Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connection structures for sheet-like wiring members and cables require complex sequential operations, resulting in poor workability and inefficiency.
Innovation Solution
A cable junction connector with two fittings that sandwiches a sheet-like wiring member between them, using insulation-displacement contacts and a crimping mechanism to establish an electrical connection with the cable through a single press operation, allowing for easy and secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional connecting member with hinge portion is used to connect conductive fabric and cable, then electrical connection and fixation are achieved, but the connection process requires complex sequential operations resulting in poor workability
Solution Approach 1:
The connector is divided into two separate fittings (first fitting with insulation-displacement contact and second fitting with crimping contact), each performing a specific function. This segmentation allows the connection process to be simplified while maintaining electrical connection capabilities.
Solution Approach 2:
The patent combines multiple connection functions (insulation displacement, crimping, and electrical connection) into a single integrated connector assembly that sandwiches the sheet-like wiring member between two fittings, eliminating the need for sequential hinge-folding operations.
2Productivity
If multiple sequential operations are performed to attach conductive fabric and fix cable, then reliable electrical connection is achieved, but the process time and operational complexity increase
Solution Approach 1:
The sheet-like wiring member is pre-positioned between the two fittings before the final crimping operation. The insulation-displacement contact is pre-configured to engage the conductor, allowing the entire connection to be completed in a single pressing motion without sequential steps.
Solution Approach 2:
The connector structure automatically performs multiple functions simultaneously during a single operation: the insulation-displacement contact strips insulation and makes contact, while the crimping contact secures the cable, all within one pressing action without requiring separate manual steps.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables a reliable and efficient electrical connection between the cable and the sheet-like wiring member with a single press operation, improving workability and ensuring a strong, secure fixation.
Implementation Method 1
A first fitting has an insulation-displacement contact which includes an open-ended slot. A direction in which the cable is forced into the open-ended slot is perpendicular to a direction in which the cable extends
Implementation Method 2
a cable junction connector with two fittings provided with a structure in which a sheet-like wiring member with a front surface on which a conductor is formed is sandwiched between the two fittings

AI summary
A cable connection structure includes a cable, a sheet-like wiring member, and a cable junction connector. The cable junction connector includes a first fitting and a second fitting. A connection portion of the first fitting and a connection portion of the second fitting interlock with each other in a state in which a part of a conductor formed on the sheet-like wiring member is sandwiched between a plate portion of the first fitting and a plate portion of the second fitting. The first fitting has an insulation-displacement contact which includes an open-ended slot. The cable is forced into the open-ended slot. A direction in which the cable is forced into the open-ended slot is perpendicular to a direction in which the cable extends and is parallel to a direction in which the part of the conductor is sandwiched between the plate portion of the first fitting and the plate portion of the second fitting.
