Description

Technical Field

[0001] This disclosure relates to the field of optoelectronic communication technology, and in particular to a right-angle active connector. Background Technology

[0002] Active electrical connectors typically refer to connectors that integrate an optoelectronic / electro-optical conversion module into a traditional electrical connector and transmit signals via optical fiber. They possess the connection reliability of electrical connectors, eliminate the problem of end-face contamination during insertion and removal, and retain the advantages of fiber optic transmission, such as high bandwidth, low loss, lightweight design, and resistance to electromagnetic interference. Furthermore, no additional optoelectronic / electro-optical conversion circuitry is required within the connected device. Therefore, they are widely used in communication equipment in aerospace, missile-borne, airborne, shipborne, and vehicle-mounted applications.

[0003] Currently, circular electrical connectors exist, such as the J599E series. Their main features include a three-threaded quick-locking and disengagement mechanism, a five-key structure for blind mating and preventing incorrect mating, and waterproof / vapor-proof connection capabilities. Integrating an optoelectronic / electro-optical conversion module into this series of connectors presents the following design challenges:

[0004] 1. The pin contacts in the electrical connector are used to transmit electrical signals, and it is necessary to electrically interconnect the high-density distributed pin contacts with the photoelectric / electro-optical conversion module;

[0005] 2. Electrical connectors have a certain length along their axis, and optical cables require a large amount of space when turning. Specific communication equipment generally has strict requirements for the axial installation space of connector products, especially in environments with limited installation space. Therefore, the axial dimension of active electrical connectors should be as short as possible.

[0006] 3. Electrical connectors are also used in specific environments, some of which are quite harsh. While considering reducing the axial dimensions, it is also necessary to take into account the heat dissipation design, sealing design, and electromagnetic compatibility design of the active electrical connector optical cable assembly. Utility Model Content

[0007] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a right-angle active connector that can be easily connected to power in space-constrained applications and ensures that the internal fiber optic cable transfer is effectively shortened.

[0008] The purpose of this disclosure is achieved through the following technical solution:

[0009] A right-angle active connector includes a passive plug, a housing, a printed circuit board assembly, and an adapter optical cable. The housing has a power connection port and a receiving cavity. The power connection port communicates with the receiving cavity. The printed circuit board assembly and the adapter optical cable are both located within the receiving cavity. A portion of the passive plug is located within the power connection port, and the passive plug is connected to the housing. The passive plug has a power connection pin group. A preset angle is formed between the passive plug and the housing to reduce the axial length of the passive plug.

[0010] The printed circuit board assembly includes a printed circuit board body and an optoelectronic / electro-optical communication component. The optoelectronic / electro-optical communication component includes a lens and an optoelectronic / electro-optical conversion chip set. Both the lens and the optoelectronic / electro-optical conversion chip set are mounted on the printed circuit board body. The power connector pin group is electrically connected to the power supply terminal of the printed circuit board body. The optical transmission end of the adapter cable is connected to the optical interface of the lens. The optical signal transceiver end of the lens is connected to the optocoupler end of the optoelectronic / electro-optical conversion chip set. The power supply terminal of the printed circuit board body is electrically connected to the power receiving terminal of the optoelectronic / electro-optical conversion chip set.

[0011] In one embodiment, the right-angle active connector further includes a heat dissipation cover plate, the housing has a heat dissipation mounting port, the heat dissipation mounting port communicates with the receiving cavity, the heat dissipation cover plate is located inside the heat dissipation mounting port and connected to the housing, and one side of the heat dissipation cover plate abuts against the heat-generating part of the printed circuit board assembly.

[0012] In one embodiment, the printed circuit board assembly further includes a thermal pad and a thermal block. The thermal block is embedded in the printed circuit board body, the photoelectric / electro-optical conversion chip group is disposed on one side of the thermal block, the thermal pad is disposed on the side of the thermal block opposite to the photoelectric / electro-optical conversion chip group, and one side of the heat dissipation cover plate abuts against the thermal pad.

[0013] In one embodiment, the heat dissipation cover is provided with a heat-conducting boss, and the heat-conducting pad abuts against the heat-conducting boss.

[0014] In one embodiment, the housing includes a housing body and a top cover connected together, with a receiving cavity formed between the housing body and the top cover, the power connection port being located on the housing body, and the passive plug being connected to the housing body.

[0015] In one embodiment, the housing further includes a first sealing ring, and the housing body has a first sealing ring groove, the first sealing ring being located in the first sealing ring groove and abutting against the top cover.

[0016] In one embodiment, the right-angle active connector further includes an external wiring optical cable connected to the housing, and the optical connection end of the external wiring optical cable is connected to the optical connection end of the adapter optical cable.

[0017] In one embodiment, the adapter optical cable includes a first connector, an internal optical cable, and a second connector connected in sequence. The optical cable transmission end of the first connector is connected to the optical interface of the lens, and the connection end of the second connector is connected to the optical connection end of the external wiring optical cable.

[0018] In one embodiment, the external optical cable includes a third connector, an external optical cable, and a sheath. The third connector is located within the accommodating cavity and is connected to the external optical cable. The connection end of the third connector is connected to the connection end of the second connector. The sheath wraps around the external optical cable and is connected to the outer shell.

[0019] In one embodiment, the right-angle active connector further includes a connection reinforcement component located within the receiving cavity and connected to the housing, the connection reinforcement component also abutting against the second connector.

[0020] Compared with the prior art, this disclosure has at least the following advantages:

[0021] 1. Because the passive plug and the outer shell form a preset angle, the power connection pin group and the printed circuit board assembly form a certain angle, so that the overall structure is close to "L" shape and the structure is compact, which can facilitate installation and power connection in space-constrained applications.

[0022] 2. This solution uses a lens and an optoelectronic / electro-optical conversion chip. The optoelectronic / electro-optical conversion chip is electrically interconnected with the printed circuit board body by gold wire bonding. Then, it is coupled through the lens, and the optical interface on the lens is connected to the adapter optical cable to lead out the optical signal through the adapter optical cable. At the same time, the lens can rotate the transmission optical path of the adapter optical cable by a certain angle, so that the optical path is parallel to the direction of the printed circuit board, realizing radial fiber output and shortening the length of the internal adapter optical fiber.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0047] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0048] Please see Figure 1 and Figure 2 This is an embodiment of the present invention: a right-angle active connector 10, comprising a passive plug 100, a housing 200, a printed circuit board assembly 300, and an adapter optical cable 400. The housing 200 has a power connection port 201 and a receiving cavity 202, which are connected. The printed circuit board assembly 300 and the adapter optical cable 400 are both located within the receiving cavity 202. A portion of the passive plug 100 is located within the power connection port 201, and the passive plug 100 is connected to the housing 200. The passive plug 100 has a power connection pin group 120. A preset angle is formed between the passive plug 100 and the housing 200 to reduce the axial length of the passive plug 100. Please refer to the accompanying documentation. Figure 3 The printed circuit board assembly 300 includes a printed circuit board body 310 and an optoelectronic / electro-optical communication component 320. The optoelectronic / electro-optical communication component 320 includes a lens 321 and an optoelectronic / electro-optical conversion chip group 322. Both the lens 321 and the optoelectronic / electro-optical conversion chip group 322 are mounted on the printed circuit board body 310. The power connector pin group 120 is electrically connected to the power supply terminal of the printed circuit board body 310. The optical cable transmission end of the adapter optical cable 400 is connected to the optical interface of the lens 321. The optical signal transceiver end of the lens 321 is connected to the optocoupler end of the optoelectronic / electro-optical conversion chip group 322. The power supply terminal of the printed circuit board body 310 is electrically connected to the power receiving terminal of the optoelectronic / electro-optical conversion chip group 322. The optical signal transceiver end of the lens 321 is used to rotate the optical path by a certain angle through its own optical characteristics, so that the optoelectronic / electro-optical conversion chip group 322 receives the optical path and performs optocoupler to convert it into an electrical signal output.

[0049] In this embodiment, the passive plug 100 includes a connector body 110 and a power-connecting pin assembly 120. The connector body 110 has a power-connecting mounting channel 111. The power-connecting pin assembly 120 is located in the mounting slot and connected to the power-connecting pin assembly 120. The power-connecting pin assembly 120 and the power-connecting mounting channel 111 are arranged coaxially. One end of the power-connecting pin assembly 120 is used to connect to a power socket, and the other end is electrically connected to the power terminal of the printed circuit board assembly 300. Since the passive plug 100 and the housing 200 form a preset angle, the power-connecting pin assembly 120 and the printed circuit board assembly 300 form a preset angle, making the overall structure approximately "L"-shaped. That is, the overall length of the passive plug 100 along its axial direction is shorter. Specifically, the preset angle is 90°, making the overall structure "L"-shaped, and thus making the structural length of the power-connecting pin assembly 120 along its extension direction shorter. The power connector group 120 has multiple power connectors, and the multiple power connectors are electrically connected to the power supply terminal of the printed circuit board assembly 300.

[0050] In the above embodiments, since the passive plug 100 and the outer shell 200 form a preset angle, the power connection pin group 120 and the printed circuit board assembly 300 form a certain angle, so that the overall structure is close to "L" shape and compact. It can be conveniently installed and connected to power in space-constrained applications. In addition, this solution uses a lens 321 and an optoelectronic / electro-optical conversion chip group 322. The optoelectronic / electro-optical conversion chip group 322 is electrically interconnected with the printed circuit board body 310 by gold wire bonding. Then, it is coupled through the lens 321. The optical interface on the lens 321 is connected to the adapter optical cable 400 to lead out the optical signal through the adapter optical cable 400. At the same time, the lens 321 can rotate the transmission optical path of the adapter optical cable 400 by a certain angle, so that the optical path is parallel to the direction of the printed circuit board 310, realizing radial fiber output and shortening the length of the internal adapter optical fiber.

[0051] In one embodiment, such as Figure 2 and Figure 9 As shown, the right-angle active connector 10 also includes a heat dissipation cover 500. The housing 200 has a heat dissipation mounting port 203, which communicates with the receiving cavity 202. The heat dissipation cover 500 is located inside the heat dissipation mounting port 203 and is connected to the housing 200. One side of the heat dissipation cover 500 abuts against the heat-generating part of the printed circuit board assembly 300. Thus, the heat dissipation cover 500 is positioned to contact the heat-generating part of the printed circuit board assembly 300, which allows the heat generated by the printed circuit board assembly 300 to be dissipated through the heat dissipation cover 500, ensuring the normal operation of the connector as a whole.

[0052] Furthermore, combined Figure 2 , Figure 3 and Figure 4As shown, the printed circuit board assembly 300 also includes a thermal pad 330 and a thermal block 340. The thermal block 340 is embedded in the printed circuit board body 310. The photoelectric / electro-optical conversion chip group 322 is disposed on one side of the thermal block 340, and the thermal pad 330 is disposed on the side of the thermal block 340 facing away from the photoelectric / electro-optical conversion chip group 322. One side of the heat dissipation cover plate 500 abuts against the thermal pad 330. It can be understood that when the connector is working, the printed circuit board assembly 300 is powered on, and the photoelectric / electro-optical communication component 320 operates to transmit data in the form of photoelectric / electro-optical conversion. During this process, the photoelectric / electro-optical conversion chip group 322 generates heat. Due to the high-speed heat transfer characteristic of the thermal block 340, this heat can be quickly transferred from one side of the printed circuit board body 310 to the other side, and finally dissipated from the thermal pad 330 through the heat dissipation cover plate 500, thus achieving a good heat dissipation effect.

[0053] In another embodiment, the photoelectric / electro-optical conversion chip group 322, the heat-conducting block 340, and the heat-conducting pad 330 constitute the heat-generating part of the printed circuit board assembly 300.

[0054] Furthermore, the heatsink 340 is copper-embedded, which has good thermal conductivity. The optoelectronic / electro-optical conversion chip group 322 uses PHXR8104 and PHXT8104 chips to support data transmission and reception. The thermal pad 330 uses silicone grease to give it good thermal conductivity.

[0055] In another embodiment, there are two sets of optoelectronic / electro-optical communication components 320. Both sets of optoelectronic / electro-optical communication components 320 are used for optoelectronic / electro-optical signal communication. Furthermore, the two sets of optoelectronic / electro-optical communication components 320 are powered independently and serve as backups for each other. Even if one set of optoelectronic / electro-optical communication components 320 is damaged, the other set of optoelectronic / electro-optical communication components 320 can still be used to ensure the overall communication stability of the connector.

[0056] Furthermore, the heat sink 500 is connected to the housing 200 by screws, which makes the heat sink 500 removable and installable. When the thermal pad 330 needs to be replaced, the screws can be loosened to remove the heat sink 500, at which point the thermal pad 330 is exposed. Then, a new thermal pad 330 is replaced, and finally the screws are tightened to fix the heat sink 500. This makes it convenient and simple to replace the thermal pad 330, and the thermal pad 330 can be replaced without removing the entire housing 200.

[0057] like Figure 2 As shown, in one embodiment, the heat dissipation cover 500 is provided with a heat-conducting protrusion 501, combined with... Figure 4As shown, the thermal pad 330 abuts against the thermal protrusion 501, allowing the heat generated by the photoelectric / electro-optical conversion chip 322 to pass sequentially through the thermal block 340, the thermal pad 330, and the thermal protrusion 501, ultimately dissipating from the heat sink 500 itself, thus achieving a heat dissipation effect and preventing the temperature of the photoelectric / electro-optical conversion chip 322 from continuing to rise. Furthermore, the thermal pad 330 is press-fitted against the thermal protrusion 501 and the thermal block 340.

[0058] like Figure 2 As shown, in one embodiment, the housing 200 includes a housing body 210 and a top cover 220 connected to each other. A receiving cavity 202 is formed between the housing body 210 and the top cover 220. An electrical connection port 201 is provided on the housing body 210, and a passive plug 100 is connected to the housing body 210. In this embodiment, the housing body 210 and the top cover 220, as well as the passive plug 100 and the housing body 210, are fixedly connected by screws. Further, combined with Figure 9 As shown, the outer casing 200 also includes a first sealing ring 230. The outer casing 200 has a first sealing ring groove 204, and the first sealing ring 230 is located in the first sealing ring groove 204 and abuts against the top cover 220. Thus, after the top cover 220 and the outer casing body 210 are fixed with screws, the first sealing ring 230 is press-fitted against the top cover 220 and the outer casing body 210 respectively, further preventing external dust or moisture from entering the interior of the structure through the first sealing ring groove 204.

[0059] In another embodiment, the heat dissipation mounting port 203 is provided on the housing body 210, and the heat dissipation cover 500 is connected to the housing body 210. Specifically, the housing body 210 and the heat dissipation cover 500 are fixedly connected by screws, so that the housing body 210 and the heat dissipation cover 500 can be detachably connected by screws in order to maintain the printed circuit board assembly 300.

[0060] Furthermore, such as Figure 9 and Figure 10 As shown, the housing 200 also includes a second sealing ring 240, and the housing 200 also has a second sealing ring groove 205. The second sealing ring 240 is located in the second sealing ring groove 205 and abuts against the heat dissipation cover plate 500. Thus, after the heat dissipation cover plate 500 and the housing body 210 are fixed with screws, the second sealing ring 240 is press-fitted against both the heat dissipation cover plate 500 and the housing body 210, further preventing external dust or moisture from entering the structure through the second sealing ring groove 205. Furthermore, the sealing ring reduces the probability of moisture or dust entering the internal structure of the connector, ensuring the sealing and electromagnetic compatibility of the connection point. Even when the active connector is used in harsh environments such as sandstorm areas or high humidity areas, it can ensure stable operation of the product.

[0061] like Figure 2 , Figure 5 and Figure 6 As shown, in one embodiment, the right-angle active connector 10 further includes an external optical cable 600, which is connected to the housing 200, and the optical connection end of the external optical cable 600 is connected to the optical connection end of the adapter optical cable 400. Further, the adapter optical cable 400 includes a first connector 410, an internal optical cable 420, and a second connector 430 connected in sequence. The optical transmission end of the first connector 410 is mated with the optical interface of the lens 321, and the connection end of the second connector 430 is connected to the optical connection end of the external optical cable 600. Further, the external optical cable 600 includes a third connector 610, an external optical cable 620, and a sheath 630. The third connector 610 is located within the accommodating cavity 202, is connected to the external optical cable 620, and the connection end of the third connector 610 is connected to the connection end of the second connector 430. The sheath 630 wraps around the external optical cable 620 and is connected to the housing 200.

[0062] In this embodiment, combined with Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the optical transmission end of the first connector 410 is connected to the optical interface of the lens 321. It can be understood that when the active connector is working, since the first connector 410 is connected to the optical interface of the lens 321, the second connector 430 is connected to the third connector 610. The adapter optical cable 400, which consists of the first connector 410, the internal optical cable 420 and the second connector 430, is used to lead the input / output signals of the photoelectric / electro-optical conversion chip group 322 out from the second connector 430 for data communication.

[0063] Furthermore, combined Figure 3 and Figure 5 As shown, the first connector 410 has a first guide hole, and the lens 321 has a first guide pin 3211. The first guide pin 3211 is located in the first guide hole, wherein the first guide pin 3211 serves a guiding function to ensure precise mating between the first connector 410 and the lens 321. In another embodiment, as... Figure 5 and Figure 6 As shown, the second connector 430 has a second guide pin 431, and the third connector 610 has a second guide hole. The second guide pin 431 is located in the second guide hole. The second guide pin 431 plays a guiding role, which can ensure accurate docking between the adapter optical cable 400 and the external wiring optical cable 600.

[0064] It is understandable that when the external optical cable 600 uses a sheath 630, it can effectively protect the external optical cable 620 and prevent structural damage caused by compression or bending. Furthermore, as... Figure 6 As shown, the sheath 630 includes a connecting tail 631, a sheath body 632, and an insulating sleeve 633. The connecting tail 631 is connected to the outer shell 200, specifically to the outer shell body 210. The sheath body 632 is fitted onto the connecting tail 631 and also partially covers the insulating sleeve 633. The external optical cable 620 is located inside the insulating sleeve 633. Thus, when the insulating sleeve 633 is rotated or stretched, the force acts on the connecting tail 631, which will not affect the external optical cable 620 and thus will not cause damage to the external cable.

[0065] like Figure 2 and Figure 7 As shown, in one embodiment, the right-angle active connector 10 further includes a connection reinforcement component 700, which is located within the accommodating cavity 202 and connected to the housing 200. The connection reinforcement component 700 also abuts against the second connector 430 to ensure a stable connection between the second connector 430 and the third connector 610.

[0066] Furthermore, such as Figure 7 , Figure 8 and Figure 12 As shown, the connecting reinforcement assembly 700 includes a fixing member 710, a spring 720, and a slider 730. The fixing member 710 is connected to the outer shell 200, specifically, the fixing member 710 is connected to the outer shell body 210. The fixing member 710 has a limiting groove 7101. The spring 720 is located in the limiting groove 7101, and both ends of the spring 720 abut against the bottom of the limiting groove 7101 and the slider 730, respectively. The slider 730 also abuts against the second connector 430. It can be understood that the spring 720 has a certain elasticity, which allows it to abut against the bottom of the limiting groove 7101 and the slider 730, thereby acting on the slider 730. Under the action of the spring 720, the slider 730 abuts against the second connector 430 to ensure the stability of the second connector 430 and the third connector 610 and prevent them from falling off under the action of external force.

[0067] Furthermore, combined Figure 7 , Figure 8 and Figure 12 As shown, the slider 730 has a limiting protrusion 731, and the fixing member 710 has a limiting channel 7102. The limiting protrusion 731 is located in the limiting channel 7102 and abuts against the second connector 430. Thus, the setting of the limiting protrusion 731 ensures that the slider 730 itself will not detach from the limiting groove 7101, thus ensuring the stability of the second connector 430 and the third connector 610.

[0068] Furthermore, such as Figure 8 As shown, the fixing member 710 includes a fixing plate 711 and a rear plate 712. A limiting channel 7102 is provided on the fixing plate 711, and a limiting groove 7101 is formed between the rear plate 712 and the fixing plate 711. The fixing plate 711 and the rear plate 712 are detachably connected. Specifically, the fixing plate 711 is connected to the rear plate 712 by screws. The fixing plate 711 is also connected to the outer shell body 210, specifically by screws. The two ends of the spring 720 abut against the rear plate 712 and the slider 73, respectively. 0. Thus, after prolonged use of spring 720 and slider 730, their service life is shortened. The connecting reinforcement assembly 700 can be removed by loosening the screws with a tool, and then the back plate 712 can be removed by loosening another screw, thereby taking out spring 720 and slider 730 and replacing them with new spring 720 and slider 730. Finally, the back plate 712 is fixed by tightening the screws, and the connecting reinforcement assembly 700 is fixed by tightening the screws again, making the replacement of spring 720 and slider 730 more convenient.

[0069] Furthermore, combining Figure 2 and Figure 7 As shown, the fixing plate 711 and the rear plate 712 are both provided with a clearance notch 7100. Part of the internal optical cable 420 is located in the clearance notch 7100. In this way, when the connecting reinforcement component 700 is installed, the internal optical cable 420 will not be interfered with by the fixing plate 711 and the rear plate 712, which will prevent the internal optical cable 420 from being damaged by compression, thus ensuring the safety and stability of optoelectronic / electro-optical signal communication.

[0070] Furthermore, such as Figure 9 and Figure 11 As shown, the outer shell 200 is provided with a limiting block 206, the second connector 430 has a first notch, and the third connector 610 has a second notch. An abutting groove 20a is formed between the first notch and the second notch. The limiting block 206 abuts against the abutting groove 20a to restrict the movement of the second connector 430 and the third connector 610, thereby ensuring the connection stability of the second connector 430 and the third connector 610, and further ensuring the safety and stability of photoelectric / electro-optical signal communication.

[0071] Compared with the prior art, this disclosure includes, but is not limited to, the following advantages:

[0072] 1. Because the passive plug 100 and the housing 200 form a preset angle, the power connection pin group 120 and the printed circuit board assembly 300 form a certain angle, so that the overall structure is close to "L" shape and the structure is compact, which can facilitate installation and power connection in space-constrained applications.

[0073] 2. This solution uses a lens 321 and an optoelectronic / electro-optical conversion chip 322. The optoelectronic / electro-optical conversion chip 322 is electrically interconnected with the printed circuit board body 310 by gold wire bonding. It is then coupled through the lens 321, and the optical interface on the lens 321 is connected to the adapter optical cable 400 to lead out the optical signal through the adapter optical cable 400. At the same time, the lens 321 can rotate the transmission optical path of the adapter optical cable 400 by a certain angle, so that the optical path is parallel to the direction of the printed circuit board 310, realizing radial fiber output and shortening the length of the internal adapter optical fiber.

[0074] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
