DETAILED DESCRIPTION

Accordingly, the present disclosure intends to provide a wireless communication device that is configured to arrange a plurality of internal substrates, arranged inside a housing, along a predetermined direction, thereby miniaturizing the wireless communication device and, as a result, achieving aesthetic harmonization with building exterior and city view.

Some exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings. In the following description, like reference numerals preferably designate like elements, although the elements are shown in different drawings. Further, in the following description of some embodiments, a detailed description of known functions and configurations incorporated herein will be omitted for the purpose of clarity and for brevity.

Additionally, alphanumeric codes such as first, second, i), ii), a), b), etc., in numbering components are used solely for the purpose of differentiating one component from the other but not to imply or suggest the substances, the order, or sequence of the components. Throughout this specification, when parts “include” or “comprise” a component, they are meant to further include other components, not excluding thereof unless there is a particular description contrary thereto.

Herein, the horizontal length refers to a length in a direction parallel to the Y-axis with reference to FIG. 1, and the vertical length refers the length in a direction parallel to the Z-axis with reference to FIG. 1. The thickness refers to the length in a direction parallel to the X axis with reference to FIG. 1.

FIG. 1 illustrates a wireless communication device 10 according to an embodiment of the present disclosure.

Specifically, FIG. 1 at (a) shows a perspective view of the wireless communication device 10, and FIG. 1 at (b) shows a rear perspective view thereof.

Referring to FIG. 1 at (a) and FIG. 1 at (b), the wireless communication device 10 may include a housing 110.

The housing 110 may include a lower case 112 and an upper radome 114.

The lower case 112 and the upper radome 114 may be coupled to each other and, in the coupled state, may define a storage space between the lower housing 112 and upper radome 114.

The housing 110 may contain the antenna 120 and the plurality of internal substrates 12 in the storage space. As a result, the housing 110 may protect the antenna 120 and the plurality of internal substrates 12 from external shocks.

The housing 110 may have a shape in which one of the horizontal length and the vertical length is relatively longer than the other.

For example, the value obtained by dividing the longer of the horizontal length and the vertical length of the housing 110 by the smaller length may be 3.0 or larger.

The wireless communication device 10 according to an embodiment of the present disclosure can secure a storage space having a relatively large cross-sectional area by configuring one of the horizontal length and the vertical length of the housing 110 to be relatively long with respect to the other.

As a result, the plurality of internal substrates 12 may be arranged along a predetermined direction in the storage space of the housing 110. Meanwhile thickness of the housing 110 may be relatively thin.

For example, with the lower case 112 and the upper radome 114 coupled, the thickness of the housing 110 may be 165 mm or shorter.

Thus, the wireless communication device 10 according to an embodiment of the present disclosure may be a slim case shape as a whole, thereby having an aesthetic advantage.

The horizontal length, vertical length, and thickness of housing 110 may be 285 mm, 950 mm, and 150 mm, respectively. However, the present disclosure is not limited thereto.

Meanwhile, the wireless communication device 10 may additionally include a plurality of external connection ports 115 and a GPS antenna (not shown).

A plurality of external connection ports 115 may be formed on one side of the housing 110. The wireless communication device 10 may be connected to an external device (not shown) or other wireless communication device 10 via a plurality of external connection ports 115.

The plurality of external connection ports 115 may include, but are not limited to, an alarm port, an optical port, a power supply port, and an RTS port.

The wireless communication device 10 may transmit and receive GPS signals via a GPS antenna (not shown). The GPS antenna may be exposed outside the housing 110 for smooth transmission and reception of GPS signals.

FIG. 2 is an exploded perspective view of a wireless communication device 10 according to an embodiment of the present disclosure.

Specifically, FIG. 2 at (a) illustrates an exploded perspective view of a state in which a plurality of internal substrates 12 are disposed on the lower case 112, and FIG. 2 at (b) illustrates an exploded view in which the plurality of outer substrates 12 is separated from the lower case 112.

Referring to FIG. 2 at (a) and FIG. 3 at (b), the wireless communication device 10 may include an antenna 120 and a plurality of internal substrates 12.

The antenna 120 and the plurality of internal substrates 12 may be disposed within a storage space of the housing 110.

In the wireless communication device 10 according to an embodiment of the present disclosure, since the antenna 120 is disposed inside the housing 110, a separate cable is not required for connecting the antenna 120 to the wireless communication device 10. Accordingly, it is possible to minimize transmission loss that may occur by connecting the antenna 120 and the wireless communication device 10 via a cable.

The antenna 120 may be a panel antenna having a plurality of antenna elements 121, and may have a plate shape corresponding to the lower case 112.

The plurality of internal substrates 12 may be disposed between the antenna 120 and the lower case 112 in the storage space. At least one of the plurality of internal substrates 12 may be coupled with an antenna 120, through which signals may be received from or transmitted to the antenna 120.

Each internal substrate 12 of the plurality of internal substrates 12 may be disposed along a first direction parallel to a surface of the lower case 112 facing the internal substrates 12. Herein, the first direction refers to a direction in which the plurality of internal substrates 12 is arranged. For example, the first direction may be parallel to the vertical direction of the housing 110, with reference to FIG. 2.

The wireless communication device 10 according to an embodiment of the present disclosure is characterized in that the housing 110 has a thinner thickness by adopting a method in which a plurality of internal substrates 12 is arranged in a line along a predetermined direction, rather than a method of stacking a plurality thereof.

As such, the wireless communication device 10 according to an embodiment of the present disclosure may be installed in coordination with a surrounding view. As such, the wireless communication device 10 according to an embodiment of the present disclosure has aesthetic benefits.

In FIG. 2, the first direction is shown to be parallel to the vertical direction of the housing 110, but the present disclosure is not limited thereto.

For example, the first direction may be parallel to the horizontal direction of the housing 110. In this case, the plurality of internal substrates 12 may be arranged along the horizontal direction of the housing 110.

Each internal substrate 12 may be arranged in a row along the first direction, but the present disclosure is not limited thereto. For example, each of the internal substrates 12 may be disposed offset from each other along the first direction or in a zigzag shape.

Each internal substrate 12 may be electrically connected to a neighboring internal substrate 12. In this case, a region of each internal substrate 12 other than connecting region with the neighboring internal substrate 12 may not overlap with the neighboring internal substrates 12.

Accordingly, the wireless communication device 10 according to an embodiment of the present disclosure can minimize the overlapping area between each of the plurality of internal substrates 12 and maximize the area of the internal substrate 12 exposed outside. Thereby, heat generated from the plurality of internal substrates 12 may be effectively released.

The plurality of internal substrates 12 may include a front end unit 130, a power amplifying unit 140, a digital board 150, and a power supply unit 160. However, the present disclosure is not limited thereto, and the plurality of internal substrates 12 may also include other members.

The plurality of internal substrates 12 may be disposed in the order of the front end unit 130, the power amplifying unit 140, the digital board 150, and the power supply unit 160 along the first direction.

Such an arrangement of the internal substrate 12 may be an arrangement according to a processing order of signals transmitted to or received from the antenna 120. This sequence of placement can thus minimize electrical connections between each internal substrate 12 and other internal substrates 12 that are not adjacent thereto.

Accordingly, it is possible to minimize the configuration of the circuit for connecting each internal substrate 12 to another internal substrate 12, which is not adjacent thereto, and thus the configuration of the plurality of internal substrates 12 can be further simplified.

The connection area shield 810 may be disposed in at least one of each internal substrate 12 and a connection region between the internal substrate and another adjacent internal substrate 12.

For example, the connection area shield 810 may be disposed in a connection area between the second interface 142 of the power amplification unit 140 and the third interface 151 of the digital board 150, or may be located in a connection area between the fourth interface 152 of the digital board 150 and the fifth interface 161 of the power supply unit 160.

The heat pipe 920 may extend long along the first direction in which the plurality of internal substrates 12 are disposed.

The heat pipe 920 may be disposed closest to the internal substrate 12 that releases relatively large amount of heat. For example, the heat pipe 920 may be disposed closest to the power amplifier 140 where relatively large amount of heat is generated.

FIG. 10 illustrates a state in which a plurality of wireless communication devices 10 according to an embodiment of the present disclosure are connected via a hybrid cable 1010.

Specifically, FIG. 10 at (a) illustrates a state in which a plurality of wireless communication devices 10 are installed on the pole P, and FIG. 10 at (b) illustrates the connection state of the plurality of the wireless communication device 10.

Referring to FIG. 10 at (a), a plurality of wireless communication devices 10 may be installed on the pole P apart from each other. In this case, each housing 110 of the plurality of wireless communication devices 10 may be connected to one hybrid cable 1010.

Referring to FIG. 10 at (b), the hybrid cable 1010 may be electrically connected to at least one of the plurality of internal substrates 12 via the external connection port 115 formed on one side of the housing 110.

The hybrid cable 1010 may include a power cable 1011, a first cable 1012, and a second cable 1013. The power cable 1011, the first cable 1012, and the second cable 1013 may be integrally formed as one.

The power supply cable 1011 may be provided in each of the plurality of wireless communication devices 10, and may supply power to each of the plurality of wireless communication devices 10.

On the other hand, the first cable 1012 connected to one wireless communication device 10 may be configured to electrically connect with the second cable 1013 connected to another wireless communication device 10. As a result, a signal transmitted to one wireless communication device 10 may be sequentially transmitted to another wireless communication device 10.

For example, a first wireless communication device 10A and a second wireless communication device 10B may be connected by a first connection cable C1, and the second wireless communication device 10B and a third wireless communication device 10C may be coupled by a second connection cable C2.

In this case, one end of the first connection cable C1 may be electrically connected to a second cable 1013A of the first wireless communication device 10A, and the other end of the first connection cable C1 may be electrically connected with a first cable 1012B of the second wireless communication device 10B.

As a result, the signal initially delivered to the first wireless communication device 10A may be delivered to the second wireless communication device 10B via one cable C1, and the signal delivered to the second wireless communication device 10B may be delivered to the third wireless communication device 10C via another cable C2.

On the other hand, the plurality of hybrid cables 1010 may be branched from a hybrid box 1020 and connected to each housing 110 of a plurality of wireless communication devices 10.

In this case, the first connection cable C1 and the second connection cable C2 may be accommodated in the hybrid box 1020.

The hybrid box 1020 allows multiple hybrid cables 1010 to branch in one place, thereby minimizing the aesthetic impact of the hybrid cable 1010 on the surrounding view.

The housing 210 may accommodate a plurality of internal substrates 22 in a storage space. As a result, the housing 210 can protect the plurality of internal substrates 22 from external shock.

The housing 210 may have a shape in which one of the horizontal length and vertical length is relatively longer than the other.

For example, the value obtained by dividing the longer of the horizontal length and vertical length of the housing 210 by the smaller of the horizontal length and vertical length of the housing 210 may be 3.0 or larger.

The wireless communication device 20 according to another embodiment of the present disclosure can secure a storage space having a relatively large cross-sectional area by configuring one of the horizontal length and vertical length of the housing 210 to be relatively longer than the other.

As a result, the plurality of internal substrates 22 may be arranged in the storage space of the housing 210 along a predetermined direction, and the thickness of housing 210 may be relatively thin.

Thus, the wireless communication device 20 according to another embodiment of the present disclosure may have a slim case shape as a whole, thereby having an aesthetic advantage.

Furthermore, the wireless communication device 20 according to another embodiment of the present disclosure has a technical feature in that an antenna is not provided in the accommodation space of the housing 210. Thus, the thickness of the housing 210 according to another embodiment of the present disclosure may be thinner.

For example, with the lower case 212 and the upper case 214 coupled, the thickness of the housing 210 may be 80 mm or less.

The horizontal length, vertical length, and thickness of the housing 210 may be 285 mm, 950 mm, and 70 mm, respectively. However, the present disclosure is not limited thereto.

Meanwhile, the wireless communication device 20 may additionally include an antenna connection port 218, a plurality of external connection ports 215, and a GPS antenna (not shown).

The antenna connection port 218 may be formed on the housing 210 and may be connected to an antenna (not shown) disposed outside the wireless communication device 20.

A plurality of external connection ports 215 may be formed on one side of the housing 210. The wireless communication device 20 may be connected to an external device (not shown) or other wireless communication device 20 via a plurality of external connection ports 215.

The plurality of external connection ports 215 may include, but is not limited to, an alarm port, an optical port, a power supply port, and an RTS port.

The wireless communication device 20 may transmit and receive GPS signals via a GPS antenna (not shown). The GPS antenna may be exposed outside the housing 210 for smooth transmission and reception of GPS signals.

Referring to FIG. 12 at (a) and FIG. 12 at (b), the wireless communication device 20 may include the plurality of internal substrates 22.

The plurality of internal substrates 22 may be disposed between the upper case 214 and the lower case 212 in the storage space. At least one of the plurality of internal substrates 22 may be coupled with an external antenna (not shown), through which signals may be received from or transmitted to.

Each internal substrate 22 of the plurality of internal substrates 22 may be disposed along a first direction that is parallel to a surface of the lower case 212 that faces the internal substrates 22. Herein, the first direction refers to a direction in which the plurality of internal substrates 22 are arranged. For example, the first direction may be parallel to the vertical direction of the housing 210, with reference to FIG. 12.

The wireless communication device 20 according to another embodiment of the present disclosure is characterized in that the housing 210 has a thinner thickness by adopting a method in which the plurality of internal substrates 22 are arranged in a line along a predetermined direction, rather than a method of stacking the plurality of internal substrates 22.

As such, the wireless communication device 20 according to another embodiment of the present disclosure may be installed in coordination with the surrounding scenery. As such, the wireless communication device 20 according to another embodiment of the present disclosure may have aesthetic benefits.

In FIG. 12, the first direction is shown to be parallel to the vertical direction of the housing 210, but the present disclosure is not limited thereto.

For example, the first direction may be parallel to the horizontal direction of the housing 210. In this case, the plurality of internal substrates 22 may be arranged along the horizontal direction of the housing 210.

Each internal substrate 22 may be arranged in a row along the first direction, although the present disclosure is not limited thereto. For example, each of the internal substrates 22 may be disposed offset from each other along the first direction or in a zigzag shape.

Each internal substrate 22 may be electrically connected to a neighboring internal substrate 22. In this case, an area of each internal substrate 22 other than a connection area with the neighboring internal substrate 22 may not overlap with the neighboring internal substrate 22.

Accordingly, the wireless communication device 20 according to another embodiment of the present disclosure can minimize the area overlapping between each of the plurality of internal substrates 22 and maximize the area of the internal substrate 22 exposed to the outside. Thereby, heat generated from the plurality of internal substrates 22 may be effectively released.

The plurality of internal substrates 22 may include a front end unit 230, a power amplifier 240, a digital board 250, and a power supply unit 260. However, the present disclosure is not limited thereto, and the plurality of internal substrates 22 may include other members.

The plurality of internal substrates 22 may be disposed in the order of the front end unit 230, the power amplifier 240, the digital board 250, and the power supply unit 260 along the first direction.

Such an arrangement of the internal substrate 22 may be an arrangement according to a processing order of signals transmitted to or received from the antenna. This sequence of placement can thus minimize electrical connections between each internal substrate 22 and other internal substrates 22 that are not adjacent thereto.

Accordingly, it is possible to minimize the configuration of the circuit for connecting each internal substrate 22 to another internal substrate 22 which is not adjacent thereto, and thus the configuration for the plurality of internal substrate 22 may be further simplified.
