[0021] As shown in FIG. Figures 1 to 4 A cable terminal box for power distribution equipment, comprising a shell 1 and a shell cover 2 arranged at the front end thereof, a hole 3 is formed in the middle of the shell cover 2, a cover 4 is arranged at the hole 3, a separation plate one 5 is arranged at the opposite ends of the outer wall of the shell 1, a semicircular notch one 6 is formed at the four ends of the shell 1 respectively, two groups of notches two 7 corresponding to the same direction notch one 6 are respectively formed on the two groups of separation plate one 5, the notch two 7 is semicircular, and the inner diameter thereof is consistent with the inner diameter of the notch one 6, a separation plate two 8 is arranged at the opposite ends of the outer wall of the shell cover 2 respectively, a semicircular notch three 9 is formed at the four ends of the shell cover 2, two groups of notches four 10 corresponding to the same direction notch three 9 are respectively formed on the two groups of separation plate two 8, the notch four 10 is semicircular, and the inner diameter thereof is consistent with the inner diameter of the notch three 9,

[0022] Two sets of separation plates 5 are arranged with L-shaped plates 21 facing each other on their adjacent sides, and two sets of separation plates 8 are arranged with L-shaped plates 22 facing each other on their adjacent sides, with L-shaped plates 22 and L-shaped plates 21 arranged one-to-one. L-shaped locking blocks 11 are slidably arranged at all four ends of the inner wall of the cover 4. The shell cover 2 has through grooves 12 on opposite sides that communicate with the holes 3. A slider 13 is vertically slidably arranged at the through grooves 12. One end of the slider 13 is rotatably connected to a connecting plate 15, and the other end of the connecting plate 15 is connected to a driving plate 17. A guide strip 20 is provided on the cover 4, and the driving plate 17 is slidably connected to the cover 4 through the guide strip 20. The upper and lower ends of the driving plate 17 are respectively connected to the two sets of upper and lower opposing locking blocks 11. The connecting plate 15 is slidably connected to the driving plate 17 via the sliding plate 16, and the connecting plate 15 and the sliding plate 16 are rotatably connected. A telescopic spring 18 is vertically installed on the slider 13. The upper and lower ends of the telescopic spring 18 are respectively connected to the upper side of the inner wall of the through groove 12 and the upper side of the slider 13. The purpose is to enable the slider 13 to return to its original position after it moves up and is compressed to the telescopic spring 18. A friction pad 14 is provided on the side of the slider 13 away from the hole 3. The purpose is to increase the friction force of personnel contact and facilitate the movement of the slider 13. An observation window 19 is provided in the middle of the cover 4. The purpose is to allow personnel to clearly see the situation inside the housing 1.

[0023] When fixing the housing 1 and the cover 2, as follows: Figures 1 to 2 As shown, firstly, the two sets of separating plates 5 are attached to the upper and lower sides of the housing 1, so that the L-shaped plate 21 on the separating plate 5 is located at the opening of the housing 1. At the same time, the two sets of separating plates 8 are attached to the upper and lower sides of the cover 2, so that the L-shaped plate 22 on the separating plate 8 is located at the hole 3 of the cover 2. It should be noted that the L-shaped plate 21 and the L-shaped plate 22 have the same shape, and when the cover 2 is attached to the front side of the housing 1, the L-shaped plate 22 and the L-shaped plate 21 are arranged in a front-to-back opposite manner. The initial state of the telescopic spring 18 is the extended state. When the person places the cover 4 on the front side of the cover 2, the slider 13 needs to be pushed up to make the cover 4 open. When block 11 is close to the middle of the cover 4, and the cover 4 is attached to the front side of the shell cover 2, the locking block 11 is located between the corresponding L-shaped plates 21. Then, the slider 13 is released, the telescopic spring 18 is reset, and the slider 13 is moved down, pulling the locking block 11 on the connecting plate 15 to lock the L-shaped plate 22 that the separation plate 28 extends into the hole 3 and the L-shaped plate 21 that the separation plate 15 extends into the shell 1. This makes the separation plate 15 and the separation plate 28 respectively limited to the outer wall of the shell 1 and the outer wall of the shell cover 2. The notch 27 on the separation plate 15 corresponds to the notch 16 on the shell 1, and the notch 410 on the separation plate 28 corresponds to the notch 39 on the shell cover 2.

[0024] When the rusted screw nut of the screw connection is locked, the slider 13 can be pushed up, the slider 13 moves vertically, drives the connecting plate 15 to move up synchronously, the other end of the connecting plate 15 pushes the plate 17 to move close to the middle of the cover 4 through the sliding plate 16, drives the clamping block 11 on both ends of the plate 17 to move away from the L-shaped plate one 21 and the L-shaped plate two 22, the separation plate one 5 and the separation plate two 8 can be separated from the shell 1 and the shell cover 2 respectively, the gap two 7 on the separation plate one 5 is separated from the gap one 6 on the shell 1, the gap three 9 on the separation plate two 8 is separated from the gap four 10 on the shell cover 2, so that the locked screw nut can be taken off from the shell 1 and the shell cover 2, which is convenient and fast.

[0025] The above examples are used to illustrate the present application, but not to limit the present application, and any simple transformation of the present application belongs to the protection scope of the present application.
