Description
Technical field
The utility model relates to a kind of connecting clamp of electrical lead, is applied to the connection that do not stress of electrical lead, and the strain insulator that is specially adapted to transmission line, distribution line, low-voltage circuit is crossed and drawn wire jumper and connect, and electric substation, factory's electricity distribution power lead connect.
Background technology
Now, the connection that do not stress of power circuit and electric substation, factory's distribution, the parallel groove clamp contact resistance that generally uses is big, galvanic corrosion is hindered soon, and burn, broken string accident are many, have potential safety hazard.But the strain insulator of transmission line, distribution line, low-voltage circuit is crossed and is drawn wire jumper and connect, and electric substation, factory's distribution do not stress connect many especially again; Now parallel groove clamp be electricity do not stress the weak link that connects, be hidden danger, but its cost is low, installing/dismounting is convenient, but still in a large amount of uses; Though; A kind of open-close type stress wire clamp has also appearred recently, still, this wire clamp exist buckling component many, fasten the low deficiency of precision.
Summary of the invention
The purpose of the utility model is to overcome the prior art deficiency; Provide that a kind of use cost is low, buckling component is few, fasten the precision height, good connecting effect, operation be easy, the electrical lead composite type stress wire clamp that can effectively reduce the wire clamp contact resistance, eliminates safe hidden trouble.
The purpose of the utility model can realize through following technical scheme:
Electrical lead composite type stress wire clamp, symmetrically arranged fastening positioning boss, the securing member formed from belt washer, by nut and bolt are formed up and down by reach the standard grade clamp and the clamp that rolls off the production line of the clamp of reaching the standard grade, the clamp that rolls off the production line, composite type line of tension clamp.Its reach the standard grade clamp and clamp the semicircular wire clamp body that rolls off the production line for two " C " word shapes fastening up and down; Be provided with swallow-tailed vertical fin in the inboard on the clamp right side of reaching the standard grade; Arranged outside in the clamp left side of reaching the standard grade has swallow-tailed vertical dovetail groove; Inboard in the clamp left side of rolling off the production line is provided with the swallow-tailed vertical fin that is complementary with dovetail groove; Arranged outside on the clamp right side of rolling off the production line has the dovetail groove that is complementary with vertical fin, snaps together behind the dovetail groove plug-in mounting that reach the standard grade clamp and the clamp that rolls off the production line are complementary through swallow-tailed vertical fin with swallow-tailed vertical fin to be flat " O " font.
The purpose of the utility model can also realize through following technical scheme:
Cooperating between the described swallow-tailed vertical fin of the utility model and the dovetail groove is matched in clearance, or cooperating between swallow-tailed vertical fin and the dovetail groove is interference fit.
The utility model reach the standard grade the fastening positioning boss at clamp bolt mounting hole place be provided with endoporus center line and bolt mounting hole central lines and with fastening positioning boss be one annular from belt washer.
Design principle of the utility model and use method of operation are following:
The key of the utility model is the semicircle oblate spool of composite type of boss of band, and oblate penetration pipe is to be formed by two flat " C " shape part make-ups, leans on concavo-convex dovetail groove to be locked into oblate penetration pipe to two flat " C " shape parts engagements to buckle.(be meant on the flat horizontal surface at top separately of the reach the standard grade clamp and the clamp that rolls off the production line) on two flat horizontal surfaces of oblate spool to have the semicircle boss that falls respectively that this semicircle is fallen the cross section of boss and is trapezoidal or circular or oblate or oval or fan-shaped or polygon semicircle or that stand upside down.Establish 2-6 bolt mounting hole in the semicircle centre of falling the boss of oblate spool (vertically on the symmetrical center line), in the bolt mounting hole, wear the afterburning clamping of bolt.Clamping force makes two leads squeezed separation; And be with the semicircle oblate spool of boss (after the reach the standard grade clamp and the clamp plug-in mounting combination of rolling off the production line) up and down respectively when changing to the figure of eight from flat " O " shape; Oblate spool produces the power of two leads that furthers again, thereby wraps two leads.It is that a kind of stress that utilizes connects, the electrical lead connecting clamp of safe and reliable, good connecting effect.The semicircle oblate spool of composite type of boss of band.Wire clamp adopts aluminium or the copper the most close with lead material, and bolt is a standard component.The composite type stress wire clamp that connects electrical lead uses the most close material with lead; Basically do not produce galvanic corrosion and hinder, stress is wrapped, and it is little to connect resistance; Attachment security is reliable; The strain insulator that can not only be used for transmission line, distribution line, low-voltage circuit is crossed and is drawn wire jumper and connect, and can also be used for power circuit branch or lead-in wire " T " connects, and has simultaneously that the aluminium of saving or copper material, cost are low, installing/dismounting operation characteristics easily.
The utility model compared with prior art have buckling component few, fasten that precision is high, safe and reliable, good connecting effect, saving aluminium or copper material, cost are low, installing/dismounting operation advantage easily.
