PROBLEM TO BE SOLVED: To provide a simple and efficient square connector for a coaxial cable. SOLUTION: This connector has at least a pair of square coaxial conductors 28, 30 having the first and the second legs 32, 34 respectively joined with elbows 36. Tips 32a of the first support legs 32 respectively determine a contact end of each conductor. Tips 34 a of the second support legs 34 respectively determine a terminal to be mounted on a printed circuit board. A dielectric sheath 26 is arranged in the circumference of each square coaxial conductor with the tip of the coaxial conductor exposed. Tubular conductive shields 14, 38 are installed in the circumference of respective dielectric sheaths. Grounding means 18, 60 are made to join shields with the printed circuit board. An integrated dielectric housing 16 is arranged in the circumference of at least a part 38 of the shields 14, 38 in order to retain the connector within a module.

PROBLEM TO BE SOLVED: To provide a novel and improved heat sink holder and a heat sink assembly using the same. SOLUTION: A heat sink assembly 10 is provided with a heat exchange part 20 equipped with a heat-conductive sheet and the heat-conductive sheet is folded into alternate projections and recesses and forms a cylindrical fin as a whole. The recesses form an internal segmented cylinder, the projections form an external segmented cylinder almost concentric with this internal cylinder, and the f in is radially extended outward from an axis. A heat-conductive core 52 is provided inside the internal segmented cylinder and conducts heat to be diffused away from a heat generating component to the heat exchange part. A holder 18 is engaged to the cylindrical folded sheet at the second edge of the fin. The heat exchange part 20 is attached to a base plate 22, a complementary mutual engage latch 30 is provided between the holder 18 and the base plate 20 and the heat exchange part 20 is held between them.

PROBLEM TO BE SOLVED: To provide a connector that facilitates manufacturing while still providing a dense, high-performance connector.SOLUTION: A connector 600 of horizontal construction includes at least a pair of first and second halves that are mated together along a common mating line. A plurality of mating blades 607 are supported in a vertical arrangement within a mating portion of the connector. The connector includes two distinct fastenings means for holding housing halves 610 and 611 together. First fastening means is provided as a horizontal attachment member 612 that extends widthwise in the mating portion in a space between circuit cards 607. Second fastening means is provided as an exterior retainer 620 that engages at least part of the outer circumference, or perimeter of the connector.
Abstract:
PROBLEM TO BE SOLVED: To provide a connector system suited to manage thermal loads.SOLUTION: A connector includes a heat spreader. The heat spreader is configured to direct heat from ports to a thermal plate that is disposed apart from the connector. A plurality of such connectors can be supported and the heat spreaders can be linked with each of the connectors. One or more thermal plates can be thermally coupled to the corresponding heat spreaders so as to direct thermal energy away from each connector. Cold blocks can be used to thermally couple the heat spreaders to the corresponding thermal plates.
Abstract:
PROBLEM TO BE SOLVED: To provide a technique for designing a circuit board useful for high-speed differential signal applications. SOLUTION: In a via arrangement, differential signal pair vias and an associated grounding are arranged adjacent to each other in a repeating pattern. The differential signal vias of each pair are spaced at regular intervals closer to their associated grounding vias than the spacing between the adjacent differential signal pair associated grounding so that the differential signal vias exhibit preference for electrical coupling to their associated grounding vias. A circuit trace exit structure includes the exit portions of circuit traces of the differential signal vias to follow a path where the traces then meet with and join to the transmission line portions of the conductive traces.

Abstract:
PROBLEM TO BE SOLVED: To provide an edge card connector for a printed circuit board having a terminal constitution increasing density of a terminal by forming a tail of the terminal cross in two rows. SOLUTION: A long narrow insulating housing 22 of an edge card connector 20 receiving an edge of a printed circuit board having a contact pad has a board receiving surface 22b, long narrow slot 24 receiving the edge of the printed circuit board, and terminal receiving cavities 38a, 38b. In the terminal receiving cavity, terminals 58a, 58b are received. Both the terminals include tails 64, 74, contact parts 66b, 76e and elastic spring arms 66, 76 having a holding part. Hollows 46, 52 formed in a traversing wall 40 are formed in arrangement and size receiving protrusions 68 and 78 protruded from the terminal received in the cavity, the size is formed sufficiently for the spring arm of the terminal in a region of the protrusion so as to be capable of freely moving relating to the housing.
Abstract:
An electrical connector includes a housing having a mating face and a pair of first and second aligned openings. Each opening is configured to receive a mateable component therein. A plurality of electrically conductive contacts are provided for engaging contacts of a mateable component. A circuit member has a generally planar conductive reference plane extending between forward and rearward ends thereof. A forward portion of the reference plane is located between at least half of the pair of first and second aligned openings.

Abstract:
A connector assembly is provided with opposing and interengageable first and second connector components. Each of the two components has internal cavities that contain terminal assemblies of either plug or receptacle structure and may further include either a plurality of power terminals or differential signal terminals. The terminals have contact portions, tail portions and interconnecting portions that are partially encapsulated by an insulative outer support frames. The shell forms a wafer and two such wafers are combined together to form a terminal assembly. The terminal assemblies are identical in shape, other than for an engagement means that serves to hold two subframes together as a single assembly.
