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.

[0021] See also Figure 1 and Figure 2 A power conductor connection fitting may include a conductor connection protection part 10, at least one set of support and fixing parts 20, and two sections of heat shrink tubes 30. The conductor connection protection part 10 may be used to protect the winding connection part of two conductors; the heat shrink tube 30 may protect the part where the conductors are inserted into the conductor connection protection part 10; and the support and fixing part 20 may be used to assist the power conductor connection fitting to be fixed at the placement position.

[0022] In this embodiment, the wire connection protection part 10 includes a wire insertion tube 11 and a cap 12. The wire insertion tube 11 has three openings: two coaxially distributed openings in the wire insertion tube 11 are used to insert the wires; and another opening in the wire insertion tube 11 is used to complete the winding connection operation of two wires. Two sections of heat shrink tubes 30 are respectively fixed at the two coaxially distributed openings of the wire insertion tube 11, so that the wire can pass through the heat shrink tube 30 when inserted into the wire insertion tube 11. After the heat shrink tube 30 is deformed by heat, it can be coated on the outside of the wire and cover the gap between the corresponding opening of the wire insertion tube 11 and the outer skin of the wire. The cap 12 is detachably covered at the opening used to complete the winding connection operation of the two wires, and the cap 12 can cover the corresponding opening of the wire insertion tube 11 after the wires are wound and connected. The support and fixing part 20 is sleeved on the outside of the wire insertion tube 11 in the wire connection protection part 10, and a fixing hole for fixing the power wire connection hardware is formed on the support and fixing part 20. Fasteners such as bolts can be used to pass through the support and fixing part 20 to fix the device at a desired position.

[0023] See also Figure 4, the wire insertion tube 11 includes a transverse tube 111, a vertical tube 112, a baffle plate 113 and two insertion holes 114. The vertical tube 112 is formed in the middle of the transverse tube 111 and communicates with the inner cavity of the transverse tube 111. The openings at both ends of the transverse tube 111 are used to insert the wires respectively, and the top opening of the vertical tube 112 is used for winding and connecting the two wires. The baffle plate 113 is formed inside the vertical tube 112, and the two insertion holes 114 are formed on the baffle plate 113. The two wires inserted into the transverse tube 111 can pass through the two insertion holes 114 respectively and be wound and connected above the baffle plate 113. When connecting the two wires, the internal conductive core is stripped out of a certain length in advance, and the conductive core passes through the transverse tube 111, the vertical tube 112 and the insertion holes 114 on the baffle plate 113, so that the conductive cores of the two wires can be protruded above the baffle plate 113. Then, the conductive inner cores of the two wires are twisted together on the blocking plate 113 .

[0024] In this embodiment, the top of the outer wall of the vertical tube 112 and the inner wall of the cover cap 12 are formed with mutually matching thread structures, so that the cover cap 12 can be screwed and fixed from the top of the vertical tube 112 or loosened and removed.

[0025] See also Figure 3 The support and fixing part 20 may include a sleeve section 21, an upper support plate 22, a lower support plate 23, a support tube 24 and an elastic pad 25. The sleeve section 21 is sleeved on the outer side of the transverse tube 111 and fixedly connected thereto, the upper support plate 22 and the lower support plate 23 are respectively formed at the top and the bottom of the sleeve section 21, and the upper support plate 22 and the lower support plate 23 are both formed with longitudinally aligned fixing holes, so that the user can use the locking piece to pass through the upper support plate 22 and the lower support plate 23 to complete the limited fixing of the support and fixing part 20 and the wire connection protection part 10. The support tube 24 is arranged between the upper support plate 22 and the lower support plate 23, and the support tube 24 passes through the fixing holes on the upper support plate 22 and the lower support plate 23. The two ends of the support tube 24 are respectively fixedly connected to the upper support plate 22 and the lower support plate 23, so that the support tube 24 can improve the overall mechanical strength of the support fixing part 20 and reduce its stress damage; in addition, the locking piece passing through can be shielded to reduce the rust of the locking piece. The elastic pad 25 is detachably inserted and arranged between the upper support plate 22 and the sleeve section 21, and the support tube 24 passes through the elastic pad 25. The elastic pad 25 can support and buffer when the upper support plate 22 is deformed by external force, reducing the stress deformation of the sleeve section 21 and the wire insertion tube 11.
