The embodiments described below by way of example with reference to the accompanying drawings are illustrative and are intended to explain the present application, and are not to be understood as limiting the present application.

[0042] A CT terminal shorting piece assembly 100 according to an embodiment of the present application is described below with reference to the accompanying drawings. As shown in Figures 1 to 5 The CT terminal shorting piece assembly 100 according to the embodiment of the present application includes a mounting part 1, a plurality of shorting pieces 2, a limiting member, an insulating handle 3, and an elastic member 6.

[0043] The mounting part 1 is a metal piece, and has a mounting cavity 11, a first sliding hole 12, and a first inlet 13. The first sliding hole 12 is formed on an outer wall surface of the mounting part 1 and communicates with the mounting cavity 11. The first inlet 13 communicates with the mounting cavity 11 and the first sliding hole 12. Each of the mounting cavity 11 and the first sliding hole 12 has a size in a first direction that is greater than or equal to a preset value.

[0044] Each shorting piece 2 is provided with a fixing block 21 that is electrically conductive with the mounting part 1. The fixing block 21 can enter the mounting cavity 11 from the first inlet 13, and the shorting piece 2 can enter the first sliding hole 12 from the first inlet 13. The plurality of fixing blocks 21 can be arranged in the mounting cavity 11 along the first direction. The limiting member can extend into the mounting cavity 11. The insulating handle 3 is connected to the mounting part 1, and at least part of the insulating handle 3 is made of an insulating material. The elastic member 6 is connected to the limiting member and can abut at least part of the limiting member against the fixing block 21 located in the mounting cavity 11 and adjacent to the first inlet 13.

[0045] According to the CT terminal shorting piece assembly 100 of the embodiment of the present application, the mounting portion 1 is provided, and each shorting piece 2 is provided with a fixing block 21, so that when the plurality of fixing blocks 21 are arranged in the mounting cavity 11 of the mounting portion 1 along the first direction, the plurality of shorting pieces 2 can be arranged along the first direction. In addition, the mounting portion 1, the fixing block 21 and the mounting portion 1 can be conductive to each other. Thus, after a preset number of shorting pieces 2 are needed, the fixing blocks 21 of the appropriate number of shorting pieces 2 are placed in the mounting cavity 11, at least part of the limiting member is used to extend into the mounting cavity 11, and the elastic member 6 drives at least part of the limiting member to abut against the fixing block 21 located in the mounting cavity 11 and adjacent to the first inlet 13, so as to limit the fixing block 21 and the shorting piece 2, thereby facilitating the shorting of the CT terminal shorting piece assembly 100, and improving the operation convenience and work efficiency. In addition, the CT terminal shorting piece assembly 100 of the embodiment of the present application is further provided with the insulating handle 3 connected with the mounting portion 1, so that the worker can hold the insulating handle 3 to operate the CT terminal shorting piece assembly 100, so that the worker will not directly contact the shorting piece 2, and the influence such as electric shock and circuit discharge of the worker when the live CT circuit is shorted during the implementation of the electrical secondary measures is prevented, so that the work is safer.

[0046] Therefore, the CT terminal shorting piece assembly 100 of the embodiment of the present application has the advantages of convenient operation, high work efficiency and high safety.

[0047] As shown in Figures 1 to 5 , the CT terminal shorting piece assembly 100 of the embodiment of the present application comprises a mounting portion 1, a plurality of shorting pieces 2, a limiting member, an insulating handle 3 and an elastic member 6

[0048] The mounting portion 1 is a metal piece, and the mounting portion 1 has a mounting cavity 11, a first sliding hole 12 and a first inlet 13. The first sliding hole 12 is formed on the outer wall surface of the mounting portion 1 and communicates with the mounting cavity 11, and the first inlet 13 communicates with the mounting cavity 11 and the first sliding hole 12. The size of each of the mounting cavity 11 and the first sliding hole 12 in the first direction is greater than or equal to a preset value. Specifically, the mounting portion 1 is a (metal) plate body extending along the first direction, and the first inlet 13 is formed on the end portion of the mounting portion 1. The first direction can be a front-rear direction, as shown by the arrow in the figure. For example, the mounting portion 1, the mounting cavity 11 and the first sliding hole 12 are all in the front-rear direction, and the first inlet 13 is an inlet of the mounting cavity 11 and the first sliding hole 12 formed on the front side of the mounting portion 1.

[0049] As shown in Figure 2 and Figure 5As shown in the drawings, each shorting piece 2 is provided with a fixing block 21, the fixing block 21 is a metal piece, the fixing block 21 is electrically conductive with the mounting portion 1. The fixing block 21 can enter the mounting cavity 11 from the first inlet 13 and the shorting piece 2 can enter the first sliding hole 12 from the first inlet 13, and a plurality of fixing blocks 21 can be arranged in the first direction in the mounting cavity 11. Specifically, the fixing block 21 is connected with the shorting piece 2 to position the shorting piece 2, so that a plurality of shorting pieces 2 can be arranged in the first direction. For example, the left end of the shorting piece 2 is connected with the fixing block 21.

[0050] As shown in the drawings, Figure 1 , Figure 2 and Figure 5 in some embodiments, a second sliding hole 14 is formed in the outer wall surface of the mounting portion 1 and communicates with the mounting cavity 11 and the first inlet 13, the size of the second sliding hole 14 in the first direction is greater than or equal to a predetermined value, and the first sliding hole 12 and the second sliding hole 14 are oppositely arranged in the second direction. The second direction can be the left-right direction, as shown by the arrow in the figure. For example, the first sliding hole 12 and the second sliding hole 14 both extend in the front-rear direction, and the first sliding hole 12 and the second sliding hole 14 are oppositely arranged in the left-right direction and penetrate the outer wall surface of the mounting portion 1.

[0051] The size of each of the mounting cavity 11 and the fixing block 21 in the third direction is greater than or equal to the size of each of the first sliding hole 12 and the second sliding hole 14 in the third direction, and any two of the first direction, the second direction and the third direction are perpendicular to each other. Specifically, the size of the shorting piece 2 in the third direction is less than or equal to the first sliding block 12, so that the fixing block 21 can enter the mounting cavity 11 without being pulled out of the first sliding hole 12. The third direction can be the up-down direction, as shown by the arrow in the figure. For example, the size of each of the mounting cavity 11 and the fixing block 21 in the up-down direction is greater than or equal to the size of each of the first sliding hole 12 and the second sliding hole 14 in the up-down direction.

[0052] As shown in the drawings, Figure 2 the side of the fixing block 21 away from the shorting piece 2 in the second direction is provided with a protrusion 22, the protrusion 22 can enter the second sliding hole 14 from the first inlet 13 and can slide in the second sliding hole 14 in the first direction. Specifically, the size of the protrusion 22 in the third direction is less than or equal to the size of the second sliding hole 14. Thus, when the fixing block 21 moves, the protrusion 22 can limit the fixing block 21 in the third direction, so that the shorting piece 2 does not deviate, i.e. the shorting piece 2 is in the correct position. For example, the protrusion 22 can slide in the second sliding hole 14 in the front-rear direction.

[0053] As shown in the drawings, Figure 5As shown in the drawings, in some embodiments, the outer circumferential side of the end of the shorting piece 2 connected with the fixing block 21 is provided with a limiting sleeve 23, the limiting sleeve 23 can enter the first sliding hole 12 from the first inlet 13 and can slide in the first sliding hole 12 in the first direction. Specifically, the limiting sleeve 23 is smaller than the first sliding hole 12 in the third direction by a preset value. Thus, the limiting sleeve 23 can limit the fixing block 21 in the third direction when the fixing block 21 moves, so that the shorting piece 2 does not deviate, that is, the shorting piece 2 is in the correct position.

[0054] As shown in the drawings, Figure 5 As shown in the drawings, in some embodiments, the mounting cavity 11 includes a first cavity 111 and a second cavity 112 opposite in the third direction. Specifically, the opening of the first cavity 111 and the opening of the second cavity 112 are arranged opposite in the third direction. For example, the upper part of the mounting cavity 11 defines the first cavity 111 with the opening downward, and the lower part of the mounting cavity 11 defines the second cavity 112 with the opening upward.

[0055] The thickness direction of the fixing block 21 is the second direction, the fixing block 21 includes a first part, a second part and a third part connected in sequence in the third direction, the first part can extend into the first cavity 111, the second part is connected with the shorting piece 2 and the protrusion 22, and the third part can extend into the second cavity 112. Specifically, the fixing block 21 is plate-shaped, and the first part and the third part of the fixing block 21 extend into the first cavity 111 and the second cavity 112 respectively, so that the fixing block 21 moves more stably. For example, the upper part of the fixing block 21 can extend into the first cavity 111, the middle part of the fixing block 21 is connected with the shorting piece 2 and the protrusion 22, and the lower part of the fixing block 21 can extend into the second cavity 112.

[0056] As shown in the drawings, Figures 1 to 3 As shown in the drawings, the insulating handle 3 is connected with the mounting part 1, at least part of the insulating handle 3 is made of insulating material. The mounting part 1 and the insulating handle 3 are connected through the connecting part 4, the length direction of the insulating handle 3 is the first direction, and the mounting part 1 and the insulating handle 3 are arranged opposite in the second direction. Specifically, the connecting part 4 is a circular arc plate, the two ends of the circular arc plate are connected with the mounting part 1 and the insulating handle 3 respectively, and the mounting part 1 and the insulating handle 3 are arranged in parallel. Thus, the overall volume of the CT terminal shorting piece assembly 100 is small, which is suitable for various operating environments. For example, the insulating handle 3 is located on the left side of the mounting part 1.

[0057] In some embodiments, the insulating handle 3 is provided with a soft rubber pad 31, the soft rubber pad 31 is provided with anti-skid protrusions 32, and the soft rubber pad 31 is located on both sides of the insulating handle 3 in the third direction. Thus, it is convenient for the worker to hold the insulating handle 3. For example, the soft rubber pad 31 is located on both sides of the insulating handle 3 in the up-down direction.

[0058] As shown in the drawings, Figure 4As shown, the limiting member can extend into the mounting cavity 11 and limit the fixing block 21 located in the mounting cavity 11. The limiting member includes a limiting block 5, a limiting post 54, a first nut 55, and a second nut 56.

[0059] The insulating handle 3 has a limiting slot 33 extending through it in a second direction, and the dimension of the limiting slot 33 in the first direction is greater than or equal to a preset value. A second sliding hole 14 is formed on the side of the mounting portion 1 facing the insulating handle 3. For example, the second sliding hole 14 is located on the left side of the limiting block 5.

[0060] The limiting block 5 (at least partially) can enter the mounting cavity 11 and the second sliding hole 14 from the first inlet 13 and can slide in the mounting cavity 11 and the second sliding hole 14 in a first direction. The limiting post 54 extends in a second direction and is slidably disposed in the limiting slot 33 in the first direction. The first end of the limiting post 54 is connected to the limiting block 5. The outer surface of the limiting post 54 is provided with threads. The first nut 55 and the second nut 56 are respectively located on both sides of the insulating handle 3 in the second direction. The first nut 55 and the second nut 56 are sleeved on the limiting post 54 and threadedly connected to the limiting post 54. Thus, after the limiting block 5 enters the mounting cavity 11 and abuts against the fixing block 21 in the first direction, the first nut 55 and the second nut 56 move in a mutually adjacent direction in the second direction to limit the limiting post 54, thereby facilitating the sliding of the limiting post 54.

[0061] like Figure 4 As shown, in some embodiments, the limiting block 5 includes a first plate 51 and a second plate 52.

[0062] The first plate 51 is movably disposed within the mounting cavity 11 along a first direction, and the thickness directions of the first plate 51 and the second plate 52 are both along a second direction. The first plate 51 and the second plate 52 are connected by an intermediate plate 53, which is movably disposed within the second sliding hole 14 along the first direction. The second plate 52 is slidably connected to the mounting part 1 on the side facing the insulating handle 3, and is connected to the limiting post 54. Specifically, the upper part of the first plate 51 can enter the first cavity 111, and the lower part of the second plate 52 can enter the second cavity 112. The first plate 51, the intermediate plate 53, and the second plate 52 form an H-shaped structure, which allows the limiting block 5 to cooperate with the mounting cavity 11 and the second sliding hole 14, thereby making the movement of the limiting block 5 on the mounting part 1 more stable.

[0063] like Figure 1 As shown, the elastic member 6 is connected to the limiting member and can abut at least a portion of the limiting member against the fixing block 21 located in the mounting cavity 11 and adjacent to the first inlet 13.

[0064] In some embodiments, one end of the elastic member 6 is connected to the connecting portion 4, and the other end of the elastic member 6 is connected to the limiting post 54, so that the limiting post 54 can move in a first direction toward the adjacent connecting portion 4. Specifically, the limiting post 54 is provided with a third nut 61 threadedly connected to it, and the elastic member 6 is a spring, one end of which is hung on the third nut 61, and the other end of which is fixed to the connecting portion 4. This allows the spring to drive the limiting post 54 and the limiting block 5 to move in a first direction toward the adjacent connecting portion 4, so that the limiting block 5 abuts against the fixing block 21 located in the mounting cavity 11 and adjacent to the first inlet 13, thereby limiting the fixing block 21. For example, the front end of the spring is hung on the third nut 61, and the rear end of the spring is fixed to the connecting portion 4, so that the spring can drive the limiting post 54 and the limiting block 5 to move backward.
