Description

Technical Field

[0001] The utility model relates to the technical field of connectors, specifically a MT vertical light steering module. Background Art

[0002] With the development of electronic equipment technology, radar and other electronic equipment are composed of more and more components, and their chassis are getting smaller and smaller. In actual use, the rectangular integrated connector on the back panel inside the chassis will need to bend the optical fiber at the tail of the contact for wiring. Excessive bending of the optical fiber will greatly increase the light loss during light transmission. Due to the limitation of the bending radius of the optical fiber, sufficient space needs to be left for the bending of the optical fiber, which limits the further reduction of the chassis volume and cannot meet the development requirements of electronic equipment.

[0003] In response to the problem of fiber optic wiring bending, the "On-board Fiber Vertical Interconnection Optical Connector" disclosed in 202010203037.X, although this connector can be vertically interconnected, its steering structure needs to be plugged with the MT contact protruding from the end face of the plug shell. Therefore, the order of guiding the plug-in is the MT guide pin I of the plug-the guide pin II of the socket shell-the socket shell. The MT contact of the plug is used as the first-level guide, which is very likely to cause damage to the end face of the plug during use. And. The steering floating structure uses a spring to directly press the steering contact, which will cause the steering lens to bounce up and come out of the MT, destroying the optical path alignment accuracy and dramatically increasing the link loss. At the same time, the vertical light steering structure is not a modular structure and is limited by the connection of the site and other components. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an MT vertical light steering module, which reduces the space required for optical fiber to convert the light output direction by 90 degrees, and prevents the MT contact of the docking plug from being damaged by collision through a special structure of the transfer contact.

[0005] In order to achieve the above technical purpose, the adopted technical solution is: an MT vertical light steering module, provided with a module housing, and also including a transfer contact and a steering contact arranged in the module housing, a fastener for fixing the installation module is provided on the module housing, a first installation cavity for installing the steering contact and a second installation cavity for installing the transfer contact are provided in the module housing, the first installation cavity and the second installation cavity are vertically arranged, one end of the first installation cavity passes through the outer surface of the module housing for connecting the optical fiber, the other end of the first installation cavity is connected to one end of the second installation cavity, and the other end of the second installation cavity passes through the outer surface of the module housing;

[0006] The transfer contact is composed of a first MT pin and a second MT pin which are butt-connected, optical fibers with coatings stripped are inserted into the first MT pin and the second MT pin, and the second MT pin extends out of the second installation cavity to be interconnected with a matching plug;

[0007] The steering contact piece is composed of a fiber array module for fixing the inserted optical fiber and a steering lens connected to the fiber array module. The steering lens vertically steers the light spot emitted by the optical fiber and then vertically interconnects with the first MT pin of the transfer contact piece.

[0008] The module housing is composed of a pressing plate and a base fixed as one body, a mounting groove for assembling a steering contact is provided on the surface of the base in contact with the pressing plate as a first mounting cavity, and a second mounting cavity for assembling a switching contact is provided on the pressing plate.

[0009] The optical fiber array module is a FA module or a MT pin module.

[0010] The height of the second MT pin in the plugging direction is smaller than the height of the first MT pin.

[0011] A positioning column for guiding and plugging in and matching with the positioning hole at the installation position is provided on the end surface of the module housing.

[0012] The first MT pin and the second MT pin are provided with guide pin holes which are connected after docking. A matching first guide pin is inserted into the guide pin hole for docking and fixing the first MT pin and the second MT pin. The part of the first guide pin exposed outside the hole is used to cooperate with the front guide pin hole of the adapter plug.

[0013] A second guide pin is arranged on the end surface of the first MT pin, and a mounting hole for the second guide pin to be inserted in cooperation is arranged on the steering contact piece.

[0014] One end of the second guide pin is installed in the guide pin hole that is connected to the first MT pin and the second MT pin after being connected.

[0015] A hollow boss is provided on the module housing, the cavity of the hollow boss is connected to the second installation cavity, and the end surface of the hollow boss is lower than the end surface position of the second MT pin, which is used to protect the connection position of the first MT pin and the second MT pin.

[0016] The fastener is selected from one of screws, bolts, threaded rods or floating fixing mechanisms. The floating fixing mechanism includes a limit screw, a spring and a fixing hole that passes through the module shell and is arranged in the same direction as the second installation cavity. The fixing hole is composed of a large-diameter hole and a small-diameter hole that are connected. The small-diameter hole is arranged in the direction corresponding to the plug-in connection of the plug. The spring is installed in the large-diameter hole. The rod of the limit screw is inserted into the spring and passes through the small-diameter hole for fixing in a threaded hole that matches the installation position.

[0017] A nut is sleeved on the rod portion of the limit screw extending out of the small-diameter hole, so as to prevent the floating fixing mechanism from falling off when the module is disassembled from the installation position.

[0018] The beneficial effects of the utility model are:

[0019] 1. The module is an integrated design, easy to use, and can achieve a 90° turn of the optical path. Installing a transfer contact above the turn lens can raise the light-emitting surface of the socket end, so that the MT contact surface of the socket and the plug returns to the normal design level, avoiding the problem that the MT pin has to protrude from the end face of the plug shell to contact the light-emitting surface of the socket when designing the plug end structure, reducing plug-in damage and improving product reliability. In addition, the transfer contact consists of two MT pins, with a simple structure, no need to re-open the mold, and low cost.

[0020] 2. The module housing is made into an assembleable pressure plate and base structure, both of which have corresponding installation cavities for installing steering contacts and transfer contacts, which makes assembly intuitive and replacement convenient.

[0021] 3. The fiber array module can be selected from FA module or MT pin module. The MT pin module has its own guide pin hole, which is more convenient for positioning. The FA module has more varieties and types than the MT core number variety and a wider range of applications. It can be reasonably selected according to different usage scenarios.

[0022] 4. Use a second MT pin with a height lower than the first MT pin. On the premise that the two MT pins can be connected to form a transfer contact, the connection height is sufficient, the model height can be reduced, the fiber insertion length is short, and fiber breakage can be avoided.

[0023] 5. Positioning posts are set on the module housing to first determine the plug-in position and provide primary plug-in guidance.

[0024] 6. Insert the first guide pin into the guide pin hole on the transfer contact, which can connect and fix the first MT pin and the second MT pin, and can also dock with the guide pin hole of the MT pin at the front end of the plug to play a role of fixing and guiding. It can be combined with the positioning column to achieve primary and secondary dual positioning and guiding to prevent the MT pins from bumping.

[0025] 7. The second guide pin provided on the transfer contact can cooperate with the mounting hole on the steering contact to achieve docking guidance and positioning of the transfer contact and the steering contact. The guide pin hole provided by the MT pin can be fully utilized, and no additional mold is required. The original structure can be reasonably utilized to achieve the installation of the second guide pin.

[0026] 8. Adding a hollow boss on the module housing can protect the connections and reduce the size of the module. When the socket housing is docked, the hollow boss can be inserted into the socket housing to ensure the height of the light-emitting surface of the socket end.

[0027] 9. The fasteners have various structures. When a floating fixing mechanism is used, when the plug and the socket are docked, the entire module moves downward, and the compression of the spring ensures that the MT pin is blocked during the movement.

[0028] 10. A nut is sleeved on the rod of the limit screw to fix the position of the limit screw. When the entire module is removed from the socket housing, the floating fixing mechanism will not fall off and can also play a role in fixing the pressure plate and the base.

[0048] like Fig.12 , Fig.13 As shown, a MT vertical light steering module can be installed on a connector. In the connector, a rectangular integrated socket 12 is docked with a rectangular integrated plug 13. The module is used to dock with an MT plug 14. The plug mainly includes MT pins, etc., which is a well-known technology. The end of the plug used for plugging is the front end. The module has an independent module housing 11, which can be installed on a socket housing 15. The socket housing 15 is provided with a socket for module installation. This module can be installed in a rectangular integrated connector with a dedicated MT hole position. While realizing multi-channel optical signal connection, it realizes vertical transfer of high-density optical signals to another MT, solves the problem that optical fiber bending easily increases loss or even breaks, and maximizes the use of the connector installation space.

[0049] like Figure 1 , Figure 2 As shown, the module includes a transfer contact 5 and a steering contact 6 arranged in a module housing 11, and a fastener 16 for fixing and installing the module is provided on the module housing 11, which can be fixed to the socket housing 15 through the fastener 16, and the fastener 16 supports the module during positioning and plugging. A first installation cavity 17 for installing the steering contact 6 and a second installation cavity 18 for installing the transfer contact 5 are provided in the module housing 11. The first installation cavity 17 cooperates with the steering contact 6 to prevent the steering contact 6 from shaking in the module, and the second installation cavity 18 cooperates with the transfer contact 5 to prevent the transfer contact 5 from shaking in the module. The first installation cavity 17 and the second installation cavity 18 are vertically arranged, one end of the first installation cavity 17 passes through the outer surface of the module housing 11 for connecting the optical fiber 7, the other end of the first installation cavity 17 is connected to one end of the second installation cavity 18, and the other end of the second installation cavity 18 passes through the outer surface of the module housing 11, and the surface passed through by the second installation cavity 18 is the end face for plugging with the plug.

[0050] like Figure 3 , Fig.14As shown, the transfer contact 5 is composed of a first MT pin 19 and a second MT pin 20 that are butt-connected. Optical fibers with coatings stripped are inserted into the first MT pin 19 and the second MT pin 20. The second MT pin 20 extends out of the second mounting cavity 18 for interconnection with a matching plug. The transfer contact 5 is used to connect with the steering contact 6 to raise the light-emitting surface of the socket end, so that the MT pin of the MT plug 14 can be located in the plug housing without exposing the end face of the plug. The plug is guided by the plug housing to connect with the second MT pin, making the docking structure more reliable.

[0051] The height of the second MT pin 20 in the plugging direction is less than that of the first MT pin 19, which can reduce the height of the module without affecting the plugging with the MT plug. If lower MT pins are used, the height of the formed transfer contact 5 is insufficient.

[0052] The first MT pin 19 and the second MT pin 20 can be fixed together by bonding, or fixedly connected by using a guide pin through a guide pin hole provided therein, and the fixation can be achieved by inserting the guide pin into the guide pin hole. Different connection structures can be reasonably selected according to the needs of the scene.

[0053] The specific implementation method of using guide pins for fixed connection is as follows: the first MT pin 19 and the second MT pin 20 are provided with guide pin holes that are connected after docking, and the first guide pins 21 adapted are inserted into the guide pin holes for docking and fixing the first MT pin 19 and the second MT pin 20. The portion of the first guide pin 21 exposed outside the hole (exposed from the front end of the second MT pin 20) is used to cooperate with the front end guide pin hole of the adapted MT plug 14, which has the function of guiding the plugging, and can also play the role of fixing the transfer contact 5 and the MT plug 14.

[0054] If the first MT pin 19 and the second MT pin 20 are bonded and fixed, the manufacturing process is: the first MT pin 19 and the second MT pin 20 are bonded and fixed. Figure 2 As shown in the figure, the two MT pins are connected and fixed together, and then the optical fiber 30 (as shown in the figure) with the coating stripped is inserted into the two MT pins. Figure 5 As shown), epoxy glue is then injected into the pin window 29, heated and cured, and the end faces on both sides are ground and polished.

[0055] If the first MT pin 19 and the second MT pin 20 are fixed by the first guide pin 21, the manufacturing process is as follows: the first MT pin 19 and the second MT pin 20 are fixed by the first guide pin 21. Figure 4 As shown, only the first guide pin 21 is inserted to fix the two MT pins together, and then the optical fiber (such as Figure 5As shown), then inject epoxy glue at the pin window, heat and cure, push the first guide pin 21 completely into the guide pin hole without exposing it, then grind and polish the end faces on both sides, then push out a part of the first guide pin 21 and glue it.

[0056] like Figure 6 As shown, the steering contact 6 is composed of an optical fiber array module 25 for fixing the inserted optical fiber and a steering lens 26 connected to the optical fiber array module 25. The steering lens 26 and the optical fiber array module 25 can be bonded together or plugged and fixed through corresponding column holes (such as Figure 7 As shown in the figure, the steering lens 26 vertically steers the light spot emitted by the optical fiber and then vertically interconnects it with the first MT pin 19 of the transfer contact 5.

[0057] like Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, the light emitted from the optical fiber in the MT pin of the MT steering contact is transformed into a nearly collimated light beam by the micro-aspheric lens 28 arranged in an array on one side of the steering lens, and then reflected by the 45° inclined surface 31 full reflection mirror to achieve a 90° steering of the light beam. The emitted light is again focused by the array micro-lens on the other side of the steering lens and enters the optical fiber of the transfer contact 5. The above process realizes the 90° steering of the MT optical path. This technology has been disclosed in 202010203037.X and will not be described in detail.

[0058] like Figure 2 , Fig.10 As shown, the module housing 11 is composed of a pressure plate 4 and a base 8 fixed as one. The pressure plate 4 and the base 8 can be fixed as one by fixing screws 3. The two can be detachably fixed to facilitate the installation and removal of the transfer contact 5 and the steering contact 6. A mounting groove for assembling the steering contact 6 is provided on the surface of the base 8 in contact with the pressure plate 4 as a first mounting cavity 17, and a second mounting cavity 18 for assembling the transfer contact 5 is provided on the pressure plate 4. The steering contact 6 is placed in the mounting groove, and the transfer contact 5 is inserted into the second mounting cavity 18. Then the pressure plate 4 and the base 8 are fixed together accordingly to complete the assembly of the module.

[0059] The optical fiber array module 25 is a FA module or a MT ferrule module. The MT ferrule module has a guide pin hole, while the FA module has a variety of core numbers.

[0060] like Figure 1 , Fig.12 , Fig.13 , Fig.14 As shown, a positioning column 1 for guiding and plugging into the positioning hole at the installation position is provided on the end surface of the module housing 11. Figure 2As shown, by opening a through hole in the module housing 11, inserting the positioning column 1, and then plugging it into the positioning hole of the socket housing and the positioning hole of the plug, the module position can be positioned, and the positioning column plays a role in guiding the installation.

[0061] Further, under the above-mentioned various structures, such as Figure 2 , Figure 4 , Figure 7 As shown, a second guide pin 22 is added to the end face of the first MT pin 19, and a mounting hole 23 for the second guide pin 22 to be inserted is provided on the steering contact 6. The second guide pin 22 is aligned and plugged with the mounting hole 23, so that the steering contact 6 and the transfer contact 5 can be guided and plugged, and the misalignment of the two can be prevented.

[0062] like Figure 4 As shown, one end of the second guide pin 22 is installed in the guide pin hole connected to the first MT pin 19 and the second MT pin 20 after docking. The second guide pin 22 is added in the guide pin hole to make full use of the guide pin hole of the MT pin, and no additional mold is required. If the first guide pin 21 also exists, the manufacturing process of the transfer contact is as follows: the first MT pin 19 and the second MT pin 20 are connected to each other. Figure 4 As shown, insert the first guide pin 21 and the second guide pin 22, fix the two MT pins together, and then insert the stripped optical fiber (such as Figure 5 As shown), then inject epoxy glue at the pin window, heat and cure, take out the second guide pin 22, push the first guide pin 21 into the guide pin hole without exposing it, grind and polish the end faces on both sides, and then use the second guide pin 22 to push out a part of the first guide pin 21, and glue the two guide pins together. Similarly, Fig.14 As shown, the lengths of the second guide pin 22 and the first guide pin 21 can be reversed, and the second guide pin 22 is used as a component to fix the first MT pin 19 and the second MT pin 20. The first guide pin 21 is taken out, and the second guide pin 22 is pushed into the guide pin hole to grind and polish the end surfaces on both sides, and then the second guide pin 22 is pushed out by the first guide pin 21, and then the two guide pins are glued together.

[0063] like Figure 1 , Figure 2 As shown, a hollow boss 27 is provided on the module housing 11, and the outer structure of the hollow boss 21 is not restricted. The cavity of the hollow boss 27 is connected to the second mounting cavity 18, and the cavity in the middle boss 27 is used to pass through the transfer contact 5. The end surface of the hollow boss 27 is lower than the end surface position of the second MT pin 20, that is, the second MT pin 20 exceeds the end surface of the hollow boss 27. The hollow boss 21 surrounds the position where the first MT pin 19 and the second MT pin 20 are connected, and is used to protect the connection position of the first MT pin 19 and the second MT pin 20. Fig.12As shown, the hollow boss 27 can be correspondingly inserted into the socket housing, and the MT pin will not directly contact the socket housing. The hollow boss 27 can further play a protective role and be used for limiting and guiding.

[0064] The fastener 16 is selected from a screw, a bolt, a screw rod or a floating fixing mechanism, and uses a threaded structure to achieve a fixed connection between the module and the socket housing 15. A plurality of fasteners 16 can be provided, for example, Figure 1 , Figure 2 As shown, four fasteners 16 are provided, and the floating fixing mechanism can prevent the screws from coming out, and the four corners provide elastic force for greater stability without deflection. Fig.12 As shown, the floating fixing mechanism includes a stop screw 9, a spring 10, and a fixing hole 24 that is set in the same direction as the second installation cavity 18 and passes through the module housing 11. The fixing hole 24 is composed of a large-diameter hole and a small-diameter hole that are connected. The small-diameter hole is set in the direction corresponding to the plug insertion direction. The spring 10 is installed in the large-diameter hole. The rod of the stop screw 9 is inserted into the spring 10 and passes through the small-diameter hole to be fixed in the threaded hole that matches the installation position. A spring 10 is set on each stop screw 9. By passing through the large-diameter hole, the spring passes through the base and presses against the pressure plate of the module (against the bottom surface of the large-diameter hole). When the plug and the socket are connected, the MT presses down against the base of the module, driving the entire module to move downward. The compression of the spring ensures that the MT is not stuck during the movement. At the same time, the spring design also makes the connection elastic force of the MT reach the IEC standard requirement of 18N~22N.

[0065] A nut 2 is sleeved on the rod of the limit screw 9 extending out of the small-diameter hole to prevent the floating fixing mechanism from scattering when the module is disassembled from the installation position. A countersunk hole for placing the nut 2 can be opened on the module housing 11 to ensure that the surface of the module housing 11 is flat.

[0066] The above MT pins all comply with the standard IEC 61754-5-2005 and can be equipped with up to 24 optical fibers.

[0067] The above are only preferred examples of the present invention and are not intended to limit or restrict the present invention. For researchers or technicians in this field, the present invention may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection declared by the present invention.
