With the improvement of living standards and the strengthening of environmental protection awareness, people’s daily cooking fuel has been converted from wasteful resources such as wood and coal, and serious pollution of conventional energy sources to the use of natural gas and gas, and even electricity and other clean energy. The gas meter will play its role here. With its automatic accumulation function, those who use natural gas or pipeline gas can easily know how much gas they use so that they can pay according to the cubic meters of gas consumed per month. .

Gas meters are generally installed in the kitchen or cabinet, but the environment is generally relatively humid, so a certain waterproof function is required. In the prior art, the diaphragm of the gas meter is generally directly fixed to the gas meter through a fixed sleeve. On the upper side, gaps are easily formed between the fixed sleeve and the diaphragm and between the outside of the diaphragm gas meter. Water or vapor can enter through these gaps and adhere to the inner side of the gas meter. Long-term adhesion may cause the diaphragm to be unclear. And in the kitchen environment, the water contains acid, greasy, etc., which not only forms stains, but may also cause corrosion to the inside of the instrument.

The technical problem to be solved by the utility model is to overcome the existing technical defects and provide a waterproof seamless connection type gas meter diaphragm device with good sealing effect, good waterproof function and high structural strength.

The picture shows the structure diagram of the utility model

The technical problem to be solved by the utility model is realized by adopting the following technical solutions: a waterproof seamless connection type gas meter diaphragm device, which is characterized in that it includes a diaphragm body, and a diaphragm is arranged on the front side of the diaphragm body In the observation area, the outer edge of the rear side of the diaphragm body is provided with an outer fold, the rear side of the diaphragm body is provided with an inner fold on the inner side of the outer fold, and an inner fold is provided between the inner fold and the outer fold. In the partition groove, the back side of the diaphragm body and the inside of the partition groove are uniformly provided with bayonet pins, and the inner edge of the outer flange is provided with a flat flange that is bent outward.

The inner side of the flat folded edge is provided with waterproof grooves. The diaphragm body is an integral structure of injection molding. An adhesive layer is arranged inside the compartment. The inner height of the outer flange is higher than the inner height of the inner flange.

The beneficial effects of the utility model are: the utility model has good sealing effect, good waterproof function, high structural strength, no pollution to the instrument, and high safety.

IDC D-Sub Connectors

IDC D-sub Connectors

IDC (insulation displacement contact) D-sub connectors are a type of electrical connectorthat's designed to be connected to the conductor(s) of an insulated cable, most commonly a ribbon cable(a cable with many conducting wires running parallel to each other on the same flat plane).

Applications for IDC D-sub connectors

IDC D-sub connectors, attached to ribbon cables, are helpful in situations where you need to make a lot of connections without a big number of wires. They're commonly used in computer and electronic systems that require multiple data buses to link internal peripherals, such as disk drives to their drive controllers. They're also frequently used in industrial and telecom applications.

How does an IDC D-sub connector work?

With an IDC D-sub connector, there's no need for cable preparation – in other words, you don't need the strip the cables of their insulation before connecting. To connect the cable to the connector, there are sharpened blades (or contacts) on the connector that force through the insulation around the cable, making a secure connection.

IDC D sub connector from Antenk, Outstanding features high contact reliability, long life and low contact resistance.
