ング３を挿着係止する構造である。 The conventional locking structure of the waterproof seal ring in the waterproof connector described above is classified into four types as shown in FIGS. 1A to 1D. That is, in Figure A, a seal ring 3 is fitted to the stepped portion at the front end of a female connector housing 1 (hereinafter simply referred to as the female housing), and a presser member 4 is further fitted to the front end of the female housing 1 to prevent the seal ring 3 from falling off. It is attached and then connected to a male connector housing 2 (hereinafter simply referred to as male housing 2). Further, in FIG. B, a ring groove 5 of the seal ring 3 is formed near the front end of the female housing 1,
The seal ring 3 is fitted into the ring groove 5. In addition, the male housing 2 shown in FIG.
The front half 2'' of the male housing 2 is brought into contact with the outer peripheries of the two, and the outer peripheries of both are welded to lock and fix the seal ring 3. In addition, as shown in FIG.
The structure is such that the seal ring 3 is inserted and locked between the locking protrusion 9 and the bottom of the recess 7.
以上の従来の係止構造は、それぞれ下記の難点

ない等の一長一短がある。 That is, the structure shown in FIG. A has a large number of parts, resulting in high cost, and requires a large number of man-hours since the holding member 4 must be fixed by welding or the like. In addition, in the structure shown in Figure B, it is necessary to mold the ring groove 5 integrally with the female housing 1 using a mold that is divided into upper and lower halves, so there is no burr on the parting line where the upper and lower molds join. Occurrence is unavoidable and reduces sealing performance. Further, the structure shown in the drawing C is larger than the above-mentioned A and B, and requires welding equipment such as an ultrasonic welding device, resulting in high cost and lack of practicality. Furthermore, in the structure shown in FIG. When the seal ring 3 is attached or detached, the seal ring 3 may turn over or come off due to the insertion/removal resistance. Furthermore, since the seal rings 3 of the above A and B have an open structure that is externally fitted onto the female housing 1, they are likely to come into contact with other members and be damaged, and the above C and D have the seal ring 3 Although the built-in seal ring 3 is useful for preventing external injuries, it has advantages and disadvantages, such as the fact that the presence or absence of the seal ring 3 cannot be confirmed externally.
