[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to Figures 1 to 8 , the present application discloses a single-core single-mode low-loss ferrule, including a ferrule base 1, a ferrule body 2 disposed on the upper part of the ferrule base 1, a plurality of uniformly arranged optical fiber jacks 3 are disposed on the ferrule body 2, and a control hole 4 is disposed on one side of the optical fiber jack 3;

[0032] Among them, the optical fiber jack 3 includes: a buffer slot 41 for docking with a connector plug, a connection jack 42 disposed at the central position of the buffer slot 41, a plurality of connection grooves 420 are disposed inside the connection jack 42 along the inner wall of the connection jack 42, a positioning groove 421 is horizontally disposed in the connection groove 420, and fixing grooves 423 and through holes 422 are disposed at both ends of the positioning groove 421, and the through hole 422 communicates with the control hole 4;

[0033] An elastic contact block 5 is arranged in each connecting groove 420. An installation block 52 is arranged at the rear end of the elastic contact block 5. A clamping structure block 54 and a cylindrical insertion bar 53 are respectively arranged at both ends of the installation block 52.

[0034] The clamping structure block 54 is installed in the fixing groove 423. The cylindrical insertion bar 53 is inserted into the through hole 422 and extends to the control hole 4, and is connected to the conductive electrode 63 arranged in the control hole 4.

[0035] An independent switch assembly 6 is arranged in each control hole 4. The switch assembly 6 includes a plurality of conductive electrodes 63, a sliding resistor 64 connected to the conductive electrodes 63, and a switch controller 60 connected to the sliding resistor 64. The switch controller 60 is connected to the main controller through a circuit. The main controller controls the switch controller 60 to selectively connect to the conductive electrode 63 according to the access signal obtained by the switch controller.

[0036] In the above, the master controller forms a control signal for selectively accessing the conducting electrode 63 by the switch controller based on at least one set of access signals obtained by the switch controller, so as to avoid conflicts in the access signals of the same switch controller 60. Specifically, the master controller receives multiple sets of access signals obtained by the same switch controller, generates an access control signal and at least one inhibition control signal by the master controller according to the access signals, and sends the formed access control signal and at least one inhibition control signal to the same switch controller 60. The switch controller 60 controls one of the plurality of sliding resistors 64 according to the access control signal to connect the connection between the conducting electrode 63 and the cylindrical insert 53, and the remaining ones control the remaining sliding resistors through the inhibition control signal to block the connection between the conducting electrode 63 and the cylindrical insert 53. The present application changes the single contact formed by the traditional single jack of the ferrule to transmit signals into multi-point contacts. When one of them fails to transmit signals, the feedback data obtained by the master controller according to the access signals can be automatically adjusted to change the original access rules. Therefore, it is possible to complete the re-access of signals without replacement. The present application can greatly reduce the signal access interruption caused by insertion loss. At the same time, in order to facilitate the management of multi-point contacts, the master controller receives multiple sets of access signals obtained by the same switch controller, generates an access control signal and at least one inhibition control signal by the master controller according to the access signals, and sends the formed access control signal and at least one inhibition control signal to the same switch controller. The switch controller controls one of the plurality of sliding resistors according to the access control signal to connect the connection between the conducting electrode and the cylindrical insert, and the remaining ones control the remaining sliding resistors through the inhibition control signal to block the connection between the conducting electrode and the cylindrical insert. That is to say, during access, the access management is carried out normally according to the beacon signal recorded during access. That is to say, after one access initialization, no signal inhibition action is required for re-access, and the inhibition will be automatically completed according to the record. However, once the normally open path is damaged, one of the inhibition routes can be connected under the master controller.

[0037] In the above, the switch controller 60 and the conducting electrode 63 are accessed through different pins, and the switch controller 60 generates a beacon signal according to the position of the pins, and judges and identifies the access signal transmitted from the cylindrical insert 53 through the conducting electrode 63 and the sliding resistor 64 to the switch controller 60 according to the beacon signal.

[0038] In the above, the connection groove 420 is horizontally opened along the inner wall of the connection jack 42. Each connection groove 420 forms at least a half circle same as the connection jack 42 along the horizontal direction of the inner wall of the connection jack 42. The connection grooves 420 arranged up and down are staggeredly arranged, and the connection grooves 420 arranged up and down form at least a circle layout same as the connection jack 42 along the top view projection of the connection jack 42. The purpose of such a setting is to facilitate the insertion management of the conductive electrode 63, so that different conductive electrodes 63 are kept in the same straight line in the vertical direction. Among them, the through holes 422 opened in the staggeredly arranged connection grooves 420 are on the same vertical line. Correspondingly, after the elastic contact block 5 is installed, at least one circle is formed by the two arc-shaped elastic pieces 50 protruding forward and arranged up and down in a staggered manner, and the two compression spaces 55 up and down form a contact circle.

[0039] In the above, a forward-protruding arc-shaped elastic piece 50 is arranged at the front end of the elastic contact block 5. The arc-shaped elastic piece 50 completely covers the connection groove 420. An inwardly concave contact adaptation groove 51 is arranged in the middle of the arc-shaped elastic piece 50. The mounting block 52 arranged at the rear end of the elastic contact block 5 has two elastic pieces 56 in a shape of an inverted V. A compression space 55 is formed between the elastic pieces 56. The clamping structure block 54 and the cylindrical insert 53 are respectively arranged in the compression space 55 and are integrally arranged with the rear end of the arc-shaped elastic piece 50.

[0040] Among them, the clamping structure block 54 and the cylindrical insert 53 are arranged in the compression space 55 so that the compression space 55 has a set allowance of moving space when the elastic piece 56 is squeezed.

[0041] It should be noted that the above elastic contact block 5 is made of copper material as a whole.

[0042] In the above, several conductive electrodes 63 arranged on the switch assembly 6 penetrate into the through holes 422 to form a butt joint with the cylindrical insert 53, and the conductive electrodes 63 arranged up and down are isolated by a circular isolation plate 61. Among them, the conductive electrode 63 is connected to the conductive column 62.

[0043] In the above, the total controller is built-in with a memory model. The memory model is used to synchronize beacon signals from the switch controller 60, judge and identify the access signals transmitted from the cylindrical insert 53 to the switch controller 60 through the conductive electrode 63 and the sliding resistor 64 according to the beacon signals; and mark the access signals according to the beacon signals. At the same time, access control signals and prohibition control signals are generated according to the marking records of the beacon signals, so that when accessing the access signal again, the memory model generates access control signals and prohibition control signals according to the recorded beacon signals, thereby controlling the switch controller 60 to selectively access the corresponding conductive electrode 63 according to the record.

[0044] In the above, the memory model is further provided with a detection module, and the detection module is further provided with generation rules for the access control signal and the prohibition control signal formed according to the recorded beacon signal;

[0045] And the detection module is further configured to receive the feedback data formed by the switch controller 60 executing the access control signal and the prohibition control signal, and correct the generation rules according to the beacon signal based on the feedback data.

[0046] In the above, the feedback data includes the access feedback instruction of the access control signal and the prohibition feedback instruction of the prohibition control signal when the switch controller 60 executes the access control signal and the prohibition control signal.

[0047] In the above, a docking buffer 411 is arranged in the buffer slot 41. The docking buffer 411 is cylindrical, and is provided with a buffer hole 417 for the contact post to be inserted. A spring fixing groove 416 is arranged in the buffer hole 417, and a buffer spring 415 is arranged in the spring fixing groove 416. A plurality of card slots 414 are arranged in the circumferential direction of the docking buffer 411. An extrusion spring 412 and a spring block 413 are arranged in the card slot 414. Among them, the spring block is installed in a notch 410 formed on the inner wall of the docking buffer slot 41.

[0048] When this application is in use, it needs to complete initialization under the general controller for the first time. Specifically, when it is docked with the connector plug, the corresponding pins on the connector plug are inserted through the buffer holes 417. Due to the existence of the buffer spring 415, stress contact will not be directly caused during insertion, reducing mechanical wear to a certain extent. After insertion, since the pins come into contact with multiple elastic contact blocks 5 in the same connection jack 42, multiple access signals are formed. Each access signal is actually transmitted by the conductive electrode 63 penetrating into the through hole 422 to form a butt joint with the cylindrical insert 53. At the beginning, the conductive electrode is in an open state, and each access signal can be normally accessed. Since the switch controller 60 and the conductive electrode 63 are accessed through different pins, and the switch controller 60 generates a beacon signal based on the position of the pins, and judges and identifies the access signal transmitted from the cylindrical insert 53 through the conductive electrode 63 and the sliding resistor 64 to the switch controller 60 according to the beacon signal. Therefore, during access, the access signal transmitted from the cylindrical insert 53 through the conductive electrode 63 and the sliding resistor 64 to the switch controller 60 can be judged and identified through the beacon signal. The memory model set by the general controller synchronizes the beacon signal from the switch controller 60, and judges and identifies the access signal transmitted from the cylindrical insert 53 through the conductive electrode 63 and the sliding resistor 64 according to the beacon signal; and marks the access signal according to the beacon signal. At the same time, access control signals and prohibition control signals generated according to the marks of the beacon signal are recorded, so that when accessing the access signal again, the memory model generates access control signals and prohibition control signals according to the recorded beacon signal, thereby controlling the switch controller 60 to selectively access the corresponding conductive electrode 63 according to the record. This application changes the single-contact signal transmission formed by the traditional single jack of the core into multi-point contact. When one of them cannot achieve signal transmission, the general controller can automatically adjust according to the feedback data obtained from the access signal and change the original access rule. Therefore, signal re-access can be achieved without replacement. This application can greatly reduce the signal access interruption caused by insertion loss.

[0049] The above are only partial embodiments of this application, and do not limit the patent scope of this application accordingly. Any equivalent structural transformation made under the technical concept of this application by using the content of the specification and drawings of this application, or any direct / indirect application in other related technical fields, is included in the patent protection scope of this application.
