Ultra-Low Profile Coaxial Connector With Lateral Pin Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current coaxial cable connectors and receptacles have a mated height that is too high for modern electronic devices, particularly in mobile devices where thinner designs are required.
Innovation Solution
The development of an ultra-low profile coaxial cable connector that achieves a mated height of less than 1.0 mm by implementing a lateral coupling mechanism between the coaxial cable inner conductor and the center pin of the coaxial receptacle, eliminating the need for rotational coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If conventional coaxial cable connector designs are used, then reliable signal transmission is achieved, but the mated height exceeds 1.0 mm which is too high for modern thin electronic devices
Solution Approach 1:
The patent transitions from rotational coupling (vertical dimension) to lateral coupling (horizontal dimension). The inner conductor and center pin are coupled laterally at the same vertical level, eliminating the need for rotational movement and reducing the vertical height requirement to less than 1.0 mm while maintaining electrical connection reliability
Solution Approach 2:
Instead of the conventional approach where the connector rotates onto the receptacle (rotational coupling), the patent inverts the coupling mechanism by having the inner conductor and center pin connect laterally in the same plane. This inversion of the coupling direction enables ultra-low profile design without sacrificing connection reliability
2Length of stationary object
If rotational coupling is used to connect the inner conductor to the center pin, then electrical connection is achieved, but the height dimension increases beyond acceptable limits for mobile devices
Solution Approach 1:
The patent extracts the rotational coupling mechanism from the design and replaces it with a lateral coupling mechanism. By removing the rotational element, the height dimension is reduced to less than 1.0 mm while the lateral coupling provides sufficient electrical connection without the complexity of rotational movement
Solution Approach 2:
The coupling mechanism moves from the vertical rotational dimension to the horizontal lateral dimension. The inner conductor and center pin are connected laterally at the same vertical level, eliminating the height increase associated with rotational coupling and simplifying the overall structure

AI summary
An ultra-low profile coaxial cable connector (i.e. plug) is provided that implements a lateral coupling of a coaxial cable inner conductor and center pin of a mating PCB-mounted coaxial receptacle. The overall height of a mating coaxial receptacle center pin is also reduced by way of a cutout in the receptacle ground ring as well as a cutout in a mating outer shell of the coaxial cable connector. The ultra-low profile coaxial cable connector achieves a reduction in mated height of less than 1.0 mm for both 1.13 mm diameter and 0.81 mm diameter coaxial cables. In both cases, the coaxial cable connector designs as discussed herein enable a further reduction in the total thickness of communication module boards to 1.25 mm, thereby meeting the high demands for thinner electronic device designs.
