Abstract
Abstract The invention relates to a connection device which can be used to make connections, either between a wire and a terminal, or between two wires, said device being composed of a dielectric pressed part bearing a guide allowing the nesting of the end of one of the two wires to be connected to a terminal or to another wire, said guide being fitted with a parallel sleeve, the cross section of which is identical to that of the plug or the pin secured to the end of the other wire to be connected with, in such way that the bare end of the wire inserted into the guide of the device will be allowed to be folded over at 180* so as to get housed in its sleeve, the plug or terminal being then inserted in said sleeve in such way as to come in contact with the bare wires, thus providing the electrical connection between the two wires.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
174 words
A connection device for electrical installation, for connecting a stranded conductive wire to a conductive male terminal member, comprising: an elongated tubular guide of insulator material, having a wire entrance end for receiving a conductive wire and having a connection end, said guide being open at both ends; a sleeve, formed integrally with said guide and extending from said connection end of said guide back parallel to said guide; an end wall, between said guide and said sleeve at said connection end of said guide, over which a bared end segment of a stranded conductive wire extending through said guide is reverse bent back into said sleeve through an angle of about 180*; and a male terminal member, having an external configuration substantially complementary to the internal configuration of said sleeve, fitting axially into said sleeve, for jamming against a substantial length of the portion of said conductive wire which extends into said sleeve to complete a large surface electrical connection thereto and simultaneously lock said conductive wire into said sleeve and said guide.
Claim 2
Dependent Claim
174 words
A connection device for electrical installation, for connecting a stranded conductive wire to a conductive male terminal member, comprising: an elongated tubular guide of insulator material, having a wire entrance end for receiving a conductive wire and having a connection end, said guide being open at both ends; a sleeve, formed integrally with said guide and extending from said connection end of said guide back parallel to said guide; an end wall, between said guide and said sleeve at said connection end of said guide, over which a bared end segment of a stranded conductive wire extending through said guide is reverse bent back into said sleeve through an angle of about 180*; and a male terminal member, having an external configuration substantially complementary to the internal configuration of said sleeve, fitting axially into said sleeve, for jamming against a substantial length of the portion of said conductive wire which extends into said sleeve to complete a large surface electrical connection thereto and simultaneously lock said conductive wire into said sleeve and said guide.
Claim 3
Dependent Claim
45 words
A connection device according to claim 1 in which said end wall intermediate said guide and said sleeve is recessed, at said connection end of said guide, so that the entire bared length of said conductive wire is encompassed in said guide and said sleeve.
Claim 4
Dependent Claim
49 words
A connection device according to claim 1 in which said male terminal member is a substantially flat conductive plug and in which said sleeve is of rectangular internal configuration and is slotted throughout its length to afford two internal grooves for receiving the side edges of said flat plug.
Claim 5
Dependent Claim
54 words
A connection device for electrical installation according to claim 1 in which said male terminal member is a conductive plug of cylindrical cross-sectional configuration and in which said sleeve is of cylindrical cross-sectional configuration and is slotted throughout its length, said sleeve having an internal bore slightly larger than that of the cylindrical plug.
Claim 6
Dependent Claim
39 words
A connection device for electrical installation according to claim 1 in which said guide and said sleeve, at the connection end of said guide, include a stiffening rim formed integrally with and encompassing both said guide and said sleeve.
Claim 7
Dependent Claim
86 words
A connection device for electrical installation, according to claim 1, in which said male terminal member comprises an insulator plug having a stranded electrically conductive wire extending axially therethrough and bent over the free end of the plug at an angle of approximately 180* onto a relatively flat contaCt surface, and in which the internal portion of said sleeve includes a complementary contact surface for jamming the two strand conductors against each other in interleaved fashion upon insertion of said male terminal member into said sleeve.
Claim 8
Dependent Claim
64 words
A connection device for electrical installation according to claim 1, in which said sleeve includes a longitudinally extending slot along the side of the sleeve opposite said guide, and further comprising a flexible shutter, formed integrally with said sleeve at one side of said slot and engageable with a shoulder along the other side of said slot to close said slot in said sleeve.
Claim 9
Dependent Claim
55 words
A connection device for electrical installation, according to claim 1, in which said sleeve includes a longitudinal slot along the side thereof opposite said guide, and further comprising a hinged shutter formed integrally with said sleeve at one side of said slot and fitting over the opposite side of said slot to close said slot.
Claim 10
Dependent Claim
46 words
A connection device for electrical installation according to claim 1, in which said sleeve includes a longitudinal slot along the side thereof opposite said guide, and further comprising a sliding cover for said slot, secured to one of said guide and said sleeve by a cord.
