Abstract
The utility model relates to a sealing structure applied to a motor winding lead. The sealing structure comprises a motor winding lead; the winding lead is connected with a section of lead cable; the winding lead is welded with a lead cable core via a conductive copper pipe; a plurality of rounds of silicone rubber self-adhering belt are wound at the junction of the conductive copper pipe and the lead cable insulation sleeve; the other end of the lead cable is sleeved with a sealed high-temperature natural silicone rubber protective cover; and a plurality of rounds of silicone rubber self-adhering belt are wound at the junction of the protective cover and the lead cable insulation protective sleeve. By adopting the sealing structure, the situation that dipping paint cannot infiltrate in the drying process of the dipping paint is ensured, and at the same time, the connected cable still be softened well to facilitate the connection of subsequent cables.
Description
Technical field
The present invention relates to the field of sealing technology of plain conductor, particularly be applied in the hermetically-sealed construction on the motor windings lead-in wire.
Background technology
The main processes of winding manufacturing comprises: material preparation, coil winding, rule, integer, wiring and welding, insulation processing, coating processing and quality inspection etc.After the manufacturing of winding each several part was accomplished, each end also needed to fix with colligations such as no latitude bands, also needs insulation impregnating to handle then, and common method has dipping lacquer to handle, and this processing procedure requires winding integral body is soaked into, then oven dry.The no latitude band of winding leads blank area parcel is also handled through this dipping lacquer, causes pigtail splice to harden after the oven dry, and this just makes the follow-up problem of bringing that is connected with feed cable; Influence sealing effectiveness, the lead-in wire position of sclerosis is difficult for fixing simultaneously, and it is chaotic to distribute at motor internal; Bring bigger trouble to installation; When motor rotation, said lead-in wire is arbitrarily swung at motor internal, has potential safety hazard.
Summary of the invention
The object of the invention just provides a kind of winding leads hermetically-sealed construction, and its good seal performance is handled the back lead ends through dipping lacquer and still kept softening, being connected of convenient simultaneously and feed cable.
The present invention adopts following technical scheme: the winding leads hermetically-sealed construction; Comprise the motor windings lead-in wire; Said winding leads is connected with one section leader cable, and said winding leads and leader cable core are through the contact tube welding, and some circle silicon rubber self-adhesive tapes are twined in said contact tube and leader cable insulating sleeve junction; The other end of said leader cable is with the natural silicon rubber high temperature protecting cover of sealing, and some circle silicon rubber self-adhesive tapes are twined in said protecting cover and leader cable cable insulation jacket junction.
Said winding leads and cable core are through the welding of silver-bearing copper filler, and the silicon rubber self-adhesive tape number of turns that twine said copper pipe and insulating sleeve junction, said protecting cover and cable insulation jacket junction is greater than two circles.
Technique effect: the present invention is through welding one section cable at winding leads; This cable and winding leads are with the copper pipe and the silicon rubber self-adhesive tape sealing of parcel in order, and the other end of cable seals with the silicon rubber high temperature protecting cover and the silicon rubber self-adhesive tape that wrap up in order, adopts this hermetically-sealed construction; Just guarantee in the paint-dipping drying process; Dipping lacquer can't infiltrate, and the cable that connects simultaneously still has softening preferably, and convenient follow-up cable connects use.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
As shown in Figure 1, the winding leads hermetically-sealed construction comprises motor windings lead-in wire 1; Winding leads is connected with one section leader cable 2; The leader cable core is wrapped with insulating sleeve 3, and winding leads and leader cable core 7 are through contact tube 6 welding, and some circle silicon rubber self-adhesive tapes 4 are twined in contact tube and leader cable insulating sleeve junction; The other end of leader cable is with the natural silicon rubber high temperature protecting cover 5 of sealing, and some circle silicon rubber self-adhesive tapes 4 are twined in protecting cover and leader cable cable insulation jacket junction.
Said winding leads and cable core are through the silver-bearing copper welding, and the silicon rubber self-adhesive tape number of turns that twine copper pipe and insulating sleeve junction, protecting cover and cable insulation jacket junction is all greater than two circles.
Technique effect: the present invention is through welding one section cable at winding leads; This cable and winding leads are with the copper pipe and the silicon rubber self-adhesive tape sealing of parcel in order, and the other end of cable seals with the silicon rubber high temperature protecting cover and the silicon rubber self-adhesive tape that wrap up in order, adopts this hermetically-sealed construction; Just guarantee in the paint-dipping drying process; Dipping lacquer can't infiltrate, and the cable that connects simultaneously still has softening preferably, and convenient follow-up cable connects.
