Dual-Movable Connector Layout for Stable Terminal Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face issues with relative position deviation between terminals held by movable housings, potential breakage of restraint space forming portions, and difficulty in downsizing due to the arrangement of multiple connectors on a substrate.
Innovation Solution
The connector design integrates the terminal holding portions of the fixing housing with resin, incorporates a restraining mechanism with reinforcing walls, and optimizes the arrangement of movable housings to prevent positional deviation and breakage while allowing for downsizing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple connectors are arranged close to each other on a substrate to transmit many signals, then the signal transmission capability is improved, but the relative positions of terminals held by movable housings may deviate from predetermined positions
Solution Approach 1:
The patent merges multiple terminal holding portions into a single integrally molded fixing housing. The fixing housing includes first and second terminal holding portions that are formed as one piece through integral molding, which ensures that the relative positions of terminals held by different movable housings maintain predetermined positions without deviation, even when multiple connectors are arranged closely on a substrate.
2Reliability
If a restraint space forming portion with pair of side walls and top wall is formed in fixing housing, then the movable housing is restrained, but the restraint space forming portion may breakage
Solution Approach 1:
The patent applies local quality by making the fixing housing integrally molded with resin, which provides uniform structural strength throughout the entire housing including the restraint space forming portion. The integral molding ensures that the pair of side walls and top wall forming the restraint space have sufficient strength to prevent breakage while maintaining the restraint function against the movable housing.
3Adaptability or versatility
If multiple movable housings are provided in the connector, then the connector functionality is improved, but the connector size increases in the arrangement direction
Solution Approach 1:
The patent arranges multiple movable housings in the width direction rather than extending them in the arrangement direction. This dimensional reorganization allows the connector to accommodate multiple movable housings (first and second movable housings) while controlling the overall size in the arrangement direction, effectively transitioning from a linear expansion to a planar layout.

AI summary
When a first movable housing and a second movable housing are provided, relative positions of a first terminal and a second terminal are prevented from deviating from predetermined positions. A connector 1 includes a fixing housing 2, a first movable housing 31, a second movable housing 32, a first terminal 41, and a second terminal 42. The fixing housing 2 includes the first terminal holding portions 21A that hold the first fixing-side held portions 4B of the first terminals 41, and the second terminal holding portions 22A that hold the second fixing-side held portions 4B of the second terminals 42. The first terminal holding portion 21A and the second terminal holding portion 22A of the fixing housing 2 are integrally molded with resin.
