Electrical contact element

An electrical contact element including a base element ( 1 ) formed from a flat material with a high electrical conductivity and includes a conductor contact portion ( 2 ), a base portion ( 4 ) integrally connected to the conductor contact portion ( 2 ) and formed box-like defined by an upper wall ( 5 ) with an opening ( 6 ), a bottom wall ( 7 ) arranged opposite to the upper wall ( 5 ) and two side walls ( 8, 9 ) connecting the upper wall ( 5 ) and the bottom wall ( 7 ), and a flat terminal pin ( 16 ) integrally connected to the base portion ( 4 ) and extending away from the conductor contact portion ( 2 ) and having two vertically arranged pin portions ( 17 a , 17 b). The contact element also includes an elastic retaining element ( 18 ) formed from a sheet spring steel and including a flat pin-reinforcement portion ( 19 ) arranged between the two pin portions ( 17 a , 17 b), an intermediate portion ( 20 ) extending from the pin-reinforcement portion ( 19 ) and abutting an inner side of the bottom wall ( 7 ), and an elastic retaining portion ( 21 ) angled relative to the intermediate portion ( 20 ) and projecting out of the opening ( 6 ) and forming a support edge ( 23 ).
