Description

Technical Field

[0001] This utility model relates to the technical field of power dividers, and specifically to a rapid testing fixture for power dividers. Background Technology

[0002] A power divider, or simply power splitter, is a device that splits the energy of a single signal into two or more outputs of equal or unequal energy, or vice versa, combines the energy of multiple signals into a single output. Power dividers are widely used in various electronic systems such as microwave communication, radar, electronic countermeasures, and microwave measurement.

[0003] The main specifications of a power divider include voltage standing wave ratio (VSWR), insertion loss, and isolation. Power dividers typically use non-standard interfaces, making it impossible to directly connect them to testing equipment for their electrical performance parameters. Therefore, specialized test fixtures must be designed for testing.

[0004] However, in existing power divider testing, the ports of the power divider are distributed at the front and rear ends or left and right ends of the machine body, and their positions are not on the same plane. Therefore, vertical clamping is required when clamping them. When clamping the large upper and lower surfaces of the machine body, traditional clamps are difficult to ensure the uniformity of clamping at various angles of the machine body, and the clamping stability needs to be improved. In addition, when testing multiple ports, it is not convenient and quick to rotate and adjust the machine body, and the ease of operation needs to be improved.

[0005] Therefore, this utility model proposes a rapid testing fixture for power dividers. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a rapid testing fixture for power dividers, which can solve the following problems:

[0007] When testing existing power dividers, the ports of the power divider are distributed at the front and rear ends or left and right ends of the longitudinal direction of the machine body, and their positions are not on the same plane. Therefore, they need to be clamped vertically. However, when traditional clamps clamp the large upper and lower surfaces of the machine body, it is difficult to ensure the uniformity of clamping at all angles of the machine body, and the clamping stability needs to be improved.

[0008] When testing multiple ports, the machine body cannot be rotated and adjusted quickly and easily, and the ease of operation needs to be improved.

[0009] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0010] A power divider rapid testing fixture includes a base plate, with a first connecting plate, a second connecting plate and a third connecting plate fixedly connected to both ends of the base plate respectively. A fixing frame is fixedly connected to the surface of the first connecting plate, and a testing mechanism is fixedly connected to the inner end of the fixing frame. A guide platform is fixedly connected to the surface of the base plate, and a support assembly is movably connected to the surface of the guide platform. A connecting frame is movably arranged above the support assembly, and a support plate is fixedly connected to the inner end of the connecting frame.

[0011] The support assembly includes a support platform and a limiting platform that are fixedly connected. The bottom end of the support platform is fixedly connected to a guide foot. A guide rod is provided through the inner end of the connecting frame. The bottom end of the guide rod is provided with an inner limiting plate and an outer limiting support plate that are fixedly connected. The bottom end of the support platform is fixedly connected to a lower connecting plate.

[0012] Furthermore, the guide platform is arranged in an "L" shape, with transverse guide grooves on both sides of the surface corresponding to the support components, and the third connecting plate is arranged in an "L" shape and is located at the outer end of the guide platform.

[0013] Furthermore, the vertical angle end of the guide platform has a through-hole corresponding to the connecting frame, and the through-holes are distributed longitudinally.

[0014] Furthermore, the connecting frame is rectangular in shape, with its outer end movably passing through the guide platform and its inner end inclined at a downward angle. The support plate is horizontally connected above the inclined section of the inner end of the connecting frame, and a lifting drive mechanism that is also connected to the guide rod is fixedly connected to the surface of the support plate.

[0015] Furthermore, both the support platform and the limiting platform are rectangular platforms distributed vertically, with the guide feet located at the bottom corner of the support platform, which simultaneously slide into the transverse guide groove on the surface of the guide platform.

[0016] Furthermore, the lower connecting plate protrudes in an "L" shape, and an electric telescopic rod is fixedly connected between it and the third connecting plate.

[0017] Furthermore, the guide rod is vertically movable through the inner end of the connecting frame, the inner limiting plate is a rubber suction cup, and four sets of outer limiting support plates are equidistantly distributed along the outer side of the inner limiting plate. The outer limiting support plates are inclined downwards and have rubber pads on their bottom surfaces.

[0018] Furthermore, the inner limit plate and guide rod are movably connected.

[0019] As can be seen from the above technical solution, the beneficial effects of this utility model are:

[0020] 1. This utility model achieves the effect of facilitating the sliding adjustment of the support component along the guide groove on its surface through the guide table, and at the same time, the through opening at the vertical angle end of the guide table facilitates the sliding adjustment of the connecting frame.

This utility model achieves the effect of facilitating the movement and adjustment of the inner limit plate and the outer limit support plate according to the position of the support component through the sliding connecting frame, and achieves the effect of facilitating the installation and support of the lifting drive mechanism through the support plate.

A fixing frame 6 is fixedly connected to the surface of the first connecting plate 3. A testing mechanism 5 is fixedly connected to the inner end of the fixing frame 6. A guide platform 7 is fixedly connected to the surface of the base plate 1. A support assembly 9 is movably connected to the surface of the guide platform 7. A connecting frame 10 is movably arranged above the support assembly 9. A support plate 2 is fixedly connected to the inner end of the connecting frame 10. The support assembly 9 includes a support platform 12 and a limiting platform 13 fixedly connected. A guide foot 14 is fixedly connected to the bottom end of the support platform 12. A guide rod 16 is passed through the inner end of the connecting frame 10. An inner limiting plate 17 and an outer limiting support plate 15 are fixedly connected to the bottom end of the guide rod 16. A lower connecting plate 11 is fixedly connected to the bottom end of the support platform 12.

[0032] In this embodiment of the utility model, the guide platform 7 is generally L-shaped, and the two sides of the surface are provided with transverse guide grooves corresponding to the support components 9. The third connecting plate 8 is L-shaped and protrudes, located at the outer end of the guide platform 7. The vertical corner end of the guide platform 7 is provided with a through-hole corresponding to the connecting frame 10. The through-holes are distributed longitudinally. The guide platform 7 facilitates the sliding adjustment of the support components 9 along the guide grooves on its surface. At the same time, the through-holes at the vertical corner end of the guide platform 7 facilitate the sliding adjustment of the connecting frame 10.

[0033] The connecting frame 10 is generally rectangular, with its outer end movably passing through the guide platform 7 and its inner end inclined downwards at a bend. The support plate 2 is horizontally connected above the inclined section of the inner end of the connecting frame 10. The surface of the support plate 2 is fixedly connected to a lifting drive mechanism that is also connected to the guide rod 16. The sliding connecting frame 10 facilitates the movement and adjustment of the inner limit plate 17 and the outer limit support plate 15 according to the position of the support component 9. The support plate 2 facilitates the installation and support of the lifting drive mechanism.

[0034] The support platform 12 and the limiting platform 13 are both rectangular platforms distributed vertically. The guide foot 14 is located at the bottom corner of the support platform 12 and is simultaneously slidably embedded in the transverse guide groove on the surface of the guide platform 7. The lower connecting plate 11 is L-shaped and protrudes. An electric telescopic rod is fixedly connected between it and the third connecting plate 8. The support platform 12 and the limiting platform 13 achieve the effect of supporting and placing the power divider. The lower connecting plate 11, in conjunction with the electric telescopic rod, facilitates the movable connection between the support assembly 9 and the third connecting plate 8.

[0035] The guide rod 16 is vertically and movably installed through the inner end of the connecting frame 10. The inner limiting plate 17 is a rubber suction cup.

The guide rod 16 facilitates the height adjustment of the inner limiting plate 17 and the outer limiting support plate 15. The outer limiting support plate 15 and the inner limiting plate 17 achieve the effect of pressing down and fixing the power divider body from above. At the same time, the movable inner limiting plate 17 is easy to rotate and adjust.

[0036] When testing the power divider, it is placed horizontally on the limiting platform 13. Then, the electric telescopic rod between the lower connecting plate 11 and the third connecting plate 8 controls the support assembly 9 to slide and adjust along the surface of the guide platform 7 to ensure the rotation space of the power divider. Then, the position of the connecting frame 10 is manually adjusted so that the inner limiting plate 17 and the outer limiting support plate 15 are located above the machine body. Then, the lifting drive mechanism connected to the guide rod 16 is activated, controlling the guide rod 16 to descend, so that the inner limiting plate 17 and the outer limiting support plate 15 are pressed down and fixed from above the machine body. Then, the detection mechanism 5 on the side detects the ports of the power divider. When the detection position needs to be adjusted, the operator can rotate the power divider to adjust the detection position of different ports.
