Abstract: A connector for an optical fiber cable includes a strain relief structure provided with a first annular retention member (16) having a first bearing surface (51c) cooperating with a jacket retention portion (63) of an annular retention sleeve (18) for retaining the outer jacket (33) of the cable (25), and a second bearing surface (44) of an annular retention member (17) cooperating with a strengthening layer retention portion (61) of an annular retention sleeve (18) for retaining the inner strengthening layer (33) of the cable.

Abstract: A polishing bushing for polishing the end face of an optical fiber supported within a rigid sleeve includes a bushing base (31, 131) having a front surface (36, 136). The rigid sleeve (21, 21a) normally protrudes from beyond the front surface (36, 136) to permit the end face (14, 14a) of the optical fiber (12, 12a) carried therein to be polished. The bushing includes resilient portion (34) for permitting the rigid sleeve (21, 21a) to move longitudinally in passageway (38) to limit the force applied to the end face (14, 14a) of the fiber (12, 12a) by the polishing medium. The front surface (36, 136) of the bushing base (31, 131) is of spherical shape to produce a polished fiber end face (14) which is convex and which protrudes from the rigid sleeve (21) by less than about one micron, or is of flat shape to consistently produce a polished end face (14a) which is recessed within the sleeve ( 21a) by less than about one micron.

Abstract: An adhesiveless connector for optical fiber cables is formed by a body having a profiled through passage of inwardly directed threads and a narrow fiber passing bore at the opposite end, a fiber clamp received in the body and having its axial bore, and a clamp insert having exterior threads engaging with the threads of the body and a plurality of cantilever arms which engage the body and fiber clamp to securely grip the fiber and buffer of an optical cable passing therethrough. The termination also includes a cylindrical eyelet which can be used to crimp the cable strength members to the connector.

Abstract: An electrical and fiber optic connector assembly terminates the electrical conductors and fiber optic transmission members of a cable so that the electrical conductors are electrically connected to electrical terminals latchably mounted in a housing member and for electrical connection to electrical paths of a circuit board and the fiber optic transmission members are optically connected to transmitting and sensing photoelectric devices which are mounted in the housing member and also electrically connected to electrical terminals latchably mounted in the housing member for electrical connection to electrical paths of the circuit board.

Abstract: An electrical connector for flat transmission cable comprises a body member having terminal-receiving passageways and conductor-receiving passageways. Electrical terminals are disposed in the terminal-receiving passageways for terminating electrical conductors of a flat transmission cable which are disposed in respective conductor-receiving passageways. Cover members are secured onto the body member and they include strain relief members engaging the flat transmission cable and the respective electrical conductors. According to another aspect of the present invention, the cover members include projections that are disposed on each side of the conductor-receiving sections of the electrical terminals to prevent the electrical conductors from disconnecting from the conductor-receiving sections.

Abstract: An electrical connector is disclosed of a multi-piece configuration, comprising a connector block having a row of contact-receiving cavities in oppositely-facing surfaces thereof, and a pair of hermaphroditic connector covers for intended assembly over the oppositely-facing block surfaces. The block is provided with parallel rows of receptacle passageways in a frontal face thereof, each accessing a respective cavity. The covers each are provided with a plurality of forwardly-projecting stud projections, serially spaced across a forward end thereof. The projections are inserted into respective receptacle passageways, and cooperate with interior surfaces defining the passageways to define a funnel-shaped profile for guided receipt of terminal pins therethrough.

Abstract: An electrical connector assembly is disclosed for terminating a flat transmission cable. The assembly comprises a body having forwardly disposed terminal members seated in oppositely facing surfaces thereof for terminating the cable conductors, and a pair of hermaphroditic connector covers for intended assembly over the oppositely facing body surfaces. Each cover is configured having a transverse tapered ridge extending thereacross at a rearward end thereof, and a transverse recess continuing thereacross in colinear alignment with the ridge. The ridge and recess of one cover are located in compliment to the recess and ridge of the opposite cover, and upon positioning the flat cable between rearward portions of the covers and swinging the covers into a mutually parallel relationship, the connector cover ridges deform a cable portion therebetween to adopt the profile of the intercover space and thereby effectuate secure clamping engagement between the covers and the flat transmission cable.

Abstract: The disclosure relates to an assembly of electrical contacts with a center conductor and a ground conductor on a coaxial cable, the assembly including further a one-piece housing having two parts hinged to each other for closure together, thereby terminating the conductors to the contacts and providing an enclosure for the terminated conductors. The contacts protrude from the housing for pluggable connection into apertures of a printed circuit board.

Abstract: The combination of a flat multi-wire cable and a connector means for terminating such cable wherein a portion of the cable near the end thereof is stripped of insulation with a short section of unstripped cable between the stripped portion and the end of the cable. Wires designated as signal wires in the stripped portion are severed near the short insulated section thereof after which the short insulated section and the remaining unsevered wires, designated as ground wires, are folded back over the undisturbed insulated cable, thereby leaving the severed signal wires extending outward and over two parallel rows of first slotted contacts secured in a first housing section. By an appropriate tool the extended signal wires are simultaneously inserted in said first slots in parallel manner and without solder. A second housing section is installed over the first housing section to retain the first contacts in said first slots.
