Male electrical terminal with a twisted contact section
View Patent ↗This terminal includes a folded contact section which has a longitudinal junction line and defines contact surfaces, a securing section, suitable to be accommodated in a terminal accommodating chamber of an insulating housing, and an intermediate section extending between said contact section and securing section. The intermediate section is deformed in torsion around the longitudinal axis (X), whereby the junction line is angularly offset from the contact surfaces around the longitudinal axis (X). The invention also relates to a process for manufacturing such a terminal, and to an electrical connector including such a terminal.
1. A male electrical terminal which is elongated along a longitudinal axis (X), integrally made from a metal sheet, and which comprises
a folded contact section which has a longitudinal junction line between two edges of the corresponding portion of the metal sheet, said contact section defining at least one contact surface to be engaged by at least one complementary contact surface of a complementary female terminal,
a securing section, suitable to be accommodated in a terminal accommodating chamber of an insulating housing, and to be engaged by a locking member of said housing so as to secure the terminal in said chamber, and
an intermediate section extending between said contact section and securing section,
characterized in that said intermediate section is deformed in torsion around the longitudinal axis (X), whereby the junction line is angularly offset from the contact surfaces around the longitudinal axis (X).
2. The male electrical terminal as claimed in claim 1 , characterized in that the contact section has a U-shaped cross-section which is substantially symmetrical with respect to a first longitudinal plane (Q).
3. The male electrical terminal as claimed in claim 2 , characterized in that it further comprises a wire connecting section which is substantially U-shaped in cross-section, said U-shape being substantially symmetrical with respect to a second longitudinal plane (P).
4. The male electrical terminal as claimed in claim 3 , characterized in that the first longitudinal plane (Q) is angularly offset from the second longitudinal plane (P), around the longitudinal axis (X).
5. The male electrical terminal as claimed in claim 4 , characterized in that the offset angle of said first (Q) and second (P) longitudinal planes is substantially equal to 90°.
6. An electrical connector comprising
an insulating housing having at least one terminal accommodating chamber, and at least one male terminal as claimed in claim 1 , the securing section of which is accommodated in said chamber.
7. A process for manufacturing the male electrical terminal as claimed in claim 1 from a metal sheet, said process comprising the following successive steps:
stamping and folding the metal sheet so as to form the contact section, the securing section, and the intermediate section, and
deforming in torsion the intermediate section with respect to the securing section around the longitudinal axis (X).
