Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical isolator manufacturing technology, and in particular to a fixture for adjusting the angle and direction of an optical isolator. Background Technology
[0002] The following problems exist in the alignment and adjustment tools of FSI and Receptacle in the traditional optical isolator assembly process: 1. Defects of metal adjustment tools: mismatch in material hardness (5-6 grade stainless steel needle vs 7-8 grade samarium cobalt magnetic ring), magnetic adsorption effect, tool wear, and reduction in adjustment accuracy; 2. Defects of non-metallic tools: insufficient coefficient of friction (0.2-0.3), large adjustment deviation, and risk of organic matter contamination. Utility Model Content
[0003] This invention provides a clamp for adjusting the angle and direction of an optical isolator, which can achieve non-destructive adjustment, is not attracted by the magnetic ring, and produces no debris.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A fixture for adjusting the angle of an optical isolator includes a fixture body made of zirconia ceramic material, which is cylindrical in shape and has one end ground into a conical shape with a curvature radius ≤0.1mm.
[0005] Preferably, the diameter of the clamp body is 1.5-2.5mm and the length is 40-60mm.
[0006] Preferably, the cylindrical portion of the clamp body is provided with anti-slip texture to increase friction.
[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is made of zirconia ceramic material and has the following advantages: high hardness (Mohs hardness 8.5) matches the samarium cobalt magnetic ring (7-8) to achieve damage-free adjustment; high toughness, high bending strength and high wear resistance; oxidation resistance and not adsorbed by the magnetic ring; high toughness, high bending strength and high wear resistance, and no debris is generated. Attached Figure Description
[0008] Figure 1 This is a schematic diagram of the main structure of an embodiment of the present utility model.
[0009] In the diagram: 1. Fixture body. Detailed Implementation
[0010] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0012] like Figure 1 As shown, the present invention includes a clamp body 1, which is made of zirconia ceramic material and is cylindrical in shape, with one end ground into a conical shape with a curvature radius ≤0.1mm.
[0013] The miniaturized assembly of the optical isolator needs to be completed under a stereo microscope: epoxy resin is injected into the Receptacle cavity using a precision dispensing needle, and the FSI and Receptacle are initially positioned by magnetic pole adsorption (initial deviation controlled ≤±90°) to reduce the adjustment angle travel. The fixture body 1 can achieve stable force application by utilizing the inherent frictional resistance of the Receptacle cavity, and the magnetic ring is rotated to achieve the MARK point alignment requirement of ±10° between the FSI and Receptacle, thereby ensuring that the insertion loss index is ≤0.3dB.
[0014] Preferably, the clamp body 1 has a diameter of 2mm and a length of 45mm; the cylindrical part of the clamp body 1 is provided with anti-slip texture, such as masking tape, to increase friction.
[0015] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
