Description

technical field [0001] The invention relates to a transformer structure, in particular to a transformer structure with an insulating base body. The invention also relates to an insulating base for a transformer structure. Background technique [0002] Transformer is a common magnetic component in electrical equipment. It uses the principle of electric energy and magnetic energy conversion induction to adjust the voltage so that the voltage reaches the applicable range of electrical equipment. [0003] see figure 1 , which is a schematic structural diagram of a known transformer. Such as figure 1 As shown, the transformer 1 includes a winding frame 10, the primary winding and the secondary winding (not shown) are wound on the winding frame 10, and an insulating tape 12 is coated on the primary and secondary windings. The first wire outlet 131 of the secondary winding can be wound on the pin 101 extending from the winding frame 10 , and the second wire outlet 141 of the se...

Problems solved by technology

[0004] However, because the known transformer 1 is wound with several layers of insulating tape 12 around the periphery, the step of winding the insulating tape 12 is not only labor-intensive, but also the volume of the transformer 1 will increase due to the winding of the insulating tape 12, and the appearance is not easy to control. Therefore, when the transformer 1 is installed When placed on a circuit board (not shown), it will negatively affect the overall layout of the circuit board

For example: the protruding corner 121 of the insulating tape 12 relative to the transformer 1 may press the adjacent electronic components on the circuit board, and the transformer 1 will also touch other electronic components on the circuit board due to the increase in volume, and because the transformer 1 The first outlet end 131 of the main-level winding wire must be wound on the pin 101 of the winding frame 10, which is not only difficult to arrange the wire, but also easily touches each other or adjacent electronic components due to the large winding volume of the wire. This will cause a short circuit

In addition, the first outlet 131 of each primary winding of the known transformer 1 must be additionally sheathed with a sleeve 132 to prevent the first outlets 131 from overlapping and crimping each other, and to avoid contact between the first outlet 131 and the pin 101. During soldering, tin channeling occurs and the insulating layer of the primary winding is scalded, but the manufacturing process for the first outlet end 131 of the primary winding to cover the sleeves 132 is cumbersome, and the manufacturing cost of the transformer 1 will be relatively increased; Since the second outlet end 141 of the secondary winding is a flying lead, when the transformer 1 is arranged on a circuit board (not shown), there are also problems such as difficult positioning and difficult corresponding insertion into the default socket on the circuit board.
