FIG. 9A is a state before the seal member accommodating portion 335 is deformed, and FIG. The state at the time of high temperature (c) shows the state after the seal member accommodating portion 335 is deformed.

図9において、実施の形態に係る雌コネクタ11について説明したものと同一の機能を有する部位については共通する符号を付し、その重複した説明を省略する。   In FIG. 9, portions having the same functions as those described for the female connector 11 according to the embodiment are denoted by the same reference numerals, and redundant description thereof is omitted.

比較例に係る雌コネクタ11Aは、雌側ハウジング3Aにおける第3筒部33Aのシール部材収容部335Aの構成が、実施の形態に係る雌側ハウジング3における第3筒部33のシール部材収容部335の構成と異なる。   In the female connector 11A according to the comparative example, the configuration of the seal member accommodating portion 335A of the third cylindrical portion 33A in the female side housing 3A is the same as that of the seal member accommodating portion 335 of the third cylindrical portion 33 in the female side housing 3 according to the embodiment. The configuration is different.

より具体的には、シール部材収容部335Aは、図9(a)に示すように、内面335aの外面335bに複数の突部を有していない。したがって、シール部材収容部335Aとシールドケース5とは接触しておらず、シール部材収容部335Aとシールドケース5との間には空間が形成されている。   More specifically, the seal member housing portion 335A does not have a plurality of protrusions on the outer surface 335b of the inner surface 335a, as shown in FIG. Therefore, the seal member housing portion 335A and the shield case 5 are not in contact with each other, and a space is formed between the seal member housing portion 335A and the shield case 5.

例えば、雌コネクタ11Aをエンジンや電気モータ等の発熱源の近傍、すなわち高温環境下で使用した場合、図9(b)に示すように、シール部材収容部335Aは、シール部材13の膨張による応力を受けて第2筒部32側に向かって広がるように変形する。より具体的には、シール部材13はシール部材収容部335Aに接触する外周縁が長円形状であるため、第1〜第3の電線111〜113の並び方向に対して直交する方向(シール部材13の短手方向)に向かって膨張し易く、シール部材収容部335Aも当該方向に変形し易い。   For example, when the female connector 11A is used in the vicinity of a heat source such as an engine or an electric motor, that is, in a high temperature environment, the seal member accommodating portion 335A has a stress caused by expansion of the seal member 13, as shown in FIG. And is deformed so as to spread toward the second cylindrical portion 32 side. More specifically, since the outer peripheral edge of the seal member 13 that contacts the seal member accommodating portion 335A is oval, the direction perpendicular to the arrangement direction of the first to third electric wires 111 to 113 (the seal member 13 in the short direction), and the seal member accommodating portion 335A is also easily deformed in the direction.

その後、使用環境が常温に戻った場合、図9(c)に示すように、シール部材13は元の形状に戻ろうと収縮する。樹脂からなるシール部材収容部335Aは、その収縮率がシール部材13の収縮率に比べて小さい。これにより、変形したシール部材収容部335Aと収縮したシール部材13との間に隙間130が形成され、シール部材13のシール性が低下する。   Thereafter, when the use environment returns to room temperature, the seal member 13 contracts to return to the original shape as shown in FIG. The seal member accommodating portion 335A made of resin has a shrinkage rate smaller than that of the seal member 13. Accordingly, a gap 130 is formed between the deformed seal member accommodating portion 335A and the contracted seal member 13, and the sealing performance of the seal member 13 is deteriorated.

一方、実施の形態に係るシール部材収容部335では、図8に示すように、第1の突部331、第2の突部332、及び第3の突部333を第1〜第3の電線111〜113の並び方向(シール部材収容部335の長手方向)に沿って形成し、かつシールドケース5の内面5aに接触させることによって、シール部材13の膨張に対するシール部材収容部335の変形を低減する構造となっている。   On the other hand, in the seal member accommodating portion 335 according to the embodiment, as shown in FIG. 8, the first protrusion 331, the second protrusion 332, and the third protrusion 333 are replaced with the first to third electric wires. The deformation of the seal member accommodating portion 335 with respect to the expansion of the seal member 13 is reduced by forming along the arrangement direction of 111 to 113 (longitudinal direction of the seal member accommodating portion 335) and contacting the inner surface 5a of the shield case 5. It has a structure to do.

(実施の形態の作用及び効果)
以上説明した実施の形態によれば、以下のような作用及び効果が得られる。
(Operation and effect of the embodiment)
According to the embodiment described above, the following operations and effects can be obtained.

(1)シール部材13が収容されたシール部材収容部335は、シール部材収容部335を囲繞するシールドケース5と接触しているため、シール部材13の膨張によるシール部材収容部335の変形を抑えてシール部材13のシール性の低下を抑制することが可能である。 (1) Since the seal member accommodating portion 335 in which the seal member 13 is accommodated is in contact with the shield case 5 surrounding the seal member accommodating portion 335, deformation of the seal member accommodating portion 335 due to expansion of the seal member 13 is suppressed. Therefore, it is possible to suppress a decrease in the sealing performance of the sealing member 13.

(2)シール部材収容部335の第1〜第3の突部331〜333は、第1〜第3の電線111〜113の所定の並び方向に沿って形成されているため、断面長円形状又は断面楕円形状のシール部材13が膨張し易い第1〜第3の電線111〜113の並び方向に対して直交する方向(シール部材13の短手方向)におけるシール部材収容部335の変形を抑制することが可能である。 (2) Since the first to third protrusions 331 to 333 of the seal member accommodating portion 335 are formed along a predetermined arrangement direction of the first to third electric wires 111 to 113, the cross section is oval in shape. Or the deformation | transformation of the sealing member accommodating part 335 is suppressed in the direction (short direction of the sealing member 13) orthogonal to the arrangement direction of the 1st-3rd electric wires 111-113 in which the sealing member 13 with an elliptical cross section tends to expand. Is possible.

(3)シール部材13は、断面長円形状又は断面楕円形状を有しているため、第1〜第3の挿通孔131〜133(第1〜第3の電線111〜113)間の間隔を狭めることができ、シール部材収容部335の小型化につながる。 (3) Since the seal member 13 has an oval cross-section or an oval cross-section, the interval between the first to third insertion holes 131 to 133 (first to third electric wires 111 to 113) is set. This can be narrowed, leading to a reduction in the size of the seal member accommodating portion 335.
