Abstract
The utility model relates to a PCB board, and particularly to a structure shape thereof. The aim of the utility model is to provide the PCB board which is simple for processing, more satisfies the processing requirement and is provided with the stamp hole. According to the PCB board with the stamp hole, the stamp hole which facilitates the separation of edge material is provided between the effective board area and the edge material of the PCB board. The PCB hole is formed by separately connecting an elongated hole and 3-5 small round holes. The small round holes of the stamp hole are deflected to the side of the effective board area relatively to the elongated hole. Two ends of the elongated hole are provided with small bending segments, which are similarly deflected to the side of the effective board area and are arranged colinearly with the positions of the small round holes.
Description
Technical field
The utility model relates to pcb board, relates to its planform especially.
Background technology
Pcb board is exactly a printed circuit board (PCB), almost can appear in the middle of each electronic equipment.And electronic component just is set on the pcb board of different sizes.Along with electronic equipment becomes increasingly complex, the part that needs is more and more, and circuit and part on the pcb board are also more and more intensive.This plate is heat insulation by insulation, also unbending material constitutes substrate, the tiny line material that can see on the surface is a Copper Foil, originally Copper Foil is to cover on the whole plank, and part is etched in manufacture process disposes, and the part that stays has just become netted tiny circuit.These circuits are known as lead or claim wiring, and are used to provide the circuit connection of part on the pcb board.
Usually all be provided with groove between the corner of the actual use of nothing of existing pcb board and effective plate district or the feature board district, when the finished product pcb board pulls open when using along above-mentioned groove, it is outside protruding usually to have stayed burr, not only have a strong impact on the attractive in appearance of pcb board, but also be easy to scratch operating personnel's limbs, the more important thing is to make pcb board be difficult to snap in complete machine.
The utility model content
To be solved in the utility model is that the leftover pieces of pcb board are pulled when effective plate district, the edge of pcb board can stay the burr phenomena of projection, and purpose provides a kind of pcb board with stamp hole simple, can not stay burr when leftover pieces are pulled from effective plate district of processing.
The technical scheme that realizes the utility model purpose is as follows:
Has the stamp hole that separates rim charge after being convenient between a kind of pcb board, effective plate district of above-mentioned pcb board and rim charge with stamp hole.
Above-mentioned stamp hole is connected to form at interval by strip hole and 3-5 small sircle hole.
The small sircle hole of above-mentioned stamp hole is partial to effective plate district one side with respect to strip hole, and the two ends of above-mentioned strip hole have the segment bending, and this segment bending is same is partial to effective plate district side, and distributes with small sircle hole position conllinear.Like this when pulling from rim charge, the small sircle hole section will be partial to effective plate district side with respect to the strip hole section, and pulling from the plane of disruption of small sircle hole place produces projection exactly, fall in to effective plate district owing to the small sircle hole section now, can guarantee the smooth of whole pcb board profile, also can when packing, not hurt employee's limbs.
This novel advantage is to have overcome the pcb board rim charge to pull from being to cause burr uneven, the problem of hurting sb.'s feelings easily again, and also the course of processing is very simple and easy.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
See Fig. 1, the utility model pcb board has stamp hole 1, and this stamp hole becomes wire to distribute, the active zone of pcb board is distinguished with rim charge is isolated, when needs use active zone plate, can along stamp hole with rim charge pull from.
Above-mentioned stamp hole 1 is by strip hole 11 and 3 12 spaced apart compositions of small sircle hole, above-mentioned small sircle hole section is partial to effective plate district with respect to strip hole, and the strip hole two ends have the segment bending 11-1 of the effective plate of deflection district side, above-mentioned segment bending and small sircle hole conllinear, whole like this stamp hole presents polyline shaped, is partial to effective plate district in the small sircle hole section.When needs were pulled from rim charge, the protruding burr that the small sircle hole section forms so can not influence the concordant of this piece pcb board profile, had also prevented that burr from hurting employee's limbs owing to recessed to the inboard.
This novel stamp hole only need mill just and can finish through the brill of disposable punching out of mould or numerically controlled lathe.This connecting filament can not influence the wiring on the pcb board face.
Claims (3)
1. pcb board with stamp hole is characterized in that: have the stamp hole (1) that separates rim charge after being convenient between effective plate district of above-mentioned pcb board and the rim charge.
2. the pcb board with stamp hole according to claim 1 is characterized in that: above-mentioned stamp hole is connected to form at interval by strip hole (11) and 3-5 small sircle hole (12).
3. the pcb board with stamp hole according to claim 2, it is characterized in that: the small sircle hole of above-mentioned stamp hole (12) is partial to effective plate district one side with respect to strip hole, the two ends of above-mentioned strip hole have segment bending (11-1), this segment bending is same is partial to effective plate district side, and distributes with small sircle hole position conllinear.
