The present disclosure relates to the field of lamp technology, and in particular, to an anti-pull-apart decorative lamp and an anti-pull-apart lamp string.
In an existing landscape decorative lamp, a pin-package light-emitting diode (LED) is usually used as a light source device. A lead wire frame is used as a pin in the pin-package LED. Such a packaging structure is the earliest one developed successfully and put on the market. The packaging structure has many varieties and relatively high technological maturity, and is the most convenient and economical solution in the lamp industry at present. However, in most commercially available decorative lamps using a pin-package LED, the pin-package LED is directly soldered to a power cable. Due to the poor anti-pull capability of solder, in the outdoor environment with strong wind force or when children often pull and play with it, the connection mode of soldering is easy to cause the pin-package LED to fall off from the power cable, exposing a conductive part of the power cable to the air, which is easy to cause the danger of electric shock and pose a threat to personal safety. In addition, pseudo soldering is likely to occur when the pin-package LED is connected by solder tin. As a result, the pin-package LED emits light abnormally, adversely affecting the appearance of a decorative lamp.
The present disclosure aims at solving one of the technical problems in the related art. In view of this, the present disclosure provides an anti-pull-apart decorative lamp and an anti-pull-apart lamp string, which have good anti-pull-apart performance and can prevent the occurrence of pseudo soldering.
According to an embodiment of a first aspect of the present disclosure, an anti-pull-apart decorative lamp is provided including:
a light source including a light-emitting chip and a lead wire frame, the lead wire frame having a first end electrically connected to the light-emitting chip and a second end at which a pin is provided;
a connecting wire including a conducting wire and an insulating layer, the insulating layer covering a side wall of the conducting wire, the conducting wire at one end of the connecting wire protruding from the insulating layer and forming a wiring connector, and the other end of the connecting wire being electrically connected to a drive power supply;
a conductive terminal having a first end provided with a first clip and a second end provided with a second clip, the first clip being roll-pressed against the pin, and the second clip being roll-pressed against the wiring connector; and an insulating plastic surrounding the wiring connector, the pin, and the conductive terminal, the insulating plastic being configured for preventing the pin from short-circuiting and/or electric leakage.
The anti-pull-apart decorative lamp according to the embodiment of the first aspect of the present disclosure at least has the following beneficial effects:
The pin of the lead wire frame is provided on the first clip, and the first clip surrounds the pin and is in tight contact with the pin, so that a frictional force between the first clip and the pin is used to fasten the lead wire frame at one end of the conductive terminal. The wiring connector of the connecting wire is provided on the second clip, and the second clip surrounds the wiring connector and is in tight contact with the wiring connector, so that a frictional force between the second clip and the wiring connector is used to fasten the connecting wire at the other end of the conductive terminal. The conducting wire of the connecting wire is electrically connected to the light-emitting chip of the light source by the conductive terminal. The surfaces of the wiring connector, the pin, and the conductive terminal are covered with the insulating plastic, which can prevent the pin from short-circuiting, prevent the wiring connector, the conductive terminal, and the pin from electric leakage, and can reinforce the connection between the conductive terminal and the pin as well as the wiring connector. The conductive terminal holds the pin and the wiring connector tightly by the first clip and the second clip, so that the anti-pull capability can be improved. In addition, the wiring connector can be electrically connected to the pin without soldering, thereby effectively avoiding pseudo soldering. The anti-pull-apart decorative lamp according to the embodiment of the first aspect of the present disclosure has a simple structure and low manufacturing cost.
In some embodiments of the present disclosure, the conductive terminal is provided with a connecting sheet having one end connected to the first clip and the other end connected to the second clip, and the wiring connector is electrically connected to the pin indirectly by the connecting sheet.
In some embodiments of the present disclosure, a portion of the first clip connected to the connecting sheet is arc-shaped, and two sides of the first clip perpendicular to an axial direction of the conductive terminal bend toward a same surface of the first clip.
In some embodiments of the present disclosure, a portion of the second clip connected to the connecting sheet is arc-shaped, and two sides of the second clip perpendicular to the axial direction of the conductive terminal bend toward a same surface of the second clip.
In some embodiments of the present disclosure, the conductive terminal further includes a third clip, the third clip is connected to an end of the second clip away from the connecting sheet, the second clip is configured for being roll-pressed against the conducting wire near the wiring connector, and the third clip is configured for being roll-pressed against the insulating layer near the wiring connector.
In some embodiments of the present disclosure, a portion of the third clip connected to the second clip is arc-shaped, and two sides of the third clip perpendicular to the axial direction of the conductive terminal bend toward a same surface of the third clip.
In some embodiments of the present disclosure, a length of the first clip in a circumferential direction of the conductive terminal is greater than or equal to a circumferential length of the pin, and a length of the second clip in the circumferential direction of the conductive terminal is greater than or equal to a circumferential length of the conducting wire.
In some embodiments of the present disclosure, a surface of the insulating plastic away from the conductive terminal is wrapped with a plastic layer, and the plastic layer is configured for encapsulating the insulating plastic inside the plastic layer.
In some embodiments of the present disclosure, the conductive terminal is made of copper or a copper-containing alloy.
An anti-pull-apart lamp string according to an embodiment of a second aspect of the present disclosure is provided including a plurality of anti-pull-apart decorative lamps in the embodiment of the first aspect and a cable, the cable being electrically connected to the connecting wire, the cable being provided with a power interface, and the power interface being configured for connecting a drive power supply.
The anti-pull-apart lamp string according to the embodiment of the second aspect of the present disclosure at least has the following beneficial effects:
The cable is provided with the connecting wire which is connected to the pin of the light source by the conductive terminal, so that the light source has a good anti-pull capability, and at the same time pseudo soldering can be avoided. The surfaces of the pin of the light source, the conductive terminal, and the wiring connector of the connecting wire are covered with the insulating plastic, which prevent the pin from short-circuiting, prevent electric leakage, and improve the anti-pull capability. The anti-pull-apart lamp string of the present disclosure can be arranged in occasions with large wind force or a large number of children. Because the anti-pull-apart lamp string of the present disclosure has good anti-pull performance, the light source can be prevented from being pulled off to avoid electric leakage at the cable. The power interface of the cable can be connected to a drive power supply with a voltage higher than the human body safety voltage.

In addition, the conductive terminal 300 is provided with a connecting sheet 330 at a middle of the conductive terminal 300, with one end connected to the first clip 310 and the other end connected to the second clip 320. The first pin 121 and the second pin 122 are tightly clamped by the first clip 130 respectively. The wiring connector 230 of the connecting wire 200 is tightly clamped by the second clip 320. The wiring connector 230 is indirectly electrically connected with a respective one of the first pin 121 and the second pin 122 by the connecting sheet 330. The first clip 310 and the second clip 320 are independent of each other and do not affect each other. When a light source fails and needs to be replaced, it is only necessary to release the first clip 310 without affecting the connection between the second clip 320 and the wiring connector 230, which is convenient for maintenance and mass production. The first clip 310 and the second clip 320 are connected by the sheet-form connecting sheet 330, so that the resistance between the first clip 310 and the second clip 320 can be reduced, and the impact of the conductive terminal 300 on the brightness of the light source 100 can be reduced.
Further, the conductive terminal 300 is made of pure copper or a copper alloy, and the impedance between the light source 100 and the connecting wire 200 is reduced by the good conductivity and ductility of copper, so that the mechanical strength according to this embodiment is enhanced.
In the anti-pull-apart decorative lamp in this embodiment, the first pin 121 and the second pin 122 of the lead wire frame 120 and the wiring connector 230 of the connecting wire 200 are surrounded and tightly clamped by the first clip 310 and the second clip 320 of the conductive terminal 300 respectively, so that it is difficult to pull apart the light source 100 from the conductive terminal 300. Thus, the anti-pull-apart decorative lamp in this embodiment has good anti-pull capability and can avoid potential safety hazards caused by the connecting wire 200 being exposed to the air. It is not necessary to solder the light source 100 and the connecting wire 200 in this embodiment, so that the problem of pseudo soldering caused by soldering is avoided, and abnormal light emission caused by pseudo soldering can be avoided. The surfaces of the portion of the lead wire frame 120 outside the lampshade 130, the conductive terminal 300, and the wiring connector 230 are covered with the insulating plastic 400, so that the anti-pull capability in this embodiment can be further improved, to prevent the first pin 121 and the second pin 122 from being short-circuited due to compression. In addition, these parts can be prevented from discharging electricity to the outside to cause safety hazards. In the anti-pull-apart decorative lamp in this embodiment, the light source 100 may be solderlessly connected to the connecting wire 200, so that no toxic gas is generated during production, thereby reducing pollution to the environment.

Further, a portion of each of the first clip 310 and the second clip 320 connected to the connecting sheet 330 is arc-shaped. A portion of the third clip 340 connected to the second clip 320 is arc-shaped. Two sides of each of the first clip 310, the second clip 320, and the third clip 340 perpendicular to an axial direction of the conductive terminal 300 bend toward a same surface of the first clip 310, the second clip 320, and the third clip 340, to form a V-shaped structure with a curved bottom. Because the first pin 121 and the second pin 122 of the light source 100 as well as the conducting wire 210 and the insulating layer 220 of the connecting wire 200 are cylindrical structures, the first clip 310, the second clip 320, and the third clip 340 with an arc-shaped bottom can be in full contact with the surfaces of the first pin 121, the second pin 122, the conducting wire 210, and the insulating layer 220, to increase the frictional forces between the first clip 310 and the first pin 121 as well as the second pin 122, between the second clip 320 and the conducting wire 210, and between the third clip 340 and the insulating layer 220. Two sides of each of the first clip 310, the second clip 320, and the third clip 340 perpendicular to the axial direction of the conductive terminal 300 bend toward the same surface of the first clip 310, the second clip 320, and the third clip 340 respectively, which facilitates the machine to process the first clip 310, the second clip 320, and the third clip 340, making it easy for the first clip 310 to surround and press-fit on the first pin 121 and the second pin 122, for the second clip 320 to surround and press-fit on the conducting wire 210, and for the third clip 340 to surround and press-fit on the insulating layer 220. Therefore, the anti-pull-apart decorative lamp of this embodiment is applicable to large-scale production, thereby improving the production efficiency.
In addition, a length of the first clip 310 in a circumferential direction of the conductive terminal 300 is greater than or equal to circumferential lengths of the first pin 121 and the second clip 122 and a length of the second clip 320 in the circumferential direction of the conductive terminal 300 is greater than or equal to a circumferential length of the conducting wire 210, so that the first clip 310 and the second clip 320 can at least cover the surfaces of the first pin 121, the second pin 122, and the conducting wire 210 by one lap, which increases the contact areas between the first clip 310 and the first pin 121 as well as the second pin 122 and between the second clip 320 and the conducting wire 210 and thus increases the frictional forces between the first clip 310 and the first pin 121 as well as the second pin 122 and between the second clip 320 and the conducting wire 210, thereby improving the anti-pull capability in this embodiment.
