A lamp splicing and fixing connector Technical Field
[0001] This utility model belongs to the field of linear light technology, and specifically relates to a lamp splicing and fixing connector. Background Technology
[0002] In modern architectural decoration and lighting engineering, modular lighting fixtures such as linear lights are widely used due to their aesthetic appeal, flexibility, and ease of installation. To achieve seamless splicing and electrical connection between lighting fixtures, fixed connectors are typically used to mechanically fix adjacent light bodies and ensure electrical continuity. However, existing lighting fixture splicing structures mostly employ single spring clips or snap-fit connections, which have several shortcomings in practical applications.
[0003] First, traditional connection methods often rely on simple spring clips or clips to fix the lamps together, resulting in poor connection stability. Especially during installation or use, external forces such as pulling or vibration can easily cause the lamps to loosen or even detach, affecting the overall structural safety and lifespan. Second, existing connection structures also have significant defects in electrical connections. The terminals between the two lamp bodies are not tightly connected, easily leading to poor contact due to improper installation or long-term use. This can cause the circuit to overheat, spark, or even the lamp to go out, seriously affecting the stable operation of the lamp and even creating safety hazards. Particularly during installation and assembly, improper operation or forceful pulling of the lamp wires can easily cause the terminals to detach or not fully engage, resulting in the lamp failing to light up or suddenly losing power during operation. This not only affects construction efficiency but also increases later maintenance costs and reduces the user experience.
[0004] Therefore, there is an urgent need for a lighting fixture splicing and fixing connector with a reasonable structure, stable connection, and good electrical contact to solve the problems of unstable connection, easy loosening and falling off, and poor electrical contact in the existing technology, and to improve the safety and reliability of the lighting system. Summary of the Invention
[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a lamp splicing fixing connector. By designing a fixing connector inside the linear light, the invention solves a number of problems such as unstable snap-fit in the existing technology, thereby improving the reliability and practicality of the linear light connection.
[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: a lamp splicing and fixing connector, a first lamp body, a first terminal at one end of the first lamp body, and a fastener base at the rear of the first terminal;
[0007] The second lamp body has a second terminal at one end, which is fixed to a mounting bracket. The mounting bracket has a fastening part, and the first terminal can be engaged with the second terminal to connect the first lamp body and the second lamp body.
[0008] A locking device includes a first fastener, a second fastener, and a latch. The first fastener is horizontally fixed to the end face of the fastener base. The second fastener is connected to one end of the first fastener via an elastic device and is rotatable around the first fastener. The latch is fixed to one end of the second fastener and is connected to the elastic device. The latch is rotatable along the elastic device under external force and elastic force to engage with the fastening part.
[0009] Compared with existing technologies, the advantages of this utility model are as follows: This application provides a compact, easy-to-install, and stable lamp splicing and fixing connector. By setting a locking structure composed of a first latch, a second latch, a snap fastener, and an elastic device, the mechanical locking mechanism of the snap fastener automatically and firmly connects the two lamp bodies after the lamps are spliced, ensuring good contact between the two live terminals and preventing terminal detachment or poor contact due to improper installation, external pulling, or vibration. This stable connection method significantly reduces line resistance, preventing overheating, arcing, or even lamp extinguishing caused by poor contact, greatly improving the safety and stability of the lamp system. Simultaneously, the snap fastener can tightly lock into the latching part under the action of external force and elastic force, not only preventing misalignment and allowing the linear lights to be completely snapped together, but also, during disassembly, only an external force in the opposite direction needs to be applied to the snap fastener to release it under the action of spring force, greatly improving the efficiency and operability of the entire mechanical device.
[0010] In the aforementioned connector, the elastic device is a torsion spring, which has a protruding part that can be wound around the buckle in a clockwise direction. When the buckle rotates toward the second terminal, the protruding part is compressed, and when the buckle rotates toward the first terminal, the protruding part releases the elastic pressure.
[0011] In the aforementioned connector, the end face of the first fastener is provided with a buffer device. When the second fastener rotates toward the second terminal and engages with the end face of the first fastener, the buffer device is used to buffer the fastening force between the second fastener and the first fastener.
[0012] The aforementioned connector has a screw hole on the end face of the fastening part, and the first fastener is fixedly connected to the fastening part by a fastening screw.
[0013] The aforementioned connector has a through hole in the center of the fastening part, through which the second terminal can pass and engage with the first terminal.
[0014] The aforementioned connector has a locking element at the upper end of the fastening part that bends toward the second terminal, and the buckle can be fastened to the locking element.
[0015] In the aforementioned connector, the fastener base is hollow inside, and the end face of the fastener base is lower than the upper end face of the locking fastener.
[0016] The aforementioned connector has a latch at the rear of the fastener base and a protruding spring piece inside the second lamp body. When the first lamp body and the second lamp body are engaged, the spring piece can engage with the latch.
[0017] The aforementioned connector, including the fastener base and the fastening part, is fixed to the first lamp body and the second lamp body by fasteners.
[0018] The aforementioned connector, specifically the locking device, is made of alloy material. Attached Figure Description

Detailed Implementation
[0024] The embodiments of this utility model are described in detail below. Referring to Figures 1 to 4, the embodiments of this utility model provide a lamp splicing and fixing connector, including: a first lamp body 100, a second lamp body 200, and a locking device 300. One end of the first lamp body 100 is provided with a first terminal 110, and a fastener base 111 is provided behind the first terminal 110. One end of the second lamp body 200 is provided with a second terminal 210, which is fixed to a mounting base 211. The mounting base 211 is provided with a fastening part 212, and the first terminal 110 can be engaged with the second terminal 210 to allow the first lamp body 100 and the second lamp body 200 to be connected together. The second lamp body 200 is connected; the locking device 300 includes a first fastener 310, a second fastener 320 and a buckle 330. The first fastener 310 is horizontally fixed to the end face of the fastener base 111. The second fastener 320 is connected to one end of the first fastener 310 through an elastic device 400 and can rotate around the first fastener 310. The buckle 330 is fixed to one end of the second fastener 320 and is connected to the elastic device 400. The buckle 330 can rotate back and forth along the elastic device 400 under external force and elastic force so that the buckle 330 is engaged with the fastening part 212. This utility model provides a compact, easy-to-install, and stable lamp splicing and fixing connector. It features a locking structure composed of a first latch 310, a second latch 320, a snap fastener 330, and an elastic device 400. Through the mechanical locking mechanism of the snap fastener 300, the two lamp bodies are automatically and securely connected after the lamps are assembled, ensuring good contact between the two live terminals and preventing terminal detachment or poor contact due to improper installation, external pulling, or vibration. This stable connection significantly reduces line resistance, preventing overheating, arcing, or even lamp extinguishing caused by poor contact, greatly improving the safety and stability of the lamp system. Simultaneously, the snap fastener 330 can tightly lock onto the latching part 212 under the action of external force and elastic force, not only preventing misalignment and ensuring complete snap-fit of the linear lights, but also allowing for easy disassembly by applying an external force in the opposite direction to the snap fastener 330 under the action of spring force, greatly improving the efficiency and operability of the entire mechanical device.
[0025] Furthermore, referring to Figures 1 and 4, this utility model does not limit the specific structure of the elastic device 400. Preferably, the elastic device 400 is a torsion spring. The elastic device 400 is provided with an extension 410. The extension 410 can be wound around the buckle 330 in a clockwise direction. When the buckle 330 rotates toward the second terminal 210, the extension 410 is compressed. When the buckle 330 rotates toward the first terminal 110, the extension 410 releases the elastic pressure. The torsion spring, acting as an elastic device 400, not only provides the necessary elasticity to ensure the latch 330 is naturally locked without external force, but also, through the connection between the torsion spring and the latch 330, allows the protruding part 410 on the torsion spring to extend and retract according to the rotation direction of the latch 330. When the latch 330 rotates towards the second terminal 210, the protruding part 410 is compressed and stores energy; when the latch 330 rotates in the opposite direction, the protruding part 410 releases the previously accumulated energy, pushing the latch 330 to automatically reset and tightly fit the fastening part 212, ensuring the stability and reliability of the connector under various environmental conditions. This locking device 300 not only allows for better contact between the two live terminals, preventing them from falling off or loosening during use, and preventing arcing or failure to light up between live terminals, but the tight mechanical connection also prevents poor contact caused by pulling during installation and assembly.
[0026] Of course, this utility model does not limit the specific structure of the buckle 330. Preferably, the buckle 330 is an integrally formed structure, with one end of the buckle 330 fixed to the torsion spring and the other end able to engage with the fastening part 212. Referring to Figure 4, further, the end face of the first fastening piece 310 is provided with a buffer device 311. When the second fastening piece 320 rotates toward the second terminal 210 and engages with the end face of the first fastening piece 310, the buffer device 311 is used to buffer the fastening force between the second fastening piece 320 and the first fastening piece 310. The buffer device 311 plays a crucial buffering role during the contact and engagement of the second fastening piece 320 and the first fastening piece 310, reducing the risk of mechanical damage caused by direct collision or excessive compression. Especially after frequent rotation, this buffering mechanism helps maintain a good fit between the components and prevents accelerated wear or loosening of the parts. Of course, this utility model does not limit the specific structure of the first fastener 310 and the second fastener 320. Preferably, the first fastener 310 has a horizontal structure so that the entire locking device 300 fits snugly against the fastener base 111. The second fastener 320 has an inclined plane. This inclined plane can create a gap between the second fastener 320 and the first fastener 310 when they come into contact, which helps reduce wear between the fasteners. In addition, the tail of the inclined plane is provided with a device that is easy for the operator to operate. This operating part also has an inclined part compared to the first fastener 310, so that the operator has operating space when applying pressure to the second fastener 320, which is convenient for operation. Of course, this application does not limit the structure of the buffer device 311. Preferably, the buffer device 311 is a protruding bump. The buffer device 311 can not only absorb the impact force, but also evenly distribute the fastening force, so that a smoother and more stable contact interface is formed between the two fasteners. This not only improves the overall strength and stability of the connector, but also provides the user with a safer operating experience. For example, in high-altitude working environments, any unnecessary vibration or impact may cause the lighting fixtures to shift or even fall off, while the presence of the buffer device 311 effectively reduces such risks and increases the safety of the system.
[0027] Furthermore, the end face of the fastening part 212 is provided with screw holes, and the first fastening piece 310 is fixedly connected to the fastening part 212 by fastening screws. By providing screw holes on the end face of the fastening part 212 and using fastening screws to fix the first fastening piece 310 to the fastening part 212, this design not only enhances the stability and reliability of the overall structure, but also provides additional adjustment space. When it is necessary to make fine adjustments to the angle or position of the lamp, precise adjustments can be achieved by loosening or tightening the fastening screws, ensuring the stability and flatness of the lamp after installation. In addition, the screw connection method is simple and easy to implement, facilitating on-site construction personnel, and also benefiting subsequent maintenance and repair work, improving the maintainability of the lamp system. Furthermore, the fastening part 212 is provided with a through hole 213 in the center, through which the second terminal 210 can pass and engage with the first terminal 110. Providing a through hole 213 in the center of the fastening part 212, allowing the second terminal 210 to pass through and directly engage with the first terminal 110, optimizes the electrical connection and simplifies the assembly process. The presence of the through-hole 213 makes the electrical connection more intuitive and simple, reducing unnecessary intermediate steps, lowering contact resistance, and improving current transmission efficiency. Furthermore, this direct-through connection method ensures tight contact between the two live terminals, preventing arcing or overheating due to poor contact, thus improving the safety performance and lifespan of the luminaire. Further, the upper end of the fastening part 212 has a locking element 214 bent towards the second terminal 210, to which the latch 330 can engage. The locking element 214, bent towards the second terminal 210, provides a clear locking target for the latch 330, increasing the accuracy and success rate of its action. When the latch 330 engages with the locking element 214, the mechanical locking relationship significantly enhances the safety factor of the connection, preventing loosening or detachment due to accidental external forces. This design is particularly suitable for applications requiring high stability, such as outdoor lighting and industrial plants, effectively ensuring the long-term reliability of the luminaire system. Furthermore, the fastener base 111 is hollow inside, and its end face is lower than the upper end face of the locking fastener 214. The hollow design of the fastener base 111 saves material costs and reduces the overall weight. The layout design not only improves assembly efficiency but also provides more operating space for subsequent maintenance, making it easier to disassemble and replace damaged parts and extending the product's service life.
[0028] Furthermore, referring to Figure 3, a latch 112 is provided at the rear of the fastener base 111, and a protruding spring piece 113 is provided inside the second lamp body 200. When the first lamp body 100 and the second lamp body 200 are engaged, the spring piece 113 can be engaged within the latch 112. The latch 112 at the rear of the fastener base 111 and the protruding spring piece 113 inside the second lamp body 200 cooperate to form a physical double locking mechanism. When the first lamp body 100 and the second lamp body 200 are engaged, the spring piece 113 automatically engages within the latch 112, further strengthening the physical connection strength between the lamp bodies and improving the overall structure's pull-out resistance and seismic performance. This design is particularly suitable for applications that need to withstand large external stresses. Furthermore, both the fastener base 111 and the fastening part 212 are fixed to the first lamp body 100 and the second lamp body 200 by fasteners. This design ensures the robustness and consistency of the connections between the components. The fastener fixing method is simple, reliable, and easy to operate, while also facilitating subsequent inspection and maintenance. This method effectively disperses various external stresses applied to the lighting fixture, preventing structural damage caused by localized stress concentration. Furthermore, the fasteners can be selected based on different application environments (such as temperature variations and humidity conditions) to adapt to different usage requirements, thereby further improving the durability and applicability of the lighting system. Of course, this invention does not limit the specific material used for the locking device 300; preferably, the locking device 300 is made of alloy material. Alloy materials possess excellent corrosion resistance and oxidation resistance, and their coefficient of thermal expansion is superior to ordinary plastics or some metal materials, allowing them to maintain good fitting accuracy and connection performance even in environments with large temperature variations. This avoids loosening or jamming caused by uneven material expansion due to temperature differences, improving the environmental adaptability and operational stability of the entire lighting system.
