(1) the data of the touch

The conditions of different RJ45 network connector technology made with standard inserted touch, touch is not the same as the target resistance check rules. Rapid separation environment resistant RJ45 network standard GJB101-86 connector general rules, diameter is inserted a touch touch the resistance of 1mm copper alloy is less than or equal to 5m, less than 15m ohm iron alloy.

(2) the surface of the touch is straight.

RJ45 the surface of the connector of the connector is the appearance of a touch of the touch of the surface and the force that is straight to the surface. Direct pressure essays add, touch points number and area gradually add together, touch points from elastic deformation to plastic deformation. Because have resistance gradually decreases, and the touch resistance decrease. The touch of a positive pressure depends on the geometry and the material function of the touch.

(3) appearance

The shape of the surface of the shape and the location of the environment, the surface of the touch may be due to dust, rosin, oil, etc. in the contact surface of the surface of the film is more relaxed, which is easy to be embedded in the surface of the micro concave hole, the touch area is reduced, the touch resistance increases, and very unstable. Two is because the physical adsorption and chemical adsorption of the contaminated membrane, the metal surface is the first chemical adsorption, it is in the physical adsorption and the seizure of the electron. Therefore, for some of the high reliability of the products, such as the use of electrical connectors must have a clean production environment conditions, improve the clean technology and the necessary structural seal approach, RJ45 network connector use units must have a good storage and use of operating conditions.

(4) the use of voltage

RJ45 network connector use voltage to reach a certain threshold, will make the film is broken down, and make the touch resistance rapidly reduced. But because the thermal effect accelerates the chemical reaction of the adjacent region of the film, the film has a certain correction effect. So the emergence of nonlinear resistance. In the vicinity of the threshold voltage, the voltage drop of the small fluctuations can cause the current may be twenty times or several times to change the range. To make a great change in the touch resistance, not to understand the situation will be in the test and the use of touch parts of the fault.
