Embodiment 1
[0018] This embodiment is a kind of electric power wiring fittings, see Figure 1 to Figure 6 As shown, it includes a base 1 , two pressure rings 2 and two sets of pressure jaw assemblies 3 .
[0019] The base body 1 includes a base pipe part 11, a core pipe part 12 arranged in the lumen of the base pipe, and a connecting plate part 13 for connecting and fixing the base pipe part and the core pipe part; There is an internal thread area 111; the base pipe part and the core pipe part are arranged concentrically, and the connecting plate part is an annular plate located between the base pipe part and the core pipe part. In this embodiment, the connecting plate part is located between the base pipe part and the core pipe At the axial middle end of the pipe part, two internal thread areas are located on both sides of the connecting plate part; in practice, the structural shape of the connecting plate part only needs to meet the fixed connection between the base pipe part and the co...
Embodiment 2
[0034] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 6 to Figure 9 As shown, this embodiment also includes a mandrel 7 located in the lumen of the core tube part; four arc-shaped clamping grooves 71 are provided on the outer peripheral wall of the mandrel, each arc-shaped clamping groove extends axially along the core tube part, each The arc-shaped clamping grooves are arranged opposite to the arc-shaped grooves on the inner wall of the corresponding one of the pressure jaws; each arc-shaped clamping groove and a corresponding arc-shaped groove are clamped to form a clamping hole 4; so this embodiment can form four clamping holes, Can be used to clamp four cables simultaneously.
[0035] The outer peripheral wall of the mandrel is provided with four supporting positioning convex plates 72 protruding along the radial direction of the core tube part, and the inner peripheral wall of the core tube part is provided with four positioning slid...
Embodiment 3
[0037] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 10As shown, this embodiment also includes a voltage transformer 8; the voltage transformer includes a ring-shaped induction body 81 and an intelligent control module: in this embodiment, an annular groove is provided on the inner peripheral wall of the core tube, and the ring-shaped groove The opening is located on the inner peripheral wall at the axial middle end of the core tube, and the groove extends radially into the connecting plate; the ring-shaped induction body and the intelligent control module of the voltage transformer are fixed in the ring-shaped groove. In specific practice, the voltage transformer can also be fixedly arranged on other positions, as long as the clamping hole is located in the cavity of the ring-shaped induction body, that is, it is only necessary to make the cable pass through the cavity of the ring-shaped induction body .
[0038] The intelligent contro...
