Description

Technical Field

[0001] The utility model belongs to the field of communication, and particularly relates to an improved structure of a butterfly laser optical fiber welding piece with high yield, high production efficiency, low welding difficulty and high product strength. Background Art

[0002] Fiber welding parts for butterfly lasers (such as Figure 3 The arc is used to weld optical fibers. The inner diameter of the arc is 0.9 mm. A 0.88 mm metal tube is placed in the arc for welding. The metal tube is easily deformed and shrunk during processing. There is a large gap on both sides of the metal tube after it is placed. Welding is difficult and it is easy to have a cold weld or welding failure. The welding efficiency is low, the labor intensity is high, the labor cost is high, the yield rate is low, the width is only 1.45 mm, and there are few welding positions, such as Figure 3 There are only four of them, and the strength of the welded product is low and cannot effectively meet the use requirements.

[0003] The technical problem to be solved by the utility model is to provide an improved structure of a butterfly laser optical fiber welding part which has low welding difficulty, high operating efficiency, low labor intensity, low labor cost, high yield rate, multiple welding positions, good product strength and effectively meets the use requirements. Utility Model Content

[0004] In order to solve the problems of the above-mentioned prior art metal tube having a large gap on both sides after being placed, great difficulty in welding, easy occurrence of cold welding or failure to weld, low welding efficiency, high labor intensity, high labor cost, low yield rate, only 1.45mm width, few welding positions, low strength of welded products, and failure to effectively meet the use requirements, the utility model adopts the following technical solutions:

[0005] The utility model provides an improved structure of a butterfly laser optical fiber welding piece, comprising an inverted U-shaped main welding tube and a pair of external ears, wherein the pair of external ears are symmetrically arranged on both sides of the main welding tube, the inner diameter of the arc of the main welding tube is 0.88 mm, and the width of the main welding tube is 2.9 mm.

[0006] The beneficial effects of the utility model are: after the inner diameter becomes 0.88, the gap on both sides is small, the welding difficulty is small, the operation efficiency is high, the labor intensity is small, the labor cost is low, the yield rate is high, the width is increased to 2.9mm, many welding positions can be used, the product strength is good, and the use requirements are effectively met.

[0009] Figure 3 This is a schematic diagram of the structure of a traditional product. DETAILED DESCRIPTION

[0010] The preferred embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0011] See also Figure 1 , Figure 2 An improved structure of a butterfly laser optical fiber welding part comprises an inverted U-shaped main welding tube 1 and a pair of outer ears 2, wherein the pair of outer ears 2 are symmetrically arranged on both sides of the main welding tube 1. The arc inner diameter of the main welding tube 1 is 0.88 mm, and a metal tube with an outer diameter of 0.88 can be placed therein even if it has slight deformation and shrinkage, and the gap between the two sides is very small after placement, so the welding difficulty is small and the welding efficiency is high. The width of the main welding tube 1 is 2.9 mm. Figure 2 It can be seen that there are 8 weldable positions, and the product strength is good after welding.

[0012] The beneficial effects of the utility model are: after the inner diameter becomes 0.88, the gap on both sides is small, the welding difficulty is small, the operation efficiency is high, the labor intensity is small, the labor cost is low, the yield rate is high, the width is increased to 2.9mm, many welding positions can be used, the product strength is good, and the use requirements are effectively met.

[0013] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
