Description

Technical Field

[0001] The utility model belongs to the technical field of electronic wiring harnesses, and in particular relates to a waterproof automotive electronic wiring harness. Background Art

[0002] The automotive electronic wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the components that are bundled to form a connecting circuit after the contact terminal (connector) made of copper material is crimped with the wires and cables, and then the insulator is plastic-pressed or metal shell is added.

[0003] At present, the wire end terminals of most automotive electronic wiring harnesses use plug-in methods to achieve circuit connection, and the terminals are fixed by interference fit. This simple plug-in connection method has poor sealing performance and is prone to water seepage. At the same time, due to the relatively small size of the terminal, the insertion operation is relatively simple, but in the later maintenance process, due to its small size, it is not easy to apply force, and it is usually pulled out by pulling the wire, which shortens the service life of the wire. Therefore, the utility model proposes a waterproof automotive electronic wiring harness, which aims to reduce the situation of repeated pulling of the wire due to the inconvenience of applying force when plugging and unplugging the terminal when disassembling the wiring harness, and effectively prevent the problem of water ingress into the terminal due to external environmental factors.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waterproof automotive electronic wiring harness, comprising a plurality of wires, a first terminal being provided at one end of the plurality of wires, a second terminal being provided at the other end of the plurality of wires, the first terminal and the second terminal being connected by plugging, a protective shell being fixed to the outside of the first terminal, a plug interface being provided at one end of the protective shell, card interfaces being provided on both sides of the protective shell, an elastomer being fixed at the base of the first terminal inside the protective shell, card blocks being fixed on both sides of the second terminal, the card blocks comprising a base, the base being a hollow structure, a hollow portion being provided at the center of one side of the base, a card connection portion being provided inside the hollow portion, and a side of the card connection portion being connected to a side of the hollow portion of the base.

[0006] As a preferred technical solution of the utility model, a plurality of the wires are arranged in a colinear manner and have a flat strip-shaped structure as a whole.

[0007] As a preferred technical solution of the present utility model, the shell and the protective shell of the first wiring terminal are an integrally formed structure, and the whole is made of PVC material.

[0008] As a preferred technical solution of the present utility model, the shell, the base and the clamping part of the second terminal are an integrally formed structure, and the whole is made of PVC material.

[0009] As a preferred technical solution of the utility model, a waterproof cover is fixed on the outer wall of the protective shell at the card interface, a sealing plate is provided at the base of the second terminal, the sealing plate abuts against the edge of the plug interface of the protective shell, and a sealing gasket is fixed on one side surface of the sealing plate.

[0010] As a preferred technical solution of the present utility model, the elastomer, the waterproof cover and the sealing gasket are all made of rubber.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model adopts a card interface of the outer protective shell combined with a card block on the terminal housing for card connection. By simply pinching the card blocks on both sides, the two terminals can be quickly disconnected. Compared with the traditional plug-in interference fit method, this design significantly reduces the situation where the wires are repeatedly pulled due to the inconvenience of applying force when plugging and unplugging the terminals when disassembling the wiring harness. This not only increases the service life of the wires, but also reduces the failure rate during use. In addition, the utility model also cleverly arranges an elastomer, which can effectively seal the connection of the terminal, thereby preventing the terminal from being flooded due to the influence of the external environment. This design enhances the waterproof performance of the terminal and improves its stability and reliability. Overall, the utility model has the advantages of simple structure, low manufacturing cost, and easy production and popularization. BRIEF DESCRIPTION OF THE DRAWINGS
