Abstract
The utility model belongs to the field of magneto-electricity, in particular to an inductance component, which comprise a hollow magnetic cover with a groove, a magnetic bar and a coil. The hollow magnetic cover with the groove is in integral forming. The coil is provided with a coil part and an extension part, wherein the coil part is formed by winding a lead for a certain number of circles and the extension part is formed by extending outwards two ends of the coil part. The magnetic bar is installed at a hollow position of the coil, and the coil is inserted into an inner cavity of the hollow magnetic cover and fixed on the hollow magnetic cover through the extension part of the coil. During assembly of the inductance component, the hollow magnetic cover and the magnetic bar do not need a clamp for fixing, and increased inductance gap caused by expansion of fixing glue during roasting is not needed to be worried, and accordingly property and use efficiency of the complete inductance component are greatly improved. In addition, bad hidden dangers like EC type separation and I type separation generated due to the fact that the fixing glue is not tight during high-temperature backflow of inductance on a circuit board are avoided, and accordingly a user feels more relieved.
Description
Technical field:

Background technology:
Inductance element is important electron components and parts very in the electronic industry, traditional inductance element is seen shown in Fig. 1,2, upper I type magnetic core and the next EC type magnetic core and a coil combination form, the next EC type magnetic core is provided with a groove, be used for ccontaining coil, upper magnetic core is corresponding with it to cover, and gluingly connects through putting, technology such as baking again, makes two magnetic cores be combined into an inductance element.This inductance element, when two magnetic core point glue combinations, need use the fixing magnetic core up and down of anchor clamps, toast again behind the good glue of point, the air gap of magnetic core strengthens because the expansion of glue can make up and down when baking, also make magnetic core dislocation up and down easily, cause inductance to reduce, magnetic loss adds ambassador's inductance element application efficiency significantly to be reduced.On the other hand, in case fixing glue occurs bonding insecure, also can making up and down during in the circuit board through the high temperature reflux weldering, the magnetic core separation comes off, this is a very big bad hidden danger defective, can cause whole wiring board bad, and such manufacture method requires high to mould and machine construction when making EC type Core, mould damages frequent, and easy-formation not, the fraction defective height, processing cost is also higher.Therefore, press for a kind of production efficiency height, cost is low, does not have bad hidden danger, easily the novel inductance element of producing.
The utility model content:
The purpose of this utility model is to overcome the weak point of existing inductance element, and the inductance element of a kind of high efficiency, low cost, high-performance, small size is provided.
The utility model realizes that the technical scheme that its purpose adopts is: this inductance element comprises: hollow magnetic cover, bar magnet, coil, wherein, hollow magnetic cover is made of one piece, coil has by conductor loop around pitch of the laps portion that a fixing turn forms and the extension that is extended outward by these pitch of the laps portion two ends respectively, bar magnet is installed on vacancy in the coil, coil inserts in the inner chamber of hollow magnetic cover, and is fixed on the hollow magnetic cover by the extension of coil.
In the technique scheme, the outer wall of described hollow magnetic cover forms a fluting at least.
In the technique scheme, the last outer wall of described hollow magnetic cover or following outer wall form a fluting at least.
In the technique scheme, described coil is formed by the round conductor coiling.
Or in the technique scheme, described coil is formed by the flat wire coiling.
In the technique scheme, described hollow magnetic cover, bar magnet adopt identical soft magnetic material to be made.
Or in the technique scheme, described hollow magnetic cover, bar magnet adopt different soft magnetic materials to be made.
After adopting said structure, the utlity model has following advantage:
1,,, do not need the mould bases of two types so mould structure is simpler than EC type with mould bases and machine construction when making hollow magnetic cover moulding because hollow magnetic cover simple in structure.Therefore hollow magnetic cover production cost is low, the production efficiency height; And the structure of hollow magnetic cover is more than the mechanical strength height of original the sort of EC type.
2, the utility model does not need anchor clamps to remove fixation hollow magnetic cover and bar magnet when making up, the inductance air gap of also not worrying expanding of fixing glue and bring when baking strengthens, thereby improve the performance and the application efficiency of whole inductance element greatly, worry the not firm of fixing glue in the time of can also avoiding inductance to carry out high temperature reflux in the circuit board and produce the bad hidden danger that separates with the I type as the EC type, allow the user feel more relieved.
