8+2 XLR PCB Female Connector Layout for Horizontal Board Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors, such as XLR connectors of type 8 + 2, are limited in their application due to the vertical arrangement of connections, which prevents them from being used with horizontal printed circuit boards, and existing solutions for connectors with multiple data or energy channels are not easily adaptable for horizontal connections.
Innovation Solution
A built-in electrical connector design featuring a housing with angled contact sections that connect to a circuit board in a common plane parallel to the housing's longitudinal axis, allowing for both data and energy transmission with separate contact diameters and a secure mounting structure, enabling connection to both vertical and horizontal circuit boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If XLR connectors are designed with vertical connection arrangement, then connection to vertical circuit boards is achieved, but connection to horizontal printed circuit boards is prevented
Solution Approach 1:
The patent applies dimensionality change by transitioning from a vertical connection arrangement to a horizontal connection arrangement. The contact elements are configured to extend horizontally from the housing rather than vertically, enabling connection to horizontal circuit boards while maintaining the same connector body structure. This dimensional transformation resolves the contradiction by expanding adaptability without increasing device complexity.
2Quantity of substance
If multiple data and power channels are integrated in a single connector, then channel capacity is improved, but connector size and complexity increase
Solution Approach 1:
The patent merges multiple functions into a single integrated connector housing that accommodates both data transmission contacts and power transmission contacts. The contact carrier holds multiple contact elements (including ground contacts, data contacts, and power contacts) in a unified structure, eliminating the need for separate connectors for different signal types. This merging approach increases channel capacity while controlling the overall connector volume through efficient spatial arrangement.
Solution Approach 2:
The connector housing is designed as a universal structure that can accommodate various types of contacts (ground, data, and power) within a single body. The contact carrier system provides a multi-functional platform that supports different contact configurations and arrangements, enabling the same connector design to handle multiple data and power channels without requiring separate specialized connectors for each function.
3Ease of operation
If contact elements are arranged in a staggered position with deflection points, then sufficient space for contact-free arrangement is achieved, but manufacturing precision requirements increase
Solution Approach 1:
The patent segments the contact elements into distinct sections with defined deflection points, allowing each contact to be independently positioned and arranged in a staggered configuration. This segmentation enables sufficient spacing between contacts for easy assembly and installation while maintaining precise geometric relationships through the modular contact carrier design. Each contact element can be individually adjusted or replaced without affecting the entire contact array.
