Detailed Description
It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict, and the present invention is further described in detail with reference to the accompanying drawings and specific embodiments.
In the embodiment of the present invention, if there is directional indication (such as upper, lower, left, right, front, and rear … …) only for explaining the relative position relationship between the components and the motion situation under a certain posture (as shown in the drawing), if the certain posture is changed, the directional indication is changed accordingly.
In addition, the descriptions of the first, second, etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying any relative importance or implicit indication of the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.
Referring to fig. 1 to 4, a low power module power supply according to an embodiment of the present invention includes a circuit board, a bottom plate, and a top cover.
The outside of top cap both sides bottom respectively has one section protruding muscle, and the bottom plate middle part is equipped with the encapsulating hole, and the bottom plate both sides are equipped with the clamping part that corresponds with the top cap, and the clamping part inboard is equipped with the recess that corresponds with protruding muscle. The top cover is arranged on the bottom plate to realize sealing and has beautiful appearance. The convex ribs on the two sides of the top cover are correspondingly embedded into the grooves. The top cover is internally provided with a step matched with the periphery of the circuit board. The circuit board is arranged in the top cover, and the top surface of the circuit board is bonded with the step. And heat-conducting glue is filled between the circuit board and the bottom plate.
