Description

Exchangeable polarity communication connector

This creation belongs to the field of communication connectors, especially for a interchangeable polarity communication connector structure that facilitates polarity exchange work, and greatly improves the convenience of operation.

According to the traditional network communication technology, the copper wire is used as the medium for transmitting signals. However, the transmission of the copper wire must consider several things: 1. The distance of transmission, since the transmission signal of the copper wire is a charged signal, it is limited by copper. The diameter of the wire and its own resistance, the longer the transmission distance, the more obvious the signal attenuation, and the problem of poor signal; 2, the transmitted noise, and the general copper wire is a network route made by twisting the 8-core wire. When the live signal is transmitted over the network, noise is generated due to electromagnetic interference, especially in the case of high-frequency signal transmission, the noise will be more and more affected by the transmission bandwidth. In recent years, in order to accelerate the transmission of network signals, fiber-optic networks have been further developed. Fiber-optic networks have the following advantages: 1. The transmission speed of optical signals is faster than that of electrical signals; 2. The attenuation of optical signals is lower than that of electrical signals; 3. The distance traveled by fiber is much longer than the distance of copper wire. Therefore, the optical fiber network has gradually become the mainstream of network communication. However, the use of optical fiber as the transmission medium differs from the general copper wire in that the two ends of the copper wire are respectively connected to a signal transmission receiver, so that the same copper wire can simultaneously serve as a communication device. The task of transmission; conversely, in order to transmit signals over long distances, the optical fiber transmits light that is more energetic, and cannot be used together with the receiver. Therefore, when transmitting optical signals using optical fibers, it must be For transmission, that is, while transmitting on the other side, the so-called polarity in the fiber transmission system is produced.

However, the general optical fiber transmission needs to be doubled. Therefore, the design of the communication connector combines the two connectors into a duplex communication connector, but it is limited by the polarity problem. When docking, special care must be taken not to reverse the connection, otherwise the optical fiber transmission may be caused. Damage to the unit or receiver. For this reason, when it is found that the polarity of the optical fiber is wrong, it is necessary to quickly interchange the joints on both sides. The conventional method is to use the detachable upper and lower covers, and a matching embedded card structure is provided therebetween, when the two-side connector is interchanged. When you only need to separate the upper and lower covers and adjust the connectors on the left and right sides.

For example, the "Detachable fiber optic connector" of the U.S. Patent No. 7,712,970 discloses that the two optical fiber plugs are assembled into one body through an upper and lower cover, and have mutually engaged structures on the two sides of the upper and lower covers, respectively. In this way, it is necessary to pay attention to the fact that the upper and lower covers cannot be lost when the dressing is changed. Because the space of the machine room is small, most of the operators work in a very small space. This separate design pays special attention to this. a little.

Or, as disclosed in U.S. Patent No. 8,152,385, "Duplex fiber optic assemblies suitable for polarity reversal and methods therefor", U.S. Patent No. 8,678,669, "Reconfigurable polarity detachable connector assembly" and U.S. Patent No. 8,727,638 "Fiber channel-interchangeable fiber optic" "connector", which uses the upper and lower shells to first clamp and fix the two-fiber plug, and covers the upper and lower shells through a sliding cover to adjust the polarity, then the slider is opened to make the upper The lower case is in a loose state, and the two fiber plugs are axially rotated by 180 degrees, and then the slide cover is pushed back to fix the positions of the upper and lower shells to complete the work of adjusting the polarity. However, the disadvantage of this design is that when the polarity is exchanged, the optical fiber plug rotates together with the optical fiber line, so that the optical fiber wire may be shortened due to twisting, resulting in incorrect positioning after reassembly or damage to the optical fiber. Line and other issues.

Or, as in the US Patent No. 8,834,038, "Fiber optic connector" After the two non-elastic optical fiber plugs are covered by an outer casing, a spring mechanism is disposed on the outer casing, and the elastic mechanism has two hooks extending toward the optical fiber plug, and the two hooks can be utilized. Inserting and fixing with a fiber optic socket, when it is necessary to exchange the polarity of the fiber, it is only necessary to pull the spring mechanism to the opposite side of the casing. This structure is the easiest of the above-mentioned patents, and because the overall flipping has a torsion problem, the twist can be evenly distributed over the entire fiber optic line, the damage is slightly twisted, or the exchange twist is small; Because of the simple structure, the problem that the shrapnel structure may face when the shell is pulled out is that the shrapnel structure is easy to fly out, and if it is in the construction environment, it may cause loss.

All of the above disclosed communication connectors are structurally modified by the original communication connector, and there is no versatility for the communication connectors that have been installed in the early days, and all replacements are time consuming and laborious. It is also quite inconvenient for the machine room builders, so it is necessary to improve.
