Stacking Connector Mechanical Engagement Eliminates Soldering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stacking connectors require cumbersome soldering operations for connecting socket and plug terminals, leading to potential damage and reduced mechanical bonding strength, especially when handling a large number of terminals.
Innovation Solution
The connector design eliminates the need for soldering by using a substrate insertion slot, a substrate attaching member with projections, and a plug substrate with concavities and notches, allowing for secure engagement of the plug substrate with the connector main body through sliding and engagement of projections and concavities, providing a high bonding strength without soldering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If socket terminals and plug terminals are bonded by solder to secure electrical and mechanical connection, then electrical connection reliability is improved, but manufacturing complexity and time increase significantly when the number of terminals is large
Solution Approach 1:
The patent extracts the soldering process entirely from the connection mechanism. Instead of bonding terminals through solder, the invention uses a mechanical pressing structure where the plug substrate is pressed into the connector main body, causing elastic deformation of pressing members to achieve both electrical contact and mechanical fixation without any soldering operation.
Solution Approach 2:
The patent replaces the thermal-chemical soldering system with a purely mechanical connection system. The elastic pressing members deform mechanically under pressing force to establish electrical contact and maintain mechanical bonding, substituting the traditional solder-based mechanical bonding with an elastic deformation-based mechanism.
2Strength
If solder is used to secure both electrical connection and mechanical bonding strength, then connection strength is improved, but the terminals become vulnerable to damage from detaching forces
Solution Approach 1:
The patent introduces elastic pressing members as intermediary elements between the plug substrate and connector main body. These pressing members absorb and distribute detaching forces through their elastic deformation, protecting the terminals from direct stress while maintaining connection strength. The pressing members act as a buffer that prevents force concentration on the terminals.
Solution Approach 2:
The elastic pressing members are pre-configured to provide cushioning protection against detaching forces. Their elastic properties allow them to deform and absorb impact forces before they can reach the terminals, providing beforehand protection against terminal damage from external forces.
3Reliability
If a large number of terminals are connected using conventional soldering methods, then electrical connection completeness is improved, but the soldering operation becomes cumbersome and time-consuming
Solution Approach 1:
The patent merges multiple functions into the single pressing action: electrical contact establishment, mechanical fixation, and alignment are all achieved simultaneously through one pressing operation. The plug substrate insertion automatically positions all terminals in contact with their corresponding pressing members, eliminating the need for separate soldering operations for each terminal.
Solution Approach 2:
The pressing members are pre-positioned and pre-configured within the connector main body before the plug substrate is inserted. This preliminary arrangement ensures that when the plug substrate is pressed in, all electrical connections are established automatically in the correct positions without requiring manual alignment or separate connection steps for each terminal.

AI summary
A stacking connector is formed by a connector main body and a plug substrate, the connector main body has a substrate sandwiching member including a sandwiching gap into which the plug substrate fits, and a projection projecting into the sandwiching gap, the plug substrate has a concavity with which the projection engages in both top and bottom surfaces, and, after inserting the plug substrate into the sandwiching gap of the substrate sandwiching member, by sliding the plug substrate in a direction at right angles to the insertion direction, the concavity engages with the projection and the plug substrate is linked to the connector main body in an unremovable state.
