FIG. 4 is a Wi-Fi unit of the used power measuring device according to the embodiment of the present invention.

The power consumption measuring apparatus 1 according to the present embodiment has a Wi-Fi communication function, and is mainly composed of a Wi-Fi unit 3, a substrate unit 6, and a resin design cover 2. The Wi-Fi unit 3 includes a Wi-Fi communication unit 4 having a radio wave transmission unit 12 and a Wi-Fi communication unit fixing unit 5, and the substrate unit 6 includes a substrate 7, a metal substrate part case 8, and a metal. It is comprised with the board | substrate part cover 9. FIG.
Although not shown, power is distributed from the distribution board to each electric device, and the power is branched to the used power measuring device 1 by branching on the way. Data (power amount) calculated by an IC (for example, a microcomputer) mounted on the substrate 7 of the substrate unit 6 is provided to the user from the Wi-Fi communication unit 4 of the Wi-Fi unit 3 through an interface such as a tablet. The

As shown in FIG. 3, the substrate unit 6 is housed in a metal substrate portion case 8 so that it does not spread when a fire occurs due to a short circuit of the substrate 7, and the front side is covered with a metal substrate portion cover 9. It is constituted by. A plurality of screw holes 13 (for example, two locations) are provided on one side surface (hereinafter referred to as an upper side surface) of the metal substrate case 8 in the longitudinal direction.
As shown in FIG. 4, the Wi-Fi unit 3 is configured such that a rear part of the Wi-Fi communication unit 4 is accommodated in a Wi-Fi communication unit fixing unit 5. Moreover, the Wi-Fi communication part 4 has the radio wave transmission part 12 ahead, and the Wi-Fi unit 3 has a shape in which the radio wave transmission part 12 protrudes forward. A plurality of screw holes 13 (for example, two locations) are provided on one side surface (hereinafter referred to as a lower side surface) of the Wi-Fi communication unit fixing unit 5 in the short direction.

FIG. 5 is an exploded perspective view of the power consumption measuring apparatus according to the embodiment of the present invention.
As shown in FIG. 5, the power consumption measuring apparatus 1 is configured such that the Wi-Fi unit 3 is disposed on the upper side of the substrate unit 6 and the resin design cover 2 is attached to the front surface thereof.

FIG. 6 is a rear view illustrating a method of fixing the Wi-Fi unit and the substrate unit of the power usage measuring apparatus according to the embodiment of the present invention.
The screw hole 13 provided on the upper side surface of the metal substrate unit case 8 and the lower side surface of the Wi-Fi communication unit fixing unit 5 makes the Wi-Fi unit 3 adjacent to the upper side of the substrate unit 6 as shown in FIG. And when the front side of the Wi-Fi communication part 4 and the metal board | substrate part cover 9 are arrange | positioned toward the same direction, it is provided in the position which mutually overlaps.

The substrate unit 6 and the Wi-Fi unit 3 are built in the power consumption measuring apparatus 1. At this time, the Wi-Fi unit 3 is fixed by screws 10 in a state where the Wi-Fi unit 3 is adjacent to the upper side of the board unit 6, and the radio wave transmission unit 12 of the Wi-Fi communication unit 4 is The Wi-Fi unit 3 and the substrate unit 6 are incorporated in a state of being arranged in an inverted L shape protruding forward from the substrate unit 6.
Here, the radio wave in Wi-Fi communication flies radially from the radio wave transmission unit 12 to the front, upper, and lower sides. There is a possibility that a part of the radio wave that flies downward is blocked and the transmission performance of Wi-Fi communication is lowered. The same applies to the reception performance.
Therefore, by arranging the Wi-Fi unit 3 and the substrate unit 6 so that the radio wave transmission unit 12 as described above has an inverted L shape protruding forward from the substrate unit 6, not only the front and the upper side. The lower radio wave can also be transmitted and received efficiently.

The Wi-Fi unit 3 needs to be covered with a cover like the substrate unit 6 in order to protect the radio wave transmission unit 12 of the Wi-Fi communication unit 4. However, if it is covered with a metallic cover like the substrate unit 6, the radio waves transmitted and received from the radio wave transmission unit 12 are blocked. Therefore, it is necessary to cover with a resin cover which is made of non-metal.
At this time, if only the radio wave transmission part 12 of the Wi-Fi unit 3 is covered with a resin cover, the boundary between the resin part of the Wi-Fi unit 3 and the metal part of the substrate unit 6 is visible in appearance, The design of the entire device is not uniform, and the design is impaired.
Therefore, as shown in FIGS. 1 and 2, the resin design cover 2 integrally covers the radio wave transmitter 12 of the Wi-Fi unit 3 and the front of the substrate unit 6.

FIG. 7 is a side view of the power usage measuring apparatus according to the embodiment of the present invention with the resin design cover removed.
The resin design cover 2 is a resin cover, and corresponds to the inverted L-shape formed by the Wi-Fi unit 3 and the substrate unit 6, and in the state viewed from the side as shown in FIG. The Fi unit 3 side) is configured to be wider than the lower side (substrate unit 6 side), and the front surface is formed in an arc shape that gently protrudes from the lower side to the upper side.
An insertion part 11 is provided on the upper rear side of the resin design cover 2, and the insertion part 11 is attached by being inserted into an insertion port (not shown) provided on the upper side of the Wi-Fi communication part fixing part 5. .

  As described above, communication is performed by arranging the Wi-Fi unit 3 and the substrate unit 6 so that the radio wave transmission unit 12 of the Wi-Fi communication unit 4 has an inverted L shape protruding forward from the substrate unit 6. While maintaining the performance, the resin design cover 2 integrally covers the radio wave transmission part 12 of the Wi-Fi unit 3 and the front of the substrate unit 6, so that the design of the entire device has a unified sense of design. An excellent power usage measuring device 1 can be obtained.

  In this embodiment, the communication function is Wi-Fi, but other wireless communication standards may be used. Further, the number of screw holes 13 provided on the upper side surface of the metal substrate case 8 and the lower side surface of the Wi-Fi communication unit fixing unit 5 is not limited to two, and any number that can fix each other with 10 screws.
