Common sense operation of medical wire harness processing and causes of failure

Purchasing personnel should have a basic understanding of medical wiring harness now, so that they can better select high-quality wiring harness processing products when purchasing medical wiring harness. In fact, the wiring harness is the connecting part used to connect various parts of the electrical appliances, which can also be called the connecting line. The wiring harness is generally composed of wires, wiring terminals, insulating terminals, insulating sheaths and some insulating wrapping materials. The use of electrical equipment is usually different specifications, different colors of wiring harness in a reasonable design to work together, so that the various components of the equipment work together. General knowledge of wire harness processing of 1、: 1) the current loaded by different parts inside the automobile electrical equipment or industrial equipment is different, so the sectional area specifications of the wire are different at present; 2) A large equipment requires a large amount of harnesses, so it is normal to distinguish the harnesses for the convenience of maintenance. Generally, the harnesses used in different places are of different colors, and the harnesses are marked on the current diagram of the equipment; 2. Causes of harness faults: the harness faults include: open circuit, grounding, short circuit and poor contact of connectors; The causes of harness faults are as follows: 1. The harness has been used beyond its service life. During long-term use, the harness has problems such as aging, insulation layer cracking, and significant decrease in mechanical strength. The harness is prone to open circuit, grounding, and short circuit. 2. When the electrical equipment has faults such as overload, short circuit, and grounding, the harness will also be affected and cause harness faults. When the 3、 is maintaining the equipment, it is easy for metal objects to crush the wire harness and break the insulation layer of the wire harness if they are not careful. In addition, the improper position of the wire harness, the wrong connection of the lead position of the electrical equipment, the reverse connection of the positive and negative leads of the battery, and the disorderly connection and cutting of the wire harness when repairing the circuit failure will cause the wire harness failure.
