Abstract
Abstract A plug-and-socket connector for connecting two lengths e.g. two lengths of an electric cable, particularly, under adverse operation conditions (i.e. when the connection is acted upon by dust, mud, water, vibrations, jogging, impacts, etc.), comprising a male plug member, a female receptacle member and a coupling and locking assembly mounted, preferably, on the body of said male plug member, this coupling and locking assembly including an external nut and two rings received internally of said external nut and extending about the body of the male plug member; the herein disclosed plug-and-socket connector features a dependable and comparatively simple structure of its coupling and locking assembly; the main parts of this plug-and-socket connector may be made of a strong plastic material.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
181 words
A plug-and-socket connector including a female receptacle member; a male plug member, each of said members including a body, and a coupling and locking assembly mounted movably on one of said bodies and comprising a sleeve nut including a circular shoulder and longitudinal lugs positioned on the inside thereof and multiple thread turns extending into connection with a helical thread included by the other of said bodies for locking said female receptacle member and said male plug member in a coupled position; a first ring located inside said sleeve nut and surrounding said body of the male plug member, said ring being movably mounted for limited axial biasing relative to said sleeve nut and for rotation therewith about said body of the male plug member; a second ring located inside said sleeve nut and surrounding said body of the male plug member, said second ring being immovably mounted on said body of the male plug member, and spring means for axially biasing said first ring in the direction of said second ring mounted on said body of the male plug member.
Claim 2
Dependent Claim
181 words
A plug-and-socket connector including a female receptacle member; a male plug member, each of said members including a body, and a coupling and locking assembly mounted movably on one of said bodies and comprising a sleeve nut including a circular shoulder and longitudinal lugs positioned on the inside thereof and multiple thread turns extending into connection with a helical thread included by the other of said bodies for locking said female receptacle member and said male plug member in a coupled position; a first ring located inside said sleeve nut and surrounding said body of the male plug member, said ring being movably mounted for limited axial biasing relative to said sleeve nut and for rotation therewith about said body of the male plug member; a second ring located inside said sleeve nut and surrounding said body of the male plug member, said second ring being immovably mounted on said body of the male plug member, and spring means for axially biasing said first ring in the direction of said second ring mounted on said body of the male plug member.
Claim 3
Dependent Claim
66 words
A plug-and-socket connector according to claim 1, wherein said first ring is provided with recesses on the end side adjacent said second ring, said second ring including projections corresponding to said recesses on the end side adjacent to said first ring, said recesses receiving said projections when said sleeve nut is fully screwed in or out with respect to said body of the male plug member.
Claim 4
Dependent Claim
174 words
A plug-and-socket connector including a female receptacle member; a male plug member, each of said members including a body, and a coupling and locking assembly mounted movably on the body of said male plug member and comprising a sleeve nut including a circular shoulder and longitudinal lugs positioned on the insider thereof and multiple thread turns extending into connection with a helical thread included on said body of the female receptacle member for locking said female receptacle mEmber and said male plug member in a coupled position; a first ring and a second ring located inside said sleeve nut and surrounding said body of the male plug member, and spring means for axially biasing said first ring in the direction of said second ring, said first ring having longitudinal projections for interconnection with said sleeve nut, said projections engaging respective longitudinal recesses provided in said circular shoulder inside said sleeve nut and forming sockets for the accommodation of said spring means for causing reciprocation of said first ring with respect to said sleeve nut.
Claim 5
Dependent Claim
174 words
A plug-and-socket connector including a female receptacle member; a male plug member, each of said members including a body, and a coupling and locking assembly mounted movably on the body of said male plug member and comprising a sleeve nut including a circular shoulder and longitudinal lugs positioned on the insider thereof and multiple thread turns extending into connection with a helical thread included on said body of the female receptacle member for locking said female receptacle mEmber and said male plug member in a coupled position; a first ring and a second ring located inside said sleeve nut and surrounding said body of the male plug member, and spring means for axially biasing said first ring in the direction of said second ring, said first ring having longitudinal projections for interconnection with said sleeve nut, said projections engaging respective longitudinal recesses provided in said circular shoulder inside said sleeve nut and forming sockets for the accommodation of said spring means for causing reciprocation of said first ring with respect to said sleeve nut.
Claim 6
Dependent Claim
173 words
A plug-and-socket connector including a female receptacle member; a male plug member, each of said members including a body, and a coupling and locking assembly mounted movably on the body of said male plug member and comprising a sleeve nut including a circular shoulder and longitudinal lugs positioned on the inside thereof and multiple thread turns extending into connection with a helical thread included on the body of said female receptacle member for locking said female receptacle member and said male plug member in a coupled position; spring means; a first ring and a second ring located inside said sleeve nut and surrounding the body of said male plug member, said body including radial lugs for securely fixing said second ring, and holding said coupling and locking assembly on the body of said male plug member; said second ring being provided with recesses on its end side, corresponding to said radial lugs on said body of the male plug member, said lugs engaging said recesses on said end side of the second ring.
