Problems solved by technology

At present, most automobile wiring harness terminal connector protection methods are to use insulating tape to wrap multiple turns after the wire connector is completed. This method has disadvantages such as poor sealing, poor weather resistance, and oil resistance. Failure of the electronic system of the vehicle, which in turn leads to a safety accident of the vehicle, resulting in loss of personnel and property

Abstract

The invention discloses a water-proof, oil-resistant, flame-retardant and environment-friendly heat-shrinkable double-wall miniature seal cap for an automobile wiring harness end connector and a manufacturing method thereof. An outer wall is prepared from polyethylene, oil-resistant rubber, silicon rubber, a flame retardant, a thermal stabilizer, an antioxidant, a lubricant, a sensitized crosslinking agent and carbon black; an inner wall and a cap end plug are made of modified polyamide hot-melt adhesive. The double-wall miniature seal cap is manufactured by mixing, granulating, co-extruding, irradiating, expanding, sealing a cap end and other processes; the manufactured water-proof, oil-resistant, flame-retardant and environment-friendly heat-shrinkable double-wall miniature seal cap for the automobile wiring harness end connector has excellent wear resistance, oil resistance, flame retardance and water repellency, and meets RoHS standards; the manufacturing method has the characteristics of simple and quick operation, and reduction in labor intensity; according to the manufacturing method, phenomena such as loosing, falling and damping are avoided, and finally long-term operation stability of an electronic system is ensured.

Description

technical field [0001] The invention relates to a waterproof, oil-resistant, flame-retardant, environment-friendly, heat-shrinkable double-wall mini cap for automobile wire harness terminal joints and a preparation method thereof, belonging to the field of protection for automobile wire harness terminal joints. Background technique [0002] The automobile wiring harness is equivalent to the neural network of the automobile, which is used to convey various instruction information and telecommunication signals, so that the whole vehicle is in a better control and operation state. At present, most automobile wiring harness terminal connector protection methods are to use insulating tape to wrap multiple turns after the wire connector is completed. This method has disadvantages such as poor sealing, poor weather resistance, and oil resistance. This will lead to the failure of the electronic system of the vehicle, which will lead to a safety accident of the vehicle and cause loss...
