Rectangular connectors are devices used to join wires to a circuit board or power source. Also known as headers and male pins, the 68457-408HLF is one of the most commonly used models of rectangular connectors and is often employed in the automotive industry. In this article, we will discuss the application field and working principle behind the 68457-408HLF.

68457-408HLF Application Field

The 68457-408HLF is a type of positive lock rectangular connector commonly used in the automotive industry. The connector is designed for use with high voltage applications, and it is UL recognized for UL 746 specified Service Equipment Marking. This connector is typically used for applications requiring high strength, high visibility, and corrosion resistance in harsh environments.Recently, the 68457-408HLF has found more uses in other industries such as medical and aerospace. Its small size, high impact resistance, and wide temperature range allow it to be used in a variety of applications. It is increasingly being adopted for applications requiring connections in adverse conditions, and its positive lock technology ensures a secure connection with minimal risk of loosening or accidental disconnection.

68457-408HLF Working Principle

The 68457-408HLF utilizes a “positive lock” mechanism to achieve a secure and reliable connection. This mechanism is based on a small locking pin that is connected to the male connector and operates by engaging in the corresponding female connector during mating.Once engaged, the pin exhibits a positive locking force that overrides the mating force, preventing the connection from being accidentally disconnected or loosened under vibration or shock. This locking force is further increased as the 65 degree beveled edges of the mating pins are compressed together. The compression of the beveled edges ensures a vibration resistant connection with maximum contact pressure, minimizing the risk of accidental disconnection.

Conclusion

The 68457-408HLF is a positive lock rectangular connector, greatly suitable for use in a variety of high voltage automotive, medical, and aerospace applications. Its positive lock mechanism includes the use of a locking pin and 65 degree beveled edges for increased contact pressure, allowing for a vibration resistant and secure connection.
