Electrical connection device

An electrical connection device, comprising:

• a first jaw having a first insertion surface introduced into a connection casing, the first insertion surface is substantially perpendicular to an insertion direction in which the electrical connection device is inserted into the connection casing;
• and
• a second jaw facing the first jaw in a closed state, the first jaw has a first surface facing the second jaw that is substantially parallel to the insertion direction and an opposite first surface opposite the first insertion surface, the first jaw has a first recess extending from a first edge formed by a junction between the first surface facing the second jaw and the first insertion surface at least partially into the first surface and toward the opposite first surface, the second jaw has a second surface facing the first jaw and extending substantially parallel to the insertion direction, a second insertion surface introduced over the connection casing and perpendicular to the insertion direction, and an opposite second surface opposite to the second insertion surface, the second jaw has a second recess extending from a second edge formed by a junction between the second surface facing the first jaw and the second insertion surface at least partially into the second surface and toward the opposite second surface, the first recess faces the second recess in the closed state, the first recess and/or the second recess has a rod at the first edge and/or the second edge, the first recess and the second recess are positioned on opposite sides of the rod in the closed state of the first jaw and the second jaw.

An electrical connection system, comprising:

• a connection casing having an opening and an electrical contact arranged in the opening, the electrical contact having a pair of branches forming a pincer;
• and
• a device including:
• a first jaw having a first insertion surface introduced into the connection casing, the first insertion surface is substantially perpendicular to an insertion direction in which the electrical connection device is inserted into the connection casing;
• and
• a second jaw facing the first jaw in a closed state, the first jaw has a first surface facing the second jaw that is substantially parallel to the insertion direction and an opposite first surface opposite the first insertion surface, the first jaw has a first recess extending from a first edge formed by a junction between the first surface facing the second jaw and the first insertion surface at least partially into the first surface and toward the opposite first surface, the second jaw has a second surface facing the first jaw and extending substantially parallel to the insertion direction, a second insertion surface introduced over the connection casing and perpendicular to the insertion direction, and an opposite second surface opposite to the second insertion surface, the second jaw has a second recess extending from a second edge formed by a junction between the second surface facing the first jaw and the second insertion surface at least partially into the second surface and toward the opposite second surface, the first recess faces the second recess in the closed state, the first recess and/or the second recess has a rod at the first edge and/or the second edge, the branches are inserted on either side of the rod in the first recess and the second recess during insertion of the device in the connection casing in the insertion direction through the opening.
