以下、本発明の実施形態について図1〜図9を参照して説明する。なお、以下の説明における前後左右等の向きは、特に記載が無ければ以下に説明する車両における向きと同一とする。   Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 9. It should be noted that the directions such as front, rear, left and right in the following description are the same as the directions in the vehicle described below unless otherwise specified.

図1に示すように、鞍乗り型車両としての自動二輪車の下後部には、リヤブレーキ作動装置100が設けられている。
リヤブレーキ作動装置100は、運転者によるブレーキペダル1の踏み込みによって作動するリヤブレーキ装置(図示略)と、運転者によるブレーキペダル1の踏み込みを検出するブレーキ作動検出装置101と、を具備している。図中矢印FRは車両前方、矢印UPは車両上方をそれぞれ示す。
As shown in FIG. 1, a rear brake actuating device 100 is provided in the lower rear part of a motorcycle as a saddle-ride type vehicle.
The rear brake actuation device 100 includes a rear brake device (not shown) that operates when the driver depresses the brake pedal 1, and a brake operation detection device 101 that detects the depression of the brake pedal 1 by the driver. . In the figure, an arrow FR indicates the front of the vehicle, and an arrow UP indicates the upper side of the vehicle.

ブレーキペダル1は、例えば車体フレームFに支持された左右方向に沿う支軸2を中心として回転可能に設けられたブレーキアーム3を具備する。ブレーキアーム3は、支軸2の前方側に延びて全体として折曲形状に設けられた第一アーム5と、支軸2の上方側に延びる第二アーム6と、を有している。第一アーム5の前端部にはペダル踏込部7が設けられ、第二アーム6の上端部にはリヤブレーキ装置(図示略)を作動させるための例えばプルロッド等の作動部材8が連結されている。図中符号40は運転者の足を載せる運転者用ステップ、符号41は鞍乗り型車両の駆動源となるパワーユニットをそれぞれ示す。   The brake pedal 1 includes, for example, a brake arm 3 which is rotatably provided around a support shaft 2 which is supported by the vehicle body frame F and extends in the left-right direction. The brake arm 3 has a first arm 5 extending forward of the support shaft 2 and provided in a bent shape as a whole, and a second arm 6 extending above the support shaft 2. A pedal step portion 7 is provided at a front end portion of the first arm 5, and an operation member 8 such as a pull rod for operating a rear brake device (not shown) is connected to an upper end portion of the second arm 6. . In the figure, reference numeral 40 denotes a driver step for placing the driver's foot, and reference numeral 41 denotes a power unit serving as a drive source of the saddle type vehicle.

第一アーム5には、引張コイルバネ4を介して、ブレーキ作動検出装置101のフットブレーキスイッチ10のロッド13が接続されている。
図2〜図4を併せて参照し、フットブレーキスイッチ10は、例えば車体フレームFに固定されたブラケット9にアジャストナット18Aを介して支持されている。フットブレーキスイッチ10は筒状をなし、その長手方向を概ね上下方向(詳細には、上下方向に対してやや後傾した方向、矢印A−B方向)に沿わせて配置されている。
The rod 13 of the foot brake switch 10 of the brake operation detecting device 101 is connected to the first arm 5 via the tension coil spring 4.
With reference to FIGS. 2 to 4 together, the foot brake switch 10 is supported by, for example, the bracket 9 fixed to the vehicle body frame F via the adjust nut 18A. The foot brake switch 10 has a tubular shape and is arranged with its longitudinal direction substantially along the up-down direction (specifically, a direction slightly tilted backward with respect to the up-down direction, arrow A-B direction).

以下、フットブレーキスイッチ10の長手方向をスイッチ軸方向とし、図2〜図4の上下方向(A−B方向)をフットブレーキスイッチ10の上下方向とし、図2、図4の左右方向をフットブレーキスイッチ10の左右方向(スイッチ左右方向)とし、図3の左右方向をフットブレーキスイッチ10の前後方向(スイッチ前後方向)として説明する。   Hereinafter, the longitudinal direction of the foot brake switch 10 will be referred to as a switch axis direction, the vertical direction (AB direction) of FIGS. 2 to 4 will be referred to as the vertical direction of the foot brake switch 10, and the lateral direction of FIGS. 2 and 4 will be the foot brake. The left-right direction of the switch 10 (switch left-right direction) will be described as the left-right direction of FIG. 3 as the front-back direction of the foot brake switch 10 (switch front-back direction).

ペダル踏込部7が踏まれてブレーキペダル1が回動すると、引張コイルバネ4を介してロッド13が下方に引かれ、スイッチ本体部12内のスイッチ回路14が作動する。例えば、スイッチ回路14は、ロッド13が下方に引かれる前は、後述する一対の接続端子15間の通電を遮断し、ロッド13が下方に引かれると、一対の接続端子15間を通電させるというON/OFFスイッチを構成している。   When the pedal depression part 7 is stepped on and the brake pedal 1 is rotated, the rod 13 is pulled downward via the tension coil spring 4, and the switch circuit 14 in the switch body 12 is activated. For example, the switch circuit 14 interrupts energization between a pair of connection terminals 15 described later before the rod 13 is pulled downward, and energizes between the pair of connection terminals 15 when the rod 13 is pulled downward. It constitutes an ON / OFF switch.

フットブレーキスイッチ10は、ペダル踏込部7が踏まれてロッド13が下方に引かれた際に、スイッチ回路14が一対の接続端子15間を通電させてリアブレーキランプ(不図示)を点灯させる。また、ペダル踏込部7が踏まれたとき、第二アーム6が作動部材8を介してリヤブレーキ装置を制動作動させる。リヤブレーキランプの点灯およびリヤブレーキ装置の制動作動は、ブレーキペダル1の踏み込みを解除することで解除される。   In the foot brake switch 10, when the pedal stepping portion 7 is stepped on and the rod 13 is pulled downward, the switch circuit 14 energizes the pair of connection terminals 15 to light a rear brake lamp (not shown). Further, when the pedal stepping portion 7 is stepped on, the second arm 6 brakes the rear brake device via the operating member 8. The lighting of the rear brake lamp and the braking operation of the rear brake device are released by releasing the depression of the brake pedal 1.

次に、フットブレーキスイッチ10について詳細に説明する。
図2〜図5を参照し、フットブレーキスイッチ10は、スイッチ軸方向に延びる筒状をなして内部に中空部11を形成するスイッチ本体部12と、中空部11の下側にスイッチ軸方向でストローク可能に保持されるロッド13と、ロッド13のストロークに応じてON/OFF作動するスイッチ回路14と、スイッチ回路14に接続される一対の接続端子15と、を有している。
Next, the foot brake switch 10 will be described in detail.
2 to 5, the foot brake switch 10 includes a switch main body 12 having a tubular shape extending in the switch axial direction and forming a hollow portion 11 therein, and a switch main body portion 12 below the hollow portion 11 in the switch axial direction. It has a rod 13 that is held so that it can be stroked, a switch circuit 14 that is turned on / off according to the stroke of the rod 13, and a pair of connection terminals 15 that are connected to the switch circuit 14.

フットブレーキスイッチ10は、スイッチ軸方向を上下に起立させた姿勢で配置されている。スイッチ本体部12の上端部17A(一端部)からは、一対の接続端子15がスイッチ軸方向に沿って互いに平行をなして上方に突出している。一対の接続端子15は、それぞれスイッチ左右方向と直交する平板状をなし、互いにスイッチ左右方向(板厚方向)で対向配置されている。図中符号15Aは各接続端子15の突出方向(スイッチ軸方向)に沿う軸線を示す。   The foot brake switch 10 is arranged in a posture in which the switch axis direction is vertically erected. From the upper end portion 17A (one end portion) of the switch main body portion 12, a pair of connection terminals 15 are arranged in parallel with each other along the switch axial direction and project upward. The pair of connection terminals 15 each have a flat plate shape orthogonal to the switch left-right direction, and are arranged to face each other in the switch left-right direction (plate thickness direction). Reference numeral 15A in the drawing indicates an axis line along the protruding direction (switch axis direction) of each connection terminal 15.

スイッチ本体部12は、一対の接続端子15の周囲を囲う角筒状のカバー部材16と、カバー部材16の下方に一体に設けられた円筒状のスリーブ18と、カバー部材16およびスリーブ18に跨って嵌入されて一対の接続端子15の基端側を支持する端子支持部材17と、を有しており、全体が絶縁部材により形成されている。スリーブ18の外面には、アジャストナット18Aを螺合させるネジ山が形成されている。カバー部材16は、スイッチ軸線と平行な前後左右の四面を形成している。   The switch body 12 includes a cover member 16 in the shape of a rectangular tube that surrounds the pair of connection terminals 15, a cylindrical sleeve 18 that is integrally provided below the cover member 16, and extends over the cover member 16 and the sleeve 18. And a terminal support member 17 that supports the base end side of the pair of connection terminals 15 by being inserted thereinto, and is entirely formed of an insulating member. The outer surface of the sleeve 18 is formed with threads for screwing the adjustment nut 18A. The cover member 16 forms four front, rear, left and right surfaces parallel to the switch axis.

ロッド13は、スリーブ18の下端部との間に設けられた圧縮コイルバネ19によって上方に付勢されている。ロッド13は、下端部をスイッチ本体部12の下方に突出させ、この下端部に引張コイルバネ4の上端部が係止されている。ロッド13の上端部は、スイッチ回路14に対してストローク位置を変更可能に係合している。   The rod 13 is biased upward by a compression coil spring 19 provided between the rod 13 and the lower end of the sleeve 18. The lower end of the rod 13 projects below the switch body 12, and the upper end of the tension coil spring 4 is locked to the lower end. The upper end of the rod 13 is engaged with the switch circuit 14 so that the stroke position can be changed.

スイッチ回路14は、ロッド13のストロークによるON/OFFに応じて、一対の接続端子15間の通電状態を切り替える。すなわち、スイッチ回路14がONで一対の接続端子15間に通電がなされたとき、リヤブレーキランプが点灯し、スイッチ回路14がOFFで一対の接続端子15間の通電が遮断されたとき、リヤブレーキランプが消灯する。   The switch circuit 14 switches the energization state between the pair of connection terminals 15 according to ON / OFF depending on the stroke of the rod 13. That is, when the switch circuit 14 is ON and the pair of connection terminals 15 is energized, the rear brake lamp is lit, and when the switch circuit 14 is OFF and the pair of connection terminals 15 is not energized, the rear brake lamp is turned on. The lamp goes off.

フットブレーキスイッチ10は、カバー部材16および一対の接続端子15を含んで雄側接続コネクタ10Aを構成し、雌側接続コネクタ10Bを接続可能としている。
図8を併せて参照し、雌側接続コネクタ10Bは、絶縁材料で形成された被接続側本体部20と、被接続側本体部20内に配置されて一対の接続端子15の各々に接続される一対の雌端子(外部端子)21と、被接続側本体部20内で一対の雌端子21を支持する絶縁部材からなるプラグ支持部材22と、を備えている。一対の雌端子21には、車体側に取り回される導電ハーネス23が接続されている。
The foot brake switch 10 includes a cover member 16 and a pair of connection terminals 15 to form a male side connector 10A, and a female side connector 10B can be connected thereto.
Referring also to FIG. 8, the female-side connector 10B is connected to the connected-side body portion 20 formed of an insulating material and the connected-side body portion 20 and is connected to each of the pair of connection terminals 15. A pair of female terminals (external terminals) 21 and a plug support member 22 made of an insulating member for supporting the pair of female terminals 21 in the connected main body portion 20. The pair of female terminals 21 is connected to a conductive harness 23 arranged on the vehicle body side.

図3を参照し、雄側接続コネクタ10Aのカバー部材16には、雌側接続コネクタ10Bの被接続側本体部20に係合する係合部材24が設けられている。係合部材24は、スイッチ軸方向に延びる弾性片の先端部に係止爪を有し、雌側接続コネクタ10Bの被接続側本体部20の上端部に設けられた係止孔形成部25に係合可能である。これら係合部材24および係止孔形成部25の係合により、雄側接続コネクタ10Aと雌側接続コネクタ10Bとの連結解除が制限される。これら両コネクタ10A,10Bの連結により、各接続端子15と各雌端子21との導通がなされ、両コネクタ10A,10Bの分離により、各接続端子15と各雌端子21との導通が遮断される。   Referring to FIG. 3, the cover member 16 of the male-side connector 10A is provided with an engaging member 24 that engages with the connected-side main body portion 20 of the female-side connector 10B. The engaging member 24 has a locking claw at the tip of an elastic piece extending in the switch axial direction, and is provided in a locking hole forming part 25 provided at the upper end of the connected side main body part 20 of the female connector 10B. Engageable. The engagement between the engagement member 24 and the locking hole forming portion 25 restricts the disconnection of the male-side connector 10A and the female-side connector 10B. By connecting the two connectors 10A and 10B, the connection terminals 15 and the female terminals 21 are electrically connected, and by separating the connectors 10A and 10B, the connection terminals 15 and the female terminal 21 are electrically disconnected. .

図5を参照し、フットブレーキスイッチ10において、一対の接続端子15間でスイッチ本体部12の端子支持部材17の上端部17Aには、絶縁材料からなる盛部30が設けられている。
盛部30は、一対の接続端子15をこれらの並び方向(対向方向)で結ぶ直線L(図5参照)に対して垂直に交わる断面において、略三角形状の山形の断面形状を形成し、スイッチ前後方向で一対の平面状の傾斜外面30Aを形成している。各傾斜外面30Aは、一対の接続端子15の基端側と交差し、一対の接続端子15よりもスイッチ左右方向の外側まで延びている。各傾斜外面30Aは、盛部30の頂部からスイッチ前後方向の外側へ、前記上端部17Aの外側ほど下方に位置するように傾斜して延びている。この傾斜外面30Aによって、カバー部材16内に上方から浸入した水滴が、一対の接続端子15間に溜まり難くされている。
Referring to FIG. 5, in the foot brake switch 10, a ridge portion 30 made of an insulating material is provided between the pair of connection terminals 15 on the upper end portion 17A of the terminal support member 17 of the switch body portion 12.
The heap portion 30 forms a substantially triangular chevron-shaped cross-sectional shape in a cross section perpendicular to a straight line L (see FIG. 5) that connects the pair of connection terminals 15 in the arrangement direction (opposing direction) of these switches. A pair of flat inclined outer surfaces 30A are formed in the front-rear direction. Each inclined outer surface 30A intersects with the base end side of the pair of connection terminals 15 and extends to the outside of the pair of connection terminals 15 in the left-right direction of the switch. Each of the inclined outer surfaces 30A extends from the top of the raised portion 30 to the outside in the front-rear direction of the switch with an inclination such that the outer side of the upper end 17A is located lower. The inclined outer surface 30 </ b> A makes it difficult for water droplets that have penetrated into the cover member 16 from above to collect between the pair of connection terminals 15.

なお、図6に示す盛部30’のように、上記断面において、上方に凸の略円弧形状の断面形状を形成し、円弧状の傾斜外面30A’を形成する構成としてもよい。盛部30’の傾斜外面30A’は、盛部30’の頂部より外側ほど下方への傾斜が大きくなるよう湾曲した形状となっているので、一対の接続端子15間に浸入した水滴の排出が促進される。   Note that, as in the raised portion 30 ′ shown in FIG. 6, in the above-mentioned cross section, a substantially arcuate cross-sectional shape that is convex upward may be formed to form the arcuate inclined outer surface 30 </ b> A ′. The sloped outer surface 30A ′ of the embossed portion 30 ′ has a curved shape such that the inclination toward the outside of the embossed portion 30 ′ is larger toward the outside, so that the water droplets that have penetrated between the pair of connection terminals 15 can be discharged.

図2、図3、図5、図7を参照し、カバー部材16の下部における四箇所の角部には、一対の傾斜外面30Aのスイッチ本体部12外側の末端をカバー部材16の外部に露出させる開口部31が形成されている。これらの開口部31により、傾斜外面30Aを流下した水滴は、傾斜外面30Aの外側末端でせき止められることなく、カバー部材16の外部に排出される。各開口部31は、カバー部材16内の空間部16Dを外周側のみならず下方に向けても開放しており、カバー部材16内に浸入した水滴をより良好に排出可能としている。   With reference to FIGS. 2, 3, 5, and 7, at the four corners of the lower portion of the cover member 16, the outer ends of the switch body 12 of the pair of inclined outer surfaces 30A are exposed to the outside of the cover member 16. An opening 31 is formed to allow it. By these openings 31, the water droplets flowing down the inclined outer surface 30A are discharged to the outside of the cover member 16 without being stopped at the outer end of the inclined outer surface 30A. Each opening 31 opens the space 16D in the cover member 16 not only on the outer peripheral side but also downward, so that the water droplets that have entered the cover member 16 can be discharged better.

図4、図5、図7、図8を参照し、一対の接続端子15間でスイッチ本体部12の端子支持部材17上には、カバー部材16内の空間部16Dを各接続端子15側に仕切る隔壁32が設けられている。
隔壁32は、各接続端子15と平行な平板状をなし、下端部は盛部30に接続され、前後縁部はカバー部材16の前後内面に接続または密接されている。この隔壁32により、カバー部材16内に水滴が浸入しても、一対の接続端子15間における水滴によるショートが抑止される。
また、隔壁32は、端子支持部材17の盛部30から上方への長さ寸法が、接続端子15のそれよりも大きく設定されており、一対の接続端子15間のショートの虞をより一層低減している。
With reference to FIGS. 4, 5, 7, and 8, a space 16D in the cover member 16 is provided on the terminal support member 17 of the switch body 12 between the pair of connection terminals 15 on the side of each connection terminal 15. A partition wall 32 is provided for partitioning.
The partition wall 32 has a flat plate shape parallel to each connection terminal 15, a lower end portion thereof is connected to the raised portion 30, and front and rear edge portions thereof are connected to or closely attached to the front and rear inner surfaces of the cover member 16. The partition wall 32 suppresses a short circuit due to water droplets between the pair of connection terminals 15 even if water droplets enter the cover member 16.
Further, the partition wall 32 is set such that the length dimension from the raised portion 30 of the terminal support member 17 upward is set to be larger than that of the connection terminal 15, so that the risk of short circuit between the pair of connection terminals 15 is further reduced. are doing.

以上詳細に説明したように、本実施形態のフットブレーキスイッチ10によれば、スイッチ本体部12の上端部17Aから上方に突出して外部端子(雌端子21)を接続可能とする一対の接続端子15の間で、スイッチ本体部12の上端部17Aに、該上端部17Aの外側ほど接続端子15の基端側(下方)に位置するように傾斜する傾斜外面30Aを有する盛部30を設けたので、傾斜外面30Aによって一対の接続端子15間に水滴が溜まり難くすることができる。これにより、一対の接続端子15間の水滴によるショートを抑止し、安定的なスイッチ作動を維持することができる。   As described in detail above, according to the foot brake switch 10 of the present embodiment, the pair of connection terminals 15 that protrude upward from the upper end portion 17A of the switch body 12 and can connect the external terminal (female terminal 21). In between, since the upper end portion 17A of the switch body 12 is provided with the raised portion 30 having the inclined outer surface 30A that is inclined so as to be located closer to the base end side (lower side) of the connection terminal 15 toward the outer side of the upper end portion 17A. The inclined outer surface 30A makes it difficult for water droplets to collect between the pair of connection terminals 15. As a result, a short circuit due to water droplets between the pair of connection terminals 15 can be suppressed, and stable switch operation can be maintained.

また、本実施形態のフットブレーキスイッチ10では、盛部30が、一対の接続端子15の並び方向で、接続端子15の先端側に凸の断面形状をなして延びているので、一対の接続端子15間から良好に排水可能となり、一対の接続端子15間の全体で水滴が溜まることが抑止され、一対の接続端子15間のショートを効果的に抑止することができる。   Further, in the foot brake switch 10 of the present embodiment, the raised portion 30 extends in the direction in which the pair of connection terminals 15 are arranged in a convex cross-sectional shape toward the tip end side of the connection terminals 15, so that the pair of connection terminals is formed.

Since the opening 31 is formed, the cover member 16 can prevent water from splashing on the connection terminal 15 and can satisfactorily discharge the water droplets flowing on the inclined outer surface 30A to the outside of the cover member 16. A short circuit between 15 can be suppressed more effectively.

また、本実施形態のフットブレーキスイッチ10では、角筒状のカバー部材16の周囲の四箇所の角部にそれぞれ開口部31を形成したので、角筒状のカバー部材16で一対の接続端子15の周囲をコンパクトに覆いつつ、カバー部材16内の隅部に水滴が滞留し難くし、かつカバー部材16の何れの側からも排水可能として、一対の接続端子15間のショートをより効果的に抑止することができる。   Further, in the foot brake switch 10 of the present embodiment, the openings 31 are formed at four corners around the rectangular tubular cover member 16, so that the pair of connection terminals 15 are formed by the rectangular tubular cover member 16. While covering the periphery of the cover member in a compact manner, water droplets are unlikely to stay in the corners of the cover member 16, and drainage is possible from any side of the cover member 16, so that a short circuit between the pair of connection terminals 15 is more effective. Can be deterred.

また、本実施形態のフットブレーキスイッチ10では、一対の接続端子15間で盛部30上に、カバー部材16内の空間部16Dを仕切る隔壁32を設けたので、カバー部材16内に水滴が残留しても、この水滴による一対の接続端子15間のショートを抑止することができる。   Further, in the foot brake switch 10 of the present embodiment, since the partition wall 32 that partitions the space 16D in the cover member 16 is provided on the raised portion 30 between the pair of connection terminals 15, water droplets remain in the cover member 16. Even in this case, however, it is possible to prevent a short circuit between the pair of connection terminals 15 due to this water droplet.

なお、本発明は上記実施形態に限られるものではなく、例えば図9に示すように、一対の接続端子15を囲むカバー部材16の一側面を、ヒンジ16Aを介して開閉可能な扉部16Bとした構成としてもよい。この場合、扉部16Bを開いてカバー部材16内の接続端子15の状況を容易に目視で確認可能となり、メンテナンス性を向上できる。扉部16Bには、閉状態を維持する係止片16Cを設けることが好ましい。
スイッチ回路14は、ロッド13のストロークによりON/OFFを切り替えるものであるが、例えばロッド13のストロークにより電気的な信号を出力するスイッチ素子であってもよい。
そして、上記実施形態における構成は本発明の一例であり、実施形態の構成要素を周知の構成要素に置き換える等、本発明の要旨を逸脱しない範囲で種々の変更が可能である。
