Contact Sleeve With Embedded Conductors For Camera Objectives
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera objective systems face challenges in efficiently and safely contacting and powering electrical consumers, such as heating devices, due to inflexibility of contact pins and insulation issues with metallic housing parts.
Innovation Solution
A contact sleeve with embedded electrical conductors made of non-conductive material, allowing for flexible and insulated electrical connection to camera objectives, including those with metallic housings, by using exposed contacting portions and a modular design that supports easy assembly and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact pins are used for electrical connection, then electrical contacting is achieved, but flexibility and alignment are impeded
Solution Approach 1:
The contact sleeve acts as an intermediary component between the contact pins and the camera objective. It provides a flexible mounting structure that allows the rigid contact pins to be positioned accurately while accommodating alignment variations through the sleeve's inherent flexibility and adjustment capabilities.
Solution Approach 2:
The electrical connection system is divided into separate functional components: the contact pins (for electrical contact), the contact sleeve (for flexibility and mounting), and the camera objective (for optical function). This segmentation allows each component to be optimized independently - the pins for reliable contact and the sleeve for alignment flexibility.
2Reliability
If contact pins are used for electrical connection, then electrical contacting is achieved, but insulation from metallic housing parts becomes problematic
Solution Approach 1:
The contact sleeve serves as an intermediary insulating barrier between the conductive contact pins and any metallic housing parts. This non-conductive intermediate structure eliminates direct electrical contact between the pins and metal housing, preventing short circuits while maintaining the electrical connection function.
Solution Approach 2:
The insulation function is extracted and embodied in the contact sleeve component. By separating the insulation requirement from the contact pin itself and placing it in the sleeve, the design resolves the conflict between electrical contact and insulation from metallic parts.
3Reliability
If conductor tracks are used for electrical connection, then electrical connection is achieved, but the structure becomes less flexible
Solution Approach 1:
The contact sleeve with contact pins provides a more flexible intermediary connection compared to rigid conductor tracks. The sleeve can be positioned and adjusted independently, allowing the electrical connection to adapt to variations in assembly tolerances and objective positions, thereby improving structural flexibility.

AI summary
A contact sleeve for a camera objective. The contact sleeve includes a sleeve-shaped base body made of an electrically non-conductive material, as well as at least one electrical conductor embedded in the material of the base body, preferably a contact pin, which has, at at least one end, an exposed contacting portion for electrically contacting an electrical consumer integrated in the camera objective. A camera objective having a contact sleeve and the use of the contact sleeve for contacting an electrical consumer of a camera objective, are also described.
