Coaxial Connector Integral Conductor Base Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for manufacturing coaxial connectors are complex and costly due to the need for separate fabrication of central and grounded conductors and precise insert molding, which can lead to suboptimal transmission characteristics.
Innovation Solution
A method involving the integral formation of a conductor base member with a signal terminal, grounded conductor, and connecting portion, followed by cutting to create separate components, which are then fixed to an electrically insulating housing, allowing for accurate positioning and reduced manufacturing steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate fabrication of central conductor and grounded conductor by punching and bending is performed, then manufacturing flexibility is improved, but the number of steps increases and manufacturing complexity worsens
Solution Approach 1:
The patent merges the central conductor and grounded conductor into a single integral conductor base member formed from one piece of electrically conductive material. This eliminates the need for separate fabrication steps (punching and bending) and subsequent assembly, reducing manufacturing complexity while maintaining the ability to form different conductor shapes and configurations.
Solution Approach 2:
The conductor base member is preliminarily formed with integrated central conductor and grounded conductor portions along with connecting portions before the final separation step. This preliminary integration simplifies the manufacturing process by establishing all conductor geometries and relative positions in a single forming operation rather than through multiple sequential steps.
2Ease of manufacture
If separate fabrication of central conductor and grounded conductor is performed, then component independence is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple conductor components into a single integral conductor base member, eliminating the need for separate fabrication processes, multiple material purchases, and separate handling operations. This integration directly reduces manufacturing cost while the subsequent separation process maintains the functional independence of individual conductor components.
3Manufacturing precision
If insert molding of resin is performed with high accuracy relative position setting, then electrical insulation is improved, but manufacturing complexity increases
Solution Approach 1:
The conductor base member is preliminarily formed with integrated central conductor and grounded conductor portions along with connecting portions before the final separation step. This preliminary integration simplifies the manufacturing process by establishing all conductor geometries and relative positions in a single forming operation rather than through multiple sequential steps.

AI summary
There are provided a connector having excellent transmission characteristics, and a method for manufacturing such a connector, by which a connector can be manufactured more easily than in the conventional techniques, and thus its manufacturing cost can be reduced. A conductor base member including central terminal portions to form signal terminals, a grounded conductor portion to form a grounded conductor, connecting portions for connecting between the central terminal portions and the grounded conductor portion so as to integrate them together is integrally formed with an electrically conductive material. Then, the conductor base member is integrally fixed to the housing, and the connecting portions are cut to configure the central terminal portions as the central terminals and configure the grounded conductor portion as the grounded conductor, thereby obtaining a plug.
