ABSTRACT:
This terminal is consisting of two elements, one of which is formed by a metal coupling mechanism (1) a first ring (2) connected to the coupling mechanism (1) and a second ring (6) connected to the first ring (2) by means of a narrow lower link (5), so that the second ring (6) is externally projecting beyond the first ring (2), whereas the other element is formed by a hollow, tubular insulating envelope or sleeve internally featuring various subsequent shapes, i.e. a flaring or bellmouth (8) forming an initial step (9), followed by an annular recess (10), a second step (11) almost centrically located with respect to a cylindrical end section (12), so that the terminal to be used by the operator is obtained by introducing the second ring (6) in the sleeve (7) until it is positioned in the annular recess (10) and resting against the first step (9). After connection to the lead by crimping the first ring (2), the sleeve is moved axially so as to uncover the coupling zone, i.e. until the second ring fits into the end portion of the sleeve against the second step (11).
