## Abstract

A power plug adapted for being assembled by a jig which defines a plurality of receiving holes therein and an engaging portion formed on each of the receiving hole, includes a main body defining a passageway and having a basic portion, a terminal received in the passageway and having a soldering piece extending out from the main body, a fixing element inserted into the passageway, a shell and a holding element. The basic portion defines a positioning portion on an outer surface thereof. The shell surrounds the main body and the basic portion extends out of the shell. The holding element has a surrounding portion clasping the shell. When the power plug is disposed in the receiving hole of the jig, the positioning portion is engaged with the engaging portion for preventing the power plug rotating in the receiving hole.

## Claims

### Claim 1

A power plug adapted for being assembled by a jig which defines a plurality of receiving holes therein and an engaging portion formed on each of the receiving holes, comprising:
a main body defining a passageway passing therethrough along the axis of the main body, the main body having a basic portion, a positioning portion formed on an outer surface of the basic portion;
a terminal received in the passageway of the main body, the terminal having a soldering piece extending out from the basic portion of the main body for being soldered with a cable;
a fixing element inserted into the passageway for fixing the terminal in the main body;
a shell partially surrounding the main body, the basic portion of the main body extending out of the shell; and
a holding element having a surrounding portion for clasping the shell and a holding portion for holding the cable therein,
wherein when the power plug is disposed in the receiving hole of the jig, the positioning portion is engaged with the engaging portion for preventing the power plug from rotating in the receiving hole.

### Claim 2 (depends on 1)

The power plug as claimed in claim 1, wherein the positioning portion is protruded from the outer surface of the basic portion.

### Claim 3 (depends on 1)

The power plug as claimed in claim 1, wherein the passageway includes an inserting hole defined in the basic portion, two opposite sides of the inserting hole are arc-shaped, the fixing element has a fixing portion fastened in the inserting hole, and two opposite sides of the fixing portion are arc-shaped corresponding to the inserting hole.
