Abstract
The utility model relates to the technical field of LEDs, and especially relates to an LED lead frame which comprises a technology edge, and lead frame units which are arranged side by side. Each lead frame unit comprises a plurality of LED pin leads which are perpendicular to the technology edge. The bottom of each LED pin lead is connected to the technology edge. The pin leads are connected together through an upper connecting rib which is parallel to the technology edge. The length of each LED pin lead is from 46mm to 75mm. According to the utility model, the lengths of the LED pin leads are long enough. Therefore, the LED pin leads have enough lengths, so that a prepared LED lamp can be directly connected through the LED pin leads in a plugging connection manner with no additional need of wiring for connection when a circuit board is far or the LED lamp needs to be embedded into plastic. The LED frame provided by the utility model is convenient to use, can be applicable to long-distance plugging connection, and is wide in application range.
Description
technical field:
The utility model relates to LED technical field, relates in particular to a kind of LED lead frame.
background technology:
It is outstanding that LED luminous product has advantages of is energy-conservation, emission response time is short, the life-span is long, volume is little etc.LED illumination has the wealthy range of application of very bright distant view and factory, and oneself is in being widely used in automotive lighting, guidance lighting and decorative lighting at present.LED lead frame is the supporting part of LED, and international market demand amount increases day by day.Manufacture for gadget lead frames such as LED mainly contains two kinds, and one is for to manufacture lead frame by etching, and another kind is to manufacture lead frame by punching press.For the latter, because it is directly by cold stamping shaped, there is process velocity fast, the feature that structural strength is high.Be generally to adopt coiled strip, through continuous punching, make lead frame piece, then divide and cut into single lead frame.
The length that is at present the LED pin leads on the LED lead frame made of existing punching press is all within the scope of 19 ~ 38mm, the LED lamp of making thus when circuit board hypertelorism, maybe need to be embedded in plastic cement in time, LED pin leads falls short of, cannot pass through the direct socket connection of LED pin leads, need in addition wiring again to connect, use inconvenience, the scope of application is little.
utility model content:
The purpose of this utility model be exactly the deficiency existing for prior art and provide a kind of can be suitable for long apart from socket connection, LED lead frame easy to use.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of LED lead frame, it includes technique edges, a plurality of lead frame unit being arranged side by side, each lead frame unit includes the many LED pin leads vertical with technique edges, the bottom of every LED pin leads is connected on technique edges, between LED pin leads, by upper the connect muscle parallel with technique edges, connect, the length of LED pin leads is 46 ~ 75mm.
Preferably, the length of described LED pin leads is 51 ~ 61mm.
More preferably, the length of described LED pin leads is 58mm.
The width of described LED pin leads is 0.5mm.
Distance between adjacent two lead frame unit is 7.62mm.
Described technique edges and upper company between muscle are provided with at least one and connect muscle, and every LED pin leads is all connected with the middle muscle that connects.
Described middle even muscle is two.
The described upper convex protuberance that is provided with in position that muscle is positioned at one or both sides, lead frame unit that connects.
LED pin leads in each lead frame unit is 2 or 3.
The utility model beneficial effect is: the utility model includes technique edges, a plurality of lead frame unit that are arranged side by side, each lead frame unit includes the many LED pin leads vertical with technique edges, the bottom of every LED pin leads is connected on technique edges, between LED pin leads, by upper the connect muscle parallel with technique edges, connect, the length of LED pin leads is 46 ~ 75mm, the length long enough of the utility model LED pin leads, the LED lamp of making thus when circuit board is distant, maybe need to be embedded in plastic cement in time, LED pin leads has enough length, can pass through the direct socket connection of LED pin leads, and do not need in addition wiring again to connect, easy to use, can be suitable for long apart from socket connection, the scope of application is large.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model lead frame unit.
Fig. 3 is the structural representation of another execution mode of the utility model.
embodiment:
Below in conjunction with accompanying drawing, the utility model is further described, see shown in Fig. 1 ~ 2, a kind of LED lead frame, it includes technique edges 1, a plurality of lead frame unit 2 that are arranged side by side, each lead frame unit 2 includes the many LED pin leads 21 vertical with technique edges 1, the bottom of every LED pin leads 21 is connected on technique edges 1, between LED pin leads 21, by upper the connect muscle 3 parallel with technique edges 1, connect, the length of LED pin leads 21 is 46 ~ 75mm, be preferably 51 ~ 61mm, 58mm more preferably, the length long enough of the utility model LED pin leads 21, the LED lamp of making thus when circuit board is distant, maybe need to be embedded in plastic cement in time, LED pin leads 21 has enough length, can pass through the direct socket connection of LED pin leads 21, and do not need in addition wiring again to connect, easy to use, can be suitable for long apart from socket connection, the scope of application is large.
Distance between adjacent two lead frame unit 2 is 7.62mm.Upper even muscle 3 is positioned at the convex protuberance 5 that is provided with in position of 2 one or both sides, lead frame unit.LED pin leads 21 in each lead frame unit 2 is 2 or 3.
As shown in Figure 3, as another execution mode of the utility model, different from a upper execution mode, technique edges 1 and upper connect to be provided with between muscle 3 in two, connect muscle 4, every LED pin leads 21 all with in two, connect muscle 4 and be connected, increase structural strength.
Certainly, the above is only preferred embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
