Abstract
Abstract A connecting device for establishing stable electrical connections for interconnecting at least two conductors, this device ensuring both the conduction between the conductors and the mechanical assembly. The device comprises a terminal element having a tubular guide in which there is engaged one of the conductors an adjacent sleeve which receives the bared end of this conductor after it has been folded 180°, and a tongue of conductive material which partly penetrates the sleeves of at least two contiguous connecting terminal elements so as to achieve the electrical junction between the conductors carried by said terminal elements. The tongue comprises at least one retaining point which co-operates with a complementary cavity located in the sleeve, whereby the tongue which achieves the electrical conduction also ensures the locking of the conductors by a simple clipping in the connecting terminal elements.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
175 words
A connecting device for establishing electrical connection between at least two conductors, comprising: a. a pair of terminal elements each having a flat front face (4) for juxtapositioning with and connecting to the other terminal element, and a cylindrically-shaped longitudinal tubular guide (3) in which one of the conductors (12) is to be inserted; b. a longitudinal flat sleeve (2) adjacent each said longitudinal cylindrically-shaped guide to receive the bared end (14) of one conductor (12) after it has been folded in a hairpin turn, each sleeve (2) having at least one cavity (8) therein; and, c. a tongue (6) of conductive material which partly penetrates the sleeves (2) of said terminal elements when the faces thereof are juxtapositioned for producing the electrical junction between the conductors inserted in the two juxtapositioned terminal elements, said tongue (6) having at least two retaining points (8) which cooperate with and are complementary to said cavities (8) so that the tongue while achieving electrical connection also ensures the locking of the conductors by clipping together opposed terminal elements.
Claim 2
Dependent Claim
175 words
A connecting device for establishing electrical connection between at least two conductors, comprising: a. a pair of terminal elements each having a flat front face (4) for juxtapositioning with and connecting to the other terminal element, and a cylindrically-shaped longitudinal tubular guide (3) in which one of the conductors (12) is to be inserted; b. a longitudinal flat sleeve (2) adjacent each said longitudinal cylindrically-shaped guide to receive the bared end (14) of one conductor (12) after it has been folded in a hairpin turn, each sleeve (2) having at least one cavity (8) therein; and, c. a tongue (6) of conductive material which partly penetrates the sleeves (2) of said terminal elements when the faces thereof are juxtapositioned for producing the electrical junction between the conductors inserted in the two juxtapositioned terminal elements, said tongue (6) having at least two retaining points (8) which cooperate with and are complementary to said cavities (8) so that the tongue while achieving electrical connection also ensures the locking of the conductors by clipping together opposed terminal elements.
Claim 3
Dependent Claim
24 words
A connecting device as claimed in claim 1, wherein the two retaining points are in the form of bosses having different radii of curvature.
Claim 4
Dependent Claim
27 words
A connecting device as claimed in claim 1, wherein each sleeve of each terminal element comprises two confronting cavities, said cavities being of different dimensions or depths.
Claim 5
Dependent Claim
74 words
A connecting device as claimed in claim 1, wherein the inner end of each tubular guide of each terminal element has a polygonal-section frustoconical portion in the vicinity of the fold region of one of the conductors so as to prevent them from moving axially forwardly, the rearward displacement being rendered impossible by at least one lug projecting inside each tubular guide and by the hairpin fold of the bared end of each conductor.
Claim 6
Dependent Claim
30 words
A connecting device as claimed in claim 1, wherein the terminal elements have on their rear end faces cavities for receiving assembling means for uniting a series of terminal elements.
Claim 7
Dependent Claim
54 words
A connecting device as claimed in claim 1, wherein each sleeve is at least partly longitudinally split so as to define two lateral flanges which are in facing relation and have on the front face of each terminal element openings the depth of which is substantially equal to the length of half the tongue.
Claim 8
Dependent Claim
31 words
A connecting device as claimed in claim 6, wherein the tongue is cut from an electrically conductive sheet material and is planar in shape and has a plurality of connecting tabs.
