Description

Technical Field

[0001] The present invention belongs to the technical field of electrical engineering, and particularly relates to a connector with an insertion-in-place detection function. Background Art

[0002] With the development of technology, connectors with single functions cannot meet the growing demands. In the fields of aviation, aerospace, ordnance, electronics, etc., connectors are usually used to achieve signal transmission between devices. For many precision electronic products, the requirements for the functional form and connection reliability of connectors are increasing day by day. It is not only required that the connector is small in size, light in weight, and reliable in use, but also required to have the ability to withstand harsh environments and functional diversity, such as waterproof, salt spray resistant, moisture resistant, dustproof, or heat preservation. At the same time, it is also necessary to determine whether the pinhole part is installed in place; ensure the reliability of the electrical connector and the safety of the device.

[0003] Chinese Patent No. CN221727500U discloses a jack assembly with an in-place detection function, including a front ejector rod, a rear ejector rod, a cylindrical helical spring, and a push-button switch. When in use, after the front ejector rod is subjected to pressure, the front ejector rod compresses the cylindrical helical spring to make the rear ejector rod apply pressure to the button of the push-button switch, and the push-button switch closes to output an electrical signal. However, the detection of the insertion in place of this jack assembly depends on the electrical signal output by the push-button switch. If an electrical signal is always output, it is impossible to determine whether the insertion is in place and whether a failure occurs. Summary of the Invention
