Abstract: An electric plug connector includes a guide sleeve, a plug connector part attachable to the guide sleeve, a bayonet ring on the connector part for rotatably engaging with the guide sleeve to move between unlocked and locked positions, and a locking button arranged on the bayonet ring to slide with the ring as the ring moves. While the connector part is attached to the guide sleeve the ring locks the attachment by engaging with the guide sleeve when the ring is in its locked position. The button is displaceable relative to the guide sleeve between inactivated and activated positions. The button includes a latching hook and a pin that interact with the sleeve to enable the button to move between its inactivated and activated positions. The latching hook and the pin engage with the sleeve when the button is in its activated position to secure the locking of the attachment.

Abstract: An electrical connector includes two connector parts each having a high-load (“HL”) housing with an HL contact and a low-load (“LL”) housing with a LL contact. One LL housing is movable relative to the other LL housing. The parts are movable to join and separate from one another. The HL housings join upon the parts joining such that the HL contacts join and establish a HL connection. The LL housings join after the one LL housing moves toward the other LL housing while the parts are joined such that the LL contacts join and establish a LL connection. The LL connection is prevented from being established until the HL connection is established as the LL housings are prevented from joining until the HL housings join. The HL connection is prevented from separating until the LL connection is separated as the HL housings are prevented from separating until the LL housings separate.
