Embodiment
Below in conjunction with accompanying drawing the utility model is done further to set forth.
With reference to shown in Figure 1; First kind of embodiment that the utility model provided is a kind of circuit-board connecting structure; Described syndeton comprises single layer board 1 and double-layer circuit board 2, also is fixed with connecting plate 4 on the single layer board 1, and interconnects through row's pin 3 between double-layer circuit board 2 and the single layer board 1; And respective connecting contacts on an end and the single layer board 1 of row's pin 3, is fixedly coupled on the other end and the single layer board 1 that respective connecting contacts on the plate 4.
Preferred as the utility model the foregoing description; Pass through row's pin 3 connection stability each other for guaranteeing double-layer circuit board 2 and single layer board 1; Refer again to shown in Figure 1; Preferably above-mentioned connecting plate 4 is fixed near the center of single layer board 1, and the through hole that is complementary with connecting plate 4 is arranged on the single layer board 1, connecting plate 4 is fixed in the through hole.On the basis of aforementioned techniques scheme; The inventor of the utility model has also done following improvement; Being specially described connecting plate 4 is welded in the through hole on the single layer board 1; And the inboard of through hole contacts on the both sides of connecting plate 4 and the single layer board 1, by such assurance connecting plate 4 and one way circuit board 1 contact each other, guarantees two smooth conductings of circuit module that their tops connect through this syndeton.
After above-mentioned improvement in many ways; Can be used as the basic embodiment and a comparatively preferred embodiment of the utility model; And because circuit board interconnection technique field is ripe relatively; The inventor also on the technical scheme basis of the foregoing description, has done following improvement with the utility model with reference to prior art; Can be with it as the embodiment that the utility model the foregoing description is more preferably, concrete preferred feature is: described connecting plate 4 adopts soldering to connect in the through hole that is fixed on the single layer board 1.Described connecting plate 4 also is a double-layer circuit board.And aforesaid technical characterictic can make up with any one above-mentioned embodiment of the utility model, thereby becomes a plurality of embodiment that the utility model is the basis with the utility model.
On the basis of the foregoing description; The utility model provides another kind of embodiment also is provided; This embodiment is specially a kind of circuit board method of attachment, and the circuit-board connecting structure described in the utility model the foregoing description is adopted in described method of attachment, operates according to following steps:
Steps A, connecting plate temporarily is fixed near the through hole the center of single layer board;
Step B, will arrange pin an end and double-layer circuit board on respective connecting contact, the other end gets near the through hole the single layer board center, and with through hole in connecting plate on respective connecting contact;
Step C, be the relevant position that the center rotates to needs welding with near the through hole that is provided with its center with single layer board; And with the flanked of through hole on the position of connecting plate side band copper and the single layer board after touch, again connecting plate and single layer board are welded as a whole.
The processing method of the above-mentioned connecting plate of mentioning is circuit and welding position that drafting on PCB needs, and that on PCB, draws needs the place, welding position to hole again, and at last PCB is cut from bore position, promptly forms the connecting plate of side band copper.Respective connecting contacts on row's pin one end among the described step B and the double-layer circuit board, the other end simultaneously with connecting plate on after respective connecting contacts, the two ends that will arrange pin again are welded on respectively on double-layer circuit board and the connecting plate in the respective connecting.Also need to prove: describedly be welded as soldering welding.
Need to prove that also in the custom circuit design, the circuit module with difference in functionality designs separately usually, then different functional is connected.Such as a bulb, it be divided into drive part and luminous component, the drive part major function is that country's power supply is converted into the needed electric current and voltage requirement of luminous component, connect through middle then, with the required voltage current delivery to luminous component.It is exactly to be the described syndeton of the utility model that this middle interconnecting piece divides.The purpose of this utility model is the accuracy rate that guarantees welding, improves packaging efficiency, avoids failure welding, and it is attractive in appearance not influence product simultaneously.
Above-mentioned several embodiment of the utility model compared with prior art also have following difference, and the firstth, the number of welds of syndeton is the same with the welding lead or the number of welds of insert row pin.The secondth, production efficiency is improved, if adopt lead to connect, the time of welding is exactly the time and the summation of distinguishing the wire bonds position time of welding to every lead separately.If adopting winding displacement to connect the needed time is that welding two ends row's seat adds that the row of a distinguishing direction inserts the summation of the time of winding displacement.The 3rd is that raising is mentioned in the contact performance aspect of lead; Winding displacement is to connect through the mode of contact rather than the mode of welding; Relatively badly such as temperature or change under the bigger situation, contact point just has loosening possibility, so just influences efficient in environmental condition.And the utility model is to connect through the mode of welding, and is affected by environment little.The 4th is that the correctness of welding is improved, and the correctness of lead mainly is through manual work every circuit to be distinguished, if wrong possibility of intersecting with regard to bonding wire.The correctness of winding displacement mainly is corresponding through the direction of the direction of row's seat and winding displacement.To judge the direction of row's seat in the time of welding earlier, judge the direction of winding displacement then.And the utility model can be confirmed direction through the profile of connecting plate, and is one corresponding if differ in double-layer circuit board and the pad connecting hole position on the single layer board, just can't weld, and so just eliminated the possibility that welding intersects fully.
In addition; What also need describe is; " embodiment " who is spoken of in this manual, " another embodiment ", " embodiment ", etc., refer to the concrete characteristic, structure or the characteristics that combine this embodiment to describe and be included among at least one embodiment that the application's generality describes.A plurality of local appearance statement of the same race is not necessarily to refer to same embodiment in specification.Further, when describing a concrete characteristic, structure or characteristics in conjunction with arbitrary embodiment, what institute will advocate is that other embodiment of combination realize that this characteristic, structure or characteristics also drop in the scope of the utility model.
Although a plurality of explanatory embodiment with reference to the utility model is described the utility model here; But; Should be appreciated that; Those skilled in the art can design a lot of other modification and execution modes, and these are revised and execution mode will drop within disclosed principle scope of the application and the spirit.More particularly, in the scope of, accompanying drawing open and claim, can carry out multiple modification and improvement to the building block and/or the layout of subject combination layout in the application.Except modification that building block and/or layout are carried out with improve, to those skilled in the art, other purposes also will be tangible.
