Abstract
Abstract The electrical connections between the two sections of the connector are obtained through the use of coupling elements carried by an insulating disk disposed in front of the ends of the cables of the fixed section, locked inside the body of the fixed section, displaceable axially inside of said fixed section and having no electrical contact with said ends of the cables when the two sections of the connector are disconnected.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
256 words
An electric connector comprising, in combination, a fixed section, a jacket inside said fixed section a cable plug carried by said jacket, a removable section, an insulating disk displaceable axially inside of said fixed section, electrical connecting elements in said disk, a tubular sleeve capable of sliding on said jacket and supporting said disk, a flange on said jacket, a spring for acting on said flange in order to hold said disk apart from the end of the cable plug of said fixed section when said sections are disconnected, a skirt in said fixed section encircling said displaceable sleeve bearing said disk, a shoulder at the rear extremity of said skirt serving as a stop for said flange, radial holes on said skirt, balls positioned in said holes, a peripheral groove on said sleeve which said balls can partly enter when said sections are disconnected, a sliding lock ring encircling said skirt, a second spring pushing said ring towards the exterior of said fixed section and pressing it against a shoulder on said fixed section, another skirt extending outwardly of said fixed section and situated on said locking ring and having an inner diameter which is greater than the outer diameter of said locking ring, a second cable plug carried by said removable section, means on said removable section for unlocking said disk when said sections are connected, and means for arming the unlocking device of said removable section, and to actuate the unlocking device on said removable section for disconnecting it from said fixed section.
Claim 2
Dependent Claim
256 words
An electric connector comprising, in combination, a fixed section, a jacket inside said fixed section a cable plug carried by said jacket, a removable section, an insulating disk displaceable axially inside of said fixed section, electrical connecting elements in said disk, a tubular sleeve capable of sliding on said jacket and supporting said disk, a flange on said jacket, a spring for acting on said flange in order to hold said disk apart from the end of the cable plug of said fixed section when said sections are disconnected, a skirt in said fixed section encircling said displaceable sleeve bearing said disk, a shoulder at the rear extremity of said skirt serving as a stop for said flange, radial holes on said skirt, balls positioned in said holes, a peripheral groove on said sleeve which said balls can partly enter when said sections are disconnected, a sliding lock ring encircling said skirt, a second spring pushing said ring towards the exterior of said fixed section and pressing it against a shoulder on said fixed section, another skirt extending outwardly of said fixed section and situated on said locking ring and having an inner diameter which is greater than the outer diameter of said locking ring, a second cable plug carried by said removable section, means on said removable section for unlocking said disk when said sections are connected, and means for arming the unlocking device of said removable section, and to actuate the unlocking device on said removable section for disconnecting it from said fixed section.
Claim 3
Dependent Claim
264 words
An electric connector comprising, in combination, a fixed section, a jacket inside said fixed section, a cable plug carried by said jacket, a removable section, a second cable plug carried by said removable section, an insulating disk axially displaceable inside said fixed section, electric connecting elements in said disk, a tubular sleeve capable of sliding on said jacket and supporting said disk, a flange on said jacket, a spring acting on said flange in order to hold said disk apart from the cable plug of said fixed section when said two section are disconnected, a skirt on said fixed section encircling said disk-bearing displaceable sleeve, a shoulder on the rear extremity of said skirt serving as a stop for said flange on the disk-bearing sleeve, radial holes on said skirt, balls in said holes, a peripheral groove on said sleeve which said balls can partly enter when said sections are disconnected, a sliding lock ring encircling said skirt, a second spring pushing said ring toward the exterior of said fixed section, pressing it against a shoulder in said fixed section and in such a manner that said ring holds said balls in their groove, another skirt extends outwardly on said lock ring and the inner diameter of the same is greater than that of said ring, a second jacket capable of sliding in said removable section and resting against said fixed section when said sections are connected, and a tip at the front end of said second jacket for pushing back said locking ring of said displaceable disk upon the connection of said sections.
