Definitions

  • the invention relates to a contacting element, in particular Zündwoodss kind in internal combustion engines, with an outer sleeve, inside which an axially acting compression spring is provided.
  • the ignition of the gas filling in the cylinders is effected by means of sparks produced by spark plugs.
  • the ignition voltage required for ignition is supplied by an ignition device, an ignition coil, via a rigid connection or an ignition cable.
  • the respective voltage supply contacting elements consist of a sleeve in which there is an axially acting compression spring.
  • the compression spring When attaching to the spark plug, the compression spring is pressed against the spring pressure in the sleeve. This creates a good transitional contact between the power supply and the spark plug.
  • the conventional compression spring of the known contacting element is wound from spring steel strip and moves out with the directed to the spark plug end of the sleeve.
  • the compression spring is made of spring bronze or copper.
  • the spring does not come out of the outer sleeve, because the cup closes the outer sleeve to the outside.
  • the corona effects can not easily act on the parts within the contacting element and not easily cause corrosion, especially on the spring.
  • the sliding cup allows a tolerance compensation.
  • the second stop for the cup is provided with the other spring end to a socket which is inserted into the outer sleeve.
  • the second stop can thus be mounted after the spring and the cup.
  • the bush and the outer sleeve can be connected to each other by means of a screw connection, in particular on the outer diameter of the sleeve and the inner diameter of the outer sleeve.
  • the bushing can be extended within the outer sleeve so that it guides the compression spring in the outer sleeve.
  • the spring coils are applied to the inner walls of the socket.
  • the parts of the contacting element may be made of any current-conducting material, in particular metal.
  • all parts of the contacting element consist of material which is insensitive to corrosion.
  • the outer sleeve with the end in which the cup is displaceable can be placed on the contacting end of a spark plug and the other end of the outer sleeve is connected to an ignition voltage supply.
  • the outer sleeve with the end in which the cup is displaceable on a spark plug preferably placed so that the contact end of the spark plug against the mechanical resistance of the spring with displacement of the cup in the contacting element and this case, the contact end of the spark plug more preferably at least partially conically tapered, so that the outer surfaces of the outer conical surfaces of the contact end of the spark plug bear against the correspondingly shaped, outwardly open inner walls of the cup base.
  • the ignition voltage is supplied directly via an ignition voltage contact of an ignition coil.
  • the entire region of the Zündnapsszu Entry is surrounded with the Zündnapssitch and the contacting element by means of insulating material, except for at least the cup contact surface, which serves to contact with the spark plug contact.
  • the ignition voltage can be supplied via a resistive element, which is e.g. in a ceramic shell, which in turn is covered by a shell of e.g. PTFE-based material is enclosed, wherein one end of the resistive element is connected to the contacting element and the other end of the resistive element with a connector to an ignition cable, which is in communication with the ignition coil connected.
  • a resistive element which is e.g. in a ceramic shell, which in turn is covered by a shell of e.g. PTFE-based material is enclosed, wherein one end of the resistive element is connected to the contacting element and the other end of the resistive element with a connector to an ignition cable, which is in communication with the ignition coil connected.
  • the connecting piece is cast with the ignition cable and the resistance element by means of an insulating material.
  • the contacting element may be at least partially encapsulated with the resistive element by means of an insulating material.
  • the potting compound is preferably in all cases of a two-component epoxy resin.
  • a contacting element 1 shown in FIGS. 1 and 2 serves, for example, to connect a voltage supply to the spark plug.
  • the contacting element can also be used for other contacting purposes. Examples of contacts are shown in Figs. 5 and 6 and will be described later.
  • an outer sleeve 2 of the contacting element 1 there is a compression spring coiled from spring steel wire 4.
  • the outer sleeve 2 merges with a sleeve end 5 into a contact section 5a serving as a feed part.
  • the outer sleeve 2 is closed and thus forms for the compression spring 4, a first stop 6.
  • the compression spring 4 is located at a spring end 7 at.
  • the other spring end 8 is located in a cup 9 with a cup wall 10 and a cup bottom 11.
  • the outer sleeve 2 is open in the region of the other spring end 8 before assembly.
  • the compression spring 4 can be inserted with the cup 9 in the interior 3 of the outer sleeve 2.
  • a bush 13 is inserted into the open end 12 of the outer sleeve 2.
  • the sleeve 13 is provided on its outer side 14 with a thread.
  • the inner side 15 of the outer sleeve 2 is provided with a thread.
  • the threads are not shown, because they are not absolutely necessary. Namely, the socket 13 becomes either screwed by means of the thread in the outer sleeve 2 or - if no threads are provided - glued or welded.
  • the sleeve 13 has on its inside a second stop 16.
  • This second stop 16 holds the cup 9 in the socket 13, which in turn is at least partially located in the outer sleeve 2, against retraction.
  • the cup 13 can thus be pushed further into the outer sleeve 2 or sleeve 13 when a part, for example a spark plug contact 17 (FIG. 5) is pushed in the direction of an arrow 17a, against the action of the compression spring 4, resulting in a good pressure contact. Vibrations and building tolerances are suppressed.
  • the bush 13 is provided in the interior 3 of the outer sleeve 2 with an extension 13 a, which is so long that it can lead the compression spring 4 completely or almost full length. Preferably, it pushes - fully assembled - against the first stop. 6
  • the contact section 5a of the outer sleeve 2 has an axial bore 18 into which an ignition voltage contact 19 (FIG. 5) or an ignition cable 20 (FIG. 6) can be inserted for ignition voltage supply.
  • the contact portion 5a is provided according to a particular embodiment with a collar 21, the wall openings 22 has.
  • a terminal 23 shown in Fig. 4 is clickable.
  • Contact pieces 24 of the terminal 23 engage through the wall openings 22.
  • Fig. 3 shows the individual parts of the contacting element 1, such as outer sleeve 2 with contact portion 5a, compression spring 4, cup 9, sleeve 13 with extension 13a in an exploded view. All of these parts 2, 5a, 4, 9, 13 and 13a are made of any electrically conductive material.
  • This electrically conductive material may be, for example, copper.
  • a corrosion-insensitive material comes into consideration.
  • an alloyed steel is used, which is commercially available under the name V2A or V4A.
  • the spring clip 23 is preferably made of V2A or V4A - steel.
  • An ignition coil 25 has a rod-shaped insulating body 26 through which the ignition voltage contact 19 serving axially of the ignition voltage supply extends.
  • an adapter 27 is inserted, which engages in the interior 28 of the insulating body 26 with a support sleeve 27a.
  • the adapter 27 is preferably made of silicone and guides the contacting element 1.
  • a support ring 29 serves to guide a spark plug 30.
  • the spark plug 30 presses the cup 9 in the assembled state in the interior 3 of the outer sleeve 2. This creates a higher contact pressure.
  • the contacting element 1 is encapsulated with the adapter 27 and the ignition voltage contact 19 by means of an insulating compound, preferably by means of a two-component epoxy resin. In this way, corona effects are prevented in this area. Oxidation-initiating effects do not affect the contacting element 1 made of V2A steel.
  • Fig. 6 shows an application of the contacting element 1, in which the contacting element 1 at one end 31 of a resistor indicated by the numeral 31a, e.g. an inductive resistor, which is located in a ceramic shell 32.

  • the whole assembly is enclosed by a sheath 35 of PTFE-based material.
  • the ignition cable 20 is potted with the transition piece 34 and the ceramic resistor 32 by means of an insulating material.
  • the contacting element 1 is encapsulated with the ceramic resistor 32 by means of an insulating material apart from the contact surface of the cup 9.
