Solution Overview

Problem

Current coaxial cable connectors face challenges such as difficulty in assembly, potential damage to cables, high manufacturing costs, and inferior sealing and coupling performance under applied forces, necessitating an improved design that provides a secure and watertight connection.

Innovation Solution

A coaxial cable connector design featuring a coupler portion, a housing portion that moves axially to compress a conductive outer conductor engager, and resilient fingers that radially compress the outer conductor, eliminating the need for post-based crimping and enhancing the sealing and coupling performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If post-based crimping connectors are used, then mechanical connection is achieved, but assembly becomes difficult and cable damage occurs

Engineering Contradiction:
Improvemechanical connectionVSAvoidassembly
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The invention removes the grounding/retention post from the connector design, eliminating the complex multi-step crimping process that required specialized tools and alignment fixtures. The outer conductor engager directly engages the braided shield without needing a separate post insertion and crimping operation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces the mechanical post-based crimping system with a streamlined outer conductor engager that directly engages the braided shield through a simplified compression mechanism, eliminating the need for specialized crimping tools and alignment fixtures.

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

2Reliability

If post-based crimping connectors are used, then grounding connection is achieved, but manufacturing cost increases

Engineering Contradiction:
Improvegrounding connectionVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention removes the separate grounding post component and its associated crimping tools and alignment fixtures, significantly reducing the number of parts and specialized equipment needed for manufacturing and assembly.

Inventive Principle:

AI summary

A connector for a coaxial cable includes a coupler portion configured to engage an interface port, a housing portion having a forward end configured to be disposed at least partially within the coupler portion, and an outer conductor engager portion made of a conductive material disposed within the housing portion. The housing portion includes a rearward end configured to receive the coaxial cable and is configured to move axially relative to a post that engages the outer conductor of the cable. An interior surface of the housing portion is configured to compress an insert of the post when the housing portion is moved axially relative to the post such that the outer conductor is compressed radially inward against an exterior surface of the insert of the post.
