Multi-Angle Electrical Connector Housing With Segmented Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors have limited flexibility and utilization rate due to their design, which allows connection from only a single angle, making them less suitable for mass production and market demands for high-performance, low-cost, and lightweight components.
Innovation Solution
The electrical connector design includes a housing with multiple insertion openings and portions, allowing for electrical connection from at least two angles (e.g., 90 degrees and 180 degrees), thereby enhancing flexibility and utilization rate.

If a sheet-type conductive unit with snap spring wrapping reed is used, then the connector size is reduced, but the conductive unit can only be matched from a single angle, reducing utilization rate
Solution Approach 1:
The conductive unit is divided into multiple independent contact pieces (first contact piece, second contact piece, third contact piece, fourth contact piece) that can independently deform and make contact. This segmentation allows each contact piece to engage with corresponding electrical connecting devices from different directions, enabling multi-angle matching while maintaining compact size.
Solution Approach 2:
The contact pieces are designed with elastic properties allowing them to dynamically deform during insertion from different angles. The snap spring provides dynamic force to push the contact pieces outward, enabling them to adaptively engage with electrical connecting devices inserted from various directions (front, rear, left, right sides).
2Power
If a cylindrical electrical connecting device jack-type conductive unit is used, then current-carrying capacity is limited and cost is high, but structural simplicity is reduced
Solution Approach 1:
Instead of using a traditional cylindrical jack-type conductive unit, the patent employs a sheet-type conductive unit with multiple contact pieces that copies the essential function of electrical connection. This sheet-type design can be mass-produced through stamping and forming processes, significantly reducing manufacturing complexity and cost while maintaining adequate current-carrying capacity through multiple parallel contact paths.
Solution Approach 2:
Multiple contact pieces are merged into a single integrated sheet-type conductive unit structure. This combining approach allows the conductive unit to provide multiple electrical connection paths simultaneously, increasing current-carrying capacity while simplifying the overall structure and production process compared to traditional cylindrical designs.
3Ease of manufacture
If the conductive unit is fixed after snap spring and reed are assembled, then assembly is simplified, but the utilization rate for mass production is reduced
Solution Approach 1:
The conductive unit is designed with universal multi-functionality, capable of matching electrical connecting devices inserted from multiple directions (front, rear, left, right sides). The symmetrical arrangement of contact pieces and the elastic deformation capability enable the same conductive unit structure to serve multiple insertion scenarios, significantly increasing utilization rate for mass production while maintaining assembly simplicity.
