Description

Technical Field

[0001] The utility model relates to the technical field of temperature-sensing cables, in particular to a waterproof temperature-sensing cable terminal device. Background Art

[0002] In fields such as power, communications, and industrial automation, waterproof and temperature-sensitive cable terminal devices play a vital role. Such devices are not only required to have excellent waterproof performance, but also to be able to monitor the temperature changes of the cable in real time to ensure the safe and stable operation of the cable system.

[0003] A common waterproofing measure is to use threaded fasteners inside the cable terminal and add sealing rings at the bolted joints. The use of sealing rings effectively prevents moisture from penetrating into the device through the bolted joints, thus ensuring the device's waterproof performance.

[0004] However, due to the presence of the sealing ring, the bolt will encounter greater friction resistance when screwing into the threaded hole, making it difficult for the bolt to completely reach the bottom of the threaded hole and achieve tight fixation. During subsequent use, if the bolt becomes loose due to external interference or vibration, the sealing effect of the sealing ring will be destroyed, allowing water to enter the device. The existing practice is to customize the bolts for different threaded holes to ensure that the bolts can be smoothly screwed into the threaded holes and achieve the expected tightening effect. However, this practice not only increases the production cost of the device, but also reduces production efficiency, which is not conducive to large-scale production and application.

[0005] In view of this, this application is hereby filed. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1 - Figure 6 , the utility model provides a technical solution: a waterproof temperature-sensing cable terminal device, comprising a housing 1 and a sealing plate 6, wherein an opening and closing device is fixedly installed on the side wall of the sealing plate 6;

[0026] The opening and closing device includes a bracket 16 fixedly mounted on the side wall of the sealing plate 6, a broken gear 8 fixedly mounted on the end of the bracket 16 away from the sealing plate 6, a connecting rod 9 fixedly mounted on the outer wall of the broken gear 8 away from the bracket 16, a connecting column 10 rotatably mounted on the end of the connecting rod 9 away from the broken gear 8, a connecting rod 2 11 fixedly mounted on the side wall of the connecting column 10, a broken gear 5 26 fixedly mounted on the end of the connecting rod 2 11 away from the connecting column 10, and a broken gear 4 meshingly connected to the outer wall of the broken gear 5 26. 25. The outer wall of the broken gear four 25 is fixedly installed with a bracket two 17. The outer wall of the broken gear four 25 close to the bracket two 17 is fixedly installed with a connecting rod three 12. The end of the connecting rod three 12 away from the broken gear four 25 is rotatably installed with a connecting column two 13. The side wall of the connecting column two 13 is fixedly installed with a connecting rod four 14. The end of the connecting rod four 14 away from the connecting column two 13 is fixedly installed with a broken gear two 21. The outer wall of the broken gear two 21 is meshedly connected with the broken gear three 22. The outer wall of the broken gear three 22 is fixedly installed with a bracket three 18.

[0027] It should be noted that: through the meshing between the incomplete gears and the transmission of the connecting rod, a simple pulling action can be converted into the coordinated movement of multiple components, thereby achieving smooth opening and closing of the sealing plate 6, which not only improves the convenience of operation, but also effectively ensures the sealing performance of the device.

[0028] See also Figure 4 The utility model provides a technical solution: a waterproof temperature-sensing cable terminal device, comprising a broken gear four 25, on the inner wall of which a rotating shaft three 28 is rotatably mounted, a connecting plate one 15 is fixedly mounted on the side wall of the rotating shaft three 28, an end portion of the connecting plate one 15 and the rotating shaft three 28 located in the same plane is fixedly mounted with a rotating shaft two 27, and the rotating shaft two 27 is rotatably mounted on the inner wall of the broken gear five 26 away from the outer wall of the connecting plate one 15.

[0029] See also Figure 1 、 Figure 3 The utility model provides a technical solution: a waterproof temperature-sensing cable terminal device, comprising a fixed column 23 rotatably mounted on the inner wall of a broken gear 3 22, a connecting plate 2 19 fixedly mounted on the side wall of the fixed column 1 23, a rotating shaft 24 fixedly mounted on the surface of the connecting plate 2 19 and the fixed column 1 23 in the same plane, and the rotating shaft 24 rotatably mounted on the inner wall of the broken gear 2 21.

[0030] It should be noted that due to the presence of the connecting plate 2 19, the meshing relationship between the incomplete gear 4 25 and the incomplete gear 5 26 is more stable. Even in the case of external interference or load changes, the two incomplete gears can maintain close meshing and are not prone to misalignment or disengagement.

[0031] See also Figure 2 、 Figure 4 The utility model provides a technical solution: a waterproof temperature-sensing cable terminal device, including a fixing column 23 with a limit plate 7 fixedly installed at the end away from the connecting plate 19, and a sliding groove 20 is opened on the inner wall of the limit plate 7.

[0032] It should be noted that the slide groove 20 enables the components used in conjunction with the slide groove 20 to move smoothly and accurately along a predetermined trajectory, which helps to maintain the accurate and consistent movement relationship between the various components and avoids failures caused by poor movement or misalignment of components.

[0033] See also Figure 4 The utility model provides a technical solution: a waterproof temperature-sensing cable terminal device, including a plurality of sliding columns 32 slidably installed on the inner wall of a slide groove 20, and the plurality of sliding columns 32 are respectively fixedly connected to the incomplete gear 1 8, the rotating shaft 2 27, the rotating shaft 3 28 and the end of the rotating shaft 1 24.

[0034] It should be noted that the multiple sliding columns 32 slidably installed on the inner wall of the second slide groove 20 ensure the smooth sliding of each component during movement, reduce the resistance and wear caused by friction, and thus improve the mechanical efficiency and durability of the entire opening and closing device.

[0035] See also Figure 5 The utility model provides a technical solution: a waterproof temperature-sensing cable terminal device, comprising a pull column 3 rotatably installed on the inner wall of a broken gear 8, and the pull column 3 is slidably installed on the inner wall of a slide groove 2 opened on the side wall of the shell 1.

[0036] It should be noted that the design in which the pull post 3 is slidably mounted on the inner wall of the slide groove 2 provided on the side wall of the housing 1 realizes a stable and flexible connection between the opening and closing device and the housing 1, allowing the operator to drive the movement of the opening and closing device by pulling the pull post 3, thereby controlling the opening and closing of the sealing plate 6;

[0037] Furthermore, a sliding plate can be provided on the inner wall of the slide groove 2, and the sliding plate is fixedly connected to the pull column 3, which can play a sealing role and effectively prevent moisture or other impurities from entering the interior of the device through the slide groove 2, thereby ensuring the waterproof performance of the device and the safe operation of the internal components.

[0038] See also Figure 5The utility model provides a technical solution: a waterproof temperature-sensing cable terminal device, comprising a housing 1 with a fixed column 29 fixedly mounted on the side wall near a slide groove 2, a clamping plate 30 rotatably mounted on the outer wall of the fixed column 29, and an arc-shaped clamping ring 31 fixedly mounted on the end of the clamping plate 30 away from the fixed column 29.

[0039] It should be noted that the second fixed column 29 serves as a support point, allowing the clamping plate 30 to rotate within a certain range, and the arc-shaped clamping ring 31 at the far end of the clamping plate 30 can cooperate with the pull column 3 to achieve a stable locking of the sealing plate 6;

[0040] Furthermore, when the sealing plate 6 needs to be opened, the operator can move the clamping plate 30 to separate the arc-shaped clamping ring 31 from the pull column 3, thereby releasing the locked state. When the sealing plate 6 needs to be closed and locked, the operator only needs to re-insert the arc-shaped clamping ring 31 into the outer wall of the pull column 3.

[0041] See also Figure 6 The utility model provides a technical solution: a waterproof temperature-sensing cable terminal device, comprising a housing 1 with a cable connection pipe 4 fixedly mounted on the top, a sealing ring 5 fixedly mounted on the bottom of the housing 1, and an integrally formed anti-slip pattern on the surface of the sealing ring 5.

[0042] It should be noted that the sealing ring 5 installed at the bottom of the housing 1 effectively enhances the waterproof performance of the device. The one-piece anti-slip grooves on the surface not only increase the friction between the sealing ring 5 and the sealing plate 6, preventing the device from loosening or displacement due to external factors, but also further improves the stability and safety of the device.

[0043] Working principle: When it is necessary to inspect the inside of the device, the operator only needs to simply turn the arc-shaped clamping ring 31 to pull it up, and then pull the pull column 3 to slide along the slide groove 2 to start the entire opening and closing device. The movement of the pull column 3 drives the rotation of the broken gear 8. This action is transmitted through the connecting rod 1 9, the connecting rod 2 11, the connecting rod 3 12 and the connecting rod 4 14, so that the broken gear 2 21, the broken gear 3 22, the broken gear 4 25 and the broken gear 5 26 rotate in sequence. The rotation of these gears drives the synchronous movement of the bracket 16, the bracket 2 17 and the bracket 3 18, so that the sealing plate 6 can be opened smoothly perpendicular to the bottom of the shell 1, providing operating space for the maintenance personnel. After the inspection is completed, the operator only needs to pull the pull column 3 in the opposite direction to reclose the sealing plate 6 through the linkage of the gears and the connecting rod. At this time, the arc-shaped clamping ring 31 is stuck on the outer wall of the pull column 3 to ensure the overall sealing of the device, prevent moisture and other impurities from entering the interior of the device, and ensure the normal operation of the cable terminal device.
