New description: [New technical field] The present invention relates to a power converter, and more particularly to a power converter with a replaceable plug. [Prior Art] Press, electronic products generally require a power converter to charge or supply power. Power converters often use interchangeable plugs for added applicability. The current pluggable power converter generally includes a rectangular converter body and a smaller plug that is assembled from a larger surface of the converter body to the converter body; power conversion of such a replaceable plug The device is easy to manufacture. Such a power converter is disclosed in U.S. Patent No. 6,669,495, issued December 30, 2003, and U.S. Patent No. 6,923,667, issued to Aug. However, when the rectangular converter body of the power converter is used on a multi-jack socket, the occupied area in the horizontal direction is large, and the adjacent jack is unusable, which causes inconvenience in use; The above-mentioned power converter generally needs to take out the plug from the main body of the converter when carrying, otherwise it is easy to scratch other items and is not easy to carry. [New Content] The purpose of this creation is to provide a power converter that is easy to use and carry with regard to the above-mentioned deficiencies of the prior art. In order to achieve the above object, the power converter provided by the present invention comprises a converter body and a plug; wherein the converter body further comprises: a circular M339839 cylindrical housing; a plug receiving body mounted at one end of the housing, The plug receiving body has a tubular wall portion, and the tubular wall portion is provided with two or more locking card slots; the plug further comprises: a plug seat, the lower portion of which protrudes outwardly with more than two latching legs; the latching legs can receive In the card foot card slot. As described above, the plug of the present power converter is assembled from the end of the cylindrical converter main body to the converter main body, and when used in a multi-jack discharge socket, the area occupied in the horizontal direction can be reduced. It can avoid the situation that other jacks of the row socket can not be used, which can bring convenience to the user. In addition, since the plug is inserted into one end of the main body of the converter, it is easy to realize the integrated shape of the two, so that it can be easily carried. [Embodiment] In order to explain in detail the technical contents, structural features, objectives and effects of the present invention, the following is a detailed description with reference to the drawings. Referring to the first figure, the present power converter includes a converter body 10 and a plug 20. The converter body 10 includes a housing 110, a plug receptacle 120, two body terminals 130, and two latching tabs 140. The main body terminal 130 is fixed to the plug receiving body 120. The main body terminal 130 has a cylindrical terminal body 131. The upper end of the terminal body 131 extends laterally with an abutting portion 132. Referring to the first, second, third and fourth figures, the housing 110 is substantially cylindrical, and has an annular upper ill at the upper portion of the inner wall and an inner wall of the upper surface of the bracket m. A receiving body limiting block 112 is protruded. The plug housing 120 is mounted on the upper portion of the housing 110 and has a substantially circular M339839 cylindrical shape. The plug housing 12G has a cylindrical wall portion 121 and a cylindrical bottom portion i22. The cylinder wall=121 is provided with two latching slots 123. The latching slot 123 is formed by a guiding slot 1231 extending downward from the upper end surface of the cylinder wall 121 and an arc-shaped rotation communicating with the guiding slot 1231. The slot 1232 is formed. Two elastic grooves 124 are also formed in the tubular wall portion i2i. The elastic groove 124 penetrates into the tubular bottom 122 and an inward opening 1241 is formed in the tubular wall portion 121. The outer surface of the tubular wall portion 121 has a limiting slot 125, and the receiving body limiting block 112 is retained in the limiting slot 125. The holding elastic piece 140 is held in the elastic piece groove 124, and the holding elastic piece 140 has a snap-shaped engaging portion 141, and the holding portion 141 protrudes from the opening 1241 to the cylindrical wall portion 121. A retaining piece 142 is defined on each of the two sides of the retaining portion 141. The lower edge of the retaining piece 142 is bent outwardly to extend a retaining leg 143. The retaining leg 143 is clamped between the base 122 and the bracket ill. Referring to the fifth and sixth figures, the plug 20 includes a plug socket 210, two spring tab terminals 220, a plug terminal set 230 and a plug housing 240. The plug terminal set 230 is pivotally mounted between the header 210 and the plug housing 240. The plug housing 210 has a disk body 211 having a substantially disk shape. The bottom of the disk body 211 is provided with two spring terminal slots 212. The spring terminal slot 212 includes a slot portion 2121 and a side slot portion 2122 extending through the bottom of the disk body 211. The bottom of the disk body 211 is upwardly convex with two cylindrical elastic piece limiting posts 213. The lower surface of the bottom of the disk body 211 projects downwardly from a substantially cylindrical tubular portion 214 and two grooved wall portions 216 which are curved in the tubular portion 214. The groove wall portion 216 and the cylindrical portion 214 enclose two main body terminal grooves 217, and the main body terminal grooves 217 7 M339839 communicate with the side groove portions 2122. The cylinder portion 214 is provided with two card slots 2141 and two guiding grooves 2142 which are gradually shallower in the circumferential direction. The card slot 2141 and the guiding slot 2142 are divided into two groups, and the tail end of the guiding slot 2142 is close to the card slot of the same group. 2141. A terminal holding portion 2143 extends in a lower portion of the tubular portion 214 into the main body terminal groove 217. Two legs 215 are protruded outwardly from the lower portion of the barrel portion 214. The elastic piece terminal 220 has a spring piece portion 221, and the elastic piece portion 221 is received in the groove portion 2121, and the plug terminal group 230 is movably abutted against the elastic piece portion 221. A limiting hole 222 is defined in the elastic portion 221, and the limiting hole 222 is sleeved on the elastic limiting column 213. One side edge of the elastic piece portion 221 is extended and bent to form an elastic contact portion 223, and the elastic contact portion 223 is located in the main body terminal groove 217. A plug housing 24 is fixed to the connector housing 210. The plug housing 24 defines a plug terminal hole 241 and a plug terminal receiving slot 242 communicating with the plug terminal hole 241. The plug terminal group 23 is rotatable so that the portion exposed outside the plug housing 24 is received in the plug terminal receiving groove 242 Θ; thereby making the power converter more convenient to carry. When the plug 20 is assembled to the main body 1 of the converter, the leg 215 is first placed in the guide groove 1231; at this time, the abutting portion I32 enters the main body terminal groove 217, and the engaging portion 141 enters the guide groove 2142. Then, the plug 20 is rotated by a certain angle with respect to the converter main body 10 until the catching portion H1 enters the card slot 2U1 from the guide groove 2142 / month. At this time, the leg 21s slides into the rotating slot, and the plug 2〇 reaches the conversion body 1G. Fixed; the abutting portion 132 slides over the terminal retaining portion and abuts against the shaft (four) portion 223 to achieve a new connection. When the 8 M339839 plug 20 is taken out from the converter main body 10, a reverse force is applied to the plug 20, and the latching portion 141 is retracted by the side wall of the card slot 2141, and the leg 215 is returned to the guiding slot 1231. At this point, the abutting portion 132 returns to the main body terminal groove 217, so that the plug 20 can be taken out. As described above, the plug of the present power converter is docked and assembled with one end of the cylindrical converter body 10, and when used on a multi-jack row socket, the area occupied in the horizontal direction can be reduced, and can be avoided. The Socket's _ its jack can not be used, which can be convenient for use. In addition, since the plug 20 is inserted into one end of the converter main body 10, it is easy to realize the integrated design of the two, so that it can be easily carried.
