Connector With Orthogonal Flat Cable Drawing and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors with drawing-out portions for flat cables suffer from low airtightness, leading to potential water intrusion and limited flexibility in circuit design due to the need for complex terminal shapes to connect multiple conductors.
Innovation Solution
A connector design featuring a housing with a fitting portion, terminals, and a holder, where the flat cable is drawn out orthogonally, and sealed with a sealing material that integrates with the inner and outer peripheries of the drawing-out portion, allowing for improved waterproofing and simplified circuit design by enabling terminals to be placed across multiple conductors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the flat cable is drawn out in the fitting direction of the housing, then the connection between terminals and conductors is simplified, but the waterproof performance of the drawing-out portion deteriorates
Solution Approach 1:
The patent changes the drawing-out direction of the flat cable from the fitting direction (longitudinal dimension) to a direction orthogonal to the fitting direction. This dimensional change allows the sealing material to effectively seal the drawing-out portion while maintaining simple terminal shapes that connect to conductors in the orthogonal arrangement.
2Adaptability or versatility
If a single terminal is arranged at a corresponding single conductor in the flat cable, then the terminal shape is simple, but the circuit design flexibility deteriorates
Solution Approach 1:
By arranging conductors in the width direction of the flat cable and drawing the cable out orthogonally, the patent enables terminals to access multiple conductors without requiring complex three-dimensional routing. This orthogonal arrangement provides circuit design flexibility while maintaining simple terminal geometries.

AI summary
A connector includes: a housing with a fitting portion; a terminal accommodated in the housing, one end side of the terminal being arranged in the fitting portion; a flat cable drawn out of a drawing-out portion of the housing, provided with conductors connected to the other end of the terminal; and a holder integrally provided with the terminal on the other end side of the terminal, accommodated in the drawing-out portion, in which a connection portion of the terminal and the flat cable is arranged. The flat cable is draw out of the drawing-out portion in a direction orthogonal to a fitting direction of the housing. The terminal is placed across the conductors at the connection portion. The drawing-out portion is closed with a sealing material. The sealing material is integrally provided with an inner periphery of the drawing-out portion and an outer periphery of the flat cable.
