[0002] The electromechanical node is a key part in the electromechanical system, usually referring to the control cabinet, which is the interface point or connector connecting each part.
[0003] An electromechanical system usually contains several electromechanical nodes. For the convenience of repair and maintenance, electromechanical nodes with the same or specific functions are usually placed together to form node modules. Node modules with different specific functions will form a modular form inside the distribution cabinet to facilitate daily maintenance and inspection. When the electromechanical system is running, it is necessary to insert wires into the electromechanical nodes and then connect with other devices through the wires to work together to build a complete electromechanical system. When the wires on the electromechanical nodes are accidentally pulled during maintenance, one end of the wire may become loose at the interface with the electromechanical node, thereby affecting the later use of the electromechanical node, and also increasing the duration of maintenance and inspection and reducing the efficiency of maintenance and inspection.

[0020] The effect achieved by the above components is: by setting a spring, after pulling the card block outward to a certain distance, the spring is stretched, and after releasing the hand, the spring will reset one end of the card block to be more firmly stuck in the card slot and not easy to slide out.
[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

When the node module 4 is installed in the distribution cabinet 1 for control use, an electric wire is used to insert one end of the node module 4 into the interface, and then the other end is passed through the fixed plate 21 and the rectangular hole plate 23 to connect it to other electrical equipment in the distribution cabinet 1. At this time, the threaded rod 22 is rotated on the fixed plate 21 to a certain number of circles, and the rectangular hole plate 23 is driven to move toward the fixed plate 21 under the limiting action of the limiting rod 24, so that the passed electric wire is fixed and limited. In this way, if the electric wire is accidentally pulled during maintenance, one end of the electric wire will not loosen and fall off at the interface with the electromechanical node, thereby reducing the duration of maintenance and inspection and improving the efficiency of maintenance and inspection.
[0029] Reference Figure 1-4 As shown, the present embodiment discloses that one end of the threaded rod 22 is fixedly connected to a plurality of screw blocks 25, and the plurality of screw blocks 25 are arranged at equal distances. By providing the screw blocks 25, the contact area of one end of the threaded rod 22 can be increased, and it is convenient to manually hold and screw it. One end of the threaded rod 22 is fixedly connected to a bearing 26, and the outer ring of the bearing 26 is fixedly connected to one side of the fixed plate 21. By providing the bearing 26, the contact wear between one end of the threaded rod 22 and the fixed plate 21 can be reduced, and the service life of both can be increased.
[0030] Reference Figure 1-4 As shown, the present embodiment discloses that the fixing plate 21 and one side of the rectangular hole plate 23 are both symmetrically fixedly connected with rubber blocks 27, and the rubber blocks 27 are respectively arranged on the opposite sides of the fixing plate 21 and the rectangular hole plate 23. By arranging the rubber blocks 27, the contact friction between the fixing plate 21 and one side of the rectangular hole plate 23 can be increased, and at the same time, the surface of the rubber blocks 27 is relatively soft, so that when the wire is clamped and fixed, it is not easy to be clamped and damaged, and the clamping limit is more secure.
[0031] Reference Figure 1-4As shown, the present embodiment discloses that the adjustment device 3 includes two adjustment rods 31, the two ends of the fixed plate 21 are respectively slidably connected to the inner walls of the two adjustment rods 31, a plurality of slots 32 are provided on one side of the adjustment rod 31, a slot block 33 is symmetrically fixedly connected to one side of the fixed plate 21, a slot block 34 is slidably connected to the inner wall of the slot block 33, and one end of the slot block 34 is inserted into the inner wall of the slot 32. According to the height of the position where the node module 4 is installed, the fixed plate 21 can be manually held and slid upward or downward to a certain position in the inner walls of the two adjustment rods 31, and then the slot block 34 is slid to one side in the inner wall of the slot block 33 to a certain position, so that one end of the slot block 34 is stuck in the corresponding slot 32, so that the adjusted fixed plate 21 can be limited on the adjustment rod 31, which is convenient for clamping and limiting the wires at the interface of the node module 4 at different installation positions, thereby improving the adaptability of the fixed plate 21.
[0032] Reference Figure 1-4 As shown, the embodiment discloses that the inner wall cross section of the adjusting rod 31 is L-shaped, and the cross sections of both ends of the fixing plate 21 are L-shaped. By designing the inner wall of the adjusting rod 31 and the two ends of the fixing plate 21 into an L shape, the fixing plate 21 is not easy to shake left and right when sliding up and down, and the movement is more stable. A pull block 35 is fixedly connected to one side of the clamping block 34, and the longitudinal section of the pull block 35 is rectangular ring-shaped. By setting the pull block 35, when operating the clamping block 34, it is convenient to manually grasp and pull one side of it. A spring 36 is sleeved and connected to the outer surface of one end of the clamping block 34, and the two ends of the spring 36 are fixedly connected to one side of the clamping block 34 and the clamping hole block 33 respectively. By setting the spring 36, after the clamping block 34 is pulled outward to a certain distance, the spring 36 is stretched, and after releasing the hand, under the reset action of the spring 36, one end of the clamping block 34 is more firmly stuck in the clamping slot 32 and is not easy to slide out.
[0033] Working principle: when the node module 4 is installed in the distribution cabinet 1 for control use, an electric wire will be used to insert one end of the node module 4 into the interface, and then the other end will be passed through the rubber block 27 on the fixed plate 21 and the rectangular hole plate 23, and connected to other electrical equipment in the distribution cabinet 1. At this time, hold the screw block 25 to rotate the threaded rod 22 and the bearing 26 on the fixed plate 21 to a certain number of circles. Under the limiting action of the limiting rod 24, the rectangular hole plate 23 is driven to move toward the fixed plate 21 to fix the passing wire. In this way, if the wire is accidentally pulled during maintenance, one end of the wire will not loosen and fall off at the interface with the electromechanical node, thereby reducing the maintenance and inspection time and improving the maintenance and inspection efficiency.
[0034] When the node module 4 is installed at a different height, first manually hold the pull block 35 to pull the card block 34 outward in the inner wall of the card hole block 33 so that one end is pulled out of the card slot 32, driving the spring 36 to be stretched, and then manually hold the fixed plate 21 to slide it upward or downward in the inner walls of the two adjustment rods 31 to a certain position, and then under the resetting action of the spring 36, drive the card block 34 to reset one end and snap into the corresponding card slot 32, so that the adjusted fixed plate 21 can be limited on the adjustment rod 31, which is convenient for clamping and limiting the wires at the interface of the node module 4 at different installation positions, thereby improving the adaptability of the fixed plate 21.
