Abstract

An electrical connector configured to be mated with a mating connector along a mating direction includes a plurality of contact elements each having a contact surface at least partially inclined with respect to the mating direction. The contact elements are spaced apart from each other along a circumferential direction with respect to the mating direction.

First claim

What is claimed is:

1 . An electrical connector configured to be mated with a mating connector along a mating direction, comprising:
a plurality of contact elements each having a contact surface at least partially inclined with respect to the mating direction, the contact elements are spaced apart from each other along a circumferential direction with respect to the mating direction.

2 . The electrical connector of claim 1 , wherein the contact elements are solitary and a gap is formed between the contact elements.

3 . The electrical connector of claim 1 , further comprising a base plate, the contact elements extend along the mating direction through the base plate.

4 . The electrical connector of claim 3 , wherein the base plate has a socket, the contact elements are attached on the socket.

5 . The electrical connector of claim 4 , wherein each contact element is positioned on a separate socket.

6 . The electrical connector of claim 3 , wherein the contact surfaces face either outwards or inwards with respect to a center of the base plate.

7 . The electrical connector of claim 1 , wherein the contact elements have a same height with respect to the mating direction.

8 . The electrical connector of claim 1 , wherein each contact surface has a convex protrusion.

9 . The electrical connector of claim 1 , wherein each contact surface has a plurality of convex protrusions.

10 . The electrical connector of claim 9 , wherein a vertex of each of the plurality of convex protrusions is arranged on a surface of one of a polyhedron and a rotated body.

11 . The electrical connector of claim 1 , further comprising a part of a coupling, the coupling is one of a magnetic coupling and a mechanical coupling.

12 . The electrical connector of claim 1 , further comprising a contact pin movable along the mating direction and having an end section facing in the mating direction.

13 . The electrical connector of claim 1 , further comprising a contact pad having an end face facing in the mating direction.

14 . A connector assembly, comprising:
an electrical connector including a plurality of first contact elements each having a first contact surface at least partially inclined with respect to a mating direction, the first contact elements are spaced apart from each other along a circumferential direction with respect to the mating direction, the first contact surface of each of the first contact elements faces outwards; and a mating connector including a plurality of second contact elements each having a second contact surface at least partially inclined with respect to the mating direction, the second contact elements are spaced apart from each other along the circumferential direction with respect to the mating direction, the second contact surface of each of the second contact elements faces inwards, a plurality of contact points between the first contact surfaces and the second contact surfaces are arranged on a surface of one of a polyhedron and a rotated body.

15 . The connector assembly of claim 14 , wherein one of the electrical connector and the mating connector is a ground-side connector of a conductive charging system and the other of the electrical connector and the mating connector is a vehicle-side connector of the conductive charging system.

16 . A charging robot, comprising:
an electrical connector mounted on an end section of a robotic arm, the electrical connector including a plurality of contact elements each having a contact surface at least partially inclined with respect to a mating direction, the contact elements are spaced apart from each other along a circumferential direction with respect to the mating direction.
