The fundamental function of RJ45 network adapter connector knowledge can be divided into three categories: mechanical electrical function, function and environment function. Another important function is the mechanical adapter. His mechanical life is actually a kind of mechanical durability (durability), in the national standard GB5095 called it the operation of machinery. Is taking a stab and a pull out for a cycle, with the rules of the plug adapter can normally complete the cycle after its cohesive function (such as touch resistance) as the basis for evaluation.

1 mechanical function of cohesion, force is the primary mechanical function. Plug into pierce force and pull-out force (also known as the pullout strength of parting force), the request is not the same. The maximum pierce force and the minimum parting rules in the relevant standard, which indicates that, from the use of perspective see, Pierce force to small (and low pierce force LIF and non structural stab ZIF), and if the parting force is too small, it will affect the reliability of touch. Connector plug and mechanical life and touch structure (positive pressure size) touch parts coating quality (coefficient of sliding friction) and touch parts size precision display (alignment).

2 the primary electrical function of the electrical connector includes the touch resistance, the insulation resistance and the electrical resistance.

The electric connector with a high quality of touch resistance should have low and stable touch resistance.

The insulation resistance measuring insulation function between touch and touch between the part and the shell target electrical connectors, ranging from the order number of megabytes to several European begohm.

The resistance to electrical strength, or dielectric breakdown voltage, is the ability to characterize the ability to withstand the additional experimental voltage between the connector's touch parts or between the touch parts and the housing.
