Description

power conversion module

technical field

The present invention relates to a power conversion module, and in particular to a power conversion module for converting commercial power into direct current power for a flat panel display.

Background technique

The power board module is a kind of power conversion module, which has the advantages of small size and low cost. In today's flat-panel displays, such a power conversion module for converting mains power into DC power is mostly used as a power supply device for converting the power supply form.

Referring to FIG. 1, it is a schematic view showing a conventional power circuit board module. A traditional power circuit board module 10 mainly includes a power circuit board 101 , a socket 103 and a protective shell 105 .

The socket 103 is welded on the power circuit board 101 . The protective shell 105 has a hole 1050 , and the hole 1050 penetrates through the protective shell 105 . The power circuit board 101 is disposed in the casing 105 , and the socket 103 can be exposed through the hole 1050 .

The purpose of the protective shell 105 is to shield the low-frequency electric field radiation generated by the power circuit board 101 . On the other hand, in addition to the power circuit board 101 , other electronic components such as logic circuit boards are also arranged in the casing 105 . Through the protective shell 105 fixed in the flat-panel display, these electronic components can be arranged at proper positions in the flat-panel display.

As shown in FIG. 1 , due to electrical constraints and structural design, the size of the protective case 105 in the direction X1 is approximately equivalent to the size of the power circuit board 101 in the direction X1 .

In the process of combining the power circuit board 101 and the protective case 105, first put the power circuit board 101 into the protective case 105, then slightly tilt the power circuit board 101, so that the socket 103, connectors 107a, 107b enter the holes 1050, 107b, respectively. After 1052a, 1052b. Next, make the power circuit board 101 horizontal, so as to lock the power circuit board 101 in the casing 105 .

In order to expose the socket 103 and the connectors 107a and 107b respectively through the holes 1050, 1052a and 1052b, the holes 1050, 1052a and 1052b are designed to be larger than the socket 103 and the connectors 107a and 107b. Taking the socket 103 as an example, the reason for making the hole 1050 larger is to enable the socket 103 which is in an inclined state with the power circuit board 101 to be smoothly inserted into the hole 1050 . However, when the power circuit board 101 is fixed to the protective shell 105 in a horizontal state, a gap 1054 will be left between the outer side of the socket 103 and the hole 1050 .

Referring to Fig. 2, it is a schematic diagram showing the combination of the power supply circuit board and the protective shell. As shown in FIG. 2 , it is a cross-sectional view of the socket 103 and the protective case 105 after the power circuit board 101 and the protective case 105 in FIG. 1 are combined and rotated 180 degrees along the direction X1.

In the assembled power circuit board module 10 , the socket 103 is exposed through the hole 1050 , and there is a gap 1054 between the socket 103 and the shell 105 . Therefore, when the plug of the power cord is inserted into the socket 103 along the direction X1, the soldering portion 109 between the socket 103 and the power circuit board 101 needs to bear the thrust from the plug insertion. Therefore, when an excessive thrust is applied to the plug, it is easy to cause solder cracks at the solder joint 109 between the socket 103 and the power circuit board 101 , and then cause a short circuit, making the flat panel display unable to operate.

Contents of the invention

In view of this, the purpose of the present invention is to provide a power conversion module, so that the soldered socket on the power conversion assembly will not cause tin cracks between the socket and the power conversion assembly due to excessive thrust.

According to the above purpose, the present invention proposes a power conversion module, which includes: a power conversion component, a socket, a protective shell and a support frame. The socket is arranged on the power conversion assembly in a welding manner, and the socket has a front for a plug insertion and a side, and the side is provided with a protrusion. The protective shell has a hole, and the hole runs through the protective shell. The power conversion component is arranged in the protective shell so that the side and the projection of the socket are exposed through the hole. The supporting frame has a bearing block, which is arranged outside the protective shell, and the supporting block extends into the hole of the protective shell, so that the supporting block can touch the back of the raised block and the protective shell respectively. When the plug is inserted into the front of the socket, the block of the support frame can abut against the back of the protrusion of the socket to restrict the socket from moving into the protective shell, so that the socket cannot be separated from the welding of the power conversion assembly.

The above-mentioned protective shell can also have a hook frame, which is arranged on the side of the hole, and the support frame also has a buckle hook, which is set opposite to the hook frame, and the support frame is positioned on the hook frame by buckling the hook. on the shell. The above-mentioned power conversion module can be used in flat-panel displays to convert commercial power into direct current power that can be used by flat-panel displays. And the above-mentioned power conversion component may be a power circuit board.
