Abstract
Abstract This disclosure relates to an electrical connector device having terminal-contact members with terminal portions retained in cavities in an insulator body, each terminal portion having binding plates angularly disposed with respect to the axis of the device. Angularly disposed wire entry openings are provided in the insulator body to direct wire lead ends to the binding plate wiring areas. The terminal-contact members and the insulator body are formed with keying means to provide noninterchangeability of these members in the cavities, and a protective cover is secured to the insulator body with a labyrinthian seal located between the insulator body and the protective cover to protect the wiring areas from foreign matter.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
341 words
A back-wired electrical connector body comprising: an insulator body including a terminal retainer element and a contact holder element secured thereto, said contact holder element having spring contact receiving chambers; plural terminal-contact members carried by said insulator body; each of said members having a terminal portion disposed in said insulator body and isolated from every other of said terminal portions; each of said terminal portions including axially extending mounting means and a binding plate which is angularly disposed with respect to said mounting means and the axis of the device; one of said terminal-contact members being a grounding member having contact portions and the others being line members having spring contact portions; said grounding member having keying means in the form of wider mounting means than said line terminal mounting means; said terminal retainer element including means to receive said wider mounting means; each of said members including keying feet extending laterally outwardly from the spring contact portions thereof, the keying feet located on said line members being aligned and the keying feet located on said grounding member being offset with respect to one another; one of said spring contact receiving chambers being a grounding contact receiving chamber and the others being line contact receiving chambers, said chambers including seats for receiving the respective keying feet so that the grounding spring contact portions may not be seated in any of said line contact receiving chambers and the line spring contact portions cannot be seated in said grounding contact receiving chamber; terminal clamping screws rotatably carried by said binding plates; clamping nuts threadedly engaged with said screws and nonrotatably mounted in said insulator body; radial openings formed in said insulator body to provide access to the heads of said terminal clamping screws; wire entry openings formed in said insulator body providing access for wire lead ends to said binding plates, the axes of said wire entry openings being angularly Disposed with respect to the axis of the device; and a protective cover secured to said insulator body to enclose said terminal portions.
Claim 2
Dependent Claim
341 words
A back-wired electrical connector body comprising: an insulator body including a terminal retainer element and a contact holder element secured thereto, said contact holder element having spring contact receiving chambers; plural terminal-contact members carried by said insulator body; each of said members having a terminal portion disposed in said insulator body and isolated from every other of said terminal portions; each of said terminal portions including axially extending mounting means and a binding plate which is angularly disposed with respect to said mounting means and the axis of the device; one of said terminal-contact members being a grounding member having contact portions and the others being line members having spring contact portions; said grounding member having keying means in the form of wider mounting means than said line terminal mounting means; said terminal retainer element including means to receive said wider mounting means; each of said members including keying feet extending laterally outwardly from the spring contact portions thereof, the keying feet located on said line members being aligned and the keying feet located on said grounding member being offset with respect to one another; one of said spring contact receiving chambers being a grounding contact receiving chamber and the others being line contact receiving chambers, said chambers including seats for receiving the respective keying feet so that the grounding spring contact portions may not be seated in any of said line contact receiving chambers and the line spring contact portions cannot be seated in said grounding contact receiving chamber; terminal clamping screws rotatably carried by said binding plates; clamping nuts threadedly engaged with said screws and nonrotatably mounted in said insulator body; radial openings formed in said insulator body to provide access to the heads of said terminal clamping screws; wire entry openings formed in said insulator body providing access for wire lead ends to said binding plates, the axes of said wire entry openings being angularly Disposed with respect to the axis of the device; and a protective cover secured to said insulator body to enclose said terminal portions.
Claim 3
Dependent Claim
181 words
a back-wired electrical connector device comprising: an insulator body; plural terminal-contact members carried by said insulator body; each of said members having a terminal portion disposed in said insulator body and isolated from every other of said terminal portions; each of said terminal portions including axially extending mounting means and a binding plate which is angularly disposed with respect to said mounting means and the axis of the device; terminal clamping screws rotatably carried by said binding plates; clamping nuts threadedly engaged with said screws and nonrotatably mounted in said insulator body; each of said clamping screws being eccentrically mounted in its associated clamping nut so as to provide a larger wiring land; radial openings formed in said insulator body to provide access to the heads of said terminal clamping screws; wire entry openings formed in said insulator body providing access for wire lead ends to said binding plates, the axes of said wire entry openings being angularly disposed with respect to the axis of the device; and a protective cover secured to said insulator body to enclose said terminal portions.
Claim 4
Dependent Claim
181 words
a back-wired electrical connector device comprising: an insulator body; plural terminal-contact members carried by said insulator body; each of said members having a terminal portion disposed in said insulator body and isolated from every other of said terminal portions; each of said terminal portions including axially extending mounting means and a binding plate which is angularly disposed with respect to said mounting means and the axis of the device; terminal clamping screws rotatably carried by said binding plates; clamping nuts threadedly engaged with said screws and nonrotatably mounted in said insulator body; each of said clamping screws being eccentrically mounted in its associated clamping nut so as to provide a larger wiring land; radial openings formed in said insulator body to provide access to the heads of said terminal clamping screws; wire entry openings formed in said insulator body providing access for wire lead ends to said binding plates, the axes of said wire entry openings being angularly disposed with respect to the axis of the device; and a protective cover secured to said insulator body to enclose said terminal portions.
Claim 5
Dependent Claim
21 words
The electrical connector device defined in claim 2 wherein said clamping screws are positioned substantially tangent to said wire entry openings.
