Wherein the sealing member 9 may be a sealing ring.

At present, with the improvement of industrial automation level, the automatic assembly line of the gas meter is widely applied in the industry, but in the process that an aviation connector inside the gas meter is led out to the outside, the aviation connector needs to be fixed by clamping equipment inside the gas meter so as to fix a metering assembly and a shell at first, then the aviation connector is fixed with an upper shell and an installation part, then a shell card and a sealing element are placed, and finally the upper shell is placed on the shell card and the shell is assembled in sequence. When the aerial connector is fixed to the mounting portion, a clamping device is required, and for convenience of operation, a long cable is generally used for connecting the metering assembly with the aerial connector. Therefore, after the aviation connector is fixed with the upper shell and the installation part, when the aviation connector is installed, the phenomenon that the cable is hung upside down on the upper shell can be formed, and therefore, the cable is inconvenient to fix due to the overlong length and is easy to press the cable in the subsequent assembly process, and automation of the process is not achieved.

According to the gas meter with the clamping portion 40, clamping equipment is not needed for fixing the plug connector 5, after the plug connector 5 is clamped in the clamping portion 40, the shell card, the sealing element and the upper shell 11 are placed together for sealing, and the plug connector 5 is fixedly connected with the upper shell 11 and the mounting portion 6 after the shell is sealed. Because do not need the fixed of centre gripping equipment, be convenient for arrange in order the cable after 5 cards of plug connector are established in joint portion 40, place the shell card after arranging the cable in order, the sealing member, epitheca and enclosure, thereby avoid the gas table to be pressed the line in assembling process, the casing 10 of being convenient for takes the measurement subassembly 30 to flow in producing the line, be convenient for automatic, and avoided earlier fixed with epitheca 11 and installation department 5 of plug connector, drag the cable when installing shell card and sealing member again and lead to the possibility of being connected failure between plug connector 5 and the measurement subassembly 30.

And in one embodiment, in order to further facilitate the arrangement and fixation of the cables, a fixing buckle is further arranged in the housing 10. After the aviation connector is clamped in the clamping portion 40, the fixing buckle can fix the cable on the shell 10, and the cable can be further prevented from being pressed in the subsequent assembling process. Furthermore, no clamping device is required, so that shorter cables can be used to connect the metering assembly with the aerial connector, saving production costs.
