Abstract

An adhering process of adhering a winding, after the winding is wound on the bobbin, to a bobbin entirely or partly with an adhesive tape, for the purpose of reliably fixing the winding to the bobbin, increases the manufacturing cost of a transformer. To solve this problem, a primary winding (13) is wound on a winding core (111). Extracting portions of the primary winding (13) are caused to intersect, and their terminal ends are connected to terminals (14) which oppose each other through the winding core (111) and which are arranged within a region having end portions of a winding space of the winding core (111) as boundaries.

Description

Background of the invention

[0001] The present invention relates to electronic components, such as transformers and inductors, and methods of manufacturing the same.

[0002] figure 1 Is the structural diagram of the transformer winding section. Such as figure 1 As shown, after the electric wire (winding) 3 is wound on the bobbin 1 of electrical insulating material, in order to securely fix the winding 3 on the bobbin 1, the whole or part of the winding 3 is stuck on the bobbin 1 with adhesive tape 2 . If the number of turns of the winding 3 is sufficient, the winding 3 can hold the bobbin 1 , but if the number of turns is small (for example, 1 turn), the winding 3 is difficult to fix on the bobbin 1 . Therefore, it is very important to stick the winding 3 to the bobbin 1 by the tape 2 or the like.

[0003] In order to apply the adhesive tape 2 , a wide winding space is required in the coil former 1 . As a result, a coil former 1 with a large winding space is required, re...
