Abstract
The utility model discloses a foil coil, which comprises a coil (1), a foil (3) and an outlet end (2), wherein the starting end and the tail end of the coil (1) are connected with the foil (3), and the outlet end (2) is connected with the foil (3) into one body. With the above structure, the outlet end of the coil is not needed to be additionally welded and led out, which directly adopts original foil materials to be led out, can guarantee enough current-carrying contact area, and can avoid the phenomenon of unsoldering.
Description
Technical field
The utility model relates to a kind of coil, specifically is a kind of foil coil that is used for transformer.
Background technology
Coil in the general transformer forms by electric conducting material (copper or aluminium) coiling, and very thin and width and coil height are similar to and are referred to as paper tinsel when high when this electric conducting material, and coil just is referred to as foil coil, and the material of paper tinsel generally adopts copper or aluminium.Traditional foil coil lift one's head general employing copper bar or aluminium row and Copper Foil or aluminium foil welding, and then draw.But this structure exists shortcoming: in the time of the thinner thickness of Copper Foil or aluminium foil, copper bar or aluminium row welding with it are just very difficult, be easy to cause Copper Foil or aluminium foil burn-through, thereby the contact area deficiency of current-carrying, can occur exerting oneself with regard to the phenomenon of sealing-off slightly, such coil exists very big hidden danger of quality.
The utility model content
Technical problem to be solved in the utility model is that a kind of foil coil that guarantees enough current-carrying contacts area, the sealing-off phenomenon can not occur is provided.
For solving the problems of the technologies described above, a kind of foil coil that the utility model provides comprises coil, paper tinsel, lifts one's head, and starting of described coil all is connected with paper tinsel with finishing up.Described lift one's head with paper tinsel be one.
After adopting above structure, owing to lift one's head and paper tinsel is an one, lift one's head and need not in addition welding and draw, directly adopt former foil material to draw, can guarantee enough current-carrying contacts area, also avoid occurring the sealing-off phenomenon.
Described lift one's head with paper tinsel be one, be meant coil to start and finish up promptly be lifting one's head of coil.After adopting this structure, more convenient processing is improved the quality of products.
Described paper tinsel is Copper Foil or aluminium foil.Because the flexibility of Copper Foil or aluminium foil is good, more conveniently changes the shape of paper tinsel as required and do not injure coil.
Description of drawings
Fig. 1 is the structural representation of existing foil coil;
Fig. 2 is the structural representation of the utility model foil coil;
Fig. 3 be the utility model foil coil lift one's head the manufacturing process structural representation.
Wherein, the utility model: 1, coil; 2, lift one's head; 3, paper tinsel; 4, datum line.
Prior art: 1-1, coil; 2-1, lift one's head; 3-1, paper tinsel.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
By the structural representation of existing foil coil shown in Figure 1 as can be known, existing foil coil comprises coil 1-1, lift one's head 2-1, paper tinsel 3-1, and the 2-1 that wherein lifts one's head draws after generally adopting copper bar or aluminium row and paper tinsel 3-1 welding.The unusual difficulty of welding when the thinner thickness of paper tinsel 3-1.
By the structural representation of the utility model foil coil shown in Figure 2 as can be known, the utility model comprises coil 1, paper tinsel 3, lifts one's head 2 that starting of described coil 1 all is connected with paper tinsel 3 with finishing up.Described lifting one's head 2 is one with paper tinsel 3, promptly coil 1 start and finish up promptly be coil 1 lift one's head 2.Described paper tinsel 3 is Copper Foil or aluminium foil.Need not copper bar or aluminium row welding like this and draw, directly adopt former foil material to draw, can guarantee enough current-carrying areas, the hidden danger of quality of also having avoided welding to bring.
Lift one's head structural representation as can be known by the utility model foil coil shown in Figure 3, when the starting or finish up of coil winding, Copper Foil or aluminium foil are cut into increase progressively step by step rectangular by length direction, each is rectangularly turned up with direction shown in the dotted line by datum line 4 then, stack as lead-out wire, promptly coil 1 lifts one's head 2.Be one because of Copper Foil or aluminium foil and lead-out wire like this, thereby avoided welding, made things convenient for processing, improved product quality.
Claims (3)
1, a kind of foil coil comprises coil (1), paper tinsel (3), lifts one's head (2), and starting of described coil (1) all is connected with paper tinsel (3) with finishing up, and it is characterized in that: described lifting one's head (2) is one with paper tinsel (3).
2, foil coil according to claim 1 is characterized in that: described lifting one's head (2) and paper tinsel (3) are one, be meant coil (1) to start and finish up promptly be lift one's head (2) of coil (1).
3, foil coil according to claim 1 and 2 is characterized in that: described paper tinsel (3) is Copper Foil or aluminium foil.
