[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0018] according to Figure 1-Figure 4 As shown, this embodiment proposes a double-shielding test fixture for a sensitive ring assembly, including a base 1, a first sealing cover 2, a placement seat 3, a second sealing cover 4, a fixing assembly, a first assembly assembly and a second assembly assembly. A placement seat 3 for placing the sensitive ring assembly is installed above the base 1 through a fixing assembly, a first sealing cover 2 is installed on the top of the base 1 through a first assembly assembly, a second sealing cover 4 is installed on the top of the placement seat 3 through a second assembly assembly, and the second sealing cover 4 is located in the first sealing cover 2. A fiber optic lead-out platform 5 is provided on one side of the base 1, and six fiber outlet grooves 6 are provided on the fiber optic lead-out platform 5. A pigtail outlet 7 is provided on the side of the placement seat 3 close to the fiber optic lead-out platform 5, and a notch 8 is provided on the side of the first sealing cover 2 close to the fiber outlet groove 6.

[0019] Fix the base 1 on the test platform of the temperature chamber, place the sensitive ring assembly in the placement seat 3, and after storing the pigtail and wires of the sensitive ring assembly, cover the placement seat 3 with the second sealing cover 4, and finally cover the base 1 with the first sealing cover 2 to complete the assembly. After that, the temperature chamber is sealed and the test data of the sensitive ring assembly can be collected. When the tested sensitive ring assembly needs to be replaced, it is only necessary to open the first sealing cover 2 and the second sealing cover 4 respectively, and then put the new sensitive ring assembly back in, repeat the above assembly steps, and a new round of sensitive ring assembly testing can be carried out. In this process, there is no need to replace new test tooling, which reduces production preparation time and further improves test efficiency. The first sealing cover 2 cooperates with the base 1, and the second sealing cover 4 cooperates with the placement seat 3. This double-layer shielding method reduces the influence of external factors on the sensitive ring assembly during the test.

[0020] A wire lead-out groove 9 is formed around the top edge of the base 1 , a wire outlet 10 is formed on one side of the pigtail outlet 7 on the placement seat 3 , and wire openings 11 are symmetrically formed on both sides of the groove 8 on the first sealing cover 2 .

[0021] Through the mutual cooperation of the optical fiber lead-out platform 5, the fiber outlet groove 6, the notch 8, the pigtail outlet 7, the wire lead-out groove 9, the wire outlet 10 and the wire opening 11, the optical fibers and wires of the sensitive ring assembly are classified and led out, the distribution and direction of the optical fibers and wires are reasonably arranged, the optical fibers and wires of the sensitive ring assembly are protected, and the reliability, stability and consistency of the sensitive ring assembly during the test are guaranteed.

[0022] The fixing assembly includes threaded holes 12. Four groups of threaded holes 12 are distributed in a rectangular shape on the base 1. A conical countersunk hole 13 is provided at the center of the placement seat 3. The placement seat 3 is fixed by screws fitting the threaded holes 12 and the conical countersunk hole 13.

[0023] This device fixes the placement seat 3 on the base 1 through the threaded hole 12 and the tapered countersunk hole 13 to ensure the stability of the placement seat.

[0024] The first assembly component includes a first sealing groove 14 . The first sealing groove 14 is provided on the outer side of the wire lead-out groove 9 , and the bottom of the first sealing cover 2 is embedded in the first sealing groove 14 .

[0025] The first sealing is formed between the first sealing groove 14 and the first sealing cover 2 , thereby reducing the influence of the outside world on the sensitive ring. At the same time, it is also more convenient to separate the first sealing cover 2 from the first sealing groove 14 .

[0026] The base 1 is further provided with cylindrical countersunk holes 15 at the four corners. The base 1 is fixed to the temperature chamber test platform through the cylindrical countersunk holes 15 and countersunk bolts.

[0027] The second assembly component includes a ridge 16 and a groove 17. The top of the placement seat 3 is provided with a ridge 16, and the bottom of the second sealing cover 4 is provided with a groove 17 adapted to the ridge 16. The second sealing cover 4 and the placement seat 3 are engaged by the engagement of the ridge 16 and the ridge groove, which facilitates separation.

[0028] The double-shielded test fixture for the sensitive ring component is constructed by placing the base 1 in the center on the test platform of the test incubator, passing the optical fiber lead-out platform 5 through the incubator hole, and fixing the base 1 on the test platform with screws through the cylindrical countersunk holes 15. The sensitive ring component to be tested is placed in the placement seat 3 avoiding the tapered countersunk hole 13, and the pigtail is coiled along the inner wall of the placement seat 3. The pigtail is put into a protective sleeve and led out from the pigtail outlet 7. The wire is led out from the wire outlet 10 avoiding the optical fiber, and high-temperature tape is used to fix the pigtail and the wire. The placement seat 3 equipped with the sensitive ring component is placed on the base 1 to ensure that the pigtail lead-out direction is consistent with the incubator hole. The directions are consistent, and the tapered countersunk hole 13 and the threaded hole 12 are connected with screws to complete the fixation of the placement seat 3. Then the second sealing cover 4 is engaged with the placement seat 3 to complete the first layer of shielding for the sensitive ring component test. The pigtail with the protective sleeve is led out of the temperature box through the slot 8, and the wire is led out of the temperature box through the wire opening 11. At the same time, the pigtail and the wire are fixed with high-temperature tape. After the pigtail and the wire are successfully connected to the test system, the first sealing cover 2 is engaged with the base 1 to complete the second layer of shielding for the sensitive ring component test. After the assembly is completed, the temperature box is sealed and the test data of the sensitive ring component can be collected.
