SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough of background art, the utility model provides a switching device's insulating limit structure, the N utmost point wire of mainly solving present switch adopts the sleeve pipe to carry out the problem of insulating the high and easy short circuit of cost of labor.
The utility model adopts the technical proposal that:
the utility model provides a switching device's insulating limit structure, includes the casing, one side is equipped with the first chamber of main line unit installation in the casing, and the opposite side is equipped with the second chamber that is used for the installation of N utmost point wire, be equipped with the circuit board in the second chamber and be used for separating the circuit board with the limit structure that just right the N utmost point wire circumference is carried on spacingly.
The limiting structure is a limiting plate arranged in the second cavity, a limiting groove used for limiting the circumferential direction of the N-pole lead is formed in the inner wall of the limiting plate, and the limiting plate is partially arranged between the N-pole lead and the circuit board.
The limiting plate comprises a supporting plate, a first limiting plate and a second limiting plate, wherein the first limiting plate and the second limiting plate are perpendicular to each other, the supporting plate is connected with the inner wall of the bottom of the shell, the supporting plate is connected with the first limiting plate, and a gap is formed between the second limiting plate and the inner wall of the bottom of the shell.
The support plate, the first limiting plate and the second limiting plate are integrally manufactured.
The limiting plates are provided with at least two limiting plates along the length direction of the N-pole lead.
The support plate is arranged between the circuit board and the N-pole lead.
The second limiting plate is arranged between the circuit board and the N-pole lead.
The utility model has the advantages that: the utility model provides a switching device's insulating limit structure increases spacing and insulating effect to the N utmost point wire, reduces the condition and the reduce cost of short circuit.

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.
