CN203850120U - Transformer bobbin - Google Patents

Abstract

The utility model discloses a transformer bobbin comprising a first bobbin body and a second bobbin body. The first bobbin body comprises a hollow rectangular magnetic core column, an upper face plate and a lower face plate, a winding groove is formed among the upper face plate, the lower face plate and the magnetic core column, and a groove for accommodating a temperature detector is formed in the outer wall of the winding groove. The second bobbin body is in the same shape as the first bobbin body, and a lower face plate of the second bobbin body is attached to the lower face plate of the first bobbin body. The transformer bobbin has the advantages that being of a split structure, the transformer bobbin is more flexible to use; through the design of wire passing openings and winding posts, winding is enabled to be more convenient and rapid to carry out; a space for holding the temperature detector is added, so that safety coefficient of the transformer bobbin is heightened.

Description

A kind of transformer framework

Technical field

The utility model relates to a kind of transformer framework.

Background technology

Transformer framework is the agent structure part of transformer.Transformer is widely used at society, and corresponding main body is also essential, so skeleton has irreplaceable effect.The effect of skeleton in transformer mainly contain following some:

1, the space of winding is provided for the copper cash in transformer,

2, the magnetic core in stationary transformer.

The path of line was provided when 3, the wire casing in skeleton winds the line for transformer production.

4, the pillar that the copper cash that the metal stitch in skeleton is transformer is wound around; After scolding tin, be connected with pcb board, in the time that transformer is worked, play the effect of conduction.

5, the salient point in skeleton, concave point or chamfering, placement direction or stitch order can determine transformer use time.

Existing transformer framework, often single volume is larger, uses underaction, and coiling is convenient not.

Utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of transformer framework

For realizing this technical purpose, the scheme that the utility model adopts is:

A kind of transformer framework, comprise the first skeleton, the first skeleton comprises hollow rectangle core post, core post upper surface is provided with rectangle nosing, forms top panel, on relative two limits of top panel, symmetrical be respectively provided with two and cross line mouths, it is tubaeform crossing line mouth, uncovered outside, and line mouth is provided with the parallel line groove excessively of some circles on thickness direction excessively; On top panel, each slot end top place of crossing line mouth is provided with a L shaped wrapping post, and two wrapping posts on same limit are oppositely arranged;

Core post lower surface is also provided with rectangle nosing, forms lower panel, and the lower surface of lower panel is plane;

It between top panel, lower panel and core post, is winding slot;

Winding slot outer wall is provided with the groove of accommodating temperature-detecting device, and groove top is provided with cable-through hole, and cable-through hole is upwards through to top panel surface, between cable-through hole and top panel edge, has crossed beam trunking;

Also comprise second skeleton identical with the first frame configuration, the lower panel laminating of the lower panel of the second skeleton and the first skeleton.

The beneficial effects of the utility model are, adopt separate type, use more flexible; Cross the design of line mouth and wrapping post simultaneously, make to wind the line more convenient; Set up the space of putting temperature-detecting device, the coefficient of safety that strengthened product.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.

A kind of transformer framework, comprise the first skeleton 1, the first skeleton comprises hollow rectangle core post 11, core post upper surface is provided with rectangle nosing, forms top panel 12, on relative two limits of top panel, symmetrical be respectively provided with two and cross line mouths 13, it is tubaeform crossing line mouth, uncovered outside, and line mouth is provided with the parallel line groove 14 excessively of some circles on thickness direction excessively; On top panel, each slot end top place of crossing line mouth is provided with a L shaped wrapping post 15, and two wrapping posts on same limit are oppositely arranged;

Core post lower surface is also provided with rectangle nosing, forms lower panel 16, and the lower surface of lower panel is plane;

It between top panel, lower panel and core post, is winding slot 17;

Winding slot outer wall is provided with the groove 18 of accommodating temperature-detecting device, and groove top is provided with cable-through hole 19, and cable-through hole is upwards through to top panel surface, between cable-through hole and top panel edge, has crossed beam trunking.Temperature-detecting device is positioned in groove, can more presses close to coil, Accurate Measurement coil temperature.The cable-through hole and the crossed beam trunking that arrange for temperature-detecting device specially can make the sense line of temperature-detecting device avoid being subject to the impact of solenoid as far as possible.

Also comprise second lower panel of skeleton 2, the second skeletons identical with the first frame configuration and the laminating of the lower panel of the first skeleton, form a transformer framework completing.

When use, coil, from wrapping post, by crossing line mouth, then detours on winding slot, after some circles, then by opposite side or homonymy cross line mouth and winding slot, complete coiling, then remove wrapping post, by two skeletons laminatings.

The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle amendment that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection range of technical solutions of the utility model.
