Keystone Jack Partition Walls Hooked Portions Cover Shells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial keystone jacks do not allow for a selective connection arrangement between the wire-bonding block panel of the IDC housing and the core wires of the network cable using either a punch down technique or a tool-free technique.
Innovation Solution
A keystone jack design featuring a jack body with gold-plated pins, an IDC housing with partition plates and hooked portions, a wire layout cover for suspended core wire placement, and pivotally coupled cover shells for tool-free or punch down installation, enabling secure connection of core wires to the wire-bonding block panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a punch down type keystone jack is used, then the core wires can be securely connected to the wire-bonding block panel, but a tool is required for installation
Solution Approach 1:
The cover shells are designed to be pivotally coupled to the jack body, allowing them to move between an open position for wire insertion and a closed position for securing connections. This dynamic mechanism enables the transition from tool-free wire placement to tool-assisted connection securing, resolving the contradiction between ease of operation and connection reliability
2Ease of operation
If a tool free type keystone jack is used, then the installation is simpler and no tool is needed, but the connection securing mechanism is less reliable
Solution Approach 1:
The pivotally coupled cover shells provide a dynamic closing action that transitions the connection from a loose suspended state to a securely held state. When closed, the cover shells mechanically secure the core wires to the wire-bonding block panel, providing reliable connections without requiring external tools during installation
3Device complexity
If a single connection method is used in keystone jacks, then the device structure is simpler, but the adaptability to different installation preferences is reduced
Solution Approach 1:
The keystone jack integrates both punch down type and tool free type connection capabilities into a single device. The wire-bonding block panel with hooked portions can accommodate both suspended wire placement (tool-free) and punch down connections (tool-assisted), making the device universal and adaptable to different installation preferences and requirements

AI summary
A keystone jack based on a punch down type keystone jack architecture, having a wire layout cover attached to the rear side of the jack body and two cover shells pivotally connected to the jack body for closing/opening the wire layout cover. The IDC housing at the back side of the jack body has a wire-bonding block panel formed of multiple partition plates and a retaining hook located on the distal end of each partition plate to minimize the gap between each two adjacent partition plates, allowing installation of the core wires of the inserted network cable by a punch down type technique or a tool free type technique.
