Abstract

A multiconductor cable connector includes two identical longitudinally arranged box-like housings each having connector fittings at one end to pass a multiconductor cable into the housings. Each housing has male and female multiterminal connector openings on one face thereof, and spaced from one another. Protective covers are hinged to the housings and arranged to cover the connector openings. Springs in the hinges urge the covers to close over the connector openings. The covers are arranged to open in opposite directions. Cam surfaces are formed on facing end edges of the covers so that when the two housings are fitted perpendicularly together with respective spaces between covers facing one another and then a 90° twisting motion is applied to bring opposite ends of the housings together, the cam surfaces on the covers on one housing engage the side walls of the other housing to force the covers into an open position to permit the mating connector openings to face one another and be pressed together into mating contact.

Claims

1. A method of connecting a pair of elongated mating electrical connector housings each having a first side with a male and a female contact thereon, each such contact having an associated hinged cover plate biased into a contact covering position when said pair of connectors is unmated, comprising the steps of:

placing said elongated connector housings at substantially right angles to one another;

while at right angles, bringing said connector housings into proximate contact adjacent their first sides;

while holding such connector housings in proximate contact, rotating one housing about ninety degrees relative to the other housing in the plane of contact to bring said housings into substantially parallel mating arrangement;

while rotating said housings, contacting a camming surface of each of said cover plates with the other housing to move said cover plates to an open position exposing the associated contacts; and

when said housings have been rotated into substantially parallel mating arrangement relative to one another pushing said housings together to bring said contacts into contacting engagement.

2. A multiple conductor electrical cable connector, comprising:

an elongate housing;

first and second electrical contact members on a first side of said housing and spaced longitudinally along the major axis of said housing;

first and second cover means hingedly connected to said housing so that in a closed position said cover means respectively cover said first and second electrical contact members; and

first and second cam means located respectively on the sides of said first and second cover means which face toward each other, each cam means configured so that an elongate body placed between said cover means substantially in a plane parallel to that of said elongate housing and rotated in said plane toward said cam means to contact said cam means would simultaneously move said first and second cover means to a position uncovering said electrical contact members.

3. The cable connector of claim 2 further comprising first and second biasing means to maintain said hingedly connected cover means in a closed position protectively covering said electrical contact members when said cable connector is not in use.

4. The cable connector of claim 3 wherein said biasing means are spring biasing means.

5. The cable connector of claim 2 wherein said first and second cover means are located sufficiently far apart to permit the use of a second identical cable connector as said elongate body to cam open said cover means.

6. The cable connector of claim 2 wherein said firstelectrical contact member is a female member and said second electrical contact member is a male member.

7. The cable connector of claim 2 wherein said first side of said housing is substantially flat.

8. The cable connector of claim 2 wherein said elongate housing has a rectangular shape with parallel outer surfaces.

9. The cable connector of claim 2 further comprising cable means connected with said electrical contact members and means for providing entry of said cable means into the interior of said housing.

10. The cable connector of claim 9 further comprising strain relief means in said means for providing entry of said cable means into the interior of said housing.

11. The cable connector of claim 10 wherein said strain relief means through which said cable means passes comprises a toroidal cap member having an inwardly tapered bore and an end closure member having an outwardly tapered bore, said cap member and said closure member being adapted for threaded engagement with each other.

12. An electrical connector apparatus, comprising:

a pair of elongate housings each having a first surface for mating association with the first surface of the other housing and each housing including;

first and second electrical contact members on said first surface of each housing, spaced longitudinally along the major axis of each housing and spaced for mating engagement of said electrical contact members of one housing with those of the other so that said first electrical contact member of one housing is capable of matingly engaging the second electrical contact member of the other housing;

first and second cover means hingedly connected to each of said housings so that in a closed position said cover means respectively cover said first and second electrical contact members of each housing, said first and second cover means of each housing located sufficiently far apart to permit said housings to be placed at about right angles to one another with said first surfaces proximate one another and each of said first surfaces between said pair of cover means of the other of said housings; and

first and second cam means located respectively on the sides which face toward each other of said first and second cover means of each housing, each cam means configured so that when a first housing is placed between said cover means of the other of said housings and substantially in a plane parallel to that of said other housing with said first surfaces proximate one another and is rotated in said plane, each of said housings will contact said cam means on said first and second cover means of the other of said housings and simultaneously move said first and second cover means to a position uncovering said first and second electrical contact members on each housing.

13. The connector apparatus of claim 12 wherein each housing further comprises first and second biasing means to maintain said hingedly connected cover means in a closed position protectively covering said contact members when said cable connector is not in use.

14. The connector apparatus of claim 13 wherein said biasing means are spring biasing means.

15. The connector apparatus of claim 12 wherein on each of said housings said first electrical contact member is a female member and said second electrical contact member is a male member.

16. The connector apparatus of claim 12 wherein said first side of each of said housings is substantially flat.

17. The connector apparatus of claim 12 further comprising on each housing cable means connected with said electrical contact members and means for providing entry of said cable means into the interior of each housing.

18. The connector apparatus of claim 17 further comprising on each housing strain relief means in said means for providing entry of said cable means into the interior of said housing.

19. The apparatus of claim 12 wherein when said housings are arranged at substantially right angles, the facing sides of said cover means of each housing are positioned substantially adjacent the longitudinal sides of the other of said housings.

20. The apparatus of claim 19 wherein said cam means is formed on said facing sides of said cover means and distal from the hinge sides of said cover means.

21. The apparatus of claim 20 wherein rotation of said housings in the plane of said proximate first surfaces from a position substantially at right angles to a position substantially parallel moves said cam means against the sides of the other of said housings and moves said cover means to a position uncovering said contact means.

22. The apparatus of claim 15 wherein said respective cover means associated with each of said male and female contact members on each of said housings open about their hinged connections in opposite directions.
