[0032] like Figure 1 As shown, an embodiment of the present invention provides a cable connector 100 with temperature and humidity monitoring, which includes a connector body 110, an outer shell 120, and a cover assembly 130.

[0033] The connector body 110 is the main component for connecting two cables 200 together. Specifically, both ends of the connector body 110 are provided with interfaces, and the two cables 200 can be respectively passed through the interfaces at both ends of the connector body 110 to achieve connection.

[0034] The outer shell 120 is fitted over the connector body 110 to protect the connector body 110. The outer shell 120 may be made of copper. Additionally, in conjunction with... Figure 1 and Figure 2 An interlayer 1001 is formed between the outer shell 120 and the connector body 110, which is used to accommodate the insulating layer 140.

[0035] like Figure 2 As shown, the outer shell 120 is further provided with a through hole 121 communicating with the interlayer 1001.

[0036] It should be noted that the through hole 121 can be configured as a glue-filling hole 121a, through which workers can fill insulating glue into the interlayer 1001 so that the insulating glue forms an insulating layer 140 in the interlayer 1001.

[0037] The capping assembly 130 is used to seal the through hole 121, wherein the capping assembly 130 includes a cover body 131 and a temperature and humidity sensor 132 connected to the cover body 131. The cover body 131 seals the through hole 121 so that the temperature and humidity sensor 132 is positioned toward the interlayer 1001 or extends into the interlayer 1001.

[0038] like Figures 1 to 4 As shown, specifically, there are at least two through holes 121 and at least two capping assemblies 130. The at least two capping assemblies 130 are configured to correspond one-to-one with the at least two through holes 121. Among them, at least one through hole 121 is a potting hole 121a and at least one through hole 121 is a vent hole 121b.

[0039] Understandably, before injecting adhesive into the interlayer 1001, the injection hole 121a and the vent hole 121b can be opened. Adhesive can be injected into the interlayer 1001 through the injection hole 121a, while the existing gas in the interlayer 1001 can be discharged through the vent hole 121b. After the adhesive injection is completed, the through holes 121 can be sealed using the various sealing assemblies 130.

[0040] In the cable connector 100 with temperature and humidity monitoring of this utility model, the connector body 110 is the main component for connecting two cables 200 together. The two cables 200 can be respectively passed through both ends of the connector body 110 to achieve connection. The outer shell 120 is sleeved on the connector body 110 to protect the connector body 110. The through hole 121 on the outer shell 120 can be configured as a glue-filling hole 121a, through which workers can fill insulating glue into the interlayer 1001 to form an insulating layer 140 in the interlayer 1001. After the glue filling is completed, the through hole 121 can be sealed by the capping assembly 130 to form a seal. In the capping assembly 130 of this utility model, the temperature and humidity sensor 132 is integrated with the cap body 131. After the capping assembly 130 is installed, the temperature and humidity sensor 132 is naturally installed, and the installation process is very simple.

[0041] Furthermore, the cover assembly 130 is detachably connected to the housing 120. This facilitates the replacement of the cover assembly 130. Specifically, the cover 131 is detachably connected to the housing 120. By removing the cover 131, the temperature and humidity sensor 132 can be removed together. When installing the cover assembly 130, the temperature and humidity sensor 132 can be installed by connecting the cover 131 to the housing 120.

[0042] like Figure 2 As shown, in some embodiments, the cable connector 100 with temperature and humidity monitoring also includes a connecting cylinder 150. One end of the connecting cylinder 150 passes through the through hole 121 and is sealed to the wall of the through hole 121. The connecting cylinder 150 extends from the through hole 121 toward the outside of the outer shell 120. The internal space of the connecting cylinder 150 is in communication with the interlayer 1001. The cover 131 covers the end of the connecting cylinder 150 away from the through hole 121 and places the temperature and humidity sensor 132 inside the connecting cylinder 150.

[0043] Specifically, the connecting cylinder 150 has a cylindrical structure, with one end passing through the through hole 121 and abutting against the wall of the through hole 121, and the other end extending away from the outer casing 120. The connecting cylinder 150 and the outer casing 120 can be welded or bonded. Installing the connecting cylinder 150 on the outer casing 120 facilitates the installation of the cover assembly 130. Furthermore, the internal space of the connecting cylinder 150 can accommodate the temperature and humidity sensor 132. The temperature and humidity sensor 132, placed within the internal space of the connecting cylinder 150, can also normally detect the internal temperature and humidity conditions of the cable connector 100 with temperature and humidity monitoring.

[0044] It should be noted that there are multiple through holes 121 and multiple connecting cylinders 150, with each connecting cylinder 150 corresponding to one of the multiple through holes 121. For the multiple connecting cylinders 150, the end of each connecting cylinder 150 away from its corresponding through hole 121 is at the same horizontal position. In this way, during the glue pouring process, the risk of sealant overflowing from the lower connecting cylinder 150 can be reduced.

[0045] like Figure 2 As shown, the cover 131 further includes a sealing portion 1311 and a sleeve portion 1312 connected to the sealing portion 1311. The sleeve portion 1312 is sleeved on the connecting cylinder 150 and the sealing portion 1311 covers the end of the connecting cylinder 150 away from the through hole 121.

[0046] Understandably, the sleeve 1312 is used to connect with the connecting cylinder 150, and the capping part 1311 is used to seal the end of the connecting cylinder 150 away from the through hole 121. The sleeve 1312 is detachably connected to the connecting cylinder 150, thus enabling the entire capping assembly 130 to be detachably connected. The temperature and humidity sensor 132 can be removed together by disassembling the cap 131. When installing the capping assembly 130, the temperature and humidity sensor 132 can be installed by connecting the cap 131 to the outer casing 120.

[0047] The sleeve 1312 and the connecting cylinder 150 can be threaded together. Specifically, the inner wall of the sleeve 1312 is provided with a first thread, and the outer wall of the connecting cylinder 150 away from the through hole 121 is provided with a second thread. The sleeve 1312 is sleeved on the connecting cylinder 150 and the first thread and the second thread are connected.

[0048] like Figure 2 As shown, in some embodiments, the cap assembly 130 further includes a sealing ring 134, which is disposed between the sleeve portion 1312 and the connecting cylinder 150. This improves the sealing performance between the sleeve portion 1312 and the connecting cylinder 150. The sealing ring 134 is a rubber ring that abuts against the sleeve portion 1312 and the connecting cylinder 150, and the elasticity of the sealing ring 134 allows the cap 131 to be stably mounted on the connecting cylinder 150.

[0049] Furthermore, the inner wall of the sleeve portion 1312 is provided with an installation groove, and the sealing ring 134 is disposed in the installation groove. The installation groove is used to position the sealing ring 134 and prevent the sealing ring 134 from moving relative to the sleeve portion 1312 along the axial direction of the sleeve portion 1312.

[0050] Specifically, the mounting groove is an annular structure and is coaxially arranged with the sleeve part 1312. One part of the sealing ring 134 is embedded in the mounting groove, and the other part protrudes from the mounting groove to abut against the outer wall of the connecting cylinder 150.

[0051] like Figure 1 As shown, in some embodiments, the cover assembly 130 further includes a connector 133 connected to the inner wall of the cover body 131, and the temperature and humidity sensor 132 is connected to the connector 133; wherein, the connector 133 is a rigid member used to support the temperature and humidity sensor 132.

[0052] This utility model also provides a cable system, including the cable connector 100 with temperature and humidity monitoring as described in the above embodiment. The cable system also includes two cables 200, which are respectively connected to both ends of the connector body 110.

[0053] In the cable system of this utility model, the connector body 110 is the main component for connecting two cables 200 together. The two cables 200 can be respectively passed through both ends of the connector body 110 to achieve connection. The outer shell 120 is fitted over the connector body 110 to protect it. The through hole 121 on the outer shell 120 can be configured as a glue-filling hole 121a, through which workers can fill insulating glue into the interlayer 1001 to form an insulating layer 140 within the interlayer 1001. After the glue filling is completed, the sealing assembly 130 can be used to seal each through hole 121 to form a seal. In the sealing assembly 130 of this utility model, the temperature and humidity sensor 132 is integrated with the cover body 131. After the sealing assembly 130 is installed, the temperature and humidity sensor 132 is naturally installed, and the installation process is very simple.
