Abstract

The electrical connector block comprises an insulating body and a plurality of conductor terminals mounted in it of which at least one is a protective conductor terminal. It is provided with an additional contacting member which passes through the base of the insulating body facing a connector block support and has at least one exterior plug which can directly make contact in a socket in the connector block support. The protective conductor plug can be mounted in the connector block during manufacture of the connector block or also subsequently to making the connector block without having to dismantle it. The structure and positioning of the protective conductor plug or plugs allows an easy automatic connection to the protective conductor by plugging the conector block into the connector block support.

Dependent claims

An electrical connector block assembly, comprising:

a connector block support formed with a plurality of openings at least one of which is a hole adapted to afford an electrical contact;
an insulating body formed with:
a plurality of conductor terminals for respective conductors,
means for mounting said body on said connector block support and including insulating plug members receivable in some of said openings, and
a protective terminal for engaging a further conductor and comprising a bent metal member in said body having an end bent away from a base of said body adapted to lie against said block support, and a recess formed in said member;
and
an additional contacting member for said protective terminal, formed in one piece from sheet metal, mountable on said body from the exterior of said base, and comprising:
a bend section projecting outwardly away from said base of said body and engaging in said hole of said block support to form an electrical connection therewith, said bend section having a pair of shanks separated by a bight,
a first connecting leg extending inwardly of said body from said base, said end of said bent metal member being braced laterally against said first connecting leg, and
a second connecting leg extending inwardly of said body from said base, spaced from said first leg, reaching through said recess and in electrical contact with said bent metal member at a location thereon spaced from said end.
