Description

Technical Field

[0001] This utility model belongs to the field of lighting power supply technology, specifically relating to a power supply device and power supply system. Background Technology

[0002] Existing lighting fixtures installed on cabinets and shelves typically come with long power cords to ensure they can connect to a power source. This results in a messy, unsightly tangled arrangement of excessively long cords after installation, posing a safety hazard. Furthermore, the installation process requires manual stripping and soldering of the wires, which is inconvenient. Utility Model Content

[0003] The first technical problem to be solved by this utility model is to provide a power-generating device that is convenient for power extraction while also allowing for adjustment of the wire length and preventing the wire from being too long, in light of the current state of the technology.

[0004] The second technical problem to be solved by this utility model is to provide a power extraction system having the above-mentioned power extraction device.

[0005] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a power-generating device, characterized in that it includes:

[0006] An insulating base plate has a strip-shaped main wire groove with open ends on its first plate surface for the main wire connected to the power supply to pass through it; at the same time, a branch wire groove for branch wires to be inserted is also provided on the first plate surface next to the main wire groove.

[0007] An insulating cover is detachably mounted on the first plate of the insulating base plate to cover the main cable tray and the branch cable tray.

[0008] The conductive strip has a first piercing element and a second piercing element at both ends, which are respectively located in the main wire groove and the branch wire groove. Under the action of the insulating cover, the first piercing element and the second piercing element are arranged to pierce the outer insulation layer of the main wire in the corresponding main wire groove and the outer insulation layer of the branch wire in the branch wire groove, so that the main wire and the branch wire are electrically connected.

[0009] During installation, the main wire groove on the insulating base plate is assembled to the main wire, and the branch wire groove on the insulating base plate is assembled to the branch wire connected to the lamp. Then, the insulating cover is placed on the insulating base plate. This allows the first piercing piece on the conductive strip to pierce the outer insulation of the main wire in the main wire groove and contact the metal part inside the main wire. The second piercing piece on the conductive strip pierces the outer insulation of the branch wire in the branch wire groove and contacts the metal part inside the branch wire. Thus, the conductive strip electrically connects the main wire and the branch wire to achieve power extraction. During this process, the branch wire can be cut to an appropriate length according to the distance between the lamp and the power extraction device to avoid the wire being too long. The cut branch wire is then inserted into the branch wire groove on the insulating base plate, and the insulating base plate is closed to achieve power extraction, eliminating the need for wire stripping and soldering, and simplifying operation. When multiple lamps need to be powered simultaneously, multiple power extraction devices described above can be used and sequentially installed on the same main wire. The branch wires connected to each lamp are connected to the branch wire groove of their respective power extraction devices.

[0010] Preferably, the extension direction of the main cable trough is perpendicular to the extension direction of the branch cable trough. The vertically arranged main cable trough and branch cable trough facilitate the assembly of the main conductor and branch conductor, and the assembled branch conductor is perpendicular to the main conductor, resulting in a reasonable positional distribution.

[0011] Preferably, the branching trough has a first end relatively close to the main branching trough and a second end relatively far from the main branching trough. The first end is closed and the second end is open, so that the end of the branching wire can be inserted into the branching trough. That is, after the branching wire is cut to the required length, the end of the branching wire is inserted into the branching trough and then covered with an insulating cover.

[0012] In the above scheme, preferably, the first surface of the insulating base plate faces upward, and both the first piercing member and the second piercing member have piercing needles with the top pointed upward and the bottom integrated with the conductive strip.

[0013] Furthermore, the first and second piercing components also have blades with a cutting edge at the top and an integral connection between the bottom and a conductive strip, with the cutting edge facing upwards to accommodate the corresponding wire. The combination of the blade and the piercing needle improves the success rate of power extraction.

[0014] To further improve the success rate of puncture and power extraction, preferably, there are at least two puncture needles located in the main wire groove and arranged at intervals along the extension direction of the main wire groove; there are also at least two blades located in the main wire groove and located on both sides of each puncture needle along the extension direction of the main wire groove.

[0015] Furthermore, the two piercing needles located within the main cable groove are positioned on either side of the central axis of the main cable groove; the cutting edges of the two blades located within the main cable groove are located on the central axis of the main cable groove. When the conductor is centrally positioned (on the central axis of the main cable groove), the piercing device of this invention has a high success rate in piercing and extracting electricity; when the conductor is not completely on the central axis of the main cable groove, the positional design of the piercing needles and blades in this invention can improve the success rate of piercing and extracting electricity.

[0016] Preferably, the main cable tray and / or branch cable tray have two oppositely arranged sidewalls, and each sidewall is provided with a protrusion to center and limit the corresponding wires between the two protrusions, so that the wires can be centrally arranged in the corresponding cable tray.

[0017] Preferably, the conductive strip is disposed on the second surface of the insulating base plate, and the first and second piercing members at both ends of the conductive strip pass through the insulating base plate along the thickness direction and are located in their respective main wire grooves and branch wire grooves. During installation, the second surface of the conductive strip can be attached to the mounting surface of cabinets, shelves, etc., to avoid the wire strip being exposed and improve safety during use.

[0018] Furthermore, the main cable tray, the branch cable tray, and the conductive strip are arranged as a group, and there are two groups, with the two main cable trays arranged side by side and the two branch cable trays arranged side by side.

[0019] In the above embodiments, preferably, the insulating cover includes two cover bodies, respectively corresponding to the main cable tray and the branch cable tray, and are connected to the insulating base plate by snaps and locking holes. The separate cover body design facilitates installation and maintenance.

[0020] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a power supply system having the power supply device as described above, characterized in that: there are at least two power supply devices, which are spaced apart along the length of the main conductor connecting the power supply, and each power supply device is connected to a lighting fixture through its own branch conductor.

[0021] Compared with existing technologies, the advantages of this utility model are as follows: Through the arrangement of the insulating base plate, insulating cover, and conductor strip, during installation, the main wire groove on the insulating base plate is assembled to the main conductor, and the branch wire groove on the insulating base plate is assembled to the branch conductor connected to the lamp. Then, the insulating cover is placed on the insulating base plate. This allows the first piercing element on the conductor strip to pierce the outer insulation layer of the main conductor in the main wire groove and contact the metal part inside the main conductor. Similarly, the second piercing element on the conductor strip pierces the outer insulation layer of the branch conductor in the branch wire groove and contacts the metal part inside the branch conductor. Thus, the conductor strip electrically connects the main conductor and the branch conductor to achieve power extraction. During this process, the branch conductor can be cut to a suitable length according to the distance between the lamp and the power extraction device, thus avoiding excessively long conductors. The cut branch conductor is then inserted into the branch wire groove of the insulating base plate, and the insulating base plate is closed to achieve power extraction, eliminating the need for wire stripping and soldering, and simplifying operation. When multiple lamps need to draw power simultaneously, multiple power-drawing devices as described above can be used and sequentially installed on the same main line. The branch wires connected to each lamp can be connected to the branch slots of their respective power-drawing devices. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] like Figures 1-7 As shown, this is a preferred embodiment of a power-generating device and power-generating system of the present invention. The power-generating device includes an insulating base plate 1, an insulating cover 2, and a conductive strip 3.

[0031] The insulating base plate 1 has a first plate surface and a second plate surface, with the first plate surface facing upwards and the second plate surface facing downwards. A strip-shaped main wire groove 11, open at both ends, is provided on the first plate surface, with the groove opening facing upwards, for the main power conductor 101 to pass through. A branch wire groove 12, with its opening facing upwards, is also provided on the first plate surface next to the main wire groove 11, for the insertion of branch wires 102. The extension direction of the branch wire groove 12 is perpendicular to the extension direction of the main wire groove 11, and the branch wire groove 12 has a first end 121 relatively close to the main wire groove 11 and a second end 122 relatively far away from the main wire groove 11. The first end 121 is closed, and the second end 122 is open, allowing the end of the branch wire 102 to be inserted into the branch wire groove 12. In this embodiment, both the main cable trough 11 and the branch cable trough 12 have two side walls arranged opposite to each other, and each side wall is provided with a vertically extending protrusion 14. The two opposite protrusions 14 form a group, and there are at least two groups arranged at intervals along the extension direction of the cable trough, so as to center and limit the corresponding wires between the two protrusions 14.

[0032] The insulating cover 2 is detachably mounted on the first surface of the insulating base plate 1 to cover the main cable tray 11 and the branch cable tray 12. In this embodiment, the insulating cover 2 includes two independent cover bodies 20, respectively corresponding to the main cable tray 11 and the branch cable tray 12, and are connected to the insulating base plate 1 by snap-fit ​​13 and snap-fit ​​holes 21. Each cover body 20 is connected to the insulating base plate 1 on one side by its own flexible connecting strip 22 to prevent the cover body 20 from detaching from the insulating base plate 1 and being lost. Furthermore, the design of the connecting strip 22 does not affect the snap-fit ​​connection and separation of the cover body 20 and the insulating base plate 1.

[0033] The aforementioned conductive strip 3 is horizontally disposed on the second surface of the insulating base plate 1, and the extension direction of the conductive strip 3 is consistent with the extension direction of the branching groove 12. One end of the conductive strip 3 is bent upward to form a first piercing element 31, which passes through the insulating base plate 1 along the thickness direction and is located in the main wire groove 11. The other end of the conductive strip 3 is bent upward to form a second piercing element 32, which passes through the insulating base plate 1 along the thickness direction and is located in the branching groove 12. When the insulating cover 2 is placed on the first surface of the insulating base plate 1, the first piercing element 31 and the second piercing element 32 are arranged to pierce the outer insulation layer of the main wire 101 in the corresponding main wire groove 11 and the outer insulation layer of the branch wire 102 in the branching groove 12, thereby electrically connecting the main wire 101 and the branch wire 102. In this embodiment, both the first piercing element 31 and the second piercing element 32 have the following characteristics:

[0034] A piercing needle 33 with its top pointed upwards and its bottom integrated with the conductive strip 3;

[0035] And a blade 34 with a blade edge 340 at the top and a bottom integrated with a conductive strip 3, with the blade edge 340 facing upwards so that the corresponding wire can be placed therein.

[0036] Simultaneously, there are two piercing needles 33 located within the main wire groove 11, arranged at intervals along the extension direction of the main wire groove 11; there are also two blades 34 located within the main wire groove 11, positioned on both sides of the two piercing needles 33 along the extension direction of the main wire groove 11. Furthermore, the two piercing needles 33 located within the main wire groove 11 are positioned on both sides of the central axis 110 of the main wire groove 11; the cutting edges 340 of the two blades 34 located within the main wire groove 11 are located on the central axis 110 of the main wire groove 11.

[0037] There is one piercing needle 33 and one blade 34 located in the dividing groove 12. The piercing needle 33 and the blade 34 are arranged at intervals along the extension direction of the dividing groove 12 and are both located on the central axis of the dividing groove 12.

[0038] In this embodiment, two sets are formed by cooperating main wire grooves 11, branch wire grooves 12, and conductive strips 3. The two main wire grooves 11 are arranged side by side so that the two main main wires connecting the positive and negative terminals of the power supply can be passed through them respectively. The two branch wire grooves 12 are arranged side by side, and the two conductive strips 3 are arranged independently side by side.

[0039] like Figure 7 As shown, the power supply system includes at least two power supply devices, each of which is spaced apart along the length of the main power supply conductor 101. Each power supply device is connected to a lighting fixture via its own branch conductor 102.

[0040] In this embodiment, power is extracted by piercing the main wire and branch wires. The wires are inserted into the corresponding slots of the power extraction device without stripping the copper wires, and then covered with an insulating cover to achieve safe and stable circuit conduction. Furthermore, the branch wires connecting to the light fixtures can be shortened as needed and inserted into the corresponding slots of the power extraction device, resulting in neat wiring on the cabinet or shelf without excess wires. Power can be extracted from any position on the main wire, facilitating adjustment.

However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
