Abstract
The utility model relates to an electrostatic discharge structure for printed circuit boards (PCB), which comprises three copper foils and a power supply terminal, wherein one copper foil is positioned on one side of the other two copper foils, the three copper foils are not connected to one another, and one copper foil is positioned on the side close to the power supply terminal. The PCB electrostatic discharge structure has the advantages of simple structure and short discharge channel, is suitable for electrostatic short-circuit in any form, works normally in a strong electrostatic field, and greatly improves the use safety of the electronic product.
Description
Technical field
The utility model relates to a kind of PCB electro-static discharge structure.
Background technology
Owing to have certain electric charge in human body and the air, when staff touches product, the electric charge that air and human body produce will enter into product thereupon, if do not allow the path of its charge discharging resisting, its electric charge will be run helter-skelter in product, be damaged to electronic component, cause the product can't the operate as normal or the lost of life.The structure of the static discharge path that existing on the market electronic product is provided with is loaded down with trivial details, and path is oversize, and middle by a lot of elementary parts, when static is big, elementary part will be shocked by electricity and damages.
The utility model content
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art and a kind of PCB electro-static discharge structure is provided.
Technical solutions of the utility model are:
The PCB electro-static discharge structure, include: Copper Foil 1, Copper Foil 2, Copper Foil 3, supply terminals 4, described Copper Foil 1, Copper Foil 2 are positioned at a side of described Copper Foil 3, do not link to each other mutually between Copper Foil 1, the Copper Foil 2, described Copper Foil 3 is positioned at the side near supply terminals 4, has a groove 6 that disconnects between Copper Foil 1, Copper Foil 2 and the Copper Foil 3.
All be respectively equipped with at least three discharge tip 5 on Copper Foil 1, Copper Foil 2 and the Copper Foil 3.
The utility model is simple in structure, and discharge path is short, is applicable to that any type of static scurries the road, and discharge path is by elementary part, and the discharging efficiency height all can operate as normal under very strong static, has improved the safety in utilization of electronic product greatly.

Fig. 2 application switch power supply discharging structure figure.
Embodiment
Below in conjunction with figure the utility model is further specified.
As shown in Figure 1, the PCB electro-static discharge structure, include: Copper Foil 1, Copper Foil 2, Copper Foil 3, supply terminals 4, described Copper Foil 1, Copper Foil 2 are positioned at a side of described Copper Foil 3, do not link to each other mutually between Copper Foil 1, the Copper Foil 2, described Copper Foil 3 is positioned at the side near supply terminals 4, has a groove 6 that disconnects between Copper Foil 1, Copper Foil 2 and the Copper Foil 3.All be respectively equipped with three discharge tip 5 on Copper Foil 1, Copper Foil 2 and the Copper Foil 3.When static entered in the product, this structure can form the static discharge path of Copper Foil 1---Copper Foil 2---Copper Foil 3---supply terminals rapidly, and static is imported power net rapidly, prevented that static from running helter-skelter and damage product.
Described three blocks of Copper Foils are with the shortest static discharge loop of the formation of power-supply system, are suitable for any type of static to scurry, and the static that enters in the product can be imported rapidly and efficiently in the power-supply system, prevent that static from running helter-skelter and damage product.
As shown in Figure 2, the Switching Power Supply operational module is by elementary input system, and rectifying and wave-filtering system, transformation voltage-stabilizing system and direct current output system are formed, and when not having static to scurry, whole system all can operate as normal.Because static normally enters from the slit of product, so the most frequent electrostatic interference is to enter from elementary equipped at outlet port, then runs helter-skelter between each system.When no static discharge path or the static discharge path is oversize and when arriving supply terminals again and be power net zero L of live wire system, N through elementary part, working part is easy to damage.When using this discharging structure, the static discharge path directly by secondary quick importing power net zero L of live wire system, N place, can not run helter-skelter between each working part, guarantees product safety work use.
Repeat embodiment, its difference is can have on the Copper Foil discharge tip more than three.
