Solution Overview

Problem

The existing connector designs are prone to damaging the cable lead-out portions when the receptacle and plug connectors are mated and swung, leading to potential mechanical stress on the cables.

Innovation Solution

Incorporating a cable protection portion and a regulating portion that overlaps with the cable protection portion when the connectors are mated, which suppresses the movement of the cables and prevents damage to the lead-out portions by positioning the regulating portion above the cable protection portion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the receptacle connector and plug connector are mated with each other, then electrical connection is established, but the cable lead-out portions are damaged due to cable swinging

Engineering Contradiction:
Improveelectrical connectionVSAvoidcable lead-out portion
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

A cable protection portion is introduced as an intermediary component between the cable and the connector. This protection portion extends from the connector body and positions the cable in a protected state, preventing direct contact between the cable lead-out portion and potential damage sources during connector mating and cable swinging operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The cable protection portion is designed to pre-position and secure the cable before the connector mating operation occurs. By establishing the cable's protected position in advance, the system prevents damage that would otherwise occur during the subsequent mating and swinging operations.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the cable is allowed to move freely, then flexibility is maintained, but the cable lead-out portion is damaged when the connector is swung

Engineering Contradiction:
Improvecable flexibilityVSAvoidcable lead-out portion integrity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The cable protection portion provides localized protection specifically at the vulnerable lead-out portion of the cable. This selective protection allows the rest of the cable to maintain its flexibility and movement freedom, while only the critical lead-out area is constrained and protected from damage during connector swinging.

Inventive Principle:
Principle #3Local quality

AI summary

A second connector of an electronic device is mateable with and removable from a first connector along a front-rear direction. The second connector has a cable protection portion which is located on a protected portion of a cable to protect the protected portion. The cable is led out from the cable protection portion in a direction intersecting with the front-rear direction. The first connector has a receiving portion and a regulating portion. The receiving portion receives the cable protection portion at least in part in a state that the first connector is mated with the second connector. The regulating portion is located above the cable protection portion in an up-down direction and overlaps with the cable protection portion in the state that the first connector is mated with the second connector.
