Technical Field

The invention relates to the field of electrified lead repair, in particular to a lead breaking and connecting device.

Background

In actual production activities, if a circuit is broken, workers need to reconnect the two ends of the broken wire.

Patent application publication No. CN107533884A discloses a method of using a temporary conductor as a reusable tool to repair, repair or replace a conductor for at least one powered phase, the method comprising stringing the temporary conductor between support structures at either end of a first section, subsequently energizing the temporary conductor by bringing the temporary conductor to the voltage potential of that phase and electrically paralleling the temporary conductor with the powered phase, de-energizing that phase and then repairing, repairing or replacing the powered-off powered phase, re-energizing that phase and electrically paralleling the powered phase, de-energizing the temporary conductor and removing the temporary conductor for subsequent reuse as a reusable tool in a second section of the powered phase.

However, when a maintenance person uses the temporary wire in the technical scheme to maintain the circuit, the insulation skin of the wire near the breakpoint portion needs to be peeled off by means of a tool, then the two ends of the temporary wire are respectively connected to the two ends of the broken wire, and if the maintenance person does not carry the peeling tool, the maintenance work cannot be performed, so that the flexibility of the technical scheme is low.

Disclosure of Invention

The invention provides a wire breaking and connecting device, which aims to improve the flexibility of connecting and maintaining a wire breakpoint by a maintenance worker.

In order to solve the technical problems, the patent application adopts the technical scheme that:

When the power line has an open circuit fault, if the two ends of the broken wire are connected under the condition that the power supply of the circuit is not cut off by maintenance personnel, the circuit can be switched on and off instantly to generate larger current, so that when the two ends of the broken wire are close to each other, a large amount of electric arcs (sparks) can be generated between the two ends of the broken wire, the wiring difficulty of the maintenance personnel is larger, and the wiring process has larger danger.

After the circuit is reconnected, in the process that two ends of the broken lead are connected by a maintenance worker, because the instantaneous current of the circuit is not generated, electric arcs (sparks) are not easy to generate between two ends of the broken lead, the maintenance worker can easily wire, and the safety of the maintenance worker in wiring is improved.

The working principle of the patent application embodiment of the invention is as follows:

the following takes as an example the case where the number of ring-cutting cutters is two and is respectively disposed on the first clamping block 51 and the second clamping block 52, and the number of cross-cutting cutters is two and is respectively disposed on the first clamping block 51 and the second clamping block 52:

when a maintenance worker needs to wire the breakpoint of the wire, the two locking nuts 8 on the wire stripping clamp 5 connected with the first connecting wire 1 are loosened, so that the first clamping block 51 and the second clamping block 52 are separated under the elastic action of the return spring 9; then, a maintenance worker places a wire between the first wire groove 517 and the second wire groove 527, presses the first clamping block 51 and the second clamping block 52 to enable the wire to be located in a clamping groove formed by the first wire groove 517 and the second wire groove 527, enables the first ring cutting cutter 514 and the second ring cutting cutter 524 to be in contact with each other and extrude an insulating skin of the wire, and then sequentially screws up the locking nuts 8 on the two locking screw rods 7; then the wire stripping clamp 5 rotates around the axis of the wire, so that the first circular cutting knife 514 and the second circular cutting knife 524 circularly cut the insulating sheath of the wire; when a maintenance person rotates the wire stripping clamp 5 around the axis of the wire for one circle, the locking nut 8 is screwed down once until the insulating skin of the wire is cut off, so that an annular notch appears on the insulating skin of the wire.

After the maintenance personnel complete the circular cutting of the insulating sheath of the conducting wire, the locking nuts 8 on the two locking screw rods 7 are sequentially loosened, the conducting wire is taken out and rotated by 90 degrees, then the conducting wire is placed between the first clamping block 51 and the second clamping block 52, the first transverse cutting cutter 516 and the second transverse cutting cutter 526 are aligned to the annular notch on the insulating sheath of the conducting wire, then the first clamping block 51 and the second clamping block 52 are closed, the locking nuts 8 on the two locking screw rods 7 are sequentially screwed, the first transverse cutting cutter 516 and the second transverse cutting cutter 526 are enabled to be contacted with and extrude the insulating sheath of the conducting wire, meanwhile, the first idler wheels 512 and the second idler wheels 522 are enabled to be abutted against the outer peripheral surface of the conducting wire, and then the locking nuts 8 on the two locking screw rods 7 are sequentially screwed; at this time, a maintenance person only needs to pull the wire stripping clamp 5 back and forth along the axis of the wire, so that the first transverse cutter 516 and the second transverse cutter 526 can cut the insulating sheath of the wire along the axis of the wire; when a maintenance person pulls the wire stripping clamp 5 back and forth along the axis of the wire once, the locking nut 8 is screwed down once until the insulating skin of the wire is cut open, so that two linear notches which extend along the axis of the wire and are symmetrical to the axis of the wire appear on the insulating skin of the wire.

After the maintenance personnel finishes the circular cutting and transverse cutting of the insulation sheath of the wire, the insulation sheath of the wire is peeled manually or by means of a tool such as pliers, so that the wire core of the wire is exposed, and then the first wire clamp 511 and the second wire clamp 521 on the wire stripping clamp 5 are used for clamping the wire core at one end of the broken wire, so that the first connecting wire 1 is communicated with the wire core at one end of the broken wire. The maintenance personnel clamp the broken wire core at the other end of the wire with the first wire clamp 511 and the second wire clamp 521 on the wire stripping clamp 5 connected with the second connecting wire 2 according to the operation, so that the second connecting wire 2 is communicated with the broken wire core at the other end of the wire.

When the maintenance personnel use the first connecting wire 1 and the second connecting wire 2 to be respectively communicated with the two ends of the broken wire one by one, the circuit can be conducted again by closing the air switch 3, and the maintenance personnel can connect the two ends of the broken wire at the moment; this technical scheme has improved the security that maintenance personal carried out the wiring.
