Simple SMD support

Technical Field

The utility model relates to a SMD encapsulates the field, particularly, relates to a simple and easy SMD support.

Background

SMDs are surface mount devices that are often used on surface mount light emitting diodes, SMD mounted LEDs, and the production of such mounted devices greatly increases the production efficiency of people and can be applied to a variety of different devices. When current SMD support encapsulates LED lamp pearl, structural stability is relatively poor, because of the structure is fixed moreover, can't change the service voltage, the electric current scope of lamp pearl, and the limitation is great. In the conventional patent, there is also a device for realizing serial-parallel switching by replacing the connection mode of the pin and the external circuit, but such a device is troublesome, and there is a risk of safety in frequently replacing the connection of the pin and the external circuit.
