Insulating Body With Holding Plate for Screw and Crimp Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating bodies for electrical plug-in connectors are designed for either screw contacts or crimp contacts, requiring separate manufacturing and storage, which is costly and inefficient for ergonomic mass production.
Innovation Solution
An insulating body with a contact carrier and a holding plate that can accommodate both screw and crimp contacts, allowing for a modular system that uses a single holding plate design to stabilize both types of contacts, ensuring they can withstand plugging forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate insulating bodies are designed for screw contacts and crimp contacts, then each contact type can be securely fixed, but manufacturing and storage costs increase
Solution Approach 1:
The insulating body is designed with a universal contact carrier that can accommodate both screw contacts and crimp contacts through the same contact chambers. The holding plate with contact bushings provides a unified fixing mechanism that works for both contact types, eliminating the need for separate insulating body designs and reducing manufacturing complexity while maintaining secure fixation for each contact type
2Ease of manufacture
If a single insulating body design is used for both screw and crimp contacts, then manufacturing and storage are simplified, but sufficient holding force for both contact types cannot be achieved
Solution Approach 1:
The insulating body is segmented into functional components: contact chambers for receiving different contact types, a holding plate with contact bushings for secure fixation, and screw connection receptacles for lateral screw access. This segmentation allows the same insulating body structure to provide contact-type-specific fixation mechanisms, ensuring adequate holding force for both screw and crimp contacts while maintaining a unified design
3Reliability
If different insulating bodies are manufactured for different contact types, then each contact type receives optimized fixation, but component variety increases storage requirements
Solution Approach 1:
The insulating body employs universal contact chambers and a standardized holding plate design that can securely fix both screw contacts and crimp contacts. The contact bushings and screw connection receptacles are configured to accommodate different contact types without requiring different insulating body variants, thereby reducing component variety and storage requirements while maintaining fixation security

AI summary
In order to be able to equip a contact carrier (1) which is actually provided for receiving screw contacts, i.e. electrical plug contacts having screw connections, with crimp contacts (5) as well, a holding plate (3) can be latched on the contact carrier (1). Said holding plate (3) has a latching arm for each contact chamber of the contact carrier, said latching arm engaging in a screw connection receptacle of the contact chamber. As a result, the crimp contacts (5) inserted on the cable connection side can latch on the latching arm with their holding collar in the contact carrier (1).
