と内壁４の接着面を密封する。A conventional waterproof connector of this type is shown in FIG. In the figure, 1 is a first housing,
It has an annular blind chamber 6 formed by an inner wall 4 that partitions a housing chamber 3 for the female terminal 2 and an outer wall 5 surrounding it, and an annular seal packing 7 is attached to the inner wall 4. Reference numeral 8 denotes a second housing, in which a housing portion 11 is provided in front of a housing chamber 10 for the male terminal 9.
has. Then, by fitting both housings 1.8, the sleeve part 11 is inserted into the blind chamber 6 and compresses the seal packing 7, so that the fitting surface of both housings and the seal packing 7 are
and the adhesive surface of the inner wall 4 is sealed.

A rubber stopper 14, 14' is attached to the crimping part with the connecting wire 13 to seal water from entering the housing chamber 3°10 from the wire side, and a terminal removal prevention member 15, 15' is attached to the rear end of the housing. It doubles as a preventive measure against terminal disconnection.
第６図のようにシールパツキン７を単に内壁４に外挿し

使用すると、水分浸入による電蝕などで機能が停止し、
大事故を引き起こすおそれがある。In a structure in which the seal packing 7 is simply inserted onto the inner wall 4 as shown in FIG. 6, when the housings 1 and 8 are separated, the packing is simultaneously pulled out by the separation force and separated from the inner wall 4. In the case of waterproof connectors used in complex and intricate areas such as engine compartments, it is difficult to detect such falling packing, and if the connectors are reattached and used in this state, they may stop functioning due to electrolytic corrosion caused by moisture intrusion. death,
There is a risk of causing a serious accident.
このような事態を防止するため、第７図ａのように、盲

も考案された。しかし、この場合には第７図すのように
プラスチック成形金型の合わせ目による段差１７が生じ
るために、防水性が極端に低下するという欠点があった
。In order to prevent such a situation, a means has been devised in which ribs 16 for preventing the gasket from coming off protrude from the inner wall 4 of the blind chamber 6, as shown in FIG. 7a. However, in this case, as shown in FIG. 7, a step 17 occurs due to the seam of the plastic molds, resulting in a disadvantage that the waterproof property is extremely reduced.
この欠点を改善するため、第８図のように、盲室６の底
壁１８側において内壁４にリブ１９を突設し、リブ１９
をシールパツキン７の内周に設けた溝２０に係合させて
パツキンを係止する技術が開示された（特開昭５８−１
８６１７８．実開昭６１−６０４７９号公報）。In order to improve this drawback, as shown in FIG.
A technique has been disclosed in which the seal packing 7 is engaged with a groove 20 provided on the inner periphery of the seal packing 7 to lock the seal packing (Japanese Unexamined Patent Publication No. 58-1
86178. Utility Model Application Publication No. 61-60479).
リブ１９を内壁４の底壁１８寄りに設ける理由は次のと
おりである。第８図において符号Ａで示され°るリブ１

段差１７ （第７図ｂ）が生じるから、この部分での防
水性は期待できない。防水性は、符号Ｂで示される第２
ハウジング８側のシールパツキン７と内壁４との接触面
に大きく依存する。もし、リブ１９が底壁１８から離れ
た位置にあると、Ｂ部分の長さが短くなり、防水性が低
下する。逆に、Ｂ部分を長くすると、シールパツキン７
の全長がいたずらに長くなり、パツキン自体の装着が困
難になる。The reason why the rib 19 is provided near the bottom wall 18 of the inner wall 4 is as follows. Rib 1 designated by the symbol A in FIG.
9 and the bottom wall 18, there is a step 17 (FIG. 7b) due to the joint of the mold as described above, so waterproofness cannot be expected in this area. Waterproofness is the second level indicated by the symbol B.
It largely depends on the contact surface between the seal packing 7 on the housing 8 side and the inner wall 4. If the ribs 19 are located away from the bottom wall 18, the length of portion B will be shortened and the waterproofness will be reduced. On the other hand, if you lengthen part B, the seal packing 7
The overall length of the package becomes unnecessarily long, making it difficult to attach the package itself.
従来公知技術では、シールパツキン７を盲室６に係止す
るためのリブ１９を盲室の底壁１８に近設して設ける必
要があるから、リブ１９と係合する溝２０もシールパツ
キン７の上下方向のどちらか一方に偏倚して設けること
になる。In the conventionally known technology, since it is necessary to provide the rib 19 for locking the seal gasket 7 to the blind chamber 6 near the bottom wall 18 of the blind chamber, the groove 20 that engages with the rib 19 is also attached to the seal gasket 7. It will be provided so as to be biased in either the vertical direction.

慮がなされるわけである。On the other hand, the production of wiring harnesses for automobiles and the like relies heavily on manual labor. The work of assembling connectors is no exception, and workers must assemble an extremely large number of connectors in a day. Therefore, work errors may occur, such as connecting the connector to other parts or fitting the connector in the wrong position. It is difficult to rely solely on the ability of workers who perform large-volume assemblies to reduce the number of incorrect assemblies, so careful consideration has been made to prevent reverse insertion of terminals and reverse insertion of connectors. That's why.

。Therefore, when assembling the waterproof connector, the groove 20 of the seal packing 7 is not symmetrical, so the operator must check the direction each time. is troublesome. In addition, parts such as the engine room require strict inspection.
Even in this inspection, it is difficult to judge at a glance whether the groove 20 and the rib 19 are securely engaged, and it is necessary to move the gasket once and insert it again, which significantly reduces the productivity of wire harnesses. This was a contributing factor.
