Description

Technical Field

[0001] This utility model relates to the field of waterproof cable joints, and in particular to a quick-install waterproof cable joint. Background Technology

[0002] During cable laying, it is usually necessary to connect two cables. Generally, a cable connector is used to connect the two cables together to increase the length of the cable.

[0003] In related technologies, cable joints are generally quick-release joints, typically consisting of a body that wraps around the cable joint, with locking heads installed on both sides of the body. This seals the cable joint, reducing corrosion from air and water, and minimizing the risk of electric shock. However, for the sake of sealing, the contact surface between the locking head and the cable is usually a rubber sleeve. This method leads to poor contact stability between the cable and the locking head, making the cable joint prone to shaking inside the body, which can easily cause tearing at the joint and affect the safety of the cable during use.

[0004] Therefore, it is necessary to provide a quick-install waterproof cable connector to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problem that, for the purpose of sealing, the contact surface between the locking head and the cable is made of rubber sleeve, which leads to poor contact stability between the cable and the locking head, easily causes the cable joint to shake inside the body, and is prone to tearing at the joint, thus affecting the safety of the cable during use, this utility model provides a quick-install waterproof cable joint.

[0006] The present invention provides a quick-install waterproof cable connector, comprising: a base, a terminal block fixedly connected to one side of the base, a second threaded tube fixedly connected to one side of the terminal block, a second elastic body engaged with one side surface of the second threaded tube, and the second elastic body being sleeved on the surface of the terminal block.

[0007] A first threaded tube is fixedly disposed on the side of the base away from the second threaded tube, and a first adjustable body is engaged with the side surface of the first threaded tube opposite to the base; and

[0008] Two clamping claws are fixed to one end of the first and second loosening bodies, respectively, and a waterproof adhesive core is movably disposed inside both clamping claws.

[0009] Preferably, waterproof gaskets are attached to both sides of the base, and the two waterproof gaskets are respectively sleeved on the surfaces of the first threaded tube and the second threaded tube, with the sides of the two waterproof gaskets that are far apart from each other attached to one side of the first elastic body and the second elastic body, respectively.

[0010] Preferably, the outer walls of the base, the first elastic body, and the second elastic body are all polygonal structures, and the outer diameters of the base, the first elastic body, and the second elastic body are the same.

[0011] Preferably, one side of both the first and second elastic bodies is fixedly connected with a nut, and one side of both nuts gradually tilts and contracts.

[0012] Preferably, the terminal block has wiring grooves on both sides, and the two wiring grooves are symmetrically arranged. The terminal block has two partitions fixedly connected inside, and the two partitions are located inside the wiring grooves. The two partitions are threaded with fixing bolts inside, and a chip is attached to one end of each fixing bolt.

[0013] Preferably, the chip is located at the center of the terminal block and extends to both sides, with the upper and lower sides of the chip located inside the terminal slot, respectively.

[0014] Compared with related technologies, the quick-installation waterproof cable connector provided by this utility model has the following advantages:

[0015] 1. When workers need to connect cables, they first pass the two cables through the first and second tensioning bodies respectively, and then insert them into the terminals through the first and second threaded tubes. The terminals fix one end of the two cables, and the fixed cables are energized through the terminals. The terminals are then integrated with the first and second threaded tubes and the base, which can fix one end of the two cables and reduce the stability of the cables in the first and second threaded tubes. After the cables are fixed, the workers tighten the first tensioning body to the first threaded tube, and then tighten the second tensioning body to the second threaded tube. By squeezing the clamping claws at one end of the first and second threaded tubes, the clamping claws will retract inward, squeezing the waterproof core. The contraction of the waterproof core will squeeze the internal cable, increasing the sealing of the waterproof core and the internal cable, while reducing cable shaking and pulling, reducing the passage of water vapor, and greatly increasing safety during use.

[0016] 2. The two sides of the wiring groove are respectively connected to the interior of the first threaded tube and the second threaded tube. When the worker inserts the cable, the two wiring grooves will guide the two cables, and the cable interface will be exposed in the wiring groove. Then, the worker will continuously squeeze the cable by rotating the fixing bolt to fix the cable inside the wiring groove, increasing the stability of the cable. The two cables are separated by the wiring groove. The two wiring grooves extend in opposite directions, which makes it convenient for the worker to fix the cable from different directions. When the cable is close to the bottom of the wiring groove, the cable joint will be attached to the chip. The chip is made of a metal material with good conductivity. The chip can energize the two cables and improve the installation performance. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1 to 4 A quick-install waterproof cable connector includes: a base 1, a first threaded tube 3, and clamping claws 6. A terminal 2 is fixedly connected to one side of the base 1, and a second threaded tube 5 is fixedly connected to one side of the terminal 2. A second elastic body 9 is engaged with one side surface of the second threaded tube 5 and is sleeved on the surface of the terminal 2. The first threaded tube 3 is fixedly located on the side of the base 1 away from the second threaded tube 5. The first threaded tube 3 is engaged with one side surface of the base 1 and is connected to the first elastic body 8. Two clamping claws 6 are respectively fixed to one end of the first elastic body 8 and the second elastic body 9. A waterproof adhesive core 7 is movably disposed inside each of the two clamping claws 6.

[0024] In this way, when workers need to connect the cables, they first pass the two cables through the first tensioning body 8 and the second tensioning body 9 respectively, and then insert them into the terminal block 2 through the first threaded tube 3 and the second threaded tube 5. The terminal block 2 will fix one end of the two cables. The fixed cables will be energized through the terminal block 2. Then the terminal block 2 is integrated with the first threaded tube 3, the second threaded tube 5 and the base 1, which can fix one end of the two cables by the terminal block 2 and reduce the stability of the cables in the first threaded tube 3 and the second threaded tube 5.

[0025] After the cable is secured, the worker will tighten the first loosening body 8 to the first threaded tube 3, and then tighten the second loosening body 9 to the second threaded tube 5. By squeezing the clamping claws 6 at one end of the first threaded tube 3 and the second threaded tube 5, the clamping claws 6 will retract inward, squeezing the waterproof core 7. The retraction of the waterproof core 7 will squeeze the internal cable, increasing the sealing between the waterproof core 7 and the internal cable, while reducing cable shaking and pulling, reducing the passage of water vapor, and greatly increasing safety during use.

[0026] Waterproof gaskets 4 are attached to both sides of the base 1. The two waterproof gaskets 4 are respectively fitted onto the surfaces of the first threaded tube 3 and the second threaded tube 5. The sides of the two waterproof gaskets 4 that are far apart from each other are attached to the sides of the first elastic body 8 and the second elastic body 9, respectively. During the installation process, the two waterproof gaskets 4 will slide along the surfaces of the first threaded tube 3 and the second threaded tube 5. When both waterproof gaskets 4 are attached to the base 1, the worker will tighten the first elastic body 8 and the second elastic body 9. The first elastic body 8 and the second elastic body 9 are sealed to the base 1 by the waterproof gaskets 4, reducing the passage of water vapor and increasing the waterproof performance.

[0027] Preferably, the outer walls of the base 1, the first elastic body 8, and the second elastic body 9 are all polygonal structures, and the outer diameters of the base 1, the first elastic body 8, and the second elastic body 9 are the same. When the worker installs the first elastic body 8 and the second elastic body 9, the polygonal outer wall of the base 1 can be easily clamped with tools, and then the first elastic body 8 and the second elastic body 9 can be rotated by clamping the clamp. The polygonal shape increases the surface friction and facilitates the force, making it easier to install the first elastic body 8 and the second elastic body 9.

[0028] Specifically, a nut 81 is fixedly connected to one side of both the first elastic body 8 and the second elastic body 9. One side of both nuts 81 gradually tilts and contracts. The inside of the nut 81 is arc-shaped, and the arc-shaped inner wall of the nut 81 is slightly smaller than the arc-shaped outer wall of the clamping claw 6. The surface of the clamping claw 6 is provided with square grooves at equal intervals in a ring, which can give the surface of the clamping claw 6 good deformation ability. When the nut 81 rotates, it will squeeze the clamping claw 6, and the tightness of the contact between the inside of the clamping claw 6 and the waterproof adhesive core 7 will be improved.

[0029] More specifically, wiring grooves 21 are provided on both sides of the terminal block 2, and the two wiring grooves 21 are symmetrically arranged. Two partitions 22 are fixedly connected inside the terminal block 2, and the two partitions 22 are located inside the wiring grooves 21 respectively. Fixing bolts 23 are threaded into the interior of the two partitions 22, and a chip 24 is attached to one end of each fixing bolt 23. The wiring grooves 21 inside the terminal block 2 are through grooves, and the two sides of the wiring grooves 21 are respectively connected to the interior of the first threaded tube 3 and the second threaded tube 5. When the worker inserts the cable, the two wiring grooves 21 will guide the two cables, and the cable interface will be exposed inside the wiring grooves 21. Then, the worker will continuously squeeze the cable by rotating the fixing bolts 23 to fix the cable inside the wiring grooves 21, thereby increasing the stability of the cable.

[0030] Furthermore, during implementation, chip 24 is located at the axis of terminal 2 and extends to both sides. The upper and lower sides of chip 24 are located inside the wiring groove 21 respectively. After the cable is fixed, the two cables are separated by the wiring groove 21. The two wiring grooves 21 extend in opposite directions, which makes it convenient for workers to fix the cables in different directions. When the cable is close to the bottom of the wiring groove 21, the cable joint will fit with chip 24. Chip 24 is made of metal with good conductivity. Chip 24 can energize the two cables and increase installation performance.

[0031] The working principle of the quick-install waterproof cable connector provided by this utility model is as follows:

[0032] When using the cable connectors, workers first pass the two cables through the first tensioning body 8 and the second tensioning body 9, respectively. Then, they insert them into the terminal block 2 through the first threaded tube 3 and the second threaded tube 5. The terminal block 2 secures one end of each cable. The secured cable is energized through the terminal block 2. The terminal block 2 is integrated with the first threaded tube 3, the second threaded tube 5, and the base 1, allowing the terminal block 2 to secure one end of each cable and reducing the instability of the cable within the first and second threaded tubes 3 and 5. After securing the cables, workers tighten the first tensioning body 8 and the first threaded tube 3, and then tighten the second tensioning body 9 and the second threaded tube 5. By squeezing the clamping claws 6 at one end of the first and second threaded tubes 3 and 5, the clamping claws 6 retract inward, compressing the waterproof core 7. The retraction of the waterproof core 7 further compresses the internal cable, increasing the sealing between the waterproof core 7 and the internal cable. This reduces cable movement and pulling, minimizes moisture penetration, and greatly enhances safety during use.

[0033] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
