[0024] To help those skilled in the art better understand the present invention, the present invention is further described in detail below with reference to the accompanying drawings. The embodiments described herein are merely a portion of the present invention, not all of the present invention. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0025] refer to Figure 1 As shown, a waterproof lamp can be used for lighting in water environments such as bathtubs and swimming pools. The waterproof lamp includes a lamp body 1, a wire inlet socket 2 disposed at the bottom of the lamp body 1, and a circuit line 3. In this embodiment, the wire inlet socket 2 and the lamp body 1 are integrally formed.

[0026] Specifically, refer to Figure 2 and Figure 4 As shown, the lamp body 1 is provided with a PCB circuit board 4 and a lamp board 5 electrically connected to the PCB circuit board 4. Several LED lamp beads 52 are arranged on the lamp board 5. In this embodiment, the arrangement of the LED lamp beads 52 includes, but is not limited to, a circular arrangement or a linear arrangement. A male terminal 6 is provided on the PCB circuit board 4, and a female terminal 7 is provided at one end of the circuit line 3. The female terminal 7 selectively extends into the lamp body 1 through the wire inlet socket 2 and connects to the male terminal 6. The circuit line 3 is connected to the male terminal 6 on the PCB circuit board 4 via the female terminal 7 at its end, forming a complete circuit loop. When the male terminal 6 and the female terminal 7 are connected, electrical energy is transmitted from the power source through the circuit line 3, the female terminal 7, and the male terminal 6 to the PCB circuit board 4. The PCB circuit board 4 receives the electrical energy from the power source and, based on the preset circuit logic, transmits a control signal to the lamp board 5 through the circuit connection, driving the LED lamp beads 52 to emit light, thus achieving the lighting function. At the same time, by embedding the male terminal 6 into the lamp body 1, and selectively extending the female terminal 7 connected to the circuit line 3 into the lamp body 1 through the wire inlet seat 2 to connect with the male terminal 6, there is no need to waterproof the plug-in position of the female terminal 7 and the male terminal 6, thereby reducing the demand for sealing parts, simplifying the structure of the lamp, and reducing the production cost of the lamp.

[0027] A first waterproof sealing ring 8 is provided between the inlet seat 2 and the circuit line 3. A lock nut 9 is provided on the outer sleeve of the circuit line 3. The lock nut 9 is selectively fixedly connected to the inlet seat 2 to lock the first waterproof sealing ring 8 in the inlet seat 2. Specifically, the outer surface of the inlet seat 2 is provided with an external thread 21, and the inner surface of the lock nut 9 is provided with an internal thread (not shown in the figure) that matches the external thread 21. The inner surface of the lock nut 9 is threadedly connected to the outer surface of the inlet seat 2 to lock the first waterproof sealing ring 8 in the inlet seat 2.

[0028] By arranging a first waterproof sealing ring 8 between the incoming wire seat 2 and the circuit line 3, and fixing the first waterproof sealing ring 8 to the incoming wire seat 2 through the lock nut 9 to firmly lock the first waterproof sealing ring 8 in the incoming wire seat 2, it is possible to prevent water, moisture or other liquids from entering the interior of the lamp body 1 from the incoming wire seat 2, thereby achieving waterproof sealing treatment of the PCB circuit board 4, lamp board 5, male terminal 6 and female terminal 7, and avoiding contact between the first waterproof sealing ring 8 and external liquids, moisture, etc., thereby enhancing the waterproof sealing effect of the lamp.

[0029] A accommodating cavity 22 is provided in the wire inlet seat 2, and a wire inlet port 23 is provided on the end surface of the accommodating cavity 22 close to the lamp body 1. The accommodating cavity 22 is connected with the interior of the lamp body 1 through the wire inlet port 23, and the outer diameter of the female terminal 7 is less than or equal to the diameter of the wire inlet port 23. The female terminal 7 selectively extends into the lamp body 1 through the wire inlet port 23 and is connected to the male terminal 6 to form a complete circuit loop.

[0030] The accommodating cavity 22 includes a first cavity 221 and a second cavity 222, which are arranged in sequence along a direction away from the lamp body 1. The first cavity 221 and the second cavity 222 are coaxially arranged and connected. The cross-sectional area of ​​the first cavity 221 is smaller than the cross-sectional area of ​​the second cavity 222. The wire inlet 23 is provided on the end surface of the first cavity 221 close to the lamp body 1. The female terminal 7 is selectively installed in the first cavity 221; the first waterproof sealing ring 8 is selectively installed in the second cavity 222. The second cavity 222 is a hollow funnel-shaped cavity, wherein the second cavity 222 includes a first end close to the first cavity 221 and a second end away from the first cavity 221. The diameter of the first end is smaller than that of the second end. The first waterproof sealing ring 8 is a truncated cone-shaped sealing ring that matches the funnel-shaped cavity. When in use, the outer surface of the truncated cone-shaped sealing ring can closely fit the inner surface of the funnel-shaped cavity, thereby enhancing the waterproof sealing effect.

[0031] Preferably, at least one limiting groove 721 is provided on the outer side of the end body 72 along the axial direction, and a limiting protrusion 223 matching the limiting groove 721 is provided on the inner wall of the accommodating cavity 22. The limiting groove 721 is selectively connected to the limiting protrusion 223 in an axial sliding manner. The sliding connection design of the limiting groove 721 and the limiting protrusion 223 can not only achieve accurate positioning of the end body 72 during the connection process, making the operation of the end body 72 more convenient, but also enable the end body 72 and the accommodating cavity 22 to be stably slidably connected. In this embodiment, a limiting groove 721 is provided on the outer side of the end body 72 along the axial direction, and the limiting protrusion 223 is provided on the inner side wall of the first cavity 221.

[0032] The female terminal 7 includes a detachably connected end cap 71 and an end body 72. The outer diameter of the end cap 71 is smaller than the diameter of the wire inlet 23, and the outer diameter of the end body 72 is larger than the diameter of the wire inlet 23. The end body 72 selectively contacts the inner side of the end face of the accommodating cavity 22 on the side close to the lamp body 1. The first waterproof sealing ring 8 is sleeved on the circuit line 3 and contacts the end body 72. The connection method between the end cap 71 and the end body 72 includes but is not limited to any one of a threaded connection and a snap-on connection. In this embodiment, the end cap 71 is connected to the end body 72 by a thread.

[0033] Preferably, the outer diameter of the first waterproof sealing ring 8 is greater than or equal to the outer diameter of the end body 72, and the inner diameter of the first waterproof sealing ring 8 is smaller than the outer diameter of the end head 71. Since the outer diameter of the end head 71 is smaller than the diameter of the wire inlet 23, and the outer diameter of the end body 72 is larger than the diameter of the wire inlet 23, when the female terminal 7 is inserted into the wire inlet 23, its end head 71 is inserted into the wire inlet 23 until it is connected with the male terminal 6, and one end of the end body 72 gradually approaches the end surface of the accommodating cavity 22 on the side close to the lamp body 1 until it is in close contact with the inner side of the end surface, thereby cooperating with the first waterproof sealing ring 8 to achieve a better waterproof sealing effect on the wire inlet 23.

[0034] Preferably, a waterproof gasket (not shown) is further provided on the inlet socket 2, and both ends of the waterproof gasket can be in close contact with the lamp body 1 or the lock nut 9. The waterproof gasket is used to prevent external liquids, water vapor, etc. from entering through the contact surface between the lock nut 9 and the inlet socket 2, further enhancing the sealing effect of the lamp.

[0035] In this embodiment, the assembly process of the waterproof lamp is as follows: the circuit line 3 is extended into the lamp body 1 from the line inlet 23 of the line inlet seat 2, so that the limiting groove 721 on the outer side of the end body 72 of the female terminal 7 is connected with the limiting protrusion 223 of the accommodating cavity 22 along the axial sliding, and then the end of the end body 72 connecting the end head 71 is in close contact with the end surface of the first cavity 221. At this time, the connection between the end head 71 of the female terminal 7 and the male terminal 6 is completed; then the first waterproof sealing ring 8 is set on the circuit line 3, and slide along the direction of the female terminal 7, so that the first waterproof sealing ring 8 enters the second cavity 222, and is in close contact with the end body 72 to form a tight waterproof barrier; finally, the waterproof gasket is sleeved on the outside of the incoming wire seat 2, and the lock nut 9 is connected to the nut on the outer surface of the incoming wire seat 2 to lock the first waterproof sealing ring 8 in the second cavity 222; at the same time, the two ends of the waterproof gasket are in close contact with the lamp body 1 and the lock nut 9 respectively; thereby completing the assembly of the waterproof lamp.

[0036] refer to Figure 4 and Figure 6 As shown, the lamp body 1 includes a lamp holder 11 and a lampshade 12 mounted on the lamp holder 11, and the PCB circuit board 4 and the lamp board 5 are located in the lamp holder 11. In this embodiment, the lampshade 12 is made of light-transmitting material or transparent material.

[0037] refer to Figure 2 、 Figure 3 As shown, a first groove 13 is circumferentially provided on the contact surface between the lamp holder 11 and the lampshade 12, and a second groove 14 is provided on the contact surface inside the first groove 13. The second groove 14 is arranged along the circumferential inner side of the first groove 13. A protrusion 15 is provided on the lampshade 12 near the lamp holder 11, matching the first groove 13. The protrusion 15 is fixedly engaged with the first groove 13, and a second waterproof sealing ring 10 is provided in the second groove 14. The second waterproof sealing ring 10 is an annular sealing ring with a circular cross-section.

[0038] By arranging a second waterproof sealing ring 10 in the second groove 14, it is possible to prevent water, moisture or other liquids from entering the interior of the lamp body 1 through the gap between the lamp holder 11 and the lampshade 12, further improving the sealing of the lamp and making the lamp have a higher waterproof effect.

[0039] In this embodiment, the contact surface between the lamp holder 11 and the lampshade 12 is an ultrasonic welding surface. After the protrusion 15 of the lampshade 12 is fixedly engaged with the first groove 13 of the lamp holder 11, ultrasonic welding is performed. The high-frequency oscillation energy of the ultrasonic wave locally heats the protrusion 15 and the first groove 13 and cleans the surface. Then, pressure is applied to weld the lamp holder 11 and the lampshade 12.

[0040] The PCB circuit board 4 is provided with a plurality of positioning holes (not shown in the figure), and the light board 5 is correspondingly provided with a plurality of positioning posts 51. The positioning holes and the positioning posts 51 are detachably connected by a positioning screw 41, thereby realizing the detachable connection between the light board 5 and the PCB circuit board 4.

[0041] The waterproof lamp provided in this embodiment can achieve overall waterproofing of the lamp by only making a waterproof design inside the wire inlet seat 2. It has a simple structure, is easy to install, has a low manufacturing cost, and has good waterproof performance.
