Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2 below, the plastic power key includes a power key main body 5, the power key main body 5 includes a fixing member 2, a contact member 1 and a metal contact piece 3, the contact member 1 and the fixing member 2 are mutually matched, a contact post 8 and a contact head 7 are arranged inside the fixing member 2, a pressing block 6 is arranged at the bottom of the contact member 1, the pressing block 6 is fixedly connected with the contact member 1, the pressing block 6 penetrates through the fixing member 2, the contact post 8 and the contact head 7 are both of an integrally formed structure, the pressing block 6 is in contact fit with the contact head 7, the contact post 8 is connected with the metal contact piece 3, a fixing support leg 4 is arranged at the bottom of the fixing member 2, the length of the fixing support leg 4 is slightly greater than that of the metal contact piece 3, and the fixing member 2, the contact member 1, the metal contact piece 3, The fixed support legs 4 are made of plastics, the manufacturing cost is low, the raw material sources are wide, large-scale production can be achieved, and the metal contact piece 3, the pressing block 6, the contact column 8 and the contact head 7 are made of conductive materials.

Example 1: as shown in fig. 2, when in use, the contact 1 and the pressing block 6 are pressed to press the contact post 8 and the contact head 7 in the fixture 2, and further to press the metal contact piece 3, thereby achieving the purpose of pressing the switch element.

Example 2: as shown in fig. 3, the present embodiment is different from embodiment 1 in that a metal elastic sheet 9 is additionally disposed at the bottom of the contact post 8 and the contact head 7, the pressing effect can be better by disposing the metal elastic sheet 9, it can be avoided that the contact post 8 and the contact head 7 are suddenly stuck when pressing the metal contact piece 3, and the original shape cannot be recovered, when in use, the pressing block 6 is further pressed by pressing the contact piece 1, the contact post 8 and the contact head 7 inside the fixing piece 2 are pressed, and then the metal elastic sheet 9 is pressed, and the metal elastic sheet 9 presses the metal contact piece 3, so as to achieve the purpose of pressing the switch element.
