Connecting Component Guide Structure Prevents Stub Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting components for mounting subsidiary boards suffer from deteriorated high-frequency characteristics due to the formation of stubs when using up-turned connector terminals, which impede signal transmission at high speeds, and alternative terminal shapes risk damaging the components or the boards during insertion.
Innovation Solution
A connecting component with a housing, housing connection terminals, and guide portions forming an insertion path that prevents contact between the subsidiary board and the terminals, allowing the board to pivot and establish contact with the terminals from beneath, thus avoiding stub formation and enabling smooth attachment with gull-wing shaped terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector connection terminals are formed with an up-turned shape to enable smooth insertion of the card, then the ease of operation is improved, but the high frequency characteristics are deteriorated due to stub formation
Solution Approach 1:
Instead of having the terminal tips turned up away from the card (conventional design), the patent inverts the approach by having the card pivot to contact the terminal tips from beneath. The terminal tips extend in the card insertion direction without being turned up, and the card's connection terminals make contact with the connector's connection terminals by pivoting upward after insertion, eliminating stub formation while maintaining smooth insertion
Solution Approach 2:
The patent introduces a dynamic pivoting motion of the card after insertion. The card is inserted horizontally along the groove, then pivots upward around a pivot point to bring the connection terminals into contact with the connector terminals. This dynamic transition from horizontal to angled contact eliminates the need for static up-turned terminal tips
2Reliability
If the tips of the connector connection terminals are formed into a straight line to avoid stub formation, then the high frequency characteristics are improved, but the connector connection terminals may hit the forward end of the card or abrade the card surface during insertion
Solution Approach 1:
The patent performs the contact action preliminarily by designing the card and connector terminals to contact each other before the card reaches its final position. The card pivots upward after insertion to make contact with the terminals, ensuring that the straight terminal tips do not hit or abrade the card during the insertion process itself
Solution Approach 2:
The patent introduces a groove structure as an intermediary element that guides the card during insertion. The groove constrains the card's movement path, ensuring smooth insertion and proper positioning before the pivoting contact occurs, thereby preventing direct impact or abrasion between the straight terminal tips and the card

AI summary
A connecting component includes a housing, housing connection terminals secured to the housing, an abutment located beneath the housing connection terminals, a first guide portion located beneath the housing connection terminals for regulating a position of a bottom surface of the subsidiary board, second guide portions located in front of the first guide portion as seen in a subsidiary board insertion direction for regulating the top surface of the subsidiary board, and third guide portions located in front of the first guide portion as seen in the subsidiary board insertion direction on a straight line passing through the first guide portion and the second guide portions and disposed in a position away from the abutment by a distance longer than an overall length of the subsidiary board, the third guide portions regulating the position of the bottom surface of the subsidiary board.
