Patent number: 8431837Abstract: A waterproof jacket assembly applied in a communication device is disclosed. The communication device includes an enclosure defining a first through hole for a transmission wire passing through. The waterproof jacket assembly is mounted on the enclosure corresponding to the first through hole, and includes a sleeve, an elastic waterproof element and a cover board. The sleeve defines a receiving cavity in communication with the first through hole. The elastic waterproof element is received in the receiving cavity and helically wrapped around the transmission wire. The transmission wire passes through the cover board and the cover board engages with the sleeve to drive the elastic waterproof element to fill in the receiving cavity.Type: GrantFiled: November 29, 2010Date of Patent: April 30, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Chung-Jun Chu

Publication number: 20110255247Abstract: A heat sink assembly with shielding frame is mounted on a circuit board and includes a heat sink, a shielding frame and a heat transmitting film. The circuit board comprises at least one electronic component and a plurality of latching slots surrounding the electronic component. The heat sink includes a base and a plurality of heat fins extending upwardly from the base. A plurality of slots are defined between the plurality of heat fins. The shielding frame includes a hollow frame, a plurality of latch portions and a plurality of limitation portions. The plurality of latch portions are disposed on one end of the hollow frame and evenly spaced apart from each other. The plurality of limitation portions extend from the other end of the hollow frame. The shielding frame cooperates with the heat sink to shield the electronic component from electromagnetic interference (EMI).Type: ApplicationFiled: August 9, 2010Publication date: October 20, 2011Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventor: Chung-Jun CHU

Patent number: 7845395Abstract: A heat-dissipating casing structure includes a base seat, a heat-dissipating module, and a casing. The heat-dissipating module is disposed on the base seat. The heat-dissipating module has a first heat-conducting block and a heat pipe, and one side of the heat pipe connects to the first heat-conducting block. The casing has an installed portion, and the casing is slidably assembled on the base seat for connecting the other side of the heat pipe with the casing via the installed portion. When the casing is slidably assembled on the base seat, the heat pipe is connected with the casing via the installed portion. Hence, the heat-dissipating module is assembled and replaced easily and rapidly. Moreover, the heat from a heat-generating element on the base seat is transmitted to the casing through the heat pipe for increasing heat-dissipating efficiency.Type: GrantFiled: July 2, 2007Date of Patent: December 7, 2010Assignee: Cooler Master Co., Ltd.Inventor: Chung-Jun Chu

Publication number: 20090229808Abstract: A heat-conducting assembly is mounted between a heat-generating element and a heat-dissipating plate. The heat-conducting assembly includes a base, a first heat-conducting block, a second heat-conducting block and an elastic element. The base is attached on the heat-generating element. The first heat-conducting block is provided on the base. The first heat-conducting block has a first slope and a fixing groove. The second heat-conducting block abuts on the heat-dissipating plate. The second heat-conducting block has a second slope and a locking groove. The second slope is slidingly disposed on the first slope. The elastic element has a fixed end and a buckling end formed on one side of the fixed end. The fixed end is fixed in the fixing groove, and the buckling end is buckled into the locking groove. Via this arrangement, the heat-conducting efficiency of the heat-conducting assembly of the present invention can be improved.Type: ApplicationFiled: January 7, 2009Publication date: September 17, 2009Inventor: Chung-Jun CHU
