Abstract
The invention relates to an overvoltage protection magazine for a telecommunications device, comprising a housing, a printed circuit board, two or more surge arresters and at least one ground contact, the surge arresters being arranged on the printed circuit board and being passed via conductor tracks to contact pads arranged on the printed circuit board which, when plugged in, come into electrical contact with contacts of the telecommunications device, the surge arresters being arranged in a row.
Claims14
An overvoltage protection magazine for a telecommunication device, comprising:
- a housing having a top and a bottom, wherein the housing is integral, wherein the housing is open at the top and covered by an insulator strip, wherein inner sides of the housing are provided with supports for the insulator strip, wherein the housing is provided with a slot on at least one of end sides of the housing by means of which the insulator strip is configured to be levered out using a tool;
- a printed circuit board arranged within the housing, the printed circuit board having a top, a bottom, a front, and a rear, the printed circuit board defining ground contact pads on opposite sides of the printed circuit board at the top of the printed circuit board, each of the ground contact pads extending from the front to the rear of the printed circuit board;
- at least three adjacent surge arresters arranged on the printed circuit board in a single row, each surge arrester including a first outer electrode, a second outer electrode, and a center electrode, the center electrode of each surge arrester being electrically coupled to the ground contact pads via a conductor track on the printed circuit board;
- and
- at least one ground contact in the form of a forked contact coupled to the housing, the ground contact being configured to mate to at least one of the ground contact pads of the printed circuit board;
- wherein a lower region of the printed circuit board defines cutouts that form plug-in regions corresponding to the surge arresters, wherein the outer electrodes of the surge arresters are associated with the corresponding plug-in region via conductor tracks on the printed circuit board, wherein each plug-in region includes a contact pad for each outer electrode of the corresponding surge arrester, each contact pad being arranged on the front and rear of the printed circuit board.

An overvoltage protection magazine for a telecommunication device, the overvoltage protection magazine comprising:
- a printed circuit board extending from a first end to a second end and having a front and a rear, the first end forming separate plug-in regions, each plug-in region defining a first contact pad and a second contact pad on the front of the printed circuit board and defining a first contact pad and a second contact pad on the rear of the printed circuit board, the second end of the printed circuit board defining a first ground contact pad at a first side and a second ground contact pad at an opposite, second side;
- a plurality of surge arresters mounted to the printed circuit board in a single row at the second end of the printed circuit board, each surge arrester including first and second outer electrodes that couple to the first and second contact pads, respectively, of a corresponding one of the plug-in regions;
- an integral housing defining an interior configured to receive the printed circuit board with the surge arresters, the integral housing having a first side defining a plurality of openings configured to receive the plug-in regions of the printed circuit board, the first side of the integral housing also including closed webs arranged to extend between the plug-in regions when the printed circuit board is arranged within the integral housing and slotted webs arranged to extend over the plug-in regions when the printed circuit board is arranged within the integral housing, wherein the integral housing defines a second side covered by an insulator strip, wherein inner sides of the housing are provided with supports for the insulator strip, wherein the housing is provided with a slot on at least one of end sides of the housing by means of which the insulator strip is configured to be levered out using a tool;
- and
- at least one ground contact in the form of a forked contact coupled to the housing, the ground contact being configured to mate to at least one of the ground contact pads of the printed circuit board.
