In a conventional multi-tap outlet, parts for power supply and grounding, such as power terminals and power cables, are all assembled and built in an open structure inside the main body, so all the parts inside the main body must be assembled at once. Therefore, there is a problem in that assembly and productivity are inferior.

In addition, safety is also inferior because the power connection part is entirely protected by the case of the main body.

In other words, unlike a wall-mounted outlet, the main body is exposed to the outside space and can be used, so safety is inevitably less than that of a wall-mounted outlet. Since a separate protection device is not provided, there is a problem that not only easily breaks down, but also has a large risk of safety accidents.

Accordingly, the present invention was devised to solve the above problems,

The power module with built-in power terminal is modularized separately from the case of the main body, so that the assembly is excellent.At the same time, the electrical connection part of the power terminal and the ground terminal is built-in in an insulated body that is separately connected to the inside of the main body.

The upper plate 40 includes a receiving groove 44a in which a conductor of a power line is received at a position corresponding to the first fastening hole 53, and a dome-shaped cover part 44 covering an upper portion of the receiving groove 44a. Including ), the end of the conductive wire that is fitted in contact with the connection part 32 is protected by the cover part 44 to prevent exposure to the outside of the insulating body (I).
The method of claim 1,
The main body M includes a first coupling column 12 protruding from the upper surface of the upper case 10 to the lower side and having a first screw hole 12a,
The insulating body (I) is provided in the upper plate (40), the through hole (43) through which the first coupling column (12) is inserted, protrudes upward from the lower surface of the lower housing (50), and the first coupling Including a first coupling portion 52 having a first inner hole (52a) into which the end portion of the pillar 12 is fitted,
An outlet, characterized in that a bolt fitted from a lower portion of the first internal hole 52a is screwed into the first screw hole 12a, so that the main body M and the power module P are coupled.
The method of claim 1,
The power module (P) is provided on the upper surface of the upper plate (40) of the insulating body (I), the ground pin (61) exposed to the inside of the socket (11), and inserted into the inside of the insulating body (I) An outlet, characterized in that the grounding portion (62) is embedded in the insulating body (I), further comprising a ground terminal (60) having a grounding portion (62) to which a ground wire is connected.
The method of claim 3,
The insulating body (I) is provided with an exposed groove (45) in the upper plate (40) into which the ground part (62) is inserted,
The main body (M) is connected to protrude from the upper surface of the upper case 10 to the lower side to seal the exposed groove (45) and a blocking portion (18), and the ground portion protruding from the inner surface of the blocking portion (18). An outlet, characterized in that it comprises a support end (18a) for supporting the 62 so as not to be pushed outward.
