Description

Technical Field

[0001] The utility model relates to the technical field of circuit terminal detection equipment, in particular to a detection and conduction jig for male terminal connectors. Background Art

[0002] As is well known, with the development of industrial modernization and automation technology, circuits are more and more widely used. For example, the circuits of equipment such as numerical control machine tools, agricultural machinery, and automobiles are more and more numerous and complex, and their terminal connectors are also more and more numerous. The quality of the terminal connectors is directly related to the stability of the use performance and the service life of the equipment.

[0003] At present, a terminal connector generally includes a terminal fixing shell, a terminal wire, a terminal plug, and a wire pressing plate. The side of the terminal fixing shell is provided with a wire pressing plate mounting hole. The front side of the terminal fixing shell is fixedly connected to the terminal plug. The terminal wire is inserted into the terminal fixing shell, and the end of the terminal wire is connected to the terminal plug. The wire pressing plate is mounted on the wire pressing plate mounting hole on the side of the terminal fixing shell. Since the detection and conduction jig for terminal connectors is divided into a detection jig for female terminal connectors and a detection and conduction jig for male terminal connectors, for the detection and conduction jig for female terminal connectors, the terminal plug on the female terminal connector is hidden inside the terminal fixing shell, and then the conduction detection is carried out by inserting a detection probe into the terminal fixing shell to dock with the terminal plug. For the detection and conduction jig for male terminal connectors, the terminal plug on the male terminal connector is exposed outside the terminal fixing shell, and the conduction detection is carried out by inserting the exposed terminal plug into the detection probe. However, since the terminal plug of the male terminal connector is exposed outside, when it enters the inside of the conduction jig, the terminal plug of the male terminal connector is extremely likely to be offset. Once it is offset, it is very difficult to dock with the detection probe, which is not convenient for subsequent detection, resulting in a high rejection rate of the terminal connectors. Moreover, since the terminal connectors collide with the conduction jig during the detection docking process, the service life of the conduction jig is also reduced. Summary of the Invention

[0004] The purpose of the utility model is to solve the above-mentioned deficiencies of the prior art, and provide a detection and conduction jig for male terminal connectors with simple structure, convenient use, stable docking, low rejection rate of terminal connectors, and long service life of the conduction jig.
