Description
【０００１】[0001]
本考案は、車両等の燃料タンク内の液量を測定する液量検出装置に関し、特に 絶縁基板の導体電極に関する。 The present invention relates to a liquid amount detection device for measuring the amount of liquid in a fuel tank of a vehicle or the like, and particularly to a conductor electrode on an insulating substrate.
【０００２】[0002]
従来、液量検出装置は、燃料タンク１内に導体電極２と抵抗体３とがセラミッ ク等よりなる絶縁基板４上に印刷により形成され、さらに導体電極２上を摺動す る摺動接点５を備えた摺動体６とが設けられ、この摺動体６は、燃料の液面に応 じて上下動するフロート７からアーム８を介して絶縁基板４上を前記液面に応じ て可動するように接続されている。従って、液面の上下動がフロート７とアーム ８とを介して摺動体６に伝達され、摺動接点５が導体電極２上を摺動することに より絶縁基板４上の導通電極２と摺動接点５とが接触し、その接触した導通電極 ２の位置により抵抗値が変化し、その変化を表示器（図示しない）で表示してい た（例えば、実開昭６２−３４３２８号公報参照）。 Conventionally, a liquid amount detecting device is a sliding contact in which a conductor electrode 2 and a resistor 3 are formed by printing on an insulating substrate 4 made of ceramic or the like in a fuel tank 1, and further sliding on the conductor electrode 2. 5 is provided with a sliding body 6 which moves vertically on the insulating substrate 4 via an arm 8 from a float 7 which moves up and down in response to the liquid surface of the fuel according to the liquid surface. Are connected as. Therefore, the vertical movement of the liquid surface is transmitted to the sliding body 6 via the float 7 and the arm 8, and the sliding contact 5 slides on the conductor electrode 2 to slide on the conductive electrode 2 on the insulating substrate 4. The contact point with the moving contact 5 changes the resistance value depending on the position of the contacting conductive electrode 2, and the change is displayed on a display (not shown) (for example, see Japanese Utility Model Laid-Open No. 62-34328). .
【０００３】[0003]
しかし、従来の液量検出装置においては、フロート７，アーム８，絶縁基板４ 等の構成部品には少なからず寸法誤差が生じ、さらに絶縁基板４上の導通電極２ 等にも印刷位置ズレが生じるので、たとえば本来の燃料の残量が１／２であるに もかかわらず、摺動体６の摺動接点５が前記残量に応じた抵抗値を出す絶縁基板 ４上の導体電極２に接触しないため、表示器が残量１／２を示さないという問題 点が生じている。 However, in the conventional liquid amount detection device, a dimensional error is caused in the components such as the float 7, the arm 8 and the insulating substrate 4, and a printing position shift is also generated in the conductive electrode 2 and the like on the insulating substrate 4. Therefore, for example, the sliding contact 5 of the sliding body 6 does not come into contact with the conductor electrode 2 on the insulating substrate 4 that produces a resistance value according to the remaining amount even if the original remaining amount of fuel is 1/2. Therefore, there is a problem that the display does not show 1/2 of the remaining amount.
【０００４】[0004]
そこで本考案は前記の問題点に着目し、構成部品に多少の寸法誤差があったと しても、たとえば燃料の残量が１／２の時には表示器においても正確に１／２を 示す液量検出装置を提供することを目的とするもので、絶縁基板上に適宜間隔を おいて複数列の導体電極を備え、その導体電極上を摺動接点を備えた摺動体が摺 動し、かつ前記導体電極の一部を抵抗体が導体電極上を複数列に渡って被着した 液量検出装置において、ある一つの導体電極とその導体電極と隣り合う少なくと も１つの導体電極とを、摺動接点が摺動しない部分で電気的に接続したものであ る。 Therefore, the present invention pays attention to the above-mentioned problems, and even if there is some dimensional error in the component parts, for example, when the remaining amount of fuel is 1/2, the liquid amount which accurately shows 1/2 even in the indicator. An object of the present invention is to provide a detection device, wherein a plurality of rows of conductor electrodes are provided on an insulating substrate at appropriate intervals, a sliding body having sliding contacts slides on the conductor electrodes, and In a liquid amount detection device in which a resistor covers a part of a conductor electrode over a plurality of rows on the conductor electrode, a conductor electrode and at least one conductor electrode adjacent to the conductor electrode are slidable. It is an electrical connection where the moving contact does not slide.

正確に残量を表示したい液量の導体電極、例えば１／２の残量を示す導体電極 と、その導体電極と隣り合う導体電極とを電気的に接続したことにより、フロー ト，アーム，絶縁基板等に規格内での寸法誤差や絶縁基板等の印刷ズレが生じた としても、正確に残量を表示したい液量について、正確な液量の表示をおこなう ことができる。 By electrically connecting the conductor electrode of the liquid amount for which it is desired to accurately display the remaining amount, for example, the conductor electrode showing the remaining amount of 1/2 and the conductor electrode adjacent to the conductor electrode, the float, arm, and insulation Even if there is a dimensional error within the standard on the board, or a printing deviation of the insulating board, etc., it is possible to accurately display the amount of liquid for which it is desired to accurately display the remaining amount.
【０００６】[0006]
以下、本考案について図１，２に基づき説明するが、前記従来例と同一個所に は同一符号を付してその詳細な説明は省く。 The present invention will be described below with reference to FIGS.
【０００７】 図１は本考案の液量検出装置を燃料タンクに取り付けた図、図２は同考案の液 量検出装置の正面図である。FIG. 1 is a view in which the liquid amount detecting device of the present invention is attached to a fuel tank, and FIG. 2 is a front view of the liquid amount detecting device of the present invention.
【０００８】 図１，２で示すように、本考案の液量検出装置は、セラミックよりなる絶縁基 板４上に適宜間隔をおいて、複数列の導体電極２を扇形に印刷により形成し、か つ導体電極２の一部を抵抗体３が複数列に渡って印刷により被着している。ここ で例えば液量の残量が１／２を示す導体電極２とその導体電極２と隣り合う導体 電極２とを、摺動接点５が導体電極２と接触しない部位で電気的に接続する。As shown in FIGS. 1 and 2, the liquid amount detecting device of the present invention has a plurality of rows of conductor electrodes 2 formed by printing in a fan shape on an insulating base plate 4 made of ceramic at appropriate intervals. The resistor 3 is attached to a part of the upper conductor electrode 2 by printing over a plurality of rows. Here, for example, the conductor electrode 2 having a remaining liquid amount of 1/2 and the conductor electrode 2 adjacent to the conductor electrode 2 are electrically connected at a portion where the sliding contact 5 does not come into contact with the conductor electrode 2.
【０００９】 すなわち、フロート７，アーム８，絶縁基板４等の寸法誤差と絶縁基板４の印 刷位置ズレとによって、本来残量が１／２であるのに摺動接点５が１／２を示す 導体電極２と接触していない場合においても、１／２を示す導体電極２とその導 体電極２と隣り合う導体電極２とを電気的に接続しているので、仮に摺動接点５ が１／２の導体電極２からズレていたとしても、両隣りの導体電極２のどちらか 一方と接触するので、表示器において正確に１／２を示す。That is, due to the dimensional error of the float 7, the arm 8, the insulating substrate 4 and the like and the printing position shift of the insulating substrate 4, the sliding contact 5 is reduced to 1/2 even though the remaining amount is originally 1/2. Even when it is not in contact with the conductor electrode 2 shown, the conductor electrode 2 showing 1/2 and the conductor electrode 2 adjacent to the conductor electrode 2 are electrically connected. Even if it deviates from the conductor electrode 2 of 1/2, since it comes into contact with either one of the conductor electrodes 2 adjacent to each other, it accurately shows 1/2 on the display.
【００１０】 なお、実施例では、液量の残量が１／２の場合であったがこれは適宜変更可能 で任意に設定してよい。In the embodiment, the remaining amount of liquid is 1/2, but this can be changed appropriately and may be set arbitrarily.
【００１１】 また、図示はしていないが、摺動接点５が導体電極２と接触するところ以外で あれば、導体電極２と導体電極２とはどこで電気的に接続されていてもかまわな い。Although not shown, the conductor electrode 2 and the conductor electrode 2 may be electrically connected to each other as long as the sliding contact 5 is not in contact with the conductor electrode 2. .
【００１２】[0012]
以上、本考案によれば、液量検出装置の構成部品に多少の寸法誤差等があった としても、正確に表示したい液量の残量を、正確に表示することができる。 As described above, according to the present invention, even if there are some dimensional errors or the like in the components of the liquid amount detection device, it is possible to accurately display the remaining amount of the liquid amount to be displayed accurately.
【００１３】 また、ある導体電極とその導体電極と隣り合う導体電極とを、摺動接点が導体 電極と接触しない部位で電気的に接続することにより、導体電極２の厚みが厚く ならなくて済むため、摺動接点５の摺動を滑らかにおこなうことができる。Further, by electrically connecting a conductor electrode and a conductor electrode adjacent to the conductor electrode at a portion where the sliding contact does not contact the conductor electrode, the thickness of the conductor electrode 2 does not have to be thick. Therefore, the sliding contact 5 can be smoothly slid.
