Description

Switched polarity optical fiber network jumper connector structure

This creation belongs to the field of communication connectors, especially a switchable polarity optical fiber network jumper connector structure that can quickly adjust the polarity, change the original operation method when the polarity adjustment is performed, and greatly improve the convenience of on-site operation. .

According to the conventional network communication technology, copper wires are generally used as the transmission medium. The transmission method is to transmit signals of 0 and 1, and a signal transmitter and receiver are connected to both ends of the copper wire to generate The signals of 0 and 1 are sent out, and the signals of 0 and 1 from the other end are received. However, several things must be considered in the transmission of copper wire: 1. The transmission distance, because the signal transmitted by the copper wire is a live signal, and the copper wire is limited by the diameter of its carrier copper wire, and the copper wire itself has When the transmission distance is too long, the resistance will consume the transmitted power, which will cause the signal to the receiver at the other end to be poor; 2. Noise during transmission, as we all know, when electricity travels on copper wires When transmitting, it will produce electromagnetic effects, and the general copper wire network transmission uses 8 core wires twisted in two pairs into four pairs of wires. Therefore, the 8 core wires will interfere with each other during transmission, although it is designed The signal transmitter and receiver will cancel or eliminate the interference signal, but when the frequency gets higher and higher, the noise of the generated signal will become more and more widespread, making it more difficult to eliminate, which will affect the network's transmission. bandwidth. In view of this, a transmission method that uses optical fibers to transmit optical signals is finally developed. The advantages are: 1. Optical transmission signals are faster than electricity; 2. Light attenuation is lower than electricity; therefore, the distance of optical fiber transmission signals is much longer than that of copper. The wire transmits the signal over a long distance, its speed is also faster, and the signal transmission capacity is better. Therefore, optical fiber networks have gradually become the mainstream, but the most fundamental difference between optical fiber transmission and copper wire transmission is that the same copper wire can simultaneously perform the task of signal transmission. On the contrary, in the optical fiber transmission system, the two ends of the optical fiber are not transmitting and receiving. Together with the transmitter, one end is the transmitter and the other end is the receiver for signal transmission. This is because the optical fiber transmission system can transmit signals over long distances, so the light transmitted by the optical fiber is not the light we generally use. , It’s the laser light with greater energy, so the laser transmitter and receiver cannot be integrated. The optical fiber transmission system must use a pair of optical fibers to transmit signals when transmitting signals. The so-called polarity in the optical fiber transmission system. Because of this, the optical fiber connector usually combines two connectors, so it is called a duplex optical fiber connector. It is limited by the polarity during transmission, so that the optical fiber cable must be paid special attention when connecting the optical fiber plug. Enough to connect the left and right fiber ends upside down will damage the transmitter or receiver of the fiber. For this reason, we have developed a variety of connector products that can quickly exchange the connectors on both sides when the polarity of the fiber is found to be wrong.

For example, US patent US7,712,970 "Detachable fiber optic connector" discloses a fiber optic connector structure that assembles two optical fiber plugs through an upper cover and a lower cover. The upper cover and the lower cover have two mutual With the snap-fit structure, when the polarity is exchanged, the upper cover and the lower cover can be separated, and the left and right optical fiber plugs can be re-covered in the swap position.

Another example: US patent US8,152,385 "Duplex fiber optic assemblies suitable for polarity reversal and methods therefor", its optical fiber connector is disclosed using a fixed structure, and a groove is formed on the left and right sides for securing the two optical fibers. The plug is matched with the two grooves by the fixing structure, so that the optical fiber connector can be rotated in the axial direction, and finally the fixing structure is sheathed in a sleeve to form a fixation.

Or for example: US Patent No. 8,678,669 "Reconfigurable polarity detachable connector assembly" discloses a method for sandwiching two optical fiber plugs between an upper cover and a lower cover, and the upper cover has an elastic hook, and then a sliding cover is assembled on On the lower cover, when the elastic hook is pressed, the sliding cover can be slid backwards, so that the two optical fiber connectors are exposed and the polarity exchange action is performed, and then the sliding cover is pushed back to the original position again to complete. The big problem in this case is that when the polarity is exchanged, the optical fiber connector and the optical fiber cable move together. Therefore, the two optical fiber cables will be twisted during the exchange, which may cause the optical fiber cable to be shortened due to the twist and form a reassembly time. The position is not correct, and the problem of easy damage to the optical fiber cable exists.

Or for example: US patent US8,727,638 "Fiber channel-inter changeable fiber optic connector", two fiber optic connectors are assembled at the front end of a fixed shell formed by the combination of upper and lower covers, and there is a flexible hook on the back end of the upper and lower covers. The shell with upper and lower slots is wrapped around the outer end of the fixed shell formed by the combination of the upper and lower covers, and the slot is combined with the elastic hooks on the upper and lower covers. When the polarity is exchanged, the elastic hooks are separated from the slots of the shell. The shell can be pulled back, and then the optical fiber connectors are turned 180° in their axial directions. Similarly, the shell is turned 180° and pushed back to the original position to complete the fiber polarity exchange action. However, when the two optical fiber connectors are relatively rotated by 180°, there will also be the problem of torsion of the optical fiber, and the problem of damage to the optical fiber.

Or for example: US patent US8,834,038 "Fiber optic connector", two non-shrapnel fiber optic connectors are covered with a shell on the front of the shell, a spring mechanism is arranged on the shell, and the spring mechanism has hooks extending in the direction of the fiber optic connector. , The hook can be embedded and locked with the optical fiber socket. When the polarity is changed, only the shrapnel mechanism needs to be pulled up and replaced on the opposite side of the housing. Compared with the above-mentioned patent, this structure is the simplest, and because the overall flipping will have torsion problems, the torsion can be evenly distributed across the entire optical fiber line, and the damage is smaller than individual twisting or exchange twisting; however, Because of the simple structure, the problem that the shrapnel structure may face when pulling out the shell is that the shrapnel structure is easy to fly out, and it may cause loss in the construction environment.

In the aforementioned US7,712,970 case, the cover and the lower cover must be separated during use. The structure is simple. However, during the construction of the machine room, the construction environment is often messy. If the upper or lower cover is lost, it cannot be used; and US8, Although the 152,385 case could avoid the problem of missing upper and lower covers, the complicated structure caused inconvenience in assembly and production, and relatively increased manufacturing costs.

Although the structure of US9,625,658 has improved the lack of the above design, the disadvantage is that because the upper shrapnel extends from back to front, and the fixation with the main body is located at the back end, the front end may have the connector head and shrapnel. The problem of positional deviation exists. In addition, because the volume of the optical fiber plug is smaller than that of the existing network plug, and the density is denser than that of the network plug, it is more difficult to get your fingers in.

In view of this, the above-mentioned various optical fiber connectors that have been disclosed are all structurally modified from the original optical fiber connectors, and cannot be completely non-universal with the earlier installed optical fiber connectors, and all of them can be replaced. It will be time-consuming and laborious, and it is also quite inconvenient for the construction personnel of the machine room, so it is necessary to improve it.

In view of this, one purpose of this creation is to provide a switchable polarity optical fiber network patch cord connector structure, so that a sliding sleeve can be used to assemble a connector body from back to front, and the sliding sleeve can be left during operation. In the optical fiber socket, it provides a return method after steering and exchange, which greatly improves the convenience of on-site operation.
