Description

Technical Field

[0001] The present application belongs to the technical field of automobile controller wiring harnesses, and more specifically relates to a waterproof and tensile-resistant automobile wiring harness. Background Art

[0002] A car is a collection of high-tech content. There are various car supporting devices inside the car. A large number of controller harnesses are needed to connect the car supporting devices and the car controller. The controller harness is equipped with a connector, and the car supporting device is equipped with a connector socket. The connector card is inserted into the connector socket for electrical connection. The structure, connection firmness, and sealing and waterproof performance of the controller harness greatly affect the connection and conduction between the equipment.

[0003] At present, the wiring harnesses on cars need to have good waterproof properties to ensure their reliability under long-term exposure to harsh conditions. Existing controller wiring harnesses are generally wrapped with waterproof tape, which is prone to aging and detachment, causing liquid to enter the wire along the core wire, affecting the use of the wiring harness and even causing safety accidents in serious cases. Therefore, there is still room for improvement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a waterproof and tensile-resistant automobile wiring harness, which has the advantages of being able to effectively provide dual protection for the core wires, both waterproof and protective, and having a simple structure and high practicality.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waterproof and tensile-resistant automotive wiring harness, comprising a plug-in connector, a wire connected to the plug-in connector through a wiring terminal, the wire having a core wire unit and an outer sheath wrapped around the core wire unit, the core wire unit comprising a first connecting part and a second connecting part, a tensile-resistant copper terminal is riveted between the first connecting part and the second connecting part, the gaps between the two ends of the tensile-resistant copper terminal and the first connecting part and the second connecting part are filled with a solder paste layer, the circumferential surface of the tensile-resistant copper terminal is covered with a waterproof adhesive layer, and the outer side of the waterproof adhesive layer is wrapped with a waterproof tape.

[0006] By adopting the above technical scheme, firstly, the first connection part and the second connection part of the core wire unit can be reconnected through the tensile copper terminal, and the connection part will not be separated due to the influence of external tension, and at the same time, the liquid can be blocked from entering the inside of the wire through the second connection part; secondly, the solder paste layer can tightly seal the gap between the two ends of the tensile copper terminal and the first connection part and the second connection part, thereby effectively preventing the liquid from entering the inside of the wire of the car through the gap; finally, the waterproof adhesive layer completely covers the circumferential surface of the tensile copper terminal, which can effectively block the penetration of liquid, and at the same time, the waterproof tape is wrapped between the first connection part and the second connection part, which can prevent the waterproof adhesive layer from falling off due to heat aging, while playing a dual protection role of waterproofing and protecting the core wire unit.

[0007] In a preferred embodiment, there are two wires, and a waterproof protective cover is provided on the outside of the two wires and between the first connecting portion and the second connecting portion.

[0008] By adopting the above technical solution, the waterproof protective cover can form a barrier at the connection between the first connecting part and the second connecting part, effectively preventing liquid from penetrating into the core wire unit.

[0009] In a preferred embodiment: the waterproof protective cover is made of insulating rubber.

[0010] In a preferred embodiment: both ends of the waterproof protective cover are provided with water-blocking straps.

[0011] By adopting the above technical solution, the water-blocking tape can form a closed space inside the waterproof protective cover, thereby further preventing liquid from contacting the core wire unit.

[0012] In a preferred embodiment: a nylon woven mesh is provided between the waterproof adhesive layer and the waterproof adhesive tape and covers the first connecting portion and the second connecting portion.

[0013] By adopting the above technical solution, the nylon braided mesh improves the tensile strength of the wiring harness, ensuring that the first connecting part and the second connecting part will not be detached due to external tension, thereby ensuring the stability of the wiring harness data transmission.

[0014] Compared with the prior art, this application has the following beneficial effects:

[0015] 1. The first connection part and the second connection part of the core wire unit can be reconnected by the tensile copper terminal, and they will not be separated due to the influence of external tension, and at the same time, the liquid can be prevented from entering the inside of the wire through the second connection part;

[0016] 2. The gaps between the two ends of the tensile copper terminal and the first connecting part and the second connecting part can be tightly sealed by the solder paste layer, thereby effectively preventing liquid from entering the interior of the wire of the car through the gap;

[0017] 3. The waterproof adhesive layer completely covers the circumferential surface of the tensile copper terminal, which can effectively block the penetration of liquids. At the same time, the waterproof tape is wrapped between the first connection part and the second connection part, which can prevent the waterproof adhesive layer from aging and falling off due to heat, and play a dual role of waterproofing and protecting the core wire unit.
