Electrical performance of RJ45 connector

The main electrical properties of the electrical performance connector include contact resistance, insulation resistance, and electrical resistance.

The electric connector with high contact resistance should have low and stable contact resistance. The contact resistance of the connector is from a few cents to a dozen.

The insulation resistance of the insulation performance indicators measure between the electrical connector contacts and contact with the shell, the order of the number of megabytes to several begohm ranging from europe.

The anti electric strength, or the dielectric breakdown voltage, is the ability of the test voltage to be able to withstand the rated test voltage between the connector's contact parts or between the contact parts and the casing.

Mechanical properties of RJ45 connector

In terms of mechanical properties, the plug is an important mechanical property. Insertion force is divided into insertion force and pull out force (pull out force, also known as separation force), the requirements of the two are different. In the relevant standard of the maximum insertion force and the minimum separation force, which shows that from the perspective of use, the insertion force to be small (which has a low insertion force LIF and no insertion force ZIF structure), and if the separation force is too small, it will affect the reliability of contact.

Another important mechanical performance is the mechanical life of the connector. Mechanical life is actually a durability (durability) index, in the national standard GB5095 it is called mechanical operation. It is a loop that is inserted at one time and one at a time, in order to complete the connection function (such as the contact resistance value) as the basis for the evaluation. The insertion force and mechanical life of the connector are related to the coating quality (sliding friction coefficient) of the contact part of the contact part (positive pressure) and the arrangement of the contact pieces (alignment).
