<p>The fastener secures plug connectors on module support racks, or withdrawal frames for switchgear boxes etc. The plug connector is supported by protrusions on the front ends on perforated rails of the support racks etc. and held there by clamps. Each protrusion (4) has a firmly-connected plug stud (5) on the side facing the perforated rails, the stud being insertable into the rail perforations. To each protrusion is allocated a spring elastic spreading strip (6), which is fitted to the plug connector body (3') and engages resiliently the rear side of the perforated rail. Pref., each protrusions has two studs so spaced as to correspond to the span of three perforations in the rail. Between the two studs may be provided a fastening hole (7). The strip sides, away from the plug connector body, may be in the form of abutting surfaces.</p> |
