Description

Technical Field

[0001] This utility model relates to the field of circulator testing technology, specifically a testing fixture for a wired circulator. Background Technology

[0002] Existing circulators are multi-port devices that transmit incident waves entering any of their ports to the next port in a sequential direction determined by a static bias magnetic field. As a non-reversible device with several ports, the circulator's significant feature is its ability to transmit high-frequency signal energy in one direction, thus making it well-suited for applications in isolators, duplexers, and reflective amplifiers.

[0003] Currently, in order to further optimize the production quality of circulators, researchers in related fields have developed test fixtures for circulators. However, based on the applicant's actual use, the existing test fixtures have relatively complex fitting and clamping structures for circulators and have significant limitations in versatility. Furthermore, the assembly and testing of the kit is constrained by the clearance space of the specific testing device, and the handling is also inconvenient. Therefore, in order to address the problems of the existing technology, the applicant will provide a test fixture for circulators with wires. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a testing fixture for a wired circulator, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a test fixture for a wire circulator, including a test support, a detection space is provided in the front end of the test support, and a buckle fixing device is installed on the rear end of the test support to clamp and press the detection space. Test connectors are fitted on both sides and the front end of the detection space, and microstrip wires are nested inside the test connectors.

[0006] Preferably, one end of the test connector extends to the outside of the test support, and the structural corners of the test support are all set with rounded corners to improve the comfort of use.

[0007] Preferably, the test support has a threaded hole on its rear end structure, and the bottom structure of the buckle fastener is installed with screws to the threaded hole, providing convenient conditions for subsequent maintenance and replacement.

[0008] Preferably, a support frame is installed at the bottom of the test support, and mounting grooves are provided in the bottom structure on both sides of the support frame, so as to provide stable installation conditions for the test support and related structures.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This utility model comprises a multifunctional testing fixture consisting of a test support, microstrip line, snap fastener, test connector, testing space, and support frame. It provides convenient clamping and limiting conditions during subsequent circulator testing, which helps improve the accuracy and stability of test results. Furthermore, the overall testing fixture has a simple structure and controllable manufacturing costs. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 A test fixture for a wired circulator includes a test support 1, a test space 5 is provided in the front end of the test support 1, and a buckle retainer 3 is installed on the rear end of the test support 1 to clamp and press the test space 5. Test connectors 4 are fitted on both sides and the front end of the test space 5, and microstrip wires 2 are nested inside the test connectors 4.

[0018] One end of the test connector 4 extends to the outside of the test support 1. The structural corners of the test support 1 are all rounded to improve the comfort of use. The rear end structure of the test support 1 is provided with a threaded hole. The bottom structure of the snap fastener 3 is installed with the threaded hole by screws, which provides convenient conditions for subsequent maintenance and replacement. The bottom of the test support 1 is equipped with a support frame 6. The bottom structure on both sides of the support frame 6 is provided with mounting grooves. The support frame 6 provides stable installation conditions for the test support 1 and related structures.

[0019] Working principle: In use, press the buckle retainer 3 to temporarily move the front end of the buckle retainer 3 away from the detection space 5. Then, install the circulator to be tested inside the detection space 5 and assemble it with the three test connectors 4 and the microstrip lines 2 inside the three test connectors 4. After completion, release the force restriction on the buckle retainer 3 so that the front end of the buckle retainer 3 clamps the circulator to be tested inside the detection space 5, ensuring the stability of the circulator to be tested in the subsequent testing process. After the subsequent testing is completed, press the buckle retainer 3 to temporarily move the front end of the buckle retainer 3 away from the detection space 5, and remove the tested circulator by the clamped edge.
