Problems solved by technology

However, since the front end portion of the lock arm constitutes an elastically deformable support point, if the through hole is opened, the elastic force of the lock arm decreases.
Therefore, with the configuration described above, the lock arm tends to lack reliability in terms of strength.

[0100] combine Figure 1 to Figure 20 A specific embodiment of the present invention is described. The connector A according to this embodiment includes a housing 10 and a mating housing 50 connectable to each other and a detection member 70 mounted on or in the housing 10 . Note that, in the following description, the side to be connected of the two housings 10 , 50 is referred to as the front side in terms of the front-rear direction FBD.

[0101] The fitting housing 50 is made of, for example, synthetic resin, and includes such as Figure 11 A forwardly open (in particular, substantially cylindrical) base 51 is shown in FIG. The lock receiving portion 52 is formed in or on the base 51 (specifically, the outer wall or the front end portion of the upper wall of the base 51 ). The lock receiving portion 52 penetrates through the base 51 (specifically, the upper wall) in the height direction HD (the direction intersecting the connection direction CD of the two housings 10 , ...

[0153] Next, refer to Figures 21 to 27 A second specific embodiment of the present invention is described. In the connector B of this second embodiment, the configuration of the detection member 100 is partly different from the configuration of the detection member 70 of the first embodiment described above. Since other components are substantially the same or similar to those in the first embodiment, the same or similar components are denoted by the same reference numerals, and their structures, functions, and effects are not described.

[0154] as in Figure 24 to Figure 27 As shown in , a protrusion 102 (specifically in the form of a substantially rectangular block) is formed upward or outward on or near the front or distal end portion of the elastic arm portion 101 forming part of the detection member 100, for example, made of synthetic resin. Protrusion, the shape of the protrusion 102 is partly different from the protrusion 87 of the first embodiment. An auxiliary pr...

[0167] Next, refer to Figure 28 A third specific embodiment of the present invention will be described. In the connector C of this third embodiment, the configuration of the auxiliary recess 35 is partly different from the auxiliary recess 32 formed on the inner upper surface of the receiving recess 31 of the lock arm 12 in the connector B of the second embodiment described above. structure. Since other components are substantially the same or similar to those in the first embodiment, the same or similar components are denoted by the same reference numerals, and their structures, functions, and effects are not described again.

[0168] The rear end portion of the receiving recess 35 of the third embodiment is chamfered to form at least one escape portion 36 opened inwardly or downwardly and rearwardly. By forming the escape portion 36 , the interference of the auxiliary protrusion 103 with the rear end portion of the lower surface of the locking protrusion 24 during the sli...

Abstract

An object of the present invention is to improve locking reliability. A lock arm 12 extends backward in a cantilever manner from a front end part of a housing main body 11. The lock arm 12 includes an accommodating recess 31 which is open toward a deformation space 25 therefor and toward the back. When the housing main body 11 is properly connected to a mating housing 50 and a detecting member 70 is pushed from a standby position to a detection position, a part of the detecting member 70 is inserted into the accommodating recess 31.

Description

technical field [0001] The invention relates to a connector, a connector assembly and an assembly method thereof. Background technique [0002] A connector disclosed in Japanese Unexamined Patent Publication No. 2004-103551 includes: a mating housing having a locking receiving portion; a housing main body connectable to the mating housing; a locking arm that cantilever from the housing; the front end of the main body extends backward and is configured to hold the housing main body and the mating main body in a connected state by elastically engaging with the lock receiving portion; and a detection member to be mounted on the housing main body, Can be moved from the initial position to the detection position via the standby position and configured to detect whether the mating housing has been properly connected to the housing body based on whether the detection member can be moved from the standby position to the detection position. [0003] The locking portion is formed to ...
