Abstract

An electrical connector includes a window assembly including an electrically insulating transparent base and a plurality of electrically insulating transparent windows extending outwardly therefrom. The connector may include an electrically conducting body having spaced apart cable-receiving passageways for receiving respective insulation-free electrical cable ends therein, and with each cable-receiving passageway having a cable inlet opening and a cable end viewing opening opposite the cable inlet opening. The body may also have at least one respective fastener-receiving passageway intersecting each cable-receiving passageway. The individual windows of the window assembly are aligned with respective cable end viewing openings to provide a cover and to permit visual confirmation of proper placement of the insulation-free electrical cable end within a corresponding one of the cable-receiving passageways. The connector may further include an insulating cover on the body and defining a seal with the window assembly.

Claims (46)

1. An electrical connector for a plurality of electrical cables comprising:

an electrically conductive body having a plurality of spaced apart cable-receiving passageways for receiving respective insulation-free electrical cable ends therein, each cable-receiving passageway having a cable inlet opening and a cable end viewing opening opposite the cable inlet opening;

said electrically conductive body also having at least one respective fastener-receiving passageway intersecting each of the cable-receiving passageways;

a respective fastener in each of the fastener-receiving passageways;

a window assembly comprising an electrically insulating transparent base and a plurality of electrically insulating transparent windows extending outwardly therefrom and aligned with respective cable end viewing openings to provide a cover and to permit visual confirmation of proper placement of the insulation-free electrical cable end within a corresponding one of the cable-receiving passageways;

an insulating cover on said electrically conductive body and defining a seal with said window assembly;

wherein said cover comprises a thermoplastic elastomer (TPE); and

wherein the seal between said window assembly and said cover comprises an integrally molded bond.

2. An electrical connector according to claim 1 wherein said window assembly further comprises a plurality of ribs extending outwardly from said electrically insulating transparent base.

3. An electrical connector according to claim 2 wherein said electrically insulating transparent base has an elongate shape; and wherein each of said plurality of ribs extends transverse to said electrically insulating transparent base between adjacent ones of said electrically insulating transparent windows.

4. An electrical connector according to claim 1 wherein said window assembly comprises polypropylene.

5. An electrical connector according to claim 1 wherein said cover has an access opening therein for receiving said electrically conductive body therethrough; and wherein said window assembly closes the access opening in said cover.

6. An electrical connector according to claim 1 wherein said electrically insulating transparent base and said plurality of electrically insulating transparent windows are integrally formed as a monolithic unit.

7. An electrical connector according to claim 1 wherein said insulating cover comprises an integrally molded respective tubular cable inlet aligned with each of the cable inlet openings.

8. An electrical connector according to claim 1 wherein said insulating cover further comprises an integrally molded respective tubular fastener inlet aligned with each of the fastener-receiving passageways.

9. An electrical connector according to claim 1 wherein said electrically conductive body has a generally rectangular shape.

10. An electrical connector for a plurality of electrical cables comprising:

an electrically conductive body having a plurality of spaced apart cable-receiving passageways for receiving respective insulation-free electrical cable ends therein, each cable-receiving passageway having a cable inlet opening and a cable end viewing opening opposite the cable inlet opening;

said electrically conductive body also having at least one respective fastener-receiving passageway intersecting each of the cable-receiving passageways;

a window assembly comprising an electrically insulating transparent base and a plurality of electrically insulating transparent windows extending outwardly therefrom and integrally formed therewith as a monolithic unit, said plurality of electrically insulating transparent windows being aligned with respective cable end viewing openings to provide a cover and to permit visual confirmation of proper placement of the insulation-free electrical cable end within a corresponding one of the cable-receiving passageways;

an insulating cover on said electrically conductive body and defining a seal with said window assembly, said cover having an access opening therein for receiving said electrically conductive body therethrough and being closed by said window assembly and forming a seal therewith;

wherein said cover comprises a thermoplastic elastomer (TPE); and

wherein the seal between said window assembly and said cover comprises an integrally molded bond.

11. An electrical connector according to claim 10 wherein said window assembly further comprises a plurality of ribs extending outwardly from said electrically insulating transparent base.

12. An electrical connector according claim 11 wherein said electrically insulating transparent base has an elongate shape; and wherein each of said plurality of ribs extends transverse to said electrically insulating transparent base between adjacent ones of said electrically insulating transparent windows.

13. An electrical connector according to claim 10 wherein said window assembly comprises polypropylene.

14. An electrical connector according to claim 10 wherein said insulating cover comprises an integrally molded respective tubular cable inlet aligned with each of the cable inlet openings.

15. An electrical connector according to claim 10 wherein said insulating cover further comprises an integrally molded respective tubular fastener inlet aligned with each of the fastener-receiving passageways.

16. An electrical connector according to claim 10 wherein said electrically conductive body has a generally rectangular shape.

17. A method for making an electrical connector for a plurality of electrical cables comprising:

forming an electrically conductive body to have a plurality of spaced apart cable-receiving passageways for receiving respective insulation-free electrical cable ends therein, each cable-receiving passageway having a cable inlet opening and a cable end viewing opening opposite the cable inlet opening, and

at least one respective fastener-receiving passageway intersecting each of the cable-receiving passageways;

forming an insulating cover having an access opening therein and receiving the electrically conductive body therethrough;

forming a window assembly comprising an electrically insulating transparent base and a plurality of electrically insulating transparent windows extending outwardly therefrom; and

closing the access opening in the insulating cover with the window assembly so that the electrically insulating transparent windows are aligned with the cable end viewing openings to provide a cover and to permit visual confirmation of proper placement of the insulation-free electrical cable end within a corresponding one of the cable-receiving passageways;

wherein forming the insulating cover comprises forming the insulating cover to comprise a thermoplastic elastomer (TPE); and

wherein forming the seal between the window assembly and the cover comprises forming an integrally molded bond therebetween.

18. A method according to claim 17 further comprising forming a seal between the window assembly and the insulating cover.

19. A method according to claim 17 wherein forming the window assembly comprises forming the window assembly to comprise polypropylene.

20. A method according to claim 17 wherein the window assembly further comprises a plurality of ribs extending outwardly from the electrically insulating transparent base on the window assembly.

21. A method according to claim 20 wherein the electrically insulating transparent base has an elongate shape; and wherein each of the plurality of ribs extends transverse to the electrically insulating transparent base between adjacent ones of the electrically insulating transparent windows.

22. A method according to claim 17 wherein forming the window assembly comprises integrally molding the electrically insulating transparent base and the plurality of electrically insulating transparent windows as a monolithic unit.
