摘要:
A terminating connector for a data transmission cable, wherein the cable is of a known characteristic impedance and is of the type having a signal carrying conductor and a shield. The connector is typically arranged to mate with a complementary connector of a backplane. An overmolded subassembly of the connector includes a first terminal electrically coupled at one end thereof to the shield, and a second terminal electrically coupled at one end thereof to the signal carrying conductor. A dielectric insert is disposed between the first and second terminals. The insert is dimensioned and has a dielectric constant such that the characteristic impedance of the subassembly substantially matches the characteristic impedance of the cable. The subassembly may be secured to a surrounding housing.

In a motion insensitive coaxial cylindrical connector a male member has a substantially cylindrical body having a male or diameter and a substantially cylindrical stub having a minor diameter which stub extends from the body of the male member. The stub fits into a dielectric sleeve within a cavity in a female member. Preferably, the dielectric sleeve has two portions made of different dielectric materials.

An improved miniature interconnect (10) for detachably introducing a transmission line (12) to a corresponding medium (20) through a passage in a barrier (18). This interconnect (10) comprises a fastening means (36), coupled to the transmission line (12) for directly engaging the passage such that the transmission line (12) is removably retained in a held relationship with respect to the barrier (18). A conducting means (38) for establishing electrical contact between the transmission line (12) and the corresponding medium (20) is disposed within the passage and is engaged by both the transmission line (12) and the corresponding medium (20). This conducting means (38) further provides a sealing means (42) for sealing the passage through the barrier (18).
摘要:
A termination system for coupling to further circuitry one or more miniature coaxial cables terminated with respective impedance matched terminators each including a center signal contact and a concentric tubular sleeve contact having an external contact surface. The termination system includes a receptacle for a single terminator or a carrier block for a plurality of terminators. The receptacle includes a center pin contact extending along an axial extent of the receptacle, an outer tubular shell contact coaxially positioned with respect to the pin contact and having an internal contact surface for electrically connecting with the external contact surface of a terminator sleeve contact, and a spacer for maintaining electrical isolation and spaced relation of the pin and shell contacts for matching the impedance of the receptacle to that of the terminator and cable. The carrier block for a plurality of terminators is a conductive plate-like member having plural openings for receiving and electrically engaging with the external contact surface of respective terminator sleeve contacts thereby to couple the same to a common reference potential, such as ground reference potential, and is mountable and electrically connectable to a printed circuit board by a port member. The port member serves as a socket mount for the carrier block and, in the absence of a carrier block, serves to protect a plurality of pin contacts mounted to the printed circuit board for electrically connecting with the center signal contact of respective terminators held in the carrier block. Also disclosed are a resistance terminator and a shunt terminator.

A coaxial connector includes a housing carrying an insulator. The insulator carries a center contact with a spring biasing the cneter contact. A volute spring engages the housing and provides the ground or shield contact. The housing is formed of two halves with the volute spring and alignment pins holding the housing halves together. A coaxial cable has its shield clamped between the housing halves for providing the ground connection to the volute spring. The coaxial cable center conductor is connected to the center contact within the housing.

A support structure for a coaxial transmission line includes a plurality of groups of dielectric balls compressibly mounted between the inner and outer conductors of the coaxial transmission line, the balls being "locked" into position via recesses located in the outer face of the inner conductor with holes centrally located in the balls and aligned parallel with the longitudinal axis of the transmission line sewing to compression relieve the balls and improve the VSWR of the transmission line, and with seventy-degree V-grooves being located on either side of the recesses in longitudinal alignment with the coaxial transmission line, for further improving the VSWR by adding inductance to compensate for the capacitance added by the presence of the balls.

A connector for impedance-matched low capacitance connection to coaxial cable includes an electrically conductive housing having a pair of intersecting channels therein. A first channel receives the insulated conductor of a coaxial cable and the other channel seats an insulator which supports a contact element in the first channel for insulation-piercing of the insulated conductor. The housing is electrically connected to the shield of the coaxial cable and the transition through the contact element to ancillary apparatus is carried out with electrical equivalence to the coaxial cable environment.
