Problems solved by technology

Therefore, it is difficult to insert the pushing member 10b between the locking rod members 8b.
In addition, in this structure, when the connection terminal 2b is strongly pulled in the pulling-off direction, the locking of the connection terminal 2b may come off depending on the degree of deflection of the locking lever member 8b.
[0010] In addition, if the electrical connector described in Patent Document 2 is also downsized, the operating lever 1036 will also become smaller, so it becomes difficult for the operator to hold the operating lever 1036 to slide the receptacle locking tool 104A.
[0011] In addition, in the electrical connector described in Patent Document 3, when a tool is inserted into the holder, the male-side terminal fitting 111 and the fitting recess 1112 of the outer housing 1110 may be damaged.

Embodiment approach 1

[0058] according to Figure 1 to Figure 18 The electrical connector 10 according to Embodiment 1 of the present invention will be described. In addition, expressions such as "front" and "rear" in the following description refer to the side inserted into the electrical connector to be mated as "front" and the opposite side as "rear". .

[0059] figure 1 and Figure 2A , Figure 2B The illustrated electrical connector 10 is a waterproof electrical connector. The electrical connector 10 includes a connector terminal 20 , a housing 30 and a holder 40 .

[0060] Such as Figure 7 ~ Figure 10 As shown, the connector terminal 20 is a male type terminal. The connector terminal 20 includes a tab portion (Japanese: tab portion) 21 , a barrel portion 22 , a step portion 23 , a wire barrel portion 24 and an insulating barrel portion 25 . in addition, Figure 7 and Figure 9 express Figure 2B section at the same location. but, Figure 7 Indicates that the holder 40 is locate...

Embodiment approach 2

[0117] An electrical connector according to Embodiment 2 of the present invention will be described with reference to the drawings. In addition, in Figure 19 ~ Figure 22 in, right with Figure 6 , Figure 11 as well as Figure 12 Identical structures are assigned the same reference symbols.

[0118] In the holder according to Embodiment 2, both ends of the guide portion in the sliding direction or in a direction perpendicular to the sliding direction are formed asymmetrically.

[0119] exist Figure 19 and Figure 20 The holder 41 is shown along the Figure 21 and Figure 22 The insertion direction F4 of the operation rod 511 of the illustrated operation tool 51 is formed with an operation hole 417 and a guide portion 423 .

[0120] The operation hole 417 is formed such that a part of the end portion of one side S1 of the rectangular hole expands the width of the rectangular hole when viewed from the insertion direction F4. The guide portion 423 is formed continuousl...

Abstract

The invention provides an electrical connector. The electrical connector (10) includes a connector terminal (20), a housing (30) formed with a slider groove (314), and a retainer (40) locking the connector terminal and preventing the connector terminal (20) from being released by sliding from the unlocking position to the locking position. The retainer (40) includes a basal end (410) housed in the slider groove (314), and a projection (420) projecting from the basal end (410) toward the opening of an engagement hole (321). The basal end (410) is formed with an operation hole (415) in which an operating jig that changes the position of the retainer between the locking position and the unlocking position is inserted. The projection (420) is formed with a guide portion that guides the insertion of the operating jig in the operation hole (415).

Description

technical field [0001] The present invention relates to an electrical connector having a retainer for preventing connector terminals from coming off. Background technique [0002] Connector terminals are accommodated in terminal accommodation chambers formed in the case. The connector terminal is restrained from coming off by engaging with the lance-shaped portion formed in the terminal accommodating chamber. However, the miniaturization of electrical connectors is progressing, and there is a tendency that the holding force of the connector terminals will be insufficient only by relying on the lances. Therefore, an electrical connector has been developed in which a holder is provided on the housing in addition to the lance to double-lock the connector terminals. [0003] Electrical connectors that double lock connector terminals are described in, for example, Japanese Patent Application Laid-Open No. 62-64076 (hereinafter referred to as Patent Document 1), Japanese Patent ...
