Abstract
Abstract The present invention relates to a bent terminal for electrical connection, which comprises an arm for crimping, an arm for connection and a joining portion defining an envelope of general toric form; this toric portion may be constituted by a semi-toric half-shell and by a complementary portion, affixed or connected thereto, cooperating with said half-shell to constitute the envelope. The invention is more particularly applicable to ignition wiring systems in internal combustion engines with controlled ignition.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
186 words
A bent terminal for electrical connection comprising an arm for crimping and for connecting electrically with a conductor, a substantially tubular arm elastically deformable radially for connecting with a complementary terminal and a bent portion of fixed shape joining said arms, the bent portion comprising a curved segment defining an envelope of generally toric form, the envelope having a cross-section substantially equal to that of the tubular arm; said envelope having a radius of curvature, taken at the level of the inner generatrix for the toric form, of the order of one to three times the diameter of the tubular arm; the envelope further being a continuation of the tubular arm; said curved segment including a first half-shell affixed to the arms and having curved inner and outer edges formed about a common center point, with the inner edge being interposed between the outer edge and the center point; said curved segment also comprising a plurality of tongues extending from the outer edge of the half-shell, the tongues being rolled and bent towards the center of the envelope and contacting the inner edge of the half-shell.
Claim 2
Dependent Claim
186 words
A bent terminal for electrical connection comprising an arm for crimping and for connecting electrically with a conductor, a substantially tubular arm elastically deformable radially for connecting with a complementary terminal and a bent portion of fixed shape joining said arms, the bent portion comprising a curved segment defining an envelope of generally toric form, the envelope having a cross-section substantially equal to that of the tubular arm; said envelope having a radius of curvature, taken at the level of the inner generatrix for the toric form, of the order of one to three times the diameter of the tubular arm; the envelope further being a continuation of the tubular arm; said curved segment including a first half-shell affixed to the arms and having curved inner and outer edges formed about a common center point, with the inner edge being interposed between the outer edge and the center point; said curved segment also comprising a plurality of tongues extending from the outer edge of the half-shell, the tongues being rolled and bent towards the center of the envelope and contacting the inner edge of the half-shell.
Claim 3
Dependent Claim
22 words
The terminal of claim 1 in which the arms and first half-shell are integrally formed from a single piece of sheet material.
Claim 4
Dependent Claim
34 words
The terminal of claim 2, wherein the first half-shell is semi-toric and the plurality of tongues constitute a complementary portion of the curved segment integrally formed with the first half-shell for forming the envelope.
Claim 5
Dependent Claim
22 words
The terminal of claim 1 in which the arms and bent portion are integrally formed from a single piece of sheet material.
Claim 6
Dependent Claim
34 words
The terminal of claim 4 wherein the first half-shell is semi-toric and the plurality of tongues constitute a complementary portion of the curved segment integrally formed with the first half-shell for forming the envelope.
Claim 7
Dependent Claim
205 words
A bent terminal for electrical connection comprising an arm for crimping and for connecting electrically with a conductor, a substantially tubular arm elastically deformable radially for connecting with a complementary terminal and a bent portion of fixed shape joining said arms, the bent portion comprising a curved segment defining an envelope of generally toric form, the envelope having a cross-section substantially equal to that of the tubular arm; said envelope having a radius of curvature, taken at the level of the inner generatrix for the toric form, of the order of one to three times the diameter of the tubular arm; the envelope further being a continuation of the tubular arm; said curved segment including a first half-shell affixed to the arms and having curved inner and outer edges formed about a common center point, with the inner edge being interposed between the outer edge and the center point; said first half-shell being semi-toric; said curved segment also including a complementary portion connected to the first half-shell for forming the envelope; said complementary portion comprising tongues extending from the outer edge of the first half-shell, the tongues being rolled and bent towards the center of the envelope and contacting the inner edge of the half-shell.
