【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、電子機器の内部における回路接続に用いるコ
ネクタに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connector used for circuit connection inside an electronic device.

品は、回路から発生する雑音の発射源となる事か多く、
その雑音を抑制する為に、第３図に示すように、環境の
フェライトコア１１に電線１２を貫通させた構造にする
ことて効果が得られていた。(Prior Art) Conventionally, connecting parts composed of electric wires and connectors that connect printed wiring boards to each other or printed wiring boards and electronic components often become a source of noise generated from the circuit.
In order to suppress the noise, an effect has been obtained by creating a structure in which an electric wire 12 is passed through a ferrite core 11 in the environment, as shown in FIG.

If these parts are not required, there is a problem in that the cost of the connecting parts increases. In addition, the ferrite core 11, which is formed by sintering ferrite powder, is prone to cracking and chipping due to mechanical shock. It is necessary to fix the ferrite core 11 to a housing or the like, or to protect the ferrite core 11 itself.
そこて本発明は、これらの問題点を無くして雑音発生の
対策を可能としたものである。Therefore, the present invention eliminates these problems and makes it possible to take measures against noise generation.

ライトコア２１と信号線の関係は第２図による。FIG. 1 is an external view of a connector according to the present invention, and FIG. 2 is a sectional view. In FIG. 1, a square ferrite core 21 is press-fitted into a female connector housing 22 which is inserted and connected to a male connector 23 mounted on a printed wiring board. The female connector housing sink is made of resin molding.
By providing a slight protrusion on the side surface, the ferrite core 21 can be fixed by press fitting. The relationship between the ferrite core 21 and the signal lines is shown in FIG.

パターンと、随時接続の開閉かてきる。The male connector 23 includes a male terminal 32 connected to a pattern on a printed wiring board 31, and a resin-molded connector base 23a that insulates and holds the male terminal 32. At the tip of the electric wire 12 serving as the signal line, there is a female terminal 3 that fits into and makes contact with the male terminal 32.
3 are connected, and when the female terminal 33 is inserted into the connector housing sink 22, it is fixed to the connector housing sink 22. With this structure, the connection parts consisting of the electric wire 12, the female terminal 33, and the connector housing sink 22 can be connected or closed according to the pattern of the printed wiring board 31 at any time.

である。Further, the signal line connected by the above structure passes through the ferrite core, and the arrangement of the ferrite core can be realized only by press-fitting a resin part (not shown). In addition, in FIGS. 1 and 2, the effect is the same even if the ferrite core 21 is fixed to the connector housing sink 22 or the ferrite core 21 is fixed to the connector base 23a.
