Abstract: A circuit board includes an insulating substrate layer, a ground layer, an insulating layer, insulating through holes, a signal transmission layer and a polymer conductive member. The ground layer is disposed between the insulating layer and the insulating substrate layer. The signal transmission layer is disposed on one side of the insulating layer opposite to the ground layer. The insulating through holes penetrate through the signal transmission layer and the insulation layer to connect to the ground layer. The polymer conductive member is disposed within the insulating through holes, and one part thereof is electrically connected to the ground layer, and another part thereof extends outwards from the signal transmission layer.

Abstract: A connector assembly includes a wire end connector for electrically connecting to a board end connector. The wire end connector includes a main body portion and an insertion portion. The insertion portion is connected to the main body portion, and the insertion portion is configured to couple to the board end connector. The main body portion is provided with a plurality of elastic claws extending outward from the main body portion to press on the board end connector when the insertion portion is coupled to the board end connector so as to stably connect the wire end connector to the board end connector.

Abstract: A cable connector configured to secure a cable is provided. The cable connector has a casing, a latch, and a pulling member. The casing is configured to secure an end of the cable. The latch has a lower portion and an upper portion. The lower portion is secured on the casing and has a lower through hole. The upper portion has at least one upper through hole and at least one protrusion. The pulling member is connected with the upper through hole and penetrates the lower through hole. While the pulling member is pulled away from the latch along a first direction, the pulling member pulls the upper portion toward the lower portion along a second direction, so as to adjust a position of the protrusion. Thus, the latch may not be separated from the casing when a user pulls the pulling member.

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.

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: An electronic connector has a first shell, a second shell, a space, and at least one fixing unit. The first shell has a cover segment and at least one first assembling segment mounted securely on the cover segment. The second shell has at least one second assembling segment arranged with the first assembling segment of the first shell along the width direction of the electronic connector. The space is formed between the cover segment of the first shell and the second shell. The first assembling segment of the first shell is located in the space. The fixing unit is mounted through the first assembling segment of the first shell and the second assembling segment of the second shell along the width direction. Therefore, wires will not be restricted by the first assembling segment and the second assembling segment in the width direction.

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: An interface card is provided with an oblique-insert-proof structure. The interface card has an inserting portion configured to be inserted into a slot of a motherboard. The oblique-insert-proof structure is configured to abut the slot. The oblique-insert-proof structure has a connecting portion and two end blocking portions. The connecting portion has a groove in an inserting direction and extending in a length direction. The end blocking portions are configured to abut two shorter side surfaces of the slot. The oblique-insert-proof structure is securely mounted on the interface card and the inserting portion is mounted through the groove. When the interface card is mounted on the motherboard, the oblique-insert-proof structure can assist in aligning the inserting portion with the slot. 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.
