An attachment arrangement is carried by a bushing assembly of a high voltage electrical distribution system and facilitates attachment and securing of the bushing assembly to an electrical connector and subsequent attachment and securing of the electrical connector to a terminal of an electrical apparatus, the attachment arrangement including sequentially operated threaded elements having minimum torque responsive devices for assuring that the sequence of operation of the threaded elements will secure the bushing appropriately to the electrical connector and then will secure the electrical connector to the terminal.

An attachment arrangement for facilitating attaching and securing a bushing assembly within an electrical connector of a high voltage electrical distribution system, the electrical connector having an axially extending recess including a tapered portion, a terminal contact affixed to a conductor of a high voltage cable and including a portion extending into the recess, the terminal contact having a threaded aperture placed within the recess and aligned axially with the tapered portion of the recess, the bushing assembly including an axially extending tapered body portion complementary to the tapered portion of the recess in the electrical connector such that the complementary tapered portion will be engaged in an appropriate interference fit, the tapered body portion terminating at a terminal end, said attachment arrangement comprising: a tubular member extending in an axial direction within the bushing assembly adjacent the terminal end thereof and having an axially extending internal thread therein; a coupling member coupled with the tubular member and projecting axially beyond the terminal end of the tapered body portion of the bushing assembly, the coupling member including a first external thread at least a portion of which is spaced axially away from the tubular member for engaging the threaded aperture of the terminal contact, and a second external thread engaged with the internal thread of the tubular member; wrenching means associated with the tubular member for enabling rotation of the tubular member about the axial direction, the tubular member being so affixed within the bushing assembly as to assure concomitant rotation of the bushing assembly in response to said rotation of the tubular member; minimum torque responsive means for precluding relative movement between the tubular member and the coupling member below a predetermined torque exerted by the tubular member upon the coupling member; and stop means located such that upon insertion of the bushing assembly into the recess of the electrical connector and initial rotation of the bushing assembly, the coupling member will rotate with the bushing assembly, and the first external thread of the coupling member will be engaged within the threaded aperture of the terminal contact prior to the engagement of the complementary tapered portions in said interference fit, and continued rotation of the bushing member, as enabled by the wrenching means, will exceed the predetermined torque of the minimum torque means to further engage the second thread within the internal thread of the tubular member until the complementary tapered portions are engaged fully in said interference fit and proper electrical contact is made between the tubular member and the terminal contact.
