High-reliability connecting device and preparation process of shaft rod

Abstract

The invention relates to a high-reliability connecting device and a preparation process of a shaft lever. The connecting device comprises a base and a plug body arranged on the base, wherein pins arearranged on the plug body, the middle portion of the plug body is provided with an extended shaft rod used for being connected with a socket body, and a spiral clamping groove is formed in the end ofa drawing rod and comprises a vertical groove close to the end and a spiral groove communicated with the vertical groove. The invention further discloses a preparation process of the shaft rod. According to the invention, it can be guaranteed that the sliding block is rapidly and smoothly screwed into the spiral clamping groove, friction force is greatly reduced, and it is guaranteed that loosening cannot be generated after locking; when the plug body is separated from the socket body, time and labor are saved when the sliding block on the socket body is screwed out, and the purpose of rapid separation is achieved. and the shaft rod is made of a lubricating material and is good in wear resistance, and it can be guaranteed that the plugging frequency reaches 20000 times or above.

Description

technical field [0001] The invention relates to an automatic test system, in particular to a high-reliability connection device and a preparation process for a shaft. Background technique [0002] The automatic test system has been widely used in aerospace equipment. The entire system mainly includes computers, test instruments and interface adapters. The interface adapter is the signal hub between the equipment to be tested and the test instrument. It brings together a large number of Signal, its function is to transfer the signal of each interface of the device under test to the test instrument through different conditioning modules. Existing interface adapter devices are usually general-purpose interfaces, and users can automatically switch through computer-controlled matrix switches to adapt to different test objects, so as to realize the purpose of one test system corresponding to multiple test objects, and avoid repeated development of interface adapter devices. quest...

AI Technical Summary

Problems solved by technology

[0004] The middle part of the existing plug is usually equipped with a shaft through which the plug is fitted and connected to the socket. However, the number of plugging and unplugging of the existing shaft is usually three to four hundred times, otherwise the surface of the shaft will be completely worn out, and the shaft will After the rod is rubbed hundreds of times, particles will fall off the surface, which will make it impossible to continue to use and greatly reduce the service life

[0005] Furthermore, when the existing plug is connected to the socket, the friction force is large, and the connection cannot be quickly realized, and the disassembly is time-consuming and laborious, and it is not easy to quickly realize the disassembly, resulting in high difficulty in plugging and unplugging.
