Abstract

The production numbers of electrical vehicle increase and generate new issues. Car makers need to protect cars and users from not forecasted events. To protect the charging system, it is state of the art to use suitable fuses for 250 VAC power supplies. An opportunity is to install the fuses into the charging inlet by using fuses soldered on a PCB. But this solution is not robust under influence of vibrations caused by the vehicles and there is also no easy way to replace the fuses in case of damage.

Another approach to solve the problem is to integrate fuses into the harness. But the complexity of the wiring, the sealing, the time and the cost for assembly increases. It has also to be considered that the fuses have to be placed close to the heating points (terminals) and that the fuses have to be easily replaceable.

The problems above mentioned are solved by using a fused connector at the charging cable. The following pictures will describe the connector in an easy way.

Description of the invention

The problems above mentioned are solved by using a fused connector at the charging cable. The following pictures will describe the connector in an easy way.

Figure 1 shows the current guiding parts of the connector without the connector housing. The flatten ends of the fuses are connected on a first end to the wire and on the second end to the terminals.
