插座插套的磨损因素研究

Research of Socket-Contacts of a Socket about Abrasion Factor

插套是插座的核心部件,其性能直接影响到插座的寿命和安全。插套的一个最主要性能是拔出力,必须在规定范围内,低于这个范围,因难以夹住插头,则判定失效。拔出力与插套的材料、造型、尺寸相关。但随着使用次数的增加,插套内侧会被磨损,从而使得拔出力降低。如何延缓磨损速度,是摆在插座生产厂家面前的一个课题。

Socket-contact is the key component of a socket,it's performance influences life and security of the socket.Pullout force which is the main performance of socket-contact,must be within specified scope.When pullout force is lower than specified scope,the plug can not be clamped by socket-contact,so the socket is determined invalid.The pullout force is related with material,shape and size.Abrasion will appear on the inside of socket-contacts,along with the number of uses has been increased,while the pullout force will reduce.How to delay the speed of abrasion,is an important topic to the socket manufacturer.
