[0034] Example

[0035] like Figure 1-4 As shown, the present application proposes a cable protection tube for cable connection, comprising a first protection tube 1 and a second protection tube 2, and also comprising a connection end protective member 3 arranged at one end close to each other of the first protection tube 1 and the second protection tube 2, for accommodating the cable at the connection end to prevent the cable connection end from being exposed to the outside and damaged by corrosion.

[0036] The connecting end protection member 3 includes a first protective cover 31 fixedly mounted on the end of the second protective tube 2 and a second protective cover 32 slidably mounted on the end of the first protective tube 1. The first protective cover 31 and the second protective cover 32 are fixed by a positioning mechanism 7. The ends of the first protective cover 31 and the second protective cover 32 that are close to each other are fixedly connected to a waterproof pad 33. The waterproof pad 33 is made of silicone material. When the two waterproof pads 33 are tightly attached, they play a waterproof role, so that the connecting end of the cable maintains a waterproof storage space. It should be noted that the inner diameter of the first protective cover 31 and the second protective cover 32 is larger than the inner diameter of the first protective tube 1 and the second protective tube 2, so that the connecting end of the cable core has sufficient storage space, because the storage space of the cable connector is larger than the storage space of the complete cable.

[0037] Furthermore, the inner wall of the first protective cover 31 is connected to a wire board 5 located at the end of the second protective tube 2 for combing the cable cores. The cross section of the wire board 5 is provided with a plurality of wire holes 6 for passing the cable cores to avoid the connected cores from being tangled.

[0038] In this embodiment, a plurality of limiting protrusions 42 are connected to one end of the outer wall of the first protective tube 1 close to the second protective tube 2, and a plurality of limiting grooves 41 are provided at the sliding end of the second protective cover 32. When the first protective cover 31 is connected to the second protective cover 32, the plurality of limiting protrusions 42 are respectively connected to the plurality of limiting grooves 41, wherein the limiting grooves 41 can play a role of limiting the movement of the limiting protrusions 42, thereby preventing the second protective cover 32 from separating from the end of the first protective tube 1, so that the second protective cover 32 and the first protective tube 1 have a stable connection state.

[0039] Specifically, the positioning mechanism 7 includes a positioning bar 71 that extends through and plugs into the inner wall of the second protective cover 32. A screw 73 is threadedly connected to the positioning bar 71. The screw 73 is longer than the positioning bar 71, and a torsion block 74 is fixedly connected to the end of the screw 73 to facilitate rotation of the screw 73 during operation. A slide bar 72 is fixedly connected to the inner wall of the positioning bar 71, and a groove is defined in the side wall of the first protective tube 1 for the slide bar 72 to slide. A fixed block 75 is fixedly connected to the end of the first protective cover 31. The fixed block 75 extends through the first protective cover 31, and the inner end surface of the fixed block 75 is flush with the inner end surface of the first protective cover 31. A threaded groove is defined at the inner end of the fixed block 75. The external threads of the screw 73 mate with the internal threads of the groove. When the screw 73 is inserted into the threaded groove at the end of the fixed block 75, the first and second protective covers 31 and 32 are positioned, allowing the first and second protective covers 31 and 32 to fit together. A groove penetrating the corresponding waterproof pad 33 is formed at the end of the first protective cover 31, and a positioning protrusion matching the groove is fixedly connected to the end of the other waterproof pad 33. When the positioning protrusion is inserted into the groove, the screw 73 is aligned with the threaded groove at the end of the fixing block 75.

[0040] The principle of this embodiment is as follows: two sections of cables are located in the first protective tube 1 and the second protective tube 2, respectively. When the ends of the two sections of cables need to be connected, the second protective cover 32 is first moved to one side to facilitate the operation and connection of the ends of the two sections of cables. After the cable connection is completed, the second protective cover 32 is slid toward the first protective cover 31, so that the waterproof pads 33 near one end of the first protective cover 31 and the second protective cover 32 are in contact with each other. At this time, the inner ends of the two positioning bars 71 are in contact with the two fixing blocks 75 respectively (the first protective cover 31 and the second protective cover 32 are in contact with each other). When the positioning protrusion is inserted into the groove of the corresponding waterproof pad 33, the first protective cover 31 and the second protective cover 32 can be accurately positioned). In the next step, the torsion block 74 is rotated to insert the end of the screw 73 into the threaded groove at the inner end of the fixing block 75, thereby positioning the first protective cover 31 and the second protective cover 32, so that the connecting end of the cable is accommodated on the inner side of the first protective cover 31 and the second protective cover 32, thereby protecting the connecting end of the cable. In this embodiment, the structure of the positioning mechanism 7 also facilitates the disassembly of the first protective cover 31 and the second protective cover 32.

[0041] In this application, a wire plate 5 is set on the inner wall of the first protective cover 31, and several wire holes 6 are opened on the side wall of the wire plate 5, which can comb the cable cores, avoid confusion of the wire cores at the connection end, and facilitate later maintenance or repair.

[0042] The above specific embodiments are merely preferred embodiments of the present application. Based on the technical solutions of the present application and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations of the above specific embodiments. The above specific embodiments are merely explanations of the present application and are not limitations of the present application.
