[0027] To better understand the purpose, structure, and function of the present utility model, the following further describes in detail a cable indoor terminal structure of the present utility model with reference to the accompanying drawings.

[0028] As Figures 1-4 shown, a cable indoor terminal structure of the present utility model includes a fixing plate 1, a cable core 2, and a cable line 3. The cable core 2 is fixedly connected to the cable line 3. A sliding opening 5 is formed on the surface of the fixing plate 1. A fixing block 11 is inserted into the inner side of the sliding opening 5. A second through hole 10 is formed on the surface of the fixing block 11. A nut 14 is inserted into the inner side of the second through hole 10. A sliding groove 8 is formed on the surface of the fixing plate 1. A circular slider 9 is arranged inside the sliding groove 8. The fixing block 11 is fixedly connected to the surface of the circular slider 9. In this way, the fixing block 11 and the slider can slide in the sliding groove 8 and the through holes, so as to adjust the position of the cable core 2 to connect different devices, which greatly improves the practicability of the device. A fixing sleeve 12 is attached to the surface of the fixing block 11. A third through hole 13 is formed on the surface of the fixing sleeve 12. The nut 14 is inserted into the inner side of the third through hole 13. The nut 14 is inserted into the surface of the second through hole 10. The cable core 2 is inserted into the inner side of the fixing sleeve 12. In this way, tightening the nut 14 can stably fix the cable core 2 on the fixing plate 1, thereby avoiding the loosening of the connection due to the shaking of the cable core 2.

[0029] A drying ring 21 is sleeved on the surface of the cable core 2, and a sealing sleeve 15 is sleeved on the surface of the cable core 2. The top of the sealing sleeve 15 is fixedly connected to a sealed drying box body 7. The top of the sealed drying box body 7 is sleeved with a sealed drying box cover 17. A fourth perforation 22 is opened on the surface of the sealed drying box cover 17. A rubber plug 16 is inserted into the inner side of the fourth perforation 22. In this way, when in use, the rubber plug 16 is pulled out, and the connecting device is inserted into the fourth perforation 22 to be connected to the terminal 20. The connection is inside the sealed drying box body 7, and a drying ring 21 is provided on the surface of the cable core 2. In this way, the connection can also be kept dry during use, thereby increasing the service life of the device. When storing, only the rubber plug 16 needs to be inserted into the fourth perforation 22 to complete the sealing, which greatly improves the service life of the device.

[0030] A first perforation 6 is opened on the surface of the fixing plate 1. The number of the first perforations 6 is four. The structure of the four first perforations 6 can improve the fixing stability of the fixing plate 1.

[0031] A three-core finger sleeve 4 is sleeved on the surface of the cable core 2, and a three-core finger sleeve 4 is sleeved on the surface of the cable 3. It is made of a composite of cross-linked polyolefin material and hot melt adhesive and is sleeved at the branch of the cable core 2. It shrinks when heated, playing a role in waterproofing, moisture-proofing and sealing protection.

[0032] Terminals 20 are provided at the top of the cable core 2. The number of the terminals 20 is three. The structure of the terminals 20 facilitates the connection of the cable structure to the connection device, improving the practicability of the device.

[0033] A handle 18 is fixedly connected to the top of the rubber plug 16. A sealing ring 19 is adhesively bonded to the inner side of the sealed drying box cover 17. The structure of the sealing ring 19 makes the connection between the sealed drying box cover 17 and the sealed drying box body 7 tighter, thereby improving the sealing effect.

[0034] Working principle of the indoor cable terminal structure: When the cable terminal structure needs to be connected to the equipment, first connect the fixing plate 1 under the connecting equipment through thread connection. Then loosen the nut 14 to adjust the distance between the cable cores 2, so as to adjust according to the position of the connection. After adjustment, insert the cable core 2 into the inner side of the fixing sleeve 12. Then, after connecting the terminal 20 to the connection point, tighten the nut 14 to complete the fixation. In this way, the device can adapt to connection equipment with different distances, and tightening the nut 14 can fix the cable core 2 relatively stably on the fixing plate 1, thus avoiding the loosening of the connection point caused by the shaking of the cable core 2. When the cable terminal structure needs to be used, first sleeved the sealing sleeve 15 at the bottom of the sealed drying box body 7 on the surface of the cable core 2, slide it down to expose the terminal 20, pull out the rubber plug 16, insert the connecting equipment into the fourth through hole 22 to connect with the terminal 20, and finally sleeve the sealed drying box cover 17 on the surface of the sealed drying box body 7. In this way, a relatively sealed shell is formed to wrap the connection point. And a drying ring 21 is provided at the connection of the terminal 20, which can further keep the connection point dry, thus preventing rusting caused by moisture at the connection point and increasing the service life of the device. When storing the cable terminal, just disconnect the connection point and insert the rubber plug 16 into the fourth through hole 22 to form a sealed structure to prevent the terminal 20 from rusting.
