Abstract
The utility model discloses a metal spring piece of a mobile phone key, which comprises a fixed part, a contact part and an elastic part connected between the fixed part and the contact part; the fixed part is formed with the extension in the one end of being connected with the elastic part, is equipped with supplementary stretch-panel between this extension and the elastic part, supplementary stretch-panel is used for providing the elasticity that drives the elastic part and reset, and the bottom and the extension fixed connection of this supplementary stretch-panel, and the top of this supplementary stretch-panel is leaned on with the elastic part mutually. The metal elastic sheet of the mobile phone key has reasonable structure, and the problem that normal use is affected due to the weakening of elasticity of the metal elastic sheet is avoided by additionally arranging the auxiliary elastic sheet.
Description
Technical Field
The utility model relates to a metal spring plate of a mobile phone key.
Background
With the development of society and the progress of communication technology, communication products such as mobile phones have become an important communication tool for people. Along with the increasingly frequent use of mobile phones, the demands of people on mobile phones are also increasing. Currently, a metal spring is usually disposed between a mobile phone circuit board and a key. The metal spring plate in the prior art comprises a fixed part and a contact part, and an elastic part connected between the fixed part and the contact part; the fixed part is used for being fixedly connected with the mobile phone circuit board, and when the mobile phone is used, a user presses the contact part by pressing the key, so that the elastic part deforms and is contacted and conducted with the mobile phone circuit board by the contact part, and the mobile phone key works. However, the metal spring sheet in the prior art can be weakened in elasticity after long-time use, so that normal use is affected.
Disclosure of Invention
The utility model aims to provide a metal elastic sheet of a mobile phone key, which has a reasonable structure, and the problem that normal use is affected due to the weakening of elasticity of the metal elastic sheet is avoided by additionally arranging an auxiliary elastic sheet.
In order to achieve the above purpose, the technical scheme of the utility model is to design a metal spring piece of a mobile phone key, which comprises a fixing part, a contact part and an elastic part connected between the fixing part and the contact part; the fixed part is formed with the extension in the one end of being connected with the elastic part, is equipped with supplementary stretch-panel between this extension and the elastic part, supplementary stretch-panel is used for providing the elasticity that drives the elastic part and reset, and the bottom and the extension fixed connection of this supplementary stretch-panel, and the top of this supplementary stretch-panel is leaned on with the elastic part mutually.
Preferably, the auxiliary elastic sheet is in a C-shaped structure.
Preferably, the auxiliary elastic sheet is a metal sheet, and is fixedly connected with the extension part in a welding manner.
Preferably, a reinforcing rib is arranged between the fixing part and the elastic part.
Preferably, positioning grooves are respectively arranged on two sides of the fixing part.
The utility model has the advantages and beneficial effects that: the metal elastic sheet is reasonable in structure, the auxiliary elastic sheet is additionally arranged, the elastic sheet is used for providing the elastic force for driving the elastic part to reset, the situation that the elastic part is not in place due to rebound is avoided, and the problem that normal use is affected due to the fact that the elasticity of the metal elastic sheet is weakened is further avoided.
Drawings
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is an enlarged view at a in fig. 1.
Detailed Description
The following describes the embodiments of the present utility model further with reference to the drawings and examples. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and are not intended to limit the scope of the present utility model.
The technical scheme of the utility model is as follows:
as shown in fig. 1 and 2, a metal spring sheet of a mobile phone key comprises a fixing part 1, a contact part 2, and an elastic part 3 connected between the fixing part 1 and the contact part 2; the fixing part 1 is provided with an extension part 11 at one end connected with the elastic part 3, an auxiliary elastic piece 4 is arranged between the extension part 11 and the elastic part 3, the auxiliary elastic piece 4 is used for providing elastic force for driving the elastic part 3 to reset, the bottom of the auxiliary elastic piece 4 is fixedly connected with the extension part 11, and the top of the auxiliary elastic piece 4 is abutted against the elastic part 3. In the above scheme, the metal spring plate is fixedly connected with the mobile phone circuit board through the fixing part 1. When a user presses a mobile phone key, the mobile phone key presses the contact part 2, so that the elastic part 3 bends towards the mobile phone circuit board and presses the auxiliary elastic piece 4 to deform until the contact part 2 is in contact conduction with the mobile phone circuit board, and the mobile phone key works; when the user releases the mobile phone key, the auxiliary elastic sheet 4 rebounds, and the auxiliary elastic sheet 4 rebounds and resets the extrusion elastic part 3, so that the condition that the rebound is not in place due to the weakening of the elasticity of the elastic part 3 is avoided.
Further, the auxiliary elastic sheet 4 has a C-shaped structure.
Further, the auxiliary elastic piece 4 is a metal sheet, and the auxiliary elastic piece 4 is fixedly connected with the extension portion 11 through a welding manner.
Further, a reinforcing rib 5 is provided between the fixing portion 1 and the elastic portion 2. By adopting the scheme, the connection strength between the fixed part 1 and the elastic part 3 is improved.
Further, positioning grooves 12 are respectively provided on both sides of the fixing portion 1. By adopting the scheme, the fixing part 1 can be positioned and installed with the mobile phone circuit board through the positioning groove 12.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several modifications and variations can be made without departing from the technical principle of the present utility model, and these modifications and variations should also be regarded as the scope of the utility model.
