Abstract
The utility model discloses a static electricity discharge device of a circuit board of a traffic signal instrument. The static electricity discharge device of the circuit board of the traffic signal instrument mainly comprises a metal panel, a protective area, a gas discharge tube and a workplace area, wherein the protective area is connected with the workplace area through a discharge circuit, and the gas discharge tube is arranged on the discharge circuit. Static electricity of the circuit board can be discharged through one way of the protective area, the gas discharge tube and the workplace area, so that the phenomenon that excessive static electricity damages elements in the circuit board can be avoided, and especially, the gas discharge tube can control size of discharge current to protect the circuit board.
Description
Technical field
The utility model relates to field of circuit boards, especially a kind of traffic signals mounted circuit board static electricity discharge device.
Background technology
Because the traffic signals mounted circuit board is very easy to gather static, if electrostatic accumulation is too much, can not in time be released, will easily puncture the electronic component in the circuit board, affect the work of circuit board, cause damage, and invention of the present utility model provides a kind of technology that can leadage circuit plate static, has avoided the appearance of problems.
The utility model content
The purpose of this utility model is to solve weak point of the prior art, and a kind of traffic signals mounted circuit board static electricity discharge device that can leadage circuit plate static is provided.
Technical scheme: for achieving the above object; a kind of traffic signals mounted circuit board static electricity discharge device; it mainly comprises metal decking, Conservation areas territory, gas discharge tube and work region; connect by discharge circuit between described Conservation areas territory and the described work region, at discharge circuit described gas discharge tube is installed.
Described gas discharge tube is installed on the described discharge circuit.
Beneficial effect: the static in the utility model circuit board can be released by this paths of Conservation areas territory, gas discharge tube and work region; thereby assurance the excessive of static caused damage to the element in the circuit board; especially the setting of gas discharge tube, size that can the controlled discharge electric current is come the protection circuit plate.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1, metal decking; 2, Conservation areas territory; 3, gas discharge tube; 4, work region.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
Shown in the figure; a kind of traffic signals mounted circuit board static electricity discharge device; it mainly comprises metal decking 1, Conservation areas territory 2, gas discharge tube 3 and work region 4; connect by discharge circuit between described Conservation areas territory 2 and the described work region 4, at discharge circuit described gas discharge tube 3 is installed.
