Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of MPO ferrules, and in particular to an optoelectronic integrated MPO ferrule assembly and a preparation method thereof. Background Art
[0002] In the prior art, the technical solution of a patent with the publication number CN112987191A and the name of an MPO fiber optic connector proposes an MPO fiber optic patch cord, which includes a locking sleeve, a ferrule, a fiber ribbon, an optical cable, a spring, a spring base, and a sheath. This kind of MPO fiber optic patch cord has the advantages of high density and low insertion loss. In actual production, the number of cores of the fiber ribbon can be changed according to the usage needs, such as 16 cores, 24 cores, 32 cores, etc. However, this kind of MPO fiber optic patch cord can only transmit optical signals.
[0003] The technical solution of a patent with the publication number WO2022037114A1 and the name of a composite module, a composite cable assembly and a control method thereof applied by Huawei proposes a composite structure that can transmit both optical signals and electrical signals, and proposes an application on the MPO connector. For example, without changing the physical structure of the MPO interface, the ribbon fiber on it can be used as a second optical connector, and the two metal guide pins on it can be used as second electrical connectors, so that the MPO optical interface can be used as a first composite connector. This not only simplifies the preparation process of the second optical connector and the second electrical connector (directly using the MPO interface), but also enables the composite module provided by the embodiments of the present application to meet the miniaturization development of switches and APs, and can also be compatible with standard MPO connectors, improving the applicability of the composite module.
[0004] When wiring a line over a long distance, it is usually necessary to use a fiber optic patch cord for in-line connection in the middle, such as using the MPO fiber optic patch cord proposed in the above-mentioned document CN112987191A.
[0005] When the above-mentioned patent solution applied by Huawei is applied to the above-mentioned MPO fiber optic patch cord, only the improvement application of the insertion contact part (that is, the guide pin and the guide hole) is proposed, and the internal structure of the MPO fiber optic patch cord ferrule lacks corresponding design.
[0006] If the power supply line between the MPO connector (specifically the second electrical connector) and the first electrical connector in the patent application solution of Huawei is directly adopted, as proposed in the patent application solution of Huawei: the power supply line can be designed as a circuit board shape, the power supply line can be a cable coated with copper wire, or a flexible circuit board, or at least one of a rigid circuit board, etc.
[0007] This directly leads to the need to additionally add a set of power supply lines inside the ferrule of the MPO fiber optic jumper that originally only transmits optical signals, which will greatly occupy the installation space inside the ferrule or cause the volume of the ferrule to increase correspondingly, being unfavorable for the miniaturization design of the ferrule and requiring further improvement.

Specific implementation mode
[0024] 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 work shall fall within the protection scope of the present invention.
[0025] Please refer to Figures 1-4 , an optoelectronic integrated MPO ferrule assembly, including a mounting base 1 and a ferrule 2. A guiding chute 3 is formed in the mounting base 1 along the plugging direction. The guiding chute 3 has an anti - detachment through - hole 31 opened on the outer side of the mounting base 1 along a first direction that is the same as the insertion direction of the plugging direction.
[0026] The plugging direction is the left - right direction as shown in Figure 1 , the first direction is to the right, that is, the insertion direction is to the right.
[0027] The ferrule 2 is slidably arranged on the guiding chute 3 along the plugging direction. The ferrule 2 has a ferrule front end 21 that penetrates through the anti - detachment through - hole 31 along the first direction. The ferrule 2 has an anti - detachment portion 23 that abuts against the edge of the anti - detachment through - hole 31 to limit the ferrule 2 from detaching from the anti - detachment through - hole 31. The ferrule 2 has a plurality of optical fiber core holes 24 that penetrate through the ferrule front end 21 and the ferrule rear end 22 along the plugging direction.
[0028] A guiding structure is arranged on the ferrule 2, and the guiding structure is used to guide the male ferrule and the female ferrule to cooperate.
[0029] In this embodiment, when the ferrule is used as a male ferrule, the guiding structure includes a guiding pin 41 that penetrates through the front end face of the male ferrule.
[0030] When the ferrule is used as a female ferrule, the guiding structure includes a guiding hole (not shown) formed on the female ferrule for accommodating the conductive guiding pin. When the male ferrule and the female ferrule are cooperating, the guiding pin correspondingly penetrates into the guiding hole, so that the male ferrule and the female ferrule can cooperate along the plugging direction.
[0031] In this embodiment, the guiding structure is a conductive guiding structure 4. When the guiding structures of the male plug core and the female socket core are in guiding contact with each other, it constitutes a conductive contact, that is, an electrical signal can be transmitted from the guiding structure of the male plug core to the guiding structure of the female socket core, or an electrical signal can be transmitted from the guiding structure of the female plug core to the guiding structure of the male plug core.
[0032] In some embodiments, both ends of the guiding pin 41 penetrate out from the front end face and the rear end face of the male plug core respectively. The guiding pin 41 is a conductive guiding pin made of metal.
[0033] In some embodiments, a conductive contact elastic piece is further provided on the guiding hole, so that when the conductive guiding pin is inserted into the guiding hole, conductive contact is achieved through the contact between the conductive contact elastic piece and the guiding pin.
[0034] In some embodiments, when the plug core is a male plug core, a connecting shell (not shown in the figure) is further provided on the mounting base. The connecting shell has a first interface and a second interface at both ends in the plugging and unplugging direction respectively, and the first interface and the second interface are communicated with each other inside the connecting shell.
[0035] The mounting base with the male plug core is located in the first interface, and the mounting base with the female plug core can be correspondingly inserted into the second interface to cooperate with the mounting base with the male plug core, that is, the mating connection between the male connector and the female connector.
[0036] In some embodiments, the connecting shell can lock the mounting base in the corresponding interface.
[0037] In this embodiment, an elastic member is provided in the guiding chute 3. The elastic member is used to apply an elastic force to the plug core 2 to make the plug core 2 slide in the first direction.
[0038] In this embodiment, the elastic member has an elastic deformation direction corresponding to the plugging and unplugging direction in the guiding chute 3. When the plug core 2 moves in the second direction which is the same as the unplugging direction of the plugging and unplugging direction, the elastic member correspondingly undergoes elastic deformation along the plugging and unplugging direction.
[0039] Correspondingly, the elastic member has a front end that cooperates with the plug core 2, and a rear end that cooperates with the inner rear wall of the guiding chute 3 or with a component on the inner wall of the guiding chute 3 that is used to resist the backward movement of the elastic member. When the plug core 2 moves in the second direction which is the same as the unplugging direction of the plugging and unplugging direction, the two jointly apply a force to the front end and the rear end of the elastic member, causing the elastic member to generate elastic deformation or further elastic deformation.
[0040] In this embodiment, the elastic member is a conductive elastic member 5. The front end of the conductive elastic member 5 makes conductive contact with the conductive guiding structure 4, that is, an electrical signal can be transmitted from the elastic member of the male connector (with a male core) to the guiding structure of the male core, and then to the guiding structure of the female socket core; or an electrical signal can be transmitted from the elastic member of the female connector (with a female core) to the guiding structure of the female core, and then to the guiding structure of the male core.
[0041] When the core is a male core, the conductive contact corresponds, for example, to the front end of the conductive elastic member contacting the conductive guiding pin. When the core is a female core, the conductive contact corresponds, for example, to the front end of the conductive elastic member contacting the conductive contact spring piece.
[0042] In this embodiment, an optical cable is provided at the rear end of the mounting base 1. A multi-fiber optical fiber 7 is arranged in the guiding chute 3. One end of the multi-fiber optical fiber 7 is correspondingly arranged on a plurality of optical fiber core holes 24, that is, each optical fiber of the multi-fiber optical fiber is respectively arranged on a different optical fiber core hole; the other end of the multi-fiber optical fiber 7 is correspondingly connected to the optical cable. For example, the optical cable penetrates into the guiding chute from the rear end of the mounting base to be connected to the multi-fiber optical fiber.
[0043] In some embodiments, the multi-fiber optical fiber 7 can be arranged as a ribbon optical fiber.
[0044] In this embodiment, a cable is provided at the rear end of the mounting base 1. The wire core 6 of the cable is electrically connected to the rear end of the conductive elastic member 5. For example, the cable penetrates into the guiding chute from the rear end of the mounting base to electrically connect the wire core to the rear end of the conductive elastic member.
[0045] When the condition of being able to transmit optical signals is met, an electrical signal transmission line is formed through the cable, the conductive elastic member 5, and the conductive guiding structure 4. On the one hand, the MPO core assembly can simultaneously realize the transmission of optical signals and electrical signals, constituting an optoelectronic integrated core assembly. On the other hand, the elastic member for elastically pressing the core and the guiding structure for plugging and guiding are improved to be part of the electrical signal transmission line, without the need to additionally increase too many wiring structures. The internal structure is more concise, the functionality of each component is high, which is beneficial to cost reduction and more conducive to the miniaturized design of the product.
[0046] In some embodiments, the cable and the optical cable are combined on the same cable. For example, the cable and the optical cable are simultaneously coated in the protective outer skin through the same protective outer skin to form a composite cable.
[0047] In some embodiments, the core wire of the cable is a metal core wire to enhance the low tensile strength when there is only an optical cable originally.
[0048] In this embodiment, the conductive elastic member 5 includes a conductive helical compression spring, and the height direction (or the axial direction) of the conductive helical compression spring is the same as the plugging and unplugging direction.
[0049] In some embodiments, the front end of the conductive helical compression spring corresponds to the rear end 22 of the ferrule, and the rear end of the conductive helical compression spring corresponds to the inner rear wall of the guiding chute 3. When the ferrule 2 moves in the second direction, the conductive helical compression spring is jointly pressed and compressed or further pressed and compressed by the rear end 22 of the ferrule and the inner wall of the corresponding guiding chute 3.
[0050] Accordingly, the conductive helical compression spring can apply an elastic force to the rear end 22 of the ferrule.
[0051] In some embodiments, a receiving groove 32 corresponding to the conductive helical compression spring is formed on the inner rear wall of the guiding chute 3 and extends in the second direction. The receiving groove 32 allows for a greater axial receiving length of the conductive helical compression spring. For example, the rear end of the conductive helical compression spring can be received in the receiving groove 32, and the front end of the conductive helical compression spring extends out into the guiding chute 3 in the first direction to cooperate with the rear end 22 of the ferrule.
[0052] In some embodiments, the width of the notch of the receiving groove 32 is smaller than the width of the guiding chute 3, so that a stepped structure is formed between the receiving groove 32 and the guiding chute 3. This stepped structure can limit the sliding stroke of the ferrule 2. When the ferrule 2 slides in the second direction under an external force, the stepped structure can cooperate with the rear end 22 of the ferrule to resist, thereby restricting the ferrule 2 from continuing to slide in the second direction and forming the end point of the sliding in the second direction.
[0053] After the external force is withdrawn, the ferrule 2 slides in the first direction under the elastic force; when sliding in the first direction, the anti-detachment portion 23 can cooperate with the edge of the anti-detachment through-hole 31 to resist, thereby restricting the ferrule 2 from continuing to slide in the first direction and forming the end point of the sliding in the first direction.
[0054] In some embodiments, an intermediate connecting member is further provided between the wire core 6 and the conductive helical compression spring. The intermediate connecting member includes, for example, a first metal washer 33.
[0055] The rear end of the conductive helical compression spring presses against the front end face of the first metal washer 33, and the wire core 6 is welded to the rear end face of the first metal washer 33.
[0056] The receiving groove 32 is provided with a limiting structure for restricting the first metal washer 33 from rotating circumferentially, so as to improve the conductive contact effect between the wire core 6 and the conductive helical compression spring.
[0057] In some embodiments, the limiting structure includes a positioning post 34 connected to the rear end face of the first metal washer 33, and a positioning hole corresponding to the positioning post 34 is provided on the rear inner wall of the receiving groove 32.
[0058] The wire core 6 can be welded to the positioning post 34 on the rear end face of the first metal washer 33.
[0059] In some embodiments, an intermediate connecting member may also be provided between the conductive guiding structure 4 and the conductive helical compression spring. The intermediate connecting member includes, for example, a second metal washer, which is disposed between the front end of the conductive helical compression spring and the conductive guiding needle or the conductive contact elastic piece for contact conductive connection.
[0060] For example, the front end of the conductive helical compression spring presses against the rear end face of the second metal washer, and the front end face of the second metal washer presses against the conductive guiding needle or the conductive contact elastic piece.
[0061] In this embodiment, the conductive helical compression spring is sleeved outside the multi-fiber optical fiber 7, and the internal space of the conductive helical compression spring is applied by the multi-fiber optical fiber 7, which is more conducive to the miniaturized design of the product.
[0062] In this embodiment, a spring guiding member 9 is installed in the guiding chute 3, and the spring guiding member 9 is located between the conductive helical compression spring and the multi-fiber optical fiber 7.
[0063] For example, the spring guiding member 9 is provided in a cylindrical shape. The conductive helical compression spring is sleeved outside the spring guiding member 9, and the spring guiding member 9 is sleeved outside the multi-fiber optical fiber 7, so that the spring guiding member 9 forms a separation between the conductive helical compression spring and the optical fiber. When the conductive helical compression spring performs activities such as being compressed (or reset after compression), on the one hand, the spring guiding member 9 can guide the moving direction of the conductive helical compression spring, and on the other hand, it can protect the multi-fiber optical fiber 7, so that the moving conductive helical compression spring will not cause friction or scratching to the multi-fiber optical fiber within the protection range of the spring guiding member 9.
[0064] In some embodiments, the spring guiding member 9 is a magnetic conductor. The conductive helical compression spring correspondingly forms an inductance coil.
[0065] The magnetic conductor is preferably a magnetic core, or a metal piece with high magnetic permeability such as iron, nickel, or manganese.
[0066] In some embodiments, the spring guiding member 9 guides the conductive helical compression spring, and when the ferrule slides to the end along the first direction, the conductive helical compression spring has a part located outside the spring guiding member 9. For example, the front end of the conductive helical compression spring is located outside the spring guiding member 9, and the rear end of the conductive helical compression spring is sleeved on the spring guiding member 9; when the ferrule 2 slides along the second direction and the conductive helical compression spring is compressed or further compressed, the number of turns of the helical coil of the conductive helical compression spring sleeved on the spring guiding member 9 correspondingly increases, that is, more turns of the coil are sleeved on the magnetic conductor.
[0067] In some embodiments, the outer side of the elastic guide member 9 is insulated. For example, an insulating plastic housing or an insulating rubber housing is sleeved on the outer side of the elastic guide member 9. When the elastic guide member 9 guides the conductive helical compression spring, it can prevent the conductive helical compression spring from directly contacting the spring guide member.
[0068] In some embodiments, the control system (including the control unit) using this ferrule assembly can detect vibration and / or proper insertion during use based on the change in inductance. That is, the compression state of the conductive helical compression spring is detected through the change in inductance, so as to evaluate the position of the ferrule 2 on the guiding chute 3, and then judge whether the ferrule 2 is vibrated during use or whether the ferrule 2 returns to the proper position after insertion.
[0069] Detecting whether the ferrule is vibrated during use can be applied to monitor the use process, so as to judge whether the use environment is calm, and further facilitate technicians to judge the real-time factors or failure reasons of the use scenario.
[0070] In this embodiment, when preparing the optoelectronic combined MPO ferrule assembly, first determine the product dimensions of the first metal washer, ferrule, mounting seat, conductive guiding structure, and second metal washer; then, according to the determined product dimensions, determine the distance L1 from the front end face of the first metal washer to the rear end face of the second metal washer when the anti-detachment part of the ferrule and the edge of the anti-detachment through-hole are in abutting cooperation; then, according to the distance L1, select a conductive helical compression spring whose spring length in the non-compressed and deformed state is greater than or equal to L1; and select a magnetic conductor whose length is less than L1 according to the distance L1, wherein the spring length direction and the length direction of the magnetic conductor are both the same as the plugging direction; finally, assemble the components to obtain the MPO ferrule assembly.

Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description.
