Distributor connection module for telecommunication and data technology

A printed-circuit board and a method for the precise assembly of electronic components on a surface of the printed-circuit board, the electronic components being electrically and conductively attached to printed-circuit board by a reflow soldering technique. For this purpose, a printed-circuit board is used that has sections for receiving electronic components on its surface. The sections being at least partially adapted to the outside contour of respective electronic components. The sections are configured as slotted contours or grooves and shaped to secure that the electronic components mounted after the application of solder paste are held in their desired positions prior to the actual soldering process. In addition, the assembled printed-circuit board can be connected to a housing composed of dome-type extensions of an at least partly deformable material. The extensions engage in cutouts provided in the printed-circuit board and pass through the latter. A positive-linkage and/or frictional housing/printed-circuit board connection is established by deformation of the extensions. Further, an overvoltage protection plug for terminal blocks of the telecommunication technique with a voltage surge arrester can be mounted that combines the two functions 'earthing contact' and 'fail-safe contact' in one part.

Printed-circuit board and method for the precise assembly and soldering

A method for the protection of in particular telecommunication installations against overvoltage and overcurrent by overvoltage arresters, PTC resistors and voltage-limiting components and to a protection circuit for carrying-out the method. The object of the invention, namely to develop a method and a circuit in particular for the protection of telecommunication installations against overvoltage and overcurrent that secures a surge-current resistant and reversible line protection, is achieved by the response voltage of the overvoltage arrester being higher than the peak value of a powersupply voltage, and that the response voltage of the thyristor diodes selected being slightly above the maximum operating voltage values of the line to be protected. The PTC resistors are used as a decoupling member to block the maximum amplitudes of the power supply voltage.

Method for the protection in particular of telecommunication

The present invention relates to an air spark gap for determining the maximum voltage at an aged voltage surge suppressor (5) comprising an electrode arrangement in a capsule filled with an inert gas. The voltage surge suppressor is disposed in a voltage surge protection plug. The air spark gap is disposed between two contact members (2, 3 or 4, resp.) parallel to the voltage surge suppressor. The one (2) of the contact members is electrically connected with a contact element (7) resting, in the plugged-on condition of the voltage surge protection plug, resiliently on a surface portion against the other one (3, 4) of the contact members. For an electrical disconnection, an electrical insulation foil (8, 9) having a given thickness is arranged between the contact element and the other one of the contact members, said electrical insulation foil being provided with an opening for forming an air gap therebetween.
