Why use automotive connectors What are its basic properties?

Automotive connectors, that is, CONNECTOR, also known as automotive connectors, plugs and sockets. Automotive connectors generally refer to electrical connectors. It is a device that connects two active devices to transmit current/signal. Its role is very simple: in the circuit is blocked or isolated between the circuit, set up a communication bridge, so that the current flow, so that the circuit to achieve the intended function. Connector is an indispensable part of electronic equipment, along the current flow path observation, you will always find one or more connectors. The basic performance of automotive connectors can be categorized into three main groups: namely, mechanical performance, electrical performance and environmental performance.

Why use automotive connectors? Imagine what would happen if there were no connectors? Circuits should be permanently connected to each other with conductors, such as electronic devices to be connected to the power supply, the connecting wires must be connected to the electronic device and the power supply through some kind of method of fixing (e.g., soldering). In this way, both for the production and use, have brought a lot of inconvenience. Core advantages: simple assembly process, easy mass production, easy maintenance and replacement, easy to update and upgrade. The basic performance of automotive connectors? The basic performance of the connector can be divided into three categories: mechanical properties, electrical properties and environmental performance. 1.Mechanical properties: broadcast pulling force - divided into the insertion force and pull-out force connector insertion and pull-out force and mechanical life with the structure of the contact parts (the size of the positive pressure) contact parts of the plating quality (coefficient of sliding friction) as well as the contact parts of the arrangement of the dimensional accuracy (degree of alignment). 2.Electrical properties: contact resistance - high quality electric Connectors should have a low and stable contact resistance. Connector contact resistance from a few milliohms to tens of milliohms. Insulation resistance - a measure of the electrical connector between the contact parts and the contact parts and the shell of the insulation between the indicators, the order of magnitude of hundreds of megohms to thousands of megohms ranging. Resistance or voltage, dielectric withstand voltage - is characterized connector between the contacts or contacts and the shell between the ability to withstand the rated test voltage.3. Environmental performance: common environmental performance, including temperature, humidity, salt spray resistance, vibration and shock and so on. Other environmental properties are sealing (air leakage, liquid pressure), liquid impregnation (the ability to resist vices of specific liquids), low air pressure.
