D-Sub connectors are the most widely used and most popular type of standard connector in existence. The letters “D” represent the shape of the connector when viewed from above and refer to the two large metal “D-shaped” housings. These housings are connected by either an integral cable or a soldered connection. The large size of the connector often requires the use of a backshell and a hood to improve strain relief and to greatly increase the number of mating cycles.

Application Field and Working Principle of 1727040199

1727040199 is a type of D-sub backshells and hoods. It is designed to fit most standard D-sub connectors with an OD of 17.2-21.2, such as DB9, DB15, DB25, and HD15. The 1727040199 is UL recognized and RoHS compliant, providing reliable and effective service for commercial and industrial applications. It is composed of two halves consisting of a metal backshell and a plastic hood.

The backshell is constructed from a zinc-plated steel alloy and is designed to provide superior shielding between the conductors inside the connector and the external environment. The backshell is connected to the connector using four mounting screws, allowing quick and easy installation and removal. In addition, the backshell effectively protects the D-sub connectors from environmental hazards such as water, dust, debris, and electrical noise.

The hood is injection molded from a high-temperature polyurethane plastic, and is designed to provide the greatest amount of protection and durability. The hood firmly anchors itself to the backshell through the use of locking tabs and is designed to snap into place, ensuring a secure connection. The hood provides additional safety by preventing the risk of electric shock or fire due to stray currents or stray sparks.

1727040199 backshells and hoods are an effective solution for a variety of connector applications. They provide superior electrical shielding between the connected conductors and the external environment, which is critical in preventing potential electrical hazards. In addition, the backshell and hood provide additional protection from outside sources such as water, dust, debris, and electrical noise. Lastly, the simple installation and removal of the backshell and hood further increases their usefulness and overall versatility.
