Abstract:
The electrical connector system comprises a substrate (1) connected to PHY side and an electrical connector (3) mounted on the substrate (1), a transformer (5) and a common mode filter (7). The electrical connector (3) is used to mate with a cable assembly and so forms a Cable side. The transformer (5) further comprises a first wire (51) having two opposite ends electrically connected to the PHY side and a second wire (53) having two opposite ends. The common mode filter (7) having a third wire (73) and a fourth wire (75) that are physically separated from the second wire (53). The third wire (73) has an end electrically connected to one end of the second wire (53) and an opposite end electrically connected to the Cable side. The fourth wire (75) has an end electrically connected to the opposite end of the second wire (53) and an opposite end electrically connected to the Cable side.

Abstract:
A magnetics assembly (100) including a transformer (1) made of litz wire. The transformer includes a toroid core (2) and a bundle of wires (3) winding around the toroid core. The bundle of wires includes a first to eighth wires, and has a central portion with all eight wires twisted together and winding around the toroid core. A first and a second ends of the bundle of wires oppositely extend out from the toroidal core. The ends of the first to eighth wires are connected to form a primary and a secondary coils of the transformer, each of the primary and secondary coils having a central tap (35, 36) and carrying circuit in multiple wires.
Abstract:
A thermal module assembly includes a first thermal module (10) and a second thermal module (20). The first thermal module (10) has a fan (300) with an air outlet, a first heat sink (120) positioned at the air outlet and a first clamp portion (122) formed on the first heat sink (120). The second thermal module (20) has a second heat sink (220) and a second clamp portion (222) formed on the second heat sink (220). The second heat sink (220) is juxtaposed with the first heat sink (120). The first heat sink (120) and the second heat sink (220) are combined together via engagement of the first clamp portion (122) and the second clamp portion (222) so that airflow produced by the fan (300) flows past the first heat sink (120) and the second heat sink (220) in order.
Abstract:
A mounting apparatus includes a bracket, a frame slidably received in the bracket, a fixing member mounted inside the frame for fixing a storage device to the frame, at least one gasket, and at least one fastener for extending through the at least one gasket and the frame to engage with the fixing member, the at least one gasket dampening vibrations transmitted from the frame to the storage device along the at least one fastener and the fixing member.
Abstract:
A mouse device includes a lower case, a circuit board mounted to the lower case, an intermediate plate secured with the circuit board, a keyboard with a plurality of keys thereon, an upper case coupled to the lower case, and at least one key lock secured to the intermediate plate. The circuit board includes a plurality of contact switches thereon. The keys are aligned with the contact switches to activate the contact switches. The upper case defines a plurality of holes to allow the keys of the keyboard to extend therethrough. The key lock is selectively engaged with two different positions of the lower case to lift or lower the circuit board so as to lift or lower the keys for making the keys protrusive from the upper case or received in the upper case.
