Abstract

PROBLEM TO BE SOLVED: To prevent intrusion of water due to a respiratory phenomenon in an injector configured to take out a lead wire from the upper end opening of an injector body.SOLUTION: An opening 31 where a lead wire 8 is taken out is sealed with a cap 4 formed of a metal or a resin, the lead wire 8 is inserted into an insertion hole 41 formed in the cap 4, and a space between the lead wire 8 and the insertion hole 41 is sealed with a sealing member 9. By raising the upper end face 91 of the sealing member 9 higher than the upper end face 42 of the cap 4, and by raising the upper face 42 of the cap 4 higher than the upper end face 32 of a body 1, water on the upper end face 91 of the sealing member 9 falls by gravity in the upper end face 42 side of the cap 4, subsequently falls in the upper end face 32 side of the upper body 3, and further falls in the outer peripheral face side of the upper body 3. Accordingly, water does not remain on each of the upper end faces 32, 42, 91, and the intrusion of water due to the respiratory phenomenon can be prevented.

Description

本発明は、内燃機関に燃料を噴射するインジェクタに関するものである。   The present invention relates to an injector that injects fuel into an internal combustion engine.

内燃機関に燃料を噴射するインジェクタとして、内燃機関に噴射される燃料の圧力を検出する圧力センサを、インジェクタのボデー内に配置するものが提案されている。また、インジェクタのボデーにコネクタが設けられ、コネクタのターミナルと圧力センサが電気的に接続されている（例えば、特許文献１参照）。   As an injector for injecting fuel into an internal combustion engine, an injector is proposed in which a pressure sensor for detecting the pressure of fuel injected into the internal combustion engine is disposed in the body of the injector. Further, a connector is provided on the body of the injector, and the terminal of the connector and the pressure sensor are electrically connected (for example, see Patent Document 1).

特開２０１０−２４２５７４号公報JP 2010-242574 A

ところで、本発明者らは、上記した従来のコネクタを廃止し、圧力センサに電気的に接続したリード線をインジェクタのボデーの上端に設けられた開口部から取り出す構成のインジェクタを検討した。   By the way, the present inventors examined an injector having a configuration in which the above-described conventional connector is abolished and a lead wire electrically connected to the pressure sensor is taken out from an opening provided at the upper end of the body of the injector.

図４は、リード線を使用するインジェクタの検討案であり、インジェクタのロアボデー１とアッパーボデー３とによって形成された空間に圧力センサ６を配置している。そして、その空間への水浸入を防止するために、アッパーボデー３の上端に設けたリード線取り出し用の開口部３１を、ゴム製の蓋１００で覆うようにしている。この蓋１００は、有底円筒状になっており、底部壁面１０１に形成された通し孔１０２にリード線８が挿入され、外周の筒部１０３がアッパーボデー３に嵌合される。   FIG. 4 shows an examination plan for an injector using a lead wire, in which a pressure sensor 6 is arranged in a space formed by the lower body 1 and the upper body 3 of the injector. In order to prevent water from entering the space, the opening 31 for taking out the lead wire provided at the upper end of the upper body 3 is covered with a rubber lid 100. The lid 100 has a bottomed cylindrical shape, the lead wire 8 is inserted into a through hole 102 formed in the bottom wall surface 101, and the outer cylinder portion 103 is fitted to the upper body 3.

しかしながら、このインジェクタの構成では、蓋１００をアッパーボデー３に組み付けた状態において、底部壁面１０１の通し孔１０２付近が底部壁面１０２の外周側よりも下方になる虞がある。この場合、底部壁面１０１上に水が溜まるため、圧力センサ設置空間と外部との圧力差による呼吸現象によって、底部壁面１０１上の水がリード線８と通し孔１０２の隙間を介して圧力センサ設置空間に浸入してしまうという問題が発生する。   However, in the configuration of this injector, there is a possibility that the vicinity of the through hole 102 of the bottom wall surface 101 is lower than the outer peripheral side of the bottom wall surface 102 when the lid 100 is assembled to the upper body 3. In this case, since water accumulates on the bottom wall surface 101, the water on the bottom wall surface 101 is installed through the gap between the lead wire 8 and the through hole 102 due to a respiration phenomenon caused by a pressure difference between the pressure sensor installation space and the outside. The problem of entering the space occurs.

本発明は上記点に鑑みて、リード線をインジェクタのボデーの上端開口部から取り出す構成のインジェクタにおいて、呼吸現象による水の浸入を防止することを目的とする。   An object of the present invention is to prevent water from entering due to a respiration phenomenon in an injector configured to take out a lead wire from an upper end opening of an injector body.

これによると、シール部材（９）の上端面（９１）、蓋（４）の上端面（４２）、およびボデー（１、３）の上端面（３２）に水が溜まらないため、呼吸現象による水の浸入を防止することができる。   According to this, since water does not accumulate on the upper end surface (91) of the seal member (9), the upper end surface (42) of the lid (4), and the upper end surface (32) of the body (1, 3), Infiltration of water can be prevented.

請求項２に記載の発明のように、請求項１に記載のインジェクタにおいて、シール部材（９）は、ゴムにて成形されたものを用いることができる。また、請求項３に記載の発明のように、請求項１に記載のインジェクタにおいて、シール部材（９）は、リード線（８）と通し孔（４１）との間に充填されたものを用いることができる。   As in the invention described in claim 2, in the injector described in claim 1, the seal member (9) can be formed of rubber. Further, as in the invention according to claim 3, in the injector according to claim 1, the seal member (9) used is filled between the lead wire (8) and the through hole (41). be able to.

請求項４に記載の発明のように、請求項１ないし３のいずれか１つに記載のインジェクタにおいて、蓋（４）とボデー（１、３）との間をＯリング（５）によりシールすることができる。   In the injector according to any one of claims 1 to 3, the gap between the lid (4) and the body (1, 3) is sealed by an O-ring (5). be able to.

本発明の一実施形態について説明する。図１（ａ）は一実施形態に係るインジェクタの正面図、図１（ｂ）は図１（ａ）の平面図、図２は図１のインジェクタの要部を示す正面断面図である。   An embodiment of the present invention will be described. 1A is a front view of an injector according to an embodiment, FIG. 1B is a plan view of FIG. 1A, and FIG. 2 is a front cross-sectional view showing a main part of the injector of FIG.

図１に示すように、インジェクタのロアボデー１には、コモンレール（図示せず）から供給される高圧燃料が流通する高圧通路が形成されており、その高圧燃料は、ロアボデー１の下端に装着されたノズル２からディーゼル内燃機関（図示せず）の気筒内に噴射される。また、このインジェクタは、その軸線が天地方向に略一致する姿勢で内燃機関に搭載される。   As shown in FIG. 1, the lower body 1 of the injector is formed with a high-pressure passage through which high-pressure fuel supplied from a common rail (not shown) flows, and the high-pressure fuel is attached to the lower end of the lower body 1. It is injected from a nozzle 2 into a cylinder of a diesel internal combustion engine (not shown). In addition, the injector is mounted on the internal combustion engine in a posture in which the axis thereof substantially coincides with the vertical direction.

図２に示すように、ロアボデー１の上端外周側には、円筒状のアッパーボデー３が螺合されている。ロアボデー１およびアッパーボデー３は、電磁シールド性に富む金属にて形成されている。なお、ロアボデー１およびアッパーボデー３は、本発明のボデーを構成する。   As shown in FIG. 2, a cylindrical upper body 3 is screwed to the outer periphery of the upper end of the lower body 1. The lower body 1 and the upper body 3 are made of a metal rich in electromagnetic shielding properties. The lower body 1 and the upper body 3 constitute the body of the present invention.

アッパーボデー３の上端には、後述するリード線の取り出し口となる開口部３１が設けられている。この開口部３１に金属または樹脂よりなる円柱状の蓋４が圧入固定されて、開口部３１が塞がれている。この蓋４には、後述するリード線およびシール部材が挿入される貫通した通し孔４１が２つ形成されている。また、アッパーボデー３と蓋４との間にＯリング５が配置されており、アッパーボデー３と蓋４との間はこのＯリング５によりシールされている。   At the upper end of the upper body 3, an opening 31 serving as a lead wire outlet, which will be described later, is provided. A cylindrical lid 4 made of metal or resin is press-fitted and fixed in the opening 31 to close the opening 31. The lid 4 is formed with two through holes 41 through which lead wires and seal members described later are inserted. Further, an O-ring 5 is disposed between the upper body 3 and the lid 4, and the space between the upper body 3 and the lid 4 is sealed by the O-ring 5.

ロアボデー１とアッパーボデー３と蓋４にて囲まれた空間には、高圧通路の燃料圧力を検出する圧力センサ６が配置されている。この圧力センサ６は、ロアボデー１の上端に螺合されている。   In a space surrounded by the lower body 1, the upper body 3 and the lid 4, a pressure sensor 6 for detecting the fuel pressure in the high pressure passage is disposed. The pressure sensor 6 is screwed to the upper end of the lower body 1.

圧力センサ６は、高圧通路の燃料圧力に応じて抵抗値が変化するセンサチップ、センサチップの抵抗値変化に基づいて圧力に応じたセンサ信号を出力する信号処理回路用ＩＣ、および接点６１等を備えている。そして、接点６１がターミナル７に電気的に接続され、さらにターミナル７がリード線８と電気的に接続されている。   The pressure sensor 6 includes a sensor chip whose resistance value changes according to the fuel pressure in the high-pressure passage, a signal processing circuit IC that outputs a sensor signal corresponding to the pressure based on a change in resistance value of the sensor chip, and a contact 61 and the like. I have. The contact 61 is electrically connected to the terminal 7, and the terminal 7 is further electrically connected to the lead wire 8.

リード線８は、蓋４の通し孔４１に挿入され、反ターミナル側が外部に露出している。リード線８と通し孔４１との間はシール部材９によりシールされている。このシール部材９は、ゴムにて円筒状に成形され、内周面にリード線８が密着するとともに、外周面が通し孔４１に密着している。   The lead wire 8 is inserted into the through hole 41 of the lid 4 and the opposite terminal side is exposed to the outside. A space between the lead wire 8 and the through hole 41 is sealed by a seal member 9. The seal member 9 is molded into a cylindrical shape with rubber, and the lead wire 8 is in close contact with the inner peripheral surface, and the outer peripheral surface is in close contact with the through hole 41.

シール部材９は、上端側が通し孔４１から突出しており、シール部材９の上端面９１は蓋４の上端面４２よりも高い位置にある。また、蓋４の上端面４２はアッパーボデー３の上端面３２よりも高い位置にある。なお、これらの上端面３２、４２、９１は、いずれもインジェクタの軸線に対して垂直な平面になっている。   The upper end side of the seal member 9 protrudes from the through hole 41, and the upper end surface 91 of the seal member 9 is located higher than the upper end surface 42 of the lid 4. Further, the upper end surface 42 of the lid 4 is located higher than the upper end surface 32 of the upper body 3. These upper end surfaces 32, 42, 91 are all flat surfaces with respect to the axis of the injector.

このように、シール部材９の上端面９１は蓋４の上端面４２よりも高い位置にあり、また、蓋４の上端面４２はアッパーボデー３の上端面３２よりも高い位置にあるため、図２中に矢印で示すように、シール部材９の上端面９１の水は、重力により蓋４の上端面４２側に落下し、続いてアッパーボデー３の上端面３２側に落下し、さらに、アッパーボデー３の外周面側に落下する。したがって、シール部材９の上端面９１、蓋４の上端面４２、およびアッパーボデー３の上端面３２に水は溜まらない。その結果、リード線８とシール部材９間、シール部材９と通し孔４１間、開口部３１と蓋４間を介して、圧力センサ６の設置空間に水が浸入することを防止することができる。   Thus, the upper end surface 91 of the seal member 9 is at a position higher than the upper end surface 42 of the lid 4, and the upper end surface 42 of the lid 4 is higher than the upper end surface 32 of the upper body 3, 2, the water on the upper end surface 91 of the seal member 9 falls to the upper end surface 42 side of the lid 4 due to gravity, and subsequently falls to the upper end surface 32 side of the upper body 3, and further the upper It falls to the outer peripheral surface side of the body 3. Accordingly, water does not collect on the upper end surface 91 of the seal member 9, the upper end surface 42 of the lid 4, and the upper end surface 32 of the upper body 3. As a result, water can be prevented from entering the installation space of the pressure sensor 6 between the lead wire 8 and the seal member 9, between the seal member 9 and the through hole 41, and between the opening 31 and the lid 4. .

なお、上記実施形態においては、ゴムにて成形されたシール部材９によりリード線８と通し孔４１間をシールしたが、図３に示す変形例のように、リード線８と通し孔４１間に充填材を充填して形成したシール部材９により、リード線８と通し孔４１間をシールしてもよい。なお、その充填材として、接着剤、ホットメルト、樹脂等を用いることができる。   In the above embodiment, the gap between the lead wire 8 and the through hole 41 is sealed with the seal member 9 formed of rubber. However, as in the modification shown in FIG. The space between the lead wire 8 and the through hole 41 may be sealed with a seal member 9 formed by filling the filler. As the filler, an adhesive, hot melt, resin, or the like can be used.

そして、図３に示す変形例においても、シール部材９の上端側を通し孔４１から突出させて、シール部材９の上端面９１を蓋４の上端面４２よりも高くすることにより、シール部材９の上端面９１の水を重力により蓋４の上端面４２側に落下させるようにしている。また、シール部材９の上端面９１を円錐台状にして、シール部材９の上端面９１の水がより落下し易いようにしている。   3, the upper end side of the seal member 9 is protruded from the through hole 41 so that the upper end surface 91 of the seal member 9 is higher than the upper end surface 42 of the lid 4. The water on the upper end surface 91 is dropped to the upper end surface 42 side of the lid 4 by gravity. Further, the upper end surface 91 of the seal member 9 has a truncated cone shape so that the water on the upper end surface 91 of the seal member 9 can be more easily dropped.
