Connector Reinforcement Member Embedding via Insert-Molding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face challenges in embedding reinforcement members via insert-molding, particularly when the connector's profile is low, as previous designs are not suitable for insert-molding or may not be securely embedded.
Innovation Solution
A connector design featuring a reinforcement member with a reversed U- or V-shape rib portion that is embedded in the housing's bottom portion via insert-molding, ensuring a large contact area and smooth resin movement, even at shallow depths, using a housing made of insulating material like resin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the connector profile is reduced to a low height, then the connector becomes more compact and space-efficient, but the reinforcement member cannot be securely embedded via insert-molding
Solution Approach 1:
The reinforcement member features a rib portion with a reversed U- or V-shape cross-section that is specifically designed to be filled with resin. This localized structural feature creates a reliable embedding mechanism in the bottom portion of the housing without requiring the entire connector to have increased height, thus resolving the contradiction between low profile and secure embedding.
Solution Approach 2:
The rib portion of the reinforcement member is pre-formed with a shape that facilitates resin filling during insert-molding. The reversed U- or V-shape cross-section is designed in advance to guide resin flow and ensure complete filling, enabling secure embedding even when the overall connector height is minimized.
2Length of stationary object
If the reinforcement member is embedded at shallow depth to maintain low profile, then the connector remains compact, but the contact area between housing and reinforcement member is insufficient
Solution Approach 1:
The rib portion is designed with a reversed U- or V-shape cross-section that extends in the longitudinal direction of the connector. This dimensional configuration increases the contact area between the reinforcement member and housing bottom portion without increasing the embedding depth, allowing shallow embedding while maintaining large contact area for secure attachment.
3Device complexity
If a traditional reinforcement member design is used, then the structure is simple, but the member is not suitable for insert-molding and cannot be securely embedded
Solution Approach 1:
The reinforcement member's cross-sectional shape is changed to a reversed U- or V-shape for the rib portion. This parameter change in geometry makes the reinforcement member suitable for insert-molding by enabling resin filling, while maintaining relative structural simplicity and not significantly increasing manufacturing complexity.
