Connector Terminal Space Prevents Solder Infiltration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors face issues with preventing the obstruction of connective connections between the terminal and object components due to the flow of solder or flux into the joint spring part, which hinders elastic deformation and conductive connections.
Innovation Solution
The connector design incorporates a space surrounding the terminal, formed by recesses in the housing and contact, that prevents the flow of solder or flux into the displaceable portion of the joint spring part, ensuring unobstructed elastic deformation and conductive connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal is accommodated in the housing with the joint spring part exposed, then the elastic deformation function is maintained, but solder or flux flows into the joint spring part through capillary action and obstructs the connective connection
Solution Approach 1:
The housing is segmented to form a dedicated space that separates the joint spring part from the soldering area. This spatial segmentation prevents solder or flux from reaching the joint spring part while maintaining the elastic deformation function of the joint spring part.
Solution Approach 2:
The space formed by the housing acts as an intermediary barrier between the soldering area and the joint spring part. This intermediate space blocks the capillary action of solder or flux, preventing harmful substance infiltration while allowing the joint spring part to function normally.
2Reliability
If the joint spring part is made highly elastic for better connection, then the connective connection quality improves, but the risk of solder or flux infiltration increases due to more pronounced capillary action
Solution Approach 1:
The joint spring part is extracted from the direct soldering path by forming a separate space around it. This extraction removes the source of capillary action (the joint spring part) from the harmful environment (soldering area), allowing high elasticity to be maintained without increased infiltration risk.
Solution Approach 2:
The space formed by the housing, which initially might seem to add complexity, actually converts the potential harm of exposed joint spring parts into a benefit by creating a protective barrier. This space utilizes the housing structure itself to prevent solder or flux infiltration while preserving the elastic deformation capability.
3Device complexity
If the terminal structure is simplified without the protective space, then the device complexity is reduced, but solder or flux can flow into the joint spring part and obstruct elastic deformation
Solution Approach 1:
The protective space is merged with the existing housing structure rather than being a separate component. This integration combines the housing's structural function with the protective barrier function, preventing solder or flux infiltration without adding separate protective components that would increase device complexity.
Solution Approach 2:
The housing serves multiple functions: it accommodates the terminal, provides structural support, and forms the protective space that prevents solder or flux infiltration. This multi-functionality eliminates the need for separate protective structures, maintaining simplicity while ensuring reliability of the elastic deformation function.

AI summary
A connector includes a housing configured to have an object component be inserted therein, and a terminal accommodated in the housing and configured to be conductively connected to the object component. The terminal includes a first base part, a second base part disposed apart from the first base part, and a joint part joining the first base part to the second base part. The joint part elastically deforms so as to move the second base part relative to the first base part. The first base part includes a base body and a mount portion connected to the base body at a first connection point. The mount portion is mountable onto an object device with a mount agent. The joint part includes a root portion joined to the base body and a displaceable portion connected to the root portion at a second connection point. The displaceable portion is displaceable relative to the root portion. A space preventing the mount agent from moving to the displaceable portion is formed around the terminal between the second connection point and the first connection point. This connector prevents connective connection with the object component from being obstructed.
