Abstract
The utility model provides a kind of bus-bar connection structure of miniature circuit breaker, and main improvements exist, including breaker, bus-bar connection jaws, terminal screw, bus-bar；The breaker includes one or several breaker units；Multiple U-shaped lug plates are equipped on the downside of the bus-bar, each U-shaped lug plate connects one to one with multiple electric loops in bus-bar；It is respectively provided with a bus-bar connection jaws on the top of breaker, each breaker unit, terminal screw is set in bus-bar connection jaws；Corresponding handle hole is set on breaker unit shell on the outside of terminal screw.The utility model solves the problems, such as the bus-bar connection structure of present miniature circuit breaker in use so that wiring is more compact, is not take up the connection jaws of breaker.
Description
Technical field
The utility model is related to low-voltage electrical industry field, the bus-bar connection structure of especially a kind of miniature circuit breaker.
Background technology
The bus structures connection of existing miniature circuit breaker can occupy the connection jaws of breaker when using, it is difficult to realize one
A breaker multipole wire jumper.
Invention content
For the deficiencies in the prior art, the utility model provides a kind of bus-bar connection knot of miniature circuit breaker
Structure solves the problems, such as the bus-bar connection structure of present miniature circuit breaker in use so that wiring is more compact, is not take up open circuit
The connection jaws of device do not influence the connection function of independent breaker.The technical solution adopted in the utility model is：
A kind of bus-bar connection structure of miniature circuit breaker, main improvements exist, including breaker, bus-bar wiring
Mouth, terminal screw, bus-bar；The breaker includes one or several breaker units；
Multiple U-shaped lug plates, each U-shaped lug plate and multiple electric loops one in bus-bar are equipped on the downside of the bus-bar
One is correspondingly connected with；
A bus-bar connection jaws are respectively provided on the top of breaker, each breaker unit, in bus-bar connection jaws
Terminal screw is set；Corresponding handle hole is set on breaker unit shell on the outside of terminal screw.
Further, the breaker is 4P breakers, including four breaker units.
Further, the breaker is 3P breakers, including three breaker units.
Further, the breaker is 2P breakers, including two breaker units.
Further, the breaker is 1P breakers, including a breaker unit.
The utility model has the advantage of：The utility model by by bus-bar access breaker on bus-bar socket come
Wiring so that wiring is more simple in the case of the multigroup wire jumper of this needs, facilitates construction and maintenance work in the future.The bus-bar
Wiring construction is different from existing bus-bar type of attachment, the bus structures in the market and can be used alone, bus-bar not shadow
The normal wiring of breaker connection mouth is rung, it can be achieved that multiple breaker wire jumpers.
Description of the drawings
Fig. 1 is that the 4P breaker bus-bars of the utility model access schematic diagram.
Fig. 2 is schematic diagram after the 4P breaker bus-bars of the utility model access.
Specific implementation mode
With reference to specific drawings and examples, the utility model is described in further detail.
In the present embodiment by taking 4P breakers as an example, illustrate the bus-bar connection structure of miniature circuit breaker, 1P, 2P, 3P open circuit
The connection structure of device is identical；
The bus-bar connection structure of miniature circuit breaker, including 4P breakers 1, bus-bar connection jaws 2, terminal screw 3, confluence
Row 4；4P breakers 1 include four breaker units；
4 downside of the bus-bar is equipped with multiple U-shaped lug plates 401, each U-shaped lug plate 401 and multiple electricity in bus-bar 4
Air circuit connects one to one；Bus-bar 4 be used for the phase isopen or zero curve of multiple breakers is in parallel, such as by two open circuits
The A phase, B phase, C phase and zero curve of device are respectively connected with；
A bus-bar connection jaws 2, bus-bar wiring are respectively provided on the top of 4P breakers 1, each breaker unit
Terminal screws 3 are set in mouth 2；Corresponding handle hole 301 is set on the breaker unit shell in 3 outside of terminal screw；
When connection, in sequence by the bus-bar wiring on the insertion breaker unit of U-shaped lug plate 401 on bus-bar 4
Mouth 2, screws terminal screw 3, completes the installation of bus-bar one by one later.
This bus-bar connection structure can make wiring more compact, be not take up the connection jaws 5 of breaker, do not influence independent open circuit
The connection function of device.
It should be noted last that the above specific implementation mode is merely illustrative of the technical solution of the present invention and unrestricted,
Although being described the invention in detail with reference to example, it will be understood by those of ordinary skill in the art that, it can be to the present invention
Technical solution be modified or replaced equivalently, without departing from the spirit of the technical scheme of the invention and range, should all cover
In the scope of the claims of the present invention.
