Technical Field
[0001] The utility model relates to the technical field of electrical components, in particular to a common mode inductor enameled wire winding jig. Background Art
[0002] Common-mode inductors, as key electronic components, are widely used and play an important role in the fields of new energy technologies and computers. They not only suppress common-mode noise through the interaction of magnetic fields, but also allow differential-mode signals to pass without interference, helping to improve system efficiency and stability.
[0003] In existing technology, common-mode inductors primarily consist of a common-mode inductor core, two coils mounted on the core, a partition, and a base. The two coils have the same number of turns and phase, a partition is placed in the middle of the core, and a base is located at the bottom of the common-mode inductor. The base has pin holes, which connect the four pins on the common-mode inductor to the pin holes, forming a plug-in structure. However, the enameled wire of the common-mode inductor cannot be bent as required during the folding process, and the paint may peel due to friction during production, reducing the safety and reliability of the common-mode inductor. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to provide a common mode inductor enameled wire winding jig to solve the above problems.
[0005] The technical solution of the utility model for solving the above technical problems is: a common mode inductor enameled wire winding jig, the jig including a limit groove, a clamping groove is respectively opened on the front and rear sides of the limit groove, a through hole is respectively opened on the left and right sides of the limit groove, a stop block is fixedly connected to the outside of the limit groove, the angle between the stop block and the limit groove constitutes a first groove, and a fixed block is fixedly connected to the front side of the stop block, and the angle between the fixed block and the limit groove constitutes a second groove.
[0006] As a preferred technical solution of the present invention, the fixture is integrally formed and has a symmetrical structure.
[0007] As a preferred technical solution of the present invention, there are two card slots on a single side, and they are arranged side by side.
[0008] As a preferred technical solution of the present invention, the diameter of the through hole is 1-1.5 mm.
[0009] As a preferred technical solution of the present invention, the front end of the stopper is provided with an inclined surface structure.
[0010] As a preferred technical solution of the present invention, the length, width and height of the fixture are 40-45 mm, 45-55 mm and 17-20 mm respectively.
[0011] Since the utility model adopts such a structure, the common-mode inductor enameled wire can be folded into the shape required for production more conveniently and effortlessly during the folding process, and the stop block is set with a rounded corner to reduce the friction and paint loss of the enameled wire during the folding process, thereby improving the safety and reliability of the common-mode inductor, greatly improving work efficiency, and improving the performance of electronic components to meet production needs.
