Description

Swivel Conductive Device This invention relates to a structural design for
a conductive construction, particularly to a freely rotatable swivel conductive device.
The conventional electronic appliance or equipment is connected to a power cord for supplying power that is plugged into a socket supplying power by a plug provided at an end thereof. The conventional power cords and plugs are mostly affixed to each other.
Due to the rigid material for making the plug and the pliable material for making the power cord, after the plug is plugged into the socket, the power cord may be bent or twisted along with the movement of the electronic equipment (such as vacuumed cleaners, hair blowers and electronic hand tools). Prolong exposures to such twisting may cause fracturing or damages of the power cords, or failure of the electronic equipment, and occurrences of electrical hazards.
For better appearance, safety and full utilisation of space, a plug with a flat plug housing (where the prongs are normal to the plug) such that the power cord is situated to be parallel to the socket panel (such as the wall surface). However, such plugs can only be implemented in sockets of two units in series but not three or more units in parallel (because the power cords may interfere with each other). Furthermore, on the sockets having three units in parallel (such as an extension cord), the conventional design would affect the other units such as adapters and chargers thereby resulting in inconvenience.
To eliminate the hazards, damages or inconvenience caused by the conventional power cords or sockets, modified plugs and sockets are thus needed.
It is a primary object of this invention to provide a swivel conductive plug or a swivel conductive socket capable of preventing power cords from bending or twisting due to movement of electronic equipment, where prolong exposures to such twisting may cause fracturing or damages to the power cords.
To achieve the above object, this invention provides a swivel conductive device, comprising: a swivel conductive device including a ground wire swivel pin provided at an end thereof with a ground wire contact portion; a first insulator stand a having swivel disc, a swivel disc having a central bore, a first conductive metal notch and second conductive metal notch, a ground wire contact portion receiving support provided at an upper part thereof, a first protrusion provided at a lower part thereof, a ground wire swivel pin passing through the bore, a ground wire contact portion leaning against the ground wire contact portion receiving support; a first conductive metal having a first annular flange and engaging over the first protrusion, a first flange inserting through the first conductive metal notch; a second insulator stand having a swivel disc, a swivel disc having a central bore, wherein the bore perimeter is formed with a third conductive metal notch, and an annular groove formed between the bore and the swivel disc periphery, a second protrusion provided at a lower part thereof, the annular groove engaging over the first protrusion of the first insulator stand; a second conductive metal having a second annular flange engaging over the second protrusion, a second flange inserting through a third conductive metal notch and a second conductive metal notch.
These and other modifications and advantages will become even more apparent from the following detailed description of a preferred embodiment of the invention by way of example and from the drawings in which: Fig. 1 is an exploded view illustrating the structure of the first embodiment of this invention; Figs. 2 to 11 are schematic views illustrating the assembly of the first embodiment of this invention; Fig. 12 is a schematic view illustrating the first embodiment of this invention; Fig. 13 is an exploded view of the second embodiment of this invention; Fig. 14 is an assembled, perspective view of the second embodiment of this invention; and Fig. 15 is an assembled, perspective view of the third embodiment of this invention.

The swivel disc 121 is provided at an upper part thereof with a ground wire contact portion receiving support 122 and a first protrusion 126 at a lower part thereof. A ground wire swivel pin 11 passes through the bore 125. A ground wire contact portion 111 leans against the ground wire contact portion receiving support 122.
A first conductive metal 13 of an annular shape, includes a first flange 131 and an annular bore 132 and engages over the first protrusion 126. The first flange] 3 l inserts through the first conductive metal notch 123.
A second insulator stand 14 includes a swivel disc 145, a swivel disc 145 having a central bore 143, the bore 143 perimeter being formed with a third conductive metal notch 141 and an annular groove 142 located between the bore 143 and the swivel disc periphery. The swivel disc 145 is provided at a lower part thereof with a second protrusion 144. The annular groove 142 engaging over the first protrusion 126 of the first insulator stand 12.

The second flange 151 inserts through the third conductive meta] notch 141 and the second conductive metal notch 124, such that the first flange 131 of the first conductive metal 13, the second flange 151 of the second conductive metal 15, and ground wire contact portion 111 are exposed out of the first insulator stand 12.
Figs. 2 to 11 are schematic views illustrating the assembly of the first embodiment of this invention. As shown, the ground wire 21 of the power cord 2 is connected to the ground wire contact portion 111. The ground wire swivel pin 11 is placed in the bore of the first insulator stand 12 (see Fig. 2). The first conductive metal 13 then engages over the first protrusion 126 and the first conductive metal notch 123 (see Fig. 3). The neutral wire 22 is electrically connected to the bore 132. The second insulator stand 14 engages over the first protrusion 126 of the first insulator stand 12 (see Fig. 4).

The ground wire conductive copper 4 engages over a tail end of the ground wire swivel pin 11 (see Fig. 8) A bottom lid 25 then covers the ground wire conductive copper 4. A long prong 261 passes through a long insulating hollow column 251 to engage the first conductive ring 16. A short prong 262 passes through a short insulating hollow column 252 to engage the second conductive ring 17 (see Fig. 9). A lateral cover 5 then covers the swivel conductive device, which is then fused by ultrasonic waves (see Fig. 10), where the final product is as shown in Fig. 11.
Fig. 12 is a schematic view illustrating the first embodiment of this invention. As shown, during rotation of the power cord 2, the ground wire 21, neutral wire 22 and live wire 23 would be rotated coaxially with the first conductive metal 13, second conductive metal 15 and ground wire swivel pin 11 driven by the top lid 24. The first conductive ring 16 and second conductive ring 17 can be electrically connected to the first conductive metal 13 and second conductive metal 15, respectively, via their perimeters. Accordingly, even if the power cord 2 is rotated to any orientation, the power cord 2 would not be twisted or fractured due the affixation of the long prong 261 and short prong 262 to the socket.
