Abstract
This utility model provides a kind of strength extrusion stability type knife-like switch, it includes housing, cutter holder base is designed with the housing, plug-in strip is hinged with the front end shell of cutter holder base, the electric continued piece both sides for using in pairs are designed with catch, the electric continued piece bottom of the cutter holder base is designed with hydraulic cavities, the hydraulic pressure intracavity is designed with vertically to being deep into the sliding bar between the electric continued piece that uses, go deep into the hydraulic pressure intracavity in the sliding bar bottom, the sliding bar is slidingly sealed assembling with hydraulic cavities, flexible capsule is clamped between the electric continued piece and catch, the elastomeric bladder is accessed in the hydraulic cavities by VERTICAL TUBE, liquid of the hydraulic cavities built with insulation.When the knife-like switch is used in closure, electric continued piece connects electrical property more preferably to middle clamping, while the use time better and bigger clamping force of longer even electrical property causes plug-in strip not touched out easily, using safer.
Description
Technical field
This utility model belongs to low voltage electrical apparatus technology field, more particularly, to a kind of strength extrusion stability type knife-like switch.
Background technology
Switch typically refers to be made open circuit, make current interruptions or be made which flow the electronics unit to other circuits with a kind of
Part.Switch is divided into different rationality according to the difference of structure and power supply service condition, wherein knife-like switch also known as knife switch or
Disconnecting switch, it are most simply to use a kind of wide low-voltage electrical apparatus in manual electrical equipment.Knife-like switch is typically by lock
Cutter holder base phase wedging on knife and base（Or separate）, to connect（Or disjunction）Circuit.Traditional knife-like switch long-time uses it
Afterwards, its cutter holder base can become to loosen so that plug-in strip is connected defective tightness with cutter holder base, easily produce virtual connection so that circuit output
It is not sufficiently stable.And traditional cutter holder base clamps defective tightness to plug-in strip, easily touched out in touching.
Content of the invention
For above-mentioned problem, the purpose of this utility model is to provide one kind when plug-in strip closes dead, and cutter holder base is to plug-in strip
Clamping force increase arrive, be difficult during use disengage strength extrusion stability type knife-like switch.
This utility model solves the technical scheme adopted by its technical problem：The strength extrusion stability type knife-like switch includes
Housing, is hinged with plug-in strip in the front end shell for being designed with cutter holder base, cutter holder base in the housing, and the plug-in strip is by more than two panels
Blade and housing hinge, be designed with the sliding groove of corresponding plug-in strip top cutter on the housing, corresponding plug-in strip in the cutter holder base
Blade close dead position be designed with the electric continued piece for using in pairs；The electric continued piece both sides for using in pairs are designed with catch, the cutter holder
The electric continued piece bottom of seat is designed with hydraulic cavities, and the hydraulic pressure intracavity is designed with vertically to being deep between the electric continued piece to using
Sliding bar, the sliding bar bottom go deep into the hydraulic pressure intracavity, and the sliding bar is slidingly sealed assembling, the even electricity with hydraulic cavities
Flexible capsule is clamped between piece and catch, and the elastomeric bladder is accessed in the hydraulic cavities by VERTICAL TUBE, and the hydraulic cavities are built-in
There is the liquid of insulation.
Preferably, the partial cross section of hydraulic pressure intracavity is goed deep in the sliding bar bottom accumulates big sectional area to its upper.
Preferably, being pasted with gum elastic on the inside of the sliding groove.
The beneficial effects of the utility model are：When the strength extrusion stability type knife-like switch is used, when plug-in strip conjunction is dead, lock
The blade pressing of knife is deep in the hydraulic cavities in the upper end of the sliding bar, the bottom of the sliding bar, so as to by hydraulic pressure
The liquid of intracavity is expressed in elastomeric bladder, and the elastomeric bladder extrudes electric continued piece so that electric continued piece is produced to the middle deformation for clamping,
So paired electric continued piece can by plug-in strip blade parcel even closer, this knife-like switch closure when, electric continued piece to
Middle clamping, even electrical property is more preferable, while the use time better and bigger clamping force of longer even electrical property causes plug-in strip not
Can be touched easily and be held, using safer.
Description of the drawings
Fig. 1 is the structural representation of strength extrusion stability type knife-like switch frontal；
Fig. 2 is the structural representation in the section of strength extrusion stability type knife-like switch.
Specific embodiment
With reference to the accompanying drawings and examples this utility model is further illustrated：
As shown in embodiment in Fig. 1 and 2, this strength extrusion stability type knife-like switch includes housing 1, design in the housing 1
Have in cutter holder base 2, the front end shell of cutter holder base 2 and be hinged with plug-in strip 3, in this embodiment, the plug-in strip 3 by two panels blade with
Housing 1 is hinged, and is designed with the sliding groove 11 of 3 top cutter of corresponding plug-in strip on the housing 1, corresponding plug-in strip 3 in the cutter holder base 2
Blade closes dead position and is designed with the electric continued piece 21 for using in pairs；21 both sides of electric continued piece for using in pairs are designed with catch 22, described
21 bottom of electric continued piece of cutter holder base 2 is designed with hydraulic cavities 4, is designed with vertically to the company being deep into using in the hydraulic cavities 4
Sliding bar 5 between electric piece 21,5 bottom of the sliding bar go deep in the hydraulic cavities 4, and the sliding bar 5 is slided with hydraulic cavities 4
Sealing assembling, clamps flexible capsule 6 between the electric continued piece 21 and catch 22, the elastomeric bladder 6 is accessed described by VERTICAL TUBE
In hydraulic cavities 4, the hydraulic cavities 4 can not burning liquid built with insulation.So company is not resulted in when elastomeric bladder 6 ruptures leakage
Electricity, so when electric continued piece be not easy to when temperature is higher on fire.
As shown in Fig. 2 the partial cross section that 5 bottom of the sliding bar is goed deep in hydraulic cavities 4 accumulates big sectional area to its upper.
More liquid so can be squeezed out when the sliding bar 5 is pushed allows elastomeric bladder to produce larger pressure.Specifically setting
Timing, the inner side of the sliding groove 11 are pasted with gum elastic.So easily the blade of plug-in strip 3 can be clamped so that knife
Piece is difficult to loosen during slippaging.
Preferred embodiment of the present utility model is the foregoing is only, not in order to limit this utility model, all in this practicality
Within new spirit and principle, any modification, equivalent substitution and improvements that is made etc. should be included in guarantor of the present utility model
Within the scope of shield.
