Introduction

SMM-119-02-F-S is a type of right angle-type vertical printed circuit board (PCB) electrical interconnect with female sockets. It is one of the rectangular connector families developed for applications where space is at a premium, and brings a variety of design advantages. Let us explore the application field and working principle of this rectangular connector.

Application Field

The SMM-119-02-F-S connector was designed with boards that have limited space in mind. It offers a low profile design that is ideal for projects or devices that require a small but reliable interconnection. This right-angle type vertical PCB connector is also suitable for many different types of electronic products including remote control, communication equipment, electronic toys, calculators, automotive electronics, audio and video equipment, medical instruments, and security systems. Furthermore, this type of connector is also compatible with a wide range of cables and PC boards.

Working Principle

This type of connector is mainly composed of two plastic injection molded mating halves and two contact sets. The two contact sets are inserted into two standard housing sizes and both contain a number of spring finger terminals. These terminals are inserted into the female sockets, from which they are held securely in place with a press-fit. The spring finger terminals are designed to establish a reliable electrical connection when mated with the male pin terminals. When the two connector halves are engaged, the pin terminals are pressed down by the force of the spring finger terminals. This pressing motion forces the pin terminals against the contact points of the female sockets and creates an electrical connection. The tension of the spring finger terminals ensures a tight and reliable connection between the two pieces of the connector.

Conclusion

The SMM-119-02-F-S is an economical right-angle type vertical PCB connector that was designed for applications where space is at a premium. The two parts of the connector are held securely together by the force of the spring finger terminals, ensuring a reliable electrical connection. This small yet reliable connector is suitable for a variety of applications, making it a versatile and adaptable choice.
