Abstract: A multipolar electrical connector with spring contacts has, for each conductor to be joined to the connector, a first substantially cylindrical aperture adapted to receive the conductor and a second aperture, parallel to the first aperture, adapted to receive an actuator pin which, 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 it from the connector. When the conductor is blocked in the connector by the spring contact, the actuator pin is inserted completely into the connector.

Abstract: An electrical connector element (1) includes a connector body (2) wherein contact housings (20) are formed, electrical contacts (4) crimped to respective electrical cables (8) and able to be housed in the contact housings (20) of the connector body (2) and locking elements (5) designed to be fixed in the connector body (2) after insertion of the contacts (4). The locking elements (5) include stops (55), which protrude into the contact housings (20) so as to prevent the contacts (4) from coming out of their housings.

Abstract: The inventive apparatus has two plastic supports (2) mounted, in registrer with the top and bottom sides of the yoke body (1), and crown (1a), in which they are structurally incorporated. Preferably, the plastic supports are rectangular with rounded edges. Each support has hooks (3) to receive the compensation coils which are snap-fitted thereon. Also, each support has pins (5) for fastening the coil terminals 4a, 4b. The pins also support a damping cell when required. The cell includes a registor (6) connected in series with a capacitor (7). The compensation coils (4) can have a variable number of turns, depending upon the compensation which it is to achieve.
