Electrical Connector Nested Secondary Piece for High-Frequency Signal Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors for CPUs face challenges in miniaturization due to the additional space required by side upstanding bars for enhanced high-frequency signal transmission, which hinder the compact design needed for modern electronics.
Innovation Solution
The design incorporates a primary piece with deflectable contacting arms and a secondary piece that is encircled by the primary piece, allowing for horizontal alignment and assembly within the same passageway, enabling efficient high-frequency transmission without increasing the connector's footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a side upstanding bar is added to create a secondary transmission path, then high frequency signal transmission is enhanced, but the connector occupies additional space in the passageway
Solution Approach 1:
The secondary piece is positioned inside the passageway space already occupied by the primary piece, specifically within the region bounded by the contacting arms and abutment sections. This nesting arrangement allows the secondary transmission path to coexist with the primary transmission path without requiring additional external space, thereby resolving the contradiction between signal transmission quality and compactness
2Ease of manufacture
If the secondary piece is positioned outside the primary piece, then assembly is simplified, but the connector footprint increases
Solution Approach 1:
The secondary piece is nested within the spatial envelope of the primary piece, specifically positioned between the contacting arms and abutment sections of the primary piece. This internal positioning maintains a compact connector footprint while still providing the necessary secondary transmission path functionality
3Volume of moving object
If the secondary piece is encircled by the primary piece, then space is saved, but assembly complexity increases
Solution Approach 1:
The contact unit is divided into distinct segments: the primary piece with contacting arms, the secondary piece with additional contacting arms, and the insulative housing with passageways. This segmentation allows each component to be manufactured and positioned independently, then assembled in a systematic manner that reduces overall assembly complexity despite the nested configuration

Function Achieved in This Case
This configuration achieves superior impedance matching and reduced signal loss while maintaining a compact form factor, supporting the miniaturization trend by utilizing a secondary piece that is effectively encircled by the primary piece, enhancing electrical connectivity without occupying additional space.
Implementation Method 1
The upper part includes an upper retaining section and a resilient upper contacting arm extending upwardly above the upper surface of the housing with an upper contacting section and an upper abutment section at a free end thereof. The lower part includes a lower retaining section and a resilient lower contacting arm extending downwardly below the lower surface of the housing with a lower contacting section and a lower abutment section at a free end thereof.
Implementation Method 2
a secondary piece providing a side upstanding bar for respectively linking the two contacting arms to create a secondary transmission path other than the primary transmission path performed by the primary piece so as to enhance the high frequency signal transmission

AI summary
A contact unit for use within a connector includes a primary piece essentially composed of an upper part and a lower part coupled with each other. The upper part includes an upper retaining section and a resilient upper contacting arm with an upper contacting section and an upper abutment section at a free end thereof. The lower part includes a lower retaining section and a resilient lower contacting arm extending downwardly with a lower contacting section and a lower abutment section at a free end thereof. A secondary piece is spaced from and opposite to the primary piece in a horizontal direction of the contacting arm, and includes an upper abutment region adapted to be abutted against by the upper abutment section of the upper contacting arm, and a lower abutment region adapted to be abutted against by the lower abutment section of the lower contacting arm.
