Description

Technical Field

[0001] The invention relates to the field of track power taking devices, and in particular to a cost-saving track power taking device and an information display screen. Background Art

[0002] In the context of today's increasingly mature industrial production level, in production and operation sites such as convenience stores, banks, hospitals, and offices, people are more inclined to use electrical devices with display screens. Display screens can be used to display information, and the information can be changed according to demand. In the context of increasingly lower price costs, they gradually replace traditional paper products for displaying information. This electrical device with a display screen can be an information display screen that can display information such as product names, prices, discounts, etc. The basic components of the existing information display screen may 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 provide 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 powered by a power adapter and a power cord, while the display screen not only needs power supply, but also needs to be fixed. Usually, a bracket and a track are used to fix the display screen. At this time, if the power cord is directly connected, it is not beautiful. Therefore, the prior art adopts a solution of integrated fixing and power supply, and the information display screen is connected to a track with a power supply structure through a connector to achieve power supply and fixation at the same time.

[0042] See also Figures 1 to 11The present invention provides a cost-saving rail power supply device 1, comprising an in-rail connection block 10, a sliding member 20, an equipment connection member 30 and a conductive mechanism 40; the in-rail connection block 10 is a rectangular box-shaped structure. The sliding member 20 is arranged inside the end of the in-rail connection block 10, that is, inside one end or both ends. The sliding member 20 can slide laterally relative to the in-rail connection block 10. Preferably, the sliding member 20 can be arranged inside the in-rail connection block 10, and the structure of the in-rail connection block 10 is used to limit it so that the sliding member 20 can only slide laterally. Here, the horizontal direction refers to the length direction along the in-rail connection block 10, and correspondingly, the vertical direction is the direction perpendicular to the bottom surface of the in-rail connection block 10. The sliding member 20 includes a pressing portion 201, which can be a flat surface for easy pressing with fingers. The pressing portion 201 has a swing arm 202 extending in a lateral direction toward the inside of the inner-rail connecting block 10. The swing arm 202 should extend toward the inside of the inner-rail connecting block 10. The swing arm 202 can be strip-shaped and should have a certain length. By utilizing its own deformation ability (such as plastic), its end portion can swing to a certain extent.

[0043] The outer side of the swing arm 202 is provided with a clamping block 203, which protrudes from the side of the inner rail connection block 10 and is used to clamp the inner side wall of the track 2. The clamping block 203 can only protrude from one side of the inner rail connection block 10. In this case, the other side corresponding to the clamping block 203 is close to the inner wall surface of the track 2 on the other side to achieve clamping. The width of the inner side of the track 2 is slightly wider than the front and rear width of the inner rail connection block 10, so that the inner rail connection block 10 is just inside the track 2. In this way, as long as the clamping block 203 on at least one side protrudes and is clamped in the clamping groove 21, the clamping of the inner rail connection block 10 in the track 2 can be achieved. The clamping blocks 203 on the front and rear sides of the inner rail connection block 10 are preferably two, and the two clamping blocks are respectively arranged at the two ends of the inner rail connection block 10 to avoid unstable shaking of the inner rail connection block 10 after clamping, and the clamping is more stable. Preferably, the snap-in blocks 203 protrude symmetrically from the two side surfaces of the in-rail connecting block 10, so there is no need to distinguish the installation direction, and the snap-in can be performed in either forward or reverse installation, which is more convenient and quicker. A snap-in slot 21 is provided on the inner side wall of the track 2, and the snap-in block 203 can be snap-into the snap-in slot 21 of the inner side wall of the track 2. The direction of the snap-in slot 21 of the inner side wall of the track 2 is parallel to and extends along the length direction of the track 2. Therefore, the snap-in block 203 can be snap-into with the track 2 at any position, that is, the in-rail connecting block 10 can be installed at any position of the track 2. It should be noted that the side surface of the in-rail connecting block 10 refers to the side surface that contacts the inner side surface of the track 2, that is, the side surface of the in-rail connecting block 10. Figure 5The pressing portion 201, the swing arm 202 and the clamping block 203 are an integrally formed structure or are spliced ​​to form a whole, forming a whole sliding member 20. At least a portion of the sliding member 20 is inserted into the inner rail connecting block 10, and the portion includes a section of the swing arm 202 and the clamping block 203. The side of the inner rail connecting block 10 is correspondingly provided with an opening for the clamping block 203 to protrude out of the side.

[0044] A guide post 204 is provided at the end of the swing arm 202. Specifically, a guide post 204 is provided at the other end of the swing arm 202 away from the pressing portion 201. The guide post 204 is cylindrical, and its length extends in an upward and / or downward direction, that is, the guide post 204 is provided at the upper edge and / or the lower edge of the swing arm 202. A slide rail groove 104 is provided on the inner bottom surface and / or the inner top surface of the inner rail connection block 10. The width of the slide rail groove 104 is slightly larger than the diameter of the guide post 204. The guide post 204 can be placed in the slide rail groove 104. The slide rail groove 104 can be straight, arc or broken line, and only needs to guide the guide post 204 to move inward when the sliding member 20 slides inward. The guide column 204 of the swing arm 202 is inserted into the slide rail groove 104. The sliding member 20 slides toward the inner side of the inner rail connecting block 10 after being subjected to force. During the sliding process, the guide column 204 is limited by the groove wall of the slide rail groove 104, driving the swing arm 202 to swing inward, thereby driving the clamping block 203 to be retracted into the interior of the inner rail connecting block 10.

[0045] The direction of the slide rail groove 104 is to approach the inside along the direction in which the slide member 20 slides inward, that is, when the slide member 20 slides inwardly of the inner rail connection block 10, the guide column 204 slides in the slide rail groove 104, driving the end of the swing arm 202 to swing inwardly, and the connection block is driven by the swing arm 202 to move inwardly, so that the connection block is received into the inner rail connection block 10. At this time, the inner rail connection block 10 cannot be engaged with the track 2. It can be installed or removed; when the in-rail connection block 10 needs to be assembled, that is, to be snapped with the rail 2, it is only necessary to place the in-rail connection block 10 into the rail 2, and slide the sliding member 20 in the opposite direction, and the guide column 204 slides in the opposite direction in the slide rail groove 104, driving the end of the swing arm 202 to swing outward, and the connection block is driven by the swing arm 202 to move outward to the outside of the in-rail connection block 10 and snap into the snap slot 21 in the rail 2 to achieve snap connection. It should be noted that the sliding of the sliding member 20 in both the in-and-out directions of the in-rail connection block 10 can be achieved by manual operation, which can be achieved by applying a force in the opposite direction to the pressing part 201 by manpower. The final function of the sliding member 20 is that when it is pushed in, it drives the snap block 203 to be retracted into the in-rail connection block 10, and when it is pulled out or popped out, it drives the snap block 203 to protrude from the outside of the in-rail connection block 10.

[0046] When the present invention is in use, it is only necessary to install the sliding member 20 into the inner-rail connecting block 10 and place the guide column 204 into the slide rail groove 104 to complete the assembly. Preferably, the end opening of the inner-rail connecting block 10 is small on the outside and large on the inside. The sliding member 20 can be installed from the inside of the inner-rail connecting block 10 and then slide toward the end to complete the assembly. The end of the inner-rail connecting block 10 can clamp the sliding member 20 to prevent it from popping out and falling off.

[0047] The device connector 30 is arranged at the bottom of the rail connection block 10, and the lifting of the electrical device can be achieved by fixing the device connector 30 with the electrical device. The conductive mechanism 40 is arranged at the top or side of the rail connection block 10, and can be directly contacted by a spring piece or electrically connected to the conductive strip 22 in the track 2 by a brush or a wire, that is, an electrical connection is formed. The device connector 30 is used to fix and electrically connect with the electrical device. One end of the conductive mechanism 40 is electrically connected to the device connector 30 inside the rail connection block 10, and the other end is electrically connected to the conductive strip 22 in the track 2. The device connector 30 can be provided with an electrical connection terminal, one end of which is electrically connected to the conductive strip 22 in the track 2 by a metal spring piece or a wire, and the other end is plugged into the electrical connection port of the electrical device to obtain power. The power supply method can use interfaces such as USB-A / USB-C, and communication can be performed in addition to power supply; in a scenario where communication is not required, in order to save costs, only conductive materials can be used to directly connect the conductive strip 22 to the electrical device.

[0048] The present invention sets a slide rail groove 104 in the track 2 connecting block, and configures the sliding member 20 as a structural combination of a pressing portion 201, a swing arm 202, a clamping block 203 and a guide column 204. The guide column 204 is guided by the slide rail groove 104. When the pressing portion 201 receives a pulling force or a pushing force, the swing arm 202 swings outward or inward along with the guide column 204, driving the clamping block 203 to protrude or be retracted into the track connecting block 10, thereby realizing the clamping and separation of the track connecting block 10 and the track 2. This structure only requires one component to realize the functions of quick installation and disassembly, and multiple components are reduced to one component. The assembly process is simple, the assembly difficulty is low, and the production cost is reduced. The guide rail groove that plays a guiding role is a fixed component and is more stable.

[0049] The electrical device may be an electrical device that requires power supply and fixed connection, such as camera equipment, network equipment, wind power equipment, solar power equipment, and lighting equipment.

[0050] In some embodiments, a reset mechanism 70 is further included, and the reset mechanism 70 is arranged inside the inner rail connection block 10 and connected to the clamping block 203 or the sliding member, and the reset mechanism 70 is used to drive the clamping block 203 to move toward the side protruding from the inner rail connection block 10 through its own restoring force. The reset mechanism 70 can be a return structure in various forms, such as spring 703 reset, motor drive reset, magnetic reset or electromagnetic reset. In order to control costs, preferably, the reset mechanism 70 includes a first fixing portion 701, a spring 703 and a second fixing portion 702, the first fixing portion 701 is arranged on the inner side surface of the pressing portion 201, the second fixing portion 702 is arranged on the inner bottom surface of the inner rail connection member, and the two ends of the spring 703 are respectively fixed by the first fixing portion 701 and the second fixing portion 702. Therefore, under the condition of no external force, the sliding member 20 is located at the outermost end of the end of the inner-rail connecting member. At this time, the clamping block 203 protrudes from the side of the inner-rail connecting member. By applying a thrust to the pressing part 201, the clamping block 203 is retracted into the interior of the inner-rail connecting member. At this time, the spring 703 is compressed. After being installed in the track 2, the thrust is removed, and the spring 703 releases its elastic potential energy, pushing the sliding member 20 back to the outermost end of the end of the inner-rail connecting member. The clamping block 203 moves to the side of the inner-rail connecting member protruding from the inner-rail connecting member and is clamped with the inner wall groove 21 of the track 2. The operation is simple and the installation efficiency is improved.

[0051] In some embodiments, the conductive mechanism 40 is a conductive spring sheet, which is arranged on the top surface of the in-rail connecting block 10 and is respectively close to the clamping blocks 203; the in-rail connecting block 10 is fixed in the rail 2 through the clamping blocks 203; the device connecting member 30 is arranged at the bottom of the in-rail connecting block 10 and is used to be fixedly connected to the electrical device and form an electrical connection, one end of the conductive spring sheet is electrically connected to the device connecting member 30 and the other end is electrically connected to the conductive bar 22 in the rail 2.

[0052] The conductive spring sheet is a metal spring sheet, such as a copper sheet. A conductive strip 22 is provided in the track 2. When the track-in-track connection block 10 is placed in the track 2, the conductive spring sheet is electrically connected to the conductive strip 22. The clamping block 203 is a protrusion protruding from the side of the track-in-track connection block 10. The clamping block 203 can be fixed to the side of the track-in-track connection block 10 and installed so that it can slide in from one end of the track 2, or the track 2 is provided with a certain elasticity, which can achieve clamping. The clamping block 203 can also be configured to be telescopic inside and outside the track-in-track connection block 10. The specific structure can refer to patent CN114976796A. The clamping block 203 is driven by a sliding member to form a clamping structure that is easy to disassemble.

[0053] Since the in-rail connecting block 10 has a certain length, the said clamping blocks 203 are provided in plurality, and the said clamping blocks 203 are evenly distributed to the two ends of the said in-rail connecting block 10. By clamping the clamping blocks 203 at the two ends into the rail 2, the in-rail connecting block 10 is stably placed in the rail 2. Correspondingly, there are two said conductive springs, and the two said conductive springs can be close to the clamping blocks 203 at the same end. In order to improve the structural stability and optimize the internal space of the in-rail connecting block 10, the two said conductive springs can be close to the two said clamping blocks 203 at the two ends respectively. Preferably, in the direction perpendicular to the length of the rail 2, the two said conductive springs are respectively in the same plane with the two said clamping blocks 203 at the two ends. There is no torque between the said conductive springs and the clamping blocks 203, which can minimize the bending of the in-rail connecting piece between the two, thereby ensuring the stable electrical connection between the conductive springs and the conductive strip 22 in the rail 2.

[0054] In this embodiment, the clamping blocks 203 are respectively arranged on the side surfaces of the two ends of the in-rail connecting block 10, and the conductive springs are arranged on the top surface of the in-rail connecting block 10 and are respectively close to the clamping blocks 203, so as to reduce the torque between the conductive springs on the in-rail connecting block 10 and the clamping blocks 203, reduce the influence of the bending of the in-rail connecting block 10 itself on the connection between the conductive springs and the conductive strips 22 in the track 2 during long-term use, avoid poor contact between the conductive springs and the conductive strips 22 in the track 2, and improve the stability of the electrical connection.

[0055] In some embodiments, damping can be added to other parts of the in-rail connection block 10 to adjust the angle of an electrical device with a larger mass. Specifically, the in-rail connection block 10 includes a lower body and an upper cover body. The lower bottom surface of the upper cover body is provided with a damping part. The damping part can be made of a material such as rubber or silicone with a certain thickness. When the upper cover body covers the lower body, the damping part generates damping on the top of the device connector 30. The principle is that the top of the device connector 30 squeezes the damping part, and the elastic restoring force and surface friction of the damping part itself can bring resistance to the device connector 30. When a sufficiently large external force is not applied to the device connector 30, the resistance can prevent the device connector 30 from rotating. By configuring a damping part with a larger thickness, greater elasticity, and a larger surface friction coefficient, the angle adjustment of an electrical device with a larger mass can be achieved.

[0056] Furthermore, the lower bottom surface of the upper cover body is provided with reinforcing ribs, and the damping part is arranged at the lower edge of the reinforcing ribs. The reinforcing ribs can increase the structural strength of the inner rail connection block 10, and by arranging the damping part at the lower edge of the reinforcing ribs, the thickness of the damping part can be reduced while ensuring the same damping, thereby reducing costs.

[0057] In certain embodiments, the conductive mechanism 40 includes a conductive screw 401, a conductive nut 402, a first electrical connector 403, and a second electrical connector 404. The conductive screw 401, the conductive nut 402, the first electrical connector 403, and the second electrical connector 404 can all be made of metal conductive materials, such as iron, copper, etc. The in-rail connecting block 10 is used to connect to an electrical device, that is, the electrical device can be first fixedly connected and electrically connected to the in-rail connecting block 10, and the in-rail connecting block 10 is then snap-fitted and electrically connected to the track 2 that plays a fixing role, so that the electrical device is fixed under the track 2 and obtains power. The in-rail connecting block 10 is provided with a first electrical connector 403 and a first connecting hole 102, and the side of the electrical device connected to the in-rail connecting block 10 is provided with a second connecting hole 601, see Figure 7 For example, the second connection hole 601 is set on the top surface of the display screen. The conductive screw 401 passes through the first connection hole 102 and the second connection hole 601 in sequence, and then is threadedly connected and tightened with the conductive nut 402; one end of the first electrical connector 403 is set between the head of the conductive screw 401 and the first connection hole 102, and the other end is used to be electrically connected to an external power supply device, and the external power supply device refers to a track 2 with a conductive strip 22, a power adapter, and other devices that can provide power. One end of the second electrical connector 404 is set between the conductive nut 402 and the second connection hole 601, and the other end is used to be electrically connected to an electrical device. It should be noted that the structure of the first electrical connector 403 and the second electrical connector 404 can be a conductive wire or a conductive spring. When the conductive wire is selected, the conductive wire can be wrapped around the screw and fixed by tightening the screw nut. When the conductive spring is selected, a notch or hole for the screw to pass through can be set at one end of the conductive spring, and fixed by tightening the screw nut.

[0058] The power-consuming device may be a speaker, a display screen, or a lamp, and the power supply device may be a battery, a wire, or a conductive strip 22 in the track 2. This embodiment is described by assuming that the power-consuming device is a display screen and the power supply device is a power supply track 2.

[0059] The in-rail connecting block 10 is used to be connected with the rail 2. The in-rail connecting block 10 and the rail 2 can be connected for fixing only, and then powered by an external power supply through wires, or electrically connected while being fixed. Specifically, a conductive bar 22 can be set in the rail 2, and the first electrical connector 403 can be set in the in-rail connecting block 10. One end of the first electrical connector 403 used for electrical connection to an external power supply device extends out of the in-rail connecting block 10, and the two are configured so that when the in-rail connecting block 10 is connected to the rail 2, the first electrical connector 403 contacts the conductive bar 22 to form an electrical connection.

[0060] The first electrical connector 403 preferably adopts a conductive spring sheet, one end of the first electrical connector 403 is a sheet-shaped portion, and an opening not smaller than the first connecting hole 102 is opened in the sheet-shaped portion. During assembly, one end of the first electrical connector 403 is arranged above the first connecting hole 102, and the tail of the conductive screw 401 is passed through the opening at one end of the first electrical connector 403, inserted into the first connecting hole 102, and then threaded and tightened. At this time, the screw head of the conductive screw 401 can press one end of the first electrical connector 403 tightly to maintain a stable electrical connection, and the other end of the first electrical connector 403 can extend to the upper outer side or the front and rear outer sides of the connecting block 10 in the rail and be electrically connected to the conductive strip 22 in the rail 2, thereby completing the process of taking electricity from the conductive strip 22 of the rail 2, the first electrical connector 403, and the conductive screw 401 in sequence; the conductive screw 401 passes through the first connecting hole 1 02, continue to insert it into the second connecting hole 601. The second electrical connector 404 can use the same conductive spring sheet (i.e. a sheet-like portion with an opening at one end) as the aforementioned first electrical connector 403 and be arranged below the second connecting hole 601, while the conductive nut 402 is arranged below one end of the second electrical connector 404. After the conductive screw 401 passes through the second connecting hole 601 and one end of the second electrical connector 404 in turn and is threadedly connected and tightened with the conductive nut 402, the conductive nut 402 can press one end of the second electrical connector 404 to maintain a stable electrical connection. The other end of the second electrical connector 404 can extend to the interior of the electrical device and be electrically connected to the conductive end. The conductive end is used to access the power supply and can be arranged on the circuit board. At this point, the process of drawing power from the conductive screw 401, the second electrical connector 404, and the electrical device in sequence is completed. Combined with the above, a structure of fixed and power-drawing integrated connection can be formed.

[0061] In this embodiment, an in-rail connecting block 10 is used to engage with the rail 2 and obtain power supply. A first connecting hole 102 and a first electrical connector 403 are provided in the in-rail connecting block 10, and a second connecting hole 601 and a second electrical connector 404 are provided on the electrical device. A conductive screw 401 is passed through the first connecting hole 102 and the second connecting hole 601 in sequence to be threadedly connected and tightened with a conductive nut 402, and the first electrical connector 403 and the second electrical connector 404 are respectively fixed in the in-rail connecting block 10 and the electrical device accordingly. The cooperation of the conductive screw 401 and the conductive nut 402 realizes the fixing of the in-rail connecting block 10 and the electrical device and draws power, forming a fixed integrated power-drawing connection structure, without the need to additionally set up a power-drawing terminal of the in-rail connecting block 10 and a power-drawing port of the electrical device, effectively saving product costs.

[0062] Furthermore, the second electrical connector 404 is a U-shaped conductive wire, the bottom of the U-shaped conductive wire is passed around one end of the conductive screw 401 and fixedly connected, and one end of the top of the U-shaped conductive wire is electrically connected to the power supply end of the electrical device. The U-shaped conductive wire can be made of metal conductive materials, such as iron wire and copper wire. The circuit board is a PCB circuit board, and a conductive end is provided on the circuit board. The conductive end can be an existing structure for the circuit board to conduct electricity, such as conductive copper foil, socket, pin, etc. The electrical connector is a metal contact / spring or a conductive screw 401 / nut made of 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 draws power from the external power supply through the U-shaped conductive wire and the electrical connector to realize power supply. The circuit board is arranged inside the shell of the electrical device. It should be noted that the electrical device includes but is not limited to screens, speakers, lights and other equipment, and its shell can refer to the existing conventional structure of the corresponding equipment. The bottom of the U-shaped conductive wire goes around 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 fixed by 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, so that the structural design of the circuit board and the position setting of the conductive end are more flexible. The other end of the electrical connector is electrically connected to an external power source. The external power source can be the power supply of track 2. For example, in the patent publication number CN114976796A, a conductive strip 22 is set inside the track, the electrical connector is electrically connected to the track 2 connection block, and the track 2 connection block is electrically connected to the conductive strip 22 inside the track 2, so that the circuit board obtains power supply through the U-shaped conductive wire, the electrical connector, the track 2 connection block, and the conductive strip 22 in turn. The U-shaped conductive wire and the conductive end of the circuit board can be electrically connected by welding, or can be electrically connected by a jack, or by a spiral connection.

[0063] In this embodiment, a U-shaped conductive wire and an electrical connector are provided, the bottom of the U-shaped conductive wire is passed around one end of the electrical connector and fixedly electrically connected, and 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, and finally the other end of the electrical connector is electrically connected to an external power source to form an electrical connection structure of the electrical connector, the U-shaped conductive wire, and the circuit board. This structure can draw power stably, does not require the provision of power terminals and power ports, and reduces the production cost of the electrical device.

[0064] Furthermore, a receiving groove 602 is included. The receiving groove 602 is arranged below the second connecting hole 601 . The receiving groove 602 is used to receive and limit the conductive nut 402 . The front side of the receiving groove 602 is open, and the conductive nut 402 can be inserted into the receiving groove 602. Preferably, the conductive nut 402 has at least one side plane, and the internal space of the receiving groove 602 is adapted to the conductive nut 402. After the conductive nut 402 is inserted into the receiving groove 602 from the front opening, its side plane is in contact with the left, right or rear inner wall of the receiving groove 602. If only one side plane is in contact with one inner wall surface of the receiving groove 602, when the conductive screw 401 and the conductive nut 402 are relatively rotated and threadedly connected, it is only necessary to give the conductive nut 402 a resistance (for example, pressing it with a finger) at the front side opening of the receiving groove 602 to screw the conductive screw 401 into the conductive nut 402. If two side planes are in contact with the two inner wall surfaces of the receiving groove 602, the conductive screw 401 can be screwed into the conductive nut 402 without the aid of external force, which is easy and labor-saving, and improves assembly efficiency. On the other hand, the receiving groove 602 can also be used to pre-install the second electrical connector 404. It is only necessary to make the second electrical connector 404 into a structure that matches the receiving groove 602, for example, the width of the second electrical connector 404 is the same as or slightly smaller than the internal width of the receiving groove 602, and then the second electrical connector 404 and the conductive nut 402 can be pre-installed into the receiving groove 602, and then the conductive screw 401 is screwed into the conductive nut 402, thereby improving assembly efficiency. Preferably, the conductive nut is a square nut, which is limited by the square nut cooperating with the inner plane of the receiving groove, and only the conductive screw needs to be rotated to perform threaded connection, thereby improving assembly efficiency.

[0065] In some embodiments, the device connector 30 is rotatably connected to the in-rail connection block 10, and the rotatable connection method includes hinge, gear meshing connection, etc. Considering the manufacturing cost, a pair of circular grooves can also be provided in the in-rail connection block 10, and the two ends of the device connector 30 are configured as cylinders and are respectively placed in the circular grooves. By limiting the top of the device connector 30, the device connector 30 can be rotated relative to the in-rail connection block 10 through the relative movement of the cylinders at both ends and the circular grooves, and the line between the centers of the pair of circular grooves is collinear with the rotation axis of the device connector 30. Furthermore, in order to utilize the structure of the electrical connector to provide damping, on the one hand, the device connector 30 can be adjusted in angle in some usage scenarios, and on the other hand, the cost will not be increased too much, the conductive spring includes a first spring 405 and a second spring 406; the first spring 405 is fixed in the track connection block 10, and one end is electrically connected to the conductive strip 22 in the track 2; the second spring 406 is fixed to the end of the rotating shaft of the device connector 30, and one end of the second spring 406 is electrically connected to the electrical device; the other end of the first spring 405 and the other end of the second spring 406 apply elastic force to each other to form damping. Fig.10 , the other end of the first spring piece 405 is a V / U-shaped spring piece, and the other end of the second spring piece 406 is a columnar protrusion. After the device connection block is pressed into the rail connection block 10, the second spring piece 406 squeezes the end of the first spring piece 405 outward, so that the first spring piece 405 obtains elastic potential energy, and then the first spring piece 405 generates an elastic force on the second spring piece 406, and the elastic force can play a certain damping role. The interaction force between the first spring piece 405 and the second spring piece 406 can make the device connector 30 maintain its position after rotation. It should be noted that through this structure The damping size obtained by the structure can be proportional to the elastic force between the first spring piece 405 and the second spring piece 406. In actual use, the damping size can be set within a reasonable range. For example, when the device connection block is connected to a lighter speaker or lamp, after the angle is rotated, the gravity caused by the mass of the speaker or lamp itself is less than the resistance between the first spring piece 405 and the second spring piece 406, so the angle can be maintained; when the device connection block is connected to a heavier information sign 3, after the angle is rotated, the gravity caused by the mass of the information sign 3 itself is greater than the resistance between the first spring piece 405 and the second spring piece 406, so it can automatically return to a vertical state.
