DETAILED DESCRIPTION

[0024] The utility model will be further described below in combination with the drawings.

[0025] As Figures 1 to 5 shown, a kind of flat-shaped conversion plug, it includes connecting shell 10 and flat-shaped plug-in sheet 20, the inside movable mounting of connecting shell 10 has flat spring structure 30, part of flat-shaped plug-in sheet 20 is located in the inside of flat spring structure 30, flat spring structure 30 is used to the clamping and fixing of flat-shaped plug-in sheet 20 quickly, so that flat-shaped plug-in sheet 20 is conveniently operated dynamically, flat spring structure 30 includes the connecting sheet 31 of shape as transverse U, the both ends of connecting sheet 31 are connected with V-shaped spring sheet 32, two V-shaped spring sheets 32 are symmetrically arranged about connecting sheet 31, and the end of each V-shaped spring sheet 32 is fixedly connected with connecting structure, connecting structure is connected with connecting shell 10, and connecting structure is used to fix V-shaped spring sheet 32 and connecting sheet 31 in the inside of connecting shell 10.

[0026] When flat-shaped plug-in sheet 20 is not inserted into the inside of connecting shell 10, the minimum spacing between two V-shaped spring sheets 32 is less than the thickness of flat-shaped plug-in sheet 20, in the process of inserting flat-shaped plug-in sheet 20 into the inside of connecting shell 10, flat-shaped plug-in sheet 20 will enter between two V-shaped spring sheets 32, and with the movement of flat-shaped plug-in sheet 20, two V-shaped spring sheets 32 will be elastically deformed relatively, so that the end of flat-shaped plug-in sheet 20 is attached to connecting sheet 31, at this moment, flat-shaped plug-in sheet 20 will be clamped under the reaction force of V-shaped spring sheet 32, to complete the fixing operation of flat-shaped plug-in sheet 20, so that the operation of installing flat-shaped plug-in sheet 20 is more simple, and flat-shaped plug-in sheet 20 is conveniently removed, V-shaped spring sheet 32 can be clamped and fixed to flat-shaped plug-in sheet 20 of more thickness, and V-shaped spring sheet 32 can buffer flat-shaped plug-in sheet 20, greatly avoid the situation that flat-shaped plug-in sheet 20 is loose or contact is poor due to vibration.

[0027] It should be noted that the width of the flat tab 20 is less than the width of the connecting piece 31, so that the angle of the flat tab 20 can be fine-tuned, so that the flat tab 20 can be better connected with the external interface, and the length of the connecting piece 31 is adapted to the length of the internal size of the connecting shell 10, and the thickness of the connecting piece 31 is adapted to the thickness of the internal size of the connecting shell 10, so that there is no positional deviation after the connecting piece 31 is placed inside the connecting shell 10.

[0028] As Figure 1 And Figure 3 , the connecting structure includes a fixed piece 33 connected with the V-shaped spring piece 32, and at least one connecting lug 34 is fixedly connected to one side of the fixed piece 33 close to the connecting shell 10. At least one connecting slot 101 is formed in the two opposite sides of the connecting shell 10, and the connecting lug 34 is inserted into the inside of the connecting slot 101, and the connecting lug 34 corresponds to the connecting slot 101 one by one.

[0029] When the flat spring structure 30 needs to be connected with the flat tab 20, press the two fixed pieces 33 to make the two fixed pieces 33 close to each other, at this time the V-shaped spring piece 32 will be deformed, then the connecting piece 31, the V-shaped spring piece 32 and the fixed piece 33 are placed inside the connecting shell 10 and the fixed piece 33 is moved, when the connecting lug 34 corresponds to the position of the connecting slot 101, the connecting lug 34 is inserted into the inside of the connecting slot 101 under the action of the V-shaped spring piece 32, thereby completing the fixing operation of the flat spring structure 30, at this time the V-shaped spring piece 32 and the connecting piece 31 are stably installed inside the connecting shell 10, making the operation of disassembling the flat spring structure 30 more convenient, when a part of the flat spring structure 30 is damaged, it is convenient for replacement operation.

[0030] As Figure 3 , a plurality of heat dissipation grooves one 311 are formed on one side of the connecting piece 31, and a plurality of heat dissipation grooves two 321 are formed on one side of each V-shaped spring piece 32.

[0031] The heat dissipation grooves one 311 and the heat dissipation grooves two 321 can perform heat dissipation operation on the position of the flat tab 20 between the flat spring structure 30, thereby greatly avoiding the heat generated by the flat tab 20 during work from being accumulated inside the flat spring structure 30.

[0032] As Figure 1 And Figure 4 , the connecting shell 10 is provided with a communication cavity 102 on one side, and the two sides adjacent to the communication cavity 102 are provided with a heat dissipation channel 103, and the communication cavity 102 and the heat dissipation channel 103 are communicated with the inside of the connecting shell 10.

[0033] The heat inside the connecting shell 10 can be dissipated to the outside through the communication cavity 102 and the heat dissipation channel 103, avoiding the situation that the temperature inside the connecting shell 10 is high.

[0034] As Figure 4 The end of the connecting shell 10 is connected with the plug 11, and the reinforcing rib plate 12 is connected between the plug 11 and the connecting shell 10, which is used to increase the connection stability between the plug 11 and the connecting shell 10.

[0035] The bending part of the V-shaped spring sheet 32 has a transition fillet, which can not only improve the structural strength of the V-shaped spring sheet 32, but also increase the elastic performance of the V-shaped spring sheet 32, so that the V-shaped spring sheet 32 is more smooth when deformed. The end of the flat insert sheet 20 is provided with a transition inclined surface 21, which can make the flat insert sheet 20 more smoothly enter between the two V-shaped spring sheets 32, and avoid the situation that the flat insert sheet 20 is scratched when inserted between the two V-shaped spring sheets 32.
