Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conductor connection technologies using spring force clamping lack versatility and efficient methods for securely clamping and releasing electrical conductors, particularly in compact designs.
Innovation Solution
A contact insert with a wedge-shaped contact frame and V-shaped clamping spring, featuring angled lateral walls, a securing tab, and actuation elements like pivotable levers or pushbuttons, allows for universal application in conductor connection terminals and assemblies with busbars, enabling secure clamping and easy release of electrical conductors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional spring force clamping system is used, then electrical conductors can be clamped, but the system lacks versatility and cannot be easily adapted to different applications
Solution Approach 1:
The contact insert is designed with a standardized contact frame and clamping spring assembly that can be universally applied in different conductor connection terminals and busbar assemblies. The modular design with standardized dimensions and mounting options enables the same basic structure to serve multiple functions and applications while maintaining simplicity through reuse of the core clamping mechanism
2Adaptability or versatility
If the contact insert is designed for universal application, then it can be used in various configurations, but the structural design becomes more complex
Solution Approach 1:
The contact insert is divided into distinct functional segments: a contact frame with lateral walls forming a receiving area, a separate clamping spring with contact arm and clamping arm, and optional actuation elements. This segmentation allows each component to be independently designed and manufactured with simple geometry, yet when assembled provides versatile functionality through different mounting configurations and actuation options
3Volume of moving object
If a compact design is used to improve space efficiency, then material usage is reduced, but the clamping mechanism becomes more difficult to operate
Solution Approach 1:
The clamping spring is designed with elastic properties that enable dynamic operation within a compact volume. The spring can be manually deflected to release conductors or actuated by external elements such as pivotable levers or pushbuttons. This dynamic mechanism allows full clamping and release functionality in a space-efficient design, maintaining ease of operation through simple mechanical action despite the compact form factor

AI summary
A contact insert for clamping an electric conductor to a clamping point by a clamping spring. The contact insert has a contact frame having at least one contact base and a respective lateral wall arranged at an angle to the contact base, wherein the lateral walls run substantially parallel to each other, and a receiving area is formed between the lateral walls. The clamping spring is arranged in the receiving area. The clamping spring has a contact arm, a spring bend, which adjoins the contact arm, and a clamping arm, which adjoins the spring bend. The contact arm is secured to one or both lateral walls or to at least one securing wall, which adjoins one or both lateral walls. The clamping arm is pretensioned relative to the contact base. The clamping point for the electric conductor to be clamped is formed between the clamping arm and the contact base.
