The specific working process is as follows: when the wiring device designed by the invention is used, before connection, the two ends of two sections of cables 1 to be connected, which are not peeled off, are fixed on the fixing sleeve 43, then the peeled ends are installed on the connecting device 3, when the connecting device 3 is installed, the fixing sleeve 43 is slightly opened firstly, so that the cables 1 can be conveniently adjusted and inserted, then the conductive parts in the cables 1 are sequentially inserted into the wire insertion holes 8 formed in the installation blocks 7 in the connecting device 3, and when the connecting device 3 is inserted, the inserted conductive parts can extrude the corresponding push discs 23, so that the two push discs 23 in the same wire insertion hole 8 are close to the middle, and the push discs 23 slide to drive the corresponding trigger plates 24 to move; in the process of inserting the cable 1, when the cable 1 cannot be inserted continuously, the cable is considered to be inserted qualified, at the moment, the push disc 23 is contacted with the corresponding positioning block 59, the circular holes 26 on the trigger plates 24 which are matched with each other in the three wire insertion holes 8 are all matched in an aligned manner, when the three insertion rods 22 can be smoothly inserted into the circular holes 26, at the moment, one T-shaped bolt 16 is rotated, two T-shaped bolts 16 simultaneously press the pressing block 5 through gear transmission, the pressing block 5 can drive the six pressing shells 35 to move downwards through the connecting shell 36 arranged on the pressing block 5, the pressing shell 35 moves downwards and drives the corresponding mounting plate 40 to move downwards through the pressing spring, the mounting plate 40 moves downwards and drives the pressing rod 39 on the lower side to move downwards, and the inserted conductive; in the pressing process, after the conductive part is pressed, the pressing shell 35 is pressed continuously, and the pressing shell 35 compresses the extrusion spring 38; the pressing shell 35 moves downwards relative to the mounting plate 40, the relative position between the upper end of the inspection rod 37 mounted on the mounting plate 40 and the inspection square sleeve 11 mounted on the upper end of the pressing shell 35 changes, and when the position change between the inspection rod 37 and the corresponding inspection square sleeve 11 is observed, the inserted conductive component can be judged to be pressed tightly; if the inserted conductive member is not compressed due to loose winding or the like, the position between the upper end of the inspection rod 37 and the corresponding inspection square sleeve 11 is not changed after the T-bolt 16 is driven to move down by a specified amount, and it can be concluded that the inserted conductive member is not compressed, needs to be pulled out, finds a problem, and is inserted again for compression.

If the circular holes 26 of two trigger plates 24 in one of the three wire insertion holes 8 are not aligned after the corresponding conductive member is inserted into the six trigger plates 24 in the three wire insertion holes 8, the plug rod 22 corresponding to the wire insertion hole 8 cannot be inserted downwards into the corresponding circular hole 26, and the two misaligned trigger plates 24 limit the corresponding plug rod 22; at this moment, the pressing block 5 is limited and cannot be pressed down, the six wire pressing units 4 cannot compress the inserted conductive parts, and under the condition, a user needs to pull out the cable 1 and insert the cable again to compress the cable after finding out a problem.

Finally, the cables 1 on both sides are completely fixed by the fixing sleeves 43 so as to facilitate the subsequent winding.

After the connecting device 3 is installed, the motor 52 is controlled to rotate the third gear 56, the third gear 56 drives the gear ring 53 to rotate, the gear ring 53 rotates to drive the winding wheel 44 to rotate, so that the winding wheel 44 rotates around the connected cable 1, the winding belt on the winding wheel 44 is wound on the connected cable 1 during rotation, and the sliding ring 49 can be manually controlled to slide along the length direction of the bracket 45 when the motor 52 controls the winding wheel 44 to wind, so that the winding wheel 44 forms spiral winding on the connected cable 1; or the sliding ring 49 is driven to slide by rotating the rocker 48 through threads, so that the winding wheel 44 forms spiral winding on the connected cable 1, and the winding effect is ensured.
