Description

High-strength PC B jigsaw

Technical field

The utility model relates to a kind of PCB jigsaw, particularly a kind of high-strength PC B jigsaw that can effectively increase linking intensity between each veneer.

Background technology

The PCB jigsaw is PCB that some have been designed single edition, and group is lined up as a whole galley.

In general, in the present various electronic products, produce in batches for ease like the pcb boards such as automatically controlled circuit, part mobile phone and digital product of energy-saving lamp electronic ballast, electronic toy, the method that all can adopt veneer to be combined into a big jigsaw is produced.But because the shape of PCB veneer exists each species diversity; Conventional method is the appearance profile according to the PCB veneer when jigsaw; Draw a V-type groove and cut apart with opening with the punching out hole, this method tends to produce the hole less with area, the bigger hole of some areas (the PCB jigsaw like the PCB veneer composition of energy-saving lamp electronic ballast often just has bigger hole and less hole to exist together) according to appearance profile production of PCB veneer; Cause the limit that connects between the PCB veneer too small if go out the bigger hole of area; The linking intensity of monoblock PCB jigsaw will variation so; Such PCB jigsaw is in each road production process such as follow-up paster, plug-in unit, crest welding, detection; Big through regular meeting's deformation that bends, and broken easily fracture, bigger economic loss caused.

The utility model content

The technical problem that the utility model will solve provides a kind of high-strength PC B jigsaw that can effectively increase linking intensity between each veneer.

In order to solve the problems of the technologies described above, the utility model provides a kind of high-strength PC B jigsaw, comprises the PCB jigsaw of being made up of several PCB veneers; Be equipped with in described PCB jigsaw outer periphery and enclose frame; Described PCB veneer is provided with hole and following hole; For any two neighbouring PCB veneers, the following hole of the PCB veneer above being positioned at is combined to form a macroscopic cavitation with the last hole of the PCB veneer that is positioned at the below; Enclose frame and be provided with the automatic error device; Be provided with stiffener in the said macroscopic cavitation, the two ends of stiffener are fixedly connected with said two PCB veneers respectively.

As the improvement to the utility model high-strength PC B jigsaw: described stiffener is middle wide, flat that two ends are narrow.

As the further improvement to the utility model high-strength PC B jigsaw: the edge of said PCB veneer is provided with two-sided V-shaped groove; Described two-sided V-shaped groove is by combining at positive front V-shaped groove of PCB veneer and reverse side V-shaped groove at PCB veneer reverse side.

As the further improvement to the utility model high-strength PC B jigsaw: described automatic error device is at the location hole that encloses the asymmetric setting in the frame left and right sides.

In the high-strength PC B jigsaw of the utility model,,, that is to say the material cost that does not increase the PCB jigsaw so do not have the area of extra increase pcb board material because stiffener is arranged on the inside, macroscopic cavitation of PCB jigsaw; Owing to increased the connection area between each veneer; So improved the compression strength of PCB jigsaw; The situation of deformation, broken fracture of bending during the various components and parts of full load greatly reduces, and efficient is high when producing, product qualified rate is also high thereby make, and can produce favorable economic benefit.

Embodiment

Embodiment 1, Fig. 1～Fig. 4 combines to have provided a kind of high-strength PC B jigsaw, comprises that forming specification by 24 PCB veneers 2 is 4 * 6 PCB jigsaw 1, and the periphery of PCB jigsaw 1 is with frame 7; PCB veneer 2 is provided with hole 11 and following hole 12, between two neighbouring arbitrarily PCB veneers 2, through

last hole

11 and 12 composition macroscopic cavitations 4, following hole (macroscopic cavitation 4 is the maximum holes of PCB jigsaw 1 inner area); Between two adjacent PCB veneers 2 of any left and right sides; Be equipped with little hole II 9; Between four adjacent up and down arbitrarily PCB veneers 2, be equipped with little hole I 8 (little hole I 8 promptly is two less holes of PCB jigsaw 1 inner area with little hole II9, and the less hole of area does not have influence to the compression strength of PCB jigsaw 1); The width that encloses frame 7 is 5mm, around PCB jigsaw 1 one circles; More than be prior art, the also same prior art of its method for using.

Be provided with stiffener 5 in the macroscopic cavitation 4 recited above, stiffener 5 is the flat that the centre is wide, two ends are narrow, and the two ends of stiffener 5 are fixedly connected with two PCB veneers 2 respectively and are integral.The edge of every PCB veneer 2 is provided with two-sided V-shaped groove 6, and two-sided V-shaped groove 6 is by combining at positive front V-shaped groove 13 of PCB veneer 2 and reverse side V-shaped groove 14 at PCB veneer 2 reverse side; Be provided with the automatic error device on the frame 7 enclosing; The automatic error device is at the location hole that encloses the frame asymmetric setting in the 7 left and right sides (diameter in hole >=4mm); Be exactly specifically to establish a location hole II 32 enclosing frame 7 upper left corners; A location hole III33 is established in the lower left corner, encloses centre position, frame 7 right side and establishes a location hole I 31.

Above-described PCB veneer 2 is the PCB veneer of electric ballast in the spiral 20W electricity-saving lamp.

The actual production step of high-strength PC B jigsaw is following:

1, plate-making:

Choose the pcb board material of suitable dimension.

2, punching:

2.1, when punching, in the macroscopic cavitation 4 of last hole 11 and following hole 12 compositions, stay a stiffener 5;

2.2, little hole I 8 and the method punching out of little hole II 9 by routine.

3, automatic error device (location hole of the diameter >=4mm in hole):

3.1, dash a location hole II 32 in frame 7 upper left corners of enclosing of PCB jigsaw 1, the lower left corner dashes a location hole III33;

3.2, dash a location hole I 31 in the centre position, frame 7 right side of enclosing of PCB jigsaw 1.

4, cut groove (groove depth be pcb board thickness 1/4th):

Opening in the edge of PCB veneer 2 to draw has two-sided V-shaped groove 6, and the two-sided V-shaped groove 6 of some transversely arranged PCB veneers 2 is formed horizontal straight line, and the two-sided V-shaped groove 6 of the some PCB veneers of vertically arranging 2 is formed vertical straight line; Enclosing on the frame 7, be easy operation, can open and draw corresponding two-sided V-shaped groove 6, thus convenient when separating PCB veneer 2, reduce the unnecessary material that brings owing to overexerting and scrap.

5, steps such as paster, plug-in unit, crest welding and detection are all with reference to the existing conventional method.

6, practicality:

6.1, separating PCB veneer 2: only need gently just break into two with one's hands can (because two-sided V-shaped groove 6, thus separation the time, easier; Stiffener 5 is the flat that the centre is wide, two ends are narrow, because the place, two ends is narrow, can produces stress and concentrate, and makes the residual again easily body of separation less, can not influence follow-up assembling);

6.2, the method for using of PCB veneer 2 is with reference to the existing conventional method.

At last, it is also to be noted that what more than enumerate only is a specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought the protection range of the utility model.
