Patent ID: 7438587

Claim:
A multipolar electrical connector with spring contacts which has, for each conductor to be joined to the connector, a first aperture adapted to receive the conductor and a second aperture, parallel to the first aperture, adapted to receive an actuator pin which, by sliding in the second aperture according to its position, acts on a spring contact of the connector to lock the conductor to the connector or to release the conductor from the connector, wherein, when the conductor is locked in the connector by the spring contact, the corresponding actuator pin is inserted completely into the connector; and means adapted to retain the actuator pin in the second aperture of the connector, wherein said retaining means comprises a first pair of ridges present on side walls of an upper part of the second aperture and a second pair of ridges present on side walls of a bottom part of the actuator pin, said first and second pair of ridges engaging with each other to retain the actuator pin in the second aperture.
