Abstract

This utility model discloses a flexible pin connector, including a plug housing, a plug insulator inside the plug housing, a pin mounting hole in the plug insulator, and a flexible pin installed in the pin mounting hole. The flexible pin includes a central body portion, a front spring portion extending from the front end of the central body portion, and a rear crimp portion connected to the rear end of the central body portion. The rear crimp portion is connected to a solder pin or cable. The central body portion and the pin mounting hole are connected by an interference fit. This utility model's flexible pin connector has significant advantages. The interference fit between the flexible pin and the rigid socket enables miniaturization. It features low insertion and extraction force, reliable contact, and a double spring structure that ensures high mechanical life and durability. It exhibits stable performance under high-speed vibration and impact, making it widely applicable in various fields. The one-piece stamped flexible pin avoids pin shrinkage, resulting in consistent product quality, high reliability, simple processing, and low cost, making it highly competitive in the market.
