Solution Overview

Problem

Existing plug connectors for high-speed signal transmission have complex configurations and difficult latching mechanisms, making them cumbersome to operate.

Innovation Solution

A plug connector with a simplified latching mechanism featuring a latch and puller design, where the puller's actuator and operator work together to easily move the latch between latched and released positions through rearward sliding, allowing for straightforward latching and releasing operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a resilient beam is added to the metal shell to resist the driver, then the driver can be rotated to operate the latching mechanism, but the configuration becomes complicated and the operation becomes difficult

Engineering Contradiction:
Improvelatching mechanism operationVSAvoidlatching mechanism configuration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts and removes the resilient beam from the metal shell, eliminating the complex rotational driver mechanism. Instead, a simplified linear puller mechanism is used that directly pulls the latch without requiring resilient beams or rotational motion, thereby reducing device complexity while maintaining ease of operation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a resilient beam to resist and enable rotation, the invention inverts the approach by using a direct linear pulling action on the latch. The puller mechanism pulls the latch directly rearward without requiring rotational motion or resilient resistance, simplifying both the configuration and operation.

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If a complex driver and latch structure with multiple components is used, then the latching function can be achieved, but the configuration becomes clumsy and operation becomes difficult

Engineering Contradiction:
Improvelatching functionVSAvoidlatching mechanism configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The latching mechanism is segmented into distinct functional components: the latch with claw and bar section, and the separate puller with actuator and operator. This segmentation allows each component to perform its specific function simply - the latch provides the latching function while the puller provides the releasing function, reducing overall complexity while maintaining reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The latch mechanism is designed to be self-latching through the engagement of the claw with the complementary connector, requiring no additional resilient beams or complex driving mechanisms. The puller simply needs to pull the operator rearward to release the latch, allowing the system to maintain its latching function through simple, reliable mechanical engagement rather than complex active control.

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The simplified latching mechanism enables easy operation and reliable latching of complementary connectors, with the mechanism returning to the latched position via resilient restoring force, ensuring efficient high-speed signal transmission.

Implementation Method 1

a resilient portion extending forwardly across the receiving recess and having a free end connected with the puller 42. When the actuator 422 is released, the resilient portions restore themselves from the released position to the latched position.

AI summary

A plug connector (100) mating with a complementary connector includes a housing (1) and a latching mechanism (4) having a latch (41) and a puller (42). The latch includes a latching portion (411) provided with a claw (4110), a bar section (412) secured in the base, and a connecting portion (413) having a forwardly extending abutting portion (4133). The puller includes an actuator (422) and an operator (421) supported on the bar section and having an engaging portion (4217) engaged with the abutting portion. The operator slides rearwardly, in response to a rearward movement of the actuator, to upwardly and rearwardly move the engaging portion together with the abutting portion to thereby lift the claw from a latched position to a released position.
