Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a connector and a splicing lamp. Background Technology

[0002] Interlocking lighting systems, due to their flexible assembly and strong adaptability to various scenarios, have been widely used in commercial exhibitions and home ambient lighting. In this type of system, multiple lamp segments are mechanically joined and electrically connected via connectors to achieve live and neutral wire connections between adjacent lamp segments, which simplifies installation to some extent. However, the current method for connecting the main power supply to interlocking lighting systems is typically as follows: existing connectors are replaced with connectors having more interfaces at any point along the edge of the interlocking structure. External power is then connected through the extra ports, and the power is transmitted to subsequent series-connected lamp segments via internal wiring.

[0003] This power access method has significant limitations in on-site construction: First, when the splicing area is large, if the power socket is located inside the splicing structure and far from the edge, additional wiring is required to connect it to the external power source. This easily leads to messy on-site wiring, especially in dense installation scenarios, significantly increasing the difficulty of wiring management. Second, power is transmitted through wiring inside the lamp tubes, and the cumulative contact resistance increases after multiple segments are connected in series. This may not only cause localized overheating but also reduce the stability of the power supply to the end lamp tubes. In summary, existing technologies lack a connector that can directly integrate power access functionality and simplify wiring. Utility Model Content

[0016] Compared with the prior art, the connector and splicing light provided by this utility model have the following beneficial effects:

[0017] 1. The connector provided in this embodiment of the utility model, by setting a main body, at least two plug-in parts extending from the main body in different directions, and a power access part located between adjacent plug-in parts, and forming an electrical cavity inside the main body, allows the plug-in ports of each plug-in part and the power interface of the power access part to be connected to the electrical cavity, thereby achieving efficient and compact connection between the power supply and multiple load devices, such as lamps. Specifically, a conductive structure can be integrated in the electrical cavity. The external power line is connected to the electrical cavity through the power interface, and then distributed to each plug-in part by the conductive structure set in the electrical cavity. Multiple lamps or other electrical devices can be directly plugged into the corresponding plug-in ports to be powered on, without the need for additional adapter lines, thereby significantly simplifying the entire wiring architecture. This not only saves installation space and reduces cable tangling, but also improves the reliability and safety of the power supply connection, making it particularly suitable for electrical application scenarios with multiple devices and high integration.

[0018] 2. The connector provided in this embodiment of the present invention has at least two conductive elements disposed within its electrical cavity. Each conductive element includes a central connecting portion, a first conductive terminal extending from the central connecting portion into each plug portion, and a second conductive terminal extending from the central connecting portion into a power input portion. This conductive element has a simple structure, enables parallel electrical transmission between multiple plug portions and a power interface, and is easy to assemble.

[0019] 3. In the connector provided in this embodiment of the present invention, the length of the second conductive terminal is greater than that of the first conductive terminal. Since the power input part is located between the two plug-in parts and is far from the center of the electrical cavity, the longer design of the second conductive terminal can ensure a reliable connection of the conductive path from the power interface to the electrical cavity, avoiding poor contact or unstable power supply due to the terminal being too short.

[0020] 4. In the connector provided in this embodiment of the present invention, the extension length of the power input portion relative to the main body is less than the extension length of the plug portion relative to the main body. The smaller extension length of the power input portion allows for a more compact power input section, saving space and preventing excessively long power terminals from occupying unnecessary space, thus preventing interference when the plug portion is connected to external devices. Simultaneously, the larger extension length of the plug portion provides sufficient insertion depth, thereby ensuring good contact and increasing insertion and removal stability.

[0021] 5. The connector provided in this embodiment of the present invention has three plug-in parts, which are evenly distributed radially at 120° with the center of the main body as the center. This ensures that the force borne by each plug-in part is physically balanced, which can effectively prevent mechanical damage or deformation of a plug-in part due to excessive force, and improve the durability and stability of the overall structure.

[0022] 6. The connector provided in this embodiment of the utility model, by providing limiting grooves and steps at the insertion part and the power input part, ensures that the fixing part of the electrical connector is firmly engaged in the limiting groove, avoiding the risk of loosening due to vibration or external force. The protrusion engaged on the step helps to further stabilize the connection and reduce the possibility of poor contact or loose insertion.

[0023] 7. In the connector provided in this embodiment of the utility model, a limiting baffle is provided at the position of the limiting groove on the upper cover. When the upper cover and the lower cover are closed, the limiting baffle abuts against the upper surface of the electrical connector. This can effectively fix the position of the electrical connector and prevent it from shifting or loosening during use, further ensuring the stability of the electrical connection, especially when subjected to external vibration or impact. Furthermore, the limiting baffle can prevent dust and other debris from entering the electrical cavity through the power interface or plug port, ensuring the long-term reliability of the connector.

[0024] 8. The connector provided in this embodiment of the present invention has a snap-fit ​​integrally formed on the plug portion, with the snap-fit ​​hook facing the inside of the plug port. The snap-fit ​​design can lock the light tube or other electrical equipment into the plug portion after insertion, preventing it from falling off and ensuring the stability of power supply.

[0025] 9. In the connector provided in this embodiment of the present invention, the inner wall of the power interface is provided with a guide groove extending along its insertion direction. The design of the guide groove can prevent power plug errors and also increase the smoothness of insertion and removal.

[0026] 10. This utility model embodiment also provides a splicing lamp, which has the same beneficial effects as the connector described above, and will not be described in detail here. Attached Figure Description

[0044] Please see Figure 1 and Figure 2 The first embodiment of this utility model provides a connector 1 for connecting multiple load devices, such as lamp tubes, etc., including:

[0045] Main body 10, with an electrical cavity 100 formed inside the main body 10;

[0046] At least two plug-in portions 11, each plug-in portion 11 extending in different directions along the main body portion 10, and a plug-in port 110 provided at the end of the plug-in portion 11 away from the main body portion 10, the plug-in port 110 being connected to the electrical cavity 100;

[0047] The power access part 12 protrudes from the main body part 10 and is located between two adjacent plug-in parts 11. The end of the power access part 12 away from the main body part 10 is provided with a power interface 120, which is connected to the electrical cavity 100.

[0048] Understandably, the main body 10 is used to carry and support the plug-in part 11 and the power access part 12, and the internal electrical cavity 100 provides space for electrical connection. The number of plug-in parts 11 is the number of load devices that the connector 1 can connect to. The plug-in port 110 of each plug-in part 11 and the power interface 120 of the power access part 12 are all connected to the electrical cavity 100. External power is introduced through the power socket. Multiple load devices are plugged in through the plug-in port 110, which can realize efficient and compact connection between the power supply and multiple load devices, and provide parallel power supply to multiple load devices connected to the connector 1, solving the problems of messy wiring and unstable power supply when the existing connector 1 is connected to the power supply.

[0049] Specifically, an external power source extends into the electrical cavity 100 and can be directly connected to various load devices. Alternatively, a conductive structure can be integrated within the electrical cavity 100, with the external power source connected to the electrical cavity 100 via the power interface 120. The conductive structure within the electrical cavity 100 then distributes the power to each connector 11. Multiple lamps or other electrical devices can be directly plugged into the corresponding connectors 110 to be powered, without the need for additional adapters. Connector 1 significantly simplifies the wiring architecture during installation, saving installation space, reducing cable tangling, and improving the reliability and safety of the power supply connection. It is particularly suitable for electrical applications with multiple devices and high integration.

[0050] Understandably, placing the power input section 12 between two adjacent plug sections 11 can maximize the use of available space, ensure that the functions of the power input section 12 and the plug section 11 do not interfere with each other, and make the overall layout of the connector 1 more compact.

[0051] Understandably, in this embodiment, the connector 1 forms a conductive part, a plug-in part 11, and a power input part 12 together through a detachably connected upper cover 13 and lower cover 14. The detachable upper cover 13 and lower cover 14 facilitate installation and maintenance.

[0052] Furthermore, the extension length of the power input portion 12 relative to the main body portion 10 is less than the extension length of the plug portion 11 relative to the main body portion 10.

[0053] Understandably, the shorter extension length of the power input portion 12 allows for a more compact design, avoiding unnecessary space occupation by excessively long power terminals, preventing interference when the connector portion 11 is plugged into external devices, and resulting in a cleaner and more aesthetically pleasing appearance for the connector 1. Simultaneously, the longer extension length of the connector portion 11 provides sufficient insertion depth, ensuring that the load device can be stably plugged into the connector portion 11, thereby ensuring good contact and increasing insertion and removal stability.

[0054] Understandably, in this embodiment, the number of plug-in parts 11 is not limited, and each plug-in part 11 can be evenly distributed or unevenly distributed, depending on the specific connection requirements.

[0055] As a specific example, there are three plug-in parts 11, which are evenly distributed radially at 120° with the center of the main body 10 as the center.

[0056] Understandably, the three plug-in parts 11 are evenly distributed radially at 120°, which ensures that the force borne by each plug-in part 11 is balanced in terms of physical structure. This can effectively prevent mechanical damage or deformation of a plug-in part 11 due to excessive force, and improve the durability and stability of the overall structure.

[0057] Please combine further Figure 3 The conductive structure integrated within the electrical cavity 100 specifically comprises at least two conductive elements 101. Each conductive element 101 includes a central connecting portion 102, a first conductive terminal 103 extending from the central connecting portion 102 into each plug-in portion 11, and a second conductive terminal 104 extending from the central connecting portion 102 into the power input portion 12.

[0058] Understandably, the second conductive terminal 104 extends into the power input section 12 to connect to an external power source, transmitting the current flowing into the power input section 12 to the central connection section 102, and then distributing it to each of the first conductive terminals 103 via the central connection section 102. The first conductive terminals 103 supply current to the load devices inserted into the plug-in section 11, enabling a single external power source to simultaneously power multiple load devices connected to the connector 1. This conductive component 101 has a simple structure and is easy to assemble.

[0059] Furthermore, please continue to combine Figure 4 and Figure 5 One of the upper cover 13 or the lower cover 14 is provided with a connecting post 140 facing the electrical cavity 100, and the other is provided with a corresponding connecting post hole 130. When the upper cover 13 and the lower cover 14 are closed, the end of the connecting post 140 is inserted into the connecting post hole 130. An opening 105 is provided on the central connecting part 102 of the conductive element 101, and the conductive element 101 is sleeved on the connecting post 140 through the opening 105.

[0060] Furthermore, the dimensions of each first conductive terminal 103 on the conductive member 101 are the same to distribute the current evenly and provide the same power supply to the load devices plugged into different plug-in portions 11.

[0061] Furthermore, the length of the second conductive terminal 104 is greater than that of the first conductive terminal 103.

[0062] Understandably, since the power input part 12 is located between the two plug-in parts 11 and is far from the center of the electrical cavity 100, the second conductive terminal 104 is designed to be longer to ensure a reliable connection of the conductive path from the power interface 120 to the electrical cavity 100, and to avoid poor contact or unstable power supply due to the terminal being too short.

[0063] Furthermore, combined Figure 2 and Figure 4 The lower cover 14 is provided with limiting grooves 141 corresponding to each plug-in part 11 and power access part 12 facing the electrical cavity 100. Steps 142 are provided on the opposite side walls of the limiting grooves 141. Electrical connectors 15 are provided in both the plug-in part 11 and the power access part 12. The electrical connectors 15 include a fixing part 150 and a connecting part 151. The fixing part 150 is snapped into the limiting groove 141. The connecting part 151 is provided with a protrusion 152 along its insertion direction. The protrusion 152 is snapped into the step 142.

[0064] Specifically, the electrical connector 15 has at least two vertically arranged through holes 153 along its insertion direction. Different conductive elements 101 extend into different through holes 153. The ends of the first conductive terminal 103 and the second conductive terminal 104 of the conductive element 101 are hollow cylinders that match the through holes 153. The shape of the electrical connector 15 matches the power plug of the external power plug or the power plug of the load device, so that the power plug of the external power plug or the power plug of the load device can be directly plugged into the electrical connector 15. After plugging in, it is electrically connected to the conductive element 101 extending into the electrical connector 15 to achieve stable power supply.

[0065] Understandably, the limiting groove 141 limits the fixing part 150 of the electrical connector 15, preventing the electrical connector 1 from being misaligned during insertion and avoiding the risk of the electrical connector 1 becoming loose due to vibration or external force. The protrusion 152 engages with the step 142, which helps to further stabilize the connection and reduce the possibility of poor contact or loose insertion.

[0066] Please see Figure 5 Furthermore, the upper cover 13 is provided with a limiting baffle 131 corresponding to the limiting groove 141. When the upper cover 13 and the lower cover 14 are closed, the limiting baffle 131 abuts against the upper surface of the electrical connector 15.

[0067] Understandably, the limiting baffle 131 can further fix the position of the electrical connector 15 to prevent it from shifting or loosening during use, especially when subjected to external vibration or impact, thus ensuring the stability of the electrical connection.

[0068] Optionally, the electrical connectors 1 provided in the plug-in portion 11 and the power input portion 12 can be the same or different; correspondingly, the limiting grooves 141 and limiting baffles 131 on the upper cover 13 and the lower cover 14 can be provided in the same way, or they can be different depending on the different electrical connectors 1.

[0069] Please see Figure 2 Furthermore, the plug portion 11 is integrally provided with a latch 111, the hook 112 of the latch 111 facing the inside of the plug port 110. The design of the latch 111 can lock the load device into the plug portion 11 after it is inserted, preventing it from falling off and ensuring the stability of the connection.

[0070] Furthermore, the inner wall of the power interface 120 is provided with a guide groove 121 extending along its insertion direction.

[0071] Understandably, the design of the guide groove 121 can prevent power plug errors and also increase the smoothness of plugging and unplugging.

[0072] Further, please refer to Figure 4 The lower cover 14 also integrally provides a mounting part 143, on which a mounting hole 144 is provided. The mounting part 143 is flush with the bottom surface of the lower cover 14. The connector 1 can be fixed in its current position by screws or bolts passing through the mounting hole 144, which is more convenient for manufacturing or fixed installation on different objects.

[0073] Please see Figure 6 The second embodiment of this utility model provides a splicing lamp 2, including lamp tubes 20, power cords 21 and the aforementioned connector 1. The end of the lamp tube 20 extends into the plug-in port 110, and the power cord 21 extends into the power interface 120. Multiple lamp tubes 20 and power cords 21 are electrically connected in the electrical cavity 100.

[0074] Understandably, the power input port of the lamp tube 20 is located at its end, and the plug part 11 serves to connect and fix the lamp tube 20, while realizing the electrical connection between the lamp tube 20 and the power line 21 in the electrical cavity 100. The wiring structure of this splicing lamp 2 is simple and clear, and the installation space is large.

[0075] Please see Figure 7 The third embodiment of this utility model provides a splicing light 3, which includes a lamp tube 30, a power cord 31 and multiple connectors 1, thereby forming splicing lights 3 with different shapes and styles.

[0076] It should be noted that, Figure 7 The shape of the splicing light 3 is only a specific example shown to facilitate the explanation of the technical solution of this embodiment, and is not intended to limit the shape, structure or specific form of the splicing light in this utility model.

[0077] Furthermore, depending on the specific connection shape and power supply requirements of the splicing light 3, the lamp tube 30 can be equipped with a power input port at one end or both ends.

[0078] Understandably, depending on the specific power supply requirements of the splicing light 3, one power cord 31 may be inserted into the power interface 120 of a single connector 1, or multiple power cords 31 may be inserted into the power interfaces 120 of multiple connectors 1.

[0079] Understandably, the splicing lights 2 and 3 also have the same beneficial effects as the connector 1 mentioned above, which will not be elaborated here.
