Plug Connector Exposed Terminals for Sheet Cable Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for sheet-shaped cables, such as flexible printed circuits, require complex and labor-intensive processes for connecting terminal members to the cables and storing them within a housing, making the connection process cumbersome and costly.
Innovation Solution
A plug connector and connector set design that includes a plug housing with exposed connection sections for plug terminals, allowing for easy alignment and connection with sheet-like cables, facilitated by guide grooves and locking mechanisms, which simplifies the connection process and reduces production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal members are stored inside a housing and connected to FPC by soldering or press fitting, then electrical connection is established, but the connection process becomes complex and labor-intensive
Solution Approach 1:
The invention extracts the terminal member from the housing and connects it directly to the FPC external connection portion without storing it inside the housing. This eliminates the complex steps of storing terminal members in the housing and performing soldering or press fitting operations, while still establishing reliable electrical connection between the terminal member and FPC
Solution Approach 2:
The terminal member is preliminarily connected to the FPC external connection portion before the FPC is inserted into the housing. This preliminary connection simplifies the overall assembly process by eliminating subsequent soldering or press fitting steps, reducing labor intensity while maintaining electrical connection reliability
2Reliability
If terminal members are stored inside housing, then electrical connection is established, but production cost increases
Solution Approach 1:
The invention removes the terminal member from the housing storage configuration and implements direct connection to FPC. This simplification reduces manufacturing complexity and labor requirements, thereby lowering production costs while maintaining reliable electrical connection functionality
3Ease of operation
If connection sections are exposed from plug housing, then alignment and connection with sheet-like cables is simplified, but housing structure becomes more complex
Solution Approach 1:
The invention positions the connection section to extend in a direction perpendicular to the main body of the plug connector, creating an exposed external connection portion. This dimensional arrangement allows for simplified alignment and connection with sheet-like cables while the housing structure adapts to accommodate this extended configuration

AI summary
A plug connector of the present disclosure includes a plug housing and a plurality of plug terminals stored in the plug housing. This plug connector is fitted in a receptacle connector having a receptacle terminal, and is connected to a cable having a sheet shape and including a cable terminal, thereby establishing electrical connection between the receptacle terminal and the cable terminal. Each of the plug terminals has a contact section and a connection section. The contact section is contactable with the receptacle terminal, and the connection section is connectable to the cable terminal. In a state in which the plug connector is fitted in the receptacle connector, the connection section is disposed such that the connection section is exposed from the plug housing.
