Description

Connector system

The invention relates to a connector system, and more particularly to an optical fiber connector system.

In recent years, the amount of optical fiber used for communication purposes has been very large, and data, voice and other communication networks have increasingly used optical fibers to transmit information. Optical fibers are usually configured as glass fibers used to carry light. Individual fibers can be grouped into groups capable of carrying large amounts of data at the same time.

When constructing a fiber optic network, each fiber is usually connected to a source device and a target device. In addition, along the fiber path between the source and destination, various connections or couplings can be formed on the fiber to adjust the fiber length. Each connection or coupling requires connectors and adaptors to align the optical fibers so that light can travel without interruption.

Please refer to FIG. 1, US Patent No. 9,755,382 discloses a connector system that can be used for optical fiber and electrical conductor connector modules, in which the connector can be locked on the adapter 20 by the configured coupling nut 18, and The lock ring 26 prevents the coupling nut 18 from rotating on the connector housing, thereby preventing the connector 10 from being accidentally decoupled from the adapter 20. The operating mode of the lock ring 26 is to push the coupling nut 18 forward after the coupling nut 18 is locked into the adapter 20 to abut the coupling nut 18 to prevent the coupling nut 18 from rotating.

However, the disadvantage of the above connector design is that the user has to remember to push the lock ring 26 into position every time after the coupling nut 18 is locked. When you want to remove the connector, you need to pull the lock ring 26 back. The aforementioned complicated installation methods may cause user operation errors in bad environments, such as outdoor or high places. Furthermore, the lock ring 26 should be stopped in position under normal circumstances, but if there is a problem with the size of the lock ring or the connector body, the lock ring 26 may slide, especially when the connector is suspended vertically. In addition, if the lock ring 26 is used in the dust cover configuration, the lock ring 26 may completely slide away from the dust cover when the connector is suspended vertically. In addition, if a force is applied to the dust cover, the lock ring 26 is easier to slide. Another disadvantage of the aforementioned connector design is that there is no "click" sound or tactile feedback generated to indicate when the connector nut is fixed in place.

As shown in Figure 2, the above-mentioned matching of the connector and the adapter needs to visually determine whether the alignment pin (not shown) on the inner wall of the connector has slipped into the groove 22 on the adapter 20, if in a bad environment, for example It may be difficult for the user to pair the connector with the adapter when it is installed outdoors, in high places or in poorly-lit environments, or in a narrow space.

US Patent No. 8,272,790 discloses an outdoor transceiver connector. In its design, the connector is fixed at a proper position in the housing and cannot move independently relative to the adapter. This means that the connector housing and the adapter housing must be perfectly aligned when mating to avoid loss of optical signal. In addition, the bracket part 1304 of the connector in FIG. 2 is used to fix the connector. However, the above design is not reliable. If the component 1304 fails, the connector bracket may be pulled out. In addition, the sleeve of the connector in Figure 2 is exposed. If the user installs the connector in a poor environment, the end of the sleeve may be touched unintentionally, and the sleeve may be soiled or even damaged.

In view of this, the present invention provides a connector system in which the included connectors can move independently, so that they can be correctly aligned with the adapter.

The invention provides a connector system which restricts the accommodating shell and the sleeve system to be locked and unlocked in a rotating manner.

The present invention provides a connector system that can provide the user with tactile feedback when it reaches the locked state.

The present invention provides a connector system, which can prevent accidental impact on the optical fiber sleeve and provides the function of protecting the optical fiber sleeve.

The invention provides a dust-proof piece, which can prevent dust from polluting the optical fiber connector in the connector system.

In one embodiment, the connector system of the present invention includes a socket, a sleeve, a housing shell, a first fork and a second fork. The socket has a pairing indicator. The accommodating shell is arranged in the sleeve to accommodate the rear end of a connector.

A crack is formed in a corner of the front end of the second fork.

In still another embodiment, the connector system of the present invention includes a socket, a first sleeve, a first housing shell, a first fork, a second sleeve, a second housing shell, and a The second fork. The socket has a first end and a second end opposite to each other. The first accommodating shell is arranged in the first sleeve to accommodate the rear end of a first connector.

Similarly, if a protrusion wants to enter the second groove 240, it can only enter from the right side of the second groove 240, and can only be moved out from the right side of the second groove 240.

16a and 16b, if you want to install the sleeve 400 on the accommodating shell 200, you need to rotate the sleeve 400 so that the two protrusions 481 on the inner wall of the sleeve 400 are respectively from the right of the first groove 230 and the second groove 240 Move the notch of the sleeve into the first groove 230 and the second groove 240; and to remove the sleeve 400 from the housing shell 200, you need to rotate the sleeve 400 in the opposite direction so that the two tabs 481 are separated from the first groove 230 and the second groove 240. The notch on the right of the second groove 240 is removed, and then the sleeve 400 can be pulled, which prevents the sleeve 400 from being accidentally pulled out. After the sleeve 400 is removed from the housing shell 200, the optical fiber connector 900 can be easily cleaned.

17 and 18, according to the connector system 1000 of the present invention, the sheath 110 can be screwed on the rear part 123 of the cable connector 120. The O-ring 131 is sleeved on the front part 121 of the cable connector 120 and closely adheres to the middle part 122. The wave spring 132 is sleeved on the outer surface of the middle section of the sleeve 400. The O-ring 134 is sleeved in the annular groove 451 on the sleeve 400. The sleeve 400 is screwed with the thread on the front part 121 of the cable connector 120 by using the thread 441 to be combined with the cable connector 120 and tightly attached to the O-ring 131. The lock ring 500 is sleeved on the sleeve 400 and covers the wave spring 132. The function of the wave spring 132 is to provide the axial force of the locking shell 600 to avoid falling off from the socket 700. The alignment key 431 on the outer surface of the sleeve 400 is inserted into the alignment groove 531 of the lock ring 500. The nut 136 is locked on the socket 700 with a thread 730. The rear section of the locking shell 600 is sleeved on the sleeve 400 and the locking ring 500 and covered with an O-ring 134. The front part of the locking shell 600 is sleeved on the socket 700. The function of the O-ring 134 is to seal the gap between the sleeve 400 and the locking shell 600 to prevent water from passing through.

According to the connector system 1000 of the present invention, the optical fiber can pass through the sheath 110, the cable joint 120, the sleeve 400, the channel 225 of the housing shell 200 and the floating block 300, and finally connect to the optical fiber sleeve of the optical fiber connector 900 920. The cable can also pass through the sheath 110, the cable connector 120 and the sleeve 400, and pass through the channel 226 of the housing case 200.

19, according to the connector system 1000 of the present invention, the two forks 421, 422 at the front end of the ferrule 400 extend beyond the fiber ferrule 920 at the front end of the connector 900 to prevent accidental contact with the fiber ferrule 920. The role of protecting the fiber sleeve 920. For example, when the connector 900 is dropped, the fiber optic ferrule 920 will not directly hit the ground and be damaged. In addition, when the locking shell 600 is locked on the socket 700, there is no need to visually judge the alignment. You can align the notch 429 on the fork 421 with the recess 760 and the protrusion 770 on the socket 700 by touching it with your fingers. The forks 421 and 422 are inserted into the socket 700, and then the locking shell 600 is rotated to lock on the socket 700. The notch 429 on the fork 421 is used as an alignment indicator (alignment indicator), which can form a touch matching indicator with the recess 760 and the protrusion 770 on the socket 700. The above-mentioned "blind" installation method is particularly suitable for applications in bad environments, such as outdoors, high places or poorly illuminated environments, or installation in narrow spaces. In other embodiments of the present invention, one or both of the forks 421 and 422 may be formed on other elements, for example, may be formed on the housing case 200 to replace the forks originally formed on the sleeve 400.部421 or 422.

Please refer back to FIG. 11, according to the connector system 1000 of the present invention, there is a slight gap between the floating block 300 and the housing shell 200, so each of them can make a slight three-dimensional movement relative to the housing shell 200, and then is inserted in the floating block. The connectors 900 on the block 300 can also move independently. Therefore, when the two connectors 900 are inserted into a duplex adapter provided in the socket 700, since the slider 300 can make a slight three-dimensional movement, the two connectors 900 can be correctly aligned with the adapter. The alignment of the fiber optic connector is very important because the diameter of the single-mode fiber core is very small. In addition, the upper eaves 370 of the slider 300 can press down the latch 940 of the connector 900 so that the connector 900 can be pulled out from the adapter. The tail end of the latch 940 is placed in the skylight 372 of the upper eaves 370 to prevent the connector 900 from being separated from the floating block 300.

When assembling the connector system 1000 of the present invention, the latches 940 on the two connectors 900 are pressed down and the tail posts 930 of the two connectors 900 are respectively inserted into the two sliders 300, so that the tail ends of the two latches 940 are respectively Place it in the skylight 372 of the upper eaves 370 of the two floating blocks 300. Then, the two floating blocks 300 are inserted into the accommodating shell 200, and then the pins 270 are inserted into the two positioning openings 250 of the accommodating shell 200 to fix the two floating blocks 300. The O-ring 134 is sleeved in the annular groove 451 on the sleeve 400. Then insert the housing shell 200 into the front end of the sleeve 400, so that the two protruding pieces 481 on the inner wall of the sleeve 400 abut against the retaining walls 237 and 247 on the outer surface of the housing shell 200, and then rotate the sleeve 400 to make the two protruding The piece 481 is moved into the first groove 230 and the second groove 240 from the notches on the right side of the first groove 230 and the second groove 240 on the outer surface of the housing shell 200 to prevent the housing shell 200 from being separated from the sleeve 400 .

Then put the lock shell 600 on the lock ring 500 so that the pins 642 are placed in the lock grooves 521 on the outer surface of the lock ring 500 respectively. Then rotate the lock shell 600 and push the lock shell 600 toward the lock ring 500 so that the pins 642 are respectively rotated into the guide grooves 550, and finally the protrusions 643 are respectively rotated into the locking grooves 521. Then, the wave spring 132 is sleeved on the outer surface of the middle section of the sleeve 400, and then the alignment key 431 on the outer surface of the sleeve 400 is inserted into the alignment groove 531 of the lock ring 500. Then, the O-ring 131 is sleeved on the front part 121 of the cable joint 120, and the front part 121 of the cable joint 120 is screwed to the sleeve 400. The sheath 110 is screwed to the rear part 123 of the cable connector 120. Then align the notch 429 on the fork 421 of the sleeve 400 with the recess 760 and the protrusion 770 on the socket 700, and then insert the forks 421 and 422 into the socket 700. Then rotate the locking shell 600 so that the protrusions 641 on the inner wall slide in the grooves 750 on the outer wall of the socket 700. Finally, the locking shell 600 is locked on the socket 700 so that the connector 900 in the sleeve 400 is inserted into Adapter in socket 700. It should be noted that the end of the optical fiber connector 900 is extended with optical fibers. Therefore, when assembling the connector system 1000 of the present invention, the optical fibers need to pass through various components before assembly.

When the pins 642 of the locking shell 600 are respectively positioned in the first groove 560 of the locking ring 500, the protrusions 641 on the inner wall of the locking shell 600 will be positioned on the front part 751 of the groove 750, and the protrusions 643 will be positioned separately. In the locking groove 521. Afterwards, the locking ring 500 can be pulled backwards to allow the pins 642 to slide in the first groove 560 and pass over the protrusions 593 to the connection between the first groove 560 and the third groove 580, and the protrusions 643 will move from the locking groove 521 respectively. The notch at the front end leaves the locking groove 521. Then, the locking shell 600 can be rotated to allow the protrusions 641 to slide from the front part 751 of the groove 750 through the middle part 752 to the rear part 753 respectively. Because the lock ring 500 can only move along the longitudinal direction 191 and cannot rotate, the pins 642 of the lock shell 600 will slide from the first groove 560 into the third groove 580 when the lock shell 600 is rotated. At this time, the sleeve 400 can be pulled to make the protrusion 641 Leaving the grooves 750 respectively thus separates the connector 900 from the adapter in the socket 700.

When the connector 900 is to be inserted into the adapter in the socket 700, the locking shell 600 is rotated to turn the pins 642 into the second groove 570 respectively, and then the protrusions 641 on the inner wall of the locking shell 600 are respectively inserted into the rear section of the groove 750 Part 753. Then, the locking shell 600 is rotated to allow the protrusions 641 to slide into the middle section 752 of the groove 750 and reach the front section 751 respectively. During the rotation of the locking shell 600, its pins 642 are blocked by the gap 585 and cannot be turned back into the third groove 580, and since the lock ring 500 can only move along the longitudinal direction 191, the pins 642 will be in the second Sliding in the groove 570 and pulling the lock ring 500 toward the locking shell 600, and finally over the protrusion 575 to reach the first groove 560. When the pins 642 are respectively turned into the first groove 560, the connector 900 will be inserted into the adapter in the socket 700 to form a locked state. In addition, during the rotation of the locking shell 600, the protrusions 643 on the inner wall of the locking shell 600 will approach the locking groove 521 from the left side, and finally will cross the retaining wall on the left side of the locking groove 521 and fall into the locking groove 521 respectively. Referring back to FIG. 18, when the locked state is formed, the shoulder 631 on the inner wall of the locking shell 600 can prevent the shoulder 461 on the outer surface of the sleeve 400 from retreating, thereby preventing the sleeve 400 from being pulled out.

The gap 576 in the guide groove 550 can respectively prevent the pin 642 from moving from the first groove 560 to the second groove 570, and therefore has the function of a stopper. The retaining wall on the left side of the locking groove 521 can respectively prevent the protrusion 643 from moving out of the locking groove 521 from the left side, and therefore can also prevent the pin 642 from moving from the first groove 560 to the second groove 570 respectively. The gap 585 in the guide groove 550 can respectively prevent the pin 642 from moving from the second groove 570 to the third groove 580, and therefore has the function of a stopper.

When the user rotates the locking shell 600 to allow the pins 642 to pass over the protrusions 575, they will obviously feel the change in resistance. The "hand feeling" produced by this change in resistance allows the user to perceive that the pins 642 have been transferred from the second groove 570 to the first groove. A groove 560 reaches the locked state. The protrusion 593 provided in the first groove 560 allows the user to feel the resistance change when the locking shell 600 is unlocked. In addition, the protrusion 593 can prevent the pin 642 from accidentally sliding over and forming an unlocked state. The function of the protrusion 591 is to ensure that the pin 642 can be positioned in the track and will not stay at the dead center of the corner connecting the first groove 560 and the second groove 570 and cannot move. Similarly, the function of the protrusion 592 is also to ensure that the pin 642 can be positioned in the track and will not stay at the dead point of the corner connecting the first groove 560 and the third groove 580 and cannot move. The gaps 576 and 585 formed in the guide groove 550 allow the pin 642 to move in the guide groove 550 only in a counterclockwise direction to lock or unlock.

In addition, as shown in FIG. 20, the connector system 1000 of the present invention can provide the function of optical fiber connector docking, wherein the optical fiber connector (not shown) to be docked uses another set of sleeve 400, locking ring 500 and locking shell 600 Connected to the left end of the socket 700. In order to prevent the forks 421 and 422 of the ferrule 400 from interfering with the forks 422 and 421 of the opposing ferrule 400 when the connector system 1000 provides the optical fiber connector docking function, the fork 422 is designed such that its slit 422a can accommodate the pair The first part of the fork 421a of the fork 421 (please refer to FIG. 21). However, we should understand that the optical fiber connector to be connected can be connected to the left end of the socket 700 by using a sleeve, a locking ring and a locking shell different from the present invention. Please refer to FIG. 22, according to the connector system 1000 of the present invention, the socket 700 can be fixed on a panel 990 with a nut 136. In addition, after the connector system 1000 is assembled, the strap 138 can be tied to the sleeve 400 through the recess 432 to prevent the lock ring 500 from being pulled away from the sleeve 400 backwards. Since the protrusion 541 on the lock ring 500 is positioned above the recess 432, the strap 138 can be prevented from falling off.

Then you can align the notch 839 on the fork 831 with the recess 760 and the protrusion 770 on the socket 700 by touching it with your fingers, and then insert the forks 831 and 832 into the socket 700 and lock the protrusion 641 on the inner wall of the housing 600 They are inserted into the rear part 753 of the groove 750 respectively. Then, the locking shell 600 is rotated to allow the protrusions 641 to slide into the middle section 752 of the groove 750 and reach the front section 751 respectively. A block (not shown) is provided in the socket 700 to restrict the forks 831 and 832 from rotating after being inserted into the socket 700. During the rotation of the locking shell 600, its pins 642 are blocked by the gap 585 and cannot be turned back into the third groove 580, and because the dust cover 800 can only move along the longitudinal direction 191, the pins 642 will be in the second Sliding in the groove 570 and pulling the dust cover 800 toward the locking shell 600, and finally over the protrusion 575 to reach the first groove 560. When the pins 642 are respectively turned into the first groove 560, the dust cover 800 will be inserted into the socket 700 to form a locked state. In addition, during the rotation of the locking shell 600, the protrusions 643 on the inner wall of the locking shell 600 will approach the locking groove 821 from the left side respectively, and finally will cross the retaining wall on the left side of the locking groove 821 and fall into the locking groove 821 respectively.
