Abstract
The utility model relates to a seal device used in the metal wire connection, belonging to the electrical equipment manufacturing technical field. A connecting structure for the lead of the electrical equipment comprises a coil winding located inside the electrical equipment, and an external power cord; and the connecting part between the end part of the coil winding and the external power cord is enwrapped with an insulating layer. The insulating layer is a solid layer which is formed after being dipped in the liquid insulating material. The coil winding is produced with enameled wires; after the paint at the end part of the coil winding is removed, the end part is electrically connected with the external power cord. The external power cord and the connecting end of the coil winding inside the electrical equipment are connected through tin soldering. The utility model has the advantages that the device enables the connecting part between the end part of the coil winding and the external power cord to be enwrapped with the insulating layer so as to achieve good sealing performance; compared with the traditional plastic casing and hot melt adhesive way, the device is simpler in structure and only uses one type of material; moreover, the device has simple technique, easy production and low cost.
Description
Technical field:
The utility model relates to the sealing device that a kind of plain conductor connects, and belongs to electric equipment and makes production technical field.
Background technology:
At present, the link of electric equipment coil windings and circumscripted power line is general to use hollow plastic cement shrink sleeve to entangle, and after the heating of plastic cement heat-shrinkable T bush, the inside is filled PUR and dissolved to seal.Because of the PUR of filling is lower with outside heat-shrinkable tube heatproof, inner PUR runs off under certain temperature conditions easily, and loses sealing effectiveness, and the air that bleeds causes the electric wire oxidation.It is aging under high-temperature condition outside thermal contraction casing tube to occur, thereby loses the effect of contraction and insulation after heat-shrinkable tube lost efficacy.On the other hand, in welding or when riveted joint,, the coupling part occurs sharp edge, burr easily and causes casing damage and lose sealing effectiveness.
The utility model content:
The sealing device that the purpose of this utility model is to provide a kind of plain conductor to connect, its good airproof performance, easy to manufacture, cost is low.
The utility model is achieved through the following technical solutions: the sealing device that a kind of plain conductor connects comprises the coil windings and the circumscripted power line that are positioned at inside electric appliance, the junction coated insulation layer of the end of coil windings and circumscripted power line.
The utlity model has following advantage: with the end of coil windings and the junction coated insulation layer of circumscripted power line, good airproof performance is than traditional plastic casing-pipe and PUR mode, structure is simpler, only uses a kind of material, and technology is simple, easy to manufacture, cost is lower.The junction sharp edge, burr occur and also is covered by the insulating barrier the inside, does not influence sealing effectiveness.
Above-mentioned insulating barrier is the solid-state insulating barrier that forms by dipping in liquid state or powder insulation material.
Above-mentioned described coil windings is copper enamelled wire or aluminium enamel-covered wire manufacturing, is electrically connected with circumscripted power line behind the end coating removal of coil windings.Circumscripted power line adopts soldering or riveted joint to be connected with inside electric appliance coil windings link.
Above-mentioned described solid-state insulating barrier can plastic cement, resin manufacture.
Above-mentioned described electric equipment can be motor, generator or transformer.
Above-mentioned described coil windings is wrapped on the core of circumscripted power line, and insulating barrier can be coated on the core.
Above-mentioned described coil windings is wrapped on the core and insulated hull of circumscripted power line, and insulating barrier can be coated on core and the insulated hull.This mode sealing is more strengthened, and coil windings, circumscripted power line and insulating barrier are connected more closely and are reliable, are difficult for getting loose.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is done detailed explanation.
Fig. 1 is the structural representation of first embodiment of the present utility model;
Fig. 2 is the structural representation of second embodiment of the present utility model;
Embodiment:
Embodiment 1: as shown in Figure 1, the utility model comprises coil windings 1 and the circumscripted power line 2 that is positioned at inside electric appliance, the junction coated insulation layer 3 of the end of coil windings 1 and circumscripted power line 2.Described insulating barrier 3 is the solid-state insulating barriers that form by dipping in liquid state or powder insulation material.Described coil windings 1 is the enamelled wire manufacturing, is electrically connected with circumscripted power line 2 behind the end coating removal of coil windings 1.The end of coil windings 1 is connected by soldering or riveted way with circumscripted power line 2.Solid-state insulating barrier can plastic cement, resin manufacture, and circumscripted power line 2 comprises core 21 and insulated hull 22, and coil windings 1 is wrapped on the core 21 of circumscripted power line 2, and insulating barrier 3 can be coated on the core 21.
Embodiment 2: as shown in Figure 2, doing improvement on the basis of embodiment 1: coil windings 1 is wrapped on the core 21 and insulated hull 22 of circumscripted power line 2, and insulating barrier 3 can be coated on core 21 and the insulated hull 22.This structure just begins sealing from insulated hull 22, and this mode sealing is more strengthened, and coil windings, circumscripted power line and insulating barrier are connected more closely and reliably, are difficult for getting loose.
Manufacturing process of the present utility model is: elder generation is with the end coating removal of coil windings 1, connect circumscripted power line 2 by soldering or riveted way then, the end of coil windings 1 and the junction of circumscripted power line 2 are immersed in the insulating material 3 of liquid or powdery, after detaching cooling then, form solid-state insulation enamelled coating 3.
