Description

【考案の詳細な説明】本考案は例えば車体等の台座に例えば分岐接続
箱等の合成樹脂製ハウジングの取り付けるための
ハウジングの取付部の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a housing attachment portion for attaching a synthetic resin housing such as a branch junction box to a pedestal such as a vehicle body.

従来のこの種の台座にハウジングを取り付ける
部分の構成は第１図又は第２図の如きものであ
る。なおこれら第１，２図中１は台座、２は合成

えばゴム環状体等の緩衝材である。 The structure of a conventional part for attaching a housing to this type of pedestal is as shown in FIG. 1 or 2. In Figures 1 and 2, 1 is a pedestal, 2 is a synthetic resin housing, 3 is a mounting part integrally molded with the housing 2, 4 is a bolt, 5 is a nut,
6 is a washer, 7 is a spring washer, and 8 is a cushioning material such as a rubber annular body.

しかし、第１図のものはボルト締付時必要以上
の締付力をボルトに加えると衝撃力が取付部３に
作用し取付部が割れたりして破損し易い。又前記
破損を防ぐ為必要以上の締付力で締付けない様に
締付けトルクの管理および締付作業の丁寧さが必
要であつた。 However, in the case of the one shown in FIG. 1, if an excessive tightening force is applied to the bolt when tightening the bolt, an impact force acts on the mounting portion 3, and the mounting portion is likely to crack or be damaged. In addition, in order to prevent the above-mentioned damage, it is necessary to manage the tightening torque and carefully perform the tightening work so as not to tighten with more than necessary tightening force.

又第２図のものは第１図のものの問題点の解消
を目的として取付部３と台座１の間に緩衝材８を
介在させ、必要以上の締付力をボルトに加えた場
合、取付部３に作用する衝撃力を緩和させて取付
部３の破損を防止しているが部品点数の増加によ
るコストアツプとなる。 Also, in order to solve the problem of the one shown in Fig. 1, the one shown in Fig. 2 has a cushioning material 8 interposed between the mounting part 3 and the pedestal 1, so that if more than necessary tightening force is applied to the bolt, the mounting part Although damage to the mounting portion 3 is prevented by alleviating the impact force acting on the mounting portion 3, the cost increases due to an increase in the number of parts.

上記に鑑み本考案は案出されたものであり第１

る。 In view of the above, this invention was devised and is the first
This solves all of the drawbacks of the ones shown in Figures 2 and 2 at once. The present invention will now be described with reference to FIG. 3 as an example.

第３図に於いて第１図及び第２図と同一符号は

潰すのではなくへこませるものである。上記取付
部はその材質としてナイロンなどの弾性係数の大
きい剛性樹脂が例えば使用される。 In FIG. 3, the same reference numerals as in FIGS. 1 and 2 indicate the same parts. In the present invention, a protrusion 9 is provided on the side of the mounting portion 3 of the housing 2 that contacts the pedestal, and the back side of the protrusion 9 is hollowed out to form a cavity 10, so that the protrusion is crushed when tightening the bolt 4 and nut 5. It is something that makes a dent rather than a dent. For example, a rigid resin having a large elastic modulus such as nylon is used as the material for the mounting portion.

出来る。 According to the present invention, when the bolt is tightened, the protrusion 9 first comes into contact with the surface of the pedestal 1, and when the bolt is further tightened, the protrusion 9 is recessed into the cavity 10 without being crushed. Since the wall in contact with the base 1 on which the protrusion 9 is provided by the hollow portion 10 is given flexibility, the protrusion 9 is elastically depressed. Therefore, since the protrusion 9 has a buffering function to reduce the impact force acting on the mounting part 3 when the bolt 4 is tightened, the mounting part 3 may be damaged even if the bolt 4 is tightened with more than necessary tightening force. do not have. Furthermore, since the structure described above can be made at the same time as molding, it is possible to prevent an increase in cost without increasing the number of parts.

Claims

[Scope of utility model registration request]

It is a mounting part that is integrally molded with a synthetic resin housing, and has a protrusion on the side that contacts the pedestal, and a hollow part on the back side, so that when it is tightened to the pedestal, the protrusion is elastic rather than crushed. The mounting part of the synthetic resin housing is recessed.
