Sleeve for socket contact, connector using the sleeve, and manufacturing method
Disclosed is a sleeve for a female contact, its method of manufacture, and also a connector using the sleeve. The sleeve is provided with a first end and a second end presenting, respectively, a rotary symmetry around a common axis, the ends being inter-connected by a plurality of contact blades. Each contact blade presents connecting sections linking the median part of the blade to the first and the second end respectively. The connecting sections describe at least one truncated surface. Applications include the implementation of connectors for high intensity currents, usable especially for electric vehicles.
1. A metal sleeve article for a female connector, the sleeve article comprising:
a first end part and a second end part having rotary symmetry around a common axis, said first end part having a first diameter, said second end part having a second diameter; and
a plurality of contact blades interconnecting said first and second parts, each of said plurality of contact blades having a median part and connecting sections linking the median part respectively to said first and second end parts, the median parts being positioned along a median cylinder centered on the common axis and having a diameter less than the first and the second diameters of said first and second end parts, the connecting sections of said plurality of contact blades extending between the median cylinder and said first and second end parts by describing at least one truncated surface wherein the connecting sections of each of said plurality of contact blades share the common axis and form a non-zero angle relative respectively to a plane passing through a middle of the median part of the contact blade, wherein the median part is respectively parallel to said plane and to the common axis.
2. The metal sleeve article of claim 1 , wherein the median parts of said plurality of contact blades have a wide side perpendicular to a radius of the median cylinder.
3. The metal sleeve article of claim 1 , wherein said first and second parts are cylindrical.
4. The metal sleeve article of claim 1 , wherein said first and second end parts have a truncated shape with a small base defining the first and second diameters respectively, the small base being toward said plurality of the contact blades.
5. The metal sleeve article of claim 1 , said first and second diameters being identical.
6. The metal sleeve article of claim 1 , said plurality of contact blades being between 10 and 18 contact blades.
7. A female connector having the metal sleeve article of claim 1 .
8. The female connector of claim 7 , further comprising:
at least one socket with a cylindrical bore, the metal sleeve article being housed in the cylindrical bore.
9. The female connector of claim 8 , wherein the cylindrical bore has a shoulder defining a stop of at least one of said first and second end parts.
10. An assembly of a male connector and the female connector of claim 7 , the male connector having a cylindrical contact pin having a diameter that is between a diameter of the median cylinder and a smaller diameter of the first and second diameters of said first and second end parts.
