Description

Technical Field

[0001] This utility model relates to the field of cable joints, and in particular to a high-sealing and high-reliability protective joint. Background Technology

[0002] Cable joints, also known as cable terminations, are used to secure and fix incoming and outgoing cables after they have been laid, forming a continuous cable line. These connection points are called cable joints. Cable joints located in the middle of a cable line are called intermediate joints, while those at the ends of the line are called terminal joints. Cable joints are used to lock and secure the incoming and outgoing cables, and also serve to protect against water, dust, and vibration.

[0003] Currently, the sealing performance of existing cable joints is not good enough, resulting in poor waterproofing. Therefore, it is necessary to improve this structure to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a high-sealing and high-reliability protective connector. This utility model is achieved through the following technical solution:

[0005] A high-sealing, high-reliability protective connector includes a main sleeve, a protective tube, and a fixing ring. The main sleeve includes an inner tube, a mounting platform, and an outer tube. The mounting platform is fixedly disposed in the middle of the outer wall of the inner tube, and the outer tube is fixedly disposed on the lower surface of the mounting platform, with the outer tube and the inner tube being concentrically disposed. The fixing ring is threadedly connected to the inner tube located on the upper part of the mounting platform. A plurality of clamping blocks are evenly spaced at the lower part of the outer tube. The protective tube is located between the inner tube and the clamping blocks. When the clamping blocks are forced to deform, they will move closer to the inner tube to fix the protective tube.

[0006] In the above technical solution: the main sleeve is used to set the components of the remaining parts; the protective tube is used to protect the cable; the fixing ring is used to prevent the present invention from loosening after being connected with the intermediate joint; the inner tube is used to realize the connection, and the upper part is connected to the intermediate joint and the lower part is connected to the protective tube; the installation platform is used to realize the limiting of the protective tube during installation; the outer tube is used to set the clamping block, thereby fixing the protective tube.

[0007] A further feature of this invention is that it also includes a nut head, which is threaded onto the outer tube, and the inner wall of the nut head is provided with a pressing cone surface, which presses against the clamping block, causing the clamping block to bend and deform.

[0008] In the above technical solution: the nut head is used to force the clamping blocks to move closer to each other and fix the protective tube. Specifically, the nut head moves upward so that the abutting cone surface contacts the bottom position of the clamping block and forces the clamping block to deform inward.

[0009] A further feature of this invention is that a transverse protrusion is provided on the side of the clamping block near the protective tube, and the cross-section of the transverse protrusion is triangular.

[0010] In the above technical solution, the transverse protrusion allows the clamping block to contact and clamp the protective tube with minimal deformation.

[0011] A further feature of this invention is that a rubber ring is fitted onto the inner tube on the upper part of the mounting platform.

[0012] In the above technical solution: the rubber ring is used to prevent the fixed ring from easily shifting after rotating to the lowest position.

[0013] A further feature of this invention is that a plurality of friction strips are evenly distributed on the side of the fixing ring near the mounting platform.

[0014] In the above technical solution: the friction strip is used to further increase the friction force, making it less likely for the fixed block to shift after contacting the rubber ring.

[0015] A further feature of this invention is that the inner diameter of the protective tube is the same as the outer diameter of the inner tube.

[0016] In the above technical solution, the inner diameter of the protective tube is the same as the outer diameter of the inner tube, which is used to improve the sealing performance.

[0017] This utility model discloses a high-sealing and high-reliability protective connector, which, compared with the prior art:

[0018] 1. By setting a fixing ring, this utility model allows the fixing ring to rotate and abut against the nut of the intermediate joint after being connected with the intermediate joint, making it difficult for the nut of the intermediate joint to rotate and loosen, thereby improving the sealing performance and reliability.

[0019] 2. This utility model also improves the sealing performance by setting up rubber rings and friction strips, making it less likely for the fixing ring to shift and loosen.

[0020] 3. The present invention also makes it easier to fix and disassemble the protective tube by setting up clamping blocks and nut heads. Attached Figure Description
