[0002] The circulating pump coil is a key component in the circulating pump. Its main function is to convert electric current into magnetic field. The conversion is based on the principle of electromagnetic induction. When power is turned on, the magnetic field generated by the current change in the coil acts on the water, allowing the water to form a rotating force in the pump.

[0003] For example, China's patent announcement number CN205823658U discloses a magnetic levitation variable frequency intelligent circulation pump, which includes a circulation pump body, which includes a pump body, a cavity is arranged in the pump body, a control board is arranged on the bottom surface of the cavity, a shielding sleeve is arranged on the control board, a bearing is arranged on the bottom surface of the shielding sleeve, a stainless steel gasket is arranged on the bearing, a central axis is arranged in the bearing, a permanent magnet rotor and an impeller are arranged on the central axis, a coil is arranged at the lower part of the shielding sleeve, and the permanent magnet rotor is inserted into the coil.

[0004] The above-mentioned magnetic levitation variable frequency intelligent circulation pump has an existing coil connected to a motor, and the motor is connected to a permanent magnet rotor and an impeller and drives them to rotate. Poor grounding can easily cause electrical failures. To avoid leakage or static electricity accumulation, a grounding contact piece needs to be installed, which is troublesome to use and needs to be improved. Summary of the invention

[0005] In order to improve the problem of inconvenient installation and use of the grounding contact, the present technical solution provides a plug-in coil structure.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A plug-in coil structure includes an iron core, the iron core is provided with a mounting seat, the mounting seat is plugged with a grounding plug, the grounding plug includes a grounding seat arranged on the mounting seat and a conductive plug arranged on the grounding seat, the conductive plug is connected to an electric wire, a positioning groove is opened on the outer wall of the iron core, the conductive plug is embedded in the grounding seat, and the electric wire extends to the positioning groove for contacting the iron core.

[0008] Through the above technical scheme, when the plug-in coil structure is used normally, the mounting base is installed on the iron core, the grounding base in the grounding plug is plugged into the mounting base, and the conductive plug is inserted into the grounding base, so that one end of the conductive plug protrudes from the end face of the grounding base away from the mounting base and extends for grounding, ensuring the grounding connection. Based on the conductive plug connected with an electric wire, the electric wire is adapted to the positioning groove, and the electric wire is buried in the positioning groove to reduce the damage of the electric wire caused by external force. After extending in the positioning groove, the electric wire contacts the iron core, and the iron core transmits electricity through the electric wire to realize the grounding use of the grounding plug, making the grounding use simple, fast and convenient.

[0009] Preferably, the mounting seat is provided with a wire arrangement groove, the wire arrangement groove is correspondingly connected to the positioning groove, and the wire arrangement groove is used for embedding the power supply wire.

[0010] Through the above technical scheme, the electric conductor is adapted to the cable trough of the mounting seat, and the electric conductor is first embedded in the cable trough. The cable trough provides a designated path and is laid along the length direction of the cable trough. The cable trough prevents the electric conductor from being exposed on the mounting seat to further reduce external interference. Based on the connection between the cable trough and the positioning groove, the electric conductor enters the positioning groove. The cable trough cooperates with the positioning groove to make the position of the electric conductor relatively fixed, thereby optimizing the guiding effect on the electric conductor, thereby improving the orderliness and stability of the use of the electric conductor.

[0011] Preferably, the mounting seat is provided with a fixing block, and the fixing block is mounted above the opening of the cable tray to limit the electrical wires from escaping.

[0012] Through the above technical solution, the fixing block is fixed to the mounting seat in an integral manner. When the electric wire is laid in the cable trough, the fixing block crosses an opening of the cable trough, thereby limiting the electric wire from accidentally detaching from the cable trough due to vibration, friction or other external factors, thereby further improving the installation stability.

[0013] Preferably, the mounting seat has a plurality of positioning blocks, and a mounting space is formed by cooperation between the plurality of positioning blocks, and the mounting space is used for inserting the grounding seat to limit rotation.

[0014] Through the above technical solution, multiple positioning blocks protrude from the upper end surface of the mounting base, and the shape of the mounting space formed by the multiple positioning blocks matches the lower end of the grounding base, so that the lower end of the grounding base is correspondingly embedded in the mounting space, and multiple matching blocks are arranged around the grounding base to interfere with each other to limit the rotation of the grounding base, thereby reducing shaking or rotation of the grounding base during installation and use.

[0015] Preferably, four positioning blocks are provided, and the four positioning blocks are distributed corresponding to the four corners of the grounding seat one by one.

[0016] Through the above technical solution, the lower end of the grounding socket is rectangular, and the four positioning blocks correspond one by one to the four corners of the rectangle, so that when the grounding socket is inserted into the installation space, it will receive balanced support from four directions, increasing the contact surface and limiting the space range, making it easier to calibrate the grounding socket and embed it into the installation space, thereby improving installation accuracy and stability.

[0017] Preferably, a fixing structure is provided between the mounting seat and the grounding seat, the fixing structure includes an embedded portion and a locking protrusion, the embedded portion and the locking protrusion are respectively arranged on the mounting seat and the grounding seat in a one-to-one correspondence, the embedded portion includes an elastic connecting portion and a limiting portion arranged on the elastic connecting portion, when the limiting portion is engaged with the locking protrusion, the grounding seat is fixedly installed on the mounting seat.

[0018] Through the above technical solution, the embedding part is arranged on one of the components of the mounting seat or the grounding seat, and the snap-in protrusion is arranged on the other component. The mounting seat and the grounding seat are fixed by a fixing structure, and the limiting part is pushed to contact the corresponding snap-in protrusion. The elastic deformation of the elastic connecting part enables the limiting part to be embedded with the snap-in protrusion through the snap-in protrusion, thereby further improving the installation stability of the grounding seat.

[0019] Preferably, the limiting portion has a guide surface, the snap-in protrusion has a guide slope, the guide surface is adapted to the inclination direction of the guide slope, and the guide slope and the guide surface are used to cooperate with the guide limiting portion and the snap-in protrusion to fit together.

[0020] Through the above technical solution, when the guide surface is opposite to the guide inclined surface, based on the consistency of the inclination directions of the guide surface and the guide inclined surface, the guide inclined surface will first fit in contact with the guide surface, so that the guide limit part can move smoothly along the direction of the guide surface until it is fully engaged with the snap-in protrusion, making the engagement speed faster and the installation more stable.

[0021] Preferably, a plurality of clearance holes are formed on the side wall of the grounding seat.

[0022] Through the above technical solution, the yield hole of the grounding socket strengthens the structure of the grounding socket, plays the role of a reinforcing rib for dispersing stress, increases the durability of the grounding socket, and thus improves the stability of the grounding plug.

[0023] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0025] 2. This technical solution provides a fixing structure between the mounting seat and the grounding seat. The fixing structure includes a snap-fitting portion and a snap-fitting protrusion.
