Plug Connection Device Recess for Component Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug connection devices for printed circuit boards face challenges in achieving high functional density due to space constraints caused by connector strips and plugs, limiting the arrangement of components and increasing the risk of collisions and external influences on mating contacts.
Innovation Solution
The design incorporates a plug connection device with movable contact elements and a recess on the substrate to accommodate components, allowing for closer placement of mating contacts and components, while the plug overlaps the substrate to ensure secure hold and protection from external influences, with insulation recesses and struts to prevent short circuits and moisture interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector strip or plug is used for electrical contacting, then reliable electrical connection is achieved, but the available space for components on the substrate is reduced
Solution Approach 1:
The plug is designed to overlap the substrate in the vertical dimension rather than occupying lateral space. The recess in the plug housing allows components to be positioned on the substrate surface in areas that would otherwise be occupied by the plug body, effectively utilizing the vertical stacking dimension to resolve the space conflict.
Solution Approach 2:
The component is nested within the recess of the plug housing, allowing the component to be positioned in the area where the plug overlaps the substrate. This nesting arrangement enables both the electrical connection function and component placement to coexist in the same lateral footprint.
2Loss of time
If components are placed close to mating contacts to reduce signal propagation time, then signal speed is improved, but the risk of collision and external influences on mating contacts increases
Solution Approach 1:
The plug housing acts as a protective shell that encloses the mating contacts and overlapping substrate area. The housing provides physical protection against external influences such as moisture, dust, and mechanical damage, while allowing the component to be positioned close to the mating contacts through the recess.
Solution Approach 2:
The plug housing is designed with insulation recesses and protective structures that prevent harmful effects before they can occur. The housing creates a protective barrier around the mating contacts and overlapping area, preemptively shielding them from external influences while maintaining electrical functionality.
3Stability of the object's composition
If the plug overlaps the substrate to ensure secure hold, then mechanical stability is improved, but the space for component arrangement is further limited
Solution Approach 1:
The overlap design utilizes the vertical dimension to achieve mechanical stability through friction and engagement features between the plug and substrate edges, rather than requiring extensive lateral coverage. This allows components to be arranged in the lateral space that would otherwise be occupied by the plug body.
Solution Approach 2:
The plug housing is segmented with a recess that creates distinct functional zones: the overlapping portion provides mechanical stability through edge engagement, while the recessed portion accommodates components on the substrate. This segmentation allows both stability and component placement to coexist.
