Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Condensation in connectors used to connect flexible flat cables to circuit boards can lead to a reduction in insulation between conductor pads, which is difficult to prevent completely and increases the complexity of the connection process.
Innovation Solution
A connector assembly with a housing and partition portions made of an elastic material that are positioned between conductor lines to prevent insulation reduction, using a design that allows for easy insertion and connection while maintaining insulation even in the presence of condensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resin is supplied to block outside air from entering the connector, then insulation between conductor pads is improved, but the work involved in connecting the flat cable to the circuit board increases
Solution Approach 1:
The elastic partition portions automatically deform to contact the flat cable when inserted, creating moisture blocking partitions without requiring additional manual operations. The connector structure itself performs the moisture blocking function through the elastic deformation of partition portions, eliminating the need for separate resin supply operations.
Solution Approach 2:
The partition portions utilize elastic material properties to change their physical state from a relaxed position to a deformed contact position with the flat cable. This parameter change (elastic deformation) enables the partition to automatically adapt to the cable and block moisture without additional fastening or sealing operations.
2Reliability
If resin is supplied to block outside air from entering the connector, then insulation between conductor pads is improved, but the connection process becomes more complex
Solution Approach 1:
The elastic partition portions automatically deform to contact the flat cable when inserted, creating moisture blocking partitions without requiring additional manual operations. The connector structure itself performs the moisture blocking function through the elastic deformation of partition portions, eliminating the need for separate resin supply operations.
Solution Approach 2:
The partition portions utilize elastic material properties to change their physical state from a relaxed position to a deformed contact position with the flat cable. This parameter change (elastic deformation) enables the partition to automatically adapt to the cable and block moisture without additional fastening or sealing operations.
3Reliability
If the connector is designed to completely prevent condensation, then insulation is maintained, but the design becomes more complex and difficult to achieve
Solution Approach 1:
The connector interior is divided into multiple regions by the elastic partition portions, which create separate moisture blocking zones between adjacent conductor pads. This segmentation approach prevents moisture accumulation in specific high-risk areas without requiring a complete redesign of the entire connector structure.
Solution Approach 2:
The partition portions utilize elastic material properties to change their physical state from a relaxed position to a deformed contact position with the flat cable. This parameter change (elastic deformation) enables the partition to automatically adapt to the cable and block moisture without additional fastening or sealing operations.

AI summary
The housing of the connector has insertion paths into which flat cables can be inserted. The connector also has a plurality of partition portions, which are formed of an elastic material. The partition portions are arranged along the insertion paths. When the flat cables are inserted into the insertion paths, the partition portions are positioned between the two adjacent conductor lines.
