Abstract

The invention provides a coil frame and a transformer using the coil frame. The coil frame can be used for reasonably dealing with multiple coiling parts with different winding turns or creepage distances. The coil frame has a roll core part (17) the periphery of which is provided with coils (12). The coil frame comprises a first half frame body (13a) and a second half frame body (13b). Each halfframe body (13a,13b) integrally comprises a flange part (terminal seat part 16a), an upper side flange part (16b) and at least two roll core members (17a, 17b) projecting at a right angle from the flange part. Furthermore, each half frame body (13a,13b) is assembled in a way that the roll core members (17a,17b) intersect between the two half frame bodies (13a,13b) and the flange parts slide alongthe direction where the flange parts are close to each other. Thus a cylindrical roll core part (17) is formed.

Description

technical field [0001] The present invention relates to a bobbin and a transformer using the bobbin, in particular to a bobbin capable of dealing with winding components such as various transformers or inductors with different numbers of winding turns or creepage distances, and a bobbin using the bobbin the transformer. Background technique [0002] Conventionally, there is known a transformer that can use a bobbin whose height can be adjusted (same as in the longitudinal direction, hereinafter the same), and one type of bobbin can be used for a variety of transformers (for example, refer to Patent Document 1). [0003] With regard to the transformer known in Patent Document 1, the skeleton main body and the base part forming the skeleton are separated from each other, and a plurality of annular recesses or external threads are formed on the outer periphery of the lower end part of the cylindrical part of the skeleton main body. In the support hole of the base portion throu...
