Abstract: A fan module includes a mounting bracket, a fan and an anti-backflow device are detachably installed in the mounting bracket. The fan is configured to generate airflow along a predetermined direction, and the anti-backflow device allows the airflow to pass through. The fan is configured to generate airflow in another direction by being turned over, and the anti-backflow device allows the airflow in another direction to pass through be being turned over correspondingly. The anti-backflow device includes a louver assembly for one-way pass function. An electronic device comprising the fan module is also provided.

Abstract: A fan module includes a mounting bracket, a fan and a one-way shutter are detachably installed in the mounting bracket. The fan module is configured for installation at an electronic device along an insertion direction, the fan is configured to generate airflow along or opposite to the insertion direction, and the one-way shutter allows the airflow to pass through. The fan is configured to generate airflow in an opposite direction by being turned over, and the one-way shutter allows the airflow in the opposite direction to pass through by being turned over correspondingly. The one-way shutter includes a shutter base defining multiple guide holes, a baffle, and multiple float balls in the guide holes for allowing or preventing air to pass through the guide holes to achieve one-way pass function. An electronic device comprising the fan module is also provided.

Abstract: A heat-dissipation device with detachability against the adhesion of a paste includes a heat-dissipation structure and a detachment device. The heat-dissipation structure installed on a heat-generating component includes a base, and a heat-dissipation element disposed on the base, and a through hole penetrating through the base. The detachment device includes a housing disposed on the base and covering the through hole, wherein the housing includes a gas chamber, and a gas hole connected to the gas chamber, the gas hole being in communication with the through hole. An adjustment element is movably disposed in the gas chamber. A gas in the housing is pushed out through the gas hole by moving the adjustment element downwards, creating a positive gas pressure and thus forcing a separation between the heat-dissipation structure and the heat-generating component on which the structure is installed.

Abstract: A USB device includes a main body, a PCB fixed in the main body and a USB connector connected to the main body. The USB connector includes a shell, a USB plug and a cover. The shell defines a receiving room, a first opening and a second opening and includes an integrally formed enclosure enclosing the receiving room and a first flange outwardly protruding from the enclosure. The USB plug electrically connects to a wire group and is inserted into the shell from the first opening. The cover shields the second opening and is fixed to the shell. The cover includes a second flange engaging with the first flange to cooperatively receive the wire group and connect to the main body.

Abstract: An apparatus includes a connector and a connecting apparatus. The connector includes a first pin and a shell surrounding the first pin. The shell is insulated from the first pin. The connecting apparatus includes a main body, a second pin, and a third pin. The main body is connected to a bottom of the shell of the connector. First ends of the second and third pins extend through the main body, to be electrically connected to the first pin and the shell, respectively. Second ends of the second and third pins are exposed through a bottom of the main body.

Abstract: A network communication device includes a top component and a bottom cover forming a receiving space there between when assembled. The top component further includes a top cover and a body. The body is configured attaches the top cover and the bottom cover. The assembly of the top cover and the bottom cover utilizes at least one locking tab assembly. Each locking tab assembly includes a locking tab and a reciprocal locking structure engaged with the locking tab. One of the locking tabs and the reciprocal locking structure of the one locking tab assembly are utilized to assemble the top cover and the body is disposed on a first planar surface of the top cover, and another one of the locking tab and the reciprocal locking structure of the locking tab assembly is disposed on the body.

Abstract: An electronic device includes a housing and at least one light source. The housing defines a chamber therein and includes an inner surface defining at least one recess configured with a specified pattern. The at least one light source is fixed in the chamber and corresponds to the at least one recess. The at least one recess is transparent and the at least one light source transmits light to the at least one recess, thereby displaying the specified pattern on an outer surface opposite to the inner surface of the housing.

Abstract: An electronic device includes a housing and at least one light guide. The housing defines at least one through hole configured with a specified pattern. The light guides are fixed in the housing, and each light guide includes a protrusion configured with the same pattern structure as that of the through hole. The protrusions are received in the through holes. The at least one light guide transmits light from at least one light source to the protrusion thereof, thereby displaying the specified pattern of the protrusion on an outer surface of the housing.
