Description
Technical field
The utility model is related to a kind of LED technology fields, refer specifically to a kind of LED lead with collision prevention function
Frame.
Background technology
LED luminous products have the advantages that energy saving, emission response time is short, long lifespan and small etc. prominent, thus
It is widely used on illumination, instruction, display and decorative product.LED lead frame is to produce the mating portion of LED in batches
Point, LED lead frame is made of multiple LED lead frame units, and each LED lead frame unit has L
ED lamp caps, LED pipe foot lead, technique edges and upper even muscle composition.It is existing for the ease of the chip needed for mounted LED lamp head
The LED lamp holder of LED lead frame unit be all that one boss is set at the top of every LED pipe foot lead, described convex
Chip is installed in the plane of platform.All it is by LED lead frame and LE in being production process or sales process
D leadframes units are stacked or superposition bundles, when adjacent two panels LED lead frame and two adjacent LEDs
When leadframes unit is stacked or is superimposed, wherein the boss of a piece of LED lamp holder will be hit on another LED lamp holder boss
Chip leads to the wafer damage on LED lamp holder boss or comes off.
Invention content
In order to solve the problems, such as more than technology, the utility model provides a kind of in the increasing of LED lamp holder boss bottom
It sets up defences and hits crystalline substance, to limit adjacent two panels LED lamp holder boss distance close to each other, to prevent adjacent two panels LED lamp holder boss from touching
Hit mutual chip.
The utility model includes technique edges and the multiple LED lead frame units for being arranged in technique edges top, Yi Jilian
It is connected on the upper even muscle of LED lead frame unit.
The LED lead frame unit includes the LED pipe foot lead for being mutually parallel and being connect with technique edges top, if
Put the LED lamp holder at the top of LED pipe foot lead.
The LED lamp holder includes being arranged on boss at the top of LED pipe foot lead, mounted on boss surface chip and
It is arranged on boss and the anticollision of LED pipe foot lead junction both sides is brilliant.
The anticollision crystalline substance is arranged on the bottom of boss and the front and rear sides of LED pipe foot lead.
The width of the anticollision crystalline substance is more than the difference of the width and LED pipe foot lead of chip.
The height of the anticollision crystalline substance is more than the height of chip.
The good effect of the utility model is：It can effectively prevent LED lead frame and LED lead frame list
For member when close to each other, the boss on a LED lead frame unit scratches another LED lead frame unit boss
On chip.
Description of the drawings
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the structure chart of the utility model.
Fig. 2 is the utility model LED lead frame cellular construction figure.
Fig. 3 is the utility model LED lead frame unit construction profile.
Fig. 4 be the boss of the utility model LED lead frame unit close to the anticollision crystalline substance upper limit when structure chart.
Fig. 5 be the boss of the utility model LED lead frame unit close to anticollision crystalline substance lower limit when structure chart.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings,
As shown in Figure 1, the utility model is a kind of LED lead frame with collision prevention function.
As shown in Figure 1, the utility model includes technique edges 1 and the multiple LED lead frames for being arranged in 1 top of technique edges
Frame unit 2 and the upper even muscle 3 for being connected to LED lead frame unit 2.As shown in Fig. 2, the LED lead frame list
Member 2 includes the LED pipe foot lead 21 for being mutually parallel and being connect with 1 top of technique edges, is arranged on 21 top of LED pipe foot lead
LED lamp holder 22.As shown in figure 3, the LED lamp holder 22 includes being arranged on the boss 222 at 21 top of LED pipe foot lead, it is mounted on
The chip 221 on 222 surface of boss and the anticollision crystalline substance 223 for being arranged on boss 222 and 21 junction both sides of LED pipe foot lead.Institute
It states anticollision crystalline substance 223 and is arranged on the bottom of boss 222 and the front and rear sides of LED pipe foot lead 21.The width of the anticollision crystalline substance 223
More than the difference of the wide and LED pipe foot lead 21 of chip 221.The height of the anticollision crystalline substance 223 is more than the height of chip 221.
As shown in Figures 4 and 5, in batch package LED lead frame unit 2, when left side LED lead frame unit
2 close to the right LED lead frame unit 2 when, since the anticollision crystalline substance 223 of the right LED lead frame unit is to boss 222
The distance at edge is less than the distance outside the edge to chip of the boss 222 of left state's LED lead frame unit, on the right L
Under the blocking of the anticollision crystalline substance 223 of ED leadframes units, the boss 222 of the right LED lead frame unit can not be close to right
Chip at the top of the LED lead frame unit boss of side.When the boss of left side LED lead frame unit is along the right LE
The brilliant 223 surface slide downwards of the anticollision of D leadframes units, when sliding into the position of Fig. 5, left side LED lead frame unit
Boss displacement branch on the right of LED lead frame unit anticollision crystalline substance lower limit when, the boss of the right LED lead frame unit
222 are already higher than the napex of the chip of left side LED lead frame unit, therefore will not be formed and wound or break showing for chip
As.
