Electrical Connector with Oblique Shielding Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors for printed circuit boards are not adequately supported and do not comply with obliquely extending retaining sections, making them unfit for device casings with standard insertion openings.
Innovation Solution
An electrical connector design featuring a contact module with an insulative housing, metallic shells, and a metallic shielding plate with oblique sections, along with Z-shaped fixing columns, which provides proper support and alignment with obliquely extending contacts, ensuring compatibility with device casings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a sink type connector is used for low profile arrangement, then the connector can be mounted in a notch of the printed circuit board, but it does not fit with device casings having upper or standard level insertion openings
Solution Approach 1:
The patent introduces an oblique dimension to the connector structure, with insulators and contacts extending at an angle rather than purely vertically or horizontally. This oblique configuration allows the connector to adapt to both low-profile PCB mounting and standard-level device casing openings, effectively resolving the dimensional conflict between profile height and adaptability.
2Reliability
If conventional connectors are mounted on printed circuit boards, then they can provide electrical connections, but they lack proper support around the shell and do not comply with obliquely extending retaining sections
Solution Approach 1:
The patent employs asymmetric structural design where the insulators and contacts are configured with oblique extensions that match the asymmetric retaining sections of the device casing. This asymmetric configuration provides proper structural support around the shell while maintaining reliable electrical connections, addressing both stability and reliability requirements.

AI summary
An electrical connector including a contact module having an insulative housing with a plurality of contacts disposed therein and enclosed within a first metallic shell, and a second metallic shell attached to the first shell and located between the first shell and the printed circuit board so as to allow the raised type mating cavity which is formed by the first shell. The contact module includes a metallic shielding plate with an oblique section. A pair of Z-shaped fixing columns are located by two sides of the oblique section.
