Abstract

The utility model discloses a torque energy-saving cable clamp, which comprises an upper clamp plate and a lower clamp plate which are provided with at least one mounting hole, the upper clamp plate and the lower clamp plate are screwed through a torque nut passing through the mounting hole, the torque nut automatically breaks when reaches a set torque, concave slots are oppositely arranged on buckling faces of the upper clamp plate and the lower lamp plate, and inner faces of the concave slots are provided with antiskid convex patterns. The torque energy-saving cable clamp is applied in connecting engineering of a steel stranded wire, an aluminum stranded wire or a steel core aluminum stranded wire in aerial electrical cables, the processing art is simple, the ventilation and the heat radiation are excellent, the torque energy-saving cable clamp has the characteristics of facilitating power transmission wire protection, saving material and reducing weight. By the adoption of the torque energy-saving cable clamp, manufacture cost of a cable clamp is greatly reduced, and the torque energy-saving cable clamp is suitable for wide wire diameter scope.

Description

The energy-conservation wire clamp of moment

Technical field

The utility model relates to a kind of wire clamp, relates in particular to the wire clamp of a kind of power line and ditch.

Background technology

Wire clamp complex manufacturing technology in existing, it clamps poor effect, be easy to generate to come off, and its manufacturing materials is more, and production cost is higher.

The utility model content

The purpose of the utility model is to solve the problems of the prior art, provides a kind of moment energy-conservation wire clamp.

The technical scheme of the utility model is: the energy-conservation wire clamp of a kind of moment; Comprise the train wheel bridge and the lower plate that offer at least one installing hole on it; Passing installing hole through torque nut between said train wheel bridge and the lower plate is spirally connected; The buckling surface of said train wheel bridge and lower plate is provided with the spill wire casing relatively, and the inner face of said spill wire casing is provided with anti-skidding burr.

Said installing hole comprises the circular port of offering on the bar hole offered on the train wheel bridge and the lower plate; Said torque nut adds backing plate and passes said bar hole and circular port with said train wheel bridge with lower plate is fastening joins, and torque nut ruptures when setting moment reaching automatically.

The outer rim of said train wheel bridge and lower plate is circular arc.

Anti-skidding burr in the said spill wire casing is vertical.

Anti-skidding burr in the said spill wire casing is horizontal.

The utility model is applicable to the engineering that continues of steel strand wire, aluminium stranded conductor or the steel reinforced aluminium conductor of overhead power line; Its processing technology is simple, ventilation and heat good; Help the protection of power transmission line; Have the advantages that to save material, weight reduction, the utility model greatly reduces the manufacturing cost of wire clamp, and it is wide to be suitable for wire range.

Embodiment

Understand for technological means, technical characterictic, utility model purpose and the technique effect that the utility model is realized is easy to understand,, further set forth the utility model below in conjunction with concrete diagram.

Extremely shown in Figure 4 like Fig. 1; The energy-conservation wire clamp of a kind of moment; Comprise the train wheel bridge 1 and lower plate 2 that offer bar hole 11 and circular port 21 on it; The non-buckling surface of train wheel bridge 1 and lower plate 2 is circular arc, and the screw rod 31 through torque nut 3 between train wheel bridge 1 and the lower plate 2 passes bar hole 11 and circular port 21 and rotary nut 32 and is spirally connected fasteningly, cooperates with screw rod 31 and joins as establishing interior tooth 321 in Fig. 6 nut 32; Adding backing plate 4 and packing ring like this torque nut 3 of Fig. 5 with train wheel bridge 1 joint, offering the circular hole 41 that matches with torque nut 3 external diameters on this backing plate 4, train wheel bridge 1 is butterfly after fastening with lower plate 2.

Buckling surface at train wheel bridge 1 and lower plate 2 is respectively arranged with train wheel bridge spill wire casing 12 and lower plate spill wire casing 22; And train wheel bridge spill wire casing 12 is oppositely arranged with lower plate spill wire casing 22; Its notch is semicircle; Inner face at train wheel bridge spill wire casing 12 and lower plate spill wire casing 22 is provided with the anti-skidding burr 5 with antiskid function, and this anti-skidding burr 5 is vertical or horizontal strip projected parts, also can be the convexity of point-like.

Train wheel bridge 1 in the utility model and lower plate 2 its length can according to the power line length that is continued with and step up condition such as degree and design; Can offer at least one bar hole 11 and at least one circular port 21 above that; Be one group promptly, many groups can be set according to the factors such as thickness of clamping force and power line with a bar hole 11 and a circular port 21.

The material of the utility model is an aluminium alloy, adopts casting or Forging Technology, has high-strength anti-corrosion erosion performance; The torque nut 3 that is adopted can give wire clamp with constant compression force; Torque nut 3 ruptures when setting moment reaching automatically, the vertical or horizontal anti-skidding burr of setting up on the spill wire casing inner face, increased conductive contact surfaces with and prevented the slippage of lead; Improve its electric conductivity greatly, and prevented the damage of lead.It is zinc-plated to use the utility model to carry out on the surface of train wheel bridge 1, lower plate 2, better transitional the conductance between copper conductor or the aluminum conductor.

Being merely the utility model preferred embodiment in sum, is not the practical range that is used for limiting the utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to the technological category of the utility model.
