DETAILED DESCRIPTION OF THE EMBODIMENTS

The present disclosure will be explained below in conjunction with the accompanying drawings 1 to 9.

The present disclosure provides a fastening type waterproof LED lamp, including a housing 1, and further including a sealing plug 2, a waterproof plugging base 3, and a light-emitting assembly 4.

The fastening type waterproof LED lamp further includes a wiring seat 5 and a fixed seat 6; the fixed seat 6 is arranged in the wiring seat 5; a plugging slot 61 is provided in the fixed seat 6; a fastening position 62 is provided in the plugging slot 61; the waterproof plugging base 3 is plugged into the plugging slot 61, and the clamping tongue 31 is clamped into the fastening position 62; and hole positions 63 adapted to the conductive plugging columns are further provided in the plugging slot 61. The conductive plugging columns are plugged into the hole positions 63 to achieve electric connection of the lamp.

The present disclosure improves the connection mode for the lamp and the power cable. The mode for electrically connecting a metal threaded lamp holder to a metal copper sleeve of the traditional lamp is improved as fastening assembling between the lamp and the power cable. A metal pin is used inside to be electrically connected to the hole positions 63. This assembling mode saves a large number of metal raw materials and greatly reduces the manufacturing cost of the light string. The original metal material cost of about 0.6 yuan is reduce to about 0.06 yuan after the improvement, so that the cost is reduced by nearly ten times. Meanwhile, a lamp base with a large volume does not need to be coated and formed, so that the cost for plastic materials is also reduced. Secondly, in this technical solution, the sealing plug 2 improves the waterproof performance of a bulb, and the waterproof plugging base 3 is formed on the outer side of the opening part of the lampshade 1 again through injection molding, so that secondary waterproofing of the lamp is achieved. After the waterproof plugging base 3 is formed, the opening part of the housing 1 is thoroughly sealed, to achieve absolute sealing of the lamp. On the other hand, after the lamp and the wiring seat 5 are assembled in a fastened manner, so that the assembling is firm, convenient, and efficient. Furthermore, the lamp is removable and replaceable, so that the flexibility of the light string is higher.

In another embodiment, as shown in FIG. 2, the fastening type waterproof LED lamp further includes a first power-on wire 7; and the wiring seat 5 is electrically connected to the fixed seat 6 through the first power-on wire 7. This embodiment can present pendant decoration of the lamp. The decorative effect is better when the light string is hung outdoors.

When the plugging base does not include a second power-on wire 8, the first metal wire 41 and the second metal wire 43 directly extend out of a surface of the waterproof plugging base 3 through the wire guide holes 21 form the first conductive plugging column 32 with strength and the second conductive plugging column 33 with strength. At this time, each of the first conductive plugging column 32 and the second conductive plugging column 33 is a part of each metal wire.

In the above embodiment, as shown in FIG. 6, each of the first metal wire 41 and the second metal wire 43 is composed of two parts: a conductive wire 411 and a conductive column 412. A diameter of the conductive column 412 is greater than that of the conductive wire 411. At this time, the first conductive plugging column 32 and the second conductive plugging column 33 are arranged at the tail ends of the conductive column 412. This structure can ensure that the first metal wire 41 and the second metal wire 43 have sufficient strength to be plugged into the fixed seat 6, further save raw materials for the metal wires, and further reduce the manufacturing cost. As shown in FIG. 6, the first metal wire and the second metal wire are further provided with heat dissipation resistors 11.

As shown in FIG. 3, in yet another embodiment, the waterproof plugging base 3 further includes a second power-on wire 8; one end of the second power-on wire 8 is electrically connected to the waterproof plugging base 3; and the other end is electrically connected to the light-emitting assembly 4. This structure can achieve the pendant effect of the lamp too and improve the decorativeness of the lamp.

As a preference, a first positive wire 81 and a first negative wire 82 are arranged in the second power-on wire 8; the first positive wire 81 is connected to the first metal wire 41 through butt welding; and the first negative wire 82 is connected to the second metal wire 43 through butt welding; and the opening part of the housing 1 is sealed by injection molding. Similarly, the electric connection between the wiring seat 5 and the main power cable 9 is achieved by butt welding too. The butt welding here means that an electrode wire is directly heated to be welded with the other electrode wire after being dipped with tin, without wrapping by a copper terminal. Compared with a traditional method for achieving electric connection by wrapping a copper terminal around a light string or electrode wires of a lamp, electrically connecting the electrode wires in the butt welding manner can further ensure that the electrode wires are firmly electrically connected to the lamp either during secondary injection molding or during outdoor use at ordinary times, and poor contact of the lamp can be effectively prevented. In addition, the cost is lower.

In this technical solution, an isolation wall 34 is further arranged on a surface of the waterproof plugging base 3; and the fixed seat 6 is provided with an isolation slot 64 matched with the isolation wall 34. When the waterproof plugging base 3 is plugged into the fixed seat 6, the isolation wall 34 and the isolation slot 64 can be used to assist in precise positioning and mounting, to improve the assembling efficiency. In addition, the isolation wall 34 isolates a positive conductive plugging column from a negative conductive plugging column, to prevent a short circuit in the lamp due to accidental contact between electrodes. In this technical solution, the isolation wall 34 is asymmetrically arranged on the waterproof plugging base 3, namely, distances between the isolation wall 34 and two ends of the waterproof plugging base 3 are different, so that the isolation wall 34 can further prevent the electrodes of the lamp from being mistakenly plugged and improve the safety.

As shown in FIG. 1 and FIG. 3, the light-emitting lamp body 42 of this technical solution can be an LED light bar or an LED light bead. During production, a light-emitting element can be randomly selected according to a use requirement. The LED light bead can be a controllable seven-color light bead.

The present disclosure further includes a fastening type waterproof light string, including the above lamp, and further including a main power cable 9, a male plug 91, and a female socket 92. The male plug 91 and the female socket 92 are respectively arranged at two ends of the main power cable 9; and the wiring seat 5 is arranged in a middle part of the main power cable 9 and is electrically connected to the main power cable 9. The light string of the present disclosure is mainly used in outdoor parties and has all the advantages of low cost, high waterproof performance, simple structure, fast assembling, and the like of the above-mentioned lamp.

As a preference, the wiring seat 5 is provided with a hanging lug 51 convenient for hanging the light string outdoors.

To enlarge the range of application of the light string, the light string further includes a hook 10. An elastic clamping portion 101 is arranged at one end of the hook 10. During use, the elastic clamping portion 101 can be clamped into the hanging lug 51, to form a light string hanging structure as shown in FIG. 8. After the hanging lug 51 is used in conjunction with the hook 10, another form of hanging structure is achieved, so that the light string can be suitable for being used in more outdoor scenes has a wider range of application.

The above content only describes preferred embodiments of the present disclosure.
