TH20963A - Connections using ZebraStream - Google Patents

Abstract

This invention relates to a housing for a price display device consisting of an LCD (30) and a printed circuit board (20) with an electronic control unit and a power supply such as a solar cell, etc. The thin LCD (30) is connected to the underlying printed circuit board (30) by means of a junction device with an area of inductive rubber. Such device is a zebra contact or zebra contact strip (15) which is located between the LCD (30) and the printed circuit board by means of an outer junction (12a, 12b) on the printed housing (10). In a good form, it is made of an outer junction material (12a, 12b) which under manufacturing is specified to have an inward tensile force.

Claims (10)

1. Methods of connecting to a price display device (1) which consists of an LCD (30) and a printed circuit board (20) with an electronic control unit and feedback unit such as a solar cell. For the connection of the thin LCD (30) to the underlying printed circuit board (30) by means of an inductive rubber junction in the form of a zebra junction (15) which is characterized as follows: The zebra junction (15) in the direction across the inductive rubber is pressed between the LCD (30) and the printed circuit board by means of a casing (10) which in good form is made of a plastic material. The front edges of the casing (12a, 12b) are partially stretched during fabrication or manufacturing. There are at least two parallel longitudinal edges (12a, 12b) of the casing designed and fabricated with a material that will be stretched in such a way that the centered front edges of the casing overlap. The center of the zebra contact (15) along the matching edges of the LCD (30) and printed circuit board (20) contains the connectors (21,22) for signal transmission between the LCD and printed circuit board. The underside acts as a pressure beam against the glass (33) that makes up the front part of the LCD, where at least 15% of the inductive rubber of the zebra connector (15) is compressed. 2. The method specified in claim 1, in which the enclosure (10) shall at least have a cut groove (14a, 14b) along the long edge to reinforce the plastic or metal parts. 3. The method specified in Claim 1, where the longitudinally parallel outer edges (12a, 12b) of the enclosure (10) shall be fitted with an inner groove that fits into a thin interlocking groove (13a, 13b) for a label containing material information and be inserted under the center-oriented portion of the outer enclosure of the product price indicator. 4. The method specified in Reputation 1 in which the tensile force of the outer cladding (12a, 12b) is obtained by means of the outer cladding (12a, 12b) under casting being slightly inwardly sloped toward the rear of the cladding (10). 5. The method specified in any of the claims above, where the front glass (33) of such LCD, with the connectors for the electrical connection of the LCD, is wide, where the rear glass (32) and the component arrangement, along with the mounting brackets for the zebra connector strip (15), are located along the top and/or bottom edges of the rear glass (32). 6. The arrangement of the price display device (1) consists of an LCD (30) and a printed circuit board (20) with an electronic control unit and a power supply unit, namely a solar cell. The thin LCD (30) is connected to the underlying printed circuit board (30) by means of a zebra junction (15), in which the zebra junction (15) in the longitudinal direction of the zebra junction area is compressed between the LCD (30) and the printed circuit board by means of the outer edges (12a, 12b) of the enclosure (10) which are well made of plastic material and in which the edges (12a, 12b) under the printing process are compressed inward. At least, there are parallel outer edges in the longitudinal direction (12a, 12b) of the enclosure which are designed and constructed with compressive material in such a way that its inner front edge is centered. Located above the center of the zebra contact (15), along the matching edges of the LCD (30) and the printed circuit board (20), which contain the connectors (21,22) for signal transmission between the LCD and the underlying printed circuit board, it acts as a pressure beam against the glass (33) that makes up the front of the LCD, where these edges apply a pressure of at least 15% of the inductive rubber of the zebra contact (15). 7. The placement of devices for price display devices as specified in claim 6, where the printed cover (10) shall have at least a few cut grooves (14a, 14b) along the long edges to reinforce the plastic or sheet metal parts. 8. The placement of the price display device as specified in claim 7, where the longitudinally parallel outer edges (12a, 12b) of the molded enclosure (10) have an inner groove that forms a thin interlocking groove (13a, 13b) for the label containing the item information and is inserted under the outer enclosure portion facing the center of the price display device. 9. The placement of the device as specified in claim 8, whereby the outer edges of the enclosure (12a, 12b) under the printing are slightly beveled inward toward the rear of the enclosure (10). 10. Device placement as specified in any of the claims above, from clauses 6 through 9, where the front glass (33) of the LCD with the connectors for the LCD's electronic connections is wide, whereby the rear glass (32), device placement and the zebra touch strip mounting bracket (15) are located along the top and/or bottom edges of the rear glass (32).
