Problems solved by technology

However, due to the large number of different interconnecting components, the quincunx contact assembly has an even more complex structure than previously discussed quincunx contact assemblies
Furthermore, the large number of contact fingers means that a larger surface has to be processed for the electrical conductivity requirements; moreover, this means an increase in manufacturing costs, which makes the quincunx contact assembly rather expensive

Embodiment Construction

[0027] With reference to the accompanying drawings, there is shown a connecting device 1 which is particularly adapted, in a non-limiting manner, for use in the field of medium voltage, for the purposes of this application the term "medium voltage" refers to applications ranging from 1 kV up to several Ten kV (eg 52kV). The connection device 1 is suitable for being mounted to a pole terminal 6 of a switchgear 30 , for example a circuit breaker 30 , in particular a withdrawable circuit breaker 30 accommodated in the switch cabinet 2 . The circuit breaker 30 is of the following type in a non-limiting manner: the circuit breaker is supported by trolleys which are movable from an withdrawn position relative to the switch cabinet 2 to an inserted position in the switch cabinet 2 In the position, the movable conductive terminal is disengaged from the fixed conductive terminal (such as the contact post element 4 ); in the inserted position, the movable conductive terminal is connecte...

Abstract

A connecting device for a switchgear (2), said connecting device comprising: - a quincunx-shaped tuft part (3) for electrical engagement with a contact post element (4); - a mounting end part (5), the mounting end part for mechanical connection to the pole terminal (6); - and the conductive transmission part (7), the conductive transmission part for the current transmission from the contact post element (4) to the A pole terminal (6), each of said conductive transfer portions (7) extends from a respective quincunx-shaped tuft portion (3) to a respective base portion (8) of said mounting end portion (5). Said quincunx-shaped tuft portions (3) and respective conductive transfer portions (7) and respective base portions (8) are integral with each other to define respective one-piece portions (9).

Description

technical field [0001] The present disclosure relates to a connection device for a switchgear, in particular to a connection device suitable for connecting a movable conductive terminal of a switchgear (especially a circuit breaker) to a fixed conductive terminal of a switchgear. Background technique [0002] In the medium voltage field it is known to use a tulip-contact-assembly for electrically connecting movable conductive terminals provided on a pull-out circuit breaker to a switchgear Secure the conductive terminals. [0003] The known quincunx contact assembly comprises a support frame defined by a pair of star-shaped flanges spaced parallel to each other and fixed to each other by rod elements. The quincunx contact assembly comprises a plurality of distinct and separate contact fingers which rest into socket portions formed on a star flange and are formed by a ring extending around the central axis of the support frame. The coil spring is pressed against the seat po...
