Description

Technical Field

[0001] This utility model belongs to the technical field of lamp connection structure, specifically relating to a convenient connection joint structure for lamp installation. Background Technology

[0002] LED lighting fixtures are a new type of light source that has emerged and developed rapidly in recent years. Its many advantages have led to its increasingly wide range of applications.

[0003] Some LED lighting fixtures, including the lamp body and lamp holder, are connected by wires, and their structure is non-removable. These LED lighting fixtures are packaged, transported, and sold as complete sets, which makes them inconvenient to transport and store, increasing transportation costs. Furthermore, when a part of the LED lighting fixture, such as the power supply or light source, needs repair or replacement, it often requires a cumbersome disassembly and reassembly process.

[0004] Some LED lighting fixtures include lamp holders, lamp arms, and lamp bodies. The connections between the lamp holders, lamp arms, and lamp bodies are generally secured by screws or welding. Assembly and disassembly require the use of tools to tighten each screw or the use of welding tools. Before assembly, terminal blocks or tape are needed to connect the power cord. Assembly and disassembly are labor-intensive and time-consuming, electrical connections are troublesome, production efficiency is low, and subsequent maintenance and replacement are troublesome.

[0005] To address the technical challenges of cumbersome installation, a power connection structure is typically used at the junction of the lamp holder, lamp arm, and lamp body for connection, fixation, and electrical connection. This power connection structure is generally designed as a male-female plug, as illustrated in patent application number 2024216917077, which describes a convenient docking and installation structure for chandeliers. In this structure, the limiting nut that mates with the female plug is connected to the limiting thread of the hanging rod via an external thread. That is, the limiting nut and hanging rod are fixed solely by the thread itself. During use, environmental vibrations may cause the threaded connection between the limiting nut and the hanging rod to gradually loosen, reducing the support force of the mounting point on the female plug. In severe cases, the limiting nut may fall off, causing the lamp to lose its mechanical fixation and creating a safety hazard. Utility Model Content

[0006] To address the issues in the existing male-female plug structure, where the limiting nut that mates with the female plug is connected to the limiting thread of the hanging rod via an external thread, the threaded connection between the limiting nut and the hanging rod may gradually loosen due to environmental vibrations during the use of the chandelier. This can lead to a decrease in the supporting force of the support on the female plug, and in severe cases, the limiting nut may fall off, causing the lamp to lose its mechanical fixation and creating safety hazards. This utility model provides a convenient connection joint structure for lamp installation.

[0007] The technical effects to be achieved by this utility model are realized through the following technical aspects: This utility model provides a convenient connection connector structure for lamp installation, including: a housing, a male plug assembly, a female plug, a locking member, and a locking member. The housing has a first assembly cavity, the male plug assembly is located in the upper part of the first assembly cavity, the locking member is located in the lower part of the first assembly cavity, and the locking member is locked to the housing to lock the male plug assembly and the locking member in the first assembly cavity. The female plug is inserted into the first assembly cavity from the bottom of the housing to engage with the locking member, and the female plug is inserted into the male plug assembly.

[0008] In some alternative implementations, the male connector assembly includes a male connector, a male socket, and a spring. The male socket has a second assembly cavity, the male connector is disposed within the second assembly cavity, and the spring is sleeved on the top of the male connector, with the top of the spring abutting against the top wall of the male socket.

[0009] In some alternative implementations, a rubber component is also included, which is fitted onto the male socket, with the bottom surface of the male socket abutting against the upper surface of the rubber component, and the top surface of the locking component abutting against the lower surface of the rubber component.

[0010] In some alternative implementations, the outer wall of the male connector is provided with a limiting groove around the circumference of the male connector, and the rubber component is embedded in the limiting groove.

[0011] In some alternative implementations, the first assembly cavity is provided with a limiting thread, and the locking member is provided with an external thread that matches the limiting thread. The locking member is locked to the housing through the matching external thread and the limiting thread.

[0012] In some alternative implementations, the limiting thread is located at the bottom of the first assembly cavity, the inner wall of the locking member extends into a first annular boss in the axial direction of the first assembly cavity, and the bottom of the locking member abuts against the first annular boss.

[0013] In some alternative implementations, the top of the male connector abuts against the top wall of the first assembly cavity; the bottom of the male connector extends a second annular boss in a direction away from the axis of the first assembly cavity, and a flange is provided in the first assembly cavity, with the second annular boss abutting against the flange.

[0014] In some alternative implementations, the bottom of the locking member is provided with a clearance groove, and the female insert extends a limiting protrusion in an axial direction away from the first assembly cavity. When the female insert is inserted into the first assembly cavity from the bottom of the housing, the limiting protrusion is inserted into the clearance groove.

[0015] In some alternative implementations, the limiting thread is located at the top of the first assembly cavity, the inner wall of the locking member extends into a first annular boss in the axial direction of the first assembly cavity, and the top of the male connector abuts against the first annular boss. In some alternative implementations, the top of the female insert extends a locking portion in an axial direction away from the first assembly cavity. The locking member has a first through hole through which the female insert can pass. The inner wall of the locking member is provided with a locking portion and an access portion, which are staggered. The locking portion enters the first through hole of the locking member along the access portion. The female insert rotates relative to the locking member to move the locking portion to the locking portion, and the locking portion engages with the locking portion.

[0016] In summary, this utility model has at least the following advantages: This utility model provides a convenient connection joint structure for lamp installation. By sequentially placing the male connector and the locking component into the first assembly cavity of the housing, and locking them to the housing with a locking component, the male connector and the locking component are locked in the first assembly cavity, completing the fixed end assembly and preventing the internal components of the first assembly cavity from shifting. The female connector is inserted into the first assembly cavity from the bottom of the housing, simultaneously achieving electrical connection with the male connector and locking with the locking component. The entire assembly process requires no welding or screw tightening, only two steps of insertion and locking, which is convenient and stable, greatly improving production and maintenance efficiency. Even if the connection joint structure is subjected to long-term vibration, the female connector will not detach from the assembly cavity, completely solving the safety hazard of loose threads in traditional systems.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Example 1: This embodiment addresses the problem of the male-female plug structure in the prior art, where the limiting nut that mates with the female plug in the male plug structure is connected to the limiting thread of the hanging rod via an external thread. During the use of the chandelier, environmental vibrations may cause the threaded connection between the limiting nut and the hanging rod to gradually loosen, resulting in a decrease in the supporting force of the support part on the female plug. In severe cases, the limiting nut may fall off, causing the lamp to lose its mechanical fixation and posing a safety hazard. This embodiment provides a convenient connection joint structure for lamp installation.

[0031] Please see Figures 1-4 This embodiment provides a convenient connection connector structure for lamp installation, including: a housing 10, a male plug assembly 20, a female plug 30, a locking member 40, and a locking member 50. The housing 10 has a first assembly cavity. The male plug assembly 20 is disposed in the upper part of the first assembly cavity, and the locking member 40 is disposed in the lower part of the first assembly cavity. The locking member 50 is locked to the housing 10 to lock the male plug assembly 20 and the locking member 40 in the first assembly cavity. The female plug 30 is inserted into the first assembly cavity from the bottom of the housing 10 to engage with the locking member 50. The female plug 30 is inserted into the male plug assembly 20.

[0032] In this embodiment, the male connector 20 and the locking member 40 are assembled into the first assembly cavity, and then locked with the housing 10 by the locking member 50, thereby locking the male connector 20 and the locking member 40 into the first assembly cavity. Then, the female connector 30 is inserted from the bottom of the housing 10 into the first assembly cavity to engage with the locking member 50 and simultaneously engage with the male connector 20. The power cord of the assembled male connector 20 extends out of the top of the housing 10.

[0033] This embodiment provides a convenient connection joint structure for lamp installation. By sequentially placing the male connector 20 and the locking member 40 into the first assembly cavity of the housing 10, and locking them with the housing 10 by the locking member 50, the male connector 20 and the locking member 40 are locked in the first assembly cavity, completing the fixed end assembly and preventing the internal components of the first assembly cavity from shifting. The female connector 30 is inserted into the first assembly cavity from the bottom of the housing 10, simultaneously achieving electrical connection with the male connector 20 and locking with the locking member 40. The entire assembly process requires no welding or screw tightening, only two steps: insertion and locking, simplifying the assembly process, making it convenient and stable, and greatly improving production and maintenance efficiency. Even if the connection joint structure is subjected to long-term vibration, the female connector will not detach from the assembly cavity, completely solving the safety hazard of loose threads in traditional systems.

[0034] This embodiment is a preferred embodiment, and the structure of the locking member 40 has been optimized.

[0035] like Figure 5 As shown, the locking member 40 has a first through hole through which the female plug 30 can pass. The inner wall of the locking member 40 is provided with a locking part 41 and an access part 42, which are arranged alternately.

[0036] Specifically, a snap-fit ​​portion 31 extends from the top of the female plug 30 in an axial direction away from the first assembly cavity. The snap-fit ​​portions 31 are configured as a set, and the set of snap-fit ​​portions 31 is symmetrically arranged along the side wall of the female plug 30.

[0037] The inner wall of the locking member 40 is provided with an annular limiting platform 43. The access part 42 is set as a set. The set of access parts 42 is symmetrically arranged along the inner wall of the locking member 40, and the set of access parts 42 passes through the annular limiting platform 43 to divide the annular limiting platform 43 into two parts. The locking part 41 is located on the annular limiting platform 43, and its shape matches the locking part 31.

[0038] During assembly, the snap-fit ​​part 31 enters the first through hole of the locking member 40 along the access part 42, and the female plug 30 rotates relative to the locking member 40 to move the snap-fit ​​part 31 to the locking part 41, and the snap-fit ​​part 31 engages and locks with the locking part 41.

[0039] In this embodiment, the design of the insertion part 42 and the rotating locking part 41 allows the locking part 31 to be locked after it is inserted and rotated. The operation only requires two steps: insertion and rotation, which is quick and convenient. Moreover, the locking part 41 and the locking part 31 form opposite loads, and the greater the axial tensile force, the tighter the locking, which completely solves the problem of easy detachment of traditional locking.

[0040] The size of the access part 42 is slightly larger than that of the snap-fit ​​part 31, which can be compatible with the snap-fit ​​part 31 of the female plug 30 with a certain size deviation. It does not require strict size matching, reduces the requirements for component processing accuracy, and reduces production costs and rework rate.

[0041] When the female connector 30 is rotated to the locking part 41, a noticeable locking sensation will be produced. Workers can judge whether it is installed in place by touch, avoiding the problem of not locking due to the lack of feedback in traditional systems, and reducing the installation error rate.

[0042] This embodiment is a preferred embodiment, and the specific structure of the male connector 20 has been optimized.

[0043] In this embodiment, the male plug assembly 20 includes a male plug 21, a male socket 22, and a spring 23. The male socket 22 has a second assembly cavity, the male plug 21 is disposed in the second assembly cavity, the spring 23 is sleeved on the top of the male plug 21, and the top of the spring 23 abuts against the top wall of the male socket 22. The female plug 30 is inserted from the bottom of the housing 10 into the first assembly cavity to engage with the locking member 50, and at the same time engages with the male plug 21.

[0044] In addition, a third through hole 222 is provided at the top of the male socket 22 so that the power cord of the male plug 21 can pass through. After the power cord of the male plug 21 passes through the spring 23, it extends out through the third through hole 222. The top of the spring 23 abuts against the top wall of the male socket 22.

[0045] In this embodiment, a spring 23 is fitted on the top of the male plug 21. The top of the spring 23 abuts against the top wall of the male socket 22. The spring 23 can provide continuous elastic pressure, so that the male plug 21 is always in close contact with the female plug 30. Even if there are minor assembly errors or slight displacement caused by vibration, the deformation of the spring 23 can compensate for the current, ensuring stable current conduction and reducing faults such as lamp flickering and power failure.

[0046] In addition, the elastic buffer of spring 23 can reduce the impact force when the female plug 30 and male plug 21 are connected, avoid hard contact that could cause the male plug 21 pins to bend and the female plug 30 interface to be damaged, and extend the service life of the components; at the same time, it reduces the force required for plugging, so that workers can complete the connection without pressing hard, improving the ease of operation.

[0047] This embodiment, as a preferred embodiment, also includes a rubber component 60, which is sleeved on the male plug 21. The bottom surface of the male socket 22 abuts against the upper surface of the rubber component 60, and the top surface of the locking component 40 abuts against the lower surface of the rubber component 60.

[0048] In this embodiment, the rubber component 60 is fitted onto the male connector 21 and tightly abuts against the male socket 22 and the locking component 40, sealing the gap between the male connector assembly 20 and the locking component 40 to form an annular seal, preventing dust and moisture from entering the core area of ​​the electrical connection. The rubber component 60 is elastic, absorbing the impact of environmental vibrations on internal components and preventing wear caused by rigid collisions between the male connector assembly 20 and the locking component 40; it also reduces contact displacement between the male connector 21 and the female connector 30 caused by vibration, further ensuring the stability of the electrical connection. Furthermore, the elastic deformation of the rubber component 60 can compensate for assembly dimensional errors of the male connector assembly 20 and the locking component 40, ensuring a tight fit within the first assembly cavity, preventing loosening or displacement due to component processing errors, and improving the overall structural stability.

[0049] Preferably, the outer wall of the male plug 21 is provided with a limiting groove 211 around the male plug 21, and the rubber part 60 is embedded in the limiting groove 211.

[0050] In this embodiment, by providing a limiting groove 211 on the outer wall of the male plug 21 to lock the rubber part 60, the rubber part 60 is double-limited in both circumferential and axial directions, ensuring that the rubber part 60 is always fixed in the preset position of the male plug 21 and accurately abuts against the male socket 22 and the locking part 40, so that the sealing and buffering functions do not fail.

[0051] This embodiment is a preferred embodiment, and the connection structure between the housing 10 and the locking member 50 has been optimized.

[0052] In this embodiment, a limiting thread 11 is provided in the first assembly cavity of the housing 10, and the locking member 50 is provided with an external thread that matches the limiting thread 11. The locking member 50 is locked to the housing 10 through the matching external thread and the limiting thread 11.

[0053] In this embodiment, by using a threaded connection between the housing 10 and the locking member 50, the locking force between the housing 10 and the locking member 50 is more uniform and adjustable, which can firmly lock the male plug component 20 and the locking member 40 in the first assembly cavity, so that even if subjected to long-term impact and vibration, the internal components will not loosen.

[0054] The threaded connection between the housing 10 and the locking member 50 can be locked or disassembled by rotation without the need for special tools. During maintenance, only the locking member 50 needs to be rotated to remove the male connector 20 and the locking member 40 for inspection. The operation is convenient and reduces the difficulty and cost of maintenance.

[0055] Furthermore, by rotating the depth of the locking member 50, its clamping force on the internal components can be adjusted, adapting to male plug components 20 or locking members 40 of different thicknesses, without the need to reconstruct the structure of the housing 10, thus enhancing the versatility of the connector structure in this embodiment.

[0056] In this preferred embodiment, the limiting thread 11 is provided at the bottom of the first assembly cavity, and the inner wall of the locking member 50 extends into the first annular boss 51 in the axial direction of the first assembly cavity. The bottom of the locking member 40 abuts against the first annular boss 51.

[0057] In this embodiment, the first annular boss 51 provides a clear axial support reference for the locking member 40, ensuring that the locking member 40 is always at the preset height of the first assembly cavity and is precisely aligned with the locking part 31 of the female plug 30. This avoids the female plug 30 from failing to lock properly or becoming loose after locking due to displacement of the locking member 40, thus solving the locking deviation problem caused by traditional positioning without a reference.

[0058] Furthermore, the first annular boss 51 can evenly transfer the weight of the lamp borne by the locking member 40 to the locking member 50, and then to the housing 10 through the thread, avoiding local stress concentration on the locking member 40, which can lead to cracking and deformation, and extending the service life of the locking member 40; at the same time, it reduces the local bearing pressure of the housing 10 and improves the overall structural strength.

[0059] In this embodiment, since the limiting thread 11 is located at the bottom of the first assembly cavity, the male plug assembly 20 and the locking member 40 are sequentially inserted into the first assembly cavity of the housing 10 from the bottom of the housing 10, and then locked to the housing 10 by the locking member 50. At this time, the top of the male plug assembly 20 abuts against the top wall of the first assembly cavity; the bottom of the male plug assembly 20 extends a second annular boss 221 in a direction away from the axis of the first assembly cavity, and a flange 12 is provided in the first assembly cavity, and the second annular boss 221 abuts against the flange 12.

[0060] Specifically, the top of the male socket 22 of the male connector assembly 20 abuts against the top wall of the first assembly cavity. A second through hole 13 is provided on the top of the housing 10 to allow the power cord to pass through. A second annular boss 221 is provided at the bottom of the male socket 22.

[0061] In this embodiment, the top of the male socket 22 abuts against the top wall of the first assembly cavity, and the second annular boss 221 at the bottom of the male socket 22 abuts against the flange 12, forming a bidirectional limit in the upper and lower directions, with no axial movement space, ensuring that the male socket 21 and the female socket 30 are always precisely connected and the electrical connection is uninterrupted.

[0062] Furthermore, bidirectional positioning provides workers with a clear assembly endpoint, eliminating the need for repeated measurements and adjustments, and improving the precision of electrical connections and mechanical coordination.

[0063] Preferably, in order to ensure the accuracy of the insertion of the female plug 30, a relief groove 52 is provided at the bottom of the locking member 50, and a limiting protrusion 32 extends from the female plug 30 away from the axis of the first assembly cavity. When the female plug 30 is inserted into the first assembly cavity from the bottom of the housing 10, the limiting protrusion 32 is inserted into the relief groove 52.

[0064] In this embodiment, the limiting protrusion 32 is located on the side of the snap-fit ​​portion 31 away from the housing 10. When the female plug 30 is inserted into the snap-fit ​​member 40, the clearance groove 52 provides a circumferential mounting reference for the female plug 30. The worker only needs to align the limiting protrusion 21 with the clearance groove 52 to quickly insert it without repeatedly rotating and adjusting the angle of the female plug 30, and at the same time avoids component wear caused by angle deviation.

[0065] Example 2: This embodiment provides a convenient connection joint structure for lamp installation, which optimizes the assembly position of the locking member 50 and the housing 10 based on embodiment 1.

[0066] In this embodiment, as Figure 6-9 As shown, the limiting thread 11 is provided at the top of the first assembly cavity, and the inner wall of the locking member 50 extends into the first annular boss 51 in the axial direction of the first assembly cavity. The top of the male plug assembly 20 abuts against the first annular boss 51. Specifically, the top of the male socket 22 abuts against the first annular protrusion 51.

[0067] In this embodiment, since the limiting thread 11 is located at the top of the first assembly cavity, the locking member 40 and the male connector assembly 20 are sequentially inserted into the first assembly cavity of the housing 10 from the top of the housing 10, and then locked to the housing 10 by the locking member 50. At this time, the top of the male connector 22 abuts against the first annular boss 51, and the bottom of the locking member 40 abuts against the bottom wall of the first assembly cavity.

[0068] In this embodiment, by setting the limiting thread 11 at the top of the first assembly cavity, the locking member 50 is screwed in from the top of the housing 10, and the male connector 20 is pressed by the first annular boss 51, which is suitable for scenarios with limited top installation space and improves the applicability of the connection joint structure of this embodiment.

[0069] The top threaded connection facilitates the removal of the locking element 50 from above the luminaire and the maintenance of the male connector 20 without removing the entire housing 10. This is especially suitable for recessed luminaires, reducing maintenance difficulty and labor costs.

[0070] Furthermore, the first annular protrusion 51 is in full contact with the top of the male connector 20, and the clamping force is evenly distributed, preventing the male connector 20 from tilting due to localized force, ensuring that the male connector 21 and the female connector 30 are always vertically connected, the contact area of ​​the electrical connection point is stable, and the current conduction is uninterrupted.
