Shielded Connector Assembly With Nested Light Guides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies with light guiding members occupy excessive space on circuit boards due to rear positioning of light guiding pipes, leading to interference between light sources.
Innovation Solution
A connector assembly featuring a shielding cage with apertures that allow light guiding pipes to pass through, positioning their rear segments inside the cage, reducing overall space occupation and minimizing light source interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If light guiding pipes are positioned outside the metal shell, then assembly is simplified, but the space occupied by the connector assembly on the board increases
Solution Approach 1:
The light guiding pipes are nested inside the metal shell structure, with rear segments positioned within the shielding cage. This nesting arrangement reduces the overall footprint of the connector assembly on the circuit board while maintaining the light guiding function, thereby resolving the contradiction between assembly simplicity and space occupation.
2Use of energy by moving object
If light guiding pipes are arranged along two sides without blocking, then light transmission is efficient, but light beams interfere with each other
Solution Approach 1:
The harmful effect of light beam interference is extracted and eliminated by positioning the light guiding pipes such that they are blocked by the metal shell structure. The rear segments are positioned inside the shielding cage, which prevents light beams from escaping and interfering with each other, while the front segments maintain efficient light transmission.
3Ease of manufacture
If rear segments of light guiding pipes are positioned outside the metal shell, then positioning is simplified, but light source interference occurs
Solution Approach 1:
The rear segments of the light guiding pipes are nested inside the metal shell's shielding cage, which simplifies positioning by providing a defined internal space while simultaneously preventing light source interference through the enclosing structure.

AI summary
A connector assembly is provided and includes a shielding cage, a receptacle connector and a light guiding member. The shielding cage has a plurality of walls, a receiving space defined together by the plurality of walls, a front end opening communicated to the receiving space and an aperture communicated to the receiving space. The receptacle connector is received in a rear segment of the receiving space of the shielding cage. The light guiding member has at least two light guiding pipes, each light guiding pipe has a first segment positioned to the front and a second segment positioned to the rear. The first segments of the two light guiding pipes are positioned outside the shielding cage and the second segments of the two light guiding pipes pass through the aperture and enter into the rear segment of the receiving space of the shielding cage.
