Description

Technical Field

[0001] This utility model belongs to the field of lighting equipment technology, specifically a pendant lamp holder. Background Technology

[0002] Light bulbs are typically mounted and connected to power via a lamp holder. Specifically, power is supplied through terminals within the lamp holder that connect the live wire to the live wire connector and the neutral wire to the neutral wire connector. The terminals are installed between the partition and the lamp holder chip. Currently, the partition is fixed to the chip with screws, but finished products require screws to be tightened before assembly. This assembly process is time-consuming and impacts production efficiency.

[0003] When wires are inserted from the outside through the wire hole into the lamp holder housing and installed to the terminal block, the wires are not properly stored and secured. This is especially true for pendant lights, which can cause the lamp holder to wobble, resulting in friction between the wires and the lamp holder. Over time, this can damage the insulation layer of the wires and affect electrical safety.

[0004] Existing terminal blocks use a bolt-pressed wire structure, where the wire is pressed onto the connector plate by the end of the bolt. This method is prone to damaging the wires during wiring, especially when connecting multi-core wires, where the wires can easily be broken. Therefore, the drawbacks are quite obvious, and a solution is urgently needed. Utility Model Content

[0005] The purpose of this utility model is to provide a hanging lamp holder to solve problems such as low production efficiency of lamp holders, lack of internal wiring storage and fixation, easy damage to wiring, short service life, and impact on electrical safety.

[0006] This utility model provides a pendant lamp holder, including a partition, a neutral wire connecting piece, a terminal block, a live wire connecting piece, and a lamp holder core. The partition includes a mounting plate and a terminal receiving cavity located on one side of the mounting plate. The other side surface of the mounting plate is provided with a protrusion and a plug. The end face of the lamp holder core is provided with two sub-bases, a second notch corresponding to the protrusion, a neutral wire connecting piece through-hole for the neutral wire connecting piece to pass through, and a live wire connecting piece through-hole for the live wire connecting piece to pass through. The neutral wire connecting piece and the live wire connecting piece are respectively installed on the two sub-bases through the terminal block. The partition covers the end face of the lamp holder core, and the two sub-bases are located in the terminal receiving cavity, the plug is located in the neutral wire connecting piece through-hole, and the protrusion cooperates with the second notch.

[0007] A further solution: the plug abuts against the neutral wire connecting piece, the second notch communicates with the through hole of the live wire connecting piece, and while the protrusion engages with the second notch, one side of the protrusion abuts against the live wire connecting piece.

[0008] A further solution: the side of the mounting plate is provided with a first notch, and the end face of the lamp holder core is provided with a first locking block corresponding to the first notch.

[0009] A further embodiment: The terminal receiving cavity is divided into a live wire terminal receiving cavity and a neutral wire terminal receiving cavity. Both the live wire terminal receiving cavity and the neutral wire terminal receiving cavity are provided with through holes and screw holes. The through holes of the live wire terminal receiving cavity and the neutral wire terminal receiving cavity are located on opposite sides.

[0010] A further embodiment: The mounting plate is provided with two side plates distributed on both sides of the terminal receiving cavity, and the mounting plate is also provided with two clamping plates distributed on both sides of the terminal receiving cavity. The clamping plates are arranged parallel to the side plates, the clamping plates are located next to the through holes, and the clamping plates are provided with wire clamping grooves.

[0011] A further embodiment: both ends of the terminal receiving cavity are provided with a first engaging groove, and the side of the terminal seat that is far apart from each other is provided with a third engaging block corresponding to the first engaging groove.

[0012] A further solution: The mounting plate is also provided with two limiting holes, and the end face of the lamp holder core is provided with a second locking block corresponding to the two limiting holes respectively.

[0013] A further embodiment: The lamp holder core includes an outer shell with open ends, and a core tube is fixedly connected inside the outer shell. The core tube has a closed structure at one end, and the neutral wire connection plate through hole and the live wire connection plate through hole are located on the end face of the core tube.

[0014] A further solution: The inner wall of the core cylinder is provided with a neutral wire connection piece mounting groove, which is located next to the neutral wire connection piece through hole.

[0015] A further solution: A wire-passing hole is provided on one side of the terminal block, and a doorway is provided on the outside of the terminal block. The doorway is located on the side with the wire-passing hole. Two blocks are provided on the top of the side of the terminal block with the wire-passing hole. Neutral wire connecting piece has neutral wire protrusions on both sides of one end, and live wire connecting piece has live wire protrusions on both sides of one end.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. When connecting the partition plate to the lamp holder wick, the insert block is positioned inside the through hole of the neutral wire connecting piece, and the protrusion engages with the second notch to achieve a snap-fit ​​assembly between the partition plate and the lamp holder wick. During assembly, simply align the insert block with the through hole of the neutral wire connecting piece and the protrusion with the second notch, allowing the partition plate and the lamp holder wick to move towards each other to complete the insertion. Compared to using screws to fix the partition plate to the lamp holder wick, this eliminates the need for screw-tightening tools, making the operation more convenient, reducing the screw-tightening process, and improving production efficiency.

[0018] 2. The second notch is connected to the through hole of the live wire connecting piece. While the protrusion is engaged with the second notch, one side of the protrusion abuts against the live wire connecting piece, providing a limiting effect for each other. This can prevent the live wire connecting piece from moving and also prevent the protrusion from falling out. The insert is located in the through hole of the neutral wire connecting piece and also abuts against the neutral wire connecting piece, providing a limiting effect for each other. This can prevent the neutral wire connecting piece from moving and also prevent the insert from falling out, thus improving the stability of the assembly of the partition and the lamp holder core.

[0019] 3. By engaging the first locking block and the first notch, and engaging the second locking block and the limiting hole, the partition plate and the lamp holder core can be prevented from rotating relative to each other, thus preventing damage to the connecting piece and the wire.

[0020] 4. The wire passes through the wire clamping groove before entering the terminal block, so that the suspension point of the wire under gravity is far away from the wire stripped conductive part, preventing the stripped conductive part from being easily pulled apart by gravity due to the lack of insulation layer protection.

[0037] Please see Figures 1-3 , Figure 7 As shown, this embodiment provides a pendant lamp holder, including a partition plate 2, a neutral wire connecting piece 3, a terminal block 5, a live wire connecting piece 6, and a lamp holder wick 7. The partition plate 2 includes a mounting plate 21 and a terminal receiving cavity 22 located on one side of the mounting plate 21. The other side surface of the mounting plate 21 is provided with a protrusion 212 and a plug 213. The end face of the lamp holder wick 7 is provided with two end seats 721, a second notch 728 corresponding to the protrusion 212, a neutral wire connecting piece through hole 724 for the neutral wire connecting piece 3 to pass through, and a live wire connecting piece through hole 725 for the live wire connecting piece 6 to pass through. The neutral wire connecting piece 3 and the live wire connecting piece 6 are respectively installed on the two end seats 721 through the terminal block 5. The partition plate 2 covers the end face of the lamp holder wick 7, and the two end seats 721 are located in the terminal receiving cavity 22, the plug 213 is located in the neutral wire connecting piece through hole 724, and the protrusion 212 cooperates with the second notch 728.

[0038] For example, please refer to Figure 4As shown, a screw hole 51 is provided on one side wall of the terminal block 5. The opposite sides connected to the side wall with the screw hole 51 are open structures, allowing the neutral wire connecting piece 3 or the live wire connecting piece 6 to pass through. A locking screw 4 is installed in the screw hole 51. The terminal receiving cavity 22 has a screw hole 223 corresponding to the screw hole 51. The locking screw 4 is screwed into the screw hole 51 through the screw hole 223. The partition 2 is connected to the lamp holder wick 7 to realize the limiting installation of the terminal block 5.

[0039] The system has two terminal blocks 721. One terminal block 721 houses a neutral wire connector 3 via a terminal block 5. The neutral wire connector 3 passes through the terminal block 5, with one end snapped into the terminal block 721 and the other end extending into the lamp holder wick 7. The stripped conductive portion of the neutral wire is also located within the terminal block 5, and this portion is on the side of the neutral wire connector 3 furthest from the locking screw 4. Tightening the locking screw 4 onto the terminal block 5 allows for linear movement of the terminal block 5, pressing the stripped conductive portion of the neutral wire between the inner wall of the terminal block 5 and the neutral wire connector 3, thus establishing an electrical connection between the neutral wire and the connector 3. Unscrewing the locking screw 4 disconnects the electrical connection between the neutral wire and the connector 3, allowing the neutral wire to be removed. Another terminal block 721 houses a live wire connector 6 installed via a terminal block 5. One end of the live wire connector 6 is snapped onto the terminal block 721, and the other end extends into the lamp holder wick 7. The same terminal block 5 can be used. By screwing in the locking screw 4 fitted to the terminal block 5, the terminal block 5 can move linearly, pressing the stripped conductive portion of the live wire between the inner wall of the terminal block 5 and the live wire connector 6, thus establishing an electrical connection between the live wire and the live wire connector 6. Unscrewing the locking screw 4 disconnects the electrical connection between the live wire and the live wire connector 6, allowing the live wire to be removed.

[0040] The insert 213 is located within the through hole 724 of the neutral wire connecting piece, and the protrusion 212 engages with the second notch 728 to achieve a snap-fit ​​assembly between the partition 2 and the lamp holder wick 7. During assembly, simply align the insert 213 with the through hole 724 of the neutral wire connecting piece and the protrusion 212 with the second notch 728, allowing the partition 2 and the lamp holder wick 7 to move towards each other to complete the insertion. Compared to using screws to fix the partition 2 to the lamp holder wick 7, this eliminates the need for screw-tightening tools, making operation more convenient, reducing the screw-tightening process, and improving production efficiency. This application adopts a terminal block 5 wire-pressing design, which, compared to a screw-pressing design, does not damage the wires during wiring, reduces maintenance costs, and provides stable and reliable contact retention force and good conductivity.

[0041] In some embodiments, please refer to Figure 3 , Figure 7 , Figure 9As shown, the insert 213 abuts against the neutral wire connecting piece 3, the second notch 728 communicates with the through hole 725 of the live wire connecting piece, and while the protrusion 212 engages with the second notch 728, one side of the protrusion 212 abuts against the live wire connecting piece 6. The protrusion 212 and the live wire connecting piece 6 provide mutual limiting functions, preventing both movement of the live wire connecting piece 6 and disengagement of the protrusion 212. Similarly, the insert 213 and the neutral wire connecting piece 3 provide mutual limiting functions, preventing both movement of the neutral wire connecting piece 3 and disengagement of the insert 213, thus improving the stability of the assembly between the partition 2 and the lamp holder wick 7. Compared to fixing the partition 2 and the lamp holder wick 7 with screws, this reduces production costs.

[0042] Further, please refer to Figure 2 , Figure 7 As shown, the side of the mounting plate 21 is also provided with a first notch 211, and the end face of the lamp holder core 7 is also provided with a first locking block 722 corresponding to the first notch 211. By cooperating with the first locking block 722 and the first notch 211, the partition plate 2 and the lamp holder core 7 can be prevented from rotating relative to each other, thus preventing damage to the connecting piece and the wire.

[0043] Further, please refer to Figure 1 , Figure 2 As shown, the terminal receiving cavity 22 is divided into a live wire terminal receiving cavity and a neutral wire terminal receiving cavity. Both the live wire terminal receiving cavity and the neutral wire terminal receiving cavity are provided with through holes 221 and screw holes 223. The terminal 5 is placed inside the terminal receiving cavity 22, with the open side of the terminal 5 corresponding to the through hole 221. The through hole 221 of the live wire terminal receiving cavity allows the live wire to be inserted, ensuring that the stripped conductive part of the live wire is located within the live wire terminal receiving cavity. The through hole 221 of the neutral wire terminal receiving cavity allows the neutral wire to be inserted, ensuring that the stripped conductive part of the neutral wire is located within the neutral wire terminal receiving cavity. The through holes 221 of the live wire terminal receiving cavity and the neutral wire terminal receiving cavity are located on opposite sides, structurally separating the wiring spaces for the live wire and the neutral wire. The through holes 221 for inserting the live wire and the neutral wire are located on different sides, greatly reducing the risk of short circuits.

[0044] In some embodiments, please refer to Figure 2As shown, the mounting plate 21 has two side plates 23 distributed on both sides of the terminal receiving cavity 22, and two retaining plates 24 distributed on both sides of the terminal receiving cavity 22. The retaining plates 24 are arranged parallel to the side plates 23, forming a wire passage channel 25 between the retaining plates 24 and the side plates 23. The retaining plates 24 are located next to the through holes 221 and have wire-holding grooves 241. The wire passes through the wire passage channel 25, bends through the wire-holding grooves 241, and then passes through the through holes 221 to be inserted into the terminal. This makes the suspension point of the wire under gravity far away from the wire stripped conductive position, preventing the stripped conductive position from being easily pulled and broken by gravity due to the lack of insulation layer protection. The wire passage channel 25 limits the wire, preventing the wire from shaking and wearing in the lamp holder, and preventing the power core from loosening and breaking, thus improving electrical safety. The wire passage channel 25 also changes the wire routing direction and increases the wire gathering function.

[0045] In some embodiments, please refer to Figure 2 , Figure 7 As shown, both ends of the terminal receiving cavity 22 are provided with first engaging grooves 222, and the terminal base 721 is provided with third engaging blocks 729 corresponding to the first engaging grooves 222 on the opposite sides. When the partition is connected to the lamp holder wick, the third engaging block 729 is located in the first engaging groove 222. Compared with the insertion block 213 being located in the neutral wire connecting piece through hole 724 and the protrusion 212 cooperating with the second notch 728, this adds a locking limit in another direction, further enhancing the stability and reliability of the assembly of the partition 2 and the lamp holder wick 7.

[0046] Furthermore, the mounting plate 21 is also provided with two limiting holes 26, and the end face of the lamp holder wick 7 is provided with a second locking block 723 corresponding to the two limiting holes 26 respectively. By aligning the positions of the second locking block 723 and the limiting holes 26, the mating position of the insert and the protrusion can be quickly and accurately positioned, avoiding the insert and the protrusion from being too close to the connecting piece and causing damage to the connecting piece during insertion.

[0047] In some embodiments, please refer to Figure 2 , Figure 7 As shown, the lamp holder wick 7 includes an outer shell 71 with open ends. A wick cylinder 72 is fixedly connected inside the outer shell 71. The wick cylinder 72 has a closed structure at one end. The neutral wire connecting piece through hole 724 and the live wire connecting piece through hole 725 are provided on the end face of the wick cylinder 72. The end of the outer shell 71 near the partition 2 is provided with an external thread 711 for screwing the lamp holder housing 1. The end of the lamp holder housing 1 away from the outer shell 71 is provided with a wire hole 11 for the wire to pass through. The other end of the lamp holder housing 1 is provided with a thread that mates with the external thread 711. The end of the wick cylinder 72 away from the partition 2 is provided with an internal thread 727 for screwing the bulb. It should be noted that the internal thread 727 of the wick cylinder 72 can also be replaced by a bayonet to install commercially available bayonet bulbs.

[0048] In some embodiments, please refer to Figure 7 , Figure 8 As shown, the inner wall of the core cylinder 72 is provided with a neutral wire connecting piece mounting groove 726. The neutral wire connecting piece mounting groove 726 is located next to the neutral wire connecting piece through hole 724. When the partition plate 2 is connected to the lamp holder core 7, the neutral wire connecting piece 3 passes through the neutral wire connecting piece mounting groove 726, and the end of the neutral wire connecting piece 3 extends out of the neutral wire connecting piece mounting groove 726. The plug 213 is located inside the neutral wire connecting piece mounting groove 726, so that the neutral wire connecting piece 3 and the plug 213 can better provide mutual limiting function. The bulb is usually fixedly connected to the lamp holder through the bulb head and realizes the power supply and disconnection. The top of the bulb head has metal contacts and the side has metal connecting parts. The bulb is installed in the core cylinder 72. The metal contacts at the top of the bulb head are in contact with the live wire connecting piece 6, and the metal connecting parts on the side of the bulb head are in contact with the neutral wire connecting piece 3.

[0049] In some embodiments, please refer to Figures 5-7 As shown, a wire-passing hole 7211 is provided on one side of the terminal block 721 for wires to pass through. The terminal 5 is installed on the terminal block 721, and the open side of the terminal 5 corresponds to the wire-passing hole 7211. A doorway 7214 is provided on the outside of the terminal block 7211, and the doorway 7214 is located on the side where the wire-passing hole 7211 is provided. Two blocks 7212 are provided on the top of the side of the terminal block 7211 where the wire-passing hole 7211 is provided. Neutral wire connecting piece 3 has neutral wire protrusions 31 on both sides of one end, and live wire connecting piece 6 has live wire protrusions 61 on both sides of one end. A second engaging groove 7213 is formed between the two stops 7212. The neutral wire connecting piece 3 passes through the second engaging groove 7213, and its end abuts against the top of the doorway 7214. The neutral wire connecting piece protrusions 31 on both sides cooperate with the stops 7212 on both sides to limit their movement. The end of the neutral wire connecting piece 3 is limited between the top of the doorway 7214 and the top wall of the through hole 221. The neutral wire connecting piece 3 is installed with multi-directional limiting to prevent it from shifting and coming off. Referring to the assembly method of the neutral wire connecting piece 3, the live wire connecting piece 6 is also installed with multi-directional limiting to prevent it from shifting and coming off. However, the live wire connecting piece 6 and the neutral wire connecting piece 3 are installed in different terminal blocks 721.

[0050] Furthermore, the portion of the neutral wire connecting piece 3 and the live wire connecting piece 6 located within the terminal 5 is also provided with a folding part 32. The folding part 32 is located on the side near the locking screw 4. The folding part 32 is elastic and can prevent the locking screw 4 from squeezing and deforming the wire pressing side of the neutral wire connecting piece 3 and the live wire connecting piece 6, thus avoiding unreliable wire pressing.

[0051] It should be noted that the neutral wire connecting piece 3, the locking screw 4, the terminal block 5, and the live wire connecting piece 6 are made of conductive material, while the lamp holder shell 1, the partition plate 2, and the lamp holder core 7 are made of insulating material.

[0052] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
