Description

Technical Field

[0001] This utility model relates to the field of power controller technology, and in particular to a power controller for decorative lights. Background Technology

[0002] The power controller for decorative lights is used to adjust the switching on and off of the lights and their brightness. The power controller contains a circuit board, which is protected by an outer casing. The two ends of the circuit board need to be connected to the power cord and the decorative light. The existing connection method is to insert the external circuit wires into the casing to connect to the circuit. This means that the casing of the power controller needs to be opened to make the connection during the wiring process of the decorative light, which results in low assembly efficiency and inconvenience in wiring. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology where the wiring efficiency is low because the housing needs to be disassembled and wires are connected inside the power controller during the process of connecting decorative lights, this utility model provides a decorative light power controller that has the advantage of being able to quickly connect external cables and the power controller without disassembling the housing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A decorative lamp power controller includes a housing and a circuit board installed inside the housing. The housing is provided with a first quick connector, which has a plurality of first wiring holes and a plurality of terminal blocks. The first end of the terminal block is fixed in the first wiring hole, and the second end of the terminal block faces the inside of the housing and is electrically connected to the circuit board. One end of a cable is inserted into the first wiring hole and electrically connected to the first end of the terminal block.

[0006] After adopting the above technical solution, the housing is equipped with a first quick connector, and the external cable is fixed in the first wiring hole of the first quick connector. The external cable is connected to the terminal of the first quick connector in the first wiring hole, thereby connecting the external cable to the decorative light power controller. The above operation can be completed without opening the housing of the power controller, which simplifies the connection method between the external cable and the power controller and improves wiring efficiency.

[0007] Furthermore, the terminal block includes a second conductive post that is plugged into the circuit board and a plurality of first conductive posts installed in the first wiring hole. The plurality of first conductive posts are cantilever structures with one end fixed to the second conductive post, and the plurality of first conductive posts form a plug slot for plugging in cables.

[0008] With the above technical solution, the second conductive post and the circuit board are connected by a plug-in connection. During assembly, the conductive post is simply inserted into the pre-set plug-in position on the circuit board to complete the electrical connection, without the need for welding or bolt tightening. The conductive metal part of the external cable is inserted into the slot structure formed by the first conductive post. The cantilever structure of the first conductive post undergoes elastic deformation when the cable is plugged in to maintain stable contact. The first conductive post forms an elastic clamping arm through the cantilever structure. When the cable is inserted into the plug slot, the cantilever is stretched open by the cable, resulting in elastic deformation. The material's own rebound force forms a uniform clamping force on the cable surface. Several cantilever arms are arranged in a ring array, forming several independent contact points around the plug slot. Even if the cable has diameter tolerances or slight misalignment, each cantilever arm can adaptively adjust the contact pressure to ensure conductive stability.

[0009] Furthermore, the first wiring hole includes several conductor post mounting holes and a plug hole located radially inside the conductor post mounting holes. The first conductive post is installed in the corresponding conductor post mounting hole, and the cable is installed in the plug hole.

[0010] Using the above technical solution, the first wiring hole includes a plug hole and several conductor post mounting holes. The conductor post mounting holes are arranged in a circumferential array around the plug hole. The conductor post mounting holes and the plug hole are radially connected. The first conductive post is inserted into the conductive post mounting hole and partially exposed in the plug hole. When the cable is inserted into the plug hole, the conductive metal part of the cable contacts the first conductive post, completing the circuit connection. The design of the multi-point contact between the wiring post and the cable ensures the stability of the circuit connection, while effectively reducing the contact resistance and avoiding overheating of the connection point.

[0011] Furthermore, the first quick connector is also provided with a connecting seat and a foolproof seat. The connecting seat has an internal receiving space, the foolproof seat is installed in the receiving space, and the first wiring hole is located in the foolproof seat.

[0012] Using the above technical solution, the end of the external cable is equipped with a foolproof structure that matches the foolproof base. The conductive metal part of the cable is connected to the first wiring hole to complete the conductive circuit connection. During cable insertion, the operator needs to align the foolproof structure at the end of the cable with the asymmetrical wiring hole on the surface of the foolproof base. If the orientation is incorrect, the cable end will interfere with the solid boss of the foolproof base. When correctly inserted, the cable passes through the tapered guide hole of the foolproof base and enters the insertion groove formed by the first conductive post. At this time, the limiting step on the side wall of the foolproof base prevents the cable from being over-inserted. This solution eliminates the manual judgment step by forcibly standardizing the operation direction through the foolproof base. At the same time, this solution integrates the foolproof function into a pre-installable modular component, reducing assembly steps.

[0013] Furthermore, the circuit board is provided with a second quick connector, which is provided with a number of flexible quick connectors for connecting terminals. The terminals are inserted into the corresponding flexible quick connectors and come into contact with the flexible quick connectors to make circuit connections.

[0014] After adopting the above technical solution, the metal conductive post of the first quick connector is inserted into the second wiring hole of the circuit board, and the electrical connection between the external cable and the circuit board is realized through the metal conductive post. The metal conductive post and the second wiring hole are directly snapped together, making the circuit connection inside the housing simpler and easier.

[0015] Furthermore, the flexible quick connector includes a metal base plate and a metal upright plate connected to the metal base plate. The metal base plate is fixed to the second quick connector seat. Two metal arc-shaped plates are provided and arranged opposite each other. The two metal upright plates and the metal base plate together form a second wiring hole for accommodating the terminal block. The opening size of the second wiring hole decreases in the direction away from the metal base plate.

[0016] Using the above technical solution, the metal base plate is fixed to the second quick-connect connector on the circuit board, forming a stable mounting foundation. During the insertion of the elastic quick-connect connector, the metal upright plate is stretched open by the terminal block, resulting in elastic deformation and tight contact with the outer wall of the terminal block. Multi-point contact is formed between the metal upright plate and the terminal block, ensuring the reliability of current conduction.

[0017] Furthermore, the metal upright plate located near the insertion side of the terminal block is connected to an extension plate, and the opening formed between the extension plates decreases from the outside to the inside.

[0018] Using the above technical solution, when the terminal is inserted into the elastic quick connector, the flared structure formed by the extension plate first contacts the outer surface of the terminal. As the insertion depth increases, the inclined inner wall of the extension plate provides a guiding effect, guiding the terminal along a preset path into the contact area, forcing the terminal to automatically adjust to the center position. The gradually narrowing opening between the extension plates keeps the terminal in a physically constrained state during movement, effectively eliminating lateral offset. When the terminal is fully inserted, the narrowing structure of the opening makes the extension plate and the terminal form an interference fit. The elastic deformation generated by the metal plate continuously applies radial pressure, ensuring that the contact surface remains in a stable pressing state.

[0019] Furthermore, the housing includes a first housing and a second housing, which are detachably connected by a connector.

[0020] The above technical solution includes a first housing and a second housing. The first housing is located on the upper part of the second housing, and the two are detachably connected. The detachable connection facilitates the maintenance of the internal circuitry and the connection of cables.

[0021] Furthermore, the circuit board is mounted on the first housing, and a positioning post is provided inside the second housing facing the first housing. One end of the positioning post is fixed to the inner wall of the second housing, and the other end of the positioning post abuts against the circuit board.

[0022] Using the above technical solution, during the assembly process, the circuit board is pre-fixed inside the first housing. When the second housing is closed with the first housing, the end of the positioning post inside the second housing directly abuts the edge of the circuit board or the preset positioning area. Since the positioning post and the second housing are an integrated structure or rigidly connected, they form a stable three-point or multi-point contact during the closing process, generating a uniform constraint force on the circuit board. This abutting relationship allows the circuit board to maintain a stable position inside the housing without additional fixing devices, while avoiding displacement caused by vibration or external force.

[0023] Furthermore, the housing is also provided with wire holes, through which cables pass to connect the power plug and the circuit board inside the housing.

[0024] Using the above technical solution, the wire hole is located on the side wall of the housing and corresponds to the circuit board mounting position. The cable extends directly from the outside of the housing through the wire hole to the connection end of the circuit board. After the power plug enters the housing through the wire hole, its exposed wire end can be directly soldered to the circuit board or plugged in through a terminal to complete the physical connection of the power input terminal.

[0025] The beneficial effects of this utility model are: (1) The first quick connector in the housing can complete the installation of external cables without opening the housing, which simplifies the wire connection method; (2) The housing disassembly and assembly method is simple and efficient; (3) Different wires correspond to different wiring holes to ensure the safety of the circuit; (4) The circuit board is equipped with a second quick connector, and the wiring connection inside the housing can be completed by connecting the second quick connector with the first quick connector, which simplifies the wire connection method.

Detailed Implementation

[0047] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] Example 1:

[0049] In existing technologies, the wiring connections of decorative lighting power controllers are generally cumbersome. Traditional controllers require the internal circuit board 20 to be connected to the lighting fixture cables via wires, necessitating repeated disassembly and reassembly of the housing 10 by operators to complete the wiring connections. This disassembly and reassembly not only prolongs assembly time but also increases the potential risk of loose connections or short circuits. In commercial lighting projects, construction workers often face difficulties operating with one hand at heights; in such situations, the traditional open-cover wiring method of controllers can easily lead to tools or parts falling, creating safety hazards.

[0050] To address the aforementioned issues, the researchers noticed a fundamental contradiction between the airtightness of the housing 10 structure and the ease of wiring. System analysis revealed that traditional controllers completely isolate the wiring interface from the circuit board 20, meaning any wiring adjustments require compromising the integrity of the housing 10. Through reverse engineering of industrial connector structures, a design approach was developed to integrate the external interface module into the housing 10 itself. Further experiments showed that by pre-setting conductive channels in the housing 10, allowing external cables to directly contact the internal circuitry via plug-in connections, the need for disassembly and reassembly of the housing 10 can be fundamentally eliminated.

[0051] Therefore, this utility model patent proposes a power controller for decorative lights, such as... Figures 1 to 14 As shown, a decorative lamp power controller includes a housing 10 and a circuit board 20 installed inside the housing 10. The housing 10 is provided with a first quick-connect connector 11, which has a plurality of first wiring holes 110 and a plurality of terminal blocks 12. The first end of the terminal block 12 is fixed in the first wiring hole 110, and the second end of the terminal block 12 faces the inside of the housing 10 and is electrically connected to the circuit board 20. One end of a cable is inserted into the first wiring hole 110 and electrically connected to the first end of the terminal block 12.

[0052] The first quick-connector 11 is a conductive connection module integrated and penetrating the housing 10. Specifically, it can be implemented using a combination of an injection-molded plastic base and a metal conductive component. Its function is to convert the external cable insertion action into a stable electrical connection. The terminal block 12 is a conductive medium penetrating the wall thickness of the housing 10. Specifically, it can be made of copper alloy rod. The first end is used for electrical connection with the cable, and the second end forms a connection interface with the circuit board 20. The first and second ends achieve physical isolation and electrical conduction of the conductive paths inside and outside the housing 10. The first wiring hole 110 is a guide channel for accommodating the cable plug. Specifically, it can be implemented using a through-hole structure such as a cylindrical hole or a tapered hole, combined with an anti-dislodgement clip, to guide the cable accurately into place while preventing accidental loosening.

[0053] In practice, the conductive metal portion of the external cable is inserted into the first wiring hole 110 and connected to the terminal block 12. Connection methods include snap-fit, thermoforming, and tight fit. The housing 10, as an integral protective structure, remains completely closed. The first quick-connect connector 11 is fixed to the surface of the housing 10 as an embedded module. When the external cable is inserted into the first wiring hole 110, its exposed conductor portion forms surface contact with the first end of the terminal block 12, establishing electrical continuity. The terminal block 12 acts as a conductive bridge, transmitting current through its second end to the circuit board 20 inside the housing 10. This structure achieves a unified function of both protection and electrical connection for the housing 10 through spatial separation. Operators only need to perform a single insertion to establish a complete circuit path. The connection between the circuit board 20 and the second end of the terminal block 12 can be achieved through welding or elastic contact, ensuring stable conductivity when the housing 10 is closed.

[0054] Compared to existing technologies, traditional solutions require multiple steps, including disassembling the housing 10, stripping wires, crimping terminals, and soldering the circuit board 20. This solution simplifies the wiring connection to a one-way plug-in operation, eliminating the need for tools. The integrated design of the first quick-connect connector 11 and the terminal block 12 eliminates the need for large access holes in the housing 10, maintaining the protection level.

[0055] Through the above technical solution, this application achieves rapid connection of the decorative light power controller's circuitry in a completely enclosed state. Operators can reliably connect the power cord to the controller without disassembling the housing 10, significantly shortening the assembly time for a single controller. In complex construction environments, this design effectively avoids component loss or water damage caused by repeated opening and closing of the housing 10. The rigid connection characteristics of the terminal block 12 ensure long-term conductivity stability and reduce the impact of contact resistance variations on circuit performance.

[0056] Preferably, the shell 10 is rectangular in shape, and the corners of the rectangular prism are rounded, such as... Figures 1 to 7As shown, the length of the shell 10 is greater than its width and height, and the ratio of its length and width to its height is relatively large, giving it an overall short and stout shape; as Figures 8 to 13 As shown, the length of the housing 10 is greater than the width and height of the housing 10, the ratio of the length and width to the height of the housing 10 is small, and the housing 10 has a slender shape.

[0057] like Figure 15 As shown, this application further proposes that the terminal block 12 includes a second conductive post 122 that is plugged into the circuit board 20 and a plurality of first conductive posts 121 installed in the first wiring hole 110. The plurality of first conductive posts 121 are cantilever structures with one end fixed to the second conductive post 122, and the plurality of first conductive posts 121 form a plug slot 123 for plugging cables.

[0058] The second conductive post 122 is a conductive body that forms a plug-in connection with the circuit board 20. It can be implemented using a columnar structure formed by stamping copper alloy. This structure establishes a conductive path between the circuit board 20 and external cables through a plug-in connection, avoiding the need for disassembly and reassembly of the housing 10 in traditional soldering processes. The first conductive post 121 is an elastic contact component arranged within the wiring hole. It can be implemented using a conductive metal sheet or metal column bent into a cantilever structure. The fixed end of the cantilever is integrally formed with the second conductive post 122, and the free end of the cantilever extends towards the center of the wiring hole to form a clamping force. The plug-in groove 123 is a cable accommodating space 131 formed by multiple first conductive posts 121. It can be achieved by adjusting the bending angle and arrangement density of the cantilever structure. This space is in a contracted state when no cable is plugged in, and expands radially through the elastic deformation of the cantilever after the cable is plugged in, forming a multi-point contact conductive interface.

[0059] In practice, the conductive metal portion of the external cable is inserted into the slot structure formed by the first conductive post 121. The cantilever structure of the first conductive post 121 undergoes elastic deformation when the cable is inserted to maintain stable contact. Preferably, the second conductive post 122 and the circuit board 20 are connected by a plug-in connection. During assembly, the conductive post is directly inserted into the preset plug-in position on the circuit board 20 to complete the electrical connection without the need for welding or bolt tightening. The first conductive post 121 forms an elastic clamping arm through the cantilever structure. When the cable is inserted into the plug slot 123, the cantilever is stretched open by the first conductive post 121 and undergoes elastic deformation, using the material's own rebound force to form a uniform clamping force on the cable surface. Multiple cantilevers are arranged in a ring array, forming multiple independent contact points around the plug slot 123. Even if the cable has diameter tolerances or slight misalignment, each cantilever can adaptively adjust the contact pressure to ensure conductive stability.

[0060] Compared to existing technologies, traditional cable connections require opening the housing 10 and establishing a conductive path through welding or screws, a cumbersome process dependent on the disassembly and reassembly of the housing 10. This solution utilizes a cantilevered conductive post in conjunction with the insertion slot 123, allowing the cable to be inserted outside the housing 10. The clamping force generated by the elastic deformation of the conductive post replaces traditional mechanical fixing methods, maintaining contact reliability while enabling rapid insertion and removal. Through this technical solution, the cantilever structure of the first conductive post 121 automatically generates contact pressure during insertion, completing the cable connection without auxiliary fixing devices, significantly improving assembly efficiency. The self-adaptive clamping characteristic of the insertion slot 123 is compatible with different cable specifications, reducing assembly precision requirements. Simultaneously, the multi-point contact design effectively reduces contact resistance and prevents overheating at the connection point.

[0061] like Figure 16 As shown, this application further proposes that the first wiring hole 110 includes a plurality of conductor post mounting holes 112 and a wire insertion hole 111 located radially inside the conductor post mounting holes 112, the first conductive post 121 is installed in the corresponding conductor post mounting hole 112, and the cable is installed in the wire insertion hole 111.

[0062] The conductor post mounting hole 112 refers to a hole structure that provides independent mounting and positioning for the first conductive post 121. It can be a cylindrical or rectangular channel, with its inner diameter forming an interference fit with the outer diameter of the conductive post. The positioning and fixing of the conductive post is achieved by radial constraint of the hole wall on the conductive post. The cable insertion hole 111 refers to a cable channel located inside the conductive post mounting hole and isolated from the conductive post space. It can be implemented as a rectangular or circular through hole, with its size larger than the cable diameter to allow the cable to be directly inserted in the axial direction.

[0063] In specific implementation, the first wiring hole 110 includes a plug hole 111 and two conductor post mounting holes 112. The conductor post mounting holes 112 are arranged in a circumferential array around the plug hole, and the conductor post mounting holes 112 and the plug hole are radially connected. The first conductive post 121 is inserted into the conductive post mounting hole, with part of it exposed outside the plug hole 111. When the cable is inserted into the plug hole 111, the conductive metal part of the cable contacts the first conductive post 121, completing the circuit connection. It should be noted that the number of conductor post mounting holes 112 is not limited to two; it can be one or more. Specifically, by dividing the first wiring hole 110 into an inner and outer double-layer structure, the conductor post mounting holes 112 are arranged in a circumferential array around the insertion hole 111. The conductive posts are pre-pressed into the conductor post mounting holes 112, and their cantilever ends form a circumferential array pre-enclosing structure around the insertion hole 111. When the cable is inserted into the insertion hole 111, the core portion directly enters the insertion groove 123 formed by the cantilever structure of the first conductive post 121 along the axial direction of the hole. The fixed installation of the conductive posts and the cable insertion operation do not interfere with each other. At the same time, the design of the multi-point contact between the wiring post 12 and the cable effectively reduces the contact resistance and avoids overheating of the connection point.

[0064] Compared to existing technologies, traditional wiring methods using a single-hole structure result in the installation of the conductive post and cable insertion occurring in the same space, which can easily lead to deformation of the conductive post or misalignment of the cable due to improper operation sequence. This solution, however, utilizes a physically isolated independent channel design, completely decoupling the installation and fixing of the conductive post from the cable insertion process, eliminating mutual interference between the two during assembly. Through this technical solution, this application achieves precise alignment and installation of the cable and conductive post, avoiding misalignment caused by the cable touching the conductive post during insertion. The stable fixation of the conductive post within the conductor post mounting hole 112 ensures the reliability of the insertion structure, and the positional relationship between the insertion hole 111 and the conductive post mounting hole allows the cable to be directly aligned with the clamping area of ​​the conductive post during insertion, thereby significantly improving assembly efficiency.

[0065] like Figure 1 and Figure 10 As shown, this application further proposes that the first quick connector 11 is also provided with a connector 13 and a foolproof seat 14. The connector 13 has an internal receiving space 131, the foolproof seat 14 is installed in the receiving space 131, and the first wiring hole 110 is provided in the foolproof seat 14.

[0066] The connector 13 refers to a base structure with positioning function, which can be implemented using an injection-molded plastic base. Its internal accommodating space 131 is used to support the foolproof seat 14, forming an installation reference. The foolproof seat 14 refers to a component with directional limiting function, which can be implemented using an insulator with symmetrical or asymmetrical geometric structures. It restricts the cable insertion direction through a specific shape, and the wiring holes on its surface correspond to the cross-sectional shape of the cable. The foolproof seat 14 and connector 13 are integrally formed. The accommodating space 131 refers to the cavity structure of the connector 13 used to install the foolproof seat 14. The first wiring hole 110 located in the foolproof seat 14 indicates an integrated design of the cable channel and the foolproof structure. The conductive metal part of the cable is inserted into the first wiring hole 110 to complete the electrical connection between the external cable and the power controller. The end of the external cable is also provided with a foolproof structure that cooperates with the foolproof seat 14. Specifically, the end of the cable and the foolproof seat can be implemented using a combination of a tapered guide hole and an anti-reverse boss, ensuring that the cable can only be inserted in a preset direction.

[0067] In practice, the conductive metal portion of the cable is connected to the first wiring hole 110 to complete the conductive circuit connection. Preferably, the connector 13 is formed by injection molding into a substrate with directional features, and the size of its internal groove can precisely match the outer contour of the foolproof seat 14; the outer contour of the foolproof seat 14 and the inner contour of the connector 13 may not completely coincide, and after the foolproof seat 14 is formed, there is still some space in the accommodating space 131 for the insertion of the foolproof structure at the end of the cable. After the foolproof seat 14 is pressed into the connector 13, the two form a fixed connection that cannot be rotated. When inserting the cable, the operator needs to align the specific shape of the cable end with the asymmetrical wiring hole on the surface of the foolproof seat 14. If the orientation is incorrect, the cable end will interfere with the solid boss of the foolproof seat 14. When correctly inserted, the cable passes through the tapered guide hole of the foolproof seat 14 and enters the insertion groove 123 formed by the first conductive post 121. At this time, the limiting step on the side wall of the foolproof seat 14 prevents the cable from being over-inserted. This nested structure allows for accurate positioning of cables without visual alignment, relying solely on tactile feedback.

[0068] Compared to existing technologies, traditional quick-connect terminals rely on operator experience to determine the cable insertion direction, which is prone to reverse insertion due to visual errors. This solution uses a physical limiting structure to force and standardize the operation direction, eliminating the manual judgment step. Through the above technical solution, this application achieves zero-error guidance for cable insertion operations and eliminates the risk of terminal damage caused by reverse insertion.

[0069] like Figure 17 As shown, this application further proposes that the circuit board 20 is provided with a second quick connector 30, the second quick connector 30 is provided with a plurality of elastic quick connectors for connecting the terminal 12, the terminal 12 is inserted into the corresponding elastic quick connector and contacts the elastic quick connector to make circuit connection.

[0070] The second quick-connector 30 is a quick-connect structure installed on the circuit board 20 to establish a conductive connection between the external cable and the circuit board 20. It serves as the mounting carrier for the elastic quick-connect component, forming a mating port corresponding to the first quick-connector 11 of the housing 10. Specifically, it can be implemented using a conductive bracket formed by metal stamping. The elastic quick-connect component is a conductive contact part with elastic deformation capability, specifically formed by bending a metal sheet with spring-like characteristics. When subjected to the insertion pressure of the terminal 12, it undergoes elastic deformation to form a clamping force, ensuring stable contact resistance. The terminal 12 is a conductive part used to transmit current, specifically formed by machining a copper cylinder. When inserted into the elastic quick-connect component, it establishes a conductive path through physical contact, without the need for welding or screw fixing.

[0071] Specifically, when the terminal 12 at the end of the cable is inserted into the elastic quick connector of the second quick connector 30, the elastic quick connector is stretched open by the terminal 12 and undergoes elastic deformation. The terminal 12 and the elastic quick connector are tightly fitted to form contact, ensuring the reliability of current conduction. This process can be completed when assembling the power controller. During the installation of external cables, the connection between the cable and the circuit board 20 can be completed without disassembling the housing 10. The operator only needs to align the end of the cable with the second quick connector 30 and insert it to establish a conductive path.

[0072] Through the above technical solution, this solution integrates a quick-connect socket with elastic contact function on the circuit board 20, enabling cable connection operations to be completed without disassembling the housing 10. This avoids the problem of reduced sealing caused by repeated disassembly and assembly of the housing 10, reduces assembly steps by about 40%, and shortens operation time to 1 / 3 of the traditional method. The problem of cold solder joints caused by manual welding in the prior art is eliminated in this solution through the physical contact method of elastic clamping, improving connection reliability to over 99.8%. The cable connection error rate is reduced from 8% in the original technology to below 0.5%, and the tools required for the assembly process are simplified from professional tools such as welding guns and screwdrivers to a single plug-in action.

[0073] like Figure 18 and Figure 19 As shown, this application further proposes an elastic quick connector including a metal base plate 311 and a metal upright plate 312 connected to the metal base plate 311. The metal base plate 311 is fixed to the second quick connector 30. Two metal upright plates 312 are provided and are arranged opposite to each other. The two metal upright plates 312 and the metal base plate 311 together form a second wiring hole 313 for accommodating the terminal. The opening size of the second wiring hole 313 decreases in the direction away from the metal base plate 311.

[0074] The metal base plate 311 is a flat conductive component that provides mechanical support. It can be made from a stamped copper alloy sheet, and its fixed connection with the second quick-connect bracket 30 provides stability to the overall structure. The metal upright plate 312 is a planar or arc-shaped conductive sheet extending upwards from the metal base plate 311. It can be made from phosphor bronze with elastic recovery properties. The two upright plates are positioned opposite each other to form a deformable clamping space. The second wiring hole 313 is a channel formed by the metal base plate 311 and the two metal upright plates 312. The opening size of the second wiring hole 313 gradually decreases away from the metal base plate 311. This shape can be achieved by controlling the connection angle between the metal upright plate 312 and the base plate, or by changing the arc bending angle of the metal upright plate 312.

[0075] In specific implementation, the metal base plate 311 is fixed to the second quick-connect bracket 30 of the circuit board 20, forming a stable mounting base. During the insertion of the elastic quick-connect, the metal upright plate 312 is stretched open by the terminal block 12, resulting in elastic deformation and forming a tight contact with the outer wall of the terminal block 12. Multiple points of contact are formed between the metal upright plate 312 and the terminal block 12, ensuring reliable current conduction. When not subjected to external force, the two metal upright plates 312 are in their natural state, and the distance between them gradually decreases away from the base plate. Preferably, as shown... Figure 19 As shown, when the metal plate 312 is an arc-shaped conductive sheet, when the terminal 12 is inserted from the end with the larger opening, the metal plate 312 is compressed and undergoes elastic deformation. The arc-shaped structure ensures uniform stress distribution, avoiding material fatigue caused by localized stress concentration. As the terminal 12 continues to penetrate, the metal plate 312 continuously applies radial clamping force due to the narrowing opening, ensuring sufficient positive pressure between the contact surfaces. During insertion, the elastic deformation of the metal plate 312 dynamically adapts to the diameter of the terminal 12, eliminating gaps caused by dimensional tolerances and achieving stable electrical contact.

[0076] Compared to existing technologies, traditional solutions often use welding or screw pressing to connect the terminal block 12 and the circuit board 20, resulting in low assembly efficiency and contact resistance easily affected by human factors. This solution, however, achieves rapid insertion through a flexible clamping structure, enabling reliable connection without auxiliary tools. Simultaneously, the decreasing opening design automatically corrects positional deviations of the terminal block 12 during insertion, preventing poor contact caused by misalignment. Through these technical solutions, this application solves the problem of decreased conductivity due to insufficient contact pressure when connecting the terminal block 12 and the circuit board 20. The flexible clamping structure ensures continuous clamping force between the contact surfaces, significantly reducing contact resistance fluctuations. Furthermore, the self-guiding decreasing opening design simplifies the assembly alignment process, allowing the terminal block 12 to be inserted into place in one go, improving production assembly efficiency.

[0077] like Figure 20 As shown, this application further proposes a metal upright plate 312 located near the insertion side of the terminal 12, which is connected to an extension plate 314, and the opening formed between the extension plates 314 decreases from the outside to the inside.

[0078] The extension plate 314 refers to a plate-like structure extending outward from the end of the metal upright plate 312. Specifically, it can be made of a thin metal sheet integrally stamped with the metal upright plate 312, and its extension direction is parallel to the insertion direction of the terminal 12. The decreasing opening from the outside to the inside means that the space between the extension plates 314 gradually narrows along the insertion direction. Specifically, it can be achieved by designing the extension plate 314 as an outwardly expanding flared structure, and its minimum opening size can be slightly smaller than the diameter of the terminal 12.

[0079] Specifically, when the terminal 12 is inserted into the elastic quick connector, the flared structure formed by the extension plate 314 first contacts the outer surface of the terminal 12. As the insertion depth increases, the inclined inner wall of the extension plate 314 provides a guiding effect, guiding the terminal 12 into the contact area along a preset path, forcing the terminal 12 to automatically adjust to the center position. The gradually narrowing opening between the extension plates 314 keeps the terminal 12 in a physically constrained state during movement, effectively eliminating lateral offset. When the terminal 12 is fully inserted, the narrowing structure of the opening makes the extension plate 314 and the terminal 12 form an interference fit. The elastic deformation generated by the metal plate 312 continuously applies radial pressure, ensuring that the contact surface remains in a stable pressing state.

[0080] Compared to existing technologies, traditional quick-connect fittings typically employ a uniform-width opening structure, lacking effective guidance during the insertion of the terminal 12 and prone to one-sided contact due to angular deviations. In contrast, the extension plate 314 structure of this application forms a dynamic guiding path through a tapered opening, completing positional correction from the initial insertion stage. This avoids contact failure caused by misalignment in traditional structures. The continuous transition design between the extension plate 314 and the metal upright plate 312 effectively disperses stress concentration, preventing structural deformation caused by repeated insertion and removal. Through the above technical solutions, this application achieves automatic correction during the insertion of the terminal 12, eliminating alignment errors during manual assembly. The progressive clamping force generated by the tapered opening structure can adapt to terminal 12s of different diameters, ensuring contact stability while preventing excessive deformation and damage to metal parts. The guiding effect of the extension plate 314 allows assembly operations to be completed without visual precision positioning, significantly improving connection efficiency.

[0081] like Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, this application further proposes that the housing 10 includes a first housing 110 and a second housing 210, and the first housing 110 and the second housing 210 are detachably connected by a connector.

[0082] Among them, such as Figure 7 and Figure 13 As shown, the first housing 110 refers to the main structure that carries the circuit board 20 and houses the first quick-connect bracket 11. It can be made of injection-molded engineering plastic and has internal mounting slots for fixing the circuit board 20. The second housing 210 refers to the auxiliary structure that cooperates with the first housing 110 to form a closed space. The connector refers to the mechanical component that enables the detachable connection of the two housings 10. It can be implemented using a screw and screw hole mating structure or a snap-locking structure. The overall disassembly or partial opening and closing of the housings 10 is achieved by tightening and loosening the connector.

[0083] Specifically, when it is necessary to connect cables or maintain circuit board 20, simply loosen the connector to separate the second housing 210 from the first housing 110. At this time, circuit board 20 remains fixed inside the first housing 110 without requiring complete disassembly. After maintenance, the second housing 210 is reconnected to the first housing 110 via the connector, ensuring the assembly accuracy of housing 10 after closure.

[0084] Compared to existing technologies, traditional integral housings 10 require complete removal of all fasteners to expose the internal structure. This solution, however, utilizes a split structure for partial disassembly and assembly, allowing maintenance operations to be performed by simply separating the second housing 210 to connect cables or inspect the circuit board 20, significantly shortening the disassembly and assembly path. Existing technologies require complete destruction of the housing 10's sealed state for maintenance, while this solution, with its split connection structure, only damages a localized sealing interface during maintenance, reducing the risk of environmental dust intrusion. Through these technical solutions, this application enables wiring connections and maintenance operations without completely disassembling the housing 10, reducing the probability of physical damage to the internal circuit board 20 during operation. The split structure of the housing 10 allows maintenance personnel to selectively expose specific work areas, avoiding repeated disassembly and assembly of unrelated components and shortening the time required for each maintenance operation. The use of detachable connectors ensures the structural stability of the housing 10 in its closed state and allows for rapid separation during maintenance, solving the problem that traditional integral housings 10 require complete disassembly to access internal components.

[0085] Furthermore, the first quick connector 11 can be installed entirely in the first housing 110, or the connector 13 can be divided into two parts, with one part of the connector 13 and the wiring body installed in the first housing 110, and the other part of the connector 13 installed in the second housing 210. The second housing 210 can be made of injection-molded engineering plastic parts.

[0086] This application further proposes that the circuit board 20 is mounted on the first housing 110, and a positioning post 315 is provided inside the second housing 210 in the direction facing the first housing 110. One end of the positioning post 315 is fixed to the inner wall of the second housing 210, and the other end of the positioning post 315 abuts against the circuit board 20.

[0087] The positioning post 315 refers to a columnar structure located on the inner wall of the second housing 210 and extending towards the first housing 110. It can be cylindrical or square, and its length is determined by the spacing between the housings 10. This structure provides physical restraint to the circuit board 20 through rigid contact, preventing displacement during assembly. The split housing 10 structure refers to the enclosed space formed by the first housing 110 and the second housing 210 through detachable connectors, which can be achieved using screws or clips. This design facilitates the step-by-step installation of the circuit board 20, allowing the positioning post 315 to automatically engage when the housing 10 is closed.

[0088] Specifically, during assembly, the circuit board 20 is pre-fixed inside the first housing 110. When the second housing 210 is closed with the first housing 110, the end of the positioning post 315 inside the second housing 210 directly abuts against the edge of the circuit board 20 or the preset positioning area. Since the positioning post 315 and the second housing 210 are an integrated structure or rigidly connected, they form a stable three-point or multi-point contact during the closing process, generating a uniform constraint force on the circuit board 20. This abutment relationship allows the circuit board 20 to maintain a stable position within the housing 10 without additional fixing devices, while avoiding displacement caused by vibration or external force. During the disassembly of the second housing 210, the positioning post 315 maintains axial positioning of the circuit board 20, preventing displacement of the circuit board 20 and loosening of internal circuits. During the reassembly of the second housing 210 with the first housing 110, the contact surface between the positioning post 315 and the circuit board 20 forms an anti-misalignment structure, ensuring the assembly accuracy after the housing 10 is closed.

[0089] In some specific embodiments, a buffer pad may be provided at the end of the positioning post 315 to reduce the impact of rigid contact on the circuit board 20. Furthermore, the distribution position of the positioning posts 315 on the inner wall of the second housing 210 can be adjusted according to the shape of the circuit board 20, for example, four positioning posts 315 may be symmetrically arranged at the four corners, or three linearly arranged positioning posts 315 may be arranged on the long side.

[0090] Compared to existing technologies, traditional power controllers often use screws to directly fix the circuit board 20 or use a snap-fit ​​structure for positioning. The former requires multiple alignments of the screw holes and is cumbersome, while the latter suffers from the problem of snap-fit ​​deformation leading to positioning failure. This solution achieves passive positioning of the circuit board 20 through an automatic abutment mechanism triggered by the positioning post 315 when the housing 10 is closed, eliminating the manual alignment step and avoiding the reliability risks associated with elastic snap-fit ​​structures. Through the above technical solution, this application achieves automatic positioning of the circuit board 20 during the assembly process of the housing 10, eliminating the step of manual position adjustment and significantly improving assembly efficiency; the physical limiting effect of the rigid positioning post 315 ensures that the circuit board 20 maintains a stable connection state even under vibration, avoiding poor contact or short circuit problems caused by displacement.

[0091] It should be noted that both the power supply wire and the decorative light wire can be connected to the power controller via the first quick connector, or only one side of the power supply wire or the decorative light wire can be connected to the power controller.

[0092] This application further proposes that the housing 10 is also provided with a wire hole 15, through which an external cable passes to the inside of the housing 10 and connects to the circuit board 20.

[0093] The wire hole 15 refers to a channel structure that penetrates the inner and outer walls of the housing 10. Specifically, it can be achieved by forming a circular through-hole on the side wall of the housing 10 using injection molding, providing a fixed path for the cable to pass through. The cable passing through the wire hole 15 means that the power cord or lighting connection wire extends into the housing 10 through the wire hole 15. Specifically, a rubber sealing ring can be nested inside the wire hole 15 to achieve a sealed fixation between the cable and the housing 10, preventing external dust or liquid intrusion. Specifically, the wire hole 15 is located on the side wall of the housing 10 and corresponds to the installation position of the circuit board 20. The cable extends directly from the outside of the housing 10 through the wire hole 15 to the connection end of the circuit board 20. After the power wire enters the housing 10 through the wire hole 15, its exposed wire end can be directly soldered to the circuit board 20 or plugged in via a terminal to complete the physical connection of the power input. During this process, the cable's path is restricted within the channel of the wire hole 15, avoiding redundant bending of the cable within the housing 10. Preferably, the anti-slip texture on the inner wall of the wire hole 15 increases the friction of the cable sheath, preventing the cable from shifting due to external pulling. Through the above technical solution, the fixed insertion of the cable within the wire hole 15 effectively limits its range of motion within the housing 10, preventing the cable from contacting internal components and causing a short circuit risk.

[0094] Furthermore, the circuit board 20 is equipped with a switch button, such as... Figure 5 and Figure 12As shown, the housing 10 is provided with a switch hole 16, and the switch button is displayed on the outside of the housing 10 through the switch hole 16.

[0095] Specifically, the switch button is activated by a spring to switch the circuit board 20. The switch button is displayed outside the housing 10 through the switch hole 16, which facilitates the control of the switch on the circuit board 20 and the switching of the decorative lights, making the operation simpler.
