Description
Technical field
The utility model relates to a kind of inductance, relates in particular to the adjustable small inductance of a kind of inductance value.
Background technology
The central role of inductance is the variation that stops electric current, in the ascending process of electric current, all there is one " hysteresis " effect in inductor, it can resist this variation within a certain period of time, thereby forms certain resistance about galvanic variation in carving in short-term; " perfectly straight resistance friendship " characteristic of inductance, is allowed to condition in circuit and can brings into play huge effect.In board, inductance is used in several aspects such as energy storage, filtering, delay and vibration more, be to ensure that board is stable, the critical elements of safe operation, nowadays most of large-scale inductance all have the function of adjusting inductance, and the small inductance that still can carry out inductance value adjusting is still less.
Utility model content
The small inductance that provides a kind of inductance value adjustable in order to address the above problem is just provided the purpose of this utility model.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The small inductance that a kind of inductance value is adjustable, comprise shell, be arranged on the magnetic core and the first binding post and the second binding post that are arranged on described shell two ends of described enclosure, the junction of described the first binding post and described shell is provided with coupling bar, on described coupling bar, be provided with tapped through hole, in described magnetic core, be provided with blind hole, described the first binding post is fixedly connected with described coupling bar by described tapped through hole, and one end of described the first binding post is stretched in the blind hole of described magnetic core, between described magnetic core and described shell, be provided with cavity, in described cavity, be provided with and be wrapped in the copper cash in described magnetic core outside and the two ends of described copper cash are connected with described the second binding post and described coupling bar respectively.
Particularly, described the first binding post is made up of three parts, the Part I that is arranged on described housing exterior is zinc-plated high strength copper alloy conductor wire, and described Part I arranged outside has the external screw thread engaging with the tapped through hole of described coupling bar, the Part III that is arranged on described magnetic core inside is ferrimagnet core body, and the Part II that connects described Part I and described Part III is insulating material core body.
Further, described the first binding post is multiple, and the permeability of the Part III of multiple described the first binding posts is all not identical.
In the time need to regulating the inductance value of inductance, by rotating the Part I of the first binding post, its Part III is taken out from magnetic core, then change the first binding post of corresponding permeability, reach the object of adjusting inductance.
The beneficial effects of the utility model are:
The small inductance that the utility model inductance value is adjustable, by using dismountable the first binding post that has the different permeabilities of different model, reaches the inductance value object that regulates small inductance, easy to adjust, good stability.
Brief description of the drawings
Fig. 1 is the overall structure schematic diagram of the adjustable small inductance of the utility model inductance value;
Fig. 2 is the cutaway view of the adjustable small inductance of the utility model inductance value.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the small inductance that the utility model inductance value is adjustable, comprise shell 1, be arranged on the magnetic core 6 and the first binding post 3 and the second binding post 4 that are arranged on shell 1 two ends of shell 1 inside, the first binding post 3 is provided with coupling bar 2 with the junction of shell 1, on coupling bar 2, be provided with tapped through hole, in magnetic core 6, be provided with blind hole, the first binding post 3 is fixedly connected with coupling bar 2 by tapped through hole, and one end of the first binding post 3 is stretched in the blind hole of magnetic core 6, between magnetic core 6 and shell 1, be provided with cavity 5, in cavity 5, be provided with and be wrapped in the copper cash (not shown in FIG.) in magnetic core 6 outsides and the two ends of copper cash are connected with the second binding post 4 and coupling bar 2 respectively, the first binding post 3 is made up of three parts, the Part I 31 that is arranged on shell 1 outside is zinc-plated high strength copper alloy conductor wire, and Part I 31 arranged outside have the external screw thread engaging with the tapped through hole of coupling bar 2, the Part III 33 that is arranged on magnetic core 6 inside is ferrimagnet core body, connecting Part I 31 is insulating material core body with the Part II 32 of Part III 33, the first binding post 3 is multiple, the permeability of the Part III 33 of multiple the first binding posts 3 is all not identical.
The operation principle of the small inductance that the utility model inductance value is adjustable is as follows:
In the time need to regulating the inductance value of inductance, first rotate the Part I 31 of the first binding post 3, make its whiz coupling bar 2, then it is extracted out from shell 1, choose again the first binding post 3 of suitable permeability, then screwed in coupling bar 2, reach the object of adjusting inductance; Positron is by the Part I 31 of the first binding post 3, then by coupling bar 2, the first end that enters the copper cash in the shell 1 being connected with coupling bar 2 connects, finally by the second binding post 4 being connected with the second end of copper cash, the whole inductance of both having flowed through.
