Today, I will introduce a national invention authorized patent-an IC card gas meter and its controller. The patent was applied for by Sichuan Haili Intelligent Technology Co., Ltd., and the authorization was announced on March 22, 2017.
Content descriptionThe utility model relates to the technical field of gas meters, in particular to an IC card gas meter and its controller.
Background of the inventionThe IC gas meter is a smart gas meter that can insert an IC card. The existing card inserting methods are mainly divided into positive inserting and side inserting. Positive inserting means inserting the card vertically on the front of the case, and side inserting means inserting the card on the side of the case. Insert the card. If a positive plug-in design method is adopted, then, due to the limitations of the plug-in method, the controller board inside the controller box often needs to be divided into two or more pieces, and the different boards need to be connected by connecting wires. Therefore, the The design method will increase the cost, increase the point of failure, cause the controller to run unstable, and it is not easy to install and arrange. If the side-insertion design is adopted, it is inconvenient to insert the card, the seal at the bayonet is not easy to solve, and water vapor can easily enter the inside of the controller box from here, causing internal corrosion, which is prone to failure.
Therefore, how to solve the problems of difficulty in card structure arrangement and unsafe use of the IC card gas meter is a technical problem that needs to be solved by those skilled in the art at present.
Summary of the inventionIn view of this, the purpose of the present invention is to provide an IC card gas meter controller. The controller has a simple structure layout, is convenient for card insertion, and is safe to use. Another object of the present invention is to provide an IC card gas meter including the controller.
In order to achieve the above objective, the present invention provides the following technical solutions: an IC card gas meter controller, including a controller box and a controller board located inside the controller box, the controller box includes a controller base And a controller upper cover assembly, the controller upper cover assembly includes a controller upper cover and a battery compartment cover, the battery compartment on the front of the controller upper cover is provided with a card slot, and the opening of the card slot faces the Obliquely below the controller box, the outer side of the controller upper cover is provided with the openable and closable battery compartment cover covering the card slot, the controller board is fixed on the controller base, and the control A card socket is fixed on the device board, the card socket is directly opposite to the card socket on the controller board, and the controller board is arranged obliquely with respect to the vertical bottom surface of the controller base. The holder is welded and fixed on the controller board. An annular sealing ring is provided on the edge of the battery compartment of the upper cover of the controller.
The IC card gas meter controller provided by the utility model includes a controller box and a controller board located inside the controller box. The controller box includes a controller base and a controller upper cover assembly, and the controller upper cover assembly includes a controller The upper cover and the battery compartment cover. The battery compartment on the front of the controller upper cover is provided with a card slot. The opening of the card slot faces the obliquely lower part of the controller box. The outer side of the controller upper cover is provided with an openable and closable card covering the card slot. The battery compartment cover, the controller board is fixed on the controller base, the controller board is fixed with a card socket, the card slot is directly opposite to the card socket on the controller board, and the controller board is arranged obliquely with respect to the vertical bottom surface of the controller base.
This solution integrates the controller board and the card holder into a whole, with a compact structure, which is convenient for board layout design, and eliminates the need for connecting wires, reduces the point of failure, and the controller runs more stable and safer; the controller board is tilted relative to the controller base The arrangement can reduce the overall thickness of the gas meter; the card insertion port is arranged on the front of the upper cover of the controller and the opening is directed obliquely downward, which can make the card insertion operation more convenient and also facilitate the sealing treatment at the card insertion port. The utility model increases the reliability of the controller, reduces the failure rate, and has the advantages of compact structure, convenient operation and high reliability.
The utility model also provides an IC card gas meter including the above-mentioned controller. The derivation process of the beneficial effects produced by the IC card gas meter is roughly similar to the derivation process of the beneficial effects brought about by the above-mentioned controller, so it will not be repeated here.
Waterproof Vertical Mount D-Sub Connectors
waterproof D-sub system is IP67 rated. These panel-mount connectors are available in solder cup as well as right angle and vertical PCB mount types. The cable-mount connector kit includes the connector, which has solder cup contacts. These connectors are available in 9-, 15-, and 25-positions in standard density and 15-, 26-, and 44-positions in high density. The recommended wire gauge for the solder cup connector is 22 AWG to 26 AWG.
These panel-mount waterproof D-subs are designed for rear-mount applications in panels that are up to 2.0 mm thick. They come with two sets of jackscrews. One jackscrew set is 5 mm long for panel thickness up to 1.2 mm, and the other is 6 mm long for panel thicknesses from 1.2 mm to 2.0 mm.
Cable mount D-sub connector kits come with the backshell, seal, thumbscrews, and solder cup connector. They are also easy to install. Simply fit the cable through the backshell, terminate the wire to the solder cup contacts, and hand tighten the cable nut on the rear of the backshell. The backshell will seal a particular range of cable diameters depending on the position count of the connector. Consult the datasheet for specific cable diameter ranges.
