Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connector technology, and in particular to an electrical connector and an illuminated letter. Background Technology
[0002] When installing illuminated signs, illuminated doorplates, and illuminated advertising letters, it is necessary to connect the power lines pre-installed during the lintel decoration to the pre-installed wires on the illuminated letters. During wiring, the outer insulation of two wires needs to be stripped to expose the copper core, then the copper cores are overlapped and fixed, and insulated with insulating tape. However, this wiring method is not only time-consuming and labor-intensive, resulting in numerous and messy wires and inconvenient operation, but also requires a high level of wiring skill from the operator. Utility Model Content
[0003] The main purpose of this utility model is to provide an electrical connector and an illuminated advertising sign, which facilitates wiring and installation by operators, reduces the technical requirements for wiring, and saves labor.
[0004] To achieve the above objectives, this utility model proposes an electrical connector, comprising conductive metal tubes for connecting to positive and negative power lines, conductive components for connecting to positive and negative power lines of an illuminated character, and an insulating component sleeved on the outer surface of the conductive metal tubes. The conductive metal tubes are detachably connected to the conductive components on one side inside the insulating component.
[0005] In one possible implementation, the conductive element includes a conductive post and a plurality of elastic conductive sheets connected to the conductive post. The cross-section of each elastic conductive sheet is arc-shaped. An expansion groove is provided inside the conductive metal tube. The maximum distance between two relative elastic conductive sheets is greater than the width of the expansion groove.
[0006] In one possible implementation, a hemispherical connecting block is also included, each of the elastic conductive sheets includes an arc segment and a horizontal segment connected to one side of the arc segment, each of the horizontal segments is fixedly connected to the interior of the conductive post, and the arc segment of each of the elastic conductive sheets is fixedly connected to the hemispherical connecting block.
[0007] In one possible implementation, the expansion groove has an annular inclined surface that is slidably connected to the outer surface of the arc segment on the side near the elastic conductive sheet.
[0008] In one possible implementation, the outer surface of the conductive post away from the elastic conductive sheet is provided with a threaded section for threaded connection with the illuminated letter, and a limiting ring is provided on the side of the conductive post near the threaded section.
[0009] An illuminated sign is adapted to the aforementioned electrical connector. The illuminated sign includes a housing, and the back of the housing is provided with conductive nuts that are respectively connected to the positive and negative power lines of the illuminated sign. The threaded section is threadedly connected to the conductive nuts.
[0010] This utility model's technical solution, by setting up conductive metal tubes, conductive components, and insulating components, allows decorators to pre-connect two conductive metal tubes to the positive and negative power lines pre-installed on the lintel. When installing illuminated signs, users only need to connect the two conductive components to the positive and negative power lines of the sign, and then directly insert the conductive components into one side of the conductive metal tube inside the insulating component, thus achieving a quick connection between the power lines and the sign's wiring. Compared to traditional methods, there is no need to strip the wire insulation, overlap the copper core, or perform insulation treatment, significantly improving wiring efficiency, reducing operational difficulty, and correspondingly reducing the technical requirements for wiring operators.
[0011] At the same time, connecting the positive and negative power lines of the illuminated sign directly to the conductive components can save on the length of the power line, thereby reducing the cost of the power line. Attached Figure Description

[0020] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0022] Example 1:
[0023] refer to Figure 1-4 This embodiment proposes an electrical connector, including a conductive metal tube 1 for connecting to the positive and negative power lines, a conductive component 2 for connecting to the positive and negative power lines of the illuminated character, and an insulating component 3 sleeved on the outer surface of the conductive metal tube 1. The insulating component 3 can be a plastic plug or an insulating shell, and this embodiment does not impose any restrictions on it.
[0024] Furthermore, one side of the conductive metal tube 1 should be fixedly connected to the inner wall of the insulating component 3, and the conductive metal tube 1 should be detachably connected to the conductive component 2 on one side inside the insulating component 3. By placing the contact area between the conductive metal tube 1 and the conductive component 2 inside the insulating component 3, the insulating component 3 can provide reliable insulation protection, avoiding short circuits caused by external environmental factors (such as moisture, dust, etc.) during use, thus improving the safety and stability of the entire electrical connection system.
[0025] Meanwhile, by hiding the contact parts inside the insulating component 3, the appearance of the electrical connector becomes cleaner and more aesthetically pleasing.
[0026] In use, decorators can pre-connect the positive and negative power lines pre-installed on the lintel to the two conductive metal tubes 1, and insulate them with insulating tape. Simultaneously, the insulating component 3 is inserted into the wall panel 5 (using screws or other installation tools to fix the insulating component 3 to the wall panel 5). When installing the illuminated sign, the user simply connects the two conductive components 2 to the positive and negative power lines of the illuminated sign, then directly inserts the conductive component 2 into one side of the conductive metal tube 1 inside the insulating component 3. Finally, the illuminated sign is fixed to the wall panel 5. This achieves a quick connection between the power line and the illuminated sign's wiring, is convenient, and reduces the technical requirements for wiring.
[0027] More specifically, the conductive component 2 includes a conductive post 201 and several elastic conductive sheets 202 connected to the conductive post 201. The cross-section of each elastic conductive sheet 202 is arc-shaped. An expansion groove 101 is provided inside the conductive metal tube 1. The maximum distance between two relative elastic conductive sheets 202 is greater than the width of the expansion groove 101.
[0028] When the user inserts the conductive element 2 into the expansion groove 101, because the maximum distance between the two elastic conductive sheets 202 is greater than the width of the expansion groove 101, the end face of the expansion groove 101 will squeeze the elastic conductive sheets 202 and cause them to deform as the user pushes them in. When the elastic conductive sheets 202 are fully inserted into the expansion groove 101, because the elastic conductive sheets 202 have the ability to recover their deformation, they will expand outward on the inner wall of the expansion groove 101 and exert force on the side wall of the expansion groove 101, thereby fixing the conductive element 2 in the expansion groove 101 and fixing it to the conductive metal tube 1.
[0029] When disassembly is required, the operator only needs to overcome the force exerted by the elastic conductive sheet 202 on the inner wall of the expansion groove 101 to remove the conductive component 2 from the conductive metal tube 1. This structural design allows the user to simply push the elastic conductive sheet 202 into the expansion groove 101 during installation, and to overcome the force exerted by the elastic conductive sheet 202 on the inner wall of the expansion groove 101 and pull the conductive component 2 outward during disassembly, without any additional complex operations, thus improving practicality. At the same time, the elastic pressure applied by the elastic conductive sheet 202 ensures continuous contact with the inner wall of the expansion groove 101, avoiding poor contact caused by vibration.
[0030] Furthermore, the elastic conductive sheet 202 and the conductive post 201 can be made of beryllium bronze, a material with excellent elastic properties that maintains good elastic recovery after multiple elastic deformations, ensuring reliable elastic contact of the elastic conductive sheet 202 during connection and separation from the conductive metal tube 1. Simultaneously, beryllium bronze has good conductivity, effectively transmitting current and meeting the conductivity requirements of electrical connectors, thus reducing power loss.
[0031] In addition to the connection methods described above, the conductive component 2 can also be threaded into the interior of the conductive metal tube 1 (i.e., the inner wall of the expansion groove 101). During installation, the operator only needs to screw the conductive component 2 into the interior of the conductive metal tube 1; during disassembly, simply rotate the conductive component 2 in the opposite direction to unscrew it from the interior of the conductive metal tube 1.
[0032] Furthermore, it also includes a hemispherical connecting block 2023. Each elastic conductive sheet 202 includes an arc segment 2021 and a horizontal segment 2022 connected to one side of the arc segment 2021. Each horizontal segment 2022 is fixedly connected to the inside of the conductive post 201. The arc segment 2021 of each elastic conductive sheet 202 is fixedly connected to the hemispherical connecting block 2023.
[0033] The hemispherical connecting block 2023 can connect the various elastic conductive sheets 202 into one piece (the hemispherical connecting block 2023 and each elastic conductive sheet 202 can be integrally formed) to improve the overall structural strength. At the same time, the arc surface of the hemispherical connecting block 2023 can prevent scratches on the outer surface of the insulating part 3 due to misalignment when the user pushes the conductive part 2 into the insulating part 3.
[0034] Secondly, an annular inclined surface 1011 is provided on the side of the expansion groove 101 near the elastic conductive sheet 202, which is slidably connected to the outer surface of the arc-shaped segment 2021. This design allows the annular inclined surface 1011 to guide and compress the arc-shaped segment 2021 to smoothly enter when the elastic conductive sheet 202 is inserted into the expansion groove 101, thus playing a guiding role and preventing the elastic conductive sheet 202 from getting stuck or obstructed during insertion. At the same time, the annular inclined surface 1011 can also reduce wear between the elastic conductive sheet 202 and the side of the expansion groove 101, thereby ensuring its reliability and stability during long-term use.
[0035] In this embodiment, a threaded section 2011 for threaded connection with the illuminated character is provided on the outer surface of the conductive post 201 away from the elastic conductive sheet 202. The threaded section 2011 can facilitate the threaded connection of the conductive post 201 with other components, such as the shell 4 of the illuminated character, so as to achieve quick and firm installation and fixation.
[0036] Meanwhile, the threaded connection between the conductive post 201 and the illuminated sign allows the sign to be secured when the user simultaneously inserts the two conductive components 2 into the insulating component 3 inside the wall panel 5. This eliminates the need for users to use screws or other tools for further fixing, simplifying the installation process. Furthermore, since the conductive component 2 is located on the back of the sign, the front of the sign can conceal the mounting components (such as the conductive component 2 and the insulating component 3), resulting in a more aesthetically pleasing and neat appearance after installation. If there are concerns about the sign becoming loose, a ring of adhesive can be applied between the back of the sign and the wall panel to strengthen the bond. For disassembly, use a knife to cut open the hardened adhesive layer and then pull the sign outwards.
[0037] Furthermore, a limiting ring 2012 is provided on the side of the conductive post 201 near the threaded section 2011. When the conductive component 2 is fully inserted into the expansion groove 101, the side of the limiting ring 2012 will contact the side of the insulating component 3, and the other side will contact the housing 4 of the illuminated character, thereby preventing the user from excessively screwing the conductive post 201 into the housing 4 of the illuminated character. At the same time, the limiting ring 2012 can also limit the position of the conductive post 201 during installation, ensuring the accuracy of installation, thereby improving the safety and stability of the electrical connector.
[0038] It is worth noting that the voltage generated when the illuminated letter is lit is usually low. Therefore, the risk of short circuit when the limiting ring 2012 is exposed between the back of the illuminated letter and the insulating component 3 (i.e., exposed to the external environment) is low. If there are concerns about the risk of short circuit, the limiting ring 2012 can be replaced with insulating material to prevent it from being affected by environmental factors and causing a short circuit.
[0039] Example 2:
[0040] refer to Figure 5 This embodiment discloses an illuminated letter that is compatible with the aforementioned electrical connector. Specifically, the illuminated letter includes a housing 4 (made of insulating material). The back of the housing 4 is provided with conductive nuts 401 that are respectively connected to the positive and negative power lines of the illuminated letter. A threaded section 2011 is threadedly connected to the conductive nuts 401, and the conductive nuts 401 are fixedly connected to the housing 4. Furthermore, a receiving groove for installing the conductive nuts 401 can be provided on the back of the housing 4; this will not be elaborated further in this embodiment. During the manufacturing process of the illuminated letter, workers can solder the positive and negative power lines of the illuminated letter to the conductive nuts 401 respectively. This method avoids the need for excessively long power lines, thereby reducing the manufacturing cost of the illuminated letter. It also saves workers time in organizing excess power lines.
[0041] The threaded connection ensures a tight fit between the conductive component 2 and the housing 4, guaranteeing reliable connection. Furthermore, operation is simple, requiring only the rotation of the conductive component 2, further enhancing practicality. Compared to traditional wiring methods, this connection not only simplifies the installation process but also improves connection stability and conductivity, reducing the risk of illuminated sign malfunctions due to poor wiring.
[0042] Working principle:
[0043] 1. Reference Figure 6 The decorators can connect the positive and negative power lines reserved on the lintel to the two conductive metal tubes 1 through terminals, and use insulating tape to insulate them. At the same time, the insulating parts 3 are inserted into the wall panel 5 and fixed.
[0044] 2. Then, screw the threaded sections 2011 on the two conductive parts 2 into the conductive nuts 401 of the positive and negative terminals respectively.
[0045] 3. Finally, the conductive element 2 is directly inserted into the expansion groove 101 and continuously pushed in until the side of the limiting ring 2012 contacts the side of the insulating element 3. During the pushing process, the end face of the expansion groove 101 will squeeze the elastic conductive sheet 202, causing it to deform. When the elastic conductive sheet 202 is fully inserted into the expansion groove 101, due to its ability to recover its deformation, it will expand outward on the inner wall of the expansion groove 101 and exert force on the side wall of the expansion groove 101, thereby fixing the conductive element 2 in the expansion groove 101 and fixing it to the conductive metal tube 1.
