Brief description of the drawings
Fig. 1 is the sectional view of the utility model embodiment；
Fig. 2 is the cutaway view Amplified image of the utility model grounding contact；
Fig. 3 is the cutaway view Amplified image of existing grounding contact.
Embodiment
To further illustrate each embodiment, the utility model is provided with accompanying drawing.These accompanying drawings are in the utility model discloses
A part for appearance, it can coordinate the associated description of specification to explain the running of embodiment original mainly to illustrate embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new
The advantages of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
It is shown in Figure 3, existing Shells of High Voltage Switches, the groove of the annular groove 41 in square fillet face in its grounding contact 4
Depth relatively depth is 3mm, and being shaped as groove is square, and the annular groove 41 in square fillet face is located at the long-armed installation of grounding contact 4
The top in hole 42, furthermore the long-armed external diameter of grounding contact 4 is larger, easily blocked when being shunk so as to the epoxy resin in body by groove
And cause to ftracture, the service life of high-voltage switch gear is influenceed, and potential safety hazard be present.
Referring to shown in Fig. 1 and Fig. 2, the present embodiment discloses a Shells of High Voltage Switches, including body 1, lower contact 2, L-shaped
Grounding contact 3, lower contact 2 is fixedly installed on the top of body 1 and (fixed using screw lock or other mechanical means, herein
Repeat no more), grounding contact 3 be fixedly installed on the side lower part of body 1 one (fixed using screw lock or other mechanical means,
Will not be repeated here), wherein, body 1 is made up of the epoxy resin of good insulation preformance.The end of the long-armed and galianconism of grounding contact 3
Side is respectively provided with mounting hole (mounting hole is screw or other mechanical mounting holes, be will not be repeated here), in grounding contact 3
Long-armed outer surface be equipped with multiple annular grooves 31, the groove face of the annular groove 31 is arc surface, the circular arc half of the arc surface
