Connector Device Guiding Hood Levers Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of SMT connectors used in electronic devices, particularly in vehicles, the positioning of multi-electrode connectors is challenging due to the lack of visibility in in-vehicle environments, leading to fumbling and reduced reliability of soldered connections, especially when external forces are applied during assembly.
Innovation Solution
A connector device featuring a guiding hood with locking means and levers that facilitate easy alignment and engagement of mating side connectors with board-mounted connectors, utilizing a flexible locking arm and beak parts to absorb external forces, thereby preventing damage to soldered parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a board mounted connector is used in an in-vehicle assembling environment, then the connector can be mounted on a board, but it cannot be seen clearly leading to positioning difficulty and fumbling
Solution Approach 1:
The guiding hood incorporates visual indicators such as color-coded alignment marks or contrasting colors on the positioning surfaces to enhance visibility. This allows operators to easily detect and align the board mounted connector with the mating side connector in the in-vehicle assembling environment, eliminating positioning difficulty caused by poor visibility
2Ease of operation
If external force is applied during assembly of the board mounted connector, then the connectors can be engaged, but the reliability of the soldered part decreases
Solution Approach 1:
The guiding hood acts as an intermediary mechanism between the operator's assembly action and the board mounted connector. It provides a guided pathway and positioning features that ensure proper alignment during engagement, distributing the applied force evenly and preventing excessive stress on the soldered joints, thus maintaining reliability while enabling easy engagement
3Force
If a lever-type connector is used to decrease inserting/removing force, then the operating force is reduced, but the external force from the lever is applied to the board mounted connector
Solution Approach 1:
The guiding hood extracts and isolates the force application path from the board mounted connector's soldered joints. By providing a separate guided engagement pathway, it allows the lever mechanism to apply operating force through the hood's structural framework rather than directly transmitting it to the vulnerable soldered parts, thus maintaining both low operating force and high reliability

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the ease of positioning and reduces the risk of soldered part failure by distributing external forces through the housing case, ensuring reliable connections and maintaining the integrity of the soldered parts during assembly.
Implementation Method 1
a flexible locking arm extending in a direction in which the mating side connectors are fitted with the board mounted connectors, the engaging part includes a beak part configured to engaged with the distal end of the locking arm
