Abstract: A shielding unit is formed by press-fitting a small diameter portion of a shielding shell into a shielding ring around which an end portion of a shielding member is wrapped, such that the end portion of the shielding member is sandwiched by the shielding ring and the small diameter portion. By having the end portion of the shielding member be folded over to the inside of the shielding ring when press-fitting the small diameter portion of the shielding shell into the shielding ring, even if the position of an opening is unknown, it is possible to reliably position the opening inside the shielding member, unexposed to the outside, after the press-fitting. This easily allows the end portion of the shielding member to be mounted and secured to the shielding shell so as not to be exposed to the outside.

Each fastener is a screw with a shank having a threaded front end that engages threads in the hole of the front fitting, and includes a screw head (214) at the rear of the shank which lies against a rearwardly-facing shoulder (172) on the rear fitting, to thereby prevent fitting separation. A bore (142) extends along the axis of the shank, and a rear end portion of the shank has a groove (182), resulting in a break-away portion of the fastener that has a ring-shaped cross-section. The ring-shaped coss-section permits tightening of the screw but results in the screw breaking when a predetermined force is applied to allow separation of the fittings.

The one piece shuttle mechanism includes a thrust bushing portion and one or more concentrically formed spring arms that are adapted to provide axial loading in the direction of an electrical connector shell when the backshell adapter assembly is assembled to an electrical connector.

Abstract: An electrical connector housing includes a lower shell, a connector block and an upper shell. An upper panel of the lower shell includes a first fixing mount and a draw hole, and the upper shell includes an outer side face having a second fixing mount. The upper panel of the lower shell has an inner face including a rib which is placed near the draw hole and extends towards the side panel of the lower shell while surrounding the draw hole. Likewise, the upper face of the connector block includes a pair of partition walls at a position corresponding to that of the rib, so that, when the connector block is inserted into the lower shell, the partition walls are closely superposed on the rib, and a draining space is formed away from a space for fixture ports for electrical parts, and leads to the drain hole. Such a configuration prevents the electrical connector housing from becoming too large and too costly. Such a housing structure also provides a better waterproofing quality.

Abstract: A device to join up cable sheathings comprises a chamber and a shaft. The shaft houses the cable and is connected in an electromagnetically impervious way to a rear part of the chamber. A front part of the chamber is itself designed to be connected in an electromagnetically impervious way to a casing, for example a connector casing. The conductive surface providing for the impervious electrical continuity between the periphery of the shaft and periphery of the chamber is outside the chamber. This makes it possible to give the internal diameter of the shaft a value that is substantially equal to that of a casing to which the front part of the chamber must be connected.
