Problems solved by technology

This makes it difficult to insert the flat conductor during use. In addition, if the above-mentioned gap becomes smaller and exceeds the allowable value, the front end of the flat conductor collides with the rear end of the pressing arm portion toward the front to give it an impact force.
The impact force acts in the direction of the long side of the pressing arm, so the pressing arm may be bent, which greatly hinders the connection between the flat conductor and the connector.

[0059] Next, according to Figure 5 ~ Figure 7 , the second embodiment of the present invention will be described. In the previous embodiment, the terminal 10 has a shape maintaining the flat surface of the metal plate as a whole, but in this embodiment, the restricted portion is formed by bending along the plate thickness direction. exist Figure 5 ~ Figure 7 Among them, only the restricted part of the terminal 10 and the restricted part of the housing 30 and the Figure 1 to Figure 4 The previous embodiment shown is different, and other parts are the same, so in Figure 5 ~ Figure 7 in, for Figure 1 to Figure 4 Common parts are given the same reference numerals, and description thereof will be omitted.

[0063] Next, according to Figure 8 , the third embodiment of the present invention will be described. Figure 8 (A), (B), (C) in and Figure 4 (A), (B), and (C) in the corresponding states are shown. This embodiment is characterized in that the portion to be regulated is not provided at the rear end of the terminal but is provided at the middle position in the front-rear direction. Figure 1 to Figure 4 The same applies to the first embodiment shown. Therefore, even in the present embodiment, the terminal has a shape maintaining the flat surface of the metal plate. Figure 8 in, right with Figure 4 Common parts are given the same reference numerals, and description thereof will be omitted.

[0064] exist Figure 8 In the present embodiment shown in (A), in the terminal 10, there is a pressing portion 11B-4 at the rear end of the pressing arm portion 11, and there is no pressing portion 11B-4 behind it. Figure 4 In (A) as the rear end protrusion of the restricted port...

Abstract

The invention provides an electrical connector for a flat conductor. The electrical connector includes a terminal (10) made of a metallic plate, a housing (30), and a movable part (40); the terminal has a pressing arm part (11) extending such that an insertion-and-removal direction of a flat conductor is in a longitudinal direction, and a supporting arm part (12) extending in the longitudinal direction, which is connected with the pressing arm part by a connecting part. The pressing arm part has a pressing part (11B-3) for pressing one surface of the flat conductor on a rear end side which is an insertion side of the flat conductor, and a pressure receiving part (11A-1) receiving a force from a cam part on a position more forward than the pressing part. The pressing arm part generates elastic displacement in a surface identical to a plate surface of the terminal while the pressure receiving part receives a force form the cam part, the pressing portion presses the flat conductor, and elastic displacement limiting mechanisms (11B-2, 31B) for limiting the pressing arm part and more backward than the connecting part are arranged on the pressing arm portion and the housing of the terminal.

Description

technical field [0001] The present invention relates to an electrical connector for flat conductors. Background technique [0002] As the flat conductor, there are flexible substrates (FPC), flat cables, and the like. The above-mentioned flat conductors are often connected to electrical connectors mounted on circuit boards. As an electrical connector for a flat conductor to which the above-mentioned flat conductor is connected, for example, a connector disclosed in Patent Document 1 is known. [0003] In the connector of Patent Document 1, a plurality of terminals made of a metal plate are arranged at intervals in a direction perpendicular to the plate thickness while maintaining the flat surface of the metal plate, and are held by the housing. In this patent document 1, two types of terminals are mixed and arranged. Both terminals have an upper pressing arm portion and a lower supporting arm portion substantially parallel to each other, and the two arm portions are connec...
