CONTACT
First Claim
1. A contact comprising:
- a first conductor that has a fitting hole formed therein;
a second conductor that has a shaft that can be inserted into the fitting hole and an annular groove formed on an outer circumference of the shaft; and
an inclined coil spring that has a ring inserted into a coil, is circularly formed by the ring to be provided inside the annular groove, and is in contact with the annular groove and the fitting hole to electrically connect the first and second conductors.

Abstract
A contact includes a first conductor that has a fitting hole formed therein; a second conductor that has a shaft that can be inserted into the fitting hole and an annular groove formed on an outer circumference of the shaft; and an inclined coil spring that has a ring inserted into a coil, is circularly formed by the ring to be provided inside the annular groove, and is in contact with the annular groove and the fitting hole to electrically connect the first and second conductors. The inclined coil spring is helically wound in a shape of an ellipse and is provided inside the annular groove so that a long axis of the ellipse is directed to an axial direction of the shaft and a short axis is directed to a radial direction of the shaft. Axial-direction both ends of the ring are in contact with a long-axis inner circumference of the inclined coil spring.

11. A contact comprising:
-
a first conductor with a fitting hole at an end thereof, a central axis of the fitting hole coincides with a central axis of the first conductor; a second conductor with a shaft at one end thereof, the shaft provided with an annular groove formed on an outer circumference, the shaft configured to be inserted into the fitting hole of the first conductor; and an inclined coil spring assembly including a rigid ring member configured to be inserted into a coil member, the coil member being held in a circular shape by the rigid ring when the rigid ring member is inserted into the coil member, the inclined coil spring assembly configured to be arranged inside the annular groove in the second conductor, and the first conductor and the second conductor configured to be in electrical contact via the inclined coil spring assembly when the inclined coil spring assembly is arranged inside the annular groove and the shaft of the second conductor is inserted into the fitting hole of the first conductor.
