AI Technical Summary

Technical Problem

Existing electrical connectors for motor vehicle safety restraint systems, particularly ignition charge connectors, face challenges in ensuring reliable connection and compactness due to the requirement for locking springs that interfere with standardized dimensions, leading to issues with force distribution and potential short circuits.

Method used

The design incorporates a pressure element with a central axis collinear to the housing's insertion section, a connector position assurance element (CPA) that slides into a locked position, and a cover to enclose the components, ensuring uniform force distribution and preventing short circuits, while allowing for compact dimensions.

Benefits of technology

This design results in a more stable, reliable, and compact electrical connector that prevents short circuits and withstands shocks and vibrations, using a collinear pressure element arrangement and insulating materials to enhance safety and efficiency.

Abstract

Electrical connector, in particular an ignition charge connector for a safety restraint system of a motor vehicle, for connecting to a mating electrical connector in one plug-in direction, wherein the electrical connector comprises: a case (12), wherein the housing (12) comprises an insertion section (22) that can be inserted into the electrical mating connector along the insertion direction (D), wherein the insertion section (22) has at least one receptacle (26) for receiving at least one electrical contact of an electrically conductive terminal, and a pressure element (18) arranged in the housing (12) such that the pressure element (18) can be compressed along the insertion direction (D), and a connector position assurance element (CPA 16) that can be moved from an unlocked position to a locked position along the insertion direction (D), wherein the locked position of the CPA (16) enables the electrical connector to be locked to the mating connector when the electrical connector is connected to the mating connector, characterized in that a central axis (C3) of the pressure element (18) is collinear with a central axis (C1) of the insertion section (22) of the housing (12) in the insertion direction (D).
