Abstract
Abstract An electrical connector incorporating a male shell having a cylindrical metal body in which is lodged at least one contact of a first type, a female shell having a cylindrical metal body in which is lodged at least one contact of a second type which is to cooperate with the contact of the first type, an assembly nut (3) freely rotatable mounted on one of the shells and becoming fixed by rotation on the outer surface of the other shell and a means to prevent the accidental uncoupling of the assembly nut comprising a radial set of teeth (7) carried either by the assembly nut or by the shell carrying the nut and directed toward the other of the two elements and by a means cooperating with the set of teeth and fixed on the other element. The means cooperating with the set of teeth comprises at least one blade (41) fixed so as to form two lever arms (41', 41"), each lever arm bearing a tooth (42', 42") adapted to cooperate with the set of teeth, the spread between the two teeth being chosen so that only one of the teeth will be in engagement at any one time.

Claim 1
Independent Claim
229 words
An electrical connector incorporating a male shell comprising a cylindrical metal body in which is lodged at least one contact of a first type, a female shell comprising a cylindrical metal body in which is lodged at least one contact of a second type which is adapted to cooperate with said contact of the first type, an assembly nut mounted to rotate on one of the shells and becoming fixed by rotation on an outer surface of the other shell, and means to prevent the accidental uncoupling of the assembly nut comprising a radial set of teeth carried either by the assembly nut or by the shell carrying the nut and extending toward the other of the two elements and by means cooperating with the set of teeth and fixed on the other element, wherein said means cooperating with the set of teeth is constituted by at least one blade fixed so as to form two lever arms, each lever arm bearing a tooth which is adapted to cooperate with the set of teeth, the spacing between the two teeth being chosen so that only one of the teeth will be in engagement at a particular time and wherein said blade is rotatably mounted on an axis parallel to the main axis of the connector against the bottom wall of the nut or on the shell carrying the nut.

An electrical connector incorporating a male shell comprising a cylindrical metal body in which is lodged at least one contact of a first type, a female shell comprising a cylindrical metal body in which is lodged at least one contact of a second type which is adapted to cooperate with said contact of the first type, an assembly nut mounted to rotate on one of the shells and becoming fixed by rotation on an outer surface of the other shell, and means to prevent the accidental uncoupling of the assembly nut comprising a radial set of teeth carried either by the assembly nut or by the shell carrying the nut and extending toward the other of the two elements and by means cooperating with the set of teeth and fixed on the other element, wherein said means cooperating with the set of teeth is constituted by at least one blade fixed so as to form two lever arms, each lever arm bearing a tooth which is adapted to cooperate with the set of teeth, the spacing between the two teeth being chosen so that only one of the teeth will be in engagement at a particular time and wherein said blade is rotatably mounted on an axis parallel to the main axis of the connector against the bottom wall of the nut or on the shell carrying the nut.
Claim 3
Dependent Claim
25 words
A connector according to claim 1, wherein said blade is mounted against the bottom wall of the nut or on the shell carrying the nut.
Claim 4
Dependent Claim
37 words
A connector according to claim 1, wherein the blade or blades are integral with a strap made of a semirigid material in a groove provided in the assembly nut or on the shell bearing the said nut.
Claim 5
Dependent Claim
19 words
A connector according to claim 3, wherein the pitch between the blades formed on a given strap is fixed.
Claim 6
Dependent Claim
35 words
A connector according to any one of claims 1, 3, 4 wherein the teeth in the set of teeth have slopes forming unequal angles relative to the radius passing through the bottom of a tooth.
Claim 7
Dependent Claim
35 words
A connector according to any one of claims 1, 3, 4 or 5 wherein the teeth of the blade have slopes forming unequal angles relative to the radius passing through the bottom of a tooth.
