Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] This utility model provides, for example Figure 1-4 The diagram shows a current transformer for switching.

[0037] Example 1

[0038] The device includes a current transformer body 1, a terminal block 2, and a support assembly 3. The terminal block 2 is mounted on the current transformer body 1. The support assembly 3 is located on the back of the current transformer body 1. The support assembly 3 includes a mounting plate 31, a support plate 32, a connecting assembly 33, and an adjusting assembly. The mounting plate 31 is fixedly mounted on the back of the current transformer body 1. The top of the mounting plate 31 has a connecting groove that matches the support plate 32. The connecting assembly 33 is installed between the support plate 32 and the terminal block 2. Under the action of the connecting assembly 33, the stability of the connection between the support plate 32 and the terminal block 2 can be ensured. The adjusting assembly is located on the mounting plate 31. The adjusting assembly is used to adjust the height of the support plate 32, so that the support plate 32 is in an appropriate position to support the terminal block 2, thereby improving the stability of the terminal block 2 in use.

[0039] Furthermore, the connecting assembly 33 includes a first arc plate 331, a second arc plate 332, a fixing collar 333, a fixing block 334, and a fixing bolt 335. The first arc plate 331 is fixedly connected to the top of the support plate 32, and the second arc plate 332 is rotatably connected to the top of the first arc plate 331. The second arc plate 332 and the first arc plate 331 can be combined to form a ring. The second arc plate 332 and the first arc plate 331 are symmetrically sleeved on the ends of the outer wall of the terminal 2. The fixing collar 333 is fixedly sleeved on the ends of the outer wall of the terminal 2. The inner walls of the second arc plate 332 and the first arc plate 331 are both provided with arc grooves that match the fixing collar 333. The fixing collar 333 is engaged with the second arc plate 331. The second arc plate 332 and the first arc plate 331 are in the arc groove inside the first arc plate 331, thus ensuring the stability of the second arc plate 332 and the first arc plate 331 when they are snapped onto the outside of the terminal 2. The fixing block 334 is fixedly connected to one side of the second arc plate 332 and the first arc plate 331 respectively. The fixing block 334 on one side of the second arc plate 332 and the first arc plate 331 is fixedly connected by fixing bolt 335. The two fixing blocks 334 are fixed by fixing bolt 335, which can fix the second arc plate 332 and the first arc plate 331. By removing the fixing bolt 335, the second arc plate 332 can be rotated relative to the first arc plate 331, thereby removing the second arc plate 332 and the first arc plate 331 from the outside of the terminal 2.

[0040] Example 2

[0041] Based on Embodiment 1, the adjustment assembly includes an adjustment screw 341 and a threaded groove 342. The bottom of the outer wall of the adjustment screw 341 is rotatably connected to the mounting plate 31. The threaded groove 342 is opened at the bottom of the support plate 32. The outer wall of the adjustment screw 341 is threadedly engaged with the inner cavity of the threaded groove 342. By rotating the adjustment screw 341, the adjustment screw 341 can be made to cooperate with the threaded groove 342 on the support plate 32, thereby driving the support plate 32 to slide up and down relative to the connecting groove on the mounting plate 31, thereby changing the height of the top of the support plate 32.

[0042] Furthermore, the adjustment assembly also includes a limiting collar 343 and a knob 344. The limiting collar 343 is fixedly sleeved on the outside of the adjusting screw 341 and is rotatably disposed inside the connecting groove. The knob 344 is fixedly connected to the bottom of the adjusting screw 341. The limiting collar 343 and the knob 344 can ensure the stability of the rotatable connection between the adjusting screw 341 and the mounting plate 31. The knob 344 can drive the adjusting screw 341 to rotate.

[0043] Furthermore, the adjustment assembly also includes positioning grooves 345 and inner bolts 346. Multiple positioning grooves 345 are arranged in a ring array on the outside of the limiting collar 343. The outer wall of the inner bolt 346 is threaded to the mounting plate 31. One end of the outer wall of the inner bolt 346 is slidably engaged with the inner cavity of the positioning groove 345. The engagement of the inner bolt 346 with the positioning groove 345 on the limiting collar 343 can limit the adjustment screw 341, thereby ensuring the stability of the support plate 32 supporting the terminal 2.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
