Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and in particular relates to a novel longitudinal watertight optical fiber connector. Background Technology

[0002] Watertight fiber optic connectors are generally used in underwater optical transmission and sensing systems to connect optical cables and underwater equipment. They have broad application prospects in seabed observation networks, marine oil and gas exploration and development, marine ranching, and marine weapons.

[0003] As naval weapons and equipment become increasingly diverse, the demand for longitudinal watertight fiber optic connectors is growing. However, existing watertight fiber optic connectors are difficult to separate, making it difficult to clean the ceramic ferrule end face, and thus cannot meet the needs of new and diverse weapon selection. Utility Model Content

[0004] This invention addresses the problem in existing technologies where watertight fiber optic connectors are difficult to separate, making it difficult to clean the ceramic ferrule end face. The following technical solution is proposed:

[0005] A novel longitudinal watertight fiber optic connector includes: a connector plug and a connector socket. The connector plug includes a plug housing and a screw sleeve rotatably fitted onto the outer surface of the plug housing. A stepped block is provided on the outer surface of the plug housing. A retaining ring is provided between the stepped block and the screw sleeve. A plug base with a pin assembly is provided inside the plug housing. A retaining ring is provided between one end of the plug base and the plug housing. A sleeve assembly is provided at the other end of the plug base.

[0006] The stepped blocks on the outer surface of the plug housing prevent the screw sleeve from coming off during the mating process of the connector plug and connector socket. In addition, the stepped blocks can swing back and forth when used with the retaining ring, making the connector mating and disassembly operations smoother. This solves the problem of watertight connectors being difficult to disassemble and facilitates cleaning of the ceramic ferrule end face.

[0007] As a preferred embodiment of the above technical solution, the sleeve assembly includes a sleeve upper cover, a sleeve lower cover, and a plurality of ceramic sleeves. The ceramic sleeves are movably inserted between the sleeve upper cover and the sleeve lower cover, and a metal protective tube is provided on the outer surface of the ceramic sleeves.

[0008] The ceramic sleeve is housed within the movable sleeve formed by the upper and lower sleeve covers, and the sleeve assembly can be removed from the connector plug for easy cleaning of the contact end face of the connector plug. At the same time, the ceramic sleeve is reinforced with a metal sheath to ensure that it will not be damaged by external impacts during connector mating.

[0009] As a preferred embodiment of the above technical solution, a baffle is provided at one end of the lower sleeve cover, and a hexagonal screw is provided at one end of the baffle to be inserted into the plug base.

[0010] The sleeve assembly can be easily installed using hexagonal screws, and the sleeve assembly can also be limited by the hexagonal screws to prevent the sleeve assembly from moving and affecting the docking of the pin assembly.

[0011] As a preferred embodiment of the above technical solution, the connector socket includes a socket housing and a socket base with pin fittings, and a sealing ring is provided between the socket base and the socket housing.

[0012] The sealing ring between the socket base and the socket housing provides multiple layers of sealing to the socket housing, thereby ensuring longitudinal watertightness when the connector panel is installed.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The stepped blocks on the outer surface of the plug housing can prevent the screw sleeve from coming out during the mating process of the connector plug and connector socket. In addition, the stepped blocks can swing back and forth when used with the retaining ring, making the connector mating and disassembly operations smoother. This solves the problem of watertight connectors being difficult to disassemble and makes it easier to clean the ceramic ferrule end face.

[0015] 2. The ceramic sleeve is set inside the movable sleeve formed by the upper sleeve cover and the lower sleeve cover, and the sleeve assembly can be removed from the connector plug to facilitate cleaning of the contact end face of the connector plug. At the same time, the ceramic sleeve is strengthened by adding a metal sheath to the outside, ensuring that the ceramic sleeve will not be damaged by external impact during connector mating.

The connector plug includes a plug housing 11 and a screw sleeve 12 rotatably fitted onto the outer surface of the plug housing 11. A stepped block 111 is provided on the outer surface of the plug housing 11. A retaining ring 13 is provided between the stepped block 111 and the screw sleeve 12. A plug base 14 with a pin assembly is provided inside the plug housing 11. A retaining ring 15 is provided between one end of the plug base 14 and the plug housing 11. A sleeve assembly 16 is provided at the other end of the plug base 14.

[0024] The stepped block 111 on the outer surface of the plug housing 11 can prevent the screw sleeve 12 from coming off during the mating process of the connector plug and connector socket. Furthermore, the stepped block 111 can swing back and forth when used in conjunction with the retaining ring 15, making the connector mating and disassembly operations smoother. This solves the problem of watertight connectors being difficult to disassemble and facilitates cleaning of the ceramic ferrule end face.

[0025] Figures 1-3 In the process, the sleeve assembly 16 includes a sleeve upper cover 161, a sleeve lower cover 162 and a plurality of ceramic sleeves 163. The ceramic sleeves 163 are movably inserted between the sleeve upper cover 161 and the sleeve lower cover 162, and a metal protective tube 164 is provided on the outer surface of the ceramic sleeves 163.

[0026] The ceramic sleeve 163 is disposed inside the movable sleeve formed by the upper sleeve cover 161 and the lower sleeve cover 162, and the sleeve assembly 16 can be removed from the connector plug to facilitate cleaning of the contact end face of the connector plug. At the same time, the ceramic sleeve is strengthened by adding a metal sleeve 164 to the outside, ensuring that the ceramic sleeve 163 will not be damaged by external impact during connector mating.

[0027] Figure 3In the process, a baffle 165 is provided at one end of the lower sleeve cover 162, and a hexagonal screw 166 is provided at one end of the baffle 165 for insertion into the plug base 14.

[0028] The sleeve assembly 16 can be easily installed using the hexagonal screw 166, and the sleeve assembly 16 can be limited by the hexagonal screw 166 to prevent the sleeve assembly 16 from moving and affecting the docking of the pin assembly.

[0029] Figure 1 and Figure 4 In the connector socket, there are a socket housing 21 and a socket base 22 with pin assembly. A sealing ring 23 is provided between the socket base 22 and the socket housing 21. The sealing ring 23 is a type of panel contact sealing ring 23.

[0030] The sealing ring 23 between the socket base 22 and the socket housing 21 can provide multi-layer sealing for the socket housing 21, thereby ensuring longitudinal watertightness when the connector panel is installed.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
