Abstract
The utility model relates to a universal circuit breaker comprising a contact system coupling plate and a plurality of soft coupling lines connected with the coupling plate, wherein one end of the coupling plate, connected with all the soft coupling lines, is provided with corresponding round holes for the insertion of ends of all the soft coupling lines, connected with the coupling plate, for fixed connection; and one side edge of the coupling plate, adjacent to the corresponding round holes, is provided with a groove for extruding all the round holes and fixedly connecting all the soft coupling lines. Compared with the prior art, the universal circuit breaker compresses the working procedures, simplifies tooling, has simple and convenient operation, good consistence, stability and reliability, thus reducing working time, reducing the processing period and cost, and meeting the requirements of product standard in the industry of the electric appliance. In addition, as the coupling work of the contact system and the soft coupling lines of the large universal circuit breaker can be realized by only adopting a small-tonnage universal hydraulic machine and a special die, the equipment is saved and the energy consumption is reduced. The universal circuit breaker can be applicable to the processing work of the contact systems of all the universal circuit breaker products with larger specifications.
Description
Technical field
The utility model belongs to a kind of circuit breaker, particularly relates to a kind of omnipotent breaker.
Background technology
Low-pressure electronic equipment product---the key component in the omnipotent breaker is a contact system at present, the binding of its joint cover and flexible connection, different producers adopts different connecting structures according to oneself technology, equipment, fresh water (FW) equality condition, and main concentrating to following two kinds: a kind of is welding manner.What most of producer adopted is the method, also is traditional method, but along with the continuous expansion of product specification, the raising of current class, size, the sectional area of parts continue to increase, and therefore require corresponding welding equipment also will increase.Binding with TW30-2000 specification contact is an example, needs 500 kilovolt-amperes DC welder, and correspondingly the ability of electric power system also requires to increase thereupon, and it all is huge purchasing the expense of relevant device and the consumption of electric power.Another kind is a cold extrusion method.There is part producer to adopt the cold extrusion linking method: on joint cover, to mill out elongated slot, the flexible connection end is welded into the rectangular weldering knot of correspondingly-sized, and the flexible connection weldering is tied in the joint cover elongated slot of packing into, with mould riveting is split on the joint cover top, again with mould with the top compacting, link closely to reach.The method operation is complicated, needs the amount of labour of consumption very big.
Summary of the invention
The utility model provides the binding technology of a kind of joint cover and flexible connection simple for solving the technical problem that exists in the known technology, the omnipotent breaker that energy consumption is lower.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it includes contact system joint cover and many flexible connection lines that link to each other with described joint cover, on described joint cover and a end that described each flexible connection line is connected, there is an end that described every flexible connection line can be linked to each other with described joint cover to insert the corresponding circular hole of the usefulness that is connected, on a side of the joint cover adjacent, is useful on the be connected groove of described each flexible connection line of described each circular hole of extruding with described each corresponding circular hole.
The utility model can also adopt following technical scheme:
Deflection after described each circular hole is extruded is the 5-10% of described circular hole area.
Advantage and the good effect that the utlity model has are: owing to adopted at contact system joint cover and flexible connection line and connect an end perforate, the flexible connection line inserted in the hole that described joint cover opens and the flexible connection line is pushed with cold extrusion method again and be fixed in the hole that joint cover opens.Compared with prior art on processing technology, compress operation, simplified frock, made simple, convenient, high conformity, reliable and stable, thereby reduced machining period, reduced process-cycle and cost; With 1600 amperes of specification omnipotent breakers is example, and carry out temperature rise contrast experiment checking: the temperature rise of welding method is greater than 80 °, and linking method temperature rise of the present utility model has only 60 °, has satisfied the requirement of product standard in the electrical apparatus industry fully.Specified short time withstand current industry standard requires to apply the electric current of 6.5kA on circuit breaker, do not allow Anywhere to disconnect within 1 second, adopts the utility model connecting structure once to pass through smoothly, does not find any fault.This method is owing to only need to adopt the general hydraulic press of little tonnage in addition, can realize the connection work of the contact system joint cover and the flexible connection line of large-scale formula circuit breaker having reduced energy consumption again by particular manufacturing craft.The utility model goes for the contact system processing work of all big specification omnipotent breaker products.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, 2, 3, on the joint cover 1 in the omnipotent breaker contact system, an end that is connected with flexible connection line 2 has can be with every flexible connection line 2 and joint cover 1 circular hole 4 of logotype mutually.The weldering knot of every flexible connection line 2 inserts in the circular hole 4 corresponding on the joint cover 1.Being useful on each circular hole 4 of extruding on the upper side edge of the adjacent joint cover 1 of corresponding circular hole with each 4 makes its distortion and then each flexible connection line 2 is reinforced groove 3 on joint cover 1.With 1600 peace omnipotent breakers is example, and the deflection after circular hole 4 is extruded promptly can be 5%, 8% of circular hole area and also can be 10%.
Claims (2)
1. omnipotent breaker, it includes contact system joint cover and many flexible connection lines that link to each other with described joint cover, it is characterized in that: on described joint cover and a end that described each flexible connection line is connected, have an end that described every flexible connection line can be linked to each other with described joint cover to insert the corresponding circular hole of the usefulness that is connected, on a side of the joint cover adjacent, be useful on described each circular hole of extruding and produce the groove of distortion with described each flexible connection line that is connected with described each corresponding circular hole.
2. omnipotent breaker according to claim 1 is characterized in that: the deflection after described each circular hole is extruded is the 5-10% of described circular hole area.
