Electrical plug-in connection, vehicle and method for locking an electrical plug-in connection

An electrical plug-in connection, comprising:

• a plug-in connector, the plug-in connector having,
• a guide means, and
• a tooth system;
• and
• a mating plug-in connector which can be connected to the plug-in connector, the mating plug-in connector having,
• a mating tooth system that corresponds to the tooth system of the plug-in connector, and
• an operating element that interacts with the guide means of the plug-in connector, and the operating element is movable between a home position and a locking position;
• and
• the plug-in connection and the mating plug-in connection, starting from an un-latched/preliminary latching position assume a latched/locking position as the operating element is moved from the home position to the locking position;
• and
• the tooth system and the mating tooth system are in engagement with one another when the operating element is in the locking position;
• and
• a plug-in connector body of the electrical plug-in connector, and the plug-in connector body is configured for receiving a contact device therein;
• and
• a shielding carried by the plug-in connector body;
• and
• the plug-in connector body is designed for insertion into an opening defined in a housing part of a housing of an electronics unit;
• and
• the plug-in connector body comprises an inner plug-in connector body and an outer plug-in connector body and the inner plug-in connector body and the outer plug-in connector body are positioned on opposite sides of the housing part;
• and
• the inner plug-in connector body can be secured in the housing of the electronics unit, independently of the housing part;
• and
• fastening means connect the inner plug-in connector body and the outer plug-in connector body to one another in such a way that the housing part is secured between the inner and outer plug-in connector bodies.

A vehicle, in particular a motor vehicle, comprising:

• an electrical plug-in connection, the electrical plug-in connection having,
• a plug-in connector, the plug-in connector having,
• a guide means, and
• a tooth system;
• and
• a mating plug-in connector which can be connected to the plug-in connector, the mating plug-in connector having,
• a mating tooth system that corresponds to the tooth system of the plug-in connector, and
• an operating element that interacts with the guide means of the plug-in connector, and the operating element is a lever and is movable in an arc of movement about two pivot axles carried on opposing exterior side portions of the mating plug-in connector and the lever operating element is movable between a home position and a locking position;
• and
• the plug-in connector and the mating plug-in connector, starting from an un-latched/preliminary latching position are moved into a latched/locking position responsive to the lever operating element moving in the arc of movement from the home position to the locking position;
• and
• the tooth system and the mating tooth system are in engagement with one another in the locking position of the plug-in connection;
• and
• teeth of the tooth system and teeth the mating tooth system are pushed axially one into the other in the plug-in direction responsive to the lever operating element moving from the home position to the locking position;
• and
• a housing for a high-voltage electronics unit, having a high-voltage battery, and the housing has a housing part to which the plug-in connection is secured.

A method for locking an electrical plug-in connection consisting of a plug-in connector and a mating plug-in connector, the method comprising the steps:

• providing a plug-in connector, the plug-in connector having,
• a guide means, and
• a tooth system;
• and
• providing a mating plug-in connector which can be connected to the plug-in connector, the mating plug-in connector having,
• a mating tooth system that corresponds to the tooth system of the plug-in connector, and
• an operating element that interacts with the guide means of the plug-in connector, and the operating element is a lever and is movable in an arc of movement about two pivot points carried an opposing exterior side portions of the mating plug-in connector and the lever operating element is movable between a home position and a locking position;
• and
• orienting the plug-in connector and the mating plug-in connector in a preliminary latching position, and in the preliminary latching position the guide means of the plug-in connector are positioned to interact with the lever operating element;
• moving the lever operating element of the mating plug-in connector through the arc of movement from the home position to the locking position;
• and
• the tooth system of the plug-in connector and the mating tooth system of the mating plug-in connector are brought into engagement with one another and into the locking position by the tooth system and the mating tooth system being pressed axially together one into the other responsive to the movement of the lever operating element from the home position into the locking position;
• and
• teeth of the tooth system and teeth the mating tooth system are pushed axially one into the other in the plug-in direction as the lever operating element is moved through the arc of movement from the home position to the locking position.
