Description

Technical Field

[0001] This utility model relates to the field of cable joint technology, specifically to an anti-loosening fixing structure for cable joints. Background Technology

[0002] Cable joints are an indispensable component of cable lines, primarily used to connect two or more cables to ensure stable and continuous power or signal transmission. They play several important roles: in electrical connection, they enable reliable, low-resistance connections between cable conductors, reducing energy loss and ensuring smooth current flow; in mechanical protection, they enhance the strength of cable connections, preventing conductor breakage or insulation damage caused by external forces such as pulling or bending; and they also provide sealing, waterproofing, and moisture protection, preventing moisture intrusion that could degrade insulation performance and cause short circuits. Cable joints come in various types, categorized according to application and cable characteristics, including cold-shrink, heat-shrink, and prefabricated types. Different types of joints differ in installation methods and performance characteristics, but all must be installed strictly according to specifications to ensure their quality and reliability, thereby ensuring the safe and stable operation of the entire power system. They are a crucial link in the power transmission system.

[0003] Currently, in thermal power plants and other industrial sites, cable joints are typically connected using threaded crimping or snap-fit ​​connections. Under conditions of vibration or accidental contact during long-term cable operation, these connections are prone to loosening and slippage, potentially leading to serious consequences such as signal loss or interruption. Existing fixing methods, such as plastic cable ties and cable clamps, still suffer from insufficient stability in high-temperature, high-humidity, or violently vibrating working environments. They cannot effectively prevent cable joints from loosening in the long term and lack redundant mechanical protection measures. Therefore, we need a cable joint anti-loosening fixing structure. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-loosening fixing structure for cable joints to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable connector anti-loosening fixing structure, comprising a first cable body, a first cable head fixedly connected to one end of the first cable body, a second cable head engagedly connected to one end of the first cable head, a second cable body fixedly connected to one side of the second cable head, a reinforcing component provided on the outer wall of the first cable body, a buffer component provided on one side of the reinforcing component, a pad provided on the outer wall of the first cable body, the reinforcing component comprising a double-ended screw, a nut threadedly connected to the outer wall of the double-ended screw, a clamping plate provided on one side of the nut, an installation sleeve fixedly connected to the outer wall of the clamping plate, a threaded sleeve fixedly connected to one side of the installation sleeve, an adjusting screw threadedly connected to the inside of the threaded sleeve, an annular plate rotatably connected to one end of the adjusting screw, a fixing frame provided to one end of the adjusting screw, an annular plate provided on one side of the fixing frame, and a slot provided on the outer wall of the installation sleeve.

[0006] Preferably, the double-ended screw is fixed by nuts and clamping plates, with the nuts threadedly connected to both ends of the double-ended screw, and the clamping plates are disposed between the two nuts and in contact with the double-ended screw.

[0007] Preferably, the mounting sleeve forms a threaded structure with the adjusting screw via a threaded sleeve, and the inner diameter of the threaded sleeve matches the outer diameter of the adjusting screw, and the inner wall of the threaded sleeve fits snugly against the outer wall of the adjusting screw.

[0008] Preferably, the adjusting screw forms a locking structure with the mounting sleeve via an annular plate, and the outer diameter of the annular plate matches the inner diameter of the slot, and the outer wall of the annular plate fits against the inner wall of the slot.

[0009] Preferably, the buffer assembly includes a fixed box, which is fixed to one side of the clamping plate. A guide rod is fixedly connected inside the fixed box, a sliding sleeve is slidably connected to the outer wall of the guide rod, a spring is sleeved on the outer wall of the guide rod, a connecting rod is rotatably connected to one side of the sliding sleeve, and a connecting plate is rotatably connected to one end of the connecting rod.

[0010] Preferably, the sliding sleeve forms a sliding structure with the fixed box through the guide rod, and the outer diameter of the guide rod matches the inner diameter of the sliding sleeve, and the outer wall of the guide rod is fitted to the inner wall of the sliding sleeve.

[0011] Preferably, the sliding sleeve forms a rotating structure with the connecting plate via a connecting rod, and the two ends of the connecting rod are rotatably connected to the sliding sleeve and the connecting plate, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the anti-loosening fixing structure of this cable connector,

[0013] (1) By splicing the first cable head and the second cable head, a preliminary connection is achieved. The clamping plate, together with the double-headed screw and nut, can tightly fit and fix the two together to ensure a stable connection. After the preliminary fixation, the rotating fixing frame drives the card plate to be inserted into the slot for positioning, making the structure more stable. At the same time, the fixing frame drives the adjusting screw to rotate in the threaded sleeve, pushing the annular plate to reinforce the cable in the installation sleeve again. This series of operations are progressive and strengthen the connection strength of the cable joint from different aspects, effectively reducing the risk of cable joint detachment, ensuring the stability and safety of cable transmission, and extending the service life of the cable.

[0014] (2) During installation, the connecting plate contacts and is subjected to force, which drives the connecting rod to move. This causes the sliding sleeve to slide along the outer wall of the guide rod and compress the spring. This linkage mechanism forms a clever protection and buffering system. The elastic deformation of the spring can effectively absorb and disperse the external force generated during installation, preventing the cable from being excessively compressed. Through this buffering process, the risk of cable damage due to external impact is greatly reduced, the service life of the cable is extended, the stability of power or signal transmission is ensured, and the overall installation quality and safety are improved.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model embodiment provides an anti-loosening fixing structure for cable joints, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the cable includes a first cable body 1, a first cable head 2 fixedly connected to one end of the first cable body 1, a second cable head 3 snapped onto one end of the first cable head 2, a second cable body 4 fixedly connected to one side of the second cable head 3, a reinforcing component 5 provided on the outer wall of the first cable body 1, a buffer component 6 provided on one side of the reinforcing component 5, a pad 7 provided on the outer wall of the first cable body 1, and the reinforcing component 5 includes a double-ended screw 501, with a nut 50 threadedly connected to the outer wall of the double-ended screw 501. 2. A clamping plate 503 is provided on one side of the nut 502. An installation sleeve 504 is fixedly connected to the outer wall of the clamping plate 503. A threaded sleeve 505 is fixedly connected to one side of the installation sleeve 504. An adjusting screw 506 is threadedly connected inside the threaded sleeve 505. An annular plate 507 is rotatably connected to one end of the adjusting screw 506. A fixing bracket 508 is provided at one end of the adjusting screw 506. A retaining plate 509 is provided on one side of the fixing bracket 508. A retaining groove 510 is formed on the outer wall of the installation sleeve 504. By connecting the first cable body 1 and the second cable body 4, the first cable head 2 on the first cable body 1 can be spliced ​​with the second cable head 3 on the second cable body 4. After initial installation, the clamping plate 503 can press the pad 7, and the nuts 502 on both sides can be fastened to the outer wall of the double-ended screw 501 to fasten the clamping plate 503. This allows the first cable head 2 and the second cable head 3 to be tightly fitted and fixed. After installation, by rotating the fixing bracket 508 to one side, the fixing bracket 508 can drive the clamping plate 509 to move, so that the clamping plate 509 can be locked in the slot 510 for positioning. The fixing bracket 508 can drive the adjusting screw 506 to rotate in the threaded sleeve 505, so that the adjusting screw 506 can push the annular plate 507 to further reinforce the cable in the installation sleeve 504. This completes the reinforcement of the cable and reduces the occurrence of cable joint detachment.

[0023] Further such as Figure 3 and Figure 4As shown, the double-ended screw 501 forms a fixed structure with the nut 502 and the clamping plate 503. The nut 502 is threaded to both ends of the double-ended screw 501, and the clamping plate 503 is disposed between the two nuts 502 and in contact with the double-ended screw 501. The nuts 502 can rotate on the outer wall of the double-ended screw 501, so that the nuts 502 can fasten and install the clamping plate 503.

[0024] Further such as Figure 3 and Figure 4 As shown, the mounting sleeve 504 forms a threaded structure with the adjusting screw 506 via the threaded sleeve 505. The inner diameter of the threaded sleeve 505 matches the outer diameter of the adjusting screw 506, and the inner wall of the threaded sleeve 505 fits against the outer wall of the adjusting screw 506. The adjusting screw 506 can rotate inside the threaded sleeve 505, allowing the adjusting screw 506 to drive the annular plate 507 to clamp and fix the cable.

[0025] Further such as Figure 3 and Figure 4 As shown, the adjusting screw 506 forms a locking structure with the mounting sleeve 504 through the annular plate 507, and the outer diameter of the annular plate 507 matches the inner diameter of the slot 510. The outer wall of the annular plate 507 is fitted to the inner wall of the slot 510. Through the adjusting screw 506, the adjusting screw 506 can push the annular plate 507 to move within the mounting sleeve 504, so that the annular plates 507 on both sides can reinforce the cable.

[0026] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the buffer assembly 6 includes a fixed box 601, which is fixed to one side of the clamping plate 503. A guide rod 602 is fixedly connected inside the fixed box 601. A sliding sleeve 603 is slidably connected to the outer wall of the guide rod 602. A spring 604 is sleeved on the outer wall of the guide rod 602. A connecting rod 605 is rotatably connected to one side of the sliding sleeve 603. A connecting plate 606 is rotatably connected to one end of the connecting rod 605. During installation, the connecting plate 606 can contact the pad 7, and the connecting plate 606 can be forced to move the connecting rod 605. The connecting rod 605 can move the sliding sleeve 603, which can compress the spring 604 and slide along the outer wall of the guide rod 602. This achieves the function of protecting and buffering the cable during installation, reducing excessive compression and preventing damage to the cable.

[0027] Further such as Figure 5 As shown, the sliding sleeve 603 forms a sliding structure with the fixed box 601 through the guide rod 602, and the outer diameter of the guide rod 602 matches the inner diameter of the sliding sleeve 603. The outer wall of the guide rod 602 is fitted to the inner wall of the sliding sleeve 603. Through the sliding sleeve 603, the sliding sleeve 603 can slide along the outer wall of the guide rod 602, thereby allowing the sliding sleeve 603 to compress the spring 604.

[0028] Further such as Figure 5 As shown, the sliding sleeve 603 forms a rotating structure with the connecting plate 606 via the connecting rod 605, and the two ends of the connecting rod 605 are rotatably connected to the sliding sleeve 603 and the connecting plate 606 respectively. The sliding sleeve 603 can drive the connecting rod 605 to move when the connecting plate 606 is subjected to force, thereby enabling the connecting rod 605 to drive the sliding sleeve 603 to move.

[0029] Working principle: In use, the first cable body 1 and the second cable body 4 can be connected, allowing the first cable head 2 on the first cable body 1 to be spliced ​​with the second cable head 3 on the second cable body 4. After initial installation, the clamping plate 503 can press the pad 7, and the nuts 502 on both sides can be fastened to the outer wall of the double-ended screw 501 to secure the clamping plate 503, thus ensuring a tight fit between the first cable head 2 and the second cable head 3. Furthermore, after installation, rotating the fixing bracket 508 to one side can move the clamping plate 509, allowing it to be positioned within the slot 510. The adjusting screw 506 rotates within the threaded sleeve 505, allowing it to push the annular plate 507 to further reinforce the cable within the mounting sleeve 504. This reinforces the cable and reduces the likelihood of cable joint detachment. Furthermore, during installation, the connecting plate 606 contacts the pad 7, and the force applied to the connecting plate 606 moves the connecting rod 605. The connecting rod 605 then moves the sliding sleeve 603, which in turn compresses the spring 604 and slides along the outer wall of the guide rod 602. This provides protection and cushioning for the cable during installation, reducing excessive compression and potential damage.
