Description

Technical Field

[0001] This utility model belongs to the field of relay technology, and more specifically, it relates to a relay coil with a layered isolation structure. Background Technology

[0002] Currently, relays are widely used switching elements in electrical control systems, with their core component being a coil. When energized, the coil generates a magnetic field, driving the relay contacts to actuate and control the circuit's on / off state. However, existing relay coils suffer from the following problems in practical applications:

[0003] Heat dissipation problem: The coil generates heat during the energization process. If the heat is not dissipated in time, the coil temperature will rise, reducing its service life and possibly causing failure.

[0004] Electromagnetic interference problem: When the coil is working, it will generate an electromagnetic field, which will not only affect its own performance, but may also cause electromagnetic interference to surrounding electronic equipment, resulting in signal transmission errors or equipment malfunctions.

[0005] Insufficient structural strength: Traditional coils are mostly single-layer winding structures with low mechanical strength. They are easily deformed or damaged when subjected to external impact, affecting the reliability of the relay. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a relay coil with a layered isolation structure. By optimizing the coil's structural design, its heat dissipation performance, electromagnetic compatibility, and mechanical strength are improved, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a relay coil with a layered isolation structure, comprising a housing, a pin portion for connecting to an external circuit on one side of the housing, a base frame inside the housing, one side of the base frame connecting to the inside of the pin portion, an armature hinged to the top of the base frame, a return spring hanging at one end of the armature, the bottom of the return spring being snapped into a positioning plate on one side of the base frame, the other end of the armature located between switch contacts inside the pin portion, a magnetic attraction point for guidance below the armature, the magnetic attraction point being fixed to the top of the coil frame, and the coil frame being connected to... All armatures are connected to the pins via wires. The coil frame consists of a frame upper seat, a core support, and a frame base from top to bottom. The two ends of the core support are respectively fitted into the frame upper seat and the frame base. The frame base is mounted on the base frame. The core support has a through-hole in the middle and multiple longitudinal guide elongated holes on its circumference. The guide elongated holes are distributed circumferentially. The core support has a layered isolation structure, which is stably guided through the guide elongated holes. The layered isolation structure adopts a top-bottom layered design, with a first coil group, a second coil group, and a third coil group wound from bottom to top.

[0008] As an optional solution of this utility model, the top of the lower frame is provided with a lower heat dissipation channel for conducting heat away from the first coil group.

[0009] As an optional solution of this utility model, the bottom of the upper frame is provided with an upper heat dissipation channel. The upper heat dissipation channel and the lower heat dissipation channel have the same shape and area, and both adopt an inner and outer annular groove connection design.

[0010] As an optional solution of this utility model, the layered isolation structure includes a micro motor connected to an external circuit. The micro motor is fixed inside the base and assembled at the bottom of the iron core support. The drive end of the micro motor is connected to a micro adjusting screw through an adapter block. The top of the micro adjusting screw is mounted in the upper seat of the frame through a bearing. A pair of threaded iron blocks are threadedly engaged on the micro adjusting screw. The distance between the threaded iron blocks remains constant. An insulating isolation disc is provided on the threaded iron blocks. The insulating isolation disc is slidably engaged in the guide elongated hole.

[0011] As an optional solution of this utility model, the insulating isolation disk is provided with heat dissipation grooves, which divide it into multiple fan-shaped support surfaces of the same area.

[0012] As an optional solution of this utility model, a heat-absorbing layer is provided on the fan-shaped support surface. The heat-absorbing layer is made of graphene material and has a thickness of 0.2 mm.

[0013] This utility model provides a relay coil with a layered isolation structure, which has the following advantages:

[0014] By designing a through-core support, a micro motor and a micro adjusting screw can be installed, allowing for flexible adjustment of the insulating isolation disc. The insulating isolation disc moves synchronously, thereby increasing or decreasing the spacing of the first coil group. Increasing the spacing can dissipate heat and weaken the magnetic field, while decreasing the spacing can concentrate the magnetic field strength, improving the sensitivity of the top and achieving dynamic adjustment balance. This makes operation more flexible and safer. By designing heat dissipation grooves and heat absorption layers on the insulating isolation disc, combined heat dissipation and heat absorption can be achieved, enhancing the coil's heat dissipation and improving the stability of the internal structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a relay coil with a layered isolation structure, including a housing 1, a pin portion 101 for connecting to an external circuit is provided on one side of the housing 1, a base frame 2 is provided inside the housing 1, one side of the base frame 2 is connected to the inside of the pin portion 101, an armature 4 is hinged to the top of the base frame 2, a return spring 3 is hung on one end of the armature 4, the bottom of the return spring 3 is snapped into a positioning plate on one side of the base frame 2, the other end of the armature 4 is located between switch contacts 102 inside the pin portion 101 for controlling the switch, a magnetic attraction point 7 for guiding is provided below the armature 4, the magnetic attraction point 7 is fixed to the top of the coil frame, and the coil frame and the armature 4 are both connected to the pin portion 101 through wires 401.

[0024] The coil frame consists of a frame upper seat 6, an iron core support column 13, and a frame base 5 from top to bottom. The two ends of the iron core support column 13 are respectively fitted into the frame upper seat 6 and the frame base 5. The frame base 5 is mounted on the base frame 2. The iron core support column 13 has a through-hole in the middle and multiple longitudinal guide elongated holes 131 are provided on the circumference of the iron core support column 13. The guide elongated holes 131 are distributed in a circle. The iron core support column 13 has a layered isolation structure and is stably guided through the guide elongated holes 131.

[0025] The layered isolation structure adopts an upper and lower layered design, with the first coil group 8, the second coil group 9, and the third coil group 10 wound from bottom to top respectively. The lower frame is provided with a lower heat dissipation channel 501 at the top to conduct heat away from the first coil group 8. The upper frame is provided with an upper heat dissipation channel 601 at the bottom. The upper heat dissipation channel 601 and the lower heat dissipation channel 501 have the same shape and area, and both adopt an inner and outer annular groove connection design to stably dissipate heat from the inside and outside of the coil.

[0026] The layered isolation structure includes a micro motor 14 connected to an external circuit. The micro motor 14 is fixed inside the base and assembled at the bottom of the iron core support 13. The drive end of the micro motor 14 is connected to a micro adjusting screw 141 through an adapter block. The top of the micro adjusting screw 141 is mounted in the upper frame 6 through a bearing. A pair of threaded iron blocks 112 are threadedly engaged on the micro adjusting screw 141. The distance between the threaded iron blocks 112 remains constant. An insulating isolation plate 11 is provided on the threaded iron blocks 112. The insulating isolation plate 11 slides in the guide elongated hole 131.

[0027] The insulating isolation disk 11 is provided with heat dissipation grooves 111, which divide the disk into multiple fan-shaped support surfaces of the same area. A heat absorption layer 12 is provided on the fan-shaped support surface. The heat absorption layer 12 is made of graphene material with a thickness of 0.2mm. It can absorb heat while dissipating heat, further reducing the coil temperature. The insulating isolation disk 11 is adjusted up and down by the micro motor 14, thereby increasing or decreasing the spacing of the first coil group 8 to achieve a stepped distribution. The gradually increasing or decreasing spacing can generate a non-uniform magnetic field distribution.

[0028] For example, gradually decreasing the spacing can enhance the concentration of the magnetic field, making the magnetic field stronger in certain areas, thereby improving the sensitivity or response speed of the relay. By adjusting the spacing, the heat distribution inside the coil can be optimized to prevent local overheating.

[0029] The specific usage and function of this embodiment are as follows: Initially, the first coil group 8, the second coil group 9, and the third coil group 10 are all equidistantly distributed and independently insulated. When the first coil group 8 at the bottom overheats or the magnetic field strength is too high, the micro motor 14 is activated to drive the insulating isolation disk 11 to move synchronously, thereby increasing the spacing of the first coil group 8, thus dissipating heat and weakening the magnetic field. At this time, the spacing of the third coil group 10 is the smallest, the intensity is concentrated, and the sensitivity of the top is improved. Conversely, when the intensity of the third coil group 10 at the top is too high or overheats, the operation is repeated to achieve dynamic adjustment and balance, making the operation more flexible and safer.
