Electrical Connector Asymmetric Pressing Force Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors for chip modules often result in force unbalance during assembly, leading to potential deformation of conductive terminals and poor electrical contact due to asymmetric distribution of downward force.
Innovation Solution
The electrical connector design includes a press cover with staggered pressing portions and a rocker mechanism, ensuring that the forces applied by the pressing portions are balanced, with the second pressing portion closer to the fixing portion than the first, eliminating force discrepancies and achieving stable contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the second rod is disposed on only one end of the first rod of the rocker, then the structure is simple, but the downward force applied on the chip module is unbalanced causing terminal deformation
Solution Approach 1:
The patent applies asymmetry by disposing the second rod at one end of the first rod rather than symmetrically. This asymmetric configuration, combined with the specific positioning of pressing portions at different distances from the pivot connection, creates a balanced force distribution system that resolves the contradiction between structural simplicity and force balance.
2Ease of operation
If the locking portion presses the tongue portion closer to the second rod, then the operating mechanism is simple, but the force distribution on the chip module becomes unbalanced
Solution Approach 1:
The patent applies local quality by positioning the pressing portions at different locations relative to the center line and pivot connection. The first pressing portion is positioned at a first distance while the second pressing portion is positioned at a second distance, creating locally differentiated force application points that achieve overall force balance and reliable electrical connection.
3Manufacturing precision
If symmetric pressing portions are used, then the force balance is achieved, but the structure requires complex positioning to maintain symmetry
Solution Approach 1:
The patent deliberately uses asymmetric positioning of pressing portions relative to the pivot connection, with the first pressing portion at a first distance and the second pressing portion at a second distance. This asymmetric design, combined with the specific rocker geometry, achieves force balance without requiring complex symmetric positioning mechanisms.

AI summary
An electrical connector includes an electrical connecting base for bearing a chip module, a press cover and an operating member. The press cover is covering on the electrical connecting base, and has a first fixing portion and a second fixing portion. A center line of the press cover passes through the second fixing portion. The press cover is provided with a first pressing portion and a second pressing portion for pressing the chip module. The first pressing portion and the second pressing portion are respectively located on two sides of the center line, and the second pressing portion is closer to the second fixing portion than the first pressing portion is. The operating member has a locking portion for pressing the second fixing portion, and an operating portion extending from the locking portion. The first pressing portion is closer to the operating portion than the second pressing portion is.
