The utility model has the advantages of simple structure and reasonable design, through the design of this kind of structure, performance is more outstanding, need not to bend, reduces because of the side crack that bends and cause, increases the yield, in the space of the same size, the coil can be the coiling bigger, and space utilization is high, has promoted the performance.

Description

Inductance structure capable of improving performance

Technical Field

The utility model relates to an inductance technical field specifically is an inductance structure that can promote performance.

Background

The existing integrally formed inductance thick-wire-diameter product is mostly a bent terminal after flattening, personnel make mistakes easily in operation, defective products easily occur, the working efficiency is low, and on the other hand, in the space with the same size, the coil winding is small, the space utilization rate is low, and the performance is not high.

SUMMERY OF THE UTILITY MODEL

The utility model provides a can promote inductance structure of performance need not to bend, reduces because of the side crack that bends and cause, increases the yield, in the space of the same size, the coil can be the coiling bigger, and space utilization is high, has promoted the performance.

The utility model relates to an inductance structure that can promote performance, electrode on base member and base member, the base member include elliptical coil and iron powder piece, the electrode grind through the elliptical coil both ends and tie and form to carry out copper-plated nickel tin after printing silver thick liquid on the surface, elliptical coil's main part is wrapped up it by the iron powder piece.

The utility model discloses in: the elliptic coil is provided with two end parts, namely a coil inlet end and a coil outlet end, and the middle part of the elliptic coil is in an elliptic spiral shape, namely the elliptic coil is formed by spirally winding; the two ends of the elliptical coil are led out from the same end face.

The utility model discloses in: the iron powder block is a stainless steel alloy iron powder block.

Through the technical scheme, the beneficial effects of the utility model are that: the utility model has the advantages of simple structure and reasonable design, through the design of this kind of structure, performance is more outstanding, need not to bend, reduces because of the side crack that bends and cause, increases the yield, in the space of the same size, the coil can be the coiling bigger, and space utilization is high, has promoted the performance.

Drawings

Fig. 1 is a schematic view of a fixing structure of the coil of the present invention;

fig. 2 is a schematic structural diagram of the present invention.

In the figure: 1. a coil; 2. an end portion; 3. a substrate; 4. and an electrode.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

It can be seen from fig. 1-2 that an inductance structure that can promote performance, electrode 4 on base member 3 and the base member, base member 3 include oval coil 1 and iron powder piece, electrode 4 grind through oval coil 1 both ends and flat form to carry out copper-plated nickel tin after the printing silver thick liquid on the surface, oval coil 1's main part is wrapped up it by the iron powder piece. The elliptical coil 1 is provided with two end parts, namely a coil inlet end and a coil outlet end, and the middle part is in an elliptical spiral shape, namely the elliptical wire is spirally wound; both end portions of the elliptical coil 1 are led out from the same end face. The iron powder block is a stainless steel alloy iron powder block.

The utility model has the following manufacturing process:

step one, wire winding spot welding: winding the enameled wire into a coil in a spiral shape along the elliptic center column, and respectively welding two ends of the coil on two pins of the guide sheet to form a spot welding coil;

step two, forming: placing the spot welding coil into a forming die for forming;

step three, cutting the line: cutting off the redundant part of the enameled wire and the guide sheet from the product;

step four, terminal processing: and (4) carrying out grinding, silver coating and electroplating on the terminal.

The original coil is led out from two ends (the folded angle part occupies space), and then needs to be flattened and bent, so that a certain space needs to be reserved between the coil and the edge of the body. And the utility model discloses in the structure, both ends are drawn forth at the same face, need not to bend, the advantage has two: firstly, the coil can be wound more than the original coil, so that the performance is improved; and secondly, no bending exists, so that the conditions of side cracking, damage and the like caused by bending are avoided, and the yield is improved.

The utility model discloses the concrete application way is many, and the above-mentioned only is the preferred embodiment of the utility model, should point out, to ordinary skilled person in this technical field, under the prerequisite that does not deviate from the utility model discloses the principle, can also make a plurality of improvements, and these improvements also should be regarded as the utility model discloses a scope of protection.
