Abstract
An electrical connector socket is provided, which has a locking device with which an electrical connector can be locked to the electrical connector socket when plugged in, wherein the locking device is arranged at least partly inside the electrical connector socket and protrudes at least partly from the electrical connector socket on the plug-in side. The electrical connector is provided for transmitting high currents and signals, wherein the electrical connector as a locking contour, into which a locking device of an electrical connector socket can engage, wherein the locking contour is arranged on the electrical connector on the plug-in side.
Claims22
An electrical connector socket comprising:
- a locking device configured to lock an electrical connector to the electrical connector socket when the electrical connector is plugged in to the electrical connector socket, wherein the locking device is arranged at least partly within the electrical connector socket and protrudes at least partly from the electrical connector socket on a plug-in side of the electrical connector socket, and wherein the locking device includes both an electromechanically actuated locking element that is displaceable between a locked configuration and an unlocked configuration and a manually actuated locking element that is displaceable between a locked configuration and an unlocked configuration, whereby the electrical connector can only be removed from the electrical connector socket when both the electromechanically actuated locking element and the manually actuated locking element are in their unlocked configurations.
An electrical connector socket comprising:
- a locking device configured to lock an electrical connector to the electrical connector socket when the electrical connector is plugged in to the electrical connector socket, wherein the locking device is arranged at least partly within the electrical connector socket and protrudes at least partly from the electrical connector socket on a plug-in side of the electrical connector socket,
- wherein the blocking element has two spring-supported blocking pins which each engage in a respective blocking opening assigned to each spring-supported blocking pin in the electrical connector, and wherein the two spring-supported blocking pins are aligned oppositely to each other and each molded on a respective base, wherein the bases are configured to be complementary to each other and are coupled to each other via a spring.
An electrical connector socket comprising:
- a locking device configured to lock an electrical connector to the electrical connector socket when the electrical connector is plugged in to the electrical connector socket, wherein the locking device is arranged at least partly within the electrical connector socket and protrudes at least partly from the electrical connector socket on a plug-in side of the electrical connector socket,
- wherein the locking device has a blocking element which has at least one spring-supported blocking pin, which engages in a blocking opening assigned to the spring-supported blocking pin in the electrical connector, and
- wherein the locking device has a movable locking slide which has a U-shaped fork an end thereof which blocks and releases the blocking element.
An electrical connector for transmitting high currents and signals, the electrical connector engageable with an electrical connector socket having a locking device that includes both an electromechanically actuated locking element that is displaceable between a locked configuration and an unlocked configuration and a manually actuated locking element that is displaceable between a locked configuration and an unlocked configuration, the electrical connector comprising:
- a locking contour in which the locking device of the electrical connector socket can engage, wherein the locking contour is arranged on the electrical connector on a plug-in side of the electrical connector, and
- a manually actuated element that is configured to move the manually actuated locking element of the locking device of the electrical connector socket to its unlocked configuration when the manually actuated element of the electrical connector is displaced by a user,
- wherein the electrical connector can only be removed from the electrical connector socket when both the electromechanically actuated locking element and the manually actuated locking element of the locking device are in their unlocked configurations.
A system comprising:
- an electrical connector socket;
- and
- an electrical connector,
- wherein the electrical connector socket includes a locking device configured to lock the electrical connector to the electrical connector socket when the electrical connector is plugged in to the electrical connector socket,
- wherein the locking device is arranged at least partly within the electrical connector socket and protrudes at least partly from the electrical connector socket on a plug-in side of the electrical connector socket,
- wherein the electrical connector includes a locking contour arranged on a plug-in side of the electrical connector to receive the locking device of the electrical connector socket when the electrical connector is plugged in to the electrical connector socket, and
- wherein the locking device includes both an electromechanically actuated locking element that is displaceable between a locked configuration and an unlocked configuration and a manually actuated locking element that is displaceable between a locked configuration and an unlocked configuration, whereby the electrical connector can only be removed from the electrical connector socket when both the electromechanically actuated locking element and the manually actuated locking element are in their unlocked configurations.
A system comprising:
- an electrical connector socket;
- and
- an electrical connector,
- wherein the electrical connector socket includes a locking device configured to lock the electrical connector to the electrical connector socket when the electrical connector is plugged in to the electrical connector socket,
- wherein the locking device is arranged at least partly within the electrical connector socket and protrudes at least partly from the electrical connector socket on a plug-in side of the electrical connector socket,
- wherein the electrical connector includes a locking contour arranged on a plug-in side of the electrical connector to receive the locking device of the electrical connector socket when the electrical connector is plugged in to the electrical connector socket, and
- wherein the electrical connector has an unlocking mechanism with which a U-shaped handgrip of the locking device is opened and which releases a mechanical blocking element of the locking device as a result.
A method for breaking an electrical connection between an electrical connector socket and an electrical connector, wherein in the plug-in state, at least one blocking pin of a locking device of the electrical connector socket latches into an associated blocking opening in a locking contour of the electrical connector, wherein the at least one blocking pin is blocked on the plug-in side via a U-shaped handgrip and wherein, as soon as a transmission of energy takes place, the at least one blocking pin is additionally blocked on a connection side by a U-shaped fork of the locking device, the method comprising:
- before a possible withdrawal of the electrical connector, checking, via an evaluation unit of the electrical connector socket, whether the electrical connection is voltage-free and, only when the electrical connection is voltage-free,
- moving the U-shaped fork into a release position,
- wherein the U-shaped handgrip is likewise moved into a release position by an unlocking mechanism integrated in the electrical connector, and
- wherein the electrical connection is then broken by the electrical connector being pulled out of the electrical connector socket.
