FIG. 1B is a diagram illustrating a state in which the communication device is retracted from the base 6 and attached to the case 5 during current line connection work.

計量装置の詳細は、図16で説明したものと略同一であるので、同一部分は同一部号を付し、その説明は、以後省略する。通信装置の詳細は、図17で説明したものと略同一であるので、同一部分は同一部号を付し、その説明は、以後省略する。   Since the details of the weighing device are substantially the same as those described in FIG. 16, the same parts are denoted by the same reference numerals, and the description thereof will be omitted. The details of the communication apparatus are substantially the same as those described with reference to FIG. 17, and thus the same parts are denoted by the same reference numerals, and the description thereof will be omitted.

通信装置には、図17に示すように、計量装置のベース6に取り付けるため、計量装置取付部13aが下ケース13に形成されている。この計量装置取付部13aには、突起部130とその周囲に溝部131が形成されている。   As shown in FIG. 17, the communication device has a weighing device attachment portion 13 a formed in the lower case 13 for attachment to the base 6 of the weighing device. The weighing device mounting portion 13a has a projection portion 130 and a groove portion 131 formed around it.

計量装置は、図16に示すように、通信装置をベース6に取り付けるため、通信装置の計量装置取付部13aに嵌合する通信装置取付部6b(本発明の第1の通信装置取付部に対応)がベース6に形成されている。この通信装置取付部6bには、突起部130と嵌合する溝部60が形成されている。   As shown in FIG. 16, the weighing device is attached to the base 6 so that the communication device is attached to the weighing device attachment portion 13a of the communication device (corresponding to the first communication device attachment portion of the present invention). ) Is formed on the base 6. The communication device mounting portion 6b is formed with a groove portion 60 that fits with the protruding portion 130.

また、計量装置において、図1(a)に示すように、通信装置取付部6bがあるベースとは異なる位置、即ち、ケース5に通信装置取付部5a(本発明の第2の通信装置取付部に対応)が形成されている。この通信装置取付部5aには、突起部130と嵌合する溝部50が形成されている。   In the weighing device, as shown in FIG. 1A, the communication device mounting portion 6b is located at a position different from the base, that is, the case 5 and the communication device mounting portion 5a (the second communication device mounting portion of the present invention).

In the watt-hour meter of the first embodiment, as shown in FIG. 1A, the communication device mounting portion 5 a of the metering device is disposed at the lower left end of the case 5, and the groove portion 50 is substantially parallel to the surface of the case 5. Since it is formed in the direction, as shown in FIG. 1B, the communication device is installed at a substantially right angle with respect to the case 5 of the weighing device in the state where the communication device is attached when the current line is connected.

これに対して、実施例1の変形例では、図2(a)に示すように、計量装置の通信装置取付部5bをケース5の略中央左側に配置し、且つ溝部51をケース5の表面に略直角になる方向に形成したので、計量装置取付部13aに形成された突起部130をケース5に形成された溝部51に嵌合させて、ケース5に通信装置を取り付けると、図2(b)に示すように、電流線接続作業時の通信装置取り付け状態は、通信装置が計量装置のケース5に対して略平行に配置される。   On the other hand, in the modified example of the first embodiment, as shown in FIG. 2A, the communication device mounting portion 5b of the weighing device is disposed on the substantially central left side of the case 5, and the groove portion 51 is provided on the surface of the case 5.

FIG. 4A is a diagram showing an assembled watt hour meter with the communication device attached to the base 6 with the cover 7 of the metering device removed. FIG. 4B is a diagram illustrating a state in which the communication device is retracted from the current line mounting screw 2 during the current line connection work.

この通信装置には、実施例1同様に、電力量計として通信装置を計量装置に取り付ける電力量計組立時に、通信装置をベース6に取り付けるため、下ケース13に計量装置取付部13a(本発明の第1の計量装置取付部に対応)、突起部130、周囲の溝部131が形成されている。   In this communication device, as in the first embodiment, a metering device mounting portion 13a (the present invention) is attached to the lower case 13 in order to attach the communication device to the base 6 when the watthour meter is mounted. Corresponding to the first weighing device mounting portion), a protrusion 130 and a surrounding groove 131 are formed.

また、計量装置取付部13aとは別に、通信装置の上ケース12に計量装置取付部12b、突起部120、周囲の溝部121が形成されている。   In addition to the weighing device mounting portion 13a, a weighing device mounting portion 12b, a protrusion 120, and a surrounding groove 121 are formed in the upper case 12 of the communication device.

このように構成された実施例2の変形例に係る電力量計によれば、電力量計として通信装置を計量装置に取り付ける電力量計組立時においては、図4(a)に示すように、通信装置の計量装置取付部13aに形成された突起部130を、計量装置のベース6に形成された溝部60に嵌合させて、ベース6に通信装置を取り付けられる。   According to the watt-hour meter according to the modification of the second embodiment configured as described above, at the time of assembly of the watt-hour meter in which the communication device is attached to the weighing device as the watt-hour meter, as shown in FIG.
