In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0031] As Figure 1 and Figure 2 shown, the present embodiment provides a connecting device for connecting adjacent first box body 1 and second box body 2. The connecting device includes a first connecting member 10 and a second connecting member 20. The first connecting member 10 is electrically connected to the first box body 1; the second connecting member 20 is electrically connected to the second box body 2; wherein, the first connecting member 10 and the second connecting member 20 are plugged and mated and electrically connected; the first connecting member 10 includes a first body portion 11 and a control switch 12, and the control switch 12 is arranged on the first body portion 11, and the control switch 12 controls the on-off between the first connecting member 10 and the second connecting member 20.

[0032] In this embodiment, since the control switch 12 is provided on the first connecting member 10, the on-off of the electrical connection between the first box body 1 and the second box body 2 can be controlled externally, without the need to connect or disassemble wires, thereby simplifying the assembly and connection method between the first box body 1 and the second box body 2, avoiding leaving a wire connection position on the box body. Especially when the power supply is fully loaded, the corresponding box body can be disconnected through the control switch 12, realizing the on-off control between box bodies, meeting the use requirements, and having simple operation and beautiful appearance.

[0033] As Figure 6As shown, in this embodiment, the first connector 10 further includes a power supply connection portion 13, which is provided on the first body portion 11 and is connected to an external power supply device.

[0034] Since the power supply connection portion 13 is provided, it is convenient for the first connector 10 to be connected to the external power supply device and supply power to the first box body 1, simplifying the power supply connection structure.

[0035] As Figures 2 to 4 shown, in this embodiment, the connection device further includes a pin 30 and a jack 14. The pin 30 is provided on one of the first connector 10 and the second connector 20, and the jack 14 is provided on the other of the first connector 10 and the second connector 20.

[0036] Specifically, the pin 30 in this embodiment is inserted into the jack 14 to achieve electrical conduction between the first connector 10 and the second connector 20 when the first connector 10 and the second connector 20 are plugged and mated.

[0037] Preferably, the pin 30 in this embodiment is a spring pin (such as a POGO PIN). The pin 30 is provided on the second connector 20, and the jack 14 is provided at the lower end of the first connector 10. In an alternative embodiment not shown in the drawings, the pin can also be provided on the first connector and the jack on the second connector, as long as electrical conduction can be achieved when the first connector 10 and the second connector 20 are plugged and mated.

[0038] The on-off of the electrical signal between the first connector and the second connector is realized through the telescopic function of the POGO Pin. Adding a switch inside the first connector can cut off the power between the second box body 2 and the first box body 1 in the state where the first connector and the second connector are connected, and simultaneously introduce an external power supply to supply power to the second box body 2, realizing separate control without additional wiring operations.

[0039] Further, two rows of pins 30 are provided on the second connector 20 in this embodiment, and the number of pins 30 in each row is greater than or equal to two. This setting realizes the synchronous plugging and unplugging of the first connector 10 and the second connector 20 in the X direction and Y direction of the plane. In the powered state, by operating the control switch 12, the power on or off between the first box body 1 and the second box body 2 can be realized, meeting the need for on-off control.

[0040] As Figure 3 and Figure 4As shown, in this embodiment, the pin 30 is provided on the second connector 20. The second connector 20 includes a second body portion 21, a top plate 23, an elastic structure 24, and a mounting post 25. Among them, a mounting seat 22 for mounting the pin 30 is provided on the second body portion 21; the top plate 23 is fixedly connected to the second body portion 21; the elastic structure 24 is disposed below the top plate 23, and the upper end of the elastic structure 24 abuts against the top plate 23; the mounting post 25 is connected to the top plate 23. The mounting post 25 includes a column body and a stop plate provided at the lower end of the column body. The elastic structure 24 is sleeved on the column body. The first end of the elastic structure 24 abuts against the stop plate, and the second end of the elastic structure 24 abuts against the top plate 23. Among them, the length of the column body is less than the initial length of the elastic structure 24.

[0041] In this embodiment, the top plate 23 is fixedly connected to the second body portion 21, and the elastic structure 24 is compressed between the top plate 23 and the stop plate, so that the elastic structure 24 has an upward elastic force on the top plate 23, and then applies an upward force on the second body portion 21, making the entire second connector 20 tend to be close to the first connector 10. When the first connector 10 and the second connector 20 are inserted and mated, the cooperation between the pin 30 and the jack 14 is tighter, ensuring that the electrical conduction effect of the pin 30 is more stable.

[0042] Preferably, the elastic structure 24 of this embodiment is a spring, and the elastic force of the spring on the top plate 23 is greater than the sum of the self-weight of the second connector 20 and the elastic force of the spring pin. The above setting can make the elastic pre-tightening force of the spring overcome the self-weight of the second connector 20 and the elastic force of the spring pin, and make the electrical conduction effect of the spring pin stable.

[0043] As Figure 3 and Figure 5 shown, in this embodiment, the second connector 20 further includes a protective cover 26. The protective cover 26 is connected to the top plate 23 and covers the outer periphery of the elastic structure 24. There is a gap between the protective cover 26 and the second body portion 21.

[0044] Specifically, due to the provision of the protective cover 26 and the gap between the protective cover 26 and the second body portion 21, the downward elastic force of the elastic structure 24 on the stop plate will not be applied to the second body portion 21, ensuring that the entire second connector 20 has a definite tendency to approach the first connector 10, and ensuring the stable contact of the pin 30.

[0045] As Figure 3 、 Figure 4 and Figure 8As shown, in this embodiment, the second connector 20 further includes a limiting post 27. The limiting post 27 is disposed on the top plate 23, and the limiting post 27 protrudes from the first body portion 11 in the vertical direction. The second box body 2 is provided with an avoidance hole corresponding to the limiting post 27, and the outer wall of the first box body 1 is provided with an avoidance groove corresponding to the limiting post 27.

[0046] Due to the provision of the limiting post 27, when the second connector 20 is installed on the second box body 2, the limiting post 27 passes through the avoidance hole and is correspondingly engaged with the avoidance groove.

[0047] Specifically, there are two top plates 23 in this embodiment. The two top plates 23 are disposed on both sides of the second body portion 21, and each top plate 23 is provided with two limiting posts 27.

[0048] Through the above settings, the limiting post 27 can play a limiting role when the first connector 10 and the second connector 20 are inserted and engaged, preventing installation misalignment from affecting the electrical conduction effect of the pin 30.

[0049] As Figure 1 、 Figure 2 and Figure 5 shown, in this embodiment, the first connector 10 further includes a protective cover body 15 covering the power supply connection portion 13.

[0050] The above settings can play a protective role for the power supply connection portion 13, preventing users from being strongly electrocuted and ensuring the use safety of users. Preferably, the protective cover body 15 in this embodiment is a plastic part.

[0051] As Figure 2 shown, in this embodiment, the first connector 10 further includes ear plates 16 disposed on both sides of the first body portion 11. The ear plates 16 are provided with first connection holes 17, and the first box body 1 is provided with second connection holes corresponding to the first connection holes 17. The connection device further includes a first fastener, and the first fastener passes through the first connection hole 17 and the second connection hole to connect the first connector 10 and the first box body 1.

[0052] The above settings ensure the connection strength between the first connector 10 and the first box body 1

[0053] As Figure 3 shown, in this embodiment, the protective cover 26 is provided with a third connection hole 28, and the second box body 2 is provided with a fourth connection hole corresponding to the third connection hole 28. The connection device further includes a second fastener, and the second fastener passes through the third connection hole 28 and the fourth connection hole to connect the second connector 20 and the second box body 2.

[0054] The above settings ensure the connection strength between the second connecting member 20 and the second box body 2, thereby ensuring that when the first connecting member 10 and the second connecting member 20 are respectively installed on the first box body 1 and the second box body 2, the first connecting member 10 and the second connecting member 20 can be stably inserted and matched, and further ensuring the stability of the power-on or power-off control between the first connecting member 10 and the second connecting member 20.

[0055] As Figure 7 shown, this embodiment also provides an LED display device, including a first box body 1, a second box body 2, and a connecting device connecting adjacent first box bodies 1 and second box bodies 2, and the connecting device is the above-mentioned connecting device.

[0056] In this embodiment, since the control switch 12 is provided on the first connecting member 10, the on-off of the electrical connection between the first box body 1 and the second box body 2 can be controlled externally, without connecting or disassembling the wires, thereby simplifying the assembly and connection method between the first box body 1 and the second box body 2, and avoiding leaving a wiring position for the wires on the box body. Especially when the power supply is fully loaded, the corresponding box body can be disconnected through the control switch 12, realizing the combined and separated control between the box bodies, meeting the use requirements, and having simple operation and beautiful appearance.

[0057] Therefore, the LED display device with the above-mentioned connecting device also has the above-mentioned advantages.

[0058] It should be noted that if one box body in the LED display device is clamped between the other two box bodies, then a first connecting member and a second connecting member are respectively provided on the two opposite sides of the box body to be respectively inserted and matched with the second connecting member and the first connecting member of the adjacent box bodies.

[0059] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0060] Since the control switch is provided on the first connecting member, the on-off of the electrical connection between the first box body and the second box body can be controlled externally, without connecting or disassembling the wires, thereby simplifying the assembly and connection method between the first box body and the second box body, and avoiding leaving a wiring position for the wires on the box body. Especially when the power supply is fully loaded, the corresponding box body can be disconnected through the control switch, realizing the combined and separated control between the box bodies, meeting the use requirements, and having simple operation and beautiful appearance.

[0061] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures.

Thus, the exemplary term "above" can include both orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations for the spatial relative descriptions used herein will be made accordingly.

[0062] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present invention.

[0063] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
