Abstract
Abstract Disclosed is a ring terminal connector which includes a pair of like circular, substantially flat apertured terminals. Each terminal has a raised bump or nib on its upper surface and a nib opening on its upper surface such that the pair of terminals may be interlocked by fixing the raised nib of each terminal in the nib opening of the other terminal. The terminals also each have a pair of inwardly directed slotted flanges and an elongated opening or groove to properly orient one terminal with respect to the other. One of the terminals may be turned over and engaged with the other terminal such that by rotating one relative to the other, the terminals may be interlocked. Further, the terminals each have an integral outwardly directed crimping arm to receive wires and maintain a positive connection between the connector and the wires and/or the bolt to which the connector is attached. The nib, elongated opening, nib opening and slotted flanges are circumferentially located such that the crimping arms do not interfere with each other when the terminals are interlocked.

Total Claims: 8
Claim 1
Independent Claim
162 words
A pair of identical terminals, each said terminal having a substantially flat circular structure about an aperture and fingers for attachment to an electrical wire, each said terminal comprising: a raised nib on said circular structure; an elongated groove in said circular structure; an opening in said circular structure, said nib, groove and opening being spaced from one another about said circular structure; a pair of flanges, each said flange forming a slot in said opening adjacent said circular structure; said nib, groove, opening and flanges being configured such that upon positioning one terminal coaxially adjacent the other with a nib of said one terminal in said groove of the other terminal and then rotating said one terminal relative to the other, said nib sequentially traverses said groove and the space on said circular structure between said groove and said opening and then positions in said opening while said flanges of said one terminal interlock with said slots of said other terminal.
Claim 2
Dependent Claim
162 words
A pair of identical terminals, each said terminal having a substantially flat circular structure about an aperture and fingers for attachment to an electrical wire, each said terminal comprising: a raised nib on said circular structure; an elongated groove in said circular structure; an opening in said circular structure, said nib, groove and opening being spaced from one another about said circular structure; a pair of flanges, each said flange forming a slot in said opening adjacent said circular structure; said nib, groove, opening and flanges being configured such that upon positioning one terminal coaxially adjacent the other with a nib of said one terminal in said groove of the other terminal and then rotating said one terminal relative to the other, said nib sequentially traverses said groove and the space on said circular structure between said groove and said opening and then positions in said opening while said flanges of said one terminal interlock with said slots of said other terminal.
Claim 3
Dependent Claim
201 words
An interlocking electrical terminal connector comprising: a pair of circular, substantially flat apertured terminals each adapted to be secured to the end of an electrical wire, said terminals being of identical configuration and each having a first and second surface; each of said terminals having a raised nib on said first surface; each of said terminals having an elongated opening; each of said terminals having an opening for receiving said nib; and each of said terminals having a pair of inwardly directed flanges having slots sized to receive each other's flanges when one terminal is turned over and its nib is placed in the elongated opening of said other terminal, and when at least one of said terminals is then rotated relative to the other, the raised nib of said one terminal travels in the opening of said other terminal until the slotted flanges of said terminals engage such that with continued rotation, the raised nib is no longer located in said opening, the terminals remain engaged and the raised nib of said one terminal enters into the nib opening of said other terminal and the raised nib of said other terminal enters into the nib opening of said one terminal.
Claim 4
