Abstract
The utility model belongs to the technical field of the electronic components technique and specifically relates to a firm type 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 offered on the conducting layer, and downthehole counter bore and the interior bushing pipe of being equipped with of crimping is equipped with the cardboard on the interior bushing pipe. During the pressure equipment, the pipeline of interior bushing pipe is the state of tightening up, with the crimping cushion of the components and parts bushing pipe that enters, strut the pipeline, and the inside lining tube swelling, outside side stay is opened, and the chucking is downthehole in trapezoidal crimping to to crimping aciculiform one -tenth clamping action, the one -way cardboard that opens and shuts is passed to the bottom of crimping needle, inserts the counter bore, not only plays the positioning action, is blocked by the cardboard moreover to be difficult to withdraw from, has improved welding quality greatly.
Description
Technical field
The utility model relates to technical field of electronic components, especially a kind of steady 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 during use, crimping pin inserts and loosens, and easily causes loose contact when welding, affects the stable connection of components and parts.
Utility model content
Insert loosening to overcome existing circuit board crimping pin, easily cause loose contact, affect the deficiency of service behaviour, the utility model provides a kind of steady type circuit board.
The utility model solves the technical scheme that its technical problem adopts: a kind of steady 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 counterbore and internal lining pipe in hole, and internal lining pipe is provided with clamp.
According to another embodiment of the present utility model, it is trapezoidal for comprising crimping hole further, and counterbore is positioned at the bottom center in crimping hole.
According to another embodiment of the present utility model, comprising internal lining pipe is further elastic metallic pipe, is embedded in crimping hole.
According to another embodiment of the present utility model, comprising clamp is further unidirectional opening-closing plate, is connected to the two bottom sides of internal lining pipe.
According to another embodiment of the present utility model, comprise the top that clamp is positioned at counterbore further.
The beneficial effects of the utility model are, are designed to trapezoidal by crimping hole, and arrange the internal lining pipe of counterbore and elastic metallic material in crimping hole, arrange clamp simultaneously, form the stable holding mechanism to crimping pin on internal lining pipe.When press-fiting, the crimping pin of components and parts, in the state of tightening up, is inserted internal lining pipe by the pipeline of internal lining pipe, pipeline is strutted, internal lining pipe expands, and struts laterally, is clamped in trapezoidal crimping hole, thus clamping action is formed to crimping pin, the bottom of crimping pin, through the clamp of unidirectional folding, is inserted counterbore, is not only played positioning action, and to be blocked by clamp and be difficult to exit, substantially increase welding quality.
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. counterbore, 8. internal lining pipe, 9. clamp.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of steady 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 counterbore 7 and internal lining pipe 8 in hole 6, and internal lining pipe 8 is provided with clamp 9.Crimping hole 6 is in trapezoidal, and counterbore 7 is positioned at the bottom center in crimping hole 6.Internal lining pipe 8 is elastic metallic pipe, is embedded in crimping hole 6.Clamp 9 is unidirectional opening-closing plate, is connected to the two bottom sides of internal lining pipe 8.Clamp 9 is positioned at the top of counterbore 7.
Crimping hole 6 is designed to trapezoidal, and the internal lining pipe 8 of counterbore 7 and elastic metallic material is set in crimping hole 6, clamp 9 is set on internal lining pipe 8 simultaneously, forms the stable holding mechanism to crimping pin.The crimping pin of components and parts, in the state of tightening up, when press-fiting, is inserted internal lining pipe 8 by the pipeline of internal lining pipe 8, pipeline is strutted, internal lining pipe 8 is expanded, struts laterally, be clamped in trapezoidal crimping hole 6, thus clamping action is formed to crimping pin, the bottom of crimping pin, through the clamp 9 of unidirectional folding, is inserted counterbore 7, is not only played positioning action, and to be blocked by clamp 9 and be difficult to exit, substantially increase welding quality.
