Protective measures required for wire harnesses

The maintenance of the wire harness requires the following considerations: one is the selection of the data of the wire harness itself, the other is the maintenance of the wire contacts in the wire harness, and the third is the maintenance of the hole terminals in the wire harness. The following Huichengyuan explains how to better maintain the wiring harness through these aspects. Wire harness information selection Wire harnesses are generally copper multi-core flexible wires, and there are also silver-plated wires. In many cases, a thin layer of high-conductivity silver is plated on the surface of the copper wire to improve conductivity. The most important requirement is based on the maximum current of the wire to select the appropriate wire diameter or cross-sectional area. In addition to the wire diameter of the electronic wire, the environment and function of the wire harness should also be considered. For example, the working environment of the engine is harsh, high-temperature environment, and there are many corrosive gases and liquids. Therefore, when selecting wires, wires that are resistant to high temperatures, corrosion, friction, and vibration are required. However, the types of wires are complicated, and each country has different classifications, different points of note, and different manufacturing standards. In production, abs wiring harness processing factories need to select electronic wires according to the detailed working environment and detailed requirements of abs wiring harnesses. Commonly used wires with PVC insulation are wires.

Maintenance of wire contacts in wiring harnesses The connection points between wires in wiring harnesses are called wiring harness contacts. Contacts are commonly found in instrument wiring harnesses, car sound wiring harnesses, cabin wiring harnesses and air-conditioning wiring harnesses. Signal transmission between switches and multiple electrical appliances can be realized through contacts, because it is necessary to adopt effective methods. Generally, after the contacts are connected, the copper wire core of the conductor is exposed, which is simply oxidized. Moreover, multiple contacts are wrapped in the wire harness at the same time, simply forming the connection between the contacts, causing the short circuit of the line, and in severe cases, it will cause the phenomenon of car burning. Therefore, the wiring harness contacts must be maintained with data with good insulation function. When used in different working environments, the contact bandaging materials are also different. PVC tape is generally used in wiring harness contacts that are less affected by the environment, such as instrument wiring harnesses, ceiling wiring harnesses, body wiring harnesses, 4-door wiring harnesses, air-conditioning wiring harnesses and other indoor wiring harnesses. Such materials are used to bandage contacts. The contacts between the front cabin wiring harness and the engine wiring harness are generally wrapped with double-layer heat-shrinkable tubes, which are waterproof, high temperature resistant and wear-resistant, but the cost is higher than that of adhesive tape.
