Description
Technical field
The utility model relates to circuit board, particularly relates to a kind of double-sided PCB being provided with fairlead and overcoat.
Background technology
Circuit board is for fixing electronic devices and components and the plank be electrically connected in electrical equipment.China Patent No. be 2015203357241, Authorization Notice No. is CN204733458U, name is called in the patent document of " a kind of on-deformable printed circuit board (PCB) " and namely discloses a kind of circuit board.The basic structure of circuit board comprises circuit board body, and the surface of circuit board body is provided with circuit.Double-sided PCB only arranges circuit in the side of circuit board body, and double-sided PCB then all arranges circuit in the both side surface of circuit board body.In order to the pin of supplied for electronic components and parts inserts, as China Patent No. be 2011200082107, Authorization Notice No. is CN201947534U, name to be called in the patent document of " a kind of high after footpath than multilayer board " namely disclosed, need to arrange the through insert hole to circuit board body on the line.During use, the pin of components and parts is inserted from one end away from circuit of insert hole, then by scolding tin, pin is welded together with circuit.
Existing circuit has the following disadvantages: components and parts extracted power time, stress point is all positioned at the junction of pin with circuit, easily produces electrical connection bad phenomenon; Patency when inserting grafting is poor; Circuit is easily damaged and produces electric fault.
Utility model content
The utility model provide a kind of unobstructed when inserting components and parts, circuit can be prevented to be destroyed and to produce the double-sided PCB being provided with fairlead and overcoat of electric fault, solve patency difference when existing circuit board inserts components and parts and the easy impaired problem of circuit.
Above technical problem is solved by following technical proposal: a kind of double-sided PCB being provided with fairlead and overcoat, comprise circuit board body, the tow sides of described circuit board body are all provided with circuit, described circuit is provided with the insert hole of through described circuit board body, it is characterized in that, also comprise the protective layer covering described circuit and circuit board body, the position of the corresponding described insert hole of described protective layer is provided with via hole, the position that described circuit is provided with described insert hole is exposed to described via hole, described insert hole is provided with guide ring away from one end of described circuit, the inner peripheral surface of described guide ring is the conical surface that the little outer diameter of inner diameter is large.During use, the pin of components and parts is inserted insert hole and outlet line through wire sleeve, owing to arranging, there is the fairlead that inner peripheral surface is the conical surface, pin can be inserted swimmingly.Owing to being provided with protective layer, therefore circuit and circuit board body are not easy to be damaged.
As preferably, be interference fit between described guide ring and insert hole.Can easily and effectively prevent guide ring from deviating from from insert hole.
As preferably, described guide ring is provided with the flexible retaining pin preventing the pin of the electric elements be plugged in insert hole from extracting from the one end away from circuit.When inserting pin, pin makes retaining pin open and produces and dodge.Resistance when then the increase of retaining pin is extracted when extracting, thus make pin be not easy to be pulled out, change the grafting problem that easy generation electrical contact that is that cause is bad with stress point between circuit board is single, play the effect improving electrical connection reliability.
As preferably, described retaining pin is arranged at the inner face of described guide ring.Can tin overlap aperture less time carry out layout, improve convenience during circuit-board laying-out.
As preferably, described retaining pin is positioned on the same conical surface along the medial surface of the radial direction of guide ring and the inner peripheral surface of described guide ring.Easy to make, compact conformation.
As preferably, described circuit board body is provided with deposits hole, described protective layer be provided be contained in described in deposit connector in hole.The connection reliability of protective layer can be improved.
As preferably, described in deposit the inner aperture area large outer end opening area in hole little, deposit in hole described in described connector is connected to.Connection reliability is better.
The utility model has following advantage: smoothness when inserting grafting is good; Circuit is not easy to be damaged.
