Problems solved by technology

[0008] However, in the technology of the above-mentioned patent publication, both ends of the winding portion for winding the coil are provided with the bobbin having the collar portion, and since the height dimension of the bobbin and the height dimension of the iron core are added, it is not enough for the coil winding. component height, so there is a limit to its thinning

Embodiment Construction

[0016] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0017] Such as figure 1 and figure 2 As shown, the first iron core 11 is formed of a material with low electrical insulation, such as a manganese-based ferrite material, and has an insertion portion 12 at both ends, and a flat rectangular shape with a coil wound in the middle. The coil winding part 13.

[0018] The terminal block 14 is composed of a pair of left and right with the same structure, and the terminal block 14 is composed of a core mounting portion 15 and a terminal mounting portion 16 provided integrally with the core mounting portion 15 . Fitting holes 17 are provided on the inner surfaces of the core mounting portions 15 facing each other, and the first core insertion portion 12 is inserted into the fitting holes 17 and bonded with an adhesive.

[0019] Furthermore, a plurality of connection terminals 18 protrude upward from the upper surface of the terminal m...

Abstract

Provided is a thin coil-wound component in which the thickness can be reduced and the workability of coil winding work and assembling work can be enhanced. The thin coil-wound component is provided with a first core 11 having a part 13 on which a coil 20 is to be wound, a terminal block 14 for coupling the opposite end parts of the first core 11 and provided with an upward fitting groove 21 in the lower surface, a terminal 18 for connection with the coil provided on the terminal block, and a second core 22 having an upper opening circumferential wall part 23 surrounding the coil winding part of the first core and provided, at the opposite ends thereof, with piers 25 being fitted in the fitting groove of the terminal block.

Description

technical field [0001] The present invention relates to a thin coil wound part, such as a transformer and a trigger coil used in optical devices such as cameras and small electronic devices. Background technique [0002] In order to place small transformers used in optical devices such as cameras and small electronic devices in the limited space of small electronic devices, miniaturization and thinning are required. [0003] Therefore, in order to meet the aforementioned requirements, as described in Japanese Patent No. 2874707, JP-A-7-220945, JP-3368826, JP-2000-277340 and JP-5-17687 , It is proposed to reduce the thickness of coil package parts such as transformers and trigger coils. [0004] The aforementioned Patent No. 2874707 has: a bobbin having terminal mounting portions on both sides of a winding portion for winding a coil; a first iron core disposed inside the winding portion; and a second iron core disposed so as to surround The outer circumference of the above-...
