Description

Technical Field

[0001] This utility model relates to Litz wire technology, specifically a Litz wire single-layer insulated stranded molding fixture. Background Technology

[0002] Litz wire, meaning a conductor composed of multiple independently insulated conductors twisted together, is called stranded wire. Stranding is achieved by rotating the stranded individual wires around a stranding axis at a constant angular velocity and by the strand moving forward at a uniform speed. Commonly used materials are copper and aluminum. Copper and aluminum wires can be stranded into conductors of various cross-sections and types of electrical wires and cables. It is suitable for applications with high operating frequencies and where single-strand wires suffer excessive losses due to skin effect and proximity effect. Using stranded wire can lower operating temperatures, and compared to single-strand wire of the same cross-sectional area, stranded wire possesses higher mechanical strength and flexibility.

[0003] However, existing Litz wire stranding fixtures can only form multiple Litz wires into round wires, but cannot form them into rectangular conductors. Therefore, there is an urgent need for a rectangular conductor stranding forming fixture. Utility Model Content

[0004] To address the shortcomings of the prior art, this invention provides a Leeds wire single-layer insulation stranding molding fixture, which can quickly strand multiple bundles of insulated wires into a rectangular conductor.

[0005] To achieve the above technical objectives, this utility model adopts the following technical solution: a Litz wire single-layer insulation stranding molding fixture, comprising an inlet section, a transition section, and a molding section. The transition section is located between the inlet section and the molding section. The inlet section is used to guide multiple wires in. A first guide section is provided between the inlet section and the transition section. The first guide section is used to guide the wires from the inlet section into the transition section. A second guide section is provided between the transition section and the molding section. The second guide section is used to guide the wires into the molding section. The molding section is used to strand the wires into a rectangular conductor.

[0006] Preferably, the cross-section of the inlet section is circular, and the inlet section has inlet holes evenly distributed around its circumference.

[0007] Preferably, the inlet section has a mounting hole at its center.

[0008] Preferably, the transition section has a transition cavity, and the cross-section of the transition cavity is elliptical.

[0009] Preferably, the molding part has a molding cavity, which is rectangular.

[0010] In summary, this utility model achieves the following technical effects:

[0011] The Litz wire single-layer insulated stranding molding fixture of this utility model adopts a first guide part and a transition part, which can quickly guide multiple bundles of insulated wires into elliptical conductors, and in conjunction with a second guide part and a molding part, mold the elliptical conductors into rectangular conductors.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0022] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0023] Example 1:

[0024] like Figure 1 As shown, a Leeds wire single-layer insulation stranding molding fixture includes an inlet section 1, a transition section 3, and a molding section 5. The transition section 3 is located between the inlet section 1 and the molding section 5. The inlet section 1 is used to guide multiple wires 9 into the inlet. A first guide section 2 is provided between the inlet section 1 and the transition section 3. The first guide section 2 is used to guide the wires 9 from the inlet section 1 into the transition section 3. A second guide section 4 is provided between the transition section 3 and the molding section 5. The second guide section 4 is used to guide the wires into the molding section 5. The molding section 5 is used to strand the wires 9 into a rectangular conductor.

[0025] Multiple bundles of wires 9 enter the wire inlet section 1 sequentially through the wire inlet hole 6. The wire inlet section 1 is installed on the machine or forming equipment through the mounting hole. The wires 9 are guided by the first guide section 2 and converge inward before entering the transition section 3. Since the transition cavity 7 is elliptical, the wires 9 in the short half-axis direction of the transition cavity 7 are squeezed inward, while the wires in the long half-axis direction of the transition cavity 7 remain stable or move slightly inward, forming an elliptical conductor. Then, guided by the second guide section 4, the wires enter the forming cavity 8, are squeezed to form a rectangular conductor, and are then discharged.

[0026] The Litz wire single-layer insulated stranding molding fixture of this embodiment uses a first guide part 2 and a transition part 3 to quickly guide multiple bundles of insulated wires into elliptical conductors, and works with a second guide part 4 and a molding part 5 to mold the elliptical conductors into rectangular conductors.

[0027] like Figure 2 As shown, the cross-section of the wire inlet 1 is circular, and the wire inlet 1 has wire inlet holes 6 evenly distributed around its circumference.

[0028] like Figure 3 As shown, the transition section 3 is provided with a transition cavity 7, and the cross-section of the transition cavity 7 is elliptical.

[0029] like Figure 4 As shown, the molding part 5 has a molding cavity 8, which is rectangular.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
