1. Summary

The 2.54mm pitch 3-pin U-shaped terminal female connector is a compact connection device that adopts the industry standard pitch. It is designed with a single row of 3 pins and a pin pitch of 2.54mm, suitable for standardized PCB layout and assembly requirements. It is commonly installed in the form of direct insertion (DIP) or 90 ° right angle, and can flexibly match different spatial layout scenarios. Its core feature is that the terminal adopts a U-shaped structure, which forms a stable connection with the male pin through a three sided wrapped contact. Compared with the Y-shaped terminal, the contact area is larger, which can significantly improve the connection reliability and anti vibration performance, and reduce the risk of poor contact.

2. Introduction

The 2.54mm spacing 3-pin U-shaped terminal female connector is a single row direct insertion device, with a standard spacing of 2.54mm to adapt to PCB layout. The core U-shaped terminal can wrap the male pin on three sides, improving connection reliability and vibration resistance. The shell is made of UL94V-0 grade flame-retardant plastic, which is resistant to high temperatures; The terminal is made of copper alloy material, with a surface plated with tin or gold, and a contact resistance of less than 20m Ω. Its single pin rated current is 1A-3A, rated voltage is 250V-500V AC, and it can stably transmit electrical signals. The working temperature is mostly from -25 ℃ to 105 ℃ (some up to -40 ℃ to 105 ℃), which meets environmental standards and is suitable for module interconnection and sensor connection in consumer electronics, industrial control and other fields.
