Description

この発明は、例えば自動車などの車両に搭載される電気接続箱の取り付け構造に関し、より詳しくはガタつきのない取り付け状態が得られるような取り付け構造に関する。 The present invention relates to an attachment structure for an electric junction box mounted on a vehicle such as an automobile, and more particularly to an attachment structure that can provide an attachment state without rattling.

電気接続箱を車両に取り付けるために、車両に設けられる金属製のステーと、電気接続箱に形成されてステーの差し込み片が差し込まれるブラケットが利用されている。 In order to attach the electrical junction box to the vehicle, a metal stay provided in the vehicle and a bracket formed in the electrical junction box and into which the stay insertion piece is inserted are used.

下記特許文献１に開示されているように、ステーの差し込み片は平板状であり、差し込み片の中央には貫通穴状の四角い係止部が形成されている。他方、ブラケットは合成樹脂製で、差し込み片の左右両側縁を受け入れて保持するとともに、差し込み片の係止部に係止する弾性変位可能で先端面が係止部に係止する係止爪を有している。 As disclosed in Patent Document 1 below, the stay insertion piece has a flat plate shape, and a square locking portion having a through-hole shape is formed at the center of the insertion piece. On the other hand, the bracket is made of synthetic resin, and receives and holds the left and right side edges of the insertion piece, and has a locking claw that can be elastically displaced to be locked to the locking portion of the insertion piece and whose tip surface is locked to the locking portion. Have.

このようなステーと差し込み受け部からなる取り付け構造では、電気接続箱をステーに対して移動して、ステーの差し込み片に差し込み受け部を相対的に差し込むと、差し込み片の差し込み状態を差し込み受け部と係止爪が保持する。 In such a mounting structure consisting of a stay and an insertion receiving part, when the electrical junction box is moved relative to the stay and the insertion receiving part is relatively inserted into the insertion piece of the stay, the insertion state of the insertion piece is determined. And the retaining claws hold.

しかし、係止爪は差し込み片の差し込みに合わせて材料弾性で撓んで、係止部を通過させたのち弾性復帰して係止させるものであるため、係止爪の先端面と、これに対向する係止部との間には一定のクリアランスを設けておく必要がある。このため、差し込み片の差し込み方向でのガタつきが生じる難点がある。ガタつきは異音の発生の元となる。 However, the locking claw is bent by the elasticity of the material in accordance with the insertion of the insertion piece, and passes through the locking portion and then elastically returns and locks. It is necessary to provide a certain clearance between the engaging portions. For this reason, there exists a difficulty which the play in the insertion direction of an insertion piece arises. The looseness is a source of abnormal noise.

ステーと差し込み受け部との間のガタつきをなくそうとする発明として下記特許文献２に開示されたものがある。この取り付け構造は、係止爪の背部に蓋体に形成された差し込み片を差し込んで、係止爪が係止解除方向に撓まないようにするものである。 There is one disclosed in Patent Document 2 below as an invention for eliminating rattling between the stay and the insertion receiving portion. This attachment structure inserts the insertion piece formed in the lid on the back of the locking claw so that the locking claw does not bend in the locking release direction.

特許文献２の発明では、係止爪が撓む方向のガタつきは抑制できるが、差し込み片の差し込み方向でのガタつきを阻止することはできない。 In the invention of Patent Document 2, rattling in the direction in which the locking claw bends can be suppressed, but rattling in the insertion direction of the insertion piece cannot be prevented.

また、差し込み片と差し込み受け部との間のガタつきは、係止爪部分のクリアランスや撓みだけが原因ではない。製品の寸法公差もガタつきの原因になりうる。 Further, the backlash between the insertion piece and the insertion receiving portion is not caused only by the clearance or the deflection of the locking claw portion. Product dimensional tolerances can also cause play.

特開２０００−１８４５５５号公報JP 2000-184555 A 特開２００３−２３７１６号公報JP 2003-23716 A

そこでこの発明は、係止爪部分の構造に基づくガタつきのほか、寸法公差に基づくガタつきもなくせるようにすることを主な目的とする。 Accordingly, the main object of the present invention is to eliminate rattling based on dimensional tolerances in addition to rattling based on the structure of the locking claw portion.

そのための手段は、車両に設けられたステーと電気接続箱に形成された差し込み受け部との間で差し込みを行い、前記ステーの差し込み片の係止部に前記差し込み受け部の弾性係止片を押しつけて係止する電気接続箱の取り付け構造であって、前記差し込み受け部の内面における前記弾性係止片による押しつけ方向と反対側の部位に、差し込まれる前記差し込み片に接して、又は前記差し込み片によって変形されて差し込みを許容する規制突部を備えた電気接続箱の取り付け構造である。 Means for that purpose is to insert between a stay provided in the vehicle and an insertion receiving portion formed in the electrical junction box, and an elastic locking piece of the insertion receiving portion to the locking portion of the insertion piece of the stay. An electric junction box mounting structure for pressing and locking, wherein the insertion piece is in contact with or inserted into a portion of the inner surface of the insertion receiving portion opposite to the pressing direction by the elastic locking piece. It is the attachment structure of the electrical junction box provided with the control protrusion which deform | transforms by and accept | permits insertion.

この発明では、規制突部が差し込み片を弾性係止片による押しつけ方向と同じ方向に押しつけて位置規制を行う。押しつけに際して、規制突部は差し込み片に対して接し、又は差し込み片によって変形させられる。規制突部の変形により寸法公差を吸収する。このような位置規制によって差し込み受け部と差し込み片との間の相対移動を阻止して、ガタつきの発生をなくす。 In the present invention, the restricting protrusion presses the insertion piece in the same direction as the pressing direction by the elastic locking piece to restrict the position. At the time of pressing, the restricting protrusion comes into contact with or is deformed by the insertion piece. The dimensional tolerance is absorbed by the deformation of the restricting protrusion. Such positional restriction prevents relative movement between the insertion receiving portion and the insertion piece, and eliminates play.

この発明の態様として次のようにすることができる。すなわち、前記規制突部として前記差し込み受け部における前記押しつけ方向と反対側の面に形成された突条を備える。 As an aspect of the present invention, the following can be performed. That is, a protrusion formed on the surface of the insertion receiving portion opposite to the pressing direction is provided as the restricting protrusion.

この発明の突条は、差し込み片を対向側、つまり差し込み受け部における弾性係止片による押しつけ方向の面に押しつけて、弾性係止片と係止部の係合との協働で差し込み受け部と差し込み片との間の相対移動を阻止する。突条は特に差し込み片の厚み方向でのガタつきを積極的に阻止する。 The protrusion of the present invention presses the insertion piece against the opposite side, that is, the surface in the pressing direction of the insertion receiving portion by the elastic locking piece, and the insertion receiving portion cooperates with the engagement of the elastic locking piece and the locking portion. And prevent relative movement between the insertion piece. The protrusions positively prevent backlash in the thickness direction of the insertion piece.

この発明の態様として次のようにすることができる。すなわち、前記規制突部として前記差し込み受け部における前記押しつけ方向と反対側の両側の隅部に形成された隅突部を備える。 As an aspect of the present invention, the following can be performed. That is, as the restricting protrusion, corner protrusions formed at both corners on the opposite side to the pressing direction in the insertion receiving part are provided.

この発明の隅突部は、差し込み片の左右両側の角部に接触し、又はその角部によって変形させられて差し込み片を差し込み受け部における弾性係止片による押しつけ方向の面に押しつけて、弾性係止片と係止部の係合との協働で差し込み受け部と差し込み片との間の相対移動を阻止する。隅突部は特に差し込み片の左右方向でのガタつきを積極的に阻止する。 The corner protrusions of the present invention are in contact with the left and right corners of the insertion piece, or are deformed by the corners, and the insertion piece is pressed against the surface in the pressing direction by the elastic locking piece in the insertion receiving portion. Relative movement between the insertion receiving portion and the insertion piece is prevented by the cooperation of the engagement between the engagement piece and the engagement portion. The corner protrusions positively prevent the insertion piece from rattling in the left-right direction.

前記規制突部としては、前記突条と前記隅突部を兼ね備えるのが好ましい。寸法公差との関係で少なくともいずれか一方の規制突部が作用を果たすように設定することによって、対応可能な寸法公差の幅を広くすることができるとともに、双方の規制突部が作用したときには差し込み片の厚み方向でも左右方向でも積極的にガタつきを阻止できる。 It is preferable that the restricting protrusion has both the protrusion and the corner protrusion. By setting so that at least one of the restricting protrusions acts in relation to the dimensional tolerance, the width of the applicable dimensional tolerance can be widened, and when both restricting protrusions act, it is inserted. The rattle can be actively prevented in both the thickness direction and the left-right direction.

この発明の態様として、前記弾性係止片の係止爪における前記差し込み片の差し込み方向の前方と後方に、前記係止部の縁に斜めに当接する傾斜面を備えることができる。 As an aspect of the present invention, an inclined surface that obliquely abuts against an edge of the locking portion may be provided on the front and rear in the insertion direction of the insertion piece in the locking claw of the elastic locking piece.

この発明の弾性係止片の係止爪は、傾斜面が係止部の縁に当接するうえに、差し込み片は規制突部で押圧されるので、特に差し込み片の差し込み方向でのガタつきを良好に阻止できる。 In the locking claw of the elastic locking piece according to the present invention, the inclined surface abuts on the edge of the locking portion, and the insertion piece is pressed by the restricting projection, so that the insertion piece is particularly loose in the insertion direction. It can prevent well.

この発明の態様として、前記ステーにおける前記差し込み片よりも差し込み方向後方の両側縁に形成されて前記弾性係止片による押しつけ方向と同じ方向に起立する姿勢の補強片と、前記差し込み受け部に形成されて前記補強片を有する部分が嵌合する嵌合部を備え、前記規制突部を前記嵌合部に達する長さに形成することができる。 As an aspect of the present invention, a reinforcing piece formed on both side edges of the stay on the rear side of the insertion piece with respect to the insertion direction and standing in the same direction as the pressing direction by the elastic locking piece, and formed on the insertion receiving portion The fitting portion into which the portion having the reinforcing piece is fitted is fitted, and the regulation protrusion can be formed to a length reaching the fitting portion.

この発明の補強片はステーの剛性を高めるとともに、差し込み受け部の嵌合部との嵌合によって、ステーと差し込み受け部との間における差し込み片の幅方向及び厚み方向での傾き・回転を規制する。そして特に厚み方向での回転力に対しては、ステーにおける、差し込み受け部の嵌合部にまで形成された規制突部の端部に対応する部位が回転の支点となるが、この部分は補強片を有しており剛性が高いので、ステーの厚み方向にかかる回転力に対しても高い規制力を得られる。この結果、差し込み片部分に過負荷がかかるのを回避できる。 The reinforcing piece according to the present invention increases the rigidity of the stay and regulates the inclination / rotation in the width direction and the thickness direction of the insertion piece between the stay and the insertion receiving portion by fitting with the fitting portion of the insertion receiving portion. To do. And especially for the rotational force in the thickness direction, the part of the stay corresponding to the end of the restricting protrusion formed up to the fitting part of the insertion receiving part serves as a fulcrum of rotation. Since it has a piece and has high rigidity, a high regulation force can be obtained even with respect to the rotational force applied in the thickness direction of the stay. As a result, it is possible to avoid overloading the insertion piece.

課題を解決するための別の手段は、車両に設けられたステーの差し込み片が差し込まれる差し込み受け部を備え、該差し込み受け部には、前記差し込み片の係止部に対して押しつけて係止する弾性係止片を備えた電気接続箱であって、前記差し込み受け部の内面における前記弾性係止片による押しつけ方向と反対側の部位に、差し込まれる前記差し込み片に接して、又は前記差し込み片によって変形されて差し込みを許容する規制突部を備えた電気接続箱である。 Another means for solving the problem includes an insertion receiving portion into which an insertion piece of a stay provided in the vehicle is inserted, and the insertion receiving portion is pressed against the locking portion of the insertion piece to be locked. An electrical connection box having an elastic locking piece that is in contact with the insertion piece inserted into a portion of the inner surface of the insertion receiving portion opposite to the pressing direction by the elastic locking piece, or the insertion piece It is an electrical junction box provided with the control protrusion which deform | transforms by and accept | permits insertion.

この発明では、差し込まれる差し込み片に対して、規制突部が差し込み片を弾性係止片による押しつけ方向と同じ方向に押しつけて位置規制を行う。押しつけに際して、規制突部は差し込み片に対して接し、又は差し込み片によって変形させられる。規制突部の変形により寸法公差を吸収する。このような位置規制によって差し込み受け部と差し込み片との間の相対移動を阻止して、ガタつきの発生をなくす。 In this invention, with respect to the inserted piece to be inserted, the restricting protrusion presses the inserted piece in the same direction as the pressing direction by the elastic locking piece to perform position restriction. At the time of pressing, the restricting protrusion comes into contact with or is deformed by the insertion piece. The dimensional tolerance is absorbed by the deformation of the restricting protrusion. Such positional restriction prevents relative movement between the insertion receiving portion and the insertion piece, and eliminates play.

この発明の態様として次のようにすることができる。すなわち、前記規制突部として前記差し込み受け部における前記押しつけ方向と反対側の隅部に形成された隅突部を備える。 As an aspect of the present invention, the following can be performed. That is, a corner protrusion formed at the corner opposite to the pressing direction in the insertion receiving portion is provided as the restriction protrusion.

この発明によれば、弾性係止片の係止爪部分でのガタつき防止はもちろんのこと、寸法公差に基づくガタつきもなくせて、良好な取り付け状態が得られる。この結果、ガタつきに基づく異音の発生も防止できる。 According to the present invention, it is possible not only to prevent backlash at the locking claw portion of the elastic locking piece, but also to eliminate backlash based on dimensional tolerances, and a good mounting state can be obtained. As a result, it is possible to prevent the generation of abnormal noise due to rattling.

この電気接続箱１１の取り付け構造は、ブラケットを横断する方向の縦断面図（図６のＡ−Ａ断面図）である図４に示したように、車両に設けられたステー２１とブラケット１４に形成された差し込み受け部３１との間で差し込みを行い、ステー２１の差し込み片２２の係止部２３に差し込み受け部３１の弾性係止片３２を押し付けて係止するものである。 As shown in FIG. 4, which is a longitudinal sectional view (A-A sectional view of FIG. 6) in a direction crossing the bracket, the electrical junction box 11 is attached to a stay 21 and a bracket 14 provided on the vehicle. Insertion is performed between the formed insertion receiving portion 31, and the elastic locking piece 32 of the insertion receiving portion 31 is pressed and locked to the locking portion 23 of the insertion piece 22 of the stay 21.

図示例の電気接続箱１１はステー２１による取り付けに加えてボルトナット（図示せず）による取り付けで車両に搭載されるものであるが、電気接続箱１１はステー２１を用いた取り付け構造のみで取り付けるものであってもよい。 The electrical connection box 11 in the illustrated example is mounted on the vehicle by mounting with bolts and nuts (not shown) in addition to mounting with the stay 21, but the electrical connection box 11 is mounted only with a mounting structure using the stay 21. It may be a thing.

参考までに付言すると、図示例の電気接続箱１１は、先端側部分が車両の後方に向くステー２１に対して縦長に取り付けられるものであり、ステー２１によって上端部が固定される（図１参照）。これは一例であり、ステー２１の向きや電気接続箱１１の形態、構造などは、電気接続箱１１の取り付け部位などに応じて適宜設計される。 For reference, the electrical connection box 11 in the illustrated example is attached vertically to a stay 21 whose front end portion faces the rear of the vehicle, and the upper end is fixed by the stay 21 (see FIG. 1). ). This is an example, and the orientation of the stay 21 and the form and structure of the electrical junction box 11 are appropriately designed according to the attachment site of the electrical junction box 11 and the like.

まず、ステー２１について簡単に説明し、続いて電気接続箱１１のロアケース１２のブラケット１４について説明する。 First, the stay 21 will be briefly described, and then the bracket 14 of the lower case 12 of the electrical junction box 11 will be described.

ステー２１は金属製で、図１に示したように、板材をプレスして形成されている。ステー２１は先端部に略方形状の差し込み片２２を有し、この差し込み片２２の中央に貫通穴からなる方形状の係止部２３を有している。ステー２１の差し込み片２２よりも差し込み方向後方側の部分は、差し込み片２２の幅よりも幅広で長方形板状の本体板部２４である。この本体板部２４の両側縁には剛性を高める補強片２５が折り曲げにより形成されている。２本の補強片２５は同一方向、具体的には弾性係止片３２による押しつけ方向と同じ方向に向けて形成されており、本体板部２４から起立する姿勢である。本体板部２４と補強片２５との間には、角アール部２６が形成されている。 The stay 21 is made of metal and is formed by pressing a plate material as shown in FIG. The stay 21 has a substantially square-shaped insertion piece 22 at the tip, and a square-shaped locking portion 23 formed of a through hole at the center of the insertion piece 22. A portion of the stay 21 on the rear side of the insertion piece 22 with respect to the insertion piece 22 is a main body plate portion 24 that is wider than the insertion piece 22 and has a rectangular plate shape. Reinforcing pieces 25 for enhancing rigidity are formed on both side edges of the main plate 24 by bending. The two reinforcing pieces 25 are formed in the same direction, specifically, in the same direction as the pressing direction by the elastic locking pieces 32, and stand up from the main body plate portion 24. A corner radius portion 26 is formed between the main body plate portion 24 and the reinforcing piece 25.

ブラケット１４は、図１、図２、図３に示したように合成樹脂製のロアケース１２の一側面に形成されている。図５はブラケット１４をステー２１に対する差し込み方向側から見た正面図で、図６はブラケット１４の平面図である。これらの図に示すようにブラケット１４は正面視等脚台形状で、ステー２１を差し込む差し込み受け部３１が内部に形成されている。 As shown in FIGS. 1, 2, and 3, the bracket 14 is formed on one side surface of the lower case 12 made of synthetic resin. FIG. 5 is a front view of the bracket 14 as seen from the insertion direction side with respect to the stay 21, and FIG. 6 is a plan view of the bracket 14. As shown in these drawings, the bracket 14 has an isosceles trapezoidal shape when viewed from the front, and an insertion receiving portion 31 into which the stay 21 is inserted is formed inside.

差し込み受け部３１は、ステー２１の先端側部分を保持する部分で、ステー２１の対応部分の形状に嵌合対応する形状である。差し込み受け部３１の左右方向の両側部にはステー２１の左右両側部を保持する保持溝３３を有し、左右方向の中間部には差し込み方向に貫通する貫通穴３４を有している。この貫通穴３４の天井面に、貫通穴３４の幅方向の中間位置を切断部分とする断面図である図７に示したように弾性係止片３２が形成されている。弾性係止片３２は貫通穴３４の天井面から離れる方向に材料弾性による付勢力を発揮し、図８に示したようにステー２１の差し込み片２２の係止部２３に下面の係止爪３５を押しつける。 The insertion receiving portion 31 is a portion that holds the tip side portion of the stay 21, and has a shape corresponding to the shape of the corresponding portion of the stay 21. A holding groove 33 for holding the left and right side portions of the stay 21 is provided on both side portions of the insertion receiving portion 31 in the left and right direction, and a through hole 34 penetrating in the insertion direction is provided on an intermediate portion in the left and right direction. An elastic locking piece 32 is formed on the ceiling surface of the through hole 34 as shown in FIG. 7, which is a cross-sectional view with an intermediate position in the width direction of the through hole 34 as a cut portion. The elastic locking piece 32 exerts a biasing force due to material elasticity in a direction away from the ceiling surface of the through hole 34, and as shown in FIG. 8, the locking claw 35 on the lower surface of the locking portion 23 of the insertion piece 22 of the stay 21. Press.

左右両側の保持溝３３は、図４に示したように縦断面コ字状で、先端には差し込まれたステー２１の差し込み片２２の先端面が当接する当接面３６を有している（図４、図５、図６参照）。この保持溝３３の内面における弾性係止片３２による押しつけ方向と反対側の部位に、差し込まれる差し込み片２２に接して、又は差し込み片２２によって変形されて差し込みを許容する規制突部３７を備えている。 As shown in FIG. 4, the holding grooves 33 on both the left and right sides have a U-shaped longitudinal section, and have a contact surface 36 with which the front end surface of the insertion piece 22 of the stay 21 inserted is in contact with the front end ( (See FIGS. 4, 5, and 6). On the inner surface of the holding groove 33 on the opposite side of the pressing direction by the elastic locking piece 32 is provided with a regulating protrusion 37 that is in contact with the inserted piece 22 to be inserted or is deformed by the inserted piece 22 to allow insertion. Yes.

規制突部３７は二種類備えている。一つは、保持溝３３における弾性係止片３２による押しつけ方向と反対側面、つまり保持溝３３の天井面に形成された突条３８である。他のひとつは、保持溝３３における弾性係止片３２による押しつけ方向と反対側の両側の隅部、つまり保持溝３３の天井面側のコーナに形成された隅突部３９である。 There are two types of restriction protrusions 37. One is a protrusion 38 formed on the side of the holding groove 33 opposite to the pressing direction by the elastic locking piece 32, that is, on the ceiling surface of the holding groove 33. The other one is a corner protrusion 39 formed at a corner on both sides of the holding groove 33 opposite to the pressing direction by the elastic locking piece 32, that is, a corner on the ceiling surface side of the holding groove 33.

突条３８は、保持溝３３の天井面のうち差し込み受け部３１の左右方向中間の貫通穴３４に近い位置に形成され（図４参照）、差し込み方向にのびている。図示例では突条３８の先端の断面形状を半円弧状としたが、例えば三角形状など、その他の形状であってもよい。 The protrusion 38 is formed in the ceiling surface of the holding groove 33 at a position close to the through hole 34 in the middle in the left-right direction of the insertion receiving portion 31 (see FIG. 4) and extends in the insertion direction. In the illustrated example, the cross-sectional shape of the tip of the protrusion 38 is a semicircular arc shape, but may be other shapes such as a triangular shape.

隅突部３９は縦断面三角形状で、差し込み受け部３１の左右方向中間下方に向く平らな傾斜面３９ａを有している（図４参照）。傾斜面３９ａの傾斜角は、適宜設定されるが、天井面に対して例えば６０度程度の傾斜であるとよい。隅突部３９は、図示例のような平らな傾斜面３９ａを有する形状のほか、たとえば湾曲面を有るものであってもよい。 The corner projection 39 has a triangular shape in vertical section, and has a flat inclined surface 39a facing the lower middle in the left-right direction of the insertion receiving portion 31 (see FIG. 4). Although the inclination angle of the inclined surface 39a is set as appropriate, the inclination angle is preferably about 60 degrees with respect to the ceiling surface. The corner protrusion 39 may have, for example, a curved surface in addition to the shape having the flat inclined surface 39a as in the illustrated example.

このような隅突部３９は、隅突部３９部分を切断部分とする断面図である図９に示したように、保持溝３３のうち差し込み方向前方の差し込み片受け部３３ａに形成されている。差し込み片受け部３３ａは、図６、図１０に示したように、ステー２１の差し込み片２２が差し込まれる部分である。つまり、差し込み片２２が差し込み受け部３３ａに対して差し込まれることによって、差し込み片２２は隅突部３９と接し、又は隅突部３９を変形し得る。 Such a corner protrusion 39 is formed in the insertion piece receiving portion 33a ahead of the insertion direction in the holding groove 33, as shown in FIG. 9 which is a cross-sectional view with the corner protrusion 39 portion being a cut portion. . The insertion piece receiving portion 33a is a portion into which the insertion piece 22 of the stay 21 is inserted as shown in FIGS. That is, by inserting the insertion piece 22 into the insertion receiving portion 33a, the insertion piece 22 can contact the corner protrusion 39 or deform the corner protrusion 39.

差し込み片受け部３３ａより後方は、ステー２１の差し込み片２２よりも後方の補強片２５を有する部分が嵌合する嵌合部３３ｂである。この嵌合部３３ｂと差し込み片受け部３３ａとの間には、差し込みしやすくするテーパ面３１ｃが形成されている（図５参照）。 Behind the insertion piece receiving portion 33a is a fitting portion 33b into which a portion having the reinforcing piece 25 behind the insertion piece 22 of the stay 21 is fitted. A tapered surface 31c that facilitates insertion is formed between the fitting portion 33b and the insertion piece receiving portion 33a (see FIG. 5).

隅突部３９が保持溝３３の先端側の差し込み片受け部３３ａに形成されているのに対して、突条３８は、嵌合部３３ｂに達する長さ、つまり突条３８部分を切断部分とする断面図である図１１に示したように差し込み受け部３１全体にわたって形成されている。具体的には、差し込み受け部３１の入口のテーパ面３１ａを除いた全体に形成されている。これによって、図１２に示したように、ステー２１における差し込み受け部３１のテーパ面３１ａより先に対応する部分全体が、突条３８と接し、又は突条３８によって変形され得る。 Whereas the corner protrusion 39 is formed in the insertion piece receiving portion 33a on the distal end side of the holding groove 33, the protrusion 38 has a length reaching the fitting portion 33b, that is, the protrusion 38 portion is defined as a cut portion. As shown in FIG. 11, which is a cross-sectional view, it is formed over the entire insertion receiving portion 31. Specifically, it is formed in the whole except the taper surface 31a of the entrance of the insertion receptacle part 31. FIG. Accordingly, as shown in FIG. 12, the entire portion of the stay 21 corresponding to the taper surface 31 a of the insertion receiving portion 31 can be in contact with or deformed by the protrusion 38.

弾性係止片３２は、図６に示したように平面視長方形状であり、弾性係止片３２の幅方向の中間位置を切断部分とする断面図である図７、図８に示したように一端部が差し込み受け部３１の天井面に接続された片持ち状である。差し込み受け部３１の前方にのびた自由端である先端部は、差し込み受け部３１の貫通穴３４から突出している。係止爪３５は先端側部分における下面中央に、平面視方形状に形成されている。係止爪３５は、図８に示したように差し込み方向の前方と後方に、ステー２１の差し込み片２２の係止部２３の縁に斜めに当接する傾斜面３５ａ，３５ｂを備えている。前方の傾斜面３５ａと後方の傾斜面３５ｂはそれぞれ、前方斜め下方、後方斜め下方に向いており、係止部２３に内側斜め上方から外側斜め下方に向けて接する。 As shown in FIGS. 7 and 8, the elastic locking piece 32 has a rectangular shape in plan view as shown in FIG. 6, and is a cross-sectional view with an intermediate position in the width direction of the elastic locking piece 32 as a cut portion. The cantilever is connected to the ceiling surface of the insertion receiving portion 31 at one end. A tip portion that is a free end extending forward of the insertion receiving portion 31 protrudes from the through hole 34 of the insertion receiving portion 31. The locking claw 35 is formed in a planar view shape at the center of the lower surface of the tip side portion. As shown in FIG. 8, the locking claw 35 includes inclined surfaces 35 a and 35 b that obliquely abut against the edge of the locking portion 23 of the insertion piece 22 of the stay 21 at the front and rear in the insertion direction. The front inclined surface 35a and the rear inclined surface 35b face diagonally forward and downward, respectively, and contact the locking portion 23 from diagonally upward on the inside to diagonally downward on the outside.

このような構成の差し込み受け部３１の寸法について、次に説明する。 Next, the dimensions of the insertion receiving portion 31 having such a configuration will be described.

差し込み受け部３１は前述のようにステー２１の先端側部分が差し込まれる部分であるので、差し込み受け部３１がステー２１を差し込み可能となる寸法であることはもちろんであるが、寸法公差に基づくガタつきをなくすため、差し込み受け部３１とステー２１との間で寸法公差による違いが最も小さい場合に規制突部３７とステー２１が接し、それよりも大きい場合にステー２１の差し込みにより規制突起３７が変形するように規制突起３７の大きさが設定される。寸法公差による違いが最も小さい場合でもステー２１の差し込みにより規制突起３７が変形するように規制突起３７の大きさを設定してもよい。 Since the insertion receiving portion 31 is a portion into which the distal end portion of the stay 21 is inserted as described above, the insertion receiving portion 31 is of a dimension that allows the stay 21 to be inserted, but of course, the backlash is based on a dimensional tolerance. In order to eliminate sticking, the restriction projection 37 and the stay 21 are in contact with each other when the difference in dimensional tolerance between the insertion receiving portion 31 and the stay 21 is the smallest, and when the difference is larger than that, the restriction projection 37 is inserted by the stay 21 insertion. The size of the restricting projection 37 is set so as to be deformed. Even when the difference due to dimensional tolerance is the smallest, the size of the restriction projection 37 may be set so that the restriction projection 37 is deformed by insertion of the stay 21.

好ましい一例を示すと、つぎのようになる。 A preferred example is as follows.

ステー２１の厚さと突条３８の先端高さとの関係に関して、図１３に示したように、突条３８の先端と突条３８の対向面、つまり保持部３３における弾性係止片３２による押しつけ方向側の面（保持溝３３の下面）との間の距離ｈは、ステー２１の差し込み片２２の厚さｔの寸法公差の最小値以下である。 Regarding the relationship between the thickness of the stay 21 and the tip height of the protrusion 38, as shown in FIG. 13, the pressing direction by the elastic locking piece 32 in the opposing surface of the protrusion 38 and the protrusion 38, that is, the holding portion 33. The distance h from the side surface (the lower surface of the holding groove 33) is equal to or less than the minimum value of the dimensional tolerance of the thickness t of the insertion piece 22 of the stay 21.

このように設定すると、差し込み片２２の差し込みによって突条３８は、差し込み片２２と接するか、押し潰されて変形することになり、ステー２１の差し込み片２２を確実に保持溝３３の下面に対して押しつけることができる。この結果、ステー２１の厚さ方向でのガタつきを阻止できる。 With this setting, the protrusion 38 comes into contact with the insertion piece 22 or is crushed and deformed by the insertion of the insertion piece 22, so that the insertion piece 22 of the stay 21 can be securely attached to the lower surface of the holding groove 33. Can be pressed. As a result, the play of the stay 21 in the thickness direction can be prevented.

ステー２１の幅と隅突部３９の大きさとの関係に関して、図１４に示したように、左右両側の隅突部３９の傾斜面３９ａ同士の間のステー２１の差し込み片２２の上面位置における距離ｗ１は、ステー２１の差し込み片２２の幅ｗ２との寸法公差の違いが大きい場合にｗ１＞ｗ２となって、差し込み片２２の上面側の両角と傾斜面３９ａとの間に適宜の隙間ができ、違いが小さい場合にｗ１＜Ｗ２となって、図１５に示したように差し込み片２２の上面の両角が隅突部３９に干渉する大きさである。 Regarding the relationship between the width of the stay 21 and the size of the corner protrusion 39, as shown in FIG. 14, the distance at the upper surface position of the insertion piece 22 of the stay 21 between the inclined surfaces 39 a of the left and right corner protrusions 39. When the difference in dimensional tolerance from the width w2 of the insertion piece 22 of the stay 21 is large, w1 becomes w1> w2, and an appropriate gap is formed between both corners on the upper surface side of the insertion piece 22 and the inclined surface 39a. When the difference is small, w1 <W2, and the two corners of the upper surface of the insertion piece 22 interfere with the corner protrusion 39 as shown in FIG.

このように設定すると、差し込み片２２の差し込みによって隅突部３９は、差し込み片２２と接しないか、接するか、押し潰されて変形することになり、接するか、変形したときにはステー２１の差し込み片２２を確実に挟み込んで保持溝３３の下面に対して押しつけることができる。突条３８との関係でいえば、寸法公差による寸法の違いが小さい場合で突条３８の潰れ度合いが大きくなるときに、隅突部３９が差し込み片２２に接して、又は差し込み片２２によって変形されて、突条３８による押圧力の低下を補う。この結果、ステー２１のガタつき、特に左右方向でのガタつきを阻止できる。 With this setting, the corner projection 39 does not contact with the insertion piece 22 or is deformed by being crushed by the insertion of the insertion piece 22, and when the contact piece is deformed, the insertion piece of the stay 21 is inserted. 22 can be securely sandwiched and pressed against the lower surface of the holding groove 33. In terms of the relationship with the ridge 38, when the dimensional difference due to dimensional tolerance is small and the degree of crushing of the ridge 38 increases, the corner protrusion 39 contacts the insertion piece 22 or is deformed by the insertion piece 22. Thus, the decrease in the pressing force due to the protrusion 38 is compensated. As a result, it is possible to prevent the stay 21 from rattling, particularly in the left-right direction.

以上のように構成された電気接続箱１１の取り付け構造では、次のような作用効果を有する。 The mounting structure of the electrical junction box 11 configured as described above has the following operational effects.

電気接続箱１１の取り付けは、車両から突出しているステー２１に対して電気接続箱１１のブラケット１４の差し込み受け部３１を差し込む。差し込み受け部３１はステー２１の相対的な差し込みを受け、ステー２１の両側縁部を保持溝３３で保持するとともに、弾性係止片３２の係止爪３５でステー２１の差し込み片２２の係止部２３を係止する。係止爪３５は、前後両側の傾斜面３５ａ，３５ｂを係止部２３の縁に内側斜め上方から外側斜め下方に向けて斜めに当てるので、係止爪３５が係止部２３を押さえつけている限りにおいて前後方向での相対移動をガタつきなく阻止できる。 The electrical connection box 11 is attached by inserting the insertion receiving portion 31 of the bracket 14 of the electrical connection box 11 into the stay 21 protruding from the vehicle. The insertion receiving portion 31 receives the relative insertion of the stay 21, holds both side edges of the stay 21 with the holding grooves 33, and locks the insertion piece 22 of the stay 21 with the locking claw 35 of the elastic locking piece 32. The part 23 is locked. Since the locking claw 35 obliquely applies the inclined surfaces 35a and 35b on both the front and rear sides to the edge of the locking part 23 from the diagonally upper side to the diagonally downward side, the locking claw 35 presses the locking part 23. As far as possible, relative movement in the front-rear direction can be prevented without rattling.

そして係止爪３５を有する弾性係止片３２は、差し込み受け部３１に差し込み片２２を差し込んだときに、規制突部３７のうちの少なくとも突条３８が差し込み片２２の対向面に接し、又は差し込まれる差し込み片２２によって潰されて変形し、差し込み片２２を係止爪３５による押しつけ方向に押さえつける。突条３８の先端は曲面で差し込み方向に延びる線状であるので、また隅突部３９は平らな傾斜面３９ａが差し込み片２２の角に当たるので、ステー２１と規制突部３７が干渉する関係にある場合でも差し込みは良好に行える。 The elastic locking piece 32 having the locking claw 35 is such that at least the protrusion 38 of the restricting protrusion 37 contacts the opposite surface of the insertion piece 22 when the insertion piece 22 is inserted into the insertion receiving portion 31, or The insertion piece 22 is crushed and deformed by being inserted, and the insertion piece 22 is pressed in the pressing direction by the locking claw 35. Since the tip of the protrusion 38 is a curved line that extends in the insertion direction, and the corner protrusion 39 has a flat inclined surface 39a that hits the corner of the insertion piece 22, the stay 21 and the restricting protrusion 37 interfere with each other. Even in some cases, it can be inserted well.

前述のように規制突部３７が差し込み片２２を係止爪３５による押しつけ方向に押さえつけるので、係止爪３５と係止部２３による係止状態を強固に維持できる。そのうえ、突条３８が差し込み片２２を必ず押しつけることになるため、弾性係止片３２が係止解除方向に動くことはなく、突条３８による押圧力によって、ステー２１の厚み方向と左右方向でのガタつき、特にステー２１の厚み方向でのガタつきをなくすことができる。 As described above, since the restricting protrusion 37 presses the insertion piece 22 in the pressing direction by the locking claw 35, the locked state by the locking claw 35 and the locking portion 23 can be maintained firmly. In addition, since the ridge 38 necessarily presses the insertion piece 22, the elastic locking piece 32 does not move in the locking release direction, and the pressing force by the ridge 38 causes the stay 21 in the thickness direction and the left-right direction. Can be eliminated, particularly in the thickness direction of the stay 21.

規制突部３７として隅突部３９も突条３８と同時に差し込み片２２に接し、又は変形させられた場合には、ステー２１の左右方向でのガタつきも積極的になくすことができる。 When the corner protrusion 39 as the restriction protrusion 37 is also in contact with the insertion piece 22 at the same time as the protrusion 38 or is deformed, the play of the stay 21 in the left-right direction can be actively eliminated.

しかも、突条３８と隅突部３９は必要に応じて変形することによって、寸法公差を吸収する。このため、寸法公差に基づくガタつきの発生をなくすことができる。 In addition, the protrusions 38 and the corner protrusions 39 are deformed as necessary to absorb dimensional tolerances. For this reason, the occurrence of rattling based on dimensional tolerance can be eliminated.

突条３８と隅突部３９は共に、差し込み片２２を保持溝３３の下面に対して押しつけるが、特に隅突部３９は傾斜面３９ａを有するので、接触又は干渉する差し込み片２２を保持溝３３同士の間の中間位置に寄せる作用も果たす。この作用によって、差し込み片２２を正しい位置に差し込むことができ、係止爪３５と係止部２３との適切な係止を確実にできる効果も有する。 Both the protrusion 38 and the corner protrusion 39 press the insertion piece 22 against the lower surface of the holding groove 33. In particular, since the corner protrusion 39 has an inclined surface 39a, the insertion piece 22 that comes into contact with or interferes with is held in the holding groove 33. It also serves to move to an intermediate position between them. By this action, the insertion piece 22 can be inserted into a correct position, and there is also an effect that appropriate locking between the locking claw 35 and the locking portion 23 can be ensured.

そのうえ規制突部３７として、必ず差し込み片２２に接する突条３８を備えるとともに、これに加えて隅突部３９を備えたので、対応可能な寸法公差の幅を広くすることができる。 In addition, the regulation protrusion 37 is provided with a protrusion 38 that always contacts the insertion piece 22 and a corner protrusion 39 in addition to this, so that the width of the dimensional tolerance that can be handled can be widened.

前述のように寸法公差も吸収してガタつきを皆無にすることができるので、ガタつきに基づく異音の発生もなくすことができる。 As described above, since the dimensional tolerance can be absorbed and the rattling can be eliminated, the generation of abnormal noise due to the rattling can be eliminated.

また、差し込み受け部３１にはステー２１の補強片２５を有する部分が嵌合する嵌合部３３ｂを備え、嵌合部３３ｂにまで突条３８を形成したので、ステー２１と差し込み受け部３１との間における差し込み片２２の幅方向及び厚み方向での傾き・回転を積極的に規制することができる。つまり、ステー２１の特に厚み方向にかかる回転力に対しては、ステー２１における嵌合部３３ｂの突条３８の端部に対応する部位が回転の支点となるが、この部分は補強片２５を有しており剛性が高いので、ステー２１の厚み方向にかかる回転力に対しても高い規制力を得られる。これによって、ステー２１の差し込み片２２部分に過負荷がかかるのを回避でき、ステー２１の強度を確保し、ひいては電気接続箱１１の取り付け強度を高めることができる。 Moreover, since the insertion receiving part 31 is provided with the fitting part 33b which the part which has the reinforcement piece 25 of the stay 21 fits, and the protrusion 38 was formed in the fitting part 33b, the stay 21, the insertion receiving part 31, and Inclination / rotation in the width direction and thickness direction of the insertion piece 22 in between can be positively regulated. That is, with respect to the rotational force applied to the stay 21 particularly in the thickness direction, the portion of the stay 21 corresponding to the end portion of the protrusion 38 of the fitting portion 33b serves as a fulcrum of rotation. Since it has a high rigidity, a high regulation force can be obtained even with respect to the rotational force applied in the thickness direction of the stay 21. As a result, it is possible to avoid overloading the insertion piece 22 portion of the stay 21, to ensure the strength of the stay 21, and to increase the mounting strength of the electrical junction box 11.

以上はこの発明を実施するための一形態の構成であり、この発明は前述の構成のみに限定されるものではなく、その他の構成を採用することができる。 The above is the configuration of one form for carrying out the present invention, and the present invention is not limited to the above-described configuration, and other configurations can be adopted.

たとえば、規制突部としては突条または隅突部の一方のみを備えるものであっても、その他の形状の規制突部を備えてもよい。 For example, the restriction protrusion may be provided with only one of a protrusion or a corner protrusion, or may be provided with a restriction protrusion having another shape.
