Description

本発明は電線群の止水処理方法、該止水処理方法で止水処理された電線群および該止水処理方法に用いられる巻付用治具に関し、詳しくは、太物電線を含んだ電線群の止水処理を少ない工数で確実に行えるものである。   TECHNICAL FIELD The present invention relates to a water stop treatment method for a wire group, a wire group subjected to a water stop treatment by the water stop treatment method, and a winding jig used in the water stop treatment method. The water stop treatment of the group can be reliably performed with a small number of man-hours.

自動車用のワイヤハーネスは車体のさまざまな箇所に配索されているが、配索箇所に浸水が生じると種々の不具合が発生するため、ワイヤハーネスの配索にあたっては止水性に十分配慮する必要がある。例えば、ワイヤハーネスを車体パネルに設けた貫通孔に貫通して配索する場合には、小径筒部と大径筒部を連通させたゴム製のグロメットにワイヤハーネスを挿通し、該グロメットを前記貫通孔に装着することにより貫通孔の止水を図っている。   Wire harnesses for automobiles are routed at various locations on the vehicle body, but if the routing location is flooded, various problems will occur. is there. For example, when a wire harness is routed through a through-hole provided in a vehicle body panel, the wire harness is inserted into a rubber grommet in which a small diameter cylindrical portion and a large diameter cylindrical portion are communicated, and the grommet is The through hole is water-stopped by being attached to the through hole.

しかし、前記グロメットの小径筒部内にワイヤハーネスを構成する電線群Ｗを集束状態で挿通する場合、電線間や電線と小径筒部の内周面との間に隙間が生じ、これらの隙間から水が浸入するおそれがある。そこで、本出願人は、図６（Ａ）〜（Ｃ）に示すように、止水用のクッション材１の片面接着面１ａ上に電線ｗを所要間隔で１本ずつ平行配置し、クッション材１を寿司巻き状に巻いてグロメット２の小径筒部２ａに圧入する止水構造を提案している［実開平３−１１２９８４号公報（特許文献１）参照］。   However, when the wire group W constituting the wire harness is inserted into the small-diameter cylindrical portion of the grommet in a converged state, a gap is generated between the wires or between the electric wire and the inner peripheral surface of the small-diameter cylindrical portion. May invade. Therefore, as shown in FIGS. 6A to 6C, the present applicant arranges the electric wires w in parallel on the single-sided adhesive surface 1a of the water-stopping cushion material 1 one by one at a required interval, and the cushion material. A water stop structure is proposed in which 1 is wound in a sushi roll and press-fitted into the small-diameter cylindrical portion 2a of the grommet 2 [see Japanese Utility Model Publication No. 3-112984 (Patent Document 1)].

一方、近年では太物電線を混在させた多回路仕様のワイヤハーネスが増加傾向にあり、太物電線の場合、前記特許文献１のように、クッション材の上に１本ずつ平行配置して寿司巻き状に巻き付けても、電線間に隙間が生じてしまい十分な止水性能が得られないという問題がある。そこで、図７に示すように、各太物電線ｗ１〜ｗ６の外周面に防水用のゴムシート４を順に巻き付ける止水構造が採用されているが、この構造では、太物電線ｗ１〜ｗ６の１本ずつにゴムシートを巻き付けていく必要があるため、工数が多く作業性が悪いという問題がある。また、作業者のゴムシート４の巻き付け方によって止水性能にバラつきが生じるという問題もある。   On the other hand, in recent years, the number of wire harnesses with multi-circuit specifications in which thick electric wires are mixed is increasing. In the case of thick electric wires, sushi is arranged in parallel on the cushion material one by one as in Patent Document 1 above. Even if it winds in the shape of a winding, a gap will arise between electric wires and there is a problem that sufficient water stop performance cannot be obtained. Therefore, as shown in FIG. 7, a water stop structure in which the waterproof rubber sheet 4 is wound around the outer peripheral surface of each thick wire w1 to w6 in order is adopted, but in this structure, the thick wire w1 to w6 Since it is necessary to wind rubber sheets one by one, there is a problem that man-hours are large and workability is poor. In addition, there is a problem that the water stop performance varies depending on how the rubber sheet 4 is wound by the operator.

本発明は前記問題に鑑みてなされたものであり、太物電線を含んだ電線群の止水処理を少ない工数で確実に行えることを課題としている。   This invention is made | formed in view of the said problem, and makes it the subject to be able to perform the water stop process of the electric wire group containing a thick electric wire reliably with few man-hours.

前記課題を解決するため、第１の発明として、自動車に配索される電線群の止水処理方法であって、
各１本の電線を挿入する上面開口のＵ溝を並設した巻付用の治具を設け、該治具の上面に防水用ゴムシートの半側部を配置した後に、該防水用ゴムシートの上方から前記各Ｕ溝内に電線を防水用ゴムシートと共に押し込み、ついで、該防水用ゴムシートの他半側部を前記治具の上面に折り返して重ねて、前記各電線を前記防水用ゴムシートにより被覆し、かつ、電線間の前記防水用ゴムシートの半側部と前記防水用ゴムシートの他半側部を隙間なく密着させることを特徴とする電線群の止水処理方法を提供している。 In order to solve the above-mentioned problem, as a first invention, there is a water stop treatment method for a group of wires arranged in an automobile,
A winding jig in which U-grooves in the upper surface opening for inserting each one electric wire are provided side by side, and the waterproof rubber sheet is disposed on the upper surface of the jig, and then the waterproof rubber sheet It said from above pushing the wire with the waterproof rubber sheet in each U groove, then superimposed by folding the other lateral half of the rubber sheet waterproof on the upper surface of the jig, for the waterproof the respective conductive lines coated with a rubber sheet, and a waterproofing method of processing wire group, characterized in that said waterproof rubber sheet lateral half of between wires Ru other lateral half is adhered without a gap of the waterproof rubber sheet providing.

前記のように、各１本の電線を挿入するＵ溝を並設した巻付用治具を用い、該治具上面に配置した防水用ゴムシートの半側部の上方から各電線を該防水用ゴムシートと共に前記Ｕ溝に押し込んだ後、防水用ゴムシートの他半側部を治具上面に折り返す構成としている。これにより、Ｕ溝に押し込まれずに治具上面に残っている防水用シートの半側部と、前記折り返した防水用ゴムシートの他半側部とを平面状に密着させ、Ｕ溝に押し込まれた各電線の外周面全体を防水用ゴムシートで隙間なく被覆することができる。したがって、電線群に太物電線が含まれている場合であっても、電線間に隙間が生じることなく確実に止水される。   As described above, using a winding jig in which U-grooves for inserting each one electric wire are juxtaposed, each electric wire is waterproofed from above the half side portion of the waterproof rubber sheet disposed on the upper surface of the jig. After the rubber sheet is pushed into the U-groove, the other half side portion of the waterproof rubber sheet is folded back to the upper surface of the jig. As a result, the half side portion of the waterproof sheet remaining on the upper surface of the jig without being pushed into the U-groove and the other half side portion of the folded waterproof rubber sheet are brought into close contact with each other in a plane, and pushed into the U groove. Further, the entire outer peripheral surface of each electric wire can be covered with a waterproof rubber sheet without a gap. Therefore, even if a thick wire is included in the wire group, water is reliably stopped without a gap between the wires.

また、前記止水処理方法によれば、巻付用治具上面に配置した防水用ゴムシートと共に各電線を前記Ｕ溝に押し込み、ついで防水用ゴムシートの他半側部を治具上面の防水用ゴムシート半側部に折り返して重ねるだけの簡単な作業で止水処理をほぼ完了させることができるため、工数を低減させ作業性を大幅に向上させることができる。さらに、前記巻付用治具を用いることで作業者による止水性能のバラつきも低減できるため、品質を安定させることができる。   Further, according to the water stop treatment method, each electric wire is pushed into the U-groove together with the waterproof rubber sheet arranged on the upper surface of the winding jig, and the other half side portion of the waterproof rubber sheet is waterproofed on the upper surface of the jig. Since the water stop treatment can be almost completed with a simple operation of folding back and overlapping the rubber sheet half side, the man-hour can be reduced and the workability can be greatly improved. Furthermore, since the variation of the water stop performance by the operator can be reduced by using the winding jig, the quality can be stabilized.

前記各電線を並列状態で前記防水用ゴムシートで連続的に被覆した状態から、円形に丸め、該丸めた状態で弾性部材からなるグロメットの筒部内に挿通していることが好ましい。   It is preferable that the electric wires are rolled in a circular shape from a state in which the electric wires are continuously covered with the waterproof rubber sheet in a parallel state, and inserted in a cylindrical portion of a grommet made of an elastic member in the rounded state.

前記のように、各電線が前記防水用ゴムシートに連続的に被覆された被覆体を円形（ロール状）に丸めることにより、各電線とその外周を被覆する防水用ゴムシートとの密着性を高めることができ、丸めた状態でグロメットの筒部内に挿通することにより止水性能を一層向上させることができる。
前記被覆体を丸める際には、防水用ゴムシートと共に各電線が押し込まれて断面Ｕ字状の凸部が並設された面を内周面とし、その裏面側の平滑面、即ち、折り返された防水用ゴムシートの他半側部により形成された面を外周面として、前記被覆体を丸めていくことが好ましい。丸めた状態での外周面を平滑面としておくことにより、グロメットの筒部内にロール状の被覆体を挿通した際、該ロール状の被覆体とグロメットの筒部との間で及ぼし合う圧力を均一にして、止水性能を高めることができる。 As described above, by rounding a covering body in which each electric wire is continuously covered with the waterproof rubber sheet into a circular shape (roll shape), adhesion between each electric wire and the waterproof rubber sheet covering the outer periphery thereof is improved. The water stop performance can be further improved by inserting the grommets into the cylindrical portion of the grommet in a rolled state.
When the covering body is rolled, the surface on which the electric wires are pushed together with the waterproof rubber sheet and the convex portions having a U-shaped cross section are arranged side by side is used as the inner peripheral surface. It is preferable that the covering is rounded with the surface formed by the other half side portion of the waterproof rubber sheet as the outer peripheral surface. By setting the outer peripheral surface in a rounded state as a smooth surface, when a roll-shaped covering is inserted into the grommet cylinder, the pressure exerted between the roll-shaped covering and the grommet cylinder is uniform. Thus, the water stop performance can be improved.

前記止水処理方法で用いられる防水用ゴムシートとしては、ブチルゴムシートが特に好ましく、巻付用治具の上面に配置したゴムシート上面には粘着層を設けていることが好ましい。
また、グロメットの筒部に挿入される前記ロール状の被覆体は、その外周面を粘着テープでハーフラップ巻きしていることが好ましい。 As the waterproof rubber sheet used in the water stop treatment method, a butyl rubber sheet is particularly preferable, and an adhesive layer is preferably provided on the upper surface of the rubber sheet disposed on the upper surface of the winding jig.
Moreover, it is preferable that the said roll-shaped coating body inserted in the cylinder part of a grommet winds the outer peripheral surface half-wrapping with the adhesive tape.

前記止水処理方法で止水処理された電線群は、前記したように、Ｕ溝に押し込まれずに治具上面に残された防水用シートの半側部と、前記折り返した防水用ゴムシートの他半側部とが平面状に密着され、Ｕ溝に押し込まれた各電線の外周面全体が防水用ゴムシートで隙間なく被覆された状態となるため、電線群に太物電線が含まれている場合であっても、電線間に隙間が生じることなく確実に止水することができる。   As described above, the wire group that has been water-stopped by the water-stop treatment method includes a half side portion of the waterproof sheet that is not pushed into the U-groove and is left on the upper surface of the jig, and the folded waterproof rubber sheet. The other half side is in close contact with the flat surface, and the entire outer peripheral surface of each electric wire pushed into the U-groove is covered with a waterproof rubber sheet without any gaps. Even if it is a case, it can stop reliably, without a clearance gap producing between electric wires.

第３の発明として、前記止水処理方法に用いられる巻付用治具であって、

A winding jig that is to be stacked is provided.

前記のように、防水用ゴムシートの半側部を上面に配置するＵ溝を並設した巻付部と、防水用ゴムシートの他半側部を上面に配置する蓋部とをヒンジ結合して開閉自在としておくことにより、防水用ゴムシートと共に各電線を前記巻付部のＵ溝に押し込んだ後、ヒンジ結合された前記蓋部を巻付部の上面側に回転させるだけで、防水用ゴムシートの他半側部を半側部に容易に重ね合わせることができる。   As described above, the winding portion in which the U-groove for arranging the half side portion of the waterproof rubber sheet on the upper surface and the lid portion for arranging the other half side portion of the waterproof rubber sheet on the upper surface are hingedly connected. By opening and closing freely, each electric wire together with the waterproof rubber sheet is pushed into the U-groove of the winding part, and then the hinge-coupled lid part is rotated to the upper surface side of the winding part. The other half side of the rubber sheet can be easily overlapped with the half side.

前記巻付部に並設するＵ溝は、止水処理する電線群を構成する各電線の線径に対応させた寸法とすることが好ましい。即ち、前記Ｕ溝は、防水性ゴムシートと共に電線を押し込んだ際、該電線の外周面がＵ溝の上面開口から突出しない状態で防水用ゴムシートの他半側部が重ねられるような寸法としておくことが好ましい。これにより、電線径に関わらず、各電線の外周面を防水性ゴムシートで隙間なく被覆することが可能になる。
また、前記各Ｕ溝に各電線を確実に押し込むために、電線と共に押し込まれた防水性ゴムシートがＵ溝の下死点まで到達したことを検知するセンサーを各Ｕ溝の下死点に設けておくことが好ましい。 It is preferable that the U groove provided in parallel with the winding portion has a dimension corresponding to the wire diameter of each electric wire constituting the electric wire group to be water-stopped. That is, the U-groove is dimensioned such that when the electric wire is pushed together with the waterproof rubber sheet, the other half side portion of the waterproof rubber sheet is overlapped in a state where the outer peripheral surface of the electric wire does not protrude from the upper surface opening of the U-groove. It is preferable to keep. Thereby, it becomes possible to coat | cover the outer peripheral surface of each electric wire with a waterproof rubber sheet without a gap irrespective of an electric wire diameter.
In addition, a sensor for detecting that the waterproof rubber sheet pushed together with the electric wire has reached the bottom dead center of the U groove is provided at the bottom dead center of each U groove in order to securely push each electric wire into each U groove. It is preferable to keep it.

前記巻付部を着脱自在に収容する上面開口の収容部と、該収容部の側壁上端から前記蓋部を突設すると共に、対向位置に側壁上端から蓋受部を突設させたベース部材を備えていることが好ましい。   An upper surface opening accommodating portion that detachably accommodates the winding portion, and a base member projecting the lid portion from the upper end of the side wall of the accommodating portion and projecting the lid receiving portion from the upper end of the side wall at an opposing position. It is preferable to provide.

前記のように、巻付部を着脱自在に収容できる収容部を設けておくことにより、止水処理する電線群の各電線径に合わせたＵ溝を備えた巻付部に取り替えるだけで、さまざまな線径の電線からなる電線群の止水処理を、巻付用治具のベース部材は同一のままで行うことができる。
また、蓋部が突設されている前記収容部の側壁と対向する側壁の上端に、該蓋部を受け止める蓋受部を突設しておくことにより、前記蓋部が蓋受部に受け止められる位置まで蓋部を回転させて閉鎖するだけで、該蓋部上面に配置された防水用ゴムシートの他半側部を巻付部上面の半側部に確実に重ね合わせて密着させることができる。前記蓋受部には、蓋部の閉鎖を検知するリミットスイッチを設けておくことが好ましい。 As described above, by providing an accommodating part that can detachably accommodate the winding part, simply replacing it with a winding part provided with a U-groove that matches the diameter of each wire of the wire group to be water-stopped. The water stopping treatment of the electric wire group composed of the electric wires having the appropriate wire diameter can be performed while the base member of the winding jig remains the same.
Moreover, the lid part is received by the lid receiving part by projecting a lid receiving part for receiving the lid part at the upper end of the side wall opposite to the side wall of the housing part from which the lid part is projected. By simply rotating and closing the lid portion to the position, the other half side portion of the waterproof rubber sheet disposed on the upper surface of the lid portion can be securely overlapped and adhered to the half side portion of the upper surface of the winding portion. . It is preferable that a limit switch for detecting closing of the lid portion is provided in the lid receiving portion.

前述したように、各１本の電線を挿入するＵ溝を並設した巻付用治具を用い、該治具上面に配置した防水用ゴムシートの半側部の上方より各電線を前記防水用ゴムシートと共に前記Ｕ溝に押し込み、ついで防水用ゴムシートの他半側部を治具上面に折り返す構成とすることにより、Ｕ溝に押し込まれずに治具上面に残されている防水用シートの半側部と、前記折り返した防水用ゴムシートの他半側部とを治具上面で平面状に密着させ、Ｕ溝に押し込まれた各電線の外周面全体を防水用ゴムシートで隙間なく被覆することができる。したがって、電線群に太物電線が含まれている場合であっても、前記止水処理方法で処理された電線群は電線間に隙間が生じることなく確実に止水される。   As described above, using a winding jig in which U-grooves for inserting each one electric wire are juxtaposed, each electric wire is waterproofed from above the half side portion of the waterproof rubber sheet disposed on the upper surface of the jig. Of the waterproof sheet remaining on the upper surface of the jig without being pushed into the U groove by being pushed into the U groove together with the rubber sheet and then folding back the other half of the waterproof rubber sheet to the upper surface of the jig. The half-side portion and the other half-side portion of the folded waterproof rubber sheet are brought into close contact with each other on the upper surface of the jig, and the entire outer peripheral surface of each electric wire pushed into the U-groove is covered with the waterproof rubber sheet without any gap. can do. Therefore, even when a thick wire is included in the wire group, the wire group treated by the water stop treatment method is surely stopped without a gap between the wires.

また、前記止水処理方法によれば、巻付用治具上面に配置した防水用ゴムシートと共に各電線を前記Ｕ溝に押し込み、ついで防水用ゴムシートの他半側部を治具上面の防水用ゴムシート半側部に折り返して重ねるだけの簡単な作業で止水処理をほぼ完了させることができるため、工数を低減させ作業性を大幅に向上させることができる。さらに、前記巻付用治具を用いることで作業者による止水性能のバラつきを低減でき、品質を安定させることができる。   Further, according to the water stop treatment method, each electric wire is pushed into the U-groove together with the waterproof rubber sheet arranged on the upper surface of the winding jig, and the other half side portion of the waterproof rubber sheet is waterproofed on the upper surface of the jig. Since the water stop treatment can be almost completed with a simple operation of folding back and overlapping the rubber sheet half side, the man-hour can be reduced and the workability can be greatly improved. Furthermore, the use of the winding jig can reduce variations in the water stop performance by the operator, and can stabilize the quality.

In the present embodiment, a butyl rubber sheet is used as the waterproof rubber sheet 20 and an adhesive layer (not shown) is provided on the upper surface of the arranged butyl rubber sheet.
The electric wires w1 to w5 are pushed into the U grooves 11a to 11e together with the waterproof rubber sheet 20a from above the half side portion 20a of the waterproof rubber sheet 20 arranged. At this time, it is possible to confirm that each of the electric wires w1 to w5 is surely pushed together with the waterproof rubber sheet 20a by lighting each display portion 17.

電線ｗ１〜ｗ５の押し込み後、図２（Ｂ）に示すように蓋部１５を閉鎖する。即ち、蓋部１５を巻付部１１上面側に回転させて蓋受部１６に蓋部１５が受け止められ、蓋受部１６のリミットスイッチ１８がＯＮになることによって、蓋部１５の閉鎖が確認できる。蓋部１５の閉鎖によって、蓋部１５上面に配置された防水用ゴムシート２０の他半側部２０ｂが巻付部１１上面に配置された防水用ゴムシート２０の半側部２０ａに重ねられ、密着される。
この後、蓋部１５を開き、電線ｗ１〜ｗ５が並列状態で防水用ゴムシート２０に連続的に被覆された被覆体２１を取り出す［図２（Ｃ）］。 After the electric wires w1 to w5 are pushed in, the lid portion 15 is closed as shown in FIG. That is, the lid 15 is rotated to the upper surface side of the winding part 11 so that the lid 15 is received by the lid receiver 16 and the limit switch 18 of the lid receiver 16 is turned on, thereby confirming that the lid 15 is closed. it can. By closing the lid portion 15, the other half side portion 20 b of the waterproof rubber sheet 20 disposed on the top surface of the lid portion 15 is overlapped with the half side portion 20 a of the waterproof rubber sheet 20 disposed on the top surface of the winding portion 11. Close contact.
Then, the cover part 15 is opened, and the covering body 21 continuously covered with the waterproof rubber sheet 20 in the state where the wires w1 to w5 are in parallel is taken out [FIG. 2 (C)].

取り出した被覆体２１の凸部が並列した面２１ａを内周面とし、裏面側の平滑面２１ｂを外周面として、被覆体２１をロール状に丸め(図３)、その外周面に粘着テープ２２をハーフラップで隙間なく巻き付ける（図４）。ついで、テープ巻きしたロール状の被覆体２３を、グロメット３０の小径筒部３１に挿通して、電線群Wの止水処理が完了する（図５）。   The coated body 21 is rolled into a roll shape with the surface 21a on which the convex portions of the taken-out coated body 21 are arranged in parallel as the inner peripheral surface and the smooth surface 21b on the back side as the outer peripheral surface (FIG. 3). Is wrapped with a half wrap without gaps (FIG. 4). Next, the roll-shaped covering body 23 wound with tape is inserted into the small diameter cylindrical portion 31 of the grommet 30 to complete the water stop treatment of the electric wire group W (FIG. 5).

前記のように、Ｕ溝１１ａ〜１１ｅを並設した巻付部１１を収容した巻付用治具１０を用い、巻付部１１上面に配置した防水用ゴムシート２０の半側部２０ａの上方から、各電線ｗ１〜ｗ５を防水用ゴムシート２０ａと共にＵ溝１１ａ〜１１ｅに押し込んだ後、防水用ゴムシート２０の他半側部２０ｂが上面に配置された蓋部１５を回転させて、該防水用ゴムシート２０の他半側部２０ｂを巻付部１１上面に折り返す構成としている。これにより、Ｕ溝１１ａ〜１１ｅに押し込まれずに巻付部１１上面に残っている防水用シート２０の半側部と、折り返した他半側部２０ａとを平面状に密着させ、Ｕ溝１１ａ〜１１ｅに押し込まれた各電線ｗ１〜ｗ５の外周面全体を防水用ゴムシート２０で隙間なく被覆することができる。したがって、電線群Ｗに太物電線ｗ１〜ｗ４が含まれている場合であっても、電線間に隙間が生じることなく確実に止水される。   As described above, the winding jig 10 containing the winding portion 11 in which the U grooves 11a to 11e are arranged side by side is used, and the upper side of the half side portion 20a of the waterproof rubber sheet 20 disposed on the upper surface of the winding portion 11 is used. Then, after each of the electric wires w1 to w5 is pushed into the U grooves 11a to 11e together with the waterproof rubber sheet 20a, the lid portion 15 on which the other half side portion 20b of the waterproof rubber sheet 20 is arranged on the upper surface is rotated, The other half side portion 20 b of the waterproof rubber sheet 20 is folded back to the upper surface of the winding portion 11. Thereby, the half side part of the waterproof sheet 20 remaining on the upper surface of the winding part 11 without being pushed into the U grooves 11a to 11e and the other half side part 20a folded back are brought into close contact with each other in a planar manner, and the U grooves 11a to 11a The entire outer peripheral surface of each of the electric wires w1 to w5 pushed into 11e can be covered with the waterproof rubber sheet 20 without a gap. Therefore, even if it is a case where the thick wire w1-w4 is contained in the electric wire group W, water is reliably stopped, without a clearance gap producing between electric wires.

また、巻付部１１上面に配置した防水用ゴムシート２０ａと共に各電線ｗ１〜ｗ５をＵ溝１１ａ〜１１ｅに押し込み、ついで蓋部１５上面に配置した防水用ゴムシート２０の他半側部２０ｂを巻付部１１上面の半側部２０ａに折り返して重ねる簡単な作業で止水処理をほぼ完了させることができるため、工数を低減させ作業性を大幅に向上させることができる。さらに、巻付用治具１０を用いることで作業者による止水性能のバラつきも低減できるため、品質を安定させることができる。   Further, the electric wires w1 to w5 are pushed into the U grooves 11a to 11e together with the waterproof rubber sheet 20a disposed on the upper surface of the winding portion 11, and then the other half side portion 20b of the waterproof rubber sheet 20 disposed on the upper surface of the lid portion 15 is provided. Since the water-stopping treatment can be almost completed by a simple operation of folding back and overlapping the half side portion 20a on the upper surface of the winding portion 11, man-hours can be reduced and workability can be greatly improved. Furthermore, since the variation in the water stop performance by the operator can be reduced by using the winding jig 10, the quality can be stabilized.
