The first and the second connecting section are separately downward extended from two opposite ends of the basic section, such that the basic section and the first and second connecting sections together define a receiving space in between them. The contact section is downward extended from a side edge of the basic section into the receiving space; and the first connecting section is outward bent at its lower end to form the grounding section. And, the grounding section is provided at an outer end with a grounding opening. ## Claims ### Claim 1 A grounding structure for power socket, comprising a grounding main body; the grounding main body including a basic section, a first connecting section, a second connecting section, a grounding section, and a contact section; the first and the second connecting section being separately downward extended from two opposite ends of the basic section, such that the basic section and the first and second connecting sections together define a receiving space in between them; the contact section being downward extended from a side edge of the basic section into the receiving space; the first connecting section being outward bent at its lower end to form the grounding section; and the grounding section being provided at an outer end with a grounding opening. ### Claim 2 (depends on 1) The grounding structure for power socket as claimed in claim 1, wherein the basic section includes a middle horizontal portion and two inclined portions outward and downward extended from two opposite ends of the horizontal portion to correspondingly connect to upper ends of the first and second connecting sections; and the contact section being downward extended from a side edge of the horizontal portion of the basic section. ### Claim 3 (depends on 2) The grounding structure for power socket as claimed in claim 2, wherein the contact section is provided at a lower end with an opening that extends through the contact section in a thickness direction thereof. ### Claim 4 (depends on 3) The grounding structure for power socket as claimed in claim 3, wherein the contact section is downward extended from the lower end to provide a grounding section. ### Claim 5 (depends on 4) The grounding structure for power socket as claimed in claim 4, wherein the first and the second connecting section include a first lug and a second lug, respectively; the grounding section being processed at a joint between it and the first connecting section to form an elongated slot, such that material from the slot is downward bent to form the first lug; and the second lug being downward extended from a lower end of the second connecting section and being located corresponding and parallel to the first lug. ### Claim 6 (depends on 5) The grounding structure for power socket as claimed in claim 5, wherein the grounding section is connected at an inner end to the lower end of the first connecting section and is further provided near the outer end with a locating tab, which is downward extended from a side edge of the grounding section at a position adjacent to the grounding opening. ### Claim 7 (depends on 3) The grounding structure for power socket as claimed in claim 3, wherein the first and the second connecting section are formed on each of their two opposite side edges with a first and a second make-way slot, respectively; at a lower end of each of the first make-way slots, there being a first stop member integrally formed with the first connecting section, such that a free upper end of the first stop member is elastically movable in the first make-way slot; and similarly, at a lower end of each of the second make-way slots, there being a second stop member integrally formed with the second connecting section, such that a free upper end of the second stop member is elastically movable in the second make-way slot. ### Claim 8 (depends on 3) The grounding structure for power socket as claimed in claim 3, wherein the grounding main body is made of a metal material; and the basic section, the first and second connecting sections, and the grounding section are integrally formed to constitute the grounding main body. ### Claim 9 (depends on 3) The grounding structure for power socket as claimed in claim 3, wherein the grounding section is configured to engage with a corresponding metal-made carrier; and the grounding section being fixedly and electrically connected to the carrier via a fastening element that is extended through the grounding opening provided on the outer end of the grounding section into the carrier. ### Claim 10 (depends on 1) The grounding structure for power socket as claimed in claim 1, wherein the grounding structure is configured for mounting onto a power socket; the power socket including: a socket main body, onto which the grounding main body is mounted, including an inner insertion space, a forward-opened outer shell that internally defines the insertion space, and a plurality of first conducting terminals; the shell being received in the receiving space defined in the grounding main body; the first conducting terminals being located in the insertion space in the shell and respectively having a rear end rearward extended from the insertion space through the socket main body to project beyond a rear outer surface of the shell; and the contact section of the grounding main body being electrically connected to the rear end of one of the first conducting terminals; and a plurality of second conducting terminals being disposed on the rear outer surface of the shell; and upper ends of the second conducting terminals being correspondingly electrically connected to the rear ends of the first conducting terminals. ### Claim 11 (depends on 10) The grounding structure for power socket as claimed in claim 10, wherein the first and the second connecting section of the grounding main body are formed on each of their two opposite side edges with a first and a second make-way slot, respectively; at a lower end of each of the first make-way slots, there being a first stop member integrally formed with the first connecting section, such that a free upper end of the first stop member is elastically movable in the first make-way slot; and similarly, at a lower end of each of the second make-way slots, there being a second stop member integrally formed with the second connecting section, such that a free upper end of the second stop member is elastically movable in the second make-way slot. ### Claim 12 (depends on 11) The grounding structure for power socket as claimed in claim 11, wherein the shell of the socket main body is provided on one of its two lateral outer surfaces with two axially spaced first slide channels and on the other lateral outer surface with two axially spaced second slide channels corresponding to the two first slide channels; and the two opposite side edges of the first connecting section of the grounding main body being correspondingly slid through the two first slide channels and the two opposite side edges of the second connecting section of the grounding main body being correspondingly slid through the two second slide channels when the grounding main body is fitted onto the shell of the socket main body, such that the free upper ends of the first and second stop members abut on lower ends of the first and second slide channels, respectively.
