Actuating Button Head Recess Design for Cable Terminal Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductor connection terminals often experience unreliable guidance of the actuating pusher when acted upon by an actuating tool, leading to potential misalignment and contact with terminal components, such as conductor rails.
Innovation Solution
The actuating button head features an indentation with increasing depth from the central area to the edge areas, incorporating sloping surfaces and a recess design that allows for angled tool insertion, ensuring the force is directed along the longitudinal axis, reducing tilting and jamming risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the actuating button head has a flat-bottomed recess for receiving the actuating tool, then the tool can be easily inserted, but the actuating button may tilt or hit components when the tool is applied at an angle
Solution Approach 1:
The recess bottom is designed with a curved surface featuring a central depression area and sloping edge areas. This curvature guides the actuating tool's force vector toward the longitudinal axis of the actuating button, preventing tilting and ensuring reliable actuation even when the tool is inserted at an angle.
2Reliability
If the actuating button is designed with precise guidance features, then the actuation reliability improves, but the device complexity increases
Solution Approach 1:
The guidance function is localized to the recess bottom surface geometry rather than requiring additional guidance components. The sloping edge areas and central depression area work together to guide the tool force, achieving reliable actuation through local surface characteristics rather than complex mechanical guidance systems.

AI summary
A conductor terminal (1) comprising an insulating housing (2), a clamping spring (3) for clamping an electrical conductor, and an actuating push button (10) is described. The actuating push button (10) is slidably mounted in the insulating housing (2) and has an actuating section (11) for applying pressure to the clamping spring (3) and an actuating push button head (18) accessible from the outside of the insulating housing (2), with a recess (19) for receiving an actuating tool (12). The recess (19) has a depth that increases from the central area (Z) to the outer areas (R).
