[0002] During the installation and maintenance of optical cables, ensuring their waterproof sealing is crucial. Optical cables are exposed to moisture, humidity, and dust in outdoor or underground environments. If the seal is not adequate, moisture can penetrate the cable, causing serious problems such as signal attenuation and communication interruptions. Therefore, waterproof optical cable sealing splitters have gradually emerged on the market. These splitters typically utilize sealing materials and fastening structures to prevent moisture intrusion, ensuring stable operation of the optical cable in harsh environments.

[0003] However, while existing fiber optic cable waterproof plugging splitters meet basic sealing requirements, they suffer from significant installation deficiencies. Many splitters use threaded connections to secure the upper and lower shells, ensuring a tight seal. However, this connection method is cumbersome to install and remove, lacking the convenience of quick assembly and disassembly. This makes installation particularly inefficient in scenarios requiring frequent maintenance and inspection, increasing construction time and labor costs. Utility Model Content

[0028] Furthermore, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example

[0030] Reference Figures 1 to 5 This embodiment provides a waterproof fiber optic cable splitter. The splitter primarily comprises an optical cable 100 and a splitter 200. The optical cable 100 consists of a cable core 101 encased in a protective sheath, ensuring signal transmission. The protective sheath effectively prevents damage to the optical cable from environmental factors such as moisture, humidity, and dust, ensuring the cable's protective performance.

[0031] Specifically, the splitter 200 consists of a base 201 and a sealing cover 202, and is designed to provide a waterproof seal for the optical cable. Slots 201a are symmetrically arranged on the front and rear sides of the top of the base 201. These slots 201a are used to cooperate with the card plates 203 symmetrically installed at the bottom of the sealing cover 202, allowing the sealing cover to be securely mounted on the base, thereby achieving rapid snap-on and sealing functions, improving the waterproof effect and fixing strength. Movable slots 201b are also symmetrically arranged on the front and rear sides of the bottom of the base 201. A cavity 201c is provided between the two movable slots 201b to provide space for the operation of the internal positioning assembly 204 and the drive assembly 205, and to ensure smoother installation and removal of the splitter.

[0032] Furthermore, the positioning assembly 204 is a key part in the branching device for achieving stable fixation and rapid disassembly of the sealing cover. The positioning assembly 204 includes a slide 204a slidably connected to the inside of the movable groove 201b, and the slide 204a can slide freely in the movable groove 201b, thereby achieving limit adjustment of the sealing cover. One end of the slide 204a is fixedly connected to a connecting rod 204b, and the connecting rod 204b passes through the inner wall of the base 201 and extends to the outside. The outer part is fixedly connected to a movable plate 204c, and the movable plate is used to transmit driving force and control the position of the latch. The top inner side of the movable plate 204c is fixedly connected to a latch 204d, and the latch is designed to cooperate with the positioning groove 203a of the card plate 203 to achieve limit and fixation of the sealing cover. When the latch 204d is inserted into the positioning groove 203a, the sealing cover can be firmly fixed on the base, thereby ensuring the effect of waterproof sealing.

[0033] Furthermore, the drive assembly 205 realizes the quick assembly and disassembly operation of the sealing cover by interlocking with the positioning assembly. The drive assembly 205 includes a knob 205a that is rotatably connected to the outside of the right side of the base 201. The knob 205a is used to manually drive the entire positioning process. The left end of the knob is fixedly connected to a rotating rod 205b. The rotating rod 205b passes through the right side wall of the base 201 and extends into the cavity 201c. It is fixedly connected to the active conical teeth 205c. The active conical teeth 205c are designed to transmit the rotational force of the knob to the driven conical teeth 205d. The driven conical teeth 205d are respectively located on the front and rear sides of the active conical teeth. By engaging with the active conical teeth, power transmission and conversion are achieved. The opposite sides of the two driven conical teeth 205d are fixedly connected to a threaded rod 205e. The function of the threaded rod 205e is to convert rotational motion into linear motion, which is used to drive the horizontal movement of the slide 204a. The other ends of the two threaded rods 205e respectively pass through the cavity 201c and extend into the two movable grooves 201b, ensuring that the slide plate 204a can slide smoothly in the movable grooves 201b.

[0034] The two slides 204a are respectively threaded onto the outer surfaces of the two threaded rods 205e. By turning the knob 205a, the threaded rods 205e rotate, and the slides 204a slide along the movable groove 201b, thereby controlling the separation or insertion of the latch 204d into the positioning groove 203a. This design significantly reduces tedious manual operations, making the installation and removal of the sealing cover and the base faster and more efficient, and is particularly suitable for optical cable installation scenarios that require frequent maintenance. At the same time, the structural design of the cavity 201c within the base 201 allows the various parts of the positioning assembly and the drive assembly to be arranged compactly, improving the operational convenience and sealing reliability of the overall structure of the splitter.

[0035] The working principle of this device is:

[0036] When the staff turns the knob 205a, the knob 205a drives the rotating rod 205b fixed to its left end to rotate, and the rotating rod 205b transmits the rotational motion to the active conical tooth 205c in the cavity 201c. The active conical tooth 205c meshes with the two driven conical teeth 205d. The rotation of the active conical tooth 205c drives the driven conical teeth 205d to rotate synchronously. Since the driven conical teeth 205d are respectively located on the front and rear sides of the active conical tooth 205c, they rotate in opposite directions relative to each other. The rotation causes the threaded rod 205e fixedly connected to the opposite side to also start to rotate. The rotation of the threaded rod 205e further drives the slide 204a to move horizontally in the moving groove 201b. The moving direction of the slide 204a depends on the rotation direction of the threaded rod 205e. When the knob 205a rotates clockwise, the threaded rod 205e drives the two slides 204a to move in opposite directions, thereby driving the moving plate 204c away from the base 201 through the connecting rod 204b. As the moving plate 204c moves, the pin 204d is also driven to detach from the card plate. 203, the positioning groove 203a of the sealing cover 202 is released from the base 201. At this time, the staff can remove the sealing cover 202 from the top of the base 201 to conveniently remove and maintain the optical cable 100. On the contrary, when the staff rotates the knob 205a in the opposite direction, the threaded rod 205e drives the slide 204a to move in the opposite direction. The slide 204a drives the moving plate 204c to move toward the base 201 through the connecting rod 204b, and the latch 204d is reinserted into the positioning groove 203a of the card plate 203. The sealing cover 202 is firmly fixed on the base 201; when installing the optical cable, the staff lays the end of the optical cable 100 with the protective cover in the protective groove 206, and then lays the multiple cable cores 101 without the protective covers in multiple branch grooves 207 respectively, and finally covers the sealing cover 202, rotates the knob 205a in the opposite direction, so that the threaded rod 205e drives the slide 204a to move, so that the pin 204d is reinserted into the positioning groove 203a, and the clamping plate 203 is fixed in the clamping groove 201a to complete the installation and sealing operation of the optical cable.

[0037] Through this design, staff can easily separate and fix the sealing cover 202 from the base 201 quickly, which greatly improves the operating efficiency of the optical cable waterproof sealing device, reduces the complexity of installation and maintenance, and ensures the safe sealing effect of the optical cable. It is suitable for various optical cable laying environments that require efficient waterproofing and easy maintenance.
