Description

power converter

technical field

The utility model relates to a power converter, in particular to a power converter with a replaceable plug.

Background technique

Electronic products generally require power converters to charge or power them. In order to increase the applicability of the power converter, a replaceable plug is often used. A power converter using a replaceable plug generally includes a converter main body and a plug. One way of fixing the plug of the power converter and the main body of the converter is that the main body of the converter has an elastic pressing hook plate, the end of the hook plate has a hook body, and the plug has a button hole, and the plug passes through The hook body on the hook plate is hooked in the button hole to realize the fixation with the main body of the converter; press the hook plate to make the hook body disengage from the button hole, and then the plug can be taken out. Chinese Patent No. 200520127782.1 published on January 3, 2007 discloses another way of fixing the plug of the power converter and the main body of the converter. The main body of the converter has an elastic pressing member and the plug is provided with grooves The plug is held in the groove by the pressing piece to be fixed with the main body of the converter. The plug can be taken out by pressing the pressing part to disengage from the groove.

However, the above two power converters need to press the hook plate or the pressing part to take out the plug, which is troublesome to use; if you forget to press the hook plate or pressing part, it is easy to cause damage to the power converter.

Utility model content

The purpose of this utility model is to provide a power converter that is easy to use and not easy to damage, aiming at the shortcomings of the above-mentioned prior art.

To achieve the above purpose, the power converter provided by the utility model includes a converter main body and a plug, the converter main body includes a plug receiving body, the plug includes a plug socket, the plug receiving body has a holding bar, the The clamping strip has a sliding surface and a clamping surface; the lower part of the socket has a retaining block, which includes a sliding contact surface and a clamping surface that can withstand the clamping strip and can be pushed and clamped The surface thus presses down the retaining slope of the clamping bar.

As mentioned above, when the plug of the present utility model is assembled on the main body of the converter, by virtue of the elasticity of the clamping strip, the sliding contact surface slides over the sliding surface, and the clamping surface automatically resists the inclined surface so that the plug and the main body of the converter are clamped. fixed together; apply a reverse force to the plug, and the retaining slope will rely on the decomposition of the force on the inclined surface to generate a squeeze component force on the end of the clamping strip corresponding to the clamping surface, thereby pressing down the clamping strip. The plug is easily removed. In a word, the power converter is easy to use and not easy to be damaged by misuse.

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 includes a cylindrical housing 110, a substantially cylindrical plug receiving body 120 mounted on the housing 110, and two cylindrical body terminals fixed on the plug receiving body 120. 130.

Referring to FIG. 2 , the plug receiving body 120 has a bottom 121 and a wall 125 vertically extending from the bottom 121 . The cylinder wall 125 is provided with two clamping grooves 124. The clamping groove 124 has a guide groove 1241 opened downward from the upper end of the cylinder wall 125 and a guide groove 1241 connected with the lower part of the cylinder wall 125 and extending along the cylinder wall 125. The rotating groove 1242 extending in the circumferential direction. There is a ring-shaped groove 122 on the bottom 121 of the cylinder. A clamping strip 123 extends from the edge of one end of the groove 122 at the bottom of the cylinder 121. A part of the clamping strip 123 protrudes from the groove 122. The clamping strip 123 has a The sliding surface 1231 and a clamping surface 1232 .

Please refer to FIG. 1 , FIG. 3 , FIG. 4 and FIG. 5 , the plug 20 includes a plug socket 210 , two spring 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 lower part of the plug socket 210 has a base 211 . A substantially triangular retaining block 212 protrudes from the lower surface of the seat bottom 211. The retaining block 212 has an arc-shaped sliding contact surface 2121 and a substantially inclined plane connected to the sliding contact surface 2121. Block the slope 2122. Two shrapnel terminal grooves 213 are opened on the plug base 210. The shrapnel terminal groove 213 has a fan-shaped annular groove 2131 and a fan-shaped annular groove opened from the bottom wall of the horizontal groove 2131 and passing through the plug holder 210. Main body terminal slot 2132 . A fixing post 214 protrudes from one end of the socket 210 close to the terminal groove 213 of the elastic piece. The lower portion of the plug socket 210 has two protruding legs 215 .

The spring terminal 220 has a ring-shaped pressing piece 221 that can abut against the plug terminal set 250 . One end of the resisting piece 221 defines a fixing hole 225 , and the fixing hole 225 is sleeved on the fixing column 214 . The other end of the resisting piece 221 is bent to extend an arc-shaped elastic connecting portion 222 . An annular resisting piece 223 extends from the end of the elastic connecting portion 222 . The end of the resisting piece 223 is bent to extend an elastic supporting portion 224 . The end of the elastic supporting portion 224 abuts against the resisting piece 221 .
