Abstract
Disclosed is a direct inset type LED support, comprising a plurality of parallelly connected racks, wherein each rack comprises an area A and an area B, with the area A arranged above the area B; the area A and the area B are respectively a functional area and a non-functional area; the rack is provided with a silver coating with the thickness ranging from 0.5 to 2 microns at the external surface of the area A and provided with a tin coating with the thickness ranging from 1 to 2 microns at the external surface of the area B; and the ratio of the vertical length of the area A to that of the area B is 1 to 2.5-4.5. According to the utility model, the silver coating is only arranged at the functional area, thereby saving the silver consumption and reducing the cost. The non-functional area is provided with a tin coating, thereby improving the product yield and the quality of the finished product and effectively solving the problems of dead lamp, deformation, poor tin welding, and the like.
Description
Technical field
The utility model relates to a kind of straight inserting type LED support.
Background technology
LED from the late 1960s discovery so far, luminous efficiency is high because it has, long service life and the advantage such as safe and reliable, obtained studying widely and using, direct insertion LED refers to pin, two one metal wires are namely arranged, need to pass welding to pin from the hole of circuit board during welding, paster directly is welded on circuit board, need not punch on plank, most research at present all concentrates on the LED lamp, and is few to the research of LED lamp support.
Current, for straight inserting type LED support, present product has following two kinds: a kind of is complete silver-plated straight inserting type LED support; Another kind is functional areas half silver-plated straight inserting type LED supports.There is following defective in these two kinds of supports: because the silver-plated Main Function of LED support is to be convenient to beat gold thread, and the zone that need to beat gold thread is only the position of functional areas, the position area of functional areas is very little, and complete silver-plated LED support causes waste because a large amount of nonfunctional area position is silver-plated, increased cost; Functional areas half silver-plated straight inserting type LED support, need to carry out scolding tin after encapsulation connects due to straight inserting type LED support, the not silver-plated meeting in lower end causes scolding tin bad, therefore generally for half silver-plated support, need to roll again rack plating tin after encapsulation, can cause the dead lamp rate of product to increase and cause deformation of products to be unfavorable for later process processing but roll rack plating tin after encapsulation.
The utility model content
The purpose of this utility model is in order to solve existing defective in prior art, provide that a kind of coated metal expends less, the finished product rate and quality improves, can the life-and-death lamp of efficient solution, the straight inserting type LED support of the problem such as distortion, scolding tin be bad.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of straight inserting type LED support, comprise the horse that several connect side by side successively, it is characterized in that, described horse has A district and B district, described A district is on the top in described B district, described horse is provided with the first coating at the outer surface in described A district, and described horse is provided with the second coating at the outer surface in described B district.
Further, the thickness of described the first coating is 0.5～2 μ m.
Further, the thickness of described the second coating is 1 μ m～2 μ m.
Further, described the first coating is silver coating, and described the second coating is tin coating.
Further, the longitudinal length ratio in the longitudinal length in described A district and described B district is 1:(2.5～4.5).
The beneficial effect that the utlity model has: straight inserting type LED support, comprise the horse that several connect side by side successively, horse can be divided into A district and B two, district part by its function, the A district is functional areas, to be connected with the LED lamp, horse is provided with 0.5～2 thick silver coating of μ m at the outer surface in A district, and the metal of silver coating is argent, and is the mode of electroplating by bull wheel; The B district is nonfunctional area, the main connection function that rises, the outer surface of horse in the B district is provided with the tin coating of 1 μ m～2 μ m, and the material of tin coating is metallic tin, be the mode by high-accuracy immersion plating, the longitudinal length ratio in the longitudinal length in described A district and described B district is 1:(2.5～4.5).The utility model is owing to only being provided with silver coating at the functional areas outer surface, if when the silver coating thickness of silver coating thickness and complete silver-plated LED support is identical, can economize on silver 80%; Simultaneously because nonfunctional area is zinc-plated before encapsulation, can improve rate of finished products and the end product quality of product, the problem such as the life-and-death lamp of efficient solution, distortion, scolding tin are bad.
Description of drawings
Fig. 1 is the partial structurtes schematic diagram of straight inserting type LED support;
Fig. 2 is the longitudinal section enlarged drawing of the part of Fig. 1.
Embodiment
Further understand and understanding for making architectural feature of the present utility model and the effect reached are had, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
as shown in Figure 1, a kind of straight inserting type LED support comprises several horses that connects side by side 1, and in the present embodiment, horse 1 always has 25, and the lateral length of whole support is 152.4mm, and the longitudinal length of single horse 1 is 21.5mm, wherein horse 1 has A district and B district, the A district is on the top in B district, continue with reference to shown in Figure 2, the part of horse 1 in the A district, it is an irregular structure, the right and left is respectively negative pole pin and anodal pin, the negative pole pin be connected pin and be used for connect the LED lamp and use, therefore the A district also can be described as functional areas, the part of horse 1 in the B district, be actually the lower end of negative pole pin and anodal pin, main plaing a part connects, therefore the B district also can be described as nonfunctional area, the outer surface of horse 1 in the A district is provided with the first coating 2, the outer surface of horse 1 in the B district is provided with the second coating 3, the thickness of the first coating 2 is 0.5～2 μ m, the thickness of the second coating 3 is 1 μ m～2 μ m, in the present embodiment, the first coating 2 is silver coating, the metal material of silver coating is silver, the mode that silver coating is electroplated by bull wheel plates, the second coating 3 is tin coating, the metal material of tin coating is tin, silver coating is that the mode by high-accuracy immersion plating plates, the thickness of the first coating 2 is 0.5 μ m, the thickness of the second coating 3 is 2 μ m, in addition, the longitudinal length ratio in the longitudinal length in A district and B district is 1:(2.5～4.5), in the present embodiment, this ratio is 1:4.3, the longitudinal length that is the A district is 4mm, the longitudinal length in B district is 17.5mm.
