Description
Technical Field
[0001] The utility model relates to the technical field of wire harness connectors, in particular to an automobile wire harness connector capable of preventing oxidation. Background Art
[0002] Automotive circuit diagrams are composed of multiple functional unit circuits. A typical circuit includes a power supply, electrical devices, switches, fuses, and wiring. Automotive circuits have both commonalities and unique characteristics, such as the use of batteries as power sources and the use of the vehicle body to form circuits. The diverse range of electrical components leads to complex circuits and diverse representations. Automotive circuits are often connected using wiring harnesses, which are then connected to each other and to electrical components via connectors to ensure circuit integrity and functionality.
[0003] For example, an automotive wiring harness connector with publication number CN217009740U includes a locking bolt, a plurality of shaped parts, an extrusion part, an arc-shaped groove, and a connecting column. When using the automotive wiring harness connector, after first connecting the male connector and the female connector, the locking bolt is rotated to bring the plurality of shaped parts closer to each other, so that the plurality of shaped parts drive the extrusion part closer to each other through the connecting column, and the extrusion part clamps the connecting wire through the arc-shaped groove, so that the connecting wire is firmly connected to the male connector and the female connector. Then, the male connector and the female connector are plugged together. At this time, the male connector first squeezes the protrusion, causing the elastic plastic sheet to deform, so that the male connector can be continuously inserted. When the male connector is fully inserted into the female connector, the protrusion corresponds to the groove. Under the elastic action of the elastic plastic sheet, the protrusion is inserted into the groove, so that the male connector and the female connector are initially fixed.
[0004] Based on the above connector and in combination with related connectors in the prior art, it is found that although the existing automotive wiring harness connectors are sealed to reduce the formation of an oxide layer on the contact surface, the contacts are still easily exposed to the air after the male and female connectors are separated. In order to solve the problems existing in the prior art, the present application proposes an automotive wiring harness connector that prevents oxidation. Utility Model Content
