Wire joint connection terminal and wire joint connection method

Abstract

The invention discloses a wire joint connection terminal and a wire joint connection method. The wire joint connection terminal comprises a heat shrink tube and a copper tube, and the heat shrink tube wraps the copper tube which is arranged in the heat shrink tube. The wire joint connection terminal and the wire joint connection method have advantages that in connection and fixation of electric wires, great water tightness is guaranteed, and drawing force in connection of the electric wires is greatly increased.

Description

technical field [0001] The invention relates to the technical field of polymer material pipes, and in particular to a wire joint connection terminal and a wire joint connection method. Background technique [0002] In the joint connection process of existing electric wires and cables, the commonly used method is to peel off the ends of the electric wires and cables to be connected, wind and connect the cores inside, and then wrap them with electrical tape. The joints of this connection method are not firm and have poor waterproof performance, and during the use of the wires, the joints are in a state of energization and heat for a long time, which will accelerate the aging and shedding of the electrical tape, resulting in leakage, short circuit, etc. [0003] At present, some automobile industries directly use double-layer heat-shrinkable sleeves to seal and waterproof joints, which is more convenient and quicker than using electrical tape directly, and the sealing and water...

AI Technical Summary

Problems solved by technology

[0004] 1. In actual operation, because the heat-shrinkable sleeve can slide freely on the wire harness during the assembly process, it is difficult to locate the center. If one end is relatively close to the joint, this end will easily become a weak point for sealing and waterproofing, which will easily cause rainwater. Infiltrate from this joint location

[0005] 2. Use double-layer heat-shrinkable sleeves to wrap the wire harness joints, which only have the function of sealing and waterproofing, and cannot provide strong pulling force. When the two ends of the wire harness are pulled by a large external force, it is easy to cause the adhesive layer to peel off and produce gaps , will also cause the connector to loosen and fall off, losing the conductive function

[0006] To sum up, the current products and usage methods are prone to problems such as leakage, short circuit, and open circuit.
