Claims

[Scope of utility model registration request]

(1) In a proximity switch equipped with a detection coil that is closely installed at least on the inner wall of the box-shaped case,
A locking part having a gap between the inner wall of the case and the back surface of the detection coil, and a spring device inserted into the gap to press the back surface of the detection coil are provided, and the detection coil is connected to the inner wall. A proximity switch characterized by being in close contact with the switch at all times.

(2) Utility Model Registration Scope of Claim 1 In the device described in claim 1, the spring device has both ends formed in narrow grooves perpendicular to the central axis of the detection coil formed on both side walls of the case as the locking portions. A proximity switch characterized in that it is a leaf spring that is locked and curved toward the back surface of the detection coil.

(3) Utility Model Registration Scope of Claim 1 In the device described in claim 1, the spring device includes a protrusion inserted into a groove of a locking post formed in the case as the locking portion, and a projection into which the detection coil is fitted. A proximity switch characterized in that it is an arcuate spring integrally formed with a support shaft that is fitted into a shaft center hole of a yoke, and spring plates whose both ends press against the back surface of the detection coil.
