Detailed Description
The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, the electric shock preventing structure of the low-voltage switch comprises a shell 1, wherein a mounting hole 2 is formed in the shell, a wiring screw 3 is arranged in the mounting hole, a reinforcing ring 4 is arranged in the mounting hole, and the reinforcing ring is arranged above the wiring screw. When the finger stretched into, at first can blockked by the beaded finish, even if the minority part stretched into the beaded finish, owing to prop at the inner wall of beaded finish, also reduced shells inner wall moreover and propped the degree, in addition, the axial of beaded finish was equipped with the through-hole that is used for binding screw to pass through, and the diameter of this through-hole is less than the diameter of mounting hole.
In the present embodiment, as shown in the figure, the housing includes a first housing 10 and a second housing 11 which are detachably connected, and the mounting hole is partially provided on the first housing and partially provided on the second housing. On the switch is pressed in the support of split type concatenation, the casing is propped open more easily, and the inner wall at the beaded finish can be applyed to the existence power of beaded finish, reduces shells inner wall atress to reduce the degree that the casing was propped open.
In this embodiment, as shown, the reinforcement ring is disposed on the first housing.
In this embodiment, as shown in the figure, the first housing includes a connecting portion 101 connected to the second housing, and the reinforcing ring is disposed opposite to the connecting portion. The first shell and the second shell can be connected through screws, the connecting portion plays a role in auxiliary fixing, and the reinforcing ring is arranged nearby to play a better role.
In this embodiment, as shown in the figure, the connecting portion is a plug, and the second housing is provided with a jack matched with the plug.
In this embodiment, as shown in the figure, an accommodating groove 13 is formed in the housing, a blocking piece 14 is formed on the housing, and the blocking piece is opposite to the accommodating groove, and when the blocking piece is broken, the accommodating groove is exposed and used for placing the busbar. The holding tank in the casing is used for the busbar to connect, but not every low-voltage switch all uses, need use the time-out with the separation blade rupture pull down can.
In this embodiment, as shown in the figure, one end of the blocking piece is connected with the casing, and a through groove 15 is arranged between the circumferential direction and the outer wall of the casing. Is convenient to be detached.
In this embodiment, as shown in the figure, the baffle includes a sheet body 141 and a connecting sheet 142 connected to the housing, and the thickness of the connecting sheet is smaller than that of the sheet body. Is convenient to be detached.
In the description of the present invention, it is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
