[0024] Example

[0025] like Figure 1-4As shown, a quick wiring device for substation maintenance includes a first shell 1 and a second shell 2, wherein the inner sides of the first shell 1 and the second shell 2 are provided with a placement groove 8, and the placement groove 8 is arranged in a square shape, and the width of the placement groove 8 is the same as the diameter of the wire 13, which can ensure that when adjacent inner cores 1301 are clamped together, there will be no mutual offset phenomenon, and the inner sides of the first shell 1 and the second shell 2 are both slidably connected with a clamping block 6, and one end of the clamping block 6 is provided with a limiting mechanism, and the adjacent wires 13 are placed in the placement groove 8 on the inner sides of the first shell 1 and the second shell 2, and at the same time, the inner cores 1301 of the adjacent wires 13 are superimposed together, and the inner cores 13 are placed between the clamping blocks 6, so that the clamping blocks 6 clamp and fix the superimposed inner cores 1301, so that the inner cores 1301 on both sides are tightly fitted together, thereby realizing quick wiring.

[0026] As a further improvement of the utility model, Figure 2 , Figure 3 and Figure 4 As shown, the bottom end of the clamping block 6 is fixedly connected with an extrusion block 7. Since the insulating skin 1302 on the outside of the wire 13 is elastic, the extrusion block 7 and the insulating sheet 1302 are squeezed and fixed together, so that the wire 13 is limited and fixed by the extrusion block 7 and the insulating skin 1302. At the same time, the clamping block 6 clamps and fixes the connection of the inner core 1301, thereby further improving the firmness of the connection between adjacent wires 13.

[0027] As a further improvement of the utility model, Figure 1 , Figure 2 and Figure 3 As shown, the limiting mechanism includes a threaded ring 4 spirally connected to the first shell 1, one end of the threaded ring 4 is fixedly connected to the limiting ring 5, and the limiting ring 5 is movably arranged between the clamping block 6, and the limiting ring 5 can also move along the clamping block 6 while rotating on the outside of the clamping block 6, thereby ensuring the normal operation of the limiting ring 5 on the surface of the clamping block 6, and the number of the threaded rings 4 is two, and they are symmetrically distributed on both sides of the vertical center line of the first shell 1, by rotating the threaded rings 4 and the limiting rings 5 ​​on both sides in opposite directions, the clamping block 6 and the extrusion block 7 can clamp the wires 13 on both sides under the extrusion of the limiting ring 5, and the device can complete the operation by rotating the limiting rings 5 ​​and the threaded rings 4 on both sides, the process is single and the operation is simple, and no special tools are required, which is convenient for the staff to use.

[0028] As a further improvement of the utility model, Figure 1 , Figure 2 and Figure 3As shown, a first wedge surface 11 is provided at one end of the clamping block 6, and a second wedge surface 12 is provided on the inner side of the limiting ring 5, and the first wedge surface 11 is in contact with the second wedge surface 12. With the mutual cooperation between the first wedge surface 11 and the second wedge surface 12, the clamping block 6 can be moved toward the direction close to the conductor 13.

[0029] As a further improvement of the utility model, Figure 1 , Figure 2 and Figure 3 As shown, threads are provided on the outer sides of the first shell 1 and the second shell 2, and the threads on both sides of the vertical center line of the first shell 1 and the second shell 2 are provided in opposite directions, and the threads on both sides of the vertical center line of the first shell 1 and the second shell 2 match the threads on the inner side of the threaded ring 4 on both sides of the vertical center line of the first shell 1. After the first shell 1 and the second shell 2 are fitted together, the threads on the outer sides of the first shell 1 and the second shell 2 form a complete thread circle, which can ensure that the threaded ring 4 on the outer sides of the first shell 1 and the second shell 2 can rotate normally in a spiral manner, so that the threaded rings 4 on both sides rotate in opposite directions, thereby facilitating the staff to exert force and enabling the staff to quickly rotate the threaded ring 4.

[0030] As a further improvement of the utility model, Figure 1 , Figure 2 and Figure 3 As shown, semi-sealing rings 3 are fixedly connected to the inner sides of both ends of the first shell 1 and the second shell 2, and the semi-sealing rings 3 are made of rubber rings. The diameter of the semi-sealing rings 3 is smaller than the diameter of the wire 13, for example, smaller than 1 mm or 2 mm. At the same time, since the semi-sealing rings 3 are elastic, the two semi-sealing rings 3 can be tightly clamped together with the insulating skin 1302 on the outside of the wire 13, thereby ensuring that external foreign objects will not enter the inner sides of the first shell 1 and the second shell 2.

[0031] As a further improvement of the utility model, Figure 3 As shown, the bottom end of the first shell 1 is fixedly connected to a limit pin 9, and the inner side of the top end of the second shell 2 is provided with a limit hole 10 adapted to the limit pin 9. Through the mutual engagement and limiting of the limit pin 9 and the limit hole 10, the first shell 1 and the second shell 2 can be aligned and fitted together to prevent relative movement between the first shell 1 and the second shell 2 when the threaded ring 4 is sleeved on the outside of the first shell 1 and the second shell 2.

[0032] Workflow: When the substation is repaired and wired, the adjacent wires 13 are first passed through the threaded rings 4 and the limiting rings 5 ​​on both sides, and the adjacent wires 13 are first placed on the inner side of the placement groove 8 on the inner side of the second shell 2, and the inner core 1301 on the inner side of the wire 13 is on one side of the clamping block 6, and the insulating skin 1302 on the outer side of the wire 13 is placed on one side of the extrusion block 7, and then the first shell 1 and the second shell 2 are fitted together, and the limiting pin 9 at the bottom end of the first shell 1 is engaged with the limiting hole 10 on the inner side of the second shell 2, and then the staff makes the threaded rings 4 on both sides with the first shell 1 and the second shell The bodies 2 are spirally connected together, so that the threaded rings 4 on both sides rotate in opposite directions with the corresponding limiting rings 5. At the same time, the threaded rings 4 on both sides will also move with the corresponding limiting rings 5 ​​in the direction of approaching each other, so that the limiting rings 5 ​​can squeeze the clamping block 6. Under the squeezing of the limiting rings 5, the clamping block 6 and the squeezing block 7 can clamp the inner cores 1301 and the insulating skin 1302 on both sides, thereby realizing quick wiring. The device can complete the operation by rotating the limiting rings 5 ​​and the threaded rings 4 on both sides. The process is single and the operation is simple, and no special tools are required, which is convenient for staff to use.
