The waterproof rubber plug (2400) comprises a first annular bottom surface (2410), a second annular bottom surface (2420) and a slanting helical annular surface (2430), the inner diameters of which are all d3, the outer diameters of which are all d4, and the width of the slanting helical annular surface (2430) is w1; the inner diameter of the A end of the connecting body (2300) is d1, and the inner diameter of the B end is d2; the first waterproof nut (2500) matches the second thread (2320), the inner diameter of the cavity is d5, and the inner diameter of the inlet is d6; in particular, the inner and outer diameters meet d1>d2>d3, d3 is equal to d6, d4 is equal to d5, and w1 is equal to d4 / 2; the first annular bottom surface (2410) is adjacent to the B end of the connecting body (2300);

[0033] The slanting helical annular surface (2430) has three slanting helical annular surfaces, which are uniformly arranged, and the angle between adjacent two slanting helical annular surfaces is 120°; each slanting helical annular surface rotates 2 turns counterclockwise along the axial direction (direct1) from the second annular bottom surface (2420) to the first annular bottom surface (2410); the axial direction is the direction from the center of the second annular bottom surface (2420) to the center of the first annular bottom surface (2410); the angle α between the intersection line of the slanting helical annular surface (2430) and the cross section passing through the axis and the axial direction is 30°; the intersection line of the slanting helical annular surface (2430) and the first annular bottom surface (2410) is a first Archimedean spiral (L1), and the intersection line of the slanting helical annular surface (2430) and the second annular bottom surface (2420) is a second Archimedean spiral (L2); the intersection lines on the two surfaces are the same size and mirror symmetric in shape.

[0035] The waterproof rubber plug of the waterproof joint can be tightly wound around the wire passing through the middle of each inclined spiral ring surface through the spinning of the first waterproof nut in the fastening process, and the number of turns of each inclined spiral ring surface can produce the same number of sealing effects on the wire passing through the middle; the combination of multiple inclined spiral ring surfaces produces multiple times the sealing effect of each inclined spiral ring surface, greatly enhancing the reliability and safety of the waterproof joint; at the same time, compared with the existing waterproof joint which usually adopts a single rubber ring combined with a spinning of a forced head to make the rubber ring shrink and then fasten around the wire for waterproof, the waterproof rubber plug combined with the first waterproof nut in the embodiment can produce multiple composite waterproof effects, and the waterproof effect is stronger; in addition, for the existing type of waterproof joint, the line diameter range covered by a single waterproof joint is small, resulting in the need for multiple different models to cover a variety of line diameters of different thicknesses, while the waterproof joint adopted in the embodiment can cover a larger line diameter range, and the same line diameter range can be covered with fewer models, effectively improving the application range of a single waterproof joint.

[0036] Further, the waterproof joint (2000) can be installed on a round hole opened on a junction box as shown in Figures 1-8 、 Figure 18 ;

[0037] The junction box body (1000) comprises a waterproof shell (1100), a terminal block (1200), an inner cover plate (1300), a toggle switch (1400) and an internal circuit; the waterproof shell (1100) comprises a first screw (1110), a waterproof upper cover (1120) and a waterproof base (1130); the waterproof upper cover (1120) comprises a first circular hole (1121) and a waterproof rubber strip (1122); the waterproof base (1130) comprises a first screw hole (1131), a second circular hole (1132), a third circular hole (1133) and a strip-shaped protrusion (1134); in particular, the waterproof upper cover (1120) and the waterproof base (1130) are made of gray ABS plastic; the waterproof rubber strip (1122) is embedded in the waterproof upper cover (1120), and the profile of the waterproof rubber strip (1122) matches the strip-shaped protrusion (1134); when the waterproof upper cover (1120) is placed on the waterproof base (1130), it plays a sealing role; the first screw (1110) matches the first screw hole (1131), and the first screw (1110) can pass through the first circular hole (1121) to tightly fasten the waterproof upper cover (1120) on the waterproof base (1130); the second circular hole (1132) is adapted to the waterproof connector (2000), and the waterproof connector (2000) can be tightly connected and fixed on the junction box body (1000); the number is six; the third circular hole (1133) is used to fix the junction box body (1000) in the interior of the street lamp.

[0038] The terminal block (1200) comprises an indication triangle (1210), a second screw (1220) and a terminal inlet (1230); the indication triangle (1210) is used to identify the input and output of the electrical signal; in particular, the No. 1 to No. 3 terminal inlets are used for power input, the No. 4 to No. 8 terminal inlets are used for single lamp controller input and output, the No. 9 to No. 15 terminal inlets are used for LED power input and output, and the No. 16 to No. 17 terminal inlets are used for LED light emitting module input and output; each continuous terminal inlet is only used for the input and output of a single device, thereby avoiding the problems of line sequence confusion and unclear wiring logic from the source; the second screw (1220) is used to fasten the wire head coming from the waterproof connector (2000) in the terminal inlet (1230); the indication triangle (1210), the second screw (1220) and the terminal inlet (1230) are all 17; in particular, the terminal can adopt the common terminal type on the market, which is safe, stable and low in cost.

[0039] The inner cover plate (1300) comprises a first square hole (1310), a third screw (1320) and an indication number (1330); in particular, the material of the inner cover plate (1300) is gray ABS plastic; the size of the first square hole (1310) is matched with the toggle switch (1400), and the toggle switch (1400) can normally switch between the open and closed states; in particular, the voltage borne by the toggle switch (1400) is 220V, and the maximum current borne is not less than 5A; the toggle switch (1400) meets the open state when the single lamp controller (S01) is connected, and meets the closed state when the single lamp controller (S01) is not connected, and is electrically connected with the wiring terminal block (1200) in the internal circuit; the indication number (1330) is from 1 to 17;

[0040] The existing intelligent street lamp mainly comprises three main components of an LED power supply, an LED light emitting module and an LED single lamp controller. Due to various types of new and old street lamps, manufacturing periods and installation methods are not the same, so that there is no unified wiring method when the three main components are connected. Usually, the wire ends matched between different components are connected by using an insulating tape or a wiring terminal. This method has the following inherent disadvantages: 1. The wire sequence is chaotic, the internal wiring of the LED street lamp is chaotic and irregular, and when the street lamp fails, it is not conducive to troubleshooting; 2. The wiring logic is not clear. Since there is no unified connection method, the wire ends are matched complicatedly and are easily connected incorrectly when the LED power supply, the LED light emitting module and the LED single lamp controller are connected by wire ends, which brings difficulties to the assembly of the street lamp; 3. Since the LED street lamp generates heat when emitting light, the LED street lamp rear shell is generally provided with upward heat dissipation holes. When the insulating tape or the wiring terminal is used for wiring, due to the problem of insufficient waterproof performance, the street lamp is easily invaded by rainwater, causing short circuit, aging, poor contact and other durability problems, affecting the normal work and service life of the street lamp. Therefore, a new device needs to be designed to solve the problems of chaotic wire sequence, lack of unified connection method and durability caused by using the insulating tape or the wiring terminal for wiring. The waterproof joint for the intelligent street lamp wiring provided by the embodiment of the present application can provide a unified and regular wiring method for the LED power supply, the LED light emitting module and the LED single lamp controller in the intelligent street lamp, so as to overcome the disadvantages of chaotic wire sequence, unclear wiring logic and non-waterproof joint of the existing wiring method, and solve the durability problem caused by using the insulating tape or the wiring terminal for wiring. The device is also applicable to the case that there is no single lamp controller in the street lamp, expands the application range and enhances the popularization.

[0041] The various embodiments in the specification are described in a progressive manner, and the same and similar parts between the various embodiments can be referred to each other, and each embodiment focuses on the difference from other embodiments. The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
