Abstract
The utility model discloses an earthing switch insulation cover. The earthing switch insulation cover comprises an insulation cover which is a semi-open cuboid structure, wherein the insulation cover has an open upper flat surface and an open front surface; an earthing switch edge slot is formed on the upper end of the rear surface of the insulation cover; an annular dowel hole is formed below the earthing switch edge slot; two insulation cover fixing holes are arranged on the insulation cover; and a square hole is arranged on the bottom surface of the insulation cover. According to the utility model, the insulation cover is arranged between a static contact and an insulator so as to be insulated from the outside. Therefore, the insulation cover has the advantages of being excellent in safety, being favorable for reducing the size of a switch cabinet and lowering the cost. The earthing switch insulation cover can be widely used in various switch cabinets.
Description
Technical field
The utility model relates to a kind of insulating cover, particularly a kind of insulating cover of earthed switch.
Background technology
Earthed switch be in the electric wiring in order to the device of ground connection, be installed in the switch cubicle as the one of which.The structure of typical case's earthed switch is as shown in Figure 3, and the diagram earthed switch comprises earthed switch 1, and earthed switch 1 comprises insulator 1A, fixed contact 1B, fixed contact holder 1C and dynamic cutter head 1D.Fixed contact 1B is fixed on the fixed contact holder 1C, and fixed contact holder 1C is connected in electric main circuit and is fixed on the insulator upper surface, thereby with the electric loop insulation against ground.
When electric main circuit need join with ground, when for example needing repairing, operating personnel can engage the dynamic cutter head 1D of earthed switch and fixed contact 1B through operation sequence.The structure of existing earthed switch Fig. 3 is generally open type; Charged fixed contact is exposing all the time; This has not only greatly reduced the fail safe of earthed switch operation; And in order to guarantee necessary insulation property, in switch cubicle, just have to strengthen and other electric elements between mounting distance, thereby also just increased switch cubicle volume, improved the material cost of switch cubicle product.
The utility model content
The insulating cover that the technical problem that the utility model will solve provides a kind of earthed switch solves the existing low problem of earthed switch fail safe.
For achieving the above object, the technical scheme of the utility model is following:
A kind of insulating cover of earthed switch comprises insulating cover, and said insulating cover is the rectangular structure of semi-open-type; The last plane of said insulating cover is an open state; The front of said insulating cover is an open state, and the upper end, back of said insulating cover is provided with the quiet edge of a knife groove of earthed switch, and the below of the quiet edge of a knife groove of said earthed switch is provided with annular cover hand-hole; Said insulating cover is provided with two insulating cover fixing holes, and the bottom surface of said insulating cover is provided with square hole.
Preferably, the quiet edge of a knife groove of said earthed switch is a rectangle.
Through technique scheme, the beneficial effect of the utility model is:
The said earthed switch insulating cover of the utility model is arranged at fixed contact in the insulating cover; Thereby charged fixed contact and periphery are formed insulation, and this has not only improved the fail safe of device operation greatly, and has brought great benefit for the design and the manufacturing of switch cubicle; Can be under the prerequisite that guarantees insulation property; Reduce the mounting distance between earthed switch and other electric elements, thereby dwindle the volume of switch cubicle, also reduced the material and the manufacturing cost of switch cubicle simultaneously.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Extremely shown in Figure 3 referring to Fig. 1; The insulating cover of a kind of earthed switch of the utility model comprises insulating cover 2, and said insulating cover 2 is the rectangular structure of semi-open-type, and the last plane of said insulating cover 2 is an open state; The front of said insulating cover 2 is an open state; The upper end, back of said insulating cover 2 is provided with the quiet edge of a knife groove of earthed switch 2A, and the quiet edge of a knife groove of earthed switch 2A is a rectangle, and the below of the quiet edge of a knife groove of said earthed switch 2A is provided with annular cover hand-hole 2C; Said insulating cover 1 is provided with two insulating cover fixing hole 2B, and the bottom surface of said insulating cover 1 is provided with square hole 2D.
During the utility model assembling, earlier earthed switch 1 upper static contact 1B is unloaded, be loaded on earthed switch 1 insulator 1A to insulating cover 2 respectively and go up on the plane; The cover hand-hole 2C of insulating cover 2 is inserted in earthed switch insulator 1A and goes up on the plane; The corresponding earthed switch insulator of the fixing hole 2B of insulating cover 2 1A goes up the screwed hole (not marking among the figure) on the plane; Insulating cover 2 is fixed on the insulator 1A of earthed switch 1 with bolt (not marking among the figure), the fixed contact 1B that unloads is before retightened on the insulator 1A of earthed switch 1.
The utility model is simple in structure, and insulation property are strong, can be widely used in all kinds of switch cubicles.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
