Joint Connector Terminal Layout for Flexible Circuit Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional joint connectors require multiple short bars and caps for different circuit patterns, leading to increased material usage, additional processes, and higher costs and weight.
Innovation Solution
A joint connector design that eliminates the need for short bars and caps by using a housing with insertion holes and terminals, where leaf springs replace short bars, allowing for various patterns through terminal orientation changes, reducing material and labor costs while enabling flexible pattern configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If short bars and caps are used for different circuit patterns, then circuit connectivity is achieved, but material usage increases and weight increases
Solution Approach 1:
The housing is designed with multiple insertion holes that can accommodate different terminal configurations. The same housing structure serves multiple circuit patterns by varying only the terminal insertions, eliminating the need for separate caps and short bars for each pattern. This universal design reduces overall weight while maintaining circuit connectivity.
Solution Approach 2:
The cap and short bar components are merged into an integrated terminal structure. The terminals are directly inserted into the housing, combining the functions of electrical connection and structural support that were previously separated into multiple components. This integration eliminates redundant materials and reduces weight.
2Reliability
If short bars and caps are used for different circuit patterns, then circuit connectivity is achieved, but manufacturing complexity increases
Solution Approach 1:
A single housing design with standardized insertion holes serves all circuit patterns. The manufacturing process requires only varying the terminal configurations inserted into the same housing, rather than manufacturing different caps and short bars for each pattern. This significantly simplifies the manufacturing process and reduces complexity.
Solution Approach 2:
The connector is segmented into modular terminals that can be independently inserted and configured. This allows different circuit patterns to be achieved by simply reconfiguring which terminals are inserted into which holes, rather than manufacturing entirely different components for each pattern.
3Reliability
If short bars and caps are used for different circuit patterns, then circuit isolation is achieved, but device complexity increases
Solution Approach 1:
The housing includes partition walls that segment the internal space into isolated compartments. These partition walls provide circuit isolation between different terminals without requiring additional caps or complex external structures. The isolation is achieved through simple internal partitions integrated into the housing design.

AI summary
A joint connector includes a housing comprising a plurality of insertion holes. A first isolation terminal is inserted into a first insertion hole of the plurality of insertion holes. The first isolation terminal is configured to block current flow. A connection terminal is inserted into a second insertion hole of the plurality of insertion holes. The second insertion hole is adjacent to the first insertion hole and is electrically connected to the first isolation terminal.
