Problems solved by technology

However, due to long-term vibration conditions, it is very easy to cause solder joints to open, and oil and water immersion can easily cause short circuits at the soldering joints of the wire cores, and interference signals can easily enter the system through cables, affecting the normal operation of the system.

Embodiment Construction

[0021] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0023] A kind of automotive cable potting method, such as figure 1 , 2 shown, including the following steps:

[0024] After the wire core 2 is welded, use the heat shrinkable tube 3 to heat shrink it, pour 704 adhesive 1 in the welding place, and solidify to form a protection for the solder joint, ensure the reliability of the connection, and make the connection place withstand a certain pulling force;

[0025] After the 704 adhesive 1 is completely cured, use the heat-shrinkable tube 3 to heat-shrink and fix the core 2 and the single-core wire shielding layer 4 to prevent the single-core wire shielding layer 4 from moving and being damaged, thereby puncturing the wire core 2 and causi...

Abstract

The invention provides a vehicle cable filling and sealing method. The method comprises the following steps: after being welded, wire cores are thermally shrunk by using heat-shrinkable tubes, 704 adhesives are filled at the welding positions, and curing is carried out; after the 704 adhesives are completely cured, the wire cores and shielding layers are fixed through the heat-shrinkable tubes; atail accessory is installed and fixed, 704 adhesives are filled for the second time, and the 704 adhesives are cleaned outside the tail accessory after the 704 adhesives are cured; a wave-proof sleeveis fixed at a groove of the tail accessory by using a silver-plated copper wire; and sleeving with a thermal shrinkage head is performed, and thermal shrinkage is performed. The cable filling and sealing method provided by the invention has the advantages of good sealing performance, pulling resistance and excellent electromagnetic shielding performance, and can greatly improve the reliability and electromagnetic compatibility of the cable.

Description

technical field [0001] The invention belongs to the technical field of cable potting, and in particular relates to a method for potting cables for vehicles. Background technique [0002] Some vehicles need to work in a harsh working environment, the electromagnetic environment is complex, and the reliability of the cable is extremely high. It must not only adapt to the working environment of high temperature and strong vibration, but also occasionally withstand the erosion of oil and water immersion. Therefore, the cables in this environment are prone to open circuit, short circuit, electromagnetic interference and other problems, which affect the reliability of the system work. [0003] The current common cable design method is to heat shrink the wire core with a heat shrinkable tube after welding, and then cover the heat shrinkable head after installing the fixed tail accessory. However, due to long-term vibration conditions, it is very easy to cause solder joints to open...
