Abstract
The utility model discloses a low-voltage coil outlet head which comprises a pressing plate. A bar-shaped groove is formed in the inner side of the pressing plate. A low-voltage coil is arranged in the bar-shaped groove and comprises a plurality of wires which are horizontally and spirally wound in a parallel mode. The wires close to the inner diameter side of the coil are perpendicular to the wires close to the outer diameter side of the coil. The low-voltage coil head is reasonable and simple in structure, and the wires which are horizontally and spirally made in the parallel mode are fixed through the bar-shaped groove of the inner side of the pressing plate. The structure is firm and reliable, the thickness of the pressing plate is reduced, the height of the pressing plate is reduced, using of raw materials is saved, stress of the pressing plate is larger, damage is not prone to happening, and service life is quite long.

Technical field
The utility model relates to field transformer, particularly relates to a kind of low-voltage coil for transformer and lifts one's head.
Background technology
It is all to offer a low-voltage coil wire hole on pressing plate that existing low-voltage coil for transformer is lifted one's head, and low-voltage coil passes wire hole, can be fixed low-voltage coil.Yet generally offer the rectangle wire hole on existing pressing plate, because the size in hole is larger, the pressing plate wall is stressed less, when low-voltage coil passes wire hole, and the pressing plate cracky, thus the necessary larger pressing plate of used thickness has been wasted raw-material use greatly.
The utility model content
The technical problem that the utility model mainly solves is to provide a kind of simple in structure, reasonable in design, solid and reliable, stressed larger, low-voltage coil economical with materials and lifts one's head.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of low-voltage coil to lift one's head, comprise pressing plate, described pressing plate inboard offers strip groove, be provided with low-voltage coil in described strip groove, described low-voltage coil comprises the wire of some horizontal side-by-side helix coilings, by wire and vertical setting of wire of leaning on the coil outer diameter side of internal coil diameter side.
In preferred embodiment of the utility model, described wire is provided with the wrapping layer outward.
In preferred embodiment of the utility model, described two circle wires and vertical setting of wire of leaning on the coil outer diameter side by the internal coil diameter side.
In preferred embodiment of the utility model, described wire by the internal coil diameter side is provided with square ring with leaning between the wire of coil outer diameter side.
In preferred embodiment of the utility model, evenly be fixed with some cushion blocks on described pressing plate.
In preferred embodiment of the utility model, described cushion block and pressing plate adhesion.
In preferred embodiment of the utility model, described pressing plate surrounding offers some installing holes.
The beneficial effects of the utility model are: the utility model low-voltage coil is lifted one's head reasonable in design simple, the wire of horizontal side-by-side helix coiling is fixed by the strip groove of pressing plate inboard, sound construction is reliable, reduced the thickness of pressing plate, reduced the height of pressing plate, saved raw-material use, pressing plate is stressed larger, cracky not, useful life is longer.
Description of drawings

In accompanying drawing, the mark of each parts is as follows: 1, pressing plate, 2, bar shaped, 3, cushion block, 4, by the wire of coil outer diameter side, 5, by the wire of internal coil diameter side, 6, the wrapping layer, 7, square ring, 8, installing hole.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection range of the present utility model is made more explicit defining.
See also Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of low-voltage coil is lifted one's head, comprise pressing plate 1, described pressing plate 1 inboard offers strip groove 2, is provided with low-voltage coil in described strip groove 2, described low-voltage coil comprises the wire of some horizontal side-by-side helix coilings, by wire 5 and the vertical setting of wire 4 of leaning on the coil outer diameter side of internal coil diameter side.
Described wire is provided with wrapping layer 6 outward, wires for bundling can be integral, and prevents that conductor wiring is loose, and sound construction is reliable.Wrapping layer 6 is selected cloth, and cost is lower, and wrapping is convenient.
Described wire is 28, and conductor cross-section is rectangular, and two circle wires 5 and the vertical setting of wire 4 of leaning on the coil outer diameter side by the internal coil diameter side make the end of wrapping layer 6 form chamfering, and when preventing from installing, low-voltage coil is stuck in strip groove 2.
Described wire 5 by the internal coil diameter side is provided with square ring 7 with leaning between the wire 4 of coil outer diameter side, square ring 7 plays the effect of support, can prevent by the wire 5 of internal coil diameter side and be shifted by between the wire 4 of coil outer diameter side, making structure more firmly stable.
As shown in Figure 3, evenly be fixed with some cushion blocks 3 on described pressing plate 1, described cushion block 3 and pressing plate 1 adhesion, cushion block 3 has facilitated the installation and removal of this pressing plate 1.
Described pressing plate 1 surrounding offers some installing holes 8, is used for this pressing plate 1 of fixed installation.
During installation, 28 wires are along insulating cylinder excircle level screw winding to the right side by side, after coiling one circle, directly upwards bending of 26 wires 4 by the coil outer diameter side, two upwards bendings of circle wire 5 by the internal coil diameter side, and along the axis 90-degree rotation, make by two circle wires 5 of internal coil diameter side vertical with the wire 4 that leans on the coil outer diameter side, then in 6 wrapping of 28 wire external application wrapping layers, form the low-voltage coil of strip, by pressing plate 1, low-voltage coil is fixed, low-voltage coil passes the strip groove 2 of pressing plate 1 inboard, completes installation.
Compared with prior art, the utility model low-voltage coil is lifted one's head reasonable in design simple, the wire of horizontal side-by-side helix coiling is fixing by the strip groove 2 of pressing plate 1 inboard, sound construction is reliable, has reduced the thickness of pressing plate 1, has reduced the height of pressing plate 1, saved raw-material use, pressing plate 1 is stressed larger, cracky not, and useful life is longer.
The above is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
