摘要： AN ELECTRICAL CONNECTOR ASSEMBLY (30) HAVING A LOW INSERTION FORCE HIGH NORMAL FORCE MATING CONTACT STRUCTURE (10) COMPRISING A MALE TERMINAL (34) AND A FEMALE TERMINAL (20). THE MALE TERMINAL IS AN ELONGATE CONDUCTOR INCLUDING A FINAL CONTACT AREA (36) JOINING A FORWARDLY EXTENDING LEAD-IN PORTION (38, 40). THE FEMALE TERMINAL INCLUDES DUAL-CANTILEVER SPRING ARMS (24, 26) WITH MUTUALLY OPPOSING CONTACT PORTIONS (24B, 26B) WHICH DEFINE A LEAD-IN MOUTH THEREBETWEEN. THE CONTACT PORTIONS OF THE FEMALE TERMINAL ARE ADAPTED TO ELECTRICALLY ENGAGE THE LEAD-IN PORTION OF THE MALE TERMINAL AS THE MALE TERMINAL IS INSERTED INTO THE MOUTH BETWEEN THE CONTACT PORTIONS OF THE FEMALE TERMINAL. THE LEAD-IN PORTION OF THE MALE TERMINAL IS SPLIT AND DEFINES A PAIR OF DIVERGING BEAMS (38, 40) EXTENDING FORWARDLY AND ANGLED OUTWARDLY FORM THE FINAL CONTACT AREA (36). THE BEAMS HAVE INWARDLY FACING, LATERALLY OFFSET, OPPOSING CAMMING PORTIONS (38B, 40B) ADAPTED TO ENGAGE AND INCREASINGLY DEFLECT THE CONTACT PORTIONS OF THE SPRING ARMS OF THE FEMALE TERMINAL AS THE MALE TERMINAL IS MOVED FROM AN INITIAL POSITION TO A FINAL POSITION WHEREIN THE FEMALE CONTACT PORTIONS ARE IN ENGAGEMENT WITH THE FINAL CONTACT AREA OF THE MALE TERMINAL. THE NORMAL FORCE BETWEEN THE CONTACT PORTION OF THE SPRING ARM AND THE CORRESPONDING CAMMING PORTION GRADUALLY INCREASES UNTIL THE FINAL MATED POSITION IS ACHIEVED. THE SPLIT MALE CONFIGURATION ALLOWS FOR INCREASED TERMINAL MATING LENGTH AND ADJUSTMENT OF THE WIPING ACTION OF THE CONTACTS AS DESIRED.(FIG 2)

摘要： A METHOD AND STRUCTURE OF AN ELECTRICAL CONNECTOR (10) IS PROVIDED FOR TUNING THE IMPEDANCE OF THE CONNECTOR ACCORDING TO A GIVEN IMPEDANCE OF AN ELECTRICAL CIRCUIT IN WHICH THE CONNECTOR IS INTERCONNECTED. THE CONNECTOR INCLUDES A DIELECTRIC HOUSING (16) HAVING A RECEPTACLE (12) FOR RECEIVING A COMPLEMENTARY MATING CONNECTOR. A PLURALITY OF TERMINALS (12) ARE MOUNTED ON THE HOUSING. THE TERMINALS INCLUDE BODY PORTIONS (32) LOCATED IN THE HOUSING AND CONTACT PORTIONS (42) LOCATED AT THE RECEPTACLE FOR ENGAGING APPROPRIATE TERMINALS OF THE MATING CONNECTOR WHEN INSERTED INTO THE RECEPTACLE. THE AREAS (34, 34'', 34", 34'''''') OF THE BODY PORTIONS OF THE TERMINALS ARE SELECTIVELY VARIED TO VARY THE CAPACITANCE OF THE TERMINALS AND, THEREFORE, THE IMPEDANCE OF THE CONNECTOR TO MATCH THE GIVEN IMPEDANCE OF THE ELECTRICAL CIRCUIT. WHEN THE CONNECTOR IS USED FOR MOUNTING TO A PRINTED CIRCUIT BOARD, GROUND TERMINALS (30) HAVE AT LEAST TWO FEET (36) FOR ENGAGING A RESPECTIVE SINGLE GROUND TRACE OF A COMMON GROUND CIRCUIT ON THE PRINTED CIRCUIT BOARD FOR REDUCING THE INDUCTANCE BETWEEN A PARTICULAR GROUND TERMINAL AND ITS RESPECTIVE CIRCUIT TRACE.(FIG 1)

摘要： AN EDGE CONNECTOR (20) IS PROVIDED FOR A PRINTED CIRCUIT BOARD (94) HAVING A MATING EDGE (94A) AND A PLURALITY OF CONTACT PADS ADJACENT THE EDGE. THE CONNECTOR INCLUDES AN ELONGATED DIELECTRIC HOUSING (22) HAVING A BOARD-RECEIVING SLOT (24) FOR RECEIVING THE MATING EDGE OF THE PRINTED CIRCUIT BOARD. A PLURALITY OF SPRING CONTACT ELEMENTS (48, 50) ARE MOUNTED IN THE HOUSING ALONG AT LEAST ONE SIDE OF THE SLOT. THE SPRING CONTACT ELEMENTS HAVE SPRING CONTACT PORTIONS (48A, 50A) EXTENDING INTO THE SLOT FOR CONTACTING RESPECTIVE ONES OF THE CONTACT PADS ON THE PRINTED CIRCUIT BOARD. A SURFACE (52) ON THE HOUSING AT THE ONE SIDE OF THE DEFINES A DATUM PLANE BEYOND WHICH THE SPRING CONTACT PORTION OF AT LEAST ONE OF THE SPRING CONTACT ELEMENTS EXTENDS INTO THE SLOT. A BIASING SPRING (58, 66, 78, 114) BIASES THE PRINTED CIRCUIT BOARD AGAINST THE SURFACE, THEREBY DEFLECTING THE SPRING CONTACT PORTION OF THE AT LEAST ONE SPRING CONTACT ELEMENT A PREDETERMINED AMOUNT.(FIG 7)

摘要： A METHOD AND STRUCTURE OF AN ELECTRICAL CONNECTOR (10) IS PROVIDED FOR TUNING THE IMPEDANCE OF THE CONNECTOR ACCORDING TO A GIVEN IMPEDANCE OF AN ELECTRICAL CIRCUIT IN WHICH THE CONNECTOR IS INTERCONNECTED. THE CONNECTOR INCLUDES A DIELECTRIC HOUSING (16) HAVING A RECEPTACLE (12) FOR RECEIVING A COMPLEMENTARY ELECTRICAL COMPONENT (13). A PLURALITY OF TERMINALS (28, 30) ARE MOUNTED ON THE HOUSING.THE TERMINALS INCLUDE BODY PORTIONS (32, 48) LOCATED IN THE HOUSING AND CONTACT PORTIONS (34, 50) FOR ENGAGING RESPECTIVE CONTACTS (17A, 17B) ON THE ELECTRICAL COMPONENT. THE BODY PORTIONS INLCUDE MECHANICALLY NON- FUNCTIONAL SECTIONS (40) OF A GIVEN AREA WHICH EFFECT A GIVEN CAPACITANCE. THE MECHANICALLY NON- FUNCTIONAL SECTIONS ARE SELECTIVELY TRIMMABLE TO SELECTIVELY VARY THE AREA THEREOF AND THEREBY VARY THE CAPACITANCE OF THE TERMINALS AND, THEREFORE, THE IMPEDANCE OF THE CONNECTOR TO MATCH THE GIVEN IMPEDANCE OF THE ELECTRICAL CIRCUIT. THE CONNECTOR INLCUDES A PLURALITY OF SIGNAL TERMINALS (28) AND A PLURALITY OF GROUND TERMINALS (30). THE SIGNAL TERMINALS AND GROUND TERMINALS ARE IN AN ALTERNATING ARRAY LENGTHWISE ALONG THE RECEPTACLE, WITH EACH SIGNAL TERMINAL BEING ALIGNED WITH A GROUND TERMINALS ON OPPOSITE TRANSVERSE SIDES OF THE RECEPTACLE, AND THE GROUND TERMINALS HAVE SIGNIFICANTLY LARGER TRANSVERSE AREAS THAN THE SIGNAL TERMINALS. THE GROUND TERMINALS HAVE AT LEAST TWO POINTS (57, 60) OF CONTACT FOR ENGAGING A COMMON GROUND CIRCUIT ON THE PRINTED CIRCUIT BOARD FOR REDUCING THE INDUCTANCE BETWEEN A PARTICULAR GROUND TERMINAL AND THIS RESPECTIVE CIRCUIT TRACE.(FIG. 4)
