[0002] The core purpose of testing DTU (Data Transmission Unit) and FTU (Feeder Terminal Unit) is to ensure the reliability of equipment functions, system stability, and safety of application scenarios. Currently, the functional and performance testing of distribution network automation FTUs or DTUs in the domestic market requires multiple instruments (multimeter, oscilloscope, DC power supply tester, etc.), and the testing process requires manual wiring, which is cumbersome.

[0003] Currently, when testing DTUs or FTUs, DTU / FTU testing fixtures are typically used to facilitate wiring operations. For example, an automated DTU / FTU testing fixture disclosed in patent CN209640418U solves the problems of existing manual wiring testing, high labor intensity for workers, and low testing efficiency and automation. However, in actual use, the docking mechanism adapter plate cannot be arbitrarily rotated to adjust the orientation of the aircraft plug female, thus affecting the ease of connection between the wiring harness on the DTU or FTU and the aircraft plug female, resulting in poor applicability of the testing fixture. Utility Model Content

[0004] The purpose of this invention is to provide a DTU and FTU testing docking fixture to solve the problems mentioned in the background art.

[0031] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0032] The following is in conjunction with the appendix Figures 1-5 This embodiment will be described in further detail.

[0033] like Figure 1 and Figure 2 As shown, a DTU / FTU testing docking fixture in this embodiment includes a base 100. The upper side of the base 100 forms a bearing surface for placing a DTU or FTU. Specifically, in order to enable the bearing surface to hold DTUs or FTUs of different specifications, the upper side of the base 100 is also provided with several threaded holes (not shown in the figure). Thus, when a small DTU or FTU is placed on the bearing surface, it can be fixed on the base 100 by screwing screws into the corresponding threaded holes.

[0034] The base 100 is provided with an adapter at one end, and the base 100 is provided with adjustable wire harnesses at both sides. The wire harnesses are used to fix the connected wire harnesses so that the wire harnesses are neatly wired and easy to maintain later.

[0035] In this embodiment, combined with Figure 3As shown, the adapter assembly includes opposing supports 110. Specifically, the supports 110 are fixedly mounted on the upper side of the base 100 by screws. A rotatable adapter socket 120 is provided between the supports 110, and several connectors 301 are arranged on the adapter socket 120. In the actual testing process, the DTU or FTU placed on the base 100 is connected to the corresponding connectors 301 on the adapter socket 120 through a wiring harness. The adapter socket 120 is connected to different testing equipment (multimeter, oscilloscope, DC power supply tester, etc.) through the wiring harness, so that the DTU or FTU can be quickly tested using different testing equipment.

[0036] In practical use, the adapter socket 120 is rotatably mounted between the support 110, thereby adjusting the orientation of the connector 301 on the adapter socket 120, which facilitates the connection between the wiring harness on the DTU or FTU and the connector 301, making it convenient for practical use.

[0037] In this embodiment, the position of the wire harness assembly is adjustable, so that wire harnesses placed on DTUs or FTUs of different specifications on the bearing surface can be fixed, thereby improving the applicability of the wire harness assembly.

[0038] In this embodiment, combined with Figure 4 As shown, the cable harness assembly includes a cable harness clamp 130 slidably disposed on the base 100. The cable harness clamp 130 is provided with a plurality of cable harness slots 401. The cable harness clamp 130 is fixedly installed on the base 100 by a positioning member.

[0039] In this embodiment, the cable clamp 130 is arranged along the length of the base 100. The cable clamp 130 is made of rubber material, which gives it a certain deformation capability, so as to facilitate the cable harness being snapped into the cable clamp slot 401, so that the cable harness of the DTU or FTU connected to the adapter socket 120 is fixed. At the same time, the cable harness will not be damaged during the process of snapping into the cable clamp slot 401.

[0040] In this embodiment, combined with Figure 3 As shown, the two supports 110 are provided with opposite mounting holes, and the two ends of the adapter socket 120 are provided with mounting shafts 302. One of the two mounting shafts 302 is installed in the mounting hole on the corresponding support 110 through the damping shaft 310, and the other mounting shaft 302 is set through the corresponding mounting hole.

[0041] In this embodiment, the mounting shaft 302 is installed and the mounting shaft 302 is installed in the mounting hole through the damping rotating shaft 310, so that the adapter socket 120 can be rotatably installed between the supports 110. At the same time, the rotation of the adapter socket 120 between the supports 110 has a certain damping, so that the adapter socket 120 can be fixed between the supports 110 when no force is applied, so that the orientation of the plug 301 is fixed.

[0042] One of the mounting shafts 302 has a hollow structure. When it is installed in the corresponding mounting hole, the wire harness connecting the adapter socket 120 and the testing equipment can pass through the mounting shaft 302, thereby avoiding the wire harness interfering with the rotation of the adapter socket 120.

[0043] In this embodiment, the upper side of the base 100 and the two sides are provided with L-shaped grooves 201, and the upper side of the base 100 is provided with strip grooves 202 that connect to the corresponding grooves 201 along the extension direction of the grooves 201.

[0044] The positioning component includes a slider 410 that is slidably disposed in the slide groove 201, the wire clamp 130 being fixedly connected to the end of the slider 410 that extends out of the slide groove 201, and a first hand-tightening bolt 420 being provided on the base 100 through the strip groove 202 and threadedly connected to the slider 410.

[0045] In actual use, the slide groove 201 is set to open at both ends of the base 100, so that the slider 410 can slide into the slide groove 201, thereby realizing the installation of the wire clamp 130 on the upper side of the base 100.

[0046] Specifically, the slider 410 is provided with a threaded hole corresponding to the strip groove 202. The first hand-tightening bolt 420 passes through the strip groove 202 and is threaded into the threaded hole. When the first hand-tightening bolt 420 is tightened to press against the upper side of the base 100, the slider 410 can be fixed, thus fixing the wire clamp 130. When the first hand-tightening bolt 420 is loosened to release the pressure between it and the upper side of the base 100, the wire clamp 130 can slide along the slide groove 201 to adjust its position.

[0047] In this embodiment, the base 100 is provided with a limiting member for limiting the DTU or FTU placed on the base 100.

[0048] In actual use, this embodiment uses a limiting component to limit the size of the DTU or FTU placed on the base 100, so as to prevent the DTU or FTU from shaking during testing, thereby affecting the testing.

[0049] Combination Figure 5As shown, in this embodiment, the upper side of the base 100 is provided with a sliding groove 203 with a T-shaped cross section. Specifically, the sliding groove 203 is provided along the extension direction of the sliding groove 201.

[0050] The limiting component includes an L-shaped abutment plate 210, on which a sliding block 501 is provided that slides within a sliding groove 203, and a second hand-tightening bolt 510 for fixing the abutment plate 210 is threadedly connected.

[0051] In actual use, this embodiment achieves a better sliding installation of the abutment 210 on the base 100 by the cooperation of the sliding block 501 and the sliding groove 203; wherein, the sliding groove 203 is provided to open towards both ends of the base 100, so that the abutment 210 can be slidably installed on the base 100.

[0052] In this embodiment, the base 100 is provided with opposing abutment plates 210. A larger DTU or FTU is placed on the base 100 between the abutment plates 210. By moving the abutment plates 210 so that one side wall of the abutment plate is in contact with the DTU or FTU, the second hand-tightening bolt 510 is then turned to press the upper side of the base 100 to fix the abutment plates 210. This allows the two abutment plates 210 to limit the size of the larger DTU or FTU and prevent it from shaking. When the second hand-tightening bolt 510 is loosened, the fixation of the abutment plates 210 is released, allowing the abutment plates 210 to move and adjust along the sliding groove 203 so that the DTU or FTU can be picked up and put on the base 100.

[0053] The abutment 210 has a protective pad on its side wall facing the DTU or FTU to prevent damage to the surface of the DTU or FTU when the abutment 210 is in contact with the DTU or FTU.

[0054] Specifically, in order to improve the effect of the second hand-tightening bolt 510 in fixing the abutment 210, a rubber pad is provided at the end of the upper side of the second hand-tightening bolt 510 pressing the base 100. The rubber pad can increase the friction between the two, so that the effect of fixing the abutment 210 is better.

[0055] In this embodiment, the lower side of the base 100 is provided with mutually perpendicular channels 101, wherein the channels 101 are in the shape of a grid, so as to use mechanical equipment to move the base 100, thereby facilitating the transfer and use of the inspection docking fixture.

[0056] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
