Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connection terminals face issues with contact member floating relative to the inner circumferential face of the female connector, leading to reduced durability and insertion workability due to deformation and collision with the male connector.
Innovation Solution
A connection terminal design featuring a contact member with an arcuate shape and a floating inhibiting part that generates a resilient force to prevent floating, using first and second contacts and receiving parts to apply pressing forces, ensuring stable electrical connection and improved durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the contact member is formed in a tubular shape with elasticity to establish electric connection, then electrical connection between the female connector and male connector is established, but the contact member may float relative to the inner circumferential face of the female connector
Solution Approach 1:
The contact member is divided into multiple independent contacts (first contact and second contact) rather than a single tubular structure. This segmentation allows each contact to be independently positioned and stabilized, preventing floating while maintaining electrical connection functionality.
Solution Approach 2:
A pressing force applying part is introduced as an intermediary component between the contact member and the female connector. This intermediary applies a pressing force to the first contact, stabilizing its position relative to the inner circumferential face and preventing floating.
2Volume of moving object
If the contact member is inserted into the internal space with its diameter made narrower, then the contact member can be accommodated into the internal space, but the contact member is deformed to a plastic region to reduce spring force against the inner circumferential face
Solution Approach 1:
The contact member is segmented into multiple contacts, allowing each to be independently sized and positioned. This enables the contacts to maintain adequate spring force while fitting within the internal space, avoiding the need for excessive diameter reduction that would cause plastic deformation.
Solution Approach 2:
The design changes the structural parameters of the contact member from a single tubular form to multiple discrete contacts with specific spacing and dimensions. This parameter optimization allows the contacts to maintain elastic deformation within the linear region, preserving spring force while accommodating the internal space constraints.
3Adaptability or versatility
If the contact member floats relative to the inner circumferential face of the female connector, then the male connector may collide with the contact member, but this causes reduction in durability and insertion workability
Solution Approach 1:
The pressing force applying part acts as an intermediary that stabilizes the first contact's position. By applying a controlled pressing force, it prevents the contact from floating and colliding with the male connector during insertion, thereby improving durability and insertion workability while maintaining necessary flexibility for electrical connection.

Function Achieved in This Case
The solution effectively inhibits contact member floating, enhancing durability and insertion workability by maintaining stable electrical connections and reducing positional deviations, thereby improving the overall performance and productivity of the connection terminal.
Implementation Method 1
a floating inhibiting part that is formed in an arcuate shape in the circumferential direction of the inner circumferential face of the female connector, and that applies a pressing force corresponding to a resilient force generated according to a change in a curvature of the arcuate shape to the female connector

AI summary
A connection terminal includes a terminal main body having a female connector with an internal space into which a male connector is inserted and a contact member accommodated into the internal space of the female connector. The contact member has a first contact electrically connected to the female connector, a second contact coupled to the first contact and pushed outward in a radial direction by the male connector in the internal space to be electrically connected to the male connector, and a floating inhibiting part that applies a pressing force to the female connector, generates a force in a pressing direction toward an inner circumferential face of the female connector by a reaction force from the female connector against the pressing force, and inhibits the floating of the first contact relative to the inner circumferential face of the female connector by the force in the pressing direction.
