Detailed Description

In order to make the technical field of the present invention better understand, the present invention is further described in detail with reference to the accompanying drawings and embodiments.

As shown in fig. 1-4, an embodiment of the present invention provides an ultra-thin D2S converter with a built-in LED driver, which includes a housing 1 and a PCB 2 disposed in the housing, wherein a large capacitor 3 and a magnetic ring inductor 4 are disposed on a back surface of the PCB 2; in order to place the large capacitor 3 and the magnetic ring inductor 4, a first accommodating portion 101 and a second accommodating portion 102 are provided in the housing 1, and the first accommodating portion 101 and the second accommodating portion 102 are integrally formed with the housing 1.

The PCB 2 is a PCB with the thickness of 1 mm.

The first accommodating portion 101 is internally provided with an anode conductive column 5, and the magnetic ring inductor 4 is sleeved on the anode conductive column 5 and is positioned in the first accommodating portion 101; the large capacitor is located in the second receiving portion 102.

Because the magnetic ring inductor 4 is circular, the first accommodating part 101 is circular and corresponds to the magnetic ring inductor 4 in shape, and the positive conductive column 5 is arranged along the axial direction of the first accommodating part 101; when the housing 1 is designed and processed, the first receiving portion 101 and the second receiving portion 102 protrude from the back surface of the housing 1, and the thickness of the first receiving portion 101 protruding from the back surface of the housing 1 is greater than the thickness of the second receiving portion 102 protruding from the back surface of the housing 1. The positive conductive column 5 is an element that must be arranged, and therefore, the first accommodating portion must also be arranged so as to install the positive conductive column 5, and during assembly, the positive conductive column 5 and the magnetic ring inductor 4 are integrated together, and no additional space is required to be arranged for installing the magnetic ring inductor 4, and meanwhile, the thickness of the second accommodating portion 102 protruding out of the back surface of the housing 1 is smaller than the thickness of the first accommodating portion 101 protruding out of the back surface of the housing 1, so that the thickness of the housing 1 cannot be additionally increased by arranging the first accommodating portion 101.
