Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a waterproof underground lamp. Background Art

[0002] Underground lights are lamps buried in the ground and are widely used in outdoor places such as squares, parks and tourist attractions to beautify and illuminate. Underground lights for fire fighting can also be used as indicator devices to indicate safe passages.

[0003] When the underground lamp is installed on the ground, external wires for power supply or signal transmission are pre-installed on the ground. The circuit board inside the underground lamp is connected to the external wires through the internal wires. The connection between the internal wires and the external wires is tightened by a transition structure or by tape to achieve waterproofing. However, the waterproofing effect is poor. Moreover, since the underground lamp is arranged on the ground, accumulated water can easily come into contact with the external wires, causing water to easily enter the interior of the underground lamp through the guidance of the external wires and the internal wires and come into contact with the circuit board, causing damage to the circuit board. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings and deficiencies in the prior art and to provide a waterproof underground lamp.

[0035] See also Figures 1 to 4 One embodiment of the present invention provides a waterproof underground lamp, comprising:

[0036] The housing 10 has an accommodating cavity 11 and a junction box 12 disposed therein. The accommodating cavity 11 is connected to the junction box 12 via a plurality of through holes 13. In this embodiment, the housing 10 includes a top cover 14, a middle shell 15, and a bottom shell 16 connected in sequence. The accommodating cavity 11 is formed between the top cover 14 and the middle shell 15, and the junction box 12 is disposed between the middle shell 15 and the bottom shell 16. Of course, in other embodiments, the housing 10 may also adopt other suitable designs.

[0037] The light source assembly 20 is disposed in the accommodating cavity 11 .

[0038] The circuit board 30 is disposed in the accommodating cavity 11 and is electrically connected to the light source assembly 20 .

[0039] The terminal assembly 40 is disposed in the junction box 12 and is electrically connected to the circuit board 30 via a conductive member 41 . The conductive member is passed through the through hole 13 .

[0040] The colloid structure (not shown) is disposed at the through hole 13 to seal the through hole 13 .

[0041] The external wires are electrically connected to the terminal assembly 40, and the external wires (not shown) are electrically connected to the circuit board 30 through the terminal assembly 40, while the accommodating cavity 11 and the junction box 12 are separated from each other. The through hole 13 connecting the accommodating cavity 11 and the junction box 12 is completely sealed by the colloid structure, which can achieve a better waterproof effect and prevent moisture from entering the accommodating cavity 11.

[0042] In addition, the waterproof underground lamp itself has no exposed wires outside the accommodating cavity 11 and the junction box 12, which can prevent water from entering the junction box 12 or the accommodating cavity 11 along the wires and is conducive to waterproofing.

[0043] See also Figures 4 to 6 In some optional embodiments, a wiring hole 121 connected to the outside of the wiring box 12 is provided in the wiring hole 121, and external wires enter the wiring box 12 through the wiring hole 121. The colloid structure seals the wiring hole 121, thereby preventing moisture from entering the wiring box 12 along the external wires.

[0044] In some optional embodiments, the wiring hole 121 and the through hole 13 are connected to each other, thereby simplifying the structure of the housing 10 and simplifying the production process.

[0045] In some optional embodiments, the junction box 12 is provided with a colloid filling port 122, and the colloid structure fills the interior of the junction box 12 and the colloid filling port 122. The colloid structure seals the interior of the junction box 12 as a whole, thereby achieving waterproofing of the terminal assembly 40 and preventing moisture from entering the interior of the junction box 12. The colloid structure can be filled into the junction box 12 from the colloid filling port 122 after the external wires are connected to the terminal assembly 40, thereby facilitating the installation of the external wires. When the colloid structure is filled, the colloid structure can flow to the through-hole 13 and the wiring hole 121, thereby achieving the filling of the colloid structure at the through-hole 13 and the wiring hole 121. In addition, it should be noted that the colloid structure at the through-hole 13 can be filled in advance before the external wires are connected to the terminal assembly 40, or it can be filled after the external wires are connected to the terminal assembly 40.

[0046] In some optional embodiments, the junction box 12 is provided with a first box cavity 123 and a second box cavity 124 that are interconnected, the colloid filling port 122 is connected to the first box cavity 123, the terminal assembly 40 and the wiring hole 121 are arranged in the second box cavity 124, the accommodating cavity 11 is connected to the second box cavity 124 through the through hole 13, the colloid structure fills the second box cavity 124, and the first box cavity 123 may not be filled with the colloid structure, thereby saving costs.

[0047] The colloid structure can adopt appropriate colloid types to achieve better waterproof effect.

[0048] In some optional embodiments, the junction box 12 is provided with an opening 125 and a cover 126 that movably closes the opening 125. The cover 126 can open the opening 125 to facilitate the connection between the external wires and the terminal assembly 40. After the cover 126 closes the opening 125, a gel structure can be filled into the junction box 12 to seal the opening 125 and prevent moisture from entering the junction box 12 through the gap between the opening 125 and the cover 126. Of course, the gel structure can also be free from contact with the cover 126. The gel structure only needs to cover the wiring hole 121, the external wires, the terminal assembly 40, and the through hole 13, so that the cover 126 can still be opened after the gel structure is filled.

[0049] In some optional embodiments, the box cover 126 is rotatably matched with the junction box 12 to facilitate the movement of the box cover 126. Of course, the box cover 126 can also be slidably matched with the junction box 12 to achieve movement.

[0050] In some optional embodiments, a buckle 127 is provided on the junction box 12 . When the box cover 126 closes the opening 125 , the buckle 127 is engaged with the box cover 126 , thereby facilitating the fixing of the box cover 126 .

[0051] The specific structure of the accommodating chamber 11 can be appropriately designed according to actual needs. For example, in some optional embodiments, the accommodating chamber 11 includes a first chamber 111 and a second chamber 112 that are interconnected, the circuit board 30 is arranged in the first chamber 111, and the light source assembly 20 is arranged in the second chamber 112; the first chamber 111 is connected to the junction box 12 through the through hole 13.
