Lever Connector Seal Compression Without Engagement Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face challenges in improving operability due to engagement resistance between the lever member and the rear holder, which hinders further enhancements in connecting a housing and a mating connector.
Innovation Solution
The connector design includes a housing with a first member for supporting the lever member and a second member that accommodates the sealing member, featuring a pressed portion and a pressing portion. The pressed portion is initially non-engaged with the lever member until it contacts the pressing portion during the displacement process, thereby avoiding engagement resistance and improving operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pressed portion is engaged with the lever member throughout the entire displacement process, then the sealing member can be compressed effectively, but engagement resistance increases and operability deteriorates
Solution Approach 1:
The pressed portion is designed to be non-engaged with the lever member during the initial phase of the displacement process. The engagement only occurs when the pressing portion contacts the pressed portion, which happens after the lever member has already been displaced to a certain position. This preliminary non-engagement phase allows the lever member to move freely without engagement resistance, improving operability while still achieving the sealing compression function when needed.
2Reliability
If the pressed portion is engaged with the lever member throughout the entire displacement process, then the sealing member is compressed, but the connection resistance increases

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances operability by eliminating engagement resistance between the pressed portion and the lever member, allowing for smoother connection of the housing and the mating connector, while ensuring the sealing member is compressed for a liquid-tight seal.

AI summary
A housing (11) includes a first member (16) for supporting a slider (14) serving as a lever member and a second member (17) for accommodating a sealing member (15) in an accommodation space (25) formed between the first member (16) and the second member (17) to sandwich the sealing member (15) in a front-rear direction. The second member (17) includes a pressed portion (29). The lever member includes a pressing portion (65) for pressing the second member (17) in a direction to reduce a dimension in the front-rear direction of the accommodation space (25) by contacting the pressed portion (29). The pressed portion (29) is arranged in a non-engaged state with the lever member until contacting the pressing portion (65) in a displacement process.
