[0020] The present invention will be further described below by way of embodiments and in conjunction with the accompanying drawings:

[0021] like Figure 1 to Figure 7 As shown, a housing of a large-caliber water meter remote transmission terminal device includes a chip compartment 1 and a battery compartment 2 arranged adjacent to each other above and below, and the chip compartment 1 and the battery compartment 2 each include a bottom plate b and a cover a covering the bottom plate b. A mounting skirt extends outwardly from the opening of the cover a in the circumferential direction, and the mounting skirt is flush with the outer edge of the bottom plate b and is connected by a bolt assembly to form a shell. A ring groove e for mounting a sealing ring is provided on one side of the mounting skirt for abutting against the bottom plate b, and a circle of pressing ridges b is also convexly provided on the bottom plate b corresponding to the ring groove e, which can press the sealing ring by pressing the ridges b to provide sealing.

[0022] The front side wall of the cover a of this embodiment is provided with wiring holes d, and the wiring holes d are equipped with cable waterproof connectors. The number of wiring holes d in the chip compartment 1 is greater than the number of wiring holes d in the battery compartment 2, which meets the installation requirements for the output and input lines of the chip. The wiring holes d are all arranged on the same side of the chip compartment 1 and the battery compartment 2 (both are arranged on the front side wall). It is convenient for installation. Of course, in the actual process, the position and number of the wiring holes d can be set according to the specific wiring requirements. The wiring holes d on the chip compartment 1 and the battery compartment 2 can also be set on different sides.
