Due to the high energy to be transmitted, usually at several hundreds of volts, great demands are made on the composition of the charging connectors. In current designs, there is a risk of undesired flashovers between conducting components and fixing materials as, e.g., screws. Further, there is poor protection against mechanical damage and poor protection against dust and water ingress.
- the described embodiments similarly pertain to the charging connector for charging a battery of a vehicle, the mating interface for a charging connector, the charging station comprising a charging connector, and the charging infrastructure. Synergetic effects may arise from different combinations of the embodiments although they might not be described in detail.

- the blockers may be, for example, a signal contact blocker and / or a DC blocker. That is, instead of using screws, clips are used to attach the blockers to the contact compartment housing, thereby providing favorable dielectric properties of the arrangement.
- the internal mechanical connector comprises walls having surfaces oriented towards the front end of the charging connector and which are configured to press the at least one blocker against the contact compartment housing.
- the internal mechanical connector itself has no means as, e.g., clips for fixing the blockers to the contact compartment housing.

- the external mechanical connector is the third layer of mechanical protection of the contacts. It also adds water ingress protection to some extent, although limited. Therefore, the external mechanical connector may be provided with drains to improve the IP rating.

- Charging stations transfer electrical power of several kW from the station to an electrically powered vehicle. The stations are fit with charging connectors that provide the electrical connection between the charging station and the vehicle.

Fig. 1 , the contact compartment housing 106 comprises five cylindrical compartments, which are passing through theplate 124, which defines the position of the contact compartments. The left side of the contact compartment housing 106 comprises thefront end 126 and the other side theback end 128. The contact compartments 106 are built without screws, and utilizeblockers 108 to keep the contacts in position. Theblockers clips 110 that attach them to the contact compartments 106. They are pressed against the contact compartments 106 bywalls 120 which are arranged inside the internalmechanical connector 104, the internalmechanical connector 104 being inside the external mechanical connector. The normal vector of the surface of the walls has the same direction asarrow 122, which points to the direction, where the vehicle will be connected. Thedirection 122 indicates also the direction of "front" ends or "front" parts. The volume of the contact compartments 106 not filled with contacts or blockers is occupied by a potting resin, or can also be protected by sealings in the front and in the back. In such way, the compartments reach IP67 or IP68. - The contact compartments 106 are coupled with the front part of an internal
mechanical connector 104. The back part of the internalmechanical connector 104 receives the cable to the charging station with the Cu conductors. Acable gland 112 seals the entrance of the cable. By such an arrangement, the internalmechanical connector 104 is dustproof and waterproof, fulfilling the ratings IP67 or IP68. - The internal
mechanical connector 104 can be pushed into themating interface 114. Themating interface 114 with the internalmechanical connector 104 can then be enclosed by the two parts of the externalmechanical connector 102 and locked together. The externalmechanical connector 102 represents the third layer of mechanical protection of the contacts and further provides a water ingress protection. Drains may be included in the externalmechanical connector 102 to improve the IP rating. - The presented arrangement allows to replace the mating interface or the external mechanical connector parts very easily.
- In the following, materials are proposed that ensure the mechanical robustness and the protection against external environmental conditions as humidity, intrusion of water and dust, etc.
- The
mating interface 114 may, for example, be made of a flexible and extremely tough material, such as thermoplastic polyurethane elastomers (TPU, TPE). By using of TPU/TPE mechanical damage can be avoided in all conditions. A specific grade with high hardness may be selected so that the flexible material is stiff enough to hold the weight of the connector and the cable during charging also at high ambient temperature, e.g., above 30°C. As an alternative, the mating interface may be made of a relatively stiff material which is tough at low temperature, such as polycarbonate and blends thereof or some polyamides impact modified, with or without glass fiber reinforcement. - The preferred materials for the external
mechanical connector 102 may be polycarbonate and blends, and some types of polyamides so that theconnector 102 is sufficiently stiff but mainly tough at low temperature to avoid mechanical damage. - The requirements for internal parts, i.e., the contact compartment housing 106 and the
blockers 116 focus on a high comparative tracking index (CTI) and low moisture absorption to minimize the risk of dielectric failures. At the same time, the part should be stiff and have good mechanical strength. The preference is therefore on some types of polyamides with high CTI. - Similar to the external
mechanical connector 102, polycarbonates may preferably be used for the internalmechanical connector 104 and thecable gland 112. In case that the internalmechanical connector 104 is welded to the contact compartments housing 106, the same material as the contact compartment housing 106 should be used, i.e., for example, polyamide with high CTI. -
