Description

Technical Field

[0001] The present invention belongs to the technical field of linear lights, and particularly relates to a splicing and fixing connector for lamps. Background Art

[0002] In modern architectural decoration and lighting projects, modular lamps such as linear lights are widely used due to their aesthetics, flexibility, and ease of installation. In order to achieve continuous splicing and electrical connection between lamps, fixing connectors are usually used to mechanically fix and electrically conduct adjacent lamp bodies. However, most of the existing lamp splicing structures adopt a single spring buckle or snap connection method, which has many deficiencies in actual applications.

[0003] Firstly, traditional connection methods often rely on simple elastic pieces or snaps to fix lamps, resulting in poor connection stability. Especially when subjected to external pulling, vibration, etc. during installation or use, it is very easy for the lamps to loosen or even fall off, affecting the safety and service life of the overall structure. Secondly, there are also obvious defects in the electrical connection of the existing connection structures. The terminals between two lamp bodies do not contact tightly enough, and it is easy to cause poor contact due to improper installation or long-term use, which in turn leads to phenomena such as wire heating, arcing, and even lamp extinguishing, seriously affecting the stable operation of the lamps and even posing potential safety hazards. Especially during the installation and splicing process by workers, if the operation is improper or the lamp wire is pulled forcefully, it is very easy for the terminals to disengage or not be fully engaged, resulting in the lamps being unable to be normally lit or suddenly powering off during operation. This phenomenon not only affects the construction efficiency but also increases the later maintenance cost and reduces the user experience.

[0004] Therefore, there is an urgent need for a splicing and fixing connector for lamps 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 lamp system. Summary of the Invention

[0005] In order to overcome the deficiencies of the existing technology, the purpose of the present invention is to provide a splicing and fixing connector for lamps. By designing a fixing connector inside the linear light, various problems such as unstable snap connection in the existing technology are solved, and the reliability and practicality of the connection of the linear light are improved.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows: A splicing and fixing connector for lamps, a first lamp body, one end of the first lamp body is provided with a first terminal, and a fastener base is provided behind the first terminal;

[0007] A second lamp body, one end of the second lamp body is provided with a second terminal, the second terminal is fixed on a card seat, the card seat is provided with a fastening portion, and the first terminal can be clamped with the second terminal to connect the first lamp body and the second lamp body;

[0008] A locking device, the locking device includes a first buckle piece, a second buckle piece and a buckle. The first buckle piece is horizontally fixed on the end face of the fastener base. The second buckle piece is connected to one end of the first buckle piece through an elastic device, and the second buckle piece can rotate around the first buckle piece. The buckle is fixed to one end of the second buckle piece and the buckle is connected to the elastic device. The buckle can rotate back and forth along the elastic device under an external force and an elastic force to make the buckle clamped on the fastening portion.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides a lamp splicing and fixing connector with a compact structure, convenient installation and stable connection. By setting a locking structure composed of a first buckle piece, a second buckle piece, a buckle and an elastic device, through the mechanical locking mechanism of the locking device, the two lamp bodies are automatically and firmly connected after the lamp splicing is completed, so that good contact is maintained between the two charged terminals, avoiding the disconnection or poor contact of the terminals caused by improper installation, external pulling or vibration. This stable connection method significantly reduces the line resistance, prevents problems such as heating, arcing and even lamp extinguishing caused by poor contact, greatly improves the safety and stability of the lamp system. At the same time, the buckle can be tightly locked on the fastening portion under the action of an external force and an elastic force, which can not only avoid misalignment, but also enable the linear lamp to be completely clamped. Secondly, during the disassembly process, only an external force in the opposite direction needs to be applied to the buckle, and it can be loosened under the action of the spring force, greatly improving the efficiency and operability of the entire mechanical device.

[0010] For the above-mentioned connector, the elastic device is a torsion spring, the torsion spring is provided with an extension portion, the extension portion can be wound around the buckle in the clockwise direction. When the buckle rotates towards the direction of the second terminal, the extension portion is compressed. When the buckle rotates towards the direction of the first terminal, the extension portion releases elastic pressure.

[0011] For the above-mentioned connector, a buffer device is provided on the end face of the first buckle piece. When the second buckle piece rotates towards the direction of the second terminal and is buckled on the end face of the first fastener, the buffer device is used to buffer the fastening force between the second buckle piece and the first buckle piece.

[0012] For the above-mentioned connector, screw holes are provided on the end face of the fastening portion, and the first fastener is fixedly connected to the fastening portion through fastening screws.

[0013] For the above-mentioned connecting member, a through hole is provided in the center of the fastening portion, and the second terminal can pass through the through hole to be snap-connected with the first terminal.

[0014] For the above-mentioned connecting member, the upper end of the fastening portion has a locking member bent in the direction of the second terminal, and the buckle can be buckled to the locking member.

[0015] For the above-mentioned connecting member, the inside of the fastener base is hollow, and the end face of the fastener base is lower than the upper end face of the locking member.

Detailed Description of the Embodiment

[0024] The following details the embodiments of the present invention, referring to Figures 1 to 4, an embodiment of the present invention provides 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, the second terminal 210 is fixed on a card seat 211, and a fastening portion 212 is provided on the card seat 211. The first terminal 110 can be clamped with the second terminal 210 to connect the first lamp body 100 and the second lamp body 200; the locking device 300 includes a first buckle 310, a second buckle 320 and a buckle 330. The first buckle 310 is horizontally fixed on the end face of the fastener base 111. The second buckle 320 is connected to one end of the first buckle 310 through an elastic device 400, and the second buckle 320 can rotate around the first buckle 310. The buckle 330 is fixed to one end of the second buckle 320 and the buckle 330 is connected to the elastic device 400. The buckle 330 can rotate back and forth along the elastic device 400 under an external force and an elastic force so that the buckle 330 is clamped to the fastening portion 212. The present invention provides a lamp splicing and fixing connector with a compact structure, convenient installation and stable connection. By setting a locking structure composed of a first buckle 310, a second buckle 320, a buckle 330 and an elastic device 400, through the mechanical locking mechanism of the locking device 300, after the lamp splicing is completed, the two lamp bodies are automatically and firmly connected, so that good contact is maintained between the two charged terminals, avoiding the disconnection or poor contact of the terminals caused by improper installation, external pulling or vibration. This stable connection method significantly reduces the line resistance, prevents problems such as heating, sparking and even lamp extinguishing caused by poor contact, greatly improves the safety and stability of the lamp system. At the same time, the buckle 330 can be tightly locked to the fastening portion 212 under the action of an external force and an elastic force, which can not only avoid misalignment, but also enable the linear lamp to be completely clamped. Secondly, during the disassembly process, only an external force in the opposite direction needs to be applied to the buckle 330 to achieve loosening under the action of the spring force, greatly improving the efficiency and operability of the entire mechanical device.

[0025] Further, referring to Figure 1 and Figure 4, the present invention does not limit the specific structure of the elastic device 400. Preferably, the elastic device 400 is a torsion spring. An extension portion 410 is provided on the elastic device 400. The extension portion 410 can be wound around the buckle 330 in the clockwise direction. When the buckle 330 rotates towards the second terminal 210, the extension portion 410 is compressed. When the buckle 330 rotates towards the first terminal 110, the extension portion 410 releases the elastic pressure. As the elastic device 400, the torsion spring not only provides the necessary elastic force to ensure the natural locking state of the buckle 330 without external force, but also enables the extension portion 410 on the torsion spring to perform corresponding telescopic actions according to the rotation direction of the buckle 330 through the connection relationship between the torsion spring and the buckle 330. When the buckle 330 rotates towards the second terminal 210, the extension portion 410 is compressed to store energy; when the buckle 330 rotates in the reverse direction, the extension portion 410 releases the previously accumulated energy, pushing the buckle 330 to automatically reset and closely fit the fastening portion 212, ensuring the stability and reliability of the connecting member under various environmental conditions. This locking device 300 not only enables better contact between the two charged terminals, avoids falling off and loosening during use, and prevents problems such as arcing or non-illumination between the charged terminals, but also the tight mechanical connection relationship can prevent the problem of poor contact caused by the separation of the terminals due to pulling during the installation and splicing process by workers.

[0026] Certainly, the present invention does not limit the specific structure of the buckle 330. Preferably, the buckle 330 is an integrally formed structure. One end of the buckle 330 is fixed to the torsion spring, and the other end can be snapped onto the fastening portion 212. Refer to Figure 4, Further, a buffer device 311 is provided on the end face of the first buckle 310. When the second buckle 320 rotates towards the second terminal 210 and is buckled to the end face of the first buckle 310, the buffer device 311 is used to buffer the fastening force between the second buckle 320 and the first buckle 310. The buffer device 311 can play a key buffering role during the process of the second buckle 320 contacting and fitting with the first buckle 310, reducing the risk of mechanical damage caused by direct collision or excessive extrusion. Especially after frequent rotation, this buffering mechanism helps to maintain a good fit between components, preventing increased component wear or loosening. Of course, the present invention does not limit the specific structures of the first buckle 310 and the second buckle 320. Preferably, the first buckle 310 is a horizontal structure so that the entire buckle device 300 fits with the buckle base 111. The second buckle 320 has an inclined plane, and this inclined plane can create a gap between the second buckle 320 and the first buckle 310 when they contact, which helps to reduce wear between the buckles. Additionally, a device that is easy for an operator to toggle is provided at the tail of the inclined plane. This toggling part also has an inclined portion compared with the first buckle 310, leaving an operating space for the operator when applying pressure to the second buckle 320, facilitating operation. Of course, the present 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 impact force but also evenly distribute the fastening force, enabling a smoother and more stable contact interface to be formed between the two buckles. This not only improves the overall strength and stability of the connecting part but also provides a safer operating experience for users. For example, in a high-altitude working environment, any unnecessary vibration or impact may cause the position of the lamp 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, screw holes are provided on the end face of the fastening portion 212, and the first buckle 310 is fixedly connected to the fastening portion 212 through fastening screws. By providing screw holes on the end face of the fastening portion 212 and using fastening screws to fixedly connect the first buckle 310 to the fastening portion 212, this design not only enhances the stability and reliability of the overall structure but also provides additional adjustment space. When fine-tuning the angle or position of the lamp, precise adjustment 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 the operation of on-site construction personnel and also being beneficial for subsequent maintenance and repair work, improving the maintainability of the lamp system. Even further, a through hole 213 is provided in the center of the fastening portion 212, and the second terminal 210 can pass through the through hole 213 to be snap-connected to the first terminal 110. By providing the through hole 213 in the center of the fastening portion 212, allowing the second terminal 210 to pass through and be directly snap-connected to the first terminal 110, this design optimizes the electrical connection while simplifying the assembly process. The presence of the through hole 213 makes the electrical connection more intuitive and simple, reducing unnecessary intermediate links, lowering the contact resistance, and improving the current transmission efficiency. In addition, this direct-through connection method ensures the close contact between the two charged terminals, avoiding arc or heating phenomena caused by poor contact, enhancing the safety performance and service life of the lamp. Furthermore, the upper end of the fastening portion 212 has a locking member 214 bent in the direction of the second terminal 210, and the buckle 330 can be fastened to the locking member 214. The locking member 214 bent in the direction of the second terminal 210 provided at the upper end of the fastening portion 212 provides a clear locking target for the buckle 330, increasing the accuracy and success rate of the operation of the buckle 330. When the buckle 330 is fastened to the locking member 214, the mechanical locking relationship formed between the two significantly enhances the safety factor of the connection, preventing loosening or detachment caused by accidental external forces. This design is particularly suitable for application scenarios requiring high stability, such as outdoor lighting, industrial workshops, etc., effectively ensuring the reliability of the long-term operation of the lamp system. Even further, the inside of the fastener base 111 is hollow, and the end face of the fastener base 111 is lower than the upper end face of the locking member 214. The fastener base 111 adopts a hollow design inside, which not only saves material costs but also reduces the overall weight. This layout design not only improves the assembly efficiency but also provides a larger operating space for subsequent maintenance, facilitating the disassembly and replacement of damaged components, and extending the service life of the product.

[0028] Even further, referring to Figure 3, a bayonet 112 is provided behind the fastener base 111, and a raised elastic piece 113 is provided inside the second lamp body 200. When the first lamp body 100 and the second lamp body 200 are snap-connected, the elastic piece 113 can be snap-connected into the bayonet 112. The bayonet 112 provided behind the fastener base 111 cooperates with the raised elastic piece 113 inside the second lamp body 200 to form a physical double-locking mechanism. When the first lamp body 100 and the second lamp body 200 are snap-connected, the elastic piece 113 automatically snaps into the bayonet 112, further strengthening the physical connection strength between the lamp bodies, improving the tensile and seismic resistance of the overall structure. This design is especially suitable for application scenarios that need to withstand greater external stresses. Further, both the fastener base 111 and the fastening portion 212 are fixed to the first lamp body 100 and the second lamp body 200 through fasteners. This design ensures the firmness and consistency of the connection between components. The fastener fixing method is simple and reliable, easy to operate, and also convenient for later inspection and maintenance. In this way, various stresses applied by the outside world on the lamp can be effectively dispersed, preventing structural damage caused by local stress concentration. In addition, the fasteners can be selected from suitable materials according to different specific application environments (such as temperature changes, humidity conditions, etc.) to adapt to different usage requirements, thereby further enhancing the durability and application range of the lamp system. Of course, the present invention does not limit the specific materials used for the locking device 300. Preferably, the locking device 300 is made of an alloy material. The alloy material has good corrosion resistance and oxidation resistance, and the alloy material is superior to ordinary plastics or some metal materials in terms of controlling the coefficient of thermal expansion, enabling it to still maintain good fitting accuracy and connection performance in an environment with large temperature changes. It avoids connection loosening or jamming phenomena caused by uneven material expansion due to temperature difference changes, improving the environmental adaptability and operation stability of the entire lamp splicing system.
