As the power strip of the invention comprises a protective housing, and the protective housing is covered outside the power strip body to prevent water or other liquid from splashing into the jacks of the power strip body, thus avoiding water or other liquid entering into the interior of the power strip body through the jacks. Therefore, the power strip of the invention has relatively high safety. ## Claims ### Claim 1 A high-safety power strip comprising: a power strip body, having a plurality of three-hole and/or two-hole jacks for connecting with at least one plug; and a protective housing having an opening at one side thereof, the protective housing being connected with the power strip body, wherein the jacks are located in the protective housing and face an inner wall of the protective housing; wherein the protective housing is connected to the power strip body by at least one joint structure; wherein each of the at least one joint structure comprises a clamping bar arranged on an inner wall of the protective housing, and a slot provided on the power strip body, and the clamping bar is engagable with the slot by means of inserting. ### Claim 2 (depends on 1) The power strip according to claim 1, wherein the power strip body is entirely accommodated in the protective housing. ### Claim 3 (depends on 2) The power strip according to claim 2, wherein the protective housing is in a shape of cuboid with a cavity for receiving the power strip, and the power strip body is in a shape of cuboid. ### Claim 4 (depends on 3) The power strip according to claim 3, wherein each of the jacks has a profile in a shape of square, round or oval. ### Claim 5 (depends on 3) The power strip according to claim 3, wherein the power strip body is parallel to the protective housing in a lengthwise direction, and the jacks are linearly distributed along the lengthwise direction of the power strip body. ### Claim 6 (depends on 5) The power strip according to claim 5, wherein each of the jacks has a profile in a shape of square, and one pair of opposite sides of each jack is parallel to a long side of the power strip body. ### Claim 7 (depends on 5) The power strip according to claim 5, wherein each of the jacks has a profile in a shape of square, and an acute angle is formed between one pair of opposite sides of each jack and a long side of the power strip body. ### Claim 8 A high-safety power strip comprising: a power strip body, having a plurality of three-hole and/or two-hole jacks for connecting with at least one plug; and a protective housing having an opening at one side thereof, the protective housing being connected with the power strip body, wherein the jacks are located in the protective housing and face an inner wall of the protective housing; wherein a plurality of wire-passing gaps are defined on the protective housing, each two adjacent wire-passing gaps are separated by a block part, and the wire-passing gaps are in communication with the opening of the protective housing. ### Claim 9 (depends on 8) The power strip according to claim 8, wherein the protective housing is integrally provided with a plurality of tabs, the tabs are respectively corresponding to the wire-passing gaps, and each of the tabs extends from one block part arranged on one side of the wire-passing gap towards another side of the wire-passing gap and terminates at a central portion of the wire-passing gap. ### Claim 10 (depends on 8) The power strip according to claim 8, further comprising a plurality of wrapping posts arranged on an inner wall of the protective housing or on surfaces of the power strip body. ### Claim 11 (depends on 10) The power strip according to claim 10, wherein the wrapping posts extend towards the opening of the protective housing from the power strip body. ### Claim 12 (depends on 10) The power strip according to claim 10, wherein a plurality of loose-proof outer edges are formed at free ends of the wrapping posts respectively, and the loose-proof outer edges extend from an outer wall of the wrapping post in a direction transverse to the wrapping posts. ### Claim 13 (depends on 10) The power strip according to claim 10, wherein the wire-passing gaps are arranged respectively corresponding to the jacks, and the jacks are arranged corresponding to the wrapping posts respectively. ### Claim 14 (depends on 8) The power strip according to claim 8, wherein the protective housing is in a shape of cylinder with the opening on one end thereof, the power strip body is in a shape of prismoid, and the jacks are distributed circumferentially on a sidewall of the power strip body, an annular space is formed between the sidewall of the power strip body and the inner wall of the protective housing for receiving the at least one plug. ### Claim 15 (depends on 14) The power strip according to claim 14, wherein the power strip body comprises a bottom wall connecting with a bottom circumference of the sidewall, an opening is defined in the bottom wall and a power jack is arranged at the opening of the bottom wall. ### Claim 16 (depends on 8) The power strip according to claim 8, wherein the protective housing is in a shape of cylinder with the opening on one end thereof, and the power strip body is attached to the inner wall of the protective housing, the power strip body defines a space at a central portion thereof for receiving the at least one plug. ### Claim 17 (depends on 16) The power strip according to claim 16, wherein a sidewall of the power strip body is in a shape of prismoid, and the jacks are distributed circumferentially on the sidewall of the power strip body, the power strip body further comprises a bottom flange extending radially outwardly from a bottom circumference of the sidewall to the inner wall of the protective housing. ### Claim 18 (depends on 17) The power strip according to claim 17, wherein the bottom flange defines an opening therein and a power jack is arranged at the opening of the bottom flange.
