[0001] This utility model relates to the technical field of cable intermediate joint insulation protection device, and in particular to a cable intermediate joint insulation protection device. Background Technology

[0002] A cable is a power or signal transmission device consisting of one or more insulated conductors and their protective layers, used to transmit electrical energy, data, or control signals. It is a fundamental component of modern power systems, communication networks, and electronic equipment.

[0003] Existing cables require splicing during installation, and cable joints are typically connected using conductive tubing and wrapped with thick insulating tape for insulation protection. However, this method of wrapping insulating tape is not only inconvenient but also cannot guarantee the uniformity and sealing of the wrapping. Rainwater can easily seep into the cable joint, potentially causing cable damage. Therefore, existing insulation protection methods for cable joints are inconvenient. To address this, we provide an insulation protection device for cable joints. Utility Model Content

[0024] 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. Example 1

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: an insulation protection device for a cable joint, comprising: a cable body 1, a protective mechanism 2 on the outer side of the cable body 1, the protective mechanism 2 including a protective shell 21, a protective shell 22 on one side of the protective shell 21, an insulating sleeve 23 fitted onto the outer surface of the cable body 1, an O-ring 24 fitted onto the outer surface of the cable body 1, a rubber strip 26 fitted inside the protective shell 21 and the protective shell 22, a sealing groove 27 that fits the rubber strip 26 inside the protective shell 21 and the protective shell 22, and a clamping mechanism 3 on the outer side of the protective shell 21. 3 includes a clamping block 31, a clamping block 32 on one side of the clamping block 31, a fixing block 33 fixedly connected to one end of the clamping block 32, rubber pads 34 fixedly connected inside the clamping block 31 and the clamping block 32, and an O-ring seal 24 slidably connected to the cable body 1. The protective shell 21 and the protective shell 22 have mounting grooves 25 that fit the O-ring seal 24 inside. A connecting block 28 is fixedly connected to the outer surface of the protective shell 22, and a connecting block 29 is fixedly connected to the outer surface of the protective shell 21. The connecting block 29 is sleeved inside the connecting block 28, and the connecting block 29 is slidably connected to the connecting block 28.

[0026] In this embodiment, by providing a protective shell 21 and a protective shell 22, which can provide a protective enclosure for the connection of the two cable bodies 1, and whose inner sides are convex, the insulating sleeve 23 at the joint can be squeezed and fixed, so that the insulating sleeve 23 can be securely fitted onto the joint of the cable body 1. An O-ring 24 is provided, and the O-ring 24 can be installed into the mounting groove 25 opened on the protective shell 21 and the protective shell 22. Thus, the first protective shell 21 and the second protective shell 22 can compress the O-ring 24, causing the O-ring 24 to deform. This allows the O-ring 24 to fit tightly against the outer surface of the cable body 1, preventing water leakage. In addition, a rubber strip 26 is provided, which can be installed inside the first protective shell 21 and the second protective shell 22, thereby sealing and protecting the connection between the first protective shell 21 and the second protective shell 22, preventing water from entering the inside of the first protective shell 21 and the second protective shell 22. Example 2

[0027] like Figures 1-5 As shown, a locking pin 35 is sleeved inside the clamping block 31 and the fixing block 33. The locking pin 35 is slidably connected to the clamping block 31 and the fixing block 33. A limiting ring 36 is sleeved on the outer surface of the locking pin 35. The limiting ring 36 is fixedly connected to the locking pin 35. A spring 37 is sleeved on the outer surface of the locking pin 35. The two ends of the spring 37 are fixedly connected to the outer surface of the limiting ring 36 and the inner wall of the clamping block 31, respectively. A pull block 38 is fixedly connected to one end of the locking pin 35. A rotating shaft 39 is fixedly connected inside the clamping block 32. A rotating block 301 is sleeved on the outer surface of the rotating shaft 39. The rotating block 301 is rotatably connected to the connecting block 29. The rotating block 301 is fixedly connected to the clamping block 31.

[0028] In this embodiment, by setting the clamping mechanism 3, the protective shell 1 21 and the protective shell 22 can be used stably. The rotating shaft 39 and the rotating block 301 allow the clamping block 1 31 and the clamping block 2 32 to be flipped and adjusted, thereby clamping the protective shell 1 21 and the protective shell 22. At the same time, the rubber pad 34 allows the clamping block 1 31 and the clamping block 2 32 to fit tightly against the outer surface of the protective shell 1 21 and the protective shell 22, preventing movement. In addition, the locking post 35 is set, and the locking post 35 can be tightly locked into the interior of the fixing block 33 under the action of the spring 37. Thus, the clamping block 1 31 and the clamping block 2 32 can be in a stable state after they are attached.

[0029] Working principle:

[0030] like Figures 1-5As shown, in use, the insulating sleeve 23 can be first fitted onto the connection point of the two cable bodies 1, ensuring a tight connection between the insulating sleeve 23 and the cable body 1. Then, the O-ring seal 24 is fitted onto the outer surface of the cable body 1 and positioned appropriately, so that when installing the first protective shell 21 and the second protective shell 22, the O-ring seal 24 can be placed inside the mounting groove 25 opened inside the first protective shell 21 and the second protective shell 22. Before installing the first protective shell 21 and the second protective shell 22, half of the rubber strip 26 is first installed into the sealing groove 27 opened on the first protective shell 21. Then, the first protective shell 21 and the second protective shell 22 are joined together, and the other half of the rubber strip 26 is placed inside the sealing groove 27 opened on the second protective shell 22. The O-ring seal 24 will fit snugly inside the mounting groove 25 opened on the first protective shell 21 and the second protective shell 22. Simultaneously... A portion of connecting block 29 will enter the interior of connecting block 28, thereby stabilizing the protective mechanism 2 and clamping and fixing clamping blocks 31 and 32 from both sides of protective shell 21 and 22. At this time, pull block 38 is pulled first, and the pull block 38 drives the locking post 35 to slide. The locking post 35 can drive the limiting ring 36 to compress the spring 37, so that the spring 37 generates elastic force. Then clamping block 31 and clamping block 32 are connected, so that the fixing block 33 enters the interior of clamping block 31. Clamping block 31 will drive the rotating shaft 39 to rotate around the rotating block 301. Finally, pull block 38 is released, and the elastic force of spring 37 will be released instantly, and the locking post 35 will be reset, so that the locking post 35 can be tightly locked into the interior of the fixing block 33. Thus, the protective mechanism 2 is in a stable and sealed state, thereby protecting the joint of the cable body 1.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
