There is still the main advantage that at around the electrical connection around the device parts that would hinder cable routing with the help of the angle adjustment the position of the connecting conductors an optimal place for their Feeder can be found. This results in a space-saving and lead length saving arrangement.
  • Such connections are particularly suitable for rough operation in the motor vehicle, e.g. B. in the manufacture of an electrical Connection to a solenoid valve in a fuel injection pump.
  • FIG. 1 is a section through the electrical according to the invention Device played.
  • an electrical Device e.g. B. a solenoid valve

  • this closure part made of insulating material is a mounting pin 5 with a Injected foot 6 with anchoring profile on its peripheral surface, this foot 6 has a largest diameter, on which there is a cylindrical part 7 with a smaller diameter connects, in part from the extrusion coating of the closure part protrudes towards the outside.
  • This cylindrical part forms one axially directed housing-fixed shoulder 8, which in the end with an externally threaded fastening pin 5 transforms.
  • one connection each 11, 12, e.g. the solenoid of the solenoid valve guided axially outwards, of which one terminal 11 via a clamp or weld connection with a first connection element 14 and the other terminal 12 accordingly with a second Connection element 15 is contacted.
  • These connectors are ring-shaped and with their inner bore 16 or 17 pushed over the mounting pin.
  • the first connector 14 lies directly on the shoulder 8 as a level Ring on. It is followed by an annular intermediate piece 18 Insulating material and then the annular part of the second connection element 15, the face on the annular intermediate piece comes to the plant and by not shown Stops at a radial distance from the mounting pins is held.
  • a connector 20 is also provided in the first lead 21 and a second lead 22 with their ends are injected.
  • a first is also injected Contacting extension 24 of a first connection contact 26 and a second contact extension 27 of a second connection contact 28.
  • the contacting processes stand out from an annular Part of the respective contact from, the outer edges 29 of these annular parts also still in the connector can be injected.
  • the ring-shaped parts protrude within two adjacent radial planes into an axial one Recess 30 of the connector and are from each other separated by an insulating part 31. This is radial with its inwardly facing end surface 32 on the mounting pin and also serves as a first guide for the connection element 20 on the mounting pin 5.
  • the inner diameter of the annular Parts of the contacts 26 and 28 is larger than that Diameter of the mounting pin and the inside diameter of the End face 32 of the insulating part, so that it is ensured that the contacts are not in contact with the electrical conductive material produced mounting pin 5 come.
  • the nut in the example shown electrically conductive material will be the first on the one hand Connection contact together with the second connection contact to the system brought to the second connection element 15, which in turn the first connection element 14 for fixed contacting system is held on the shoulder 8.
  • the screw part has one on the second connection contact 28 face 33 those for better contacting and also for self-assurance can be corrugated.
  • the connecting part 20 also has a cross-over the closure part ring-shaped wall 37 on the inside Form-locking surfaces with in the axial direction of the fastening bolt extending profile 38.
  • This profile can be interlocking be with circumferential flanks, what serration in a corresponding counter-toothing 39 on the outer circumference of the closure part engages.
  • FIG. 2 is a top view of a distributor injection pump 41 with solenoid valve 42 screwed on connector 20 shown.
  • the V-shaped merging can be seen here the connecting conductor to a jointly sheathed cable 43, the dissipates between injection lines 44.
