Coiling base applicable to transformer structure

Abstract

The invention relates to a coiling base which is applicable to a transformer structure. The coiling base at least comprises a body and a plurality of connecting seats, wherein two opposite sides of the body are respectively provided with a side wall, and a coiling region is formed between the side walls and is used for winding a coiling structure; the connecting seats are respectively arranged ontwo opposite sides of the body and are connected with the side walls, and the bottoms of the connecting seats are provided with a plurality of wire sorting slots; and each side wall is provided with a concave slot which is communicated with the wire sorting slots, so that the start winding portions of the coiling structure are accommodated in the wire sorting slots and the concave slots to prevent the start winding portions from rubbing with the coiling structure subsequently wound in the coiling region. Through the coiling base, the friction between the start winding portions and the coilingstructure subsequently wound in the coiling region is prevented, and the fracture of the wire outgoing end of the coiling structure can be prevented. In addition, the efficacy of preventing tin solders welded on two adjacent connecting portions from being connected can be achieved.

Description

technical field [0001] The invention relates to a winding base, in particular to a winding base suitable for a transformer structure. Background technique [0002] Transformer is a magnetic component often used in various electrical equipment. It uses the principle of electric energy and magnetic energy conversion induction to adjust different voltages to make it reach the applicable range of electrical equipment. [0003] see Figure 1A , which is a structural schematic diagram of a known transformer. As shown in the figure, the transformer 1 includes a winding base 11 (bobbin), a cover 12 (cover) and a magnetic core assembly 13 (magnetic core assembly), wherein a primary winding coil 111 (primary winding coil) and a secondary winding coil 112 (secondary winding coil) is wound on the winding base 11, and its outlet ends 113, 114 are then wound and welded on the connecting portion 117, while the other end of the plug-in portion 115 is plugged into a system circuit board (no...

Problems solved by technology

[0008] The main purpose of the present invention is to provide a winding base suitable for a transformer structure, so as to solve the problem that when the known transformer structure is plugged on the system circuit board, the L-shaped lead pins will be loosened due to the assembly process, and the welding When the outlet ends of the primary winding and the secondary winding on the connection part of the lead pin are broken, and the outlet ends of the primary winding and the secondary winding are wound and welded on the connection part, the connection between the two adjacent connection parts There will be a short circuit caused by solder connection between

[0009] Another object of the present invention is to provide a winding base suitable for a transformer structure, so as to solve the problem that the design of the winding base of the known transformer structure will cause the initial winding of the primary winding and the secondary winding to be repeated. Subsequent winding friction will cause the insulating varnish on the surface of the initial winding to be worn away, resulting in poor insulation and prone to instant sparks
