Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 , the power converter of the present invention includes a converter body 10 and a plug 20 . The converter main body 10 has a cylindrical housing 110 and a substantially cylindrical plug receiving body 120 installed in the upper portion of the housing 110 . The plug housing 120 has a cylindrical wall portion 121 and a cylindrical bottom portion 122 . The cylinder wall 121 is provided with two clamping grooves 123. The clamping grooves 123 have a guide groove 1231 opened downward from the upper end of the cylinder wall 121 and a lower part of the guide groove 1231 and a circumference along the circumference of the cylinder wall 121. The rotation slot 1232 extending in the direction. An anti-rotation recess 124 is defined on the bottom 122 of the plug receiving body 120 . Two main body terminals 130 are fixed on the plug receiving body 120. The main body terminal 130 has a connecting portion 131 and an arc-shaped elastic guiding arm 132 bent and extended from the connecting portion 131. The elastic guiding arm 132 extends into the plug receiving body Within 120.

Please refer to FIG. 1 , FIG. 2 and FIG. 3 , the plug 20 includes a plug socket 210 , two shrapnel terminals 220 , a plug shell 240 and a plug terminal set 250 . The plug shell 240 is fixed on the plug socket 210 , and the plug terminal set 250 is pivotally mounted between the plug shell 240 and the plug socket 210 .

The plug base 210 defines two terminal grooves 211 on the upper surface. The lower part of the plug base 210 has a substantially cylindrical body part 212 . The plug base 210 is provided with an anti-rotation hole 215 passing through the upper and lower surfaces of the plug base 210 . Two arc-shaped guide slots 213 are defined on the barrel portion 212 , and a connecting slot 214 is defined on the side wall of the guide slot 213 , and the connecting slot 214 communicates with the shrapnel terminal slot 211 and the guide slot 213 . Two clamping feet 216 protrude outward from the lower portion of the barrel portion 212 .

The spring terminal 220 has a pressing piece 221 , and one end of the plug terminal set 250 can be pressed against the pressing piece 221 . An arc-shaped elastic portion 222 is extended from one end of the pressing piece 221, and a substrate 223 overlapping with the pressing piece 221 is extended from the end of the elastic portion 222. The end of the substrate 223 is bent downward to extend a lead piece 224 , and the guiding piece 224 is located in the elastic piece terminal slot 211 .

The plug base 210 is provided with a limiting terminal 231 and a conical helical spring 232 in the anti-rotation hole 215. One end of the limiting terminal 231 forms a roughly hemispherical locking part 2311, and the other end of the limiting terminal 231 is opened. There is a groove (not shown in the figure), and the smaller end of the spring 232 extends into the groove of the limiting terminal 231 and abuts against the groove wall, and the larger end of the spring 232 abuts against the on the plug housing 240.

When the plug 20 is docked with the main body 10 of the converter, the clamping feet 216 should first be extended into the guide groove 1231.
