Electrical plug connector, electrical plug connection and securing element for an electrical plug connector

An electrical plug connection comprising:

• an electrical plug connector;
• and
• an electrical mating plug connector corresponding to the electrical plug connector;
• and wherein
• the electrical plug connector has a plug connector housing, a locking securement means for locking the electrical plug connector to the electrical mating plug connector, and a securing element which is displaceable between a pre-latching position and a securing position, whereat the securing element blocks the locking securement means in the securing position to prevent unlocking the electrical mating plug connector from the electrical plug connector;
• and wherein
• the plug connector housing forms a feed along which the securing element is displaceable into the pre-latching position starting from outside the plug connector housing in a direction towards the longitudinal axis (L) of the plug connector housing, and wherein
• the securing element has at least one guide pin which is engageable with the plug connector housing feed for displacing the securing element into the pre-latching position in order to guide the securing element during the displacement into the pre-latching position, and wherein
• the plug connector housing feed is in the form of one or more guide grooves which extend on an inner face of a side wall of the plug connector housing.

An electrical plug connector comprising:

• a plug connector housing, that defines a guide for guiding movement of a securing element, and a longitudinal axis (L);
• a locking securement means carried on the plug connector housing for locking the electrical plug connector to a corresponding electrical mating plug connector;
• and
• the securing element has a securing region at a front end portion, a support region at a rear end portion, and a spring region between the securing region and the support region, and the securing region faces the corresponding electrical mating plug connector, and the support region is opposite the front end portion along the longitudinal axis (L) of the plug connector housing when the securing element is inserted into the plug connector housing, and
• the securing element is displaceable between a pre-latching position and a securing position, and the securing element blocks the locking securement means in the securing position to prevent unlocking of the electrical plug connector from the corresponding electrical mating plug connector;
• and
• the securing element is positioned in the pre-latching position, in the plug connector housing, in such a way that the securing element is mechanically tensioned by insertion of the corresponding electrical mating plug connector into a pre-securing position, and wherein the guide defined in the plug connector housing guides displacement of the securing element from the pre-securing position into the securing position which releases the mechanical tension;
• and wherein
• the plug connector housing guide, guides the support region of the securing element in such a way that the support region performs a radial movement in the direction of the longitudinal axis (L) of the plug connector housing during axial displacement of the securing element from the pre-securing position into the securing position.
