[0001] This utility model relates to the field of PCB board technology, specifically to a PCB board mounting structure for new energy charging equipment. Background Technology

[0002] A circuit board is composed of integrated circuits, a quartz oscillator, trimmer capacitors, and a printed circuit board. Circuit boards are also known as ceramic circuit boards, alumina ceramic circuit boards, and aluminum nitride ceramic circuit boards. Circuit boards miniaturize and simplify circuits, playing a crucial role in the mass production of fixed circuits and optimizing the layout of electrical appliances. Currently, for PCB boards in new energy device chargers, multiple screws are required to secure the PCB board to the charger casing, which slows down the installation process and hinders installation and removal. Therefore, this paper proposes a PCB board mounting structure for new energy charging equipment to solve these problems. Utility Model Content

Detailed Implementation

[0016] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to the following: Figures 1-4 This utility model discloses a PCB board mounting structure for a new energy charging device, comprising: a PCB board body 1; a connecting post 2 sleeved at the corner of the PCB board body 1; a limiting groove 3 longitudinally formed inside the connecting post 2; a limiting post 4 longitudinally slidably sleeved inside the limiting groove 3; a first magnetic clip 5 slidably sleeved inside the connecting post 2 at the lower end of the PCB board body 1; a second magnetic clip 6 slidably sleeved inside the connecting post 2 on the side opposite the first magnetic clip 5; a spring 9 provided on the upper end of the limiting post 4 inside the limiting groove 3; and a heat dissipation copper pipe 12 penetrating inside the PCB board body 1. The heat dissipation copper pipe 12 increases the heat dissipation area of ​​the PCB board body 1, thereby facilitating the outward dissipation of heat from the PCB board body 1.

[0020] Combination Figure 4As shown, the first magnetic clip 5 and the second magnetic clip 6 are both inclined at opposite ends. The first magnetic clip 5 and the second magnetic clip 6 are magnetically connected. The docking post 2 is provided with a limiting block 8 on one side of the bottom of the first magnetic clip 5 and the second magnetic clip 6. The bottom of the first magnetic clip 5 and the second magnetic clip 6 are provided with a slot 7. The limiting block 8 is slidably engaged inside the slot 7. The slot 7 and the limiting block 8 can limit the range of motion of the first magnetic clip 5 and the second magnetic clip 6 to prevent them from coming out. When the limiting post 4 is lifted, the first magnetic clip 5 and the second magnetic clip 6 are magnetically attracted and automatically retract into the docking post 2, making it easy and quick to remove the docking post 2 from the sleeve 13.

[0021] The bottom end of the docking post 2 is inserted into the top of the sleeve 13. The inner ring of the sleeve 13 is provided with an annular slot 14 on the side facing the first magnetic head 5 and the second magnetic head 6. The first magnetic head 5 and the second magnetic head 6 are both engaged in the annular slot 14. The sleeve 13 is fixedly connected to the bottom of the charger housing 16. A cooling fan 17 is provided inside one end of the charger housing 16. Several cooling copper pipes 12 are provided. The cooling copper pipes 12 do not intersect with the internal circuit of the PCB board body 1, thereby ensuring that the cooling copper pipes 12 do not affect the normal operation of the PCB board body 1. The docking post 2 is located on the upper outer side of the PCB board body 1 and is threaded with a nut 15, which facilitates fixing the docking post 2 at the corner of the PCB board body 1. The top of the limiting post 4 is connected with a pull ring 11, and the bottom of the limiting post 4 has a conical structure.

[0022] Specifically, when installing the PCB board body 1, the pull ring 11 is first manually dragged, which moves the pull ring 11 along with the limiting post 4 and compresses the spring 9. Then, the docking post 2 of the dragged pull ring 11 at the bottom corner of the PCB board body 1 is aligned and inserted into the top of the sleeve 13. After insertion, the pull ring 11 is stopped, and the limiting post 4 is pushed under the elastic force of the spring 9. The conical bottom end of the limiting post 4 can push the first magnetic clip 5 and the second magnetic clip 6 outward simultaneously, so that the first magnetic clip 5 and the second magnetic clip 6 are engaged in the annular slot 14 inside the sleeve 13, thus completing the installation of the PCB board body 1.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
