Board-to-Board Connector Reinforcing Brackets for Guide Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional board-to-board connectors are prone to damage or breakage during fitting due to the difficulty in aligning the fitting faces, especially with the miniaturization and height reduction of connectors, leading to potential damage of the thin guide portions.
Innovation Solution
The integration of reinforcing brackets in the fitting guide portions of the first housing of the board-to-board connector, which include concave portions and end wall portions with reinforcing brackets that cover and protect the fitting side faces, preventing damage during the fitting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the guide portions are made thin to reduce connector size, then miniaturization is achieved, but the guide portions become easily broken during fitting
Solution Approach 1:
The guide portion is divided into two functional segments: the original thin guide portion for alignment and a separately attached reinforcing bracket for strength. This segmentation allows each part to optimize its function without compromising the other.
Solution Approach 2:
The reinforcing bracket is integrated with the guide portion through attachment, combining the alignment function of the thin guide portion with the structural strength of the bracket into a unified assembly that provides both miniaturization and durability.
2Length of moving object
If the operator performs fitting by groping due to miniaturization, then connector height is reduced, but misalignment causes damage to the fitting faces
Solution Approach 1:
The reinforcing bracket is pre-positioned on the guide portion before fitting, establishing a robust structural foundation that prevents damage during the subsequent groping alignment operation, enabling safe miniaturized fitting.
3Volume of moving object
If the guide portions are made thin for miniaturization, then connector size is reduced, but the fitting faces become susceptible to breaking under thrust
Solution Approach 1:
The guide portion is segmented into the thin alignment feature and the separately attached reinforcing bracket, allowing the main body to remain compact while the bracket provides dedicated structural support to prevent fitting face breakage.
Solution Approach 2:
The reinforcing bracket acts as an intermediary structural element between the thin guide portion and the fitting face, absorbing and distributing thrust forces to protect the vulnerable fitting face from breaking during misalignment.

AI summary
A board-to-board connector is disclosed. The board-to-board connector comprises a first connector and a second connector. The first connector has first terminals and a first housing which has first fitting guide portions formed at both ends in the longitudinal direction of the first housing. The second connector has second terminals configured to make contact with the first terminals, and a second housing which has second fitting guide portions formed at both ends in the longitudinal direction of the second housing and configured to engage with the first fitting guide portions.
