Embodiment

Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.

As depicted in figs. 1 and 2, the VDE three-electrode power plug that the utlity model has grounding elastic part comprises:

Internal frame 1:

Be equipped with two

terminals

11,12 on the internal frame 1, with before two terminals, 11,12 grafting directions are defined as, after two terminals, 11,12 riveting line directions are defined as, that is: before the downward direction of arrow A indication is among Fig. 1 and Fig. 2, after the direction that makes progress of arrow B indication is, wherein, the terminal grafting is known in those skilled in the art with the direction of riveting line; In the edge of internal frame 1, towards rear side, outstanding respectively first built-in brick 13 and second built-in brick 14 of being provided with; The outward flange of first built-in brick 13 and second built-in brick 14 is near the back-end location place, outstanding respectively first confinement block 15 and second confinement block 16 of being provided with, as shown in Figure 3, be respectively arranged with shrinkage pool 151,161 on first confinement block 15 and second confinement block 16, and the notch of shrinkage pool 151,161 is towards the front side.

Grounding elastic part 2:

Be bent into the bow shape by sheet metal, its two ends that are close are set at

first section portion

21 and 22, the first sections portions 21 of second section portion and second section portion 22 respectively and rabbet outward flange at first built-in brick 13 and second built-in brick 14 respectively; The end of first section portion 21 and second section portion 22 inserts shrinkage pool 151,161 respectively.

Insert shrinkage pool 151,161 by the first section portion 21 of grounding elastic part 2 and the end of second section portion 22, can select mechanical system so that grounding elastic part 2 forms with internal frame 1 firmly to be combined easily, or manpower, all can finish assembling easily.And then via the plastics ejection formation, thereby formation VDE three-electrode power plug 5 as shown in Figure 4.Because first section portion 21 of grounding elastic part 2 and second section portion's 22 end can insert the shrinkage pool 151,161 of first confinement block 15 and second confinement block 16 respectively, therefore the end of first section portion 21 of grounding elastic part 2 and second section portion 22 is subjected to the restriction of first confinement block 15 and second confinement block 16 respectively, and can be not naked not going out the rear end of first built-in brick 13 and second built-in brick 14, grounding elastic part 2 can be saved material relatively and save equipment energy consumption thus.

As shown in Figure 5 and Figure 6, show further embodiment of the utility model from two angles respectively, wherein first built-in brick 13 and second built-in brick 14, its outward flange central authorities are formed with protuberance 152 respectively, 153, and protuberance 152, each forms groove 152A relatively 153 both sides, 152B and 153A, 153B,

groove

152A, 152B and 153A, 153B is forming cell wall 152C respectively towards the front position place, 152D and 153C, 153D, and first section portion 21 and second section portion 22 of grounding elastic part 2 form two flank sheet 21A respectively, 21B and 22A, 22B,

fin

21A, 21B and 22A, 22B respectively with

cell wall

152C, 152D and 153C, 153D conflicts.Therefore, after first section portion 21 of grounding elastic part 2 and second section portion's 22 end insert the shrinkage pool 151,161 of first confinement block 15 and second confinement block 16 respectively,

fin

21A, 21B and 22A, 22B conflict with

cell wall

152C, 152D and 153C, 153D respectively, thereby it is afterwards more firm to make that the end of first section portion 21 and second section portion 22 of grounding elastic part 2 inserts the shrinkage pool 151,161 of first confinement block 15 and second confinement block 16 respectively.If remove or dismounting grounding elastic part 2,

fin

21A, 21B and 22A, 22B are broken away from respectively and each

cell wall

152C, 152D and the inconsistent state of 153C, 153D, make the first section portion 21 of grounding elastic part 2 and the end of second section portion 22 can withdraw from the shrinkage pool 151,161 of first confinement block 15 and second confinement block 16 respectively then, thereby realize dismounting.

As can be seen from the above embodiments, first section portion 21 and the second section portion 22 ends shrinkage pool 151,161 that can respectively insert first confinement block 15 and second confinement block 16 of the utility model embodiment by grounding elastic part 2, therefore the end of first section portion 21 of grounding elastic part 2 and second section portion 22 is subjected to the restriction of first confinement block 15 and second confinement block 16 respectively, and can be not naked not going out the rear end of first built-in brick 13 and second built-in brick 14, grounding elastic part 2 can be saved material relatively and save equipment energy consumption thus.

The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection range of the present utility model.
