Integrated-Stop Contact Piece for Controlled Conductor Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical contact devices lack a mechanism to prevent uncontrolled deep insertion of electrical conductors, which can lead to improper connections and potential damage.
Innovation Solution
An L-shaped main contact body with a bent-out stop piece and clamping devices limits the insertion depth of electrical conductors, featuring fastening means to secure the contact piece in a housing and prevent unintentional insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no stop mechanism is provided, then the contact piece allows free insertion of conductors, but uncontrolled deep insertion can occur leading to improper connections and potential damage
Solution Approach 1:
The stop piece is integrated directly into the contact piece body as a unified component, combining the contact function and stop function into a single element. This eliminates the need for separate stop mechanisms while maintaining connection reliability and preventing uncontrolled deep insertion.
Solution Approach 2:
The stop piece is pre-configured at a specific position on the contact piece to limit insertion depth before the conductor is inserted. This preliminary positioning ensures that the conductor cannot be inserted too deeply, preventing damage and improper connections from the outset.
2Ease of manufacture
If the contact piece structure is simplified for easy production, then manufacturing cost decreases, but the ability to prevent unintentional deep insertion may be compromised
Solution Approach 1:
The stop piece is formed as an integral part of the contact piece, merging two functions into one component. This integration simplifies manufacturing by reducing the number of parts and assembly steps while simultaneously ensuring reliable insertion control through the built-in stop mechanism.
Solution Approach 2:
The stop piece utilizes the existing structural parameters of the contact piece (such as wall thickness or protrusion dimensions) to create the stopping function. By leveraging existing geometric parameters rather than adding separate components, the design maintains manufacturing simplicity while achieving reliable insertion depth control.
