Abstract

PURPOSE:To obtain inductance parts which are good in mounting efficiency and have small mounting areas and causing no possibility of deficiency of parts mounting spaces by arranging in parallel with each other a plurality of beads core elements respectively provided with terminals in the length direction of beads cores and forming the elements to one body with a resin. CONSTITUTION:A plurality of beads core elements 1 composed of two parallel lead wires which are passed through through-holes provided in the length direction of beads cores 4 and one ends of which are short circuited, with the other ends being used as terminals, are arranged in parallel with each other, with the terminals 3 of each elements protruding in the same direction, and the elements 1 are formed to one body with a resin. Since the plurality of beads cores 1 are united to one parts with the resin in such way, the parts can be mounted on a substrate at a less number of mounting times even when a plurality of signal lines exist on the substrate. Therefore, inductance parts which are good in mounting efficiency and have small mounting area and causes no possibility of deficiency of parts mounting spaces can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an inductance component mounted on a substrate for high frequency noise countermeasures.

[Conventional technology]

As shown in FIG. 3, the conventional inductance component has a shape in which lead terminals 12 are provided coaxially with the core 11 at both lengthwise ends of a bead core 11, and these are bent at right angles in the same direction. . This component is mounted on the signal line on the board to absorb and remove high frequency noise from the signal line.

[Invention or problem to be solved]

However, conventional inductance components have the following problems. That is, (1) If there are multiple signal lines on a board, one conventional inductance component must be mounted on each line. For this reason, the number of implementations increases,
Poor implementation efficiency.

(2) Furthermore, when a conventional inductance component is mounted on a board, the long bead core 11 is placed parallel to the board. For this reason, the mounting area for the inductance component becomes large, and the mounting space for other components is compressed.

This invention was made in order to solve these conventional problems, and it provides an inductance component that can be mounted less often, has high mounting efficiency, and has a small mounting area, so it does not occupy the mounting space of other components. The purpose is to provide

(Means for solving the problem) An inductance component according to the present invention includes a bead core,
A plurality of bead core elements each consisting of two parallel T-wires are inserted into the through-hole in the longitudinal direction, one end is shortened, and the other end is a terminal.The terminals of each element are connected in the same direction. It is made to protrude and is integrally molded with resin.

[Effect]

In the inductance component of the present invention, a plurality of score elements are assembled into one component using resin, so even if there are multiple signal lines on the board, the number of mounting steps can be reduced.

Furthermore, when the inductance component of the present invention is mounted on a substrate, the long bead core is placed vertically on the substrate, so the mounting area of the component is reduced.

(Example) An embodiment of the present invention will be described below.

The inductance component of the example is as shown in FIG.
In the case of a structure in which four bead core elements 1 are integrally molded by resin molding in the bead core 4 portion described later, 2 is a resin molding material molded into a rectangular parallelepiped,
3 is a terminal of the element 1 protruding from the lower end surface of the resin molding material 2 in the same direction.

In the bead core element 1, 4 is a bead core and 5 is a lead wire. The two lead wires 5.5 are inserted loosely into two parallel through holes provided in the length direction of the bead core 4, one end is short-terminated with the same wire material 5a as the lead wire 5, and the other The end portion is the terminal 3. Each bead core element 1
are arranged at equal intervals with the terminals 3 facing the same direction, and are integrally molded in this state. Therefore, the terminals 3 of each element 1 protrude in the same direction from the lower end surface of the resin molding material 2, as described above.

Next, the operation based on the above configuration will be explained.

The above inductance components are combined into one component by four bead core elements 1 or resin molding material 2, so if there are multiple signal lines on the board, four bead core elements 1 can be mounted at a time. I can do it. Therefore, the number of times components are mounted on the board is reduced, and the mounting efficiency is improved accordingly.

Furthermore, since the inductance component protrudes in the length direction of the terminal 3 or the bead core 4, when mounted on the board, the long bead core 4 is placed vertically on the board. Therefore, the mounting area of the component is smaller than before, and the mounting space for other components is not compressed accordingly.In the above embodiment, a rectangular parallelepiped bead core 4 with two through holes is used. As shown in FIG. 2, a pair of hollow cylindrical bead cores 6 and bead cores 7 having different magnetic permeabilities may be used. By using both cores 6.7, it is possible to obtain an inductance component having frequency characteristics in a wider band than in the above embodiment.

(Effects of the Invention) As explained above, according to the inductance component of the present invention, a plurality of bead core elements each having a terminal provided in the length direction of the bead core are arranged in parallel and integrally molded with resin. You can get the following effects.

(1) The number of times of mounting is reduced, which improves mounting efficiency.

(2) The mounting area is small, so there is no risk of compressing the mounting space of other components.
