by the first movable member 30, the movable housing 20 can move in the front-rear direction and the width direction with respect to the fixed housing 10. The displacement of the mating terminal 3 in the front-rear direction or the width direction is absorbed by the movement of the first movable member 20 relative to the fixed housing 10 in the front-rear direction or the width direction.

  Further, when the mating terminal 3 continues to be inserted, the insulating member 4 of the mating connector 2 comes into contact with the upper surface of the first movable member 30, and the first movable member 30 is pressed downward by the mating connector 2. Moving. Thereby, the contact part 41a of the second movable member 40 contacts the front edge of the opening 31 of the first movable member 30 while moving downward, and the first movable member 30 moves forward. To do. As shown in FIG. 17, when the first movable member 30 moves to a predetermined position in the front, the engaging portion 32 of the first movable member 30 is disengaged from between the upper engaging portion 23 and the lower engaging portion 24. The restriction on the vertical movement of the engaging portion 32 by the upper and lower engaging portions 23 and 24 is released. As a result, the movable housing 20 can move in the vertical direction with respect to the fixed housing 10.

  Here, when the substrate 1 and the mating connector 2 are displaced from each other due to vibration or impact, the movable housing 20 is allowed to move due to the elastic deformation of the movable portion 54 of each terminal 50, and the mating connector with respect to the substrate 1. 2 misalignment is absorbed. At that time, since the movable housing 20 is restricted from moving in the front-rear direction and the width direction by the second movable member 40, the displacement in the front-rear direction and the width direction is the front-rear direction of the first movable member 30. And is absorbed only by movement in the width direction. Further, since the first movable member 30 is restricted from moving in the vertical direction by the engagement groove 14a of the fixed housing 10, the vertical displacement is caused only by the movement of the movable housing 20 in the vertical direction. Absorbed. Here, when the counterpart connector 2 is displaced in the front-rear direction, the movable housing 20 moves in the front-rear direction, and a rotational moment about the contact point between the terminal 50 and the counterpart terminal 3 is applied to the movable housing 20. However, since the first movable member 30 is restricted from moving in the vertical direction, the first movable member 30 moves in parallel in the front-rear direction along the substrate 1 without rotating with respect to the counterpart terminal 3, and the terminal 50 and the counterpart. The side terminals 3 do not slide (rotate) at the contact points.

  As described above, according to the present embodiment, the fixed housing 10 is movably engaged only in the direction parallel to the substrate 1 (the front-rear direction and the width direction) and is movable at a predetermined position in the direction parallel to the substrate 1. The movement of the movable housing 20 in a direction (vertical direction) orthogonal to the substrate 1 is restricted by engaging with the substrate 20, and a direction orthogonal to the substrate 1 by moving to another predetermined position in a direction parallel to the substrate 1. Since the first movable member 30 for releasing the movement restriction of the movable housing 20 to the other side is provided and the movement of the movable housing 20 is restricted by the first movable member 30 when connecting to the counterpart terminal 3, the substrate The counterpart terminal 3 can be inserted in a state where movement of the movable housing 20 in a direction orthogonal to 1 is restricted. Thereby, since the terminal 50 is not elastically deformed by the insertion pressure of the counterpart terminal 3, the fitting length (insertion amount) of the counterpart terminal 3 with respect to the terminal 50 can be sufficiently obtained, and the connection reliability is improved. Can be achieved.

  Further, the movable housing 20 is movably engaged only in a direction orthogonal to the substrate 1, and the counterpart connector 2 abuts from the insertion direction of the counterpart terminal 3 so that the movable housing 20 is orthogonal to the substrate 1. And a second movable member 40 that moves the first movable member 30 from a position where the movement of the movable housing 20 is restricted to a position where the movement restriction is released while relatively moving in the direction. By inserting the mating terminal 3 while bringing the side connector 2 into contact with the second movable member 40, the movement restriction of the movable housing 20 can be automatically released without operating from the outside, and around the connector This is extremely advantageous when there is no space for external operation.

  In this case, the second movable member 40 is provided with a contact portion 41 a that contacts the first movable member 30 while moving in a direction orthogonal to the substrate 1, and the contact portion 41 a is orthogonal to the substrate 1. Since the first movable member 30 is moved in a direction parallel to the substrate 1 by contact with the inclined contact portion 41a, the first movable member 30 in the direction orthogonal to the substrate 1 is formed. The rectilinear motion of the second movable member 40 can be converted into the rectilinear motion of the first movable member 30 in the direction parallel to the substrate 1, and the movable housing 20 is moved by the first and second movable members 30, 40. The deregulation operation can be performed reliably.

  Furthermore, since the first movable member 30 is configured to restrict only the movement of the movable housing 20 in the direction orthogonal to the substrate 1, the first movable member 30 is orthogonal to the substrate 1 of the movable housing 20. The first movable member 30 can be moved in a direction parallel to the substrate 1 with respect to the fixed housing 10 even in a state where movement in the direction to be regulated is restricted. Thereby, since the position shift in the direction parallel to the board | substrate 1 of the other party terminal 3 at the time of a connection can be absorbed, a connection operation | work can be performed easily.
