Keystone Jack Cover Structure for Balanced Thick-Wire Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing keystone jack assemblies face challenges in maintaining a short, slim, and compact size while avoiding unbalanced installation, especially with thicker wires that require enhanced communication capabilities, leading to difficulties in proper mounting due to increased wire cap heights and deflection issues during installation.
Innovation Solution
A keystone jack assembly design featuring a wire cap with guiding portions and a cover that pivotally connect to the jack housing, ensuring progressive contact and stable mounting through strategically angled surfaces and guiding surfaces, preventing unbalanced pressing and deflection, and allowing for secure engagement without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If thicker wires are employed to enhance communication ability, then communication capability is improved, but wire cap height increases making installation difficult
Solution Approach 1:
The cover is divided into two separate covering parts that can pivot independently, allowing each part to apply pressure to opposite sides of the wire cap separately. This segmentation enables progressive contact and prevents unbalanced pressing that would occur with a single-piece cover, making installation of taller wire caps feasible.
Solution Approach 2:
The covering parts are designed to pivot dynamically during installation rather than being fixed. This dynamic motion allows the covering parts to progressively contact the wire cap and apply balanced pressure throughout the installation process, accommodating the increased height from thicker wires.
2Adaptability or versatility
If wire cap height increases due to thicker wires, then communication capability is improved, but mounting balance deteriorates causing deflection
Solution Approach 1:
By dividing the cover into two symmetric covering parts that pivot independently, the system ensures balanced pressure distribution on the wire cap. Each covering part applies force to opposite sides simultaneously, preventing deflection and maintaining mounting stability despite the increased wire cap height.
Solution Approach 2:
The guiding portions are designed with asymmetric angled surfaces that guide the covering parts during pivoting. This asymmetric geometry ensures that the covering parts maintain proper alignment and apply balanced pressure throughout the installation motion, preventing unbalanced mounting.

AI summary
A keystone jack assembly includes a jack housing, a piercing contact housing disposed on the jack housing, a plurality of piercing contacts mounted on the piercing contact housing, a wire cap movably disposed on the piercing contact housing and a cover pivotally connected to the jack housing. The wire cap includes a cap main body, at least one first guiding portion, at least one second guiding portion and a third guiding portion. The cover includes two covering parts, and each covering part includes a main body, at least one first contact portion, at least one second contact portion and a third contact portion. The first contact portion abuts against the first guiding portion, the second contact portion abuts against the second guiding portion and the third contact portion abuts against the third guiding portion in order as the two covering parts pivots toward each other.
