Detailed Description
The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, an electric leakage switch with protection casing, includes casing 1, the casing is equipped with the guard shield 2 that can dismantle the connection outward, the casing with the cooperation of guard shield joint, the casing lateral wall is equipped with guide way 11, be equipped with on the guard shield with guide way sliding fit's slide 21. During installation, the sliding plate and the guide groove which are in sliding fit are arranged, and the shell and the protective cover are connected together in a clamping mode, so that the installation is convenient.
In this embodiment, as shown in the figure, the slide both sides all are equipped with first arch 3, be equipped with on the guide way lateral wall with first protruding joint complex first draw-in groove 4. After the sliding in place, the first protrusion and the first clamping groove which are in clamping fit are used for connecting the protective cover and the shell.
In this embodiment, the cross-section of the first protrusion is a right triangle, as shown in the figure.
In this embodiment, as shown in the figure, the first protrusion includes a slope 31 in sliding fit with the inner wall of the guide groove and a blocking surface 32 in snap fit with the first slot. The slope can fall into first draw-in groove after sliding to the right place along the guide way inner wall to be equipped with and block the face and prevent deviating from.
In this embodiment, as shown in the figure, the outer wall of the housing is further provided with a second protrusion 12, and the shield is provided with a second clamping groove 22 in clamping fit with the second protrusion. The second protrusion may have a similar structure to the first protrusion, i.e., a right triangle.
In this embodiment, as shown in the figure, a baffle 5 which can be rotatably arranged is arranged on the shield, and a plug 51 which is used for being in clamping fit with the screw hole 91 on the circuit breaker is arranged on the baffle. The baffle can be hinged with the protective cover or directly made of changeable materials, such as plastics, and the plug extends into the screw hole after being rotated, so that the protective function is achieved.
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 casing 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 blocking plate includes a sheet body 141 and a connecting portion 142 connected to the housing, and the thickness of the connecting portion is smaller than that of the sheet body. Is convenient to be detached.
