Abstract
The utility model belongs to the technical field of the electronic components technique and specifically relates to a locking 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 against the tooth, is equipped with blade and spring on the contrary tooth. During the pressure equipment, go into the gap between the contrary tooth in both sides with the crimping cushion of components and parts, the blade of front end receives the extrusion and shrinks back, vacates the passageway for the crimping needle, and the contrary tooth of downward sloping is convenient for crimping cushion and is gone into, and when crimping cushion on earth after, the blade protracts under the effect of spring, cuts into the surface of crimping needle, and asymmetric clamping -force is applyed to the crimping needle to messenger staggered arrangement's contrary tooth, not only can prevent to become flexible, can prevent the crimping needle to retreat roll -off crimping hole moreover, drops when avoiding welding.
Description
Technical field
The utility model relates to technical field of electronic components, especially a kind of locking 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, fixed mechanism useless, and crimping pin inserts in crimping hole and easily rocks, and tilts, and easily causes coming off when welding.
Utility model content
Rock inclination to overcome the insertion of existing circuit board crimping pin, easily cause welding the deficiency come off, the utility model provides a kind of locking circuit board.
The utility model solves the technical scheme that its technical problem adopts: a kind of locking 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, be provided with inverse tooth in crimping hole, inverse tooth is provided with blade and spring.
According to another embodiment of the present utility model, comprise inverse teeth directional further and have a down dip and be connected to the inwall both sides in crimping hole.
According to another embodiment of the present utility model, comprise the inverse space of teeth distribution of crimping both sides, hole further, be staggered.
According to another embodiment of the present utility model, comprise the front end of blade sleeve at inverse tooth further, be connected with inverse tooth by spring.
According to another embodiment of the present utility model, comprise Spring Card further between blade and inverse tooth.
The beneficial effects of the utility model are, in crimping hole, arrange inverse tooth, and arrange blade and spring on inverse tooth, form pretension locking gear.When press-fiting, the crimping pin of components and parts is inserted both sides against the gap between tooth, the blade of front end is squeezed and shrinks back, for passage vacateed by crimping pin, downward-sloping inverse tooth is convenient to crimping pin and is inserted, when after crimping cushion on earth, blade protracts under the action of the spring, the surface of incision crimping pin, staggered inverse tooth is made to apply asymmetrical chucking power to crimping pin, not only can prevent from loosening, and the retrogressing of crimping pin can be stoped to skid off crimping hole, avoid coming off during welding.
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;
Fig. 2 is inverse tooth schematic diagram 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. against tooth, and 8. blade, 9. spring.
Embodiment
If Fig. 1 is structural representation of the present utility model, Fig. 2 is inverse tooth schematic diagram of the present utility model, a kind of locking 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, and conductive layer 3, insulating barrier 4 and heat dissipating layer 5 are sequentially arranged in the upper, middle and lower of substrate 1, and crimping hole 6 is opened on conductive layer 3, be provided with inverse tooth 7 in crimping hole 6, inverse tooth 7 is provided with blade 8 and spring 9.The downward-sloping inwall both sides being connected to crimping hole 6 of inverse tooth 7.The inverse tooth 7 of crimping both sides, hole 6 is spaced apart, is staggered.Blade 8 is enclosed within the front end of inverse tooth 7, is connected with inverse tooth 7 by spring 9.Spring 9 is stuck between blade 8 and inverse tooth 7.
Inverse tooth 7 is set in crimping hole 6, and blade 8 and spring 9 are set on inverse tooth 7, form pretension locking gear.When press-fiting, the crimping pin of components and parts is inserted both sides against the gap between tooth 7, the blade 8 of front end is squeezed and shrinks back, for passage vacateed by crimping pin, downward-sloping inverse tooth 7 makes crimping pin easily enter difficulty to go out, when after crimping cushion on earth, blade 8 protracts under the effect of spring 9, the surface of incision crimping pin, staggered inverse tooth 7 is made to apply asymmetrical chucking power to crimping pin, not only can prevent from loosening, and the retrogressing of crimping pin can be stoped to skid off crimping hole, avoid coming off during welding.
