A kind of structure of the crosslinked cable hot melting connector of the utility model specifically between cable connect as follows, two end lines of removal
The protective layer 1 of cable 2 exposes cable 2；Peel off the copper shield 10 and cable outer semiconducting layer 7 outside cable 2；Stripped cable 2 is simultaneously revealed
Cable insulation layer 21, conductor shield 11 and cable conductors 12 out；It is set on any cable 2 and matches with 1 size of protective layer
Heat-shrink tube, after conveniently completing, heat-shrink tube energy effective protection connector.Concrete operations in step 2 are as follows: two sides cable 2 is flat
Row is in same level, to good phase sequence, measures the distance that each phase sequence cable 2 differs, if both ends cable difference 1000mm and
Within, increase by one section and the fusion body 31 of 12 same size of cable conductors, facilitates the easy to operate of later period.It is adopted in the utility model
It is that the mode that hot-die heats heats fusion body 31 and both ends cable conductors 12 integrally, also needs to polish after the cooling period, make
It is consistent with the diameter of both ends cable conductors 12 to obtain interface.Connection cables conductor 12: two end cables of measurement differ distance, separately take one
The fusion body 31 of section matching two end cables difference distance, Exothermal Weld handles the both ends of fusion body 31, so that 31 both ends of fusion body
The cable conductors 12 of welding both ends cable 2 respectively；
Secondly in the production process, the oxide layer of 31 upper surface of grinding process cable conductors 12 and fusion body is also needed, and clear
Clean fusion body 31, conductor shield 11 and cable conductors 12；In the winding side that cable conductors 12 and fusion body 31 are overlapped using half
Formula carries out spooling semiconductive band 321；Continue spooling semi-conductive screen band 322 outside semiconductive band 321, and spooling is at both ends
On the conductor shield 11 of cable, and spooling depth is 10-20mm, finally obtains separation layer 32.It is middle to be polished using sand paper
, fusion body 31, conductor shield 11 and cable conductors 12 need to clean out, and no person influences the quality of connector；Semiconductive packet
Band 321 needs spooling close, ensure that the insulation between cable conductors 12 and conductor shield 11, prevents electric discharge from occurring, semiconductive
Band 321 needs two layers of spooling；Semi-conductive screen band 322 needs three layers of spooling, and spooling is in the conductor shield 11 of two end cables
On, prevent spooling Discharge Phenomena not in place.
Polyethylene film is wound outside separation layer 32, polyethylene film is wrapped in the cable outer semiconducting layer 7 of both ends cable 2
Between, the canoe of rounding off is used between polyethylene film and cable outer semiconducting layer 7；In the polyethylene that winding is completed
Heat-resisting pressure pipe of the thin film coat dress for sizing, and 1-2 layers of aluminium-foil paper are wound outside heat-resisting pressure pipe, using PI film by aluminium
Foil paper is tied tight on heat-resisting pressure pipe, and stock mould is obtained；Heat-shaping mould, is thermally equivalent on the outside of stock mould, and heating temperature is
165-200 DEG C, heating time 35-45min, until the polyethylene film in stock mould is by semi-conductive screen band 322 and conductor
The hot melt of shielded layer 11 is integrated, and is stopped heating, is obtained insulator 33；After pattern and primary insulation body 33 undetermined is cooling, it is fixed to remove
Pattern, sanding and polishing insulator 33 so that insulator 33 with 21 rounding off of cable insulation layer.Polyethylene film and two end lines
The junction of cable 2 needs rounding off, and no person influences quality；Heat-resisting pressure pipe can use heat resistant rubber pressure pipe, can be effective
It prevents polyethylene film heat from melting and irregular shape occurs, so that final product quality is poor；Aluminium-foil paper can guarantee heat-resisting pressure pipe
Be heated evenly, PI film have good heat resistance, for tying tight, effect is good.Using electric heating in the utility model
Rubber strip uniform winding heats up heating at stock mould, and the gap of electric heating rubber strip spooling needs uniform, it is ensured that polyethylene
The quality that film melts.Also cable conductors 12 are heated using induction heating mode in the utility model, heating temperature is
125-135 DEG C, heating time 30-40min, the thawing speed of cable insulation layer 21 is further improved, so that cable insulating
Layer 21 mutually melt very well with polyethylene film, realize whole insulated enclosure.
Shielding paint is coated outside the insulator 33 obtained by aforesaid operations, shielding paint layer 6 is obtained after air-drying, and paint in shielding
The 6 outer zinc-plated copper mesh of spooling of layer, obtain zinc-plated copper mesh layers 5, and zinc-plated copper mesh layers 5 connect the copper shield 10 of two end cables；This implementation
In example, in the shielding outer spooling 1-2 layers of semi-conductive rubber self-adhesive tape of paint layer 6, connector outer semiconducting layer 13 is obtained；It polishes two end cables
10 fracture of copper shield on oxide layer, grinding depth 100-120mm, in the outer spooling galvanized copper of connector outer semiconducting layer 13
Net, on zinc-plated copper mesh spooling to the copper shield 10 polished.Copper shield 10 only with sand paper need to polish, zinc-plated
Copper mesh must carry out spooling on the copper shield 10 of both ends cable 2, avoid the occurrence of the phenomenon that leakage twines, the both ends of zinc-plated copper mesh must
It must carry out tightening fixation.
In the present embodiment, with PVC film, by step 5, treated that cable 2 is fixed and binds；Outside PVC film
Spooling tin-coated copper works out band, and tin-coated copper works out the armor of band connection both ends cable 2, obtains tin-coated copper establishment belt 8；Tin plating
Copper works out the outer spooling adhesive waterproof tape of belt 8, and connects the oversheath of both ends cable 2, obtains marine glue belt 9；In adhesive waterproof tape
Heat-shrink tube is shunk outside layer 9, and winds 1-2 layers of adhesive waterproof tape and PVC tape at the both ends of heat-shrink tube, completes the docking work of end
Make.It also needs to carry out spooling at least two layers of adhesive waterproof tape outside PVC film, which matches with inner sheath, forms interior protection
Layer；Tin-coated copper establishment belt 8 matches with armor, the shielding being accomplished that between cable 2 and outside；In spooling adhesive waterproof tape
When layer 9, the oversheath by both ends cable 2 is also needed to polish, facilitates carry out spooling, at least two layers of spooling of marine glue belt 9.?
It also needs to wind armoring progress mechanical protection outside heat-shrink tube, finally just obtains cross-inked polyethylene power cable hot melting connector.
This crosslinked cable hot melting connector is easy to make, easy to operate, low cost, low in cost, can effectively keep away
Exempt from interfacial air gap electric discharge, securely and reliably, manufacturing process realizes rapid-maintenance without operating to remaining cable.
The above, the only better embodiment of the utility model, but the utility model is not limited to above-mentioned reality
Example is applied, as long as its technical effect for reaching the utility model with any same or similar means, all should belong to the utility model
Protection scope.
