Description

Technical Field

[0001] This disclosure relates to the field of electromagnetic technology, and more particularly to a coil lead-out device. Background Technology

[0002] The coil body of an electromagnetic coil needs to be soldered to an external mechanism, and electromagnetic coils are generally designed as a separate adapter component. Since electromagnetic coils are typically wound with enameled wire, and the enamel coating on enameled wire is relatively thin, with some products using very fine wire diameters ranging from 0.07mm to 0.23mm, directly soldering the enameled wire to the external mechanism can easily cause the wire to break, resulting in poor circuit continuity.

[0003] In existing technologies, wires are typically soldered to enameled wires, and then the wires are led out and soldered to external mechanisms. Because the wires are flexible components, the soldering process cannot be completed quickly and requires various auxiliary positioning methods, resulting in long soldering times and low assembly efficiency of the electromagnetic coil.

[0004] To solve the above problems, a coil lead-out device was designed. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a coil lead-out device to improve the production efficiency and assembly efficiency of electromagnetic coils.

[0017] The lead wire at the starting end of the enameled wire passes through the lead groove and connects to one of the adapter pins.

[0018] In one exemplary embodiment of this disclosure, the two adapter pins are disposed on the two limiting plates.

[0019] In one exemplary embodiment of this disclosure, one of the two limiting plates is provided with a lead wire groove, which is located on one side of the adapter pin;

[0020] The lead wire at the starting end of the enameled wire passes through the lead groove and connects to the adapter pin.

[0021] In one exemplary embodiment of this disclosure, the other end of the adapter pin extends into the limiting plate and forms a limiting portion.

[0022] In one exemplary embodiment of this disclosure, the adapter pin is integrally formed onto the limiting plate by injection molding.

[0032] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0035] This disclosure provides a coil lead-out device, see [link to previous section] Figure 1It includes: a skeleton 1; an enameled wire 2 wound around the skeleton 1, with lead wires formed at both ends of the enameled wire 2; and two adapter pins 3 respectively disposed on the skeleton 1, the two adapter pins 3 located on the same side of the skeleton 1, with a plug-in part formed at the end of the adapter pin 3 away from the skeleton 1, the plug-in part being used for plugging and unplugging connection with an external mechanism; wherein, the two lead wires are respectively connected to the two adapter pins 3.

[0036] In this embodiment, the coil lead-out device consists of a frame 1, an enameled wire 2, and an adapter pin 3. The enameled wire 2 is wound around the frame 1. There are two adapter pins 3, which are installed on the frame 1. Leads are formed at both ends of the enameled wire 2. The lead at the starting end of the enameled wire 2 is connected to one adapter pin 3, and the lead at the ending end of the enameled wire 2 is connected to one adapter pin 3. A plug-in part is formed at the end of the adapter pin 3 away from the frame 1. The two plug-in parts face the same side of the frame 1 and are plugged into and connected to an external mechanism through the two plug-in parts to complete the production and assembly of the electromagnetic coil.

[0037] Compared to existing methods that use wires to connect enameled wires to external mechanisms, this coil lead-out device has a simple structure, facilitates the assembly and disassembly of the electromagnetic coil, ensures reliable contact, and improves the production and assembly efficiency of the electromagnetic coil.

[0038] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 2 The frame 1 includes a connecting post 101; limit plates 102 are respectively provided at both ends of the connecting post 101, the enameled wire 2 is wound around the connecting post 101, and the adapter pin 3 is disposed on the limit plate 102. In this way, the enameled wire 2 can be easily wound around the frame 1, the edge of the enameled wire 2 can be easily limited to prevent the enameled wire 2 from falling off the connecting post 101, and the connection between the enameled wire 2 and the adapter pin 3 can be easily made.

[0039] Optionally, the structures of the two limiting plates 102 may be the same or different.

[0040] In one example, the two limiting plates 102 have different structures.

[0041] In one embodiment of this disclosure, one of the two limiting plates 102 has a rectangular cross-section, and the other of the two limiting plates 102 has a circular cross-section.

[0042] Understandably, the enameled wire 2 is wound around the connecting post 101, and the adapter pin 3 is installed on the limiting plate 102, so that the enameled wire 2 and the adapter pin 3 form an electrical gap, avoiding interference between the enameled wire 2 and the adapter pin 3, and improving the safety of the electromagnetic coil.

[0043] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 2The adapter pin 3 is perpendicular to the axis of the connecting post 101. This allows for easy insertion and removal of the adapter pin 3 from external mechanisms, improving the assembly efficiency of the electromagnetic coil.

[0044] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 and Figure 2 Two adapter pins 3 are mounted on the same limiting plate 102. A lead-in groove 4 is provided on the limiting plate 102, located between the two adapter pins 3. The lead-out wire at the starting end of the enameled wire 2 passes through the lead-in groove 4 and connects to one of the adapter pins 3. This allows for convenient connection of the starting end of the enameled wire 2 to one adapter pin 3 and convenient connection of the ending end of the enameled wire 2 to the other adapter pin 3, enabling sequential winding of the enameled wire 2 and preventing winding tangles.

[0045] In one example, both adapter pins 3 are mounted on the rectangular limiting plate 102.

[0046] In another embodiment of this disclosure, two adapter pins 3 are disposed on two limiting plates 102; one of the two limiting plates 102 has a lead wire groove 4, which is located on one side of the adapter pin 3; the lead wire at the starting end of the enameled wire 2 passes through the lead wire groove 4 and connects to the adapter pin 3. In this way, it is possible to conveniently connect the starting end of the enameled wire 2 to one adapter pin 3 and the ending end of the enameled wire 2 to the other adapter pin 3, so as to realize the sequential winding of the enameled wire 2 and avoid the winding of the enameled wire 2 becoming tangled.

[0047] It is understandable that when the two adapter pins 3 are located on the same limiting plate 102, the lead-out device and the external mechanism adopt a single-ended plug-in connection; when the two adapter pins 3 are located on two limiting plates 102, the lead-out device and the external mechanism adopt a double-ended plug-in connection.

[0048] In one embodiment of this disclosure, the lead groove 4 has a broken cross-section, with one end of the lead groove 4 opening towards the connecting post 101 and the other end opening towards one of the adapter pins 3. This allows for convenient connection of the lead wire through the lead groove 4 to the adapter pin 3.

[0049] Optionally, the opening of the lead groove 4 facing the connecting post 101 is tangent to the outer wall of the connecting post 101.

[0050] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 3 The other end of the adapter pin 3 extends into the limiting plate 102 and forms a limiting part 5. In this way, the adapter pin 3 can be prevented from disengaging from the limiting plate 102, and it is convenient to connect to external mechanisms by inserting and removing the adapter pin 3.

[0051] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 3The adapter pin 3 is integrally molded onto the limiting plate 102 using an injection molding process. This allows the adapter pin 3 and the frame 1 to form an integrated structure, thereby improving the stability of the electrical connection of the device.

[0052] In one embodiment of this disclosure, the lead wire is soldered to the adapter pin 3. This ensures a secure connection between the enameled wire 2 and the adapter pin 3, preventing the enameled wire 2 from detaching from the adapter pin 3 and facilitating the connection of the coil to an external mechanism.

[0053] Optionally, the lead wire is wound around the adapter pin 3 and then soldered to the adapter pin 3.

[0054] Optionally, the soldering area between the lead wire and the adapter pin 3 is coated with insulating adhesive.

[0055] In one embodiment of this disclosure, see Figures 1 to 3 The working process of this coil lead-out device is briefly described as follows:

[0056] In use, the enameled wire 2 is first spirally wound onto the connecting post 101 to form a coil. The wound coil is then limited by two limiting plates 102. The starting end of the enameled wire 2 is passed through the lead groove 4 and soldered to one of the adapter pins 3. The ending end of the enameled wire 2 is soldered to the other adapter pin 3 to complete the assembly of the lead-out device. Then, the assembled lead-out device is plugged into and connected to an external mechanism through two adapter pins 3 with plug-in parts to complete the assembly of the lead-out device.

[0057] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
