Problems solved by technology
[0004] The technical problem to be solved by the present invention is to provide a reliability detection device for electrical connectors in view of the deficiencies in the prior art. By detecting the holding force of the male and female plugs in the assembly workshop, it can be judged whether there is pin shrinkage in the electrical connector, and it can solve different problems. The reliability detection of male and female plugs of different models requires multiple detection devices, avoiding the loading of defective products, and ensuring the reliability of the product from the root

Embodiment Construction
[0064] The present invention will be described in detail below in conjunction with specific embodiments.
[0065] Such as figure 1 As shown, the electrical connector reliability detection device includes a load loading device 1, a detection front end 2 and a detection base 3. According to the principle of holding force detection, the present invention proposes an electric force applying device, which applies a rated pressure to the plug to be tested. The signal is transmitted through the resistance sensor and the single chip microcomputer, and the detection result is displayed through the host computer. The force applying device has high integration and low energy consumption, and can realize the detection of shrinkage phenomenon of male and female plugs of the same type.
[0066] The assembly drawing of load loading device 1 is as follows figure 2 As shown, it includes an electric push rod 11, a limit bracket 12, a micro switch 13, a synchronous beam 14, an electronic rule...

Description
technical field [0001] The invention relates to a reliability detection device for an electrical connector, which detects pin shrinkage of the electrical connector by comparing the holding force, and has universality for the detection of the reliability of various types of male and female plugs. Background technique [0002] With the development of China's rail transit, electrical connectors are more and more widely used in EMUs, high-speed rails, and subways. Due to poor contact of electrical connector pins, poor insulation, poor locking mechanism and other reasons, pin shrinkage directly leads to poor communication of locomotives, and even threatens the personal safety of passengers. [0003] There are four main methods for conventional reliability testing of electrical connectors: contact resistance testing, holding force testing, non-destructive testing, and transient testing. Contact resistance detection mainly uses contact resistance detectors, which are affected by f...
