Definitions
- the invention relates to a switch contact for a Starter motor with the in the preamble of claim 1 mentioned features.
- the switch contact according to the invention for the starter motor can be a multi-stage for the first time Switching can be realized without an additional Interconnection effort is necessary.
- the Switch contact can be designed very compact, so that its space requirement is minimal. In addition can significantly reduces the risk of contact welding become.
- the first contact element is in an open Switch position and / or at least at the beginning the first switch position in a rest position Holding force applied.
- This can preferably be such that the first Contact element from a counter contact element facing contact body and a spring element, which is the first contact element in the relaxed Condition moves to the rest position.
- the first contact element in one Insulated bushing with an end stop for the rest position by one to the counter contact element facing inner edge of the insulating sleeve becomes.
- the first contact element or the contact body in the form of a carbon brush realize is further preferred. If a spring element is provided, then this preferably electrically conductive and / or A strand is assigned to the spring element, the one electrical connection enabled. Furthermore it is advantageous to the second contact element made of copper shape to a very high electrical conductivity to grant.
- the switch contact can be designed as a wedge contact.
- the mating contact element is a wedge and the first contact element has a complementary one conical contact shape. The selected geometry enables a self-cleaning effect of the contact surfaces.
- the Integrate switch contact that starts from the open switch position simultaneously or on top of each other are contactable below. That's the way it is for example conceivable, the first contact element a resistance carbon and a subsequently contacted Another contact element made of high-current coal shape (double carbon contact).
- the main stream is in of such an embodiment only activated, if the mating contact element on the second contact element, which is generally the best has electrical conductivity. All in all can be by such an embodiment of the Switching contact several closed switching positions, in which a current flows - in the exemplary embodiment three closed switch positions - realize and so a starting process can be essential be made more comfortable.
- FIG. 1 shows a schematic sectional view a first embodiment of a switch contact 10, as used in a starter motor M of internal combustion engines Can be found.
- the switch contact 10 consists of a counter-contact element 12, a first contact element 14 and a second contact element 16.
- the individual components 12, 14, 16 are shiftable relative to each other, that is, in this case is done by appropriate mechanics a displacement of the mating contact element 12 in Direction of the two contact elements 14, 16 allows. If the mating contact element 12 to the Contact elements 14 and / or 16 is present, so a Circuit closed and a flowing current can enable the operation of the starter motor M.
- the first contact element 14 is according to the present Embodiment executed in two parts and consists of a contact body 18 on one Counter-contact element 12 facing side and one Spring element 20 on the side facing away from it.
- the first contact element 18 is also located in FIG an insulating bushing 22.
- the insulating bushing 22 has a total of three functions. She leads the first Contact element 14 and insulated between them two contact elements 14 and 16. In addition it forms an end stop 24 for the first Contact element 14 by one to the counter contact element 12 facing inner edge of the insulating bush 22 is provided.
- the switch body 18 of the first contact element 14 consists of a conventional carbon brush material. This reduces the risk of contact welding during a switching operation.
- the spring element 20 must be sufficiently electrically conductive to enable an electrical connection. With insufficient thermal strength of the spring element 20 or to low electrical conductivity can the spring element 20 a strand can be assigned.
- the second contact element 16 is based on a very good electrical conductor, for example copper, shaped. Accordingly, an electrical resistance of the second contact element 16 much less than an electrical resistance of the first contact element 14.
- a sequence of the switching process can be the executions a) to f) of FIG. 2.
- Step a) In a open switch position are the counter contact element 12 and the contact elements 14, 16 so far spaced from each other that no current can flow (Step a)).
- the contact body 18 of the contact element 14 is such by the spring element 20 force applied to the end stop 24 is present.
- step b) is now the counter-contact element 12 with one here Mechanics not shown in the direction of the first Move contact element 14. In dependence of the applied voltage and the selected materials arises when falling below a certain A switch-on arc 26 at a distance.
- step c When the mating contact element 12 on the first contact element 14 is present (step c)), a first closed switch position assumed.
- the first Contact element 14 then represents a resistor RV and the resulting relatively low current flow enables a comfortable, safe engagement of a Starter pinion in an engine ring gear.
- step d Since the electrical resistance of the second contact element 16 is much less than the RV resistance first contact element 14, almost takes place entire power line through this contact and that first contact element 14 is almost de-energized.
- the starter motor M can now flow the main current a maximum moment on his starter pinion and subsequently transferred to the motor sprocket.
- step e) the counter contact element 12 again in the opposite direction move, a restoring force of the spring element 20 can be exploited.
- Mating contact element 12 still on the first contact element 14 this in turn represents the resistance RV represents and the resulting, relatively small Current flow can be started with the starter motor M feasible switching stages can be used.
- An im Step f) arcing arises with increasing distance of the counter-contact element 12 and of the first contact element 14 deleted and ultimately then the switch contact 10 is again in the open switch position of step a).
- FIG. 3 is a second alternative embodiment of the switching contact 10 in three different Switch positions. On the presentation the wiring is for reasons of clarity been waived.
- the switch contact 10 is a wedge contact molded.
- the counter contact element 12 has a wedge and the first contact element 14 a complementary conical contact form in one Area 28.
- the switch contact 10 On the left side of Figure 3 is the switch contact 10 shown in the open switch position. Subsequently, it is closed in a first Switch position and on the right side then in a second closed switching position shown. In the first closed switch position is the counter-contact element 12 in Area 28, but is not yet on the second Contact element 16 on.
- a material from the selected first contact element 14 such that be Resistance is greater than that of the second contact element 16, so that after closing the circuit current flow occurring is relatively low and used to engage the starter pinion can.
- the current initially flows over a resistance range R of the first contact element 14, then over a portion of the second contact element 16 and is subsequently on the spring element 20th transfer.
- Frictional forces for self-cleaning of the contact surfaces be used.
- Spring element 30 is provided next to the spring element 20 the necessary restoring force is available can put.
- a further contact element 32 in addition to the first and second contact element 14, 16 also a further contact element 32 may be present.
- the further contact element 32 consists of a contact body 34 and a spring element 36.
- the Contact body 34 is based on a high-current carbon realized.
- the spring elements 20 and 36 are sufficiently high have electrical conductivity.
- the contact body 18 of the first contact element 14 consists of a Resistance coal.
