Description

LED light string

The present invention provides an LED light string, especially one that can perform rapid assembly and mass production of automated LED light strings through three process steps with only four components.

The conventional light string comprises five main components: an LED light-emitting element (light bulb), a soft head, a soft core, a terminal and an electric wire. The LED light-emitting element may further comprise a lamp cover, thereby constituting six parts. The light string is combined, and the wires of the above-mentioned conventional light string are in the form of two parallel rows in the same direction. The process and assembly process of the conventional light string need to include at least the following: 1. The terminal is first cut and machined by machining. Attached to the wire; 2. Insert the cut terminal wire and semi-finished product into the soft head; 3. Place the lamp in the soft core; 4. Finally, match the soft core and the soft head.

For the combination of the above three or six components, the overall manufacturing process is complicated due to the large number of components.

Another known light string, the structure comprising: LED light-emitting element (bulb), solder, adhesive, wire, plastic film, etc., or further comprising a lampshade The components and the like, and the combination process of the LED light-emitting element (light bulb) and the electric wire includes at least the following steps: 1. First, the electric wire is stripped off part of the insulation to expose the wire; 2. The LED light-emitting element is further removed. The two-wire pin of the (bulb) is matched with the stripped bare wire for solder bonding; 3. a thermoplastic plastic film is wrapped around the solder joint for auxiliary fixing; 4. Reheating is used. The mold wraps the joint of the lower half of the entire LED light-emitting element (bulb) and the wire.

As described above, the structure and assembly of the lamp string are mainly dependent on manual assembly, so that it is not only labor-intensive and time-consuming, but also often prone to human error in assembly, thereby causing a high quality defect rate of the lamp string. The need for components or their assembly processes is relatively high, which also leads to intangible increase in material costs and assembly operations, making manufacturing management more complicated and increasing costs.

The main purpose of the present invention is to provide an LED light string comprising a soft head upper part, a soft head upper part, a wire and an LED light emitting element (which may or may not include a lamp cover), wherein The two wire pins of the LED light-emitting element are pre-bonded (or "welded" by welding to the wire, and then placed between the upper part and the lower part of the soft head, and the upper part and the lower part are placed. The components are welded and combined by ultrasonic waves, so that the wires and the LED light-emitting components can be once bonded to the inside of the soft head, which not only saves material cost and improves assembly yield, but also avoids people. The human error occurred in the assembly of the assembly, so the overall components are more streamlined, the cost can be reduced, and the assembly is easy. It is particularly convenient to cooperate with the mechanical automation to mass-produce the LED light string.

The structural features and other functions and purposes of this creation are described in detail in the following embodiments:

As shown in the embodiment of the present invention, the present invention is an LED light string, which mainly includes: a soft head upper part 1, a soft head lower part 2, an electric wire 3, and an LED light emitting element 4 (with or without a lamp cover 41). The components can be mass-produced by the three-step process, wherein: as shown in the second figure, the two-wire pin 42 of the LED light-emitting component 4 and the wire body 31 of the wire 3 are preliminarily Welded joint (or "fusion welding"), which does not require the use of any solder or adhesive, and does not require the use of a thermoplastic plastic film; as shown in Figures 3 and 4 The above-mentioned forged and welded LED light-emitting element 4 and the electric wire 3 are placed between the soft head upper part 1 and the soft head lower part 2; After the soft head upper part 1 and the soft head lower part 2 are matched and covered, the ultrasonic bonding is performed by ultrasonic welding, and the electric wire 3 and the LED light emitting element 4 are quickly wrapped and bonded to the inside of the soft head 10 (as shown in the first figure), that is, The assembly of the upper soft head part 1, the soft head lower part 2, the electric wire 3, and the LED light emitting element 4 is completed.

The upper soft head member 1 has a housing shape which is not limited in appearance, but has two span grooves 11 which can match the wire body 31 of the electric wire 3, and a joint portion 12 which can match the two wire pins 42 of the LED light-emitting element 4. .

Similarly, the above-mentioned soft head lower part 2 has a housing shape which is not limited in appearance, but also has two straddle recesses 21 which can match the wire body 31 of the electric wire 3, and a wire accommodating and accommodating the LED light-emitting element 4 The joint portion 22 of the foot 42 and the soft head lower member 2 and the soft head upper member 1 can be in a relatively matched hermetic bond.

The upper soft head member 1 and the soft head lower member 2 can be respectively provided with matching corresponding holes 23 and the embedded posts 24 (14) on the oppositely joined end walls, so that the upper soft head member 1 and the soft head lower member 2 After matching the cover, temporary positioning can be obtained for ultrasonic fusion bonding.

The upper soft head member 1 and the soft head lower member 2 may also be respectively provided with corresponding matching rib bodies 25 and fine grooves (not shown) on the respective opposite end walls, respectively. After being combined with the soft under-head component 2 by ultrasonic welding, the ridge body 25 can be more closely combined with the corresponding matching fine groove to obtain a better adhesion fixing effect.

The soft head upper part 1 and the soft head lower part 2 are respectively provided with matching insulating spacer ribs 16 and 26 in the accommodating inner cavity for isolating the lead body 31 of the wires 3 on both sides to avoid short circuit. Contact and soft After the upper head member 1 and the soft head lower member 2 are ultrasonically welded, the bonding strength between the upper head member 1 and the soft head lower member 2 is increased, and a more tight joining effect is obtained. Further, the soft head lower member 2 is adapted to accommodate the insulating spacer ribs 26 of the inner cavity, and further laterally connected transverse ribs 261 for reinforcing the structural strength of the soft under-head member 2, and the soft The upper part 1 is also the same.

As shown in the fifth and sixth figures, the LED light-emitting component 4 described above may include a component of the lamp cover 41 such that the lamp cover 41 is sleeved outside the LED light-emitting component 4, and the open end of the lampshade 41 is relatively matched to The joint portions 12 and 22 of the soft head upper member 1 and the soft head lower member 2 form a seal-locking joint.

In summary, according to the creation of the LED light string structure, it requires only four components, and in particular, the use of forged welding and ultrasonic welding, so that the overall components have been simplified and easy to assemble quickly. They are obviously different from the conventional light string. For this purpose, the application for new type, please give the approval of the patent according to the law, it is a virtue.
