Spring Connector Waterproof Elastic Member Deformation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spring connectors face challenges in maintaining waterproof properties due to deformation of the elastic member spreading to the periphery, making it difficult to accurately determine the position of pins and distance between adjacent pins.
Innovation Solution
A spring connector design featuring a first pin, an intermediate member electrically connected to the first pin, a spring for applying contact force, and a waterproof elastic member interposed between the first pin and the intermediate member, with a cylindrical part of the elastic member positioned between the inner surface of a hole and the outer surface of a rod-shaped part, and a convex part pressing the elastic member to prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the through-hole provided in the elastic member is expanded with a single part to secure waterproof properties, then waterproofing is achieved, but deformation of the elastic member spreads to the periphery making it difficult to accurately determine pin positions and distances between adjacent pins
Solution Approach 1:
The invention divides the elastic member into multiple independent elastic fingers (first elastic finger, second elastic finger, etc.), each having its own through-hole and contact pin. This segmentation prevents deformation from spreading across the entire elastic member, as each finger deforms independently during insertion. The waterproof seal is maintained at each individual through-hole location without affecting adjacent fingers, thus preserving pin position accuracy while achieving waterproofing.
Solution Approach 2:
The waterproof elastic member is designed with localized sealing features at each through-hole position rather than a single expanded through-hole affecting the entire structure. Each elastic finger provides localized waterproofing at its specific contact pin location, allowing precise positioning of multiple pins without mutual interference or deformation spread.
2Reliability
If the through-hole is expanded to secure waterproof properties, then waterproofing is achieved, but it becomes difficult to accurately determine the distance between adjacent pins
Solution Approach 1:
By segmenting the elastic member into multiple independent fingers, each with its own through-hole and pin, the invention enables precise measurement and positioning of each pin independently. The distance between adjacent pins can be accurately determined during manufacturing since each finger operates independently, unlike a single expanded through-hole structure where deformation makes measurement difficult.
3Reliability
If a single part expands the through-hole for waterproofing, then waterproofing is secured, but the deformation spreads making it difficult to determine contact part position
Solution Approach 1:
The elastic member is divided into multiple independent elastic fingers, each with its own contact pin and through-hole. This segmentation isolates the deformation to each individual finger during insertion, allowing the contact part position to be accurately determined for each pin without interference from adjacent areas. The waterproof seal is maintained locally at each through-hole position.
4Reliability
If the elastic member is deformed to secure waterproofing, then waterproofing is achieved, but the deformation spreads to the periphery
Solution Approach 1:
The elastic member is divided into multiple independent elastic fingers that are structurally separated. When deformation occurs during insertion, it is confined to each individual finger rather than spreading to the periphery of the entire elastic member. This segmentation maintains the overall structural stability and composition of the elastic member while achieving waterproofing at each contact point.
Solution Approach 2:
The waterproofing function is localized to specific regions at each through-hole position rather than requiring global deformation of the entire elastic member. Each elastic finger provides localized sealing, preventing deformation spread while maintaining waterproof properties where needed.

AI summary
Provided is a spring connector capable of preventing deformation of a waterproof elastic member from being spread to a periphery. A spring connector includes a first pin having a contact part with an object, a spring for applying a contact force with the object to the first pin, an intermediate member held by the first pin so as to move together with the first pin by pressing-in or the like, and a waterproof elastic member which is interposed between the first pin and the intermediate member and watertightly seals a space between the first pin and the intermediate member.
