Abstract

The invention provides an automatic detection device and detection method of pin shrinkage of an aviation electrical connector contact, and belongs to the technical field of electrical connectors. Theinvention aims at solving the problems of numerous blind spots and inaccurate visual positioning of substations caused by manual inspection. The automatic detection device of the pin shrinkage of theaviation electrical connector contact provided by the invention comprises a detection platform and an upper computer; a motor is driven by the upper computer to drive a three-dimensional movement mechanism to move so as to drive a visual detection mechanism and a pin shrinkage detection mechanism to move to perform movement on an electrical connector to be tested installed on an electrical connector mounting mechanism; and the pin shrinkage detection mechanism sequentially contacts each contact pin on the electrical connector to be tested, applies a constant force to each contact pin, simultaneously obtains the displacement value of each contact pin and uploads the displacement value to the upper computer, and the upper computer generates a measurement table based on the displacement value, and judges whether the contact pin generates a pin shrinkage phenomenon according to the displacement value to completes the automatic detection process. The automatic detection device provided bythe invention is used for performing automatic detection on electrical connector contacts.

Description

technical field [0001] The invention relates to an automatic detection device and a detection method for pin shrinkage of a contact part of an electrical connector, belonging to the technical field of electrical connectors. Background technique [0002] Electrical connectors are widely used in various instrumentation and aerospace system engineering. They play the role of signal transmission and power transmission in the system. Therefore, the reliability and safety of electrical connectors are crucial to the entire system engineering. important. 80% of aviation electrical connectors use crimping type high-density plugs / seats, which are characterized by small size, high contact density, and strong anti-electromagnetic interference. [0003] Because the pins and sockets of the electrical connector are thin and have a high density, faults such as pin shrinkage, shrinkage cavity, broken pin, and deformation are prone to occur during the disassembly, assembly, docking, and proc...
