[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Multi-core, same-sheath branch cable, such as Figures 1-4 As shown, it includes a main cable 2 and a branch cable 3. One end of the branch cable 3 is connected to the side wall of the main cable 2 via a snap-fit assembly. The side wall of the main cable 2 is fitted with a main sheath 4, and the side wall of the branch cable 3 is fitted with a branch sheath 5. The main sheath 4 and the branch sheath 5 are located at both ends of the snap-fit assembly.
[0025] The main cable 2 and the branch cable 3 are tightly clamped together with an insulating sheath 1. Both ends of the insulating sheath 1 are fixed with locking edges 6. Locking holes are opened on the two sets of locking edges 6, and each pair of corresponding locking holes are fixed together by bolts 7.
[0026] The main cable 2 and branch cable 3 are externally protected by the main sheath 4 and the branch sheath 5. There is no sheath at the connection point between the two sets of cables. The locking assembly tightly merges one end of the branch cable 3 with the side wall of the main cable 2, connecting the branch cable 3 and the main cable 2. Then, the insulating sheath 1 is tightly fitted at the merging point. The insulating sheath 1 is bent in the middle and the two ends are butted together, so that the insulating sheath 1 seals the cable connection point. Then, it is locked by bolts 7. When there is a problem inside the branch cable, the bolts 7 can be removed to open the insulating sheath 1 for easy maintenance without damage, so that it can continue to be used.
[0027] like Figure 1 and Figure 3 As shown, the insulating sleeve 1 has a sealing groove 11 at one end and a sealing edge 10 fixed at the other end. The insulating sleeve 1 is bent in the middle, and the sealing edge 10 and the sealing groove 11 are mated together.
[0028] When the middle of the insulating sleeve 1 is bent, the two ends are locked together, and the sealing edge 10 is connected with the sealing groove 11, which increases the sealing performance of the insulating sleeve 1.
[0029] like Figure 3As shown, a shielding sleeve 12 is fixedly connected inside the insulating sheath 1. The shielding sleeve 12 is located between the sealing groove 11 and the branch sheath 5. The merging position of the main cable 2 and the branch cable 3 is located between the shielding sleeve 12.
[0030] The shielding sleeve 12 is located inside the insulating sheath 1 and provides shielding protection for the cable connection. The shielding sleeve 12 has a merging port, which is aligned with the opening of the insulating sheath 1. As the shielding sheath seals and connects the cable, the two ends of the shielding sleeve 12 are connected.
[0031] like Figure 1 and Figure 3 As shown, one end of the insulating sheath 1 is fixed with multiple sets of semi-rings 8, and every two sets of semi-rings 8 are connected to each other. The main cable 2 and the branch cable 3 are located between the semi-rings 8, and every two sets of semi-rings 8 are connected to a locking ring 9 by a common thread.
[0032] When the insulating sleeve 1 is assembled, every two sets of half rings 8 are joined together to form a ring. The locking ring 9 is threadedly connected to the joined half rings 8 to increase the firmness and sealing of the assembled insulating sleeve 1.
[0033] like Figures 2-4 As shown, the engaging assembly includes a bottom ring 13, which engages with the main cable 2. Multiple sets of elastic retaining rings 14 and 2 sets of elastic retaining rings 15 are fixedly attached to the bottom ring 13. The multiple sets of elastic retaining rings 14 and 2 sets of elastic retaining rings 15 are interleaved, and both sets of elastic retaining rings 14 and 2 sets of elastic retaining rings 15 are used to tightly connect the branch cable 3 to the main cable 2.
[0034] The snap-fit assembly tightly connects the main cable 2 and the branch cable 3. During installation, the bottom ring 13 is snapped into the main cable 2. After the branch cable 3 is tightly connected to the main cable 2, multiple sets of elastic snap rings 14 and 25 are bent to merge the branch cable 3 and the main cable 2. The multiple sets of elastic snap rings 14 and 25 are interlaced, improving the tightness.
[0035] like Figures 2-4 As shown, each of the multiple sets of elastic retaining rings 14 has a retaining groove 16 on its sidewall, and each of the multiple sets of elastic retaining rings 15 has a retaining plate 17 fixedly connected to its end, with the retaining plate 17 engaging with the retaining groove 16.
[0036] After multiple sets of elastic retaining rings 14 and 15 are bent in an alternating manner, the retaining plate 17 at the end of the elastic retaining ring 15 engages with the retaining groove 16 of the elastic retaining ring 14 to prevent the elastic retaining rings 14 and 15 from becoming loose.
[0037] The working principle of the multi-core, same-sheath branch cable provided by this utility model is as follows:
[0038] The main cable 2 and branch cable 3 are externally protected by the main sheath 4 and the branch sheath 5. There is no sheath at the connection point between the two sets of cables. The locking assembly tightly merges one end of the branch cable 3 with the side wall of the main cable 2, connecting the branch cable 3 and the main cable 2. Then, the insulating sheath 1 is tightly fitted at the merging point. The insulating sheath 1 is bent in the middle and the two ends are butted together, so that the insulating sheath 1 seals the cable connection point. Then, it is locked by bolts 7. When there is a problem inside the branch cable, the bolts 7 can be removed to open the insulating sheath 1 for easy maintenance without damage, so that it can continue to be used.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
