量産には適しない。 Conventionally, in order to block interference radio waves such as high frequencies,
The parts that generate interference radio waves, the casing that absorbs or generates interference radio waves, or electric wires such as multi-core cables, etc.
A method of surrounding the entire part, casing, and electric wire with a conductive metal piece or metal net, or a method of forming a conductive layer inside the plastic casing in addition to surrounding it with the metal piece or metal net in a plastic casing. Electromagnetic shielding was performed. However, when transmitting and receiving signals, electromagnetic shielding has been neglected at the electrical connections in the relay section or the unprocessed end section. If there is no shielding around these devices, electromagnetic noise often enters through the wires or connectors through extremely small gaps where electromagnetic shielding is difficult, causing electronic devices to malfunction. Therefore, in order to prevent this noise from entering, especially in a ready-made connector part, a metal frame, for example, is placed around the ready-made connector 2 housing the terminal 1.
Measures are taken to surround the plastic connector 2 with a shielding protective cover such as the one shown in FIG. In order to shield the connector 5 and the connector 2, two or more parts are required with a split structure so that they can be attached from the outside. In many cases, mass productivity becomes poor and production costs become high. In addition, a conductive layer is further formed on the surface of the plastic connector 2.
Cracks and peeling of the conductive layer are likely to occur, and when the conductive layer is peeled off, the conductive layer is exposed and short-circuits the electric circuit. In addition, it is complicated to fabricate a conductive layer by secondary processing an already made plastic connector, making it unsuitable for mass production.
そこで、既製のコネクタ２への雑音防止のため
導電性を有する樹脂カバーで該コネクタ２を蔽う
ことが望まれていたが、一般に導電性樹脂として

遮蔽効果は余り期待できない。 Therefore, it has been desired to cover the connector 2 with a conductive resin cover in order to prevent noise from entering the ready-made connector 2. However, although some conductive resins are generally mixed with carbon-based filler, etc. I can't expect much of an effect.

カバーを要旨としている。 The present inventor discovered that short fibers of conductive metals, particularly aluminum, with a fine cross section have recently become available at relatively low prices.
The present invention was achieved from the viewpoint that when these short fibers are dispersed in a synthetic resin film, the fibers are intertwined with each other and the entangled body forms an electrical shield. A cover that shields the entire connection part consisting of an electric wire and a part of the electric wire following this electric wire, in which a large number of conductive metal short fibers, ribbons, or flakes are entangled with each other inside the resin. An electrical connection part characterized in that the electrical terminal is connected to the entangled body of conductive materials and protrudes from the outer surface of the resin, and the resin is molded into a thin hollow body shape using a soft resin. The gist is the shielding cover.

の遮蔽カバーの製造法を要旨としている。 The present invention also relates to a method for manufacturing a shielding cover for the electrical connection part, wherein the plurality of conductive metal short fibers, ribbons, or flakes are made to have a volume resistivity of at least 1 Ωcm or less. A ready-made connector, an electric wire to be connected to it, and a wire following this electric wire are placed in a sol-like resin bath in which they are mixed in an entangled state at a volume ratio and the entangled bodies are uniformly dispersed. A lead wire of an electrical terminal is immersed in a mold that covers the entire connection part consisting of a part of an electric wire, and the mixed resin is adhered to the mold and pulled out, and then the adhering resin is melted and gelled. The gist of this paper is a method for manufacturing a shielding cover for electrical connections, in which a gelled mixed resin is cooled and then removed from a mold to obtain a soft resin molded product.
導電性プラスチツクの電磁遮蔽効果SEをdBで
表わせば、次式の関係がある。 If the electromagnetic shielding effect SE of conductive plastic is expressed in dB, there is the following relationship.
SE＝Ｒ＋Ａ ………(1)
ここに
Ｒ＝50＋10log（ρ・ｆ）-1
Ａ＝1.7t＋（ｆ／ρ）1/2
で、Ｒは反射による減衰（dB）、Ａは吸収による
減衰（dB）、ρは体積固有抵抗（Ωcm）、ｆは周
波数（ＭHz）、ｔは厚み（cm）である。(1)式から
体積固有抵抗値ρの小さい方が遮蔽効果が大きい
ことがわかる。又、実装可能なSE値は周波数に
より若干変わるが、実験の結果30dB以上で、体
積固有抵抗値は100Ωcm即ち１Ωcm以下が望まし
い。 SE=R+A......(1) Here, R=50+10log(ρ・f) -1 A=1.7t+(f/ρ) 1/2 , R is attenuation due to reflection (dB), A is attenuation due to absorption ( dB), ρ is the volume resistivity (Ωcm), f is the frequency (MHz), and t is the thickness (cm). From equation (1), it can be seen that the smaller the volume resistivity value ρ, the greater the shielding effect. Furthermore, the SE value that can be implemented varies slightly depending on the frequency, but as a result of experiments, it is desirable that it is 30 dB or more, and the volume resistivity value is 10 0 Ωcm or less, that is, 1 Ωcm or less.
上記体積固有抵抗を得るためには、例えば繊維

加と製品遮蔽カバーの非柔軟性化の増加の問題が
ある。前記アルミニウムの細繊維素材を用いた場
合、実験の結果少くとも１Ωcmの体積固有抵抗値
を得るために上記の容積比が求められた。 In order to obtain the above-mentioned volume resistivity, it is preferable that the volume ratio of the fibrous conductive material to the electrically insulating soft resin material is at least 15%, but the conductivity of the conductive material is different. When selecting a material, it is necessary to increase or decrease the volume ratio depending on the electrical conductivity.
However, if there is a large amount of conductive material mixed in, the volume resistivity of the shielding cover made of electrically insulating soft resin will be lower due to the material mixture, but the weight will increase due to the mixing of the material and the product shielding cover will become less flexible. There is a problem. In the case of using the aluminum fine fiber material, the above volume ratio was determined in order to obtain a volume resistivity value of at least 1 Ωcm as a result of experiments.

A sol-like resin liquid 21 is prepared by mixing 15% of the volume of the liquid with an aluminum material having a length of 2 to 3 mm. A propeller 23 provided at the end of the shaft immersed in the aluminum material 21 is rotated to stir the aluminum material 24 so that it is uniformly dispersed in the sol-like resin liquid 21. The side surface of a shamisen plucked-shaped mold 25 with thick claws to cover the entire connection part consisting of a ready-made connector, an electric wire connected to it, and a part of the electric wire following this electric wire. After a part of the terminal lead wire 28 is fixed to a stopper 29 provided in the mold 25 and the mold 25 is preheated to 130 to 180° C. in a preheating furnace, the mold 25 is immersed in a sol-like resin liquid 21. In this case, the stopper is not immersed, but the lead wire 2
Immerse the tip of No. 8 thoroughly. Sol-like resin liquid 21
After adhering to the outer surface of the mold 25, the mold was pulled up from the sol-like resin liquid 21, and the mold 25 with the sol-like resin liquid 21 adhering to it was heated again in the furnace to 180 to 200°C to make it adhere. The sol-like resin liquid 21 is gelled, and then cooled. In this case, a portion of the lead wire 28 is inside the resin during cooling, and as the resin solidifies, it is fixed to and integrated with the resin. After cooling, the resin is removed from the mold 25 by air blowing to obtain the shielding cover 10 made of soft resin.

The tangled body of fibers has a volume resistivity value of 10 0 to 10 −1 Ωcm and serves as an electromagnetic shield. However, since the grounding terminal lead wire 28 is electrically connected to the resin, this shielding cover ensures that the electric wire 4, the electric wire 5, and the ready-made connector 2 are completely electromagnetically connected at the same potential as the earth. shielded. Therefore, there is no interference such as noise from any small gap between the connecting parts of the connector. Since it is flexible, it can be used immediately in ready-made connectors as long as its inner dimensions are approximately the same, thereby protecting the connector from noise and the like. Incidentally, since the shielding cover receives the force applied to the electric wire at the intermediate portion between the connector and the electric wire, there is also an effect of preventing the electric wire from being cut.

Since it will be connected to the body, there is no need to add any special attachment means other than dip molding.

A shielding cover for an electrical connection part, characterized in that it is formed into a hollow body shape. 2 A large number of conductive metal short fibers, ribbons, or flakes are mixed in an entangled state at a volume ratio that provides a volume resistivity of at least 1 Ωcm or less, and the entangled body is uniformly dispersed. Electrical terminal leads are placed in a mold shaped to cover the entire connection area, which consists of a ready-made connector, an electric wire to be connected to it, and a part of the electric wire following this electric wire in a bath of sol-like resin. The mixed resin is attached to the mold by dipping with a wire and pulled up, the attached resin is melted and gelled, and the gelled mixed resin is cooled and then removed from the mold to form a soft resin molded product. A method of manufacturing a shielding cover for electrical connections to obtain.
