sliding metal contact

Meanwhile, the cladding of formation between metal vapor and copper-matrix can reduce contact resistance at the contact zone and the probability of electric arc occurring, and thus reduce electrical sliding wear rate of the contact strip.

同时金属蒸气与铜基体形成的合金覆层降低了接触区的接触电阻，减小了电弧产生的几率，从而使得滑板的载流磨损率降低。

Sliding head D can slide along the metal bars, with good contact resistance wire, changing its location can change the AC ( or BC) resistance.

滑动头D可沿金属杆滑动，与电阻丝接触良好，改变其位置就可以改变AC（或BC）电阻。

The conductive metal strip used as a conductive contact surface is always kept full sliding contact with the electric brush, so that the utility model has favorable power supply effect.

由于用作导电接触面的导电金属条与电刷始终能保持全面滑动接触，所以供电效果好。
