Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

As shown in fig. 1, a remote proximity switch includes a housing 1, a cable 2 and a base 3 assembled with the housing 1, the base 3 is assembled at the bottom of the housing 1, the housing 1 includes a sensing portion 14 and a threaded portion 15, the housing 1 is a hollow structure integrated as a whole, a clamping nut 7 is sleeved on the threaded portion 15, a through hole 9 and an indicating device 8 for inserting the cable 2 are formed in the base 3, a plurality of concave portions 5 are formed in the side portion of the base 3, and a protruding portion 4 matched with the concave portions 5 is formed in the lower portion of the housing 1.

Further, the conductive part of the cable 2 is made of copper and the surface layer is plated with zinc. The indicating device 8 is an indicating lamp with an emerald green outer cover.

Furthermore, the base 3 and the shell 1 are in compression joint, and the hardness of the base 3 is greater than that of the shell 1. The recess 5 comprises a narrow diameter 6 and a limiting cavity 10, and the shape of the convex part 4 is the same as that of the recess 5.

Further, the whole depressed part 5 is mushroom-shaped, that is, the radius of the left part of the limiting cavity 10 is larger than that of the narrow diameter 6, so as to form a limiting part. The inside portion of casing 1 still is equipped with the vertical guide way 12 that upwards extends of extension inside wall, then be equipped with on the lateral wall of base 3 with guide way 12 complex guide block 13, when base 3 along guide way 12 peg graft to casing 1 in the back reuse instrument extrusion set up the instruction piece 11 on the lateral wall of casing 1, be convenient for fully extrude bellying 4 and connect in the depressed part 5. The position of the indicating block 11 corresponds to the position of the protruding portion 4, that is, the indicating block 11 is used for facilitating the operator to observe the position of the protruding portion 4 from the outside, so that the operator can press the protruding portion 4 with a tool, and the connection is firmer.
