Embodiment 1

[0022] Embodiment 1, as figure 1 , figure 2 As shown, a plastic blocking piece with a short-circuit ring function includes a blocking piece body 7, which is a rectangular parallelepiped structure with one end open, and the shape of the blocking piece body 7 is adapted to the reserved wiring harness connector 1. The above-mentioned blocking member body 7 is provided with a short-circuit ring metal sheet 8 conducting through the two terminals 5 of the wire harness connector. The short-circuit ring metal sheet 8 can be a U-shaped structure. When in use, the plastic blocking piece 2 is inserted into the end of the wiring harness connector 1 . The short-circuit ring metal sheet 8 in the plastic blocking member 2 ensures the short-circuit conduction between the reserved wiring harness connector 1 that needs short-circuit conduction terminals 5 . Therefore, a common set of wiring harnesses can be used for different configurations, and the wiring harness connector 1 does not need ...

Embodiment 2

[0023] Embodiment 2. On the basis of the technical solution of Embodiment 1, a rectangular slot 6 is opened on the side of the plastic blocking member 2, and the size of the slot 6 is suitable for the locking and fixing structure 3 of the wiring harness connector 1. Matching, one end of the slot 6 extends to the sealing end surface of the plastic plug 2. The locking and fixing structure 3 of the reserved connector 1 is a triangular block structure, which is fixed with the slot 6 on the plastic plug 2 to prevent the plastic plug 2 from falling off during the movement. The reserved connector 1 is also provided with a press-loose locking and pulling-off structure 4, which facilitates the removal and insertion of the plastic plug 2 and provides convenience for future selection. The plastic plug 2 can be reused to save cost.

Embodiment 3

[0024] Embodiment 3. On the basis of the technical solution of Embodiment 1, the plastic blocking member 2 is provided with a limit structure 9 that is compatible with the end face of the wire harness connector 1, and the limit structure 9 is compatible with the wire harness connector. The elongated structure that matches the end faces of the 2 can well ensure that the plastic plug 2 is plugged in place, ensures the consistency of assembly, and can well protect the short-circuit terminal 5. In order to realize assembly more quickly and conveniently, an introduction surface 10 is provided on the inside of the plastic blocking member 2 to facilitate the extraction and insertion of the wire harness inserter 1 .

Abstract

The invention relates to a plastic plug with a short circuit ring function, comprising a plug body which is adapted to a wiring harness connector in appearance; the plug body is in a rectangular structure with one end being open; and the plastic plug with the short circuit ring function is characterized in that: a short circuit ring metal sheet for communicating two terminals of the wiring harness connector is arranged in the plastic plug body. A rectangular groove hole is arranged on the side surface of the plug body, and the size of the groove hole is adapted to the locking and fixing structure of the wiring harness connector. A limit structure which is adapted to the end surface of the wiring harness connector is arranged in the plastic plug. The plastic plug with the short circuit ring function has a simple structure, is convenient to assemble, has low cost, can effectively solve the problem that the terminal of the pre-reserved wiring harness connector is in short circuit, is firmly fixed with the pre-reserved wiring harness connector, protects the wiring harness connector against damage, reduces the number of parts of a complete vehicle, is convenient for the management of the parts, and can be widely applied to the field of vehicle wiring harnesses.

Description

technical field [0001] The invention relates to a wire harness plug-in block, in particular to a wire harness plug-in block with a short-circuit ring function used on a vehicle. Background technique [0002] With the widespread use of automobiles and the great increase in the number of electrical components in automobiles, the electrical safety of the entire vehicle has received more and more attention. As the transmission carrier of vehicle power supply - vehicle wiring harness, its safety and reliability have been paid more and more attention. [0003] As the key carrier of vehicle power transmission and conduction, the harness connector needs necessary and reliable protection measures and appropriate fixing methods to ensure stable contact conduction, so as to prevent unreliable contact conduction or internal abnormal short circuit after driving. , resulting in serious consequences such as electrical failure and even vehicle ablation. [0004] Common harness connector p...
