Description

Power adapter with reversible plug direction

technical field

The invention relates to a power converter, in particular to a power converter capable of changing the direction of a plug.

Background technique

With the advancement of science and technology, various electrical appliances (such as mobile phones, computers, televisions, etc.) Get a power source.

A power converter in the prior art, its main structure is that two plug blades protrude from a body, and a conversion element electrically connected to the two plug blades is arranged inside the body. When in use, the two plug blades are used to Insert the piece into the jack of the socket, so that the power is input into the body through the plug piece, and the input power is transformed and rectified by the conversion element, and then converted into a power supply suitable for electrical appliances.

However, since the body of the power converter is equipped with conversion elements, the power converter has a relatively large volume, and the direction of the two plug blades relative to the body is fixed and unchangeable, so when the power converter is inserted into the power converter with its plug blades When a group of jacks on the socket is connected, the body of the power converter often blocks the remaining unused jacks on the socket, so that the unused jacks cannot effectively provide plug blades of plugs of other electrical appliances for insertion.

In order to prevent the power converter from being inconvenient to use due to its large size, please refer to FIG. The plug 50 that rotates relative to the body 40 is used to adjust the body 40 to have a better use position relative to the plug 50, so that when the plug blade 51 of the plug 50 of the power converter is inserted into a group of jacks on the socket 60, the body 40 will cover the remaining unused jacks; however, both the body 40 and the plug 50 have a considerable volume, so when the plug 50 of the power converter is inserted into the vertically arranged socket 60, the body 40 and the plug 50 will be opposite to the plug 50.

The outer sides of 12 are in contact with each other, and the bottom end of the conductive rod 12 protrudes from the bottom surface of the conductive sheet 13, and a shrapnel 14 is formed at the bottom of the body 10 adjacent to the assembly seat 11. The end of the shrapnel 14 facing the assembly seat 11 is a free end, and the A block 141 protrudes downward from the free end;

The plug 20 has a base 21, two plug blades 22, two contact blades 23 and a cover 24. The base 21 is provided with two insertion holes 211 at intervals. The inner surface of the base 21 facing the cover 22 is adjacent to The two insertion holes 211 are respectively provided with a boss 212; the tops of the two plug pieces 22 are respectively connected with a contact piece 23, and one side of each contact piece 23 is bent upward to form a protruding piece 231, and on each contact piece 23 There is a through hole 232 through which the two plug blades 22 pass through the two insertion holes 211 from the inner surface of the base 21, so that the bottom ends of the plug blades 22 protrude from the outer surface of the base 21, and the contact piece 23 is held against the inner surface of the base 21. And the perforation 232 of the contact piece 23 accommodates the corresponding boss 212 of the base 21, so that the plug piece 22 is positioned on the base 21; the cover 24 is concavely provided with a mounting groove 241 on the outer surface away from the base 21, The installation groove 241 is X-shaped in accordance with the shape of the assembly seat 11. The center of the installation groove 241 is a circular groove 242. The groove surface of the circular groove 242 is concavely provided with a ring groove 243. There are four circular grooves 242 at intervals. Radial extension grooves 244, a gap 245 is formed on one side of each extension groove 244, and the cover body 24 is covered on the base 21; the plug 20 is correspondingly accommodated with a body 10 of the assembly seat 11, so that the four extensions 112 of the assembly seat 11 are positioned inside the plug 20 through the corresponding gaps 245, and the two conductive pieces 13 arranged on the extensions 112 are respectively connected to the protruding pieces 231 of a contact piece 23. In addition, the bottom end of the conductive rod 12 is located in the ring groove 243 , and the locking block 141 of the elastic piece 14 is engaged in one of the extension grooves 244 .

Please refer to FIG. 4 , when the plug 20 is actually combined with the body 10 in the actual operation, the mounting groove 241 of the cover 24 of the plug 20 is firstly accommodated with the assembly seat 11 of the body 10 so that the assembly seat 11 The disc body 111 is located in the circular groove 242 of the installation groove 241, and the four extensions 112 of the assembly seat 11 are respectively located in the corresponding extension grooves 244. At this time, the block 141 of the elastic piece 14 is pressed against by the top surface of the cover body 24. Please refer to Figures 5 and 6 for further cooperation. Rotate the plug 20 relative to the main body 10 at an angle, so that the conductive rod 12 slides along the ring groove 243, and the four extensions 112 of the assembly seat 11 respectively pass through the corresponding gaps 245. And located below the cover 24, the block 141 of the elastic piece 14 snaps into one of the extension grooves 244, so that the plug 20 cannot be rotated relative to the main body 10 to obtain positioning, and the protruding pieces 231 of the two contact pieces 23 are respectively arranged on the extension part. One side of the bottom surface of the two conductive sheets 13 on 112 is in contact with each other, so the power obtained by inserting the plug sheet 22 into the jack of the socket can be transmitted to the conductive sheet 13 through the contact sheet 23, and then input to the body through the conductive rod 12 The conversion element inside 10 transforms the input power and rectifies it into an appropriate power supply through the conversion element, and uses it as a power supply; and presses the shrapnel 14 to disengage the clamping block 141 of the shrapnel 14 from the extension groove 244, and At the same time, reversely rotate the plug 20 relative to the body 10 so that the four extensions 112 of the mounting base 11 are located in the extension slots 244 through the corresponding notches 245 , and the plug 20 and the body 10 can be separated from each other.
