DETAILED DESCRIPTION

[0041] The present application provides a terminal row support for low-voltage power control cabinet secondary wiring as shown in the figure.

[0045] Further, the inner wall of the wire binding groove 4 is coated with red pigment, when the wire is clamped in the wire binding groove 4, the red pigment is blocked by the wire and is not obvious, when the wire is not installed in the wire binding groove 4, the obvious red pigment can be obviously seen, which can quickly display and judge which wire is missed, and further improve the wiring efficiency.

[0046] Reference Figure 7As shown in the figure, the rubber strip 7 is arranged on the front side of the concave frame, and the rubber strip 7 has elasticity and is distributed along the length direction of the terminal row support 2. The rubber strip 7 is fixed on the terminal row support 2, and the position of the rubber strip 7 corresponding to the wire bundle binding groove 4 can be stretched outward, so that a distance is generated between the rubber strip 7 and the terminal row support 2. The rubber strip 7 is used to preliminarily limit the position of the wire, and does not affect the installation and passing of the wire. Specifically, the wire can be first passed between the rubber strip 7 and the wire bundle binding groove 4, the wire is first compressed by the rubber strip 7, and then the wiring treatment is performed. When the insulating sheath of the wire end is treated, it is not necessary to prevent the wire from falling off in real time, and it is especially suitable for efficient wiring operation.

[0047] Reference Figure 7 And Figure 8 As shown in the figure, the terminal assembly includes an insulating connecting plate 8, a first conductive wire 11, a second conductive wire 12 and a conductive block 14. The insulating connecting plate 8 is arranged in pairs, and one pair of insulating connecting plates 8 is arranged in an upper and lower manner. The upper insulating connecting plate 8 is movably attached to the upper inner wall of the terminal row support 2, and the lower insulating connecting plate 8 is fixedly attached to the lower inner wall of the terminal row support 2. The insulating connecting plate 8 is arranged corresponding to the quick connection groove 3, and the length and width of the insulating connecting plate 8 are greater than those of the quick connection groove 3. A spring 13 is arranged between the upper and lower insulating connecting plates 8. The upper insulating connecting plate 8 is attached to the upper inner wall of the terminal row support 2 by the support force of the first conductive wire 11 and the second conductive wire 12. The conductive block 14 is arranged inside the insulating connecting plate 8. One pair of insulating connecting plates 8 are arranged with a plurality of power connection holes 9 on the side away from each other. The power connection holes 9 are arranged in a plurality of groups, and the power connection holes 9 of each group are arranged to penetrate the insulating connecting plate 8 and reach the surface of the conductive block 14. The upper and lower ends of the first conductive wire 11 are electrically connected to the conductive block 14 inside the upper and lower insulating connecting plates 8, respectively. The middle section of the first conductive wire 11 is provided with the second conductive wire 12, and the resistance of the second conductive wire 12 is slightly higher.

[0048] The wires on each meter and measuring element are respectively electrically connected to the upper and lower insulating connecting plates 8 to achieve the connection purpose. Because the resistance of the second conductive wire 12 is slightly higher, when the current or voltage of the circuit is too large, the second conductive wire 12 will be burned out. Since the second conductive wire 12 is arranged horizontally, after the second conductive wire 12 is broken, the spring 13 can pull the corresponding upper insulating connecting plate 8 downward, so that the insulating connecting plate 8 is completely separated from the wire connection of each meter and measuring element, the circuit is disconnected, and the continuous burning phenomenon caused by the factors that the wires are too close to each other or the fuse itself is still connected after being broken is avoided. That is, when the second conductive wire 12 is disconnected, the circuit is disconnected, there is no continuous excessive current or intermittent current, and the damage to each meter and measuring element is also avoided, thereby reducing the loss.

[0049] The elastic insulation sleeve 10 is arranged outside the first conductive wire 11, and the upper and lower ends of the elastic insulation sleeve 10 are fixedly connected to the upper and lower insulation connecting plates 8 respectively. The elastic insulation sleeve 10 can be elastically deformed and does not affect the lowering of the upper insulation connecting plate 8. The elastic insulation sleeve 10 also serves the purpose of protecting the outside of the first conductive wire 11, the second conductive wire 12 and the spring 13.

[0050] Reference Figures 9-11 As shown in the specification, the application provides a connection mode of each meter and measuring element. Specifically, the connection mode comprises a first wiring board 15 and a second wiring board 16. The first wiring board 15 and the second wiring board 16 are arranged in an upper and lower distribution. The side close to each other of the first wiring board 15 and the second wiring board 16 is provided with a conductive sheet 18. The conductive sheet 18 is used for wire connection.

[0051] The first conductive wire 17 on each meter and measuring element is fixedly connected to the first wiring board 15. The first conductive wire 17 is conductively connected to the conductive sheet 18 on the first wiring board 15. The lower side of the second wiring board 16 is provided with an electrically connected column 22 which is conductively connected to the conductive sheet 18. The electrically connected column 22 is provided with a plurality of electrically connected columns 22. The electrically connected column 22 can be clamped in the corresponding electrically connected hole 9, thereby achieving the purpose of conductive connection between the first conductive wire 17 and the conductive block 14.

[0052] The upper surface of the second wiring board 16 and the lower surface of the first wiring board 15 are both provided with a sealing gasket 21. The sealing gasket 21 is provided with a magnetic ring. The magnetic rings can be fixed by mutual adsorption. The magnetic ring can also be adsorbed and fixed in the quick connection groove 3. The first wiring board 15 and the second wiring board 16 can be stacked and stably fixed in the quick connection groove 3 by magnetic adsorption positioning. The connection is quick without complex wiring and fixing.

[0053] Further, the side close to each other of the first wiring board 15 and the second wiring board 16 is provided with a wiring groove hole 19 and a sealing ring 20. The sealing ring 20 is fixedly arranged on the inner wall of the wiring groove hole 19. When more meters and measuring elements need to be connected to the corresponding terminal assembly, the conductive sheet of the meter and measuring element can be peeled off. Then the conductive copper wire 24 is distributed in a fan shape and is pressed between the first wiring board 15 and the second wiring board 16. The copper wire 24 is quickly fixed due to the pressing effect of the first wiring board 15 and the second wiring board 16. The copper wire 24 does not need to be twisted and tightly wound by screws or other methods. The purpose of quick wiring is achieved.

[0054] Reference Figures 12-13As shown in the middle, when more tables and measuring elements need to be connected, notches can also be opened on the side of the quick connection groove 3, and wire groove holes 19 are arranged at both ends of the first wiring board 15 and the second wiring board 16, and the first conductive wire 17 and the second conductive wire 23 can be respectively connected in the two wire groove holes 19, realizing more modes of connection, and the copper wires 24 at the ends of the first conductive wire 17 and the second conductive wire 23 are all fan-shaped and dispersedly distributed.

[0055] Among them, the second conductive wire 23 is sequentially movable through the wire binding groove 4, the clamping groove 6 and the rubber strip 7, and then extends from above the side of the rubber strip 7 away from the quick connection groove 3, realizing positioning and wire binding of the second conductive wire 23 before covering the cover 5, avoiding mutual entanglement of cables, and then covering the cover 5, it should be noted that the cover 5 is provided with a notch for the second conductive wire 23 to pass through, which is a common design, and will not be repeated here, the distribution mode of the second conductive wire 23 in the present application can increase the strength of the connection of the second conductive wire 23, and avoid the phenomenon of falling off or poor contact of the second conductive wire 23.

[0056] Further, the terminal assembly designed in the present application replaces the exposed wiring terminal in the prior art, which can realize quick and stable connection between wires while making the wiring place not in contact with air, avoiding the phenomenon of high resistance, oxidation, burning and electric spark, and has high safety.

[0057] As an extension, when the terminal assembly at the wiring place is damaged, the spring 13 pulls down the upper insulating connecting plate 8, and the outer surface of the upper insulating connecting plate 8 is coated with red or other conspicuous color, so that it can be clearly observed which terminal assembly is damaged, facilitating quick replacement and maintenance, and whether the terminal assembly is replaced alone or the upper and lower tables or measuring elements of the terminal assembly are replaced, other positions do not need to be disassembled, that is, when the terminal assembly is removed, the second wiring board 16 above and below the terminal assembly is still clamped and fixed in the corresponding quick connection groove 3, and the wiring place does not need to be adjusted, which is simple and convenient.
