Abstract: A connector has a case, a circuit board, a thermal diffusing unit, and a first heat sink. The circuit board is mounted in the case and has a heating source. The thermal diffusing unit abuts the inner surface of the case and the heating source of the circuit board. A heat transfer coefficient of the thermal diffusing unit is larger than a heat transfer coefficient of the case. The first heat sink abuts the thermal diffusing unit and is exposed from the case. A heat transfer coefficient of the first heat sink is larger than the heat transfer coefficient of the case. By the first heat sink abutting the thermal diffusing unit and exposed from the case, and the heat transfer coefficients of both the thermal diffusing unit and the first heat sink being larger than that of the case, the heat dissipation efficiency is improved.

Abstract: A connector has a case, a circuit board, and a thermal diffusing unit. The case has an inner surface. The circuit board is mounted in the case and has a heating source. The thermal diffusing unit abuts the inner surface of the case and the heating source of the circuit board. An area of the thermal diffusing unit abutting the inner surface is bigger than an area of the thermal diffusing unit abutting the heating source. A heat transfer coefficient of the thermal diffusing unit is bigger than a heat transfer coefficient of the case. With the structure above, the thermal diffusing unit is allowed to transmit heat from a small area to a big area, thereby improving the heat dissipation efficiency of the connector.

Abstract: A connector has a casing and a circuit board structure. The circuit board structure is mounted through the casing and has a board main body, a projecting body, and multiple metal electrodes. The projecting body is mounted on a connecting end surface of the board main body and projects from the connecting end surface in an insertion direction of the connector. When the connector is connected to another device, the projecting body of the circuit board structure may push a part of pins of the device first, so the user may exert less force to insert the projecting body into the device. Then, when the circuit board structure is inserted further, the board main body may abut the remaining pins. Because part of the pins have been pushed away by the projecting body, the board main body only needs to counteract resistance from the remaining pins.

Abstract: An electronic device connection system has a cable, a cable connector, and an electronic device. The electronic device has a socket. When the cable connector is mounted through the socket, the cable is electrically connected to the electronic device. The cable connector has a casing, a resilient latch, and a pulling member. The casing forms a protrusion and a first engaged opening. The resilient latch forms a hooked opening and a first hook. The protrusion can be engaged in the hooked opening, and the first hook can be engaged in the first engaged opening so the resilient latch is firmly fixed on the casing. Thus, the resilient latch may not be separated from the casing when a user pulls the pulling member, which ensures that the casing will be detached from the socket when the pulling member is pulled.

Abstract: A circuit board assembly has a circuit board and a high-speed cable. The high-speed cable has two signal lines, a ground conductor, an impedance-reducing conductor, and a covering material. The signal lines, the ground conductor, and the impedance-reducing conductor are mounted through the entire high-speed cable. The covering material wraps the signal lines, the ground conductor, and the impedance-reducing conductor, and has a conductive layer and an isolation layer as an inner layer and an outer layer respectively. The conductive layer has multiple loops electrically connected to the ground conductor and the impedance-reducing conductor. Thus, the impedance in the covering material, the ground conductor, and the impedance-reducing conductor is decreased, which prevents from attenuating the signal intensity during transmission at high frequency.

Also, the oblique-insert-proof structure can enhance the strength of the connection between the interface card and the motherboard, so the interface card can be disposed with more components and bear more weight.
