Description

  The present invention relates to a Christmas rope bulb, and more particularly to a Christmas rope bulb capable of appropriately extending a length.

  A clause such as Christmas decorates a Christmas rope bulb on a Christmas tree, a building or other ornaments, emits various light colors from the Christmas rope bulb, and improves the fun of the clause. However, the electricity supplied to the Christmas rope bulb must be supplied to the bulb after being stepped down by a transformer in order to prevent burning due to excessive voltage.

  Typically, a transformer steps down a voltage of 120 or 240 volts (V) to 24 volts (V) before supplying electricity to the Christmas rope bulb. However, the low voltage limits the number of bulbs that can be attached to a Christmas rope bulb and the length of the Christmas rope bulb. Thus, to decorate a slightly longer Christmas rope bulb, multiple sets of Christmas rope bulbs must be connected to multiple independent power sources, respectively. For this reason, it is not convenient, and the user is forced to purchase an extra power supply device, which wastes money.

  It is a main object of the present invention to provide a kind of Christmas rope light bulb which is intended to extend its length by connecting a plurality of wires with a special structure.

The structure and features of the present invention will be described in detail as follows, together with a schematic diagram of a preferred embodiment.
1 and 2 show a Christmas rope bulb 100 according to an embodiment of the present invention. It mainly comprises a front power plug 10, a first power cord 20, a rear power socket 30, a second power cord 40, a transformer 50, and a few light bulbs 60. Among them, the front power plug 10 includes a plug housing 11 and a conductive terminal unit 12. The plug housing 11 uses an insulating member, and the conductive terminal unit 12 uses a conductive member. In this embodiment, the conductive terminal unit 12 uses two conductive plates. One end thereof is attached to the inside of the plug housing 11, and the other end forms a predetermined shape and is exposed to the outside of the plug housing 11. The conductive terminal unit 12 in this embodiment uses two conductive plates. However, if necessary, the shape of three conductive plates or other plug plates may be formed.

One end of the first power cord 20 is electrically connected to the conductive terminal unit 12 inside the front power plug 10, and the electricity of the conductive terminal unit 12 is conducted to the first power cord 20.
The rear power socket 30 includes a socket housing 31 and a conductive socket (not shown). The socket housing 31 uses an insulating member, and the conductive cradle uses a conductive member, and is provided in the socket housing 31. A socket hole unit 311 is provided at one end of the socket housing 31, and the free end of the first power cord 20 is electrically connected to the conductive cradle from the other end of the socket housing 31 through the inside of the socket housing 31. Electricity introduced from the front power plug 10 is supplied to the conductive cradle via the conductive terminal unit 12 and the first power cord 20. In this embodiment, the socket hole unit 311 of the socket housing 31 uses two socket holes, but other internationally accepted standards may be used.

One end of the second power cord 40 is inserted into the front power plug 10 and electrically connected to the conductive terminal unit 12.
The transformer 50 is provided in the second power cord 40 to step down the voltage flowing through the second power cord 40.

  The light bulb 60 is electrically connected to the second power cord 40 in a predetermined shape. The transformer 50 is brought closer to the front power plug 10 than the light bulb 60, and the electricity introduced from the front power plug 10 is stepped down by the transformer 50 and then passed through the second power cord 40. The light bulb 60 is supplied. Among them, the light bulb 60 is electrically connected to the second power cord 40 in parallel or in series as necessary.

The long distance installation shown in FIG. 3 connects two sets of Christmas ropes 100 by the following method.
First, a second set of Christmas rope bulbs 100 ′ is prepared, and the conductive terminal unit of the second set of front power plugs 10 ′ is inserted into the socket hole unit 311 of the first set of rear power sockets 30. The two sets of conductive terminal units and the first set of conductive cradle are electrically connected to be electrically connected to the first set of Christmas rope bulb 100 and the second set of Christmas rope bulb 100 '.

  Since the second set of Christmas rope bulbs 100 'is inserted into the rear power socket 30 of the first set of Christmas rope bulbs 100, the length of the two sets of Christmas rope bulbs 100, 100' is extended. Prepare for long distance use by users.

  Since the first set of light bulbs 60 is stepped down from 110 V or 220 V to 24 V by the transformer 50 and is electrically supplied to each light bulb 60 via the second power cord 50, each light bulb 60 is caused by an excessive voltage. Prevent burnout. On the other hand, electricity from the second set of Christmas rope bulbs 100 ′ is supplied from the first power cord 20 provided in the first set of Christmas rope bulbs 100. Since this power supply is not stepped down, it has a high voltage (110 V or 220 V). Therefore, the light bulb 60 'of the second set of Christmas rope bulbs 100' is stepped down by the transformer 50 'connected to the second set of Christmas rope bulbs 100' and then supplied to the bulb 60 'to emit light.

The Christmas rope light bulb of the present invention is a second set of Christmas rope light bulbs that are connected to the rear power socket without stepping down some of the electricity, in addition to providing and emitting light to each light bulb after stepping down some of the electricity introduced. By supplying the same power source, the number and length of light bulbs that can be installed are increased, and the convenience of the user is improved.
As shown in FIG. 3, a third set of Christmas rope bulbs 100 ′ or a fourth set and a fifth set of Christmas rope bulbs may be added.
