Push-On RF Connector Sleeve Structure for Faster Test Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RF connectors require time-consuming threading mechanisms for connection and disconnection, which hampers testing efficiency, especially during frequent usage.
Innovation Solution
A female type RF connector with a push-on connection mechanism that utilizes a conductive sleeve with springs and a dielectric layer, allowing for quick and easy insertion and removal from both cable and testing equipment, facilitated by a middle portion acting as a stop and an end cap to prevent sleeve removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threading mechanisms are used for connection and disconnection, then reliable electrical connection is achieved, but operator time and testing efficiency deteriorate
Solution Approach 1:
The connector is divided into two distinct parts: a threaded portion for secure attachment to testing equipment and a push-on portion for rapid cable connection. This segmentation allows each part to optimize for its specific function - threading for reliability and push-on for speed.
Solution Approach 2:
The connector transitions from a static threaded design to a dynamic hybrid design where the push-on portion can rapidly engage and disengage. The spring-loaded conductive sleeve provides dynamic mechanical force to maintain electrical contact during push-on operations.
2Strength
If threading mechanisms are used for connection, then secure fastening is achieved, but ease of operation deteriorates
Solution Approach 1:
The fastening mechanism is segmented into threaded fastening for equipment attachment and push-on fastening for cable connection. This allows the connector to provide strong secure fastening where needed while maintaining ease of operation for frequent cable changes.
Solution Approach 2:
The spring-loaded conductive sleeve automatically engages with the cable connector upon insertion and maintains electrical contact through its inherent mechanical force, eliminating the need for manual tightening or threading operations by the operator.
3Productivity
If push-on connection is implemented, then testing efficiency is improved, but device complexity increases
Solution Approach 1:
The connector structure is segmented into distinct functional portions - the threaded portion for equipment mounting and the push-on portion with conductive sleeve for cable connection. This segmentation allows the complex push-on mechanism to be contained in a specific section without complicating the entire connector design.
Solution Approach 2:
The conductive sleeve acts as an intermediary element between the push-on connection and the electrical contact. It provides the necessary mechanical force and electrical conductivity while simplifying the overall interaction between the cable connector and the RF connector body.

AI summary
A RF connector (200) is provided. The connector (200) includes a first socket member (102). The first socket member (102) includes a conductive sleeve (222) and end cap (700). The conductive sleeve (222) includes a top portion (408), a bottom portion (406), and a plurality of springs (218) connecting the top portion (408) and the bottom portion (406). A base (300A, 300B) inside the conductive sleeve (222) includes a first matching hole (216) configured to match to a first conductive pin (502, 606) of a first plug member (500, 600). The end cap (700) includes a base (702) and a lip (704). In a first position, the top portion (408) of the conductive sleeve (222) contacts the base (702) of the end cap (700) and is partially enclosed by the lip (704) of the end cap (700). The end cap (700) prevents the removal of the conductive sleeve (222) in the first position.
