Description
Technical field
The utility model relates to a kind of non-bearing type that is used for electrical power trans mission/distribution system and connects gold utensil, specifically is the jockey of power transmission and distribution plain conductor.
Background technology
Connection between the connection of existing power transmission and distribution plain conductor, particularly aluminium stranded conductor or the steel reinforced aluminium conductor, aluminium stranded conductor and copper stranded conductor be connected and copper stranded conductor between connection, the screw bolt-type wedge type clamp of employing is by shown in the left view of the front view of Fig. 3 and Fig. 4.The inside of C shape shell 11 is shaped on two planes 13 and 16 that face openend 18 and arrange along the length direction S ladder of opening, and an end on thicker plane 13 is shaped on the through hole parallel with the openend length direction 17; One wedge core 14 is embedded in the inside of C shape shell, the interior shape of the upper and lower end face of wedge core and C shape shell adapts so that it can slide along the length direction of openend, a thicker end is shaped on the screw parallel with openend 15, this screw and aforementioned through-hole coaxial line, a bolt 12 passes through hole and screws in described screw; The two ends of wedge core are shaped on 19, two cylinder cambered surfaces of cylinder cambered surface respectively and form certain angle (about 5 degree), and the interior cylinder cambered surface 20 of this cylinder cambered surface and C shape enclosure both sides forms the wedge mouth of mobilizable clamping plain conductor.During use, two plain conductors place respectively in the wedge mouth, and rotating bolt 12 spurs wedge cores 14 then, thereby clamp plain conductor.The elastic reaction that this C type shell is had, stress relaxation that can compensating wire makes wire clamp all form organic whole with lead in any environment.
Though the wire clamp of this kind structure can use effectively, but, comparatively require great effort because of having the bigger moment of resistance (useless moment) during use, and the profile of C shape shell is bigger because the plane P that two wedge mouths of bolt shaft linear distance axis is become is far away, quality is bigger, and cost is difficult to further reduction.This wire clamp does not have locking device in addition, and the safety guarantee performance waits to improve.
Summary of the invention
The purpose of this utility model provides a kind of improvement of screw bolt-type wedge type clamp, and this wire clamp should be able to overcome the deficiency of above-mentioned background technology, have rational in infrastructure, easy to use laborsaving, weight is lighter, lower-cost characteristics.
The technical scheme that the utility model proposes is:
Screw bolt-type wedge type elastic force wire clamp, comprise C shape shell and be embedded in the interior wedge core of C shape shell, C shape enclosure faces openend and is shaped on two planes arranging along the length direction ladder of opening, one end on thicker plane is shaped on the through hole parallel with the openend length direction, the interior shape of the upper and lower end face of wedge core and C shape shell adapts so that it can slide along the length direction of openend, a thicker end is shaped on the screw parallel with openend, this screw and aforementioned through-hole coaxial line, a bolt passes through hole and screws in described screw; The two ends, the left and right sides of wedge core are shaped on the cylinder cambered surface of mutual formation certain angle respectively, the interior cylinder cambered surface of these two cylinder cambered surfaces and C shape enclosure both sides forms the wedge mouth of mobilizable clamping plain conductor respectively, one of the position formation that described C shape enclosure is shaped on screw faces projecting upwards of openend, and the corresponding concave surface that makes progress is made at the position with this cylinder cambered surface corresponding section of wedge core.
The outside wall surface that projects upwards of described C shape shell is a cylinder cambered surface.
The concave surface with this cylinder cambered surface corresponding section of described wedge core is the corresponding interior cylinder cambered surface that makes progress.
Described screw is furnished with packing ring.
Because the position that described C shape enclosure is shaped on screw faces openend to top offset, and the corresponding fovea superior in the position of the corresponding section of described wedge core, this just makes the distance of the plane P that the bolt axis is become with two wedge mouth axis shorten dramatically, make structure more reasonable, during use since the moment of resistance significantly reduce thereby obviously easily laborsaving, operate very simply, greatly reduce construction labour intensity; Also therefore reduce the thickness of C shape shell in addition, saved raw material, reduced consumption.After increasing the stainless steel spring packing ring in addition, also prevent bolt looseness effectively, guaranteed the safe and reliable of circuit, improved the running quality of whole circuit.

Embodiment
As shown in the figure, screw bolt-type wedge type elastic force wire clamp, comprise C shape shell 1 and be embedded in the interior wedge core 4 of C shape shell, C shape enclosure is shaped on two plane 1-2 and the 1-4 that faces openend 8 and arrange along the length direction S ladder of opening, one end on thicker plane is shaped on the through hole 1-3 parallel with the openend length direction, the interior shape of the upper and lower end face of wedge core 4 and C shape shell adapts so that it can slide along the length direction S of openend, a thicker end is shaped on the screw 4-2 parallel with openend, this screw and aforementioned through-hole coaxial line, a bolt 2 passes through hole and screws in described screw; The two ends, the left and right sides of wedge core are shaped on mutual formation certain angle cylinder cambered surface 4-1 respectively, two cylinder cambered surface 1-1 of these two cylinder cambered surfaces and C shape enclosure both sides form the wedge mouth of mobilizable clamping plain conductor respectively, because two cylinder cambered surface 4-1 form certain angle (about about 5 degree, thereby tighten at bolt that the wedge mouth diminishes gradually in the process of pulling wedge core, and then the chucking power of the plain conductor in the wedge mouth become greatly gradually, reached the purpose of firm grip plain conductor.The position that described C shape enclosure is shaped on through hole forms the 1-5 that projects upwards that faces openend, and move on the screw respective parallel of wedge core, plane 1-2 (except that the intermediate throughholes position) moves down in other words, makes the ladder margin of two parallel plane 1-2 and 1-4 reduce; In addition the wedge core make the corresponding concave surface 4-3 that makes progress with this position that projects upwards the 1-5 corresponding section, it is about 1/2nd that the distance of the plane P that two wedge mouths of bolt shaft linear distance axis become is shortened, so that the moment of resistance is obviously reduced.In addition, this change also can make the remarkable attenuate of thickness at C shape outer casing through hole place, thereby has alleviated weight, has saved raw material.
For improving the quality, the outside wall surface that projects upwards 1-5 of the screw hole parts of described C shape shell is made the cylinder cambered surface, and the concave surface 4-3 with this cylinder cambered surface corresponding section of described wedge core makes the corresponding interior cylinder cambered surface that makes progress.
For improving coefficient of safety, described screw is furnished with packing ring 3, generally can adopt the stainless steel spring packing ring, can prevent bolt looseness effectively, guarantees the safe and reliable of circuit.
