Abstract: A locking mechanism for removably locking a first electrical component to a second electrical component includes a positioning post secured to the second electrical component, a frame for mounting the first electrical component, and a locking member movably connected with the frame. The positioning post has a head and a neck. The locking member has a snap fastening portion, a flexible portion and an unlocking operated portion. When the snap fastening portion contacts the head and is moved toward the neck, a lateral thrust force exerted by the head spreads the snap fastening portion and cause deformation of the flexible portion to store a biasing restoring force. When the snap fastening portion is aligned with the neck, the snap fastening portion is moved by the biasing restoring force to be snap fastened to the neck. The unlocking operated portion is operated to disengage the snap fastening portion from the neck.

Abstract: A luminous keyboard includes at least one key, a switch circuit board, a supporting plate, a backlight module, a reflecting plate and a light-sheltering plate. The backlight module emits a light beam. The backlight module is arranged between the reflecting plate and the light-sheltering plate. A periphery region of the reflecting plate and a periphery region of the light-sheltering plate are thermally laminated or laser welded to define a sealed structure. Since the periphery region of the backlight module is sealed by the sealed structure, the light beam is not leaked out through the periphery region of the backlight module. The space occupied by the sealed structure is not very large. Consequently, the volume of the luminous keyboard is reduced.

The membrane switch circuit member is located under the plural keys, and includes an upper wiring plate, a lower wiring plate and a separation plate. The supporting plate is located under the membrane switch circuit member and connected with the plural keys. The backlight module is located under the supporting plate to generate a light beam. A periphery region of at least one of the upper wiring plate, the lower wiring plate and the separation plate is bent to cover the supporting plate and the backlight module. Consequently, the light beam is not leaked out through the periphery region of the backlight module.

Abstract: The present invention relates to a keyboard, including a base plate, a connecting element, a keycap, and a hook. The connecting element is separately connected to the hook and the base plate. The hook is disposed on an inner surface of the keycap and is connected to a connecting shaft of the connecting element. The hook includes a first fixing portion and a second fixing portion. The first fixing portion is in contact with a first side of the connecting shaft, and the second fixing portion is in contact with a second side of the connecting shaft. The structure of the second fixing portion in the hook is stronger than the structure of the first fixing portion, so that when the connecting shaft is applied with a force to be out of the hook, the first fixing portion is applied with an interference force to be broken, thereby having a recognizing effect.

Abstract: The present invention provides an illuminated keyboard, including a plurality of keys, a metal plate, a thin film circuit board, and a backlight module. The metal plate includes a plurality of metal domes, disposed below the keys, and correspondingly located above a plurality of electrical contact parts of the thin film circuit board.
