[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The interface protection structure of the power grid switch cabinet provides two technical solutions:

[0025] like Figure 1-3 The first embodiment is shown: comprising a switch cabinet body 1, a plurality of interface slots 2 are provided at the rear of the switch cabinet body 1, and a wire protection mechanism for protecting the wires led out from the switch cabinet body 1 is provided at each of the plurality of interface slots 2, and the wire protection mechanism comprises:

[0026] The locking assembly 3 is used to compress and protect the wire and prevent the wire from being further pulled out when the wire is pulled. The locking assembly 3 includes an outer cylinder 31 and an inner cylinder 34, and the heads of the outer cylinder 31 and the inner cylinder 34 are both conical. A plurality of card grooves 35 are equidistantly provided on the conical surface of the inner cylinder 34, and steel balls 36 are slidably connected in the plurality of card grooves 35. The inner cylinder 34 is located inside the outer cylinder 31, and a cavity is formed between the inner cylinder 34 and the outer cylinder 31, and a plurality of steel balls 36 are located in the cavity. A first slide groove 32 is provided at the top and bottom of the outer cylinder 31, and push plates 33 are slidably connected to the inner surfaces of the two first slide grooves 32. One end of the two push plates 33 located inside the outer cylinder 31 is fixedly connected to the inner cylinder 34, and a reset spring 37 is fixedly connected between the front surface of the inner cylinder 34 and the front surface of the inner wall of the outer cylinder 31, and the reset spring 37 is used to push the inner cylinder 34 to reset.

[0027] A wire protection mechanism is provided at the interface slot 2 on the power grid switch cabinet. The locking assembly 3 in the wire protection mechanism compresses and protects the portion of the wire after it is led out through a steel ball 36. When the wire is pulled, the steel ball 36 increases the locking of the wire through the cooperation of the inner and outer cylinders, thereby preventing the loosening of the wire and the electrical components caused by the pulling, thereby improving the practicability of the device when in use.

[0028] like Figure 2-4 A second embodiment is shown, which mainly differs from the first embodiment in that: an installation component 4 is arranged on the locking component 3, and is used to quickly install the installation component 4 to the interface groove 2. The installation component 4 includes a connecting cylinder 41 and a mounting annular plate 45. The connecting cylinder 41 is fixedly connected to the front of the outer cylinder 31. Four second sliding grooves 42 are equidistantly provided on the surface of the connecting cylinder 41 in the circumferential direction. The inner surfaces of the four second sliding grooves 42 are slidably connected with L-shaped plates 43. A limiting spring 44 is fixedly connected between the L-shaped plate 43 and the back side of the inner wall of the connecting cylinder 41. Four insertion grooves 46 corresponding to the positions of the four L-shaped plates 43 are equidistantly provided on the inner surface of the mounting annular plate 45 in the circumferential direction. Four limiting bosses 47 are fixedly connected to the front of the mounting annular plate 45 at equal distances.

[0029] The locking assembly 3 is installed at the interface slot 2 through the installation assembly 4, so that the wire protection mechanism can be quickly installed on the power grid switch cabinet, which improves the convenience of using the wire protection mechanism.

[0030] During installation, the installation annular plate 45 is placed inside the switch cabinet body 1, and the connecting cylinder 41 is inserted from the interface groove 2. After insertion, the L-shaped plate 43 enters the insertion groove 46 and passes over the installation annular plate 45. The connecting cylinder 41 is rotated so that the bending part of the L-shaped plate 43 is misaligned with the insertion groove 46, thereby completing the installation. The wires connected to the electrical components in the switch cabinet body 1 pass through the connecting cylinder 41 and the outer cylinder 31 and are led out to the outside of the switch cabinet body 1. When the wires enter the outer cylinder 31, the push plate 33 is pushed to increase the distance between the multiple steel balls 36. At this time, the wires can pass through the outer cylinder 31. After the wire has been passed through, the push plate 33 is released and the inner cylinder 34 is reset under the action of the reset spring 37, and then the outer cylinder 31 and the conical surface are used to move the multiple steel balls 36 between them, thereby pressing the wire tightly. In addition, when the wire is pulled, the wire tends to move outside the outer cylinder 31, and then the friction between the steel balls 36 and the wire drives the inner cylinder 34 to move. The movement of the inner cylinder 34 causes the steel balls 36 to contact the conical surface of the outer cylinder 31. As the inner diameter of the conical cavity gradually decreases, the multiple steel balls 36 are brought closer to the middle, thereby pressing the wire more tightly, thereby preventing the wire from being pulled.
