Description
Technical field
The present invention relates to low voltage component field, and in particular to a kind of knife-like switch.
Background technology
Knife-like switch is also known as knife switch or disconnecting switch, and it is most simply to use wide one kind in manual electrical equipment
Low-voltage electrical apparatus, as infrequently manual ON and disjunction AC and DC circuit or it is used as disconnecting switch.Its energy insulating power supply, with
Ensure the safety of circuit and maintenance of equipment；Or used as infrequently connecting with the load below disjunction rated current；Disjunction is born
Carry, such as infrequently connect and the little low-voltage circuit of breaking capacity or directly initiate small-capacity motor；Knife-like switch, which is in, to be disconnected
During position, it can substantially observe, can ensure that the safety of circuit maintainer.
The plug-in strip of knife-like switch is typically straight plug-in strip, and intermediate plate is process using flexure strip, utilizes the resilient clips of intermediate plate
Tight plug-in strip, as the increase of on-off times, intermediate plate easily lose elasticity during use, cause the loose contact between intermediate plate and plug-in strip,
Electric arc is produced, burns intermediate plate and plug-in strip, service life is short；Simultaneously as producing electric arc between intermediate plate and plug-in strip, operator pulls
When handle is cut off the electricity supply, burn easily occurs or electricity hinders accident, poor safety performance, potential safety hazard be present.
The content of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide one kind is simple in construction, reasonable in design, makes
With convenient knife-like switch.
To achieve the above object, the technical solution adopted by the present invention is：A kind of knife-like switch, including base, knife-edge moving contact,
Insulation board, static contact, column, spring；Static contact is fixed with described base；The outside of static contact is provided with U-shaped groove two；It is quiet
The both sides of contact are provided with column；Column is fixed on base；Column is provided with spring；One end of spring is fixed on column, separately
One end is in the U-shaped groove two of static contact；Base is additionally provided with knife-edge moving contact；The outside of knife-edge moving contact is provided with insulation board；Knife
The top of shape moving contact is provided with projection；
Preferably, described base is provided with U-shaped groove one；
Preferably, described static contact is fixed in the U-shaped groove one of base；
After said structure, the present invention has the beneficial effect that：A kind of knife-like switch of the present invention, its dynamic/static contact can be close
Contact, avoids producing electric arc because of loose contact, safe and reliable, service life length, and with it is simple in construction, set rationally, system
Make low cost and other advantages.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, without having to pay creative labor, may be used also
To obtain other accompanying drawings according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of static contact and column.
Description of reference numerals：
1st, knife-edge moving contact；2nd, base；3rd, insulation board；4th, column；5th, static contact；6th, spring；1-1, projection；2-1, U-shaped groove
One；5-1, U-shaped groove two.
Embodiment
Below in conjunction with the accompanying drawings, the present invention is further illustrated.
Referring to shown in Fig. 1-2, the technical scheme that present embodiment uses is：A kind of knife-like switch, including base 2, knife
Shape moving contact 1, insulation board 3, static contact 5, column 4, spring 6；Static contact 5 is fixed with described base 2；Outside static contact 5
Side is provided with the 5-1 of U-shaped groove two；The both sides of static contact 5 are provided with column 4；Column 4 is fixed on base 2；Column 4 is provided with spring
6；One end of spring 6 is fixed on column 4, and the other end is in the 5-1 of U-shaped groove two of static contact 5；Base 2 is additionally provided with knife-edge and moved
Contact 1；The outside of knife-edge moving contact 1 is provided with insulation board 3；The top of knife-edge moving contact 1 is provided with raised 1-1；
Preferably, described base 2 is provided with the 2-1 of U-shaped groove one；
Preferably, described static contact 5 is fixed in the 2-1 of U-shaped groove one of base 2；
The static contact 5 of present embodiment is fixed in the 2-1 of U-shaped groove one of base 2, because static contact 5 is U-shaped structure, bottom
The 2-1 of U-shaped groove one of seat 2 is unlikely to deform the U-shaped bending part of static contact 5；Spring 6 on column 4 is in impaction state all the time,
Spring force acts on static contact 5 always, clamps static contact 5, is unlikely to deform, and is in close contact with knife-edge moving contact 1；Knife-edge
The raised 1-1 on the top of moving contact 1 can be when there is micro-deformation in static contact 5, moreover it is possible to be in close contact, avoid because of loose contact and
Produce electric arc.
It is described above, it is merely illustrative of the technical solution of the present invention and unrestricted, those of ordinary skill in the art are to this hair
The other modifications or equivalent substitution that bright technical scheme is made, without departing from the spirit and scope of technical solution of the present invention,
It all should cover among scope of the presently claimed invention.
