Abstract
The utility model discloses a kind of novel counter sink for composite circuit board, including circuit board main body, blind slot hole, silicon rubber loop, circuit board main body logicalnot circuit region is provided with several blind slot holes；The blind slot hole includes the first counter sink above blind slot hole, positioned at blind slot hole bottom and perpendicular to the threaded hole of circuit board main body, below the first counter sink and be connected to the second counter sink of threaded hole；The first, second counter sink junction in blind slot hole is arranged in the silicon rubber loop.By the way that silicon rubber loop is arranged at blind slot counter sink, silicon rubber loop inner wall has screw thread identical with threaded hole, and silicon rubber loop has certain elasticity, further latches screw, make screw it is more firm be placed in blind slot hole.Flexible silicon rubber loop is alternatively arranged as buffer system, and screw is effectively prevent to pierce too deep damage circuit board main body.
Description
Technical field
The utility model belongs to circuit board mounting technique field, and in particular to a kind of novel countersunk head for composite circuit board
Hole.
Background technique
Currently, printed wiring board for electronic equipment, generally takes and designs counter sink on printed circuit substrate, with spy
Wiring board is linked at electronic equipment internal by fixed screw.
And the countersunk head pore structure that traditional fixed form uses is single straight-through countersunk head pore structure, after fastened by screw just
It submerges counter sink or screw horizontal plane is slightly above wiring board plane, it is not close after this traditional fixed form screw is fixed,
It is easy to happen loosening, the firmly wiring board excessive also easy to damage when installing screw.And part metals screw terminal can protrude product table
Face can also cause to be powered with the exception of external circuit structure in special circumstances, and there are security risks.
Utility model content
To solve the problems mentioned above in the background art, the utility model provides a kind of for the new of composite circuit board
Type counter sink keeps the fixation of screw more firm.
To achieve the above object, the utility model provides the following technical solutions:
A kind of novel counter sink for composite circuit board, including circuit board main body, blind slot hole, silicon rubber loop, the electricity
Road plate main body logicalnot circuit region is provided with several blind slot holes；The blind slot hole includes the first counter sink above blind slot hole, is located at
Blind slot hole bottom and perpendicular to the threaded hole of circuit board main body, below the first counter sink and be connected to the second countersunk head of threaded hole
Hole；The first, second counter sink junction in blind slot hole is arranged in the silicon rubber loop.
Preferably, first counter sink, the second counter sink in the blind slot hole are truncated cone-shaped hole, and the threaded hole is cylinder
Shape hole, inner wall have specific screw thread.
Preferably, the concyclic axis axle center of the first counter sink, the second counter sink, threaded hole in the blind slot hole.
Preferably, the silicon rubber loop is torus, and inner wall has screw thread identical with threaded hole inner wall.
Preferably, the silicon rubber loop inner wall radius is greater than threaded hole inner wall.
Compared with prior art, the utility model has the beneficial effects that
By the way that silicon rubber loop is arranged at blind slot counter sink, silicon rubber loop inner wall has screw thread identical with threaded hole, and
Silicon rubber loop has certain elasticity, further latches screw, make screw it is more firm be placed in blind slot hole.With elasticity
Silicon rubber loop be alternatively arranged as buffer system, effectively prevent screw to pierce too deep damage circuit board main body.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1-3, the utility model the following technical schemes are provided:
A kind of novel counter sink for composite circuit board, including circuit board main body 1, blind slot hole 2, silicon rubber loop 3, circuit
1 logicalnot circuit region of plate main body is provided with several blind slot holes 2；Blind slot hole 2 includes 2 the first counter sink 4 of top of blind slot hole, positioned at blind
2 bottom of slot and perpendicular to the threaded hole of circuit board main body 16, positioned at the lower section of the first counter sink 4 and be connected to the second of threaded hole 6
Counter sink 5；First counter sink 4 in blind slot hole 2,5 junction of the second counter sink is arranged in silicon rubber loop 3.Threaded hole 6 and silicon rubber
The inner thread of circle 3 is identical, can be made corresponding screw thread by machining to different screws.
Screw is vertically pierced toward blind slot hole 2, since 3 inner wall of silicon rubber loop is slightly larger than 6 inner wall of threaded hole, silicon rubber loop
3 can generate axial thrust to screw, further latch screw, finally pierce completely to screw, keep screw more firm
Be placed in blind slot hole 2.When screw pierces completely, carriage bolt bottom is contacted with silicon rubber loop 3, and silicon rubber loop 3 produces carriage bolt
Raw upward thrust, 6 inner thread of threaded hole generate downward frictional force to screw, consolidate screw in threaded hole 6, and
Silicon rubber loop 3 can prevent carriage bolt and circuit board contacts, have certain buffer capacity, further prevent circuit board damage.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
