【発明の詳細な説明】 〔発明の目的〕 （産業上の利用分野） 本発明は環状端子部の外周面に接触子を摺接させて電送
を行なうスリップリング装置に関する。DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial field of use) The present invention relates to a slip ring device for transmitting electric power by bringing a contactor into sliding contact with the outer peripheral surface of an annular terminal portion.
（従来の技術） 従来、固定部から回転部またはその逆方向に電送するも
のとして、第２図に示すように導電性支持体101の外周
側に絶縁部材102を介して複数の環状端子部103を配設
し、個々の環状端子部103にリード線104を接続し回転部
側に導出させたスリップリング装置が知られている。こ
の装置は導電性支持体の連結部101aを回転系（図示せ
ず）の軸端に固定して用いられる。(Prior Art) Conventionally, a plurality of annular terminal portions 103 are provided on the outer peripheral side of a conductive support 101 via an insulating member 102 as shown in FIG. There is known a slip ring device in which a lead wire 104 is connected to each annular terminal portion 103 and is led out to the rotating portion side. This device is used by fixing the connecting portion 101a of the conductive support to the shaft end of a rotary system (not shown).
ところで、ビデオテープレコーダ等においては回転系全
体に存在する外部誘導ノイズによる悪影響を受け易いこ
とから、回転系を接地状態にすることが行なわれてい
る。一般に回転部は軸受により回転自在に支承される
が、いかなる軸受を用いたとしても回転系を完全に接地
することはできなかった。そこで、通常は特別に接地用
端子部を設けるか、あるいは上記のスリップリング装置
の環状端子部103のうち１チャンネル電源GND用として使
用し、接地の意味も含めて兼用することが行なわれてい
る。By the way, in a video tape recorder or the like, the rotating system is grounded because it is easily affected by externally induced noise existing in the entire rotating system. Generally, the rotating part is rotatably supported by bearings, but no matter which bearing is used, the rotating system cannot be completely grounded. Therefore, a special grounding terminal portion is usually provided, or one of the annular terminal portions 103 of the slip ring device is used as a power source GND, and the grounding portion is also used. .
しかしながら、スリップリング装置の環状端子部103を
電源GND用として流用すると、回転系全体に存在する外
部誘導ノイズ、特に高周波領域のノイズを低減させるに
は極めて不十分である。However, if the annular terminal portion 103 of the slip ring device is diverted for the power supply GND, it is extremely insufficient to reduce the external induction noise existing in the entire rotating system, especially the noise in the high frequency region.
このため、現状では機器を構成する際にスリップリング
装置の他に、接地用端子部を別の部所に設けることがな
されている。ところが、接地用端子部を別に設けること
によって部品点数が増えるために、小型軽量、簡略化等
の面からみて不利な点が多い。Therefore, at present, in addition to the slip ring device, the grounding terminal portion is provided at another portion when constructing the device. However, since the number of parts is increased by providing the grounding terminal separately, there are many disadvantages in terms of size, weight and simplification.
（発明が解決しようとする問題点） 上述した如く従来技術によれば回転系に存在する外部誘
導ノイズを十分に低減することができない問題を有して
いる。(Problems to be Solved by the Invention) As described above, according to the conventional technique, there is a problem that the external induction noise existing in the rotary system cannot be sufficiently reduced.
そこで、本発明は上述の問題点に着目してなされたもの
で、回転系を完全な接地状態とし得るスリップリング装
置を提供することを目的とする。Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a slip ring device capable of bringing a rotating system into a completely grounded state.
（問題点を解決するための手段と作用） 本発明は、外周に絶縁部材を介して１個以上の環状端子
部を配設した導電性支持体に、略半球状をなす接地用端
子部を前記支持体の軸心上に一体に設けたものである。(Means and Action for Solving Problems) According to the present invention, a substantially hemispherical grounding terminal portion is provided on a conductive support having one or more annular terminal portions arranged on the outer periphery through an insulating member. It is provided integrally on the axis of the support.
この様な構成によれば、回転系を完全に接地状態にでき

た、接地用端子部は支持体の軸心上である回転系の上部
或いは下部に取付けてあるので、短時間に容易に交換で
きる。With such a configuration, the rotating system can be completely grounded, and the peripheral speed of the grounding terminal can be reduced because the grounding terminal is in contact with the rotating part at one point. The noise of can be reduced. Further, since the peripheral speed of the grounding terminal is low, the life of the grounding terminal can be improved. Further, since the grounding terminal portion is attached to the upper or lower portion of the rotary system which is on the axis of the support, it can be easily replaced in a short time.

In the figure, reference numeral 1 is a support made of a conductive material, and this support 1 is a flange-shaped connecting portion so that it can be fixed to the shaft end of a rotating portion (not shown) with screws or the like.
It has a structure in which a columnar supporting portion 1b is vertically installed at the center of the connecting portion 1a. One or more in the illustrated example, three annular terminal portions 3 are provided on the outer peripheral side of the support portion 1b via an insulating member 2.
Are arranged in three steps with a predetermined interval. Lead wires 4 are connected to the inner peripheral surfaces of these annular terminal portions 3,
Each lead wire 4 is led out to the outside through a through hole 1c formed in the connecting portion 1a along the supporting portion 1b.

In this case, in order to improve wear resistance, carbon is preferably used for the grounding contact (not shown) on the mating side that is electrically connected to the grounding terminal portion 5. In addition,
The grounding contact 5 is not limited to carbon as long as it has good electrical conductivity and excellent wear resistance, and a material that matches the purpose of use and the material of the grounding contactor can be appropriately selected and its shape is also free. Can be changed to
