AI Technical Summary

Technical Problem

Existing electrical connectors in the automotive industry face challenges in achieving robustness, durability, and ease of assembly while maintaining compact size and economic production, with current fastening technologies like interference fits and spring tabs leading to damage and loose connections under tensile forces.

Method used

An electrical connector design featuring a fastening tab that can be bent from a resting to a fastening state, securely locking the insulating housing assembly to the outer conductor assembly, with positive blocking along translational and rotational degrees of freedom, using an undercut mechanism to prevent disconnection.

Benefits of technology

The design provides a robust and durable connector that withstands tensile forces, avoids damage to the housing, and facilitates easy assembly, suitable for high-performance automotive applications.

Abstract

The invention relates to an electrical connector (1) comprising an electrically insulating housing assembly (2) and an outer conductor assembly (3) positively connected to the housing assembly (2). The outer conductor assembly (3) has at least one fastening tab (8) that can be bent from a resting state to a fastening state. It is provided that the outer conductor assembly (3) is received in the housing assembly (2) such that the housing assembly (2) positively blocks relative movement between the outer conductor assembly (3) and the housing assembly (2) along a first translational degree of freedom (x) and / or along a second translational degree of freedom (y).In the basic state, the fastening tab (8) allows an assembly movement for mounting the housing assembly (2) on the outer conductor assembly (3) along a third translational degree of freedom (z) and, in the bent fastening state, positively locks the housing assembly (2) on the outer conductor assembly (3) at least along the third translational degree of freedom (z).
