A kind of PCBA board measurement jig
Technical field
The present invention relates to a kind of measurement jig, be specifically related to a kind of PCBA board measurement jig, belong to electronic components test tool field.
Background technology
PCB(Printed Circuit Board, printed circuit board (PCB)) be important electronic unit, being the supporter of electronic component, is the supplier of electronic devices and components connection.Because it adopts terahertz wave quasi-optics to make, therefore be called as " printing " circuit board.Before printed circuit board occurs, the interconnection between electronic component is all rely on electric wire directly connect and form complete circuit.PCBA is the abbreviation of English Printed Circuit Board+Assembly, that is PCB hollow plate part on SMT, then through the whole processing procedure of DIP plug-in unit, in brief, PCBA board is exactly welded, assembled the pcb board of electronic component.PCBA board after having manufactured needs to test its function such as power unit, port, PCBA board to be measured and model is compared, to determine that whether it is qualified.
Due to PCBA board fine structure, putting into measurement jig, need to pick and place conveniently, and obtain suitable fixing, ensure that, in test process, PCBA board is not rocked, uniform force, indeformable not impaired with element, in addition, the corresponding measurement jig of the previous PCBA board of order, after needing to test a PCBA board, change next PCBA board again, so repeat down, repetitive is too frequent, efficiency is lower, need to manufacture more measurement jig simultaneously, bring very large cost pressure to enterprise, and cause the waste of resource.
Summary of the invention
For solving the deficiencies in the prior art, the object of the invention is to the defect overcoming prior art, a kind of PCBA measurement jig is provided, when PCBA board is placed in measurement jig, pick and place conveniently, PCBA board is not rocked, reliable and stable, structure is simple, easy to use, and N number of PCBA board can be put in a measurement jig.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of PCBA board measurement jig, comprise the rectangular parallelepiped tool of base plate, upper cover plate, backboard, front apron composition, it is characterized in that, also comprise: support column, support plate, board slot, described support column is arranged on described base plate, for supporting described upper cover plate, described support plate is arranged on described base plate, described board slot correspondence is opened in the top of described support plate, and described board slot is opened on described upper cover plate, and the limit of described board slot side adjacent with described front apron can move horizontally.
Aforesaid a kind of PCBA board measurement jig, is characterized in that: described support plate has N number of, is evenly distributed on described base plate, and described board slot number is identical with described support plate number, and is evenly opened in one to one on described upper cover plate with described support plate.
Aforesaid a kind of PCBA board measurement jig, is characterized in that: the load plane of described support plate is consistent with the length and width of described board slot.
Aforesaid a kind of PCBA board measurement jig, is characterized in that: the number of described support plate and described board slot is all 6.
Aforesaid a kind of PCBA measurement jig, is characterized in that: described support column has 4.
Aforesaid a kind of PCBA measurement jig, is characterized in that: the thickness of described backboard is less than the thickness of described front apron.
Aforesaid a kind of PCBA measurement jig, is characterized in that: be provided with 2 backing plates bottom described rectangular parallelepiped tool.
Usefulness of the present invention is: PCBA board measurement jig of the present invention, when PCBA board is placed in measurement jig, pick and place conveniently, in testing process, PCBA board can not be rocked, uniform force, reliable and stable, structure is simple, easy to use, meanwhile, in a PCBA board measurement jig, N number of PCBA board can be put simultaneously, for a PCBA board measurement jig, can, wherein in 1 PCBA board test process, put other PCBA board, elongate repetitive, improve testing efficiency, decrease the manufacture quantity of tool, saving resource, reduce enterprise cost.

The implication of Reference numeral in figure: 1, board slot, 2, front apron, 3, upper cover plate, 4, backboard, 5, base plate, 6, support plate, 7, support column, 8, backing plate.
Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
See Fig. 1 to Fig. 4, of the present inventionly comprise base plate 5 at PCBA board measurement jig, upper cover plate 3, backboard 4, the rectangular parallelepiped tool that front apron 2 forms, and support column 7, support plate 6, board slot 1, support column 1 is arranged on base plate 5, for supporting upper cover plate 3, support plate 6 is arranged on base plate 5, board slot 1 correspondence is opened in the top of support plate 6, board slot 1 is opened on upper cover plate 3, in order to pick and place conveniently when PCBA board is placed into measurement jig, the limit of board slot 1 side adjacent with front apron 2 can move horizontally, moving horizontally of the limit of board slot 1 side adjacent with front apron 2, well can fix the position of PCBA board in measurement jig, reach PCBA board in testing process and can not rock effect.Meanwhile, identical for width, the PCBA board that length is different, also can test on this measurement jig.
In order to submit testing efficiency to, reduce the manufacture quantity of measurement jig, saving resource and reduction enterprise cost, the support plate 6 of PCBA measurement jig of the present invention has N number of, is evenly distributed on base plate 5, board slot 1 number is identical with support plate 6 number, and be evenly opened in one to one on upper cover plate 3 with support plate 6, like this for a PCBA board measurement jig, wherein 1 PCBA board is in the process of acceptance test, put the PCBA board that other are to be measured, elongate repetitive.
During for ensureing PCBA board acceptance test, uniform force, indeformable, element is not impaired, and the load plane of support plate 6 is consistent with the length and width of board slot 1.Certainly, one of the length and width of the load plane of support plate 6 or length and width all can be greater than board slot 1 length and width.
In order to saving resource, reduce enterprise cost, the thickness of backboard 4 is less than the thickness of front apron 2.
Preferred as one, the number of support plate 6 and board slot 1 is all 6.
Preferred as one, support column 7 has 4.
Further, bottom rectangular parallelepiped tool, be provided with 2 backing plates 8, play the effect of buffering and convenient carrying.
More than show and describe ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
