Description

Technical Field

[0001] The utility model relates to the technical field of wire connection, and more specifically to a connector for a Christmas light string. Background Art

[0002] Mood light strings, also often called LED light strings, decorative light strings or holiday light strings, are decorative lighting products used to create a warm, romantic or festive atmosphere. They usually consist of a series of small bulbs (now mostly energy-saving and durable LED lamp beads), which are connected in series or parallel by thin wires, and some are equipped with controllers to achieve different lighting modes, such as flashing, gradient, fixed color or color cycle effects.

[0003] Ambient light string lights are made up of multiple lamps connected by wires. When the wires are broken, they need to be reconnected. In the prior art, the wires are usually connected and wrapped with electrical tape, or connected with connectors. String lights are usually hung outdoors. Wrapping with electrical tape is not waterproof. With the connectors in the prior art, water can easily enter the connector from both ends of the connector, that is, the holes where the wires pass through the connector. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a connector for a Christmas light string which is easy to assemble and disassemble and has a waterproof effect.

[0005] To solve the above problems, the utility model adopts the following technical solutions: A connector for a Christmas light string, including a wire, and further comprising:

[0006] The connector body is used to connect the electric wires. Two conical openings are provided at both ends of the connector for the power wires to pass through, and the ends with smaller diameters of the two openings are arranged opposite to each other.

[0007] The cap is detachably mounted on both ends of the connector body, and a sleeve hole for sleeves on the wires is opened in the middle;

[0008] A sealing plug is installed at one end of the cover cap close to the opening and is slidably sleeved on the wire;

[0009] When the cover cap is installed on the connector body, the sealing plug is squeezed and deformed by the inner wall of the opening to seal the opening.

[0010] Preferably, the cap is threadably connected to the connector body.

[0011] Preferably, the sealing plug is conical, and the end with a smaller diameter faces the opening.

[0012] Preferably, the diameter of the small-diameter end of the sealing plug is larger than the diameter of the small-diameter end of the opening.

[0013] Preferably, a push ring is installed at one end of the cover cap close to the opening, and the sealing plug is installed on the push ring.

[0014] Preferably, the connector body comprises an upper cover and a lower cover, and cavities are provided on opposite sides of the lower cover. A receiving groove for overlapping wires is installed on the cavity of the lower cover, and a presser arranged opposite to the receiving groove is installed in the cavity of the upper cover. After the upper cover and the lower cover are closed, the presser presses the wires into the receiving groove.

[0015] Preferably, the upper cover and the lower cover are fixed by using locking members.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] After the two wires on the two atmosphere lights are connected through the connector body, the two caps are installed at both ends of the connector body, thereby driving the sealing plug to be inserted into the opening. The sealing plug is squeezed and deformed by the inner wall of the opening and compressed, thereby sealing the opening. The sealing plug and the wires are also sealed to prevent water from entering the interior through the openings at both ends of the connector body. The structure is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] refer to Figure 1-2, a connector for a Christmas light string, including an electric wire 1, which also includes: a connector body 2, used to connect the electric wire 1, two conical openings 23 for the power supply line 1 to be inserted are provided at both ends of the connector, and the ends with smaller diameters of the two openings 23 are arranged opposite to each other; a cap 3, which is detachably mounted at both ends of the connector body 2, and a sleeve hole 31 is provided in the middle part to be sleeved on the electric wire 1; a sealing plug 4, which is mounted on the end of the cap 3 close to the opening 23, and is slidably sleeved on the electric wire 1; when the cap 3 is installed on the connector body 2, the sealing plug 4 is squeezed and deformed by the inner wall of the opening 23 to seal the opening 23. It can be understood that the sealing plug 4 is squeezed and deformed, and has a sealing effect, which requires the use of deformable elastic materials, such as rubber, silicone, etc. The removable installation of the cap 3 can be connected to the connector body by a threaded connection, or it can be connected by a snap-on structure, etc. With such a configuration, refer to Figure 2-3 During installation, the two caps 3 are respectively put on the two wires 1 of the atmosphere lamp, and then the two wires 1 are connected through the connector body 2, and then the two caps 3 are installed at both ends of the connector body 2. At this time, the cap 3 drives the sealing plug 4 to be inserted into the opening 23, and the sealing plug 4 is deformed and squeezed by the inner wall of the opening 23 to seal the opening 23, thereby playing a waterproof role.

[0025] refer to Figure 2-3 In some embodiments, the sealing plug 4 is tapered, and the end with a smaller diameter faces the opening 23. It can be understood that since the opening 23 is also tapered, and the ends with a smaller diameter of the opening 23 are arranged opposite to each other, here, the sealing plug 4 and the opening 23 are both tapered, and one end must have a larger inlet and one end has a smaller diameter. The sealing plug 4 of the same shape is more tightly sealed after being embedded in the opening 23. Further, in order to ensure that the sealing plug 4 can seal the opening 23, the diameter of the small-diameter end of the sealing plug 4 is larger than the diameter of the small-diameter end of the opening 23 to prevent the sealing plug 4 from completely passing through the opening 23.

[0026] In some embodiments, a push ring 5 is installed at one end of the cap 3 close to the opening 23, and the sealing plug 4 is installed on the push ring 5. It can be understood that the push ring 5 is a ring-shaped structure sleeved on the wire 1, and its function is to extend the depth of the sealing plug 4 pushed into the opening 23, so that the sealing of the opening 23 is tighter.

[0027] In some embodiments, the connector body 2 includes an upper cover 21 and a lower cover 22, and the lower cover 22 and the lower cover 22 have cavities on their opposite sides. A receiving groove 221 for overlapping the wires 1 is installed on the cavity of the lower cover 22, and a down-presser 211 arranged opposite to the receiving groove 221 is installed in the cavity of the upper cover 21. After the upper cover 21 and the lower cover 22 are closed, the down-presser 211 presses the wires 1 into the receiving groove 221. During installation, the insulation layer of the two wires 1 ports is removed to expose the copper wires, and the exposed parts of the two copper wires are entangled and embedded in the receiving groove 221. Then, the upper cover 21 and the lower cover 22 are closed, so that the down-presser 211 presses the exposed parts of the two wires 1 into the receiving groove 221, and finally, the upper cover 21 and the lower cover 22 are locked and fixed by a locking member. The locking member can be bolted, riveted, keyed, etc.

[0028] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
