Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a power plug with a decorative light (hereinafter, referred to as a power plug unless otherwise specified) for connecting a decorative light arranged on a Christmas tree to a power source, for example.

[0002]

[Prior art]

 As such a power plug, one in which an electric wire connected to a decorative light is connected to two terminal boards and one end of the terminal board is exposed near the terminal boards and a separate plug body is assembled is known. ing.

[0003]

[Problems to be solved by the device]

 However, since the conventional power plug simply supplies an alternating current to the decorative light, there is a problem that electrical noise when the decorative light blinks flows to the outside through the terminal board.

The present invention has been made in view of the above circumstances, and provides a power plug with a decorative light that can prevent electrical noise from flowing to the outside and can reduce the manufacturing cost. The purpose is to provide.

[0005]

[Means for Solving the Problems]

 The power plug according to claim 1 of the present application includes a plurality of decorative electric lights, electric wires connecting these decorative electric lights, two terminal plates respectively attached to the ends of the electric wires, and these terminals. In a power plug equipped with a plate and a plug body that covers a part of the electric wire, connect a fuse and a capacitor in series between the terminal plates in this order, and place the capacitor at least behind the inner end of the terminal plate. It is characterized in that the plug body is integrally formed by resin molding so as to cover a part of the terminal plate, the fuse and the capacitor.

[0006]

[Embodiment of device]

 The power plug of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the power plug 1 includes two terminal plates 2 and 3, electric wires 4,5 to which these terminal plates 2 and 3 are connected, and these terminal plates 2 and 3 and A plug main body 6 that covers a part of the electric wires 4 and 5 is provided, and a plurality of decorative lamps 7 are connected to the electric wires 4 and 5.

As shown in FIGS. 2A and 2B, a fuse 8 and a capacitor 9 are serially connected in this order between the terminal plates 2 and 3. The capacitors 9 and fuses 8 are arranged so as to be located behind the inner ends 2a and 3a of the terminal plates 2 and 3 (that is, on the electric wires 4 and 5 side).

The plug body 6 is provided in a mold (not shown) having two inner ends 2a and 3a of the terminal plates 2 and 3, the electric wires 4 and 5, the fuse 8 and the capacitor 9 opened. The plug body 6 is integrally formed so as to cover a part of the terminal plates 2 and 3, the fuse 8 and the capacitor 9 by so-called resin molding in which resin is injected into the mold.

In order to prevent the capacitor 9 from being exposed from the resin-molded plug main body 6 which is disposed on one side of the mold during resin molding, a supporting pin (not shown) is provided from each mold. ) Is projectingly arranged so as to support the capacitor between these support pins in the center of the cavity between the molds. Reference numeral 10 in FIG. 2 indicates a hole formed by the support pin.

Further, in order to release the resin-molded plug body 6 from the mold, a release pin (not shown) arranged between the terminal plates 2 and 3 in parallel with the terminal plates 2 and 3. I try to push it out. Reference numeral 11 in FIG. 2 indicates a hole formed by the release pin. Since the capacitor 9 is arranged rearward of the inner ends 2a and 3a of the terminal plates 2 and 3, the capacitor 9 and the release pin do not interfere with each other.

The mold has a shape such that a recess 6 a is formed on the outer surface of the plug body 6 corresponding to the space between the terminal plates 2 and 3 and the capacitor 9. Since the recessed portion 6a serves as a fingerhold when the plug 1 is inserted and removed, it is easy to use. Since the capacitor 9 is arranged behind the inner ends 2a and 3a of the terminal plates 2 and 3a, the recess 6a can be easily formed without interfering with the capacitor 9.

According to the power plug of the present embodiment, the action of the capacitor 9 prevents electrical noise due to the lighting of the decorative light 7 from flowing to the outside.

[0014]

[Effect of device]

 As described above, according to the power plug according to claim 1 of the present application, a plurality of decoration lights, electric wires connecting these decoration lights, and 2 attached to the ends of the electric wires, respectively. In a plug with a decorative light, which comprises a number of terminal plates and a plug body that partially covers these terminal plates and electric wires, a fuse and a capacitor are connected in series between the terminal plates in this order, and at least The capacitor is placed behind the inner edge of the terminal board, and the plug body is integrally molded by resin molding to cover a part of the terminal board, the fuse and the capacitor. Can be prevented from flowing to the outside, and since it is a resin mold, it is not necessary to assemble parts and the manufacturing cost can be reduced.
