[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0019] See Figures 1 to 11 The present invention provides a hook connector, including a mounting chamber 11. A conductive hook assembly 18 is fixedly installed inside the mounting chamber 11. A contact inner ring 14 and a contact outer ring 13 are provided at the bottom of the mounting chamber 11. The other end of the conductive hook assembly 18 passes through the bottom of the mounting chamber 11 and abuts against the contact inner ring 14 and the contact outer ring 13. The contact inner ring 14 and the contact outer ring 13 are respectively connected to a power cord 20. The other end of the power cord 20 is connected to the power board of the lamp.
[0020] The conductive hook assembly 18 is an integrated component with conductive and mechanical hanging functions. Its overall structure must meet the requirements of conductive continuity, mechanical strength and elastic contact. The conductive hook assembly 18 is fixed inside the mounting chamber 11 by fasteners. Its upper end forms a hook part for hanging lamps, and its lower end extends downward and penetrates the bottom of the mounting chamber 11 to achieve physical contact and electrical connection with the contact ring below. The conductive path of the conductive hook assembly 18 covers the entire length from the hook part to the contact end. The preferred material is copper, and the specific material can be selected according to the requirements of current carrying capacity and corrosion resistance.
[0021] The inner contact ring 14 and the outer contact ring 13 are concentrically arranged annular conductive elements, and are electrically isolated from each other. The outer contact ring 13 is located on the outside and the inner contact ring 14 is located on the inside, together forming a bipolar conductive interface. The axial height, radial spacing and flatness of the two can be adapted and set according to the bottom structure of the mounting compartment 11. The bottom end of the outer contact ring 13 is provided with crimp terminals, solder pins or plug terminals for reliable connection with the power line 20.
[0022] The other end of the conductive hook assembly 18 passes through the bottom of the mounting chamber 11 and abuts against the inner contact ring 14 and the outer contact ring 13. The abutment method is elastic pressing or rigid pressing. The surface of the abutment part can be plated with nickel, silver or tin to enhance conductivity and oxidation resistance. The abutment pressure can be provided by the structural elasticity of the conductive hook assembly 18 itself, additional springs or pre-compression springs to ensure that stable contact resistance is maintained under conditions such as vibration and thermal expansion and contraction. The inner contact ring 14 and the outer contact ring 13 are respectively connected to wires of different polarities in the power line 20. For example, the outer contact ring 13 is connected to the neutral wire and the inner contact ring 14 is connected to the live wire, so that a complete circuit is constructed at the same time as the hook is attached.
[0023] The other end of the power cord 20 is used to connect to the power board of the lamp. The connection method includes solder connection, IDC solderless crimping, screw terminal connection or quick connector connection, preferably quick connector connection. The power board can be an LED driver power board, a constant current source module or an intelligent dimming control board, and its input interface is matched one by one with the output end of the power cord 20. After the power cord 20 is led out of the mounting compartment 11, it can be laid along the inner wall of the lamp housing and fixed by wire slots, cable tie holes or wire passage holes to avoid loosening of the contact due to pulling.
[0024] Through the above technical solution, the lower end of the conductive hook assembly 18 automatically forms a stable contact with the inner contact ring 14 and the outer contact ring 13 at the same time as the lamp hanging action is completed, so that the current forms a complete path through the conductive hook assembly 18 → inner contact ring 14 / outer contact ring 13 → power line 20 → lamp power board; no additional wiring or connection operation is required, which significantly improves installation efficiency; the separate layout of inner and outer rings and physical isolation structure effectively prevent short circuits between poles; and the through conductive path and elastic contact design ensure contact reliability and electrical stability under long-term use.
[0025] The mounting chamber 11 is integrally injection molded, with a rectangular chamber wall 110 as its main body. The chamber wall 110 has staggered ribs 111 inside, each with a mounting groove 112 for fixing the conductive hook assembly 18. The bottom of the mounting chamber 11 extends downwards to form an outer convex ring 116, an inner convex ring 117, and a central post 118 located at the center of the inner convex ring 117. A first annular mounting area is formed between the outer convex ring 116 and the inner convex ring 117 for mounting the outer contact ring 13; a second annular mounting area is formed between the inner convex ring 117 and the central post 118 for mounting the inner contact ring 14. A notch 113 is provided on the side wall of the mounting chamber 11 to allow for and install the release button 12. Fixing lugs 114 are provided at both ends of the mounting chamber 11, and screws are used to fix the mounting chamber 11 to the lamp housing. The outer convex ring 116 has cover grooves 115 on both sides. The cover grooves 115 have nut positioning holes and bayonets for installing the nylon top cover 15, providing insulation protection and improving the appearance. The inner side of the nylon top cover 15 has a hook. The hook and bayonets are engaged to achieve the connection between the nylon top cover 15 and the installation chamber 11.
[0026] Ribs 111 are arranged in a crisscross pattern along the inner side of the bin wall 110 to form a grid-like support frame. The cross-sectional shape of the ribs 111 can be rectangular, trapezoidal, or arc-shaped, and the height can be 0.8 to 1.5 times the thickness of the bin wall 110. The crisscross arrangement can evenly distribute the stress from the hook part and the stress generated during assembly and fastening, thereby improving the bending stiffness and torsional stability of the installation bin 11 under long-term suspended load. The number, spacing, and intersection angle of the ribs 111 can be adjusted according to the mold process and structural strength requirements.
[0027] The outer convex ring 116, the inner convex ring 117, and the central column 118 are all integrally formed from the bottom of the mounting chamber 11 and extend downwards. The three are arranged coaxially with their axis perpendicular to the bottom surface of the mounting chamber 11. The outer convex ring 116 is an annular protrusion with an outer diameter slightly smaller than the outer contour of the bottom surface of the mounting chamber 11. The inner convex ring 117 is an annular protrusion concentrically set inside the outer convex ring 116 with an inner diameter larger than the outer diameter of the central column 118. The central column 118 is a solid cylinder with a height that is basically the same as or slightly higher than that of the inner convex ring 117. It is used to provide bottom structural support and limit the axial displacement of the inner contact ring 14. The radial dimension relationship between the outer convex ring 116, the inner convex ring 117, and the central column 118 can be set according to the matching dimensions of the outer contact ring 13 and the inner contact ring 14.
[0028] This technical solution utilizes the bin wall 110 and internal interlaced ribs 111 to form a high-strength support frame, improving the overall rigidity and deformation resistance of the installation bin 11 without significantly increasing its volume. The mounting grooves 112 on the ribs 111 ensure precise axial and circumferential positioning of the conductive hook assembly 18, preventing poor contact due to assembly deviations. The double-ring mounting area formed by the outer convex ring 116, inner convex ring 117, and central column 118 provides independent and stable mounting and positioning for the outer contact ring 13 and inner contact ring 14, effectively suppressing their displacement and loosening under vibration or thermal expansion and contraction conditions. The central column 118 further strengthens the support stability of the bottom structure, preventing the bottom of the installation bin 11 from collapsing, thus ensuring long-term reliable electrical conduction between the conductive hook assembly 18 and the two contact rings.
[0029] See Figure 7 and Figure 8 The conductive hook assembly 18 is formed by fixing copper hooks 181 and contact springs 182 together with screws. The two copper hooks 181 are diagonally distributed. The copper hooks 181 are made of brass material and are stamped and formed. They include a vertical hanging arm 1813. The top of the hanging arm 1813 is bent at 90 degrees to form a hook 1814, which is used to cooperate with the hanging groove of the mounting base to achieve quick hanging. The bottom of the hanging arm 1813 is bent at 90 degrees to form a fixing plate 1811. The fixing plate 1811 has a first through hole 1812.
[0030] The contact spring 182 is made of stamped copper. Its top has a fixing piece 1821 that abuts against the fixing plate 1811. The fixing piece 1821 has a second through hole 1822 at its center, corresponding to the first through hole 1812. Multiple protrusions surround the second through hole 1822 to increase contact strength with the screw and prevent loosening. The fixing piece 1821 extends diagonally downwards to form a first elastic arm 1823 and a second elastic arm 1824. The width of the first elastic arm 1823 is greater than the width of the second elastic arm 1824 to optimize the elastic force transmission path. Reinforcing ribs 1825 are provided on the outer surfaces of the first elastic arm 1823 and the second elastic arm 1824 to improve structural strength. The bottom end of the second elastic arm 1824 is bent to form a pressure plate 1826. The center of the pressure plate 1826 is recessed downwards to form a pressing part 1827, which is used to form surface contact with the inner contact ring 14 or the outer contact ring 13. Two sets of conductive hook assemblies 18 are fixed in the mounting groove 112 by screws. The hooks 1814 extend upwards from the top of the mounting chamber 11, and the pressing part 1827 penetrates downwards through the bottom of the mounting chamber 11, respectively abutting against the inner contact ring 14 and the outer contact ring 13 to form an electrical path.
[0031] The width of the first elastic arm 1823 is greater than that of the second elastic arm 1824. This means that at the same cross-sectional position along the extension direction of the elastic arm on the contact spring 182, the dimension of the first elastic arm 1823 in the direction perpendicular to its length is greater than the dimension of the second elastic arm 1824 in the corresponding direction. The difference in width constitutes an asymmetric stiffness distribution structure, so that the first elastic arm 1823, as the main load-bearing section, undertakes the main bending deformation and torque transmission, while the second elastic arm 1824, as the transition section, guides the deformation path and releases local stress. The width ratio of the first elastic arm 1823 to the second elastic arm 1824 can be set according to the actual contact pressure, rebound stroke, and fatigue life requirements.
[0032] The reinforcing ribs 1825 are disposed on the outer surfaces of the first elastic arm 1823 and the second elastic arm 1824, extending along the length of the elastic arm. Their cross-sectional shape is a rectangular, trapezoidal, or arc-shaped protrusion, and their height is set according to the bending stiffness requirements. The number of reinforcing ribs 1825 can be one or more. For example, two parallel reinforcing ribs 1825 are disposed on the outer surface of the first elastic arm 1823, and one centrally located reinforcing rib 1825 is disposed on the outer surface of the second elastic arm 1824. The reinforcing ribs 1825 are integrally formed into the contact spring 182 body by stamping, etching, or injection molding insert processes, and their material is the same as the substrate of the contact spring 182. The placement, number, height, and cross-sectional shape of the reinforcing ribs 1825 can be adjusted adaptively according to actual needs.
[0033] The outer surfaces of the first elastic arm 1823 and the second elastic arm 1824 refer to the surfaces facing the outside of the mounting chamber 11 and away from the fixing plate 1821; the reinforcing ribs 1825 are provided on the surface, without changing the assembly gap between the inner side of the elastic arm and the adjacent structure, and without affecting the degree of freedom of movement and contact posture of the pressing plate 1826 and the pressing part 1827.
[0034] This technical solution achieves higher bending stiffness in the first elastic arm 1823 due to its larger width, which bears the main elastic deformation during the downward movement of the conductive hook 1814 assembly 18 under pressure, thus suppressing plastic yielding caused by overload. The second elastic arm 1824 has better flexibility due to its smaller width, and can bend under a smaller driving force, so that the pressing part 1827 can smoothly fit against the inner ring 14 or the outer ring 13 surface. The reinforcing rib 1825 further increases the overall moment of inertia of the elastic arm section, enhancing its resistance to torsion and lateral buckling.
[0035] The copper hook 181 is a one-piece metal part formed by integral stamping. Its material is brass, copper, or copper alloy. It is used to carry the main circuit current and realize the external suspension function. The vertical hanging arm 1813 extends longitudinally along the interior of the mounting chamber 11. Its cross-sectional shape is rectangular, circular, or elliptical, and its size is set according to the actual current carrying requirements. The hook 1814 is formed by the horizontal or inclined bending of the top of the hanging arm 1813, and its opening direction is upward. The fixing plate 1811 is formed by the horizontal or inclined bending of the bottom end of the hanging arm 1813. It is located on the inner side of the bottom of the mounting chamber 11 and is used to provide an assembly reference surface with the contact spring 182. The first through hole 1812 is a circular through hole located in the central area of the fixing plate 1811. Its diameter is set according to the screw specifications used.
[0036] The contact spring 182 is an elastic metal structure used to provide continuous and stable contact pressure after assembly; the fixing plate is the top bearing area of the contact spring 182, and its shape is adapted to the contour of the fixing plate 1811, so that it can be flat and fit against the surface of the fixing plate 1811; the second through hole is a circular through hole arranged coaxially with the first through hole 1812, and its diameter is slightly larger than that of the first through hole 1812, so as to accommodate the screw and achieve a pressing fit between the two through fastening; the first elastic arm and the second elastic arm form a continuously curved elastic cantilever structure, and its width, thickness and bending angle are adjusted according to the required elastic force and compression stroke; the pressure plate is formed by bending the bottom end of the second elastic arm, and its plane is perpendicular to the extension direction of the second elastic arm, so as to concentrate the elastic deformation force to the contact area; the pressing part is an arc-shaped or spherical crown-shaped pit formed by the downward concavity of the center of the pressure plate, and its radius of curvature is set according to the surface morphology of the contact ring. The concave structure makes the pressing part form a conductive contact with the inner contact ring 14 or the outer contact ring 13.
[0037] The copper hook 181 and the contact spring 182 are mechanically fastened and electrically connected by screws passing through the first through hole 1812 and the second through hole; the screw length ensures that the fixing piece is pressed against the surface of the fixing plate 1811 when tightened, and the pressing part applies a preset contact pressure to the contact ring; the connection method avoids hot working or non-removable connection processes such as welding and riveting, which facilitates separate manufacturing, independent inspection and subsequent replacement and maintenance.
[0038] The pressing part forms a conductive contact with the inner contact ring 14 or the outer contact ring 13. After the hook connector 10 is assembled, the lower end of the conductive hook assembly 18 passes through the bottom of the mounting chamber 11, and the pressing part abuts against the upper surface of the inner contact ring 14 or the upper surface of the outer contact ring 13 respectively. The normal pressure is generated by the elastic deformation of the contact spring 182, so that the pressing part and the corresponding contact ring remain in continuous contact.
[0039] Through this technical solution, the lead-hook connector 10 achieves modular design and reliable conductive connection of the conductive hook assembly 18: the copper hook 181 serves as the main load-bearing component, providing high conductivity and structural rigidity; the contact spring 182 serves as an elastic contact component, providing stable, adjustable, and durable contact pressure within a limited space through a multi-stage elastic arm structure and a recessed design of the pressing part; the two are fastened together by coaxial through holes and screws, ensuring low-resistance continuity of the electrical path while also taking into account assembly tolerance adaptability and maintainability; thus, without changing the overall structure of the lead-hook connector 10, the conductive reliability, assembly convenience, and long-term contact stability are significantly improved.
[0040] See Figure 2 , Figure 4 and Figure 12 The release button 12 and the latch 19 are installed at the notch 113, and the two are engaged by a wedge-shaped inclined surface. A compression spring is provided below the latch 19 to provide the reset force. When the release button 12 is pressed, the wedge-shaped inclined surface converts the vertical pressing force into a horizontal thrust, pushing the latch 19 to move laterally.
[0041] The hook connector 10 is used to connect to a female end seat located on the ceiling. A copper hook 181 is used to attach to the female end seat. The female end seat has a pair of centrally symmetrical arc-shaped openings, each including a long, narrow arc segment and a short, wide arc segment. During connection, the copper hook 181 is first inserted into the short arc segment, then rotated into the long arc segment, and finally locked in place by the locking buckle 19 located in the short arc segment. Pressing the release button 12 releases the lock. Reverse rotation allows the copper hook 181 to gently disengage from the female end seat. Without pressing the release button 12, the copper hook 181 is securely connected to the female end seat.
[0042] The notch 113 is a rectangular or trapezoidal through slot opened on the side wall of the installation chamber 11. Its size and position are set according to the assembly space requirements of the release button 12 and the latch 19. It can accommodate the pressing stroke of the release button 12 in the vertical direction and the sliding stroke of the latch 19 in the horizontal direction. The edge structure of the notch 113 can be set according to the actual situation. For example, a guide chamfer or a limiting step can be set to guide the release button 12 into place and limit its excessive displacement.
[0043] The release button 12 is a block or columnar structure with a wedge-shaped working surface. Its wedge-shaped surface and the mating surface of the latch 19 are arranged in a complementary inclined plane. The wedge angle can be set according to the required mechanical gain ratio. The exposed end of the release button 12 is provided with anti-slip texture or raised structure to facilitate the user to apply force.
[0044] The latch 19 is a strip-shaped or L-shaped component that can slide horizontally within the notch 113. The side of the latch that engages with the release button 12 has an inclined surface that matches the wedge-shaped surface. The sliding path of the latch 19 is constrained by the guide rail groove or limiting rib provided inside the installation chamber 11.
[0045] The return spring is a compression coil spring, with one end abutting against the end of the latch 19 and the other end abutting against a spring seat or baffle pre-set on the inner wall of the mounting chamber 11; the elastic force of the return spring is set according to the locking and retaining force required by the latch 19.
[0046] This technical solution enables the efficient conversion of vertical pressing force into horizontal unlocking driving force using a wedge-shaped surface, reducing the user's operating force; the return spring provides a stable and reliable self-resetting capability, ensuring that the latch 19 is always in a pre-loaded locked state, preventing accidental disengagement; the notch 113, release button 12, latch 19 and return spring constitute a compact and integrated linear unlocking mechanism.
[0047] See Figure 9 and Figure 10 The annular shell 16 is integrally injection molded and includes a circular base 160. The edge of the base 160 extends upward to form an outer annular wall 161, and the center of the base 160 extends upward to form a middle ring 162, whose height is less than that of the outer annular wall 161. The central area of the base 160 extends upward to form an inner ring 163. An annular groove is provided on the inner side of the middle ring 162, and a retaining hole 166 is provided in the groove for positioning the pins that contact the outer ring 13. The bottom of the base 160 extends downward to form an outer arc wall 164 and an inner arc wall 165. A first wiring area is formed between the outer arc wall 164 and the inner arc wall 165, and a second wiring area is formed inside the inner arc wall 165. The pins that contact the outer ring 13 pass through the retaining hole 166 and extend to the first wiring area, while the pins that contact the inner ring 14 pass through the inner ring 163 and extend to the second wiring area. The inner arc wall 165 is connected to guide walls 167 at both ends to guide the direction of the wire; the outer arc wall 164 is provided with hollow columns 168 for positioning and fixing the bottom cover 17.
[0048] The annular shell 16 is an independently molded insulating structural component, and its material can be set according to actual conditions, such as flame-retardant polycarbonate, modified polypropylene, or engineering plastic ABS. The circular base 160 is arranged horizontally, and its outer diameter is adapted to the bottom contour of the mounting chamber 11, which can cover the entire exposed area of the bottom of the mounting chamber 11. The outer ring wall 161, the middle ring 162, and the inner ring 163 all extend vertically upward along the axial direction of the base 160. The three are arranged concentrically, and their heights decrease sequentially. The outer ring wall 161 is the highest and is used to form a limiting fit with the lamp housing or mounting bracket. The middle ring 162 is used to support and position the installation position of the contact outer ring 13. The inner ring 163 is used to enclose and support the installation area of the contact inner ring 14.
[0049] Both the outer arc wall 164 and the inner arc wall 165 are formed by extending downward from the bottom surface of the chassis 160. Both are arc-shaped sidewalls, coaxially arranged, and the radius of the outer arc wall 164 is larger than that of the inner arc wall 165. The annular gap between the outer arc wall 164 and the inner arc wall 165 constitutes the first wiring area, which is used to accommodate the pins that contact the outer ring 13 and the power line branches connected thereto. The central area enclosed by the inner arc wall 165 constitutes the second wiring area, which is used to accommodate the pins that contact the inner ring 14 and the corresponding power line branches. The first wiring area and the second wiring area are spatially isolated from each other to avoid interference or creepage risks between lines with different potentials.
[0050] The pins of the outer ring 13 extend vertically downward from the bottom of its body and enter the first wiring area after passing through the card hole 166 provided on the inner side of the middle ring 162; the pins of the inner ring 14 extend vertically downward from the bottom of its body and enter the second wiring area through the central opening of the inner ring 163; each pin maintains a natural hanging state in the corresponding wiring area or is constrained by the guide wall to reduce bending stress; the guide wall is connected to both ends of the inner arc wall 165 and has an arc-shaped sheet structure that slopes inward, used to guide the power line so that it smoothly transitions to the connection end of the lamp power board along a predetermined path.
[0051] This technical solution enables the annular shell 16 to serve as an independent protective structure covering the underside of the installation chamber 11. The chassis 160 and the upper and lower extending annular walls together form a closed wiring cavity with physical isolation function. The partition structure formed by the outer arc wall 164 and the inner arc wall 165 allows the pins of the contact outer ring 13 and the contact inner ring 14 to be respectively arranged in the first wiring area and the second wiring area that are not connected to each other, thereby achieving effective isolation of high and low voltage lines in space. The guide wall, together with the arc wall structure, guides and constrains the power line routing, reducing the probability of cable bending damage.
[0052] The inner arc wall 165 is connected to guide walls 167 at both ends to guide the direction of the power line.
[0053] The inner arc wall 165 is an arc-shaped sidewall extending downward from the center area of the chassis 160 of the annular shell 16. Its axial height, radial thickness, and radius of curvature are set according to the actual assembly space and the matching requirements of the power line outer diameter. The guide wall 167 is a strip-shaped or arc-shaped extension structure connected to both ends of the inner arc wall 165 along the circumference, forming a limit and guide for the path of the power line entering the second wiring area. The extension direction of the guide wall 167 is consistent with the natural routing trend of the power line after it is led out from the contact inner ring 14 pin, so that the power line bends gently along the surface of the guide wall when entering the second wiring area, avoiding sharp bends smaller than the minimum allowable bending radius of the power line. The width, thickness, and cross-sectional shape of the guide wall are not specially limited. The guide wall can be integrally injection molded with the annular shell 16, or it can be fixed by inserts, clips, or ultrasonic welding.
[0054] The power cord assembly 20 includes two parallel insulated power cords. One power cord is soldered to the pin of the outer contact ring 13 and extends to the first wiring area. The other power cord is soldered to the pin of the inner contact ring 14 and extends to the second wiring area. The other ends of the two power cords are respectively connected to the power board of the lamp, realizing the two poles separate wiring.
[0055] This technical solution achieves the following: by setting guide walls 167 at both ends of the inner arc wall 165, the power line is actively constrained when it is led out from the contact inner ring 14 pin, avoiding disorderly bending and mutual interference. Since the guide walls provide a continuous and smooth guiding path, the bending radius of the power line in the second wiring area is kept above the safety threshold, reducing the risk of insulation layer cracking and conductor breakage. The neat arrangement of the power line can be achieved without additional positioning, improving the overall installation efficiency of the hanger connector 10.
[0056] The bottom cover 17 is circular and can be injection molded from ABS material. It has hooks on its edge that can be snapped into the slots in the cover groove 115 to achieve tool-free installation. The bottom cover 17 has fixing holes corresponding to the hollow column 168 and is fixedly connected to the annular shell 16 by screws to form a complete bottom sealing structure.
[0057] The working process of this invention is as follows: During installation, the lamp's hanging connector 10 is pushed upwards into the hanging groove of the ceiling mounting base. The hook 1814 of the conductive hook assembly 18 engages with the hanging groove to achieve initial positioning. The latch 19 automatically engages with the locking hole of the base under the action of the spring, completing the mechanical locking. At the same time, the pressing part 1827 tightly abuts against the inner contact ring 14 and the outer contact ring 13, forming a stable electrical path. During disassembly, pressing the release button 12 causes the wedge-shaped surface to push the latch 19 to move laterally and disengage from the locking hole, allowing the lamp to be removed.
[0058] The hook connector provided by this invention has the following advantages: This invention provides a hook-and-mount connector. This design achieves electrical connection between the luminaire and the mounting base by fixing a conductive hook assembly inside the mounting chamber, with the other end of the conductive hook assembly penetrating the bottom of the mounting chamber and abutting against the inner and outer contact rings. By using the bottom ends of the inner and outer contact rings to connect the power cord, and the other end of the power cord connecting to the luminaire's power board, a complete electrical path is formed. This design simplifies the installation process of luminaires using the hook-and-mount connector, avoids the complex electrical connection structure of traditional connectors, and improves production efficiency. The structural design of the mounting chamber allows for stable fixation of the conductive hook assembly, ensuring the reliability of the electrical connection. The arrangement of the inner and outer contact rings enables separate wiring between the two poles, effectively preventing short-circuit risks. The structure of the conductive hook assembly penetrating the bottom of the mounting chamber and abutting against the contact rings eliminates the need for additional connectors, reduces assembly steps, and improves assembly efficiency. This integrated electrical connection design not only simplifies the manufacturing process but also improves product reliability, enabling the hook-and-mount connector to quickly and stably achieve luminaire installation and electrical connection in practical applications, effectively solving the problem of low assembly efficiency in existing technologies.
