Description

Technical Field

[0001] This utility model relates to the field of TR fixtures, and in particular to a TR component fixture. Background Technology

[0002] In the testing of TR components, high requirements are placed on the positioning accuracy, operational stability, signal transmission consistency, and assembly / disassembly efficiency of the fixtures. However, existing fixtures used for TR component testing often have several problems: Firstly, the docking of TR components with testing equipment often relies on manual adjustment, lacking a precise positioning structure, which can easily lead to inaccurate interface docking due to positioning deviations, resulting in testing errors. Secondly, the stability of the moving components is insufficient, making them prone to shaking during docking, affecting the reliability of the connection. Moreover, the assembly / disassembly process is complex, requiring cumbersome wiring operations, which significantly reduces testing efficiency. At the same time, the signal transmission components lack effective protective structures, making them susceptible to interference from external dust, collisions, etc., resulting in poor signal transmission consistency and affecting the stability of test data. In addition, some fixtures have unreasonable structural designs, which can easily cause interference between components, limiting the operating space and increasing the risk of interface damage. These problems collectively restrict the stability and efficiency of TR component testing. Utility Model Content

[0003] The purpose of this invention is to provide a TR component fixture that solves the above-mentioned problems.

[0004] This utility model is achieved through the following technical solution: A TR component fixture includes a base plate and side supports on both sides of the base plate. The length of the side supports is less than the length installed on the edge of the base. Two slide rails parallel to the side supports are installed on the surface of the base plate between the lower support portions of the two side supports and in the blank area at the edge of the base plate. Sliders that can slide freely are provided on the two slide rails. A push assembly parallel to the slide rails is provided in the middle of the base plate between the two slide rails. A test control panel is installed on the upper surface of the push assembly. The lower surface of the test control panel is also fixedly connected to the two sliders. The support is divided into a high support portion and a low support portion. The high support portion is close to the test control panel and corresponds to the lower end of the test control panel. A placement plate is provided on the high support portion between the two side supports. An RF connection assembly for the placement plate is provided on the low support portion between the two side supports.

[0005] Furthermore, The pushing assembly includes a lead screw support, a lead screw fixing seat, a lead screw, a nut seat, and a rotating handwheel. The lead screw support is installed in the middle of the base plate between the two slide rails. A lead screw fixing seat is set on the base plate below the lead screw support in the direction parallel to the slide rails. A lead screw that can rotate around its own axis is set between the lead screw fixing seat and the lead screw support. The lead screw is parallel to the slide rails and passes through the lead screw support and is fixedly connected to the rotating handwheel. A nut seat is suspended on the lead screw between the lead screw support and the lead screw fixing seat. The test control panel is fixedly and vertically connected to the nut seat.

[0006] Furthermore, The RF connection assembly includes a mounting plate, a PCB board, RF connectors, and a cover. The mounting plate is positioned on a low support between two side brackets. A PCB board with a protruding portion is mounted on the upper surface of the mounting plate. RF connectors are evenly arranged on the edges of the PCB board that are opposite to and in the direction of the test control panel. The cover is an integral piece that can cover the sides, top, and sides of the PCB board where the RF connectors are mounted. The cover has a hole at one end corresponding to the RF connector for the RF connector to pass through and is fixedly connected to the side brackets on both sides.

[0007] Furthermore, The placement board is aligned with one end of the high support near the test control panel, and the other end extends beyond the width of the high support and is opposite to the protruding part of the PCB board. Holes are made at the protruding part of the PCB board corresponding to the placement board, and limit posts are vertically installed at one corner of the test control panel.

[0008] Furthermore, The PCB board has a protruding part with a plug-in interface that can be connected to the TR component.

[0009] Furthermore, The distance between the cover and the base plate is greater than the distance between the placement plate and the base plate.

[0010] The next step, A locking handle is also installed on the upper surface of the lead screw support.

[0011] The beneficial effects of this utility model are: 1. The push component drives the lead screw to rotate by rotating the handwheel, which in turn drives the nut seat to move smoothly along the lead screw axis. This, in turn, drives the test control panel to slide synchronously along the slide rail via the slider, achieving precise adjustment of the test control panel's position. This ensures the stability of the movement process, facilitates precise docking with the TR component, and effectively improves the controllability of operation and docking accuracy.

[0012] 2. The protruding portion of the placement board and the holes provided a spatial channel for the mating of the TR component and the protruding part of the PCB board, facilitating the connection of the TR component's plug-in interface through the holes to the PCB board. The diagonally positioned limiting posts on the test control panel accurately position the TR component, preventing displacement during operation and ensuring accurate mating, reducing test errors caused by positioning deviations. The plug-in interfaces on the protruding part of the PCB board enable quick connection and disconnection of the TR component from the PCB board, eliminating the need for complex wiring operations, significantly simplifying the TR component assembly and disassembly process, and improving test efficiency. Simultaneously, standardized plug-in interfaces ensure connection consistency, reducing signal transmission problems caused by improper connections and enhancing test stability.

[0013] 3. The height of the cover from the base plate is higher than the height of the placement board from the base plate. During the docking process, the part of the cover that is higher than the placement board can act as a barrier to prevent the TR component from moving due to the plugging of the test control panel, thus protecting the plug-in interfaces on the PCB board.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0019] See Figures 1 to 3 : A TR component fixture includes a base plate 1 and side supports 6 disposed on both sides of the base plate 1. The length of the side supports 6 is less than the length installed on the edge of the base. Two slide rails 2 parallel to the side supports 6 are installed on the surface of the base plate 1 between the lower support portions of the two side supports 6. Sliding sliders 3 that can slide freely are disposed on the two slide rails 2. A pushing component 4 parallel to the slide rails 2 is disposed in the middle of the base plate 1 between the two slide rails 2. A test control panel 5 is disposed on the upper surface of the pushing component 4. The lower surface of the test control panel 5 is also fixedly connected to the two sliders 3. The support is divided into a high support portion and a low support portion. The high support portion is close to the test control panel 5 and corresponds to the lower end of the test control panel 5. A placement plate 7 is disposed on the high support portion between the two side supports 6. An RF connection component 8 of the placement plate 7 is disposed on the low support portion between the two side supports.

[0020] Furthermore, The pushing assembly 4 includes a lead screw support 40, a lead screw fixing seat 41, a lead screw 42, a nut seat 43, and a rotating handwheel 44. The lead screw support 40 is installed in the middle of the base plate 1 between the two slide rails 2. In the direction parallel to the slide rails 2, a lead screw fixing seat 41 is set on the base plate 1 below the placement plate 7. A lead screw 42 that can rotate around its own axis is set between the lead screw fixing seat 41 and the lead screw support 40. The lead screw 42 is parallel to the slide rails 2 and passes through the lead screw support 40 and is fixedly connected to the rotating handwheel 44. A nut seat 43 is suspended on the lead screw 42 between the lead screw support 40 and the lead screw fixing seat 41. The test control panel 5 is fixedly and vertically connected to the nut seat 43.

[0021] Rotating the handwheel 44 drives the lead screw 42 to rotate, which in turn drives the nut seat 43 to move smoothly along the axis of the lead screw 42. This, in turn, drives the test control panel 5 to slide synchronously along the slide rail 2 via the slider 3, thereby achieving precise adjustment of the position of the test control panel 5. This ensures the stability of the movement process, facilitates precise docking of the test control panel 5 with the TR component, and improves the controllability of the operation and the docking accuracy.

[0022] Furthermore, The RF connection assembly 8 includes a mounting plate 80, a PCB board 81, an RF connector 82, and a cover 83. The mounting plate 80 is mounted on a low support between the two side brackets 6. The PCB board 81 with a protruding part 810 is mounted on the upper surface of the mounting plate 80. The RF connectors 82 are evenly arranged on the edge of the PCB board 81 that is opposite to the direction of the test control panel 5. The cover 83 is an integral piece that can cover the two sides, the top, and the side where the RF connectors 82 are mounted on the PCB board 81. The cover 83 has a hole 71 at one end corresponding to the RF connector 82 for the RF connector 82 to pass through and is fixedly connected to the side brackets 6 on both sides.

[0023] The evenly distributed RF connectors 82 ensure the consistency of signal connection and improve the stability of test data; the integrated cover 83 can effectively protect the PCB board 81 and RF connectors 82 from external dust, collisions and other interference, while not affecting the normal connection of RF connectors 82; the fixation of the cover 83 and the side bracket 6 enhances the stability of the overall structure and further ensures the reliability of RF signal transmission.

[0024] Furthermore, The placement plate 7 is aligned with one end of the high support near the test control panel 5, and the other end extends beyond the width of the high support and is opposite to the protrusion 810 of the PCB board 81. A hole 71 is opened on the placement plate 7 at the protrusion 810 of the PCB board 81, and a limiting post 70 is vertically installed at one of the corners of the test control panel 5.

[0025] The extended portion of the placement plate 7 and the hole 71 provide a space channel for the mating of the TR component and the protruding portion 810 of the PCB board 81, facilitating the connection of the TR component's plug-in interface 811 through the hole 71 to the PCB board 81; the diagonally arranged limiting posts 70 can accurately position the TR component placed on the test control panel 5, preventing it from shifting during operation, ensuring the accuracy of the mating position, and reducing test errors caused by positioning deviations.

[0026] Furthermore, The PCB board 81 has a protruding portion 810 with a plug-in interface 811 that can be connected to the TR component.

[0027] The plug-in interface 811 enables quick connection and disconnection of the TR component and the PCB board 81 without complicated wiring operations, greatly simplifying the assembly and disassembly process of the TR component and improving testing efficiency. At the same time, the standardized plug-in interface 811 can ensure the consistency of the connection, reduce signal transmission problems caused by improper connection, and enhance the stability of the test.

[0028] Furthermore, The height of the cover 83 from the base plate 1 is greater than the distance of the placement plate 7 from the base plate 1.

[0029] The height difference between the cover 83 and the placement plate 7 avoids structural interference between the cover 83 and the TR component on the placement plate 7, providing ample space for the placement, docking, and testing of the TR component, reducing the risk of collisions between components, ensuring both safe operation of the equipment and smooth operation. Simultaneously, when the test control panel 5 is plugged into and docked with the TR component, the TR component is aligned and connected to the plug-in interface 811 on the PCB protrusion 810 via the limiting post 70, thus aligning the TR component with the test control panel 5. During the process of moving the test control panel 5 towards the TR component by pushing component 4, the portion of the cover 83 that protrudes above the placement plate 7 acts as a blocking block, preventing the TR component from moving due to the insertion of the test control panel 5 and damaging the plug-in interface 811 on the PCB 81.

[0030] The next step, A locking handle 401 is also installed on the upper surface of the lead screw support 40.

[0031] In one embodiment, the lead screw support 40 adopts the BK-15 model, and the lead screw 42 is locked and fixed by rotating the locking handle 401 to prevent accidental contact after docking.

[0032] The method of using this utility model is as follows: In use, the TR component is first placed on the test control panel 5. The limiting post 70 at the opposite corner can accurately position the TR component to prevent displacement during operation. Then, by rotating the rotating handwheel 44 of the push component 4, the lead screw 42 is driven to rotate around its own axis, causing the nut seat 43 sleeved on the lead screw 42 to move axially. This, in turn, drives the test control panel 5 to slide synchronously along the slide rail 2 via the slider 3. This process utilizes the stability of the lead screw 42 transmission to achieve precise adjustment of the position of the test control panel 5, ensuring smooth movement and guaranteeing docking accuracy.

[0033] When the test control panel 5 is moved to the appropriate position, the TR component placed on it will move along with it. The portion of the placement plate 7 that extends beyond the high support and the corresponding holes 71 on the protruding portion 810 of the PCB board 81 provide a channel for the TR component to connect with the PCB board 81. This allows the TR component's plug-in interface 811 to pass through the holes 71 and connect precisely with the interface on the protruding portion 810 of the PCB board 81. At the same time, the RF connectors 82, which are evenly spaced along the edge of the PCB board 81, can connect to external devices through the holes 71 of the cover 83. Their even spacing design ensures consistent signal connection, while the integrated cover 83 can shield the sides and top of the PCB board 81 and the sides of the RF connectors 82, effectively protecting the components from external interference. Furthermore, the cover 83 is higher than the placement plate 7, avoiding structural interference with the TR component. After docking is completed, the locking handle 401 on the lead screw support 40 can fix the position of the lead screw 42 to prevent accidental displacement, ultimately achieving stable testing of the TR component.

[0034] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
