[0002] A fiber optic connector is a pluggable connector based on a single-core plug and adapter. The fiber optic connector precisely aligns the two end faces of the optical fiber. The most important thing is to align the axes of the two optical fibers so that the light energy output from the transmitting fiber can be coupled to the receiving fiber to the maximum extent and the impact on the system caused by its intervention in the optical link can be minimized. Grouped fiber optic connectors can connect multiple groups of optical fibers.

[0003] In existing technologies, group-type fiber optic connectors typically connect fiber optic cables by directly plugging them into the connector. This connection method is not stable enough, and the fiber optic cables are prone to detachment when subjected to external pulling, affecting the connection effect. Utility Model Content

The housing is mounted on the connectors. A cover plate is fastened to the upper side of the housing. Two U-shaped plates are mounted on the upper side of the cover plate. A positioning component is provided on the upper side of the housing for positioning the U-shaped plates. A plurality of slide rails are mounted on the inner bottom wall of the housing and the lower side of the cover plate. An abutment limiting seat is slidably connected to the slide rail and is capable of sliding horizontally along the slide rail. A buffer reset mechanism is provided on the inner bottom wall of the housing and the lower side of the cover plate. The buffer reset mechanism is connected to the abutment limiting seat and is used for buffering and automatically returning the abutment limiting seat to its original position.

[0006] In a preferred embodiment of the grouped fiber optic movable connector of this utility model, in order to achieve auxiliary positioning of the cover plate and ensure the stability of the cover plate after it is fastened to the housing, a positioning sleeve is installed on the upper side of the connector, and a positioning rod is installed on the upper side of the cover plate. The positioning rod is inserted into the inside of the positioning sleeve and can move vertically inside the positioning sleeve.

[0007] The positioning assembly includes a U-shaped frame, an adjusting rod, a compression ring, and a positioning spring. The U-shaped frame is mounted on the upper side of the housing. The adjusting rod is inserted into one of the two sides of the U-shaped frame and can move horizontally inside the U-shaped frame. Two compression rings are sleeved on the adjusting rod in a symmetrical manner. Two positioning springs are sleeved on the adjusting rod, and the two ends of the two positioning springs are respectively connected to the corresponding U-shaped frame and the compression ring.

[0008] As a preferred embodiment of the grouped fiber optic movable connector of this utility model, in order to achieve the insertion and positioning between the U-shaped frame and the U-shaped plate and ensure the stability of the cover plate after fastening, a positioning slot is provided on one side of the U-shaped plate and the U-shaped frame, and the inner diameter of the positioning slot is adapted to the outer diameter of the adjusting rod.

[0009] As a preferred embodiment of the grouped fiber optic movable connector of this utility model, in order to achieve sliding limit of the abutment limiting seat and ensure the stability of the abutment limiting seat during sliding, the number of slide rails is four, and the four slide rails are symmetrically arranged on the housing and the cover plate, and the shape of the slide rails is I-shaped.

[0010] The buffer reset mechanism includes a mounting base, guide posts, a connecting base, and a buffer reset spring. The mounting base is installed on the inner bottom wall of the housing and the lower side of the cover plate. Two guide posts are installed inside the mounting base, and the two guide posts are symmetrically arranged inside the mounting base. The connecting base is sleeved on the guide posts and can move horizontally along the guide posts. The connecting base is connected to the abutment limiting seat. The buffer reset spring is sleeved on the guide posts, and the two ends of the buffer reset spring are respectively connected to the mounting base and the connecting base.

[0030] like Figures 1-4 As shown, this embodiment illustrates a grouped fiber optic movable connector, including a main body 1 and connectors 2. The main body 1 is provided with multiple connectors 2, and also includes a housing 3, a cover plate 4, a U-shaped plate 5, a positioning component, a slide rail 6, an abutment limiting seat 7, and a buffer reset mechanism. Compared to existing grouped fiber optic movable connectors, which typically involve directly inserting the fiber optic cable into the connector, this connection method is not stable enough, and the fiber optic cable is prone to detachment when subjected to external pulling, affecting the connection effect. In this embodiment, the slide rail 6, the abutment limiting seat 7, and the buffer reset mechanism work together to achieve stable connection of the fiber optic cable inserted into the connector 2. The contact limit ensures the stability of the fiber optic cable after it is plugged into connector 2, reduces the probability of the fiber optic cable falling off due to external pulling, and ensures the connection effect of the fiber optic cable. The buffer reset mechanism realizes the buffer and automatic reset of the fiber optic cable after being pulled by external force, avoiding the probability of the fiber optic cable breaking due to excessive external force. The detachable cover plate 4 realizes the quick installation or removal of the buffer reset mechanism located at the top, which facilitates the staff to plug or unplug the fiber optic cable. The cooperation of the U-shaped plate and the positioning component realizes the positioning of the cover plate 4 after it is fastened, ensuring the stability of the cover plate 4 after it is fastened, thereby ensuring the limiting effect of the limiting mechanism located at the top.

[0031] like Figure 1 and Figure 4As shown, the housing 3 is mounted on the connector 2. A cover plate 4 is fastened to the upper side of the housing 3. A positioning sleeve 8 is installed on the upper side of the connector 2. A positioning rod 9 is installed on the upper side of the cover plate 4. The positioning rod 9 can be inserted into the inside of the positioning sleeve 8 to position the cover plate 4 after fastening, ensuring the stability of the cover plate 4 after fastening. Two U-shaped plates 5 are installed on the upper side of the cover plate 4. A positioning assembly is provided on the upper side of the housing 3. The positioning assembly includes a U-shaped frame 101, an adjusting rod 102, a compression ring 103, and a positioning spring 104. A positioning insert is provided on one side of the U-shaped plate 5 and the U-shaped frame 101. The inner diameter of the positioning slot is adapted to the outer diameter of the adjusting rod 102. The adjusting rod 102 can position the U-shaped plate 5 and the U-shaped frame 101 through the positioning slot, thereby realizing the positioning of the cover plate 4 after it is fastened. The detachable cover plate 4 can realize the quick installation or removal of the upper limiting mechanism, thereby facilitating the staff to insert or remove the fiber optic cable. The cooperation between the U-shaped plate 5 and the positioning component realizes the positioning of the cover plate 4 after it is fastened, ensuring the stability of the cover plate 4 after it is fastened, and ensuring the limiting effect of the upper limiting mechanism on the fiber optic cable inserted into the connector 2.

[0032] like Figure 2 As shown, multiple slide rails 6 are installed on the inner bottom wall of the housing 3 and the lower side of the cover plate 4. There are four slide rails 6, symmetrically arranged on the housing 3 and cover plate 4. The slide rails 6 are I-shaped and can slide and limit the contact limiting seat 7, thus ensuring the stability of the contact limiting seat 7 during sliding. The contact limiting seat 7 is slidably connected to the slide rail 6. Anti-slip pads are provided on the inner side of the contact limiting seat 7, increasing the friction between the contact limiting seat 7 and the fiber optic cable, thus ensuring the contact limiting effect of the contact limiting seat 7 on the fiber optic cable. A buffer reset mechanism is installed on the inner bottom wall of the housing 3 and the lower side of the cover plate 4, and the buffer reset mechanism is connected to the contact limiting seat 7. Figure 3 As shown, the buffer reset mechanism includes a mounting base 201, a guide post 202, a connecting base 203, and a buffer reset spring 204. Two buffer blocks 10 are installed on the side of the mounting base 201 near the abutment limit seat 7. The two buffer blocks 10 are symmetrically arranged on the mounting base 201. The buffer blocks 10 can buffer the abutment limit seat 7 and the mounting base 201, avoiding direct collision between the abutment limit seat 7 and the mounting base 201. The cooperation of the slide rail 6, the abutment limit seat 7, and the buffer reset mechanism can realize the abutment limit of the optical fiber cable inserted into the connector 2, reducing the probability of the optical fiber cable falling off due to external force.

[0033] Working principle:

[0034] When it is necessary to connect the fiber optic cable, the operator pulls the adjusting rod 102 to pull it out from the U-shaped plate 5 and the U-shaped frame 101, thus canceling the positioning of the adjusting rod 102 between the U-shaped plate 5 and the U-shaped frame 101. After cancellation, the operator removes the cover plate 4 from the housing 3. After cancellation, the operator moves the abutment limit seat 7 along the slide rail 6 to the mounting base 201. After sliding to the corresponding position, the operator inserts the fiber optic cable to be connected into the connector 2. After insertion, the operator releases the abutment limit seat 7, and the lower abutment limit seat 7 abuts against the plug of the fiber optic cable. Then, the operator fastens the cover plate 4 onto the housing 3. After the cover plate 4 is fastened, the upper abutment limit seat 7 abuts against the plug of the fiber optic cable, thus achieving the abutment limit of the fiber optic cable plug inserted into the connector 2. Then, the positioning component positions the U-shaped plate 5.

[0035] When the fiber optic cable is pulled by an external force, the plug of the fiber optic cable moves under the influence of the tension. The plug causes the abutment limit seat 7 to slide along the slide rail 6. The abutment limit seat 7 causes the connector 203 to slide along the guide post 202. The connector 203 compresses the buffer reset spring 204. During the sliding process, the abutment limit seat 7 stops sliding after contacting the buffer block 10. The buffer block 10 can ensure that the plug does not fall off the connector 2. When the pulling force disappears, the buffer reset spring 204 causes the connector 203 to return to its original position. The connector 203 causes the abutment limit seat 7 to push the plug back to its original position.
