1551768-1

Barrel - Power Connectors

1551768-1 is a barrel power connector used to provide the connection of power. It is fully sealed by waterproof cover which greatly extends the service life and ensures more safe and reliable operation environment. The connector has a variety of wiring options for providing different power supply voltage. The 1551768-1 is a suitable choice for applying in many fields, such as automotive, railway, renewable energy, aviation, marine, microwave communication, shipbuilding, industrial control, etc.

Application Field

1551768-1 is a low voltage terminal commonly used in the power supply system. It can be divided into two categories according to different products:first is low-current type, suitable for low voltage power supply such as USB,digital photo frame, dental equipment, instrumentation, heart rate monitor, medical device, GPS device, and so on; second is high-current type, suitable for large current power, such as electric vehicle, electric aircraft, industrial control, new energy batteries, and so on. Low voltage type can meet various requirements in current control, power supply or signal transmission. While the high voltage type covers up to 400A current, allowing higher load capacity.

Working Principle

1551768-1 is made up of an inserted contact, a metal post and a cover. When applying, the inserted contact is inserted into the socket and the metal post is connected with the terminals of the clip. When tightening the screws, the metal post is pulled together with the socket, ensuring the perfect closed mating condition. Then the cover is installed. The cover can prevent water or dust from entering the connector and extends the service life. At the same time, it also prevents inadvertent connection of any two conductive objects and ensures safe connection.

The inserted contact of 1551768-1 adopts screw terminal type. The loose wiring is in the socket, while the wires connect the inserted contacts and the terminals of the clips. The connection is reliable and vibration resistant. The design of shell cover ensures the perfect waterproof and dust-proof mating condition. And the materials of shell cover and its contact mouth can be customized to meet more harsh requirements.

Conclusion

1551768-1 is a kind of barrel power connectors. It has a variety of wiring options for providing different power supply voltage. It can meet the needs of low voltage power supply for USB, instrumentation, medical device and so on. The high voltage type can be up to 400A current, as well as providing higher load capacity. This connector takes screw terminal type, its connection performs reliable and vibration resistant. The waterproof and dust-proof design of shell cover ensures the more safe and reliable operation environment, and also extend its service life.
