Description

Technical Field

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

[0002] With the development of electric vehicles, there are more and more types of connector outlets. Straight outlets can no longer meet the requirements of vehicle wiring. More and more occasions require connectors with 90-degree outlets or other angle outlets. Bent connectors involve the connection of two cross-directional contact terminals, usually through side-opening covers or one-piece injection to achieve terminal fixation in two directions.

[0003] However, when using a side cover for fixing, it is necessary to consider the sealing problem at the side cover installation point, which increases the risk of product sealing failure, while increasing the number of parts, further increasing the part cost. When using cross terminals and inserts for integrated injection, the insert product has low production efficiency and low yield, which is not convenient for mass production. Utility Model Content

[0006] As a preferred solution, the contact piece is a socket contact piece, and the transfer contact piece is a sheet contact piece.

[0007] As a preferred solution, the front end of the contact piece is provided with an insertion cavity for plugging and mating with the adapter contact piece, the fastener is arranged in the insertion cavity and has a threaded portion protruding from the rear end of the contact piece, and the adapter contact piece is provided with a locking nut for threadedly mating with the threaded portion and locking.

[0008] As a preferred solution, a first through hole for the threaded portion to pass through is provided at the rear end of the contact piece, and a second through hole for the threaded portion to pass through is provided on the transition contact piece.

[0009] As a preferred solution, a hexagonal countersunk hole is provided at one end of the fastener away from the threaded portion.

[0010] As a preferred solution, a groove is provided on the inner wall of the insertion cavity, and a contact spring is provided in the groove.

[0011] As a preferred solution, the invention further comprises a shell and an insulator arranged in the shell, and the contact piece and the transfer contact piece are both arranged in the insulator.

[0012] As a preferred solution, the connection method between the transition contact and the cable includes but is not limited to crimping or welding.

[0013] The beneficial effects of the present application are as follows: 1. The present application realizes the connection between the contact piece and the transfer contact piece by setting fasteners, without opening the side cover, thereby reducing the risk of product sealing failure. In addition, compared with the existing side cover opening method, the present application reduces the number of parts and reduces product costs.

[0014] 2. The contact piece and the transfer contact piece of the present application can be processed separately, thereby avoiding the problem of low production efficiency and low yield rate caused by the use of one-piece injection molding of inserts.

[0015] 3. When the present invention is used for fastening connection, the fastener is rotated while the contact piece remains stationary, thereby effectively avoiding wear on the mounting surface of the contact piece. BRIEF DESCRIPTION OF THE DRAWINGS
