As shown in the first and second figures, the socket extension cord 100 of the present invention comprises a socket panel 110, a contact portion 120, a socket body 130 and a base 140 for waterproofing and protection against electric shock.

In detail, the socket panel 110 has at least one pair of jacks 112 and at least one switch 114 corresponding to at least one pair of jacks 112. For example, in the embodiment shown in the first and second figures, the socket panel 110 has four pairs of jacks 112 and four switches 114 corresponding to the four pairs of jacks 112.

As shown in the second and sixth figures, the contact portion 120 is disposed under the socket panel 110, and has two terminals 122 corresponding to the pair of jacks 112, two conductive copper sheets 124 disposed opposite the two terminals 122, and two insulation pushes. Block 126 and two metal sheets 128. In addition, the socket body 130 has a receiving space 132 corresponding to each of the pair of jacks 112 to accommodate the contact portion. 120, and the base 140 is adapted to cooperate with the socket panel 110 to receive the contact portion 120 and the socket body 130 in the manner of the upper and lower joints.

The arrangement relationship between the two terminals 122, the two conductive copper sheets 124, the two insulating push blocks 126, and the two metal sheets 128 will be described below.

Referring to the sixth and seventh figures, the two metal pieces 128 are respectively disposed above and below the accommodating space 132, and the insulating push blocks 126 are disposed between the terminals 122 and the metal pieces 128, and It is in contact with each terminal 122. In addition, one end of each conductive copper piece 124 is in contact with the insulating push block 126, and the other end of each conductive copper piece 124 is disposed adjacent to the other of the terminals 122 and is not in contact with the other of the terminals 122. At this time, there is a gap 150 between the conductive copper sheet 124 and the metal sheet 128 at the upper end, so that the conductive copper sheet 124 and the metal sheet 128 can be in a non-conducting state.

Therefore, as shown in the eighth and ninth diagrams, when one of the plug conductive portions 150 is inserted between the pair of terminals 122, the terminal 122 is opened, and the upper and lower insulating pushers 126 are respectively turned toward The two conductive copper sheets 124 are pushed outward to make the two conductive copper sheets 124 contact with the upper and lower ends of the metal sheets 128 to conduct electricity (as indicated by arrows A and B), so that the socket extension cord 100 and the plug conductive portion of the present invention are made. 150 is in a conducting state.

On the other hand, as shown in the tenth and eleventh figures, when a foreign object 200 is inserted into the terminal 122 at the upper end, since only the terminal 122 of the upper end is opened, the insulating pusher 126 of the upper end is pushed outward. The conductive copper piece 124 is such that one end (upper end) of the upper conductive copper piece 124 is in contact with the upper metal piece 128, and one end (upper end) of the lower conductive copper piece 124 is in contact with the upper end terminal 122 (as indicated by the arrow A) Wherein the other end (lower end) of the upper conductive copper piece 124 is not in contact with the lower end terminal 122, and the other end (lower end) of the lower conductive copper piece 124 is not in contact with the lower end metal piece 128. Clearance (as indicated by arrow B), so the socket extension line 100 at this time It does not form electricity, but can be used as a protection to prevent electric shock.

Therefore, in the embodiment, the conductive copper sheet 124 is preferably a U-shaped conductive copper sheet, and the two conductive copper sheets 124 are disposed between the two metal sheets 128 in a partially overlapping manner.

On the other hand, for the purpose of waterproofing, as shown in the second figure, in addition to a switch waterproof cover 116 may be covered on each switch 114, as shown in the fourth and fifth figures, the capacity of the socket body 130 may be A bottom portion 134 is disposed in the space 132, and the bottom portion 134 is provided with a plurality of drain holes 136 to assist in discharging the socket extension cord 100 to the outside of the socket body 130 when inadvertently invaded by water or other liquid.

In addition, the contact portion 120 of the socket extension cord 100 of the present invention is electrically connected to the switch 114 by the two metal sheets 128, and preferably, the two metal sheets 128 are integrally formed with the two terminals of the switch 114. In this way, the welding method can be omitted compared to the connection made by the welding method, and the manufacturing cost can be further saved.

It should be noted that, as shown in the third figure, although in the present embodiment, the four pairs of jacks 112 and the four switches 114 of the outlet extension cord 100 are arranged in parallel, it is not limited thereto. . In other words, the four pairs of jacks 112 and the switches 114 of the socket extension cord 100 of the present invention can also be arranged in series as shown in FIG.

In summary, since the socket extension cord 100 of the present invention has the arrangement of the switch waterproof sleeve 116, the drain hole 136 and the special contact portion 120, it is capable of both waterproofing and electric shock prevention.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of this creation shall be included in the scope of the appended patent application.
