Abstract
Providing an electrical component socket that enables stability of an electric resistance value to be maintained even after repeated use. A contact pin of the present invention includes: a lower contact portion; a spring portion that is provided so as to extend upward from the lower contact portion; a linear portion provided so as to extend upward from an upper end of the spring portion; and an upper contact portion that is formed on an upper end side of the linear portion. The upper contact portion includes a first contact protrusion arranged on an extension of the linear portion and a plurality of second contact protrusions arranged at respective positions off the extension of the linear portion.
Claims5
A contact pin to electrically connect a first electrical component and a second electrical component, the contact pin comprising:
- a lower contact portion to be electrically connected to a contact point of the first electrical component;
- a spring portion that is provided so as to extend above the lower contact portion, and in a pressed state, elastically deforms;
- a linear portion provided so as to extend upward from an upper end of the spring portion;
- and
- an upper contact portion that is formed on an upper end side of the linear portion, and in the pressed state, is brought into pressure contact with a terminal of the second electrical component by an elastic force of the spring portion,
- wherein the upper contact portion includes,
- a first contact protrusion arranged on an extension of the linear portion, in the pressed state, a distal end portion of the first contact protrusion being brought into pressure contact with the terminal of the second electrical component, and
- a plurality of second contact protrusions arranged at respective positions off the extension of the linear portion, in the pressed state, a distal end portion of each of the plurality of second contact protrusions being brought into pressure contact with the terminal of the second electrical component.
An electrical component socket comprising:
- a socket body that is installed on a first electrical component, and includes a receiving portion to receive a second electrical component;
- and
- a plurality of contact pins disposed in the socket body, in a state in which the second electrical component is pressed, the plurality of contact pins electrically connecting the second electrical component to the first electrical component, wherein
- each of the contact pins includes
- a lower contact portion to be electrically connected to a contact point of the first electrical component,
- a spring portion that is provided so as to extend above the lower contact portion, and in the pressed state, elastically deforms,
- a linear portion provided so as to extend upward from an upper end of the spring portion, and
- an upper contact portion that is formed on an upper end side of the linear portion, and in the pressed state, is brought into pressure contact with a terminal of the second electrical component by an elastic force of the spring portion, and
- the upper contact portion includes
- a first contact protrusion arranged on an extension of the linear portion, in the pressed state, a distal end portion of the first contact protrusion being brought into pressure contact with the terminal of the second electrical component, and
- a plurality of second contact protrusions arranged at respective positions off the extension of the linear portion, in the pressed state, a distal end portion of each of the plurality of second contact protrusions being brought into pressure contact with the terminal of the second electrical component.
