Description

Technical Field

[0001] The utility model relates to the field of lamp accessories, and particularly relates to a universal power connector for track lights. Background Art

[0002] At present, with the development of the modern architectural decoration industry, track lights have been widely used in commercial spaces, exhibitions, and home decoration due to their easy installation, high flexibility, and easy adjustment. The track light system usually consists of one or more tracks and multiple adjustable-angle lamps installed thereon. The lamps can move freely along the track and be positioned to meet different lighting needs.

[0003] In the existing track light system, the power connector is a crucial component, which is responsible for connecting the lamp to the power supply to ensure the safety and effectiveness of power transmission. However, there are some obvious defects in the connection method and structural design of traditional track light power connectors.

[0004] Currently, the common ways of connecting the internal and external wires of the track light power connectors on the market mainly include the push-type, screw connection, and terminal plugging and unplugging methods. The push-type connection method is easy to operate, but since it requires more wires for electrical connection and generally needs to cooperate with more conductive elastic pieces to achieve, it results in a larger volume of the power connector. In addition, the push-type connection may cause poor contact due to loosening after long-term use, affecting the normal operation of the lamp. The screw connection method is a relatively traditional method for fixing wires. It tightens the screws to clamp the wires to ensure the reliability of electrical connection. However, this method requires a large space to accommodate the screws and other fixing components, also making it difficult to reduce the volume of the power connector. Moreover, tools are required for installation and disassembly, increasing the complexity of the operation. The terminal plugging and unplugging connection is a way to quickly plug and unplug wires through special terminals. Although this method improves the installation efficiency, due to the large size of the terminals themselves and the supporting structures, it also limits the miniaturization development of the power connector. In addition, frequent plugging and unplugging may cause wear to the terminals, affecting the service life.

[0005] The power connectors in the prior art all have a common problem. They have complex structures, complex connection relationships, and numerous components. Therefore, they all require a relatively large internal space to arrange wires, elastic pieces, connection mechanisms, etc. This not only increases the overall volume of the power connector but also limits its applicability in different application scenarios to a certain extent. Especially when it is necessary to install lamps in a limited space, these traditional connection methods obviously cannot meet the requirements.

[0006] Therefore, how to overcome the above-mentioned defects has become an important issue that needs to be urgently solved by those skilled in the art. Summary of the Utility Model

[0007] The utility model overcomes the deficiencies of the above technologies and provides a universal power supply connector for a guide rail lamp.

[0011] Further, the wiring terminal includes a first conductive elastic sheet, and a wiring channel with a wider upper part and a narrower lower part is formed on the first conductive elastic sheet. A wire clamping hole communicated with the wiring channel is arranged at the end of the wiring channel.

[0012] Further, the pressing plate is provided with a positioning structure and a pressing and fixing structure for facilitating the connection of a wire to the quick plug-in wiring module.

[0013] Further, the positioning structure includes a guiding groove formed by concave downward on the upper wall surface of the pressing plate. The pressing and fixing structure includes a wire pressing channel which is arranged opposite to the guiding groove. A convex strip is arranged on the pressing plate in a protruding manner, and a cross beam is detachably connected to the convex strip. The wire pressing channel is formed between the convex strip and the cross beam.

[0014] Further, the rotary switch assembly includes a knob outer cover and a rotating shaft integrally formed with the knob outer cover and rotating synchronously. The rotating shaft is connected to the lower end of the knob outer cover. The axis of the rotating shaft is located at the central position of the knob outer cover. Second conductive elastic sheets, connecting pieces and third conductive elastic sheets are symmetrically arranged on the rotating shaft. The connecting piece is arranged above the second conductive elastic sheet, and the third conductive elastic sheet is arranged above the connecting piece. The third conductive elastic sheet is electrically connected to the quick plug-in wiring module.

[0015] Further, the knob outer cover is hollow inside. A limiting piece extends horizontally inwards from the inner wall surface of the knob outer cover. The limiting piece is integrally formed with the knob outer cover and rotates synchronously therewith. The rotating shaft is connected to the lower end of the limiting piece. Two first connection columns are symmetrically arranged on the guide rail connection seat. When the knob outer cover is rotated, the movement range of the limiting piece is restricted between the two first connection columns.

[0016] Further, the guide rail connection seat includes a guide rail end and a connection end. Connection holes for facilitating the connection of the rotating shaft to an external track are formed on both sides of the guide rail end. When the knob outer cover is rotated, the second conductive elastic pieces and the connection pieces at both ends of the rotating shaft can extend out of the connection holes and be fixedly connected to the external track. Elastic buckles are arranged on both sides of the guide rail end. A first through hole is formed on the connection end. The rotating shaft passes through the first through hole and is rotatably connected to the inside of the guide rail end.

[0017] Further, the first connection columns are arranged on the connection end. Second connection columns extending downwards are provided on the upper cover and inserted into the first connection columns. Second through holes for the second connection columns to pass through are formed on the pressing plate. First screws are installed in the first connection columns. After the first screws penetrate upwards into the first connection columns, they are connected to the second connection columns. Installation holes are formed on the upper cover.

[0018] Further, the guide rail connection seat includes a first shell and a second shell that are detachably connected.

[0019] Compared with the prior art, the beneficial effects of the present utility model are:

[0020] Through a unique structural design, the components of this case are connected in an orderly manner from bottom to top. Among them, the rotary switch assembly is rotatably connected to the guide rail connector, and its lower end extends into the guide rail connector and is electrically connected to the quick plug-in wiring module. This compact design reduces the occupation of unnecessary internal space and avoids the large operating space required by traditional switches. The rotary switch assembly is fixed in place by a pressure plate, reducing unnecessary moving space, which helps to reduce the height of the power connector in this case. The upper cover passes through the pressure plate downward and is fixedly connected to the guide rail connector, pressing the pressure plate tightly. The upper cover not only protects the internal components from external interference but also ensures the compact arrangement of all components through its fixed connection with the guide rail connector. The design of the upper cover closes the top of the entire power connector, avoiding the additional space that may be required in traditional designs to protect the internal components, thus compressing the overall height. The quick plug-in wiring module passes upward through the rotary switch assembly and the pressure plate from the guide rail connector and is exposed at the upper end of the pressure plate. By integrating the quick plug-in wiring module, the guide rail connector reduces the large number of wires and connectors required in traditional designs, effectively reducing the height and width. The quick plug-in wiring module provided in this case allows the wires of the lamp to be directly inserted for quick plugging without welding, bolt fixing, or other complex operations. The design of the quick plug-in wiring module avoids the large number of wires and connectors required in traditional wiring methods, reduces the space required for internal wiring, and thus significantly reduces the volume of the power connector.

[0029] The features of the present utility model and other related features are further described in detail through the following embodiments for the convenience of those skilled in the same industry to understand:

[0030] As Figures 1 to 8 shown, this case provides a general-purpose power connector for a track light, including a track connection base 1, a rotary switch assembly 2, a pressing plate 3, and an upper cover 4 arranged in sequence from bottom to top. The track connection base 1, as the basic part of the power connector, is responsible for physically connecting with the track 200 and providing a necessary support structure. The rotary switch assembly 2 is rotatably connected to the track connection base 1 to facilitate the user to complete the connection between the power connector and the track 200 through a rotating action. The pressing plate 3 covers the upper end of the rotary switch assembly 2, and the upper cover 4 passes through the pressing plate 3 downward and is fixedly connected to the track connection base 1 to press the pressing plate 3 tightly. The pressing plate 3 is located above the rotary switch assembly 2, playing a role in fixing and protecting the upper-end structure and components of the track connection base 1, and also helping to keep the position of the internal components between the track connection base 1 and the pressing plate 3 stable. A quick plug-in wiring module 5 is arranged on the track connection base 1 and penetrates upward through the rotary switch assembly 2 and the pressing plate 3 in sequence and is exposed at the upper end of the pressing plate 3. The lower end of the rotary switch assembly 2 extends into the track connection base 1 and is electrically connected to the quick plug-in wiring module 5, forming an electrical connection with the quick plug-in wiring module 5 to ensure the reliability and safety of power transmission. The design of the quick plug-in wiring module 5 simplifies the wiring process, reduces the space occupied by internal wires, and helps to reduce the overall volume of the power connector. The power connector of this case, through a unique structural design and the cooperation of the above-mentioned components with each other, reduces the overall volume of the power connector of this case. By setting the quick plug-in wiring module 5, the wiring process is simplified, the wiring structure is reduced, and a lot of internal wires are reduced, thus saving internal space and being beneficial to the reduction of the overall volume. Specifically in implementation, the wires of the lamp can be inserted through the upper cover 4 and directly connected to the quick plug-in wiring module 5. The power connector provided in this case adopts the quick plug-in wiring module 5, without the need to connect wires by welding or bolt connection, nor the need to use redundant connectors to connect wires. Instead, it directly adopts the method of quick plugging of wires, without the need for additional tools or complex steps, improving the convenience of installation, while making the structure simpler, the volume smaller, the usability stronger, and the space utilization rate higher. In this way, the power connector of this case can not only be applicable to straight tracks Figure 7 , but also applicable to arc tracks Figure 8 , thereby enhancing its versatility and practicality.

[0031] Continue to refer to Figure 1 , Figure 2 , Figure 5As shown in the figure, specifically, the quick plug-in wiring module 5 of this case includes a fixed seat 51 that is upwardly disposed on the guide rail connection seat 1 and exposed above the upper end of the pressing plate 3, and a wiring terminal 52 fixedly installed on the fixed seat 51. The fixed seat 51 is integrally formed with the guide rail connection seat 1. The setting of the fixed seat 51 provides an installation platform for the wiring terminal 52. Its structural design is compact. It can be vertically installed on the guide rail connection seat 1 and extend upward above the pressing plate 3, reducing the space occupied in the horizontal direction and helping to reduce the overall volume of the power connector. The fixed seat 51 not only supports the wiring terminal 52 but also ensures its stable fixation inside the power connector, preventing displacement caused by vibration or external forces. The wiring terminal 52 is provided for connecting the wires of the lamp. In specific implementation, at least two fixed seats 51 are provided, and correspondingly at least two wiring terminals 52 are provided. The lower ends of the wiring terminals 52 are electrically connected to the rotary switch assembly 2 to achieve the electrical connection between the lamp and the guide rail 200 through the rotation of the rotary switch assembly 2. In specific implementation, in order to ensure safety and reliability, preferably, three fixed seats 51 and wiring terminals 52 are respectively provided correspondingly to be used for connecting the neutral wire, the live wire, and the ground wire. Such a design not only meets the basic requirements of electrical connection but also improves the safety performance of the power connector.

[0032] Further, as Figure 1 , Figure 2 , Figure 5As shown, the terminal 52 includes a first conductive elastic piece 521. In specific implementation, the first conductive elastic piece 521 is made of a metal material with good elasticity and good conductivity, and can withstand repeated deformation without losing elasticity. A wiring channel 522 that is wider at the top and narrower at the bottom is formed on the first conductive elastic piece 521 to facilitate the insertion of the wire from above. Due to the elastic material of the first conductive elastic piece 521, the wiring channel 522 will open under the action of external force when the wire is inserted, thereby allowing the wire to pass through smoothly. Through the design of being wider at the top and narrower at the bottom, it is ensured that the wire can be inserted smoothly, and at the same time, the elastic restoring force is used to clamp the wire, reducing the need for additional fixing components. A wire clamping hole 523 communicating with the wiring channel 522 is provided at the end of the wiring channel 522. The wire clamping hole 523 is used to finally fix the wire. When the wire is pressed into the wire clamping hole, the first conductive elastic piece 521 that elastically resets will clamp the wire. The design of the wire clamping hole 523 enables the wire to be firmly fixed after insertion, avoiding the need for additional fixing devices in the traditional wiring method, thereby reducing the occupation of internal space. In specific implementation, the user can set wiring channels 522 with different shapes, such as conical, trapezoidal, etc., according to needs to adapt to different specifications of wires and improve the insertion experience. The user can also add a multi-stage clamping structure based on the wire clamping hole 523 to adapt to wires with different diameters and improve compatibility. In specific implementation, the user can perform special treatment on the surface of the wiring channel 522, such as plating or coating, to increase wear resistance and corrosion resistance, stabilize the connection between the wire and the wiring channel 522, and extend the service life of the wiring channel 522. When needed, the user can also design the wiring channel 522 to be adjustable to facilitate the user to adjust the opening size of the wiring channel 522 according to needs to adapt to wires with different thicknesses.

[0033] As Figure 1 , Figure 3 , Figure 5 shown, a positioning structure and a pressing and fixing structure for facilitating the connection of wires to the quick plug-in wiring module 5 are provided on the pressing plate 3. The setting of the positioning structure facilitates the accurate and quick installation of the wire. The setting of the pressing and fixing structure facilitates the fixing of the wire and prevents loosening. Specifically, continue to refer to as Figure 1 , Figure 3 , Figure 5As shown, the positioning structure includes a guiding groove 31 formed by concaving the upper wall surface of the pressing plate 3. The guiding groove 31 is used to guide the wire to be correctly inserted into the wiring channel 522 in the quick plug-in wiring module 5, ensuring that the wire is accurately aligned with the wire clamping hole 523. The design of the guiding groove 31 enables the wire to be quickly aligned, simplifies the installation process, and reduces the possibility of installation errors. At the same time, the concavely arranged guiding groove 31 is beneficial to reducing the space where the wire is exposed outside the pressing plate 3, facilitating orderly wiring operations, and on the one hand, reducing the occupation of the internal space. Specifically, the number of the guiding grooves 31 is set to two, which are respectively used to connect the neutral wire and the live wire. The user can set color coding or graphic marks at the notch or side of the guiding groove 31 to help the user more easily identify and correctly install the wire. The pressing and fixing structure includes a wire pressing channel 32, and the wire pressing channel 32 is arranged opposite to the guiding groove 31. The wire pressing channel 32 is used to fix the wire on the wiring terminal 52 after the wire is inserted, preventing the wire from loosening, ensuring that the wire is firmly fixed after insertion, and avoiding power supply connection failure caused by wire loosening. The pressing plate 3 is provided with a convex strip 33 protruding upward, and a cross beam 34 is detachably connected to the convex strip 33. The wire pressing channel 32 is formed between the convex strip 33 and the cross beam 34. Specifically, the cross beam 34 is connected and fixed to the convex strip 33 by bolts. After the wire is connected, the cross beam 34 is threadedly connected to the convex strip 33, and through the fixing action of the cross beam 34, the wire is pressed in the wire pressing channel 32 to fix the wire and prevent it from loosening. Of course, the user can also adopt a snap connection, a magnetic attraction connection or other quick connection methods to replace the bolt connection between the cross beam 34 and the convex strip 33 for easy quick disassembly and adjustment.

[0034] As Figures 1 - 6As shown, further, the rotary switch assembly 2 includes a knob outer cover 21 and a rotating shaft 22 integrally formed with and synchronously rotating with the knob outer cover 21. The user can rotate the knob outer cover 21 to connect the power connector to the guide rail 200. The rotating shaft 22 is connected to the lower end of the knob outer cover 21, and the axis of the rotating shaft 22 is located at the central position of the knob outer cover 21. The integrally formed design of the knob outer cover 21 and the rotating shaft 22 enables the knob outer cover 21 and the rotating shaft 22 to rotate synchronously, reducing additional rotating mechanisms, simplifying the structure, helping to reduce the volume of the power connector, and at the same time facilitating mold opening for production and manufacturing, saving production costs. Symmetrically arranged on the rotating shaft 22 are a second conductive elastic piece 221, a connecting piece 222, and a third conductive elastic piece 223. The connecting piece 222 is arranged above the second conductive elastic piece 221, and the third conductive elastic piece 223 is arranged above the connecting piece 222. The third conductive elastic piece 223 is electrically connected to the quick plug-in wiring module 5. The second conductive elastic piece 221 is provided for electrical connection with the guide rail 200. The connecting piece 222 is provided as a connecting member with the guide rail 200 to make the power connector of this case firmly connected to the guide rail 200. In specific implementation, the lower end of the third conductive elastic piece 223 extends into the guide rail connecting seat 1 and always remains in contact with the first conductive piece 521 to achieve electrical connection between the two.

[0035] Refer to Figure 1 、 Figure 4 、 Figure 5 As shown, further, the knob outer cover 21 is hollow inside to facilitate its structural mating connection with the pressing plate 3 and the guide rail connecting seat 1. A limiting piece 23 extends horizontally inward from the inner wall surface of the knob outer cover 21. The limiting piece 23 is integrally formed with and synchronously rotates with the knob outer cover 21. The rotating shaft 22 is connected to the lower end of the limiting piece 23. Two first connecting columns 11 are symmetrically arranged on the guide rail connecting seat 1. When the knob outer cover 21 is rotated, the movement range of the limiting piece 23 is restricted between the two first connecting columns 11. The limiting piece 23 is used to limit the rotation range of the knob outer cover 21 to ensure that it will not rotate excessively and damage the internal components or the internal structure of the guide rail 200. The first connecting column 11 is used to limit the rotation range of the limiting piece 23 to ensure that the rotation of the knob outer cover 21 will not exceed the set angle. In specific implementation, the user can change the shape of the limiting piece 23 according to needs to achieve the effect of adjusting the rotation angle of the knob outer cover 21.

[0036] Further, as Figure 1 、 Figure 2 、 Figure 5 、 Figure 6As shown, the guide rail connector 1 includes a guide rail end 101 for embedding in the guide rail 200 and a connection end 102 for connecting other components of the power supply connector, such as the pressure plate 3, the rotary switch assembly 2, and the upper cover 4. For convenient production and manufacturing and to ensure the structural stability, the guide rail end 101 and the connection end 102 are integrally formed. Connection holes 1011 are provided on both sides of the guide rail end 101 to facilitate the connection of the rotating shaft 22 to the external track 200. When the knob housing 21 is rotated, the second conductive elastic pieces 221 and the connection pieces 222 at both ends of the rotating shaft 22 can extend out of the connection holes 1011 and be fixedly connected to the external track 200, realizing the electrical connection and the fixed connection with the guide rail. Elastic buckles 1012 are provided on both sides of the guide rail end 101 to further stabilize the connection between the power supply connector and the guide rail 200. A first through hole 13 is provided on the connection end 102, and the rotating shaft 22 passes through the first through hole 13 and is rotatably connected to the inside of the guide rail end 101. Through the design of the first through hole 13, the space occupied by the connection between the rotating shaft 22 and the guide rail connector 1 is reduced.

[0037] As Figures 1 - 6 shown, specifically, the first connection post 11 is provided on the connection end 102, the second connection post 41 extending downward is provided on the upper cover 4 and inserted into the first connection post 11, a second through hole 35 for the second connection post 41 to pass through is provided on the pressure plate 3, a first screw 111 is installed in the first connection post 11, and the first screw 111 passes upward through the first connection post 11 and is connected to the second connection post 41. Through the design of the first connection post 11, the second connection post 41, and the first screw 111, the tight fixation of the upper cover 4 and the guide rail connector 1 is ensured, and at the same time, the pressure plate 3 is tightly fixed, guaranteeing the stability of the internal structure. Mounting holes 42 are provided on the upper cover 4, and the mounting holes 42 are used to connect external lamps and allow the wires of the lamps to pass through and be electrically connected to the power supply connector of this case.

[0038] As Figure 1 、 Figure 6As shown, in this embodiment, to facilitate the installation of components on the rail connector 1, the connection between the rail connector 1 and the rotary switch assembly 2, the pressure plate 3, and the upper cover 4, and to facilitate the installation of wires on the quick plug-in wiring module 5. The rail connector 1 is provided as a first housing 103 and a second housing 104 that are detachably connected, and after the first housing 103 and the second housing 104 are snap-fitted, they are fixedly connected by a second screw 12. Specifically, the first housing 103 and the second housing 104 divide the rail end 101 and the connection end 102 into two parts respectively, that is to say, the rail connector 1 is divided into left and right two parts along the middle of the rail connector 1 in the longitudinal direction. This structure facilitates assembly and subsequent maintenance. The rotating shaft 22 includes a detachable side cover 224. By providing a detachable side cover 224, it is convenient to install the second conductive elastic sheet 221 and the third conductive elastic sheet 223 in the rotating shaft 22, which facilitates assembly and subsequent maintenance. An indication mark 88 is provided on the outer wall surface of the knob outer cover 21 and / or the outer wall surface of the connection end 102. In specific implementation, the indication mark 88 may include a direction arrow mark, a in-place mark, a switch mark, etc., to help the user connect the power connector of this case to the rail 200 more quickly and accurately by rotating the knob outer cover 21. The upper cover 4, the knob outer cover 21, and the connection end 102 are circular in shape. The circular design simplifies the appearance structure compared with the rectangular or square design, which helps to reduce the volume of the power connector. At the same time, it reduces the space occupied during the connection with the rail 200, and the connection operation with the rail 200 is also more convenient.
