Electrical Connector Gap Between Connecting Member and Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face issues with high-frequency signal transmission due to increased characteristic impedance caused by auxiliary supporting legs, which affect the connection between terminal strips and insulating bodies, leading to reduced transmission rates.
Innovation Solution
An electrical connector design featuring a connecting member embedded between the insulating body and terminal edges, with a gap between the connecting member and the terminal, ensuring the connector's structure does not increase terminal width and maintains high-frequency performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If auxiliary supporting legs are added to strengthen fixation between terminal strip and insulating body, then connection firmness is improved, but terminal width increases and characteristic impedance changes, reducing transmission rate
Solution Approach 1:
The patent removes the auxiliary supporting legs from the terminal structure and instead uses the insulating body itself to provide support and fixation. The insulating body is designed with an integrated support structure that eliminates the need for separate supporting legs, thereby maintaining terminal width and characteristic impedance while still providing firm connection.
Solution Approach 2:
The patent combines the support function with the insulating body by designing the insulating body to include integrated support structures. This merging of functions eliminates the need for separate auxiliary supporting legs, avoiding the problem of increased terminal width and characteristic impedance changes.
2Stability of the object's composition
If auxiliary supporting legs are connected to outermost terminals, then fixation is strengthened, but terminal width effectively increases, increasing characteristic impedance value
Solution Approach 1:
The patent extracts the support function from separate auxiliary legs and integrates it into the insulating body structure. This eliminates the need for additional components attached to terminal edges, thereby maintaining precise control over terminal width and characteristic impedance while still achieving stable fixation.
Solution Approach 2:
The insulating body is designed to serve multiple functions: electrical insulation, mechanical support, and structural stabilization. By making the insulating body multi-functional, the patent eliminates the need for separate auxiliary supporting legs, thereby maintaining manufacturing precision and characteristic impedance control.
3Ease of manufacture
If terminal strip is embedded in liquid insulating material, then insulating body formation is achieved, but terminal strip deviates from preset position, causing not firm connection
Solution Approach 1:
The patent incorporates support structures into the insulating body design before the embedding process. These pre-designed support structures provide positional guidance and mechanical constraint during the injection molding process, preventing terminal strip deviation and ensuring accurate positioning while maintaining ease of manufacture.

AI summary
An electrical connector and a method of manufacturing the same are provided. A connecting member is embedded in an insulating body between a side edge of the insulating body and an outer side of a first terminal or a last terminal in a first terminal group, and a gap exists between the connecting member and the first terminal or the last terminal. In other words, the connecting member is not in contact with the first terminal or the last terminal adjacent to the connecting member. Thus, the width of the first terminal or the last terminal is not increased, ensuring the high-frequency transmission rate of the first terminal group, and thereby forming an electrical connector which is capable of facilitating machining without affecting the transmission quality of the terminals, and having a stable structure and high-frequency transmission performance.
