Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the structure of a winding frame with a pin terminal for an inductance element that can be stabilized on a substrate.

[Conventional technology]

The structure of a conventional winding frame with a pin terminal includes flanges 22, 2 that project outward at both ends of a cylindrical winding core 21, as shown in the perspective view of FIG. 3 and FIG. 4, which is a sectional view thereof.
3, a plurality of pin terminals 27 are implanted in the collar 32 perpendicularly to the board 33 installed on the winding frame with pin terminals, and the other collar 23 is
The end of the U-shaped coil is passed through the edge of the U-shaped coil perpendicularly to the substrate 33 to form a one-turn coil 8. Furthermore, the intactance element is constructed by winding the winding 29 on the winding frame with the pin terminal, connecting the end of the winding to the pin terminal 7 and soldering it, and then attaching the I-shaped core 30 to the I-shaped core 30.
is inserted into the center hole 26 of the winding core 21, and the U-shaped core 31 is inserted from above along the core guide grooves 25, 25', butted against the I-shaped core 30, and fixed with the core holding fitting 32 to be assembled. .

[Problem that the invention attempts to solve]

However, in the case of a winding frame with a pin terminal of this structure, since the U-shaped one-turn coil 8 is in the same direction as the pin terminal 27, the lead wire 16 is attached to the one-turn coil 8.
When wiring, there is a drawback that the winding frame with pin terminals must be mounted on the board 33 and then connected to the lead wire 36 via the back pattern 34 provided on the board 33.

The present invention was devised in view of the above-mentioned circumstances, and its purpose is to provide a winding frame with a pin terminal that allows a lead wire to be wired directly to a one-turn coil.

[Means for solving problems]

The present invention consists of a winding frame made of an insulating material that has outwardly projecting flanges at both ends of a cylindrical winding core, and a plurality of pins attached to one of the flanges along opposite sides parallel to the board to be installed. In a winding frame with a pin terminal in which a terminal is planted and the end of the U-shaped coil is passed through the other flange to form a one-turn coil, the U-shaped coil is placed parallel to the substrate. A one-turn coil is formed by penetrating the flange, and a support terminal to be attached to the substrate is implanted along the opposite side parallel to the substrate of the flange through which the coil passes.

[Example of idea] Examples of the present invention will be described below.

1 and 2 are diagrams in which an inductance element using a winding frame with a pin terminal according to the present invention is installed on a substrate.

In the figure, the winding frame with pin terminals is a winding frame made of an insulating material that has flanges 2 and 3 at both ends of a cylindrical winding core 1, and pin terminals 7 and 7' are attached to the edges of the flanges 2 and 3 along opposite sides. A total of four coils are installed in each case, and the end of a one-turn coil 8 as shown in FIG. 3 is passed through the collar 3 parallel to the board on which it is installed. The inductance element is manufactured by winding 9 on this winding frame with a pin terminal, connecting the end of the winding 9 to the pin terminal 7 and soldering it, and then passing the I-shaped core 10 through the center hole 6 of the winding core 1. , Insert the U-shaped core 11 from above along the core guide grooves 5, 5', butt it against the I-shaped core 10, and fix both cores with a core holding fitting, and assemble.
attached to the board.

With the above structure, the lead wire 16 can be directly connected to the U-shaped one-turn coil 8, and the surface is also stable. Note that since the pin terminal 7' is not used for electrical connection, other supports may be used;
It is effective to fix it with

[Effect of idea]

As explained above, with the structure of the present invention, the lead wire can be connected directly to the U-shaped one-turn coil, and since there is no need to use a large back pattern on the board, the board can be made smaller, reducing costs. An inductance element with .
