The rear surface portion 68 is formed so as to be higher. Further, the rear surface portion 68 side of the locking portion 84 is formed with a standing portion 85 that is erected substantially vertically, and the protruding portion 52 of the locked portion 48 formed on the housing 18 </ b> A is formed on the standing portion 85. It is designed to prevent the lock from being released by being caught and locked.

  Further, the locking portions 84 are respectively formed over a predetermined length along the width direction of the shell 62A, that is, the direction orthogonal to the direction in which the housing 18A is inserted.

  Further, the locking portion 84 is formed at a position where the sealing member 90 disposed between the housing 18A and the shell 62A is compressed in a state where the housing 18A is fixed, respectively. The position is such that there is no gap between.

  The locking portion 84 is formed, for example, by pressing from the upper surface portion 74A side and the bottom surface portion 76A side of the shell 62A. At this time, the upper surface portion 74A of the shell 62A in which the locking portion 84 is formed. In addition, the bottom surface portion 76A is formed so as not to have holes or cuts.

  Further, as shown in FIG. 9, a gasket 92 is provided on the outer peripheral surface surrounded by the upper surface portion 74A, the bottom surface portion 76A, the one side surface portion 78, and the other side surface portion 80 of the shell 62A, as in the first embodiment. Will be provided. The gasket 92 is made of a resin material, and is formed so as to be integrated with the shell 62A by molding, for example.

  Further, as in the first embodiment, the seal member 90 is formed in an annular shape by an elastically deformable resin material as shown in FIGS. 6 and 9B. Further, the seal member 90 can be attached to the outer peripheral side of the seal member holding portion 40 formed in the housing 18A, and has a size capable of coming into contact with the wall portion 72 of the rear surface portion 68 of the shell 62A. Is formed.

  Next, assembly of the connector 10A of the second embodiment will be described mainly with reference to FIGS. In the assembly of the connector 10A of the second embodiment, the housing unit 46A in which the contact 12 and the housing 18A are integrally formed, and the seal member 90 are inserted into the internal space 82 of the shell 62A in which the gasket 92 is previously attached to the outer periphery ( (See FIGS. 13A and 13B). As in the first embodiment, this insertion is performed by first inserting the seal member 90 from the opening 66 of the shell 62A, and then forming it on the connection portion 16 side of the contact 12 of the housing unit 46A, that is, the rear surface 24 of the housing 18A. The seal member holding part 40 is inserted into the inner space 82 of the shell 62 first from the side. Note that the seal member 90 may be inserted in a state of being attached to the seal member holding portion 40 of the housing 18A in advance. At this time, since the seal member 90 does not move while being in contact with the shell 62A when inserted, it is possible to suppress problems such as separation, deformation, and damage.

  Thereafter, when the insertion of the seal member 90 and the housing unit 46A is continued, as shown in FIG. 14A, the locked portion 48 formed on the upper surface 26A and the bottom surface 28A of the housing 18A and the inner upper surface portion 86 and the inner surface of the shell 62A, respectively. The locking portions 84 formed on the bottom surface portion 88 come into contact with each other. When further inserted from this state, as shown in FIGS. 14B and 14C, the protrusion 52 of the housing 18A gets over the locking portion 84 of the shell 62A, and the locking portion 84 of the shell 62A fits into the groove 50 of the housing 18A. In addition, the standing portion 85 of the locking portion 84 and the protrusion 52 of the locked portion 48 are locked. At this time, the inclined portion 54 formed in the locked portion 48 of the housing 18 </ b> A and the locking portion 84 of the shell 62 </ b> A formed in an inclined manner can be smoothly inserted. In addition, either or both of the housing 18A and the shell 62A may be elastically deformed.

  Further, in a state where the locked portion 48 of the housing 18A and the locking portion 84 of the shell 62A are locked, as shown in FIGS. 14B and 14C, the seal member 90 held by the seal member holding portion 40 of the housing 18A. Is compressed between the rear surface 24 of the housing 18A and the wall portion 72 of the rear surface portion 68 of the shell 62A. Therefore, as in the first embodiment, the gap between the housing 18A and the shell 62A is closed by the compressed seal member 90, so that functions such as waterproofing and dustproofing can be exhibited. Thus, the assembly of the connector 10A of the second embodiment is completed.

  In the first and second embodiments, the case where the contact 12 is provided only on the upper surfaces 26 and 26A of the housings 18 and 18A has been described. However, the present invention is not limited thereto, and the contact 12 is provided on the bottom surfaces 28 and 28A. The contacts may be provided in two rows.

  Moreover, you may make it attach the member for attaching to a board | substrate to the connectors 10 and 10A of Embodiment 1 and 2, for example to the shells 62 and 62A.
