Description

Optical fiber signal transmission jumper wire joint structure

Technical Field

The utility model relates to the field of communication connectors, in particular to an optical fiber signal transmission jumper wire joint structure which can quickly perform conversion work of a pair of optical fiber plugs for optical signal transmission without plugging, and the operation mode of the original jumper wire adjustment is changed by matching among a joint body, the optical fiber plugs and a sliding sleeve, so that the convenience in field operation is greatly improved.

Background

In the existing network communication technology, a copper wire is generally used as a transmission medium, and the transmission mode is to transmit signals of 0 and 1, and two ends of the copper wire are respectively connected with a signal transceiver to generate signals of 0 and 1 to be transmitted and receive signals of 0 and 1 transmitted from the other end. However, several things must be considered in the transmission of copper wires: 1. the transmission distance is that the signal transmitted by the copper wire is a live signal, the copper wire is limited by the diameter of a copper wire of a carrier of the copper wire, and the copper wire is provided with a resistor, when the transmission distance is too long, the resistor consumes the transmitted electric energy, and the signal transmitted to a receiver at the other end is poor; 2. noise during transmission is known to generate electromagnetic effect when electricity travels on a copper wire, and a network transmission of a general copper wire adopts a network line of 8 core wires, two pairs of twisted wires into four pairs of twisted wires, so that the 8 core wires interfere with each other during transmission, although a designed signal transceiver cancels or eliminates interfering signals, when the frequency is higher and higher, the noise of the generated signals is more and more extensive, which makes the elimination more difficult, and further affects the bandwidth of the network during transmission. In view of the above, a transmission method for transmitting optical signals by using optical fibers is finally developed, which has the following advantages: 1. optical transmission signals are faster than electrical; 2. the attenuation of light is lower than electricity; therefore, the distance of the optical fiber for transmitting signals is far longer than that of the copper wire, the speed is higher, and the transmission quantity of the signals is better. Therefore, optical fiber networks are becoming 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 transmitting signals to and from, and conversely, in the optical fiber transmission system, two ends of the optical fiber are not used for transmitting and receiving the signals, but the optical fiber adopts a mode that one end is used as a transmitter and the other end is used for transmitting the signals, because the optical fiber transmission system is used for transmitting the signals for a long distance, the light transmitted by the optical fiber is not the light generally used by us, but the laser light with larger energy, so that the laser transmitter and the receiver cannot be integrated into a whole, so that the optical fiber transmission system must transmit by using double optical fibers when transmitting the signals, one is responsible for transmitting, and the other is responsible for receiving, so as to avoid the confusion of the optical signals. Because of this, the optical fiber connector usually combines two connectors together, so called duplex optical fiber connector, is limited by the transmitting end and the receiving end during optical signal transmission, so that special attention is needed when the optical fiber line is connected to the optical fiber plug, and if the left and right optical fiber connectors are connected reversely, the damage to the optical fiber transmitter or the optical fiber receiver will be caused; for this reason, various connector products have been developed which can perform a quick switching of a transmitting terminal and a receiving terminal during a jumper operation.

Such as: US7,712,970 entitled "Detachable fiber optic connector" discloses a fiber optic connector structure for assembling two fiber optic plugs together by means of an upper cover and a lower cover, wherein the upper cover and the lower cover have two structures engaging with each other at both sides, so that when the jumper operation is exchanged, the upper cover and the lower cover can be separated, the left and right fiber optic plugs can be separated and adjusted in position, and the upper cover and the lower cover can be fixed together again to complete the jumper operator.

For another example: U.S. Pat. No. 8,8,152,385 discloses a fiber optic connector using a fixing structure, a groove is formed on the left and right sides for clamping two fiber optic plugs, the fixing structure is matched with the two grooves to make the fiber optic connector rotate in the axial direction, and finally the fixing structure is sleeved in a sleeve to form a fixing.

Or as follows: US8,678,669 entitled "Reconfigurable polar separable connector assembly" discloses a method for clamping two optical fiber plugs between an upper cover and a lower cover, the upper cover having an elastic hook, and a sliding cover mounted on the lower cover, wherein the sliding cover can slide backwards after pressing the elastic hook, so that the two optical fiber connectors are exposed and the exchange operation of jumper operation is performed, and the sliding cover is pushed back forwards again to complete the original position. This case has a relatively large problem in that the optical fiber connector moves together with the optical fiber lines when the exchange is performed, so that the two optical fiber lines are twisted during the exchange, and there is a problem in that the optical fiber lines may be incorrectly positioned during the reassembly due to the shortened twist, and the optical fiber lines may be easily damaged.

Or as follows: US8,727,638 patent US8,727,638 "Fiber-exchangeable Fiber optical coupler", two Fiber connectors are assembled at the front end of a fixed housing formed by combining an upper cover and a lower cover, the rear ends of the upper cover and the lower cover are both provided with an elastic hook, in addition, a housing having a slot at the upper and lower ends is covered at the outer end of the fixed housing formed by combining the upper cover and the lower cover, and the slot is combined with the elastic hook on the upper cover and the lower cover, when the polarity is exchanged, the elastic hook is separated from the slot of the housing to make the housing pulled backwards, then the Fiber connectors are respectively turned over by 180 ° in the axial direction, the housing is turned over by 180 ° and then pushed back to the original position, and the exchange action of the jumper operation of the Fiber connectors is completed. However, when the two optical fiber connectors are turned 180 ° with respect to each other, there is also a problem that the optical fiber wires are twisted and may be damaged.

Or as follows: in US8,834,038, two non-elastic optical Fiber connectors are covered by a housing at the front end of the housing, an elastic mechanism is disposed on the housing, and the elastic mechanism has two hooks extending toward the optical Fiber connectors, and the hooks can be mutually embedded and clamped with the optical Fiber sockets. This structure is the simplest compared to the above mentioned patents, and because the overall flip has twisting problems, the twisting can be evenly distributed over the entire fiber line, the damage is smaller than the individual twist, or the exchange twist; however, due to the simple structure, the spring structure may be easily broken out when the housing is pulled out, which may cause a loss problem in a construction environment.

In the US7,712,970 case, the upper cover and the lower cover should be separated during the jumper operation, which is simple in structure, but the upper cover or the lower cover is lost and cannot be used because the construction environment is messy during the machine room construction; although the problem of losing the upper and lower covers can be avoided in US8,152,385, the assembly and production are inconvenient due to the complicated structure, and the manufacturing cost is relatively increased.

Although the structure of US9,625,658 has improved the above design, it has the disadvantage that the upper spring plate extends from back to front, and the fixing place with the main body is at the back end, so the front end has the problem that the front end connector head and the spring plate may have position deviation. In addition, because the volume of the optical fiber plug is smaller than that of the existing network plug, the density of the optical fiber plug is denser than that of the network plug, and fingers are not easy to extend into the optical fiber plug.

In view of the above, the various disclosed optical fiber connectors are structurally modified from the original optical fiber connectors, and cannot be completely different from the optical fiber connectors installed in the early stage, and it is time-consuming and laborious to replace all the optical fiber connectors, which is inconvenient for the machine room constructors, so it is necessary to improve the optical fiber connectors.
