Coaxial Connector Sandwiching Flat Plate Connection Object
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial connectors are not suitable for connecting flat plate-like objects due to complex shield wire assembly, large size, and increased number of assembly steps.
Innovation Solution
A coaxial connector design featuring a contact and shell structure that sandwiches a flat plate-like connection object between a connecting portion of the contact and a shell connecting portion, allowing for simultaneous connection of signal and ground conductors with reduced steps, thickness, and length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional coaxial connector is used for connecting flat plate-like objects, then the connection structure is established, but the connecting operation becomes complicated and the number of assembly steps increases
Solution Approach 1:
The patent combines the shield wire connection function with the main connector body by integrating the shield wire into the housing structure. The housing directly contacts the ground conductor of the flat plate-like object, eliminating the need for separate shield wire assembly steps and simplifying the overall connection process.
Solution Approach 2:
The connector housing serves multiple functions: it provides mechanical support, houses the contact element, and simultaneously acts as the shield wire connection component by directly contacting the ground conductor. This multi-functionality reduces the number of separate components and assembly steps required.
2Reliability
If a conventional coaxial connector is used for connecting flat plate-like objects, then the connection structure is established, but the thickness and length of the connector become large
Solution Approach 1:
The patent adapts the connector design from a traditional cylindrical form factor to a flat plate-like configuration that matches the geometry of the connection object. The contact element and housing are arranged in a planar configuration rather than extending axially, reducing the thickness and length of the connector while maintaining reliable electrical connection.
Solution Approach 2:
The connector design is optimized locally for flat plate connection by positioning the contact element and housing in a compact arrangement that matches the specific geometry of the flat plate-like object. The shield wire connection is integrated at the appropriate location on the housing to achieve reliable grounding without increasing overall dimensions.
3Adaptability or versatility
If a conventional coaxial connector is used for connecting flat plate-like objects, then the connection structure is established, but the number of assembly steps increases
Solution Approach 1:
The shield wire is pre-integrated into the housing structure during manufacturing, so that when the connector is assembled to the flat plate-like object, the shield wire connection is already in place. This preliminary integration eliminates separate assembly steps for shield wire installation and improves production efficiency.
Solution Approach 2:
The connector is divided into distinct functional components (contact element, housing, shield wire) that are designed to assemble in a straightforward sequence. The modular design allows each component to be manufactured independently and then assembled in a minimal number of steps, improving overall assembly efficiency.

AI summary
A coaxial connector includes a contact, a housing, and a shell. The contact includes a contact portion adapted to be connected to a mating contact of a mating connector and a connecting portion adapted to be connected to a signal conductor. The shell includes a first shell portion having a shell contact portion adapted to be connected to a mating shell of the mating connector and a second shell portion having a shell connecting portion adapted to be connected to a ground conductor. When connecting to a connection object, by sandwiching the connection object between the connecting portion of the contact and the shell connecting portion of the shell, the contact portion of the contact is connected to the signal conductor while the shell contact portion of the shell is connected to the ground conductor.
