摘要:
An electronic circuit includes a conductor path on a circuit board, and at least one SMD component, electronic component and/or electromechanical component mounted on the circuit board and connected to the conductor path. A circuit connection is established via a soldered joint and a spring-loaded or stressed springy contact bridge that provides fuse protection. In the event of excessive power dissipation or high temperature, the soldered joint melts or softens and the contact bridge springs open to interrupt the circuit.

An electronic assembly includes an electronic circuit on a circuit board. The circuit includes a conductor path on the circuit board, and at least one SMD component, electronic component and/or electromechanical component that is mounted on the circuit board and connected to the conductor path. A circuit connection between any two of the conductor paths and/or the components is established via a soldered joint and a spring-loaded contact bridge. In the event of excessive power dissipation, the soldered joint melts or weakens and the contact bridge opens due to the spring force.

An electronic assembly (1) with a circuit board (2) that is provided with conductor paths or strips (6) and, for forming an electronic circuit, is equipped with a number of SMD components (4) and/or further electronic and/or electromechanical elements through use of a suitable solder, shall be secured with simple means against high power dissipation. For that purpose, according to the invention, a number of connections between conductor strips (6), components and/or elements is produced via respectively one spring-loaded contact bridge (12, 12′, 12″, 12′″).

In order to protect a printed circuit board (1, 1′) especially against the development of heat by simple means, said printed circuit board includes strip conductors for electronic circuits and connections for a voltage supply unit equipped with at least one SMD-component and additional electronic and/or electromechanical parts that are soldered in a suitable manner. The voltage supply unit is connected to one or several supplying strip conductors (2). At least one of the supplying strip conductors (2) includes a break to this end which is bridged in a conductive manner by means of a fuse bridge (6), said fuse bridge (6) containing or being made of a basic material, the melting point of which is lower than the melting point of the material of which the strip conductors are made.

2.1. Existing valve control devices are set up in housings that feature also the complete yoke in addition to the valve spools.2.2. In order to reduce the assembly effort required as well as the play of the valve domes on the inside of the spool, yoke arrangements are mounted externally on the housing.2.3. Such valve control devices are suitable for antilock braking systems, anti-slip control systems, electronic brake servos, and electronic stabilizing programs in motor vehicles.
