Description

Technical Field

[0001] The utility model relates to the technical field of transformer coils, and specifically relates to a transformer coil structure. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. It mainly consists of an iron core (or magnetic core) and a coil. Its main functions include: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers are commonly used in the electronics and electromechanical industries in the current market.

[0003] The specifications of the existing transformer coil structures are generally fixed. In order to match the current, wires of different lengths need to be wound. In order to ensure the consistent thickness of the wire winding, a wire winding coil that matches needs to be manufactured for adaptation. Manufacturing a wire winding coil that matches requires additional custom processes and production costs. Every time a transformer of a different specification is needed, the coil needs to be redesigned and manufactured, increasing the production cost and time cost. If the demand for transformer coils of certain specifications is small, but they are manufactured to meet the production demand, it will cause waste of resources. To solve the above problems, a transformer coil structure is proposed. Summary of the Utility Model

[0012] Compared with the prior art, the advantages of the present utility model are as follows:

[0013] 1. The present utility model drives the rotating column to rotate by setting a rotating cap. Through the cooperation of the external thread and the threaded disk, the first disk body is lifted and lowered, thereby adjusting the distance between the first disk body and the second disk body, and further adjusting the specification of the wire winding coil.

[0022] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0023] Referring to Figures 1-5 As shown, a transformer coil structure includes a base 1. A connecting column 4 is fixedly installed at the upper end of the base 1. As the core support component of the entire coil structure, through a plurality of groups of wire winding assemblies 7 arranged on its outer side, a stable foundation is provided for the winding of the coil. A plurality of groups of wire winding assemblies 7 are arranged on the outer side of the connecting column 4. An installation chamber 8 is opened inside the connecting column 4. A rotating column 9 is rotatably connected inside the installation chamber 8. A plurality of external threads 10 are provided on the surface of the rotating column 9. A plurality of threaded disks 11 are threadedly connected to the outside of the rotating column 9 through the external threads 10. The top of the rotating column 9 is fixedly connected to the outside of the connecting column 4 by a rotating cap 12. A moving groove 6 is penetrated and opened on the rear surface of the connecting column 4. The moving groove 6 can also limit the threaded disk 11 to prevent the threaded disk 11 from rotating selflessly, resulting in the inability to lift the first disk body 701. The threaded disk 11 passes through the moving groove 6 and is connected to the wire winding assembly 7.

[0024] It should be noted that the wire winding assembly 7 includes a first disk body 701 and a second disk body 704. The first disk body 701 is slidably connected to the outside of the connecting column 4, and the threaded disk 11 is fixedly connected to the inside of the first disk body 701. The second disk body 704 is fixedly connected to the outer surface of the connecting column 4. The first disk body 701 and the second disk body 704 cooperate to form the winding area of the coil. The sliding connection design of the first disk body 701, combined with the adjustment of the threaded disk 11, can flexibly adjust the tightness and shape of the coil.

[0025] Specifically, a first guiding ramp 702 is fixedly connected to the outer periphery of the first disk body 701, and a second guiding ramp 705 is fixedly connected to the outer periphery of the second disk body 704.

[0026] Specifically, a first wire outlet groove 703 is formed through the front side of the upper surface of the first disk body 701, and a second wire outlet groove 706 is fixedly connected to the position corresponding to the first wire outlet groove 703 on the upper surface of the second disk body 704. The first wire outlet groove 703 and the second wire outlet groove 706 provide a clear path for the lead wires of the wire, facilitating installation and wiring. At the same time, through the corresponding setting of the second wire outlet groove 706 on the second disk body 704 and the first wire outlet groove 703, the neatness and beauty of the lead wires are ensured.

[0027] Specifically, a T-shaped groove 5 is formed inside the upper end of the connecting column 4, the bottom of the rotating cap 12 is fixedly connected to the T-shaped block 13, and the T-shaped block 13 is rotatably connected to the inside of the T-shaped groove 5. The rotating cap 12 serves as an operating component for adjustment. Through the connection with the T-shaped block 13 and the rotational connection of the T-shaped block 13 inside the T-shaped groove 5, convenient adjustment and fixation of the entire coil structure are achieved.

[0028] Specifically, fixing seats 2 are fixedly connected to both the left and right sides of the base 1, and a plurality of pins 3 are fixedly connected to the fixing seats 2. The pins 3 provide an interface for the connection between the coil and the external circuit, facilitating the access and use of the coil.

[0029] Preferably, the first guiding ramp 702 and the second guiding ramp 705 are arranged obliquely relative to each other, and the included angle formed by the first guiding ramp 702 and the second guiding ramp 705 is 15 degrees to 35 degrees. Such a design is conducive to the smooth entry and tight winding of the wire, reducing the gap and loss between the first disk body 701 and the second disk body 704.

[0030] Working principle: When adjusting the specifications of the coil, only need to turn the rotating cap 12 to drive the rotating column 9 to rotate. Through the cooperation of the external thread 10 and the threaded disk 11, the first disk body 701 axially moves along the moving groove 6, thereby adjusting the distance between the first disk body 701 and the second disk body 704. On the premise of ensuring the same winding thickness, this is used to adapt to the winding of wires of different lengths.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
