Description

Technical Field

[0001] This utility model relates to the field of three-port waveguide ferrite sheet installation technology, specifically to an installation and positioning fixture for a three-port waveguide ferrite sheet. Background Technology

[0002] During the installation of three-port waveguide ferrite sheets, workers need to accurately control the position of the ferrite sheets on the three-port waveguide. Currently, workers usually determine the position of the ferrite sheets by measuring with vernier calipers. However, this method has a certain measurement error and cannot guarantee the consistency of the ferrite sheet installation position, affecting the production quality of the three-port waveguide. In addition, workers cannot mark the installation position of the ferrite sheets, which requires workers to hold the vernier calipers in one hand to measure the position and install the ferrite sheets in the other hand, reducing the efficiency of ferrite sheet installation. Based on this, this application proposes an installation and positioning fixture for three-port waveguide ferrite sheets. Utility Model Content

[0003] This invention provides a mounting and positioning fixture for a three-port waveguide ferrite sheet, which solves the problem in the background art where determining the position of the ferrite sheet on the three-port waveguide using vernier calipers is inefficient and cannot guarantee product consistency.

The four sidewalls of the block body include an outer sidewall one adapted to the inner wall of the three-port waveguide, an outer sidewall two adapted to the inner wall of the three-port waveguide, a positioning sidewall one, and a symmetrical sidewall. The outer sidewall one and the outer sidewall two are arranged opposite to each other on the block body. The positioning sidewall one and the symmetrical sidewall one are arranged opposite to each other on the block body. The bottom end of the outer sidewall two is provided with a groove.

[0006] Preferably, the positioning sidewall is a vertical plane.

[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] See Figures 1 to 4 This utility model provides a mounting and positioning fixture for a three-port waveguide ferrite sheet, including a block-shaped body 1. The shape of the block-shaped body 1 is consistent with the shape of the inner cavity of the three-port waveguide. The block-shaped body 1 is provided with a fixing groove adapted to the inner step of the three-port waveguide. In use, the block-shaped body 1 can be installed inside the inner cavity of the three-port waveguide. Figure 1 and Figure 2As shown, the bottom of the block body 1 is adapted to the bottom of the three-port waveguide cavity. The four sidewalls of the block body 1 include an outer sidewall 5 adapted to the inner wall of the three-port waveguide, an outer sidewall 6 adapted to the inner wall of the three-port waveguide, a positioning sidewall 3, and a symmetrical sidewall 8. The outer sidewall 5 and the outer sidewall 6 are arranged opposite to each other on the block body 1, and the positioning sidewall 3 and the symmetrical sidewall 8 are arranged opposite to each other on the block body 1. The positioning sidewall 3 is a vertical plane. When the block body 1 is installed in the three-port waveguide cavity, the vertical plane where the positioning sidewall 3 is located overlaps with the installation position of the ferrite sheet, so that the ferrite sheet can be closely attached to the positioning sidewall 3 during installation. This positioning fixture realizes the positioning of the ferrite sheet.

[0018] The thickness of the block body 1 is greater than the height of the ferrite sheet, which facilitates the positioning fixture in positioning the ferrite sheet. The thickness of the block body 1 can be set according to requirements and is not limited here.

[0019] In addition, to facilitate the installation of the block body 1, this application provides a groove 4 at the bottom end of the outer side wall 2 6, such as Figure 3 and Figure 4 As shown, at this time, the size of the bottom of the block body 1 is smaller than the size of the three-port waveguide cavity. During the installation process, the staff can put the bottom of the block body 1 into the top of the three-port waveguide cavity, and then move the block body 1. The block body 1 is positioned by using the side wall of the three-port waveguide until the outer side wall 5 and the matching inner wall of the three-port waveguide fit together, which improves the convenience of installing the block body 1.

[0020] The aforementioned fixing groove includes a limiting groove 2 and a horn groove 7. The bottom of the horn groove 7 and the limiting groove 2 are smoothly transitioned. The limiting groove 2 is adapted to the inner step of the three-port waveguide. The width of the horn groove 7 gradually increases from top to bottom. The setting of the horn groove facilitates the movement of the block body 1 at the top of the inner cavity of the three-port waveguide.

[0021] In summary, when using this installation and positioning fixture, the operator snaps it into place with the three-port waveguide 9. Figure 1 and Figure 2 As shown, when installing the ferrite sheet 10, the worker tightly fits one end of the ferrite sheet 10 with the positioning fixture. The positioning fixture is used to position the ferrite sheet 10, which helps to improve the accuracy of installation and the consistency of product position. After the ferrite sheet 10 is installed, the worker removes the positioning fixture, which can be reused.
