Description

Technical Field

[0001] The utility model relates to the technical field of wiring connectors, in particular to a connector for preventing wiring from loosening. Background Art

[0002] The wiring harness connector is a type of terminal. The connector is also called a connector, plug and socket in China. It generally refers to an electrical connector, that is, a device that connects two active devices to transmit current or signals. The connector is a component that our electronic engineering technicians often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function. The connector is an indispensable component in electronic equipment. The wiring harness connection components need to have good anti-loosening properties to avoid being hindered when affected by the outside world.

[0003] For example, a Chinese utility model patent with authorization announcement number CN219979956U discloses a wiring harness connector that prevents connectors from loosening. The plug mechanism and the socket structure are connected by a snap-on mechanism. The plug mechanism includes a connecting plug and a connecting plug block. The socket structure includes a connecting socket. A connecting slot is provided on the front side of the connecting socket. The connecting plug is connected to the inner side of the connecting slot through the connecting plug block. The snap-on mechanism is arranged on the top of the connecting socket. The snap-on mechanism includes a limiting card strip. The connector is different from a traditional snap-on limiting structure and adopts an inserted limiting structure. The limiting card strip is used to limit and lock the connecting plug block. The structure is simple and reliable, with higher structural stability and service life. There is no need to perform grooving on the inside of the connecting socket and the connecting plug, which greatly reduces the manufacturing difficulty and processing cost of the connector. The limiting card strip can be disassembled by simply lifting it up, which is more convenient to disassemble than the snap-on structure.

[0004] However, the existing wiring harness connector that prevents the wiring from loosening needs to be installed by inserting a limit card strip and fixing the limit card strip by a card strip fixing seat during use, so as to complete the installation of the wiring harness connector. When disassembling, the limit card strip needs to be lifted up with the end of a flat-head screwdriver, and long-term lifting can easily cause damage to the limit card strip.

[0005] Therefore, we propose a connector that prevents wiring from loosening to solve the above problem. Utility Model Content
