[0002] In shopping malls and supermarkets, electronic screens are used to display or update the prices of goods on the shelves in real time, so as to facilitate consumers to understand the prices of goods on the shelves. However, the use of electronic screens is also accompanied by the arrangement of a large number of power cords for connection, resulting in a large number of power cords being messy and prone to risks such as mutual entanglement and short circuit of the power cords. Therefore, tracks are often installed on the shelves to solve such problems.

[0003] In the prior art, for example, the Chinese patent with the publication number CN208028337U provides a connection terminal, a track and a system. By rotating the rotary knob of the connection terminal and clamping it in the knob chute, the signal line on the connection terminal is connected to the signal interface of the device through the signal connector. When the PCB board is powered on, electric energy will be transmitted to the device through the metal elastic sheet and the terminal body. In order to quickly install the device body, hooks are installed on the track. The hooks can slide in the knob chute of the track through the sliding connector, and the device body is suspended on the hook through the through hole on the back. However, the way of suspending the device body on the hook also has problems of unstable installation and occupying the track space. Summary of the Utility Model

[0048] Please refer to Figures 1-9, an embodiment of the present utility model provides a conductive block 1, which includes a conductive track 11 and a power-taking head 12. A chute 111 is provided on one side of the conductive track 11 for accommodating the power-taking head 12. The power-taking head 12 is used for fixedly connecting an external component and electrically connecting with an electrical device. Two conductive strips 113 connected to a power supply circuit are provided in the chute 111. When the power-taking head 12 is slidably clamped in the chute 111 through the cross-section of the conductive track 11, the power-taking head 12 is electrically connected to the two conductive strips 113. The above can achieve the effect of firmly connecting the external component, and compared with multiple components being commonly connected to the conductive track 11, only the power-taking head 12 occupies the track space here, that is, it has the effect of reducing the occupied track space.

[0049] In some embodiments, the two conductive strips 113 are arranged at a position in the chute 111 close to the other side of the conductive track 11. This facilitates the electrical connection between the power-taking head 12 and the conductive strips 113, and also facilitates the installation of the power-taking head 12 in the chute 111. That is, if the conductive strips 113 are arranged on both sides of the chute 111, it is not conducive to the power-taking head 12 being slidably clamped in the chute 111 through the cross-section of the conductive track 11.

[0050] In some embodiments, it further includes an inner plate 114. The inner plate 114 is arranged at a position in the chute 111 close to the other side of the conductive track 11 for embedding the two conductive strips 113. This facilitates installation, that is, directly embedding the conductive strips 113 onto the inner plate 114 and then installing the inner plate 114 into the chute 111, instead of embedding the conductive strips 113 into the chute 111. During maintenance, only the inner plate 114 needs to be removed from the chute 111.

[0051] Preferably, it further includes an inner plate 114 for embedding the two conductive strips 113. The chute 111 further includes two third protrusions 1113 respectively arranged on the two side walls of the chute 111 for clamping the inner plate 114 at a position in the chute 111 close to the other side of the conductive track 11, making the inner plate 114 more stable. It is also convenient for installation, that is, directly embedding the conductive strips 113 onto the inner plate 114 and then installing the inner plate 114 into the chute 111, instead of embedding the conductive strips 113 into the chute 111. During maintenance, only the inner plate 114 needs to be removed from the chute 111. It is also easy to set the space occupied by the third protrusions 1113 on the side wall of the chute 111 to be adapted to the two elastic conductive sheets 121, so that when installing the power-taking head 12, it is convenient for the two elastic conductive sheets 121 to elastically contact the conductive strips 113 on the inner plate 114 to generate an electrical connection, that is, there will be no poor contact and no situation where installation is impossible.

[0052] In some embodiments, the power-taking head 12 includes two elastic conductive sheets 121, a power-taking core 122, two wires 124, and a connecting member 123. The power-taking core 122 is disposed in the chute 111, and the elastic conductive sheets 121 are disposed on one side of the power-taking core 122 facing the conductive strip 113. The wires 124 are disposed on the power-taking core 122. One end of each wire 124 is electrically connected to the elastic conductive sheet 121, and the other end of the wire 124 extends outside the power-taking core 122 and is used for electrically connecting to an electrical device. The connecting member 123 is disposed at a position of the power-taking core 122 facing the opening of the chute 111 and is used for connecting an external component. During installation, the two elastic conductive sheets 121 are in elastic contact with the two conductive strips 113 to form an electrical connection.

[0053] In some embodiments, the chute 111 includes two first protrusions 1111 symmetrically disposed at positions near the opening on both side walls of the chute 111. The connecting member 123 has a hollow structure 1231 for embedding the power-taking core 122. During installation, the power-taking core 122 restricts the sliding of the connecting member 123 alone in the chute 111, and the first protrusions 1111 and the power-taking core 122 clamp the connecting member 123 between the opening of the chute 111 and the power-taking core 122. Such a setting makes the connecting member 123 and the power-taking core 122 form an integral body and are jointly clamped at the same position in the chute 111.

[0054] In some embodiments, the connecting member 123 further includes a plurality of through holes 1232. The through holes 1232 are dispersedly disposed on both sides of the hollow structure 1231 along the direction of the chute 111, and the through holes 1232 are used for connecting to other external components. Preferably, the through holes 1232 can be bolted to external components that also have a through hole structure.

[0055] Preferably, the through holes 1232 have a threaded structure, and they will be more stable when bolted to external components that also have a through hole structure.

[0056] Preferably, there are two of the plurality of through holes 1232, which are dispersedly disposed on both sides of the hollow structure 1231 along the direction of the chute 111, so as to save materials.

[0057] In some embodiments, the chute 111 further includes two second protrusions 1112 respectively disposed on both side walls of the chute 111. The power-taking core 122 includes two core protrusions 125 respectively disposed on both sides of the power-taking core 122 facing the chute 111. During installation, the two second protrusions 1112 clamp the power-taking core 122 in the chute 111 through the two core protrusions 125.

[0058] In some embodiments, on the other side of the conductive rail 11 is an installation part 112, and the installation part 112 has an installation groove 1121 for installing the conductive rail 11 on an external shelf.

[0059] Preferably, the installation groove 1121 has two groove protrusions 11212 symmetrically arranged at the notch of the installation groove 1121, such that the notch width is smaller than the inner width of the groove; alternatively, optionally, the shape of the installation groove 1121 is a C-shaped arc, and the notch width is smaller than the diameter of the circle; in both of the above structures of the installation groove 1121, the notch width is smaller than the inner width of the groove, which is convenient for an external shelf. For example, during installation, when the crossbar on the shelf passes through the cross-section of the conductive rail 11 and slides into the installation groove 1121, stable installation can be achieved; or the shelf has a connecting block, the length of the connecting block is between the notch width and the inner width of the groove, the width of the connecting block is smaller than the notch width, and the thickness of the connecting block is smaller than the depth of the notch. During installation, the connecting block can extend into the interior of the installation groove 1121, and then by rotating a certain angle (such as 90°), it can be clamped inside the installation groove 1121 to achieve the external connection of the conductive rail 11 to the shelf.

[0060] Preferably, the conductive rail 11 further includes installation holes 1122 that run along and through the conductive rail 11 for external connection to a shelf; for example, during installation, when the crossbar on the shelf passes through the cross-section of the conductive rail 11 and penetrates the installation holes 1122, stable installation can be achieved. Preferably, the number of installation holes 1122 is more than one and they are dispersedly arranged on both sides of the installation groove 1121, so that the force is more evenly distributed when externally connecting to the shelf. Preferably, the number of installation holes 1122 is two, which are respectively arranged on both sides of the installation groove 1121, so that while the force is evenly distributed when externally connecting to the shelf, materials can also be saved.

[0061] In some embodiments, a conductive fixing structure 2 uses the conductive block 1 as described in any one of the above, and the conductive fixing structure 2 is arranged in the outlet direction of the chute 111; the conductive fixing structure 2 includes a connecting plate 21 and a vertical rod 22. The connecting plate 21 is arranged on the upper part of the vertical rod 22 and is fixedly connected to the connecting member 123 and the vertical rod 22 respectively; the vertical rod 22 is used for fixedly connecting to an electrical device.

[0062] Preferably, the vertical rod 22 has a hollow structure, defined as the rod hollow structure 221. On one side of the vertical rod 22, a plurality of screw holes 222 are provided and communicate with the rod hollow structure 221. Such a setting is used for fixedly connecting with an electrical device. For example, if the electrical device has a connecting rod that matches the rod hollow structure 221, the connecting rod is inserted into the rod hollow structure 221, and then bolts can be screwed through the screw holes 222 to achieve the fixed connection between the vertical rod 22 and the electrical device. Preferably, the number of screw holes 222 is two, and they are dispersedly arranged on one side of the vertical rod 22.

[0063] Preferably, the vertical rod 22 has a rod hollow structure 221. On both sides of the vertical rod 22, a plurality of screw holes 222 are symmetrically provided. When the electrical device has a through hole that matches the rod hollow structure 221 and also has a plurality of corresponding screw holes 222, the connecting rod is inserted into the rod hollow structure 221, and bolts can be passed through the screw holes 222 and the through holes to clamp the connecting rod, thereby achieving the fixed connection between the vertical rod 22 and the electrical device. Preferably, the number of screw holes 222 is one.

[0064] Preferably, the connecting plate 21 has a plurality of plate through holes 212, and the plate through holes 212 are arranged in one-to-one correspondence with the part through holes 1232. During installation, bolts pass through the plate through holes 212 and the part through holes 1232 to tightly connect the connecting plate 21 and the connecting part 123 together. Preferably, the number of the plate through holes 212 is two, which is convenient for saving materials.

[0065] Preferably, the connecting plate 21 has a hollow structure, defined as the plate hollow structure 211. The plate hollow structure 211 correspondingly communicates with the part hollow structure 1231 and the rod hollow structure 221. Such a setting is used for when the conductive block 1 is electrically connected to the electrical device, the circuit (such as: wire 124) can be directly arranged through the internal hollow structure without being exposed outside, which is safer and more beautiful.
