【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、電気接続箱を車体に固定し、あるいは電気
接続箱の上部および下部ケースを互いに固定するための
構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a structure for fixing an electric connection box to a vehicle body or fixing an upper and lower case of the electric connection box to each other.
従来、この種の固定構造として第３図および第４図に
示すようなものがある（実開昭56-136427号公報）。Conventionally, there is a fixing structure of this kind as shown in FIGS. 3 and 4 (Japanese Utility Model Laid-Open No. 56-136427).
図において、１は電気接続箱のケース本体であって、
車体のブラケット４に対する取付部２が突設されてい
る。なお、ケース本体１には図示しない下部ケースがロ
ック手段により固定されている。In the figure, reference numeral 1 denotes a case body of an electric connection box,
A mounting portion 2 for a bracket 4 of the vehicle body is protruded. Note that a lower case (not shown) is fixed to the case body 1 by locking means.
この取付部２のブラケット４側には、そのあな2aと連
通するあな3aをもつ緩衝材３が接着されており、ボルト
５およびナット６により取付部２をブラケット４に締付
固定する際に、取付部２の座屈や破損を防止する構造と
なっている。A cushioning material 3 having a hole 3a communicating with the hole 2a is adhered to the bracket 4 side of the mounting portion 2, and when the mounting portion 2 is tightened and fixed to the bracket 4 by bolts 5 and nuts 6, The structure is such that the buckling or breakage of the mounting portion 2 is prevented.
従来の固定構造において、ボルト・ナットの締付力
は、緩衝材３が介在しても直接樹脂製の取付部２に作用
する。従って、ある一定以上の力が加わると、著しい座
屈が見られ、激しいときは破損してしまう。In the conventional fixing structure, the tightening force of the bolt / nut acts directly on the resin mounting portion 2 even with the buffer material 3 interposed. Therefore, when a certain force or more is applied, remarkable buckling is observed, and when it is severe, it is broken.
また、ボルト・ナットのゆるみトルクは樹脂への圧縮
荷重からのみ得られるから、高温などのクリープ現象に
より荷重低下、すなわちゆるみが生じやすい。Further, since the loosening torque of the bolt / nut is obtained only from the compressive load on the resin, the load is reduced, that is, loosened easily due to a creep phenomenon such as high temperature.
さらに、取付部２がケース本体１または下部ケースの
一方にしか付いていないために、他方はロック手段で保
持固定されるにすぎず、振動等が激しい箇所での取り付
けには不向きである。Further, since the mounting portion 2 is attached to only one of the case main body 1 and the lower case, the other is merely held and fixed by the locking means, and is not suitable for mounting in a place where vibration or the like is severe.
本考案の課題は、以上のような問題点を解消し、取付

拡開した弾性カシメ部を形成させて、上部および下部ケ
ースを同時に固定し得る構成を採用した。In order to achieve the above object, according to the present invention, a mounting portion having a hole facing a butt portion of an upper case and a lower case of an electric connection box is provided, and a funnel-shaped opening is provided in a hole of one of the mounting portions. Is formed, and a collar having a flange-like flange at one end and a cut at the other end is inserted into the holes of both mounting portions, a bolt is inserted into the collar and tightened with a nut, and the opening is closed. At the other end of the collar, a funnel-shaped expanded elastic caulking portion was formed to adopt a configuration capable of simultaneously fixing the upper and lower cases.
以下、上記構成を実施例を示す図面を参照して具体的
に説明する。Hereinafter, the above configuration will be specifically described with reference to the drawings showing the embodiments.
第１図に本考案に係る電気接続箱の分解斜視図、第２

・ With, fuse 14, fusible link 15, relay
Electrical parts such as 16, 17 can be connected.
Further, the lower case 11 includes a connector 18 for connecting a wire harness (not shown). Furthermore, on the longitudinal side wall, which is the abutting portion of the two cases 10, 11,
Locking means each comprising a locking frame 19 and a locking claw 20 that engages with the locking frame 19 is provided.
以上は従来と同様の構成であるが、本考案において
は、上記ケース10と下部ケース11の突き合わせ部の両端
側に、それぞれ相対する取付部21と22が一体に形成され
ている。The above configuration is the same as that of the related art, but in the present invention, opposing mounting portions 21 and 22 are integrally formed on both ends of the butted portion of the case 10 and the lower case 11, respectively.
取付部21,22はそれぞれボルト30を通すための連通す
る孔23,24を有し、また、第２図a,bに示されるように、
一方の取付部21の先端に位置決め用の凸部25が、他方の
取付部22に対応する凹部26に形成されている。Each of the mounting portions 21 and 22 has a communicating hole 23 and 24 for passing the bolt 30, and as shown in FIGS. 2a and 2b,
A positioning projection 25 is formed at the tip of one mounting portion 21 in a concave portion 26 corresponding to the other mounting portion 22.
一方の取付部21の孔23は、他方の取付部22との突き合
わせ面と反対側にロート状の開口部23aが形成されてい
る。The hole 23 of the one mounting portion 21 has a funnel-shaped opening 23a formed on the side opposite to the abutting surface with the other mounting portion 22.
27は、上記孔23,24に貫通して挿着される金属製のカ

は複数の切込みを入れるのが有効である。Reference numeral 27 denotes a metal collar that is inserted through the holes 23 and 24 and has a flange-like flange 28 at one end. The length of the collar 27 is slightly longer than the thickness of the mounting portions 21 and 22 at the time of overlapping, and is formed as an elastic caulking portion 29 having a tip protruding from one of the holes 23. Elastic caulking part 29
It is effective to make multiple cuts.

To the holes 23 and 24 of the mounting parts 21 and 22
27 is penetrated from below. Further, the elastic caulking portion 29 is compressed from above with a conical rod and caulked. The above-described elastic caulking portion 29 is opened in a funnel shape as shown in FIG. 2A by caulking, and further tightened to obtain the elastic caulking portion 29 as shown in FIG. 2B.
Is expanded so as to be substantially in close contact with the mounting portion 21 including the funnel-shaped opening 23a of the hole 23. Thereby, the mounting part 2
The first and the second are closely contacted without any gap, so that the noise caused by the play of the mounting portion does not occur. Then, the bolt 30 is inserted from the elastic caulking portion 29 side of the collar 27, the nut 31 is lightly screwed into the bolt 30 protruding toward the flange 28, and then tightened and fixed with a tool such as a torque wrench as shown in FIG. 2b. I do.
締め付けに際し、ボルト30およびナット31はそれぞれ
合成樹脂製の取付部21,22には直接接触せず、鍔28また
は弾性カシメ部29に接触する。また、締付時の圧縮力に
対しては円筒体であるカラー27が対抗する。At the time of tightening, the bolt 30 and the nut 31 do not directly contact the synthetic resin mounting portions 21 and 22, respectively, but contact the flange 28 or the elastic caulking portion 29. The collar 27, which is a cylindrical body, opposes the compressive force at the time of tightening.
従って、取付部21および22は、ボルト・ナットの締付
力から保護され、座屈、破壊等の損傷を受けない。そし
て、弾性カシメ部29の存在により取付部21,22は上下か
ら同時に弾性的に挟持固定される。Therefore, the mounting portions 21 and 22 are protected from the tightening force of the bolts and nuts, and do not suffer damage such as buckling or breakage. Then, due to the presence of the elastic caulking portion 29, the mounting portions 21 and 22 are simultaneously elastically clamped and fixed from above and below.
さらに、円筒体であるカラー27の圧縮に対する反発力
により、ボルト・ナットのねじ山同志が噛み合い、その
摩擦力によりゆるみトルクが生じる。カラー27は金属製
であるから、合成樹脂とは異なり、クリープ現象が生じ
にくく、ゆるみトルクも増大する。Further, the repulsive force against the compression of the collar 27, which is a cylindrical body, engages the threads of the bolt and the nut, and the frictional force generates a loosening torque. Since the collar 27 is made of metal, unlike a synthetic resin, a creep phenomenon is unlikely to occur, and the loosening torque increases.
以上は、電気接続箱Ａの上部ケース10と下部ケース11
のみの固定であるが、従来例を示す第４図のように、車
体のブラケット４に取り付ける場合も同様である。The above is the description of the upper case 10 and the lower case 11 of the electric junction box A.
Only the fixing is carried out, but the same applies to the case where it is attached to the bracket 4 of the vehicle body as shown in FIG. 4 showing a conventional example.
以上説明したように、本考案の電気接続箱の固定構造

共に、一方の取付部の孔にロート状の開口部を形成し、
一端にフランジ状の鍔を設けたカラーを双方のケースの
取付部の孔に挿着し、該カラーにボルトを挿し込んで締

における取付部の座屈や破壊のおそれがなく、作業性も
向上する。As described above, the fixing structure of the electrical junction box of the present invention provides the mounting portions in both the upper case and the lower case, and forms a funnel-shaped opening in the hole of one of the mounting portions.
A collar provided with a flange-shaped flange at one end was inserted into the hole of the mounting portion of both cases, bolts were inserted into the collars and tightened, and the opening was funneled to the other end of the collar at the opening. Since the elastic portion caulking portion is formed and tightened and fixed, it is possible to increase the loosening torque while increasing the tightening force and protecting the mounting portion. Further, there is no possibility of buckling or breakage of the mounting portion at the time of tightening, and the workability is improved.
