Side-Loaded RF Connector Assembly for PCB Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an RF plug connector system that can be assembled to a circuit board in a cost-effective and reliable manner and mated with RF cable connectors in a similar fashion, addressing the inefficiencies of conventional methods which often involve individual soldering and complex assembly processes.
Innovation Solution
The RF connector system includes a receptacle connector assembly with side-loading capabilities and a plug connector assembly, where RF receptacle and plug connectors are housed within cavities and feature dielectric bodies for shielding, allowing for simultaneous termination and easy mounting to a circuit board, with features like retention clips and side openings for efficient assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RF plug connectors are individually soldered to the circuit board, then reliable electrical connection is achieved, but assembly time and manufacturing complexity increase
Solution Approach 1:
Multiple RF plug connectors are integrated into a single assembly unit that can be soldered to the circuit board as one component. The housing contains multiple connector cavities, and the assembly includes multiple RF plug connectors mounted within the housing, allowing simultaneous attachment to the circuit board rather than individual soldering of each connector.
2Manufacturing precision
If multiple RF connectors are assembled individually, then precise positioning is achieved, but assembly complexity and cost increase
Solution Approach 1:
The assembly is segmented into modular components: a housing with multiple connector cavities, RF plug connectors with standardized mounting features, and integrated retention mechanisms. Each connector cavity is pre-formed with precise positioning features, and retention clips or lugs provide automatic positioning and securing, eliminating the need for complex manual assembly procedures.
3Reliability
If conventional RF connector assemblies are used, then electrical shielding is maintained, but assembly and maintenance difficulty increase
Solution Approach 1:
The assembly incorporates dynamic retention features such as spring-loaded retention clips or snap-fit lugs that allow for easy insertion and removal of RF plug connectors. These retention mechanisms provide secure holding during operation while enabling quick replacement for maintenance or reconfiguration, transforming a static, permanent assembly into a dynamically accessible one.
