DETAILED DESCRIPTION

[0038] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0039] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] Example 1

[0042] Combine Figures 1 to 4 , schematically shows the power supply device of the present invention, including a first installation component 10, a second installation component 20 and a limiting component.

[0043] The first mounting component 10 is provided with a pin 11, and the second mounting component 20 is provided with a socket 21. The pin 11 is plugged into the socket 21 to achieve an electrical connection between the first mounting component 10 and the second mounting component 20. No cables are required to connect the two, thus avoiding the clutter of the internal space caused by the large number of cables arranged within the power supply device. The limit assembly includes a detachably engageable limit block 22 and a limit slot 12. One of the limit block 22 and the limit slot 12 is provided on the first mounting component 10, and the other is provided on the second mounting component 20. The arrangement of the limit block 22 and the limit slot 12 prevents the first mounting component 10 and the second mounting component 20 from being assembled at an incorrect angle, thus preventing errors.

[0044] In this embodiment, the first mounting member 10 may be a portion of the housing of the power supply device, and the second mounting member 20 may be another portion of the housing of the power supply device. When assembled, the two members form a complete housing of the power supply device. The first mounting member 10 may also be one of the electronic components 70 in the power supply device (or an independent component of the electronic component 70), and the second mounting member 20 may also be another electronic component 70 in the power supply device (or an independent component of the electronic component 70), thereby achieving the structural assembly and electrical connection of the two electronic components 70 described above.

[0045] Specifically, the jacks 21 and the pins 11 are provided in multiple numbers and the number is the same, such as Figure 3 and Figure 4 In this embodiment, three sockets 21 are provided, namely, a positive socket 211, a negative socket 212, and a grounding socket 213; three pins 11 are provided, namely, a positive pin 111, a negative pin 112, and a grounding pin 113. Each pin 11 corresponds to a socket 21. The layout of the sockets 21 and the pins 11 can be connected to a 220V circuit. For example, the live wire of the mains is connected to the positive pin 111, the neutral wire of the mains is connected to the negative pin 112, and the ground wire of the mains is connected to the grounding pin 113. After the first mounting component 10 and the second mounting component 20 are assembled with each other, each socket 21 can also be connected to the 220V mains. A limiting groove 12 is provided on the first mounting component 10, and a limiting block 22 is provided on the second mounting component 20. The limiting groove 12 and the limiting block 22 can enable the first mounting component 10 and the second mounting component 20 to be assembled with each other at a correct angle to prevent the positive pin 111, the negative pin 112 and the ground pin 113 from being connected to the wrong socket 21 and causing the circuit to burn out.

[0046] One pair of pins 11 and sockets 21 is used for grounding and is collectively referred to as a grounding group. Specifically, grounding pins 113 and grounding sockets 213 are collectively referred to as the grounding group. When the first and second mounting components 10 and 20 move toward each other (during the assembly process), the pins 11 and sockets 21 in the grounding group come into contact before the other pins 11 (i.e., positive pin 111 and negative pin 112) and sockets 21 (i.e., positive sockets 211 and negative sockets 212). This ensures that the grounding wire is connected first, ensuring electrical safety. Specifically, the ground pin 113 can be longer than the other pins 11 (positive pin 111 and negative pin 112), while the lengths of all sockets 21 are the same. Alternatively, the ground socket 213 can be longer than the other sockets 21 (positive socket 211 and negative socket 212), specifically manifested in that the end of the ground socket 213 protrudes more than the other sockets 21, while the lengths of all pins 11 are the same. Alternatively, the ground pin 113 can be longer than the other pins 11 (positive pin 111 and negative pin 112), while the ground socket 213 can be longer than the other sockets 21 (positive socket 211 and negative socket 212). The above pin 11 and socket 21 structural combinations can all achieve contact between the pins 11 and sockets 21 in the grounding group before the other pins 11 and sockets 21.

[0047] Example 2

[0048] like Figure 1 and Figure 2 This embodiment differs from the first embodiment in that the first mounting component 10 is provided with a protective hole 13 made of an insulating material, such as plastic, and a pin 11 is disposed within the protective hole 13. The second mounting component 20 is provided with a protective block 23 made of an insulating material, such as plastic, and having a socket 21 formed at its end. The protective block 23 is removably plugged into the protective hole 13, and the pin 11 is plugged into the socket 21. The protective hole 13 protects the pin 11 from being exposed and subjected to accidental impact, and the protective block 23 is used to position the socket 21, thereby preventing the conductor within the socket 21 from being exposed.

[0049] The protection hole 13 and the protection block 23 are both made of insulating material, which can provide external protection for the conductors in the pin 11 and the socket 21 to prevent the conductors from accidentally connecting to other structures and causing leakage.

[0050] Example 3

[0051] Combine Figures 5 to 8As shown, the power supply device of this embodiment includes a first housing 30 and a second housing 40. The first mounting member 10 is detachably connected to the first housing 30, and the second mounting member 20 is detachably connected to the second housing 40. When the pin 11 is inserted into the socket 21, the first housing 30 and the second housing 40 interlock, forming a complete power supply device housing.

[0052] like Figure 5 and Figure 6 The first mounting component 10 is a separate component connected to the first housing 30. The first mounting component 10 is electrically connected to the electronic components 70 on the first housing 30. Specifically, the electronic components 70 on the first housing 30 are electrically connected to the pins 11 on the first mounting component 10. The second mounting component 20 is a separate component connected to the second housing 40. The second mounting component 20 is electrically connected to the electronic components 70 on the second housing 40. Specifically, the electronic components 70 on the second housing 40 are electrically connected to the sockets 21 on the second mounting component 20. Therefore, after the first housing 30 and the second housing 40 are fastened together, the pins 11 are inserted into the sockets 21, achieving synchronous splicing of the first mounting component 10 and the second mounting component 20.

[0053] Further, combined with Figure 1 and Figure 8 As shown, the first mounting component 10 is provided with a first connecting post 14 and a second connecting post 15, both for connecting to the first housing 30. The length of the first connecting post 14 is greater than that of the second connecting post 15. Correspondingly, a first mounting post 31 and a second mounting post 32 are provided on the inner wall of the first housing 30. The end of the first connecting post 14 is detachably connected to the end of the first mounting post 31, and the end of the second connecting post 15 is detachably connected to the end of the second mounting post 32, thereby achieving a detachable connection between the first mounting component 10 and the first housing 30. The inconsistency between the lengths of the first connecting post 14 and the second connecting post 15 can effectively prevent the first mounting component 10 from being installed at an incorrect angle in the first housing 30. The extension direction of the first connecting post 14 (and the second connecting post 15) is opposite to the extension direction of the pin 11.

[0054] Combine Figure 2 and Figure 7As shown, the second mounting component 20 is provided with a third connecting post 24 and a fourth connecting post 25, both for connecting to the second housing 40. The length of the third connecting post 24 is greater than that of the fourth connecting post 25. Correspondingly, a third mounting post 41 and a fourth mounting post 42 are provided on the inner wall of the second housing 40. The end of the third connecting post 24 is detachably connected to the end of the third mounting post 41, and the end of the fourth connecting post 25 is detachably connected to the end of the fourth mounting post 42, thereby achieving a detachable connection between the second mounting component 20 and the second housing 40. The inconsistent length of the third connecting post 24 and the fourth connecting post 25 can effectively prevent the second mounting component 20 from being installed at an incorrect angle in the second housing 40. The third connecting post 24 (and the fourth connecting post 25) are arranged opposite to the jack 21.

[0055] Example 4

[0056] Combine Figures 9 to 11 As shown, if there are more plug-in positions between the electronic components 70 on the first shell 30 and the electronic components 70 on the second shell 40 (or more pairs of first mounting parts 10 and second mounting parts 20 are provided), it will inevitably lead to difficulty in disassembling the first shell 30 and the second shell 40.

[0057] The difference between this embodiment and embodiment 3 is that the power supply device includes a pushing assembly, and the pushing assembly includes a pushing block 43 and a pushing mechanism.

[0058] like Figure 10 The pushing mechanism includes a connecting base 33 and a transmission member 34. The transmission member 34 is connected to the connecting base 33 via a transmission structure. When the transmission member 34 and the connecting base 33 rotate relative to each other, the transmission structure drives the two to move relative to each other along a straight line. The end of the transmission member 34 is used to abut against the push block 43. One of the push block 43 and the connecting base 33 is connected to the first mounting component 10, and the other is connected to the second mounting component 20.

[0059] When removing the first mounting component 10 and the second mounting component 20, force is applied to rotate the transmission member 34 so that it rotates relative to the connecting seat 33. The transmission structure drives the transmission member 34 and the connecting seat 33 to move relative to each other along a straight line. The end of the transmission member 34 pushes the pushing block 43 to force the first mounting component 10 and the second mounting component 20 to move away from each other. The pushing assembly can make it easier to remove the first mounting component 10 and the second mounting component 20.

[0060] Among them, combined Figure 10 and Figure 11As shown, the transmission structure includes a transmission block 331 mounted on the connecting base 33 and a guide groove 341 mounted on the transmission member 34. The guide groove 341 is spirally arranged, and the transmission block 331 is slidably embedded in the guide groove 341. When force is applied to rotate the transmission member 34, the transmission block 331 slides in the spiral guide groove 341, forcing the transmission member 34 and the connecting base 33 to move relative to each other along a straight line. In this embodiment, a handle 342 is provided on the transmission member 34 to facilitate installation and maintenance personnel to apply force to the transmission member 34.

[0061] In order to reset the transmission member 34 to prepare for the next pushing operation, the pushing mechanism includes an elastic member 50, which is preferably a torsion spring. The elastic member 50 is respectively connected to the connecting seat 33 and the transmission member 34. When the installation and maintenance personnel apply force to twist the transmission member 34, the transmission member 34 rotates forward relative to the connecting seat 33, which will overcome the elastic force of the elastic member 50; when the installation and maintenance personnel stop applying force to the transmission member 34, the elastic force of the elastic member 50 drives the transmission member 34 to rotate in the opposite direction relative to the connecting seat 33 to reset.

[0062] In this embodiment, there are two pushing assemblies, which are respectively located on both sides of the first installation component 10 (or the second installation component 20).

[0063] Example 5

[0064] Combine Figure 12 As shown, this embodiment provides a display device, including a display module 60 and the power supply device as described above. The power supply device is arranged on the back of the display module 60, and the front of the display module 60 is used for displaying images.

[0065] To sum up, the first mounting component 10 of the power supply device is provided with a pin 11, and the second mounting component 20 is provided with a socket 21. A limiting block 22 is provided on one of the first mounting component 10 and the second mounting component 20, and a limiting slot 12 is provided on the other. When the first mounting component 10 and the second mounting component 20 are assembled with each other, the limiting block 22 is aligned with the limiting slot 12 to prevent the first mounting component 10 and the second mounting component 20 from being assembled with each other at a wrong angle. The pin 11 is plugged into the socket 21 to realize the electrical connection between the first mounting component 10 and the second mounting component 20, so that there is no need to use a large number of cables in the power supply device, so as to facilitate the rapid assembly of the power supply device.

[0066] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
