Abstract

A contact includes a first terminal including a plurality of arms; a second terminal; a spring connecting the arms to the second terminal; and a casing covering the spring, wherein the arms outwardly protrude from one end of the casing, wherein an interval between the arms increases from a side of the casing to front edges of the arms, wherein when the arms are pushed toward the casing the arms are retracted into the casing and contact an inner side of the casing so that the interval between the arms decreases.

First claim

What is claimed is:

1. A contact comprising:
a first terminal including a plurality of arms;
a second terminal;
a spring connecting the arms to the second terminal; and
a casing covering the spring,
wherein the arms outwardly protrude from one end of the casing,
wherein an interval between the arms increases from a side of the casing to front edges of the arms,
wherein when the arms are pushed toward the casing the arms are retracted into the casing and contact an inner side of the casing so that the interval between the arms decreases.

2. A contact for electrically connecting a first element to a second element, the contact comprising:
a first terminal contacting the first element;
a second terminal contacting the second element;
a spring connecting the first terminal and the second terminal;
a casing having a cylindrical shape;
a cantilever disposed between the first terminal and the spring; and
a rotation mechanism slanting relative to the longitudinal direction of the casing, and causing the cantilever to rotate relative to the casing so as to rotate the first terminal around an axial direction of the contact when the first terminal is pushed toward the casing.

3. The contact according to claim 2 ,
wherein the cantilever slants relative to a longitudinal direction of the casing, and
wherein, when the first terminal is pushed, the cantilever rotates relative to the casing so as to rotate the first terminal while contacting an inner side of the casing.

4. The contact according to claim 2 ,
wherein the cantilever is formed in a shape of going along a longitudinal direction of the casing,
wherein an opening slanting relative to the longitudinal direction of the casing is formed on the casing, and
wherein, when the first terminal is pushed, the cantilever rotates along the opening so as to rotate the first terminal.

5. A contact for electrically connecting a first element to a second element, the contact comprising:
a first terminal contacting the first element;
a second terminal contacting the second element;
a spring connecting the first terminal and the second terminal;
a casing having a cylindrical shape; and
a plunger disposed between the first terminal and the spring,
wherein the plunger includes a groove slanted relative to a longitudinal direction of the casing,
wherein the casing includes a bent portion, and when the first terminal is pushed, the bent portion moves along the groove so as to rotate the first terminal.
