[First Embodiment]

Referring to FIG. 1 , FIG. 2 a and FIG. 2 b , FIG. 1 is an exploded view of a power socket with a switching function according to a first embodiment of the present invention. 2a is a perspective view of a power socket having a switching function according to a first embodiment of the present invention. 2b is a perspective view of another power supply socket having a switching function according to a first embodiment of the present invention. As shown, the power socket 1 having a switching function includes a first housing 10, a first electrical conductor 12, a switch unit 14, a second electrical conductor 16, a button module 18, and a first electrode 20. The relative relationship and function of each component in the power socket 1 having the switching function will be separately described below.

The first casing 10 has a bottom surface 10a and a side surface 10b. The side surface 10b is penetrated by the first electrode 20, and the first electrode 20 in the first casing 10 is elongated. The first electrode 20 is located above the bottom surface 10a and parallel to the bottom surface 10a such that the first electrode 20 is locked in the first housing 10. Since the first electrode 20 penetrates the side surface 10b of the first casing 10 in the lateral direction (ie, the direction parallel to the bottom surface 10a), the first electrode 20 does not easily fall from the first casing 10. The first housing 10 is configured to securely hold the first electrical conductor 12 , the second electrical conductor 16 , the button module 18 , and the first electrode 20 , and is configured to receive the switch unit 14 . In addition, the first electrode 20 can pass through the two slits 10c on the side surface 10b of the first casing 10. And through the first housing 10. The two slits 10c are located on the same plane and are parallel to the bottom surface 10a. Similarly, since the first electrode 20 penetrates the side surface 10b of the first casing 10 in the lateral direction of the two slits 10c (that is, the direction parallel to the bottom surface 10a), the first electrode 20 does not easily fall from the first casing 10. The first housing 10 can have a spacer element 102 disposed between the first conductor 12 and the first electrode 20 for electrically isolating the first conductor 12 from the first electrode 20. In fact, the first electrical conductor 12 can be attached to the upper surface of the isolation element 102, and the first electrode 20 can be attached to the lower surface of the isolation component 102. The isolation component 102 should be made of an insulating material to enable the first electrical conductor 12. It is insulated from the first electrode 20. Of course, if the first electrical conductor 12 is firmly fixed on the first casing 10 such that the first electrical conductor 12 is located above the first electrode 20 and has a considerable distance without contact, the first casing 10 may be absent. Isolation element 102.

In practice, the first housing 10 and the spacer member 102 may be integrally formed of an insulating material, and the insulating material may be plastic, rubber or other suitable material. In addition, a side portion 10b of the first housing 10 can be a detachable side cover 104. When the side cover 104 is opened, the first electric conductor 12, the switch unit 14, the second electric conductor 16, and the button mold are made.
