Patent: Pin Socket for Electrical Connector with Enhanced Durability
A patent (CN224288715U) filed in May 2026 describes a pin socket for an electrical connector featuring a multi-layer protective structure and a quick-locking mechanism to prevent loosening .
Key Technical Innovations:
Component | Function |
|---|---|
Wear-resistant layer | Supports electromagnetic shielding layer; resists wear from friction |
Electromagnetic shielding layer | Blocks electromagnetic interference |
Insulation layer | Provides electrical isolation |
Base layer | Foundation structure for the socket |
First spring + sliding block | Enables quick connection and anti-loosening mechanism |
Quick-Connection Mechanism:
The first spring is compressed by squeezing the sliding block, and then the sliding plate is rotated by rotating the support rod. Subsequently, the connecting rod rotates with the sliding plate, achieving quick connection and prevention of loosening. This provides strong fixing force after the needle seat is inserted to prevent connection loosening due to external pulling or vibration .
Benefits:
Strengthens internal structure of the pin socket
Improves resistance to external forces
Prevents deformation or damage during insertion/removal
Effective against vibration and impact during equipment operation
