The power outlet plug according to the present embodiment is attachable to and detachable from a cylindrical body 100, an electrode portion provided on the body 100, and a spacer attachment portion 700 provided on a side surface of the body 100 from the tip side. The spacer 500 is attached to the spacer 500. The diameter of the body 100 is adapted to various lighter sockets by changing the mounting position of the spacer 500 in the spacer mounting portion 700.

The cylindrical body 100 is composed of two semi-cylindrical members 110A and 110B and a cap 120 that is screwed to the tip of the two semi-cylindrical members 110A and 110B in a combined state. There is. The two semi-cylindrical members 110A and 110B are provided with a locking portion 140 and a locking claw 150 for assembling them. Further, the semi-cylindrical members 110A and 110B are provided with openings for exposing a side surface electrode 300 and a spacer 500 described later in a combined state. The rear end of the body 100, that is, the side from which the power cord 600 is pulled out is formed thicker than other portions so that the power outlet plug can be easily inserted and removed.

Further, the tips of the semi-cylindrical members 110A and 110B are formed to be thinner than the other portions, and male threads are formed on the outer periphery thereof. That is, when the two semi-cylindrical members 110A and 110B are combined, the distal end constitutes one male screw portion, and the cap 120 is screwed.

As described above, in the semi-cylindrical members 110A and 110B that form the body 100, the two mounting grooves 710 and 720 that become the spacer mounting portion 700 into which the spacer 500 is inserted and mounted in the combined state. Is provided. The spacer mounting portion 700 has an opening in a narrowed portion on the front end side of the body 100, and the spacer 500 is adapted to be attached / detached from the front side of the body 100. Further, the cap 120 is screwed into the male screw portion so as to cover the mounting grooves 710, 720 and the spacer 500 mounted therein. The inner first mounting groove 710 is set to correspond to the domestic car, and the outer second mounting groove 720 is set to correspond to the inner diameter of the lighter socket of the foreign car.

A through hole 121 is formed in the cap 120, which is screwed into the male screw portion at the tip of the body 100, for allowing the tip electrode 200 to project, and the surrounding portion of this through hole 121 is more than other portions. It is thinly formed. This is because the size of the bimetal switch (not shown) built into the lighter socket is taken into consideration, and it is set slightly thinner than the smallest bimetal switch. Therefore, there is no risk of damaging the bimetal switch when inserted into any lighter socket.

A tip electrode 200 forming an electrode portion projects from a cap 120 screwed to the tip of the body 100. The tip electrode 200 covers the terminal portion of the fuse 400 and is formed in a substantially convex shape in cross section. The fuse 400 is connected to the substantially forked terminal 410.

That is, the side surface side of the spacer 500 is formed as a gently curved surface. Further, the long side portion of the spacer 500 is slightly bent toward the outside to form a brim portion 510 for fitting into the above-mentioned mounting grooves 710, 720.

To change the diameter of the body 100 to correspond to the lighter socket, first remove the cap 120 and pull out the spacer 500 from the spacer mounting portion 700. In the case of a domestic car, the spacer 500 is inserted into the inner first mounting groove 710 (see FIGS. 5A and 1), and in the case of a foreign car, it is inserted into the outer second mounting groove 720 ( (See FIGS. 5B and 4). By changing the mounting position of the spacer 500 in this way, the diameter of the body 100 can be changed.

In the power outlet plug configured as described above, the side electrode 300 is inserted into the lighter socket while being depressed inside the body 100, and the tip electrode 200 is attached to the electrode provided on the inner side of the lighter socket and the side electrode. The electrodes 300 contact the electrodes provided on the side surface of the lighter socket.

In the above-described embodiment, the spacer mounting portion 700 is provided with the two mounting grooves 710 and 720, but by providing three or more mounting grooves, various lighter sockets can be used. It is also possible to respond in detail.

Further, in the above-described embodiment, the diameter of the body 100 is changed by providing one spacer and two mounting grooves, but there is one mounting groove and a plurality of types having different height dimensions. The same effect can be obtained even if the spacers are prepared.
