Solution Overview

Problem

Existing circular connectors face challenges in providing secure and easy-to-assemble shielding, particularly for connectors subjected to mechanical stresses and requiring reliable electrical contact.

Innovation Solution

A circular connector design featuring a shield connection with receiving slots and a collar-shaped or ring-shaped structure that allows the cable shield to be partially routed through, ensuring secure mechanical and electrical contact without crimping, and a method for assembly that simplifies the installation process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional crimping methods are used to secure cable shielding, then secure mechanical contact is achieved, but assembly complexity and difficulty increase

Engineering Contradiction:
Improveshielding contact reliabilityVSAvoidassembly ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the traditional crimping mechanical system with a slot-based routing system. The cable shielding is guided through slots in the connector housing, eliminating the need for crimping tools and operations while maintaining secure mechanical contact and shielding reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The slots act as intermediaries between the cable shielding and the connector housing. Instead of directly crimping the shielding to the housing, the slots provide a guided pathway that secures the shielding in place, simplifying the assembly process while ensuring reliable contact.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If cable shielding is securely fixed using traditional methods, then mechanical stability is improved, but assembly time increases

Engineering Contradiction:
Improveshielding mechanical stabilityVSAvoidassembly time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The slots are pre-formed in the connector housing during manufacturing, so no additional assembly steps are needed to create the shielding pathway. The cable shielding is simply routed through the pre-existing slots, maintaining mechanical stability while reducing assembly time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent substitutes time-consuming crimping operations with a simple routing-through-slots operation. This mechanical substitution dramatically reduces assembly time while maintaining the stability of the shielding connection.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If complex shielding assembly methods are used, then shielding reliability is improved, but device complexity increases

Engineering Contradiction:
Improveshielding connection reliabilityVSAvoidassembly process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex crimping operation from the assembly process and replaces it with simple slot routing. The slots are integrated into the housing structure, eliminating the need for separate crimping mechanisms or tools, thus reducing device complexity while maintaining shielding reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The complex mechanical crimping system is replaced with a simple geometric feature (slots) that guides and secures the cable shielding. This substitution dramatically reduces assembly process complexity while maintaining reliable shielding connections.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A circular connector (1) has a plug end (10) designed for making a plug connection. A cable (100) with a cable shield (102) extends from the circular connector (1) at one cable end (20) in a cable routing direction (K). A shield connection (30) mechanically and/or electrically contacts the cable shield (102) of a cable section (101) of the cable (100) located inside the circular connector (1). The shield connection (30) has at least one receiving slot (33) through which the cable shield (102) of the cable section (101) is at least partially passed.
