DEFINITION

Classification: 439/801

Screw-thread operated securing part:

(under subclass 775) Electrical connector wherein the clamping pressure is caused by the motion resulting from the relative rotation between a mating pair of male and female screw-threaded members.

SEE OR SEARCH THIS CLASS, SUBCLASS:

411+, for an electrical connector having a cutter-type contact for penetrating through a conductor sheath and which comprises a screw, a screw operated cutter, or a screw means to move a conductor against the cutter.

428+, for an electrical connector having a cutter-type contact which axially penetrates an elongated conductor and which comprises a screw or screw operated means.

431+, for an electrical connector having a cutter-type

contact which comprises a screw, a screw operated cutter, or a screw means to move a conductor against the cutter.

479, for an electrical connector attachable to an overhead conductor, which connector includes a handle operated screw to effect gripping of the overhead conductor.

727+, for an electrical connector having screw-thread operated, insulated part for securing a conductor or mating connector thereto. 758, for a metallic clamp-type connector for a storage battery terminal in which the clamp is secured to and separated from the battery post by a single screw-threaded member.

762+, for a metallic clamp-type connector for a storage battery terminal which comprises a screw-thread operated, deformable C- U-clamp.

765+, for a metallic clamp-type connector having screw-thread operated securing means and which is particularly adapted to be clamped to a storage battery terminal.
