Insulation Displacement Connector Extension for Tool Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulation displacement connectors require more space and hinder packing density due to the need for special tools to wire them, which complicates their integration in compact telecommunications and data technology systems.
Innovation Solution
An extension is added between the insulation displacement contact and the pin contact to guide the insulation displacement contacts away from the printed circuit board, allowing for easier access with wiring tools while maintaining high contact density, and incorporating arcuate elements to support the contact elements and absorb switch-on forces, along with a guide element and latching lugs for increased stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If insulation displacement contacts are used without extensions, then contact density is high, but wiring tools cannot access the contacts properly
Solution Approach 1:
The patent introduces extensions that protrude from the housing in a direction perpendicular to the printed circuit board, creating a three-dimensional arrangement. This allows wiring tools to access the insulation displacement contacts from the front side of the housing without interfering with the compact layout on the circuit board, effectively resolving the contradiction between tool accessibility and contact density.
2Ease of operation
If extensions are added to insulation displacement contacts, then wiring tool access is improved, but the connector occupies more space
Solution Approach 1:
The contact structure is divided into distinct segments: the base contact element mounted on the circuit board, the housing that provides structural support and shielding, and the extensions that protrude for tool access. This segmentation allows each component to be optimized independently, minimizing the overall volume while ensuring proper tool accessibility.
Solution Approach 2:
The extensions are integrated within the housing structure rather than being separate components. The housing encloses the extensions and provides shielding, creating a nested arrangement where the extension functionality is contained within the overall connector volume, minimizing space occupation.
3Ease of manufacture
If contact elements are pushed in from the top, then assembly is simple, but contact elements may deform during insertion
Solution Approach 1:
The housing includes stops that define a predetermined insertion depth for the contact elements. These stops prevent over-insertion and provide cushioning at the correct position, ensuring that contact elements are inserted to the proper depth without excessive force that could cause deformation, while maintaining simple push-in assembly.
