Detecting switch and mfg. method thereof

Abstract

The invention relates to a detecting switch and the manufacturing method thereof. And the detecting switch comprises a base, two terminal buses arranged in the base, a sliding unit and as elastic component and a top cover for covering the base, where two side walls of surrounding wall of the base has a limiting surface and a guiding incline each; the sliding unit comprises a slide block arranged in the base and a connection piece fixing the slide block and limited between the two limiting surfaces, two opposite sides of sliding part of the slide block contact with the two guiding inclines, respectively, and the sliding block can drive the connection piece to move between a connection position and a non-connection position, relative to the base. Relative to the existing techniques, the invention can reduce the production cost, prolong the service life and improve the action stability much.

Description

technical field [0001] The invention relates to a detection switch and a manufacturing method thereof, in particular to a detection switch with high operation stability. Background technique [0002] Such as figure 1 , 2 As shown, a conventional detection switch 1 includes a rectangular base 11 , two metal terminal blocks 12 , a sliding unit 13 , an elastic element 14 and an upper cover 15 . [0003] The base 11 is made of plastic material, including a bottom wall 111, a surrounding wall 112 extending upwards from the periphery of the bottom wall 111, the two cooperate to define a chamber 113 with an open end, and a The limiting groove 114 is formed on the inner surface of the bottom wall 111 . [0004] The two terminal rows 12 are buried on the inner surface of the bottom wall 111 at intervals. [0005] The sliding unit 13 includes a plastic slider 131 slidably arranged in the chamber 113 of the base 11, and a metal guide piece 132 fixed on the slider 131, the guide pie...

AI Technical Summary

Problems solved by technology

[0009] 1. The guide piece 132 and the slider 131 are assembled by embedding and injection. When manufacturing the sliding unit 13, the guide piece 132 needs to be positioned first, and then plastic material is injected to form the slider 131. This sliding unit 13 has the disadvantage of increasing the cost due to the long man-hours required for embedding and injection. In addition, when the conductive piece 132 is embedded in the slider 131, it is also prone to deformation, which reduces the product yield of the sliding unit 13. Decrease, indirectly increase manufacturing cost

[0010] 2. The bottom plane of the sliding part 1312 of the slider 131 is in surface contact with the straight surface of the limiting groove 114 of the base 11. When the sliding part 1312 slides in the limiting groove 114, it will It produces a large friction force, which makes the components wear more and reduces the service life; it is worth mentioning that when the user presses the pressing part 1311 with an improper direction of force, it will cause the slider 131 and the sliding part 1312. Uniform wear, coupled with the original defect of greater wear, will accelerate the shortening of its service life

[0011] 3. Moreover, there is a gap between the left and right sides of the sliding part 1312 of the slider 131 and the limiting groove 114 of the base 11. figure 2 As shown in the gap 2, when the user presses the pressing part 1311 with an inappropriate direction of force, the sliding part 1312 will slide to the left or right, causing the contact between the guide piece 132 and the two terminal blocks 12. Decreased operational stability of electrical connections
