Wedge Connector for Wide Cable Diameter Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wedge connectors are effective over a narrow range of relative cable sizes, requiring multiple different size connectors for various cable diameters in electrical distribution networks.
Innovation Solution
A wedge connector design featuring a C-shaped body member with inwardly facing channels and a wedge with concave surfaces and a spring rib, allowing for secure connection across a wider range of cable diameters without increasing connector thickness or material costs, using a single connector for diameters from 16 mm to 21 mm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single wedge connector design is used, then device complexity is reduced, but adaptability to different cable sizes deteriorates
Solution Approach 1:
The wedge connector employs adjustable parameters including spring rib deflection, channel extension length, and wedge geometry to accommodate different cable diameters (16mm to 21mm) within a single connector design, eliminating the need for multiple fixed-size connectors
Solution Approach 2:
The connector is designed as a universal multi-functional device that can securely connect cables across a broad diameter range through the combined action of the C-shaped body with extensions and the spring-loaded wedge mechanism, replacing the need for multiple specialized connectors
2Adaptability or versatility
If connector thickness is increased to accommodate larger cables, then adaptability improves, but material cost increases
Solution Approach 1:
Instead of increasing thickness in one dimension, the invention extends the channels rearwardly in a different dimension to provide accommodation for larger cables, maintaining material efficiency while expanding adaptability
Solution Approach 2:
The spring rib provides a dynamic, flexible component that can deflect to accommodate varying cable diameters, allowing the connector to adapt to different cable sizes without requiring increased overall thickness or additional material
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
Enables secure electrical and mechanical connection of cables across a broader diameter range, reducing the need for multiple connectors and maintaining material efficiency.
Implementation Method 1
The wedge has concave, outwardly facing surfaces on each side connected by a web extending between the sides and a spring rib formed in the wedge web. The spring rib extends continuously from the first wedge end toward the second wedge end opposite the first wedge end.

AI summary
A wedge connector for mechanically securing two electrical cables and making them electrically common is disclosed. The wedge connector has a C-shaped body member and a wedge. The body member has sides that converge toward a first body member end from a second body member end. The body member has edges that are formed to define a pair of inwardly facing channels connected by a web extending between the channels. The wedge also has converging sides to be conformably received in the C-shaped body member. The wedge has concave, outwardly facing surfaces on each side connected by a web extending between the sides. It also has a spring rib formed in the web that extends continuously from a first wedge end toward a second wedge end.
