However, the definitions of upper, lower, front, rear, right side, and left side are provided merely for the convenience of explanation, and these definitions of directions are not intended to limit the orientation of the communication device and bushing of the present invention during use or assembly.

[0012] First, a communication device 100 according to this embodiment will be described with reference to Fig. 1. Fig. 1 is a front view showing the communication device 100 according to this embodiment. The communication device 100 transmits information indicating measurement results of a measuring device relating to resources or energy. Specifically, the communication device 100 transmits the information indicating the measurement results by wireless communication. For example, the communication device 100 transmits the information indicating the measurement results to a center that collects the measurement results.

[0013] The resource or energy is, for example, gas, electricity, or water. The measuring device is, for example, a gas meter, an electricity meter, or a water meter. The gas meter measures the amount of gas used. The electricity meter measures the amount of electricity used. The water meter measures the amount of water used.

[0014] The communication device 100 receives a signal indicating a measurement result from the measurement device and acquires information indicating the measurement result. For example, the communication device 100 is connected to the measurement device by wire and receives a signal indicating the measurement result from the measurement device. Specifically, the communication device 100 may be electrically connected to the measurement device via a cable member CA (see FIG. 13).

[0015] As shown in FIG. 1, the communication device 100 includes a housing 1. The housing 1 is box-shaped and seals the internal space. In this embodiment, the housing 1 includes a case member 2 and a cover member 3. The cover member 3 is detachably attached to the case member 2. When the cover member 3 is attached to the case member 2, the internal space of the housing 1 is sealed.

[0016] Next, the case member 2 and the cover member 3 will be described with reference to Figures 2 and 3. Figure 2 is a side view showing the case member 2 and the cover member 3. Figure 3 is a front view showing the case member 2 and the cover member 3. In detail, Figures 2 and 3 show the housing 1 in a state where the cover member 3 has been removed from the case member 2.

[0017] As shown in FIG. 2 , the case member 2 has a front wall portion 21, an upper wall portion 22, and a rear wall portion 23. The front wall portion 21 faces the upper portion of the rear wall portion 23 in the front-to-rear direction. The front of the lower portion of the rear wall portion 23 of the case member 2 is open. Therefore, the case member 2 has an opening 2A in the lower portion of the front face. The front wall portion 21 of the case member 2 forms the front wall of the upper portion of the housing 1. The upper wall portion 22 of the case member 2 forms the upper wall of the housing 1. The rear wall portion 23 of the case member 2 forms the rear wall of the housing 1.

[0018] As shown in FIG. 2, the cover member 3 has a front wall portion 31 and a lower wall portion 32. The front wall portion 31 of the cover member 3 forms the front wall of the lower part of the housing 1. The lower wall portion 32 of the cover member 3 forms the lower wall of the housing 1. The rear side of the cover member 3 is open. When the cover member 3 is attached to the case member 2, the opening 2A of the case member 2 is covered by the cover member 3, and the front wall portion 31 of the cover member 3 faces the lower part of the rear wall portion 23 of the case member 2.

[0019] As shown in FIG. 3 , the case member 2 has a right wall portion 24 and a left wall portion 25. The cover member 3 has a right wall portion 33 and a left wall portion 34. The right wall portion 24 of the case member 2 forms the right wall of the upper part of the housing 1. The left wall portion 25 of the case member 2 forms the left wall of the upper part of the housing 1. The right wall portion 33 of the cover member 3 forms the right wall of the lower part of the housing 1. The left wall portion 34 of the cover member 3 forms the left wall of the lower part of the housing 1.

[0020] Next, a communication device 100 of this embodiment will be described with reference to FIGS. 1, 2, and 3. As shown in FIGS. 1, 2, and 3, the housing 1 has a first protrusion 4 and a second protrusion 5. The first protrusion 4 protrudes upward from the top surface of the housing 1. The second protrusion 5 protrudes downward from the bottom surface of the housing 1. Specifically, as shown in FIGS. 2 and 3, the first protrusion 4 and the second protrusion 5 are provided on the case member 2. More specifically, the first protrusion 4 protrudes upward from the top end of the rear wall 23 of the case member 2. The second protrusion 5 protrudes downward from the bottom end of the rear wall 23 of the case member 2.

[0021] Next, the communication device 100 of this embodiment will be further described with reference to Fig. 1. As shown in Fig. 1, the housing 1 has a first insertion hole 6a, a second insertion hole 6b, a third insertion hole 7a, a fourth insertion hole 7b, a fifth insertion hole 7c, a sixth insertion hole 7d, a seventh insertion hole 8a, and an eighth insertion hole 8b.

[0022] The first insertion hole 6a and the second insertion hole 6b penetrate the housing 1 in the front-rear direction. Specifically, the first insertion hole 6a and the second insertion hole 6b are provided in the upper wall portion 22 (see FIG. 2) of the case member 2 and penetrate the upper wall portion 22 (see FIG. 2) of the case member 2 in the front-rear direction. The first insertion hole 6a and the second insertion hole 6b are arranged side by side in the left-right direction.

[0023] The third insertion hole 7a and the fourth insertion hole 7b are provided in the first protruding portion 4 and penetrate the first protruding portion 4 in the front-rear direction. The third insertion hole 7a and the fourth insertion hole 7b are arranged side by side in the left-right direction.

[0024] The fifth insertion hole 7c and the sixth insertion hole 7d are provided in the second protruding portion 5 and penetrate the second protruding portion 5 in the front-rear direction. The fifth insertion hole 7c and the sixth insertion hole 7d are arranged side by side in the left-right direction.

[0025] The seventh insertion hole 8a is provided in the first protruding portion 4 and penetrates the first protruding portion 4 in the front-rear direction. The seventh insertion hole 8a is located between the third insertion hole 7a and the fourth insertion hole 7b.

[0026] The eighth insertion hole 8b is provided in the second protruding portion 5 and penetrates the second protruding portion 5 in the front-rear direction. The eighth insertion hole 8b is located between the fifth insertion hole 7c and the sixth insertion hole 7d.

[0027] Next, the communication device 100 of this embodiment will be described with reference to Figures 4 and 5. Figure 4 is a side view showing the communication device 100 of this embodiment. Figure 5 is a perspective view showing the communication device 100 of this embodiment.

[0028] 4, the first protrusion 4 has a front surface 4a and a rear surface 4b. The rear wall 23 of the case member 2 has a rear surface 23b. The second protrusion 5 has a rear surface 5b. The rear surface 4b of the first protrusion 4, the rear surface 23b of the rear wall 23, and the rear surface 5b of the second protrusion 5 form the rear surface (back surface) of the housing 1.

[0029] 5, the upper wall portion 22 of the case member 2 has an upper surface 22a. The upper surface 22a is located forward of the front surface 4a of the first protrusion 4. The upper surface 22a of the upper wall portion 22 forms the upper surface of the housing 1.

[0030] Next, the communication device 100 of this embodiment will be described with reference to Fig. 6. Fig. 6 is a front view showing the communication device 100 attached to a horizontal pipe P1. As shown in Fig. 6, the housing 1 can be placed on the horizontal pipe P1. The horizontal pipe P1 is a pipe extending along the horizontal direction. In this embodiment, the horizontal pipe P1 extends along the left-right direction.

[0031] The horizontal pipe P1 is a pipe for supplying resources or energy. The horizontal pipe P1 is, for example, a gas pipe, an electric pipe, or a water pipe. A gas pipe circulates gas. More specifically, gas circulates inside a gas pipe. An electric pipe houses electric wires inside. A water pipe circulates tap water.

[0032] When the housing 1 is disposed on the horizontal pipe P1, the first bundling member BA1 and the second bundling member BA2 are inserted into the first insertion hole 6a and the second insertion hole 6b, respectively, and the first bundling member BA1 and the second bundling member BA2 bundle the horizontal pipe P1 to the housing 1. The first bundling member BA1 and the second bundling member BA2 are, for example, cable ties such as insulation locks.

[0033] When the housing 1 is placed on the horizontal pipe P1, the front surface 4a of the first protrusion 4 described with reference to Figures 4 and 5 abuts against the rear portion of the horizontal pipe P1. Also, the upper surface of the housing 1 (upper surface 22a of the upper wall portion 22) described with reference to Figure 5 abuts against the lower portion of the horizontal pipe P1 in front of the first protrusion 4. In other words, the front surface 4a of the first protrusion 4 includes an abutment portion that abuts against the rear portion of the horizontal pipe P1, and the upper surface of the housing 1 includes an abutment portion that abuts against the lower portion of the horizontal pipe P1.

[0034] 1 to 6, according to this embodiment, the horizontal pipe P1 can be arranged on the top surface of the housing 1. Therefore, compared to a configuration in which the horizontal pipe P1 is arranged on the back surface (rear surface) of the housing 1, when the housing 1 (communication device 100) is attached to the horizontal pipe P1 in a vertical orientation, the center of gravity G of the communication device 100 does not deviate significantly from vertically below the center C of the horizontal pipe P1, which makes it possible to prevent the housing 1 (communication device 100) from being installed at an angle relative to the vertical direction. Therefore, compared to a configuration in which the horizontal pipe P1 is arranged on the back surface (rear surface) of the housing 1, the waterproof function is more easily maintained.

[0035] Next, the communication device 100 of this embodiment will be described with reference to Fig. 7. Fig. 7 is a side view showing the communication device 100 attached to a horizontal pipe P1. As shown in Fig. 7, in the communication device 100 of this embodiment, the front surface 4a of the first protrusion 4 and the upper surface of the housing 1 (upper surface 22a of the upper wall portion 22) have a structure that allows the center of gravity G of the communication device 100 and the center C of the horizontal pipe P1 to be arranged on a straight line L along the vertical direction when the housing 1 is placed on the horizontal pipe P1. Here, the vertical direction is a direction approximately parallel to the vertical direction.

[0036] 7, in this embodiment, when the housing 1 (communication device 100) is attached to the horizontal pipe P1 in a vertical orientation, the center of gravity G of the communication device 100 is located vertically below the center C of the horizontal pipe P1, which further prevents the housing 1 (communication device 100) from being installed at an angle relative to the vertical direction. Therefore, the waterproof function is more likely to be maintained.

[0037] Furthermore, according to this embodiment, the distance r from the center C of the horizontal pipe P1 to the bottom wall of the housing 1 (the bottom wall portion 32 described with reference to FIG. 2) can be made shorter compared to a configuration in which the horizontal pipe P1 is arranged on the top surface of the first protrusion 4. Therefore, even if a torque is generated that rotates the housing 1 (communication device 100) around the horizontal pipe P1 as its central axis, the torque is smaller compared to a configuration in which the horizontal pipe P1 is arranged on the top surface of the first protrusion 4. Therefore, even if a torque is generated that rotates the housing 1 (communication device 100) around the horizontal pipe P1 as its central axis, the housing 1 (communication device 100) is less likely to tilt relative to the vertical direction. Note that the torque that rotates the housing 1 (communication device 100) around the horizontal pipe P1 as its central axis may be generated by strong winds such as those caused by a typhoon.

[0038] Furthermore, according to this embodiment, the height of the first protrusion 4 can be reduced compared to a configuration in which the horizontal pipe P1 is arranged on the upper surface of the first protrusion 4. More specifically, in a configuration in which the horizontal pipe P1 is arranged on the upper surface of the first protrusion 4, a structure for supporting the horizontal pipe P1 is required above the third insertion hole 7a, the fourth insertion hole 7b, and the seventh insertion hole 8a. In contrast, according to this embodiment, the horizontal pipe P1 is arranged on the upper surface of the housing 1 (the upper surface 22a of the upper wall portion 22), so there is no need to provide a structure for supporting the horizontal pipe P1 above the third insertion hole 7a, the fourth insertion hole 7b, and the seventh insertion hole 8a. Therefore, the height of the first protrusion 4 can be reduced compared to a configuration in which the horizontal pipe P1 is arranged on the upper surface of the first protrusion 4. As a result, the housing 1 (communication device 100) can be made smaller.

[0039] Next, the communication device 100 of this embodiment will be described with reference to Fig. 8 and Fig. 9. Fig. 8 is a front view showing the communication device 100 attached to the vertical pipe P2. Fig. 9 is a side view showing the communication device 100 attached to the vertical pipe P2. As shown in Figs. 8 and 9, the housing 1 can be placed on the vertical pipe P2. The vertical pipe P2 is a pipe extending along the vertical direction. In this embodiment, the vertical pipe P2 extends along the vertical direction.

[0040] The vertical pipe P2 is a pipe for supplying resources or energy, similar to the horizontal pipe P1 described with reference to Fig. 6. The vertical pipe P2 is, for example, a gas pipe, an electric pipe, or a water pipe.

[0041] When the housing 1 is disposed on the vertical pipe P2, the third bundling member BA3 is inserted into the third insertion hole 7a (FIG. 1) and the fourth insertion hole 7b (FIG. 1), and the third bundling member BA3 bundles the vertical pipe P2 to the first protrusion 4. Similarly, the fourth bundling member BA4 is inserted into the fifth insertion hole 7c (FIG. 1) and the sixth insertion hole 7d (FIG. 1), and the fourth bundling member BA4 bundles the vertical pipe P2 to the second protrusion 5. The third bundling member BA3 and the fourth bundling member BA4 are, for example, cable ties such as insulation locks.

[0042] When the housing 1 is disposed on the vertical pipe P2, the rear surface 4b of the first protrusion 4, the rear surface 23b of the rear wall 23, and the rear surface 5b of the second protrusion 5, which were described with reference to Fig. 4, abut against the front surface of the vertical pipe P2. In other words, the rear surface 4b of the first protrusion 4, the rear surface 23b of the rear wall 23, and the rear surface 5b of the second protrusion 5 include abutment portions that abut against the front surface of the vertical pipe P2.

[0043] According to this embodiment, the upper surface 22a of the upper wall portion 22 (the upper surface of the housing 1) is open above so that the horizontal pipe P1 can be placed in front of the front surface 4a of the first protrusion 4. This makes it easier to bind the third binding member BA3.

[0044] 1 are used when mounting the housing 1 (communication device 100) on a wall. Specifically, fastening members such as screws are inserted into the seventh insertion hole 8a and the eighth insertion hole 8b, respectively, to mount the housing 1 (communication device 100) on the wall.

[0045] Next, the communication device 100 of this embodiment will be described with reference to FIG. 10. FIG. 10 is a bottom view showing the communication device 100 of this embodiment. As shown in FIG. 10, the communication device 100 further includes a bushing member 9 (bush). The bushing member 9 is arranged in the housing 1. In this embodiment, the bushing member 9 is arranged on the lower surface of the housing 1. Specifically, the bushing member 9 is arranged in the lower wall portion 32 of the cover member 3. More specifically, the lower wall portion 32 of the cover member 3 has a fitting hole 3A. The fitting hole 3A penetrates the lower wall portion 32 of the cover member 3. In this embodiment, the fitting hole 3A is a notch extending forward from the rear end of the lower wall portion 32 (see FIG. 21). The bushing member 9 is arranged in the housing 1 so that a portion of the bushing member 9 fits into the fitting hole 3A.

[0046] As shown in Fig. 10, the bushing member 9 has two insertion portions 9A and 9B. A cable member CA, which will be described with reference to Fig. 13, is inserted into each of the two insertion portions 9A and 9B. The insertion portions 9A and 9B will be described later with reference to Fig. 13.

[0047] Next, the communication device 100 of this embodiment will be described with reference to FIG. 11. FIG. 11 is a front view showing the communication device 100 with the cover member 3 removed. As shown in FIG. 11, the communication device 100 further includes a terminal block 10 and a support member 11. The housing 1 houses the terminal block 10 and the support member 11. That is, the terminal block 10 and the support member 11 are disposed inside the housing 1. The support member 11 supports the bush member 9. The terminal block 10 is mounted on a circuit board 15, which will be described with reference to FIG. 12, and the support member 11 has a through-hole through which the terminal block 10 passes. The terminal block 10 is an example of a mounted component.

[0048] 11, the housing 1 further houses a battery 12. FIG. 11 illustrates a first size battery 12A as the battery 12. A support member 11 supports the battery 12. The battery 12 is detachable from the housing 1.

[0049] Next, the support member 11 will be described with reference to FIG. 11. As shown in FIG. 11, the communication device 100 of this embodiment includes a bushing attachment portion 13. A bushing member 9 is attached to the bushing attachment portion 13. The bushing attachment portion 13 is provided inside the housing 1. Specifically, the bushing attachment portion 13 is a part of the support member 11. More specifically, the support member 11 has a base portion 111. The base portion 111 is, for example, plate-shaped. In this embodiment, the base portion 111 extends in the up-down and left-right directions. The bushing attachment portion 13 is connected to the lower end of the base portion 111 and protrudes downward from the lower end of the base portion 111. A through-hole through which the terminal block 10 passes is formed in the base portion 111.

[0050] As shown in FIG. 11 , the support member 11 further has a first claw portion 146 and a second claw portion 147. The first claw portion 146 and the second claw portion 147 are connected to the front surface of the base portion 111 and protrude forward from the base portion 111. The first claw portion 146 is located below the battery 12 and supports the battery 12. According to this embodiment, the battery 12 can be supported by the first claw portion 146. Therefore, a separate member such as a battery cover is not required. This reduces the number of parts of the communication device 100. The second claw portion 147 will be described later with reference to FIG. 12 .

[0051] Next, the communication device 100 of this embodiment will be described with reference to Fig. 12. Fig. 12 is a perspective view showing the internal configuration of the communication device 100 of this embodiment. As shown in Fig. 12, the support member 11 has a first side wall portion 141, an upper wall portion 142, a second side wall portion 143, and an inner wall portion 144. The base portion 111, the first side wall portion 141, the upper wall portion 142, the second side wall portion 143, and the inner wall portion 144 form the battery housing portion 14 that houses the battery 12 described with reference to Fig. 11.

[0052] The first side wall 141 forms the right wall of the battery housing section 14. The first side wall 141 protrudes forward from the base section 111. In this embodiment, the first side wall 141 is connected to the right end of the base section 111 and protrudes forward from the right end of the base section 111. The first side wall 141 extends downward from the right end of the upper wall section 142. More specifically, the first side wall 141 extends at least to a position facing the first claw section 146 in the left-right direction.

[0053] The upper wall portion 142 constitutes the upper wall of the battery accommodating portion 14. The upper wall portion 142 protrudes forward from the base portion 111. In this embodiment, the upper wall portion 142 is connected to the upper end of the base portion 111 and protrudes forward from the upper end of the base portion 111. The upper wall portion 142 extends in the left-right direction. In this embodiment, the upper wall portion 142 extends along the upper end of the base portion 111 from the right end to the left end of the base portion 111.

[0054] The second side wall 143 faces the first side wall 141 and constitutes the left wall of the battery accommodating section 14. The second side wall 143 protrudes forward from the base 111. In this embodiment, the second side wall 143 is connected to the left end of the base 111 and protrudes forward from the left end of the base 111. The second side wall 143 extends downward from the left end of the upper wall 142. More specifically, the second side wall 143 extends at least to a position facing the first claw 146 in the left-right direction. In this embodiment, the second side wall 143 extends to the lower end of the base 111.

[0055] The inner wall portion 144 faces the upper wall portion 142 and constitutes the lower wall of the battery accommodating portion 14. The inner wall portion 144 protrudes forward from the base portion 111. The inner wall portion 144 is connected to the second side wall portion 143 and extends rightward from the second side wall portion 143. The inner wall portion 144 is arranged alongside the first claw portion 146 in the left-right direction. The right end of the inner wall portion 144 faces the first claw portion 146 and forms a gap between it and the first claw portion 146. The first claw portion 146 is arranged between the inner wall portion 144 and the first side wall portion 141. The first claw portion 146 forms a gap between it and the first side wall portion 141.

[0056] The portion of the base portion 111 that is surrounded by the first side wall portion 141, the upper wall portion 142, the second side wall portion 143, the inner wall portion 144, and the first claw portion 146 forms the bottom wall of the battery accommodating portion 14. Specifically, the portion of the front surface of the base portion 111 that is surrounded by the first side wall portion 141, the upper wall portion 142, the second side wall portion 143, the inner wall portion 144, and the first claw portion 146 forms an arrangement surface 111a on which the battery 12 described with reference to FIG. 11 is arranged.

[0057] The second claw portion 147 faces the first side wall portion 141. More specifically, the second claw portion 147 is disposed between the first side wall portion 141 and the second side wall portion 143. The second claw portion 147 clamps the battery 12A shown in FIG. 11 together with the first side wall portion 141. Therefore, the second claw portion 147 can prevent the battery 12A from wobbling in the left-right direction.

[0058] Next, the support member 11 will be further described with reference to Fig. 12. As shown in Fig. 12, the communication device 100 further includes a circuit board 15. The circuit board 15 is housed inside the housing 1. The base portion 111 supports the circuit board 15 on the rear side. Wiring is formed on the circuit board 15. The circuit board 15 is, for example, a printed circuit board.

[0059] The terminal block 10 is mounted on the circuit board 15. The communication device 100 further includes a wireless communication unit, a processing unit, a storage unit, and a power supply unit. The wireless communication unit, the processing unit, the storage unit, and the power supply unit are mounted on the circuit board 15 and housed inside the housing 1. The wireless communication unit, the processing unit, the storage unit, and the power supply unit are examples of mounted components. For example, the terminal block 10, the wireless communication unit, the processing unit, the storage unit, and the power supply unit are mounted on the front surface of the circuit board 15. The circuit board 15 may be a double-sided board. In this case, the terminal block 10 is mounted on the front surface of the circuit board 15. At least one of the wireless communication unit, the processing unit, the storage unit, and the power supply unit is mounted on the rear surface of the circuit board 15, and the rest are mounted on the front surface of the circuit board 15. Alternatively, all of the wireless communication unit, the processing unit, the storage unit, and the power supply unit may be mounted on the rear surface of the circuit board 15.

[0060] 11 supplies power to drive the wireless communication unit, processing unit, storage unit, and power supply unit. More specifically, power is supplied from the battery 12 to the power supply unit. The power supply unit generates drive power to operate the wireless communication unit, processing unit, storage unit, and power supply unit based on the power supplied from the battery 12. The power supply unit includes, for example, a DC-DC converter.

[0061] The wireless communication unit is connected to a wireless communication network and performs wireless communication via the wireless communication network. The wireless communication unit includes, for example, a wireless communication module that complies with the communication protocol of the wireless communication network. The wireless communication network is, for example, a wide-area wireless network such as a PHS (Personal Handy-phone System) network, a FOMA (Freedom Of Mobile Multimedia Access) network, an LTE (Long Term Evolution) network, a 4G (Fourth Generation Mobile Communication System) network, or a 5G (Fifth Generation Mobile Communication System) network.

[0062] The processing unit controls the operation of each unit of the communication device 100. The processing unit includes a processor such as a CPU (Central Processing Unit) or an MPU (Micro Controller Unit).

[0063] The storage unit includes a main storage device such as a semiconductor memory and an auxiliary storage device such as a semiconductor memory. For example, the semiconductor memory includes a random access memory (RAM) and a read-only memory (ROM). Alternatively, the semiconductor memory may include at least one of a flash memory, an erasable programmable read-only memory (EPROM), and an electrically erasable programmable read-only memory (EEPROM) instead of or in addition to the RAM and ROM.

[0064] The storage unit stores the measurement results acquired from the measurement device described with reference to Fig. 1. The storage unit also stores a computer program. The processing unit controls each unit of the communication device 100 by executing the computer program stored in the storage unit.

[0065] Next, the bushing member 9 and the bushing mounting portion 13 will be described with reference to Figures 12 and 13. As shown in Figure 12, the bushing mounting portion 13 is located below the terminal block 10. The bushing member 9 is fitted into the bushing mounting portion 13 from the front of the bushing mounting portion 13.

[0066] Fig. 13 is an enlarged front view of a portion of the communication device 100 with the cover member 3 removed. As shown in Fig. 13, a cable member CA passes through the bush member 9. When the cable member CA passes through the bush member 9, one end of the cable member CA is introduced into the housing 1. The cable member CA is, for example, an electric wire.

[0067] Specifically, the bushing member 9 is made of rubber or synthetic resin. The insertion portions 9A and 9B are in the form of a film, and the cable member CA can be inserted into the insertion portions 9A and 9B by making a cross-shaped cut in the underside of the insertion portions 9A and 9B using, for example, a flat-head screwdriver or a cutter knife.

[0068] According to this embodiment, the cable member CA is gripped by the elasticity of the bush member 9. As a result, no gap is created between the bush member 9 and the cable member CA, which prevents insects from entering the housing 1 through the gap between the bush member 9 and the cable member CA.

[0069] One end of the cable member CA introduced into the housing 1 is connected to the terminal block 10. Specifically, the terminal block 10 has a connection portion 10a, and one end of the cable member CA is connected to the connection portion 10a of the terminal block 10. More specifically, the cable member CA has a conductor CW and a covering member that covers the conductor CW. At one end of the cable member CA, the covering member is stripped, exposing the conductor CW. The exposed conductor CW is connected to the connection portion 10a of the terminal block 10.

[0070] The other end of the cable member CA is connected to the measuring device described with reference to Fig. 1. The cable member CA transmits a signal indicating the measurement result of the measuring device to the terminal block 10. The signal indicating the measurement result is transmitted from the terminal block 10 to a processing unit mounted on the circuit board 15 via the circuit board 15 described with reference to Fig. 12.

[0071] Although FIG. 13 illustrates a state in which two cable members CA are connected to the terminal block 10, one cable member CA may be connected to the terminal block 10.

[0072] The bushing member 9 has a shape that allows it to be attached to the bushing attachment portion 13 only when it is in a specific orientation relative to the bushing attachment portion 13. Therefore, the bushing member 9 cannot be attached to the bushing attachment portion 13 in an orientation other than the specific orientation, which prevents an operator from accidentally attaching the bushing member 9 to the bushing attachment portion 13 in an orientation other than the specific orientation, thereby preventing a gap from being created between the bushing member 9 and the housing 1. As a result, it is possible to prevent insects from entering the interior of the housing 1 through a gap that occurs between the bushing member 9 and the housing 1. Therefore, according to this embodiment, it becomes more difficult for insects to enter the interior of the housing 1. Hereinafter, the specific orientation may be referred to as the "normal orientation."

[0073] Next, the bushing attachment portion 13 will be described with reference to Fig. 14. Fig. 14 is a top view showing the bushing attachment portion 13. As shown in Fig. 14, the bushing attachment portion 13 has a first fitting portion 131, a second fitting portion 132, a third fitting portion 133, a first connecting portion 134, and a second connecting portion 135. Note that Fig. 14 shows a partial cross section of the first connecting portion 134 and a partial cross section of the second connecting portion 135.

[0074] The first fitting portion 131 and the second fitting portion 132 are plate-shaped and extend in the front-rear direction. The first fitting portion 131 and the second fitting portion 132 face each other in the left-right direction. The third fitting portion 133 is plate-shaped and extends in the left-right direction. The left end of the third fitting portion 133 connects to the first fitting portion 131. The right end of the third fitting portion 133 connects to the second fitting portion 132. In this embodiment, the left end of the third fitting portion 133 connects to the rear end of the first fitting portion 131. Similarly, the right end of the third fitting portion 133 connects to the rear end of the second fitting portion 132.

[0075] The bushing attachment portion 13 has a first corner 136a at the connection point between the first fitting portion 131 and the third fitting portion 133. Specifically, the first corner 136a is the inner circumferential surface of the connection point between the first fitting portion 131 and the third fitting portion 133. The first corner 136a has a specific shape. In this embodiment, the first corner 136a has an arc shape in a plan view. More specifically, the first corner 136a has an arc shape with a specific radius of curvature.

[0076] The bushing attachment portion 13 has a second corner 136b at the connection point between the second fitting portion 132 and the third fitting portion 133. Specifically, the first corner 136a is the inner circumferential surface of the connection point between the second fitting portion 132 and the third fitting portion 133. The second corner 136b has a specific shape. In this embodiment, the second corner 136b has an arc shape in a plan view. More specifically, the second corner 136b has an arc shape with a specific radius of curvature.

[0077] The first corner 136a and the second corner 136b may have different shapes. For example, the first corner 136a and the second corner 136b may have different radii of curvature.

[0078] The first connecting portion 134 is connected to the first fitting portion 131 and extends upward from the first fitting portion 131. The second connecting portion 135 is connected to the second fitting portion 132 and extends upward from the second fitting portion 132. The tips (upper ends) of the first connecting portion 134 and the second fitting portion 132 are connected to the base portion 111 described with reference to FIGS. 11 and 12.

[0079] 14, the first fitting portion 131 has a width W1. The width W1 is the width in the left-right direction. Specifically, the width W1 of the first fitting portion 131 indicates the distance or length from the first connecting portion 134 to the right end of the first fitting portion 131.

[0080] Next, the bushing member 9 will be described with reference to Figures 15 to 18. Figure 15 is a front view showing the bushing member 9. Figure 16 is a perspective view showing the bushing member 9. Figure 17 is another perspective view showing the bushing member 9.

[0081] As shown in FIG. 15, the bushing member 9 includes an upper portion 9U (first layer) and a lower portion 9L (second layer). The lower portion 9L is connected to the underside of the upper portion 9U. Specifically, the bushing member 9 includes a bushing main body 91, a first protruding portion 92, a second protruding portion 93, a third protruding portion 94, and a fourth protruding portion 95. The bushing main body 91 also includes a protruding portion 91a. The protruding portion 91a indicates a portion of the bushing main body 91 that protrudes downward beyond the second protruding portion 93 and the fourth protruding portion 95. The upper portion 9U of the bushing member 9 includes a portion of the bushing main body 91 above the protruding portion 91a, and the first protruding portion 92 to the fourth protruding portion 95. The lower portion 9L of the bushing member 9 includes the protruding portion 9a, an inserted portion 9A, and an inserted portion 9B. The inserted portion 9A and the inserted portion 9B protrude downward from the lower surface of the protruding portion 9a.

[0082] The cable member CA described with reference to Fig. 13 passes through the bushing main body 91. As shown in Fig. 15, the first overhanging portion 92 and the second overhanging portion 93 overhang leftward from the bushing main body 91. The second overhanging portion 93 is located below the first overhanging portion 92, and the first overhanging portion 92 and the second overhanging portion 93 face each other in the up-down direction. As shown in Figs. 16 and 17, the first overhanging portion 92 and the second overhanging portion 93 extend in the front-rear direction. The first fitting portion 131 of the bushing attachment portion 13 described with reference to Fig. 14 fits between the first overhanging portion 92 and the second overhanging portion 93.

[0083] The first protruding portion 92 has a width W2. The second protruding portion 93 has a width W3. The width W2 indicates the amount by which the first protruding portion 92 protrudes from the bushing main body 91. In other words, the width W2 indicates the length or distance from the bushing main body 91 to the left end of the first protruding portion 92. Similarly, the width W3 indicates the amount by which the second protruding portion 93 protrudes from the bushing main body 91. In other words, the width W3 indicates the length or distance from the bushing main body 91 to the left end of the second protruding portion 93.

[0084] The width W2 of the first overhanging portion 92 is narrower than the width W3 of the second overhanging portion 93. Furthermore, the width W1 of the first fitting portion 131 described with reference to FIG. 14 is narrower than the width W3 of the second overhanging portion 93. Therefore, the bushing member 9 cannot be attached to the bushing attachment portion 13 by turning the bushing member 9 upside down. This makes it possible to prevent a gap from being generated between the bushing member 9 and the housing 1.

[0085] More specifically, in this embodiment, the normal position is a position in which the first protruding portion 92 is positioned above the second protruding portion 93. Therefore, if the bushing member 9 is positioned such that the second protruding portion 93 is positioned above the first protruding portion 92, the bushing member 9 cannot be attached to the bushing attachment portion 13.

[0086] As shown in Figure 15, the third overhang portion 94 overhangs to the right from the bushing main body 91. The fourth overhang portion 95 is located below the third overhang portion 94 and overhangs to the right from the bushing main body 91. The third overhang portion 94 and the fourth overhang portion 95 face each other in the up-down direction. As shown in Figures 16 and 17, the third overhang portion 94 and the fourth overhang portion 95 extend in the front-rear direction. The second fitting portion 132 of the bushing mounting portion 13 described with reference to Figure 14 fits between the third overhang portion 94 and the fourth overhang portion 95.

[0087] A part of the bushing main body 91 fits into the fitting hole 3A of the cover member 3 described with reference to Fig. 10. Specifically, the protruding portion 91a of the bushing main body 91 fits into the fitting hole 3A of the cover member 3.

[0088] As shown in FIGS. 16 and 17 , the bushing member 9 further includes a fifth overhanging portion 96 and a sixth overhanging portion 97. The fifth overhanging portion 96 and the sixth overhanging portion 97 are included in an upper portion 9U of the bushing member 9. The fifth overhanging portion 96 and the sixth overhanging portion 97 overhang rearward from the bushing main body 91. The fifth overhanging portion 96 and the sixth overhanging portion 97 extend in the left-right direction. The left end of the fifth overhanging portion 96 connects to the rear end of the first overhanging portion 92, and the right end of the fifth overhanging portion 96 connects to the rear end of the third overhanging portion 94. The left end of the sixth overhanging portion 97 connects to the rear end of the second overhanging portion 93, and the right end of the sixth overhanging portion 97 connects to the rear end of the fourth overhanging portion 95. The third fitting portion 133 of the bushing mounting portion 13 described with reference to FIG. 14 fits between the fifth overhanging portion 96 and the sixth overhanging portion 97.

[0089] 15 to 17, the bushing member 9 has a first notch 98 and a second notch 99. The first notch 98 and the second notch 99 are formed on the surface of the bushing member 9. In this embodiment, the first notch 98 and the second notch 99 are formed on an upper portion 9U of the bushing member 9, and the top surfaces of the first notch 98 and the second notch 99 are open. More specifically, the first notch 98 and the second notch 99 are formed on an upper portion of the bushing main body 91, and extend rearward from the front end of the bushing main body 91.

[0090] Next, the bushing member 9 will be described with reference to Fig. 18. Fig. 18 is a cross-sectional view of the bushing member 9. As shown in Fig. 18, the bushing member 9 further has a first hole portion 9C and a second hole portion 9D. In addition, the bushing main body portion 91 further has a first corner portion R1 to a fourth corner portion R4.

[0091] The upper surface of the first hole portion 9C is open. The first hole portion 9C extends downward from the upper surface of the bushing member 9. More specifically, the first hole portion 9C extends downward from the upper surface of the bushing main body 91. The lower surface of the first hole portion 9C is covered by the inserted portion 9A. Therefore, the cable member CA inserted into the inserted portion 9A passes through the first hole portion 9C. Similarly, the upper surface of the second hole portion 9D is open. The second hole portion 9D extends downward from the upper surface of the bushing member 9. More specifically, the second hole portion 9D extends downward from the upper surface of the bushing main body 91. The lower surface of the second hole portion 9D is covered by the inserted portion 9B. Therefore, the cable member CA inserted into the inserted portion 9B passes through the second hole portion 9D.

[0092] The first notch 98 described with reference to Figures 15 to 17 communicates with the first hole 9C. Similarly, the second notch 99 described with reference to Figures 15 to 17 communicates with the second hole 9D.

[0093] The first corner R1 of the bushing main body 91 has a shape that conforms to the first corner 136a of the bushing mounting portion 13 described with reference to FIG. 14. The second corner R2 of the bushing main body 91 has a shape that conforms to the second corner 136b of the bushing mounting portion 13 described with reference to FIG. 14. On the other hand, the third corner R3 of the bushing main body 91 has a different shape from the first corner R1 and the second corner R2 of the bushing main body 91. That is, the third corner R3 of the bushing main body 91 has a different shape from the first corner 136a and the second corner 136b of the bushing mounting portion 13 described with reference to FIG. 14. Similarly, the fourth corner R4 of the bushing main body 91 has a different shape from the first corner R1 and the second corner R2 of the bushing main body 91. That is, the fourth corner R4 of the bushing main body 91 has a different shape from the first corner 136a and the second corner 136b of the bushing mounting portion 13 described with reference to FIG. 14. Specifically, the first corner R1 and the second corner R2 of the bushing body 91 have an arc shape in plan view, while the third corner R3 and the fourth corner R4 of the bushing body 91 have a right-angle shape in plan view.

[0094] According to this embodiment, when attaching the bushing member 9 to the bushing attachment portion 13, the first corner R1 and the second corner R2 of the bushing main body 91 can be brought into contact with the first corner 136a and the second corner 136b of the bushing attachment portion 13. On the other hand, the third corner R3 and the fourth corner R4 of the bushing main body 91 cannot be brought into contact with the first corner 136a and the second corner 136b of the bushing attachment portion 13, and therefore the bushing member 9 cannot be attached to the bushing attachment portion 13 by reversing the front and rear of the bushing member 9. This makes it possible to prevent a gap from being generated between the bushing member 9 and the housing 1.

[0095] Next, the communication device 100 of this embodiment will be described with reference to FIG. 19. FIG. 19 is an enlarged cross-sectional view of a portion of the communication device 100 of this embodiment. As shown in FIG. 19, when the bushing member 9 is attached to the bushing attachment portion 13 in the correct position, the first notch 98 is located on the surface of the bushing member 9 that is closer to the connection portion 10a of the terminal block 10, and extends from the first hole 9C in a direction approaching the connection portion 10a of the terminal block 10. Similarly, when the bushing member 9 is attached to the bushing attachment portion 13 in the correct position, the second notch 99 described with reference to FIGS. 15 to 17 is located on the surface of the bushing member 9 that is closer to the connection portion 10a of the terminal block 10, and extends from the second hole 9D (see FIG. 18) in a direction approaching the connection portion 10a of the terminal block 10. This facilitates the operation of connecting the cable member CA described with reference to FIG. 13 to the connection portion 10a of the terminal block 10.

[0096] Next, the communication device 100 of this embodiment will be described with reference to Figures 20 to 22. Figure 20 is yet another perspective view showing the bushing member 9. As shown in Figure 20, the upper part 9U of the bushing member 9 has a lower surface 9Ua. The lower surface 9Ua is disposed around the protrusion 91a.

[0097] Specifically, the lower surface 9Ua has a first lower surface portion 91b and a second lower surface portion 91c. The first lower surface portion 91b is located to the left of the protruding portion 91a. The second lower surface portion 91c is located to the right of the protruding portion 91a. The first lower surface portion 91b and the second lower surface portion 91c extend in the front-to-rear direction. The first lower surface portion 91b includes the lower surface of the second overhanging portion 93. The second lower surface portion 91c includes the lower surface of the fourth overhanging portion 95.

[0098] As shown in FIG. 20, the front side of the upper portion 9U of the bushing member 9 protrudes forward from the protruding portion 91a, and the lower surface 9Ua further has a third lower surface portion 91d located in front of the protruding portion 91a.

[0099] Fig. 21 is a rear view showing the cover member 3 and the bush member 9. Fig. 22 is a perspective view showing the cover member 3. In detail, Figs. 21 and 22 show the inside of the cover member 3.

[0100] 21 , the bushing member 9 contacts the inner surface of the housing 1. In the present embodiment, the bushing member 9 contacts the inner surface of the lower wall portion 32 of the cover member 3. Specifically, the lower surface 9Ua described with reference to FIG. 20 contacts the inner surface of the lower wall portion 32 of the cover member 3. Therefore, the lower surfaces of the second protruding portion 93 and the fourth protruding portion 95 contact the inner surface of the lower wall portion 32 of the cover member 3. In addition, the lower surface (third lower surface portion 91d) of the portion of the upper portion 9U of the bushing member 9 that protrudes forward relative to the protrusion 91a contacts the inner surface of the lower wall portion 32 of the cover member 3.

[0101] 22, the housing 1 has a contact portion 35. In this embodiment, the cover member 3 has the contact portion 35. The contact portion 35 is provided on the inner surface of the lower wall portion 32 of the cover member 3. Specifically, the contact portion 35 is provided around the fitting hole 3A.

[0102] The bushing member 9 attached to the bushing attachment portion 13 comes into contact with the contact portion 35. Specifically, the lower surface 9Ua described with reference to FIG. 20 comes into contact with the contact portion 35. Therefore, the lower surfaces of the second protruding portion 93 and the fourth protruding portion 95 come into contact with the contact portion 35. In addition, the lower surface (third lower surface portion 91d) of the portion of the upper portion 9U of the bushing member 9 that protrudes forward relative to the protrusion 91a comes into contact with the contact portion 35.

[0103] According to the present embodiment, the width W3 of the second overhanging portion 93 is larger than the width W2 of the first overhanging portion 92. Similarly, the width of the fourth overhanging portion 95 is larger than the width W2 of the third overhanging portion 94. Therefore, the area of ​​contact between the bushing member 9 and the inner surface of the housing 1 can be increased. As a result, foreign matter such as dust is less likely to enter the interior of the housing 1 from the outside of the housing 1, improving the dustproof performance of the communication device 100.

[0104] Next, the communication device 100 of this embodiment will be described with reference to Figures 22 to 24. Figure 23 is a partially enlarged cross-sectional view showing the cover member 3 and the bush member 9.

[0105] 22 and 23, the housing 1 has a groove 36. The groove 36 allows rainwater that has entered the housing 1 to be discharged to the outside of the housing 1. In this embodiment, the groove 36 is provided in the lower wall 32 of the cover member 3.

[0106] 23 , the groove 36 has a first groove 36a and a second groove 36b. The first groove 36a is provided on the inner circumferential surface 3A1 of the fitting hole 3A and extends in the same direction as the fitting hole 3A. The second groove 36b is provided on the inner surface of the housing 1 and communicates with the first groove 36a. In this embodiment, the second groove 36b is provided on the inner surface of the lower wall portion 32 of the cover member 3. More specifically, the second groove 36b is provided in the contact portion 35. Rainwater that has entered the housing 1 flows from the second groove 36b into the first groove 36a, and then flows through the first groove 36a to be discharged to the outside of the housing 1.

[0107] FIG. 24 is a cross-sectional view showing the housing 1 and the bushing member 9. As shown in FIG. 24, when the communication device 100 (housing 1) rotates rearward about the horizontal pipe P1 and assumes an attitude inclined with respect to the vertical direction, rainwater RW that has entered the housing 1 may remain inside the housing 1. According to this embodiment, the rainwater RW that has entered the housing 1 is discharged to the outside of the housing 1 through the groove portion 36 described with reference to FIGS. 22 and 23. Therefore, it is possible to prevent rainwater from remaining inside the housing 1. Note that the communication device 100 (housing 1) may rotate about the horizontal pipe P1 due to strong winds such as those caused by a typhoon.

[0108] Next, the communication device 100 of this embodiment will be described with reference to Fig. 12 and Fig. 25. Fig. 25 is a front view showing the communication device 100 with the cover member 3 removed. As shown in Fig. 25, the communication device 100 of this embodiment can accommodate a second-size battery 12B in the housing 1. The battery 12B is larger in size than the battery 12A shown in Fig. 11.

[0109] Specifically, the second claw portion 147 described with reference to FIG. 12 can be separated from the base portion 111. For example, if the support member 11 is made of resin, the second claw portion 147 can be separated from the base portion 111 by bending it. When the battery 12B is attached to the housing 1, the second claw portion 147 is separated from the base portion 111 to expand the space of the battery accommodating portion 14. When the battery 12B is accommodated in the battery accommodating portion 14, the second side wall portion 143, together with the first side wall portion 141, sandwiches the battery 12B. Therefore, rattling of the battery 12B in the left-right direction can be suppressed.

[0110] Next, the communication device 100 of this embodiment will be described with reference to Fig. 26 and Fig. 27. Fig. 26 is a cross-sectional view showing the communication device 100 when the battery 12 is inserted into the case member 2. As shown in Fig. 26, the support member 11 supports the circuit board 15 on the rear side. Specifically, the support member 11 holds the circuit board 15 at a position rearward and away from the base portion 111. Therefore, the battery 12 (metal part) can be held at a position away from the wireless communication unit mounted on the circuit board 15. This allows stable wireless communication.

[0111] 26, when the battery 12 is housed inside the housing 1, the cover member 3 is removed from the case member 2. The battery 12 is inserted into the case member 2 through the opening 2A of the case member 2. Specifically, the battery 12 can be inserted into the case member 2 at an angle.
