Abstract
The utility model discloses a coil skeleton, which comprises a winding part which is in hollow column form. The utility model is characterized in that the winding part is also provided with an isolating convex ring which is arranged on an air gap which is relatively arranged between magnetic core center columns. The isolating convex ring is designed into an intrinsic structure of the coil skeleton, the size is easy to control, the coiling accuracy is easy to control and can not deform or slide, and therefore, the power consumption of the coil can be effectively lowered; The isolating convex ring is provided with one or a plurality of crossing grooves, which makes the winding compact and smooth when the winding is wound from one side of the isolating convex ring to the other side of the isolating convex ring.
Description
The utility model relates to a kind of coil rack structure, the particularly coil rack of inductance, transformer.
Existing coil rack winding portion is level and smooth open tubular column.Usually, when design high-frequency inductor, transformer, enter saturation condition, damage circuit, usually can leave a certain amount of air gap between the core center post for preventing magnetic core.But when magnetic flux passes air gap, because the magnetic resistance of air gap is much larger than the magnetic resistance of magnetic core, thus higher relatively at air gap and temperature on every side thereof, influence near the coil air gap, the efficient of reduction inductance, transformer; Simultaneously,, when leakage flux is passed wire coil on skeleton, can produce eddy current effect, the local coil temperature is raise and increase power loss because air gap periphery can produce leakage flux.For addressing this problem, on the coil rack with respect to the position of air gap around on the insulation filling band of certain width and thickness, but, do having many shortcomings like this because the insulation filling band adopts the mode that is layering around to required thickness: the one, waste time and energy, production efficiency is lower; The 2nd, width and thickness are difficult to be grasped, and makes the quality of product and difficult parameters with control; The 3rd, the insulation filling band slides easily, can not hide the air gap between magnetic core fully, does not reach the effect of isolation.
The purpose of this utility model is in order to overcome above-mentioned weak point, a kind of simple and convenient, easy-operating coil rack to be provided.
The purpose of this utility model is achieved in that coil rack, comprises the winding portion that is open column shape, it is characterized in that described winding portion also is being provided with the isolation bulge loop with respect to the air gap place between the core center post.
During the coil rack die sinking, in the middle of the level and smooth open tubular column of existing skeleton, add one to isolate bulge loop, the width of isolating bulge loop is between 2mm-6mm, height is between 1mm-3mm, concrete size is decided on skeleton and size of gaps, make and isolate the inherent structure that bulge loop becomes coil rack, not only played the buffer action of traditional insulation filling band, and, to isolate the size of bulge loop and hold easily, the precision of coiling is easy to control, more can not be out of shape and slide, therefore, the utility model can reduce the power loss of coil effectively, enhances productivity and the operating efficiency of inductance or transformer.
As further improvement of the utility model, on described isolation bulge loop, have one or several cross-line groove, make coiling compact, smooth more around to another side the time from the one side that isolates bulge loop.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation that the utility model coil rack is arranged.
The inductance generalized section of Fig. 2 for adopting the coiling of the utility model skeleton to finish.
With reference to Fig. 1, coil rack 7 is provided with on the winding portion 2 that is open column shape and isolates bulge loop 3, isolates on the bulge loop having cross-line groove 5.Isolate bulge loop and coil rack and adopt bakelite spare, and the one cast molding.
Figure 2 shows that the utility model is used as the user mode of inductance coil skeleton, two " E " type magnetic cores 6,10 penetrate from the isolation strip 1,4 of coil rack upper/lower terminal relatively, two pairs of other posts are involutory, form air gap 9 between the newel, this air gap is relative with the isolation bulge loop 3 of described coil rack winding portion.8 is coil among the figure.
Claims (2)
1, a kind of coil rack comprises the winding portion (2) that is open column shape, it is characterized in that described winding portion also is being provided with isolation bulge loop (3) with respect to the air gap place between the core center post.
2, coil rack as claimed in claim 1 is characterized in that having on the described isolation bulge loop one or several cross-line groove (5).
