Abstract
The utility model belongs to a connection device used for connecting wires in electric power distribution and transmission lines, particularly relating to structural improvement. A cam-type C-shaped wire-clip provided with a C-shaped wire-clip seat is characterized in that the C-shaped wire-clip seat has elasticity, combined cam press wire blocks 2 are arranged in the C-shaped wire-clip seat, the surfaces of the cams of two cam press wire blocks contact with each other, the upper and the lower surfaces of the cams are parallel surfaces, or an included angle smaller than 30 DEG is formed between the upper and the lower surfaces; circular arc surfaces smaller than 180 DEG are formed at the opposite of the cam surfaces; the circular arc surfaces at two sides of the cam press wire blocks of the combined cams and the circular arc surfaces at two sides of the c-shaped wire-clip seat form a circle smaller than a whole circle after butt joint, and cog grains 5 are arranged in the circular arc surfaces at two sides of the C-shaped wire-clip seat. The utility model can reduce the procedure and cost of producing process. The cog grains are densely arranged in the C-shaped wire-clip seat of the wire-clip and the circular arc wire slots of the press wire blocks of the combined cams, oxidizing layer can be punctured when conducting wires are connected, and thus the conducting wires can be clipped tightly. Contact resistance is small, and connection effect is favorable.
Description
Technical field
The utility model belongs in a kind of power distribution, the transmission line a kind of jockey that connects lead, particularly to the improvement of its structure.
Background technology
More approaching like product is " a hinge type C shape wire clamp ", and its structure is, compact heap is to adopt hinged mode, utilizes bolt pressing compact heap that lead is continued, the structure relative complex, and production cost is higher relatively, and the twisting place is walked or slippage; And wire casing do not have groove, is difficult for puncturing oxide layer, and contact resistance is big relatively during use.
Summary of the invention
The purpose of this utility model is, overcomes the shortcoming that above-mentioned prior art exists, and a kind of improved cam-type C shape wire clamp is provided.Structure of the present utility model is, cam-type C shape wire clamp, have C type tension seat 1, it is characterized in that, C type tension seat has elasticity, and the cam surface that has 2, two cam line balls of conjuncted cam line ball piece piece in C type tension seat contacts, top and bottom are parallel surface, or top and bottom become the angle less than 30 degree; The opposite of cam surface becomes the arc surface less than 180 degree; The arc surface of conjuncted cam line ball piece 2 both sides and C type tension seat both sides arc surface are installed the circle of back formation less than full circle.
For safe and reliable, have groove 5 in the both sides arc surface of C type tension seat.
Its structure also can, conjuncted cam line ball piece 2 has centre bore 8, C type tension seat is installed with cup head bolt 3 also corresponding having in center oblong aperture 9, two centre bores, by nut 4 and spacers.
The utility model adopts conjuncted cam line ball block structure, can make production and cam line ball piece is installed to become more convenient.During installation, lead is placed in the wire casing of C type tension seat both sides, the more conjuncted cam line ball piece of ∧ type is put into C type tension seat; Utilize the mobile off normal (the arc groove central moment of wire casing is little before installing) of cam, press conjuncted cam line ball piece by ambient pressure or cup head bolt, the conjuncted cam that makes the ∧ type stretches for middle mind-set both sides with junction 6, up near level, thereby compresses lead and reaches the effect that continues.This mode reduces the technological process of production and cost.Densely covered groove can puncture oxide layer, thereby more can firmly bite lead in the circular arc wire casing of the c shape tension seat of wire clamp and conjuncted cam line ball piece when continuing lead, and contact resistance is littler, and better effects if continues.
C clamp line seat of the present utility model has spring function, tension force that when installing, produces or the heat that when circuit fortune is drawn and stopped, taking place open that shrinkage can be received synchronously or, to keep the constant pressure that continues; Be installed in the conjuncted cam line ball piece in the C clamp line seat, when the cup head bolt is tightened, can produce very big side-thrust, under the thrust that the elasticity of C clamp line seat keeps, wire clamp and lead are continued together safely and reliably again.Reached the power circuit effect that continues.
Structurally compared with the prior art this product has particular structure.Because thereby the simplification of structure and production procedure reduces cost, user installation is easy, uses common tool just can install, for the requirement of power circuit " non-maintaining, exemption from inspection " has improved a step.
The critical piece of the utility model except that the bolt pad of fastening usefulness, the aluminum alloy materials production of the desired high conductivity high strength of using for power circuit of wire clamp, adopt the higher section bar processing mode of simple production rate of production technology, more can guarantee material, density and dimensional accuracy.

1 conjuncted C type tension seat, 2 conjuncted cam line ball pieces, 3 cup head bolts, 4 nuts, 5 grooves, 6 junctions, the conjuncted cam of 7 ∧ types, 8 holes, 9 oblong aperture.
Embodiment
Cam-type C shape wire clamp has C type tension seat 1, and its structure is, C type tension seat has elasticity, and the cam surface that has 2, two cam line balls of conjuncted cam line ball piece piece in C type tension seat contacts, and top and bottom are parallel surface, or top and bottom become the angles less than 30 degree; The opposite of cam surface becomes the arc surface less than 180 degree; Become less than full circle after the butt joint of the arc surface of conjuncted cam line ball piece 2 both sides and C type tension seat both sides arc surface.Have groove 5 in the both sides arc surface of C type tension seat.Conjuncted cam line ball piece 2 has centre bore 8, and C type tension seat is installed with cup head bolt 3 also corresponding having in center oblong aperture 9, two centre bores, and is fixing by nut 4.
