  The present invention relates to a power connector, and more particularly, to a power connector that can perform electrical conduction, conversion, or other functions when inserted into a power outlet.

  Conventionally, a general electric product is connected to a power outlet or other power outlet through an electric plug or transformer or other converter, and receives a predetermined form of electricity. Such electrical plugs or transformers or other converters are generally called power connectors, but usually consist of a body part and a plug part with one end connected to one end of the body part. In addition, the connection between the main body portion and the plug portion turns and becomes a pair, for example, the rear end portion of the plug portion is inserted between a pair of left and right protrusions formed at the front end of the main body portion, and there Some of them are sandwiched between the pair of left and right projections and pivoted back and forth so that they can be deformed depending on the location of a power outlet or other power outlet and are convenient for use.

  The deformable power supply connector described above can be easily used even when the space is narrow due to its deformation. However, as described above, since the plug part is provided at one end of the main body part, The center of gravity of the entire unit is not near the connection point of the plug unit with the power outlet, but is biased toward the main unit. Therefore, there is a high possibility that stress is applied to the plug portion to cause poor contact between the plug portion and the power outlet, or the plug portion is detached from the power outlet and the entire power connector is dropped and broken.

  In view of the above, the present invention provides a power connector that not only allows the plug part to rotate with respect to the main body part, but also moves the connecting position of the main body part with the plug part and adjusts the position of the center of gravity during use. The purpose is to provide.

  In order to achieve the above-mentioned object, the present invention is divided into two parts, a main body part and a plug part, and the power connector is connected so that these two parts are turned into a pair. The power connector is provided with a sliding groove formed thereon, and the plug portion is attached so as to be able to slide and rotate in the sliding groove. .

The slide grooves are formed with guide grooves on the left and right side surfaces orthogonal to the longitudinal direction thereof, and extend into the guide grooves on the left and right sides of the plug portion, and slide or rotate. More preferably, protrusions that can be formed are formed.

  In addition, it is possible to adopt that a switching means that functions when electricity is conducted through the plug portion in the main body portion. In this case, the main body portion has an upper side surface with a terminal hole which is further continuous with the front side surface on the opposite side of the lower side surface, and the conversion means includes a power supply circuit in which a transformer is incorporated. And a circuit board having an output terminal installed on the output side of the circuit board so that the free end of the circuit board is exposed from the terminal hole.

  On the other hand, on the upper side surface, the terminal hole is on the bottom surface, and the width of the electric product is connected to the output terminal protruding from the terminal hole from outside to receive the output of the conversion means. There are also those in which a holding groove is formed so that the electric product can be held on the bottom surface.

  In the power connector according to the present invention having the above configuration, when the plug portion is inserted into the power outlet, the plug portion is rotated according to the place of use by utilizing the sliding groove formed on the surface of the main body portion. In addition to being able to deform the whole power connector, the connecting part between the plug part and the main body part can be brought closer to the center of gravity position along the sliding groove, so that stress is applied to the plug part. Can be used to make the contact between the power outlet and the power outlet unsatisfactory, or the plug portion can be detached from the power outlet so that the entire power connector is dropped and broken.
