Example 1:

the power adapter with the elastic insertion sheet shown in fig. 1-2 comprises a box body 1, a supporting block 2 fixed at the front end of the box body 1, and two groups of insertion sheets 3 fixed outside the supporting block 2, wherein the insertion sheets 3 are divided into an exposed section 31 and a non-exposed section 32, the exposed section 31 is divided into a fixing sheet 311, a pressure spring 312 vertically installed at two side surfaces of the middle part of the fixing sheet 311, and a bending sheet 313 connected with the pressure spring 312; the width of the fixing piece 311 is 0.8mm to 1mm shorter than the width of the insertion hole of the socket (not shown), wherein two ends of the bending piece 313 are welded to the fixing piece 311, the middle part of the bending piece 313 is a bending part 3131, the bending part 3131 can be bent towards the direction close to the fixing piece 311, the bending piece 313 is in an isosceles triangle shape without being affected by external force, the bending part 3131 is connected with the pressure spring 312, the thickness of the bending piece 3131 is 0.5 mm to 0.8mm, and the length of the pressure spring 312 in a natural state is 2 mm to 4 mm; the outer side surface of the box body 1 is also provided with anti-skid concave surfaces 11 which are arranged in parallel; two groups of pressure springs 312 are arranged on the left side surface and the right side surface of the fixing piece 311; the non-exposed section 32 is used for cable connection to a circuit board (not shown) in the case 1.

It should be further explained that the working principle of the insertion sheet 3 of the present invention is that when the insertion sheet 3 is engaged with the socket, the bending portion 3131 of the bending sheet 313 moves to the side close to the fixing sheet 311 and compresses the compression spring 312, and the bending sheet 313 abuts against the side of the slot of the socket due to the reaction force of the compression spring 312 when the insertion sheet 3 is engaged with the socket.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
