About the basic nature of the connector

Connector performance is divided into three main properties: mechanical properties, electrical properties and environmental performance.

These three properties directly affect the stability of the product in the production and use. So they are indispensable, even the process requirements are also very high.

1, mechanical performance in terms of connection function, insertion force is an important mechanical performance. Insertion force is divided into insertion force and pull-out force, which have different requirements. Relevant standards have Z large insertion force and Z small separation force provisions, indicating that the insertion force should be small, the separation force is too small will affect the reliability of the contact.

Another important mechanical performance is the mechanical life of the connector. Mechanical life is actually an indicator of durability, known as mechanical operation in the national standard GB5095. An insertion and removal as a cycle, after the specified insertion and removal cycle to determine whether the connector can normally complete its connection function.

Insertion force and mechanical life with the contact structure of the contact part of the coating quality and contact arrangement of the size accuracy.

2, electrical performance connector's main electrical properties include contact resistance, insulation resistance and electrical strength.

① Contact resistance High-quality electrical connectors should have a low and stable contact resistance. Contact resistance of the connector from a few milliohms to tens of milliohms ranging.

② insulation resistance is a measure of electrical connector contacts and between the contacts and the shell insulation performance indicators, the order of magnitude from hundreds of megohms to thousands of megohms ranging.

③ Dielectric strength, or voltage resistance, dielectric withstand voltage, is a characterization of the connector between the contacts or between the contacts and the shell to withstand the rated test voltage capacity.

④ Other electrical properties.

Electromagnetic interference leakage attenuation is to evaluate the connector's electromagnetic interference shielding effect, and electromagnetic interference leakage attenuation is to evaluate the connector's electromagnetic interference shielding effect, generally tested in the frequency range of 100MHz ~ 10GHz.

3, environmental performance Common environmental performance includes temperature resistance, humidity resistance, vibration resistance and impact resistance.

① Temperature resistance

② Humidity resistance

③ Salt spray resistance

④ Vibration and shock

⑤ Other environmental performance.
