In the description of the utility model, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific situation.
[0032] In order to better understand the present invention, Figures 1 to 6 The antenna box and the signal device of the embodiment of the utility model are described in detail.
[0033] See also Figures 1 to 4 According to an embodiment of the utility model, an antenna box 100 is proposed, including a shell 10, a circuit board 20, a transmission tube 30 and a transmission line 40. The shell 10 has a accommodating cavity 12, and a docking hole 11 is provided on the surface of the shell 10, and the docking hole 11 is communicated with the accommodating cavity 12; the circuit board 20 is arranged in the accommodating cavity 12, and the circuit board 20 is configured to send and receive signals; the transmission tube 30 is inserted into the docking hole 11 and communicated with the accommodating cavity 12, and the transmission tube 30 extends toward a side away from the shell 10; there are multiple transmission lines 40 and they are spaced from each other, one end of each transmission line 40 is connected to the circuit board 20 and the other end extends into the transmission tube 30, the transmission tube 30 surrounds multiple transmission lines 40 on the outside of the shell 10, and the other end of the transmission line 40 is used to connect with a signal processing device.
[0034] Optionally, the shell 10 can be a square structure, having a accommodating cavity 12, which is mainly used to accommodate a circuit board 20. The circuit board 20 can be a printed circuit board 20 (PCBA). The circuit board 20 can be arranged in the accommodating cavity 12 of the shell 10 by bolt connection. The circuit board 20 is mainly used to receive or send signals.
[0035] Among them, the antenna box 100 has multiple transmission lines 40, each transmission line 40 can be connected to the circuit board 20 through a welding process to realize signal transmission, and adjacent transmission lines 40 are spaced apart from each other on the circuit board 20 to avoid crosstalk of electrical signals. The utility model does not specifically limit the specific number of transmission lines 40.
[0036] After the transmission line 40 is connected to the circuit board 20 in the accommodating cavity 12, it will be led out through the docking hole 11 on the shell 10, so as to be connected to the signal processing equipment outside the shell 10. The led-out transmission line 40 is often several meters long. The utility model does not impose any special limitation on the specific lead-out length of the transmission line 40, which can be determined according to actual connection requirements.
[0037] Taking into account that multiple transmission lines 40 need to be led out for several meters, in order to organize and plan them and prevent the lines from being arranged in a disorderly manner and partially exposed to the external environment, in this embodiment, a transmission tube 30 is inserted and arranged at the docking hole 11 of the shell 10, so that the multiple transmission lines 40 can be gathered and extended into the transmission tube 30, and the transmission tube 30 forms isolation protection for them, thereby forming an orderly lead-out of the lines.
[0038] Since the transmission line 40 is usually a flexible wire harness, in order to provide better protection for it, the transmission tube 30 can be optionally set to be a flexible hose, while ensuring that it has the same lead-out length as the transmission line 40 to fully cover the line and avoid failure problems caused by partial exposure.
[0039] In this embodiment, the transmission tube 30 needs to be inserted into the docking hole 11 of the shell 10. As for the specific connection method of the transmission tube 30, various methods such as fixed connection, detachable connection and integral molding can be adopted, and the utility model is not limited to this.
[0040] The present invention does not limit the specific structural shape of the transmission tube 30 , as long as it can match the shape of the docking hole 11 and form a reliable connection. In this embodiment, the transmission tube 30 is set as a round tube as an example for explanation.
[0041] The embodiment of the utility model provides an antenna box 100, by inserting a transmission tube 30 at a docking hole 11 on the surface of a shell 10 of the antenna box 100, a plurality of transmission lines 40 led out from a circuit board 20 inside the shell 10 are gathered into the transmission tube 30 for extension, thereby utilizing the transmission tube 30 to plan and organize the plurality of transmission lines 40, isolating and protecting the transmission lines 40 while ensuring their extension, preventing the transmission lines 40 from being exposed to the external environment during the connection process, reducing the risk of line failure, providing reliable guarantee for forming stable and effective signal transmission, and having a better aesthetic effect while improving the overall safety performance.
[0042] As an optional embodiment, the transmission tube 30 is detachably connected to the housing 10 .
[0043] Considering that after the transmission tube 30 is installed in the docking hole 11 of the shell 10, it may be necessary to adjust, replace, etc. the transmission tube 30, a detachable connection is formed between the transmission tube 30 and the shell 10 in this embodiment. The transmission tube 30 can be installed after the transmission wiring 40 is led out from the docking hole 11, thereby forming a covering protection for the wiring.
[0044] Optionally, the transmission pipe 30 can be a separately molded split structure, which is installed on the shell 10 after molding. There are many ways of detachable connection, such as bolt connection, threaded connection, etc. The utility model is not limited to this, and it is convenient for the staff to disassemble it.
[0045] The embodiment of the utility model provides an antenna box 100, which improves the flexibility of disassembling and assembling the transmission tube 30 by detachably connecting the transmission tube 30 and the shell 10, and can be replaced and adjusted according to different actual needs. At the same time, the transmission tube 30 can also be independently molded, simplifying the molding process of the overall structure.
[0046] As an alternative embodiment, see Figure 2 and Figure 3 An internal thread 4 is provided on the hole wall of the docking hole 11, and an external thread 5 is provided on the outer wall of the transmission tube 30. The transmission tube 30 is threadedly connected with the internal thread 4 at the docking hole 11 through the external thread 5, so that the length of the transmission tube 30 extending into the accommodating cavity 12 is adjustable.
[0047] In this embodiment, a threaded connection method is provided between the transmission tube 30 and the docking hole 11. An internal thread 4 is provided at the docking hole 11 and a corresponding external thread 5 is provided on the transmission tube 30. The threaded connection is formed by utilizing the matching relationship between the internal thread 4 and the external thread 5.
[0048] When the transmission tube 30 needs to be installed at the docking hole 11, the staff can manually screw the transmission tube 30 into the docking hole 11. At the same time, the transmission tube 30 can be screwed to adjust the lead-out length of the transmission tube 30 according to the actual lead-out length of the transmission line 40. Optionally, the transmission tube 30 can adopt a corrugated tube.
[0049] The embodiment of the utility model provides an antenna box 100, which forms a threaded connection between the transmission tube 30 and the docking hole 11, so that the transmission tube 30 and the shell 10 are detachable, and the operation is simple, and it is also convenient for the staff to rotate and adjust, and has better operational convenience.
[0050] As an alternative embodiment, see Figure 3 The internal thread 4 includes a first thread 4a and a second thread 4b, and the first thread 4a and the second thread 4b are spaced apart and distributed in the circumferential direction of the docking hole 11.
[0051] In order to reduce the screwing resistance and take into account the adaptability of the texture spacing of the transmission tube 30 to facilitate the adaptation and installation of the transmission tube 30 under any circumstances, the internal thread 4 arranged at the docking hole 11 in this embodiment is divided into a first thread 4a and a second thread 4b arranged at intervals, that is, a non-full thread adaptation structure is adopted.
[0052] Optionally, the first thread 4a and the second thread 4b can be designed at a 90° diagonal angle to form a thread adaptation structure. The utility model does not specifically limit the angular relationship between the first thread 4a and the second thread 4b, and any angular relationship can be formed between the two. The purpose is to be able to adapt to more models of transmission tube 30 external threads 5 to meet more installation requirements.
[0053] The embodiment of the utility model provides an antenna box 100, which can achieve threaded connection with more types of transmission tubes 30 by dividing the internal thread 4 at the docking hole 11 into a first thread 4a and a second thread 4b that are spaced apart, thereby having better installation adaptability.
[0054] As an alternative embodiment, see Figure 4 The accommodating cavity 12 includes a transfer cavity 13, and the docking hole 11 is connected to the transfer cavity 13. A plurality of threading holes 14 corresponding to the transmission lines 40 are arranged on the wall surface of the transfer cavity 13. The plurality of transmission lines 40 enter the transfer cavity 13 through the threading holes 14, gather in the transfer cavity 13, and then extend into the transmission tube 30 at the docking hole 11.
[0055] The transfer cavity 13 in the shell 10 mainly plays the role of transferring the transmission lines 40. When the transmission lines 40 are led out from the circuit board 20 in the accommodating cavity 12, it is necessary to gather the multiple transmission lines 40 into the transmission tube 30 at the docking hole 11. Therefore, the gathering process requires switching, that is, the multiple transmission lines 40 form a certain gathering radius at the transfer cavity 13. The transfer cavity 13 provides a certain space for the gathering of the transmission lines 40.
[0056] At the same time, threading holes 14 are set on the wall surface of the adapter cavity 13, so that the transmission lines 40 in the accommodating cavity 12 enter the adapter cavity 13 through the threading holes 14 for gathering, wherein the number of the threading holes 14 needs to be consistent with the number of the transmission lines 40.
[0057] An embodiment of the utility model provides an antenna box 100, which realizes the gathering process of multiple transmission lines 40 in the switching cavity 13 by setting a switching cavity 13 separated from the accommodating cavity 12 in the shell 10, and provides sufficient space for the gathering of the transmission lines 40, so that the transmission lines 40 can be better converged into the transmission tube 30, with better structural connectivity.
[0058] As an alternative embodiment, see Figure 5 A drain port 15 is provided on the surface of the shell 10 where the transfer chamber 13 is located. The drain port 15 is connected to the transfer chamber 13 and is configured to discharge the accumulated water in the transfer chamber 13 .
[0059] Considering that water may accumulate in the adapter cavity 13 after the antenna box 100 is exposed to the external environment, in order to prevent excessive accumulation of water from contacting the transmission line 40, a drain port 15 is provided in the adapter cavity 13 in this embodiment, thereby facilitating timely discharge of the accumulated water in the adapter cavity 13.
[0060] The utility model does not specifically limit the specific number, shape, size and location of the drain port 15 , as long as it can communicate with the adapter cavity 13 and discharge the internal accumulated water. The drain port 15 is usually set at the bottom of the adapter cavity 13 .
[0061] The embodiment of the utility model provides an antenna box 100, which is conducive to timely draining the internal accumulated water by setting a drain port 15 in the adapter cavity 13, preventing excessive accumulated water from interfering with the transmission line 40 and causing interruption of signal transmission. Therefore, while using the adapter cavity 13 to gather the transmission line 40, it forms a safety protection for the transmission line 40, so that the whole has better safety performance and provides reliable guarantee for the stability of transmission.
[0062] As an alternative embodiment, see Figure 4 and Figure 6The shell 10 includes a first shell 1 and a second shell 2 that are docked with each other. The first shell 1 and the second shell 2 enclose a receiving cavity 12. A first groove is provided on the surface of the first shell 1 and a second groove is provided on the surface of the second shell 2. The first groove and the second groove are docked with each other to form a docking hole 11.
[0063] In the present embodiment, the shell 10 of the antenna box 100 is configured as a split structure, that is, it is formed by a first shell 1 and a second shell 2 connected to each other. Optionally, the first shell 1 and the second shell 2 can be detachably connected to facilitate disassembly and assembly, such as by bolt connection. The utility model does not specifically limit the specific connection method of the first shell 1 and the second shell 2.
[0064] The first shell 1 and the second shell 2 are connected together to form a receiving cavity 12, so as to accommodate the circuit board 20. The shape structure of the two shells 10 determines the structure of the receiving cavity 12. As shown in the figure, the first shell 1 and the second shell 2 can adopt a square shell structure, and the two can be buckled together up and down during assembly.
[0065] Since a docking hole 11 is provided on the surface of the shell 10, a first groove and a second groove are provided on the corresponding surfaces of the first shell 1 and the second shell 2. When the two are buckled together, the first groove and the second groove are oriented toward each other to form a complete docking hole 11 as a whole, which is convenient for completing the plug-in installation of the transmission tube 30.
[0066] It can be understood that when the shell 10 has a transfer cavity 13 spaced apart from the accommodating cavity 12, since multiple transmission lines 40 need to pass through the threading holes 14 between the accommodating cavity 12 and the transfer cavity 13 and gather in the transfer cavity 13, the first shell 1 and the second shell 2 are provided with multiple corresponding grooves at the positions of the multiple threading holes 14, so that when the two are buckled up and down, the grooves can dock with each other and form a corresponding number of threading holes 14, thereby realizing the threading of multiple transmission lines 40.
[0067] The embodiment of the utility model provides an antenna box 100, which realizes the detachable function of the shell 10 by setting the shell 10 as a structural form in which the first shell 1 and the second shell 2 are connected up and down, thereby facilitating the disassembly and assembly of the antenna box 100, as well as the replacement and maintenance of the internal circuit board 20 and the transmission line 40, and has better operational flexibility.
[0068] As an alternative embodiment, see Figure 6 At least one of the first shell 1 and the second shell 2 includes a sealing groove 3, the sealing groove 3 is arranged around the accommodating cavity 12, a sealant is arranged in the sealing groove 3, and the first shell 1 and the second shell 2 are connected by the sealant.
[0069] After the shell 10 is divided into the first shell 1 and the second shell 2 , the two are connected by bolts and then sealed by a sealant therebetween, thereby further sealing and protecting the circuit board 20 and the transmission line 40 in the internal accommodating cavity 12 .
[0070] Specifically, a sealing groove 3 can be set around the first shell 1. First, a sealant is poured into the sealing groove 3. The set sealant surrounds the accommodating cavity 12. Then, the first shell 1 and the second shell 2 are connected up and down. Since the circuit board 20 and the welded transmission line 40 are pre-placed in the second shell 2, and the transmission line 40 needs to pass through the inside of the assembly shell 10, the first shell 1 and the second shell 2 will press the outer rubber of the transmission line 40, and the rubber will deform with the shape to achieve sealing. At the sealed connection between the first shell 1 and the second shell 2, the rubber of the transmission line 40 is squeezed outward and contacts the sealant from the sealing groove 3, so that a sealing effect is achieved after the sealant is cured to prevent the internal circuit board 20 from contacting the external environment.
[0071] It can be seen that the sealant between the first shell 1 and the second shell 2 can not only further connect the two and improve the stability of the connection of the shell 10, but also fill the gap between the two to achieve sealing of the internal accommodating cavity 12 and have better isolation.
[0072] The present utility model embodiment provides an antenna box 100, which realizes the sealing of the shell 10 as a whole by setting sealant in the sealing groove 3 of the first shell 1 and the second shell 2, thereby isolating the shell 10 from the external environment, preventing the external environment from causing adverse effects on the internal circuit board 20, and also improving the stability of the overall structure of the shell 10.
[0073] As an alternative embodiment, see Figure 6 The antenna box 100 includes a connector 50 , which is disposed on the housing 10 and protrudes from the housing 10 , and the antenna box 100 is connected to a predetermined component through the connector 50 .
[0074] Considering that the antenna box 100 in this embodiment needs to be connected at different positions, a connector 50 is provided on the shell 10, and a connection is formed with an external device through the connector 50. Optionally, the connector 50 may be a mounting lug protruding from the shell 10 itself, and a bolt connection is performed with the external device through the mounting lug, so that the antenna box 100 can be installed as a whole on a predetermined component, so that the antenna box 100 can work normally.
[0075] Optionally, the predetermined component may be an infrastructure such as a utility pole, and the purpose of providing the connector 50 on the housing 10 is to facilitate installation of the antenna box 100 on the predetermined component. The present invention does not specifically limit the specific type of the predetermined component.
[0076] The embodiment of the utility model provides an antenna box 100, which realizes the adaptability of the antenna box 100 to the predetermined component by setting a connector 50 on the shell 10 of the box and connecting the connector 50 to the predetermined component, so as to facilitate the staff to complete the installation of the antenna box 100 and make the antenna box 100 have better connection performance.
[0077] According to an embodiment of the utility model, a signal device is provided, including the antenna box 100 as described above.
[0078] Optionally, the signal device can be any device with an antenna capable of transmitting and receiving signals to achieve remote signal transmission, such as various infrastructure facilities, so as to cooperate with vehicle-mounted communications to improve intelligent transportation infrastructure.
[0079] The utility model embodiment provides an antenna box and a signal device, by inserting a transmission tube at the docking hole on the shell surface of the antenna box, a plurality of transmission lines led out from the circuit board inside the shell are gathered into the transmission tube for extension, thereby utilizing the transmission tube to plan and organize the plurality of transmission lines, ensuring that the transmission lines are extended while isolating and protecting them, preventing the transmission lines from being exposed to the external environment during the connection process, reducing the risk of line failure, providing reliable guarantee for forming stable and effective signal transmission, and having a better aesthetic effect while improving the overall safety performance.
