A female coaxial cable electrical connector includes an electrically conductive barrel or shell enclosing a contact carrier assembly. The contact carrier assembly consists of a cap member enclosing a subassembly that includes an elastomeric sleeve or tubing compressively but yieldably mounted over the contact receiving arms of a base member with an electrical contact secured between opposing ones of the two contact receiving arms. The electrical contact is formed from electrically conductive material, and includes two opposing half-sections that are mounted between the contact receiving arms of the base, and have side wing portions contacting one another, with opposing longitudinal semicircular grooves of the half-sections of the contact together forming a circular pathway for receiving a male electrical pin or the center conductor of a coaxial cable. When such a pin or center conductor is inserted into the electrical contact, the elastomeric sleeve initially yields on inward pressure to permit insertion of the pin, while maintaining sufficient inward pressure to force the semicircular grooves of the electrical contact to mechanically contact and surround the circumference of the male pin or center conductor, for substantially the full length of its insertion, thereby insuring a low resistance electrical contact therebetween.

A ground block connector is provided by forming a slot in a protrusion of a housing for an electrical device. A compression bolt is screwed into a threaded hole in the protrusion into the slot, for captively retaining a U-shaped compression electrical contact in the slot, whereby movement of the screw in one direction moves the contact toward the bottom of the slot, for compressibly retaining an end of a ground wire between the bottom of the contact and bottom of the slot.

Ground block connector

A tape transport apparatus for recording tape having a rotationally driven tape drive capstan for advancing the tape and a pinch roller for firmly engaging the tape with the tape drive capstan includes a rapid tape advancement feature. Clutch devices selectively couple rotational driving force to the tape drive capstan from a first normal playing rate motor devices or a second high speed advancement motor devices. The clutch devices are centrifugal force-actuated and of a ratchet-like nature. A rotating element connected to the tape drive capstan includes a code, and a sensor which senses the code and derives signals indicative of each revolution of the tape drive capstan. The signals are electrically processed and an accurate measurement of the extent of tape advancement is obtained and displayed.
