Abstract
The utility model discloses a material strip of LED lead rack, comprising a metal material strip provided with a first lead frame which is provided with a first lead rack, a second lead frame which is disposed on the metal material strip and adjacent to the first lead frame and is provided with a second lead rack, and at least two connecting parts which are respectively disposed between the first lead frame and the second lead frame and are connected to the metal material strip. As the two connecting parts correspond to each other with a gap in between, and the first lead rack is connected to the second lead rack through the two connecting parts, the utility model is advantageous in that the distance between each lead frame on the metal material strip can be shortened; the lead frame can be arranged in a more compact way on the metal material strip; the utilization ratio of material and production power is improved; the waste of raw material is prevented.
Description
Technical field
The utility model is a kind of material-strap structure of LED lead frame, is meant especially a kind ofly can shorten the spacing between each lead frame on the metal material belt, makes its lead frame be arranged more intensive material-strap structure on metal material belt.
Background technology
As shown in Figure 1, be the schematic diagram of the material-strap structure of an existing lead frame.As shown in the figure, this material-strap structure mainly is that a metal material belt A is provided with a plurality of lead frame B, respectively be provided with a lead frame C in each lead frame B, wherein has a junction D respectively between each lead frame B, the two ends of this connecting portion D are connected on the metal material belt A, generally are a H type, and central authorities have a connecting rod E, its each lead frame C sees through those connecting portions D to interconnect fixingly, and its each lead frame C is fixed on this metal material belt A.
But, above-mentioned this each lead frame C sees through the connecting portion D that generally is the H shape to be connected, so, on connecting portion D, formed a connecting rod E, but because of lead frame C is a superfine little product, and limited by stamping technology, so the width of connecting rod E is restricted, makes this connecting rod E must keep a suitable width.
So, make the width that must be reserved with connecting rod E on this metal material belt A, make the spacing between its each lead frame B, can't shorten, cause metal material belt A to go up too much unnecessary material of reservation, and significantly reduced the stock utilization of metal material belt A, also significantly reduced product competitiveness, simultaneously more caused raw-material waste, the cost of its lead frame C can't effectively be reduced.
So above-mentioned or the like problem is the technical problem that the utility model institute desire solves, so the utility model mainly is to address the above problem, and makes more intensive that its lead frame is able to arrange on metal material belt, and then promotes raw-material utilance, reduces cost.
The utility model content
Main purpose of the present utility model is to provide a kind of and can shortens the spacing between each lead frame on the metal material belt, makes its lead frame be arranged the material-strap structure of more intensive LED lead frame on metal material belt.
For reaching above-mentioned purpose, technical characterictic of the present utility model is to include a metal material belt: one first lead frame, be located on the metal material belt, and have one first lead frame on it; One second lead frame is located on the metal material belt adjacently with first lead frame, has one second lead frame on it; And at least two connecting portions, to be located at respectively between first lead frame and second lead frame, and to be connected with metal material belt, two connecting portions are corresponding but do not join and be formed with a gap, make first lead frame see through this two connecting portion and second lead frame interconnects.
With this, the beneficial effect that the utlity model has is: shortened the spacing between each lead frame on the metal material belt, it is more intensive that its lead frame is arranged on metal material belt, with the raising material and the rate of capacity utilization, and can avoid raw-material waste.
Above-mentioned and other purpose, advantage and characteristic of the present utility model are more understood in depth by the detailed description and the referenced in schematic of following preferred embodiment.

Embodiment
Please refer to shown in Figure 2, floor map for the material-strap structure of the utility model LED lead frame, it comprises a metal material belt 10, at least two lead frames 20 (in graphic be example with ten lead frames 20, the scope of its each lead frame 20 is represented by dotted lines) and at least two connecting portions 30.Wherein:
Two connecting portions 30, be located at 22 of first lead frame 21 and second lead frames respectively, and be connected with metal material belt 10, two connecting portions 30 are corresponding but do not join, therebetween and be formed with a gap 31, second lead frame 26 that first lead frame 23 on first lead frame 21 is seen through on two connecting portions 30 and second lead frame 22 interconnects.
Please consult shown in Figure 3ly simultaneously, be schematic perspective view of the present utility model.As shown in the figure, two connecting portions 30 are formed with a card protuberance 32 respectively adjacent to an end of first lead frame 21 and second lead frame 22, and this card protuberance 32 is embedded in respectively in first lead frame 23 and second lead frame 26; And on first lead frame 23 and second lead frame 26 with respect to the card projection 32 the position, be provided with the card projection 32 corresponding draw-in grooves 29 with two connecting portions 30, card projection 32 on two connecting portions 30 is embedded in respectively in the draw-in groove 29 on first lead frame 23 and second lead frame 23.
With this, first lead frame 23 is able to interconnect by two connecting portions 30 and second lead frame 26, so can shorten the spacing between first lead frame 21 and second lead frame 22 on the metal material belt 10, make its each lead frame 20 be able on metal material belt 10, arrange more intensive, and then reach the purpose that improves the material and the rate of capacity utilization, and can avoid raw-material waste, significantly reduce production costs.
The specific embodiment that in the detailed description of preferred embodiment, is proposed, only in order to be easy to illustrate technology contents of the present utility model, be not with the utility model narrow sense be limited among the embodiment, all following of situations according to spirit of the present utility model and claim scope are made many variations and are implemented, and all belong to scope of the present utility model.
