Description

Technical Field

[0002] With the rapid development of network transmission technology, optical fiber has been widely used in various industries. Optical fiber is a fiber made of glass or plastic, mainly used as a light transmission tool. By connecting optical fiber to terminal equipment, high-speed communication can be achieved.

[0046] Specifically, the connector body 100 is the base of the optoelectronic composite connector, and the outer wall of the connector body 100 is provided with a first groove 130, and a first sealing ring 140 is installed in the first groove 130, and a part of the first sealing ring 140 protrudes from the first groove 130. When the optoelectronic composite connector is used, it is installed inside the cylinder, and the first sealing ring 140 on the connector body 100 is squeezed by the inner wall of the cylinder to achieve the effect of blocking the space on both sides of the optoelectronic composite connector in the sealed cylinder.

[0047] The connector body 100 is provided with an optical fiber jack 110 and an electrode jack 120, and both the optical fiber jack 110 and the electrode jack 120 penetrate the connector body 100 along the thickness direction of the connector body 100. The optical fiber connector 200 is sealed and installed in the optical fiber jack 110, one end of the optical fiber connector 200 extends out of one end of the optical fiber jack 110, and the other end of the optical fiber connector 200 extends out of the other end of the optical fiber jack 110. The optical fiber connector 200 can be fixed and locked in the optical fiber jack 110 of the connector body 100 by threading to achieve a detachable connection between the optical fiber connector 200 and the connector body 100, or a non-detachable connection between the optical fiber connector 200 and the connector body 100 can be achieved by welding or other methods. The optical fiber connector 200 can be sealed with the optical fiber jack 110 by sealing glue or a sealing ring. ; Exemplarily, the fiber optic connector 200 includes a second sealing ring 230, and the outer side wall of the connector body 210 is provided with a second groove 211, the second sealing ring 230 is installed in the second groove 211 and abuts against the inner side wall of the fiber optic jack 110, and the second sealing ring 230 is squeezed by the inner wall of the fiber optic jack 110 to achieve sealing performance, thereby realizing a sealed connection between the fiber optic connector 200 and the fiber optic jack 110; the fiber optic connector 200 and the fiber optic jack 110 are sealed by the sealing ring, which can facilitate the disassembly of the fiber optic connector 200 and the connector body 100, thereby facilitating the maintenance and replacement of the fiber optic connector 200.

[0048] The optical fiber connector 200 includes a connector body 210 and an optical fiber 220. The optical fiber 220 is inserted into the connector body 210. The optical fiber 220 can be sealed and fixed in the optical fiber installation hole of the connector body 210 by sealing solder or glue. The sealing solder can ensure the sealing and fixing of the optical fiber 220 and the connector body 210, and has the functions of high temperature resistance and pressure resistance. The two ends of the optical fiber 220 can extend out of the two ends of the connector body 210, or the two ends of the optical fiber 220 are respectively flush with the two ends of the connector body 210. The two ends of the optical fiber 220 and / or the connector body 210 extend out of the two ends of the optical fiber jack 110, so as to connect one optical cable through one end of the optical fiber connector 200 and connect another optical cable through the other end of the optical fiber connector 200, so as to realize the connection of the two optical cables.

[0049] The electrode 300 can be sealed in the electrode socket 120 by sealing solder or glue. The sealing solder is melted at high temperature and then cooled, which can effectively seal the electrode socket 120 of the joint body 100, and has high temperature resistance and pressure resistance. The two ends of the electrode 300 extend out of the two ends of the electrode socket 120 respectively, and the connection of two cables can be achieved through the electrode 300. The present application uses the electrode 300 to achieve the connection of two cables, which can reduce the size of the joint.

[0050] In the present application, a fiber optic jack 110 and an electrode jack 120 are provided on the connector body 100, and a fiber optic connector 200 is provided in the fiber optic jack 110, and an electrode 300 is provided in the electrode jack 120, so that different optical cables and different electrical cables can be connected at the same time, which simplifies the connector structure. Compared with the connection using optical connectors and electrical connectors separately, the occupied volume of the connector is reduced; the fiber optic connector 200 directly adopts a sealed buried section of optical fiber 220 to replace the existing complex optical path structure, which not only simplifies the structure and reduces the size of the optical connector, but also effectively reduces the number of optical reflection surfaces, reduces reflection loss, and improves light transmission efficiency; in addition, the existing sealing ring plus commercial electrical connector structure is replaced by directly sealing and burying one end electrode 300 on the connector body 100, which effectively reduces the diameter size of the electrical connector.

[0051] In a specific embodiment, Figure 3 As shown, the fiber optic connector 200 also includes a first fiber optic pin 240 and a second fiber optic pin 250. The first fiber optic pin 240 and the second fiber optic pin 250 can be made of metal materials, such as stainless steel sleeves. The first fiber optic pin 240 is provided with a first through hole 241, and the second fiber optic pin 250 is provided with a second through hole 251. One end of the first fiber optic pin 240 is connected to one end of the connector body 210, and one end of the optical fiber 220 extends into the first through hole 241 and extends to the other end of the first fiber optic pin 240. One end of the second fiber optic pin 250 is connected to the other end of the connector body 210, and the other end of the optical fiber 220 extends into the second through hole 251 and extends to the other end of the second fiber optic pin 250.

[0052] When the optical fiber connector 200 is used to connect two optical cables (respectively, a first optical cable and a second optical cable), the first optical fiber pin 240 is docked with the adapter of the first optical cable, and the second optical fiber pin 250 is docked with the adapter of the second optical cable, so that the optical fiber 220 at the end of the first optical fiber pin 240 is aligned and connected with the optical fiber in the first optical cable, and the optical fiber 220 at the end of the second optical fiber pin 250 is aligned and connected with the optical fiber in the second optical cable, so as to achieve the connection between the optical fiber in the first optical cable and the optical fiber in the second optical cable. In this embodiment, optical fiber pins are respectively arranged at both ends of the connector body 210, and the optical fiber pins can be connected with the adapter on the optical cable to achieve the connection between different optical cables, so that the connection process is simple and convenient, and the optical fibers are easy to align. Compared with the existing optical joints that are difficult to adjust and align due to the processing accuracy of the collimator, this embodiment can reduce the difficulty of alignment and reduce the reflection loss of light.

It can be understood that the first optical fiber pin 240 can also be fixed in the first installation groove by welding, gluing, etc., and the second optical fiber pin 250 can also be fixed in the second installation groove by welding, gluing, etc.

[0055] Further, such as Figure 3 As shown, the optical fiber connector 200 further includes a first interface nut 260 and a second interface nut 270. The first interface nut 260 is sleeved on the outside of the first optical fiber pin 240, and the second interface nut 270 is sleeved on the outside of the second optical fiber pin 250. When the first optical fiber pin 240 is connected to the adapter of the first optical cable, the first interface nut 260 can be threadedly connected to the adapter of the first optical cable to achieve a fixed connection between the first optical fiber pin 240 and the adapter of the first optical cable. When the second optical fiber pin 250 is connected to the adapter of the second optical cable, the second interface nut 270 can be threadedly connected to the adapter of the second optical cable to achieve a fixed connection between the second optical fiber pin 250 and the adapter of the second optical cable, so as to connect the optical fiber connector 200 to the first optical cable and the second optical cable together. In this embodiment, the first fiber optic pin 240, the first interface nut 260, and the optical fiber 220 in the first fiber optic pin 240 can constitute a standard fiber optic interface. When the first interface nut 260 is fixedly connected to the adapter of the first optical cable, it can ensure that the optical fiber 220 at the end of the first fiber optic pin 240 is exactly aligned and connected with the optical fiber in the first optical cable; similarly, the second fiber optic pin 250, the second interface nut 270, and the optical fiber 220 in the second fiber optic pin 250 also constitute a standard fiber optic interface. When the second interface nut 270 is fixedly connected to the adapter of the second optical cable, it can ensure that the optical fiber 220 at the end of the second fiber optic pin 250 is exactly aligned and connected with the optical fiber in the second optical cable.

[0056] Further, such as Figure 3As shown, the outer wall of the first optical fiber pin 240 is provided with a first flange 242, and the outer wall of the second optical fiber pin 250 is provided with a second flange 252; the end of the first interface nut 260 close to the connector body 210 is fixedly connected to the first flange 242, and the end of the first interface nut 260 away from the connector body 210 is a first connection opening 261, the inner diameter of the first interface nut 260 is larger than the outer diameter of the first optical fiber pin 240, and the inner wall of the first interface nut 260 is provided with an internal thread; the end of the second interface nut 270 close to the connector body 210 is fixedly connected to the second flange 252, and the end of the second interface nut 270 away from the connector body 210 is a second connection opening 271, the inner diameter of the second interface nut 270 is larger than the outer diameter of the second optical fiber pin 250, and the inner wall of the second interface nut 270 is provided with an internal thread.

[0057] The interior of the first interface nut 260 and the interior of the second interface nut 270 are hollow, and the inner diameters are respectively larger than the outer diameters of the first optical fiber pin 240 and the second optical fiber pin 250. The inner side walls of the first interface nut 260 and the second interface nut 270 are both provided with internal threads, and the connection openings of the first interface nut 260 and the second interface nut 270 are both far away from the connector body 210. When the optical fiber connector 200 is docked with the first optical cable and the second optical cable, the adapter of the first optical cable is inserted into the first connection opening 261 of the first interface nut 260 and threadedly connected to the inner side wall of the first interface nut 260, and the adapter of the second optical cable is inserted into the second connection opening 271 of the second interface nut 270 and threadedly connected to the inner side wall of the second interface nut 270, so as to realize the fixed connection between the optical fiber connector 200 and the first optical cable and the second optical cable.

[0060] Because the aperture of the first through hole 241 in the first optical fiber pin 240 for installing the optical fiber 220 is small and the length is long, a first countersunk hole is provided at the end of the first optical fiber pin 240 to reduce the length of the first through hole 241 and facilitate the processing of the first through hole 241; similarly, a second countersunk hole is provided at the end of the second optical fiber pin 250 to facilitate the processing of the second through hole 251. In addition, the first through hole 241 and the second through hole 251 are processed, and in order to facilitate the installation of the optical fiber 220 in the first through hole 241 and the second through hole 251, the aperture of the first through hole 241 and the second through hole 251 will be slightly larger than the outer diameter of the optical fiber 220, and the optical fiber 220 can slightly shake radially in the first through hole 241 and the second through hole 251. By setting the first optical fiber fixing ring 280 and the second optical fiber fixing ring 290, and the inner diameter of the first optical fiber fixing ring 280 and the second optical fiber positioning ring 290 is the same as the outer diameter of the optical fiber 220, the optical fiber 220 can be positioned to ensure that when the optical fiber connector 200 is connected to the first optical cable and the second optical cable, the optical fiber 220 in the optical fiber connector 200 is aligned with the optical fiber in the first optical cable and the second optical cable, thereby improving the alignment accuracy and reducing the reflection loss.

[0061] Furthermore, the end face of the first fiber optic pin 240 away from the connector body 210, the end face of the first fiber optic fixing ring 280 and the end face of one end of the optical fiber 220 are all flush; the end face of the second fiber optic pin 250 away from the connector body 210, the end face of the second fiber optic fixing ring 290 and the end face of the other end of the optical fiber 220 are all flush, so as to facilitate the docking of the optical fiber 220 in the fiber optic connector 200 with the optical fibers in the first optical cable and the second optical cable.
