用于真空断路器的极单元
Abstract:
本发明涉及一种用于真空断路器的极单元(1)，具有金属的极支座(2)和外部的绝缘体(4)，其中该绝缘体(4)利用多个连接螺栓(5，6，7，8)固定在所述极支座(2)的保持元件(2.1)上，其中在所述极支座(2)和连接螺栓(5，6，7，8)之间分别形成电连接(10)。按照本发明，所述电连接被构造为由导电线构成的弹性的蝶形弹簧(10)，其中，所述蝶形弹簧(10)具有与相应的连接螺栓(5，6，7，8)电接触的开口的接触环，和与所述接触环相连的两个边脚，其分别通过接触柱与所述极支座(2)电接触。
Abstract(English):

The invention relates to a pole unit (1) for a vacuum circuit breaker having a metallic pole mount (2) and an outer insulating body (4), wherein the insulating body (4) is attached by means of a plurality of connecting screws (5, 6, 7, 8) to holding elements (2.1) for the pole mount (2), wherein a conductive connection (10) is in each case formed between the pole mount (2) and the connecting screws (5, 6, 7, 8). According to the invention, the respective conductive connection is formed by a resilient spring clip (10) composed of electrically conductive wire, wherein the spring clip (10) has an open contact eye, which makes electrical contact with the corresponding connecting screw (5, 6, 7, 8), and has two limbs which are connected to the contact eye and each make electrical contact with the pole mount (2), via a contact pin.
