Embodiment Construction

[0035] In order to facilitate a better understanding of the purpose, structure, features, and effects of the present invention, the present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0036] Such as Figure 1 to Figure 3 As shown, the electrical connector 100 of the present invention is welded on a first device. In this embodiment, the first device is a circuit board A, and the circuit board A is provided with three through holes A1. The electrical connector 100 includes a body 1 extending lengthwise, two ear buckles 2 assembled at both ends of the body 1 , a plurality of conductive terminals 3 provided on the body 1 and three terminals installed at the bottom of the body 1 . A holder 4. The holder 4 can be held by a second device, and the second device can be the body 1 containing the conductive terminals 3 , or other electrical components or non-electrical components. In other embodiments, the electrical...

Abstract

The invention discloses an electrical connector installed on a circuit board with a through hole, comprising a body installed on the circuit board; at least one holding part, comprising a base fixed to the body, a lower end connected to the base and accommodated An elastic arm in the through hole and a buckle part connected to the lower end of the elastic arm, the elastic arm is made of thermal bimetal, which includes an active layer and a passive layer that are attached to each other, and the thermal expansion rate of the active layer is greater than The thermal expansion rate of the passive layer, the buckle part protrudes from the active layer to the direction of the passive layer, and the spring arm is bent toward the passive layer when heated, so that the buckle part buckles the circuit board. The spring arm includes a part that deviates from the base and extends downward The first arm, a second arm extending opposite to the first arm and inclined downward, and a first bending portion connecting the first arm and the second arm increase the length and elasticity of the elastic arm. After being heated, it is bent toward the passive layer, which can produce a large bending deformation so that the buckle part can firmly buckle the circuit board, and avoid warping and deformation of the main body due to heat.

Description

technical field [0001] The invention relates to an electrical connector, especially an electrical connector with a deformable holding part. Background technique [0002] In the prior art, most electrical connectors need to solder the conductive terminals to the circuit board. During the soldering process, the electrical connectors need to withstand high temperature, and its insulating body is easily warped and deformed due to thermal expansion. The Chinese patent application number 201710750719.0 discloses an electrical connector. The electrical connector has an insulating body and a plurality of conductive terminals provided on the insulating body. First holding devices are installed at both ends of the insulating body, and a The second holding device, wherein the second holding device is made of thermal bimetal, which can be actively bent and deformed by heat, and includes a second clamping part fixed in the insulating body, connected under the second clamping part and ins...
