Electrical Connector Terminal Layout for Easier Grounded Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing and assembly of electrical connectors are complicated due to the numerous terminals that need to be precisely positioned and soldered, especially when dealing with wires that have metal shielding layers, which requires a grounding terminal with a lateral leg for connection.
Innovation Solution
The electrical connector design features a first terminal group and a second terminal group arranged on the same plane, with a connecting strip that electrically connects the second terminals and is grounded, allowing for staggered arrangement and batch manufacturing of second terminals, eliminating the need for lateral legs on each terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If terminals are arranged separately and soldered one by one, then each terminal can be precisely positioned, but the manufacturing process becomes complicated and time-consuming
Solution Approach 1:
The patent combines multiple second terminals into a single integrated structure where the second terminal body serves as both the terminal and the connecting strip. This merging eliminates the need for separate connecting strips and reduces the number of individual components that need to be positioned and soldered separately, thereby improving manufacturing efficiency while maintaining precise positioning through the integrated design.
Solution Approach 2:
The second terminal body is designed to serve multiple functions simultaneously: it acts as the terminal contact point, provides electrical connection between adjacent terminals, and serves as the connecting strip structure. This multi-functionality reduces the overall component count and simplifies the manufacturing process while ensuring precise electrical connections.
2Reliability
If lateral legs are added to grounding terminals for metal shielding layer connection, then proper electrical connection is achieved, but the device complexity increases
Solution Approach 1:
The patent merges the grounding terminal body and the connecting strip into a single integrated structure. The second terminal body itself serves as the connecting strip that provides both the terminal function and the electrical connection function, eliminating the need for separate lateral legs or additional connecting components. This reduces structural complexity while maintaining reliable grounding connections.
3Manufacturing precision
If numerous terminals are positioned one by one in the mold, then precise placement is achieved, but the manufacturing process becomes complicated
Solution Approach 1:
The patent merges adjacent second terminals into an integrated structure where the terminal body and connecting strip form a unified component. This reduces the total number of individual terminals that need to be positioned separately in the mold, simplifying the manufacturing process while maintaining precise placement through the reduced component count and integrated design.

AI summary
This disclosure is directed to an electrical connector having an insulative seat, a first terminal group and a second terminal group. The first terminal group has first terminals embedded in the insulative seat, the first terminals are separated from each other, and each first terminal has a first wiring end. The second terminal group is separated from the first terminal group, the second terminal group has second terminals and a connecting strip, the second terminals are embedded in the insulative seat, each second terminal has a second wiring end. The first and the second terminals are arranged on a reference plane, the first and the second terminals protrude from one side of the insulative seat, and the second terminals are bent to deviate from the reference plane, and the connecting strip is connected with the second terminals to make the second terminals be electrically connected with each other.
