Abstract
The utility model discloses a lens bracket, which consists of a bottom board and a side board. An angle B formed between the bottom board and the side board is within 105 DEG C-115 DEG C. When in use, the bottom board is welded with a lug boss of a substrate and the side edge thereof is welded with a shell of the lens. The connecting thickness between the substrate and the lens bracket in the structure is increased, which greatly improves intensity and rigidity of products, integration is uneasy to become deformed, and contact area between the lens bracket and the substrate is small; the utility model is easy to be welded and fixed and is uneasy to be deformed after welded; besides, the bracket can support the lens firmly, has good product quality and high precise dimension and conquers a defect of low yield in the prior art.
Description
Technical field
The utility model relates to a kind of optical communication product, particularly a kind of lens carrier, and main effect is that lens supports is fixed on the substrate, makes the light that chip sent on the substrate pass through Lens Coupling in optical fiber.
Background technology
Shown in Fig. 5,6: the section of existing lens carrier 3 is " U " font, and weld mutually with lens 2 outsides both sides of the edge of support 3, and the bottom of support 3 is plane and is seated on the substrate 5 and welds fixing mutually with substrate 5.This constructed products shortcoming is as follows: be difficult for processing, if the welding technology in the assurance fixation procedure is stable, what work in-process just must guarantee that the bigger bottom surface of support can be very smooth is attached on the substrate, will guarantee also that simultaneously the dual-side of support is vertical, promptly vertical with the bottom surface, the size of support is less, minimum dimension only is 0.15 millimeter, in order to satisfy above-mentioned requirements, will carry out the strictness screening after machine work, cause the yield rate of this link very low, increased production cost; In welding process, the welding at support bottom surface and substrate contacts position is unusual difficulty, and it requires very strict to operating angle of the focus head of laser-beam welding machine, and the technological requirement during to welding is also high, welding energy is bigger, can make solder joint excessive, and make the support burn through and cause coming off or being out of shape, welding energy is smaller, cause failure welding, cause coming off, focus point skew slightly during the welding contraposition all may cause welding result that big variation takes place.Because the shape of support, the thickness of substrate is difficult for excessive, and thin substrate causes the stability of support not high.
Summary of the invention
The purpose of this utility model provides the lens carrier of a kind of handling ease, good operation, not yielding, good stability, overcomes the deficiencies in the prior art.
Lens carrier of the present utility model is characterized in that: lens carrier is made up of base plate 7 and side plate 6, and angulation B is between 105 °～115 ° between described base plate 7 and the side plate 6.
Lens carrier of the present utility model, angulation B is between 108 °～112 ° between wherein said base plate 7 and the side plate 6.
Lens carrier of the present utility model, angulation B is 110 ° between wherein said base plate 7 and the side plate 6.
Lens carrier of the present utility model is structure as a whole between wherein said base plate 7 and the side plate 6.
Lens carrier of the present utility model, because lens carrier is made up of base plate 7 and side plate 6, between angle B between 105 °～115 °, during use, the dual-side of substrate 5 is provided with the boss 4 of symmetry, between lens 2 and each boss 4, be welded with lens carrier 3, the base plate 7 of forming lens carrier 3 welds mutually with boss 4, the side plate 6 that levers up welds mutually with lens 2, and substrate 5 increases with support 3 joint thickness, and strength and stiffness improve greatly, product integral body is not yielding, lens carrier 3 is little with substrate 5 contacted areas, and welding is fixing easily, and postwelding also is difficult for deforming, support is firm to the support of lens, good product quality, the dimensional accuracy height has overcome the low defective of yield rate in the prior art.

Embodiment
Shown in Fig. 1,2,3,4: 5 is substrate, is provided with luminescence chip 1 above a termination of substrate 5.Be furnished with lens 2 mutually with luminescence chip 1, lens 2 are supported on the substrate 5, and the light that chip 1 is sent is coupled in the optical fiber through lens 2.Syndeton between lens 2 and the substrate 5 is: the dual-side at substrate 5 has the symmetrical boss that raises up 4, and boss 4 is into a single integrated structure with its plate 5.On each boss 4, be welded with lens carrier 3, lens carrier 3 is made up of base plate 7 and the side plate 6 that joins with it, be structure as a whole between base plate 7 and the side plate 6, outward appearance is the shape of bending, base plate 7 after the bending and substrate 5 welding, side plate 6 coboundarys after the bending and the welding of the outside of lens 2, the base plate 7 of lens carrier 3 and the included angle B between the side plate 6 are 105 ° or 108 ° or 110 ° or 112 ° or 115 °, promptly all can between 105 °～115 °.
Claims (4)
