Electrical performance test of RJ45 network connector includes voltage resistance test, contact resistance test, insulation resistance testing, conduction test and fracture test and pressure test, the test results and the electrical performance of RJ45 connector is directly related to the quality, the specific requirements are as follows:

(1) withstanding voltage, also known as voltage withstanding and dielectric withstanding voltage, voltage withstand test is the test of the withstand voltage capability of various electrical installations, insulation materials and insulation structures. The process of applying high voltage to insulating material or insulation structure is called pressure resistance test without damaging the properties of insulating materials. The basic rule is: two times the working voltage of the tested object plus 1000V as the standard voltage of the test, the test voltage of some products may be higher than the specified value. Generally speaking, the main purpose of withstanding voltage test is to check the ability of insulation to withstand working voltage or overvoltage, and then test whether the insulation performance of product equipment meets the safety standard.

(2) the resistance presented to the conductor is called the contact resistance, and the contact RJ45 connector should have a low and stable contact impedance. The contact resistance of connectors is from several milli to tens of ohms, and its resistance is mainly influenced by contact materials, positive pressure, surface state, voltage and current.

(3) to measure the resistance between the contacts between the RJ45 connector and contact with the shell insulation performance index of insulation, ranging from the order number of megabytes to several European begohm, mainly affected by environmental temperature and humidity, test time and line etc..

(4) the conduction test is to test the electrical integrity of RJ45, and to detect whether RJ45 meets the requirements of the corresponding specifications.

(5) other electrical properties.

RJ45 network connector, EMI leakage attenuation parameter is the embodiment of RJ45 network connector electromagnetic interference shielding effect, its frequency test range is generally 100MHz~10GHz.
