Wiring Connector Separate Wire Insertion Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing board-mounted wire connectors, especially those of the pluggable type, often face issues with reduced conductivity and wire retention due to wires resting on top of each other, leading to loose connections, particularly with thicker wire insulations and larger gauges, making secure connections difficult.
Innovation Solution
A fixed-mounted or pluggable wiring connector design that allows separate wire insertions along the same axis, secured by a single screw, featuring separate wire openings, a conductive U-shaped terminal, a clamping screw, a wire clamp, and a spring for enhanced pressure, ensuring secure and easy connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If two wires are inserted into a single port on the connector, then the connector width is reduced, but the connection security and conductivity deteriorate
Solution Approach 1:
The single port is segmented into two separate ports, allowing each wire to be inserted individually. This segmentation resolves the contradiction by providing separate insertion paths that improve connection security while maintaining a compact overall connector structure through the shared body design.
Solution Approach 2:
The connector utilizes the depth dimension by allowing wires to be inserted through separate ports that are positioned at different locations but terminate at the same terminal contact point. This dimensional arrangement enables secure individual wire insertion while keeping the connector's footprint compact.
2Device complexity
If two wires rest on top of each other at the same connection point, then the connector structure is simplified, but the wire retention capability and conductivity are reduced
Solution Approach 1:
The terminal contact point is segmented into two separate contact surfaces within the same terminal body. Each wire contacts its own dedicated surface, preventing the wires from resting on top of each other and ensuring individual clamping force application, which improves wire retention while maintaining structural efficiency.
Solution Approach 2:
The terminal body acts as an intermediary structure that receives both wires through separate ports and provides dedicated contact surfaces for each. This intermediary design allows the connector to maintain simplicity while ensuring each wire has its own retention path, preventing the wires from interfering with each other's clamping.
3Device complexity
If a single screw secures both wires in one opening, then the clamping force distribution is simplified, but the connection reliability deteriorates with thicker wire insulations and larger wire gauges
Solution Approach 1:
The clamping mechanism is segmented so that the single screw applies force that is independently distributed to two separate wire contact points within the terminal. This segmentation allows each wire to receive adequate clamping force independently, resolving the issue of insufficient clamping for thicker insulations and larger gauges while maintaining a simple single-screw operation.
Solution Approach 2:
The terminal body merges the function of securing two separate wires into a single integrated component. The unified terminal structure with two contact surfaces allows one screw to effectively clamp both wires simultaneously, combining the security of separate clamping points with the simplicity of a single fastening operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a more secure and easier method for connecting wires, minimizing the risk of loose connections and improving conductivity by allowing individual wire insertions and applying appropriate clamping pressure, suitable for small form factor connectors.
Implementation Method 1
a spring form inside the U-shape of the fixed terminal that biases the U-shape outwardly and provides a level of pressure on an inserted wire so as to insure proper electrical connection between the wires and the fixed terminal
Implementation Method 2
tightening the clamping screw through a top hole of the nonconductive housing so as to apply appropriate clamping pressure on the fixed terminal and each wire via the wire clamp

AI summary
A small form factor wiring connector provides a two wire to two point connector with separate-hole insertion for two wires, by having two holes on the first casing side of the connector and a terminal connection on the opposite second side of the connector. The design works well for a pluggable or fixed-mounted connector. The separate wire insertion holes and the internal screw-driven clamping means with U-shaped wire clamp and U-shaped fixed terminal surfaces provides positive connections which will not easily loosen.
