Description
Technical field
The present invention relates to electric armour clamp technical field, more particularly to a kind of insulation puncture line clamping convenient for clamping, for exhausted
Edge cable branch or the quick connection of continued access circuit.
Background technology
Including upper casing and lower casing, piercing blade is fixed in the upper casing for insulation puncture line clamping of the prior art,
It is equipped with lower piercing blade in lower casing, the mating surface position of upper casing and lower casing is equipped between gasket, waterproof silicone grease, upper casing and lower casing
High-strength bolt and torque nut are equipped with, torque nut connect composition nut assembly with locking nut.When cable needs
When branch or continued access, main cables and breakout cable are clamped between the piercing blade of the upper lower casing of insulation puncture line clamping, penetrate height
Strength bolts, then twist the torque nut on wire clamp by box spanner, are compressed upper-lower casing by locking nut, herein mistake
Piercing blade meeting penetrating insulating layer of cable in journey contacts conducting, main cables and breakout cable conducting connection with conductor；When torque reaches
During to setting value, the connection between torque nut and main nut disconnects, and upper-lower casing is locked by locking nut, and torque nut takes off
It falls.The insulation puncture line clamping of such structure is to be fixedly connected between piercing blade and housing, the line of the wire clamp connection of same specification
Cable diameter range is small, and the torque error range that comes off of torque nut is big, it is specified that cable diameter and piercing blade in range
Contact dynamics it is different, it may appear that the problem of loose contact or piercing blade cut-out cable conductors.In addition, upper casing and lower casing use
The mode that bolt and nut clamps, at the scene during installation connection, by the both hands of an operator, should fixed cable, connect again
And clamping screw nut, operation difficulty is big, operator is required high.
