Abstract
The utility model discloses an electric induction coil, comprising a magnet ring, an aluminum enamelled wire and a copper lead wire, wherein the magnet ring is made of a ferromagnetic material; the aluminum enamelled wire is wound on the magnet ring and extends out with a tap; and the copper lead wire is connected with an exposed aluminum core of the tap. The electric induction coil is characterized in that the copper lead wire and the aluminum core are tightly compacted through a copper pressing sheet to keep in contact; and the copper pressing sheet is coated outside copper and aluminum and circumferentially sealed. By utilizing the electric induction coil, the weldability of the electric induction coil per se and other elements is improved, and the defects of wire breaking due to twist joint of a copper wire and an aluminum wire and poor contact of the copper and the aluminum caused by long term use of the electric induction coil can be avoided.
Description
Technical field
The utility model relates to a kind of inductance coil.
Background technology
The copper valency rises violently in recent years, and for reducing production costs, the inductance coil that uses aluminium enamel-covered wire to make is more and more.But adopt the inductance coil of aluminium enamel-covered wire coiling,,, then be difficult to guarantee welding quality if directly tap is welded mutually with circuit board or other element because the easy oxidation of aluminium causes the solderability of inductance coil tap not good.In the prior art, common way is a soldering copper lead-in wire in the aluminium tap, the copper lead-in wire is welded together with other element again; The shortcoming of this method is because the aluminium tap is different with the material of copper conductor, and general soldering rosin joint can occur when connecting, and this rosin joint very easily causes short circuit, thereby influences the normal operation of equipment; For overcoming the defective of the easy sealing-off that exists in the welding of copper and aluminum steel, people can only adopt the high scolder of price to carry out welding between the copper aluminium, and this has increased the cost of manufacture of inductance coil undoubtedly again.It is aluminum steel and copper cash to be intertwined draw the copper cash tap that way is also arranged, but when aluminum steel or copper cash were thin, this winding made line be easy to fracture, and the electric conductivity of gained inductance coil often can not guarantee.Other has way is to put copper protective layer outside aluminum steel, welds copper cash again and makes the copper tap, and still this copper protective layer is along with the use of product comes off easily.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of solderability good inductance coil.
For solving above technical problem, the utility model is taked following technical scheme:
A kind of inductance coil comprises the magnet ring made by ferromagnetic material, is wound on the described magnet ring and the aluminium enamel-covered wire of two ends coating removal skin and the copper lead-in wire that is connected with the described two ends of described aluminium enamel-covered wire;
According to the utility model, the described two ends of described aluminium enamel-covered wire contact with described copper lead-in wire, compress the copper compressing tablet that the two is kept in touch thereby described inductance coil also comprises the described two ends and the described copper lead-in wire that are used for described aluminium enamel-covered wire.
According to the utility model, described copper compressing tablet is that peripheral described two ends and the described copper that is packaged in described aluminium enamel-covered wire hermetically goes between outer.
In the inductance coil, coil can be stretched out usually in the two ends of enamelled wire, and the two ends of stretching out are called as " tap ".The end of tap is understood the coating removal skin usually, exposes core, so that join with other element.
According to the utility model, two tap end coating removal skins of described inductance coil expose the aluminium core, with itself and copper lead-in wire side by side, the copper compressing tablet is wrapped in the described copper cash and the aluminum steel outside hermetically and compresses with press.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
Adopt aluminium enamel-covered wire inductance coil of the present utility model in two taps, to draw two copper lead-in wires, can improve the weldability of inductance coil and other elements, two copper lead-in wire compresses with the copper compressing tablet of aluminum steel tap by the periphery sealing, can avoid the copper aluminum steel to twist joint easily making can causing after electric wire fracture and the long-term use of inductance coil the shortcoming of copper aluminium loose contact.
Description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing and concrete execution mode:
Fig. 1 is the schematic diagram that adopts inductance coil of the present utility model.
Wherein: 1, magnet ring; 2, aluminium enamel-covered wire; 20, tap; 200, aluminium core; 3, copper lead-in wire; 4, copper compressing tablet.
Embodiment
As shown in Figure 1, according to the inductance coil of present embodiment, comprise the magnet ring 1 made by ferromagnetic material, be wound on the described magnet ring 1 and the aluminium enamel-covered wire 2 of two taps, 20 coating removal skins and the copper lead-in wire 3 that is connected with described tap 20;
In the present embodiment, one section aluminium core 200 of described tap 20 coating removal skins contacts with copper lead-in wire 3, and described aluminium core 200 and copper lead-in wire 3 compress by copper compressing tablet 4 and keep in touch.
Described copper compressing tablet 4 compresses by press, and periphery is packaged in outside aluminium core 200 and the copper lead-in wire 3 hermetically.
According to the inductance coil of present embodiment by the copper wire bonds on Inductive ballast, the products obtained therefrom quality is good, uses contactless phenomenon such as bad to occur for a long time.
More than the utility model has been done detailed description; its purpose is to allow the personage that is familiar with this art can understand content of the present utility model and is implemented; can not limit protection range of the present utility model with this; all equivalences of doing according to spirit of the present utility model change or modify, and all should be encompassed in the protection range of the present utility model.
