Coaxial Connector Shell Merging Contact and Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coaxial connectors have complex assembly steps for connecting the outer conductor of coaxial cables, leading to increased manufacturing costs and reduced miniaturization due to the need for additional components and assembly steps.
Innovation Solution
A coaxial connector design featuring a conductive shell with a first shell portion for contact with a mating connector, a second shell portion for connecting to the ground conductor, and positioning and fixing mechanisms to simplify the assembly process and reduce component count, allowing for electrical connection between a connection object with a flat plate portion and a mating connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connection terminal is provided for contact with a mating contact of a mating connector, then electrical connection is achieved, but the number of components increases and manufacturing cost increases
Solution Approach 1:
The patent merges the connection terminal function with the shell structure by making the shell itself conductive. The shell serves dual purposes: as the structural housing and as the electrical contact element that engages with the mating connector, thereby eliminating the need for a separate connection terminal component.
Solution Approach 2:
The shell is designed to perform multiple functions simultaneously: it provides mechanical protection, serves as the structural housing, and acts as the electrical contact element. This multi-functionality reduces the overall component count while maintaining reliable electrical connection capabilities.
2Reliability
If a connection terminal and separate components are used for electrical connection, then electrical connection is achieved, but the manufacturing cost increases
Solution Approach 1:
The patent combines the shell and connection terminal into a single integrated component. This reduction in part count directly lowers manufacturing costs by reducing material expenses, assembly operations, and quality inspection steps while maintaining the electrical connection function.
Solution Approach 2:
The conductive shell performs multiple functions including structural support, insulation housing, and electrical contact. This multi-functionality reduces the total bill of materials and simplifies the manufacturing process, thereby reducing overall production costs.
3Reliability
If multiple separate components are used for connector assembly, then electrical connection is achieved, but the connector size increases and miniaturization is hindered
Solution Approach 1:
The patent integrates the connection terminal within the shell structure, making the terminal an integral part of the shell rather than a separate component. This integration significantly reduces the overall connector volume and enables miniaturization while maintaining reliable electrical connection.
Solution Approach 2:
The shell is designed to perform multiple functions within a compact form factor. By making the shell itself conductive and structurally integrated, the design achieves reliable electrical connection without requiring additional space for separate components, thereby enabling miniaturization.

AI summary
A coaxial connector is adapted to hold a connection object having a ground conductor and a signal conductor and is adapted to be fitted to a mating connector. The coaxial connector has a shell for holding the connection object. The shell comprises a first shell portion having a barrel-shaped shell contact portion, a second shell portion having shell connecting portions, positioning portions for positioning the connection object so that a contact portion of the signal conductor of the connection object is located inside the barrel-shaped shell contact portion as seen in a fitting direction of the coaxial connector and the mating connector, and fixing portions for fixing the connection object.
