Abstract

The utility model discloses a wedge-shaped line clamp, and is characterized in that a C-shaped basal body is provided with a load-carrying base, a bolt guiding hole is arranged in the load-carrying base, and a screwed hole is arranged at the corresponding position of a wedge block and the continuous mounting of wedge blocks is fast in speed. The utility model has the advantages of no need of specialized tools, simple operation, small continuous resistance, extremely stable electro-oxidation performance, non-heating effect, good continuous quality, low cost, and high safety factor, and can be detached and repeatedly used. The utility model can be widely applicable to the mutual connection among aluminium hinge wires, steel-cored aluminium hinge wires, copper hinge wires, or copper wires.

Description

A kind of wedge clamp

Technical field:

The utility model relates to a kind of connector that is used for the high-low voltage transmission-distribution line road and is commonly called as line, specifically a kind of wedge clamp.

Background technology:

Domestic a large amount of uses at present be the parallel groove clamp of " bolt lock type ", this kind wire clamp is finished being connected of lead and lead by the pressure of the two or more pairs of ditch aluminium flakes and nut clamping screw, the contact area of wire clamp and lead is little, contact resistance is bigger, electricity oxygen unstable properties, so every place lead is connected with lead, need to use at least two " parallel groove clamp ", and the failure rate height; H type aluminium jointing clamp is now also promoted at home, and its shortcoming is non-dismountable, and needs to use hydraulic crimping tool; In addition, U.S.'s wedge clamp that use in domestic part city, though connecting quality is good, but this wedge clamp is U.S.'s specification, different because of the steel core wire that uses with domestic diameter, cause the steel-aluminium conductor diameter difference of same nominal area, can not be fit to the continuing of metric system aluminum conductor of domestic use fully, because U.S. rule wedge clamp needs special-purpose instrument (launching rifle) and operation sequence numerous and diverse when operation is installed, operation is very inconvenient when using in the high-altitude; Launching rifle not only costs an arm and a leg, and need the special-purpose core that launches, launching core is expendable consumed product, and the use cost height needs specific purpose tool and complicated operation, so can't popularize, U.S. in addition rule wedge clamp in use owing to be to insert in the C shape matrix by Pneumatic immpacting power, there is no the special insurance measure, along with the variation of environment for use, easily produce and become flexible, cause the fault of using the back that power circuit takes place.

Summary of the invention:

The purpose of this utility model is to provide a kind of improved wedge clamp, and it can overcome some shortcomings of the prior art.

To achieve these goals, the technical solution of the utility model is: a kind of wedge clamp, it mainly comprises C shape matrix and can be seated in the interior voussoir of C shape matrix, it is characterized in that: be provided with bearing base at C shape matrix, in bearing base, be provided with the bolt guide hole, be provided with screwed hole in the relevant position of voussoir.

The utility model compared with prior art has following characteristics:

Owing to be provided with bearing base at the small end place of C shape matrix, in bearing base, be provided with the bolt guide hole, relevant position at voussoir is provided with screwed hole, by the bolt guide hole on the bearing base, bolt is linked to each other with screwed hole on the voussoir, and by tightening bolt, it is up to drive voussoir, thereby realizes being connected between lead and the wire clamp;

2, on voussoir, be provided with the semicircle duct, be provided with the semicircle duct, can satisfy the various diameter requirements of domestic metric system lead, and can fill up the space of duct, make lead and the wire clamp can driving fit, improved the performance that continues at the inwall of C shape matrix;

3, owing to be by tightening bolt, it is up and compress lead to drive voussoir, need not expensive specific purpose tool, only needs common torque spanner to get final product.When dismounting, by stripping attachment counter-rotating bolt, voussoir can be ejected C shape matrix, saved use cost and equipment cost greatly;

4, this wire clamp is owing to be to drive the voussoir upstream or downstream by rotating bolt, so voussoir is after being in place, bolt still keeps constant torsion that voussoir is fixed, can guarantee that whole wire clamp is connected firmly, can not become flexible, can improve pulling force, resistance and temperature rise level, meet the international standard level fully;

5, the voussoir installation rate that continues is fast, need not specific purpose tool, and simple to operate, adapting electric voltage is little, and electric oxygen performance is extremely stable, does not generate heat, and it is best in quality to continue, and cost is low, and detachable, reusable, safety factor is higher;

6, can be widely used in interconnecting between aluminium hinge line, steel core aluminium hinge line, copper hinge line or the copper cash.

Embodiment:

Below in conjunction with drawings and Examples the utility model is further described.

The utility model mainly comprises C shape matrix 4 and the voussoir 8 that can be seated in the C shape matrix 4, it is different from prior art and is: be provided with bearing base 1 at C shape matrix 4, in bearing base 1, be provided with bolt guide hole 2, the nut guide hole of being located at bearing base is generally circle or rectangle, be provided with screwed hole 9 in the relevant position of voussoir 8, be provided with bearing base at the small end place of C shape matrix in the enforcement, inwall at C shape matrix is provided with semicircle duct 3, on voussoir 8, be provided with semicircle duct 6 and spill chute 5, the screwed hole 9 of voussoir is positioned at the bottom of spill chute 5, the centre that the spill chute of voussoir is positioned at voussoir is a rectangle, its opening is parallel with the voussoir outer face, present embodiment is provided with circular arc salient angle 10 at the place, outer end of the semicircle duct of voussoir 8 both sides, the circular arc salient angle of the semicircle duct of the semicircle duct of C shape matrix inwall and voussoir both sides driving fit fully during use, tight produces, carrying out lead when continuing, the nut that passes the nut guide hole is screwed into the screwed hole that is positioned at spill chute bottom on the voussoir, and it is up to drive voussoir.
