Connector, connection assembly and connection group

Connection assembly comprising:

• a connector for connecting at a proximal end of the connector along a connection direction, the connector including a contact element at a contact section, a base section, and an arm extending from the base section substantially along the connection direction to the proximal end, the arm includes at least one securing element for securing the connector from movement along the connection direction, the arm includes a lateral guiding face for guiding the securing element in a lateral direction transverse to the connection direction, wherein the base section is located closer to a distal end of the connector than the contact section, the distal end being opposite to the proximal end along the connection direction;
• and
• a mating connector arranged behind a bulkhead and accessible through a receptacle of the bulkhead, the mating connector mated to the proximal end of the connector when the proximal end of the connector passes through the receptacle in the bulkhead, the mating connector including a mating contact element configured to be mated to the contact element of the connector, the mating connector including a mating counter lateral guiding face configured to interface with the lateral guiding face;
• wherein in a pre-mounting state, in which the connector and the mating connector are spaced from each other along the connection direction, a distance between the at least one lateral guiding face and the mating counter lateral guiding face is smaller than a distance between the contact element and the corresponding mating contact element.

Connection group comprising:

• a connection assembly including a connector and a mating connector, a proximal end of the connector being mated with the mating connector along a connection direction the mating connector including a mating contact element, the connector including a contact element at a contact section configured to be mated with the mating contact element, a base section, and an arm extending from the base section substantially along the connection direction to the proximal end, the arm includes at least one securing element configured to be mated directly to the mating connector for securing the connector to the mating connector and preventing movement along the connection direction away from the mating connector, the arm includes an actuation section, the securing element being transferable from a securing state to a release state by an actuation at the actuation section, the actuation section being accessible from an outside of the connector, wherein the base section is located closer to a distal end of the connector than the contact section, the distal end being opposite to the proximal end along the connection direction;
• and
• a bulkhead including a receptacle, the connection assembly being located in the receptacle of the bulkhead with the mating connector arranged behind the bulkhead and accessible through the receptacle of the bulkhead, wherein the at least one securing element of the arm is mated with the mating connector when passed through the receptacle in the bulkhead, the actuation section being accessible through an opening of the receptacle.
