Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water pump coil winding installation structure. Background Art

[0002] In the structure of a water pump, the coil winding is one of the essential and important structures. The coil winding on the existing water pump is usually wound around the outside of the magnetic core during installation. The lead-out terminal formed by the coil winding after winding is usually directly welded and fixed on the printed circuit board in the prior art. This structure may cause welding failure due to the flexibility of the coil winding itself, and the welding is difficult. Therefore, we have re-proposed an installation structure for the coil winding used in the water pump. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a water pump coil winding installation structure, which solves the problems raised by the above-mentioned background technology.

[0005] Support frame;

[0006] A magnetic core body, wherein the magnetic core body is sleeved on the outside of the supporting frame, the bottom of the magnetic core body is connected to an extension part, and the bottom end of the extension part is connected to a pin needle;

[0007] A coil winding, wherein the coil winding is wound around the outside of the magnetic core, and the lead end of the magnetic core is wound around the outside of the pin needle;

[0008] A printed circuit board is located below the magnetic core body, and the bottom end of the pin needle is fixed on the surface of the printed circuit board.

[0009] Furthermore, the magnetic core body is a "U"-shaped structure.

[0010] Furthermore, a reserved hole is formed through the interior of the magnetic core body, and two ends of the support frame pass through the interior of the reserved hole.

[0011] Furthermore, a circle around the surface of the magnetic core body is arranged as a winding portion, and the coil winding is arranged outside the winding portion.

[0012] Furthermore, the winding portion is a structure with protrusions on both sides and a depression in the middle.

[0013] Furthermore, the extension portion and the magnetic core body are made of the same material, and the pin needle is made of a conductive material.

[0014] Furthermore, a U-shaped groove is reserved on the printed circuit board, and the pin is fixed in the U-shaped groove.

[0015] Compared with the above-mentioned background technology, the water pump coil winding installation structure provided in the present application includes a supporting frame, two groups of magnetic core bodies, coil windings and a printed circuit board. When designing the magnetic core body, an additional group of pin needle structures are added. After the coil winding is wound around the outside of the magnetic core body, its lead end is first wound around the outside of the pin needle, and then the pin needle is welded and fixed to the corresponding area of ​​the printed circuit board.

[0016] The utility model provides a water pump coil winding installation structure. Compared with the prior art, it has the following beneficial effects:

[0017] The water pump coil winding installation structure improves the magnetic core structure of the carrier wound by the existing water pump coil winding. When manufacturing the magnetic core, an additional extension part is integrally formed on the magnetic core, and a pin needle is connected to the extension part. After the coil winding is wound on the surface of the magnetic core, the lead end of the coil winding needs to be wound on the outside of the pin needle, and then the pin needle is welded to the circuit board, instead of directly welding the lead end to the circuit board as in the prior art. The advantage of this structure is that there is no need to consider the problem of welding failure caused by the flexibility of the coil winding itself. Not only can the stability of the structure be further improved, but the manufacturing difficulty is also greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS
