A metal shield for a plug connection

摘要

The plug connection comprising an elastomeric shroud has a plug-receiving portion through which is connected a spark plug (5) comprising an hexagonal handling nut (5c). A metal shield comprising a top cover portion (11a) and two side-shield portions (11b, 11c) covers the elastomeric shroud. When mounted, the side-shield portions surround the plug-receiving portion and form joint seam zones (11d, 11e) having a bottom end and a top portions. The bottom portion includes an opening (11f) and a corresponding tab (11g). The side-shield portions further comprise flanges (11k, 11m). When the spark plug is connected to the plug connection, the flanges fit onto the hexagonal handling nut and the opening and tab are loosely fitted, so that the joint seam zones can be enlarged. Preferably, the top portion contains protrusions (11i, 11j) provided on the side of the side-shield portions and a corresponding recess (11h) provided on the side of the top shield, these protrusions and recess being also fitted when the shield is mounted. <IMAGE>
