Technical field
The invention belongs to technical field of electrical equipment, the stabilization knot of more particularly to a kind of low voltage isolation switch contact supporting
Structure.
Background technology
Need to cut off the electricity supply when electric equipment is repaired, maintenance part is isolated with live part, and keep effective isolation
Distance, is at this moment accomplished by using low voltage isolation switch.Conventional low voltage isolation switch mainly includes housing, switch contact machine at present
Structure, contacts cover, manually operated axle and handle；Wherein switch contact mechanism is located at the inside of housing；Contacts cover is arranged on switch
Switch contact actuator on the upper end of contact mechanism, and switch contact mechanism is in a movable manner through being arranged on contacts cover
On perforate in；The bottom of manually operated axle is connected with an action bars, the outer end of action bars and opening on the outside of contacts cover
Close contact actuator upper end side to be in contact, the upper end of manually operated axle extends to hull outside；Handle is then connected to behaviour manually
Make the outer end of axle.When staff move handle and low voltage isolation switch is carried out point, closing operation when, in the drive of handle
Under, manually operated axle will produce rotation, so as to drive action bars accordingly to rotate, then switch contact actuator touches driving switch
Head mechanism on contact and make its separate or close.But, this low voltage isolation switch can not be met when contact is being closed or divided
When opening, before mechanism's energy-stored spring releases energy, contact supporting can not have the requirement of any action, there is potential safety hazard.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of rock-steady structure of low voltage isolation switch contact supporting, its
Low voltage isolation switch be can guarantee that in the state for separating or closing, contact supporting all remains stationaries are motionless.
Therefore, technical program of the present invention lies in：
A kind of rock-steady structure of low voltage isolation switch contact supporting, including contact supporting, spring and cover plate；On the cover plate
It is provided with track；The contact supporting is arranged on the cover plate, can be slided along the track；
The cover plate is provided with groove, and the spring is transversely mounted in the groove, and the groove is protruded in its side
Upper edge；The contact supporting correspondence spring installation place is provided with arc groove, the shape of the arc groove and the bullet
The shape that spring protrudes the groove part matches；The arc groove has two, and both distances are equal to low voltage isolation switch
Switch stroke once.
Further, the spring is arranged on when in the groove, and it can occur elastically-deformable direction with the contact branch
Glide direction of the frame on the cover plate is vertical.
Further, the height at the position of the spring protrusion groove accounts for the 1/10~1/3 of the spring overall diameter.
Further, spring is torsion spring, and groove is a rectangular channel, is respectively provided on two sides with the installation site of torsion spring.
Further, the cover plate is provided with two multiple grooves, and spring, the side surface of each spring are respectively mounted in each groove
Protrusion installs the upper edge of groove；Described each spring installation place of contact supporting correspondence is equipped with a pair of arc grooves, institute
A pair of shapes of arc groove are stated to match with the shape of each spring protrusion groove part；A pair of distances of arc groove are equal to low
Pressure disconnecting switch switch stroke once.
The rock-steady structure of the low voltage isolation switch contact supporting that the present invention is provided is to utilize the spring disposed on cover plate and touch
The fluting that head bracket bottom is provided with is engaged, make contact supporting separate or close in the state of, the spring appliance for releasing single on cover plate
Rise into the fluting of contact supporting bottom, therefore contact supporting is not in the absence of external forces the feelings for moving left and right
Condition.In addition, the rock-steady structure of this contact supporting has reasonable in design, simple, low cost, and without isolating to former low pressure
The advantages of construction of switch is modified.
Brief description of the drawings
The part broken away view of the rock-steady structure of the low voltage isolation switch contact supporting that Fig. 1 is provided for the present invention；
Fig. 2 is that after contact supporting rotates, will be provided with the figure that arc groove face is set to sightingpiston；
Fig. 3 is the profile that contact supporting is in installment state；
The rock-steady structure of the low voltage isolation switch contact supporting that Fig. 4 is provided for the present invention is in gate-dividing state structure chart.
Specific embodiment
Technical scheme is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figures 1 to 3, a kind of rock-steady structure of low voltage isolation switch contact supporting, including contact supporting 1, the and of spring 2
Cover plate 3；Cover plate 3 is provided with track or draw-in groove；Contact supporting is installed on the cover board, can be slided along track or draw-in groove；
Cover plate 3 is provided with groove 301, and spring 2 is transversely mounted in groove 301, and the top of groove 301 is protruded in its side
Edge；The correspondence spring 2 of contact supporting 1 installation place is provided with arc groove 101, and shape and the spring 2 of arc groove 101 protrude groove
The shape of 301 parts matches；Arc groove 101 has two, and both distances are equal to low voltage isolation switch switch row once
Journey.
Spring 2 is arranged on when in groove 301, and it can occur elastically-deformable direction and cunning of the contact supporting 1 on cover plate 3
Dynamic direction is vertical.It is preferred that, the height at the position of the protrusion groove 301 of spring 2 accounts for the 1/10~1/3 of the overall diameter of spring 2.Spring 2 is
Torsion spring, groove 301 is a rectangular channel, is respectively provided on two sides with the installation site of torsion spring.
Used as one embodiment of the present of invention, cover plate 3 is provided with two or more grooves 301, each groove 301 pacifies respectively
