Abstract
The utility model relates to the technical field of electromagnetic oven, and particularly belongs to a coil panel which is coiled by an enameled aluminum wire. The utility comprises a coil panel bracket, a soft magnet, a coil which is coiled by an enameled wire bunch, and a terminal. The enameled wire is an aluminum enameled wire which is connected to a copper terminal. And the copper terminal and the aluminum enameled wire are wrapped and sealed by a tin layer. The utility model has the advantages that the copper terminal and the aluminum wire which are coated by the tin layer so as not to contact the outside air easily, thereby efficiently avoiding oxidation. The gap between the copper terminal and the aluminum wire is reduced, thereby efficiently avoiding arcing which is caused by the big gap between the copper terminal and the aluminum wire and therefore reduces the service life greatly.
Description
Technical field
The utility model relates to a kind of electromagentic furnace technology field, specifically belongs to a kind of coil panel with the enamel insulated aluminium wire coiling.
Background technology
At present, electromagnetic oven is used widely, its coil panel all is to adopt traditional enamel-cover copper core to be entwined for a long time, price by copper is more expensive, make the manufacturing cost of coil panel high, and the density of copper is bigger, the weight of coil panel is heavier, increase cost of transportation, the coil panel that occurs adopted copper-covered aluminum-core afterwards, therefore in light weight, cost is low, announce that as Patent Office of the People's Republic of China name is called a kind of electromagnetic oven enamel insulated aluminium wire, the enamel insulated aluminium wire coil panel, patent No. ZL200520059731.X, structure is: by coil bracket, soft magnet, the coil of the flat coiling of enamel-cover wire harness, sleeve pipe, formations such as terminal, the coil of the flat coiling of its enamel-cover wire harness by enameled copper clad aluminum line or enamel insulated aluminium wire in same plane around forming; The coil horizontal of the flat coiling of enamel-cover wire harness is on coil bracket; Soft magnet is installed in the coil disc of electric stove support, and electric current can produce the alternation magnetic line of force by the coil on the coil panel, and the magnetic line of force forms electromagnetic circuit at pan on the electromagnetic oven and the soft magnet on the coil panel, thereby forms the operating state of electromagnetic oven.Have following weak point in actual applications: 1, copper tip is provided with chuck, and is sandwiched on the copper-clad aluminum conductor, and the joint produces high temperature in the middle of using, and its aluminum steel is had partly be to expose oxidized easily and easily be corroded shortening aluminum steel useful life; 2, copper tip and aluminum steel can utilize copper sheath to join with tin with copper tip, but because soldering connects copper sheath, and its warping resistance sexuality is poor, institute be long useful life with the tin characteristic that is connected.
The utility model content
The purpose of this utility model is to overcome the shortcoming that said structure exists, and the coil panel of a kind of weight that alleviates electromagnetic oven, anti-oxidant, the anticorrosion and aluminium enamel-covered wire that increases the service life is provided.
The utility model is realized with the following methods: be made of the coil of coil bracket, soft magnet, the coiling of enamel-cover wire harness, terminal etc., its described enamelled wire is an aluminium enamel-covered wire, and aluminium enamel-covered wire is connected with copper tip, and copper tip and aluminium enamel-covered wire are by the sealing of tin layer parcel.
Described coil bracket is drawn two aluminium enamel-covered wires, and the aluminum steel exit of aluminium enamel-covered wire is connected with the firm of copper tip, is welded with the tin layer between the aluminum steel exit of aluminium enamel-covered wire and the copper tip end.
The termination of described aluminium enamel-covered wire is with sleeve pipe.
The beneficial effects of the utility model are: 1, copper tip is difficult for contacting with extraneous air for tin layer parcel with aluminum steel, effectively do oxidation, reduce in the gap between copper tip and the aluminum steel, prevents that effectively the gap Da Yi generation electric arc of copper tip and aluminum steel from making significantly reduce its useful life.
Description of drawings:
Fig. 1 is the structural representation of utility model.
Fig. 2 is the syndeton schematic diagram of aluminium enamel-covered wire and copper tip.
Fig. 3 is the structural representation of another embodiment of Fig. 2.
Specific embodiment
Below in conjunction with accompanying drawing the utility model is made concrete further instruction.
As shown in the figure: be made of the coil of coil bracket 1, soft magnet, the coiling of enamel-cover wire harness, terminal etc., its described enamelled wire is an aluminium enamel-covered wire 2, and aluminium enamel-covered wire 2 is connected with copper tip 3, and copper tip 3 and aluminium enamel-covered wire 2 are by the 4 parcel sealing of tin layer.
Described coil bracket 1 is drawn two aluminium enamel-covered wires 2, and the aluminum steel exit of aluminium enamel-covered wire 2 is connected with the firm of copper tip 3, is welded with tin layer 4 between the aluminum steel exit of aluminium enamel-covered wire 2 and copper tip 3 ends.
The termination of described aluminium enamel-covered wire 2 is with sleeve pipe.
This product surpasses 10 times in the warping resistance performance in test, fails to fracture; Antioxygen gasification and corrosive nature improve greatly; Safety is by 8 to 15 peace electric currents in testing current, and the temperature rise of core is lower than 145 degree; In the moving test of tension, 10 kilogram weights of pullings in 1 minute are according to keeping constantly; Inductance value remains on 100 positive and negative 5% errors that are no more than.
Claims (3)
1. the coil panel of an aluminium enamel-covered wire, constitute by the coil of coil bracket, soft magnet, the coiling of enamel-cover wire harness, terminal etc., it is characterized in that: described enamelled wire is an aluminium enamel-covered wire, and aluminium enamel-covered wire is connected with copper tip, and copper tip and aluminium enamel-covered wire are by the sealing of tin layer parcel.
2. the coil panel of a kind of aluminium enamel-covered wire according to claim 1, it is characterized in that: described coil bracket is drawn two aluminium enamel-covered wires, the aluminum steel exit of aluminium enamel-covered wire is connected with the firm of copper tip, is welded with the tin layer between the aluminum steel exit of aluminium enamel-covered wire and the copper tip end.
3. the coil panel of a kind of aluminium enamel-covered wire according to claim 2, it is characterized in that: the termination of described aluminium enamel-covered wire is with sleeve pipe.
