why use a car connector? what are its basic performance

　what is a car connector?

automobile connector, i.e. CONNECTOR。 it is also called automotive connectors, plugs and sockets in china.

automobile connectors generally refer to electrical connectors. that is, the device connecting two active devices to transmit current /signal. its function is very simple: it builds a communication bridge between blocked areas in the circuit or between isolated circuits, so that the current flows and enables the circuit to achieve predetermined functions. connectors are indispensable components in electronic devices. when you observe along the path of current flow, you will always find that there are one or more connectors. the basic performance of automotive connectors can be divided into three categories: mechanical properties, electrical properties and environmental properties.

why use a car connector?

imagine what would happen if there were no connectors? at this time, conductors should be used between the circuits. **if the electronic device is to be connected to the power supply, the connecting wires must be fixedly connected to the electronic device and the power supply through some method. (for example, welding )。in this way, both production and use bring many inconveniences. core advantages: simple assembly process, easy mass production, easy maintenance and replacement, easy update and upgrade, etc.

basic performance of automotive connectors?

the basic performance of connectors can be divided into three categories: mechanical properties, electrical properties and environmental properties.

1.mechanical properties:

spreading force---segmented into insertion force and pulling force

connector plugging force and mechanical life and contact structure (positive pressure )contact area coating quality (sliding friction coefficient )and the dimensional accuracy of contact parts (alignment degree )related.

2.electrical performance:

contact resistance – high-quality electrical connectors should have low and stable contact resistance. the contact resistance of the connector ranges from a few milliohms to tens of milliohms.

insulation resistance - an indicator to measure the insulation performance between contacts of electrical connectors and between contacts and housings, ranging from hundreds of megohms to several gigaohms. electrical resistance strength, or voltage withstand voltage and medium voltage withstand voltage - is the ability to withstand the rated test voltage between the connector contacts or between the contacts and the housing.

3.environmental performance:

common environmental properties include temperature resistance, humidity resistance, salt spray resistance, vibration and shock resistance, etc.

other environmental properties also have sealing properties (air leakage, liquid pressure )、liquid impregnation (ability to resist vice-abuse to specific liquids )、low pressure, etc.
