[0002] In simple cable connection processes, the cable connector is often stripped of its insulation, the copper wires are wrapped together, and then protected with insulating tape.
[0003] The above-mentioned conventional connection methods are prone to loosening. Chinese invention patent application number 202510062005.5 discloses an outdoor communication equipment cable protective connector assembly, which is equipped with a detachable protective plate and a protective pad, and a pressing component is set on the outside so that the protective pad can be pressed tightly at the cable connection. By increasing the friction at the connection, the occurrence of loosening is reduced. However, the friction force at the connection and the direction of movement are in the same straight line. After long-term use, loosening will still occur. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cable protection component that is not easy to loosen.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A cable protection assembly includes a clamping ring, which comprises a plurality of pressure blocks surrounding a predetermined cable connection point. A clamp is commonly mounted on each of the pressure blocks. Connectors are slidably connected to both sides of each pressure block. A compression block is threadedly connected to the inner side of each connector. One end of each compression block facing the clamping ring is a compression section, the diameter of which is equal to the inner diameter of the cable sheath. A protective shell is threadedly connected to the outer sides of two connectors, and the protective shell covers the outside of all the aforementioned components.
[0007] The present invention is further configured such that: the middle part of the inner side of the pressure block is an extrusion surface one, the extrusion surface one is an arc surface, the extrusion surface one is in contact with two preset cable connection points, sliders are provided on both end faces of the pressure block, and corresponding grooves are provided on the end face of the connector, the grooves are arranged radially along the connector, the sliders are slidably connected to the corresponding grooves, and shrinkage grooves exist between adjacent pressure blocks.
[0008] The present invention is further configured such that: the two sides of the extrusion surface one are extrusion surface two, the extrusion surface two is a conical surface, the outer side of the extrusion section is a corresponding conical surface, the gap between the conical surface of the extrusion section and the extrusion surface two is an extrusion groove, and the portion of the cable end extending out of the extrusion surface one is extruded in the extrusion groove.
[0009] The present invention is further configured such that: the end of the extrusion block away from the clamping ring is a connecting section, the outer wall of the connecting section is threadedly connected to the inner wall of the connector, the inner wall of the connecting section is equal to the outer diameter of the cable sheath, and a blind hole is provided on the end face of the connecting section away from the clamping ring.
[0010] The present invention is further configured such that: the protective shell includes a left shell and a right shell, the left shell and the right shell are respectively sleeved on the cables on both sides, the left shell and the right shell are respectively threaded to the outer wall of the connector on both sides, and the two facing end faces of the left shell and the right shell can abut against each other.
[0011] The advantages of this utility model are:
[0012] Several pressure blocks of the clamping ring are fixed to the outside of the cable connection by clamps, which can press the connection tightly. By increasing the friction of the wires inside the cable, the risk of the connection loosening is reduced. At the same time, the two sides of the inner wall of the clamping ring are set as the second conical extrusion surface. The connector head is threaded with an extrusion block. The inner diameter of the extrusion section of the extrusion block is equal to the inner diameter of the cable sheath. When the extrusion block is tightened, the extrusion section folds the tail of the cable end that extends out of the first extrusion surface along the second extrusion surface and presses it through the extrusion section. While maintaining a large friction force, it changes the direction of the overall friction force at the cable connection, increases the resistance to disengagement, and thus reduces the risk of disengagement.

[0021] Please see Figure 1-4 The present invention provides the following technical solution:
[0022] A cable protection assembly includes a clamping ring 1, which includes several pressure blocks 11 surrounding a pre-set cable connection. The middle part of the inner side of each pressure block 11 is a pressing surface 13, which is an arc surface that can press against the cable connection. Each pressure block 11 has a slider 15 on both ends. All sliders 15 on the same side are slidably connected to a connector 4. A groove 41 is correspondingly opened on the end face of the connector 4, which is arranged radially along the connector 4. The sliders 15 are slidably connected to the corresponding grooves 41. There is a shrinkage groove 14 between adjacent pressure blocks 11. A clamp 2 is installed on each of the pressure blocks 11. When the clamp 2 is tightened, the shrinkage groove 14 shrinks, and the pressing surfaces 13 of all pressure blocks 11 are pressed against the cable connection, increasing the friction between the wires at the cable connection and reducing the risk of detachment.
[0023] The two sides of the compression surface 13 are compression surfaces 12, which are conical. The inner side of the connector 4 is threaded with a compression block 3. The end of the compression block 3 facing the clamping ring 1 is a compression section 31. The diameter of the inner wall of the compression section 31 is equal to the inner diameter of the cable sheath. The outer side of the compression section 31 is a corresponding conical surface. The gap between the conical surface of the compression section 31 and the compression surface 12 is a compression groove. When the compression block 3 is tightened on the clamping ring 1 side, the inner wall of the compression section 31 can only accommodate the wire in a single cable. This allows the part of the cable wire extending out of the compression surface 13 on the other side to be bent into the compression groove. The wire in the compression groove extends along the outer wall of the compression section 31 until it is squeezed by the compression section 31 and the compression surface 12. This increases the bending and changes the single force direction of the cable wire at the connection, thereby increasing the resistance when it comes out and reducing the risk of the two cables coming off each other.
[0024] The end of the extrusion block 3 facing away from the clamping ring 1 is a connecting section 32. The outer wall of the connecting section 32 is threadedly connected to the inner wall of the connector 4. The inner wall of the connecting section 32 is equal to the outer diameter of the cable sheath. The connecting section 32 can slide a distance on the cable sheath, which facilitates the installation of the protective components. A blind hole is provided on the end face of the connecting section 32 facing away from the clamping ring 1, and a tool can be inserted into the blind hole to drive the extrusion block 3 to rotate.
[0025] The two connectors 4 are connected to a protective shell 5 by a common thread on their outer sides. The protective shell 5 includes a left shell 51 and a right shell 52. The left shell 51 and the right shell 52 are respectively fitted onto the cables on both sides. The left shell 51 and the right shell 52 are respectively threaded to the outer wall of the connectors 4 on both sides. The two facing end faces of the left shell 51 and the right shell 52 can abut against each other. The protective shell 5 is made of insulating material and can cover all the above-mentioned components inside, thereby achieving insulation, waterproofing and dustproofing.
[0026] Specifically, several pressure blocks 11 of the clamping ring 1 are fixed to the outside of the cable connection by the clamp 2, which can press the connection tightly. By increasing the friction of the wires inside the cable, the risk of the connection loosening is reduced. At the same time, the two sides of the inner wall of the clamping ring 1 are set as conical extrusion surfaces 12. The connector 4 is threaded with an extrusion block 3. The inner diameter of the extrusion section 31 of the extrusion block 3 is equal to the inner diameter of the cable sheath. When the extrusion block 3 is tightened, the extrusion section 31 folds the tail of the cable end that extends out of the extrusion surface 13 along the extrusion surface 12 and presses it through the extrusion section 31. While maintaining a large friction force, it changes the direction of the overall friction force at the cable connection, increases the resistance to disengagement, and thus reduces the risk of disengagement.
