Hereinafter, preferred embodiments of the present invention will be shown.
The lock arm has a locking portion disposed so as to be able to come into contact with the mating lock portion when the two housings are properly fitted, and the detection member is locked to the locking portion at the standby position. The movement restricting portion for restricting the movement to the detection position is provided, and the movement restricting portion and the stop portion are arranged coaxially in the fitting direction of both housings. Since the movement restricting portion and the stopper portion are arranged coaxially in the fitting direction of both housings, it is possible to avoid the connector from becoming large in a direction crossing the fitting direction.

  The lock arm is provided with a pair of over-deflection restricting portions that restrict over-deflection of the lock arm by abutting against opposing surfaces in the bend direction when the lock arm attempts to bend and deform excessively. The retaining portion is provided in a bridge portion that spans between the pair of excessive deflection restricting portions. According to this, the excessive deflection of the lock arm is regulated by the pair of excessive deflection regulating portions. On the other hand, when an excessive load is applied to the excessive deflection regulating portion, the excessive deflection regulating portion may be deformed. However, according to this configuration, since the bridge portion is bridged between the two excessive deflection regulating portions, the excessive deflection regulating portion is reinforced, thereby preventing the excessive deflection regulating portion from being deformed by an excessive load. can do. Moreover, since the retaining portion is formed in the bridge portion, and the reliability improving function for preventing excessive bending and the retaining function are integrated in the bridge portion, the connector can be further reduced in size and the structure can be simplified. Can be achieved.

  The bridge portion is bent and deformed by interfering with the stopper portion in the process from when the detection member is assembled to the housing to the standby position. Thus, the detection member can be smoothly brought to the standby position by accompanying the bending operation of the bridge portion.

  The bridge portion includes an interfered portion, and the detection member includes an interference portion that restricts movement of the bridge portion to the detected position by interfering with the interfered portion at the standby position. Since the movement of the detection member to the detection position is restricted by the interference part interfering with the interfered part of the bridge part, the movement restriction function is further added to the bridge part, and the configuration can be further simplified. .

As shown in FIG. 12, a recess 69 opened rearward is provided at the lower part of the second detection unit 62, and the interference unit 68 is provided across the recess 69, and both interference units 68 are provided. Is divided on both sides of the recess 69.

  As shown in FIG. 4, the third detection unit 63 can be bent together with the first detection unit 61. As shown in FIGS. 3, 4, and 12, a claw-like movement restricting portion 70 is provided at the front end portion of the third detecting portion 63 so as to protrude downward. As shown in FIG. 3, the movement restricting portion 70 is disposed so as to be able to be locked to the rear surface of the locking portion 27 in the standby position until both housings 10 and 100 are properly fitted. As described above, after the two housings 10 and 100 are properly fitted, they are disposed on the front surface of the locking portion 27 at the detection position so as to be locked. And the movement control part 70 is arrange | positioned coaxially with the stop part 67 in front of the stop part 67 (refer FIG. 11).

  As shown in FIG. 1, the surrounding portion 64 is configured to be slightly larger than the slide mounting portion 28 of the lock arm 22 and is assembled by being externally fitted to the slide mounting portion 28. A substantially prismatic stopper 71 is provided between the rear end portion of the surrounding portion 64 and the first detection portion 61 (see FIG. 11). The stopper 71 can be fitted into the concave groove 31 at the detection position.

Next, the operation of the connector of this embodiment will be described.
The detection member 60 is assembled to the slide mounting portion 28 of the lock arm 22 from behind. At the time of assembly, the first detection unit 61 is inserted into the mounting hole 29 of the slide mounting unit 28, the third detection unit 63 is inserted into the communication groove 30 of the slide mounting unit 28, and the second detection unit 26 is inserted into the locking hole 26 of the arm body 23. The detecting portion 62 is inserted, and the surrounding portion 64 is fitted outside the slide mounting portion 28 (see FIG. 1). In this state, the rear surface of the surrounding portion 64 is pressed to move the detecting member 60 forward (to the standby position side). Slide. As shown in FIG. 2, in the process in which the detection member 60 moves to the standby position, the stop portion 67 slides on the upper surface of the bridge body 36, and the bridge portion 35 is bent and deformed downward. In addition, both side walls 72 of the surrounding part 64 are sandwiched between the both side walls 41 of the slide mounting part 28 and the two protective walls 16 (see FIG. 7), and both ends in the width direction of the lower surface of the surrounding part 64 are the support pieces 21. Slide the upper end (see FIG. 1).

  When the detection member 60 reaches the standby position, the bridge portion 35 is elastically restored, and accordingly, the stopper portion 67 is disposed on the front surface of the stopper portion 38 (see FIG. 3). Further, as shown in FIG. 7, in the standby position, both the second stoppers 65 are disposed so as to be able to be locked to the front surfaces of both the second retaining parts 32. For this reason, when the detection member 60 at the standby position is pulled rearward, both the second stoppers 65 are locked to the second stoppers 32 at both ends in the width direction of the detection member 60, and the center in the width direction of the detection member 60. At this point, the stopper 67 is locked to the stopper 38, and the detection member 60 is reliably prevented from coming out backward. Further, at the standby position, the movement restricting portion 70 is disposed so as to be able to be engaged with the rear surface of the engaging portion 27, and both the interference portions 68 are disposed so as to be able to interfere with both the interfered portions 39 (see FIG. 3). . For this reason, when the detection member 60 at the standby position is pushed forward, the movement restricting portion 70 is locked to the locking portion 27, the both interference portions 68 interfere with both the interfered portions 39, and the detection member 60 is moved forward. Moving to (detection position side) is reliably prevented. Thus, the detection member 60 is held in a state where movement in the front-rear direction is restricted to the standby position. When the detection member 60 is assembled to the lock arm 22, the stop portion 67 and both interference portions 68 are disposed at a position facing the bending space 25 of the lock arm 22, and are disposed within the entire width of the arm body 23 in the width direction. .

  Subsequently, both housings 10 and 100 are fitted. In the process of fitting the two housings 10, 100, the mating lock portion 111 of the mating housing 100 interferes with the locking portion 27 of the lock arm 22, and the lock arm 22 is bent and deformed in the direction in which the front end of the arm body 23 is lifted. . Thereafter, as shown in FIG. 4, when the two housings 10 and 100 are properly fitted, the lock arm 22 is elastically restored, and the mating lock portion 111 is fitted into the locking hole 26 and the movement is restricted. The part 70 is pushed and pushed up. Then, the third detection unit 63 is bent upward together with the first detection unit 61, and the movement restricting unit 70 is dissociated from the locking unit 27. At this time, since the engagement portion of the interference portion 68 with respect to the interfered portion 39 is very small, the movement of the detection member 60 to the detection position is substantially allowed.

  Next, the detection member 60 is pushed forward (detection position side). Then, the interference state of the interference part 68 with respect to the interfered part 39 is released, and the detection member 60 is moved toward the detection position. During this time, the movement restricting portion 70 slides on the upper surfaces of the counterpart lock portion 111 and the locking portion 27, and the bent state of the first detecting portion 61 and the second detecting portion 62 is maintained. As shown in FIG. 5, when the detection member 60 reaches the detection position, the first detection unit 61 and the second detection unit 62 return elastically, and the movement restricting unit 70 can be locked to the front surface of the locking unit 27. Placed in. As a result, the movement of the detection member 60 in the direction of returning to the rear (standby position side) is restricted. Further, at the detection position, the stopper 71 of the surrounding portion 64 is disposed so as to be fitted into the concave groove 31 and can be stopped against the front end of the concave groove 31, and further forward movement of the detection member 60 is restricted. Thus, the detection member 60 is held in a state where movement in the front-rear direction is restricted to the detection position.

  On the other hand, when the housings 10 and 100 are kept in a semi-fitted state where they are not normally fitted, the movement restricting portion 70 does not dissociate from the locking portion 27, and thus the detection member 60 may be brought to the detection position. Can not. Therefore, when the detection member 60 reaches the detection position, it can be determined that the two housings 10 and 100 are in a properly fitted state.

  Further, if an excessive pushing force is applied to the rear end portion of the lock arm 22 in a state before the detection member 60 is assembled to the lock arm 22, both wing portions 24 are twisted and deformed, and the lock arm 22 is deformed. There is a risk that the lock function due to. However, in the case of the present embodiment, when the rear end portion of the lock arm 22 is forcibly pushed down by the external pressure, the excessive deflection regulating surfaces 34 of the two excessive deflection regulating portions 33 abut against the upper surface of the housing body 11, and the lock arm 22 22 or more bending operations are regulated. For this reason, the lock arm 22 is prevented from being excessively bent and deformed, and a predetermined lock function by the lock arm 22 can be achieved. Furthermore, since the bridge portion 35 is bridged between the two excessive deflection regulating portions 33, the deformation of both the excessive deflection regulating portions 33 themselves can be suppressed, and the reliability of the excessive deflection preventing function is improved.

  As described above, according to the present embodiment, the stop portion 67 of the detection member 60 in the standby position is disposed at a position facing the bending space 25 of the lock arm 22, and the retaining portion 38 is a bending space of the lock arm 22. Since the space of the bending space 25 of the lock arm 22 is effectively utilized and the retaining portion 38 and the retaining portion 67 are disposed on both sides of the lock arm 22. The connector can be made small.

  In addition to the stopper 67 and the stopper 38, a second stopper mechanism including the second stopper 65 and the second stopper 32 is provided, so that the reliability of the stopper function of the detection member 60 is improved. Is increased. And since the movement control part 70 and the stop part 67 of the detection member 60 are arrange | positioned along with the coaxial in the front-back direction, it can avoid that a connector becomes large in the width direction.

  Further, since the retaining portion 38 is provided in the bridge portion 35 spanned between the two excessive deflection regulating portions 33, the bridge portion 35 is integrated with the reliability improving function for preventing excessive deflection and the retaining function. Can be further reduced in size, and the configuration can be simplified. Furthermore, since the bridge part 35 has the interfered part 39 and the interference part 68 of the detection member 60 interferes with the interfered part 39 in the standby position, the movement of the detection member 60 to the detection position is restricted. Since the bridge part 35 is also provided with a movement restriction function, the configuration can be further simplified.

  Furthermore, in the process from when the detection member 60 is assembled to the housing 10 to the standby position, the bridge portion 35 interferes with the stop portion 67 and is bent and deformed, so that the detection member 60 is smoothly brought to the standby position. be able to.
