Abstract
The utility model belongs to the technical field of the electronic components technique and specifically relates to a from lock circuit board. It includes base plate, mounting hole, conducting layer, insulating layer, heat dissipation layer and crimping hole, and the mounting hole distributes around the base plate, and upper strata, middle level and lower floor at the base plate are arranged in proper order to conducting layer, insulating layer and heat dissipation layer, and the crimping hole is seted up on the conducting layer, and the crimping is downthehole to be equipped with the latch and to press from both sides the cover, presss from both sides to sheathe in to be equipped with the draw -in groove. Overlap with pressing from both sides at the downthehole latch that sets up of crimping to sheathe in at the clamp and set up the draw -in groove, form automatic locking mechanism. During the pressure equipment, earlier with the crimping cushion of components and parts go into the U -shaped press from both sides the cover in, then to insert the crimping together downthehole together with pressing from both sides the cover, inserts back on earth, the draw -in groove is connected with the latch meshing, realize pressing from both sides overlap with the fixing of crimping hole to closely locking is downthehole in the crimping with the crimping needle, and in order to provide strong support, avoiding the solder joint atress, too big and the fracture prevents effectively that components and parts from dropping.
Description
Technical field
The utility model relates to technical field of electronic components, especially a kind of self-locking type circuit board.
Background technology
Printed circuit board (PCB) is important electronic unit, is the supporter of electronic devices and components, is the supplier of electronic devices and components electrical connection.In prior art, pcb board is widely used, and well-known electronic component can produce heat in the course of the work, so the thermal diffusivity of pcb board is an important index.Crimping hole on existing pcb board is once-forming through hole, and crimping pin does not have retaining mechanism after inserting crimping hole, is welded and fixed by aperture completely, and inner shortage supports, and easily cause solder joint to ftracture, the time has been grown components and parts and easily dropped.
Utility model content
Weak in order to overcome existing circuit board crimping hole support force, easily cause solder joint to ftracture, the deficiency that components and parts drop, the utility model provides a kind of self-locking type circuit board.
The utility model solves the technical scheme that its technical problem adopts: a kind of self-locking type circuit board, comprise substrate, installing hole, conductive layer, insulating barrier, heat dissipating layer and crimping hole, installing hole is distributed in the surrounding of substrate, conductive layer, insulating barrier and heat dissipating layer are sequentially arranged in the upper, middle and lower of substrate, crimping hole is offered on the electrically conductive, crimping is provided with latch and chuck in hole, and chuck is provided with draw-in groove.
According to another embodiment of the present utility model, comprise the both sides, aperture that latch is positioned at crimping hole further.
According to another embodiment of the present utility model, comprising chuck is further elastic metallic cover, and take the shape of the letter U structure.
According to another embodiment of the present utility model, comprise draw-in groove further and be evenly distributed on the outer wall of chuck both sides.
According to another embodiment of the present utility model, comprise latch further and draw-in groove is connected with a joggle.
The beneficial effects of the utility model are, arrange latch and chuck, and arrange draw-in groove on chuck, form automatic locking mechanism in crimping hole.When press-fiting, first the crimping pin of components and parts is inserted in the chuck of U-shaped, then insert in crimping hole together with chuck, after being inserted into the end, draw-in groove and latch are connected with a joggle, and realize chuck and crimp the fixing of hole, thus pin firm locking will be crimped in crimping hole, to provide strong support, avoid solder joint stressed excessive and ftracture, effectively prevent components and parts from dropping.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. substrates, 2. installing hole, 3. conductive layer, 4. insulating barrier, 5. heat dissipating layer in figure, 6. crimp hole, 7. latch, 8. chuck, 9. draw-in groove.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of self-locking type circuit board, comprise substrate 1, installing hole 2, conductive layer 3, insulating barrier 4, heat dissipating layer 5 and crimping hole 6, installing hole 2 is distributed in the surrounding of substrate 1, conductive layer 3, insulating barrier 4 and heat dissipating layer 5 are sequentially arranged in the upper, middle and lower of substrate 1, crimping hole 6 is opened on conductive layer 3, and crimping is provided with latch 7 and chuck 8 in hole 6, and chuck 8 is provided with draw-in groove 9.Latch 7 is positioned at the both sides, aperture in crimping hole 6.Chuck 8 is elastic metallic cover, and take the shape of the letter U structure.Draw-in groove 9 is evenly distributed on the outer wall of chuck 8 both sides.Latch 7 and draw-in groove 9 are connected with a joggle.
Latch 7 and chuck 8 are set in crimping hole 6, and draw-in groove 9 is set on chuck 8, form automatic locking mechanism.When press-fiting, first the crimping pin of components and parts is inserted in the chuck 8 of U-shaped, then insert in crimping hole 6 together with chuck 8, after being inserted into the end, draw-in groove 9 and latch 7 are connected with a joggle, and realize chuck 8 and crimp the fixing of hole 6, thus pin firm locking will be crimped in crimping hole 6, to provide strong support, avoid solder joint stressed excessive and ftracture, effectively prevent components and parts from dropping.
