[0028] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0029] The quick-connect structure for aluminum sheathed wire cores provided in the embodiments of this application will now be described. A quick-connect structure for aluminum sheathed wire cores, such as... Figures 1-3 As shown, it includes a first aluminum wire core 1 and a second aluminum wire core 2. Both the first aluminum wire core 1 and the second aluminum wire core 2 are connected to locking components, and the two locking components are connected by a connecting component.
[0030] The two locking components have the same structure. Here, we take the locking component connected to the first aluminum sheath core 1 as an example.
[0031] Specifically, the locking assembly includes an inner sleeve 3, a locking threaded sleeve 4, and a locking cover 5. The first aluminum protective core 1 is fitted with a cone-shaped inner sleeve 3, the inner sleeve 3 is fitted with a locking threaded sleeve 4, and the locking threaded sleeve 4 is fitted with a locking cover 5. The locking threaded sleeve 4 is flared and has four V-shaped grooves 6 at its end. As the locking cover 5 is tightened with the locking threaded sleeve 4, the four V-shaped grooves 6 of the locking threaded sleeve 4 continuously contract, squeezing the inner sleeve 3 and thus clamping the first aluminum protective core 1.
[0032] The connecting assembly includes a first connecting end 7, a second connecting end 8, a threaded connecting sleeve 9, and a connecting pin 10. The first aluminum wire core 1 is connected to the locking cover 5, which is connected to the first connecting end 7. The first connecting end 7 is connected to the threaded connecting sleeve 9. The second aluminum wire core 2 is connected to the locking cover 5, which is connected to the second connecting end 8. The threaded connecting sleeve 9 and the second connecting end 8 are connected by the connecting pin 10.
[0033] Among them, such as Figures 3-4As shown, the locking threaded sleeve 4 is provided with a first external thread 12, and the rear end of the locking cover 5 is provided with a first internal thread 13. The locking threaded sleeve 4 and the locking cover 5 are threadedly connected by the first external thread 12 and the first internal thread 13. As the locking cover 5 and the locking threaded sleeve 4 are screwed together, the four V-shaped slots 6V of the locking threaded sleeve 4 continuously contract, squeezing the inner liner 3, and thus clamping the first aluminum protective core 1.
[0034] Furthermore, such as Figures 4-5 As shown, the front end of the locking cover 5 is provided with a second internal thread 15, and the rear end of the first connecting end 7 is provided with a second external thread 14. The locking threaded sleeve 4 is threadedly connected to the first connecting end 7 by the cooperation of the second internal thread 15 and the second external thread 14.
[0035] Furthermore, such as Figures 5-6 As shown, the front end of the first connecting end 7 is provided with a third external thread 16, and the rear end of the threaded connecting sleeve 9 is provided with a third internal thread 17. The first connecting end 7 and the threaded connecting sleeve 9 are threadedly connected by the cooperation of the third internal thread 17 and the third external thread 16.
[0036] Among them, such as Figure 2 and Figure 8 As shown, a threaded retaining ring 11 is provided between the threaded connecting sleeve 9 and the first connecting end 7. The threaded retaining ring 11 has a fourth internal thread 19, and the connecting pin 10 has a fourth external thread 18. The fourth internal thread 19 and the fourth external thread 18 cooperate to fit the threaded retaining ring 11 onto the connecting pin 10. Since the threaded retaining ring 11 is located inside the threaded connecting sleeve 9, the connecting pin 10 is connected to the threaded connecting sleeve 9 through the above structure.
[0037] Furthermore, the threaded connecting sleeve 9 has a first through hole 21 at its rear end and a second through hole 22 at its front end. The two ends of the connecting pin 10 are respectively located in the first through hole 21 and the second through hole 22, connecting the second connecting end 8 and the threaded connecting sleeve 9.
[0038] Furthermore, such as Figure 7 As shown, the rear end of the second connecting end 8 is provided with a fifth external thread 20, which is used to engage with the second internal thread 15 of the locking cover 5 connected to the second aluminum wire core 2, so as to connect the second connecting end 8 and the locking cover 5 connected to the second aluminum wire core 2.
[0039] The working principle of this utility model is as follows:
[0040] When it is necessary to connect the first aluminum wire core 1 and the second aluminum wire core 2, firstly connect a locking component to the first aluminum wire core 1. Specifically, fix the inner sleeve 3 to the first aluminum wire core 1. After fixing, fix the locking threaded sleeve 4 to the outside of the inner sleeve 3. Put the locking cover 5 into the outside of the locking threaded sleeve 4 and rotate the locking cover 5 to connect the locking component to the first aluminum wire core 1.
[0041] Next, the first connecting end 7 is connected to the locking cover 5 of the first aluminum wire core 1. Similarly, the other locking component is connected to the second aluminum wire core 2.
[0042] Finally, insert the connecting pin 10 into the second connecting end 8, connect the second connecting end 8 to the locking cover 5 of the second aluminum wire core 1, insert the threaded retaining ring 11 into the threaded connecting sleeve 9, connect the connecting pin 10 to the threaded retaining ring 11, and then connect it to the threaded connecting sleeve 9. Connect the threaded connecting sleeve 9 to the first connecting end 7, thereby connecting the first aluminum wire core 1 and the second aluminum wire core 2.
[0043] This invention features a simple structure and convenient operation. Through the cooperation of the locking and connecting components, the connection process is simplified, enabling rapid connection of the first aluminum sheath core 1 and the second aluminum sheath core 2. During the use of the connected aluminum sheath cores, the connecting portion receives tensile force. This force primarily acts on the locking threaded sleeve 4. The inner wall of the locking threaded sleeve 4 and the outer wall of the inner bushing 3 are conically pressed together. Under tension, the clamping force of the inner bushing 3 on the aluminum sheath core increases with the pulling force. This avoids the possibility of connection detachment due to differences in connection position or surface slippage in traditional traction methods, ensuring the continuity of the cable conductor production process. Furthermore, it ensures the continuity of the cable conductor production process, eliminating the need for frequent shutdowns, reducing the consumption of excessive raw materials due to restarting, reducing the number of personnel and physical exertion required by traditional connection methods, simplifying the entire cable connection process, improving overall production efficiency, and reducing production costs.
[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
