DETAILED DESCRIPTION

[0037] In order to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0038] Example 1

[0039] See also Figure 1-3 As shown, an embodiment of the utility model provides a cascade module, which is used in a horizontal terminal power distribution system to realize communication cascade between different busbars, prefabricated cables, on-site quick connection, power supply redundant cascade between different busbars, prefabricated cables, on-site quick connection, and connection with a monitoring host, prefabricated cables, and support for redundant power supply.

[0040] Specifically, the cascade includes an upper shell 1 and a lower shell 2 mounted opposite to the upper shell 1, an accommodating space is formed between the upper shell 1 and the lower shell 2, a control board 3 is arranged in the accommodating space, the control board 3 is fixed on the lower shell 2, mounting plates 4 are arranged at both ends of the lower shell 2, a spring pin group 46 is arranged in the mounting plate 4, and the spring pin group 46 electrically connects the control board 3 and the composite busbar; the structure combining the control board 3, the mounting plate 4 and the spring pin group 46 is called a power taking device, such as Figure 4 and 5 As shown. The power taking devices are modular and universal in design, and adopt a universal spring pin structure. Such universal design greatly reduces the cost and improves the production efficiency.

[0041] In order to improve the versatility of the cascade module, the two ends of the upper shell 1 extend outward to form a first card board 11 and a second card board 12, respectively. The first card board 11 and the second card board 12 are arranged on both sides of the composite busbar; a plurality of aviation plugs 5 are arranged on the first card board 11 and / or the second card board 12.

[0042] In order to improve the stability between the cascade module and the busbar, knob plungers 6 are respectively provided on the first clamping plate 11 and the second clamping plate 12. The knob plunger 6 abuts against one side of the composite busbar and is used to fix and loosen the composite busbar when the knob plunger 6 is rotated in different directions.

[0043] In summary, due to the above structure of the cascade module, it can be plugged into any position of the busbar, and then the knob plunger 6 can be rotated to fix the stability between it and the busbar.

[0044] In this embodiment, Figure 6 and 7 As shown, the mounting plate 4 includes a horizontal plate 41, and positioning members 42 are provided at both ends of the horizontal plate 41, and the positioning members 42 are connected to the control plate 3. A vertical groove 43 is provided at the lower middle part of the horizontal plate 41, and the notch of the vertical groove 43 is connected to the horizontal plate 41. A plurality of first through holes 44 are provided at the bottom of the vertical groove 43, and the plurality of first through holes 44 are all provided on the side walls of the vertical groove 43. A plurality of semicircular grooves 45 are provided on the side walls of the vertical groove 43 in the groove depth direction from the notch to the bottom of the groove, and the semicircular grooves 45 are correspondingly connected with the first through holes 44, and the spring pin group 46 is inserted into the first through hole 44 along the semicircular grooves 45 on the side wall. The first through hole 44 is provided on a boss 10 with a certain height, and the boss 10 is provided from the bottom of the groove to the notch, and its purpose is to increase the depth of the through hole, thereby providing the positioning ability of the spring pin, and making its clamping more stable.

[0045] The aviation plug 5 of this embodiment includes two five-core aviation plugs, each of which includes a DC power line and a communication line, and uses standard cables to connect to the required equipment. The spring pin groups 46 at both ends are respectively connected to the DC power bus and the communication bus in the same bus.

[0046] Therefore, in summary, the cascade module is divided into the starting cascade unit according to the function, which leads out the communication bus and DC24V bus of the composite bus. The corresponding standard cable has a 5P aviation socket at one end for connecting the starting cascade unit, and a 2*3 MX3.0 socket at the other end for connecting the equipment. Any equipment that needs to be connected to the system can use the starting cascade unit for simple access. Each starting cascade unit can connect to 2 devices. In actual applications, the starting cascade unit is usually installed at the front end of the bus close to the starting box for access to the monitoring device and monitoring screen of the starting unit.

The spring pin groups 46 at both ends are cascaded with the DC power bus corresponding to different buses or cascaded with the communication bus corresponding to different buses, and are called tail end cascade units based on their functions.

[0049] Specifically, the two aviation sockets of the peripherals are 3P and 4P, one each. The 4P socket is a DC24V power cable, 2 positive and 2 negative, which can improve the power supply capacity and prevent fooling, and the 3P socket is a 485 communication line (A, B, PE); correspondingly, there are two standard cables, namely a power cascade cable with 4P at both ends and a communication cascade cable with 3P at both ends. In actual applications, the tail cascade unit is usually installed at a position far away from the starting box at the rear end of the bus, and is used to cascade the power bus and communication bus in the composite bus of two independent bus sections (such as A bus and B bus); the cascading of the power bus can realize the DC24V redundant power supply function of different buses, which is configured on demand, and the cascading of the communication bus can realize the cascading of communication cables of different buses, which is configured on demand according to the communication topology design.
