Problem
Existing plug connectors for flat signal-transmission mediums require multiple processes and components, leading to complexity and potential backlash issues during attachment, which complicates efficient and reliable connection.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional plug connector uses multiple processes (setting process of flat signal-transmission medium, attachment process of conductive shell, adding process of fixing means), then the flat signal-transmission medium can be securely fixed, but the manufacturing complexity increases and productivity decreases
Solution Approach 1:
The patent combines the setting process, attachment process, and fixing process into a single integrated operation. The conductive shell is designed with an elastic pawl that automatically engages with the flat signal-transmission medium during insertion, eliminating the need for separate fixing means and multiple manufacturing steps while ensuring reliable fixation.
Solution Approach 2:
The elastic pawl in the conductive shell performs self-service by automatically engaging with and holding the flat signal-transmission medium without requiring external fixing means. The pawl's elastic deformation allows it to flex during insertion and then lock into place, providing automatic securing functionality.
2Reliability
If a traditional plug connector uses multiple processes and fixing means, then the flat signal-transmission medium can be fixed, but the number of components and device complexity increases
Solution Approach 1:
The patent merges the functions of the conductive shell and fixing means into a single integrated component. The elastic pawl is formed as an integral part of the conductive shell, eliminating the need for separate fixing means and reducing the overall number of components while maintaining reliable fixation.
Solution Approach 2:
The conductive shell serves multiple functions: it provides electromagnetic shielding, structural support, and automatic fixation through the elastic pawl. This multi-functionality reduces the need for additional specialized components, simplifying the overall device structure.
3Ease of manufacture
If the flat signal-transmission medium is inserted into the conductive shell, then the attachment process is simplified, but backlash may occur without proper engagement mechanism
Solution Approach 1:
The elastic pawl is designed to dynamically respond to the insertion of the flat signal-transmission medium. During insertion, the pawl elastically deforms to allow smooth passage, then automatically locks into place to prevent backlash. This dynamic behavior ensures both easy attachment and reliable connection stability.
Solution Approach 2:
The elastic pawl is pre-configured to exert a holding force on the flat signal-transmission medium. This preliminary anti-action prevents backlash by continuously applying a restraining force that counteracts any potential movement or loosening during operation.

AI summary
To make it possible to connect a flat signal-transmission medium to a plug connector efficiently and surely with a simple configuration where the number of components are reduced. In a conductive shell having a medium receiving space in which a terminal portion of the flat signal-transmission medium is inserted, a retaining engaging pawl which is engaged with a part of the flat signal-transmission medium inserted into the medium receiving space and holds the flat signal-transmission medium is made to be provided in a manner where elastic displacement is possible, and the retaining engaging pawl is configured to be engaged with a part of the flat signal-transmission medium owing to an elastically returning bias force of the retaining engaging pawl, and thereby, only by inserting the flat signal-transmission medium into the medium receiving space of the conductive shell, the flat signal-transmission medium is held without a backlash in the conductive shell owing to a engagement force of the retaining engaging pawl, and attaching of the flat signal-transmission medium is performed easily and satisfactory.
