Solution Overview

Problem

Conventional RF compression connectors have complex internal clamping mechanisms that complicate field installations and reduce efficiency, necessitating a simpler yet reliable and robust connection solution.

Innovation Solution

A clamp assembly with first and second arcuate segments that circumscribe the coaxial cable, featuring outward and inward barbs to secure the connector body to the cable, ensuring a robust mechanical and electrical connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional internal clamping mechanisms are used in RF compression connectors, then robust compression of conductors is achieved, but device complexity increases and field installation becomes complicated

Engineering Contradiction:

Improverobust compression connectionVSAvoidclamp mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The clamp assembly is divided into multiple arcuate segments (first and second segments) that can be assembled separately around the coaxial cable. Each segment contains retention members that engage with the cable and connector body, allowing for simplified field installation while maintaining robust compression through the distributed clamping action of multiple segments

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of using complex internal clamping mechanisms that require assembly from the inside out, the clamp assembly uses outwardly and inwardly projecting retention members that engage with the cable and connector body from the outside, simplifying the installation process while achieving reliable compression

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If conventional clamping mechanisms are used, then reliable electrical connection is achieved, but installation time and complexity increase

Engineering Contradiction:

Improveelectrical connection reliabilityVSAvoidfield installation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The clamp assembly is segmented into multiple arcuate sections that can be quickly assembled around the cable without requiring complex internal mechanisms. The segments work together to provide immediate electrical contact through the conductive clamp body, reducing installation time while ensuring reliable grounding

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The retention members are designed to automatically engage with the coaxial cable and connector body upon assembly of the clamp segments. The outwardly and inwardly projecting barbs self-align and secure the connection without requiring additional adjustment or complex internal mechanisms, enabling rapid field installation

Inventive Principle:

Principle #25Self-service

AI summary

An RF compression connector includes a simplified clamp mechanism having a common clamp base, and a plurality of segments disposed on the common clamp base wherein the segments include alternating first and second retention members disposed along the circumference of the clamp, wherein each of the first retention members has an outwardly projecting shoulder to engage a connector body and each of the second retention members includes an inwardly projecting shoulder to engage an outer jacket of a coaxial cable connector. The first and second retention members of the clamp mechanism inhibit separation of the connector body relative to the coaxial cable.
