In the process, the operation is convenient, the needle type terminal can be withdrawn from the interior of the plug body without the help of a needle plug, and the use is more convenient.

Description

Technical Field

[0001] The utility model relates to the field of automobile wiring harness connectors, and more specifically, to an automobile wiring harness plastic connecting connector. Background Art

[0002] The automotive wiring harness is the main body of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The automotive wiring harness is used to connect the various electronic components in the car and enable them to function. With the increasing number of modern car functions, automotive circuits are becoming more and more complex, and the corresponding wiring harnesses are also increasing. The connection and installation between wiring harnesses is an important part of the automotive circuit layout. In order to facilitate the connection between complex wiring harnesses in the car and improve the stability of the connection between wiring harnesses, automotive wiring harness connectors play an irreplaceable role in the connection of automotive wiring harnesses.

[0003] There are many types of connectors for existing automotive wiring harnesses, one of which is the widely used pin-type wiring harness connector. Although this connector has many advantages when used, it is not convenient to withdraw the pin after the pin-type terminal connecting wire is inserted into the hole inside the plug body during maintenance. The plug body must be unplugged and the handheld needle must be inserted into the hole before the pin-type terminal can be reversely ejected, which is inconvenient to use. Therefore, we propose an automotive wiring harness plastic connection connector to solve the above problems. Utility Model Content
