Female Connector Front Retainer Stroke Without Looseness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing female connectors with front retainers face challenges in extending the stroke between the allowed and regulated positions without causing looseness, which complicates the retention mechanism.
Innovation Solution
The female connector design includes a female housing with an insertion guide portion and a front retainer that is movable between allowed and regulated positions, where the insertion guide portions contact the circumferential wall to stabilize the front retainer, preventing looseness and allowing for a larger stroke.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the stroke between the allowed position and regulated position of the front retainer is extended, then the retention flexibility is improved, but looseness occurs in the front retainer at the allowed position
Solution Approach 1:
The insertion guide portion acts as an intermediary element between the front retainer and the main body portion. It provides a guided interface that allows the front retainer to move along a defined path while maintaining proper positioning and preventing looseness during the extended stroke motion.
Solution Approach 2:
The front retainer is designed to be movable between allowed and regulated positions through the insertion guide portion. This dynamic configuration enables the stroke extension while the insertion guide ensures stability is maintained throughout the motion range, preventing looseness at the allowed position.
2Adaptability or versatility
If the front retainer is made movable to regulate lance bending, then the control capability is improved, but the structural complexity increases
Solution Approach 1:
The insertion guide portion is integrated into the main body portion of the female housing, merging the guiding function with the structural body. This reduces overall structural complexity while still enabling the front retainer's movable control capability for regulating lance bending.
Solution Approach 2:
The front retainer serves multiple functions: it acts as a regulatory element for lance bending control, provides structural support, and guides insertion through its interaction with the insertion guide portion. This multi-functionality reduces the need for separate components, thereby reducing structural complexity.

AI summary
A female connector is provided with a female housing and a front retainer. The female housing includes a main body portion and insertion guide portions extending forward from a front-end surface of the main body portion. The main body portion includes a female terminal accommodation cavity accommodating the female terminal and a lance engaging with the female terminal. The front retainer is attached to the main body portion to be movable in a front-rear direction across a range between an allowed position where bending of the lance is allowed and a regulated position where the bending of the lance is regulated. In a state where the front retainer is positioned at the allowed position, the insertion guide portions are in contact with an inner surface of a circumferential wall of the front retainer.
