Description

Technical Field

[0001] This utility model relates to the field of string light technology, and more specifically, to a string light assembly that is protected against short circuits. Background Technology

[0002] String lights typically refer to a series of decorative lights consisting of multiple small light bulbs connected in series or parallel, often used for holiday decorations, interior decorations, or outdoor lighting projects. A string light generally includes a positive wire and a negative wire, with the LEDs soldered between the positive and negative wires.

[0003] In existing technology, when soldering LED chips, the positive and negative wires are first placed on flat solder pads, and then the LED chip is soldered between the positive and negative wires. This can easily cause the solder between the positive and negative wires to flow together, resulting in a short circuit. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a string light assembly that is protected against short circuits.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0010] At least one LED bead is soldered at both ends to the positive and negative electrode wires, respectively.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects:

[0012] The bearing surface can support the positive and negative wires, and the insulating boss can separate the positive and negative wires. In this way, when soldering LED beads, the solder paste on the positive and negative wires will not flow together due to the blocking effect of the insulating boss, thus preventing short circuits.

[0013] Preferably, the positive electrode wire and the negative electrode wire are equal to or extend beyond the side of the insulating boss away from the substrate.

[0014] Preferably, the insulating boss is disposed at the center of the bearing surface.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] refer to Figure 1-3 A short-circuit-proof string light assembly includes: a substrate 1, an insulating boss 2, a positive electrode wire 3, a negative electrode wire 4, and at least one LED chip 5. The substrate 1 has a bearing surface 11. The insulating boss 2 is disposed on the bearing surface 11, and the bearing surface 11 is divided into two halves. The positive electrode wire 3 and the negative electrode wire 4 are respectively disposed on the two bearing surfaces 11 on both sides of the insulating boss 2. The two ends of the LED chip 5 are respectively soldered to the positive electrode wire 3 and the negative electrode wire 4.

[0025] Understandably, substrate 1 is the base component of this string light assembly. It can be a plate structure, a disc structure, a trapezoidal structure, etc., but is not limited to these. The bearing surface 11 is simply a plane; therefore, regardless of the shape of substrate 1, as long as a bearing surface 11 is provided on substrate 1, it is sufficient. The insulating boss 2 is a component used to separate the positive electrode wire 3 and the negative electrode wire 4. It can be integrally formed with substrate 1 or fixed by adhesive or snap-fit ​​methods. The insulating boss 2 serves as an insulating spacer; therefore, the insulating boss 2 can be made of insulating materials such as plastic or rubber, but is not limited to these. The positive electrode wire 3 and the negative electrode wire 4 can be made of bare copper wire, enameled wire split at the solder joint, or wire with insulation, etc., but are not limited to these. Multiple LED beads 5 can be spaced apart along the axial direction of the positive electrode wire 3 and the negative electrode wire 4.

[0026] With this setup, the positive wire 3 and the negative wire 4 are placed on the bearing surfaces 11 on both sides of the insulating boss 2 for support. The insulating boss 2 can separate the positive wire 3 and the negative wire 4. In this way, when soldering the LED beads 5, the solder paste on the positive wire 3 and the negative wire 4 will not flow together due to the blocking effect of the insulating boss 2, thus preventing short circuits.

[0027] In some embodiments, the positive electrode wire 3 and the negative electrode wire 4 are equal to or extend beyond the side of the insulating boss 2 away from the substrate 1. In this way, when soldering the lamp bead 5, it can be ensured that the lamp bead 5 is in contact with the positive electrode wire 3 and the negative electrode wire 4, and the lamp bead 5 will not be restricted due to the setting of the insulating boss 2.

[0028] In some embodiments, the insulating boss 2 is disposed in the center of the bearing surface 11. In this way, the two bearing surfaces 11 are uniformly symmetrical, and the positive electrode wire 3 and the negative electrode wire 4 disposed on the two bearing surfaces 11 are also symmetrically disposed, making the structure more regular and reasonable.

[0029] In some embodiments, a flexible partition 7 is provided on both bearing surfaces 11. It is understood that the flexible partition 7 acts as a support for the positive electrode wire 3 and the negative electrode wire 4, and can be made of materials such as rubber or sponge, but is not limited to these. Thus, the flexible partition 7 prevents rigid contact between the positive electrode wire 3 and the negative electrode and the substrate 1. Simultaneously, when welding the LED bead 5 or other components that press down on the positive electrode wire 3 and the negative electrode guide, the flexible partition 7 can also buffer them, providing protection.

[0030] In some embodiments, two grooves 71 are respectively provided on the two flexible partitions 7 for positioning the positive electrode wire 3 and the negative electrode wire 4, and the two grooves 71 are arranged in parallel. Here, the grooves 71 can be formed by indentation or by providing two spaced protrusions, etc., but are not limited to these. In this way, after the positive electrode wire 3 and the negative electrode wire 4 are positioned by embedding them into the two grooves 71 respectively, since the two grooves 71 are parallel, the distance between the two wires remains unchanged, which facilitates the soldering of the lamp bead 5.

[0031] In some embodiments, a base 6 is provided on the side of the substrate 1 facing away from the bearing surface 11. It is understood that the base 6 is a component for contacting the workbench surface or cooperating with other positioning fixtures, such as a plate structure, a locking structure, a column structure, etc., but not limited to these. Thus, the base 6 can support or position the entire string light assembly.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
