Definitions

  • the invention relates to an adapter for electrical connectors on fuel injectors according to the preamble of the main claim.
  • the electrical contact between an actuator of a fuel injector and the voltage source usually takes place via a plug connection system, in which the plug is shaped such that it can be positively inserted into the plug connection on the fuel injector.
  • the plug and the plug connection can be produced by injection molding from plastic.
  • the connector should also be such that the electrical contacts are sealed from the environment to protect against corrosion to counteract subsequent contact weaknesses.
  • a disadvantage of known plug-in connection systems is, in particular, the high production expenditure which arises when changes to the plug or plug connection of the fuel injector have to be implemented.
  • the requirements of different customers can be caused by customer-specific shapes
  • Plugs can only be realized using vfcj-o uieden injection molds as well as extensive assembly and disassembly of the molds, which leads to long set-up times.
  • the adapter according to the invention for electrical plug connections for a fuel injector with the features of the main claim has the advantage that changes in the shape of the mating connector only require changes in the shape of the adapter, but not in the form of the plug connection of the fuel injector, which are easy to implement and therefore can be implemented quickly and inexpensively.
  • the adapter is characterized by a reliable seal of the electrical contacts from the environment.
  • seals between the mating connector and the adapter or between the adapter and the plug connection of the fuel injector can be designed variably as radial or axial seals depending on the requirements placed on the plug connection.
  • the elastic spring tongues at the ends of the contact lugs of the adapter, the mating connector and / or the plug connection ensure reliable contacting and protection against arbitrary loosening of the plug connection by clamping action.
  • the adapter is advantageously secured by a spring clip on the plug connection of the fuel injector, as a result of which an easier connection to the mating connector of the electrical line can be achieved.
  • Fig. 1 is a schematic section through an embodiment of an adapter designed according to the invention.
  • FIG. 2 shows a schematic section through the adapter according to the invention shown in FIG. 1 along the line II-II in FIG. 1.
  • Fig. 1 shows a schematic sectional view of an adapter 1 designed according to the invention for connecting a plug connection 4 of a fuel injector with a mating connector 6 of an electrical line, the z. B. leads to an electronic control unit, not shown.
  • the mating connector 6 can be connected to the fuel injector via the adapter 1 and allows electrical contacting to actuate the fuel injector.
  • the adapter 1 is in the form of a round or oval cylindrical body 9, which can be plugged with a first end 3 onto the plug connection 4 of the fuel injector and with a second end 5 into the mating connector 6 of the electrical line.
  • the plug connection 4 of the fuel injector is designed in the form of a sleeve 15, which is preferably made of plastic and is also molded on when the fuel injector is overmolded.
  • the sleeve 15 projects beyond those required for contacting Contact lugs 14, which are connected, for example, to an actuator of the fuel injector, not shown.
  • the sleeve 15 is pushed into a recess 16 of the adapter 1, in which a first seal 7 is arranged on a recess base 19 of the recess 16, which in the present exemplary embodiment is designed as an axial seal 7.
  • the sleeve 15 is in sealing contact with the first seal 7, so that the contact tabs 14 of the connector 4 are sealed against the environment.
  • the contact lugs 14 of the plug connection 4 are arranged next to one another and are in electrically conductive connection with contact lugs 10 of the adapter 1 via elastic spring tabs 12 formed on the contact lugs 10 or 14.
  • the elastic spring tabs 12 are shown in FIG. 2 for clarification in a sectional view and described in more detail.
  • the mating connector 6 of the electrical line is inserted into a second end 5 of the adapter 1.
  • the mating connector 6 shown in FIG. 1 is a so-called AKD connector, which also has two contact runs 13.
  • the contact tabs 13 can also be conductively connected to one another by means of elastic spring tabs 12, which can either be formed on the contact tabs 13 of the mating connector 6 or on the contact tabs 10 of the adapter 1.
  • the spring tabs 12 are formed on the contact tabs 13 of the mating connector 6.
  • the adapter 1 has at its second end 5 a sleeve 17 which extends into a recess 18 in the mating connector 6. Between the contact threads 13 of the mating connector 6 and the sleeve 17 of the adapter 1, a second seal 8 is arranged, which seals the contact tabs 13 of the mating connector 6 against the environment.
  • the second seal 8 is designed as a radial seal ⁇ in the form of a shaft ring or a labyrinth seal.
  • the adapter 1 can be secured after being plugged onto the plug connection 4 of the fuel injector by means of a spring clip 11 or a similar securing device, which prevents the adapter 1 from slipping off the plug connection 4 and at the same time facilitates the insertion of the mating connector 6 into the adapter 1.
  • the mating connector 6 is preferably made of plastic, the contact tabs 13 of the mating connector 6 being injected into the plastic.
  • an additional component in the form of the adapter 1 a complete sealing of the contact lugs 13 and 14 by means of the seals 7 and 8 can be achieved and long set-up times and expensive tools for producing and assembling different connector systems can be dispensed with.
  • FIG. 2 shows an excerpt of a sectional view of a section along the line designated II-II in FIG. 1 through the connection point between the contact lug 10 of the adapter 1 and the contact lug 13 of the mating connector 6.
  • Corresponding components are provided with the same reference numerals.
  • connection between the plug connection 4 of the fuel injector and the adapter 1 on the one hand and between the adapter 1 and the mating connector 6 of the electrical line on the other hand must be easy to insert and have a certain stability to tensile load.
  • This can take place 12 which may be formed on the contact lugs 10, 13 and 14 of the adapter 1, the mating connector 6 or the male terminal 4 by means of 'the hinted already described in Fig. 1 the resilient spring tongues.
  • the elastic spring tongues 12 are formed on the contact tabs 10 of the adapter 1 facing the plug connection 4, into which the contact tabs 14 of the plug connection 4 are inserted, while on the opposite side on the contact tabs 10 of the adapter 1 facing contact lugs 13 of the mating connector 6, the elastic spring tongues 12 are formed so that the contact lugs 10 of the adapter .1 are inserted into the spring tongues 12 of the contact lugs 13.
  • the invention is not limited to the exemplary embodiment shown and can be produced for any form of mating connector 6.
