Abstract
Abstract A contact strip which includes a contact strip housing and a support part, which has conductor channels with connection leads extending within the conductor channels. Projecting from the contact strip are electrical connection leads in a lead line which serve to contact the fuel injection valves and which are fitted with plug elements, which contact electrical conductors of the fuel injection valves. The contact strip has an advantage of providing a contact to several fuel injection valves, which may be of any kind of construction, in a simple and reliable manner. The contact strip is particularly suitable for making common electrical contact to electrically operated fuel injection valves of internal combustion engines.
