New description: [New technical field] This creation relates to a power converter, in particular 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. Chinese Patent No. 200520127782.1, issued Jan. 3, 2007, discloses a power converter comprising a converter body and a replaceable plug having a push-type latching mechanism on the body of the converter. When the plug is assembled to the main body of the converter, the holding mechanism automatically fixes the plug; when the plug is removed, the plug can be removed after pressing the holding mechanism. However, the above-mentioned power converter has to press the latching mechanism to remove the plug, which is cumbersome and inconvenient to use, and if the driver forgets to press the latching mechanism, pulling out the plug often damages the latching mechanism. [New Content] The purpose of this creation is to provide a power converter that is easy to use and not easily damaged in view of 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 having a plug receiving body, the plug receiving body has an anti-rotation recess; and a plug having a plug An anti-rotation hole is defined in the plug socket, and a anti-rotation hole is provided with a spring and a limit terminal which can extend into the anti-rotation recess at one end, and one end of the spring is pressed.

The upper group wears the day # Ϊ, paste the electricity _ changer to the converter main body under the automatic assembly into position after the limit terminal - the end will be on the role of the spring. For the cup, to prevent the concave and convex (four), so that the insertion position is reversed on the side wall of the converter body, and the limit terminal will be finely returned under the anti-rotation recesses, so that it can be conveniently taken from the converter body. Take out the insertion and damage = and the power converter of this creation makes the money, and it is not easy to operate by mistake. [Embodiment] To explain in detail the technical content, structural features, achieved goals, and effects of the creation, the following examples are given in conjunction with the drawings. Explain. Referring to the first figure, the author of the power converter includes a = and a plug 20. The main body 1G of the conversion 11 has a cylindrical shape; a housing and a plug body 120 which is mounted on the upper portion of the housing 11G and has a substantially cylindrical shape. The plug housing 120 has a tubular wall portion 121 and a tubular bottom wall portion U1. Two latching slots 123 are defined. The latching slot 123 has a bow guide 1231 extending downward from the upper end of the tubular wall portion 121 and a rotary groove 1232 that communicates with the lower portion of the guide groove 1231 and extends in the circumferential direction of the cylinder wall "21. An anti-rotation recess 124 is defined in the bottom portion ι22 of the plug housing 120. Two main body terminals 13A are fixed on the plug receiving body 120, and the main body terminal (10) has an arc-shaped elastic guiding arm 132 which is bent and extended by the connecting portion 131, and the elastic guiding arm 132 extends into the plug. The inside of the container is 12 inches. - 6 M339820 Referring to the first, second and third figures, the plug 20 includes a plug socket 210, two spring tab terminals 220, a plug housing 240 and a plug terminal set 250. The plug housing 240 is fixed to the plug housing 21 , and the plug terminal set 250 is pivotally mounted between the plug housing 240 and the plug housing 21 . The plug housing 210 is provided with two spring terminal slots 211 at the upper surface. The lower portion of the connector housing 210 has a substantially cylindrical tubular portion 212. The plug base 210 has an anti-rotation hole 215 extending through the upper and lower surfaces of the plug housing 210. Two arcuate introduction slots 213 are defined in the tubular portion 212. A connecting slot 214 is defined in the sidewall of the introduction slot 213. The connecting slot 214 communicates with the spring terminal slot 211 and the introduction slot 213. Two legs 216 are outwardly projected from the lower portion of the barrel portion 212. The shrapnel terminal 220 has a pressing piece 221 , and one end of the plug terminal set 250 can abut against the pressing piece 221 . One end of the pressing piece 221 extends from an arc-shaped elastic portion 222, and a distal end of the elastic portion 222 extends a substrate 223 which is overlapped with the pressing piece 221, and the end of the substrate 223 is bent downward to extend a guiding end. The sheet 224 and the guide piece 224 are located in the spring terminal groove 211. A limiting terminal 231 and a conical spiral spring 232 are disposed in the anti-rotation hole 215. One end of the limiting terminal 231 forms a substantially hemispherical card abutting portion 2311, and the other end of the limiting terminal 231 A recess (not shown) is formed. The smaller diameter end of the spring 232 extends into the recess of the limiting terminal 231 and abuts against the slot wall. The larger diameter end of the spring 232 abuts. On the plug housing 240. When the plug 20 is docked with the converter body 10, the pin 216 M339820 should first be inserted into the guiding slot. At this time, the elastic guiding arm 132 falls into the guiding slot 213; then the plug 2 旋转 is rotated to make the elastic guides A part of 32 is inserted into the elastic piece terminal slot 211 via the connecting groove 214, and the elastic guiding contact points 224 abut against each other to achieve electrical conduction; at this time, the card of the limiting terminal 231 is elasticized by the elastic sauce. The abutting portion 2311 is inserted into the anti-rotation recess 124, so that the plug 20 is fixed to the converter main body 10. When the plug 2 is removed from the converter body 10, a reverse force is applied to the plug 2G, and the latching portion is retracted by the side wall of the anti-rotation recess 124, so that the plug 2q can be rotated back relative to the converter body 10 and Remove the plug 2〇. As described above, when the plug 2 of the present power converter is assembled to the converter body ί, when assembled, the end of the limit terminal 231 is automatically clamped to the anti-rotation recess 124 by the action of the spring 232. Thereby, the plug 20 is positioned on the converter body H). A reverse force is applied to the plug 2 (), and the limit terminal 23i X is retracted under the action of the side wall of the anti-rotation recess 124, so that the plug 2G can be conveniently taken out from the converter main body 10, thereby converting the power source. The device is easy to use and is not easily damaged by misoperation. [Simple diagram of the diagram] The first diagram is a perspective view of the converter body and the plug separated from the author of the power converter. The second figure is a perspective view of the plug socket, the spring terminal and the spring portion of the plug of the power converter shown in the first figure. The third figure is an exploded perspective view of the plug socket, the shrapnel terminal, the limit terminal and the spring portion of the plug shown in the second figure. 8 M339820 [Key component symbol description]
