[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] As described in the background, coils in devices like transformers and inductors typically consist of a bobbin, windings, a magnetic core, and a shield. The bobbin, as one of their primary structural components, provides the necessary support for the coil assembly and core, thus playing an irreplaceable and important role. Lead wires are the positive and negative electrodes extending outward from the windings. Lead wires, especially those at the start of windings, can easily come into contact with the winding layers, potentially causing short circuits in the coils.

[0023] To solve the above problems, see Figure 1 and Figure 3 As shown, an embodiment of the present invention provides a winding device, which includes a winding body and a winding groove, wherein the winding body includes a winding shaft 10 and a first end plate 11 and a second end plate 12 respectively arranged at both ends of the winding shaft 10, the electromagnetic coil is wound on the winding shaft 10, and the side wall of the first end plate 11 is provided with a first plane 113; the lead groove 20 is provided on the first end plate 11, the lead groove 20 includes a lead segment 21 and a transition segment 22, the lead segment 21 is set at a predetermined angle to the first plane 113, the first end of the transition segment 22 is connected to the lead segment 21, and the second end of the transition segment 22 extends toward the winding shaft 10, and the lead of the electromagnetic coil is wound on the winding shaft 10 through the lead segment 21 and the transition segment 22. The winding device of the present invention provides a lead groove on the first end plate so that the lead of the electromagnetic coil can be hidden in the lead groove, preventing the lead from contacting the winding layer, greatly reducing the risk of coil short circuit, and providing a transition section 22 so that the lead can smoothly transition to the lead groove to prevent damage to the lead.

[0024] At the same time, the lead segments of the lead slots are arranged at a predetermined angle relative to the first plane to facilitate mold opening. The predetermined angle is between 45° and 135°. Since injection molding is best performed with horizontal and vertical drafting, to further facilitate mold opening and positioning, in a preferred embodiment, the predetermined angle is 90°.

[0025] Because the transition section 22 and the lead section 21 are oriented in different directions and are shorter than the lead section, in order to precisely machine the transition section, a machining groove 111 is provided on the first end plate 11 in this embodiment. The first end of the machining groove 111 is connected to the transition section 22, and the second end of the machining groove 111 extends away from the first plane 113, forming a starting opening 112 at the end of the first end plate 11. By providing the machining groove, the machining path can be determined more precisely, thereby making the position of the transition section more accurate. After machining is completed, the machining groove can also serve as a clearance slot for excess lead wire. In other embodiments, to facilitate machining, the transition section 22 can be formed by directly drilling a hole in the first end plate, with the first end of the hole connected to the lead section and the second end facing the winding shaft 10.

[0026] In order to facilitate machining and positioning, the length direction of the machining groove 111 in this embodiment is parallel to the length direction of the lead segment 21. When machining the transition segment, the machining groove can be machined parallel to the lead segment 21 to make the machining more accurate.

[0027] In order to enable the transition section to gradually guide the lead to the lead groove, the second end of the transition section 22 in this embodiment is provided with a guide end surface 23, which gradually extends toward the depth direction of the first end plate 11, thereby making the lead path smoother and preventing the lead from being damaged.

[0028] See also Figure 3 As shown, in another embodiment, in order to facilitate processing, a through hole 114 is provided at the second end of the transition section 22 in this embodiment. The through hole 114 passes through the first end plate 113 to make the processing positioning and grooving process more accurate.

[0029] Specifically, the winding device in this embodiment further includes a pin 30 , which is mounted on the first end plate 11 and protrudes from the first plane 113 , and the lead wire of the electromagnetic coil is wound around the pin 30 .

[0030] In order to prevent the lead wires entering the lead wire segment 21 from escaping from the lead wire segment 21, the winding device in this embodiment further includes a baffle 24. The baffle 24 is formed on the side of the first end plate 11 close to the second end plate 12. The baffle 24 partially blocks the lead wire segment 21. The baffle blocks the lead wires in the lead wire segment and prevents them from escaping, which facilitates the winding of the electromagnetic coil during the processing. It also prevents the lead wires from contacting the winding layer, greatly reducing the risk of coil short circuit.

[0031] The winding device in this embodiment also includes a pin 30, which is mounted on the first end plate 11 and protrudes from the first plane 113. The lead wire of the electromagnetic coil is wound around the pin 30, and the lead wire coming out of the lead groove needs to be wound around the pin. In order to prevent this part of the lead wire from being damaged, a guiding convex surface is provided on the inner wall of the lead segment 21 on the side close to the pin 30. The guiding convex surface is bent in the direction close to the pin 30. The transition of the lead wire is achieved through the guiding convex surface, so that the lead wire is smoothly guided to the pin.

[0032] In another embodiment, the winding device in this embodiment also includes a pin 30, which is mounted on the first end plate 11 and protrudes from the first plane 11. The lead wire of the electromagnetic coil is wound around the pin 30, and the lead wire coming out of the lead groove needs to be wound around the pin. In order to prevent this part of the lead wire from being damaged, a guide slope is provided on the inner wall of the lead segment 21 on the side close to the pin 30. The guide slope extends in the direction close to the pin 30. The transition of the lead wire is achieved through the guide slope, so that the lead wire is smoothly guided to the pin.

[0033] In order to further prevent the leads in the lead groove from falling out, a protrusion 25 is provided at one end of the baffle 24 close to the pin 30 in this embodiment. The protrusion 25 protrudes from the first plane 113. The protrusion 25 blocks the leads at the top of the lead groove, further preventing the leads from falling out.

[0034] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0035] The winding device of the present invention provides a lead groove on the first end plate, so that the lead of the electromagnetic coil can be hidden in the lead groove, preventing the lead from contacting the winding layer, greatly reducing the risk of coil short circuit, and providing a transition section so that the lead can smoothly transition to the lead groove to prevent damage to the lead.
