Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of connector, specifically is a kind of connector and terminal holding auxiliary structure of convenient bending terminal. BACKGROUND

[0002] Connector terminal holding auxiliary structure (Terminal Position Assurance) is abbreviated as TPA, also known as terminal position assurance, auxiliary lock sliding into connector shell to ensure that the terminal (or contact body) in the connector shell is completely in place in the shell. The lock slides into the groove on the terminal body, and the auxiliary lock will not engage correctly if the contact body is not correctly in place. After the terminal is completely in place, the lock can be inserted. TPA not only ensures that the contact body is correctly in place, but also helps to reduce the movement of the terminal in the connector. To remove the terminal from the connector shell, the TPA must be removed first.

[0003] The line end plastic sheath and TPA used in the market at present are separated and not integrated, which is easy to fall off and lose during use, and the use is very inconvenient, so an integrated anti-lost TPA is needed. SUMMARY

[0004] The utility model aims at providing a kind of connector and terminal holding auxiliary structure of convenient bending terminal.

[0007] By adopting the above technical scheme, the buckle body is pressed during use, at this time the buckle body is embedded in the locking groove, the end of the buckle body is embedded in the first embedding groove at the same time to achieve the effect of locking the wire body, and since the buckle body is locked with the locking groove, the effect of locking the line end plastic sheath body and the wire is achieved, and since the buckle body is hingedly connected to the line end plastic sheath body, it can be automatically aligned and locked by turning the buckle body to the specified position after unlocking, which is very convenient and quick to use and not easy to lose.

[0008] Further, the locking groove is provided with a second embedding groove on the lateral bottom wall, and the buckle body is provided with a protruding part embedded in the second embedding groove.

[0009] By adopting the above technical scheme, when the buckle body is embedded in the locking groove, the protruding part is embedded in the second embedding groove at the same time, so that the effect of preventing the rotation of the buckle body is achieved, thereby effectively locking the buckle body and achieving the effect of stably combining the wire end plastic sheath body with the buckle body.

[0010] Further, the wire end plastic sheath body is provided with a reinforcing rib fixed on the outer wall and crossing the locking groove, and the buckle body is provided with a rib groove for embedding the reinforcing rib.

[0011] By adopting the above technical scheme, the reinforcing rib can effectively improve the strength of the wire end plastic sheath body top wall to compensate for the physical defects caused by the locking groove, and the locking groove part is not easy to be broken under stress, and the rib groove can allow the reinforcing rib to pass through, avoiding the reinforcing rib from hindering the rotation of the buckle body.

[0012] Further, the wire end plastic sheath body is provided with a protruding secondary locking column, and the buckle body is provided with a secondary locking groove for embedding the secondary locking column.

[0013] By adopting the above technical scheme, the secondary locking column cooperates with the secondary locking groove to further improve the combination degree of the wire end plastic sheath body and the buckle body, and has good secondary locking effect.

[0014] Further, the metal terminal is provided with a plastic insulating block, the top outer wall and the side outer wall of the plastic insulating block are provided with a slot and a mounting groove, the metal terminal is fixedly arranged in the mounting groove, and the outer wall of the plastic insulating block is provided with a triangular block for bending the metal terminal.

[0015] By adopting the above technical scheme, in the currently used scheme on the market, whether the metal terminal is bent and then arranged in the plastic insulating block or arranged in the plastic insulating block and then bent, the operation is very inconvenient during bending. The triangular block can be used as a good bending fulcrum, and the metal terminal is bent by relying on the fulcrum, which is very convenient to use.

[0016] In summary, the beneficial technical effects of the utility model are as follows:

[0017] 1. The buckle body, the locking groove and the first embedding groove are hingedly arranged, which can lock the wire end plastic sheath body and the wire well, and automatically align and lock, which is very convenient and fast and not easy to lose.
