Coaxial Connector Assembly with Floating Module for Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial connectors face challenges in achieving a higher density of coaxial contacts while ensuring proper alignment during mating operations, which can lead to damage of signal pins if not aligned correctly.
Innovation Solution
The coaxial connector assembly features a connector module with floating movement within a mounting frame, allowing for lateral movement and alignment of coaxial contacts, and includes a backing plate to secure the module in place, enabling rear-loading of coaxial contacts and preventing axial movement, thus facilitating alignment and reducing the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the density of coaxial contacts is increased, then the quantity of contacts per unit area is improved, but the difficulty of aligning opposing connectors during mating increases
Solution Approach 1:
The connector body is designed to float within the mounting frame, allowing dynamic adjustment of position during mating operations. This floating capability enables the connector to self-align with mating connectors even when contact density is high, resolving the contradiction between increased contact quantity and alignment difficulty
Solution Approach 2:
The floating connector body automatically adjusts its position relative to the mounting frame during mating, enabling self-alignment without external intervention. This self-service mechanism allows high-density contacts to mate properly through natural positional adjustment during the connection process
2Quantity of substance
If the density of coaxial contacts is increased, then the quantity of contacts per unit area is improved, but the risk of signal pin damage during mating increases
Solution Approach 1:
The floating connector body provides dynamic positional adjustment during mating, preventing misalignment that could cause signal pin damage. This movement capability ensures that even with high contact density, the signal pins can accommodate minor positioning variations without damage
Solution Approach 2:
The floating mechanism acts as a cushioning element that absorbs misalignment stresses before they reach the signal pins. By allowing the connector body to move and self-align, the system prevents harmful forces from directly impacting the fragile signal pins during mating operations
3Stability of the object's composition
If the connector body is fixed rigidly in the mounting frame, then the stability of the connector position is improved, but the ability to align during mating operations deteriorates
Solution Approach 1:
The connector body is designed with floating capability within the mounting frame, transitioning from a rigid fixed position to a dynamically adjustable position. This allows the connector to maintain stability during normal operation while enabling alignment movements during mating operations, resolving the contradiction between position stability and alignment capability

AI summary
A coaxial connector assembly includes a connector module having a connector body having contact channels holding coaxial contacts and a mounting frame defining a passage having a recess that receives the connector body. The mounting frame has a pocket open to the recess and a backing plate removably received in the pocket. The backing plate is coupled to the mounting frame to at least partially block the recess. The mounting frame includes blocking surfaces and the backing plate includes a blocking surface defining a confined space oversized relative to the connector module to allow a limited amount of floating movement in the confined space in a lateral direction that is perpendicular to the mating axis.
