Description

Overvoltage inhibiting apparatus

Technical field

This utility model is related to overvoltage equipment technical field, more particularly to overvoltage inhibiting apparatus.

Background technology

In prior art, overvoltage suppression cabinet is connected with high pressure equipment, when external voltage is excessive, by Overvoltage suppressing The electric current of cabinet will be bigger, and when current is excessive, the electronic devices and components on circuit board on overvoltage suppression cabinet are possible to out The phenomenon of existing electric arc occurs, particularly in thunderstorm weather, it is easy to cause the electronics unit device on the circuit board of overvoltage suppression cabinet Part causes the phenomenon burnt to occur because of electric arc, so as to waste ample resources and cost.

Utility model content

In view of this, it is necessary to one kind is provided and avoids electric arc from burning electronic devices and components, and it is excessively electric with cost to economize on resources Pressure restraining device.

This utility model is achieved in that overvoltage inhibiting apparatus, including body, circuit board, shell, plank layer, gold Category inner wall layer and arc extinguishing pin, the body and circuit board are separate, and the circuit board electrically connects described by winding displacement , in the inner chamber of the shell, the inwall of the shell is provided with one layer of plank layer for body, the body and circuit board, The inwall of the plank layer is provided with layer of metal inner wall layer, one of metal inner surface of the circuit board and described body side surface Layer is parallel, and circuit board and the spacing distance of the metal inner surface layer are 10～100mm, and the arc extinguishing pin is located at the circuit board And the interval of the metal inner surface layer between, and arc extinguishing pin is vertically fixed on metal inner surface layer, on the metal inner surface layer It is provided with multiple equally distributed arc extinguishing pins, the metal inner surface layer ground connection.

Further, the material of the arc extinguishing pin is conducting metal material.

The advantage of overvoltage inhibiting apparatus that this utility model is provided is：This utility model is simple and reasonable, passes through The combining form of body, circuit board, shell, plank layer, metal inner surface layer and arc extinguishing pin is set, and body and circuit board are mutually solely Vertical, be prevented effectively from and other parts on body burnt because of the electric arc that circuit board is produced, and by arranging arc extinguishing pin, see arc extinguishing Pin is located between the circuit board and the interval of the metal inner surface layer, and arc extinguishing pin is vertically fixed on metal inner surface layer, The metal inner surface layer is provided with multiple equally distributed arc extinguishing pins, the metal inner surface layer ground connection, when the electronics on circuit board When components and parts produce electric arc, directly absorbed by arc extinguishing pin, and be grounded to carry out extinguishing arc by the metal inner surface layer, be prevented effectively from Electric arc burns the electronic devices and components on circuit board, so as to save ample resources and cost.

Description of the drawings

Structural representations of the Fig. 1 for this utility model overvoltage inhibiting apparatus.

Specific embodiment

In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only to explain This utility model, is not used to limit this utility model.

Refer to Fig. 1, structural representations of the Fig. 1 for this utility model overvoltage inhibiting apparatus.

The overvoltage inhibiting apparatus, including body 10, circuit board 20, shell 30, plank layer 40,50 and of metal inner surface layer Arc extinguishing pin 60, the body 10 and circuit board 20 are separate, and the circuit board 20 electrically connects the body by winding displacement 10, in the inner chamber of the shell 30, the inwall of the shell 30 is provided with one layer of institute for the body 10 and circuit board 20 Plank layer 40 is stated, the inwall of the plank layer 40 is provided with layer of metal inner wall layer 50, the circuit board 20 and 10 side of the body One of metal inner surface layer 50 in face is parallel, and the spacing distance of circuit board 20 and the metal inner surface layer 50 be 10～ 100mm, the arc extinguishing pin 60 are located between the circuit board 20 and the interval of the metal inner surface layer 50, and arc extinguishing pin 60 hangs down Directly it is fixed on metal inner surface layer 50, the metal inner surface layer 50 is provided with multiple equally distributed arc extinguishing pins 60, the metal Inner wall layer 50 is grounded.

The material of the arc extinguishing pin 60 is conducting metal material, is easy to what the electronic devices and components on absorbing circuit plate 20 were produced Electric arc.

This utility model is simple and reasonable, by arranging body, circuit board, shell, plank layer, metal inner surface layer and going out The combining form of arc pin, body and circuit board are separate, are prevented effectively from because the electric arc that circuit board is produced is burnt on body Other parts, and by arranging arc extinguishing pin, see arc extinguishing pin located at the interval of the circuit board and the metal inner surface layer it Between, and arc extinguishing pin is vertically fixed on metal inner surface layer, the metal inner surface layer is provided with multiple equally distributed arc extinguishing pins, The metal inner surface layer ground connection, when the electronic devices and components on circuit board produce electric arc, is directly absorbed by arc extinguishing pin, and passes through institute State metal inner surface layer ground connection to carry out extinguishing arc, be prevented effectively from the electronic devices and components that electric arc is burnt on circuit board, it is a large amount of so as to save Resource and cost.

Preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all at this Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in this utility model Protection domain within.
