Description

Technical Field

[0001] This utility model relates to the technical field of communication base station supporting equipment, and in particular to a waterproof connector for communication base stations. Background Technology

[0002] Communication base stations are mostly deployed in outdoor environments, often facing complex conditions such as alternating high and low temperatures, rain and snow, moisture accumulation, and dust adhesion. Their signal transmission lines need to be connected in segments through connectors, and the waterproof and sealing performance of the connectors directly determines the stability of base station signal transmission. If rainwater or moisture seeps into the connector, it can easily cause short circuits and signal attenuation, leading to problems such as interrupted calls and data transmission delays. It can also corrode the internal metal contacts, induce failures in the core equipment of the base station, significantly increase the frequency and cost of maintenance, and in severe cases, even affect the continuity of regional communication network coverage.

[0003] Existing waterproof connectors generally use threaded engagement to fix cables. This structure has obvious technical limitations. A certain torque needs to be applied during the thread tightening process, which can easily lead to uneven stress on the outer insulation layer of the cable. Especially for thin-walled flexible cables, local compression deformation, cracking and other damages are likely to occur, which will damage the original protective performance of the cable, make poor contact between the cable and the connector, aggravate signal loss, shorten the overall service life of the connector and cable, and increase the long-term operating cost of the base station.

[0004] Therefore, a waterproof connector for communication base stations needs to be designed. Utility Model Content

[0005] In order to overcome the shortcomings of existing waterproof connectors that use threaded engagement to fix cables, which can easily lead to uneven stress on the insulation layer of thin-walled cables, causing extrusion deformation, cracking, and shortening service life, this utility model provides a waterproof connector for communication base stations.

[0006] The technical implementation scheme of this utility model is as follows: A waterproof connector for a communication base station includes a male connector, a female connector, a connecting ring, a collar, a connecting ring, a clamping plate, a connecting block, a bidirectional screw, and a screw head. The male connector is snapped into the bottom of the female connector. Both the male and female connectors are threaded with connecting rings on their outer sides. The connecting rings are threaded with collars on their outer sides. Multiple connecting rings are fixedly connected to the opposite sides of the male and female connectors. Two clamping plates are slidably connected inside each connecting ring. A connecting block is fixedly connected to the opposite sides of the two clamping plates on the same connecting ring. A bidirectional screw is rotatably connected to the outer side of each connecting ring. The connecting blocks are threadedly connected to the corresponding bidirectional screws. A screw head is fixedly connected to one side of each bidirectional screw.

[0007] Furthermore, it is particularly preferred that a sealing ring is also included, with both the male and female connectors having a sealing ring fixedly connected to them.

[0008] Furthermore, it is particularly preferred that the connector also includes locking blocks, with multiple locking blocks fixedly connected to the lower external end of the male connector.

[0009] In addition, it is particularly preferred that the connector also includes a retaining ring, which is fixedly connected to the outside of the female connector. The retaining ring has multiple slots, and the retaining blocks are engaged in the corresponding slots.

[0010] Furthermore, it is particularly preferred that the ring also includes elastic sheets, with multiple elastic sheets fixedly connected inside each connecting ring.

[0011] In addition, it is particularly preferred that the card blocks are all made of engineering plastics.

[0012] The beneficial effects of this utility model are: 1. By rotating the bidirectional screw, the clamping plate is driven to move radially, achieving a uniform and controllable clamping force on the cable. This avoids the cable from loosening due to pulling and also prevents excessive tightness from damaging the insulation layer. It solves the problem that existing waterproof connectors use threaded engagement to fix cables, which easily leads to uneven stress on the insulation layer of thin-walled cables, causing compression deformation, cracking, and shortening service life.

[0013] 2. By setting up a locking block and a retaining ring, the male connector and the female connector are connected by the locking block and the retaining ring to limit radial displacement, ensure axis coincidence, avoid wear and poor contact caused by misalignment of conductive terminals, extend the service life of terminals, and further ensure the continuity of communication links.

Detailed Implementation

[0023] A waterproof connector for a communication base station, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the connection includes a male connector 1, a female connector 2, a connecting ring 3, a collar 4, a connecting ring 5, a clamping plate 6, a connecting block 7, a bidirectional screw 8, and a screw head 9. The male connector 1 is snapped into the bottom of the female connector 2. Both the male connector 1 and the female connector 2 are threadedly connected to the external parts of the connecting ring 3. The connecting ring 3 is also threadedly connected to the external parts of the collar 4. The collar 4 protects the threads of the connecting ring 3 from outdoor ultraviolet rays and rainwater erosion. On the other hand, it can form an anti-loosening constraint on the connecting ring 3 through its own thread pre-tightening force, preventing the threads of the connecting ring 3 from loosening due to long-term vibration, and further improving the stability of the overall connection. Four connecting rings 5 ​​are welded to the opposite sides of the male connector 1 and the female connector 2, which are distributed axially. Inside each connecting ring 5, there are two symmetrically distributed clamping plates 6 that slide through a groove. On the opposite sides of the two clamping plates 6 on the same connecting ring 5, there are connecting blocks 7 welded to the opposite sides. The external parts of each connecting ring 5 are rotatably connected to the bidirectional screw 8. The connecting blocks 7 are threadedly connected to the corresponding bidirectional screw 8. A screw head 9 is welded to one side of each bidirectional screw 8.

[0024] like Figure 6 and Figure 8 As shown, it also includes a sealing ring 10 and an elastic sheet 13. Both the male connector 1 and the female connector 2 are bonded with sealing rings 10, which can effectively prevent water, dust and other foreign objects from entering the male connector 1 and the female connector 2. Five elastic sheets 13 distributed along the axial direction are bonded inside the connecting ring 3, which can help fix the cable.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, it also includes a locking block 11 and a retaining ring 12. Four locking blocks 11 distributed along the axial direction are welded to the lower outer end of the male connector 1. The locking blocks 11 are all made of engineering plastic and have a certain elasticity. A retaining ring 12 is welded to the outside of the female connector 2. The retaining ring 12 has four retaining grooves 1021 distributed along the axial direction. The locking blocks 11 are all inserted into the corresponding retaining grooves 1021.

[0026] Initially, the male connector 1, female connector 2, connecting ring 3, and collar 4 are all separated. When using this device, the operator first strips one end of the communication cable, then passes it through the collar 4 and connecting ring 3 corresponding to the male connector 1. Next, holding the male connector 1, the operator inserts the branch cables into the connecting rings 5. Then, holding a miniature screwdriver, the operator inserts it into the mating gap of the screw head 9 and rotates it. The rotation of the screw head 9 drives the bidirectional screw 8 to rotate synchronously, causing the two connecting blocks 7 on it to move axially along the bidirectional screw 8 and approach each other. The two clamping plates 6 move towards the cable synchronously until the inner wall of the clamping plate 6 is tightly fitted with the outer wall of the cable, at which point the rotation stops. The clamping plates 6 form a stable radial clamping force on the cable, firmly fixing the cable in the connecting ring 5. The cable can then be crimped and fixed to the conductive terminal inside the male connector 1. Next, the operator rotates the connecting ring 3 to gradually approach the male connector 1, so that the connecting ring 3 and the male connector 1 are tightly fitted by the threads. When both ends are completely... During the mating process, the sealing ring 10 is axially compressed, resulting in elastic deformation. This fills the tiny gap between the mating surfaces of the male connector 1 and the connecting ring 3, preventing external rainwater, moisture, or dust from seeping into the male connector 1 through the gap. After the connecting ring 3 is tightened, the collar 4 is rotated to completely wrap around the threaded connection of the connecting ring 3. The above operation is then repeated to press and fix one end of the other cable to the conductive terminal inside the female connector 2, and to fix the corresponding connecting ring 3 on the female connector 2. The collar 4 is then fixed on the connecting ring 3. After fixing, the male connector 1 is held and its bottom is aligned with the mating port of the female connector 2. Axial pressure is then applied to the male connector 1, causing the locking block 11 to overcome the resistance of the edge of the retaining ring 12 groove 1021 and elastically engage with the retaining ring 12. After the locking block 11 is fully engaged, the mating axes of the male connector 1 and the female connector 2 coincide, and radial displacement is restricted, thus completing the installation process of this device.

[0027] When disassembly is required, hold the male connector 1 and female connector 2 with both hands, insert a flathead screwdriver into the mating gap between the male connector 1 and female connector 2, and gently pry the locking block 11 to disengage it from the slot 1021. Then, pull the male connector 1 and female connector 2 in the opposite direction until they are completely separated. Next, hold the collar 4 and rotate it in the opposite direction to completely disengage it from the threaded area of ​​the connecting ring 3. Remove the collar 4 and store it properly. Then, rotate the connecting ring 3 in the opposite direction to disconnect it from the male connector 1 and female connector 2. Afterward, hold a miniature screwdriver and rotate it in the opposite direction, aligning it with the screw head 9, so that the two connecting blocks 7 move away from each other along the axial direction of the bidirectional screw 8. Simultaneously, the clamp 6 moves away from the cable until the inner wall of the clamp 6 is completely separated from the outer wall of the cable. Then, the cable can be pulled out from the connecting ring 5 of the male connector 1 and female connector 2 and passed through the connecting ring 3 and collar 4 in sequence. This completes the disassembly process. When it is needed again, repeat the above operation.
