Description

Multipurpose low voltage short connector
Technical field
The present invention relates to a kind of short connector, particularly a kind of Multipurpose low voltage short connector.
Background technology
Low-voltage circuit breaker is that one not only can be connected and disjunction normal duty electric current and overload electric current, can also connect the device for switching with disjunction short circuit current.Low-voltage circuit breaker except rising except control action, also has certain defencive function in circuit, as overload, short circuit, under-voltage and earth leakage protective etc.At present, China's low-voltage network all widely uses low-voltage circuit breaker from the distribution station of power supply before the ammeter of customer side.
Low-voltage circuit breaker mainly contains following characteristics in the application, and one is that low tension switch is maximum with mold cased circuit breaker usage quantity, kind nearly thousands of kinds, and different manufacturers, variety classes construction of switch pattern, size exist obviously difference; Two is that low-voltage moulded case switch is mainly arranged in GGD type, GCK type AC low-tension switch cubicle and box change, adopts hard copper, duralumin busbar and circuit to overlap.This type of switch cubicle (change) generally has compact conformation, floor space is little, feeder number is more feature, these features determine between the switch phase and phase of the same circuit, the installing space of the switch of different circuit and switch, busbar and busbar is very little, substantially between 2CM to 10CM.
Above switch application feature plays positive role in saving switch cubicle manufacturing dimension, minimizing floor space etc., but in switch operating maintenance, also bring an a series of difficult problem, mainly just there will be once faults such as occurring switching damage: one is that the inspection earthing line in single loop in space in narrow and small cabinet cannot be installed, and needs to expand power failure loop and area; Two is in replacing, the switch that of a great variety, size differs occurs that the spare unit switch not having same model is interchangeable often, other switches cannot substitute again, often to find and switch can be used to require a great deal of time, once cannot find, busbar continuation mode can only be changed, cause interruption duration to postpone at double.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and provide one namely can be used as rapid rush-repair telegram in reply effective means after different model, different size switch fault, the Multipurpose low voltage short connector of use also can be fixed as short circuit earth connection conductor wire end.
A kind of Multipurpose low voltage short connector, includes geometrical clamp, soft jumper, short circuit part,
Described geometrical clamp includes the fixture of conduction and the adaptor of conduction, described fixture is U-shaped structure, a side of U-shaped structure is provided with plural screwed hole, screwed hole is furnished with bolt, described adaptor is the adaptor of L-type, the adaptor of L-type and U-shaped structural mount with the use of, the minor face of L-type adaptor can be inserted in the U-type groove of U-shaped structural mount, in use, the long limit of L-type adaptor has that side of screwed hole towards U-shaped structural mount, the long limit of L-type adaptor is provided with plural connecting hole;
