Detailed Description
The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, the insulation limiting structure of the switch electric appliance comprises a shell 1, a first cavity 11 for installing a main circuit unit is formed in one side in the shell, a second cavity 12 for installing an N-pole lead 4 is formed in the other side in the shell, a circuit board 40 and a limiting structure used for separating the circuit board from the N-pole lead and limiting the N-pole lead in the circumferential direction. The main line unit can be for the part of little disconnected switch, for prior art, no longer gives unnecessary details, and conventional N utmost point wire adopts sheathed tube mode, because service life or sharp thing puncture probably appear naked circumstances, if the structure that does not keep apart under this circumstances can appear the condition such as short circuit with the circuit board contact, this problem of solution that the limit structure of this application can be fine, and it specifically can adopt structures such as limiting plate and spacing cover.
In this embodiment, as shown in the figure, the limiting structure is a limiting plate 5 arranged in the second cavity, a limiting groove 51 used for limiting the circumferential direction of the N-pole lead is formed in the inner wall of the limiting plate, and part of the limiting plate is arranged between the N-pole lead and the circuit board. The limiting plate can be in an L-shaped or U-shaped or C-shaped structure to limit the radial direction of the N-pole lead, and the limiting plate can be close to or have a certain allowable space, such as a space of 10mm-20mm.
In the present embodiment, as shown in the figure, the limiting plates include a supporting plate 50, and a first limiting plate 52 and a second limiting plate 53 perpendicular to each other, the supporting plate is connected to the inner wall of the bottom of the casing, the supporting plate is connected to the first limiting plate, and a gap 54 is provided between the second limiting plate and the inner wall of the bottom of the casing. The gap is used for enabling the N pole to be manually pushed to pass through, and the N pole can enter and exit only with certain force, so that the limiting effect is achieved, and meanwhile, the assembling is convenient.
In this embodiment, as shown in the figure, the support plate, the first limit plate and the second limit plate are integrally made. Preventing manufacturing.
In this embodiment, as shown in the figure, at least two limiting plates are arranged along the length direction of the N-pole lead. Can better play spacing and insulating effect.
In this embodiment, as shown in the figure, the support plate is disposed between the circuit board and the N-pole lead. The supporting plate can better isolate the N pole lead and the circuit board.
In this embodiment, as shown in the figure, the second limiting plate is disposed between the circuit board and the N-pole lead. The opposite orientation of two limiting plates can be better play spacing effect, prevent to rock and skew.
The embodiments described with reference to the figures are exemplary intended for the purpose of illustrating the invention and are not to be construed as limiting the invention. The examples should not be construed as limiting the present invention, but any modifications made based on the spirit of the present invention should be within the scope of the present invention.
