Claims

A contact capable of electrically connecting a first surface and a second surface arranged perpendicular to the first surface.
A base having a joint surface to be soldered to the first surface and
An elastic contact portion that elastically deforms and comes into pressure contact with the second surface,
With
The elastic contact portion includes an outer surface formed of one surface of a thin metal plate, an inner surface formed of the other surface of the thin plate, and a first end surface and a second end surface formed of an end surface of the thin plate. And, at least the outer surface is composed of a plating film provided on the surface of the thin plate.
The outer surface has a first range adjacent to the first end surface, a second range adjacent to the second end surface, and a third range between the first range and the second range. The surface in contact with the third range is used as a reference surface, the closer the first range is to the first end surface, the farther away from the reference surface, and the closer the second range is to the second end surface, the closer the reference is. is shaped away from the surface,
Even when the vicinity of the boundary between the first range and the third range or the vicinity of the boundary between the second range and the third range comes into contact with the second surface, the DC resistance value of the contact increases. Can be suppressed,
contact.

The contact according to claim 1.
The first range has a shape in which the thickness of the thin plate becomes thinner as the portion closer to the first end surface.
The second range has a shape in which the thickness of the thin plate becomes thinner as the portion closer to the second end surface.
contact.

A method for manufacturing a contact capable of electrically connecting a first surface and a second surface arranged perpendicular to the first surface.
The contact
A base having a joint surface to be soldered to the first surface and
An elastic contact portion that elastically deforms and comes into pressure contact with the second surface,
With
The elastic contact portion includes an outer surface formed of one surface of a thin metal plate, an inner surface formed of the other surface of the thin plate, and a first end surface and a second end surface formed of an end surface of the thin plate. And, at least the outer surface is composed of a plating film provided on the surface of the thin plate.
The outer surface has a first range adjacent to the first end surface, a second range adjacent to the second end surface, and a third range between the first range and the second range. The surface in contact with the third range is used as a reference surface, the closer the first range is to the first end surface, the farther away from the reference surface, and the closer the second range is to the second end surface, the closer the reference is. It is shaped to be away from the surface,
In the step of processing the first range into a shape closer to the first end surface and away from the reference surface, and in the step of processing the second range into a shape closer to the second end surface and away from the reference surface. The thin metal plate is tapped and processed .
Even when the vicinity of the boundary between the first range and the third range or the vicinity of the boundary between the second range and the third range comes into contact with the second surface, the DC resistance value of the contact increases. Can be suppressed,
How to make contacts.

The method for manufacturing a contact according to claim 3.
A method for manufacturing a contact that bends a portion where the tapping process has been performed by performing a bending process after the tapping process has been performed.
