Shunts and jumpers are two commonly used terms in electrical and electronics circuits which can allow current to jump to a different path or bypassing the components. DF11-8DP-SP1(05) is an example of such device.

DF11-8DP-SP1(05) is a shunting and jumpering device, mainly used in automotive applications. It has a 8-pin design and can handle up to 18A current. Moreover, it is capable of printed circuit board (PCB) connection and longitudinal displacement connection. The body material is made of PBT polyester and it is resistant to chemicals and oil. Furthermore, it is mounted on flat surface or cylindrical surface according to requirements.

The typical application fields of DF11-8DP-SP1(05) include vehicle, machinery, and electrical appliances. Specifically, it can be used for signal, transmission, interface, display, motor drive, transformer and etc. In the design process, it can provide reliable and strong connection for printed circuit line as well as avoiding contact failure caused by vibration or shock. The mileage of the device is also significantly improved due to the good vibration resistance property.

The working principle of DF11-8DP-SP1(05) is explained as follows: It has two metal pieces and sandwiched in between is an insulator. When connecting, the metal pieces are pressed hard to make sure the connection is firm. The combination of pressure and friction i.e. the high contact force established between the two metal pieces generates heat due to internal contact resistance. Consequently, the insulator will thermally melt and force the connection more firmly and solidify. This process of increasing contact pressure until the melting point of the insulator is reached is known as “cold welding.”

At this point, DF11-8DP-SP1(05) can effectively transfer electrical current from one terminal to another. Moreover, this type of connection is highly reliable due to the cold welding process. In addition, the mechanical properties of the device remain stable even at extreme temperatures and can handle high current values.

In conclusion, DF11-8DP-SP1(05) is an example of a reliable shunt and jumper. Its compact design and high current capacity makes it a suitable candidate for automotive applications. The cold welding process ensures strong connection between the two metal pieces while maintaining consistent mechanical properties under extreme temperatures. Thus, it can serve to provide reliable and consistent connection between the PCB and other components.
