Solution Overview
Problem
Existing coaxial connectors with shielding shells face challenges in production efficiency and cost due to complex assembly processes and mold requirements, leading to increased production costs and assembly difficulties.
Innovation Solution
A coaxial connector design featuring a shielding shell formed through one-time molding with a cavity created by bending a cover plate, simplifying the mold structure and assembly process, and incorporating a wire holder with ribs and notches for secure cable connection, reducing the need for multiple molds and assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separated design is applied on shielding shell and holding device, then structure of parts is simplified, but number of molds increases and production cost increases
Solution Approach 1:
The patent combines the shielding shell and holding device into a single integrated component. The holding arms are directly formed as part of the shielding shell structure, eliminating the need for separate holding device components and multiple molds, thereby reducing manufacturing cost while maintaining structural simplicity.
Solution Approach 2:
The shielding shell is designed to perform multiple functions: it provides electromagnetic shielding, structurally supports the connector, and incorporates holding arms that secure the coaxial cable. This multi-functional design eliminates the need for separate dedicated holding device components.
2Ease of manufacture
If once molding technique is used for shielding shell, then number of molds is reduced, but mold structure becomes more complex
Solution Approach 1:
The once-molded shielding shell is designed with segmented functional zones: a main body portion for shielding, integrated holding arms for cable support, and a flat portion for structural connection. This segmentation allows the complex multi-functional component to be manufactured in one piece while maintaining manufacturing feasibility through logical functional division.
3Manufacturing precision
If complex assembly process is used, then connection precision is improved, but production efficiency decreases
Solution Approach 1:
The holding arms are pre-formed as integral parts of the shielding shell during the molding process, with predetermined geometries that ensure proper positioning and securing of the coaxial cable. This preliminary formation of structural features eliminates the need for complex post-assembly operations while maintaining connection precision.

AI summary
The present invention relates to a coaxial connector, more particularly relates to a coaxial connector with shielding shell that comprises a main body, a flat portion connected to the main body and a wire holder on the rear end of the flat portion. The main body includes a pair of holding arms and a receiving hole for receiving the cylinder portion of the insulating housing. The flat portion has a front end and a back end, the front end receives the cylinder portion and supports the main body after the main body being bent toward to the flat portion, and there is a cavity formed in the center of the back end through bending over a cover plate, the bending arms bend inward to cover the insulating housing and holding arms from outside.
