[0002] Under the background of the increasingly mature industrial production level nowadays, in production and operation places such as convenience stores, banks, hospitals, offices, etc., there is a greater tendency to use electronic devices with display screens. The display screen can be used to display information, and the information can be changed according to needs. In the context of the increasingly reduced price cost, it gradually replaces traditional paper products for information display. Such an electronic device with a display screen can be an information display screen, which can display information such as product names, prices, discounts, etc. The basic components of the existing information display screen can include a display screen, a processor unit, and a power supply unit. Among them, the display screen is used to display information, the processor unit is used to control and transmit information to the display screen, and the power supply unit is used to supply power to the processor unit and the display screen. The existing power supply methods mainly include battery power supply and external power supply. Common external power supply generally needs to be connected through a power adapter and a power cord, and the display screen not only needs to be powered, but also needs to be fixed. Usually, brackets and tracks are used to fix the display screen. At this time, if the power cord is directly connected, it is less beautiful. Therefore, the prior art adopts a scheme of integrating fixing and power supply, and connects the information display screen to the track with a power supply structure through a connecting piece to achieve power supply and fixing at the same time.

[0036] Please refer to Figures 1 to 9, An electrical connection structure for an electronic device, comprising a U-shaped conductive wire 10, a circuit board 20, and an electrical connector 30. The U-shaped conductive wire can be made of a metal conductive material, such as iron wire or copper wire. The circuit board is a PCB circuit board, and the circuit board is provided with a conductive end, which can be an existing structure for circuit board conduction, such as a conductive copper foil, a socket, a pin, etc. The electrical connector is a metal contact / elastic piece or a conductive screw / conductive nut made of a metal conductive material. One end of the electrical connector is electrically connected to one end of the U-shaped conductive wire, and the other end of the electrical connector is used to be electrically connected to an external power supply. The circuit board obtains power from the external power supply through the U-shaped conductive wire and the electrical connector to achieve power supply. The circuit board is arranged inside the housing of the electronic device. It should be noted that the electronic device includes, but is not limited to, devices such as a screen, a speaker, a lamp, etc., and its housing can refer to the existing conventional structure of the corresponding device. The bottom of the U-shaped conductive wire bypasses one end of the electrical connector and is fixedly connected. The fixed connection between the U-shaped conductive wire and the electrical connector can be through welding. One end of the top of the U-shaped conductive wire is electrically connected to the conductive end of the circuit board. Specifically, the top of the U-shaped conductive wire can extend to be electrically connected to the conductive end of the circuit board, making the structural design of the circuit board and the position setting of the conductive end more flexible. The other end of the electrical connector is electrically connected to an external power supply. The external power supply can be rail power supply. For example, in the patent publication number CN114976796A, a conductive bar 22 is arranged inside the rail. The electrical connector is electrically connected to a rail connection block, and the rail connection block is electrically connected to the conductive bar inside the rail. Thus, the circuit board obtains power supply in sequence through the U-shaped conductive wire, the electrical connector, the rail connection block, and the conductive bar. The U-shaped conductive wire and the conductive end of the circuit board can be electrically connected by welding, or by socket electrical connection, or by spiral connection.

[0037] By setting the U-shaped conductive wire and the electrical connector, the bottom of the U-shaped conductive wire bypasses one end of the electrical connector and is fixedly electrically connected. At the same time, the other end of the top of the U-shaped conductive wire is electrically connected to the conductive end of the circuit board. Finally, the other end of the electrical connector is electrically connected to an external power supply to form an electrical connection structure of the electrical connector, the U-shaped conductive wire, and the circuit board. This structure can stably obtain power, without the need to set power terminals and power ports, reducing the production cost of the electronic device.

[0038] In some embodiments, the electrical connector is detachably and fixedly connected to the housing. When the electrical connector is fixed relative to the housing, the U-shaped conductive wire is clamped between the electrical connector and the electronic device. Specifically, the electrical connector can be a conductive buckle. A corresponding buckle groove is provided on the housing, and the electrical connector and the housing can be buckled, and the U-shaped conductive wire is clamped in the middle of the buckle structure, so that the electrical connector can be stably electrically connected to the U-shaped conductive wire. Preferably, the electrical connector is a conductive screw 401 and a conductive nut 402. Correspondingly, a matching threaded connection structure can be provided on the housing, or a matching threaded connection structure can be provided on the connection mechanism for power taking and fixing outside the housing. The connection mechanism can refer to the in-rail connection block in the patent with the patent publication number CN114976796A. Then, when the conductive nut of the electrical connector is inside the housing of the electronic device, the conductive nut is threadedly connected and locked with the screw, and the U-shaped conductive wire is fixed between the conductive nut and the housing of the electronic device for stable electrical connection; when the screw of the electrical connector is inside the housing of the electronic device, the screw is threadedly connected and locked with the external threaded structure or the conductive nut, and the U-shaped conductive wire is fixed between the screw head and the housing of the electronic device, and stable electrical connection can also be achieved. By using the combination of a screw and a conductive nut for the electrical connector, the electrical connection is stable, the power taking is stable, and at the same time, it is convenient for the rapid assembly of the electrical connection structure of the electronic device, and the accessory cost is low.

[0039] In some embodiments, there is also a receiving groove 31. The receiving groove 31 is arranged inside the electronic device. One end of the electrical connector is placed in the receiving groove 31, and the other end is used for connecting to an external power supply. The bottom of the U-shaped conductive wire is placed in the receiving groove 31 and electrically connected to one end of the electrical connector, that is, the U-shaped conductive wire bypasses the electrical connector to form a U-shaped structure. When the electrical connector is a conductive nut and the conductive nut is inside the housing of the electronic device, the conductive nut is placed in the receiving groove, and the internal space of the receiving groove is not less than the volume of the conductive nut; when the electrical connector is a screw and the screw head is inside the housing of the electronic device, the screw head is placed in the receiving groove. The bottom of the U-shaped conductive wire is used for electrically connecting to the electrical connector, and one end of the top of the U-shaped conductive wire close to the conductive end of the circuit board is electrically connected to the conductive end of the circuit board. By providing the receiving groove, the U-shaped conductive wire and the electrical connector can be respectively installed in the receiving groove first, and then the next assembly can be carried out, improving the production efficiency, and the receiving groove can also play a certain limiting role to improve the electrical connection stability.

[0040] Further, a wire passing groove 301 is provided in the upper part of the front side of the receiving groove. The U-shaped conductive wire can pass through the wire passing groove. The wire passing groove can be an open groove on the front side or a through groove, which can play a limiting role on the U-shaped conductive wire and improve the electrical connection stability.

[0041] Furthermore, the accommodating groove is arranged at the inner top of the housing of the electronic device, and the conductive end is arranged at the upper part of the circuit board. By arranging both the accommodating groove and the conductive end of the circuit board at the top or upper part, that is, on the same side, the wiring distance of the U-shaped conductive wire can be shortened, materials can be saved, and costs can be reduced.

[0042] Furthermore, the conductive end is arranged on the back of the circuit board. When the circuit board is assembled in the housing, the conductive end presses the U-shaped conductive wire to form an electrical connection. In this embodiment, the installation sequence is to first install the electrical connection component and the U-shaped conductive wire, and finally assemble the circuit board. After the circuit board is assembled, it is fixedly connected to the housing. By reasonably setting the distance between the circuit board and the back of the housing, the U-shaped conductive wire can be clamped and fixed. By arranging conductive ends at corresponding positions, electrical connection can be achieved immediately after assembly, which can effectively improve production efficiency.

[0043] Furthermore, inverted U-shaped portions 101 are respectively extended from the upper two ends of the U-shaped conductive wire, and the inverted U-shaped portions are used to snap onto the side walls of the accommodating groove. The inverted U-shaped portions can assist the U-shaped conductive wire to be stably clamped in the accommodating groove, improve the assembly efficiency, and improve the electrical connection stability.

[0044] The present invention also provides a display screen, including an electrical connection structure 1, an in-rail connection block 4, a track 2, and a display board 3. The electrical connection structure is an electrical connection structure of an electronic device according to any one of the above embodiments. The display board is an electronic device. The in-rail connection block is placed in the track and electrically connected to the track. The electrical connection component of the in-rail connection block is electrically connected to the electrical connection component. The in-rail connection block is fixedly connected to the display board. The display board is an existing screen for displaying content, such as an LCD or OLED screen. The in-rail connection block and the track can refer to the in-rail connection block in the patent with the publication number CN114976796A, but are not limited to the specific structure in this reference patent. Structures in the prior art that can achieve the same or similar functions and effects can be adopted.

[0045] A clamping mechanism 5 is provided on the outer side of the in-rail connection block 4. The clamping mechanism 5 protrudes from the side surface of the in-rail connection block 4 and is used to clamp the inner side wall of the track 2. The clamping mechanism 5 can protrude from only one side surface of the in-rail connection block 4. In this case, the other side surface corresponding to the clamping mechanism 5 can be closely attached to the inner wall surface of the other side of the track 2 to achieve clamping. The width inside the track 2 is slightly wider than the front-back width of the in-rail connection block 4, so that the in-rail connection block 4 is exactly located inside the track 2. Thus, as long as the clamping mechanism 5 on at least one side protrudes and is clamped in the card slot 21, the clamping of the in-rail connection block 4 inside the track 2 can be achieved. Preferably, there are two clamping mechanisms 5 on the front and back side surfaces of the in-rail connection block 4. The two clamping blocks are respectively arranged at both ends of the in-rail connection block 4 to avoid unstable shaking of the in-rail connection block 4 after clamping, making the clamping more stable. Preferably, the clamping mechanism 5 symmetrically protrudes from both side surfaces of the in-rail connection block 4, so there is no need to distinguish the installation direction, and clamping can be carried out in both the correct and reverse installations, which is more convenient and fast. A card slot 21 is provided on the inner side wall of the track 2. The clamping mechanism 5 can be clamped in the card slot 21 on the inner side wall of the track 2. The direction of the card slot 21 on the inner side wall of the track 2 extends parallel to the length direction of the track 2. Therefore, the clamping mechanism 5 can be clamped with the track 2 at any position, that is, the in-rail connection block 4 can be installed at any position on the track 2. It should be noted that the side surface of the in-rail connection block 4 refers to the side surface that comes into contact with the inner side surface of the track 2.

[0046] Further, the in-rail connection block is fixedly connected and electrically connected to the display board through the electrical connection member. The electrical connection member can provide a fixed connection function in addition to the power-taking function, without the need to additionally set a fixed connection structure, further reducing costs.

[0047] It should be noted that although the above-mentioned embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, the changes and modifications made to the embodiments described in this article, or the equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present invention.
