摘要:
Electric fuel pumps are already known with a pump housing and a ground terminal, which is provided on a terminal cover, for making contact with an electrical ground, in which the pump housing and the ground terminal are connected to one another via a ground connection, which has a first contact section for making contact with the pump housing and a second contact section for making contact with the ground terminal. The first contact section is provided on the outer circumference of a terminal cover and, after installation, is pressed with a contact pressure against the inner face of the pump housing. Since the inner face of the pump housing has increasingly been provided with an electrically insulating anticorrosion coating, however, when the terminal cover is pressed into the pump housing, touching contact with the pump housing does take place which is usually also electrically conductive, but as a result of the electrically insulating coating has a high electrical resistance. In the case of the conveying assembly according to the invention, the impedance of the contact-making is reduced. The invention provides that the first contact section is designed to have sharp edges in such a way that, when it is pushed into the pump housing, it passes locally through an electrically insulating layer formed on the pump housing.
