The second connecting portion 76 and the plate-like member connecting portion 44 of the plate-like member 42 are disposed (see FIGS. 4 to 12).

  Further, when the housing unit 12 is inserted into the shell 90, the locking portion 28 formed on the first housing 14 of the housing unit 12 and the locking piece 118 formed on the shell 90 are locked and positioned. It becomes fixed.

  Furthermore, the notch portion 110 and the protruding portion 111 formed on the rear surface portion 108 of the shell 90 on the insertion port 106 side are fitted into the shell fitting portion 21 formed on the upper surface 20 of the first housing 14 for positioning. It becomes fixed.

  Further, since the O-ring 88 attached to the housing unit 12 is in close contact with the inner surface of the shell 90, the housing unit 12 is prevented from moving in the shell 90.

  Next, the reinforcing member 124 is attached to the shell 90. The reinforcing member 124 is attached to the shell 90 by the upper surface portion 92 side of the shell 90, the upper portion 126 of the reinforcing member 124, the rear surface portion 108 of the shell 90 and the rear portion 128 of the reinforcing member 124, and one side surface portion 112 of the shell 90. One side portion 138 of the reinforcing member 124 and the other side surface portion 114 of the shell 90 correspond to the other side portion 140 of the reinforcing member 124. Then, the reinforcing member 124 is moved downward from the upper surface portion 92 side of the shell 90, and the locking projection 116 formed on one side surface portion 112 and the other side surface portion 114 of the shell 90 and one of the reinforcing members 124 are The locking holes 136 formed on the side portion 138 side and the other side portion 140 side are locked.

  In the state where the locking protrusion 116 and the locking hole 136 are locked, the raised portions 120 formed on the one side surface 112 and the other side surface portion 114 of the shell 90 and the one side of the reinforcing member 124. Each welding protrusion 148 formed in the through-hole 146 part between the part 138 and the other side part 140 and each lead part 142 is arrange | positioned in the position which opposes (FIGS. 9-12). reference).

  Thereafter, the shell 90 and the reinforcing member 124 are fixed by welding the welded portion 143. As shown in FIG. 14, the welding is performed from the lower side of the raised portion 120 of the shell 90 and the welding projection 148 of the reinforcing member 124, that is, from the bottom surface 96 side of the shell 90 and the bottom portion 152 side of the reinforcing member 124. Is called. FIG. 14 shows the connector 10 upside down. In addition, since the base portion of the lead portion 142 of the reinforcing member 124 is welded to the shell 90 in the welding of the shell 90 and the reinforcing member 124, the shell 90 and the reinforcing member 124 can be fixed more firmly. Then, the assembly of the connector 10 is completed by fixing the shell 90 and the reinforcing member 124 by welding.

  In addition, the connector 10 of the embodiment is attached to the substrate (not shown) by connecting the first connection portion 50 of the first contact 46, the second connection portion 76 of the second contact 72, and a plate-like member to the contacts formed on the substrate. 42 plate-like member connecting portions 44 are attached by soldering or the like, and the lead portions 142 of the reinforcing member 124 are attached to the substrate by soldering or the like. At this time, the fixing portion 144 formed on the reinforcing member 124 comes into contact with a fixing hole or the like formed on the substrate, so that the fixing can be performed firmly (see FIGS. 11 and 12).

  In the embodiment, the housing unit is used. However, the housing unit is not limited to this, and a housing having a conventional contact mounted in the shell may be used. Further, in the embodiment, the raised portion for welding is formed on the shell. However, the present invention is not limited to this, and the conventional shell that does not form the raised portion is used to weld the reinforcing member having the weld protrusion. It may be.

  Moreover, although the case where the upper surface part side of the shell was covered was demonstrated the reinforcing member of embodiment, you may use the reinforcing member which covers not only this but the whole shell. Even in such a configuration, the deformation of the lead portion can be suppressed by welding the base portion of the lead portion of the reinforcing member and the shell.
