Description

Technical Field

[0001] The utility model belongs to the technical field of transformers, and in particular relates to a multifunctional transformer coil skeleton. Background Art

[0002] The transformer coil bobbin is an important component that supports the coil winding and insulation. It is required to have good insulation performance, support strength, heat dissipation and convenient tapping function. Transformer voltage is usually customized according to user needs. Products of the same capacity may have different voltages, currents and winding wire diameters. Figure 1 As shown, existing transformer coil bobbins typically only have slotted openings on both sides of the end plate at one end. This fixed arrangement of outlet holes clearly cannot accommodate the various voltage and current requirements for transformer coils. Therefore, a multifunctional transformer coil bobbin is needed to meet the requirements for transformer coils under different voltage and current conditions. Summary of the Invention

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a multifunctional transformer coil skeleton.

[0004] The above technical problems of the present invention are mainly solved by the following technical solutions: a multifunctional transformer coil bobbin, comprising a hollow core column, an upper end panel being provided at the upper end of the hollow core column, and a lower end panel being provided at the lower end of the hollow core column, wire outlet holes being provided on both sides of the upper end panel, and the wire outlet holes on both sides are oblong holes, or the wire outlet hole on one side is an open slot-shaped hole and the wire outlet hole on the other side is an oblong hole, and wire outlet holes are also provided on both sides of the lower end panel, and the wire outlet holes on both sides are open slot-shaped holes.

[0005] Preferably, a support beam is provided on the bottom surface of the upper end panel and the lower end panel near the wire outlet hole, and reinforcing ribs are provided on both sides of the wire outlet hole. The reinforcing ribs connect the support beam and the upper end panel or the lower end panel into one, and the reinforcing ribs are in the form of a long right triangle to ensure reliable strength.

[0006] The utility model has two structural forms.

[0007] The first structural form is that wire outlet holes are provided on both sides of the upper end panel, and the wire outlet holes on both sides are oblong holes. Wire outlet holes are also provided on both sides of the lower end panel, and the wire outlet holes on both sides are open slot-shaped holes.

[0008] The second structural form is that wire outlet holes are provided on both sides of the upper end panel, wherein the wire outlet hole on one side is an open slot-shaped hole, and the wire outlet hole on the other side is an oblong hole. Wire outlet holes are also provided on both sides of the lower end panel, and the wire outlet holes on both sides are open slot-shaped holes.

[0009] The utility model has multiple usage modes.

[0010] When both the input side and the output side have low current, the utility model can be used as a conventional transformer coil skeleton. The slot-shaped holes opened on both sides of the lower end panel are used for winding and tapping. A thin-diameter wire is wound on the skeleton to form a transformer coil. The open slot-shaped holes facilitate machine winding and tapping.

[0011] When both the input side and the output side have large currents, the present invention needs to adopt the first structural form, utilizing the oblong holes on both sides of the upper panel for winding and tapping, and using thick-diameter wires or flat wires to wind the transformer coil on the skeleton. When using the terminal blocks for wiring, the thick-diameter wires or flat wires need to be bent on the oblong holes. The closed oblong holes can provide support for the thick-diameter wires or flat wires to prevent deformation of the transformer coil.

[0012] When the input side is a small current and the output side is a large current, the utility model needs to adopt the second structural form, using the slot-shaped hole opened on one side of the upper end panel for winding and tapping, and using a thin-diameter wire to be wound on the skeleton to form the input side coil. The open slot-shaped hole facilitates machine winding and tapping; using the oblong hole on the other side of the upper end panel for winding and tapping, using a thick-diameter wire or a flat wire to be wound on the skeleton to form the output side coil. When using the wiring terminal for wiring, the thick-diameter wire or the flat wire needs to be bent on the oblong hole. The closed oblong hole can provide support for the thick-diameter wire or the flat wire to prevent deformation of the transformer coil.

[0013] During assembly, first use the corresponding wire to wind the transformer coil on the frame according to the use requirements of the transformer coil under different voltage and current conditions, and perform vacuum insulation varnish dipping treatment on the transformer coil assembly. Then, insert the iron core into the hollow core column, install the upper and lower iron yokes on the iron core, and install the terminal blocks on the upper iron yoke to assemble the transformer.

[0014] This utility model improves upon existing transformer coil bobbins, providing two structural forms and multiple usage modes to meet the requirements for transformer coil usage under different voltage and current conditions. Furthermore, when the transformer coil assembly undergoes vacuum insulation varnish dipping, the wire outlet holes on either side of the upper or lower panel facilitate paint dripping and heat dissipation. Therefore, this utility model features a simple structure and a reasonable design. BRIEF DESCRIPTION OF THE DRAWINGS
