[0012] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0013] The utility model provides an insulating frame for winding the enameled wire, which is formed by splicing an insulating rear shell and an insulating front cover by means of a card block and a card slot, so that the heat dissipation ventilation slots and a heat dissipation cavity for heat dissipation can be conveniently processed, and the heat dissipation ventilation slots and the heat dissipation cavity play a role in heat dissipation for the inductor during operation, that is, after the inductor is installed on the circuit board, since electronic components are generally equipped with a heat dissipation fan inside, the cold air flow generated by the heat dissipation fan will be discharged to the inside of a plurality of heat dissipation cavities through the auxiliary positioning parts after passing through the heat dissipation ventilation slots, and then transported to the surface of the enameled wire through the heat dissipation cavity.

DETAILED DESCRIPTION

[0025] The utility model is now described in further detail with reference to the accompanying drawings.

[0026] See also Figures 1 to 6 The utility model provides a technical solution: a combined integrated inductor, comprising an insulating frame and an enameled wire 2, wherein a pin 1 plugged into a circuit board is provided at the bottom of the insulating frame, and the enameled wire 2 is wound around the outside of the middle end of the insulating frame, and the two ends of the enameled wire 2 are respectively connected to two pins 1;

[0027] The insulating skeleton includes an insulating rear shell 3 and an insulating front cover 4, and heat dissipation ventilation grooves 5 are provided in the middle of the insulating front cover 4 and the insulating rear shell 3, and multiple heat dissipation cavities 6 connected to the inside of the heat dissipation ventilation grooves 5 are provided at equal intervals on both sides of the two heat dissipation ventilation grooves 5. Considering that a large amount of heat is often generated during the operation of the inductor, the common combined inductor lacks its own heat dissipation and heat removal ability. Heat accumulation during long-term operation is likely to cause changes in electrical characteristics, affecting the normal operation of the circuit. The insulating skeleton for winding the enameled wire 2 of the utility model is spliced ​​by the insulating rear shell 3 and the insulating front cover 4 through the card block 7 and the card slot 8, which is convenient for processing the heat dissipation ventilation grooves 5 and the heat dissipation cavity 6 for heat dissipation, and the heat dissipation ventilation grooves 5 and the heat dissipation cavity 6 play a role in heat dissipation for the inductor when it is working, that is, after the inductor is installed on the circuit board, since the electronic components are generally equipped with a heat dissipation fan inside, the cold air flow generated by the heat dissipation fan will pass through the auxiliary positioning piece through the heat dissipation ventilation grooves 5 and then be discharged to the inside of the multiple heat dissipation cavities 6, and then be transported to the surface of the enameled wire 2 by the heat dissipation cavity 6.

[0028] Among them, the insulating front cover 4 and the insulating rear shell 3 are fixed by multiple clamping blocks 7 and multiple clamping slots 8. The multiple clamping blocks 7 are respectively fixed at the four corners of the back of the insulating front cover 4, and the multiple clamping slots 8 are opened at the four corners of the front end of the insulating rear shell 3. The installation of the insulating front cover 4 and the insulating rear shell 3 is convenient by setting the clamping blocks 7 and the clamping slots 8. After the insulating rear shell 3 and the insulating front cover 4 are clamped, since the enameled wire 2 needs to be wrapped around the outside, the clamping installation method can also have better stability. And since it can be assembled and disassembled, when the factory processes the two components, the heat dissipation cavity 6 and the heat dissipation ventilation groove 5 can be quickly opened on their surfaces.

[0029] Among them, half grooves 9 for embedding the two ends of the enameled wire 2 are provided on both sides of the lower ends of the insulating front cover 4 and the insulating rear shell 3, and the inner sides of the two half grooves 9 are fixed with interference protrusions 10 for interfering with the outer walls of the enameled wire 2 embedded in the half grooves 9. The half grooves 9 provided on both sides of the lower ends of the insulating front cover 4 and the insulating rear shell 3 facilitate the insertion of the enameled wire 2. After the enameled wire 2 is inserted, the two interference protrusions 10 can be used to interfere with the surface of the enameled wire 2 to prevent the enameled wire 2 from slipping, thereby limiting the two ends of the enameled wire 2.

[0030] Among them, the bottoms of the insulating front cover 4 and the insulating rear shell 3 are symmetrically fixed with abutment strips 13 fixed with the positioning holes 12 of the auxiliary positioning tube 11, and the two sides of the bottom of the auxiliary positioning tube 11 are integrally formed with protruding outer edges 15 for resisting the plug-in holes 14 of the circuit board, and the front and rear sides of the auxiliary positioning tube 11 are provided with pressing grooves 16 for users to press the left and right sides of the auxiliary positioning tube 11. Considering that most of the existing inductors have been installed with the circuit board in a direct plug-in manner for the convenience of installation, but this method will make the pin 1 as a connection point, which is easy to break after being vibrated or touched, the utility model can use the auxiliary positioning tube 11 to connect with the plug-in hole 14 of the circuit board, so as to share the force that the pin 1 bears when it is touched and vibrated, thereby improving The stability of the inductor during use is improved. During installation, first complete the clamping of the insulating front cover 4 and the insulating rear shell 3, then take out the auxiliary positioning tube 11, and connect the upper end positioning hole 12 of the auxiliary positioning tube 11 with the contact strip 13, that is, the contact strip 13 is compressed and retracted. When it is inserted into the positioning hole 12 and is no longer subjected to force, it is reset, and then the side of the contact strip 13 is buckled on the edge of the port of the positioning port to complete the fixation, and then the device is connected to the circuit board through the auxiliary positioning tube 11, that is, the two sides of the auxiliary positioning tube 11 are pressed, and then the two sides of the auxiliary positioning tube 11 are compressed and enter the plug hole 14, and then the device is continuously pushed in. When the auxiliary positioning tube 11 passes through the plug hole 14, the auxiliary positioning tube 11 is reset, and the protruding outer edges 15 on both sides thereof contact with the port of the plug hole 14 to limit the position.

[0031] Among them, embedding grooves 17 for winding the enameled wire 2 are equally spaced in the middle of the outer side walls of the insulating front cover 4 and the insulating rear shell 3, and the embedding grooves 17 and the heat dissipation channels 6 are staggeredly distributed on the outer sides of the insulating front cover 4 and the insulating rear shell 3. By providing the embedding grooves 17, it is convenient for the user to wind the enameled wire 2 according to the embedding grooves 17, so as to ensure that each ventilation can just deliver the cold air to the surface of the enameled wire 2 for heat dissipation.

[0032] The present utility model is not limited to the above embodiments. Any person should know that the structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all fall within the protection scope of the present utility model. The technologies, shapes, and structures not described in detail in the present utility model are all well-known technologies.
