Embodiment
Please refer to shown in Fig. 1 to Fig. 7, that show the concrete structure of the preferred embodiment of the utility model, is a kind of LED support of TV backlight, includes positive pole pin 10, negative pole pin 20 and a plastic cement main body 30.This plastic cement main body 30 is square-shaped, itself and positive and negative electrode pin 10,20 integrally produced by insert molding.In the conglobate reflector 31 of top shape of plastic cement main body 30.
Wherein, plates that this positive and negative electrode pin 10,20 size is identical and symmetrical, positive and negative electrode pin 10,20 includes die bond portion 11 that one connects, extension 12 and solder sections 13.The first red ink antiseepage groove 14 is provided with in the front of this extension 12.Bottom surface periphery in this die bond portion 11 is provided with concave station 15, and in concave station 15, be provided with the second red ink antiseepage groove 16.When twice red ink leakage preventing structure can effectively prevent red ink from testing, ink bleed enters interiors of products.
In the present embodiment, the structure of twice red ink leakage preventing structure is as follows:
Described positive and negative electrode pin 10,20 has two the first red ink antiseepage grooves 14 respectively, and this two first red ink antiseepages groove 14 is parallel to each other, all from the side lateral direction penetrating on extension 12 surface to the opposite side of extension 12.Described positive and negative electrode pin 10,20 has three the second red ink antiseepage grooves 16 respectively, wherein a second red ink antiseepage groove and two other second red ink antiseepage texturearunaperpendicular; Wherein second red ink antiseepage groove is from the side lateral direction penetrating of bottom surface, die bond portion 11 to opposite side, and two other second red ink antiseepage groove is longitudinally through to opposite side from the side at two ends, bottom surface, die bond portion 11.Thus, twice red ink antiseepage groove 14,16 is surrounded on the periphery of reflector 31 substantially completely, effectively prevent red ink from infiltrating, in addition, because these red ink antiseepage grooves 14,16 tightly can also bite the plastic cement of plastic cement main body 30, the retain strength between positive and negative electrode pin 10,20 and plastic cement main body 30 therefore can be strengthened.
When positive and negative electrode pin 10,20 and plastic cement main body 30MOLDING shaping after, the bottom surface of this positive and negative electrode pin 10,20 entirety exposes the bottom of plastic cement main body 30.Wherein, the front, die bond portion 11 of this positive and negative electrode pin 10,20 is exposed at the bottom of the cup of reflector 31 to form the identical die bond face of area, make this product to adopt flip chip structure, chip is placed on the centre of reflector, make the light effect reflected than traditional TV support better effects if.The solder sections 13 of this positive and negative electrode pin 10,20 stretches out plastic cement main body 30 both sides, and described concave station 15, first red ink antiseepage groove 14, second red ink antiseepage groove 16 is imbedded in plastic cement main body 30.In addition, the both sides, bottom surface of described extension 12 are provided with concane gap 17, and this concane gap 17 is also imbedded in plastic cement main body 30, and positive and negative electrode pin 10,20 is firmly combined with plastic cement main body 30.
The bottom surface of described positive and negative electrode pin 10,20 is integrally formed with fin 18, thus positive and negative electrode pin 10,20 can with fin 18 at same set of in-mold molding, relative to the radiating copper sheet of traditional separate type, traditional heat-dissipating copper sheet and positive and negative electrode pin respectively need out one set of die, after by radiating copper sheet and positive and negative electrode pin superposition put into plastic mould MOLDING plastic cement main body, the Mould Machining cost of this kind of structure is expensive, mould processing technology is complicated, assembly problem and tolerance value more complicated.And after positive and negative electrode pin 10,20 and fin 18 be set to integral type by this patent, solder sections 13 directly stamping-out and without the need to bending, need the structure of bending scolding tin pin relative to tradition, present Mould Machining expense is low, and mould-forming process is simple.
From size, the LED support height overall 0.8MM of this patent product, the wherein dark 0.4MM of reflector 31.The transverse width of described solder sections 13 equals the transverse width of extension 12, and the transverse width of this extension 12 is less than the transverse width in die bond portion 11.Thus product can make more miniaturized, improve the resolution of TV backlight.
Fig. 8 to 13 shows copper coin material strip 41 process shaping with plastic cement main body 30 MOLDING.This copper coin support 40 has 14 LEDs supports, the spacing between adjacent two LED supports is 5.5MM.Periphery due to LED support is copper coin material strip 41, corresponding every the LED support of this copper coin material strip 41 is provided with 4 V-shaped grooves and gets stuck structure 42, this V-shaped groove structure 42 that gets stuck holds plastic cement main body 30 both sides of LED support, and this design occurs loosening phenomenon after can preventing plastic cement main body 30 and copper coin material strip 41MOLDING.In addition, copper coin material strip 41 outside the solder sections 13 of described LED support has a location hole 43, the both sides of location hole 43 have into glue point 44, the laggard glue point 44 of MOLDING, the V-shaped groove structure 42 that gets stuck is sealed by plastic cement together with plastic cement main body 30, later stage is cut off by blanking again, this structural design can relax the size management and control to the position that gets stuck, and enhances productivity.
In sum, design focal point of the present utility model is, it is mainly owing to being made as circle by reflector 31, and two die bond face sizes in reflector 31 are identical, thus can flip chip structure be used, chip is placed on reflector 31 Themiddle refractive light effect out better than traditional TV support; In addition this product also designs the impermeable line 14,16 of twice red ink, and when effectively preventing red ink from testing, ink bleed is to interiors of products, and conforming product rate effectively improves.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
