Abstract
The utility model discloses a lead connecting device which is characterized by comprising a screw, and a back-up ring I, a back-up ring II, a back-up ring III, a nut I and a nut II which are arranged on the screw, wherein the nut I and the nut II are respectively arranged the two ends of the screw. The lead connecting device has the advantages of low cost, convenient part processing, convenient to carry, simple installation, large contact area of crimping, and firm crimping; and can avoid swinging and heating, which is safe and reliable.
Description
Technical field
The utility model belongs to overhead transmission line power supply technique field, relates in particular to the wire connection device of transmission line.
Background technology
At present, in transmission line, between wire and wire, between wire and cable, between cable and cable, connecting is all to carry out the bolt crimping by device clamp or copper cash nose, and this kind bolt crimping contact area is little, crimping is not firm, easily swing, fever phenomenon easily occurs, affect the safe operation of equipment.This is the deficiencies in the prior art parts.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, and a kind of simple and practical wire connection device is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: wire connection device, it is characterized in that: described wire connection device is comprised of screw rod, the back-up ring I, back-up ring II, back-up ring III, nut I, the nut II that are arranged on described screw rod, and described nut I, nut II are arranged on the two ends of described screw rod.By adjusting nut I, nut II screw thread, wire is played to fixation.
Further improvement of the utility model has, and described back-up ring I, back-up ring II, back-up ring III and described screw rod are slidably connected.
Further improvement of the utility model has, and two end faces of described back-up ring III are provided with at least two concentrically ringed decorative patterns.The purpose that decorative pattern is set at back-up ring III end face is the frictional force that increases between back-up ring III and wire, makes wire connect more firm.
The beneficial effect of this programme can be learnt according to the narration to such scheme, wire connection device, it is characterized in that: described wire connection device is comprised of screw rod, the back-up ring I, back-up ring II, back-up ring III, nut I, the nut II that are arranged on described screw rod, and described nut I, nut II are arranged on the two ends of described screw rod.The beneficial effects of the utility model are: cost is low, and part is convenient to processing, and is easy to carry, installs simply, and the contact area of crimping is large, and crimping is firm, can avoid swinging the appearance with fever phenomenon, and is safe and reliable.
