Therefore, the pressing piece 1 can be pressed conveniently, meanwhile, pressing force can be concentrated and applied to a smaller area of the elastic wrapping portion 22, the elastic wrapping portion 22 can be pressed and deformed when the pressing piece 1 is pressed by applying smaller force, the switch key on the flexible circuit board 3 can be pressed easily to realize a key function, and pressing hand feeling of the key 10 is improved.

Wherein, when the pressing portion 11 is accommodated in the pressing key groove 201, the pressing surface of the pressing portion 11 may protrude from the outer surface of the terminal 100, so that the pressing portion 11 can be easily pressed.

In addition, as shown in fig. 9, the pressing member 1 may further include a limiting portion 13, the limiting portion 13 is disposed on one surface of the pressing portion 11 facing the pressing post 12, an avoidance groove and a limiting groove which are mutually communicated may be disposed on the housing 20, the avoidance groove is disposed on an outer surface of the housing 20, the limiting groove is disposed at one end of the avoidance groove far away from the outer surface of the housing 20, the limiting portion 13 movably penetrates through the avoidance groove and extends into the limiting groove, and a diameter of a circumscribed circle of a portion of the limiting portion 13 located in the limiting groove may be larger than a diameter of a circumscribed circle of one end of the avoidance groove facing the limiting groove, so that one end of the limiting portion 13 far away from the pressing portion 11 can only move in the limiting groove, thereby effectively preventing the pressing member 1 from slipping from the key groove 201.

Example two

The embodiment of the application also discloses a terminal, as shown in fig. 10-12, comprising a housing 20 and a key 10 according to any one of the embodiments, wherein the housing 20 is provided with a key groove 201, the key 10 is accommodated in the key groove 201, and the pressing piece 1 is slidably arranged in the key groove 201.

In this embodiment, the key 10 in the terminal 100 is the key 10 in the first embodiment, so the key 10 in this embodiment has substantially the same technical effects as the key 10 in the first embodiment, and the technical effects of the key 10 in the first embodiment are described more fully, so that the description thereof will not be repeated here.

Wherein, the key groove 201 of holding button 10 can include the first keyway of pressing and the second of mutual intercommunication presses the keyway, the first keyway of pressing can be with the outside intercommunication of casing 20, the second is pressed the keyway and can be linked together with the inside space of casing 20, wherein, parcel support 2 can inlay and locate in the second presses the keyway, press piece 1 slidable holding in the first keyway of pressing, and the cross-sectional area of pressing the keyway of first can be less than the second and press the cross-sectional area of keyway for the first one end of pressing the keyway towards the second of pressing can form the step face, so that parcel support 2 can be spacing in the second presses the keyway, the installation of parcel support 2 has been made things convenient for.

The terminal 100 may be any of a mobile phone, a tablet, a bracelet, a notebook, an electronic toy, etc., and is not limited thereto.

In addition, when the pressing member 1 includes the pressing post 12 and the pressing portion 11, the first pressing key groove may include a first sub-pressing key groove and a second sub-pressing key groove which are mutually communicated, the pressing portion 11 is slidably received in the first sub-pressing key groove, the pressing post 12 is slidably received in the second sub-pressing key groove, and the cross-sectional area of the first sub-pressing key groove may be slightly larger than the cross-sectional area of the pressing portion 11, the cross-sectional area of the second sub-pressing key groove may be slightly larger than the cross-sectional area of the pressing post 12, and the cross-sectional area of the first sub-pressing key groove is larger than the cross-sectional area of the second sub-pressing key groove, thereby preventing the pressing member 1 from sliding into the pressing key groove 201 toward the direction of the wrapping bracket 2, and facilitating pressing the pressing member 1.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
