Abstract: An electronic device includes a main body defining an opening, and a key mechanism secured in the opening. The key mechanism includes a fixing mechanism, a circuit board and a key. The fixing mechanism includes a tab and a support. The tab protrudes from a sidewall of the opening. The support includes an elastic supporting rib connected to the tab. The circuit board is fixed on the support and includes a switch. The key is rotatably connected to the fixing mechanism actuates the switch to generate an input signal. The supporting rib applies a restoring force to the key.

Abstract: A push button assembly for use in an electronic device includes a plate, a circuit board, an elongated button and an elastic element. The plate is arranged within the electronic device. The circuit board is fixed to the plate. The circuit board includes a switch. The elastic element is fixed to the plate. The elastic element includes an elongated depressible portion arranged between the circuit board and the button. The depressible portion extends along a lengthwise direction of the button and is deformable by depression of elongated button. The disclosure also provides an electronic device having the push button assembly.

Abstract: An electronic device includes a housing, a circuit board disposed in the housing, a female connector received in the housing, and a switch. The female connector is configured to receive and electrically connect a male connector, including a through hole, the through hole having a first opening exposed outside the housing for insertion of the male connector into the through hole therethrough and an opposing second opening located within the housing, the second opening aligned with the first opening. The switch is electrically connected to the circuit board adjacent to the second opening. The switch is able to be actuated by an elongated object passing through the second opening, and the electronic device is rebooted when the switch is actuated.

Abstract: An electronic device includes a main body, a panel mounted on the main body, and a substrate disposed between the main body and the panel. The substrate is configured for carrying touch sensors, and is connected to the panel. The electronic device further includes elastic arms extended from the main body, bearing resilient against the substrate. The touch sensors are mounted in the electronic device reliably.

Abstract: A weld nut includes a main body and a flange. The flange is extended outwardly from the main body and surrounding the main body, and comprises teeth disposed evenly on the periphery thereof. Mis-positioning of the weld nut is avoided when soldering the weld nut to a printed circuit board.

Abstract: An electronic device includes an upper cover, bottom cover and locking mechanism to connect the upper cover to the bottom cover. The locking mechanism includes a plurality of protrusions formed on an inner surface of the bottom cover, elastic members and a blade. The blade is slidably mounted on the upper cover and capable of being attracted by an external magnetic member. The blade is formed with hooks. Each protrusion defines a notch. The hooks are urged by the elastic members to be received in the notch and connect the upper cover to the bottom cover. The hooks are capable of moving out of the notches by the force of the external magnetic member, allowing the upper cover to detach from the bottom cover. A locking mechanism configured for connecting an upper cover to a bottom cover is also provided.

Abstract: A shield device includes a clip, which includes a base, two sidewalls and two clamping members. The two sidewalls extend upward from two opposite edges of the base, and the two clamping members extend upward and inward from the top of the sidewalls. The clamping members define a plurality of first clamping elements and a plurality of second clamping elements. Two opposite ones of the first clamping elements are spaced from each other at a first distance, two opposite ones of the second clamping elements are spaced from each other at a second distance, and the first distance is greater than the second distance.

The flange is extended outwardly from the main body and surrounding the main body, and comprises teeth disposed evenly on the periphery thereof. Mis-positioning of the weld nut is avoided when soldering the weld nut to a printed circuit board.

Abstract: An elastic contact includes a first elastic piece and a second elastic piece. The first elastic piece includes a base configured for being soldered to a circuit board and a connection part. The second elastic piece includes a contact part configured for resiliently pressing against an element and a connection part. Two sidewalls of one of the connection part bend to form grooves for receiving the other connection part. Limiting means are formed on either of the connection parts for limiting sliding range of the elastic pieces relative to each other. The first elastic piece of the elastic contact can be soldered to the circuit board by a SMT machine, thus the assembly efficiency is improved.

The substrate is configured for carrying touch sensors, and is connected to the panel. The electronic device further includes elastic arms extended from the main body, bearing resilient against the substrate. The touch sensors are mounted in the electronic device reliably.

Abstract: An electronic device includes a panel, a light guide, and light sources. The panel defines a light area, and includes a transparent main body, an optical clear coating layer painted on the main body, and a light tight coating layer painted on the optical clear coating layer without covering the light area. The light guide is disposed beneath the panel. The light guide fills up the whole light area. The light sources are configured for illuminating the light guide.
