It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

Embodiment as shown in fig. 1 to 6, an outdoor waterproof optical fiber direct melting box comprises an outer box 1 and a pair of optical fiber wires 2 located at two ends of the outer box 1, wherein the two optical fiber wires 2 are installed on a clamping seat 4 inside the outer box 1 through end welding. Outer box 1's outside both ends all are equipped with external screw thread 101, still install locking lid 3 respectively on being located outer box 1 both ends outside optic fibre line 2 simultaneously, and locking lid 3 can move along optic fibre line 2 through centre bore 302, and the inner wall of locking lid 3 is equipped with internal thread 301. Each optical fiber 2 is also provided with a rubber sealing ring 5 in a sliding way, and the sealing ring 5 is positioned between the locking cover 3 and the end part of the outer box 1. When directly melting the box and need locking, only need to lock the internal thread 301 of lid 3 and the external screw thread 101 at outer box 1 both ends and close the locking soon, at the in-process that locking lid 3 closed soon, can drive sealing washer 5 through the inside terminal surface of locking lid 3 and carry out axial displacement along the tip inner wall of outer box 1 to closely laminate with outer box 1 both ends inner wall, play waterproof seal's effect.

Specifically, as shown in fig. 3 and 4, the sealing ring 5 is in a truncated cone shape, a fitting hole 501 is formed in the center of the sealing ring 5, and the sealing ring 5 is slidably fitted with the optical fiber 2 through the fitting hole 501. Meanwhile, the seal ring 5 is provided with a first communication port 502 in the radial direction, and the first communication port 502 communicates with the fitting hole 501. When the grommet 5 is attached, the grommet 5 may be inserted into the optical fiber 2 along the end of the optical fiber 2 that is not welded through the fitting hole 501 for the first attachment, or the optical fiber 2 may be directly pushed into the grommet 5 through the first communication hole 502 on the radial side wall. When the equipment maintenance is carried out, the sealing ring 5 can be directly detached from the optical fiber cable 2 through the first communication port 502 for replacement, and the detaching and installing process is very simple and quick.

Due to the soft rubber material of the sealing ring 5, when the first communicating opening 502 is opened, the opened width can be smaller than the diameter of the optical fiber 2, so that when the sealing ring 5 is installed, the optical fiber 2 can be installed inside the sealing ring 5 only by elastic deformation of the first communicating opening 502. Meanwhile, when the sealing ring 5 is tightly attached and sealed with the end of the outer box 1, the first communication port 502 is sealed by the deformation of the sealing ring 5 in the circumferential direction only through small axial displacement, so that the sealing performance of the sealing ring 5 is improved.

In order to prevent the inner end face of the locking cover 3 from wearing the sealing ring 5 due to rotation when the locking cover is screwed, as shown in fig. 3 and 4, a circular top block 6 can be installed between the locking cover 3 and the sealing ring 5, the top block 6 is made of hard plastic which is relatively wear-resistant, a through hole 601 is formed in the center of the top block 6, and the top block 6 is matched with the optical fiber 2 through the through hole 601. Meanwhile, a second communication port 602 is formed in the radial direction of the top block 6, the second communication port 602 is communicated with the through hole 601, the width of the second communication port 602 can be larger than the diameter of the optical fiber 2, and the width of the second communication port 602 can also be slightly smaller than the diameter of the optical fiber 2, and the second communication port can be adjusted conveniently according to actual production. The top block 6 is installed and replaced in the same or similar way as the sealing ring 5. When the locking cover 3 is locked, the locking cover 3 indirectly contacts and extrudes the sealing ring 5 through the top block 6, so that the abrasion caused by the contact of the locking cover 3 and the sealing ring 5 is avoided.

Simultaneously, for the convenience of the cooperation of kicking block 6 and locking lid 3, generally with the internal diameter that is less than locking lid 3 of the diameter setting of kicking block 6, but because the problem of preparation precision occasionally, the diameter of kicking block 6 can be about the same with the internal diameter of locking lid 3 occasionally to can drive kicking block 6 rotatory simultaneously when locking lid 3 is rotatory, this will cause 5 ends of sealing washer to produce wearing and tearing. Therefore, the limiting groove 503 may be provided on the large end surface of the sealing ring 5, and the limiting block 603 may be provided on the end surface of the top block 6 contacting the sealing ring 5, where the number of the limiting groove 503 and the number of the limiting block 603 are equal and may be provided in plural, for example, as shown in fig. 3 and 4, the number of the limiting groove 503 and the limiting block 603 is three. Then through the cooperation of spacing groove 503 and stopper 603, link into an integrated entity ejector block 6 and sealing washer 5, can prevent that ejector block 6 from covering 3 synchronous revolution when closing soon at the locking.

Specifically, as shown in fig. 2, 5 and 6, the optical fiber lines 2 are fusion spliced by end-mounted jumper tabs 201, and the specific fusion splicing method belongs to the conventional technology in the field. In order to prevent the welded jumper connector 201 from loosening in the clamping seat 4, the clamping block 202 can be arranged at the end of the jumper connector 201, the clamping groove 401 is arranged at the corresponding mounting position in the clamping seat 4, and then when the welded jumper connector 201 is mounted, the jumper connector 201 can be guaranteed not to deviate through the matching of the clamping block 202 and the clamping groove 401.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and these changes and modifications are intended to be within the scope of the application as claimed. The scope of protection claimed by this application is defined by the following claims and their equivalents.
