Abstract

The utility model relates to an inductance, including two or two above magnetic cores, set up and be in winding, setting on the magnetic core are in last insulation board, the setting of magnetic core upper end are in the lower insulation board of magnetic core lower extreme, it is fixed go up the insulation board with the screw rod of lower insulation board, go up be equipped with on the insulation board with screw rod complex through -hole, be equipped with on the insulation board down with screw rod complex counter sink. The utility model discloses the insulation board adopts the counter sink down for the screw rod does not stretch out insulation board down, thereby has reduced inductance's focus, makes whole inductance bottom and plane contact, and the focus is more steady.

Description

A kind of inductance
Technical field
The utility model belongs to electric elements field, relates to a kind of inductance.
Background technology
Inductance has very important effect in electric elements, traditional inductance, monoblock one same dielectric plate is adopted to cover magnetic core up and down, upper lower insulation plate respectively opens the round tube hole of same diameter, is convenient to screw rod like this and fixes whole inductance through insulation board, but in installation process, easily make screw rod extension elongation different, inductance center of gravity increases, thus causes bottom inductance uneven, makes inductance unstable.
Utility model content
For the deficiencies in the prior art, the utility model aims to provide a kind of reduction inductance center of gravity, and can make bottom whole inductance and plane contact, center of gravity is more steady.
Of the present utility modelly to be achieved through the following technical solutions.
A kind of inductance, comprise two or more magnetic cores, the screw rod of the winding be arranged on described magnetic core, the upper insulation plate being arranged on described magnetic core upper end, the lower insulation plate being arranged on described magnetic core lower end, fixing described upper insulation plate and described lower insulation plate, described upper insulation plate is provided with the through hole coordinated with described screw rod, and described lower insulation plate is provided with the counter sink coordinated with described screw rod.
Preferably, the diameter of described through hole is M12, and described counter sink is " Y " font counter sink of M13-1.
Compared with prior art, the utility model has the advantages that: the utility model lower insulation plate adopts counter sink, and make screw rod not stretch out lower insulation plate, thus reduce the center of gravity of inductance, make bottom whole inductance and plane contact, center of gravity is more steady.
Accompanying drawing explanation
Fig. 1 is stereogram of the present utility model;
In figure: 1. magnetic core, 2. winding, 3. upper insulation plate, 4. lower insulation plate, 5. screw rod, 6. through hole, 7. counter sink.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
As shown in Figure 1, a kind of inductance, comprise two or more magnetic cores 1, the screw rod 5 of the winding 2 be arranged on described magnetic core 1, the upper insulation plate 3 being arranged on described magnetic core 1 upper end, the lower insulation plate 4 being arranged on described magnetic core 1 lower end, fixing described upper insulation plate 3 and described lower insulation plate 4, described upper insulation plate 3 is provided with the through hole 6 coordinated with described screw rod 5, the diameter of described through hole 6 is M12, described lower insulation plate 4 is provided with the through hole 7 coordinated with described screw rod 5, and described through hole 7 is " Y " font through hole 7 of M13-1.
The foregoing is only the utility model preferred embodiment; not thereby execution mode of the present utility model and protection range is limited; to those skilled in the art; should recognize and all should be included in the scheme that equivalent replacement done by all utilization the utility model specifications and diagramatic content and apparent change obtain in protection range of the present utility model.

Claims (2)
