A general term for connecting two or more circuit devices. The signal connector price device is an electromechanical component, generally working in pairs, divided into plug (male), socket (female), plug English plup (or male, header); socket (female) English Receptanle or Socket ,jack,female.
It completes the connection and disconnection of electrical appliances through certain mechanical actions. Its main functions are:
Transmitting or transmitting electrical energy
Turn on the circuit or cut off the circuit
1, mechanical parameters
Insertion force is an important mechanical property to measure connector performance. The insertion force is divided into the insertion force and the extraction force (or separation force), and the requirements of the two are different. From the point of view of use, the insertion force requirement should be as small as possible, and the pull-out force should not be too small, otherwise the reliability of the contact will be affected.
Mechanical life is actually a durability index. It is a cycle of one insertion and one extraction to determine whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and removal cycle. .
It is related to the contact structure (positive pressure), the coating quality of the contact portion (sliding friction coefficient), and the dimensional accuracy (alignment) of the contact arrangement.
2, electrical parameters
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.
Depending on the material and cross-sectional area of the terminal, the larger the cross-section, the smaller the impedance per unit length, and the less heat generated by the current, the smaller the terminal temperature rise, and the larger the current can be conducted.
An indicator of the insulation properties between electrical connector contacts and between the contacts and the outer casing, in the order of hundreds of megaohms to several gigaohms.
Also known as withstand voltage, dielectric withstand voltage, is the ability to characterize the rated test voltage between connector contacts or between contacts and housing.
