Oblique Electrical Connector for PCB Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors designed for printed circuit boards often lack proper support and alignment with device casings, particularly when the connector's contacts extend obliquely, leading to compatibility issues with standard insertion openings.
Innovation Solution
An electrical connector design featuring a contact module with an insulative housing, inner and outer metallic shells, and a metallic shielding plate with oblique sections, providing a raised mating cavity and secure assembly with oblique abutment portions to align with the printed circuit board and device casing, ensuring proper support and compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the electrical connector is designed as a sink type connector located in a notch of the printed circuit board, then the connector achieves a low profile arrangement, but the connector becomes incompatible with device casings having upper or standard level insertion openings
Solution Approach 1:
The patent introduces an oblique dimension to the connector structure, transitioning from a conventional horizontal/vertical arrangement to a three-dimensional oblique configuration. The contacts extend obliquely from the printed circuit board, and the insulators are correspondingly shaped to accommodate this oblique orientation, enabling compatibility with both low profile and standard level device casings
2Adaptability or versatility
If the contacts extend obliquely to comply with device casing requirements, then the connector achieves compatibility with oblique insertion openings, but the connector lacks proper support and alignment with standard printed circuit board mounting structures
Solution Approach 1:
The patent employs asymmetric design in the insulator structures, with the first and second insulators having different configurations tailored to their respective positions. The insulators feature oblique sections that match the oblique contacts, while simultaneously providing stable mounting surfaces for the printed circuit board, achieving both oblique compatibility and structural stability through asymmetric geometry
Solution Approach 2:
The patent implements a nested structure where the first and second insulators are positioned to enclose and support the oblique contacts, with the insulative housing containing all components. This nested arrangement provides multiple levels of support and alignment, ensuring stable PCB mounting while maintaining oblique contact extension for device casing compatibility

AI summary
An electrical connector adapted for mounting to an upper surface of the printed circuit board, includes a contact module having an insulative housing with a plurality of contacts disposed therein and enclosed within an inner metallic shell, and an outer metallic shell attached to the inner shell and located between the inner shell and the printed circuit board so as to allow the raised type mating cavity which is formed by the inner shell. The contact module includes a metallic shielding plate with an oblique section. The housing forms an oblique section on the rear side to comply with the oblique section of the shielding plate wherein a receiving space is formed above a rear side of the connector and in alignment with a mating cavity of the inner shell in the front-to-back direction.
