Solution Overview

Problem

Conventional cable connectors in mobile communication and indoor coverage systems fail to ensure a stable and lasting connection of cable conductors and are prone to water seepage, leading to equipment damage.

Innovation Solution

An integrated compression connector design featuring a housing with opposing ends, a pin with an elastic end for engaging cable conductors, a threaded sleeve, and a cable clamp in an interference fit, along with additional sealing components like O-shaped rings and housings to prevent water ingress, forming a stable and waterproof connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional threaded connectors are used, then assembly is relatively simple, but connection stability and durability are poor

Engineering Contradiction:

Improveconnection stabilityVSAvoidconnector structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the connector body, cable clamp, and sealing components into an integrated compression connector structure. The housing includes an integrated cable clamp that is formed as one piece with the main body, eliminating separate threaded fasteners and improving connection stability while maintaining structural simplicity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The connector is pre-configured with compression elements and sealing rings in predetermined positions during manufacturing. The cable clamp is pre-shaped to engage the cable outer conductor, and sealing rings are pre-installed in grooves, allowing for rapid reliable assembly without complex field adjustments.

Inventive Principle:

Principle #10Preliminary action

2Object-affected harmful factors

If conventional split-structure connectors are used, then manufacturing is easier, but water sealing performance is poor

Engineering Contradiction:

Improvewater seepage resistanceVSAvoidconnector assembly

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent combines multiple sealing functions into the integrated housing structure. The cable clamp itself is designed as a sealing element that contacts the cable outer conductor, and additional sealing rings are integrated into grooves within the housing, creating continuous sealing paths without requiring separate waterproofing components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent employs flexible sealing rings made of elastomeric materials that can deform to conform to the cable outer conductor surface and fill gaps between components. These flexible sealing elements provide effective water sealing while accommodating manufacturing tolerances and cable variations.

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If conventional connectors are used, then installation is standard, but connection durability in harsh environments is poor

Engineering Contradiction:

Improveenvironmental protectionVSAvoidinstallation process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The compression connector is designed to self-seal and self-secure when installed. The compression element automatically engages the cable outer conductor and the cable clamp when compression force is applied, and the integrated sealing rings automatically contact the cable and housing surfaces to prevent water ingress without requiring additional sealing steps.

Inventive Principle:

Principle #25Self-service
