Description
Technical field
The utility model is related to a kind of breaker, more particularly to a kind of contact of breaker component.
Background technology
Breaker is called air switch, has the function of overload, short circuit and low-voltage protection, the energy of energy protection circuit and power supply
Power.It can be used to distribute electric energy, infrequently start asynchronous motor, be protected to implementations such as power circuit and motor, when it
When occurring serious overload or short circuit and the failures such as under-voltage can automatic shutdown circuit, function is equivalent to Fuse switch
With the combination for crossing underheat relay etc..But existing breaker is susceptible to the accidents such as mistrip, gives after using one end time
People cause certain economic loss or personal safety.
Utility model content
The purpose of this utility model is that a kind of simple in structure, easy to operate, lower-cost contact of breaker of offer
Component.
To achieve the goals above, the technical solution adopted in the utility model is such：The breaker of the utility model
Contact assembly, including static contact and moving contact, static contact and moving contact are arranged in arc-chutes, and pull rod is provided on moving contact,
Further include bottom plate, pedestal, push plate, insulating bar, gag lever post and resetting spring, the pedestal be made of fixed plate and two support plates it is U-shaped,
Pedestal is arranged by fixed plate on bottom plate, is provided with corresponding mounting hole on two support plates, described push plate one end by axis pin with
Two support plates of pedestal are hinged, and the push plate other end and insulating bar and gag lever post one end are hinged, and the gag lever post other end is cut with scissors with bottom plate
It connects, described resetting spring one end is connect with insulating bar, and the other end is connect with bottom plate, and the pull rod in the middle part of connecting rod and push plate by cutting with scissors
It connects, connecting rod two end is hinged with pull rod and push plate respectively.
Preferably, the axis pin both ends are socketed with elastic ring, elastic ring is arranged in the mounting hole of support plate.
Preferably, the resetting spring is high-strength spring.
Compared with prior art, the utility model has the advantage of：The utility model is simple in structure, easy to operate, cost
It is relatively low, in use, controlling unlatching and the closure of movable contact and stationary contact by insulating bar, is limited, passed through by gag lever post
Resetting spring is resetted, the case where avoiding the occurrence of mistrip, safe to use.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Below in conjunction with attached drawing, the utility model is described in further detail.
Referring to Fig. 1, the contact of breaker component of the utility model, including static contact 1 and moving contact 2, static contact 1 are touched with dynamic
First 2 are arranged in arc-chutes, and pull rod 3 is provided on moving contact 2, further includes bottom plate 4, pedestal 5, push plate 8, insulating bar 6, gag lever post
9 and resetting spring 10, the pedestal 5 is made of U-shaped fixed plate and two support plates, and pedestal 5 is arranged by fixed plate on bottom plate 4,
Corresponding mounting hole is provided on two support plates, 8 one end of the push plate is hinged by two support plates of axis pin and pedestal 5, and push plate 8 is another
End and insulating bar 6 and 9 one end of gag lever post are hinged, and 9 other end of the gag lever post is hinged with bottom plate 4,10 one end of the resetting spring
It is connect with insulating bar 6, the other end is connect with bottom plate 4, and the pull rod 3 is hinged by connecting rod 7 and 8 middle part of push plate, 7 both ends of connecting rod point
Not hinged with pull rod 3 and push plate 8, the axis pin both ends are socketed with elastic ring, and elastic ring is arranged in the mounting hole of support plate, described
Resetting spring 10 is high-strength spring.
In use, controlling unlatching and the closure of movable contact and stationary contact by insulating bar 6, limited by gag lever post 9,
Gag lever post 9 is 45 degree hinged with bottom plate 4, the case where resetted by resetting spring 10, avoid the occurrence of mistrip, uses peace
Entirely.The utility model is simple in structure, easy to operate, and cost is relatively low, and axis pin both ends are socketed the mounting hole of elastic ring and 5 support plate of pedestal
Connection has certain elastic space, extends the service life of breaker.
