Solution Overview

Problem

Heavy-duty connectors require cables to be bent during installation, which can damage them and limit their use to only bendable cables, increasing maintenance costs and reducing their applicability.

Innovation Solution

An adapter connector assembly that allows a cable entry system to be used with heavy-duty connectors, enabling cables to be mounted in a normal linear state, accommodating both bendable and unbendable cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cables are bent during installation to fit through the top opening of the upper shell, then the cables can be connected and secured to the inserts, but the cables are susceptible to damage and the connector becomes unavailable for thicker or unbendable cables

Engineering Contradiction:
Improvecable installationVSAvoidcable service life
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connector is divided into two separate components: the heavy-duty connector body and the adapter connector assembly. This segmentation allows the adapter to provide a separate cable entry path through its housing, eliminating the need to bend cables through the connector's top opening. The adapter's housing with first and second opening ends creates an alternative installation route that preserves cable integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adapter connector assembly acts as an intermediary component between the heavy-duty connector and the cable entry system. It mediates the connection by providing a mounting frame that can be assembled with either a cable joint or a cable entry system, thereby enabling cables to enter the connector without bending while still maintaining secure electrical connection through the inserts.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If cables are bent for a long period of time during installation, then they can be aggregated together to come out of the top opening, but the cables are susceptible to damage and maintenance cost increases

Engineering Contradiction:
Improveinstallation efficiencyVSAvoidcable damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The adapter connector assembly is pre-configured with a mounting frame and housing structure that establishes a proper cable entry path before cable installation. By preliminarily setting up the adapter with its opening ends and cavity, cables can be directly routed through the housing without requiring bending or aggregation, thereby preventing damage from the outset.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If a cable joint is used to sleeve the cables at the top opening, then the cables can be secured, but the connector becomes unavailable for thicker cables and unbendable cables

Engineering Contradiction:
Improvecable type compatibilityVSAvoidinstallation structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adapter connector assembly is designed with universal adaptability by providing a mounting frame that can accommodate different cable entry configurations. The housing with its cavity and opening ends can work with various cable types including thicker and unbendable cables, while still maintaining compatibility with the heavy-duty connector's electrical connection system through the inserts.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present disclosure provides an adapter connector assembly, an electrical connector plug, and an electrical connector kit. One end of the adapter connector assembly is configured for adaptive installation of a cable entry system, and the adapter connector assembly includes a mounting frame and a housing that can be assembled together. An upper portion of the mounting frame is configured to be assembled with the cable entry system, and the housing has a first and second open ends opposite each other and a cavity extending between the first and second open ends and for accommodating at least part of the mounting frame. The adapter connector assembly provided herein enables the combined use of the cable entry system and a connector, and thus broadens a cable application scope of the connector and increases a service life of cables mounted to the connector.
