Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] This embodiment is an adjustable-size current transformer mounting strip.

[0025] like Figure 1-4 As shown, it includes a first concave mounting strip 1 and a second concave mounting strip 2. The outer wall of the second concave mounting strip 2 and the inner wall of the first concave mounting strip 1 are slidably connected. The outer surfaces of the upper and lower ends of the second concave mounting strip 2 are provided with second snap-fit ​​holes 8 at the ends near the first concave mounting strip 1. The inner cavity of the second concave mounting strip 2 is fixedly installed with a snap-fit ​​assembly 7 at the end near the second snap-fit ​​hole 8. The snap-fit ​​assembly 7 includes a fixing block 9, a through hole 10, a snap pin 11, a mounting cavity 12, a partition 13, a compression spring 14, and a limiting block 15. The outer surfaces of the upper and lower ends of the first concave mounting strip 1 are provided with first snap-fit ​​holes 5 at equal intervals. The left and right ends of the rear ends of the outer surfaces of the upper and lower ends of the first concave mounting strip 1 are fixedly installed with first ear plates 3. The rear ends of the outer surfaces of the upper and lower ends of the second concave mounting strip 2 away from the first concave mounting strip 1 are fixedly installed with second ear plates 4.

[0026] Mounting holes 6 are provided on both the upper and lower sides of the outer surface of the front end of the first concave mounting strip 1 and the second concave mounting strip 2; the size of the second snap-fit ​​hole 8 is the same as that of the first snap-fit ​​hole 5, and the upper outer wall of the snap pin 11 is snapped into the second snap-fit ​​hole 8 and the first snap-fit ​​hole 5; the fixing block 9 is fixedly installed in the inner cavity of the second concave mounting strip 2 at one end near the second snap-fit ​​hole 8, the through hole 10 is opened in the middle of the outer surface of the upper and lower ends of the fixing block 9, and the mounting cavity 12 is opened inside the fixing block 9, the through hole 10 and the mounting cavity 1 2. The partition 13 is fixedly installed in the middle of the mounting cavity 12; the locking pin 11 passes through the through hole 10; the compression spring 14 is fixedly installed between one side of the outer surface of the partition 13 and one side of the outer surface of the limiting block 15; the locking pin 11 is fixedly installed on the other side of the outer surface of the limiting block 15; the outer wall of the locking pin 11 is slidably connected to the through hole 10; the outer wall of the limiting block 15 is slidably connected to the mounting cavity 12; the lower outer surface of the limiting block 15 is elastically connected to the partition 13 through the compression spring 14.

[0027] It should be noted that this utility model is an adjustable-size current transformer mounting strip, which includes a first concave mounting strip 1 and a second concave mounting strip 2. The second concave mounting strip 2 slides along the inner wall of the first concave mounting strip 1, allowing the overall length of the current transformer mounting strip to be adjusted, thus improving its applicability. The snap-fit ​​component 7 is provided, as shown in the attached instruction manual. Figure 1 As shown, at this time, the locking pin 11 in the locking assembly 7 is locked between the second locking hole 8 and the first locking hole 5. When the length needs to be adjusted, the locking pin 11 is squeezed, and the locking pin 11 slides along the through hole 10. The locking pin 11 drives the limiting block 15 to squeeze the compression spring 14 in the mounting cavity 12. The locking pin 11 separates from the first locking hole 5 and pushes the second concave mounting strip 2, so that the second concave mounting strip 2 slides along the inner wall of the first concave mounting strip 1. When the locking pin 11 reaches the lower end of the other set of first locking holes 5, the reaction force of the compression spring 14 drives the upper end of the locking pin 11 to lock between the second locking hole 8 and the first locking hole 5, thereby achieving the limiting. Therefore, by setting the locking assembly 7, it is convenient to limit the second concave mounting strip 2 and the first concave mounting strip 1, and it is easy to operate, so that the length of the current transformer mounting strip can be easily adjusted, which is more suitable for the installation conditions on site.
