Keystone Jack Double Hook Trough Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keystone jacks have insufficient engagement strength due to a single engaging means, leading to stress concentration and potential damage when handling Network cables.
Innovation Solution
The keystone jack incorporates double engaging means, with first and second hooks and troughs on both sides of the main body, printed circuit board, and terminal base, respectively, to enhance the connection strength and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single engaging means is used to connect components, then the device complexity is reduced, but the engagement strength is insufficient and stress concentration occurs
Solution Approach 1:
The engaging mechanism is segmented into multiple independent engaging means (first engaging means with first hooks and first troughs, second engaging means with second hooks and second troughs) distributed at different locations. This segmentation allows the engagement strength to be distributed across multiple points, preventing stress concentration while maintaining reasonable device complexity through modular engagement structures.
Solution Approach 2:
Multiple engaging means are merged into a unified connection system where first and second hooks engage with corresponding troughs simultaneously. This merging of multiple engagement points creates a combined effect that significantly increases overall engagement strength and distributes stress across the entire engagement system rather than concentrating it at a single point.
2Reliability
If multiple engaging means are provided on both sides, then the engagement strength is increased and stress concentration is avoided, but the manufacturing complexity increases
Solution Approach 1:
The engaging structures are segmented into standardized first hooks, first troughs, second hooks, and second troughs that can be manufactured independently and assembled systematically. This segmentation enables modular manufacturing processes, reducing overall manufacturing complexity while achieving high reliability through multiple engagement points distributed on both sides of the components.
Solution Approach 2:
Different engaging means are positioned at specific locations (first engaging means at one location, second engaging means at another location) to optimize stress distribution. This local quality approach ensures that each engaging means is placed where it can most effectively contribute to durability, with the parallel arrangement on both sides providing balanced support and preventing stress concentration at any single point.
3Strength
If engaging means are provided in parallel to the inserting direction, then the strength for sustaining insertion and removal is increased, but the device structure becomes more complex
Solution Approach 1:
The engaging means are segmented and arranged in parallel to the inserting direction, with first hooks and first troughs forming one parallel set and second hooks and second troughs forming another parallel set. This parallel segmentation provides multiple load-bearing paths that sustain insertion and removal forces effectively, while the modular nature of each segment keeps the overall structural complexity manageable through systematic arrangement.

AI summary
A keystone jack includes a main body, a printed circuit board, a terminal base, and a plurality of terminals. Both sides of the main body have two first troughs and two second troughs. The printed circuit board is inserted into the main body and has two first hooks engaged with the two first troughs on its both sides. The terminal base is disposed on the printed circuit board and assembled with the main body. Both sides of the terminal base are formed with two second hooks engaged with the two second troughs. Both ends of each terminal are fixedly inserted into the printed circuit board and the terminal base respectively. By these two engaging means, the engagement strength of the components of the keystone jack is increased to thereby prevent the keystone jack from suffering damage.
