PerforMore is a bipolar high-voltage connector for use in electric vehicles
ensures quick locking. The lever is opened to the end stop for insertion, and then simply pressed downward for locking. Thanks to the two-stage locking system, removal is safe and user-friendly. A high-voltage interlock loop (HVIL) monitors the connection; when unmated, it sends a signal to the control unit which disconnects the system from the power supply. For the first step of the unmating procedure, the lever is opened until
slightly blocked, meaning the HVIL has now been interrupted. The second step involves pressing a button on the top of the connector to allow the lever to be opened fully and the connector to be disconnected. This mechanism ensures a time interval between the disconnection of the HVIL and power contacts. The power contacts are not unmated until the second step of the unlocking procedure in order to protect the user from accidental unmating under load and the resulting electric arcs. At high voltages, electric arcs can cause severe injuries; user protection is therefore the highest priority. When unmated, the PerforMore is
IP2X touch-proof to prevent users from touching voltage-conducting parts. Mechanical coding with four possible codes reliably prevents mis- mating, while colour-coding enables clear allocation of corresponding connector pairs.
PerforMore can be mounted quickly and safely using preassembled cables
EASY, EFFICIENT MOUNTING Connector installation is uncomplicated and user-friendly. On the connector side, usually permanently installed, the connection is made to the busbar or cable using a screw connection. This means the
outlet can be flexibly and infinitely adapted to the installation space, for example in an inverter. Crimping or welding can take
place on the socket, the flying connector. Mounting takes place with prefabricated cables that are simply inserted into the housing until they become noticeable and audibly locked into place. Incorrect mounting is not possible because the cable can be integrated into only once prescribed direction. Mounting is completed after closing the sealing cover, which is also inserted into the housing until it locks in. The cable assembly process is
suited for both mass and limited production. High-voltage non- metallic sheathed cables with cross sections of 50-90mm2
enable
currents with low temperature rise and high peak currents. Upon delivery, the connectors are mostly pre-mounted and the cables can pre- assembled; this saves time and lowers costs when assembling the vehicle.
