Detailed Description
The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
Example one
As shown in fig. 1 and 2, an insulating screw cover comprises a panel body 1, an embedding body 2 and at least one buckling strip 3; the embedding body 2 is fixedly arranged on one side of the panel body 1, and the fastening strips 3 are fixedly arranged on the embedding body 2 respectively.
Specifically, in the present embodiment, the panel body 1 is a rectangular plate body.
Specifically, in the present embodiment, the insert 2 has a rectangular ring structure.
Specifically, in this embodiment, the number of the fastening strips 3 is two; two fastening strips 3 are respectively fixed on two sides of the embedding body 2. The front end of the fastening strip 3 forms a fastening hook which is used for fastening with the side plate 4.
Specifically, in this embodiment, the panel body 1, the embedded body 2 and the fastening strip 3 are an integral structure and made of PC material.
The insulating screw cover of this embodiment adopts PC an organic whole to make for shelter from the connecting screw 5 that is used for connecting the vacuum bubble support on the baffle, prevent that the screw from discharging, this insulating screw cover can be stable and curb plate 4 between the erection joint, rely on insulating screw cover rectangle annular embedding body 2, make shape labyrinth between insulating screw cover and the curb plate 4, increase the creepage distance that insulating screw covered, play good insulating effect to connecting screw 5 on the curb plate 4.
Example two
As shown in fig. 3 to 5, a circuit breaker switch includes two side plates 4, a vacuum bulb holder, and an insulating screw cover in the first embodiment. The two side plates 4 are respectively provided with a bolt through hole 41, and the vacuum bubble support is screwed through a connecting bolt 5 passing through the bolt through hole 41 so as to be fixed between the two side plates 4.
