Electrical Connector Terminal Structure for High Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors have a large distance between terminals, leading to reduced terminal density and increased crosstalk interference when transmitting high-frequency signals due to the laterally protruding strip connecting portion.
Innovation Solution
A connecting structure with conductive terminals featuring a body, conducting portion, pre-breaking portion, temporary soldering portion, and elastic arms, where the temporary soldering portion is located between the elastic arms, reducing the distance between terminals and minimizing the facing area, thereby reducing crosstalk interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the terminals include a laterally protruding strip connecting portion for connecting a strip, then the terminals can be connected to the strip, but the distance between the terminals increases and the quantity of terminals per unit length decreases
Solution Approach 1:
The patent repositions the strip connecting portion from a lateral protrusion to a lower extension of the terminal body. This dimensional change allows the strip connecting portion to extend downward rather than sideways, reducing the lateral footprint and enabling higher terminal density while maintaining strip connection functionality.
Solution Approach 2:
Instead of having the strip connecting portion protrude laterally from the terminal body, the invention inverts the arrangement by extending it downward from the lower end of the terminal body. This inverted configuration achieves the same connection function while minimizing the distance between adjacent terminals.
2Ease of manufacture
If the terminals include a laterally protruding strip connecting portion, then the strip can be connected, but the facing area between terminals increases and crosstalk interference occurs
Solution Approach 1:
By moving the strip connecting portion to the lower end of the terminal body and extending it downward, the invention changes the spatial dimension of connection. This eliminates the lateral protrusion that creates large facing areas between terminals, thereby reducing capacitance and crosstalk while maintaining the strip connection function.
Solution Approach 2:
The invention extracts the strip connecting function from the main terminal body structure and separates it into a distinct lower extension. This separation allows the terminal body to have a more compact configuration, reducing the facing area between adjacent terminals and minimizing electromagnetic interference.
3Reliability
If the distance between terminals is large, then the terminals can be properly connected with gaps, but the quantity of terminals per unit length is small and materials are not saved
Solution Approach 1:
The patent utilizes the vertical dimension by extending the strip connecting portion downward from the terminal body, rather than using lateral space. This allows terminals to be positioned closer together horizontally while maintaining adequate connection gaps, thereby increasing terminal density and material efficiency without compromising connection reliability.
Solution Approach 2:
The invention inverts the conventional lateral connection approach by using a downward extension for strip connection. This inverted configuration enables better space utilization, allowing terminals to be arranged more densely while preserving the necessary connection gaps for reliable electrical contact.

AI summary
A connecting structure includes at least one conductive terminal having a body, a conducting portion connected below the body, a pre-breaking portion provided at an upper end of the body, and a temporary soldering portion connected above the pre-breaking portion; a first strip connected to the conducting portion; and a second strip soldered to the temporary soldering portion. A method for manufacturing an electrical connector includes: forming a first strip and at least one conductive terminal connected thereto; soldering a second strip to the temporary soldering portion of the conductive terminal; separating the conducting portion of the conductive terminal and the first strip; operating the second strip to control the conductive terminal to be mounted to a housing; and disconnecting the pre-breaking portion of the conductive terminal, and removing the second strip and the temporary soldering portion of the conductive terminal.
