Connector
A connector and retainer technology, which is applied in the direction of connection, parts of connecting devices, devices for connecting/disconnecting connecting parts, etc., can solve the problem of reducing the holding force of the front retainer, locking the support part and the locking part. Reduced range and inability to secure the locking support part, etc., achieve the effect of reducing the height and preventing the reduction of the locking range

Problems solved by technology
[0008] However, in the case of the above-mentioned structure, when the wall is omitted from the front end upper part of the cavity, the height dimension of the partition wall becomes small, therefore, correspondingly, there is a formation area that cannot ensure the locking support portion and the locking support portion and the locking support portion are separated from each other. Possibility that the locking range of the part is reduced and the holding force against the front retainer is reduced

Embodiment 1
[0029] pass Figure 1 to Figure 13 Example 1 of the present invention will be described. The connector according to this embodiment has a housing 10 , a front holder 40 , and a terminal fitting 90 , and is capable of fitting with a mating connector not shown. In addition, in the following description, regarding the front-rear direction, the side of the mating surface facing the mating connector is referred to as the front.
[0030] Such as Figure 4 As shown, the terminal fitting 90 is formed by bending a conductive metal plate, and has: a cylindrical box portion 91; The core wire portion exposed at the end portion of the electric wire 80 is crimp-connected, and is crimp-connected with the rubber plug 70 fitted to the end portion of the electric wire 80 . In the box portion 91 , an unillustrated convex portion hole into which a convex portion 19 described later is opened is formed. In addition, an elastic contact piece 95 is formed inside the box portion 91 (refer to Fig...

The present invention provides a connector capable of reducing the height of a housing and improving retention reliability with respect to a front holder. At the opening edge portion of the tab insertion hole (45) in the front surface of the front wall portion (41) of the front retainer (40), the retainer side where the tab (101) of the counterpart terminal fitting (100) is introduced is introduced The surface (47) is expanded and formed to cover the front side of the convex portion (19). At the opening edge portion of the cavity (18) in the front surface of the casing (10), the casing-side introduction surface (33) that introduces the tab is expandedly formed on the facing side except for the position opposite to the side portion. Where the tabs are inserted into the inside of the holes. A locking support portion for preventing the retainer from falling off is formed on a partition wall (23) between adjacent cavities in the casing. The locking support portion is located behind the case-side introduction surface, and has a portion overlapping the retainer-side introduction surface in the height direction of the partition wall.
Description
technical field [0001] The invention relates to a connector. Background technique [0002] The connector disclosed in Patent Document 1 has: a housing having a plurality of cavities; and a front retainer assembled in the housing and having a protruding piece that covers the front surface of the housing and penetrates at positions opposite to the cavities. Insert into the front wall of the hole. A bendable protrusion is formed on the inner surface of each cavity protruding forward. On the front retainer, anti-dropping portions are formed protruding rearward at positions corresponding to the respective cavities. The terminal fittings correctly inserted into each cavity are prevented from falling out of the cavity by the convex part in the first stage, and then with the correct assembly of the front retainer, the anti-loosening part enters the bending space of the convex part, thereby performing the second stage of anti-loosening . [0003] In addition, at the opening edge ...
