PCB Plug Device Pre-Adjusting Alignment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handling and positioning sensitive contact elements on a printed circuit board for direct plug devices can be challenging, leading to potential misalignment and damage.
Innovation Solution
A direct plug device with a plug element and receptacle featuring pre-adjusting structures that align with corresponding structures on the printed circuit board, allowing for intuitive and robust electrical and mechanical connection without the need for a socket, using a locking mechanism that ensures secure attachment with minimal user effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact elements are made sensitive and pluggable for direct connection, then electrical connectivity is improved, but handling and positioning becomes difficult
Solution Approach 1:
The pre-adjusting structure is positioned and connected to the printed circuit board before the contact elements are inserted. This preliminary positioning action establishes the correct alignment and location, making the subsequent insertion of sensitive contact elements easier and more reliable without requiring precise manual positioning by the user.
2Manufacturing precision
If pre-adjusting structures are added for alignment, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The pre-adjusting structure is integrated as part of the plug element assembly rather than being a separate component. The pre-adjusting structure is formed integrally with the plug element housing, combining multiple functions (alignment, positioning, and structural support) into a single unified component, thereby achieving precise positioning without proportionally increasing overall device complexity.

AI summary
A direct plug device for directly plugging into a printed circuit board, the direct plug device comprising a plug element that comprises an accommodating housing and at least one pluggable, in particular spring-like, contact element accommodated at it; and a plug element receptacle which is designed to at least partially accommodate the plug element, which comprises a locking device and which can be moved relative to the plug element between a contact element-remote state and a contact element-proximal state; wherein the plug element comprises at least one pre-adjusting structure which is to be arranged at the side of the printed circuit board and which, when the plug element is placed onto the printed circuit board, can be connected to at least one corresponding pre-adjusting structure of the printed circuit board in such a way that, in the connected state, the at least one contact element is aligned with at least one correspondingly designed contact element opening of the printed circuit board; andwherein the plug element receptacle can be displaced relative to the plug element, which is placed on the circuit board in a pre-adjusted manner, from the contact element-remote state to the contact element-proximal state in such a way that thereby the locking device and the pre-adjusting structure of the plug element are commonly locked to the pre-adjusting structure of the printed circuit board.
