Through the combination of different terminals, the three-phase three wire system, three-phase four wire system and other wiring modes can be formed.
【技术实现步骤摘要】
一种电能计量专用接线盒
本专利技术属于电能计量接线领域,具体涉及一种电能计量专用接线盒。
技术介绍
在电能计量接线领域,电能计量专用接线盒是实现电气连接、电流测试的重要器件之一,现有电能计量专用接线盒主要包括一体化的盒体、装配在盒体内的导电管,压接螺钉,分断用的连接片,以及盒盖组成。但是,传统结构的电能计量专用接线盒由于是采用一体化的盒体,可扩充性差,用户要求不一样的接线位数时,需要重新制作模具,成本高,不灵活,导电管采用铜条切断、钻孔方式制成,铜材用量大,加工费时,成本高。电流测试时没有专门的测试孔,测试不方便。
技术实现思路
针对上述不足,本专利技术提供一种模块化的电能计量专用接线盒。本专利技术是通过这样的技术方案来实现的:一种电能计量专用接线盒,包括盒体、装配在盒体内的普通端子,电流端子,可滑动断开的联络件,防止窃电的防盗螺钉,以及透明盒盖组成。盒体两侧设有方孔,可供接线使用,盒体内设有一条及以上的筋,起功能分区,以及增加盒体的强度作用。盒体内装有两种接线端子,一种是普通端子,一边进线一边出线,中间有可供连接的圆孔,端子间装有可滑动断开的联络件,供测试使用,导电片为片状,通过冲压加工的方式得到,节约材料和加工工时。另外一种端子是电流端子,它不仅有接线的功能,而且还有分断、测试的功能,断开和接通有颜色分别显示,导电片和测试孔为一体成型的方式,节约材料和工时。普通端子和电流端子有联接用的孔和拼装销,几个端子可并在一起装入盒内,两种端子的两侧都有弹性分支,装入的时候分支向内收,顺利装入,装入后分支弹开,顶住方孔的上沿,端子就不会掉出盒体。盒体上面配有透明盒盖, ...
