A circuit breaker having a mechanical switch introduced into a main current path, which comprises a fixed contact and a moving contact connected to a movably mounted contact bridge. The circuit breaker comprises a drive, which is in active connection with the contact bridge, and which comprises a first drive unit and a second drive unit. The first drive unit is energized via a control circuit, and the second drive unit is connected in parallel to a resistor element introduced into the main current path. The invention also relates to a motor vehicle.

Circuit breaker

A power distributor of an electrical system of a motor vehicle, including a circuit board, which has a main connection to a main circuit and multiple secondary connections. Each secondary connection is assigned to one secondary circuit and electrically contacted with the main connection via a respective circuit breaker that has two connections. The two connections of each circuit breaker are electrically contacted directly with the circuit board.

A disconnecting device interrupts a direct current of a current path containing a hybrid switch which has a current-carrying mechanical contact system and a semiconductor switching system connected in parallel thereto. The contact system has a fixed contact and a moving contact. The moving contact is mounted on a contact bridge being coupled to a drive system moving the moving contact in a switching movement from an open position into a closed position resting against the fixed contact with a contact force. A first magnet element is mounted on the contact bridge and spaced apart from a stationary second magnet element by an air gap such that, when a current flows through the contact bridge, a magnetic field is produced in the first magnet element and the first and second magnet elements are magnetically attracted. The attraction produces a magnetic force directed in the same direction as the contact force.

A formed enclosure part for mounting an electronic component on a printed circuit board includes a receiving side having an enclosure opening for receiving the electronic component in an enclosure interior, a connection side adjoining the receiving side and having connection leadthroughs for electrical connections of the electronic component, and a mounting side having a formed-on mounting profile for positioning the formed enclosure part and holding the formed enclosure part on the printed circuit board without the use of tools. An electronic subassembly, which is also provided, receives a printed circuit board and the formed enclosure part having an electronic component disposed therein.

Formed enclosure part and electronic subassembly

A power relay for a vehicle is disclosed. The power relay has a housing formed by a connector base and a housing can set thereon, two connection bolts being inserted into the connector base for contacting a load circuit. The power relay further has a coil subassembly arranged in the housing and containing a solenoid coil and an armature. The armature is coupled by a force-transmission member to a contact bridge and can shift in the housing, under the effect of a magnetic field generated by the solenoid coil, in such a way that the contact bridge can be reversibly moved between a closing position, in which the contact bridge bridges the connection bolts in an electro conducting manner, and an opening position, in which the contact bridge is not in contact with the connection bolts. The housing can is configured as an injection-molded component made of plastic.

Power relay for a vehicle

A power relay for a vehicle, in particular a utility vehicle, is disclosed. The power relay contains a housing formed by a connecting base and a housing pot that is placed on the connecting base. Accordingly, two connecting bolts for establishing contact with an on-load circuit are formed by standard screws.

A high-voltage motor vehicle electric system contains a high-voltage battery and a consumer network which are interconnected by an electric cable, and a quick-break switch for disconnecting the high-voltage battery from the consumer network. The quick-break switch receives an airbag signal. The airbag signal is used for actuating the quick-break switch to sever the electric cable supplying power to the consumer network.

A high current switch, in particular for a motor vehicle, having a first bus bar, a second bus bar in addition to a first semi-conductor switch that has a control connection and a first transmission connection as well as a second transmission connection. The first transmission connection is placed in direct contact with the first bus bar and the second transmission connection is placed in direct electric contact with the second bus bar.

High current switch

An electrical circuit including a circuit board on which a number of electrical and/or electronic components are mounted, and a busbar that has a supporting body and a first, second, and third connection. The supporting body is spaced apart from the circuit board and the connections are brought into electrical contact both with the supporting body and with the circuit board. The supporting body has a first cross section between the first and second connection and a second cross section between the second and third connection, wherein the first cross section is smaller than the second cross section. The invention further relates to a bus bar.

High-current electrical circuit having a circuit board and a busbar

A power relay for a vehicle has a housing and two connecting bolts that are introduced into the housing so as to contact a load current circuit. The power relay further having a coil assembly that is arranged in the housing, the coil assembly contains a magnetic coil and a magnetic armature that is coupled by way of a force-transferring member to a contact bridge that can be moved in a reversible manner between a closed position and an opened position and can be displaced in the housing under the effect of a magnetic field that is generated by the magnetic coil. The contact bridge supports two contact elements that together with the mating contacts of the connecting pin form a first contact pair and a second contact pair. The contact pairs form a three point bearing arrangement in the closed position.

A switching system has two contact points and a contact link disposed so at be rotatably movable about an axis of rotation of the contact link between the two contact points. The switching system further has at least one quenching chamber and a magnetic element for producing a magnetic field being parallel to the axis of rotation of the contact link, for driving an arc produced when the contact points are open into the quenching chamber.
