Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electrical connector for stably and reliably connecting a thin connecting conductor such as a flat cable to another circuit.

PRIOR ART

Conventionally, as this type of electrical connector, there is a connector as shown in FIGS. 4 to 7 disclosed in Japanese Utility Model Application Publication No. 57-7186, for example.

[Problem that the invention attempts to solve]

However, in the connector shown in FIGS. 4 to 7 of the above-mentioned Japanese Utility Model Publication No. 57-7186, both or one of the pair of contact portions connected to the contact pins is
Narrowed by the inner wall of the guide hole of the movable mold,
Since the connection is made by elastically pressing the connection wire inserted inside the contact portion from the left and right sides, all of the reaction force is received by the movable mold and the fixed mold.

As a result, the movable mold and the fixed mold, especially the side walls that receive the reaction force, gradually swell outward due to heat during use, causing a problem in which the contact pressure at the contact portion of the contact pin gradually decreases. It is thought that there are points.

[Means for solving problems]

In order to solve these conventional problems, the applicant previously proposed the device disclosed in Japanese Utility Model Application Publication No. 61-56782, but the present invention further improves this device and improves the slider and the housing. The purpose of this design is to provide a device that can maintain appropriate contact pressure over a long period of time by having the terminal itself receive the reaction force from the terminal.
The gist thereof is to include an electrical connection terminal consisting of a first arm part, a second arm part, and a regulating part each extending upward from a base; The electrical connection terminal is made up of a housing body that accommodates the electrical connection terminals so as to be freely movable, and a housing lid body that includes a slider that fits into the housing body and is inserted between the second arm part and the regulating part. The first arm part and the second arm part of
A conductor is sandwiched between the opposing portions of the arm portions to form a contact surface for electrical connection, and the upper end portion of the second arm portion is bent to the side opposite to the contact surface side. The electrical connector is characterized in that the slider inserted between the first arm and the second arm presses the second arm toward the contact surface.
