Description

Technical Field

[0001] This utility model relates to the field of optoelectronic signal transmission technology, and specifically to a connector for optoelectronic cables. Background Technology

[0002] Fiber optic communication is a type of wired communication that uses light and optical fibers to transmit information. Light, after being modulated, can carry information. Fiber optic communication has advantages such as large transmission capacity and high security, and has become the most important wired communication method today. To ensure stable optical signal data transmission, splicing is required during the installation / layout of fiber optic cable bundles.

[0003] Chinese utility model patent application number 202220811480.X discloses a wire harness splicing module for optical fiber data transmission, including a lower clamp. The lower clamp has a recessed portion, and a splicing component is disposed within the recessed portion. The splicing component rotates and moves up and down along the inner wall of the recessed portion. The lower clamp has a lower wiring groove, and a through hole communicating with the recessed portion is provided in the lower wiring groove. The splicing component includes a screw connector that is screwed to the inner wall of the recessed portion. A splicing rod is rotatably connected to the bottom of the screw connector. The outer wall of the screw connector is threaded to the inner wall of the recessed portion. By rotating the screw connector, it can be moved within the recessed portion, allowing the splicing rod to move in or out of the recessed portion. This ensures that the wire harness wound on the splicing rod can be hidden and fixed, and also facilitates the disassembly of the wire harness splice, improving the flexibility of the wire harness splicing operation. This wire harness splicing module uses a wiring channel to limit and fix the positions of the wire harnesses that need to be spliced ​​on both sides. With the use of a rotatable and liftable splicing component, the splice of the two wire harnesses can be pressed and reinforced after splicing, ensuring that the splice of the two wire harnesses can remain hidden and stable, preventing the splice from being exposed and loosening, and effectively improving the splicing effect of the wire harnesses.

[0004] The aforementioned wire harness splicing module requires unlocking the splicing components to open the upper and lower clamps and expose the wiring slots. The connectors of the two wire harnesses are then placed in the slots, and the upper and lower clamps are closed to clamp and compress the connectors. Finally, the splicing components lock the upper and lower clamps together. This entire process is complex, involves many steps, and is time-consuming. Furthermore, the connectors of the two wire harnesses cannot be quickly and accurately aligned, which affects optical signal transmission. In addition, this wire harness splicing module cannot connect power cables, failing to meet usage requirements.

The front end of the second fiber optic ceramic ferrule assembly 24 is exposed outside the front end of the ferrule rear cover 22 and passes through and is exposed in the first mating hole 231. The front end of the male connector 25 passes through and is exposed in the second mating hole 232. The second fiber optic cable 240 connected to the second fiber optic ceramic ferrule assembly 24 and the second wire 250 connected to the male connector 25 both extend outside the insulating cylinder 21. The male connector 2 and the female connector 1 are connected. After mating, the mating cylinder 112 is inserted into the first mating hole 231, and the end of the second fiber ceramic ferrule assembly 24 is also embedded in the mating groove 1120 of the mating cylinder 112, corresponding to the first fiber ceramic ferrule assembly 12, ensuring the stability and alignment of the mating, making the optical signal transmission more stable and of higher quality. Furthermore, the ends of the first fiber optic cable 120 and the second fiber optic cable 240 are located on the same straight line and are close to or in contact with each other, and the male terminal 25 is in contact with and connected to the female terminal 13. In other words, when it is necessary to connect the first optical fiber 120 and the second optical fiber 240, this utility model can be achieved simply by inserting the male connector 2 into the female connector 1. The operation is extremely simple, with very few steps, and is quick and inexpensive. After the male connector 2 and the female connector 1 are inserted, the mating cylinder 112 in the female connector 1 is inserted into the first mating hole 231 in the male connector 2. The end of the second optical fiber ceramic ferrule assembly 24 is also embedded in the mating groove 1120 of the mating cylinder 112 and corresponds to the first optical fiber ceramic ferrule assembly 12, ensuring the stability and alignment of the insertion, making the optical signal transmission more stable and of higher quality. The ends of the first optical fiber 120 and the second optical fiber 240 are on the same straight line and close to or in contact with each other, achieving fast and accurate connection, which ensures the subsequent transmission of optical signals. The male connector terminal 25 contacts and conducts with the female connector terminal 13, realizing the connection of the first wire 130 and the second wire 250, which can meet different usage requirements.

[0031] For ease of use, the following design was also implemented:

[0032] The lower end of the plastic shell 11 is provided with a detachable connecting buckle 14, and the lower end of the connecting buckle 14 is provided with several elastic buckle arms 141. The upper periphery of the elastic buckle arms 141 is provided with a locking groove 142. In use, the female connector 1 can be locked into the slot at a certain position by the connecting buckle 14, ensuring a more stable connection between the female connector 1 and the male connector 2, and facilitating wiring. Specifically, when the connecting buckle 14 is inserted into the slot, the elastic buckle arms 141 are locked and fixed to the inner wall of the slot to form a stable assembly.

[0033] Furthermore, in some other embodiments, the lower end of the connecting buckle 14 is also provided with an inclined tensioning spring 143, which is distributed on the outside of the elastic buckle arm 141. When the connecting buckle 14 is snapped into a slot at a certain position, the tensioning spring 143 elastically presses against the outer edge of the slot opening to form elastic support, thereby ensuring the stability of the buckle assembly.

[0034] The assembly structure of the connecting buckle 14 and the plastic shell 11 is as follows: the lower end of the plastic shell 11 is provided with a U-shaped limiting groove 113, and the two sides of the connecting buckle 14 are provided with limiting rails 144. The limiting rails 144 are slotted in the middle to form a spring arm 145. The limiting rails 144 are embedded in the limiting groove 113, and the spring arm 145 is engaged and positioned with the inner wall of the limiting groove 113 to form a stable assembly. It is not easy for it to accidentally detach. When the connecting buckle 14 is not needed, it can be detached from the plastic shell 11.

[0035] In addition, a first buckle body 1130 is provided in the limiting slot 113. The connecting buckle 14 is provided with a slot body. The first buckle body 1130 is engaged and positioned with the slot body, making the assembly structure of the connecting buckle 14 and the plastic shell 11 more stable.

[0036] The plastic shell 11 has a mounting groove 114 on its rear side. The first optical fiber ceramic ferrule assembly 12 is installed in the mounting groove 114 by a fixing seat 15. The fixing seat 15 and the mounting groove 114 are sealed by injecting glue to form a sealing block 16, which also seals and fixes the first optical fiber 120 and the first electrical wire 130. This not only greatly enhances the sealing and waterproof performance, but also improves the stability of the assembly structure.

[0037] The first fiber optic ceramic ferrule assembly 12 includes: a first ceramic ferrule 121, a ceramic sleeve 122 fitted onto the front end of the first ceramic ferrule 121, a first ceramic tail shank 123 disposed at the rear end of the first ceramic ferrule 121, and a first riveting cylinder 124 riveting and fixing the exterior of the first ceramic tail shank 123 and the exterior of the first optical fiber 120. The entire first fiber optic ceramic ferrule assembly 12 has a simple structure, and the first ceramic tail shank 123 is fixedly inserted into the fixing base 15. The end of the ceramic ferrule 121 passes through the fixing base 15 and extends out of the front end of the fixing base 15, which facilitates the installation of the entire first optical fiber ceramic ferrule assembly 12 into the mounting groove 114 on the rear side of the plastic shell 11; the ceramic sleeve 122 passes through and is fixed in the docking groove 1120 of the docking cylinder 112; the first optical fiber 120 passes through the first ceramic tail shank 123 and the first ceramic ferrule 121; the sealing block 16 also wraps around the first ceramic tail shank 123 and the first riveting cylinder 124 to improve the stability of the assembly structure.

[0038] The following is a detailed description of the specific structure of the second optical fiber ceramic ferrule assembly 24.

[0039] The second fiber optic ceramic ferrule assembly 24 includes: a second ceramic ferrule 241, a second ceramic tail shank 242 disposed at the rear end of the second ceramic ferrule 241, a flexible tube 243 sleeved around the rear end of the second ceramic tail shank 242, a fixing tube 244 sleeved around the second ceramic tail shank 242 and the flexible tube 243, a second riveting cylinder 245 riveting the fixing tube 244 and the second fiber optic cable 240 together, and a spring 246 disposed between the second ceramic tail shank 242 and the fixing tube 244. The fixing tube 244 is fixedly inserted into the ferrule rear cover 22, enabling a stable assembly of the entire second fiber optic ceramic ferrule assembly 24 with the ferrule rear cover 22. The second riveting cylinder 245 rivets the fixing tube 244 and the second fiber optic cable 240 together, thus forming a stable connection between the second fiber optic ceramic ferrule assembly 244 and the second fiber optic cable 240.

[0040] The second optical fiber 240 passes through the second ceramic tail shank 242, the second ceramic ferrule 241, the flexible tube 243, and the fixing tube 244, and extends out of the insulating tube 21.

[0041] The ferrule 23 has a sliding groove 233 on its rear side. An inner convex flange 234 is provided between the sliding groove 233 and the first mating hole 231. The inner convex flange 234 has a first inclined pressing surface 2340 with an inclination angle of 50°-70° on the side near the sliding groove 233. The inclination angle of the first inclined pressing surface 2340 is preferably 60°. Correspondingly, the front end of the second ceramic tail 242 has a second inclined pressing surface 2420 adapted to the first inclined pressing surface 2340. The inclination angle of the second inclined pressing surface 2420 is preferably 60°. The size of the second inclined pressing surface 2420 is smaller than that of the first inclined pressing surface 2340. The second inclined pressing surface 2420 of the second ceramic tail 242 contacts the first inclined pressing surface 2340 under the elastic force of the spring 246, and the second inclined pressing surface 2420 and the first inclined pressing surface 2340 can move relative to each other in the radial direction. In other words, the second inclined pressing surface 2420 of the second ceramic tail shank 242 contacts the first inclined pressing surface 2340 under the elastic force of the spring 246, and the second inclined pressing surface 2420 and the first inclined pressing surface 2340 can move relative to each other in the radial direction. This allows the second optical fiber ceramic ferrule assembly 24 to be finely adjusted relative to the first mating hole 231, providing tolerance. As a result, when the second optical fiber ceramic ferrule assembly 24 is inserted into the mating groove 1120 of the mating cylinder 112 at the front end, no damage will occur, ensuring product quality.

[0042] The upper end of the insert cover 22 is provided with a first limiting groove 221. The second wire 250 connected to the rear end of the male connector 25 is pressed into and fixed in the first limiting groove 221, which ensures the stability of the assembly structure.

[0043] A sealing plug 211 is inserted into the rear end of the insulating cylinder 21, and an end cap 212 is fixedly connected to the rear end of the insulating cylinder 21. The end cap 212 confines the sealing plug 211 to the rear end of the insulating cylinder 21, thereby improving the sealing and waterproof performance. The sealing plug 211 has a first through hole 201 and a second through hole 202. The end cap 212 has a third through hole 203 and a fourth through hole 204 corresponding to the first and second through holes 201 and 202, respectively. The second wire 250 and the second optical fiber 240 are respectively inserted and fixed in the first and second through holes 201 and 202, forming an interference fit assembly, thus achieving a sealed assembly with excellent waterproof performance. The second wire 250 and the second optical fiber 240 extend out of the end cap 212 through the third and fourth through holes 203 and 204. The sealing plug 211 is preferably made of rubber.

[0044] The male connector 2 also includes a plastic outer shell 27, which is fitted and fixed to the outside of the insulating cylinder 21. It forms an interlocking space 270 for fitting with the front end of the plastic shell 11. A second sealing ring 213 is provided around the insulating cylinder 21. The second sealing ring 213 is located in the interlocking space 270 and is used to form a sealed assembly with the female connector 1 to improve the waterproof performance of the product.

[0045] The plastic outer shell 27 and the insulating cylinder 21 are fixed together by a snap-fit ​​structure.

[0046] The plastic outer shell 27 is provided with an elastic locking plate 271, and the front end of the elastic locking plate 271 is provided with a locking slot 272; the front end of the plastic shell 13 is provided with a buckle 110. After the plastic shell 11 and the plastic outer shell 27 are inserted into each other, the buckle 110 and the locking slot 272 lock and fix them, so that the male head 2 and the female connector 1 form a stable assembly and are not easy to accidentally detach.

[0047] In summary, when it is necessary to connect the first optical fiber 120 and the second optical fiber 240, this utility model can be achieved simply by inserting the male connector 2 into the female connector 1. The operation is extremely simple, involves very few steps, is quick, and inexpensive. After the male connector 2 and the female connector 1 are inserted, the mating cylinder 112 in the female connector 1 is inserted into the first mating hole 231 in the male connector 2. Furthermore, the end of the second optical fiber ceramic ferrule assembly 24 is also embedded in the mating groove 1120 of the mating cylinder 112, corresponding to the first optical fiber ceramic ferrule assembly 12, ensuring the stability and alignment of the connection, making the optical signal transmission more stable and of higher quality. The ends of the first optical fiber 120 and the second optical fiber 240 are located on the same straight line and are close to or in contact with each other, achieving rapid and precise connection, ensuring subsequent optical signal transmission. The male connector terminal 25 contacts and conducts with the female connector terminal 13, realizing the connection of the first wire 130 and the second wire 250, which can meet different usage requirements.
