Description
Technical field
It the utility model is related to the core component on a kind of permanent-magnet breaker.
Background technology
Permanent-magnet breaker uses in bistable state and sets device for under-voltage releasing equipment permanent magnet mechanism, and is became one with mechanical, hand-driven electrical apparatus release
Change design, make manual brake separating light reliable；Permanent magnet mechanism separating brake is combined with spring separating brake, the distribution of opening velocity is more managed
Think；Compared with operating machine of the spring mechanism circuit-breaker, movable member greatly reduces, and greatly improves its reliability and mechanical life, is
The preferable substitute products of spring operating mechanism type breaker.
Core component in permanent-magnet breaker makes the core component of whole permanent-magnet breaker, but core body group on the market at present
The shortcomings that part generally existing is complicated, mechanical strength is not high, do not grown thereby using the life-span.
To problem above, it is badly in need of us and solves.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of insulation effect is good, high mechanical strength
With the core component on the permanent-magnet breaker of service life length.
In order to achieve the above object, the core component on a kind of permanent-magnet breaker designed by the utility model, it includes
Sleeve body and iron core, sleeve body are made up of glass fiber material, and sleeve body is hollow by the straight tube of a hollow structure and one
Structure and aperture is formed by connecting in up-small and down-big conical pipe, is provided with two through holes, and two on the outer circumference surface of sleeve body
The central axis of individual through hole overlaps；Iron core is in cylindrical structure, and the diameter of iron core is engaged with the internal diameter of sleeve body, so as to
Iron core is set to be arranged on the inside of sleeve body；Two No.1 contacts, two No.1 contacts are provided with the outer circumference surface of iron core
Central axis overlap, and the shape of two No.1 contacts is identical with the shape of through holes in sleeve body, the external diameter of No.1 contact
With the apertures of through hole, so that No.1 contact can run through through hole and be arranged on through hole, and also set in the upper surface of iron core
There are No. two contacts.
In order that easy for installation and conductive effect is more preferable, the length of No.1 contact is identical with the wall thickness of sleeve body, so as to
Make the end face of No.1 contact concordant with the lateral wall of sleeve body；Certainly, the length of No.1 contact can also be more than sleeve body
Wall thickness so that through hole of the No.1 contact in the sleeve body and being exposed at outside through hole.
In order to easy to process, through hole in sleeve body is rounded, oval, regular hexagon or rectangular configuration.
In order to easy to process, shape, the size of No. two contacts are identical with shape, the size of No.1 contact, and No. two contacts
It is arranged on the centre position of iron core upper surface.
In accordance with the above, the core component on a kind of permanent-magnet breaker designed by the utility model, passes through the uniqueness
Structure design so that be well positioned to meet mechanical strength during use, and service life is grown, insulation effect might as well.Therefore, it
Have the characteristics that simple in construction, easy to use and reasonable in design.
Brief description of the drawings
Fig. 1 is complete section front view of the present utility model；
Fig. 2 is the structural representation of iron core.
Embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the core component on a kind of permanent-magnet breaker of the present embodiment description, it includes sleeve body
1 and iron core 2, sleeve body 1 be made up of glass fiber material, sleeve body 1 by a hollow structure straight tube and a hollow structure
And aperture is formed by connecting in up-small and down-big conical pipe, two through holes are provided with the outer circumference surface of sleeve body 1, and two logical
The central axis in hole overlaps；Iron core 2 is in cylindrical structure, and the diameter of iron core 2 is engaged with the internal diameter of sleeve body 1, in iron
The outer circumference surface of core 2 is provided with two No.1 contacts 3, and the central axis of two No.1 contacts 3 overlaps, and two No.1 contacts 3
Shape it is identical with the shape of through holes in sleeve body 1, the external diameter of No.1 contact 3 and the apertures of through hole, so that No.1
Contact 3 can run through through hole and be exposed at outside through hole, and No. two contacts 4 are additionally provided with the upper surface of iron core 2.
