Connector Bottom-Wall Protrusion for Reflow Carrier Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors mounted on connecting members tend to tilt and fail to secure terminals properly due to wobbling on reflow carriers, requiring special carriers that are time-consuming to produce.
Innovation Solution
A connector design with a housing and terminals arranged along specific axes, featuring a center of gravity plane and protrusion parts to stabilize the connector on existing reflow carriers, reducing height and preventing inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the connector is designed to prevent the connecting member from being inserted into the opponent housing to reduce height, then the height is reduced, but the connector becomes biased to one side with respect to the center of gravity, causing inclination when placed on an existing reflow carrier
Solution Approach 1:
The invention applies asymmetry by providing a protrusion part on the non-facing region of the bottom wall that is positioned asymmetrically with respect to the center of gravity plane. This asymmetric protrusion creates a counterbalancing effect that adjusts the center of gravity position, allowing the connector to maintain stability and prevent inclination when placed on an existing reflow carrier, even though the overall structure is asymmetric due to the height reduction design
2Stability of the object's composition
If a special reflow carrier is created to prevent the connector from wobbling, then the connector stability is improved, but the manufacturing time and effort increase
Solution Approach 1:
The invention applies self-service by designing the connector itself to have the stability function through the protrusion part on its bottom wall. Instead of requiring the reflow carrier to provide stabilization features, the connector's own structure (with the protrusion part) enables it to prevent wobbling and maintain stability when placed on an existing standard reflow carrier, making the connector self-stabilizing
Solution Approach 2:
The invention applies universality by designing the connector to work with existing standard reflow carriers without requiring specialized or modified carriers. The protrusion part on the bottom wall enables the connector to be universally compatible with conventional reflow carriers while maintaining stability, eliminating the need for dedicated special-purpose carriers

AI summary
A connector has a housing having a bottom wall; and a plurality of terminals. A lower side surface of the bottom wall in the top-bottom axis has a first region and a second region divided into two by a center of gravity plane including a center of gravity. The first region has a facing region that faces the connecting member when the connecting parts of the plurality of terminals is mounted on the connecting member, and the second region is a non-facing region that does not face the connecting member. The second region has a back surface positioned at the upper side in the top-bottom axis with respect to an imaginary plane including the mounting surface of the connecting part; and a protrusion part protruding downward from the back surface in the top-bottom axis.
