Problems solved by technology

[0005] However, in the above-mentioned spring connector, when the front end surface of the conductive pin is in contact with the connection land of the battery, the spring force of the coil spring is locally concentrated on the front end surface of the connection land, so the gold plating of the connection land will be damaged. Floor
[0006] In addition, when the spring connector is connected to a large-capacity battery, high temperature is likely to be generated due to heat generated by contact resistance, and there is a problem that the electric capacity that can be energized decreases.

Embodiment 1

[0067] When the thickness of the arc-shaped thin-walled part is set to 0.1mm, the radius of curvature of the contact surface is set to 0.5mm, and the thickness of the base is set to 0.1mm, when a contact force of 0.9N is applied as a spring force, it is judged that The radius of curvature of the contact surface changes from 0.5mm to 0.7mm, and the contact pressure changes from 1210 (N / mm 2 ) to 967(N / mm 2 ). Thus, even with the same contact force, by increasing the radius of curvature of the contact surface, the contact area with the object to be contacted can be increased, local stress concentration can be alleviated, and damage to the contact pad of the battery can be prevented.

Embodiment 2

[0069] When the thickness of the contact surface of the arc-shaped thin-walled part is 0.1mm, the radius of curvature of the contact surface is 0.5mm, and the thickness of the base is 0.17mm, a contact force of 0.9N is applied as a spring force , it is judged that the radius of curvature of the contact surface changes from 0.5mm to 0.85mm, and the contact pressure changes from 1210(N / mm 2 ) to 849(N / mm 2 ). Thus, similarly to the above, by increasing the radius of curvature of the contact surface, the contact area with the object to be contacted is further increased, local stress concentration is alleviated, and damage to the contact pad of the battery can be prevented.

[0070] In addition, when the thickness of the arc-shaped thin-walled portion becomes thinner toward the base, even if a contact force is applied as a spring force, the radius of curvature of the contact surface does not change, and local stress concentration cannot be alleviated.

[0071] Therefore, the con...

Abstract

The purpose of the present invention is to provide a terminal wherein contact pressure is reduced without a biasing force against a movable contact part of said terminal being decreased, thereby preventing damage to a connection pad of a battery and preventing decreases in current-carrying capacity due to heating of the movable contact part. In order to produce said effects, said terminal (30) has a movable contact part (36) that can move between protruding from and not protruding from a contact hole (14) in a housing (10). Also, the movable contact surface (36a) of said movable contact part (36) is a thin, elastically-deformable circular arc (38).

Description

technical field [0001] The present invention relates to a terminal, which not only can be assembled into a housing to form a connector, but also can be directly mounted on the side end surface of a board for use. Background technique [0002] Conventionally, as a terminal, for example, there is a spring connector in which a conductive pin is disposed in a conductive tube so as to slide freely in the protruding and retreating directions without detachment, and the spring connector is compressed and provided with the pin. A coil spring in which a conductive pin is elastically biased in the protruding direction, wherein at least a part of the coil spring has an outer coil diameter smaller than or equal to an inner coil diameter of another part shifted by one turn. In a state where the coil spring is contracted, the one part can be accommodated inside the other part (refer to Patent Document 1). [0003] As in Patent Document 1 figure 1 As shown, the spring connector 20 utiliz...
