An adapter 7 is provided at the output end of one side of the test machine 6, and a docking plate 8 is provided on the other side of the test machine 6. The docking plate 8 is connected to the centralized component through a cable to supply power to the test machine 6 arranged in a group inside the cabinet frame 1, thereby reducing the number of cables to be docked during the power supply process of the test machine 6;

[0045] In conjunction with the accompanying drawings Figure 1-6 As shown, the cabinet frame 1 is a rectangular box structure composed of steel plates and steel frames. Figure 1-3 As shown, the positioning plates 3 equidistantly connected and arranged inside the cabinet frame 1 are sheet-shaped perforated plates. As the bolts penetrate the positioning plates 3 and are connected and limited with the limiting strips 5 and the supporting plates 4, as shown in FIG. Figure 1-3 As shown, the support plate 4 is used to carry the test machine 6. The test machine 6 is used to detect the equipment and collect data through the computer. Since there are many collection items, the test machine 6 needs multiple joint operations when in use. The test machine 6 cooperates with the adapter 7 to dock with the external control computer when in use, which is convenient for data collection and docking. The docking plate 8 set in the test machine 6 hearse is docked with the power supply equipment through a cable. The uninterruptible power supply 15 set at the bottom end of the cabinet frame 1 supplies power to the test machine 6 when the internal circuit of the distribution cabinet is powered off. A gap is left between the bottom end surface of the support plate 4 at the bottom of the cabinet frame 1 and the uninterruptible power supply 15 for air heat dissipation. The uninterruptible power supply 15 is a mature product equipment structure and system sold on the market, which is used to continuously supply power to the test machine 6 to avoid low voltage, surge, spike, interference and other states, provide assistance for the work of the test machine 6, and constitute a second set of power supply equipment;

[0046] Centralized components include:

[0047] A voltage transformer 9, which is connected to the docking plate 8 via a cable;

[0052] A cable tie 14 is equidistantly arranged on the surface of the limit strip 5 near the side of the installation box 11 by bolts. The cable tie 14 is arranged as an E-shaped frame structure, and one side opening of the cable tie 14 is engaged with one side of the limit strip 5;

[0053] In conjunction with the accompanying drawings Figure 1-6As shown, when in use, the installation box 11 is slidably connected to the cabinet frame 1 through the guide rods 12 symmetrically arranged on both sides. Figure 1-3 As shown, the guide rod 12 and the limiting sleeve 13 form a sleeved two-stage sliding connection structure, as shown in FIG. Figure 4 As shown, the guide rod 12 is convenient for pulling the installation box 11 to prevent the installation box 11 from falling off due to excessive weight when the centralized power supply 10 and the voltage transformer 9 arranged inside the installation box 11 are connected to the docking plate 8 through cables. Through the setting of the installation box 11, multiple test machines 6 are grouped so that each group of test machines 6 is centrally powered. The docking plug arranged on one side of the centralized power supply 10 is convenient for cable docking, thereby reducing the number of cables that prolapse when the test machines 6 are connected and used, and the cable positions are centralized, thereby reducing the error of plugging the wrong line. The wiring harness 14 arranged below the installation box 11 is installed on the positioning plate 3, the support plate 4 or the limit bar 5 side as needed. Since the positioning plate 3 and the limit bar 5 are arranged in a well shape, the E-shaped structure of the wiring harness 14 is composed of two C-shaped structures. The installation position of the wiring harness 14 is adjusted according to the need for centralized wiring. The bolt passes through the opening on one side of the wiring harness 14 to keep it stable, and the opening on the other side of the wiring harness 14 is for wiring harness gathering, such as Figure 5-6 shown.

[0054] Working principle: When using the test distribution cabinet that is convenient for centralized wiring, the positioning plate 3 and the limit strip 5 are installed in a well shape with bolts to the inner wall of the cabinet frame 1, wherein the positioning plate 3 and the support plate 4 are kept horizontally arranged inside the cabinet frame 1 by bolts to provide assistance for the installation of the test machine 6. The adapter 7 arranged on one side of the test machine 6 is convenient for docking with the test computer of the distribution cabinet for detection. As the docking plate 8 on the other side of the test machine 6 is connected to the voltage transformer 9 with the cable, the centralized power supply 10 and the installation box 11 are arranged equidistantly on one side of the cabinet frame 1 when in use, so that The centralized power supply 10 is directly connected to the cable of the docking plate 8 through the voltage transformer 9, which is convenient for centralized power supply to the test machine 6. The uninterruptible power supply 15 is connected to the centralized power supply 10. When the centralized power supply 10 is powered off, the uninterruptible power supply 15 is started to continuously supply power to form two sets of circuits, so as to keep sufficient power backup for the test machine 6 when in use. The wire harness 14 installed on the surface of the limit strip 5 below the voltage transformer 9 is used to collect redundant cables through an opening on one side, so as to avoid too many cables and clutter in the use of the test machine 6, thereby increasing the overall practicality.
