Definitions
- the invention is based on a contact strip according to the main claim.
- a contact strip for the common electrical contacting of a plurality of electrically actuable fuel injectors is already known, which has a contact strip housing with line channels in which the electrical lines contacting the electrically actuable fuel injectors are arranged.
- the contact strip housing has a number of plugs corresponding to the number of fuel injectors, which partially surround the fuel injectors at their ends facing away from the spray ends and have the connecting plugs in the direction of the respective valve longitudinal axis, and the connecting plugs are electrically connected tact.
- This contact strip is only suitable for side-feed and bottom-feed fuel injectors, that is to say for fuel injectors to which the fuel is supplied on its circumference and whose electrical connection takes place at its end facing away from the spraying end.
- the result is between e.g. Rigidly mounted on an intake pipe of the internal combustion engine contacting strip and the fuel injection valves to relative movements that can lead to high wear on the contact elements of the plug of the contacting strip and the connecting plugs of the fuel injection valves.
- the contact strip according to the invention with the characterizing features of the main claim has the advantage of ensuring simple and reliable contacting of a plurality of electrically actuable fuel injection valves, which can be of any type.
- the carrier part connected to the contact strip housing and having at least one conductor channel can be produced in a very simple and inexpensive manner and permits a very compact design of the contact strip according to the invention.
- the electrical contact lines protruding from the contact strip can be provided with various electrical plug elements, so that the contact strip can be used variably for contacting different fuel injection valves.
- the separate contacting of the individual fuel injection valves enables the fuel injection valves to move freely to compensate for tolerances during assembly and for temperature-related expansions during operation of the internal combustion engine. Also find Despite the vibration stress during operation of the internal combustion engine, there are almost no relative movements between the fuel injection valves and the respective electrical plug-in elements.
- the contact strip according to the invention allows the formation of an assembly and service-friendly, from the contact strip and e.g. an existing overall system. Checking an individual fuel injector is possible without any problems.
- the attachment of the fuel distributor, for example to an intake pipe of the internal combustion engine, is independent of the attachment of the contact strip, so that the contact strip can also be removed individually.
- the contact strip itself can be produced in a simple and inexpensive manner.
- the side surfaces of the at least one groove-shaped conductor channel of the carrier part are formed by two adjacent webs each formed on the carrier part, so that the groove-shaped conductor channels can be formed particularly easily.
- the carrier part is connected to the contact strip housing by means of a snap-in connection.
- the contact strip housing is formed by at least partially plastic and injection molding of the carrier part. It is advantageous if the carrier part is part of the contact strip housing. A contact strip designed in this way can be produced particularly easily and inexpensively.
- the at least one electrical connecting line is held in the respective conductor channel of the carrier part by thermal deformation of the carrier part consisting of plastic.
- the contact strip can be connected to a fuel distributor by means of a latching connection and thus in a simple manner.
- an electrical connector plug serving for electrical connection of the contact strip is also molded onto the contact strip housing.
- FIG. 1 and 2 show a contact strip designed according to the invention in accordance with a first, a second or a third exemplary embodiment
- FIG. 3 shows a section along the line III-III in FIG. 1 in accordance with the first exemplary embodiment with a fuel injector
