PL70167Y1 - Plated coating of a converter of current to voltage - Google Patents

Abstract

The current to voltage converter plate, made in the form of a printed circuit board, with evenly milled slots around the circumference and an internal hole, containing solder pads and tracks, at each slot (2) has solder pads (1), connected with each other by tracks (3) in such a way that the connections run around the milled hole (7), from the lead-out points (6) to the solder pads of the compensation elements (5). At every second slot (2) the solder pads (1) are short-circuited by a jumper (4).

Description

Pattern description

The subject of the utility model is the plating of the current-to-voltage converter.

Current-to-voltage converters, made in PCB technology, are made of sensor elements, which are most often multilayer air coils, and a plating, i.e. a single- or multi-layer printed circuit board to which the sensor elements are mechanically and electrically attached and which contains connections between these sensor elements and additional elements, such as circuits for compensation, leads, etc. The sensitivity of such a transducer depends on the number of installed and connected sensor elements. The patent application PL 398526 A1 shows a plate of a current-to-voltage converter used to establish mutual positions of the components of the converter and to make electrical connections between the components. It contains milled slots, solder pads, connections and leads. In another description of a plating plate, known from the utility model PL 064671 Y1, containing connections, solder pads and an inner hole, it is necessary to use connectors to fix the sensor elements of the transducer.

From the patent application PL 414 745 A1 a plating is known which enables the production of a transducer with switchable sensitivity. This plate also contains milled slots, pads, connections and leads.

The plate of the current-to-voltage converter according to the pattern is made in the form of a printed circuit board with slots milled evenly on the circumference and an internal hole. The plate at each slot has solder pads connected to each other by tracks in such a way that the joints run around the milled hole, from the lead points to the pads of the compensation elements, with the pads being short-circuited at every second slot.

As the transducer can be made in various sensitivity variants, all or every second sensor element can be soldered to the plate. If all sensing elements are soldered, the connections include the pads of these elements. If we want to mount every second sensor element, then in order to maintain the continuity of connections, the contact fields at every second slot, in which the sensor elements will not be mounted, are short-circuited with thin paths. If all sensing elements are mounted, the thin jumper tracks must be cut. The advantage of this solution is the possibility of changing the sensitivity by installing every second sensor element without losing the continuity of connections, and easy and cheap mounting of the sensor elements directly in the gap by soldering to the solder pads.

The object of the utility model is shown in the drawing showing the plate view of the current-to-voltage converter.

The plate of the current-to-voltage converter is made in the form of a printed circuit board with slots 4 evenly milled around the circumference and the inner hole shown by the hole milling line 7. The plate at each slot 2 has solder pads 1 connected with each other by tracks 3. Connections of tracks 3 run around the milled hole 7, from the pins 6 to the pads of the compensation elements 5. At every second gap 2, pads 1 are short-circuited with a jumper 4.
