Description
Technical field
It the utility model is related to a kind of breaker, more particularly to a kind of drawer type frame breaker.
Background technology
With the development of science and technology breaker is widely used, frame-type circuit breaker is one in breaker application
Kind more typical breaker structure, also known as omnipotent breaker, it is that one kind can be connected, carried and disjunction normal circuit bar
Electric current under part, one kind machinery of certain time and breaking current can be also connected, carried under defined improper circuit condition
Device for switching；Wherein frame-type circuit breaker can be divided into drawer type and fixed two parts, due to portion in drawer type frame breaker
After separation structure improves, its intraware is installed in procapsid, intraware and the unmatched situation of housing occurs.
The content of the invention
The utility model is solution the deficiencies in the prior art, there is provided a kind of more optimized structure, and can be with inside
The drawer type frame breaker of component matching.
To achieve the above object, the utility model employs a kind of drawer type frame breaker, including drawer chassis, conductive system
System, contact system and operating mechanism, conducting system include wiring bus-row and bridge-type contact, and drawer chassis includes drawer chassis bottom plate, taken out
Bridge-type contact is provided with drawer bottom plate, and the bridge-type contact is formed with wiring bus-row and connected, and 6 knots are provided with drawer chassis bottom plate
Structure identical cavity, its 6 cavitys can be divided into two parts, and the two parts are used at horizontal axis and are symmetrical arranged, drawer chassis
For base plate interior at horizontal axis, it is provided with wiring bus-row contact groove, and the wiring bus-row close to upper and lower both sides opening position
Contact groove is at 6 cavity its same positions using being uniformly arranged；The wiring bus-row contact groove and both sides in its residing cavity
An isosceles dovetail groove is formed at vertical plane, its groove top of the isosceles dovetail groove is more than bottom land.
Above-mentioned drawer type frame breaker, two parts can be divided into by being provided with 6 cavitys in the drawer chassis bottom plate, this two
Divide using being symmetrical arranged at horizontal axis, drawer chassis base plate interior is at horizontal axis, and it is close to upper and lower two side position
Place is provided with wiring bus-row contact groove, and in 6 cavitys, its use that mutually exists together is uniformly arranged the wiring bus-row contact groove；Due to taking out
After the assembling of drawer formula frame circuit breaker, because the wiring bus-row external part in conducting system is long, due to its fixation side of wiring bus-row
Formula reaches required fixation simply to coordinate with its lower end assemblies merely, but during carrying or use, drawer type framework
Breaker can be influenceed situation about rocking occur by external force；It is in carrying for simply single shake, is used if it is in
In its influence but less it is identical, because bus in wiring bus-row by drawing, if its rock occurring interference, interfering other assemblies just
Often use, potential safety hazard notably be present.
The utility model is further arranged to, and drawer chassis bottom plate is engaged with its internal structure, the wiring in conducting system
Its top of busbar is placed in wiring bus-row contact groove, and the wiring bus-row forms spacing cooperation with wiring bus-row contact groove.
Above-mentioned drawer type frame breaker, wiring bus-row contact groove is not provided with the procapsid, in the effect above
In mentioned situation, after wiring bus-row installation at procapsid, at location, to set a stopping means,
Procapsid need to be redesigned, members be elapsed into one wiring bus-row contact groove of middle insertion at intermediate position, by this
Wiring bus-row contact groove and the spacing cooperation of wiring bus-row, by it is spacing can by during wiring bus-row use by external force rock can
Energy property minimizes,；This newly-increased component and remaining component be not because the displacement of component any original occurs not at drawer chassis bottom plate
Due influence, the connection reached on the contrary between each parts is more compact, and structure is more reliable, more rationally.
Brief description of the drawings
Fig. 1 is the drawer chassis baseplate internal structure schematic perspective view in the utility model drawer type frame breaker；
Fig. 2 is the drawer chassis baseplate internal structure floor map in the utility model drawer type frame breaker；
Fig. 3 is the partial enlarged drawing at A in Fig. 1；
Embodiment
Such as Fig. 1-3, the utility model specific embodiment uses a kind of drawer type frame breaker, including drawer chassis, conduction
System, contact system and operating mechanism, conducting system include wiring bus-row and bridge-type contact, and drawer chassis includes drawer chassis bottom plate 1,
Bridge-type contact is provided with drawer-bottom board, and the bridge-type contact is formed with wiring bus-row and connected, and 6 are provided with drawer chassis bottom plate 1
Individual structure identical cavity 11, its 6 cavitys 11 can be divided into two parts, and the two parts are used at horizontal axis 12 and symmetrically set
Put, inside drawer chassis bottom plate 1 at horizontal axis 12, it is provided with wiring bus-row contact groove close to upper and lower both sides opening position
13, and the wiring bus-row contact groove 13 at 6 cavity 11 its same positions using being uniformly arranged；Wiring bus-row contact groove 13 with
An isosceles dovetail groove is formed in its residing cavity 11 at the vertical plane of both sides, its groove top 132 of the isosceles dovetail groove is more than bottom land 131.
According to above-described embodiment, the utility model drawer chassis bottom plate 1 is engaged with its internal structure, connecing in conducting system
Its top of line busbar is placed in wiring bus-row contact groove 13, and the wiring bus-row forms spacing match somebody with somebody with wiring bus-row contact groove 13
Close.
