Abstract

The invention discloses an all-in-one stereo socket, comprising an housing, wherein the housing is in the shape of a cube with adjacent faces transitioned spherically; the housing has a top face provided with a power switch and a USB jack, three continuous side faces provided with three-prong outlet modules each having an outlet, another side face provided with a power line, and a bottom face acting as a support face; the housing is internally provided with a circuit board and a support frame assembly; the circuit board is provided with a USB plugging terminal corresponding to the USB jack; the support frame assembly is internally provided with live-line conductive terminals, null-line conductive terminals and grounding conductive terminals, which are arranged corresponding to respective outlets; and the back face of each three-prong outlet module is provided with a protective door device fixed to the support frame assembly.

Claims

1. An all-in-one stereo socket, comprising a housing, characterized in that the housing is in the shape of a cube provided with six faces, with adjacent faces transitioned spherically;

the housing has a top face provided with a power switch and a USB jack, three continuous side faces provided with three-prong outlet modules each having an outlet, another side face provided with a power line, and a bottom face acting as a support face;

the housing is internally provided with a circuit board and a support frame assembly;

the circuit board is provided with a USB plugging terminal corresponding to the USB jack;

the support frame assembly is internally provided with live-line conductive terminals, null-line conductive terminals and grounding conductive terminals, which are arranged corresponding to respective outlets; and

the back face of each three-prong outlet module is provided with a protective door device fixed to the support frame assembly;

the support frame assembly is internally provided with live-line conductive strips, null-line conductive strips and grounding conductive strips;

the respective live-line conductive terminals and live-line conductive strips are in an all-in-one structure;

the respective null-line conductive terminals and null-line conductive strips are in an all-in-one structure; and

the respective grounding conductive terminals and grounding conductive strips are in an all-in-one structure;

the support frame assembly comprises a first support block, a second support block, a third support block and a fourth support block, which are arranged from top to bottom in turn;

the first support block and the fourth support block are fixed in a buckling way; and

the second support block and the third support block are clamped and fixed between the first support block and the fourth support block;

the live-line conductive strips are fixed between the first support block and the second support block;
