Description

本発明は、車載用制御装置に関し、特に、装置の筐体から蓋体が離脱する不具合を防止させる際に用いて好適のものである。 The present invention relates to a vehicle-mounted control device, and is particularly suitable for use in preventing a problem that a lid body is detached from a housing of the device.

近年、自動車には、モータ等の電気的制御を受ける装置が種々搭載されており、かかる車載装置は、ＥＣＵ（Electric
Control Unit）等の制御装置が設けられ、かかる制御装置（以下、車載用制御装置）によって所望の制御動作が行われる。 2. Description of the Related Art In recent years, automobiles are equipped with various devices that receive electrical control, such as motors.
A control device such as a control unit is provided, and a desired control operation is performed by the control device (hereinafter referred to as an in-vehicle control device).

図６は、かかる種々の車載用制御装置のうち、ＢＣＭ（Body Control Module）と呼ばれる車載用制御装置の一例が示されている。かかる車載用制御装置５は、図示の如く、ブラケット１と筐体３と蓋体４と図示されない制御基板とから構成されている。ブラケット１は、筐体３の側壁に固定されると供に、自動車のＡピラー及びフロントタイヤハウジングの合流点近傍のパネル（以下、ダッシュサイドパネルと呼ぶ）に固定される。筐体３は、側面３ｂ〜３ｃ及び底面３ｅから成り、先のブラケット１を固定させる支持部３ａ〜３ｄと、ソケット支持部３ａと、矩形状の穴が形成された凹状部３ｆとが、これらの面に形成されている。また、筐体３の内部空間には、図示されない制御基板が収容されている。また、蓋部４は、ソケット４ａ〜４ｂを有し、更に、複数の凸状部４ｃを備えている。そして、図７に示す如く、蓋体４を筐体の挿入方向Ｙへ嵌挿させることにより、当該蓋体４は、凹状体３ｆに凸状体４ｃが到達すると、側壁３ｂに圧縮された凸状体４ｃが鉛直方向Ｚに開放され、筐体３にロックされることとなる。 FIG. 6 shows an example of an in-vehicle control device called a BCM (Body Control Module) among the various in-vehicle control devices. As shown in the figure, the in-vehicle control device 5 includes a bracket 1, a housing 3, a lid 4, and a control board (not shown). The bracket 1 is fixed to the side wall of the housing 3 and is also fixed to a panel (hereinafter referred to as a dash side panel) in the vicinity of the junction of the A pillar of the automobile and the front tire housing. The housing 3 includes side surfaces 3b to 3c and a bottom surface 3e, and includes support portions 3a to 3d for fixing the bracket 1, a socket support portion 3a, and a concave portion 3f in which a rectangular hole is formed. It is formed on the surface. A control board (not shown) is accommodated in the internal space of the housing 3. The lid 4 has sockets 4a to 4b and further includes a plurality of convex portions 4c. Then, as shown in FIG. 7, when the cover 4 is fitted in the insertion direction Y of the housing, the cover 4 is projected onto the concave 3 f when the convex 4 c reaches the concave 3 f. The body 4c is opened in the vertical direction Z and locked to the housing 3.

しかしながら、かかる車載用制御装置５は、振動の伝わり易い車体パネルに固定されるため、自動車が走行している間、常に変形を繰り返すこととされる。具体的に説明すると、振動の或る場面では、図７（ａ）に示す如く、装置の鉛直方向のＺ２側で圧縮力が働き且つＺ１側で伸長力が働く際、筐体３の側面３ｂは、鉛直方向のＺ２側で撓みを起こす。一方、図７（ｂ）に示す如く、装置の鉛直方向のＺ１側で圧縮力が働き且つＺ２側で伸長力が働く際、筐体３の側面３ｂは、鉛直方向のＺ１側で撓みを起こす。そして、かかる動作は、ダッシュサイドパネルの振動周波数と同期して繰返される。 However, since the vehicle-mounted control device 5 is fixed to the vehicle body panel that easily transmits vibrations, the vehicle-mounted control device 5 always repeats deformation while the automobile is running. More specifically, in a certain scene of vibration, as shown in FIG. 7A, when the compressive force is applied on the Z2 side in the vertical direction of the apparatus and the extension force is applied on the Z1 side, the side surface 3b of the housing 3 is used. Causes bending on the Z2 side in the vertical direction. On the other hand, as shown in FIG. 7B, when a compressive force is applied on the Z1 side in the vertical direction of the apparatus and an extension force is applied on the Z2 side, the side surface 3b of the housing 3 is bent on the Z1 side in the vertical direction. . Such an operation is repeated in synchronization with the vibration frequency of the dash side panel.

かかる場合、図８に示す如く、凸状体４ｃ及び凹状体３ｆの当接面はＺ軸方向と略平行な関係を有しているため、筐体３の側壁３ｂがＺ方向へ変形を繰返すと、変形の大きさ如何によっては凸状体４ｃと凹状体３ｆとの嵌合が解け、蓋体４は、筐体３から離脱してしまうとの問題が生じる。かかる場合、内蔵される車載用制御基板は、各種コネクタとの結合が解除されるとの問題、又は、当該車載用制御基板が筐体３から離脱し落下してしまうとの問題も起こり得る。 In this case, as shown in FIG. 8, since the contact surfaces of the convex body 4c and the concave body 3f have a substantially parallel relationship with the Z-axis direction, the side wall 3b of the housing 3 is repeatedly deformed in the Z direction. Then, depending on the size of the deformation, the fitting of the convex body 4c and the concave body 3f is released, and there arises a problem that the lid body 4 is detached from the housing 3. In such a case, there may be a problem that the built-in vehicle-mounted control board is uncoupled from various connectors, or that the vehicle-mounted control board is detached from the housing 3 and dropped.

また、ダッシュサイドパネル又は車載用制御装置５に熱膨張が発生すると、当該車載用制御装置５には、図７（ａ）又は図７（ｂ）に示される力が静的に加わるため、これによっても、蓋体４は、筐体３から離脱してしまうとの上述同様の問題が生じる。 Further, when thermal expansion occurs in the dash side panel or the vehicle-mounted control device 5, the force shown in FIG. 7 (a) or FIG. 7 (b) is applied to the vehicle-mounted control device 5 statically. This also causes the same problem as described above that the lid 4 is detached from the housing 3.

そこで、かかる問題を回避すべく、特開２００５−１６０２０７号公報（特許文献１）では、ケース（特許請求の範囲における筐体）の構造を改変させた電子ユニット（特許請求の範囲における車載用制御装置）が紹介されている。かかる電子ユニットは、係止爪を具備するユニット本体（特許請求の範囲における車載用制御基板）と、当該ユニット本体を収容させ且つ係止孔を具備するケースと、ユニット本体のコネクタ嵌合部に形成された係合溝と、ケースに一体的に形成され当該係合溝に挿入される係止リブとを備えている。かかる電子ユニットは、ケースとユニット本体とを組み立てる際、係止爪と係止孔とを係合させて双方を固定させ、且つ、係止リブを係合溝に挿入させることでケースの変形を阻止し、これにより、振動が生じていても、係止爪と係止孔との係合状態を維持させるものとしている。 In order to avoid such a problem, Japanese Patent Laid-Open No. 2005-160207 (Patent Document 1) discloses an electronic unit (in-vehicle control in the claims) in which the structure of the case (the casing in the claims) is modified. Device). Such an electronic unit includes a unit main body (a vehicle-mounted control board in claims) having a locking claw, a case for housing the unit main body and having a locking hole, and a connector fitting portion of the unit main body. An engagement groove formed and a locking rib formed integrally with the case and inserted into the engagement groove are provided. When assembling the case and the unit main body, the electronic unit is configured so that the locking claw and the locking hole are engaged to fix both, and the locking rib is inserted into the engaging groove to deform the case. This prevents the engagement state between the engagement claw and the engagement hole even if vibration is generated.

また、特開昭５７−０７３３６５号公報（特許文献２）には、エンジンルームに搭載されるエアクリーナが紹介されている。かかるエアクリーナは、エアクリーナを収容させるケースと、当該ケースの開口部を閉塞させるキャップと、キャップに一体形成されたフックと、ケースの側面から突出するように形成された突起上のフック引掛け部とから構成される。そして、かかるフック及びフック引掛け部は、互いの当接面がキャップの取付方向に対して一定の傾斜角を有しており、キャップとケースとの嵌着力を強化させている。 Japanese Patent Laid-Open No. 57-073365 (Patent Document 2) introduces an air cleaner mounted in an engine room. Such an air cleaner includes a case for accommodating the air cleaner, a cap for closing the opening of the case, a hook formed integrally with the cap, and a hook hooking portion on a protrusion formed so as to protrude from the side surface of the case. Consists of The hooks and hook hooks have contact surfaces with each other that have a certain inclination angle with respect to the direction in which the cap is attached, thereby strengthening the fitting force between the cap and the case.

しかしながら、特許文献１に係る技術では、コネクタ嵌合部に係合溝を形成させ且つケースにも係止リブを形成させるため、装置の構造上の複雑化を招くとの問題が生じる。かかる問題は、金型の複雑化又は加工工程の新たな追加を伴うので、コストの高騰に繋がるとの問題も有する。 However, in the technique according to Patent Document 1, since the engaging groove is formed in the connector fitting portion and the locking rib is also formed in the case, there arises a problem that the structure of the apparatus is complicated. Such a problem involves a complicated mold or a new process step, which leads to a cost increase.

また、特許文献２に係る技術では、フックとフック引掛け部との間にスペースが形成されるので、フックの自由な変形を許容させ、フックとフック引掛け部との係合が解かれ易くなるとの問題が生じる。また、フック引掛け部は、ケースの側壁から突出した状態にて形成されるので、当該フック引掛け部を具備するケースでは、構造の複雑化、フック引掛け部の破損の多発、高コスト化を招くとの問題が生じる。 In the technology according to Patent Document 2, since a space is formed between the hook and the hook hooking portion, the hook is allowed to be freely deformed, and the hook and the hook hooking portion are easily disengaged. The problem arises. In addition, since the hook hook portion is formed in a state protruding from the side wall of the case, in the case having the hook hook portion, the structure is complicated, the hook hook portion is frequently damaged, and the cost is increased. Cause the problem of inviting.

筐体３０は、上述の如く、車載用制御基板２０を挿入させる開口部３１を有する。また、筐体３０は、開口部３１の短手方向の辺を含む第１の側面３４ａ，３４ｂと、開口部３１の長手方向の辺を含む第２の側面３５ａ，３５ｂと、底面３６とによって内部空間が形成され、基板レール３４ｄに沿って車載用制御基板２０を内部空間Ａへ収容させる。また、第２の側面３５ａ，３５ｂには、複数の凹状部３７と長手側リブ３８とが形成され、第１の側面３４ａ，３４ｂには、ブラケット受け３４ｃと短手側リブ３９とが形成され、底面３６には、ソケット受け３６ａ，３６ｂが各々一体的に形成されている。かかる筐体３０は、ＡＢＳ(Acrylonitrile Butadiene Styrene) 、又は、ＰＢＴ（Polybutylene Terephthalate）等の樹脂材料から成形される。 As described above, the housing 30 has the opening 31 into which the in-vehicle control board 20 is inserted. In addition, the housing 30 includes first side surfaces 34 a and 34 b that include sides in the short direction of the opening 31, second side surfaces 35 a and 35 b that include sides in the longitudinal direction of the opening 31, and a bottom surface 36. An internal space is formed, and the vehicle-mounted control board 20 is accommodated in the internal space A along the board rail 34d. A plurality of concave portions 37 and long side ribs 38 are formed on the second side surfaces 35a and 35b, and a bracket receiver 34c and a short side rib 39 are formed on the first side surfaces 34a and 34b. The socket receivers 36a and 36b are integrally formed on the bottom surface 36, respectively. The housing 30 is molded from a resin material such as ABS (Acrylonitrile Butadiene Styrene) or PBT (Polybutylene Terephthalate).

蓋体４０は、上述同様の樹脂材料から成り、内部空間側から第２の側面３５ａ，３５ｂに当接する長手当接面４３を有し、当該長手当接面４３には、複数の凸状部４３が一体的に形成されている。蓋体４０は、図２に示す如く、筐体３０に装着されることにより、開口部３１を閉塞させる。かかる蓋体４０は、更に正面へ板状体４１を備え、当該板状体４１には、ソケット受け４２ａ，４２ｂが開口されている。 The lid body 40 is made of the same resin material as described above, and has a longitudinal contact surface 43 that contacts the second side surfaces 35a and 35b from the inner space side. The longitudinal contact surface 43 includes a plurality of convex portions. 43 is integrally formed. As shown in FIG. 2, the lid 40 is attached to the housing 30 to close the opening 31. The lid body 40 further includes a plate-like body 41 on the front surface, and socket receivers 42 a and 42 b are opened in the plate-like body 41.

図３は、図２におけるＡ−Ａ断面を矢線方向に観察した状態が示されている。図３（ｂ）に示す如く、蓋体４０に形成され凸状部４４ｃは、当該凸状部に形成された凸状部側嵌合面Ｓｆ１が蓋体４０の分解方向Ｘへ傾倒されている。また、図３（ｃ）に示す如く、筐体３０に形成され凹状部３７は、凸状部４４ｃの嵌合面Ｓｆ１に対して略平行な凹状部側嵌合面Ｓｆ２を有している。 FIG. 3 shows a state where the AA cross section in FIG. 2 is observed in the direction of the arrow. As shown in FIG. 3 (b), the convex portion 44 c formed on the lid body 40 is inclined such that the convex portion-side fitting surface Sf 1 formed on the convex portion is in the disassembly direction X of the lid body 40. . Further, as shown in FIG. 3C, the concave portion 37 formed on the housing 30 has a concave portion side fitting surface Sf2 substantially parallel to the fitting surface Sf1 of the convex portion 44c.

そして、本実施の形態に係る蓋体４０を筐体３０に組付けると、図３（ａ）に示す如く、凸状部４４ｃと凹状部３７との当接面は、鉛直方向よりも分解方向Ｘへ角度θ傾倒した状態とされる。尚、凸状部４４ｃと凹状部３７とは、図示されていないが、図３（ａ）における第２の側面３５ｂにも形成されている。 When the lid 40 according to the present embodiment is assembled to the housing 30, the contact surface between the convex portion 44c and the concave portion 37 is disassembled more than the vertical direction as shown in FIG. The angle θ is inclined to X. In addition, although the convex-shaped part 44c and the concave-shaped part 37 are not shown in figure, they are also formed in the 2nd side surface 35b in Fig.3 (a).

かかる蓋体４０及び筐体３０による構造は、凸状部が凹状部に係合されると、筐体４０及び蓋体４０とを互いに固定させる嵌着機能を発揮させる。また、筐体３０の第２の側面３５ａは、かかる構造に振動又は熱応力等の力が加わると、傾倒した当接面によって第２の側面３５ａのＺ１方向の逆方向へ当該力の成分が与えられるので、かかる構造では、筐体３０及び蓋体４０との係合状態の解除を阻止させる離脱阻止機能を発揮させる。 Such a structure of the lid 40 and the housing 30 exhibits a fitting function for fixing the housing 40 and the lid 40 to each other when the convex portion is engaged with the concave portion. In addition, when a force such as vibration or thermal stress is applied to the structure on the second side surface 35a of the housing 30, the component of the force is applied in the direction opposite to the Z1 direction of the second side surface 35a by the inclined contact surface. Therefore, in such a structure, the separation preventing function that prevents the engagement state between the housing 30 and the lid body 40 from being released is exhibited.

図４は、図２における車載用制御装置をＢ−Ｂ矢視方向に観察した状態が示されている。同図を参照すると、第１の側面３４ａ，３４ｂに板厚ｔ２の短手側リブ３９が一体的に形成されているのが観察できる。また、第２の側面３５ａ，３５ｂに板厚ｔ１の長手側リブ３８が一体的に形成されているのが観察できる。そして、第２の側面３５ａ，３５ｂの長手側リブ３８は、第１の側面３４ａ，３４ｂの短手側リブ３９より厚く成形されている。 FIG. 4 shows a state in which the in-vehicle control device in FIG. 2 is observed in the direction of arrows BB. Referring to the figure, it can be observed that the short side ribs 39 having the plate thickness t2 are integrally formed on the first side surfaces 34a and 34b. Further, it can be observed that the longitudinal ribs 38 having a thickness t1 are integrally formed on the second side surfaces 35a and 35b. The long side ribs 38 of the second side surfaces 35a and 35b are formed thicker than the short side ribs 39 of the first side surfaces 34a and 34b.

かかる筐体３０の開口部３１では、双方のリブ３８，３９によって、開口部３１の中心回りの断面係数が補われ、撓みの発生が抑制される。また、第２の側面３５ａ，３５ｂの長手側リブ３８は、第１の側面３４ａ，３４ｂの短手側リブ３８より厚く設定されるので、かかる撓みの抑制効果をより顕著に発揮させる。更に、第１の側面３４ａ，３４ｂの短手側リブ３９は、第２の側面３５ａ，３５ｂの長手側リブ３９より薄く設定されるので、所定範囲内の変形を許容させ、長手方向のモーメントを減少させ、これにより第２の側面３５ａ，３５ｂにおける撓みの低減効果を発揮させる。 In the opening 31 of the housing 30, the ribs 38 and 39 supplement the section modulus around the center of the opening 31 and suppress the occurrence of bending. Further, since the long side ribs 38 of the second side surfaces 35a and 35b are set to be thicker than the short side ribs 38 of the first side surfaces 34a and 34b, the effect of suppressing such bending is more remarkably exhibited. Further, since the short side ribs 39 of the first side surfaces 34a and 34b are set thinner than the long side ribs 39 of the second side surfaces 35a and 35b, deformation within a predetermined range is allowed and a moment in the longitudinal direction is set. This reduces the bending of the second side surfaces 35a and 35b.

図５は、本実施の形態に係る車載用制御装置がダッシュサイドパネルＰｎｌに固定された状態が示されている。図５（ａ）は、装置の鉛直方向のＺ２側で圧縮力が働き且つＺ１側で伸長力が働く場面が示されている。かかる場合、当接面が分解方向Ｘへ傾倒する嵌合構造を備えているので、筐体３０及び蓋体４０との係合状態の解除を阻止させる離脱阻止機能が働き、第２の側面３５ｂをＺ１方向に引き付ける力Ｆ１が働く。これにより、車載用制御装置１００では、第２の側面３５ｂに撓みが生じないので、筐体３０から蓋体４０が離脱することはい。 FIG. 5 shows a state where the in-vehicle control device according to the present embodiment is fixed to the dash side panel Pnl. FIG. 5A shows a scene in which a compressive force acts on the Z2 side in the vertical direction of the apparatus and an extension force acts on the Z1 side. In such a case, since the contact surface is provided with a fitting structure that tilts in the disassembly direction X, a separation preventing function that prevents the engagement state between the housing 30 and the lid 40 from being released works, and the second side surface 35b. A force F1 that attracts Z in the Z1 direction works. Thereby, in the vehicle-mounted control apparatus 100, since the 2nd side surface 35b does not bend, the cover body 40 does not detach | leave from the housing | casing 30.

また、図５（ｂ）には、装置の鉛直方向のＺ１側で圧縮力が働き且つＺ２側で伸長力が働く場面が示されている。かかる場合にあっても、当接面が分解方向Ｘへ傾倒する嵌合構造を備えているので、筐体３０及び蓋体４０との係合状態の解除を阻止させる離脱阻止機能が働き、第２の側面３５ａをＺ２方向に引き付ける力Ｆ２が働く。これにより、車載用制御装置１００では、第２の側面３５ａに撓みが生じないので、筐体３０から蓋体４０が離脱することはい。 Further, FIG. 5B shows a scene in which a compressive force works on the Z1 side in the vertical direction of the apparatus and an extension force works on the Z2 side. Even in such a case, since the contact surface is provided with a fitting structure that tilts in the disassembling direction X, the separation preventing function that prevents the engagement state between the housing 30 and the lid body 40 from functioning works. A force F2 that attracts the side surface 35a of the second member in the Z2 direction is applied. Thereby, in the vehicle-mounted control apparatus 100, since the bending is not produced in the 2nd side surface 35a, the cover body 40 does not detach | leave from the housing | casing 30.

また、図５（ａ）及び図５（ｂ）の何れの場合にあっても、振動又は熱応力によって生じた応力は、第１の側面３４ａ，３４ｂにて適宜に開放されるので、本実施の形態に係る車載用制御装置１００では、長手方向のモーメントを減少させ、これにより第２の側面３５ａ，３５ｂにおける撓みを低減させる。 Further, in either case of FIGS. 5A and 5B, the stress generated by vibration or thermal stress is appropriately released at the first side surfaces 34a and 34b. In the vehicle-mounted control device 100 according to the embodiment, the moment in the longitudinal direction is reduced, thereby reducing the bending at the second side surfaces 35a and 35b.

上述の如く、本実施の形態に係る車載用制御装置１００によると、凸状部４４ｃ及び凹状部３７の係合によって、筐体３０及び蓋体４０とを互いに固定させる嵌着機能と、筐体３０及び蓋体４０との係合状態の解除を阻止させる離脱阻止機能との双方の機能を与え、且つ、筐体の開口部に２種類の厚さのリブを形成させることにより、筐体の撓みを抑制できるので、簡素な構成で蓋体の更なる離脱阻止機能が実現される。また、筐体３０及び蓋体４０は、上述の如く開口部での強度が補強されるので、自動車のような高温且つ振動環境下であっても、使用する樹脂製品の材質に関わり無く、長期間に亘って嵌合状態を好適に維持させることが可能となる。 As described above, according to the vehicle-mounted control device 100 according to the present embodiment, the fitting function for fixing the housing 30 and the lid body 40 to each other by the engagement of the convex portion 44c and the concave portion 37, and the housing 30 and the disengagement prevention function for preventing the release of the engaged state with the lid body 40, and by forming ribs of two types of thickness in the opening of the housing, Since bending can be suppressed, a further detachment prevention function of the lid can be realized with a simple configuration. In addition, since the strength at the opening is reinforced as described above, the housing 30 and the lid 40 are long regardless of the material of the resin product to be used, even under a high temperature and vibration environment such as an automobile. It becomes possible to maintain a fitting state suitably over a period.

尚、上述した実施の形態は、特許請求の範囲に記載される発明の一例に過ぎず、特許請求の範囲に記載される発明は、かかる実施の形態に限定されるものでは無い。上述した車載用制御装置１００では、凸状部及び凹状部と、長手側リブ及短手側リブとの双方の特徴部を具備している。しかし、これに限らず、他の形態の発明として、長手側リブ及短手側リブの構成を排除したとしても、かかる車載用制御装置１００では、凸状部及び凹状部の係合によって、筐体及び蓋体とを互いに固定させる嵌着機能と、筐体及び蓋体との係合状態の解除を阻止させる離脱阻止機能との双方の機能を具備しているので、複雑な構成を追加させることなく、簡素な構成で蓋体の更なる離脱阻止機能が実現される。 The embodiment described above is merely an example of the invention described in the claims, and the invention described in the claims is not limited to the embodiments. The on-vehicle control device 100 described above includes both the convex and concave portions and the characteristic portions of the long side rib and the short side rib. However, the present invention is not limited to this, and as another aspect of the invention, even if the configuration of the long side rib and the short side rib is eliminated, the in-vehicle control device 100 is configured to engage with the convex portion and the concave portion. Since it has both a fitting function for fixing the body and the lid to each other and a detachment prevention function for preventing the engagement state between the housing and the lid from being released, a complicated configuration is added. Without this, a further function of preventing the lid from being detached is realized with a simple configuration.

また、他の形態の発明として、実施の形態における凸状部及び凹状部の構成を排除させたとしても、かかる車載用制御装置１００では、凸状部及び凹状部の係合によって、筐体及び蓋体とを互いに固定させる嵌着機能と、筐体及び蓋体との係合状態の解除を阻止させる離脱阻止機能との双方の機能を具備しているので、複雑な構成を追加させることなく、簡素な構成で蓋体の更なる離脱阻止機能が実現される。 Further, as another aspect of the invention, even if the configuration of the convex portion and the concave portion in the embodiment is eliminated, in the in-vehicle control device 100, the casing and the concave portion are engaged by the engagement of the convex portion and the concave portion. Since it has both functions of a fitting function for fixing the lid to each other and a detachment prevention function for preventing the release of the engagement state between the housing and the lid, without adding a complicated configuration Further, the function of preventing further detachment of the lid body is realized with a simple configuration.

更に、他の形態の発明として、蓋体４０に凹状部を形成させ、且つ、筐体３０に凸状部を形成させることとしても、双方の当接面が分解方向Ｘへ傾倒しているのであれば、上述した作用効果が損なわれるものでないことは言うまでもない。 Furthermore, as another aspect of the invention, even when the concave portion is formed on the lid 40 and the convex portion is formed on the housing 30, both contact surfaces are inclined in the disassembly direction X. Needless to say, the above-described operational effects are not impaired.
