[0091] The first connecting position 700 is connected with the first to-be-connected part through the fourth connecting hole 710 arranged on the first connecting position 700. Specifically, a plurality of fourth connecting holes 710 are arranged on the first connecting position 700 in the second direction Y. The fourth connecting hole 710 is arranged with an abutting column 720 in the first direction X. The two ends of the abutting column 720 in the first direction X are connected with the side walls on both sides of the first connecting hole 321 in the third direction Z, so as to divide the fourth connecting hole 710 into a first sub-hole 711 and a second sub-hole 712. When the first to-be-connected part is placed on the support frame 40, the first main plate is located in the first sub-hole 711, the second main plate is located in the second sub-hole 712, and the abutting column 720 abuts against the first limiting groove.

[0092] Further, the support frame 40 of the present application further comprises a first abutting buckle 730, which is located on one side of the fourth connecting hole 710.

The abutting surface is arranged from outside to inside in a slope manner, and the abutting surface is arranged in the second connecting position 800. When the second to-be-connected part 30 is installed on the second connecting position 800, the second to-be-connected part 30 contacts with the abutting surface of the second abutting buckle 810, and drives the second abutting buckle 810 to move outward until the second to-be-connected part 30 is buckled on the bottom of the second abutting buckle 810.

[0096] Please refer to the accompanying drawings Figure 1 to the drawings Figure 5 The specific installation process and disassembly process of each part in the wiring assembly of the present application are as follows.

[0097] Firstly, the first to-be-connected piece 20 is placed on the first connecting position 700 on the support frame 40, and the first abutting buckle 730 is driven to move, then the first to-be-connected piece 20 is moved to the bottom of the first abutting buckle 730, at this time, the first abutting buckle 730 is buckled above the first to-be-connected piece 20 and limits the upward movement of the first to-be-connected piece 20, at this time, the first limiting groove 510 on the first to-be-connected piece 20 abuts against the abutting column 720 to limit the downward movement of the first to-be-connected piece 20, and the limiting of the first to-be-connected piece 20 in other directions is realized by the sidewall on the first connecting position 700, so as to finally realize the limiting of the first to-be-connected piece 20 in each direction. When disassembling, the first abutting buckle 730 is driven to move by external force, so as to cancel the limiting of the first abutting buckle 730 to the first to-be-connected piece 20, so as to facilitate the removal of the first to-be-connected piece 20 from the first connecting position 700.

[0098] Then, the second to-be-connected piece 30 is placed on the second connecting position 800 on the support frame 40, the second to-be-connected piece 30 abuts against the abutting surface on the second abutting buckle 810, and the second abutting buckle 810 is driven to move until the second abutting buckle 810 is avoided relative to the second to-be-connected piece 30, the second to-be-connected piece 30 is moved to the bottom of the second abutting buckle 810 to realize the limiting of the second abutting buckle 810 to the second to-be-connected piece 30 in the first direction X and the second direction Y, and the limiting of the second to-be-connected piece 30 in other directions is realized by the sidewall on the second connecting position 800, finally realizing the limiting of the second to-be-connected piece 30 in each direction. When disassembling, the second abutting buckle 810 is driven to move by external force, so as to cancel the limiting of the second abutting buckle 810 to the second to-be-connected piece 30, so as to facilitate the removal of the second to-be-connected piece 30 from the second connecting position 800.

[0099] Finally, the first connecting part 400 of the connecting piece 10 is inserted into the second connecting hole 550, the second elastic plate 420 of the first connecting part 400 abuts against the first side wall 551 of the second connecting hole 550, the second elastic plate 420 moves close to the first elastic plate 410, under the action of external force, the first connecting part 400 moves downward until the limiting protrusion 430 moves to the bottom of the first to-be-connected piece 20, at this time, the limiting protrusion 430 abuts against the first to-be-connected piece 20, and the first limiting groove 510 abuts against the abutting column 720, so as to realize the detachable connection between the connecting piece 10 and the first to-be-connected piece 20. At the same time, the connecting terminal 320 enters the third connecting hole 610 in the second to-be-connected piece 30, under the extrusion of the third connecting hole 610, the first deformation part 322 and the second deformation part 323 move close to the first connecting hole 321, and are connected in a deformed manner after being inserted between the third connecting hole 610. When disassembling, the second elastic plate 420 needs to be driven to move close to the first elastic plate 410 by external force, so as to facilitate the first connecting part 400 to be directly removed from the second connecting hole 550. Further, the disassembly between the connecting terminal 320 and the third connecting hole 610 can be directly pulled out from the third connecting hole 610 by external force.
