99% of people do not know the male female connector plugging force of the four big pits, plugging force is a key indicator of the male female connector, directly related to the performance and use of the connector, and the impact of the connector plugging force of the four main factors.
First, contact pressure
contact pressure is an important factor affecting the male female connector contact resistance control plugging force
Second, contact keys
the second number of contact keys contact keys the more the number of plugging force pulling force it is greater The more the contact pressure increases, the greater the plugging force will lead to the plug is not easy to plug and unplug.
Third, contact key with the error
the third contact key with the error, male female connector assembly errors and the existence of manufacturing errors lead to contact keys in the plugging process is prone to pin skew phenomenon, that the pin and jack ground between the additional squeezing pressure.
Fourth, friction force
the fourth surface friction coefficient male female connector friction force The size of the frontal pressure between the contact surface and the coefficient of friction, the greater the surface roughness rubbing force will constitute wear and tear on the contact key, but now the WEICHAT on the production of industrial male female connectors, the choice of copper alloy as the material of the contact parts and supplemented by nickel-base gold plating process, fully equipped to meet the corresponding standard requirements of plugging, mechanical plugging life of not less than 1000 times.
