Abstract
The utility model relates to a disconnection prevention connector, especially relates to a disconnection prevention connector special for butt-joint of crosslinkage plastic extrusion conductor. The plastic extrusion disconnection prevention connector comprises a copper bush at the butt-joint point of the two conductors, characterized in that a triangular tooth type thread is set in the copper bush bore and the inner diameter of the copper bush is larger than the diameter of the conductor. The disconnection prevention connector has features of large friction force, high tensile strength, difficulty of disconnection after butt-joint of conductor, low production cost and convenient operation.
Description
Technical field
The utility model relates to a kind of anticreep connector, especially relates to a kind of crosslinked extrusion molding conductor butt joint anticreep connector that is exclusively used in.
Background technology
As everyone knows, when China many cables manufacturer produces crosslinked cable at present, carry out cross linked insulation after conductor is stranded when extruding, when a dish conductor was intact with extrusion molding, the end that needs coil conductor docked to keep continuous production with the head end that another coils conductor.The method of butt joint is: the smooth copper sheathing of endoporus of selecting one section certain-length for use, two sections conductors handling are inserted in the copper sheathing, compress on the external diameter of copper sheathing with hydraulic press then and (special-purpose jig is arranged on the hydraulic press, select for use according to conductor sizes), compress back emery wheel reconditioning copper sheathing external diameter.The conductor butt joint before coiling on going out cooling water pipe through extrusion molding cuts out joint.
The main deficiency of this kind structure is: conductor joint tensile strength is not enough, and particularly heavy in section conductor makes conductor slippage from copper sheathing disconnect when extrusion molding draws easily, and production can not be produced continuously, shut down start again after the processing, loses bigger.The crosslinked cable of general 35kV disconnects the back reopening and will lose about 50,000 yuan, mainly is scrap wire, binder removal, startup-shutdown scrap wire, personnel's wage, charges for water and electricity etc.
Summary of the invention
The technical problem that the utility model mainly is a little less than, the tensile strength little at existing in prior technology frictional force, pull easily after the conductor butt joint, production cost is high provides that a kind of frictional force is big, tensile strength is high, is difficult for after the conductor butt joint pulling, the extrusion molding conductor anticreep connector of low production cost.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of extrusion molding conductor anticreep connector, comprise the copper sheathing that is arranged on two sections conductor joints, it is characterized in that described copper sheathing endoporus is provided with triangle flute profile screw thread, the internal diameter of described copper sheathing is greater than the diameter of conductor.Docking calculation: select for use about a segment length 60mm, wall thickness 3mm, endoporus is a triangle flute profile screw thread, tooth depth 1.5mm, pitch 1.5mm, the screwed hole internal diameter is than the copper sheathing of the big 0.05～0.1mm of conductor nominal diameter, the copper sheathing material is a red copper, the conductor end face that will dock saw is neat, respectively fills in about copper sheathing 30mm, if be difficult to fill in available file outer through place under repair to conductor, compress on the external diameter of copper sheathing with hydraulic press then, pressure is 80Mpa, and special-purpose jig is arranged on the hydraulic press, selects for use according to conductor sizes, compress back emery wheel reconditioning copper sheathing external diameter, guarantee that external diameter herein is less than the diameter of conductor, to guarantee joint safety smoothly by core rod, the conductor butt joint before coiling on going out cooling water pipe through extrusion molding cuts out joint.The original smooth copper sheathing of endoporus that adopts connects during the conductor butt joint, because endoporus is smooth, coefficient of friction is little, the phenomenon that has slippage to disconnect after the conductor butt joint takes place, and tracing it to its cause is that inner hole friction force is not enough, and endoporus adopts the triangular form screwed hole now, through making the surface of thread embedded conductor after compressing, it has increased skin-friction coefficient, and the stretching resistance of conductor joint is improved, and reaches anti-slip purpose.
As preferably, described copper sheathing length is 50mm---70mm, copper sheathing wall thickness 2mm---5mm.It is simple in structure, reasonable in design, and the stretching resistance of conductor joint is improved, and reaches anti-slip purpose.
As preferably, described copper sheathing adopts the red copper material to be made into integration.Production cost is cheap relatively, working strength height, safe and reliable.
Therefore, the utlity model has that frictional force is big, tensile strength is high, be difficult for pulling after the conductor butt joint, low production cost, characteristics such as easy and simple to handle.
Description of drawings
Accompanying drawing 1 is a kind of structural front view of the present utility model.
Accompanying drawing 2 is a kind of sectional schematic diagrams of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
A kind of extrusion molding conductor anticreep connector comprises the copper sheathing that is arranged on two sections conductor joints, and copper sheathing 1 endoporus is provided with triangle flute profile screw thread 2, and the internal diameter of copper sheathing is greater than the diameter of conductor 3.Docking calculation: select for use about a segment length 60mm, wall thickness 3mm, endoporus is a triangle flute profile screw thread, tooth depth 1.5mm, pitch 1.5mm, the screwed hole internal diameter is than the copper sheathing of the big 0.05～0.1mm of conductor nominal diameter, the copper sheathing material is a red copper, the conductor end face that will dock saw is neat, respectively fills in about copper sheathing 30mm, if be difficult to fill in available file outer through place under repair to conductor, compress on the external diameter of copper sheathing with hydraulic press then, pressure is 80Mpa, and special-purpose jig is arranged on the hydraulic press, selects for use according to conductor sizes, compress back emery wheel reconditioning copper sheathing external diameter, guarantee that external diameter herein is less than the diameter of conductor, to guarantee joint safety smoothly by core rod, the conductor butt joint before coiling on going out cooling water pipe through extrusion molding cuts out joint.
The original smooth copper sheathing of endoporus that adopts connects during the conductor butt joint, because endoporus is smooth, coefficient of friction is little, the phenomenon that has slippage to disconnect after the conductor butt joint takes place, and tracing it to its cause is that inner hole friction force is not enough, and endoporus adopts the triangular form screwed hole now, through making the surface of thread embedded conductor after compressing, it has increased skin-friction coefficient, and the stretching resistance of conductor joint is improved, and reaches anti-slip purpose.
