The oblong coil also includes a first longitudinal pull strip, a first transverse pull strip, and a second longitudinal pull strip.

[0027] Reference Figure 1-7 The image shown is a preferred embodiment of the present invention.

[0028] A square insulated wire multi-strand coil includes a coil body 1 and a wire covering film 2. The coil body 1 includes multiple insulated wires 11, which are arranged in parallel. Each insulated wire 11 is formed by multiple strands of wire 111 being wound together. The wire covering film 2 wraps around the coil body 1. The coil body 1 is arranged in a square shape. The coil body 1 is wound to form a coil component 3. The coil component 3 has multiple outer ring surfaces, which are arranged in a flush and corresponding manner.

[0029] The aforementioned square insulated wire 11 multi-wire parallel-wound coil, due to the square shape of the coil body 1, increases the contact area between each insulated wire 11, and also increases the contact area between the wire-covering film 2 and each insulated wire 11, greatly enhancing the heat conduction between the coil body 1 and the coil body 1 and the wire-covering film 2, improving the high temperature resistance of the coil component 3, enabling stable operation in high temperature environments, and improving the temperature stability and service life of the coil component 3.

[0030] The wire coating 2 may be made of copper foil, or the wire coating 2 may be made of copper, or the wire coating 2 may be made of copper alloy.

[0031] The coil component 3 includes two wire parts 31 and a winding part 32. The two ends of the winding part 32 are respectively connected to the two wire parts 31 and are integrally formed. The winding part 32 is formed by winding, and the outer surface of the winding part 32 forms multiple outer ring surfaces. The winding part 32 converts electrical energy into magnetic energy for storage and releases it when needed.

[0032] The inner surface of the winding part 32 forms multiple inner ring surfaces, each inner ring surface is arranged in a flush and corresponding manner, and the inner ring surfaces and outer ring surfaces are arranged in a parallel and spaced manner; this improves the high temperature resistance of the coil component 3, enabling it to work stably in high temperature environments, and improves the temperature stability and service life of the coil component 3.

[0033] The inner surface of the winding portion 32 forms multiple top coil surfaces and multiple bottom coil surfaces, which are arranged in parallel and spaced intervals. The top coil surface, outer coil surface, bottom coil surface, and inner coil surface are arranged in a square shape and are joined together. The winding portion 32 includes multiple winding segments, each with a top coil surface, outer coil surface, bottom coil surface, and inner coil surface. The top coil surface and bottom coil surface of adjacent winding segments are arranged in an overlapping and contacting manner. This improves the high-temperature resistance of the coil component 3, enabling it to work stably in high-temperature environments and improving the temperature stability and service life of the coil component 3.

[0034] The winding part 32 is hollow in the middle and forms winding holes. The winding holes are arranged in a square shape or in a rectangular shape. This meets the usage needs of different application scenarios and is more adaptable.

[0035] The coil component 3 includes two wire sections 31, multiple winding sections 32, and multiple connecting sections 33. The two ends of the connecting sections 33 are respectively connected to the winding sections 32 and are integrally formed. The two wire sections 31 are connected at both ends, and the two wire sections 31 are respectively connected to the winding sections 32 at both ends and are integrally formed. With the cooperation of different winding sections 32, the electrical energy in multiple areas is converted into magnetic energy for storage and released when needed, meeting the usage requirements of different application scenarios. At the same time, there is enough magnetic energy for storage and release.

[0036] Implementation of winding section one:

[0037] The winding part 32 is arranged in a spring-like winding pattern; it realizes the conversion of electrical energy into magnetic energy for storage and release when needed.

[0038] Implementation of winding section two:

[0039] The winding part 32 is arranged in an α-shaped winding; electrical energy is converted into magnetic energy for storage and released when needed.

[0040] Alpha winding, where both conductors are wound from the outside of the coil to form an A-shaped or circular hole structure, can effectively reduce internal resistance and improve mutual inductance efficiency.

[0041] Example 1 of coil body:

[0042] The coil body 1 includes three insulated wires 11, which are arranged side by side and wound synchronously to form the coil body 1. The wire covering film 2 synchronously wraps the three insulated wires 11. The three insulated wires 11 work together to improve heat conduction, improve the high temperature resistance of the coil body 1, enable stable operation in high temperature environment, and improve the temperature stability and service life of the coil component 3.

[0043] The insulating wires 11 are arranged in a square shape, with three insulating wires 11 arranged side by side and stacked together. The covering film 2 wraps the three insulating wires 11 in a rectangular shape. This improves the high temperature resistance of the coil body 1, enabling it to work stably in high temperature environments and improving the temperature stability and service life of the coil components 3.

[0044] Three insulating wires 11 are arranged side by side in a rectangular pattern, and the wire covering film 2 is rectangular in shape to wrap around the three insulating wires 11, thereby increasing the contact area between the three insulating wires 11 and the wire covering film 2.

[0045] Example 2 of coil body:

[0046] The coil body 1 includes four insulated wires 11, which are arranged in pairs and wound synchronously to form the coil body 1. The covering film 2 synchronously wraps the four insulated wires 11. The four insulated wires 11 work together to improve heat conduction, improve the high temperature resistance of the coil body 1, enable stable operation in high temperature environments, and improve the temperature stability and service life of the coil component 3.

[0047] The insulating wires 11 are arranged in a square shape, and the four insulating wires 11 are arranged in a square shape. The wire covering film 2 wraps the four insulating wires 11 in a square shape. This increases the contact area between the four insulating wires 11 and the wire covering film 2, and also improves the high temperature resistance of the coil body 1, enabling it to work stably in high temperature environments and improving the temperature stability and service life of the coil component 3.

[0048] Dual-line implementation example:

[0049] The square insulated wire multi-wire winding coil includes two coil bodies 1 and two wire covering films 2. The wire covering films 2 and the coil bodies 1 are arranged in a one-to-one correspondence and wrapping arrangement. The two coil bodies 1 are arranged in a radially overlapping arrangement and are synchronously wound to form a coil component 3.

[0050] This improves the high insulation and wear resistance of coil component 3, ensures the energy conversion performance of coil component 3, and effectively extends the service life of coil component 3.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
