Description
Technical field
The utility model relates to technical field of electronic components, especially a kind of fastening type pcb board.
Background technology
PCB(Printed Circuit Board), Chinese is printed circuit board, and also known as printed circuit board (PCB), printed substrate, being 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, if crimping aperture excessive, then easily cause loose contact or bond strength inadequate; If crimping aperture is too small, then easily occurs that crimping pin cannot be pressed into crimping hole smoothly and cause the problems such as the bending of pin, directly affect stable connection and the service behaviour of components and parts.
Utility model content
Low in order to overcome existing pcb board crimping precision, components and parts connect unstable, and affect the deficiency of service behaviour, the utility model provides a kind of fastening type pcb board.
The utility model solves the technical scheme that its technical problem adopts: a kind of fastening type pcb 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, conductive layer is provided with cover plate, and cover plate is made up of bezel ring, cover plate and cap bore.
According to another embodiment of the present utility model, comprising cover plate is further elastic metal sheet, is welded on the upper surface of conductive layer by bezel ring.
According to another embodiment of the present utility model, comprising cover plate further has four, around the inner ring being distributed in bezel ring, in structure of caving in.
According to another embodiment of the present utility model, comprise the central authorities that cap bore is positioned at cover plate further.
According to another embodiment of the present utility model, comprise the top that cover plate covers crimping hole further, the axis of cap bore is consistent with the axis in crimping hole.
The beneficial effects of the utility model are, weld by bezel ring, above the crimping hole of conductive layer, the cover plate of the elastic metallic material of cover plate and cap bore composition, cover plate has four, around the inner ring being distributed in bezel ring, in structure of caving in, cap bore is positioned at the central authorities of cover plate, play the effect guiding and locate, during use, only crimping hole need be arranged to the larger aperture in prescribed limit, to avoid insertion impaired, when press-fiting, first the crimping pin of components and parts inserts cap bore, then take advantage of a situation and insert crimping hole, the extruding that cover plate is subject to crimping pin produces elastic deformation, cave in further, simultaneously from surrounding clamping crimping pin, structure is not only firm but also tight, and the cover plate after caving in forms inverse toothing, can effectively prevent crimping pin from skidding off crimping hole, substantially increase the stability that components and parts connect, ensure that the normal work of components and parts.
