Insulating Tube, Sleeve, Or Cap Concentrically Surrounding Part Of Connector Patents (Class 439/750)
  • Patent number: 4969845
    Abstract: An electric terminal connector comprises a generally tubular metal part adapted to fit over the previously bared end of the conductive core of an insulated electric conductor. An insulative sleeve has a front portion adapted to be engaged with this metal part and a rear portion larger than the front portion adapted to fit over the corresponding end of the insulation of the electric conductor. The insulative sleeve comprises a transverse shoulder on its inside. The rear portion of the metal part is straight and its end is adapted to bear on this transverse shoulder. There is at least locally between the metal part and the insulative sleeve a film of adhesive which fastens them together. In line with at least the transverse shoulder the internal surface of the insulative sleeve has a diameter at most equal to that of the inside surface of the metal part.

  • Patent number: 4902252
    Abstract: A high voltage electrical connector for quickly connecting two stripped back electrical conductors including a plastic enclosure, a tubular glass insulator in the enclosure, a metal liner in the glass insulator, and first and second metal connectors telescopically positioned inside of the liner. Each of the connectors includes a longitudinal opening in the middle, and a longitudinal channel on the outside for receiving a bent back stripped electrical conductor. The liner includes first and second inwardly biased electrical contacts engaging the conductors in the longitudinal channels. Rotational alignment between the connectors and the liner align the biased electrical contacts with the longitudinal channels.

  • Patent number: 4891022
    Abstract: A data connector is disclosed herein which includes a plurality of terminals situated in an insulative housing, and the housing is surrounded by shielding members to form a shielded subassembly, the shielded subassembly finally being inserted within a premolded one piece boot to form a data connector which is interconnectable to shielded data cable. The data connector of the instant invention can be field assembled and installed and is intermatable with similar data connectors having T-bars and T-slots without the complexity thereof. Alternatively, the data connector of the instant invention is interconnectable with a communications outlet locally mounted which houses similar terminals electrically interconnected to like shielded data cable.

  • Patent number: 4867698
    Abstract: A coaxial electrical connector for connecting an antenna to a walkie talkie radio or the like includes a center contact member (21) for electrically connecting the antenna (12) to the radio (10), and a collar (23) having bayonet coupling structure (67) for mechanically coupling the connector to the outer contact (71) of a complementary coaxial connector (50) in the radio (10) without electrically connecting the connector to the outer contact (71). Because the antenna does not require coaxial electrical connection to the radio, the outer contact is eliminated from the coaxial connector of the present invention and replaced in support function by a semirigid, dielectric shell (22) which both electrically insulates the center contact member (21) and provides mechanical support to resist stresses caused by loads applied to the antenna.

  • Patent number: 4839470
    Abstract: This invention relates to a submersible electrical cable splice, and the method of making the same. It employs a housing sleeve of an elastomeric material which is hollowed out to include a central cavity connected at each of the ends by bores which are of slightly smaller diameter than the cables which are to be connected. In the process of making the splice, one end of the housing sleeve is lubricated, and one of the cables is pushed clear through and out the other end of the housing, where it is joined to the other cable end in abutting relation in a metal crimp connector. The joined cables are then pulled in the opposite direction back through the bore of the housing sleeve, until the crimping connector seats in the central cavity, which is of slightly smaller diameter than the crimping connector, squeezing out the air. It should be understood that a pocket or void or space is to be eliminated or reduced to insignificant amounts.

  • Patent number: 4740170
    Abstract: A removable adaptor sleeve for connecting an electrode lead having a low profile plug to a pulse generator having a high profile socket. The adaptor sleeve fits over the plug end of the electrode lead so as to provide a high profile plug configuration. The sleeve has a side wall which includes axial grooves terminating at the apex of corresponding V-shaped notches. The notches and axial grooves allow the adaptor sleeve to be torn away so as to expose for use the low profile plug end of the electrode lead, as desired.
