[0002] In the field of lighting fixtures, rotary connection structures are widely used to assemble fixture components. Common rotary connections rely primarily on rigid interlocking or threaded tightening between components to provide locking force. This rigid locking method lacks sustained elastic retention force. When the fixture is subjected to vibration or external impact, the locking structure is prone to gradually loosening due to stress relaxation or minor deformation, leading to mechanical connection failure. Therefore, how to provide a rotary connection structure that can resist vibration and maintain a stable locking state has become a pressing technical problem to be solved in this field.

[0005] In some embodiments, the female connector assembly includes a second base portion; the resilient latch is disposed on the second base portion.

[0006] In some embodiments, the male connector assembly includes a first base portion, on which a limiting portion is provided; when the male connector assembly is rotated to the predetermined position, the elastic latch engages with the limiting portion.

[0007] In some embodiments, the elastic latch is a cantilever beam structure with the second base portion protruding inward.

[0008] In some embodiments, the male connector assembly further includes a first conductive component disposed on the first base portion, and the female connector assembly further includes a second conductive component disposed on the second base portion; the mounting positions of the first conductive component and the second conductive component are configured such that when the male connector assembly is rotated to the predetermined position, the first conductive component and the second conductive component contact each other and form an electrical connection; before the predetermined position, the first conductive component and the second conductive component are spaced apart from each other.

[0009] In some embodiments, the second base portion is provided with an axially extending guide groove; the limiting portion can be aligned with and inserted into the guide groove during initial assembly to guide the rotation of the male connector assembly; and / or the second base portion is provided with a wire guide groove for the wire to pass through.

[0010] In some embodiments, the number of elastic latches is multiple and they are spaced apart along the circumferential direction of the female head assembly. The elastic latches can generate perceptible acoustic or tactile feedback when engaged.

[0011] In some embodiments, the first conductive component includes a male positive electrode spring and a male negative electrode spring, and the second conductive component includes a female positive electrode spring and a female negative electrode spring; the male positive electrode spring is correspondingly disposed with the female positive electrode spring, and the male negative electrode spring is correspondingly disposed with the female negative electrode spring.

[0013] According to another aspect of this application, an embodiment of the present invention provides a lamp that includes the above-described lamp rotation and fixing structure.

[0014] Compared with the prior art, the rotating and fixing structure of the lamp of this utility model has at least the following beneficial effects: The present invention provides a rotating and fixing structure for lamps, which includes a male connector assembly and a female connector assembly. The female connector assembly is provided with an elastic latch. The male connector assembly is rotatable relative to the female connector assembly and engages with the elastic latch when rotated to a predetermined position. The elastic latch locks the male connector assembly at the predetermined position when engaged.

[0015] This invention solves the problem of easy loosening of rigid locking in the prior art by using an elastic latch. The prior art points out that existing rotary connections rely on rigid engagement and lack elastic holding force, making them prone to loosening under vibration or impact. In this solution, the elastic latch engages with the male connector assembly when it rotates to a predetermined position, providing a continuous holding force to prevent the male connector assembly from rotating backward. Furthermore, this locking force originates from the elastic deformation and rebound of the elastic latch, effectively preventing the male connector assembly from rotating backward from the predetermined position, thus effectively resisting loosening.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] Example 1 This embodiment provides a rotating and fixing structure for a lamp, such as Figures 1-6 As shown, the rotating and fixing structure of the lamp includes a male connector assembly 1 and a female connector assembly 2; the female connector assembly 2 is provided with an elastic latch 21; the male connector assembly 1 can rotate relative to the female connector assembly 2, and when rotated to a predetermined position, it engages with the elastic latch 21, and the elastic latch 21 locks the male connector assembly 1 at the predetermined position when engaged.

[0024] The connection between male connector assembly 1 and female connector assembly 2 is a rotatable plug-in connection. Male connector assembly 1 can be inserted into female connector assembly 2 and rotate relative to it. More specifically, a resilient latch 21 is provided on female connector assembly 2. When male connector assembly 1 rotates to a predetermined position, resilient latch 21 engages with male connector assembly 1, and provides a continuous retaining force to prevent reverse rotation of male connector assembly 1 during engagement. Resilient latch 21 is typically located on the inner side or connecting surface of female connector assembly 2, interacting with the outer side or corresponding structure of male connector assembly 1 during rotation. The function of male connector assembly 1 is to serve as the movable part of the rotating connection of the lamp, realizing mechanical assembly and possible electrical transmission; the function of female connector assembly 2 is to serve as a fixed base, supporting and locking male connector assembly 1; the function of resilient latch 21 is that, after engagement, its continuous elastic deformation keeps the latch against the side wall of the limiting part, thereby preventing reverse rotation of male connector assembly 1 relative to female connector assembly 2, preventing loosening due to vibration or external force, and improving the stability of the overall structure.

[0025] The mating process between male connector assembly 1 and female connector assembly 2 begins with alignment and insertion. Male connector assembly 1 aligns with the openings of female connector assembly 2 and is inserted axially. More specifically, after insertion, male connector assembly 1 rotates relative to female connector assembly 2. During rotation, the elastic locking buckle 21 elastically deforms due to contact with male connector assembly 1. Furthermore, when rotated to a predetermined position, the elastic locking buckle 21 suddenly engages with the corresponding structure of male connector assembly 1, such as a groove or protrusion, producing a perceptible click sound and tactile feedback. At this point, the elastic locking buckle 21 rebounds and effectively prevents male connector assembly 1 from rotating back from the predetermined position, firmly locking male connector assembly 1 onto female connector assembly 2, completing the assembly. This mating method ensures a connection that is both quick and reliable.

[0026] The technical solution of this embodiment solves the problem of easy loosening of rigid locking in the prior art by using the elastic latch 21. The prior art points out that existing rotary connections rely on rigid fastening and lack elastic holding force, making them prone to loosening under vibration or impact. In this solution, the elastic latch 21 engages with the male connector assembly 1 when it rotates to a predetermined position and provides a continuous holding force to prevent the male connector assembly 1 from rotating in the opposite direction. Furthermore, this locking force originates from the elastic deformation and rebound of the elastic latch 21, which can adapt to external vibration and minor structural changes, always maintaining a tight connection, thereby effectively resisting loosening, improving the vibration resistance and long-term stability of the rotating fixing structure of the lamp, and overcoming the defect of weak locking in the prior art.

[0027] In a specific embodiment, the female head assembly 2 includes a second base portion 22; the elastic latch 21 is disposed on the second base portion 22.

[0028] The second base portion 22 serves as the core skeleton of the female connector assembly 2, providing structural support and a mounting base. The elastic latch 21 is directly attached to or formed on a specific part of the second base portion 22, such as its inner wall or end face, becoming an inseparable functional protrusion or spring arm on the base. This design makes the position and movement of the elastic latch 21 completely dependent on the geometry and spatial orientation of the second base portion 22, thereby ensuring that when the male connector assembly 1 is rotated into place, the elastic latch 21 can accurately extend from the second base portion 22 and participate in the interaction.

[0029] This embodiment achieves a compact integration and structural simplification of the mechanical locking function. More specifically, since the elastic latch 21 is directly disposed on the second base portion 22, the two form a unified whole. This avoids the use of additional independent elastic parts, reduces assembly steps and the number of parts, and lowers assembly complexity. Furthermore, this integrated arrangement allows the elastic deformation and restoring force generated by the elastic latch 21 when it is squeezed or engaged by the male connector 1 to be directly and efficiently transmitted to the entire connection interface through the second base portion 22, thereby enhancing transmission efficiency and reliability. At the same time, the integrated design also reduces fitting problems caused by the accumulation of tolerances of multiple parts, improving the stability and durability of the overall structure.

[0030] In a specific embodiment, the male connector assembly 1 includes a first base portion 11, on which a limiting portion 111 is provided; when the male connector assembly 1 is rotated to the predetermined position, the elastic latch 21 engages with the limiting portion 111.

[0031] This embodiment clarifies that the mechanical locking function of the male connector assembly 1 is jointly achieved by its core skeleton first base part 11 and the limiting part 111 disposed thereon. The first base part 11, as the main structural body of the entire male connector assembly 1, provides a stable bearing base for the limiting part 111. The limiting part 111 is a structure protruding from a specific position on the first base part 11 or a groove formed thereon. Its spatial position is precisely set. When the male connector assembly 1 rotates relative to the female connector assembly 2 and finally reaches the predetermined correct position, the elastic latch 21 from the female connector assembly 2 can just be inserted into or hooked into the limiting part 111, thereby completing the mechanical interlock. This design makes the locking action occur directly between the two structures, the first base part 11 and the elastic latch 21, ensuring that the transmission path of the locking force is the shortest and most direct.

[0032] This embodiment establishes a clear, reliable, and efficient mechanical locking point, thereby significantly improving the stability of the connection and its resistance to accidental loosening. More specifically, since the limiting part 111 is directly integrated into the first base part 11, its engagement with the elastic latch 21 constitutes a combination mechanism of rigid stop and elastic retention acting at the end of the rotation path. This mechanism not only prevents the male connector assembly 1 from continuing to rotate or reverse after locking through the physical structure of the limiting part 111, but more importantly, the elastic deformation generated when the elastic latch 21 engages with the limiting part 111 is converted into a continuous retaining force to prevent the male connector assembly 1 from reverse rotation. This force acts on the entire connection interface through the first base part 11, giving the connection an inherent toughness to resist vibration and impact. Furthermore, the presence of the limiting part 111 provides a clear and perceptible endpoint signal for the entire rotation assembly process. When the rotation is in place and engagement occurs, the user can clearly perceive that the operation is complete, which improves the accuracy of assembly and user experience. At the same time, this integrated design also simplifies the structure and enhances overall reliability.

[0033] In a specific embodiment, the elastic buckle 21 is a cantilever beam structure that protrudes inward from the second base portion 22.

[0034] The elastic latch 21 is not a separate component, but rather an integral part of the material of the second base portion 22. It extends from the base of the second base portion 22 through a beam-like design, with one end firmly connected to the base of the second base portion 22, while the other end remains free and points towards the internal space of the structure. More specifically, this cantilever beam shape endows it with inherent elasticity. When the male connector assembly 1 applies lateral pressure during rotation, the free end of the elastic latch 21 can flex like a spring. When the rotation is complete and the pressure is released, it rebounds due to the elasticity of the material itself, thus completing the locking action. The inwardly protruding design ensures that its movement trajectory precisely intersects with that of the limiting portion 111 on the male connector assembly 1, allowing the locking action to occur naturally at the predetermined end of the rotation path.

[0035] Because the cantilever beam itself is a one-piece structure extending from the base material, it eliminates the need to assemble individual springs or spring sheets, significantly simplifying the manufacturing and assembly process and improving the overall structural reliability. This one-piece molded cantilever beam provides a very direct and controllable elastic force. When it engages with the limiting part 111, its continuous attempt to return to its original shape is transformed into a holding force acting on the connection interface to prevent the male connector 1 from rotating in the opposite direction, effectively counteracting the tendency to loosen due to vibration. At the same time, the deformation and rebound process of the cantilever beam structure is clear and distinct, producing a "click" sound and tactile feedback that the user can perceive, thus naturally indicating that the installation is in place.

[0036] In a specific embodiment, the male connector assembly 1 further includes a first conductive component 12 disposed on the first base portion 11, and the female connector assembly 2 further includes a second conductive component 23 disposed on the second base portion 22; the mounting positions of the first conductive component 12 and the second conductive component 23 are configured such that when the male connector assembly 1 is rotated to the predetermined position, the first conductive component 12 and the second conductive component 23 contact each other and form an electrical connection; before the predetermined position, the first conductive component 12 and the second conductive component 23 are spaced apart from each other.

[0037] The first conductive component 12 is fixedly mounted on the first base portion 11 of the male connector assembly 1, typically connected by fasteners such as screws, and simultaneously connected to the power supply wires inside the lamp, thus serving as a bridge for current to flow from the male connector assembly 1 to the lamp load. Correspondingly, the second conductive component 23 is fixedly mounted on the second base portion 22 of the female connector assembly 2 in a similar manner and connected to an external power line, serving as a current input port. More specifically, the installation positions of these two conductive components are precisely configured so that when the male connector assembly 1 has not yet rotated to the predetermined position, the first conductive component 12 and the second conductive component 23 are spatially offset and maintain a physical distance from each other, at which point the circuit is in an open state. Only when the male connector assembly 1 rotates to the predetermined position and the elastic latch 21 and the limiting portion 111 complete the mechanical engagement, does the first conductive component 12 move to a position facing the second conductive component 23, achieving tight physical contact under structural pressure, thereby forming a stable electrical connection. The first conductive component 12 and the second conductive component 23 together constitute the core link of the electrical circuit. They are not only responsible for transmitting electrical energy to light up the lamps, but more importantly, their contact state is forced to be synchronized with the mechanical locking state, so that the on / off state of the circuit becomes a direct indication of whether the mechanical installation is in place, thereby playing the role of interlocking the electrical function with the mechanical structure.

[0038] During assembly, as the male connector assembly 1 rotates, the first conductive component 12 rotates along with the first base portion 11. Its trajectory is designed to avoid the second conductive component 23 until it reaches a predetermined position. As the rotation continues until the elastic latch 21 engages with the limiting portion 111, the angle of the male connector assembly 1 precisely aligns the first conductive component 12 with the second conductive component 23, forming reliable electrical contact under elastic or structural pressure. The beneficial effects of this approach are primarily the forced interlocking of electrical and mechanical safety, ensuring that the circuit can only be connected after the mechanical structure is securely locked. This completely avoids the risk of sparks, short circuits, or equipment damage that may occur if power is applied before proper installation, thus improving overall safety. Furthermore, this design uses electrical continuity as the final indicator of installation completion, providing users with another intuitive confirmation method besides auditory and tactile feedback—whether the light fixture illuminates normally. This multi-factor verification of installation correctness enhances operational reliability and user experience.

[0039] In a specific embodiment, such as Figure 2 As shown, the second base portion 22 has an axially extending guide groove 221; the limiting portion 111 can be aligned with the guide groove 221 and inserted during initial assembly to guide the rotation of the male connector assembly 1.

[0040] A groove structure extending axially, i.e., in the insertion direction, is specially provided on the second base portion 22 as a guide groove 221, and the limiting portion 111 provided on the first base portion 11 of the male connector assembly 1 corresponds to it in shape and position. During initial assembly, the user needs to manually align the limiting portion 111 of the male connector assembly 1 with the guide groove 221 of the female connector assembly 2 in a circumferential angle, and then insert the limiting portion 111 into the guide groove 221 axially. This insertion action causes the inner wall of the guide groove 221 to form a circumferential constraint on the limiting portion 111, ensuring that the male connector assembly 1 is in the only correct initial angular position with the female connector assembly 2 before subsequent rotation, and the axial insertion depth is also initially controlled, laying an accurate foundation for subsequent standard rotation operations.

[0041] Because the guide groove 221 provides a unique and clear path for the initial insertion of the limiting part 111, it eliminates the need for repeated attempts or precise angle judgments during installation. Users can simply align and push it in to complete the first step of positioning. This design effectively prevents the male connector assembly 1 from being forcibly rotated in an incorrect angular position, thus avoiding potential component jamming, scratches, or even structural damage, protecting the product and improving its durability. At the same time, the clear guidance makes the entire assembly process smoother and more intuitive, allowing even non-professional users to easily complete the process, improving the convenience and reliability of the product.

[0042] like Figure 4 As shown, the second base portion 22 is provided with a wire passage groove 222 for wires to pass through.

[0043] On the housing structure of the second base portion 22, grooves or recessed areas are designed and formed as wire passage channels 222. The size and path of this wire passage channel 222 are planned, and its opening usually faces the inside or side of the second base portion 22. Its main function is to provide a predetermined, shielded passage path for the power wires connected to the second conductive component 23. During assembly, the wires can be inserted from the inlet end of the wire passage channel 222, laid out along the direction of the channel, and finally led out from the outlet end and connected to the terminal block of the second conductive component 23, thereby completing the orderly arrangement of the internal wiring.

[0044] The cable tray 222 provides a dedicated and protected passage for the wires, enabling them to be neatly secured in their designated positions and preventing them from swinging or scattering freely within the second base 22. This avoids the wires potentially getting tangled or interfering with other moving parts such as the elastic latches 21, reducing the risk of short circuits or wear caused by messy wiring. This cable management method makes the internal space neater, facilitates heat dissipation, and makes the wiring readily visible during subsequent maintenance and inspection. Simultaneously, the wires being confined within the cable tray 222 also prevents them from being accidentally squeezed or hooked during the rotational assembly of the male connector assembly 1, thus protecting the integrity of the wire insulation and electrical connections.

[0045] In a specific embodiment, there are multiple elastic latches 21, which are distributed at intervals along the circumferential direction of the female head assembly 2.

[0046] On the second base portion 22 of the female connector assembly 2, there are not just one, but two or more such elastic structures. They are arranged on an annular path centered on the center of the second base portion 22 and are uniformly arranged at a specific angular distance from each other. These elastic latches 21 are all in the form of cantilever beams protruding inward from the second base portion 22. Their free ends all point towards the internal space and are distributed at equal intervals or according to a specific pattern along the circumference, thereby forming a ring of discontinuous but regular elastic contact points on the entire connection surface of the female connector assembly 2. These points together define multiple target positions for alignment and engagement required when the male connector assembly 1 is rotated to a predetermined position.

[0047] Because multiple elastic latches 21 are distributed circumferentially, when the male connector assembly 1 rotates into place, its limiting part 111 engages with these elastic latches 21 simultaneously or sequentially. This ensures that the force acting in the rotation direction is evenly distributed, avoiding local stress concentration or structural deformation that may be caused by single-point force application, thus ensuring a more stable connection that is less prone to loosening. This multi-point locking method can effectively resist vibrations or impacts from different directions because the external force is distributed to each elastic latch 21, with each latch contributing a portion of the holding force, greatly improving the overall stability of the structure in dynamic environments. Furthermore, the coordinated action of multiple elastic latches 21 can produce stronger and clearer acoustic and tactile feedback, such as a louder "click" sound and a more noticeable locking sensation, allowing the user to confirm that the installation is complete.

[0048] In a specific embodiment, such as Figure 3 As shown, the first conductive component 12 includes a male positive electrode spring 121 and a male negative electrode spring 122, as... Figure 4 As shown, the second conductive component 23 includes a female positive electrode spring 231 and a female negative electrode spring 232; the male positive electrode spring 121 is correspondingly arranged with the female positive electrode spring 231, and the male negative electrode spring 122 is correspondingly arranged with the female negative electrode spring 232.

[0049] The first conductive component 12 is not a single conductor, but consists of two independent spring components: a male positive spring 121 for connecting to the positive terminal of the power supply and a male negative spring 122 for connecting to the negative terminal of the power supply. They are separately installed and fixed on the first base portion 11. Similarly, the second conductive component 23 is also correspondingly decomposed into two independent spring components: a female positive spring 231 and a female negative spring 232 fixed on the second base portion 22. This corresponding arrangement means that in terms of spatial layout, when the male connector assembly 1 and the female connector assembly 2 are mated, the contact area of ​​the male positive spring 121 is designed to be exactly aligned with the contact area of ​​the female positive spring 231, and the contact area of ​​the male negative spring 122 is exactly aligned with the contact area of ​​the female negative spring 232, thereby forming a clear and one-to-one corresponding positive and negative electrode path preparation state.

[0050] This embodiment clearly distinguishes the conductive components into two independent pairs of contacts, positive and negative, and strictly defines their correspondence, ensuring that the current must flow along a predetermined positive and negative path. This fundamentally prevents potential dangers caused by incorrect wiring or accidental short circuits. This one-to-one correspondence is closely coordinated with the entire rotary interlocking mechanism. The male positive contact 121 only contacts the female positive contact 231 when rotated to a specific position, and the male negative contact 122 simultaneously contacts the female negative contact 232. This ensures that the complete electrical circuit is only connected at the moment the mechanical structure is fully locked in place, achieving forced synchronization of electrical conduction and mechanical locking, greatly improving safety in use.

[0051] In a specific embodiment, the elastic latch 21 can generate perceptible acoustic or tactile feedback when engaged.

[0052] When the elastic latch 21 engages with the limiting part 111 on the male connector assembly 1, this action is naturally accompanied by a clear audible sound or a noticeable tactile change felt by the user. This is because the elastic latch 21, as a flexible cantilever beam structure, bends and deforms under the rotational compression of the male connector assembly 1, accumulating energy. Once the rotation reaches the predetermined position, the elastic latch 21 quickly rebounds and impacts or engages with the corresponding structure of the limiting part 111. This rapid mechanical action causes a slight vibration in the structural components, producing an audible "click" sound. Simultaneously, when rotating the handle or component, a brief increase in resistance followed by a release of tactile feedback is felt. Both of these feedbacks are direct physical phenomena automatically generated when the connector is properly installed. This instantaneous feedback provides the user with a clear signal, allowing them to intuitively determine whether the male connector assembly 1 and the female connector assembly 2 have been rotated into place and are securely locked without relying on visual observation or other tools. This effectively prevents problems such as loose mechanical connections or poor electrical contact caused by incomplete installation. Furthermore, the clear feedback simplifies the installation process, allowing even non-professionals to easily complete the correct assembly, improving work efficiency and reducing the risk of installation errors, thus ensuring reliability and safety in use.

[0053] In a specific embodiment, such as Figure 3 As shown, the first base portion 11 is provided with a first positive electrode fixing hole 112 for mounting the male positive electrode spring 121 and a first negative electrode fixing hole 113 for mounting the male negative electrode spring 122; as Figure 4 As shown, the second base portion 22 is provided with a second positive electrode fixing hole 223 for installing the positive electrode spring 231 of the female connector and a second negative electrode fixing hole 224 for installing the negative electrode spring 232 of the female connector.

[0054] Specific mounting points for fixing each conductive spring are specially provided on the first base part 11 and the second base part 22. The first positive fixing hole 112 and the first negative fixing hole 113 are respectively machined at appropriate positions on the first base part 11. These two holes serve as precise positioning and fastening positions, so that the male positive spring 121 and the male negative spring 122 can be firmly locked onto them by screws or other fasteners. At the same time, the positive and negative wires of the power supply are also pressed and fixed together, thereby completing the reliable connection of the male side circuit. Correspondingly, the second positive fixing hole 223 and the second negative fixing hole 224 are provided on the second base part 22 in a similar manner. Their function is to provide the same stable mounting base for the female positive spring 231 and the female negative spring 232 and to reliably connect the external power line to it.

[0055] This embodiment ensures that each conductive component is precisely and securely positioned in space, enabling the male positive contact 121 and female positive contact 231, and the male negative contact 122 and female negative contact 232, to accurately align and contact when rotated into place. This is the foundation for achieving reliable electrical connection and forced interlocking function. More specifically, dedicated fixing holes simplify the assembly process, allowing operators to clearly and accurately install each contact into the designated hole and complete contact fixing and wire crimping in one go using screws, improving production efficiency and reducing the risk of wiring errors. Furthermore, this robust mechanical fixing method effectively prevents the contacts from shifting or loosening due to vibration or insertion / removal forces during use, ensuring the long-term stability and safety of the electrical connection. At the same time, this structure also facilitates the neat routing of wires to the wire channel 222, helping to maintain clean and orderly internal wiring of the component, reducing line interference, and thus improving the overall reliability and service life of the product.

[0056] The working process of the lamp rotation fixing structure provided in this embodiment begins with the initial docking of the male connector assembly 1 and the female connector assembly 2. At this time, the user needs to align the limiting part 111 on the male connector assembly 1 with the axially extending guide groove 221 opened on the second base part 22 of the female connector assembly 2 and insert it. This action ensures that the two components start to assemble in the correct angular position and limits the axial insertion depth. Then, the user rotates the male connector assembly 1 clockwise, so that its first base part 11 rotates relative to the second base part 22. During this rotation, the limiting part 111 on the male connector assembly 1 moves along a preset path and begins to contact the multiple elastic latches 21 protruding inward on the second base part 22. These elastic latches 21 are distributed at intervals along the circumference of the female connector assembly 2. As a cantilever beam structure, it undergoes elastic bending deformation and accumulates energy when squeezed by the limiting part 111. When the male connector assembly 1 rotates to the predetermined position, the elastic latch 21 suddenly rebounds and engages with the corresponding structure of the limiting part 111, producing a clear clicking sound and tactile feedback, indicating that the mechanical locking is complete. At the same time, the elastic latch 21 provides a continuous holding force to prevent the male connector assembly 1 from rotating in the opposite direction due to the rebound. At the instant that this mechanical locking action occurs simultaneously, the male positive electrode spring 121 and male negative electrode spring 122 installed on the male connector assembly 1 through the first positive electrode fixing hole 112 and the first negative electrode fixing hole 113, also rotate with the first base part 11 to a position where they are completely aligned with the female positive electrode spring 231 and female negative electrode spring 232 installed on the female connector assembly 2 through the second positive electrode fixing hole 223 and the second negative electrode fixing hole 224, forming a tight physical contact, thereby establishing a complete electrical circuit and realizing power supply; at any position before rotating to the final position, these springs are spaced apart to ensure that the circuit is disconnected. Throughout the assembly process, the wires connected to the conductive spring are neatly arranged through the wire groove 222 on the second base part 22 to avoid interference. At this point, the elastic latch 21 is engaged with the limiting part 111 by mechanical rotation, and the electrical connection between the first conductive part 12 and the second conductive part 23 is forcibly and synchronously realized. The entire rotating and fixing structure of the lamp completes the continuous working process from alignment, insertion, rotation locking to circuit conduction.

[0057] Example 2 This embodiment provides a lamp, characterized in that the lamp includes the lamp rotation and fixing structure described in Embodiment 1.

[0058] Applying the rotating and fixing structure of the lamp in Embodiment 1 to the lamp provides a continuous locking force that resists vibration and impact for the connection between lamp components through the engagement mechanism of its elastic latch 21 and the limiting part 111. This fundamentally solves the problem of easy loosening of traditional rigid connections and ensures the structural stability of the lamp during long-term use. At the same time, its unique interlocking design requires that the circuit can only be connected after the mechanical rotation is in place, which completely eliminates the risk of live operation due to incomplete installation and greatly enhances electrical safety. In addition, the guidance of the guide groove 221 and the clear auditory and tactile feedback generated when the elastic latch 21 engages make the lamp installation process simple, intuitive and the result clear and accurate.

[0059] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
