Description

計器本体Instrument body
　本発明は、指針を回転駆動する計器本体に関し、特に、半田を使用せずに回路基板に電気的な接続が可能な計器本体に関する。 The present invention relates to an instrument body that rotationally drives a pointer, and more particularly to an instrument body that can be electrically connected to a circuit board without using solder.
　従来の計器本体は、例えば、特許文献１に開示されるものがある。従来の計器本体は、計器本体に圧入式コネクタ端子を備えている。このコネクタ端子は、一般的に、一つの貫通孔と互いに離れた二つの外側部分とから形成される変形可能な接続部からなる。回路基板として考えることが可能な支持体の貫通孔にコネクタ端子を挿入する時に、変形可能な接続部は、支持体に加わる圧力によって変形し、貫通孔の内部と変形可能な接続部の間の相互作用と摩擦力によって、コネクタ端子の電気的接続と機械的な支持を生ずるものであった。 A conventional instrument body is disclosed in Patent Document 1, for example. A conventional instrument body includes a press-fit connector terminal in the instrument body. This connector terminal generally consists of a deformable connection formed by one through hole and two outer parts spaced apart from each other. When the connector terminal is inserted into the through hole of the support body that can be considered as a circuit board, the deformable connection portion is deformed by the pressure applied to the support body, and between the inside of the through hole and the deformable connection portion. The interaction and frictional force resulted in electrical connection and mechanical support of the connector terminals.
特表２００８－５４１４４３号公報（図２参照）JP 2008-541443 (see FIG. 2)
　従来の計器本体において、変形可能な接続部を備えたコネクタ端子を計器本体に固定する構造としては、前記コネクタ端子を前記接続部側から計器本体に設けた固定用貫通孔に挿入する場合、径が大きな前記接続部側が貫通することによって、前記固定用貫通孔の内径が、前記コネクタ端子の取付部の径より大きくなり、前記コネクタ端子を圧入によって前記固定用貫通孔に固定しにくくなるという問題点があった。 In a conventional instrument body, as a structure for fixing a connector terminal having a deformable connection part to the instrument body, the diameter of the connector terminal is inserted from the connection part side into a fixing through hole provided in the instrument body. When the large connecting portion side penetrates, the inner diameter of the fixing through-hole becomes larger than the diameter of the mounting portion of the connector terminal, and it becomes difficult to fix the connector terminal to the fixing through-hole by press-fitting. There was a point.
　また、他の固定構造としては、前記コネクタ端子を前記接続部側とは反対側から計器本体に設けた固定用貫通孔に挿入する場合、前記コネクタ端子の取付部の径に対して、前記固定用貫通孔の内径が大きくなることはなく、前記コネクタ端子を圧入によって前記固定用貫通孔に固定しにくくなるという問題点は解決する。しかし、前記コネクタ端子に固定されるコイルの損傷を防止するために、前記コイルを前記コネクタに絡げた後に、前記コネクタの圧入方向とは、反対の方向に前記コネクタを戻し、前記コイルに弛みを持たせる作業が必要となる。この作業を行うために、前記計器本体を扱う設備が大型化する。また、一度圧入された前記コネクタ端子を再度移動させることによって、前記固定用貫通孔の圧入状態が変化し、前記固定用貫通孔に固定しにくくなるという問題点があった。 Further, as another fixing structure, when the connector terminal is inserted into the fixing through hole provided in the instrument body from the side opposite to the connection portion side, the fixing is performed with respect to the diameter of the mounting portion of the connector terminal. The inner diameter of the through hole for use does not increase, and the problem that it becomes difficult to fix the connector terminal to the through hole for fixing by press fitting is solved. However, in order to prevent damage to the coil fixed to the connector terminal, after the coil is entangled with the connector, the connector is returned in a direction opposite to the press-fitting direction of the connector, and the coil is slackened. Work to have it is necessary. In order to perform this work, the equipment for handling the instrument main body is enlarged. Further, when the connector terminal once press-fitted is moved again, the press-fitted state of the fixing through hole is changed, which makes it difficult to fix the fixing terminal to the fixing through hole.
　また、前記接続部の外径を前記コネクタ端子の取付部よりも小さくした形状も考えられるが、前記コネクタ端子の取付部を前記接続部部分より大きくするには、前記コネクタ端子を形成する母材の前記取付部に対応する部分の径を予め大きく形成する必要があり、部品のコストの上昇を招くという問題点があった。 A shape in which the outer diameter of the connection portion is smaller than the attachment portion of the connector terminal is also conceivable. In order to make the attachment portion of the connector terminal larger than the connection portion portion, a base material for forming the connector terminal is used. The diameter of the portion corresponding to the mounting portion must be formed in advance to increase the cost of the parts.
　そこで本発明は、前記問題点を解消し、半田を使用せずに電気的な接続が可能で、かつ、計器本体へ確実に固定可能なコネクタ端子を有する計器本体を提供することを目的とするものである。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems and to provide an instrument body having a connector terminal that can be electrically connected without using solder and can be securely fixed to the instrument body.

A deformable connection part and an attachment part inserted into a fixing through hole provided in the holding part are provided in the connector terminal, and the connection part protrudes in a direction perpendicular to the longitudinal direction of the connector terminal. Provided with a connecting protrusion, the mounting portion including a mounting protrusion protruding in a direction perpendicular to the longitudinal direction of the connector terminal, and the mounting protrusion protruding in a direction perpendicular to the longitudinal direction of the connector terminal The direction is different from the direction in which the connection protrusion protrudes, and the inner diameter of the fixing through-hole is larger than the connection protrusion and smaller than the attachment protrusion.
　また、前記接続突出部と前記取付突出部の突出方向は、直角である。 Further, the protruding direction of the connection protrusion and the mounting protrusion is a right angle.

In the space inside the housing 8, the magnet rotor 3, the branch transmission gear portion 5, and the driven transmission gear portion 6 are accommodated. A support shaft 4 is fixed to the housing 8, and a pointer shaft 7 is rotatably supported.
　ハウジング８には、マグネットロータ３のラジアル方向外周に、コイル２が巻かれている巻枠部１２が形成されている。 In the housing 8, a winding frame portion 12 around which the coil 2 is wound is formed on the outer periphery in the radial direction of the magnet rotor 3.
　また、ハウジング８には、巻枠部１２よりマグネットロータ３のラジアル方向外周に、コネクタ端子９を保持する保持部１３が形成されている。 In the housing 8, a holding portion 13 that holds the connector terminal 9 is formed on the outer periphery in the radial direction of the magnet rotor 3 from the winding frame portion 12.
　ハウジング８には、回路基板１１に設けた図示しない孔に係止する係止爪１４を備えた弾性片１５が、設けられている。なお、１６は、回路基板１１に計器本体１を固定する位置を定める位置決めピンである。 The housing 8 is provided with an elastic piece 15 provided with a locking claw 14 for locking in a hole (not shown) provided in the circuit board 11. Reference numeral 16 denotes a positioning pin that determines the position at which the instrument body 1 is fixed to the circuit board 11.
　コイル２は、銅などの導電性を有する金属線からなり、合成樹脂からなるハウジング８の巻枠部１２に巻き付けられている。コイル２は、２つ設けられており、それぞれハウジング８に設けたコネクタ端子９を介して、制御手段に接続されている。そして、２つのコイル２には、図示しない制御手段から出力される駆動波形が、それぞれ入力されることによって、マグネットロータ３に回転磁界が発生し、マグネットロータ３に回転力を与えるものである。 The coil 2 is made of a metal wire having conductivity such as copper, and is wound around the winding frame portion 12 of the housing 8 made of synthetic resin. Two coils 2 are provided, and are connected to the control means via connector terminals 9 provided on the housing 8 respectively. The two coils 2 are respectively input with drive waveforms output from a control means (not shown), so that a rotating magnetic field is generated in the magnet rotor 3 and a rotational force is applied to the magnet rotor 3.
　コネクタ端子９は、四角柱形状であり、金属、例えば、リン青銅からなり、その表面に、亜鉛メッキが施されている。コネクタ端子９は、接続部９１と取付部９２とを備えている。 The connector terminal 9 has a quadrangular prism shape and is made of metal, for example, phosphor bronze, and the surface thereof is galvanized. The connector terminal 9 includes a connection portion 91 and an attachment portion 92.
　接続部９１は、一つの貫通孔９３と互いに離れた二つの接続突出部９４とから形成されている。貫通孔９３は、楕円形状をしており、接続突出部９４は、コネクタ端子９の長手方向に対して垂直方向に突出している。接続突出部９４の突出する方向は、図５で示すように、コネクタ端子９の中心線Ｇに対して垂直方向に延びる補助線Ｓ方向に沿って、中心線Ｇから放射する方向である。接続部９１の接続突出部９４は、貫通孔９３方向へ変形可能である。接続部９１の外径は、回路基板１１に設けた貫通孔１７より大きいため、接続部９１を貫通孔１７に挿入すると、接続部９１は変形する（図８参照）。 The connecting portion 91 is formed by one through hole 93 and two connecting protrusions 94 separated from each other. The through hole 93 has an elliptical shape, and the connection protrusion 94 protrudes in a direction perpendicular to the longitudinal direction of the connector terminal 9. As shown in FIG. 5, the protruding direction of the connection protruding portion 94 is a direction radiating from the center line G along the auxiliary line S direction extending in a direction perpendicular to the center line G of the connector terminal 9. The connection protrusion 94 of the connection portion 91 can be deformed in the direction of the through hole 93. Since the outer diameter of the connecting portion 91 is larger than the through hole 17 provided in the circuit board 11, when the connecting portion 91 is inserted into the through hole 17, the connecting portion 91 is deformed (see FIG. 8).
　取付部９２は、ハウジング８の保持部１３に保持される部分である。取付部９２は、コネクタ端子９の長手方向に対して垂直方向に突出した取付突出部９５を備えている。 The mounting portion 92 is a portion that is held by the holding portion 13 of the housing 8. The mounting portion 92 includes a mounting protrusion 95 that protrudes in a direction perpendicular to the longitudinal direction of the connector terminal 9.
　取付突出部９５のコネクタ端子９の長手方向に対して垂直方向の断面形状は、図６のコネクタ端子９の中心線Ｇに対して垂直方向に延びる補助線Ｓ方向に沿った接続突出部９４の突出方向に対して、４５度方向に４方向に突出した＋字形状である。この取付突出部９５は、プレス加工によって形成されるものである。取付突出部９５の形状によって、取付突出部９５は、接続突出部９４と同方向に突出するとともに、接続突出部９４の突出方向（図６中の直線Ｓ方向）に対して、直角方向に突出している。従って、取付突出部９５は、コネクタ端子９の長手方向に対して垂直方向に突出しており、この突出した方向が、接続突出部９４が突出した方向と異なっている。 The cross-sectional shape of the mounting projection 95 in the direction perpendicular to the longitudinal direction of the connector terminal 9 is such that the connection projection 94 extends along the auxiliary line S extending in the direction perpendicular to the center line G of the connector terminal 9 in FIG. It is a + -shape projecting in four directions in a 45 degree direction with respect to the projecting direction. The attachment protrusion 95 is formed by press working. Depending on the shape of the mounting projection 95, the mounting projection 95 projects in the same direction as the connection projection 94, and projects in a direction perpendicular to the projection direction of the connection projection 94 (the straight line S direction in FIG. 6). ing. Therefore, the mounting protrusion 95 protrudes in a direction perpendicular to the longitudinal direction of the connector terminal 9, and this protruding direction is different from the direction in which the connection protrusion 94 protrudes.
　取付部９２は、ハウジング８の保持部１３に設けた固定用貫通孔１９に挿入される。この固定用貫通孔１９の形状は、コネクタ端子９の長手方向に垂直な方向の断面形状は、矩形形状である。固定用貫通孔１９の内径は、長辺方向が、接続突出部９４と取付突出部９５より大きい第１内径部１９ａであり、短辺方向が、取付突出部９５より小さく、接続突出部９４より大きい第２内径部１９ｂである。このような構成によって、コネクタ端子９が、接続部９１側から固定用貫通孔１９を貫通する場合に、第１内径部１９ａは、接続突出部９４より大きいため、接続突出部９４が固定用貫通孔１９内に接触して削ることはなく、ひいては、固定用貫通孔１９を拡げることはない。また、取付突出部９５が固定用貫通孔１９に挿入される場合は、取付突出部９５は、固定用貫通孔１９の第１内径部１９ａより小さいが、第２内径部１９ｂより大きいため、取付突出部９５が固定用貫通孔１９内に接触し、圧入状態となり、取付突出部９５が固定用貫通孔１９内に保持される。 The mounting portion 92 is inserted into the fixing through hole 19 provided in the holding portion 13 of the housing 8. The fixing through-hole 19 has a rectangular cross-sectional shape in the direction perpendicular to the longitudinal direction of the connector terminal 9. The inner diameter of the fixing through-hole 19 is a first inner diameter portion 19a whose long side direction is larger than the connection protrusion 94 and the attachment protrusion 95, and whose short side direction is smaller than that of the attachment protrusion 95, than the connection protrusion 94. A large second inner diameter portion 19b. With such a configuration, when the connector terminal 9 passes through the fixing through hole 19 from the connecting portion 91 side, the first inner diameter portion 19a is larger than the connecting protruding portion 94, so that the connecting protruding portion 94 is fixed through. The hole 19 is not cut in contact with the hole 19, and as a result, the fixing through-hole 19 is not expanded. When the mounting protrusion 95 is inserted into the fixing through hole 19, the mounting protrusion 95 is smaller than the first inner diameter portion 19a of the fixing through hole 19, but larger than the second inner diameter portion 19b. The projecting portion 95 comes into contact with the fixing through hole 19 and press-fit, and the mounting projecting portion 95 is held in the fixing through hole 19.
　コネクタ端子９は、コイル２と回路基板１１とに電気的に接続されている。コイル２は、コネクタ端子９の接続突出部９４を設けた側とは反対側に巻き付けられた後、半田によってコネクタ端子９に固定されている。また、回路基板１１に設けた貫通孔１７には、図７に示すように、貫通孔１７の内部と貫通孔１７の開口部とに、銅などの導電性の金属からなる配線パターン１８が設けられており、コネクタ端子９の接続突出部９４が、配線パターン１８に接触することによって、電気的に接続されている。 The connector terminal 9 is electrically connected to the coil 2 and the circuit board 11. The coil 2 is wound around the side of the connector terminal 9 opposite to the side on which the connection protrusion 94 is provided, and then fixed to the connector terminal 9 with solder. Further, as shown in FIG. 7, a wiring pattern 18 made of a conductive metal such as copper is provided in the through hole 17 provided in the circuit board 11 in the inside of the through hole 17 and the opening of the through hole 17. The connection protrusion 94 of the connector terminal 9 is electrically connected by contacting the wiring pattern 18.
　シールドケース１０は、パーマロイなどの磁性材料からなり、ハウジング８の所定領域を覆うカップ形状である。 The shield case 10 is made of a magnetic material such as permalloy and has a cup shape that covers a predetermined area of the housing 8.
　回路基板１１は、ガラスエポキシ基板などの硬質の絶縁基材に配線パターン１８を設けたものである。 The circuit board 11 is obtained by providing a wiring pattern 18 on a hard insulating base material such as a glass epoxy board.
　次に、コネクタ端子９を計器本体１に固定する工程を図１１を用いて説明する。始めに、図１１（ａ）で示すように、コネクタ端子９が、接続部９１側から固定用貫通孔１９に挿入される。図１１（ｂ）で示すように、取付部９２の一部が、固定用貫通孔１９に圧入された状態とする。 Next, the process of fixing the connector terminal 9 to the instrument body 1 will be described with reference to FIG. First, as shown in FIG. 11A, the connector terminal 9 is inserted into the fixing through hole 19 from the connection portion 91 side. As shown in FIG. 11B, a part of the attachment portion 92 is press-fitted into the fixing through hole 19.
　図１１（ｂ）は、図１１（ａ）の矢印Ｆ方向から見た断面図である。取付部９２の一部が、固定用貫通孔１９に圧入された状態で、ハウジング８に巻き付けられたコイル２の端部をコネクタ端子９に巻き付けた後、半田付けし、コイル２をコネクタ端子９に固定する。 FIG. 11 (b) is a cross-sectional view seen from the direction of arrow F in FIG. 11 (a). In a state in which a part of the attachment portion 92 is press-fitted into the fixing through hole 19, the end portion of the coil 2 wound around the housing 8 is wound around the connector terminal 9 and then soldered, and the coil 2 is connected to the connector terminal 9. Secure to.
　コイル２を固定したコネクタ端子９を、さらに、コネクタ端子９を所定の位置まで挿入する（図１１（ｃ）、（ｄ）参照）。図１１（ｄ）は、図１１（ａ）と同じ方向から見た断面図である。このように、コイル２をコネクタ端子９に固定後、さらにコネクタ端子９を挿入することで、コイル２がたわみ、コイル２の損傷を防止することができる。 The connector terminal 9 to which the coil 2 is fixed is inserted into the connector terminal 9 to a predetermined position (see FIGS. 11C and 11D). FIG.11 (d) is sectional drawing seen from the same direction as Fig.11 (a). As described above, after the coil 2 is fixed to the connector terminal 9, the connector terminal 9 is further inserted, whereby the coil 2 is bent and damage to the coil 2 can be prevented.
　以上のように構成された計器本体１は、各コイル２を励磁することにより、各々磁界ベクトルが働き、これら各磁界ベクトルの強さに応じて４極着磁されたマグネットロータ３が回転し、その回転が、分岐伝達ギヤ部５、従動伝達ギヤ部６を通じて指針軸７に伝達され、指針軸７に固定された前記指針が角度運動するものである。この際、分岐伝達ギヤ部５と従動伝達ギヤ部６は、分岐伝達ギヤ部５に対し従動伝達ギヤ部６が、低速（減速）回転するように、それぞれのギヤ比が設定されており、この減速作動により、入力信号に対して指示誤差の少ない前記指針の角度運動が可能となる。 In the instrument body 1 configured as described above, by exciting each coil 2, each magnetic field vector works, and the magnet rotor 3 magnetized with four poles according to the strength of each magnetic field vector rotates, The rotation is transmitted to the pointer shaft 7 through the branch transmission gear portion 5 and the driven transmission gear portion 6, and the pointer fixed to the pointer shaft 7 is angularly moved. At this time, the gear ratios of the branch transmission gear unit 5 and the driven transmission gear unit 6 are set so that the driven transmission gear unit 6 rotates at a low speed (deceleration) with respect to the branch transmission gear unit 5. By the deceleration operation, it is possible to perform the angular movement of the pointer with little instruction error with respect to the input signal.
　第１実施形態では、固定用貫通孔１９の形状は、矩形形状であったが、前記実施形態に限定されるものではなく、例えば、図１２で示す第２実施形態では、固定用貫通孔２０のコネクタ端子９の挿入方向に対して垂直方向の形状を、楕円形状としたものである。 In the first embodiment, the shape of the fixing through hole 19 is a rectangular shape, but is not limited to the above embodiment. For example, in the second embodiment shown in FIG. The shape perpendicular to the insertion direction of the connector terminal 9 is an elliptical shape.
　固定用貫通孔２０の内径は、接続突出部９４に対して、接続突出部９４の４つの角部が、全て固定用貫通孔２０の内径に接触することはなく、取付突出部９５に対して、取付突出部９５の４つの角部が、全て固定用貫通孔２０の内径に接触するものである。このような構成によって、コネクタ端子９が、接続部９１側から固定用貫通孔２０を貫通する場合に、固定用貫通孔２０は、接続突出部９４より大きいため、接続突出部９４が固定用貫通孔２０内に接触して削ることはなく、ひいては、固定用貫通孔２０を拡げることはない。また、取付突出部９５が固定用貫通孔２０に挿入される場合は、取付突出部９５は、固定用貫通孔２０より大きいため、取付突出部９５が固定用貫通孔２０内に接触し、圧入状態となり、取付突出部９５が固定用貫通孔２０内に保持される。 The inner diameter of the fixing through-hole 20 is such that the four corners of the connection protrusion 94 do not contact the inner diameter of the fixing through-hole 20 with respect to the connection protrusion 94, and The four corners of the mounting protrusion 95 are all in contact with the inner diameter of the fixing through hole 20. With such a configuration, when the connector terminal 9 passes through the fixing through hole 20 from the connecting portion 91 side, the fixing through hole 20 is larger than the connecting protruding portion 94, so that the connecting protruding portion 94 is fixed through. There is no need to scrape in contact with the inside of the hole 20, and as a result, the fixing through-hole 20 is not expanded. Further, when the mounting protrusion 95 is inserted into the fixing through-hole 20, the mounting protrusion 95 is larger than the fixing through-hole 20, so that the mounting protrusion 95 comes into contact with the fixing through-hole 20 and press-fits. The mounting protrusion 95 is held in the fixing through hole 20.
