Description

[Detailed explanation of the invention] A. Purpose of the invention [Industrial application field] This invention consists of forming a toroidal coil formed by winding a wire around a ring core, and soldering the lead wire of the toroidal coil to a pin terminal provided on a base. This invention relates to a base with pin terminals for toroidal coils.

[Conventional technology]

Conventionally, toroidal coils are made by winding a ring core, fixing the toroidal coil alone on a board with a presser plate, and then passing a screw through the center hole of the toroidal coil and mounting it on the board. Because of this structure, if the wire diameter of the winding is small, it may break due to impact after being mounted on the board, and the mounting area on the board becomes large.

[The problem that the idea attempts to solve]

The present invention has a toroidal coil mounting structure in which the toroidal coil is placed vertically, which reduces the board mounting area and prevents the lead terminal from breaking even if a slight impact is applied on the mounting board. To provide a base with pin terminals for toroidal coils.

B. Structure of the invention [Means for solving the problem] In order to mount a toroidal coil on a board, the present invention has a male and female structure in which the coil is fixed at the center of a holding plate and two separate holding plates are fitted together. Attach the central shaft of the holding plate, attach a collar with a standoff and terminals attached to it for board mounting to one end of the holding plate, hold the toroidal coil between the two holding plates, and then attach the outer side of the two holding plates. This is a base with pin terminals for toroidal coils that is fixed using U-shaped metal fittings.

That is, in the present invention, a base is provided with a male and female structure central shaft at the center, and a flange with pin terminals and standoffs on the lower end side is attached, and the base is fitted by the central shaft with the toroidal coil facing each other. This is a base with a pin terminal for a toroidal coil, characterized in that the top of the base is fixed with a U-shaped metal fitting.

[Effect]

At the center of each of the holding plates that press and support the toroidal coil from both sides of the toroidal coil, a central shaft with a male and female structure that fits into each other is attached. The toroidal coil is fixed by inserting the shaft into the center hole of the toroidal coil, and when the center shafts are fitted together, the center shafts are glued together with resin and fixed, and the two holding plates are fixed with their tops in place. Fix it with the shape metal fittings.

The lead wire of the toroidal coil is fixed to the pin terminal 5 inside the standoff. There are four pin terminals, two on each holding plate, and the coil is fixed on the board using the four pin terminals. In the present invention, the central axis of the presser plate has a male and female structure and is expandable and retractable in the coil width direction, so it can be easily applied even to toroidal coils having different coil widths.

〔Example〕

A toroidal coil 10 having a wire wound around a ring core is held from both sides by a holding plate 1a having a female center shaft 2a, a collar 3a, and a pin terminal 5, and a holding plate 1b having a male center shaft 2b, a collar 3b, and a pin terminal 5. Fit and sandwich the center shaft, and fix by soldering the four pin terminals of the base and the two lead terminals of the toroidal coil.

The center shafts of the pressing plates are coated with thermosetting resin and fitted together when assembled, and the tops of the two pressing plates are fixed with U-shaped metal fittings. The base with pin terminals of the present invention has a structure in which the pin terminals are attached to the four corners of the base when the toroidal coil is combined, so it can be stably fixed on the board, and the coil lead terminals are attached to the pin terminals in advance. Because the structure is fixed, there is no risk of the lead terminals being cut off even if subjected to vibration after mounting on the board.Also, the toroidal coil is installed vertically and is mounted in the width direction of the toroidal coil, so there is no risk of the lead terminal breaking on the board. The mounting area of is a small value.

C. Effects of the invention By using a base with pin terminals for toroidal coils, there is no breakage of lead terminals due to impact compared to conventional mounting soldering alone.
Moreover, the mounting area of the board can be reduced.
