Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a connector straight plug. Background Art

[0002] Electrical connectors are indispensable electronic components for various electrical and electronic systems, and are widely used in aerospace, aviation, nuclear industry, weapons, ships, electronics, transportation, computers, communications, medical treatment, oil exploration and other industries. As the "nerve hub and contact point" of the electrical signal transmission system, electrical connectors play a key bridge role in the transmission of electrical signals in the circuit. Their quality directly affects the performance and quality of the product. In the practical application of electrical connectors, taking straight connectors as an example, when using them, the connectors not only need to consider the sealing problem, but also the connection stability of both ends of the connector. When the cable is pulled hard or subjected to other torsional forces during use, how to ensure the connection stability of the connector to the harness at both ends and the assembly stability of the connector itself is as important as the sealing stability, because unstable connection will inevitably affect the use of the connector. Therefore, a straight connector plug is needed. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a straight connector plug, which is used to solve the problem of connection stability when the connector is used in the prior art.
