[0025] Example 1 See Figures 1 to 5 This embodiment provides a sealed structure for a communication unit, including a housing, a PCB board 6, and wires.

[0026] The housing has an internal cavity, and at least one partition 3 is provided inside the housing. The partition 3 divides the cavity to form a receiving cavity and at least one sealing cavity. Specifically, in this embodiment, the housing includes a main housing 1 and a cover plate 2. The main housing 1 has an inner groove, and the partition 3 is disposed in the inner groove. The partition 3 divides the inner groove to form a receiving groove 4 and at least one sealing groove 5. The cover plate 2 covers the opening of the inner groove and closes the opening of the inner groove. The surface of the cover plate 2 facing the inner groove is a first surface. The first surface of the cover plate 2 cooperates with the inner groove to form the cavity of the housing, wherein the first surface of the cover plate 2 cooperates with the receiving groove 4 to form a receiving cavity, and the first surface of the cover plate 2 cooperates with the sealing groove 5 to form a sealing cavity.

[0027] A PCB board 6 is disposed within the receiving cavity, and a communication module and a SIM card are mounted on the PCB board 6. A wire is connected to the PCB board 6, with one end extending from outside the housing into the sealed cavity, passing through the partition 3, and entering the receiving cavity to electrically connect with the PCB board 6. Specifically, in this embodiment, as... Figure 1 As shown, the wires include two antennas 7 and a connecting wire 8 for connecting other devices; the housing is provided with two partitions 3, which divide the cavity of the housing into a receiving cavity and two sealed cavities. The two antennas 7 connected to the PCB board 6 extend out of the housing through the same sealed cavity, while the connecting wire 8 extends out of the housing through the other sealed cavity.

[0028] The housing has a first through hole connecting the outside and the sealed cavity, through which the wire enters the sealed cavity. In this embodiment, each wire corresponds to one first through hole; in other embodiments, multiple wires may correspond to one first through hole (i.e., multiple wires pass through the same first through hole). Sealant is provided inside the sealed cavity to seal the first through hole, thus sealing the position where the wire enters and exits the housing. Furthermore, the sealant not only serves a sealing function but also helps to secure the wire.

[0029] Furthermore, a sealing plug 9 is provided at the connection between the wire and the first through hole. The wire enters and exits the housing and is initially sealed by the sealing plug 9, and then the sealing performance is further enhanced by sealant. Specifically, in this embodiment, the sealing plug 9 includes a cylindrical body and two protrusions 11 connected to both ends of the cylindrical body and extending radially outward. For ease of description, the part of the housing with the first through hole is referred to as the first plate 10. The cylindrical body passes through the first through hole, and the two protrusions 11 are located on both sides of the first plate 10, and the two protrusions 11 cooperate to clamp the sealing plug 9 onto the first plate 10. The wire includes a wire core and a wire sheath, with the wire sheath wrapped inside the wire core. When the wire passes through the first through hole, the outer wall of the wire sheath is press-fitted with the inner wall of the cylindrical body in the sealing plug 9. The wire core enters the sealing cavity and passes through the partition 3 into the receiving cavity to be electrically connected to the PCB board 6. Moreover, the end of the wire used to connect to the PCB board 6 has its wire sheath located inside the cylindrical body and does not enter the sealing cavity; in addition, sealant is applied inside the sealing cavity. In this way, when some of the wire insulation on the outer casing is damaged, causing water to enter the insulation, the water will not enter the housing cavity and will not damage the PCB board and other components inside the housing cavity.

[0030] The partition 3 has a second through hole 12, through which the wire (specifically, the wire core) enters the receiving cavity. A sealing element 13 is provided between the wire (specifically, the wire core) and the second through hole 12. Specifically, the sealing element 13 has a first slot 15, into which the partition 3 is inserted to connect the sealing element 13 and the partition 3. The two side walls of the first slot 15 on the sealing element 13 each have a third through hole 14, which is aligned with the second through hole 12. The wire core passes sequentially through the third through hole 14 on one side wall of the first slot 15, the second through hole 12 on the partition 3, and the third through hole 14 on the other side wall of the first slot 15. The inner side wall of the third through hole 14 is press-fitted with the outer side wall of the wire (specifically, the outer side wall of the wire core). The sealing element 13 prevents sealant from entering the receiving cavity when sealant is applied to the sealing cavity.

[0031] The housing includes a main housing 1 and a cover plate 2. The main housing 1 has an inner groove. The cover plate 2 is designed to cover the opening of the inner groove and close the opening of the inner groove. This design facilitates the installation of the PCB board 6, the installation of the seal 13, and the application of adhesive into the sealing cavity (applying adhesive into the sealing cavity actually means applying adhesive into the sealing groove 5 and then closing the cover plate 2).

[0032] The cover plate 2 has a first surface and a second surface arranged opposite to each other. A step is formed around the perimeter of the second surface of the cover plate 2. The step has a blocking surface 16 facing outwards and a sealing surface 17 facing away from the first surface. The distance between the sealing surface 17 and the first surface is less than the distance between the second surface and the first surface. When the cover plate 2 closes the opening of the inner groove, the cover plate 2 is accommodated within the inner groove, and the perimeter end faces of the cover plate 2 abut against the inner walls of the inner groove (preferably an interference fit). The portion of the inner walls of the inner groove located outside the cavity and outside the cover plate 2, cooperates with the sealing surface 17 and the blocking surface 16 on the cover plate 2 to form a sealing groove 18, which contains sealant. This design of applying sealant to the sealing groove 18 serves two purposes: firstly, it seals the connection between the cover plate 2 and the inner groove opening on the main housing 1; secondly, it secures the cover plate 2 and the main housing 1.

[0033] Furthermore, the inner groove of the main housing 1 is provided with a mounting surface 19, and the first surface of the cover plate 2 is placed against the mounting surface 19; when the cover plate 2 is placed into the inner groove of the main housing 1 until the first surface of the cover plate 2 abuts against the mounting surface 19, it indicates that the cover plate 2 is in place.

[0034] More preferably, the cover plate 2 and the main housing 1 are connected by a snap-fit ​​structure, which includes a snap-fit ​​20 and a second snap-fit ​​groove 21. One of the snap-fit ​​20 and the second snap-fit ​​groove 21 is located on the first surface of the cover plate 2, and the other is located within the inner groove of the main housing 1. The snap-fit ​​structure and the sealant in the sealant groove 18 provide double fixation for the connection between the cover plate 2 and the main housing 1, making the connection more stable. Specifically, in this embodiment, the snap-fit ​​20 is connected to the first surface of the cover plate 2, and the second snap-fit ​​groove 21 is located within the inner groove of the main housing 1.

[0035] To facilitate SIM card replacement, the housing has a SIM card slot 22, which communicates with the receiving cavity. After the SIM card is inserted into the SIM card slot 22, it is electrically connected to the PCB board 6 inside the receiving cavity. A SIM card sealing plug is connected to the side of the SIM card slot 22 facing outwards from the housing, sealing the SIM card slot 22. Sealant is applied at the connection between the SIM card slot 22 and the SIM card sealing plug. That is, the SIM card is first inserted into the SIM card slot 22, then the SIM card sealing plug is inserted, and finally the sealant is applied to achieve a waterproof seal. When it is necessary to replace the SIM card, simply cut open the sealant and remove the SIM card sealing plug.

[0036] Example 2 This embodiment provides a lamp that includes the communication unit sealing structure described in Embodiment 1, and therefore possesses all the beneficial effects it has, which will not be repeated here.
