Insulation Displacement Terminal Aperture Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insulation displacement systems (IDS) face challenges in maintaining a stable and compressed state of electrical wire bundles, leading to potential conductor migration and reduced current flow due to elastomeric deformation and vibration, which affects the reliability and even power distribution.
Innovation Solution
The IDS employs a configuration of two insulation displacement terminals with slots that are oriented oppositely to each other, forming a closed adjustable aperture that maintains the wire bundle in a compressed state, preventing conductor migration and increasing the terminal-to-wire interface area for enhanced current flow and power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional open slot IDS is used, then the cable can be easily inserted, but the wire bundle cannot maintain a stable compressed state due to elastomeric deformation
Solution Approach 1:
The single open slot is divided into two opposing slots that form a closed aperture when mated together. This segmentation allows the wire bundle to be compressed and held stable by the opposing slot walls, preventing elastomeric deformation while maintaining ease of insertion through the open aperture design.
Solution Approach 2:
The closed aperture formed by two opposing slots creates a nested structure that confines the wire bundle within a compressed space. The aperture acts as a container that maintains the compressed state of the wire bundle, preventing relaxation and migration.
2Ease of operation
If the slot is open, then insertion is easy, but conductors can migrate up the throat of the slot
Solution Approach 1:
The open slot is segmented into two opposing slots that form a closed aperture when mated. This creates a contained space that prevents conductor migration while maintaining easy insertion through the open aperture, as the closing action occurs after insertion.
Solution Approach 2:
The harmful open throat of the slot is extracted by closing it with an opposing slot to form a closed aperture. This removes the migration path for conductors while preserving the insertion function through the aperture opening.
3Stability of the object's composition
If the wire bundle is not compressed, then elastomeric deformation occurs, but compression increases vibration sensitivity
Solution Approach 1:
The closed aperture provides dynamic support to the compressed wire bundle, allowing it to maintain compression while resisting vibration-induced displacement. The opposing slot walls work together to stabilize the bundle under vibrational stress.
Solution Approach 2:
Two opposing slots are merged to form a closed aperture that simultaneously provides compression and vibration resistance. The combined structure of the mated terminals creates a stable environment that addresses both insulation integrity and vibration sensitivity.
4Device complexity
If a single terminal is used, then the structure is simple, but the terminal-to-wire interface area is limited
Solution Approach 1:
Two terminals are merged in a mated configuration with opposing slots that form a closed aperture. This merging doubles the terminal-to-wire interface area compared to a single terminal, as both slot walls contact the wire bundle, while maintaining structural simplicity through standardized mated terminal design.

This configuration ensures a robust and reliable electrical connection by maintaining the wire bundle in a compressed state, reducing the harmful effects of vibration and facilitating even power distribution among the wires, thereby improving the overall efficiency and stability of the electrical connection.
Implementation Method 1
as the insulated cable is pressed into the slot, the edges of the slot cut into the insulation surrounding the electrical conductor(s) and displace the insulator
Implementation Method 2
the edges of the slot cut into the insulation surrounding the electrical conductor(s) and displace the insulator
Implementation Method 3
as the exposed electrical conductor continues to travel into the slot, making contact with the electrically conducting edges of the slot

AI summary
An insulation-displacement system that comprises a first insulation-displacement terminal (IDT) adapted to receive in a mating configuration a second IDT. The first IDT comprises a first plate that includes a base edge, and a slot configured to receive an electrical conductor surrounded by an insulator and displace the insulator. The slot extends towards the center of the first plate from a second edge located opposite the base edge.
