Low Profile Plug Connector Assembly with Integrated Transverse Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector designs with paddle cards increase the height and length of plug connectors, necessitating a lower profile configuration for more compact applications.
Innovation Solution
A plug connector design featuring an insulative body with alternately arranged differential-pair and grounding contacts, where all contacts and a transverse bar are stamped from the same sheet metal, with differential-pair contacts being disconnected from the transverse bar after formation, and a receptacle connector with longitudinal walls and passageways for mounting on a printed circuit board, allowing for a more compact and efficient connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a paddle card is used to connect the plug connector to the receptacle connector, then the plug connector can be linked with wires, but the length and height of the plug connector increase
Solution Approach 1:
The patent removes the paddle card component from the plug connector assembly. The plug connector is designed to directly mate with the receptacle connector without requiring a paddle card intermediary, thereby eliminating the height increase that would result from including a paddle card.
Solution Approach 2:
The plug connector integrates the contact elements and insulative body into a unified structure that directly interfaces with the receptacle connector. This merging eliminates the need for separate paddle card components, reducing overall assembly dimensions while maintaining electrical connectivity.
2Ease of manufacture
If a paddle card is used to connect the plug connector to the receptacle connector, then the plug connector can be linked with wires, but the height of the plug connector increases
Solution Approach 1:
The patent extracts and eliminates the paddle card from the plug connector design. By removing this height-increasing component, the plug connector achieves a lower profile configuration that is more suitable for compact applications while still maintaining the ability to connect wires through alternative structural arrangements.
Solution Approach 2:
The patent redesigns the plug connector to achieve wire connectivity without increasing height in the vertical dimension. The connector utilizes horizontal arrangement and alternative connection paths that maintain electrical functionality while optimizing the vertical profile for compact applications.

AI summary
A plug connector adapted for connecting corresponding wires includes an insulative body integrally formed with two rows of plug contacts in a lateral direction and a transverse bar. The plug contacts are categorized with differential-pair contacts and grounding contacts alternately arranged with each other in a longitudinal direction. The transverse bar extends along the longitudinal direction perpendicular to the lateral direction and is unitarily linked to rear ends of all the grounding contacts of each row of plug contacts while being isolated from the differential-pair contacts. All the contacts and the transverse bar are stamped from a same sheet metal initially, and the differential-pair contacts are successively disconnected from the transverse bar after the plug contacts are integrally formed with the insulative body.
