Key entry device with a deformable dome array
A recently filed patent (Publication Number: US20230281402A1) describes a key entry device with enhanced security features. The device includes a housing, a keypad array, a key contact array, a dome array, and a protective enclosure. The keypad array consists of multiple keys, while the key contact array is positioned below the keypad array and includes contact pairs aligned with each key. The dome array, also aligned with the keys and contact pairs, consists of domes that are deformed when a key is pressed. The protective enclosure includes an anti-tamper mesh that surrounds the key contact array and dome array, providing additional security. Additionally, the device features case open switch assemblies located within the protective enclosure, further enhancing its security measures.
The key entry device also includes a protrusion array underlying the dome array, with protrusions aligned with each dome. When a key is depressed, the corresponding dome is displaced downward and deformed by engaging with the corresponding protrusion, making contact with the contact pairs in the key contact array. This mechanism allows for the formation of electrical connections between the conductive ring and the conductive disk, resulting in enhanced functionality.
The key contact array is formed on a flexible printed circuit substrate and is positioned beneath the anti-tamper mesh. The anti-tamper mesh, which can consist of multiple meshes, provides an additional layer of protection against tampering. The device also includes elements that are integrally formed with the protrusion array and are directed in the opposite direction of the protrusions. These elements, along with the protective enclosure, ensure the security and integrity of the key entry device.
Overall, this patent describes a key entry device with improved security features, including anti-tamper measures and case open switch assemblies. The device's design allows for the deformation of domes and the formation of electrical connections, enhancing its functionality. The use of a protective enclosure and anti-tamper mesh provides additional security, making this key entry device suitable for applications where security is of utmost importance.
