Abstract
Description
Technical Field
[0001] The utility model relates to the field of spring contact fingers, in particular to a detection mould for extremely fine wire spring contact fingers. Background Art
[0002] Spring contacts are a new type of electrical connection product with the advantages of simple structure, easy assembly, multiple contact points, good conductivity, strong current capacity and low wear. These advantages make spring contacts more and more popular with customers and widely used in high-voltage switches, high-speed railways, petroleum exploration and testing equipment, new energy vehicles and other fields.
[0003] The coil of the spring contact finger is elliptical and has a certain inclination angle. When the contact finger is compressed, each coil will deform individually. No matter which part of the coil is deformed, it will drive the entire ring of contact fingers to react, so that the load of each coil remains consistent. Under a large working compression, the contact pressure of each coil can be kept almost constant.
[0004] The quality of the spring contact finger directly affects the conduction effect. However, the existing detection method generally requires the spring contact finger to be installed in the electrical component and then the electrical component is connected before the detection can be performed. The detection process is very cumbersome.

[0019] The utility model aims to provide a detection die for an extremely fine wire spring contact finger to solve the problems existing in the prior art.
[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0021] Embodiment 1:
[0022] The present embodiment provides a detection mold for an ultra-fine wire spring contact finger, comprising a detection platform 1, guide rail brackets 2 are provided on both sides of the detection platform 1, an upper mold assembly 3 is provided on the top of the guide rail bracket 2, a detection result display assembly 4 is provided on the upper mold assembly 3, a lower mold assembly 5 is slidably provided on the guide rail bracket 2, and an electric push rod 6 is provided between the lower mold assembly 5 and the detection platform 1.
[0023] Specifically, the upper mold assembly 3 includes an upper detection plate 31, a first annular groove 32 is provided at the bottom of the upper detection plate 31, multiple groups of contact electrodes are distributed in the first annular groove 32, each group of contact electrodes is provided with two relatively non-contacting pole pieces 33, and the pole pieces 33 are electrically connected to the result display assembly 4.
[0024] Furthermore, the upper detection board 31 is made of insulating material.
[0025] Furthermore, the result display component 4 includes a detection panel 41 , on which an LED detection light 42 is provided. The LED detection light 42 is connected to the electrode 33 via a wire 43 , and a button battery 44 is connected to the wire 43 .
[0026] Furthermore, the lower mold assembly 5 includes a lower detection plate 51 , which is slidably disposed on the guide rail bracket 2 , and a second annular groove 52 is disposed on the top of the lower detection plate 51 , and the second annular groove 52 is disposed opposite to the first annular groove 32 .
[0027] Furthermore, the number of the electric push rods 6 is 2, thereby ensuring smooth lifting and lowering.
[0028] The utility model provides a detection mold for an ultra-fine wire spring contact finger, and its working principle is: the spring contact finger is placed in the second annular groove 52, and the lower detection plate 51 is raised by the electric push rod 6, so that the spring contact finger is limited in the first annular groove 32. If the spring contact finger has no defects, the spring contact finger can contact the pole piece 33, so that the LED detection light 42 at the corresponding position forms a path and lights up. If there is a defect at a certain position of the spring contact finger, then the position becomes unable to conduct, so as to detect the conduction effect of the spring contact finger.
