AI Technical Summary

Problems solved by technology

The conductive group in this structure is the conductive elastic contact, which is composed of a conductive cylinder seat, a conductive cap and an extension spring. Its structure is complex and the cost is high

In addition, due to the sliding fit between the conductive cap and the inner cavity of the conductive cylinder seat, when dirt accumulates in the gap between the two, it is easy to get stuck; or, when the conductive group is applied to other high-power electric facilities, the conductive cap and the conductive cylinder seat The fit gap is prone to sparking and melting, which makes the two connected together, loses elasticity, reduces the compression degree when it contacts with other conductive contacts, and weakens the conductive effect

Furthermore, because the conductive group is in a closed structure, its heat dissipation effect is poor, so that the temperature rise of the conductive group is serious

In addition, the sliding fit between the conductive cap and the conductive cylinder seat causes irregular shaking of the stretching spring during telescopic movement. Therefore, after the conductive group is used for a long time, the mating surface between the conductive cap and the conductive cylinder seat has irregular wear , so that the matching gap between the conductive cap and the conductive cylinder seat increases, so that the conductive effect is weakened; in addition, although the conduction between the conductive cap and the conductive cylinder seat can be conducted through the stretch spring, the conductivity of the metal material for the stretch spring is not good. Good, the corrosion of the conductive coating on the surface of the stretch spring makes the conductivity of the conductive group weaken quickly, especially in the field of high-power (strong current) electric power, and occasions that require long-term opening and closing work, which can reflect the above The conductive group has a shorter service life
