Charging arrangement for charging of electric vehicles
An arrangement for charging of electric vehicles includes a charging connector and a charging cable. The connector includes a connector body with first and second zones, the two zones being separate from each other. The first zone hosts a mating interface with electrical contacts for mating the connector with a corresponding socket of an electric vehicle. The electrical contacts are electrically coupled to the cable. The second zone includes a tube in which the cable is guided from an opening of the tube, which is arranged on that side of the second zone that faces away from the first zone to the electrical contacts, which are located in the first zone, and a handle for grabbing the connector with a human hand, the handle being separate from the tube. The second zone is Y-shaped where the tube is formed by one upper leg and the lower of the Y.
1. A charging arrangement for charging of electric vehicles, comprising a charging connector and a charging cable, wherein:
the charging connector comprises a connector body with a first zone and a second zone, the first zone and the second zone being separate from each other,
the first zone of the connector body hosts a mating interface with electrical contacts for mating the charging connector with a corresponding socket of an electric vehicle, the electrical contacts being electrically coupled to the charging cable, and
the second zone of the connector body comprises a tube in which the charging cable is guided from an opening of the tube that is arranged on a side of the second zone of the connector body that faces away from the first zone of the connector body to the electrical contacts, the electrical contacts being located in the first zone of the connector body, and a handle for grabbing the charging connector with a human hand, the handle being separate from the tube, wherein:
the second zone of the connector body is Y-shaped wherein the tube is formed by one upper leg and the lower of the Y and the handle is formed by the other upper leg of the Y, and
the connector body has a multi-layer structure with a stiffer core layer and a softer outer layer,
wherein the stiffer core layer is made from a glass-fiber filled polymer material or from a TPU-based material.
2. The charging arrangement for charging of electric vehicles according to claim 1 , wherein the first zone and the second zone are directly adjacent to each other.
3. The charging arrangement for charging of electric vehicles according to claim 2 , wherein the second zone of the connector body is attached to the first zone of the connector body with both upper ends of the upper legs of the Y.
4. The charging arrangement for charging of electric vehicles according to claim 1 , wherein the tube is curved.
5. The charging arrangement for charging of electric vehicles according to claim 1 , wherein the lower end of the Y comprises the opening of the tube that receives the charging cable.
6. The charging arrangement for charging of electric vehicles according to claim 1 , wherein the two upper legs of the Y are connected to each other by at least one bridge for reinforcing the handle.
7. The charging arrangement for charging of electric vehicles according to claim 1 , wherein the connector body comprises at least two half shells in which the mating interface with the electrical connectors are held and that are held together with at least one screw that is located outside the mating interface.
8. The charging arrangement for charging of electric vehicles according to claim 1 , wherein the connector body is comprised of at least one single body in which the mating interface with the electrical connectors are held by at least one screw that is located outside the mating interface.
9. The charging arrangement for charging of electric vehicles according to claim 1 , wherein the connector body is made from glass-fiber filled polymer material and/or from a thermoplastic polyurethane based material.
10. The charging arrangement for charging of electric vehicles according to claim 1 , wherein the softer outer layer is only partially covering the stiffer core layer.
11. The charging arrangement for charging of electric vehicles according to claim 1 , wherein the softer outer layer is rubber based or made from a thermoplastic elastomer.
12. The charging arrangement for charging of electric vehicles according to claim 1 , wherein the multilayer structure is achieved by multilayer injection molding or by double shot molding or by additive manufacturing featuring a two-nozzle feeding system.
