AI Technical Summary

Technical Problem

Existing electrical contact elements, particularly end-contact elements, face challenges in achieving high mechanical stability while being cost-effective for mass production, as they are often designed as solid turned parts, leading to significant material and assembly costs, and are not suitable for end-face contacting.

Method used

The development of an electrical contact element formed from a stamped and bent part or deep-drawn metal component, featuring a contact area with a support region, which is connected monolithically to provide mechanical stability and reduce material and assembly costs, allowing for efficient production in mass quantities.

Benefits of technology

This solution enables the production of cost-effective electrical contact elements with high mechanical stability, suitable for end-face contacting, while minimizing material and assembly costs, and maintaining durability, making it suitable for applications like the automotive sector and electrical engineering.

Abstract

The invention relates to an electrical contact element (3) formed from a stamped and bent part or a deep-drawn metal component (1). The electrical contact element (3) has a contact area (6) with an end contact surface (7) designed for electrical and mechanical contact with an electrical mating contact element. The electrical contact element (3) also has a support area (8) arranged on a side of the contact area (6) facing away from the end contact surface (7) and designed to mechanically support the contact area (6). The contact area (6) is integrally connected to the support area (8) via a primary connecting section (9).
