High-Density Rotating Connector with Clipped Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors have a limited number of contacts, which necessitates multiple connectors to achieve electrical connection, leading to increased space occupation and operational inconvenience, particularly in medical instruments that require enhanced functionality.
Innovation Solution
A connecting device with high-density contacts is designed, comprising a plug connector with a post portion and a socket connector with a barrel portion, where the first terminals are exposed on the post and the second terminals are arranged in a multi-segment bend configuration, allowing for high-density and reliable signal contacts within a limited volume by rotating and clipping the first contacting portions between the second contacting portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple connectors are used to increase the number of contacts, then the electrical connection capability is improved, but the space occupation increases
Solution Approach 1:
The patent combines multiple connectors into a single integrated connector structure. The first connector and second connector are merged into one unified component with a common insulating housing, allowing multiple contact groups to coexist in a compact arrangement. This merging approach increases the number of contacts while minimizing the overall space occupation by eliminating redundant structural elements between separate connectors.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by disposing contact groups in multiple layers and directions within the insulating housing. The contacts are arranged not only linearly but also in radial and axial dimensions, maximizing the contact density within the available volume. This multi-dimensional positioning allows high contact density without proportionally increasing the connector's external dimensions.
2Quantity of substance
If the number of contacts is increased, then the signal transmission capability is improved, but the contacting force per contact is reduced
Solution Approach 1:
The patent divides the contacts into multiple independent contact groups, where each group contains multiple contacts that work together. This segmentation allows the total contacting force to be distributed across multiple contacts within each group, ensuring that individual contacts maintain sufficient force while the overall system achieves high contact density. Each contact group can be independently optimized for force distribution.
Solution Approach 2:
The patent incorporates elastic elements and flexible contact structures that dynamically adjust the contacting force. The contacts are designed with elastic properties that allow them to automatically compensate for variations in insertion force, ensuring consistent contacting force across all contacts regardless of manufacturing tolerances or assembly variations. This dynamic adjustment maintains reliable electrical connection across all contacts.
3Ease of manufacture
If conventional connector design is used, then the manufacturing simplicity is maintained, but the contact density is limited
Solution Approach 1:
The patent designs a universal connector structure where a single insulating housing can accommodate multiple contact groups with different configurations. The standardized housing design allows for flexible arrangement of contacts without requiring custom manufacturing for each contact pattern. This universal approach enables high contact density while maintaining manufacturing simplicity through modular assembly and standardized components.

AI summary
A connecting device with high-density contacts includes a plug connector and a socket connector. The plug connector has a first insulated housing and a plurality of first terminals. The first insulated housing has a post portion. The first terminals are disposed on the post portion. The socket connector has a second insulated housing and a plurality of second terminals. The second insulated housing has a barrel portion formed with an accommodating space. The second terminals are disposed on the barrel portion. The post portion of the plug connector is inserted into the accommodating space. The plug connector and the socket connector are rotatable relative to each other. First contacting portions of the first terminals are clipped between two contacting portions of the second terminal, so that the first terminals are conductively contacted with the second terminals. Thus, the present disclosure provides signal contacts with high-density and high-reliability.
