The J1772 SAE Specifications state in Section 4: General Conductive Charging 4.7.5 Latching The coupler shall have a latching mechanism to prevent inadvertent or accidental decoupling. The latching mechanism should provide a means in the connector to open the proximity detection conductor (see 4.2.2) when disengaging from the vehicle inlet. 4.7.6 Locking Function The coupler locking function is intended to reduce the likelihood of tampering with, or an unauthorized removal, of the vehicle connector from the vehicle inlet.
