Embodiment Construction

[0031] based on Figure 1 to Figure 17 The embodiments illustrated in the present invention are illustrated in detail.

[0032] figure 1 is the plan view of the connection terminal used, figure 2 It is a partially cutaway longitudinal section, image 3 is along figure 2 A cross-sectional view of line A-A. On the front part of the connection terminal 11 formed by punching and bending a conductive metal plate, a cylindrical connection part 12 is provided as a base part into which the mating-side insertion terminal is embedded, and the wire 15 is connected by a press-fit part 14 at the rear part passing through the middle part 13 . In addition, a cutout 16 is formed at the bottom of the connecting portion 12 .

[0033] Figure 4 is a perspective view of a casing 21 made of synthetic resin, Figure 5 is a longitudinal section view, Image 6 It is a bottom view, and two casings 21 are used in this embodiment. The housing 21 can accommodate, for example, six connection ...

Abstract

An electric connector capable of fixing even a small connection terminal by large locking force. Two housings (21) having a plurality of connection terminals (11) fixed are placed vertically symmetrically with their open surfaces facing each other, and a holder (31) having a lock (33) is interposed between the open surfaces of the housings (21). Further, an assembly of the housings (21) and the holder (31) is accommodated in an outer cover (41), and a bottom cover (42) is fixed to the bottom of the outer cover (41). Thus, the connection terminals (11) are rigidly prevented from moving backward and vertically by the housings (21) and the holder (31) and from moving forward by a front wall (44) of the outer cover (41).

Description

technical field [0001] The present invention relates to an electrical connector for accommodating small-sized connection terminals. Background technique [0002] For example, the size of connection terminals used for connecting electric circuits of automobiles and the like is gradually reduced due to weight reduction of automobiles. [0003] Generally speaking, in the housing of the electrical connector, the fastening of the received connecting terminals is realized by a flexible fastening lance provided in the housing. [0004] However, when the connecting terminal is extremely miniaturized, it is very difficult to form the clamping lance in the housing by injection molding, and even if it is formed, the clamping force will be weak due to its small size. [0005] To solve this problem, install the Figure 18 In the shown rear bracket 1 , fastening lances 2 are attached to each connection terminal on the rear bracket 1 , as shown in Patent Document 1, for example. [0006]...
