Description

本発明は、電磁スイッチ装置に関し、特に、二輪車に搭載されるスタータモータ用電磁スイッチ装置等に用いられる車載用の電磁スイッチ装置に関する。   The present invention relates to an electromagnetic switch device, and more particularly to an in-vehicle electromagnetic switch device used for a starter motor electromagnetic switch device mounted on a two-wheeled vehicle.

車載電装品、特に、二輪車用のものは、取付スペースに余裕がないことから、小型で、嵩ばらないコンパクト性に優れていることを要求される。このことに対して、スタータマグネットスイッチと呼ばれるスタータモータ用の電磁スイッチ装置の端子ホルダ部分に、スタータモータ回路とは別の主電気回路のメインヒューズが取り付けられるヒューズ接続端子対を有するヒューズボックス構造を組み込み、電装品全体（電磁スイッチ装置とヒューズボックス）としての小型化を図ったヒューズ接続部付きの電磁スイッチ装置がある（例えば、特許文献１）。
特開昭６１−８５７４６号公報 In-vehicle electrical components, particularly those for two-wheeled vehicles, are required to be small and excellent in compactness because they do not have a sufficient mounting space. On the other hand, a fuse box structure having a fuse connection terminal pair in which a main fuse of a main electric circuit different from a starter motor circuit is attached to a terminal holder portion of an electromagnetic switch device for a starter motor called a starter magnet switch. There is a built-in electromagnetic switch device with a fuse connecting portion that is miniaturized as an entire electrical component (electromagnetic switch device and fuse box) (for example, Patent Document 1).
JP-A-61-85746

上述のようなヒューズ接続部付き電磁スイッチ装置においても、常時通電のヒューズ接続端子部分の電気抵抗により、通電時にヒューズ接続端子部分が発熱することが避けられない。このことに対して、ヒューズ接続部付き電磁スイッチ装置は、車載電装品としての小型化設計のために、ヒューズ接続端子が小さく、表面積が小さいため、放熱性が悪い。   Even in the electromagnetic switch device with a fuse connection portion as described above, it is inevitable that the fuse connection terminal portion generates heat during energization due to the electrical resistance of the fuse connection terminal portion that is normally energized. On the other hand, the electromagnetic switch device with a fuse connection part has a poor heat dissipation because the fuse connection terminal is small and the surface area is small because of the miniaturization design as an in-vehicle electrical component.

二輪車でも、燃料噴射やブレーキ系の電子制御化により車載の電気系統が増える傾向があり、一系統の主電気回路だけでは、それらに対する電力供給を賄いきれないことや、信頼性向上のために、これらの電気回路を多系統化し、その各電気回路をヒューズ付き回路とすることが考えられている。   Even in motorcycles, there is a tendency for in-vehicle electric systems to increase due to fuel injection and electronic control of the brake system, and it is impossible to cover the power supply for them with only one main electric circuit, and to improve reliability, It is considered that these electric circuits are multi-systemed and each electric circuit is a circuit with a fuse.

このようなヒューズ付き回路の多系統化に対応して、ヒューズ接続部付き電磁スイッチ装置に各系統のヒューズを取り付けようとすると、端子ホルダ部分に、各系統ごとに複数対のヒューズ接続端子を取り付けなくてはならず、ヒューズ接続部付き電磁スイッチ装置の大型化を避けると、各ヒューズ接続端子が更に小さいものになる。このため、ヒューズ接続端子の表面積が更に小さくなり、放熱性が悪化し、熱負荷が大きくなり、電磁スイッチ装置の電気性能、耐久性に悪影響を及ぼす度合いが増加する。   Corresponding to the multi-system of such a circuit with fuses, if you try to install fuses of each system to the electromagnetic switch device with fuse connection part, attach multiple pairs of fuse connection terminals for each system to the terminal holder part If the size of the electromagnetic switch device with a fuse connection portion is to be avoided, each fuse connection terminal becomes even smaller. For this reason, the surface area of the fuse connection terminal is further reduced, heat dissipation is deteriorated, the heat load is increased, and the degree of adverse effects on the electrical performance and durability of the electromagnetic switch device is increased.

本発明が解決しようとする課題は、ヒューズ接続端子等の寄生の接続端子（別電気回路用の接続端子）の放熱性能を改善し、別電気回路用の接続端子が小型化されても、電磁スイッチ装置の電気性能、耐久性が悪化することを回避、低減することである。   The problem to be solved by the present invention is to improve the heat dissipation performance of parasitic connection terminals (connection terminals for separate electric circuits) such as fuse connection terminals, and even if the connection terminals for separate electric circuits are reduced in size, This is to avoid or reduce deterioration of the electrical performance and durability of the switch device.

本発明による電磁スイッチ装置は、電磁コイル、プランジャ、接点部材を含む電磁スイッチを内蔵し、前記電磁スイッチによって電気的に断続される電源端子とスイッチ出力端子とを設けられたスイッチケーシングの上端部に端子ホルダが取り付けられており、前記端子ホルダに、電磁スイッチとは別の電気回路のための接続端子が取り付けられている電磁スイッチ装置であって、前記端子ホルダは前記スイッチケーシングとの間に下方開放の空隙を画定しており、前記接続端子には前記空隙に進入した放熱片部が延設されている。   An electromagnetic switch device according to the present invention incorporates an electromagnetic switch including an electromagnetic coil, a plunger, and a contact member, and is provided at an upper end portion of a switch casing provided with a power supply terminal and a switch output terminal that are electrically interrupted by the electromagnetic switch. A terminal holder is attached, and a connection terminal for an electric circuit different from the electromagnetic switch is attached to the terminal holder, wherein the terminal holder is disposed below the switch casing. An open space is defined, and the connecting terminal is provided with a heat dissipating piece extending into the space.

また、本発明による電磁スイッチ装置は、電磁コイル、プランジャ、接点部材を含む電磁スイッチを内蔵し、前記電磁スイッチによって電気的に断続される電源端子とスイッチ出力端子とを設けられたスイッチケーシングの上端部に端子ホルダが取り付けられており、前記端子ホルダに、前記電源端子に導電接続された電源側ヒューズ接続端子と、ヒューズ回路用出力端子部を一体に有する出力側ヒューズ接続端子とで対をなす少なくとも一対のヒューズ接続端子とが取り付けられているヒューズ接続部付き電磁スイッチ装置であって、前記端子ホルダは、前記スイッチケーシングとの間に下方開放の空隙を画定しており、前記ヒューズ接続端子の少なくとも一つには前記空隙に進入した放熱片部が延設されている。   An electromagnetic switch device according to the present invention includes an electromagnetic switch including an electromagnetic coil, a plunger, and a contact member, and an upper end of a switch casing provided with a power supply terminal and a switch output terminal that are electrically interrupted by the electromagnetic switch. A terminal holder is attached to the terminal, and the terminal holder is paired with a power supply side fuse connection terminal conductively connected to the power supply terminal and an output side fuse connection terminal integrally having a fuse circuit output terminal part. An electromagnetic switch device with a fuse connection portion to which at least a pair of fuse connection terminals is attached, wherein the terminal holder defines a gap that is open downward between the switch casing and the fuse connection terminal. At least one of the heat dissipating pieces that have entered the gap is extended.

本発明による電磁スイッチ装置は、好ましくは、前記端子ホルダに、前記対をなすヒューズ接続端子が、二対、設けられている。   In the electromagnetic switch device according to the present invention, preferably, the terminal holder is provided with two pairs of the fuse connection terminals forming the pair.

本発明によるヒューズ接続部付き電磁スイッチ装置は、更に好ましくは、前記端子ホルダは前記スイッチケーシングの外周壁との間に前記空隙を画定する外周側壁部を有し、前記放熱片部は一方の面が前記外側周壁部の内側の面に接した状態で前記空隙に進入し、前記外側周壁部の補強部材を兼ねている。   More preferably, in the electromagnetic switch device with a fuse connecting portion according to the present invention, the terminal holder has an outer peripheral side wall portion that defines the gap between the terminal holder and an outer peripheral wall of the switch casing, and the heat radiating piece portion has one surface. Enters the gap in contact with the inner surface of the outer peripheral wall portion, and also serves as a reinforcing member for the outer peripheral wall portion.

本発明による電磁スイッチ装置によれば、スイッチケーシングと端子ホルダとの間の下方開放の空隙に、ヒューズ接続端子等の別電気回路用の接続端子より延設された放熱片部が進入していることにより、当該接続端子の自然放熱が活発になり、接続端子の放熱性能が改善され、熱負荷の軽減が図られる。これにより、熱による電磁スイッチ装置の電気性能、耐久性の悪化が回避、低減される。   According to the electromagnetic switch device of the present invention, the heat dissipating piece extending from the connection terminal for another electric circuit such as the fuse connection terminal is inserted into the lower open gap between the switch casing and the terminal holder. As a result, natural heat dissipation of the connection terminal becomes active, the heat dissipation performance of the connection terminal is improved, and the thermal load is reduced. Thereby, the deterioration of the electrical performance and durability of the electromagnetic switch device due to heat is avoided and reduced.

以下に、本発明による電磁スイッチ装置を二輪車のスタータマグネットスイッチに適用した一つの実施形態を、図１〜図５を参照して説明する。   Hereinafter, an embodiment in which an electromagnetic switch device according to the present invention is applied to a starter magnet switch of a motorcycle will be described with reference to FIGS.

スタータマグネットスイッチ１０は、プラスチックス等の電気絶縁性のスイッチケーシング１１と、スイッチケーシング１１の上端部に取り付けられたプラスチックス等の電気絶縁性の端子ホルダ１２を有する。   The starter magnet switch 10 includes an electrically insulating switch casing 11 such as plastics and an electrically insulating terminal holder 12 such as plastics attached to the upper end of the switch casing 11.

スイッチケーシング１１は、電磁コイル１３、プランジャ１４、固定接点部材１５、１６、可動接点部材１７を含む電磁スイッチ１８を密封内蔵している。電磁スイッチ１８は、電磁コイル１３が励磁することにより、可動接点部材１７によって固定接点部材１５と１６とを導通接続し、電磁コイル１３が消磁することにより、可動接点部材１７を固定接点部材１５、１６より切り離して固定接点部材１５と１６との導通を遮断する。電磁コイル１３の通電用の電極端子１３Ａ、１３Ｂは、スイッチケーシング１１の上端部より上方に突出している。   The switch casing 11 hermetically incorporates an electromagnetic switch 18 including an electromagnetic coil 13, a plunger 14, fixed contact members 15 and 16, and a movable contact member 17. When the electromagnetic coil 13 is excited, the electromagnetic switch 18 electrically connects the fixed contact members 15 and 16 with the movable contact member 17 and demagnetizes the electromagnetic coil 13 so that the movable contact member 17 is connected to the fixed contact member 15. The continuity between the fixed contact members 15 and 16 is cut off by disconnecting from 16. Electrode terminals 13 </ b> A and 13 </ b> B for energization of the electromagnetic coil 13 protrude upward from the upper end portion of the switch casing 11.

スイッチケーシング１１には、固定接点部材１５と導電接続されている電源端子１９と、固定接点部材１６と導電接続されているスイッチ出力端子２０が設けられている。電源端子１９の上端部１９Ａと、スイッチ出力端子２０の上端部２０Ａは、各々スイッチケーシング１１の上端部１１Ａより外部に突出露呈している。電源端子１９の上端部１９Ａにはバッテリ電源１００が電気的に接続され、スイッチ出力端子２０の上端部２０Ａには、スタータモータ１０１が電気的に接続される。   The switch casing 11 is provided with a power supply terminal 19 that is conductively connected to the fixed contact member 15 and a switch output terminal 20 that is conductively connected to the fixed contact member 16. The upper end portion 19 </ b> A of the power terminal 19 and the upper end portion 20 </ b> A of the switch output terminal 20 are exposed to the outside from the upper end portion 11 </ b> A of the switch casing 11. The battery power supply 100 is electrically connected to the upper end portion 19A of the power supply terminal 19, and the starter motor 101 is electrically connected to the upper end portion 20A of the switch output terminal 20.

端子ホルダ１２には、電源端子１９に導電接続された二つの電源側ヒューズ接続端子３１、３２を有するヒューズ接続金具３３と、ヒューズ回路用出力端子３４を一体に有し一方の電源側ヒューズ接続端子３１とで一対のヒューズ接続端子をなす出力側ヒューズ接続端子３５と、ヒューズ回路用出力端子３６を一体に有し他方の電源側ヒューズ接続端子３２とでもう一対のヒューズ接続端子をなす出力側ヒューズ接続端子３７とが取り付けられている。   The terminal holder 12 is integrally provided with a fuse connection bracket 33 having two power supply side fuse connection terminals 31 and 32 electrically connected to the power supply terminal 19 and a fuse circuit output terminal 34, and one power supply side fuse connection terminal. An output side fuse connection terminal 35 which forms a pair of fuse connection terminals with the output terminal 31 and an output side fuse which forms a pair of fuse connection terminals with the other power supply side fuse connection terminal 32 having the fuse circuit output terminal 36 integrally. A connection terminal 37 is attached.

対をなす電源側ヒューズ接続端子３１と出力側ヒューズ接続端子３５には、一つのブレードヒューズ４０が導電接続される。詳細には、ブレードヒューズ４０は、脚片状の二つの接続片４０Ａ、４０Ｂを有し、接続片４０Ａ、４０Ｂを、電源側ヒューズ接続端子３１と出力側ヒューズ接続端子３５の各々に装着されたばね端子金具３８によって、電源側ヒューズ接続端子３１と出力側ヒューズ接続端子３５に対して抜き差し可能に導電接続される。そして、ヒューズ回路用出力端子部３４に、ライト等の電気負荷１０２が接続されることにより、ヒューズ付きの一つの電気系統が構成される。   One blade fuse 40 is conductively connected to the pair of power supply side fuse connection terminal 31 and output side fuse connection terminal 35. More specifically, the blade fuse 40 has two leg-like connection pieces 40A and 40B, and the connection pieces 40A and 40B are attached to the power supply side fuse connection terminal 31 and the output side fuse connection terminal 35, respectively. The terminal fitting 38 is conductively connected to the power supply side fuse connection terminal 31 and the output side fuse connection terminal 35 so as to be removable. Then, an electrical load 102 such as a light is connected to the fuse circuit output terminal portion 34, thereby forming one electrical system with a fuse.

もう一つの対をなす電源側ヒューズ接続端子３２と出力側ヒューズ接続端子３７には、もう一つのブレードヒューズ４１が導電接続される。ブレードヒューズ４１も、脚片状の二つの接続片４１Ａ、４１Ｂを有し、接続片４１Ａ、４１Ｂを、電源側ヒューズ接続端子３２と出力側ヒューズ接続端子３７の各々に装着されたばね端子部材３９によって、電源側ヒューズ接続端子３２と出力側ヒューズ接続端子３７に対して抜き差し可能に導電接続される。そして、ヒューズ回路用出力端子部３６に、燃料噴射弁等の別の電気負荷１０３が接続されることにより、ヒューズ付きのもう一つの電気系統が構成される。   Another blade fuse 41 is conductively connected to the power supply side fuse connection terminal 32 and the output side fuse connection terminal 37 forming another pair. The blade fuse 41 also has two leg-like connection pieces 41A and 41B, and the connection pieces 41A and 41B are attached by spring terminal members 39 attached to the power supply side fuse connection terminal 32 and the output side fuse connection terminal 37, respectively. The power supply side fuse connection terminal 32 and the output side fuse connection terminal 37 are conductively connected so as to be removable. Then, another electric load 103 such as a fuel injection valve is connected to the fuse circuit output terminal portion 36, thereby forming another electric system with a fuse.

なお、出力側ヒューズ接続端子３５、電源側ヒューズ接続端子３１、電源側ヒューズ接続端子３２、出力側ヒューズ接続端子３７は、当該順序で、左右方向に一列に揃えられた整列配置になっている。   The output side fuse connection terminal 35, the power source side fuse connection terminal 31, the power source side fuse connection terminal 32, and the output side fuse connection terminal 37 are arranged in a line in the left-right direction in this order.

出力側ヒューズ接続端子３５、３７は、各々プレス成形品であり、左右外縁側に放熱片部３５Ａ、３５Ｂ、３７Ａ、３７Ｂが延設されている。放熱片部３５Ａ、３５Ｂ、３７Ａ、３７Ｂは、出力側ヒューズ接続端子３５、３７の水平主部３５Ｃ、３７Ｃより下方に折れ曲がった屈曲片として構成されている。   Each of the output side fuse connection terminals 35 and 37 is a press-molded product, and heat dissipating pieces 35A, 35B, 37A, and 37B are extended on the left and right outer edges. The heat dissipating pieces 35A, 35B, 37A, 37B are configured as bent pieces bent downward from the horizontal main portions 35C, 37C of the output side fuse connecting terminals 35, 37.

端子ホルダ１２は、当該ホルダの左右両部を縁取りする外周側壁部１２Ａ、１２Ｂを垂下成形されている。外周側壁部１２Ａ、１２Ｂは、スイッチケーシング１１の左右の外周壁１１Ａ、１１Ｂより外側にあり、スイッチケーシング１１の外周壁１１Ａ、１１Ｂとの間に、下方開放のスリット状の空隙５１、５２を画定している。この空隙５１、５２には、出力側ヒューズ接続端子３５、３７の放熱片部３５Ａ、３７Ａが進入している。空隙５１、５２はスイッチケーシング１１の上端面と端子ホルダ１２の下底面との間に連続した空間として拡大されている。この拡大部分に放熱片部３５Ｂ、３７Ｂが進入している。   The terminal holder 12 is formed by drooping outer peripheral side wall portions 12A and 12B that border both left and right portions of the holder. The outer peripheral side wall portions 12A and 12B are outside the left and right outer peripheral walls 11A and 11B of the switch casing 11, and define downwardly opened slit-like gaps 51 and 52 between the outer peripheral walls 11A and 11B of the switch casing 11. is doing. The heat radiation pieces 35A and 37A of the output side fuse connection terminals 35 and 37 enter the gaps 51 and 52, respectively. The gaps 51 and 52 are enlarged as a continuous space between the upper end surface of the switch casing 11 and the lower bottom surface of the terminal holder 12. The heat radiating piece portions 35B and 37B enter the enlarged portion.

放熱片部３５Ａ、３５Ｂ、３７Ａ、３７Ｂが下方開放の空隙５１、５２において大気中に曝されていることにより、出力側ヒューズ接続端子３５、３７の自然放熱が活発になる。放熱片部３５Ａ、３７Ａは、スイッチケーシング１１の外周壁１１Ａ、１１Ｂに沿う垂直方向に屈曲形成されているから、電磁スイッチ装置を大型化することなく、出力側ヒューズ接続端子３５、３７の表面積を増やすことができる。これらのことにより、出力側ヒューズ接続端子３５、３７の放熱性能が改善され、熱負荷の軽減が図られる。   Since the heat radiating pieces 35A, 35B, 37A, and 37B are exposed to the atmosphere in the gaps 51 and 52 that are open downward, natural heat dissipation of the output-side fuse connection terminals 35 and 37 becomes active. Since the heat dissipating pieces 35A and 37A are bent in the vertical direction along the outer peripheral walls 11A and 11B of the switch casing 11, the surface area of the output side fuse connection terminals 35 and 37 can be increased without increasing the size of the electromagnetic switch device. Can be increased. As a result, the heat radiation performance of the output side fuse connection terminals 35 and 37 is improved, and the thermal load is reduced.

これにより、ヒューズ付き回路の２系統化によって端子ホルダ１２に設置されるヒューズ接続端子が、本実施形態のように、二対になり、装置全体の大型化を避けるために、ヒューズ接続端子が一対タイプのものに比して小型化されても、ヒューズ接続部の発熱による電磁スイッチ装置１０の電気性能、耐久性の悪化が回避、低減される。   As a result, the fuse connection terminals installed in the terminal holder 12 by the two systems of the circuit with fuses become two pairs as in this embodiment, and in order to avoid an increase in the size of the entire apparatus, a pair of fuse connection terminals is provided. Even if the size is reduced as compared with the type, the deterioration of the electrical performance and durability of the electromagnetic switch device 10 due to the heat generated in the fuse connecting portion can be avoided and reduced.

この場合の放熱片部３５Ａ、３７Ａの折り曲げ長さは、出力側ヒューズ接続端子３５、３７の温度特性に応じて適当値に設定されればよく、スイッチケーシング１１の高さ範囲内であれば、当該放熱片部３５Ａ、３７Ａの折り曲げ長さは長くてよく、これが電磁スイッチ装置を大型化することがない。   In this case, the bending length of the heat dissipating pieces 35A and 37A may be set to an appropriate value according to the temperature characteristics of the output side fuse connection terminals 35 and 37, and if within the height range of the switch casing 11, The bending length of the heat dissipating pieces 35A and 37A may be long, and this does not increase the size of the electromagnetic switch device.

放熱片部３５Ａ、３７Ａは、外周側壁部１２Ａ、１２Ｂの内側にあって、外部に露呈していないので、保護が図られ、放熱片部３５Ａ、３７Ａが外部の導体に接触することによる短絡、地絡を生じることを未然に防止できる。   Since the heat dissipating pieces 35A and 37A are inside the outer peripheral side walls 12A and 12B and are not exposed to the outside, protection is achieved, and the heat dissipating pieces 35A and 37A come into contact with external conductors, It is possible to prevent a ground fault from occurring.

As a result, the heat dissipating pieces 35A and 37A also serve as reinforcing members for the outer peripheral wall portions 12A and 12B, the outer peripheral wall portions 12A and 12B are reinforced, and the outer peripheral wall portions 12A and 12B are prevented from being deformed or damaged. it can.

上述の実施形態では、出力側ヒューズ接続端子３５、３７が外側配置になっているので、出力側ヒューズ接続端子３５、３７に放熱片部３５Ａ、３７Ａを設けたが、電源側ヒューズ接続端子３１、３２が外側配置の場合には、電源側ヒューズ接続端子３１、３２に放熱片部
３５Ａ、３７Ａと同等の放熱片部が設けられればよい。また、これら放熱片部は、片側のヒューズ接続端子にのみ設けられていてもよい。 In the above-described embodiment, since the output side fuse connection terminals 35 and 37 are arranged outside, the output side fuse connection terminals 35 and 37 are provided with the heat radiation pieces 35A and 37A. When 32 is arranged outside, it is only necessary that the heat-dissipating piece portions equivalent to the heat-dissipating piece portions 35 </ b> A and 37 </ b> A are provided on the power supply side fuse connection terminals 31 and 32. Moreover, these heat radiating piece parts may be provided only on the fuse connecting terminal on one side.

なお、上述の実施形態の説明では、上部、下方、左右、水平、垂直と云う語句を使用したが、これは、ヒューズ接続部付き電磁スイッチ装置１０が図２に示されている天地位置にある場合の方向等を示す説明の便宜上の語句であり、ヒューズ接続部付き電磁スイッチ装置が、実際の取付姿勢で、図２に示されている天地位置より上下反転、横転、傾斜されれば、それに見合って相対的に変わるものである。   In the description of the above-described embodiment, the terms “upper”, “lower”, “left / right”, “horizontal”, and “vertical” are used. It is a term for convenience of explanation indicating the direction of the case, and if the electromagnetic switch device with a fuse connection part is inverted upside down, overturned and inclined from the top and bottom position shown in FIG. It changes relatively in proportion.
