本考案はスリップリングに係り、特に光波測距装置の搭載された測量機の望遠 鏡等に使用され、望遠鏡回転部と本体固定支持部との電気的接続を確実かつ容易 に実現するようにしたスリップリングに関する。 INDUSTRIAL APPLICABILITY The present invention relates to a slip ring, and is particularly used for a telescope of a surveying instrument equipped with a lightwave distance measuring device, so that an electrical connection between a rotating part of the telescope and a fixed supporting part of the main body can be reliably and easily realized. Regarding slip rings.
【０００２】[0002]
従来、光波測距部の搭載されたＥＤＭセオドライトやトータルステーションで は、測量機の望遠鏡部と本体との電気的接続を行うために所定のトラック数から なるスリップリングが望遠鏡回転軸に設けられている。 図６は、測量機の望遠鏡部に用いられている従来のスリップリングの一例を示 したものである。同図において、符号５１は望遠鏡の回転軸を示しており、この 回転軸５１はスラストリング５２により本体側の軸受５３に回転自在に保持され ている。さらに回転軸５１の端部には略筒状の端子部材５４が螺着されている。 この端子部材５４は樹脂によるインサートモールド成形品で、胴部には一例とし て６本の導電リング５５が所定の間隔をあけて形成されている。この導電リング ５５は銅製の円環状部材をあらかじめ所定間隔で型内に配置し、樹脂を流し込む 一体成形によりリング外周面が端子部材５４の胴部５４ａの表面に現れるように したものである。 Conventionally, in EDM theodolites and total stations equipped with a light wave distance measuring unit, a slip ring consisting of a predetermined number of tracks is provided on the telescope rotating shaft to electrically connect the telescope unit of the surveying instrument to the main body. . FIG. 6 shows an example of a conventional slip ring used in the telescope section of a surveying instrument. In the figure, reference numeral 51 indicates a rotary shaft of the telescope, and the rotary shaft 51 is rotatably held by a bearing 53 on the main body side by a thrust ring 52. Further, a substantially cylindrical terminal member 54 is screwed onto the end of the rotary shaft 51. The terminal member 54 is an insert-molded product made of resin, and as an example, six conductive rings 55 are formed on the body portion at predetermined intervals. The conductive ring 55 is made of copper-made annular members arranged in a mold at a predetermined interval in advance, and the resin outer surface is integrally molded so that the outer peripheral surface of the ring appears on the surface of the body 54a of the terminal member 54.
【０００３】 このとき図７に示したように各導電リング５５の内周部分５５ａには電気通信 用ケーブル５６の導線の先端５６ａが直に半田付けされている。そして複数の導 電リング５５にそれぞれ接続された複数の電気通信用ケーブル５６は、接続部が 端子部材５４内に一体的に埋設され、前述の樹脂製の端子部材５４の内側端面か ら複数のケーブル線が延出し、望遠鏡内の所定箇所に配線されるようになってい る。At this time, as shown in FIG. 7, the tip 56a of the lead wire of the telecommunication cable 56 is directly soldered to the inner peripheral portion 55a of each conductive ring 55. A plurality of electric communication cables 56 respectively connected to the plurality of conductive rings 55 have a connecting portion integrally embedded in the terminal member 54, and a plurality of electric communication cables 56 are formed from the inner end surface of the resin-made terminal member 54. A cable line extends and is routed to a predetermined place inside the telescope.
【０００４】 一方、導電リング５５の接触子として針金状の導電ブラシ５７が導電リング５ ５の表面に形成された円周状溝の一部に接触して電気通信用ケーブル５６と接続 ケーブル５８との電気的接触を可能にしている。On the other hand, as a contact of the conductive ring 55, a wire-shaped conductive brush 57 comes into contact with a part of the circumferential groove formed on the surface of the conductive ring 55 to connect the electric communication cable 56 and the connection cable 58. It enables electrical contact.
【０００５】[0005]
しかしながら、前述のケーブル線を一体成形した樹脂製の端子部材ではインサ ートモールド成形の前にあらかじめ各導電リングの内周面に複数のケーブル線を 半田付けしなければならず、さらに端子部材を形成するのに導電リングを樹脂で 一体成形するため射出成形時の熱作用により接続箇所等の破断が生じ易い。 その上接続部分が埋設されるので、導通不良の際にその箇所を目視によりすぐ に確認できないという問題がある。 However, in the case of the resin-made terminal member integrally molded with the above-mentioned cable wire, a plurality of cable wires must be soldered to the inner peripheral surface of each conductive ring in advance before the insert molding, and the terminal member is further formed. However, since the conductive ring is integrally molded with resin, the connection portion and the like are likely to break due to the thermal action during injection molding. In addition, since the connection part is buried, there is a problem that the part cannot be visually confirmed immediately in the case of poor continuity.
【０００６】 また、このような導通不良箇所が１箇所でもあれば、端子部材をまるごと取り 替え、すべての配線について再結線しなければならずメンテナンス上、大変面倒 である。 さらに、電気通信極数を現状の接点数から増やすような場合には端子部材の導 電リング数の多いタイプのものを別途製造して対応しなければならず、コストが かかるという問題もある。Further, if there is even one such defective conduction point, it is necessary to replace the entire terminal member and reconnect all wirings, which is very troublesome in terms of maintenance. Further, in the case of increasing the number of telecommunications poles from the current number of contacts, it is necessary to separately manufacture a terminal member having a large number of conductive rings and handle it, which causes a problem of high cost.
【０００７】 そこで、本考案の目的は上述した従来の技術が有する問題点を解消し、 製造 時にケーブルの破断等の不良が発生せず、また容易に接合不良箇所等を発見でき 、容易に電気通信極数の変更を行えるスリップリングを提供することにある。Therefore, the object of the present invention is to solve the above-mentioned problems of the conventional technology, to prevent defects such as breakage of cables during manufacturing, to easily find defective joints, etc. It is to provide a slip ring capable of changing the number of communication poles.

本考案によれば、導線束を案内する導線挿通孔と複数の端子板をそれぞれ独立 して収容可能な端子板収容孔とを長手方向に設けた絶縁端子部材を回転軸の端部 に固着し、導電リングに円周状肩部を介して外周フランジを一体的に形成すると ともに内周縁の一部に前記端子板を一体的に屈曲形成し、該端子板を前記端子板 収容孔内にそれぞれ独立して延在させ、その一部が前記端子部材の端面から突出 するように前記端子板の位置をずらして配置して前記端子部材の胴部に外嵌し、 これと同時に前記端子部材の長手方向に対して前記導電リングが所定間隔で配置 されるように前記端子部材の胴部に前記各導電リングの円周状肩部が形成する各 導電トラックを互いに絶縁する絶縁スペーサを外嵌し、前記導電トラックの一部 に連続的に接触して該導電トラックとの間に電気的接続を可能にする導電接触子 を固定部に設けたので、電気通信用ケーブルを端子部材の外部に突出した端子板 に結線でき、接続不良箇所等の発見を容易に行うことができる。 According to the present invention, an insulating terminal member provided with a conductor wire insertion hole for guiding a conductor wire bundle and a terminal plate accommodating hole capable of accommodating a plurality of terminal plates independently in the longitudinal direction is fixed to the end of the rotary shaft. , The conductive ring is integrally formed with an outer peripheral flange via a circumferential shoulder portion, and the terminal plate is integrally bent and formed in a part of the inner peripheral edge, and the terminal plate is respectively inserted in the terminal plate accommodation holes.

Can be done easily.
【００１０】 また、成形加工による熱作用等の悪影響を受けることがなく、端子部材の品質 低下を防止することができる。さらに同形の導電リングを絶縁部材を介して複数 枚積層して導電トラックを構成するようになっているので、電気通信用の極数の 変更を端子部材等の型を変更したりせずに、容易に行うことができる。Further, the quality of the terminal member can be prevented from being deteriorated without being adversely affected by the heat effect and the like due to the molding process.

【００１１】[0011]
以下本考案によるスリップリングの一実施例を図１乃至図４を参照して説明す る。 図１は、本考案によるスリップリングを光波測距装置を搭載した測量機の望遠 鏡と本体との電気的接続に用いた一例を示したものである。同図において、符号 １２は光波測距装置の搭載された望遠鏡の回転軸（水平軸）を示しており、この 回転軸１２はスラストリング３０により本体側の軸受３１に回転自在に保持され ている。 An embodiment of the slip ring according to the present invention will be described below with reference to FIGS. FIG. 1 shows an example in which the slip ring according to the present invention is used for electrical connection between a telescope and a main body of a surveying instrument equipped with an optical distance measuring device. In the figure, reference numeral 12 indicates a rotary shaft (horizontal shaft) of a telescope on which the optical distance measuring device is mounted, and the rotary shaft 12 is rotatably held by a bearing 31 on the main body side by a thrust ring 30. .
【００１２】 さらに回転軸１２の端部には軸方向に複数の導電リング１が積層された略筒状 の端子部材４がネジ部１１により螺着されている。この端子部材は硬質樹脂等の 絶縁部材からなる一方、金属製の導電リング１は図３（ａ）に示したように外周 部にわずかな段状の肩部１ａを介して一体的に形成された円周状フランジ１ｂを 有する断面形が略Ｚ字形をなすプレス加工品である。 また図４に示したように導電リング１の内周縁の一端には端子部材４の長手方 向に延在するように屈曲された細長形状の舌状端子板１５が一体的に形成されて いる。本実施例ではこの舌状端子板１５には図示したように３個の結線用端子孔 ２３と、この舌状端子板１５を所定の長さに切断可能な切欠１６が所定の間隔を あけて形成されている。この結線用端子孔２３と切欠１６の数、位置は設計上任 意に設けることができる。Further, a substantially tubular terminal member 4 in which a plurality of conductive rings 1 are laminated in the axial direction is screwed to an end of the rotary shaft 12 by a screw portion 11. This terminal member is made of an insulating member such as hard resin, while the metal conductive ring 1 is integrally formed on the outer peripheral portion with a slight stepped shoulder 1a as shown in FIG. 3 (a). It is a pressed product having a substantially Z-shaped cross section with a circumferential flange 1b. As shown in FIG. 4, one end of the inner peripheral edge of the conductive ring 1 is integrally formed with an elongated tongue-shaped terminal plate 15 that is bent so as to extend in the longitudinal direction of the terminal member 4. . In this embodiment, the tongue-shaped terminal plate 15 is provided with three connection terminal holes 23 as shown in the drawing and a notch 16 capable of cutting the tongue-shaped terminal plate 15 into a predetermined length at predetermined intervals. Has been formed. The number and positions of the connection terminal holes 23 and the notches 16 can be arbitrarily set in design.
【００１３】 一方、端子部材４のネジ部１１と長手方向の反対側の端部にはつば状のフラン ジ１４が形成されており、図１に示したようにこのフランジ１４に端部の導電リ ング１が当接するようにして導電リング１と樹脂製の絶縁スペーサ３とが交互に 端子部材４の胴部５に外嵌されている。本実施例ではともに６枚の導電リング１ と絶縁スペーサ３とが配置されており、図３（ａ）に示したように端部の絶縁ス ペーサが胴部５端部位置とほぼ一致し、回転軸１２の空洞内にネジ部１１をねじ 込んだ際に、各導電リング１と絶縁スペーサ３とは回転軸１２の端面とフランジ １４とに挟まれるように密着する。On the other hand, a flange-shaped flange 14 is formed at the end portion of the terminal member 4 opposite to the threaded portion 11 in the longitudinal direction, and as shown in FIG. The conductive ring 1 and the insulating spacer 3 made of resin are alternately fitted onto the body portion 5 of the terminal member 4 so that the ring 1 contacts. In this embodiment, both of the six conductive rings 1 and the insulating spacers 3 are arranged. As shown in FIG. 3 (a), the insulating spacers at the ends substantially coincide with the positions of the ends of the body 5, When the threaded portion 11 is screwed into the cavity of the rotating shaft 12, each conductive ring 1 and the insulating spacer 3 are in close contact with each other so as to be sandwiched between the end face of the rotating shaft 12 and the flange 14.
【００１４】 これにより各導電リング１は絶縁スペーサ３により確実に絶縁されるとともに 、端子部材の胴部５の表面には略コ字形の複数の円周状溝が形成される。この円 周状溝はスリップリングの導電トラックＴを構成し、図２に示したように矢印Ａ 方向に付勢された導電ブラシ２が円周状溝の導電トラックＴの一部に当接し、導 電リング１と導電トラックＴとの電気的接続が行われる。 ここで、舌状端子板１５と電気通信用ケーブル９との接続方法について説明す る。 電気通信用ケーブル９は図２に示したように端子部材４の中心部に長手方向に 形成された貫通孔１３に望遠鏡側から挿通され、その先端部８は図１〜図４に示 したように端子部材４の端面から突出した舌状端子板１５の結線用端子孔２３に 半田付け７されている。As a result, each conductive ring 1 is reliably insulated by the insulating spacer 3, and a plurality of substantially U-shaped circumferential grooves are formed on the surface of the body portion 5 of the terminal member. The circumferential groove constitutes a conductive track T of the slip ring, and the conductive brush 2 biased in the direction of arrow A contacts a part of the conductive track T of the circumferential groove as shown in FIG. Electrical connection between the conductive ring 1 and the conductive track T is established. Here, a method of connecting the tongue-shaped terminal plate 15 and the telecommunication cable 9 will be described. As shown in FIG. 2, the cable 9 for telecommunications is inserted from the telescope side into a through hole 13 formed in the center of the terminal member 4 in the longitudinal direction, and the tip 8 thereof is as shown in FIGS. It is soldered 7 to the connection terminal hole 23 of the tongue-shaped terminal plate 15 protruding from the end face of the terminal member 4.
【００１５】 本実施例では６本の導電リング１が設けられており、各導電リング１から延設 された舌状端子板１５を収容するために６個の端子板収容孔６が端子部材４の中 央の貫通孔１３の周囲に配設され、舌状端子板１５は各端子板収容孔６の各孔内 に収容される。 したがって、貫通孔１３から延出した電気通信用ケーブル９の先端８は周囲の ６箇所に同様に延出した各舌状端子板１５の結線用端子孔２３に半田付け７され る。このとき舌状端子板１５が形成されている導電リング１はプレス加工品であ り、各舌状端子板１５の長さは一定に加工されている。このため導電リング１を 絶縁スペーサ３を介して端子部材４の軸線方向に所定のピッチをあけてずらすよ うに積層する。これにより舌状端子板１５の端子部材４フランジ端面からの突出 長Ｌが螺旋状にずれてくる。そこで前述の切欠１６を利用して適当な突出長Ｌが 得られるように各舌状端子板１５をほぼ一定長さに揃えて切断する。In this embodiment, six conductive rings 1 are provided, and six terminal plate accommodating holes 6 are provided for accommodating the tongue-shaped terminal plates 15 extending from each conductive ring 1. The tongue-shaped terminal plate 15 is arranged around the central through hole 13 and is accommodated in each of the terminal plate accommodation holes 6. Therefore, the tip 8 of the telecommunication cable 9 extending from the through hole 13 is soldered 7 to the connection terminal holes 23 of the respective tongue-shaped terminal plates 15 that also extend to the six surrounding locations. At this time, the conductive ring 1 on which the tongue-shaped terminal plate 15 is formed is a pressed product, and the length of each tongue-shaped terminal plate 15 is processed to be constant. For this reason, the conductive rings 1 are laminated via the insulating spacer 3 so as to be displaced in the axial direction of the terminal member 4 with a predetermined pitch. As a result, the protruding length L of the tongue-shaped terminal plate 15 from the end surface of the flange of the terminal member 4 is shifted in a spiral manner. Therefore, each of the tongue-shaped terminal plates 15 is cut into a substantially constant length by using the above-mentioned notch 16 so that an appropriate protruding length L can be obtained.
【００１６】 これにより端子部材４の端面部分からの電気通信用ケーブル９の接続部分の突 出長Ｌを小さくでき、測量機等の内部の省スペース化が図れる。また貫通孔を通 じて導かれた電気通信用ケーブル９のリード線の先端８は各舌状端子板１５と結 線用端子孔を利用して結線される。このとき各舌状端子板１５は図２及び図３（ ｂ）に示したように端子板収容孔６内に独立して収容されているので、高い絶縁 性が保持される。 一方、固定側の接触子である各導電ブラシ２は前述のようにバネ性により対応 する各導電トラックＴに所定の接触圧で当接し、対応する電気通信用ケーブル９ と接続ケーブル３４とが電気的に接続される。As a result, the protrusion length L of the connecting portion of the electric communication cable 9 from the end surface portion of the terminal member 4 can be reduced, and the space inside the surveying instrument or the like can be saved. Further, the tip 8 of the lead wire of the electric communication cable 9 guided through the through hole is connected to each tongue-shaped terminal plate 15 using the connecting terminal hole. At this time, since each tongue-shaped terminal plate 15 is accommodated independently in the terminal plate accommodating hole 6 as shown in FIGS. 2 and 3B, high insulation is maintained. On the other hand, as described above, the conductive brushes 2 serving as fixed-side contacts are brought into contact with the corresponding conductive tracks T by a predetermined contact pressure due to the spring property, and the corresponding telecommunication cables 9 and the connection cables 34 are electrically connected. Connected.
【００１７】 なお、本実施例では６本の導電リング１と絶縁スペーサ３とが端子部材４の胴 部５に外嵌されているが、この胴部５の長さをあらかじめ最大トラック数の導電 リング数を装着できる長さに設定しておき、必要に応じて厚さ調整用のスペーサ を装着することで簡単に電気通信用極数を変更することもできる。 次に、前述の実施例の変形例として異形の導電リングを装着し、スリップリン グとしての性能を高めたものについて説明する。In this embodiment, the six conductive rings 1 and the insulating spacers 3 are externally fitted to the body 5 of the terminal member 4. The length of the body 5 is set to the maximum number of conductive tracks in advance. It is possible to easily change the number of poles for telecommunications by setting the number of rings so that it can be installed and installing spacers for adjusting the thickness if necessary. Next, as a modified example of the above-described embodiment, a deformed conductive ring is attached to improve the slip ring performance.
【００１８】 図５（ａ）は絶縁スペーサ３と導電リング１との間に導電リング１と同内外径 の金属製の平座金３３を装着した変形例を示したものである。このように金属製 の平座金３３を取り付けることにより導電トラックＴに相当する円周状溝全体を 金属部分で覆うことができ、測量機に衝撃が加えられた場合等に前述の導電ブラ シが側方にずれて絶縁スペーサ３に接触してトラックの導電リング１部分との接 触不良が生じるのを防止することができる。FIG. 5A shows a modification in which a flat metal washer 33 having the same inner and outer diameters as the conductive ring 1 is mounted between the insulating spacer 3 and the conductive ring 1. By mounting the flat washer 33 made of metal in this way, the entire circumferential groove corresponding to the conductive track T can be covered with the metal portion, and the conductive brush described above can be removed when a shock is applied to the surveying instrument. It is possible to prevent the track from being displaced laterally and coming into contact with the insulating spacer 3 to cause defective contact with the conductive ring 1 portion of the track.
【００１９】 また、図５（ｂ）は導電リング１と同形のリングをリング同士が対向するよう に配置した変形例を示したものである。この変形例の場合には２枚の対向して配 置された導電リング１Ａ、１Ｂにより略Ｕ字形断面の円周溝が形成され、この円 周状溝の一部に導電ブラシが確実に接触して電気的接続が可能になる。この変形 例は特に振動や衝撃を受け易い場所に設置される測量機においても確実な戦記的 接続を得ることができるという効果がある。 なお、前述の導電リング１と絶縁スペーサ３とは別々に製造しておき、組立時 に各部品を組み合わせて端子部材４を構成するようにしても良いし、あらかじめ １組の導電リング１と絶縁スペーサ３とを一体成形しておき、それらを端子部材 ４の胴部５に複数組積層するようにして所定数のトラックを構成するようにして も良い。FIG. 5B shows a modified example in which rings having the same shape as the conductive ring 1 are arranged so that the rings face each other. In the case of this modified example, a circumferential groove having a substantially U-shaped cross section is formed by the two conductive rings 1A and 1B arranged so as to face each other, and the conductive brush surely contacts a part of this circumferential groove. Then, electrical connection becomes possible. This modified example has an effect that a reliable war memorial connection can be obtained even in a surveying instrument installed in a place susceptible to vibration or impact. The conductive ring 1 and the insulating spacer 3 described above may be manufactured separately, and each component may be combined to form the terminal member 4 at the time of assembly. A predetermined number of tracks may be formed by integrally molding the spacer 3 and stacking a plurality of sets on the body portion 5 of the terminal member 4.
【００２０】 以上の説明は測量機の望遠鏡部の回転軸（水平軸）を例に行ったが、測量機本 体を支持する鉛直軸と、測量機本体との電気的接続に対して本考案によるスリッ プリングの構成を適用してもよいことは明らかであり、その他回転軸を備えた箇 所の電気的接続を要する部分に本考案によるスリップリングを適用することも可 能である。The above description has been made by taking the rotary axis (horizontal axis) of the telescope part of the surveying instrument as an example. It is clear that the slip ring structure according to the present invention may be applied, and it is also possible to apply the slip ring according to the present invention to other portions where electrical connection is required at a portion equipped with a rotary shaft.
【００２１】[0021]
以上の説明から明らかなように、本考案によれば、電気通信用ケーブルと導電 リングとの電気的接続を容易かつ確実にできるとともに、導電リングと絶縁スペ ーサをそれぞれ同形の部品で構成することで安価であり、電気通信用極数を変更 する際にも容易に所定の極数の構造を実現できるという効果を奏する。 As is apparent from the above description, according to the present invention, the electrical connection between the telecommunication cable and the conductive ring can be easily and securely made, and the conductive ring and the insulating spacer are formed of the same parts. Therefore, it is inexpensive, and there is an effect that a structure having a predetermined number of poles can be easily realized even when the number of poles for telecommunication is changed.
