Abstract

本实用新型涉及一种高可靠导通的拔插触点，包括二次线插拔式触点，其特征是，所述的二次线插拔式触点包括静触点以及与静触点线接触的静触点座，动触点和与动触点线接触的动触点座，动触点四周均匀涂敷石墨层，动触点与静触点线接触时，石墨层与静触点进行线接触。本实用新型随着拔插次数的增加，石墨层与静触点铜材质更加吻合，接触的更好。同时石墨与铜的电极电位接近，消除了动静触点间的电化学腐蚀，也消除了直流电对触点的腐蚀，达到可靠性导通的目的。

Description

高可靠导通的拔插触点
技术领域
本实用新型涉及一种高可靠导通的拔插触点。
背景技术
现一般NNS型导配电柜上二次线拔插式触点采用的是线接触式，并且表面一般涂抹防腐凡士林膏。当此触点应用到弱电信号直流电的情况下，经常出现接触不良的现象。一般此弱信号直流电要求高可靠性导通，而对载流量要求不高。
实用新型内容
根据以上现有技术中的不足，本实用新型要解决的技术问题是：提供一种可以克服上述缺陷，提供高可靠性导通效果的插拔式接触点。
本实用新型所提供的高可靠导通的拔插触点，包括二次线插拔式触点，其特征是，所述的二次线插拔式触点包括静触点以及与静触点线接触的静触点座，动触点和与动触点线接触的动触点座，动触点四周均匀涂敷石墨层，动触点与静触点线接触时，石墨层与静触点进行线接触。
所述的石墨层厚度为0.2-1mm。
本实用新型所具有的有益效果是：随着拔插次数的增加，石墨层与静触点铜材质更加吻合，接触的更好。同时石墨与铜的电极电位接近，消除了动静触点间的电化学腐蚀，也消除了直流电对触点的腐蚀，达到可靠性导通的目的。
附图说明
图1是本实用新型结构示意图；
图中：1、动触点；2、静触点；3、动触点座；4、静触点座；5、石墨层。
具体实施方式
下面结合附图对本实用新型的实施例做进一步描述：
如图1所示的高可靠导通的拔插触点，包括二次线插拔式触点，所述的二次线插拔式触点包括静触点2以及与静触点2线接触的静触点座4，动触点1和与动触点1线接触的动触点座3，动触点1四周均匀涂敷石墨层5，动触点1与静触点2线接触时，石墨层5与静触点2进行线接触。

Claims (2)
