Abstract

This invention discloses an outdoor lighting waterproof distribution system based on a waterproof base. The system uses a waterproof base (1) as its core structure, with a PCB distribution board (3) installed inside its cavity. Electrical connection points are completely sealed using a power mainline potting compound (9), forming an integrated waterproof distribution body. The PCB distribution board has an input connection part and multiple output connection parts; the power mainline (6) and parallel leads (7) are connected to the corresponding connection parts by welding or plugging. The parallel leads (7) are led out through a distribution lead-out shell (14) and waterproof insulating glue is injected through the parallel lead glue injection hole (12). After curing, a parallel lead potting compound (13) is formed, achieving a waterproof seal at the outlet. This invention provides a highly reliable basic power supply connection platform for outdoor lighting through modularization and dual potting processes.

Description

Technical Field

[0002] This invention relates to the field of outdoor electrical lighting and power supply technology, specifically to a modular, glue-filled, waterproof wiring system for outdoor lighting projects, built on a waterproof base. Background Technology

[0004] This application is a technical extension of the original application (application number: CN202310358071.8, title: A Waterproof Outdoor Bulb), and proposes a completely new, system-level inventive subject on this basis. The original application provides a waterproof outdoor bulb, the core of which is to solve the internal waterproofing problem of a single lamp through a structure of "waterproof base + potting compound".

[0005] The inventors recognized that the value of this core waterproof structure extends far beyond protecting individual light fixtures. A fundamental pain point in the outdoor lighting industry lies in the power supply connection points between multiple light fixtures, which are the weakest and most unreliable link in traditional waterproofing methods. Therefore, how to innovatively expand and reconstruct the proven and highly effective waterproofing technology concept from protecting "a single point (light fixture)" into a system-level solution protecting "a single line (power supply link)" has become a novel technical problem unsolved by existing technologies. This application is proposed against this backdrop. Summary of the Invention

[0007] (a) Purpose of the invention

[0008] This invention aims to overcome the shortcomings of existing technologies and provide a modular, glue-filled, waterproof branching system based on a waterproof base to completely solve the three core pain points of poor waterproof reliability, low construction efficiency, and inconvenient maintenance in outdoor lighting.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] An outdoor lighting waterproof distribution system based on a waterproof base is characterized by comprising: a waterproof base (1), a PCB distribution board (3), a power main line potting compound (9), a branch line lead-out shell (14), a parallel lead line potting compound (13), and a waterproof connector (8). The waterproof base (1) has an internal cavity and is provided with a main line inlet (10), multiple branch line outlets (11), and a waterproof base injection hole (2). The PCB distribution board (3) is fixedly installed in the cavity of the waterproof base (1) and is provided with an input connection part and multiple output connection parts; the input connection part and each output connection part are electrically connected through copper-clad lines on the PCB to complete the "one-to-many" power distribution; the connection between the wires and the connection parts is achieved by welding or plugging. The power main line potting compound (9) is formed by waterproof insulating glue injected from the waterproof base injection hole (2) and cured, and completely covers the PCB distribution board (3) and its electrical connection points. The branch lead-out shell (14) is located at the branch lead-out port (11), and is filled with parallel lead-in potting compound (13) injected and cured from the parallel lead-in injection hole (12) to achieve waterproof sealing of the parallel lead-out port (7). The waterproof connector (8) is connected to the end of each parallel lead-in (7) leading out from the branch lead-out shell (14); the waterproof connector (8) is a mating connector that can achieve blind mating and achieve an IP65 or higher protection level.

[0012] (III) Beneficial Effects

[0013] Compared with existing technologies, the significant advantages of this invention are: 1. Revolutionary waterproof reliability, achieving permanent IP68 protection through a double potting and sealing process; 2. Extremely high construction efficiency and consistency, prefabricating complex work in the factory and achieving "plug and play" on site; 3. Significantly convenient maintenance, enabling quick replacement through waterproof connectors without damaging the waterproof structure; 4. Safer and more stable electrical connections.

Detailed Implementation

[0021] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] During construction, the "waterproof distribution line" is first prefabricated in the factory:

[0023] The main power line (6) is passed through the main line inlet (10) of the waterproof base (1) and connected to the input terminal (4) of the PCB distribution board (3) by soldering.

[0024] One end of each of the multiple parallel leads (7) is connected to the output terminal (5) of the PCB branch board (3) by soldering. The soldering method is either immersion soldering or manual soldering. The parallel leads (7) are inserted into the branch lead-out shell (14), and the other end is fitted with a waterproof connector (8).

[0025] The PCB branch board (3) is securely fixed in the cavity of the waterproof base (1), and then high-performance epoxy resin waterproof insulating glue is injected through the glue injection hole (2) of the waterproof base until the glue fills the cavity. After curing, it forms a power main line potting glue (9).

[0026] Subsequently, polyurethane waterproof insulating adhesive is injected through the parallel lead injection hole (12) on the branch lead housing (14), and after curing, it forms a parallel lead potting compound (13).

[0027] Ultimately, a robust, ready-to-use "waterproof splitter" module was obtained.

[0028] At the outdoor site, connect the main power supply to the input end of the branch line, and then connect each lighting light source to the waterproof connector (8) brought out on the branch line to complete the installation.

[0029] The input connection and output connection can be terminals, pads or solder holes on the PCB board, preferably output terminals (5) and input terminals (4); the connection between the wire and the connection can be achieved by direct soldering or by inserting and soldering the terminal block to the connection.
