Solution Overview
Problem
Existing electrical connection terminals are bulky and cumbersome, making it difficult to easily insert and remove two conductors simultaneously, especially in the context of reducing device dimensions and improving connection efficiency.
Innovation Solution
A compact electrical connection terminal design featuring a current bar between two clamping legs, allowing parallel insertion and removal of conductors, with a single clamping spring and current bar arrangement, and an actuating button that opens both spring-loaded terminal connections simultaneously, reducing the terminal's overall dimensions and simplifying the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact terminal design with a single clamping spring and current bar is used, then the terminal dimensions are reduced, but it becomes difficult to insert and remove two conductors simultaneously
Solution Approach 1:
The single clamping spring is divided into two independent clamping legs that can move independently. Each clamping leg can be actuated separately by its own actuating button, allowing one conductor to be inserted or removed while the other remains connected. This segmentation enables simultaneous operation on both conductors while maintaining a compact terminal structure.
Solution Approach 2:
The clamping legs are designed with dynamic movement capability, allowing them to open and close independently through actuating buttons. This dynamic design enables the operator to selectively actuate one or both clamping legs, facilitating easy insertion and removal of conductors while maintaining compact dimensions.
2Ease of operation
If separate current bars and clamping springs are used for each conductor, then ease of operation is improved, but device complexity and dimensions increase
Solution Approach 1:
Two separate clamping spring assemblies are merged into a single integrated clamping spring with two independent clamping legs. This unified structure shares common components such as the spring body and mounting features, reducing overall part count and assembly complexity while maintaining independent operation capability for each conductor connection.
Solution Approach 2:
The single clamping spring serves multiple functions by providing two independent clamping legs, each capable of independently clamping a conductor. This multi-functional design eliminates the need for separate clamping spring assemblies, reducing structural complexity while maintaining ease of operation for both conductor connections.
3Ease of manufacture
If traditional terminal designs are used, then manufacturing simplicity is maintained, but connection efficiency and speed are reduced
Solution Approach 1:
The clamping legs are designed to be automatically actuated by the insertion or removal of conductors themselves. When a conductor is inserted, it automatically triggers the clamping leg to close and secure the connection. This self-service mechanism eliminates the need for separate manual actuation steps, significantly improving connection efficiency while maintaining manufacturing simplicity.
Solution Approach 2:
The actuating buttons are pre-positioned and spring-loaded to automatically open the clamping legs when pressed. This preliminary preparation of the actuation mechanism allows for rapid conductor insertion and removal without requiring complex manual manipulation, thereby improving connection speed and efficiency while keeping the manufacturing process simple.

AI summary
The electrical terminal (1) has a conductor connection arrangement having a current bar and a clamping spring made and arranged so that the current bar is located between the two clamping legs (8,9) of the clamping spring and running parallel to the insertion direction of connected conductors (6) in a terminal chamber (3). Each side of the current bar forms a spring force clamping terminal with the clamping leg.
