Movable Housing Connector Release Timing for Lower Connection Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors require high dimensional accuracy to synchronize the locking and unlocking of terminal holders, leading to potential misalignment and increased connection resistance, which can hinder the connecting operation if timings are off.
Innovation Solution
A connector design featuring a first housing with a movable housing that has initial and connection position holding portions, where the facing interval is adjusted to minimize initial connection resistance and release holding at a precise moment to prevent peak resistance, allowing for smooth connection without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the locking of fixed terminal holder and movable terminal holder is maintained during connection, then the pushing force is transmitted properly, but the connection resistance peaks when movable terminal holder completes connection
Solution Approach 1:
The holding releasing portion is designed to release the locking of the fixed terminal holder before the movable terminal holder completes its connection. This preliminary action prevents the pushing force from being transmitted to the movable terminal holder at the critical moment when connection resistance would peak, thereby solving the contradiction between force transmission and resistance reduction.
2Object-generated harmful factors
If the holding releasing portion synchronizes with movable terminal holder connection completion, then peak connection resistance is reduced, but very high dimensional accuracy is required
Solution Approach 1:
The holding releasing portion acts as an intermediary mechanism that indirectly controls the timing of fixed terminal holder release. Instead of directly synchronizing with movable terminal holder position, it uses the engagement and disengagement of protrusions and recesses during the connection process to automatically release the locking at the appropriate moment, eliminating the need for high dimensional accuracy.
3Reliability
If the holding releasing portion releases too early or too late, then the locking is not properly released, but the connecting operation is hindered
Solution Approach 1:
The holding releasing portion is designed to automatically release the locking of the fixed terminal holder through its own engagement and disengagement mechanism during the connection process. The protrusion and recess geometry ensures that release occurs at the correct moment without external control, making the system self-regulating and preventing operational hindrances.

AI summary
It is aimed to enable a peak value reduction of connection resistance without hindering a connecting operation. A first housing includes an initial position holding portion for holding a movable housing at an initial position and a connection position holding portion for holding the movable housing at a connection position. A facing interval between the movable housing at the initial position and the second housing is narrower than that between a housing body and the second housing, and a facing interval between the movable housing at the connection position and the second housing is equal to that between the housing body and the second housing. The second housing is provided with a holding releasing portion for releasing holding by the initial position holding portion when the movable housing reaches a position just before a proper connection position in a connection process to the first housing.
