Abstract
The utility model relates to a magnetism apparatus, especially relates to an annular iron-core assembly, which is composed of an annular shell, an annular iron-core positioned in the shell, wherein the said annular shell is an insulator. The annular shell is composed of an annular groove shell and a close cover, wherein the height of the groove shape internal cavity for the annular groove shell is a little larger than the height of the iron-core, the inner diameter is a little smaller than the annular cavity of the iron-core inner diameter, while the outer diameter of the close cover is the same to that of the annular groove shape shell, with the inner diameter the same to that of the annular groove shape shell. The close cover is covered on the annular cavity and fixed with the annular groove shape shell into an integer, and the annular iron-core is namely arranged in the annular cavity. The utility model saves the insulation belt for the external insulation wrapped on the aluminum annular shell in the existing technique, saves the material cost, meanwhile saves a working procedure, reduces the cost. The annular shell adopts the annular groove shape shell and the close cover and reduces the cost.
Description
(1) technical field:
The utility model relates to a kind of magnetic device, especially relates to a kind of ring structure iron core assembly.
(2) background technology:
The ring structure iron core assembly is to use the most general a kind of core assembly, can be used in the transducer of zero sequence current mutual inductor, high precision current transformer, voltage transformer, various inductance, medium-high frequency ring-shaped transformer, inductance and various power conversion of earth leakage protective shape.The magnetic circuit closure of ring structure iron core can only the punching coiling.In the prior art, the ring structure iron core assembly, particularly diameter is bigger, by the ring-like housing of aluminum, be arranged in the ring structure iron core of housing and be wound in the outer insulating tape of the ring-like housing of aluminum and form, in the said structure, the ring-like housing of aluminum is formed by the annular groove shape aluminum hull make-up of two symmetries, the height of each annular groove shape aluminum hull is half of iron core height, ring structure iron core can adopt ferrite, the thin silicon steel, materials such as iron nickel permalloy, forming behind the annular groove shape aluminum hull make-up of above-mentioned two symmetries highly is the iron core height, external diameter is slightly larger than the iron core external diameter, internal diameter is slightly less than the ring cavity of iron core internal diameter, and ring structure iron core promptly places in this ring cavity.The deficiencies in the prior art part is its cost height.
(3) summary of the invention:
The utility model aims to provide a kind of lower-cost ring structure iron core assembly.
Technical solution of the present utility model is as follows:
A kind of ring structure iron core assembly is made up of ring-like housing, the ring structure iron core that is arranged in housing, and described ring-like housing is an insulator.
The utility model is owing to adopt technique scheme, and ring-like housing itself is insulator, has saved to be wound in the ring-like housing of aluminum in the prior art and to be used to the insulating tape that insulate outward, has saved material cost, has saved one procedure simultaneously, has reduced production cost.
Further technical scheme is:
Described ring-like housing is made up of an annular groove shape housing and a capping, it highly is slightly larger than the groove shape inner chamber of above-mentioned annular groove shape housing iron core height, external diameter and is slightly larger than the ring cavity that iron core external diameter, internal diameter are slightly less than the iron core internal diameter, the external diameter of capping is identical with the external diameter of annular groove shape housing, its internal diameter is identical with the internal diameter of annular groove shape housing, capping is covered on the ring cavity, and be fixed as one with annular groove shape housing, ring structure iron core promptly places in this ring cavity.
The total cost of production of annular groove shape housing and capping is lower than the total cost of production of the annular groove shape aluminum hull of two symmetries in this technical scheme.
Further improvements are again:
Described groove shape housing and capping are made by the resin that is built-in with glass, and this scheme helps to guarantee the intensity of ring-like housing.
(4) description of drawings:
Below with reference to drawings and Examples the utility model is described in further details:
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Each sequence number is respectively in the accompanying drawing 1: 1, annular groove shape housing; 2, capping; 3, iron core; 4, glass; 5, resin
(5) embodiment:
Referring to accompanying drawing 1, among the utility model embodiment, the ring structure iron core assembly is by annular groove shape housing 1, be arranged in the ring structure iron core 2 of housing, capping 3 is formed, described groove shape housing and capping are made by the resin 5 that is built-in with glass 4, it highly is slightly larger than iron core 3 height the groove shape inner chamber of above-mentioned annular groove shape housing, external diameter is slightly larger than the iron core external diameter, internal diameter is slightly less than the ring cavity of iron core internal diameter, ring structure iron core promptly places in this ring cavity, the external diameter of capping is identical with the external diameter of annular groove shape housing, its internal diameter is identical with the internal diameter of annular groove shape housing, capping is covered on the ring cavity, and is fixed as one with annular groove shape housing.
The utility model has been saved material cost owing to adopt technique scheme, has reduced production cost simultaneously.
Certainly, under inventive concept of the present utility model, the utility model has multiple form of implementation, as, groove shape housing and capping can be made by other insulating material, and those skilled in the art read and need not pay creative work behind this specification and can reveal again, have not just described in detail at this.
Claims (3)
1, a kind of ring structure iron core assembly is made up of ring-like housing, the ring structure iron core that is arranged in housing, and described ring-like housing is an insulator.
2, ring structure iron core assembly according to claim 1, it is characterized in that: described ring-like housing is made up of an annular groove shape housing and a capping, it highly is slightly larger than the groove shape inner chamber of above-mentioned annular groove shape housing iron core height, external diameter and is slightly larger than the ring cavity that iron core external diameter, internal diameter are slightly less than the iron core internal diameter, the external diameter of capping is identical with the external diameter of annular groove shape housing, its internal diameter is identical with the internal diameter of annular groove shape housing, capping is covered on the ring cavity, and be fixed as one with annular groove shape housing, ring structure iron core promptly places in this ring cavity.
