Detailed Description

The utility model is further described with reference to the accompanying drawings, wherein the isolating structure of the switching device comprises a shell 1, a wiring groove 2 and a mounting hole 3 are arranged on the shell, a partition board 4 is arranged between at least one group of adjacent wiring grooves, and a shielding part 41 is arranged on the partition board and is used for at least partially covering the mounting hole. Install the screw in the mounting hole, after the casing is installed to the baffle, can separate the wiring groove, increase creepage distance, preferably, all set up a baffle between every two wiring grooves to the bottom of baffle covers the mounting hole, has further strengthened the effect of keeping apart, and this shielding part can be a part of baffle, is the structure of a apron of analogy.

In this embodiment, as shown in the figure, the housing is provided with a mounting seat 11, and the mounting hole is disposed in the mounting seat. The mounting seat can also play a role in isolation, and a relatively closed cavity can be formed by matching the shielding part.

In this embodiment, as shown in the drawing, the housing is provided with a first slot 12, and the partition board includes a main board 411, and one side edge of the main board is in plug-in fit with the first slot. The first slot can be an arc slot, and can rotate after the partition board is inserted, so that the device is flexible.

In this embodiment, as shown in the drawing, the outer wall of the mounting seat is provided with a second slot 121, and the partition board includes an auxiliary board 412, and one side edge of the auxiliary board is in plug-in fit with the second slot. The second slot is a rectangular slot used for positioning after complete insertion, and is stable to install.

In this embodiment, as shown in the figure, the shielding portion is a baffle plate disposed at the bottom of the main board, and the baffle plate is disposed in the mounting hole. The outer wall of baffle can also clearance fit with the inner wall contact of mounting hole, realizes the effect of sheltering from.

In this embodiment, as shown in the figure, the device further comprises a base 5, and the base is detachably connected with the housing. The base is added, and the isolation effect is further improved.
