Specific embodiment
Below in conjunction with specific embodiment and accompanying drawing, the present invention is described in detail.
A kind of pcb board of LED of the present embodiment, as shown in Figures 2 and 3, its structure separates leading for arrangement including several
Electric piece 2(Conducting strip 2 is used as line unit), the both sides of each conducting strip 2 are provided with connection through hole 21, and the pcb board also includes
The connection unit 3 of the both sides of the adjacent of adjacent two panels conducting strip 2 is located therein respectively, and connection unit 3 is used to connect simultaneously
Two conducting strips 2 of insulated space between adjacent, connection unit 3 uses the plastic material of high-temperature insulation.Specifically, each
Connection unit 3 includes crossbeam 31, and the both ends of crossbeam 31 are provided with and are connected the projection 32 that through hole 21 is engaged, and raised 32 insert
In connection through hole 21, raised 32 can be and be connected the interference fit of through hole 21, strengthen consolidating between two neighboring conducting strip 2
It is fixed.The middle part of crossbeam 31 is provided with separating part 33, in the gap that separating part 33 is absorbed between adjacent two pieces of conducting strips 2, so as to every
Open adjacent two conducting strip 2.Crossbeam 31, raised 32 and the integrated injection molding of separating part 33, it is easy to process.Connection unit 3
The not bottom surface of coated with conductive piece 2, peripheral LED lamp bead unit 1 is arranged on the top surface of adjacent two pieces of conducting strips 2, forms as shown in Figure 1
Structure.Compared with prior art, the pcb board of the present embodiment employs independent multiple connection units 3 in turn multiple
Conducting strip 2 is connected, and forms a lamp bar entirety, and connection unit 3 simultaneously plays a part of to separate, insulate.Therefore, it is possible to
The heat sink 6 and insulation board 7 in traditional PCB plate as shown in Figure 5 is removed, the consumption of heat sink material and insulating materials is reduced, batch
Amount manufacture production cost can be greatly reduced.Bottom surface of the connection unit 3 without coated with conductive piece 2, LED lamp bead unit sheds
When heat is sustained downwards, heat will not be connected unit 2 to be stopped, without through tradition insulation board 6 as shown in Figure 5 and radiating
Plate 7, therefore the radiating effect of the pcb board is good.Conducting strip 2 on the basis of the demand powered as line unit is met, piece
The conducting strip 2 of shape itself can just play good radiating effect.Due to without the need for arranging insulation board and radiating in the bottom surface of conducting strip 2
Plate, the thickness of pcb board is also largely thinning, and by original 10 millimeters about 2 millimeters are thinned to.
In the present embodiment, the pcb board also includes the middleware 36 of insulation, corresponding two between two adjacent conducting strips 2
By the middleware 36 come being connected structure, the both sides stress of such conducting strip 2 connects individual connection unit 3 than more uniform
3 integral structures of order unit are compact, are connected more stable.
Preferably, conducting strip 2 is aluminium flake, and the conducting strip 2 of aluminium material radiates well, and easy to process.Not preferred, lead
Electric piece 2 selects iron plate or copper sheet, either non-preferentially from any one in iron plate, copper sheet or any two kinds of group
Close, the radiating effect of copper or iron is not good enough, and punch process difficulty, than larger, cost is also relatively high.Therefore it is conductive
Piece 2 is optimal selection from aluminium material.
In addition, conducting strip 2 could be arranged to fenestral fabric, radiating effect is more significantly.
In actual manufacture, the technical scheme adjacent two panels conducting strip 2 coupled together using independent connection unit 3 is not only
Only it is suitable in the lamp bar of strip, is also suitable in bulb lamp,(Ball bulb lamp structure is not shown in figure)Specially in the shell of bulb lamp
Multiple conducting strips are installed in inside, and conducting strip is also to be coupled together with independent connection unit, and it is exhausted that connection unit needs high temperature resistant
The performance of edge.Then mounted LED lamp bulb in the same manner, will not be described here.When this bulb lamp uses the technical scheme, by
More much larger than the area of the conducting strip of lamp bar in the area of conducting strip, cancellated conducting strip seems more on heat dispersion
It is important.
The manufacture method of above-mentioned pcb board, comprises the following steps:
1st, material preparation step:Get out the conductive plate substrate of the aluminum of the strip of default specification;
2nd, sidepiece punch steps:The multiple grooves 4 being spaced apart along the length direction of conductive plate substrate are stamped out on base material, such as
Shown in Fig. 4, and connecting portion 5 is left at each groove 4 so that conductive plate substrate is uninterrupted, the base material between two neighboring groove 4
As a conducting strip 2, and the punch forming connection through hole 21 on conducting strip 2;Wherein each groove 4 includes left groove 41 and the right side
Groove 42, left groove 41 and right groove 42 are stamped are molded over the both sides of conductive plate substrate respectively, and connecting portion 5 is located at and does left recessed
Between groove 41 and right groove 42, structure as shown in Figure 4 is formed.Stamped recess 4 can be from the top of the top surface of conducting strip 2 by
On stamp out downwards groove 4, or from the left and right sides of the base material of conducting strip 2 towards the base material of conducting strip 2 middle part punch forming
Groove 4.
3rd, injection step:Injection mo(u)lding connection unit 3 is so as to connect and separates two neighboring conducting strip 2;See Fig. 3 and Tu
4, correspondence left groove 41 is molded with left connection unit 34, and at correspondence right groove 42 right connection unit 35 is molded with.
4th, middle part punch steps:The connecting portion 5 between two conducting strips 2 is washed out, so that two adjacent conducting strips 2 are mutual
Insulation.Connecting portion 5 forms space after being washed out, in the space mould filling so that left connection unit 34 and right connection unit 35
It is integrally formed.Certainly, the space be not filled with can also, LED lamp bead unit 1 produce heat can be sustained by the gap, root
Decide whether filling according to actual demand.
The technological process of above-mentioned pcb board manufacture method is fairly simple, and practical operation is also more convenient.
Finally it should be noted that above example is only illustrating technical scheme, rather than to present invention guarantor
The restriction of shield scope, although having made to explain to the present invention with reference to preferred embodiment, one of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent, without deviating from the reality of technical solution of the present invention
Matter and scope.
