There are some factors that affect the contact resistance and reliability of RJ45 connector PIN pin:

(1) RJ45 network connector contact material

RJ45 connector technology conditions for different material production of the same specifications inserted into the contact parts, the provisions of the different contact resistance assessment index. Rapid separation of environment resistant RJ45 connector general specification for GJB101-86, diameter 1mm plug-in contact resistance, copper alloy is less than or equal to 5m, less than 15m ohm iron alloy.

(2) the surface of the surface of the connector on the RJ45 network

The surface of the RJ45 connector contact surface is a force that is produced and is perpendicular to the surface of the contact surface. With the increase of vertical pressure, contact area and micro quantity increase gradually, and contact points from elastic deformation to plastic deformation. As the concentration resistance decreases, the contact resistance decreases. Contact positive pressure mainly depends on the geometry and material properties of the contact parts.

(3) the surface morphology of the connector on the RJ45 network

The surface morphology includes the shape and the environment state of the connector contact. The contact surface may be due to dust, oil, etc. on the surface of the contact surface, which is easy to be embedded in the contact surface. Two is due to the physical adsorption and chemical adsorption of the formation of the film, the surface of the contact surface is mainly chemical adsorption, it is in the physical adsorption of the time after the migration. Therefore, for some high reliability requirements of the product, such as the use of electrical connectors must be clean assembly production conditions, improve the cleaning process and the necessary structural sealing measures, RJ45 connector use units must have a good storage and use of operating conditions.
