Abstract
The submersible motor winding of present invention offer and power connection structure, including motor winding wire joint and power cable pinout connector, motor winding wire joint and power cable pinout connector is opposing parallel overlaps, and a sheathed metal tube, metal tube fastens above-mentioned two joints by the way of cold welding, one layer of clay of metal tube outer cladding, the excircle of clay and the flush with outer surface of motor winding wire crust, motor winding wire crust is identical with the external diameter of power cable lead-out wire crust, one layer of heat-shrinkable T bush of the outer surface outer cladding of clay.Owing to the present invention uses said structure, two joints connected compared to the soldering mode of prior art do not have burr, neat appearance, metal tube outer cladding clay, PUR draw overcoat, internal residual air is squeezed out, eliminates electric discharge hidden danger, engineered joint, insulating resistance value, breakdown voltage value all improve a lot, soaking for a long time in water, stable performance, the service life of product extends.
Description
Technical field
The invention belongs to submersible motor field, particularly relate to a kind of submersible motor winding and be connected knot with power supply
Structure.
Background technology
Submersible motor is owing to using in water, and insulant used must be able to have in water for a long time good
Electrical insulation capability, can seal again simultaneously, contacts with electric with exclusion of water.Facts have proved: at diving electricity
In more than 100 year that machine comes into operation, statistics motor operation troubles there are about 50% and is above electric fault, and
Electric fault is mainly insulation breakdown or insulation resistance is low.Cause the most damage position of fault be around
Group and the connecting portion of outgoing cable, the attachment structure how designing a kind of novelty makes breakdown problem thoroughly solve
Will never occur, solve this hard nut to crack affecting motor reliability for many years, become this area
The problem of technical staff's research.
Summary of the invention
First the problem to be solved in the present invention is to provide the high submersible motor winding of a kind of reliability and power supply
Attachment structure.
For solving the problems referred to above, the technical solution used in the present invention: a kind of submersible motor winding is with power supply even
Access node structure, including motor winding wire joint and power cable pinout connector, described motor winding wire joint
Opposing parallel with described power cable pinout connector overlap, and a sheathed metal tube, described gold
Belong to pipe by the way of cold welding, fasten motor winding wire joint and power cable pinout connector, described gold
Belong to the flush with outer surface of one layer of clay of pipe outer cladding, the excircle of described clay and motor winding wire crust,
Described motor winding wire crust is identical with the external diameter of power cable lead-out wire crust, the outer surface of described clay
One layer of heat-shrinkable T bush of outer cladding.
Described two overlapping splice length together is more than or equal to 40mm.
The two ends of the more described clay of described heat-shrinkable T bush the most outwards extend a segment distance.
Described metal tube is at least colded pressing and is welded with two sections of downward depressed parts.
The present invention has the advantage that with good effect: due to metal sheathed at the overlapping splice of the present invention
Pipe, fastens two joints by the way of cold welding, two connects compared to what the soldering mode of prior art connected
Head does not has a burr, neat appearance, metal tube outer cladding clay, PUR draw overcoat, by internal residual
Gas of leaving a blank squeezes out, and eliminates the hidden danger of electric discharge, through the joint of this transformation, insulating resistance value, hits
Wear magnitude of voltage all to improve a lot, soak for a long time in water, stable performance, extend the service life of product；
Two overlapping splice length together is more than or equal to 40mm, convenient overlap joint, can ensure that cold welding simultaneously
Metal tube fastening strength.
Accompanying drawing explanation
Fig. 1 is the structural representation of patch panel of the present invention.
In figure: 1. power cable 2. winding wire 3. metal tube 4. clay 5. heat
Heat-Shrinkable Tubings 6 power cable pinout connector 7 winding wire joint.
Detailed description of the invention
The most with reference to the accompanying drawings the present invention is carried out explanation in greater detail, as it is shown in figure 1, a kind of submersible motor around
Group and power connection structure, including motor winding wire joint 7 and power cable pinout connector 6, described
Motor winding wire joint 7 and described power cable pinout connector 6 is opposing parallel overlaps, and overlap
If a metal tube 3, described metal tube 3 fastens motor winding wire joint 7 by the way of cold welding and moves
Power cable pigtail joint 6, described one layer of clay 4 of metal tube 3 outer cladding, the cylindrical of described clay 4
Week and the flush with outer surface of institute's motor winding wire crust, described motor winding wire crust and power cable are drawn
The external diameter of line crust is identical, one layer of heat-shrinkable T bush 5 of the outer surface outer cladding of described clay 4.Due to this
Metal tube 3 sheathed at bright overlapping splice, fastens two joints by the way of cold welding, compared to existing
Two joints having the soldering mode of technology to connect do not have burr, neat appearance, metal tube 3 outer cladding clay
4, PUR draw overcoat, internal residual air is squeezed out, eliminates the hidden danger of electric discharge, pass through
The joint of this transformation, insulating resistance value, breakdown voltage value all improve a lot, and soak for a long time in water,
Stable performance, extends the service life of product.
Further, overlap for convenience, can ensure that metal tube 3 fastening strength of cold welding, institute simultaneously
State two overlapping splice length together more than or equal to 40mm.
Further, the most thorough in order to what internal residual air was got rid of, described heat-shrinkable T bush 5 relatively institute
The two ends stating clay 4 the most outwards extend a segment distance.
Further, more preferable in order to what two joints were connected, it is to avoid the problems such as virtual connection produce, described metal
Pipe 3 is at least colded pressing and is welded with two sections of downward depressed parts.
Assembling process: metal canula is enclosed within some joint, by the two opposing parallel docking of joint (as
Fig. 1), fasten two joints to being colded pressing by metal canula by the machine of cold welding after connecting, then exist
Metal canula outer cladding clay 4, clay 4 overcoat heat-shrinkable T bush 5.
Above embodiments of the invention are described in detail, but described content has been only the preferable of the present invention
Embodiment, it is impossible to be considered the practical range for limiting the present invention.All according to the scope of the invention made equal
Deng change and improvement etc., within all should still belonging to this patent covering scope.
