Problems solved by technology

[0003] In the technical field of existing transformer bobbins for electronic products, the bobbins have a single purpose. After the products are eliminated, the supporting coil bobbins and molds are also discarded; when the performance requirements of the same electrical appliances are different in the layout of the electronic circuit board, the transformer needs to be redesigned, resulting in a lot of waste. Time and labor costs; in realizing fully automated production of different skeletons, it is necessary to repeatedly debug and set the program of the winding machine. Debugging and setting include: winding operation and soldering, magnetic core assembly, magnetic core tape, Comprehensive electrical performance testing, withstand voltage testing, dipping in insulating varnish and other processes; it is inconvenient for production and wastes time and labor costs

Embodiment approach 1

[0028] The first implementation mode is: a combined high-frequency transformer coil bobbin, which is suitable for a fully automatic winding bobbin. Primary and secondary coils can be wound on the winding shaft in the winding area 3 of the bobbin body 2. There are five terminals on one side of the bobbin Pin 5 has five wire passage slots 8, and each side of each terminal pin 5 corresponds to a wire hanging bump 7 for hanging wires, so the primary winding incoming and outgoing wires can be allocated to separate wire passage slots 8, which can avoid winding gaps between windings. A short-circuit accident occurs; there are five terminal feet 5 on the secondary side of the skeleton, and four wire slots on the primary side; insert the magnetic core 41 into the core hole of the skeleton, and assemble the magnetic core 41 and the skeleton body 2 with the coil and the base 1 Together, there are four fasteners 11 on the base, and a quick connection clip 10 is provided on the base 1 for e...

Embodiment approach 2

[0033] The scheme of the second embodiment is as follows: the base 1 adopts a split structure design and is formed by splicing two halves. This makes assembly easier.

[0034] The horizontal and vertical skeletons of the combined high-frequency transformer can realize automatic production after unifying the size specifications of the winding area 3 and the window size of the magnetic core 41. It can simplify the traditional high-frequency transformer operation process, and realize the integrated mechanical operation of the winding operation of the winding, soldering, magnetic core assembly, magnetic core tape, comprehensive electrical performance test, withstand voltage test, and dipping of insulating varnish.

Abstract

The invention relates to the technical field of electronic product transformer frameworks, and in particular relates to a combined type high-frequency transformer framework. A wire winding region is arranged on a framework body; a magnetic core mounting region is arranged outside the wire winding region; buckling slots, wire hanging convex points and wire penetration slots are arranged on the framework body; the framework body is connected with a base through buckling pieces and the buckling slots which are buckled with each other; a secondary cable socket is connected to the framework body; and terminal pins are inserted into the framework body and are connected with terminal pin connection heads through connection clamps. The combined type high-frequency transformer framework is scientific in structural design; after the size specifications of the wire winding region and a magnetic core window are uniformed, horizontal and vertical frameworks of combined high-frequency transformers can be automatically produced; the working flow of the conventional high-frequency transformer can be simplified; and the wire winding work of windings, soldering, magnetic core assembling, magnetic core glue wrapping, comprehensive electrical performance test, voltage resistance test, insulation paint immersing and the like are integrated and mechanically executed.

Description

Technical field: [0001] The invention relates to the technical field of transformer skeletons for electronic products, in particular to combined high-frequency transformer skeletons. Background technique: [0002] At present, the cost of production labor is constantly rising, and human resources are constantly being lost. Therefore, enterprises need to achieve optimized manufacturing procedures through innovation, and realize mechanized production, improve productivity and reduce staff to increase efficiency. [0003] In the technical field of existing transformer bobbins for electronic products, the bobbins have a single purpose. After the products are eliminated, the supporting coil bobbins and molds are also discarded; when the performance requirements of the same electrical appliances are different in the layout of the electronic circuit board, the transformer needs to be redesigned, resulting in a lot of waste. Time and labor costs; in realizing fully automated producti...
