Description

Technical Field

[0001] The utility model belongs to the technical field of sensitive ring component testing, and in particular relates to a sensitive ring component screening and fixing tool. Background Art

[0002] As the core component of the fiber optic gyroscope, the fiber optic sensitive ring assembly plays a direct and vital role in the accuracy of the fiber optic gyroscope. In order to select qualified and stable sensitive rings, each sensitive ring assembly needs to undergo a large number of screening tests. The fiber optic sensitive ring is easily affected by the outside world and is easy to bend and break. The slight wind force and over-current wires during the test will affect the test accuracy of the fiber optic sensitive ring, and the slight stress is very likely to damage the entire valuable fiber optic sensitive ring.

[0003] The current sensitive ring component fixing tooling is extremely lacking in stress protection and photoelectric isolation protection for the sensitive ring component pigtail, and cannot be isolated from the external test environment. The test process is inconvenient to operate and the sensitive ring component is easily damaged due to misoperation. Utility Model Content

[0009] The bottom of each component fixing position (3) is provided with a sensitive ring modulation wire outlet hole leading to the outside of the screening fixing tooling, which can avoid photoelectric interference and facilitate the positioning of the direction of the wire on the sensitive ring component.

[0029] The bottom of each component fixing position (3) is provided with a sensitive ring modulation wire outlet hole leading to the outside of the screening fixing tooling, which can avoid photoelectric interference and facilitate the positioning of the direction of the wire on the sensitive ring component.

[0030] Among them, the tail fibers of each sensitive ring component are independent of each other and isolated from light and electricity.

[0031] The protective cover is provided with a pigtail outlet slot outlet (6), which cooperates with the pigtail outlet slot (1), and the pigtail test end of the sensitive ring assembly is led out from it, thereby reducing the influence of external factors on the sensitive ring assembly and ensuring the stability of the sensitive ring assembly test.

[0032] Wherein, six fixing positions of sensitive ring components are arranged on the base.

[0033] Among them, except for leading the sensitive ring component pigtail test end and the modulation wire out of the internal space of the screening fixed tooling formed by the base and the protective cover, the rest of the screening fixed tooling is inside the internal space of the screening fixed tooling, thereby reducing the impact of external factors on the sensitive ring component during the test process.

[0034] The pigtail outlet slot (1), the optical fiber storage slot (2), the assembly fixing position (3), the pigtail outlet (4), the sensitive ring modulation wire outlet hole and the pigtail outlet slot outlet (6) constitute an optical fiber and wire guiding system of the entire sensitive ring assembly, and are reasonably arranged to cooperate with each other so that each pigtail is independent of each other and optically isolated to avoid mutual interference.

In view of the influence of the optical fiber and the stress susceptibility, the tail fiber outlet (4) adopts a slope design, so that the tail fiber can smoothly enter the optical fiber receiving groove (2) after passing through the tail fiber outlet (4).

[0036] Among them, the fiber outlet of the screening fixed tooling after assembly leaves enough space for the optical fiber, effectively preventing the tooling from damaging the optical fiber, while ensuring that the internal structure of the fixed tooling is not exposed too much, so as to avoid the impact of the external environment on the optical fiber.

[0038] Example 1

[0039] This embodiment provides a sensitive ring assembly screening and fixing tool, such as Figure 1 The sensitive ring assembly is shown as the base of the screening fixture. The sensitive ring assembly is placed Figure 1 The sensitive ring assembly is fixed at the assembly fixing position 3 in the screening fixture base; the assembly pigtail is thrown out from the pigtail outlet 4, and the fiber coil is stored along the fiber storage groove 2 in the screening fixture base. The stored fiber passes through Figure 1 The sensitive ring assembly screening fixed tool base in the pigtail fiber outlet slot 1 leads out; the modulation wire on the sensitive ring assembly passes through Figure 1 The sensitive ring assembly is screened and connected to the modulation wire outlet hole 5 on the fixing tool base.

[0040] The utility model also includes a sensitive ring assembly screening fixed tooling protective cover, such as Figure 2 The protective cover of the screening fixture of the sensitive ring assembly includes a pigtail outlet slot 6, which matches the pigtail outlet slot 1 of the screening fixture base, and the pigtail test end of the sensitive ring assembly is led out from it.

[0041] In this solution, one sensitive ring component screening fixture can assemble 6 sensitive ring components at the same time. The previous fixtures can only assemble one or three sensitive ring components, but the fixtures are large in size and the number of sensitive components to be tested is small, which greatly wastes the test temperature chamber space; due to the extreme protection of sensitive ring components in this solution, the fixture designed to assemble more than 6 sensitive ring components cannot be operated by one person in actual operation. Therefore, this solution adopts the most reasonable state of installation of 6 sensitive ring components.

[0042] In this solution, except for the sensitive ring component pigtail test end and the modulation wire being led out, the rest of the parts are inside the sensitive ring component screening fixed tooling. Therefore, in the screening test, multiple tooling can be placed in the temperature box for simultaneous testing, which greatly improves the screening work efficiency. At the same time, the staff does not need to worry about damaging the fragile sensitive ring components during operation.

[0043] In order to reasonably protect the sensitive ring components, the fixed position of the sensitive ring components is lower than the surface of the sensitive ring screening fixture base, so the sensitive ring pigtail outlet position is lower than the optical fiber storage slot. Combined with the factors that affect the optical fiber and are susceptible to stress, the pigtail outlet adopts a slope design, such as Figure 3 (marked position in the figure), so that the pigtail passes through the pigtail outlet 4 and enters the optical fiber receiving groove 2 smoothly.

[0044] The fiber storage groove 2 is designed on the periphery of the sensitive ring component, which is consistent with the direction of the pigtail. The pigtail storage path is planned according to the position of each sensitive ring component. The fiber coil storage is completed along the fiber storage groove 2, which is convenient for distinguishing and managing each sensitive ring component. At the same time, the pigtail test ends of the 6 sensitive ring components are introduced into the pigtail outlet groove 1, which is neatly arranged and has the same fiber outlet direction.

[0045] The sensitive ring component fixing position 3, the optical fiber receiving groove 2, the pigtail outlet 4 and the pigtail outlet groove 1 are overall planned and reasonably arranged to cooperate with each other, so that each pigtail is independent of each other to avoid mutual interference, and the volume of the sensitive ring component screening fixed tooling is reduced as much as possible, which is convenient for operation and improves test efficiency.

[0046] During the screening process, the test equipment sends a modulated signal ladder wave to the sensitive ring assembly through the modulated wire on the sensitive ring assembly. The energized wires and optical fibers are placed in an interlaced manner in the same space, and the interference with the optical signal will directly affect the test accuracy of the sensitive ring assembly. In order to avoid the photoelectric interference between the modulated wire and the optical fiber, 6 corresponding through holes are opened from the fixed position 3 of the sensitive ring assembly to the edge of the tooling opposite to the center of the sensitive ring assembly as the modulated wire outlet holes. The modulated wire on the sensitive ring assembly is passed through to the outside of the screening fixed tooling, which not only avoids photoelectric interference, but also facilitates the positioning of the wire direction on the sensitive ring assembly. Figure 4 (Marked location in the picture).

[0047] The edge of the base of the sensitive ring component screening and fixing tooling is designed as a boss, and the protective cover of the sensitive ring component screening and fixing tooling is snapped onto the outside of the boss of the base, which is convenient for carrying the protective cover of the sensitive ring component screening and fixing tooling while effectively protecting the sensitive ring component to avoid the influence of external factors and possible misoperation by the operator during the experiment.

[0048] The protective cover of the sensitive ring component screening fixed tooling is provided with a pigtail outlet slot, which cooperates with the pigtail outlet slot of the tooling base. After assembly, the fiber outlet of the sensitive ring component screening fixed tooling leaves enough space for the optical fiber, effectively preventing the tooling from causing damage to the optical fiber, while ensuring that the internal structure of the fixed tooling is not exposed excessively, so as to avoid the influence of the external environment on the optical fiber.

[0049] All the edges and corners on the base and protective cover of the sensitive ring component screening fixture are rounded and polished, which not only protects the sensitive ring component pigtails and wires, but also ensures the safety of operators and ensures the stability and consistency of the sensitive ring component testing process.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
