Solution Overview
Problem
Existing measurement systems face challenges in achieving reliable and efficient radio-frequency (RF) and microwave signal transmission due to limitations in connector designs, which often result in high contact resistance and signal reflection, especially in coaxial connections.
Innovation Solution
A crushable connector interface is introduced, featuring a conductive housing with a raised deformable annulus that deforms upon adapter insertion, creating a larger contact area and improving impedance matching, thereby reducing contact resistance and enhancing signal transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rigid connector interfaces are used, then manufacturing is simple and structure is straightforward, but contact area is small leading to high contact resistance and poor impedance matching
Solution Approach 1:
The patent changes the physical state parameter of the connector interface from rigid to deformable. The raised deformable annulus is designed to undergo elastic deformation during insertion, transforming from a raised state to a compressed state that conforms to the adapter surface, thereby increasing contact area and improving impedance matching
Solution Approach 2:
The patent employs a flexible deformable annulus structure that can elastically deform under insertion force. This flexible element compresses to match the adapter's outer conductor surface, creating an extended contact area that reduces contact resistance and improves signal transmission reliability
2Reliability
If traditional rigid connector interfaces are used, then structure is simple, but contact area is insufficient leading to signal reflection
Solution Approach 1:
The patent modifies the mechanical property parameter of the connector interface by introducing a deformable annulus with controlled elasticity. This element deforms under insertion force to extend the contact area, achieving better impedance matching and reducing signal reflection without requiring complex multi-component designs
3Reliability
If traditional connector interfaces with small contact area are used, then manufacturing is easy, but contact resistance is high
Solution Approach 1:
The patent uses a flexible deformable annulus that elastically compresses during adapter insertion. This deformation extends the contact area between the connector and adapter, thereby reducing contact resistance and improving electrical connection reliability without adding complex manufacturing processes

The crushable connector interface increases the contact area and uniformity, leading to improved impedance matching, reduced signal reflection, and enhanced transmission efficiency in RF and microwave connections.
Implementation Method 1
a raised deformable annulus mounted on the flat annular surface. The raised deformable annulus is of a height such that an insertion of the adapter into the space deforms the raised deformable annulus to generate a physical contact connection between the flat annular surface and the adapter

AI summary
A connector is disclosed. The connector includes a conductive housing. The conductive housing includes a wall region enclosing a space for receiving an adapter. The conductive housing also includes an annular end piece extending radially inward from a first end of the wall region and terminating the space. The annular end piece includes a flat annular surface, and a raised deformable annulus mounted on the flat annular surface. The raised deformable annulus is of a height such that an insertion of the adapter into the space deforms the raised deformable annulus to generate a physical contact connection between the flat annular surface and the adapter.
