Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically a wire harness connector. Background Technology

[0002] Wire harness connectors are key components for circuit connection and are widely used in automotive, electronics, and industrial fields. They are responsible for the transmission and connection of signals and power between circuits. With their adaptability, they meet the connection requirements of different circuits, and with their stable performance, they ensure the reliability of the connection. They are the basic hub for realizing circuit connection in various electronic systems and provide core connection support for the efficient operation of the overall circuit.

[0003] Existing wire harness connectors consist of the following structure: male plug, female plug, pin terminals, etc. The working principle is to precisely mate the male plug and female plug, and the terminals connect to form conductive contact, thereby building a current or signal path to achieve reliable circuit connection.

[0004] The existing wire harness connectors have the following drawbacks: the male and female terminals of the wire harness connector directly contact and rub against each other during mating. After repeated insertion and removal, friction marks or even grooves are easily formed on the terminal surface, which leads to a decrease in electrical connection stability. Friction and wear will shorten the service life of the terminals, and poor contact can reduce connection reliability and affect the continuous and stable operation of the overall circuit. Therefore, a wire harness connector is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing wire harness connectors, a new wire harness connector is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The wire harness connector of this utility model includes a female plug and a male plug connected by a snap-fit ​​mechanism. A terminal extending out of the female plug is assembled in the female plug through an assembly groove. The terminal includes a linkage part and a contact part located in the female plug. A copper busbar extending out of the male plug is assembled on the male plug. A drive frame is assembled on the male plug through an opening groove. One end of the drive frame is a drive part. After the male plug is inserted into the female plug, the drive frame inserts into the groove and drives the linkage part to swing, so that the contact part and the copper busbar fit together and abut against each other to achieve electrical connection.

[0007] Preferably, the drive frame has a through hole for the contact part to pass through so that it fits against the copper busbar.

[0008] Preferably, the drive frame is provided with limiting mechanisms on both sides to limit its movement. The limiting mechanism includes a locking rod rotatably mounted on the drive frame via a torsion spring and a rotating rod. One end of the locking rod is provided with a first locking tooth. The lock rod also includes a guide groove formed in a sliding groove that cooperates with the locking rod and the first locking tooth. The guide groove is provided with a second locking tooth and a third locking tooth that cooperate with the first locking tooth. When the first locking tooth and the second locking tooth are engaged, they are used to limit the drive part and the linkage part to always abut against each other, thereby ensuring that the contact part and the copper busbar are always in close contact to maintain the conductivity between the terminal and the copper busbar. When the first locking tooth and the third locking tooth are engaged, they are used to prevent the drive frame from falling off the male connector.

[0009] Preferably, an unlocking handle is provided at one end of the locking rod away from the mating surfaces of the female and male plugs, for removing the drive frame from the male plug.

[0010] Preferably, the female connector has a guide bevel at the opening of its mating surface.

[0011] The beneficial effects of this utility model are:

[0012] This utility model provides a wire harness connector that achieves contact by driving the terminals to swing through a drive frame, avoiding friction between the terminals and copper busbars during docking and undocking, preventing friction marks and grooves, significantly improving electrical connection stability, and the drive structure ensures tight contact, enhancing connection reliability and extending service life.
