[0015] Furthermore, the clamping assembly includes a baffle, a connecting plate, a first elastic telescopic rod, a second elastic telescopic rod, and a clamping plate, wherein the connecting plate is fixed to the movable end of the universal joint.

[0016] Furthermore, the first elastic telescopic rod and the second elastic telescopic rod are respectively fixed on both sides of the connecting plate, the baffle is fixed at one end of the first elastic telescopic rod and the second elastic telescopic rod, and the clamp is fixed at the other end of the first elastic telescopic rod and the second elastic telescopic rod.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by pulling the clamp and the baffle apart in opposite directions and then placing the converter between the clamp and the baffle, the converter can be clamped in the baffle by the elastic preload of the first elastic telescopic rod and the second elastic telescopic rod.

[0018] Furthermore, the cross-section of the buried wire groove along the axial direction of the column is two-thirds circular.

[0019] Furthermore, the opening width of the buried wire groove is smaller than the diameter of the buried wire groove.

[0020] The beneficial effect of adopting the above-mentioned further solution is that it can effectively wrap the wire harness, and is suitable for wire harnesses with a diameter smaller than the diameter of the buried wire groove but larger than the opening width, so that it is stable when it is stuck in the buried wire groove, and thus is not easy to fall off.

[0021] Furthermore, the magnetic block is a rubidium magnet. Attached Figure Description

Detailed Implementation

[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0030] During audio and video signal conversion testing, the test equipment usually needs to connect multiple wire harnesses to achieve signal transmission and conversion. However, during the test, due to the lack of effective wire harness management, the wire harnesses are prone to tangling, crossing, or loosening, which not only makes the test environment messy and unstandardized, but also affects the test efficiency. In response, the inventor of this utility model proposes a portable multi-terminal audio and video signal intelligent conversion test rack to solve the above problems.

[0031] The present invention provides the following preferred embodiments.

[0033] Support level 10;

[0034] The column 60 has one end fixed to the top of the support plate 10 in the center;

[0035] Universal joint 20, universal joint 20 is installed on the top of column 60;

[0036] Clamping assembly 30 is disposed on the movable end of universal joint 20;

[0037] Multiple sets of cable routing clips 40 are respectively installed on the outside of the column 60. Each set of cable routing clips 40 includes a bushing 401, a support plate 402, a clamping plate 403, a slot 404, a magnetic metal 405 (the magnetic metal 405 is made of iron), and a magnetic block 406. The bushing 401 is rotatably connected to the outside of the column 60 via a rotating shaft. The support plate 402 is fixed to the outside of the bushing 401. The clamping plate 403 is rotatably connected to one side of the support plate 402 via a rotating shaft. The slot 404 is opened between the support plate 402 and the clamping plate 403. The magnetic metal 405 is fixed on the side of the support plate 402 and the clamping plate 403 facing each other. The magnetic block 406 is fixed on the side of the clamping plate 403 and the support plate 402 facing each other.

[0038] The audio / video converter is securely fixed to the column 60 by the clamping component 30. Multiple sets of cable routing clips 40 are also installed on the outside of the column 60, allowing multiple cable harnesses connected to the converter to pass through the clips 404. The rotation function of the bushing 401 outside the column 60 enables flexible adjustment of the multiple cable harnesses in various directions, effectively preventing tangling and crossing between cable harnesses, resulting in a cleaner and more standardized testing environment. Furthermore, the clamping plate 403 is rotatably connected to the support plate 402 via a pivot, and combined with the magnetic fixing mechanism of the magnetic block 406 and the magnetic metal 405, it not only facilitates the quick insertion and removal of cable harnesses but also ensures stable positioning of the cable harnesses within the clips 404, preventing accidental detachment. In summary, the cable harness organization structure of this test fixture optimizes the standardization of the testing process, is suitable for various audio / video conversion testing scenarios, and has high practical value and promising prospects for promotion.

[0039] In this embodiment, as Figures 1-5 As shown, the top of the support plate 10 has a spiral-shaped wire trough 50, which can effectively store excess wires, allowing them to be wound in an orderly manner and buried in the trough, preventing the wires from being scattered or hanging, and ensuring the cleanliness and standardization of the testing environment.

[0040] In this embodiment, as Figures 1-5 As shown, the clamping assembly 30 includes a baffle 301, a connecting plate 302, a first elastic telescopic rod 303, a second elastic telescopic rod 304, and a clamping plate 305. The connecting plate 302 is fixed to the movable end of the universal joint 20. The first elastic telescopic rod 303 and the second elastic telescopic rod 304 are respectively fixed to both sides of the connecting plate 302. The baffle 301 is fixed to one end of the first elastic telescopic rod 303 and the second elastic telescopic rod 304. The clamping plate 305 is fixed to the other end of the first elastic telescopic rod 303 and the second elastic telescopic rod 304.

[0041] Pull the clamp 305 and the baffle 301 apart in opposite directions, and then place the converter between the clamp 305 and the baffle 301. The converter can be clamped in the baffle by the elastic preload of the first elastic telescopic rod 303 and the second elastic telescopic rod 304.

[0042] In this embodiment, as Figures 1-5 As shown, the cross-section of the buried wire groove 50 along the axial direction of the column 60 is two-thirds of a circle. The opening width of the buried wire groove 50 is smaller than the diameter of the buried wire groove 50, which can effectively wrap the wire harness. It is suitable for wire harnesses with a diameter smaller than the diameter of the buried wire groove 50 but larger than the opening width, so that the wire harness is stable after being inserted into the buried wire groove 50 and is not easy to fall off.

[0043] In this embodiment, as Figures 1-5 As shown, the magnetic block 406 uses a rubidium magnet.

[0044] The specific working process of this utility model is as follows:

[0045] (1) Limit the audio / video converter

[0046] First, pull the clamping plate 305 and the baffle 301 apart in opposite directions, and then place the converter between the clamping plate 305 and the baffle 301. The converter can be clamped in the space by utilizing the elastic pre-tightening force of the first elastic telescopic rod 303 and the second elastic telescopic rod 304.

[0047] (2) Organize the test harness

[0048] Multiple cable harnesses connected to the audio / video converter (Ultra-High Definition Video Scalar HDMI to HDMI Digital Scalar Converter Model: YT-HD1601) can pass through the bayonet 404 respectively. Through the rotation function of the bushing 401 outside the column 60, multiple cable harnesses can be flexibly adjusted in various directions, thereby effectively avoiding tangling and crossing between cable harnesses and making the testing environment cleaner and more standardized. In addition, the card plate 403 is rotatably connected to the carrier plate 402 through the rotating shaft. Combined with the magnetic fixing mechanism of the magnetic block 406 and the magnetic metal 405, it is convenient for the cable harness to be quickly inserted and removed.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
