Introduction

Rectangular connectors, also known as headers, male pins, and card edge connectors, are one of the most widely used types of electrical connectors, used in a variety of electronic and electrical systems. The 91687-320LF application field and working principle is an important part of this family of connectors.

Application Field

The 91687-320LF is a 19-pin low profile card edge connector made from UL94V-0 rated high temperature thermoplastic. It is suitable for use in a variety of applications, including those in industrial, automotive, telecommunications, consumer, and medical equipment. The 91687-320LF features a polarized double locking latch that locks the mating connector securely and prevents accidental disconnection due to jostling or shocks. Similarly, the 91687-320LF\'s low profile design allows for a slim profile, making it suitable for use in portable devices and applications where space is at a premium. The 91687-320LF is also equipped with a rugged design, making it suitable for use in high temperature and/or vibration-prone applications.The 91687-320LF has a maximum current rating of 5 amp with a voltage rating of 250V. It is UL approved and RoHS compliant, and is available in multiple colors, including black, blue, and green.

Working Principle

The 91687-320LF incorporates a double locking latch design that ensures a firm connection between the mating connectors. When the connectors are mated, the latches latch together, ensuring a secure and positive connection. The positive connection is further enhanced by the fact that the 91687-320LF has a polarization slot which ensures that the connectors are mated in the right orientation. The 91687-320LF is also designed with two integral mounting holes, which enables the connector to be mounted securely and quickly to a variety of surfaces. The connectors also feature a unique spring-loaded lead mechanism that provides a consistent pressure on the mating surface, and eliminates the need for pin and socket contact forces.

Conclusion

In conclusion, the 91687-320LF is a versatile and reliable rectangular connector suitable for a wide range of applications. Its low profile design, double locking latch, and integral mounting holes are designed to provide a secure and positive connection. The 91687-320LF also features a spring-loaded lead mechanism that ensures a consistent pressure on the mating surface. The 91687-320LF is UL approved and RoHS compliant, and is available in three colors.
