Abstract
The invention relates to the technical field of an electronic component, and especially relates to an anti-loosening circuit board. The anti-loosening circuit board comprises a substrate, installation holes, a conductive layer, an insulation layer, a heat dissipation layer and crimping holes. The installation holes are distributed at the periphery of the substrate, the conductive layer, the insulation layer and the heat dissipation layer are successively arranged at the upper layer, the middle layer and the lower layer of the substrate, the crimping holes are arranged in the conductive layer, the crimping holes are internally provided with reverse teeth, and the reverse teeth is provided with blades and springs. During press mounting, crimping pins of a component are inserted into slits between reverse teeth at two sides, the blades at a front end are extruded to shrink back so as to spare channels for the crimping pins, the reverse teeth inclined downwards facilitates insertion of the crimping pins, and when the crimping pins are inserted into the bottom, the blades stretch forwards under the effects of the springs to cut into the surface of the crimping pins so as to enable the reverse teeth arranged in a staggered mode to apply asymmetric clamping forces to the crimping pins, such that loosening and inclining can be prevented, the crimping pins can be prevented from retreating and slipping out of the crimping holes, and disengagement during welding is avoided.
Description
Technical field
The present invention 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.
Summary of the invention
Rocking inclination to overcome the insertion of existing circuit board crimping pin, easily causing welding the deficiency come off, the invention provides a kind of locking circuit board.
The technical solution adopted for the present invention to solve the technical problems is: 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 invention, comprise inverse teeth directional further to have a down dip and be connected to the inwall both sides in crimping hole.
According to another embodiment of the invention, comprise the inverse space of teeth distribution of crimping both sides, hole further, be staggered.
According to another embodiment of the invention, comprise the front end of blade sleeve at inverse tooth further, be connected with inverse tooth by spring.
According to another embodiment of the invention, Spring Card is comprised further between blade and inverse tooth.
The invention has the beneficial effects as follows, inverse tooth is set in crimping hole, and blade and spring are set 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 present invention is further described.
