Front-Access Latching for Damage-Free Connector Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high speed modular twisted-pair-data connectors face challenges in easy, secure, and safe disassembly due to the need for accessing locking mechanisms from lateral sides, which can lead to damage or breakage.
Innovation Solution
A connector assembly design with an elongated inner signal contact and insulating element featuring a first cavity for the contact and a second cavity for a tool, allowing insertion from opposite sides, and a latching element with a protrusion and hook section for secure disengagement using a pivot mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a locking mechanism with a cavity for tool access is provided on the side of the insulating element, then the inner signal contact can be secured and released, but the cavity becomes inaccessible when multiple contacts are mounted side-by-side or when the device is mounted with only front-side access available
Solution Approach 1:
The locking mechanism is repositioned from a lateral cavity access (horizontal dimension) to a front-side cavity access (vertical dimension relative to the contact insertion direction). This dimensional change allows the tool access cavity to be positioned at the front of the insulating element, making it accessible in all mounting configurations without requiring lateral access to the device.
2Ease of repair
If a standard tool such as a slotted screwdriver is used to operate the locking mechanism, then the mechanism can be unlocked, but unguided movement risks damaging or breaking the locking mechanism
Solution Approach 1:
A dedicated unlocking tool serves as an intermediary between the user and the locking mechanism. This specialized tool features a guide portion that fits into the tool access cavity and provides guided movement, ensuring the locking mechanism is operated correctly without unguided movements that could cause damage. The tool mediates the interaction to prevent damage while maintaining serviceability.
3Ease of operation
If the locking mechanism is accessed via a lateral cavity, then the inner signal contact can be released, but the cavity may be impossible to access when the device is mounted with limited accessibility
Solution Approach 1:
The tool access cavity is designed to be positioned at the front of the insulating element, making it universally accessible from the front side regardless of how the device is mounted. This universal positioning allows the locking mechanism to be serviced in all mounting configurations (front-side access, side access, rear access) without requiring different tool access points, thereby achieving multi-configurational compatibility.

AI summary
A connector assembly comprises an elongated inner signal contact and an insulating element, wherein the insulating element includes a first cavity configured to accommodate the inner signal contact, a latching element configured to secure the inner signal contact in the first cavity, and a second cavity extending in an axial direction and configured to receive a tool for separating the latching element from the inner signal contact.
