Screw rod is fixed through the part lower nut of lower limb body; The surrounding of lower nut is wrapped by columniform lower nut shell, the sealing of below nut plug; Lower nut shell and lower limb body one-body molded;
The right side of upper limb body front portion is provided with a rubber seal cap; Rubber seal cap sleeve is located in rubber seal cap shell, is connected on upper limb body by rubber seal cap shell.
Totally six groups, blade, upper limb body and lower limb body all arrange three groups, and the blade that upper limb body and lower limb body are arranged is in symmetrical up and down.
Torque nut is arranged on the upper end of screw rod by viscose glue.
Blade is provided with three edges of a knife, the blade on upper limb body is M shape, and the blade on lower limb body is W shape.
The utility model adopts the torque nut design of two rank, and ground floor torque nut is screwed to after set moment twists into two parts, and also needs to twist into two parts second layer torque nut and arrives set moment, just can complete installation; Simultaneously for preventing the generation of high-voltage corona, entirety is closed, without exposed metal/bare metal; Therefore the utility model has good insulation property, and the highest cable line being applicable to 35KV uses.Further, blade of the present utility model has three edges of a knife, and symmetrical up and down, and while ensure that puncture effect, wire is not easy the pulling force because applying and comes off, and the electric conductivity of employing connection line of the present utility model is ensured reliably.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the right side view of Fig. 1.
In figure: 1, torque nut; 2, upper limb body; 3, lower limb body; 4, lower nut shell; 5, screw rod; 6, blade; 7, sealing rubber pad; 8, nut plug; 9, rubber seal cap; 10, sealing cap shell; 11, plain cushion.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises the upper limb body 2 and lower limb body 3 that are connected by screw rod 5, and wherein, screw rod 5 is two, and upper end is all provided with torque nut 1; Plain cushion 11 is provided with between torque nut 1 and upper limb body 2; Upper limb body 2 and lower limb body 3 are divided into front and rear by screw rod 5; The front portion of upper limb body 2, the lower surface at rear portion and the front portion of lower limb body 3, the upper surface at rear portion are provided with blade 6; Blade 6 is provided with sealing rubber pad 7 with the junction of upper and lower limbs; Sealing rubber pad 7 can be designed to arc, like this when electric lead is through after the utility model punctures, the position that the sealing rubber pad 7 of arc is fitted around wire is tightr, and insulation property are better.
Screw rod 5 is fixed through the part lower nut of lower limb body 3; The surrounding of lower nut adopts that the lower nut shell 4 be made up of cylindrical conductive substance wraps, below nut plug 8 seals; Lower nut shell 4 is one-body molded with lower limb body 3.Therefore can ensure that the utility model entirety is for what close, do not have exposed metal/bare metal outside, improve insulation property, make it go for higher voltage, most High Availabitity uses in the circuit of 35KV.
The right side of upper limb body 2 front portion is provided with a rubber seal cap 9; Rubber seal cap 9 is set in rubber seal cap shell 10, is connected on upper limb body 2 by rubber seal cap shell 10.Rubber seal cap 9 is designed to demountable structure, and can unload the situation of observing the inside wire and connecting at any time down, outside rubber seal cap shell 10 carries out insulation protection.Upper limb body 2 of the present utility model, lower limb body 3, nut plug 8 and rubber seal cap shell 10 all adopt the good insulating material of insulation property to make, and ensure overall good insulation properties.
