Hood Element Cable Core Positioning and Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for contacting cable cores on printed circuit boards are complex and not easily automatable, requiring multiple steps and having stability issues due to plastic latching elements and complex manufacturing processes.
Innovation Solution
A device with a hood element and insulation displacement contacts where the cable core is directly inserted and positioned, with latching elements offset by 90° from the contacts on a single stamped metal base plate, allowing for simplified and automated assembly and enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If core guide elements and hood elements with specific openings are used to position cable cores, then the cable cores can be positioned and contacted, but the assembly becomes complex and difficult to automate
Solution Approach 1:
The patent combines the cable core positioning function and the contacting function into a single integrated hood element. The hood element directly receives the cable core through its opening and simultaneously provides the insulation displacement contact, eliminating the need for separate core guide elements and reducing assembly complexity while maintaining positioning accuracy.
Solution Approach 2:
The hood element serves multiple functions: it positions the cable core through its opening, provides insulation displacement contact through the integrated contact element, and secures the assembly through latching elements. This multi-functional design simplifies the overall structure and enables automated assembly.
2Ease of manufacture
If latching elements are made of plastic as in prior art, then the device can be manufactured, but the stability and resistance to breakage are insufficient
Solution Approach 1:
The patent uses a composite construction where the latching elements are made of metal (specifically brass or bronze) rather than plastic, providing superior strength and resistance to breakage. The metal latching elements are integrated with the hood element through a one-piece design, combining manufacturability with enhanced mechanical properties.
3Ease of operation
If insulation displacement contacts are embedded in plastic housing parts, then the device can be assembled, but the manufacturing process becomes complicated and stability is limited
Solution Approach 1:
The insulation displacement contact element is integrated directly into the hood element as a one-piece construction, eliminating the need for separate embedding processes. This reduces manufacturing complexity while maintaining ease of assembly, as the contact element is permanently secured within the hood element structure.
4Ease of manufacture
If multiple separate components are used for insulation displacement contacts and latching elements, then the device can be manufactured, but the production process is complex and automation is difficult
Solution Approach 1:
The hood element, insulation displacement contact element, and latching elements are formed as a single integrated component through a one-piece design. This eliminates the need for multiple separate manufacturing steps and assembly operations, enabling automated production while maintaining manufacturability of the individual functions.
