Abstract
The utility model discloses an antistatic and anti-surge PCB structure, which comprises a base plate and a circuit layer printed on the base plate, four metal outgoing lines with zigzag front ends are electrically connected on the circuit layer, scolding tin is coated on the tip of the zigzag end of each metal outgoing line, the tips of zigzag end of every two metal outgoing lines are oppositely arranged, and the spacing of two opposite tips is 2mm-5mm. The antistatic and anti-surge PCB structure employs metal outgoing line with a proper creepage distance, the scolding tin is coated on the tip, the creepage distance between two metal outgoing lines is used, the voltage at two ends of surge current and inductance discharges from two opposite tips to air, the design has the advantages that the design is simple, large current can be discharged, the antistatic effect is good, and performance of electronic product can be greatly increased.
Description
Technical field
The utility model relates to pcb board technical field, is specifically related to the PCB structure of a kind of antistatic, surge.
Background technology
The function of its antistatic of existing pcb board, surge is all to realize by relevant filter element or pressure cell; in the less application scenario of some volume requirements; for example common mode inductance volume is larger for some element; cannot use; or use the protection component of small size; but the impact of the large electric current of unable to bearing, useful life is short.
Utility model content
The utility model provides the PCB structure of a kind of antistatic, surge, can address the above problem.
The PCB structure of a kind of antistatic that the utility model embodiment provides, surge, comprise: basal plate and be printed on the circuit layer on basal plate, on circuit layer, being electrically connected with four front ends is jagged metal lead-out wire, each metal lead-out wire scribbles scolding tin at its jagged tip, the jagged tip of every two metal lead-out wires is oppositely arranged, and two relative most advanced and sophisticated spacing are 2mm～5mm.
Each metal lead-out wire front end extends the discharge metal sheets that a width is greater than metal lead-out wire width, and discharge metal sheets front end is provided with described jagged tip.
Preferably, the position that metal lead-out wire is connected with discharge metal sheets is provided with jack.
Preferably, the width of discharge metal sheets is 3 times of metal lead-out wire width.
Technique scheme can be found out, because the utility model embodiment adopts the jagged electric discharge lead-out wire of suitable creepage distance, and coat scolding tin at place, tip, utilize two creepage distances between zigzag lead-out wire, make the high pressure at surge current, inductance two ends from two relative tips to AB Air Bleed, its design is a little, simplicity of design, the larger electric current of can releasing, anti-static effect is good, has improved greatly the performance of electronic product.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation that the utility model embodiment metal lead-out wire is oppositely arranged.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides the PCB structure of a kind of antistatic, surge, pcb board structure comprises basal plate and is printed on the circuit layer on basal plate, concrete PCB structure forms, and those skilled in the art can be known by existing PCB making sheet technology, PCB structure be repeated no more herein.
As shown in Figure 1, on circuit layer, being electrically connected with four front ends is jagged metal lead-out wire 1, in order further to increase the effect of antistatic, surge, in the present embodiment, each metal lead-out wire 1 front end extends the discharge metal sheets 11 that a width is greater than metal lead-out wire width, discharge metal sheets 11 front ends are provided with described jagged most advanced and sophisticated 12, in the present embodiment, the width H3 of discharge metal sheets 11 is 3 times of width H2 of metal lead-out wire 1, this width ratio makes metal lead-out wire front end release electrostatic or surge current and high pressure fast, and material cost is held moderate; Each metal lead-out wire scribbles scolding tin at its jagged tip, and this scolding tin not only can be fixed on tip on pcb board, but also can guarantee that static discharges the conducting to air; The jagged tip of every two metal lead-out wires is oppositely arranged, and two relative most advanced and sophisticated spacing H1 are 2mm～5mm, and in the present embodiment, this relative most advanced and sophisticated spacing H1 is 3.5mm, has better static releasing effect.
In order to increase the applicability of the PCB structure of antistatic in the present embodiment, surge, the position that metal lead-out wire 1 is connected with discharge metal sheets 11 is provided with jack 2, this jack can insert chip or component pin, for having, need the chip of electrostatic defending or element, this pin inserts this jack, can realize the effect of electrostatic defending.Be appreciated that, metal lead-out wire and circuit layer are electrically connected, for the circuit structure of any product, it is printed on formed circuit layer on pcb board, and the metal lead-out wire in the present embodiment is all accessible, for example the voltage input end at circuit board accesses this metal lead-out wire, the primary side of transformer and secondary side access this metal lead-out wire all can, for concrete circuit, connect, those skilled in the art can be according to requirement of shelter, connect voluntarily design, differ one herein for example.
A kind of antistatic above the utility model embodiment being provided, the PCB structure of surge are described in detail, applied specific case herein principle of the present utility model and execution mode are set forth, the explanation of above embodiment is just for helping to understand core concept of the present utility model; , for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model meanwhile.
