A high-reliability connecting device and a preparation process for a shaft rod

Abstract

A high-reliability connection device and a preparation process for a shaft, the connection device includes a base and a plug body arranged on the base, the plug body is provided with pins, and the middle of the plug body is provided with an extension for connecting with the socket body. The shaft rod is connected; the end of the drawing rod is provided with a spiral clamping groove, and the spiral clamping groove includes a vertical groove near the end and a spiral groove communicated with the vertical groove. The invention also includes a preparation process of the shaft rod. On the one hand, the present invention can ensure that the sliding block is fast and smoothly screwed into the spiral groove, greatly reduces the friction force, and ensures that there will be no loosening after locking; when the plug body is separated from the socket body, the When the slider is unscrewed, it saves time and effort, and achieves the purpose of rapid separation; on the other hand, the shaft material is lubricated and has good wear resistance, which can ensure that the number of insertions and withdrawals can reach more than 20,000 times.

Description

technical field [0001] The invention relates to an automatic test system, in particular to a high-reliability connecting device and a preparation process of a shaft rod. Background technique [0002] The automatic test system has been widely used in aerospace equipment. The entire system mainly includes a computer, a test instrument and an interface adapter. The interface adapter is the signal hub between the equipment to be tested and the test instrument. Its function is to transfer the signals of each interface of the device under test to the test instrument through different conditioning modules. The existing interface adaptation device is usually a general interface, and the user can control the matrix switch through the computer to automatically switch to adapt to different test objects, so as to achieve the purpose of one test system corresponding to multiple test objects, and avoid the repeated development of the interface adaptation device. question. [0003] The e...

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.
