Abstract
The utility model discloses an inductance coil structure which comprises an installation skeleton and a coil. The section of the installation skeleton is of a cross shape, and the coil is winded on the installation skeleton in turn-by-turn mode. By means of the structure, the inductance coil structure has the advantages that permeability is achieved inside and outside, all the outer surface of the coil can dissipate heat, and good heat dissipation effect is achieved; and distributed capacitance can be effectively reduced, as media among turns of the coil utilize air to replace paper pipes, nylon, epoxy glass cloth pipes, and the like, dielectric constant of the air is smaller than paper pipes, the nylon, epoxy glass cloth pipes, and the like, the distributed capacitance becomes smaller while the dielectric constant becomes smaller, the dielectric loss of the installation skeleton becomes smaller, the Q value is increased, stability becomes good, the quality of the inductance coil structure is improved and the service life of the inductance coil structure is prolonged.
Description
Technical field
The utility model relates to a kind of inductance coil structure.
Background technology
Inductance coil be by the lead from coil to coil on insulated tube, lead insulate each other, and insulated tube can be hollow, also can comprise iron core or magnetic core.Inductance coil is electric elements the most frequently used on the various circuit, and the quality of inductance quality has very big influence to the size stable, energy consumption of circuit performance.Inductance quality factor Q is a physical quantity weighing the inductance coil quality, and Q is the ratio of the inductive reactance xl resistance equivalent with it, that is: Q=XL/R.The Q value of inductance coil is higher, and the loss in loop is littler.The Q value of inductance coil and the D.C. resistance of lead, the dielectric loss of skeleton, the loss that radome or iron core cause, the factors such as influence of high frequency skin effect are relevant.The electric capacity that the circle of inductance coil and turn-to-turn exist is called as distributed capacitance.The existence of distributed capacitance reduces the Q value of coil, bad stability, thereby the distributed capacitance of coil is more little good more.At present insulated tube adopts paper web, nylon, epoxy glass fabric cannon born frame usually, because lead is directly in the skeleton helicla flute, the heat radiation of inductance coil is relatively poor, dielectric constant is also big than air, so the dielectric loss of skeleton is just big.
The utility model content
The utility model technical problem to be solved is to the deficiency of prior art, a kind of inductance coil structure that reduces the dielectric loss of skeleton to the inductance quality influence to be provided.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of inductance coil structure, and comprise skeleton and coil are installed, described installation skeleton cross section is crosswise, and described coil from coil to coil is on described installation skeleton.
Described installation skeleton comprises first supporting bracket and second supporting bracket; Be respectively equipped with a plurality of draw-in grooves on the dual-side of described first supporting bracket; Described first supporting bracket middle part is provided with kidney slot; Described second supporting bracket snaps in the described kidney slot, and the two ends of second supporting bracket snap in the kidney slot place and are provided with step-like bayonet socket, is respectively equipped with a plurality of draw-in grooves on the dual-side of second supporting bracket.
Draw-in groove on the described first supporting bracket dual-side and the draw-in groove on the second supporting bracket dual-side are for being crisscross arranged.
The two ends of described first supporting bracket are respectively equipped with through hole.
The utility model adopts said structure, and have the following advantages: penetrating 1,, coil all outer surfaces all can dispel the heat, and radiating effect is good especially; 2, can effectively reduce distributed capacitance; Because the medium of the circle of coil and turn-to-turn becomes air by paper web, nylon, expoxy glass stringing etc., the air dielectric constant is little more a lot of than above-mentioned material, and the more little distributed capacitance of dielectric constant is more little; The dielectric loss that skeleton is installed is just little; The Q value increases, and stability improves, and quality, the life-span of inductance coil are greatly improved.

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation;
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the cross section structure sketch map of the utility model;
Fig. 3 is the structural representation of first supporting bracket in the utility model;
Fig. 4 is the structural representation of second supporting bracket in the utility model;
In Fig. 1 ~ Fig. 4,1, coil; 2, first supporting bracket; 3, second supporting bracket; 4, draw-in groove; 5, kidney slot; 6, bayonet socket.
Embodiment
Like Fig. 1 ~ a kind of inductance coil structure shown in Figure 4, comprise skeleton and coil 1 be installed that the skeleton cross section is installed is crosswise, coil 1 from coil to coil is on described installation skeleton.Skeleton is installed is comprised first supporting bracket 2 and second supporting bracket 3; Be respectively equipped with a plurality of draw-in grooves 4 on the dual-side of first supporting bracket 2; First supporting bracket, 2 middle parts are provided with kidney slot 5; Second supporting bracket 3 snaps in the described kidney slot 5, and the two ends of second supporting bracket 3 snap on the dual-side that the kidney slot place is provided with step-like bayonet socket 6, the second supporting brackets and are respectively equipped with a plurality of draw-in grooves.Second supporting bracket 3 is directly inserted in the kidney slot 5 of first supporting bracket 2, and step-like bayonet socket 6 plays position-limiting action, and second supporting bracket and first supporting bracket form the skeleton of a crux.Draw-in groove on first supporting bracket, 2 dual-sides and the draw-in groove on the second supporting bracket dual-side are for being crisscross arranged.
The two ends of first supporting bracket 2 are respectively equipped with through hole; Be used for fixing coil, one that only need will wind coil is passed the curved right angle of through hole, coil from coil to coil card people is installed in the draw-in groove of skeleton; The curved right angle of aperture is also passed in the other end of coil, just can convenient, reliably assemble inductance coil; First supporting bracket, 2 two ends grow that part can be punched, tapping etc., so just can guarantee the assembling of inductance coil and other components and parts.
Because the medium of the circle of coil and turn-to-turn becomes air by paper web, nylon, expoxy glass stringing etc.; The air dielectric constant is little more a lot of than above-mentioned material; The more little distributed capacitance of dielectric constant is more little, and the dielectric loss that skeleton is installed is just little, and the Q value increases; Stability improves, and quality, the life-span of inductance coil are greatly improved.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as the various improvement of having adopted the technical scheme of the utility model to carry out; Or directly apply to other occasion without improvement, all within the protection range of the utility model.
