Description

Technical Field

[0001] This utility model belongs to the field of UV lamp tube connector technology, specifically relating to a UV lamp tube connector installation device. Background Technology

[0002] UV lamps, also known as ultraviolet lamps, are light sources that emit ultraviolet light. They are widely used in various industrial and civilian fields, such as air and water disinfection, photocuring processes, and fluorescence detection. To ensure the normal and stable operation of UV lamps, they are usually equipped with electrode pins at both ends for electrical connection to the power supply line.

[0003] In existing technologies, the electrode pins at one end of a UV lamp tube are often assembled with a connector via a threaded structure. For example, a common structure involves creating an external thread on the electrode head and screwing it into the corresponding connector to achieve a connection. While this method can ensure a certain degree of contact tightness, it still has shortcomings in terms of structural compactness and ease of assembly and disassembly.

[0004] For example, the existing utility model patent CN205606461U, entitled "A UV Lampshade," describes a structure comprising a lampshade housing, a ceramic connector, and a lamp base mounting device. After the lamp base is inserted into the mounting device, an electrical connection is established via a pipe interface and a connecting piece. This structure simplifies the installation process to some extent, improves replacement efficiency, and offers advantages such as low cost and long lifespan. However, its connection method lacks an effective limiting and locking mechanism, leading to a potential risk of loosening between the lamp base and the mounting device.

[0005] In practical applications, if the UV lamp ends are not properly locked and restrained after being inserted into the power connection device, the lamp pins are prone to loosening or poor contact under long-term operation, vibration, or thermal expansion and contraction. This affects the power supply stability of the UV lamp, reduces its efficiency, and may even cause the lamp to fail. Furthermore, the existing insertion structure has low guiding accuracy, and the pins are prone to misalignment during insertion, increasing installation difficulty and hindering automation or rapid replacement operations. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a UV lamp connector installation device that has a limit locking function, is easy to install and operate, provides accurate insertion guidance, and can achieve a stable electrical connection, thereby solving the problems of loose lamp feet, poor power connection, and low installation efficiency in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A UV lamp tube connector installation device includes a UV lamp tube body and an electrical connector housing. A connector is fixedly provided at one end of the UV lamp tube body, and a socket is fixedly provided at the other end of the connector. A pin at the end of the UV lamp tube body is fixedly fixed to the socket, and a through hole is horizontally provided on the pin. One end of the electrical connector housing is open, and a terminal is fixed on the other end face of the electrical connector housing. An electrical connector sleeve is horizontally fixed inside the electrical connector housing and is electrically connected to the terminal. A guide hole is horizontally provided on the outer wall of the electrical connector housing, and a locking member is horizontally slidably inserted into the guide hole. The locking member is used to lock the connecting electrical connector sleeve and the pin.

[0009] Furthermore, the locking component includes a guide post, which is horizontally slidably inserted into the guide hole of the electrical housing, and a copper post is horizontally fixed at the inner end of the guide post.

[0010] Furthermore, the copper pillar is inserted into the electrical sleeve through the through hole on the pin.

[0011] Furthermore, a spring is horizontally sleeved on the outer side of the guide post, and the two ends of the spring are fixed to the end of the guide post and the outer wall of the electrical contact shell, respectively.

[0012] Furthermore, multiple elastic frames are fixed on both vertical ends of the socket, and grooves are provided on the multiple elastic frames.

[0013] Furthermore, multiple pressure posts are evenly arranged on the lower side of the inner wall of the electrical junction shell, and the multiple pressure posts are fixed on the inner wall of the electrical junction shell.

[0014] Furthermore, the pressure post presses against the groove in the elastic frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention achieves a stable electrical connection after the UV lamp tube is inserted by setting a connector and socket at one end of the UV lamp tube body, and passing the pins inside the socket through the through holes. This, together with the power receiving sleeve and locking component inside the power receiving shell, forms an insertion and locking structure. This structure avoids the problem of pin misalignment or incomplete insertion caused by inaccurate guidance during the insertion process of existing UV lamp tubes, thus improving installation accuracy and ease of operation.

[0017] By setting guide holes on the outer wall of the electrical junction shell and horizontally inserting guide posts, and using copper posts inserted through pin holes to form an electrical connection with the electrical junction sleeve, a spring is fitted on the guide posts to achieve an automatic reset function, enabling automatic positioning and stable locking during the locking process. Compared to the existing structure where the lack of a limiting device causes the lamp pins to loosen easily, this design significantly improves the mechanical stability and long-term operational safety of the lamp tube connector.

[0018] Elastic frames are installed on both sides of the socket, and a corresponding pressure-retaining column structure is arranged on the lower inner wall of the junction box. During insertion into the junction box, the elastic fit creates a limiting and pressure effect, preventing displacement and loosening of the socket due to vibration or prolonged use, thus ensuring the overall stability of the UV lamp after installation. This structure effectively solves the problem of traditional UV lamps lacking structural limiting and insertion security, extending equipment lifespan and improving maintenance and replacement efficiency.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] refer to Figures 1-5As shown, a UV lamp tube connector installation device includes a UV lamp tube body 1 and an electrical connection shell 2. A connector 11 is fixedly installed at one end of the UV lamp tube body 1, serving as the connection base between the UV lamp tube body 1 and a socket 12. An axial channel is pre-reserved inside the connector 11 to accommodate pins 14. A socket 12 is fixedly installed at the other end of the connector 11. The socket 12 has a hollow structure for external insertion into the electrical connection shell 2 to achieve electrical connection. Pins 14 at the end of the UV lamp tube body 1 are fixedly inserted into the socket 12. Pins 14 are made of highly conductive metal material and are molded to the socket 12 using in-mold injection molding. A horizontal through hole is provided on the pin 14. One end of the electrical connection shell 2 is open to facilitate insertion of the socket 12 into its cavity. The other end of the electrical connection shell 2... A terminal block 21 is fixed on the surface. The terminal block 21 is used for electrical connection with the power supply line. The terminal block 21 is connected to the external power supply through threaded fastening terminals or welding. An electrical sleeve 22 is horizontally fixed inside the electrical housing 2. The electrical sleeve 22 is made of elastic conductive copper. Its position is aligned with the pin 14 for insertion. The electrical sleeve 22 is electrically connected to the terminal block 21. A guide hole 24 is horizontally opened through the outer wall of the electrical housing 2. The axial dimension of the guide hole 24 matches the guide post 252, so that the guide post 252 can slide freely in the guide hole. A locking member 25 is horizontally slidably inserted through the guide hole 24. The locking member 25 includes multiple parts that cooperate to form a complete insertion and locking system. The locking member 25 is used to lock the connection between the electrical sleeve 22 and the pin 14 to achieve stable locking after insertion and positioning.

[0028] refer to Figure 4 and Figure 5 As shown, the locking component 25 includes a guide post 252, which is horizontally slidably inserted into the guide hole 24 of the electrical housing 2. The guide post 252 has an overall columnar structure and is injection molded from wear-resistant high-strength engineering plastic. A lubrication groove is provided between its sliding guide surface and the guide hole 24 to improve the smoothness of sliding. A copper post 251 is horizontally fixed at the inner end of the guide post 252. The copper post 251 is installed in the end groove of the guide post 252 by nesting or riveting to ensure that the copper post 251 is pushed synchronously to achieve the insertion and removal operation when the guide post 252 slides.

[0029] refer to Figure 4 and Figure 5 As shown, the copper pillar 251 is inserted into the electrical sleeve 22 through the through hole on the pin 14. The copper pillar 251 is made of highly conductive brass and its front end is tapered to guide and position it during insertion. After insertion, the outer surface of the copper pillar 251 fits tightly against the inner wall of the electrical sleeve 22, thereby forming a stable electrical connection. Through this structure, the UV lamp tube can not only be accurately guided during the insertion process, but also ensure that the electrical connection position is effectively locked after the through hole is passed through, preventing loosening and falling off.

[0030] refer to Figure 4 and Figure 5As shown, a spring 253 is horizontally sleeved on the outer side of the guide post 252. The two ends of the spring 253 are fixed to the end of the guide post 252 and the outer wall of the electrical housing 2, respectively. The spring 253 is made of galvanized steel wire and has good resilience and fatigue resistance. In its compressed state, it stores energy to provide the thrust for the automatic reset of the locking component. With the cooperation of this spring structure, after the guide post 252 is released by external force, it can be quickly reset under the action of elastic force, and the copper post 251 can be reinserted into the through hole of the pin 14 to realize the automatic locking function, which improves the safety and convenience of assembly.

[0031] refer to Figure 3 As shown, multiple elastic frames 13 are fixed on both vertical end faces of the socket 12. The elastic frames 13 are metal spring sheet structures, which are made of stainless steel material and are installed on the vertical side wall of the socket 12 by spot welding or riveting. The multiple elastic frames 13 are provided with grooves. The grooves are used to provide positioning points for abutting against the positioning structure on the inner wall of the electrical housing 2, ensuring that the socket 12 is effectively limited in both the axial and radial directions after being inserted into the electrical housing 2, thereby avoiding displacement under vibration conditions.

[0032] refer to Figure 3 and Figure 4 As shown, multiple pressure posts 23 are evenly arranged on the lower inner wall of the power receiving shell 2. The pressure posts 23 have a raised structure and are arranged in a manner corresponding to the number and position of the elastic frame 13. The pressure posts 23 are fixed on the inner wall of the power receiving shell 2. The pressure posts 23 are integrally formed from plastic engineering material, and their ends are provided with arc-shaped raised surfaces, which facilitates sliding and snapping into the groove of the elastic frame 13 during the insertion process, realizing automatic snap-fit ​​positioning and thus enhancing the vibration resistance of the UV lamp tube after installation.

[0033] refer to Figure 3 As shown, the pressing post 23 presses against the groove of the elastic frame 13; after the pressing post 23 is inserted into the groove of the elastic frame 13, it forms a clamping force under the elastic rebound action of the groove edge. This structure uses elastic fit to realize the physical limiting connection between the UV lamp tube and the electrical shell, and further improves the overall mechanical stability and repeated service life of the device without affecting the electrical connection, overcoming the problem of loose UV lamp tube insertion in the prior art.

[0034] The working principle of this utility model is as follows: During use, a pin 14 at one end of the UV lamp tube body 1 is integrated with the connector 11 and socket 12. During installation, the terminal 21 at one end of the power housing 2 is electrically connected to the power supply line. When assembling the UV lamp tube body 1 and the power housing 2, the locking member 25 in the guide hole 24 of the power housing 2 is pulled, causing the guide post 252 to move laterally within the guide hole 24, compressing the spring 253 and causing the copper post 251 to be pulled out of the through hole on the pin 14. Then, the U... The socket 12 at the end of the UV lamp tube body 1 is inserted into the power receiving shell 2. The pin 14 is inserted into the power receiving sleeve 22 inside the power receiving shell 2. When the guide post 252 is released, under the deformation force of the spring 253, the copper post 251 at the end of the guide post 252 is pushed through the through hole on the pin 14 and inserted into the power receiving sleeve 22, thus completing the insertion and assembly of the socket 12 at the end of the UV lamp tube body 1 and the power receiving shell 2. The presence of the locking part 25 ensures the stability of the insertion and locking of the socket 12 and the power receiving shell 2.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
