Electrical Connector Separated Conductive Terminal Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors with conductive terminals have a large volume due to the need for a strip connecting portion, which increases the space required and limits the miniaturization of electronic elements.
Innovation Solution
The electrical connector design features separately formed upper and lower connecting members that extend side by side within the same accommodating hole, reducing the overall space occupied by the conductive terminal and enhancing the insertion depth and stability of the connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a strip connecting portion is reserved on the conductive terminal to be connected to the strip, then the conductive terminal can be assembled to the plastic body through the strip, but the volume of the conductive terminal increases
Solution Approach 1:
The patent extracts the strip connecting portion from the conductive terminal structure, making them separate components. The conductive terminal no longer includes the strip connecting portion, allowing the terminal to be smaller while still enabling assembly through the strip. This resolves the contradiction by removing the unnecessary volume from the terminal itself.
Solution Approach 2:
The patent segments the assembly into separate components: the conductive terminal and the strip are formed separately and then assembled together. This segmentation allows each component to be optimized independently - the terminal can be minimized in volume while the strip provides the connecting function.
2Ease of manufacture
If a relatively large accommodating hole is provided on the plastic body to accommodate the conductive terminal with strip connecting portion, then the terminal can be assembled, but the volume of the entire electrical connector increases
Solution Approach 1:
By extracting the strip connecting portion from the terminal structure, the patent enables a smaller accommodating hole in the plastic body. The terminal can be inserted through a reduced opening since it no longer requires space for the integrated strip connecting portion, thus reducing the overall connector volume.
Solution Approach 2:
The segmented design where the strip and terminal are separate components allows for a more compact accommodating hole structure. The hole only needs to accommodate the terminal portion, while the strip connects from the outside, enabling a smaller overall connector footprint.
3Ease of manufacture
If the conductive terminal has an excessive strip connecting portion, then the terminal can be connected to the strip for carrying, but the space required increases and miniaturization is limited
Solution Approach 1:
The patent removes the excessive strip connecting portion from the conductive terminal, keeping only the essential terminal structure. The connection to the strip is maintained through a simplified interface, eliminating the volume-consuming connecting portion while preserving the functional connection capability.
Solution Approach 2:
Instead of having the terminal include the strip connecting portion (traditional approach), the patent inverts the relationship by having the strip connect to a minimized terminal structure. This reversal allows the terminal to be much smaller while maintaining the connection function through the strip's structure.

AI summary
An electrical connector includes a body having an accommodating hole running vertically therethrough, and a conductive terminal accommodated in the accommodating hole. The conductive terminal includes: an upper terminal, having an upper base and an upper elastic arm formed by extending from the upper base; an upper connecting member, fixed on the upper base in a front-rear direction to be connected to a first strip; a lower terminal, electrically connected with the upper terminal and having a lower base and a lower elastic arm extending from the lower base; and a lower connecting member, fixed on the lower base in the front-rear direction to be connected to a second strip. The upper terminal, the lower terminal, the upper connecting member and the lower connecting member are formed separately. The upper extending portion and the lower extending portion are provided side by side and jointly positioned in the accommodating hole.
