Since the high-rigidity rib 37C and the side trunk rib 38B are formed, the stress is not concentrated in the vicinity of the body-side grounding portion 34, and the stress can be dispersed throughout the conductive plate main body 31. Moreover, since each rib is formed changing the height dimension and width dimension of each rib, the rigidity of each rib can be adjusted suitably.
- the connecting portions 32A for connecting the terminal connecting portions 32B are insert-molded inside the housing 40 so that the connecting portions 32A are covered with the resin of the housing 40, the terminal connecting portions 32B are attached to the housing 40. It can be held firmly. Further, since the connecting portion 32A is connected to the right edge of the conductive plate main body 31 via the stepped portion 36, the stress transmitted to the conductive plate main body 31 can be reduced by dispersing the stress in the stepped portion 36. Further, since the connecting portion 32A is configured to be connected to the right edge of the conductive plate main body 31 via the step portion 36, the stress applied to the connecting portion 32A can be distributed to the step portion 36. Furthermore, since the first rib group 37 is provided from the conductive plate body 31 to the stepped portion 36, the stepped portion 36 can be reinforced by the first rib group 37.
- ⁇ Other embodiments> The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.
- a plurality of ribs are provided in the above embodiment, according to the present invention, only one rib may be provided.
- it may be a tapered rib whose height gradually increases from the vicinity of the body side grounding portion 34 toward the outer peripheral edge of the conductive plate body 31, or from the vicinity of the body side grounding portion 34 to the outside of the conductive plate body 31. It is good also as a taper-shaped rib from which a width dimension becomes narrow toward a periphery.
- the conductive plate 30 is insert-molded in the housing 40, according to the present invention, the conductive plate is formed separately from the housing. You may make it assemble
- the conductive plate main body may be arranged behind the connecting portion without providing the step portion.
- the first rib group 37 is provided from the conductive plate body to the stepped portion in the above embodiment, according to the present invention, the first rib group may be provided only on the conductive plate body.

Abstract
Description
突部の高さ寸法は、ボディ側接地部に近い位置では低く、ボディ側接地部から遠い位置では高い構成としてもよい。
このような構成によると、突部の高さ寸法を調整することにより突部の剛性を適宜調整することができる。すなわち、突部の高さ寸法を高くすると、突部の高さ寸法が低い場合よりも剛性を高くすることができる。
このような構成によると、突部の幅寸法を調整することにより突部の剛性を適宜調整することができる。すなわち、突部の幅寸法を狭くすると、突部の幅寸法が広い場合よりも剛性を高くすることができる。
このような構成によると、導電板本体に複数のリブを設けることにより応力を分散させることができる。
このような構成によると、連結部がハウジングの樹脂で覆われることになるため、各端子接続部をハウジングに対して強固に保持することができる。
このような構成によると、連結部にかかる応力を段差部に分散させることができる。
このような構成によると、段差部を突部によって補強することができる。
本発明の実施形態を図1ないし図11の図面を参照しながら説明する。本実施形態におけるジョイントコネクタ10は、車両におけるワイヤハーネスの一部を構成している。すなわち、ワイヤハーネスは、複数本の電線によって構成されたワイヤハーネス本体と、ジョイントコネクタ10とを備えている。このうちワイヤハーネス本体を構成する電線には、複数本の第1アース用電線Wと、この第1アース用電線Wとは別の第2アース用電線(図示せず)とが含まれる。これらのアース用電線Wは、いずれも導体W1とこれを被覆する絶縁被覆W2とで構成され、ジョイントコネクタ10を介して車両のアース部位に一括して接続される。このアース部位は、図示はしないものの、車両のボディの壁面から内側に突設された接地ボルトによって構成されている。
本発明は上記記述及び図面によって説明した実施形態に限定されるものではなく、例えば次のような実施形態も本発明の技術的範囲に含まれる。
(1)上記実施形態では複数条のリブを設けているものの、本発明によると、1条のリブだけを設けてもよい。例えば、ボディ側接地部34の近傍から導電板本体31の外周縁に向けて高さ寸法が次第に高くなるテーパ状のリブとしてもよいし、ボディ側接地部34の近傍から導電板本体31の外周縁に向けて幅寸法が次第に狭くなるテーパ状のリブとしてもよい。
