Solution Overview

Problem

Existing cable connector assemblies face difficulties in making complementary connectors easy to insert and separate, requiring a flexible and stable latch mechanism for high-speed signal transmission.

Innovation Solution

A cable connector assembly with a latch mechanism comprising a latch member and a pulling member, where the latch member has hook portions that latch with the complementary connector and shaft pins received in shaft holes, allowing for easy insertion and separation through a pivoted connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a latch mechanism is used to secure the complementary connector, then connection stability is improved, but the ease of insertion and separation deteriorates

Engineering Contradiction:

Improveconnection stabilityVSAvoidease of insertion and separation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The latch member is designed to be movable rather than fixed, allowing it to dynamically transition between latched and unlatched states. The pulling member enables the latch member to move from an initial position (secured) to a released position (unsecured), making separation easy while maintaining connection stability during use.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The latch mechanism is divided into separate functional components: a latch member for securing, a pulling member for actuation, and shaft pins for pivoting. This segmentation allows each component to perform its specific function efficiently, with the pulling member independently controlling the latch member's state without compromising the overall connection stability.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If a fixed latch structure is used, then structural simplicity is improved, but the flexibility of operation deteriorates

Engineering Contradiction:

Improvestructural simplicityVSAvoidflexibility of operation

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The position of the latch member changes as a parameter to enable different operational states. By changing the position parameter of the latch member (secured vs. released), the system achieves operational flexibility without requiring complex mechanisms, maintaining structural simplicity while enabling easy insertion and separation.

AI summary

A cable connector assembly includes a housing and a plurality of conductive contacts located in the housing. The housing defines a receiving room therein and a mating port through which a complementary connector is inserted into the receiving room. A plurality of cables electrically connects with the conductive contacts. A latch mechanism is assembled to an outside face of the housing and includes a latch member and a pulling member connecting with the latch member. The latch member defines a pair of hook portions inserted into the receiving room from the outside face and latching with the complementary connector. The latch member further defines a pair of shaft pins and the pulling member defines a pair of shaft holes. The shaft pins are pivotedly received in the shaft holes.
