Abstract

The invention aims at providing a simple, convenient, fast and reliable internal filled waterproof wire bundle and a fabrication method thereof. The internal filled waterproof wire bundle is characterized by comprising wire bundle bodies and a solid filler, wherein gaps among the wire bundle bodies are fully filled with the solid filler. The fabrication method comprises the following steps: heating and melting the solid filler; coating the wire surfaces with the molten filler; putting the wires soaked with the filler into a mold, and closing the mold for cooling; and cooling and curing the wires, opening the mold, and taking out the wire bundle bodies, so as to obtain the internal filled waterproof wire bundle. The internal filled waterproof wire bundle fabricated by the method has the properties such as waterproofness, anti-leakage property, insulating property and chemical corrosion resistance; and the service life of the wire bundle can be greatly prolonged.

Description

technical field [0001] The invention relates to a waterproof wire harness and a manufacturing method thereof, in particular to an inner-filled waterproof wire harness and a manufacturing method thereof. Background technique [0002] The outer sealing and waterproofing of the wire harness is very easy to achieve, but the inner sealing and waterproofing of the wire harness is difficult to achieve. The reason is that it is difficult to completely fill the gaps between the wires inside the wire harness, so that the gaps between the wires form capillaries. Effect, thereby reducing the waterproof, anti-leakage and other performance of the wiring harness. [0003] In terms of filling and waterproofing of wire harnesses, Chinese patent CN1147042C discloses a wire harness sealing method and its waterproof structure. A sealant is applied to a wire containing a wire harness at a position where the wire harness A narrow diameter cylindrical part that passes part of a seal. The outer p...
