Abstract

The utility model discloses a transformer frame. The cross sections of wire grooves at two ends of the secondary side of the transformer frame are in a right angle ladder shape, and the inclined edges of the right angle ladder shapes are placed on the outer sides of the wire grooves. According to the transformer frame, in-and-out wires on the secondary side can slide into the wire groove inclined edge positions during winding, the distance between the secondary side and an iron core, and the high-voltage unhealthy phenomenon is avoided. In addition, according to the fact the center hole diameter of the transformer frame is shortened, the size of a transformer can be reduced, and therefore use of the wires is reduced, and the purpose of saving energy is achieved.

Description

Transformer framework

Technical field

The utility model relates to the transformer technology field, particularly a kind of transformer framework.

Background technology

Transformer framework, or claim transformer coil holder, English is referred to as Bobbin, is the agent structure part of transformer.Its effect mainly is, for the wire in the transformer provides the space of winding and the iron core in the stationary transformer.Wire casing in the skeleton provided the path of line when winding the line for transformer production.Because at present the wire casing at transformer framework primary side two ends generally is rectangle or square, as shown in Figure 1, wire inclines toward the iron core direction easily and leans on when winding the line, thereby causes the space length of transformer secondary output and iron core not enough, and then generation high pressure bad phenomenon.In addition, because there are larger space in the mesopore of transformer framework and iron core middle column, thereby cause the waste of wire rod, be unfavorable for reaching the target that economizes on resources.

Summary of the invention

(1) technical problem to be solved

The purpose of this utility model is to provide a kind of novel transformer framework, thereby easily inclines by the problem of the space length deficiency that causes secondary and iron core toward the iron core direction to solve the secondary coil that exists in the prior art.

(2) technical scheme

In order to solve the problems of the technologies described above, the utility model proposes a kind of transformer framework, the cross section of the wire casing at described transformer framework primary side two ends be shaped as right-angled trapezium, and the hypotenuse of right-angled trapezium is positioned at the outside of described wire casing.

Optionally, the bottom length of described wire casing is greater than 2.00mm.

Optionally, the bottom length of described wire casing is 2.70mm.

Optionally, described transformer framework is provided with the mesopore for accommodating iron core, and described median pore diameter is less than 14.00mm.

Optionally, the median pore diameter of described transformer framework is 13.70mm.

(3) beneficial effect

The transformer framework that employing the utility model proposes, because the wire casing at skeleton primary side two ends is at right angles trapezoidal, and the hypotenuse of right-angled trapezium places the outside of described wire casing, like this when winding the line, the line of primary side can be taken advantage of a situation and be slipped into wire casing hypotenuse position, thereby increase secondary and distance iron core, avoid producing the high pressure bad phenomenon.In addition, owing to dwindled the diameter of skeleton mesopore, so that the overall volume of transformer dwindles, thereby reduce the use of wire rod, reached the purpose that economizes on resources.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.

The utility model proposes a kind of transformer framework, the cross section of the wire casing at described transformer framework primary side two ends be shaped as right-angled trapezium, and the hypotenuse of right-angled trapezium is positioned at the outside of described wire casing, shown in Fig. 2,3.Adopt above-mentioned wire casing shape, when winding the line, the line of primary side can be taken advantage of a situation and be slipped into the hypotenuse position in the wire casing outside, thereby increases the distance of transformer secondary output and iron core.

Optionally, the bottom length of described wire casing is greater than 2.00mm.As shown in Figure 1, at present the wire casing 1 at transformer framework primary side two ends is rectangle or square usually, for example the rectangle wire casing general long for 2.00mm, wide be 1.50mm, or the general length of side of square wire casing is 2.00mm.As shown in Figure 2, in the utility model, described wire casing 1 ' shape at right angles trapezoidal, the bottom of right-angled trapezium is than upper bottom side length, the length of bottom is greater than 2.00mm.

Wherein, preferred, described wire casing 1 ' bottom length be 2.70mm.

Optionally, described transformer framework is provided with the mesopore for accommodating iron core, and described median pore diameter is less than 14.00mm.As shown in Figure 1, mesopore 2 diameters of transformer framework are generally 14.00mm at present.There is larger space in the mesopore 2 of transformer framework with iron core middle column, can cause the waste of wire rod.As shown in Figure 2, in the utility model, the mesopore 2 ' diameter of transformer framework is less than 14.00mm.Dwindling of median pore diameter can make volume of transformer dwindle, thereby reduces expending of wire rod.

Wherein, preferred, the mesopore 2 ' diameter of described transformer framework is 13.70mm.

The stereochemical structure of the transformer framework that the utility model proposes as shown in Figure 3.

The above only is preferred implementation of the present utility model; for a person skilled in the art; under the prerequisite that does not break away from the utility model know-why, can also make some improvement and replacement, these improvement and replacement also should be considered as protection range of the present utility model.
