Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and in particular to a communication connector, a cable assembly, a composite module and a communication system. Background Art

[0002] Since composite cables combine the functions of optical fiber and wire, they can simultaneously transmit optical signals and power supply. They have been widely used in home networks and campus networks in recent years. Commonly used composite cables include glass optical fiber and copper wire. In actual construction, it is necessary to perform glass fiber fusion splicing and connection operations on the light of the composite cable and the main cable. However, since the core of glass optical fiber is relatively thin and high-precision alignment is required in optical fiber coupling and interconnection, optical fiber fusion splicers are currently commonly used to fuse glass optical fibers. However, optical fiber fusion splicers are expensive, and the fusion quality of glass optical fibers is affected by factors such as the operating level of technicians, the construction environment, and the performance of the fusion splicer, resulting in low overall construction efficiency and high costs. Summary of the invention

[0003] The present application provides a communication connector, a cable assembly, a composite module and a communication system to simplify the construction operation of the composite cable.

[0004] In the first aspect, the present application provides a communication connector. The communication connector includes a housing, a branching module and a clamping piece. Specifically, an input port is provided at one end of the housing, and a plurality of output ports are provided at the other end. The plurality of output ports include at least one first output port and at least one second output port, and each second output port is provided with a plug-in piece. The branching module is located inside the housing. The branching module includes at least one first type branching hole and at least one second type branching hole. The aforementioned at least one first type branching hole connects the input port and the aforementioned at least one first output port and forms a first cable accommodating space, and the first cable accommodating space is used to accommodate the first type of cable. The aforementioned at least one second type branching hole connects the input port and the aforementioned at least one second output port and forms a second cable accommodating space, and the second cable accommodating space is used to accommodate the second type of cable. The plug-in piece extends near one end of the branching module and extends into the second type branching hole. The clamping piece is provided on the housing or the branching module, and the clamping piece is used to limit the first type of cable to the communication connector.

[0005] The communication connector of the present application is used to connect composite cables, which include but are not limited to first type cables and second type cables. The composite cable extends into the communication connector through the input port and is branched through the branching module. After branching, the first type cable can extend out of the communication connector through the corresponding first type branching hole and the first output port. After branching, the second type cable extends into the corresponding second type branching hole and is connected to the plug-in piece that penetrates into the second type branching hole. Therefore, during on-site construction, the composite cable can be directly inserted into the communication connector. And by directly cutting the first type cable so that its end face is flush with the end face of the shell, the construction operation of the composite cable can be simplified and the construction cost can be reduced.

[0006] In some optional technical solutions, the first type of cable may specifically be an optical fiber (also referred to as an optical cable), and the second type of cable may specifically be an electrical cable.

[0007] When specifically set, the number of the first output ports of the shell is not limited. For example, in some optional technical solutions, the above-mentioned multiple output ports may include a first output port and multiple second output ports, the above-mentioned multiple second output ports are arranged along the first direction, and the first output port is arranged on one side of these second output ports. The branching module includes at least one first-type branching hole and multiple second-type branching holes, and the number of the above-mentioned multiple second-type branching holes is the same as the number of the above-mentioned multiple second output ports and is connected one-to-one. One end of the branching module close to the first output port extends into the first output port, and the above-mentioned at least one first-type branching hole is located in the first output port. In this technical solution, the number of first-type branching holes of the branching module can be set according to the number of first-type cables. For example, the first-type branching holes can include one, two, four, six or eight, etc.

[0008] In some other optional technical solutions, the plurality of output ports may include a plurality of first output ports and a plurality of second output ports, the plurality of first output ports and the plurality of second output ports are arranged in parallel and respectively arranged along the first direction. The branching module includes a plurality of first-type branching holes and a plurality of second-type branching holes, the number of the plurality of first-type branching holes is the same as the number of the plurality of first output ports and they are connected one-to-one. The number of the plurality of second-type branching holes is the same as the number of the plurality of second output ports and they are connected one-to-one.

[0009] The above-mentioned clamping member may be arranged on the housing. Specifically, in some optional technical solutions, the housing may be provided with through holes arranged in one-to-one correspondence with the above-mentioned at least one first output port. The through holes penetrate the wall of the housing and communicate with the corresponding first output port. The clamping member is located in the through hole and extends into the first output port along the extension direction of the through hole, so that the first type of cable is limited to the first output port, thereby achieving the fixation of the first type of cable.

[0010] Of course, the clamping member can also be arranged on the branching module. Specifically, in some other optional technical solutions, the at least one first type branching hole is located on the side of the branching module close to the at least one first output port. A receiving groove corresponding to the at least one first type branching hole is provided on the side of the branching module close to the input port. The receiving groove connects the input port and the at least one first type branching hole. In this technical solution, the clamping member can be arranged on the receiving groove. When the first type cable is inserted into the first type branching hole through the receiving groove, the clamping member can clamp the first type cable and limit it in the receiving groove. Alternatively, the clamping member can also be connected to the receiving groove and form a limiting through hole with the receiving groove, so that the first type cable can be limited to the limiting through hole, thereby achieving the fixation of the first type cable.

[0011] In the communication connector of the present application, the shell can be detachably connected to the branching module; or, the shell can also be an integrally formed structure with the branching module.

[0012] In addition, a side of the plug-in piece facing the second type of wire splitting hole may be provided with a sharp tooth structure, which can pierce the insulating outer wall of the second type of cable and be electrically connected to the second type of cable.

[0013] In order to connect with the composite module, the outer surface of the housing may be provided with a clamping portion. When the communication connector is inserted into the composite module, the clamping portion is clamped with the interior of the composite module.

[0014] In the technical solution of the present application, the communication connector may be an RJ type communication connector. Therefore, the communication connector of the present application may utilize the existing RJ type connector housing to further reduce the manufacturing cost.

[0015] In a second aspect, the present application provides a cable assembly. The cable assembly may specifically include a composite cable and a communication connector of the first aspect described above, wherein the communication connector is connected to one end of the composite cable. When assembling the cable assembly, the composite cable extends into the communication connector through the input port and is branched through a branching module. After branching, the first type of cable can extend out of the communication connector through the corresponding first type branching hole and the first output port. After branching, the second type of cable extends into the corresponding second type branching hole and is connected to a plug-in piece that extends deep into the second type branching hole. Therefore, during on-site construction, the composite cable can be directly inserted into the communication connector. And by directly cutting the first type of cable so that its end face is flush with the end face of the shell, the construction operation of the composite cable can be simplified and the construction cost can be reduced.

[0016] Specifically, the composite cable may include at least one first type cable and at least one second type cable. The number of the at least one first type branching hole of the communication connector may be the same as the number of the at least one first type cable and be arranged in one-to-one correspondence, and the number of the at least one second output port of the communication connector may be the same as the number of the at least one second type cable and be arranged in one-to-one correspondence. Each first type cable passes through the input port, the first type branching hole and the first output port in sequence, and the end face of the first type cable is flush with the end face of the first output port, and each second type cable passes through the input port and extends into the second type branching hole.

[0017] In a third aspect, the present application provides a composite module. The composite module includes an opening and a connector port that are relatively arranged. The connector port is used to be plugged into the communication connector of the cable assembly. A plurality of probes are arranged in the connector port, and the number of these probes is the same as the number of plug-in plates of the communication connector. The composite module may also include an optical device, which is arranged in the opening and optically coupled with the first type of cable of the cable assembly. When the communication connector of the first aspect mentioned above is inserted into the composite module, the output port of the communication connector is inserted into the connector port, the optical device is optically coupled with the first type of cable, and the probe abuts and is electrically connected to the plug-in plate, thereby electrically connecting the second type of cable to the power supply device. In this way, the simple plugging of the communication connector and the composite module can realize the optoelectronic connection of the composite cable.

[0018] In the composite module, the optical device may be directly optically coupled to the first type of cable, or the optical device may be optically coupled to the first type of cable through other components.

[0019] For example, in some optional technical solutions, the composite module may further include a first lens group, which is disposed between the opening and the optical device, so that the optical device is optically coupled to the first type of cable through the first lens group.

[0020] In some other optional technical solutions, the composite module may further include a first type cable pigtail, which is arranged between the first lens group and the opening, so that the optical device is optically coupled with the first type cable through the first lens group and the first type cable pigtail.

[0021] In some other optional technical solutions, the composite module may further include a second lens group, which is arranged between the first type of cable pigtail and the opening, so that the optical device is optically coupled with the first type of cable through the first lens group, the first type of cable pigtail and the second lens group.

[0022] In a fourth aspect, the present application provides a communication system, which includes the cable assembly of the second aspect and the composite module of the third aspect, wherein the communication connector of the cable assembly is plugged into the composite module.

Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0077] To facilitate understanding of the communication system provided in the embodiments of the present application, its application scenario is described below. Figure 1 Schematic diagram of a communication system provided in an embodiment of the present application. Figure 1As shown, the communication system 10 of the present application includes a cable assembly 11 and a composite module 12. Among them, the cable assembly 11 includes a composite cable 20 and a communication connector 30, and the communication connector 30 is connected to the end of the composite cable 20. The composite module 12 is used to plug with the communication connector 30 of the cable assembly 11. In practical applications, the composite module 12 can be specifically set in a communication device. When it is necessary to simultaneously realize the signal connection and power supply connection between two or more communication devices, the communication connector 30 of the cable assembly 11 is connected to the composite module 12 of the communication device, thereby realizing the optoelectronic interconnection between the communication devices, and can simultaneously realize high-speed optical communication, low-speed electrical communication and power supply functions.

[0078] The communication system 10 can be applied to a home network or a campus network. The communication system 10 can also include a first device A and a second device B. For example, in a home network application scenario, Figure 1 The first device A in the communication system 10 may be a mother router, and the second device B may be a sub-router. Generally, the sub-router is mainly responsible for wireless communication of terminal devices such as mobile phones, tablets, and smart home appliances, and the sub-router completes communication access with the mother router, thereby enabling the terminal device to access the broadband network. Specifically, the communication system 10 may include multiple sub-routers, which cover part of the home, thereby achieving full coverage of the home high-speed wireless network. The mother router can supply power to the sub-router through the composite cable 20, so that the sub-router does not need to use the power cord to obtain electricity from the socket. In the campus network application scenario, the first device A can be an access switch centrally arranged on each floor, and the second device B can be an access point (AP) device placed on the ceiling of the floor. Each AP device is responsible for wireless communication of terminal devices within its coverage range, and the AP device completes communication access with the access switch, thereby enabling the terminal device to access the campus communication network. The access switch can supply power to the AP device through the composite cable 20, so that the AP device does not need to use the power cord to obtain electricity from the socket.

[0079] Figure 2 The cross-sectional structure diagram of a composite cable provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the composite cable 20 includes but is not limited to a first type cable 21 and a second type cable 22. The first type cable 21 can be used to transmit optical signals, and specifically may include optical fibers or optical cables. The second type cable 22 can be used to transmit electrical energy or electrical signals, and specifically may include electrical cables. The outer peripheries of the first type cable 21 and the second type cable 22 are respectively provided with insulating sheaths 23, so that the insulating sheaths 23 can wrap the first type cable 21 and the second type cable 22 and play an effective protective role. The composite cable 20 can solve the communication and power supply problems well, effectively improves the convenience of pipe threading and installation of the composite cable 20, and is also very convenient to deploy.

[0080] At present, the light in the composite cable mainly adopts glass optical fiber. However, the glass optical fiber is thin and the construction is complicated, which makes the overall construction efficiency low and the cost high. Therefore, the present application provides a communication connector, a cable assembly, a composite module and a communication system to simplify the construction operation of the composite cable.

Figure 3 and Figure 4 As shown, the communication connector 30 includes a housing 31, a branching module 32 and a pressing member (not shown in the figure). The first end 31a of the housing 31 is provided with an input port 311, and the second end 31b of the housing 31 is provided with multiple input ports. The multiple input ports include at least one first output port 312 and at least one second output port 313. Each second output port 313 is provided with a plug-in sheet 33.

Figure 4 and Figure 5 As shown, the branching module 32 is accommodated in the accommodating cavity 310. The branching module 32 includes at least one first type branching hole 322 and at least one second type branching hole 323. The first type branching hole 322 can connect the input port 311 and the first output port 312 and form a first cable accommodating space for accommodating a first type of cable. The second type branching hole 323 can connect the input port 311 and the second output port 313 and form a second cable accommodating space for accommodating a second type of cable.

When the communication connector 30 is inserted into the composite module of the communication device, the probe in the composite module contacts the plug-in piece 33 of the communication connector 30 and is electrically connected to the second type of cable 22, realizing the power supply function. The first type of cable 21 can be optically coupled with the optical device of the composite module to realize optical signal transmission.

Therefore, when the communication connector 30 is plugged into the composite module, the first type cable 21 can be directly optically coupled with the optical device without the need for welding operations and setting additional connection points. Therefore, this operation is simple and efficient, and can reduce construction costs.

[0083] In the above embodiment, the plug piece 33 may be provided with a tine structure on one side facing the second type wire splitting hole 323.

Fig.14 and Fig.15As shown, the clamping member 315 can also be provided on the branching module 32. Specifically, the at least one first type branching hole 322 is provided on a side of the branching module 32 close to the at least one first output port 312. A receiving groove 321 corresponding to the at least one first type branching hole 322 is provided on the side of the branching module 32 close to the input port 311.

When the first type cable 21 is inserted into the first type branching hole 322 through the receiving groove 321, the clamping member 315 can compress the first type cable 21 and limit it in the receiving groove 321. Specifically, the pressing member 315 may be a clip fixed in the receiving groove 321, or the pressing member 315 may also be a pressing sheet. When the first type cable 21 passes through the receiving groove 321, the pressing sheet is pressed into the receiving groove 321 from the opening of the receiving groove 321 toward the first type cable 21, thereby limiting the first type cable 21 in the receiving groove 321. Alternatively, the pressing member 315 may be connected to the receiving groove 321. Specifically, the pressing member 315 may cover the receiving groove 321, and form a limiting through hole with the receiving groove 321, so that the first type cable 21 can be limited in the limiting through hole, thereby achieving the fixing of the first type cable 21.

[0089] In the above embodiment, the housing 31 and the branching module 32 are detachably connected, which facilitates the wiring operation of the composite cable 20 during construction. Specifically, the branching module 32 can be snap-fitted with the housing 31, or the branching module 32 can be fixed in the housing 31 by interference fit. Of course, in other embodiments, the housing 31 and the branching module 32 can also be an integrally formed structure, so that they can be integrally formed using the same mold to reduce the manufacturing cost.

[0090] In addition, in order to limit the composite cable 20 in the accommodating chamber 310, a pressing piece 317 is provided on the inner wall of the accommodating chamber 310, and the pressing piece 317 is provided near the first end 31a. When the composite cable 20 is connected to the communication connector 30, the pressing piece 317 can abut against the composite cable 20, thereby limiting the composite cable 20 relative to the housing 31.

[0091] The communication connector 30 adopts an RJ type communication connector. In actual construction, it can realize the optical-electrical interconnection of the composite cable 20 and retain the existing RJ type network port and RJ type opening, thereby providing flexibility in communication connection between communication devices and reducing production costs. In specific operation, the composite cable 20 is inserted into the housing 31 after the wiring is completed through the branching module 32. The composite cable 20 and the communication connector 30 use a clamping part 314 that is consistent with the traditional RJ type connector. The clamping part 314 can be a crimping head (such as Fig.12), or it may be a dovetail clip assembled on the surface of the housing 31. After the branching module 32 is fixed to the housing 31, the plug-in piece 33 can be pressed into and pierced through the second type cable 22 using a network cable pliers to achieve electrical contact between the second type cable 22 and the plug-in piece 33. Subsequently, the first type cable 21 extending out of the communication connector 30 is cut so that the end face of the first type cable 21 is roughly flush with the end of the communication connector 30. The communication connector 30 is pressed as a whole on sandpaper for hand polishing to make the cut end face flat to reduce coupling loss.

[0092] Fig.16 A schematic diagram of the structure of a composite module provided in an embodiment of the present application. Fig.16 As shown, in some embodiments, the composite module 12 can be specifically in the form of a sleeve 121. The composite module 12 includes an opening 1211 and a connector port 1212 that are arranged opposite to each other, and the connector port 1212 is used to plug with the communication connector 30 of the cable assembly 11. A plurality of probes 1213 are arranged in the connector port 1212, and the number of the plurality of probes 1213 is the same as the number of the plug-in plates 33 of the communication connector 30. The probes 1213 can also be electrically connected to an external power supply device. The composite module 12 also includes an optical device 122, which is arranged in the opening 1211 and optically coupled with the first type cable 21 of the cable assembly 11 through the opening 1211. When the communication connector 30 of the above embodiment is inserted into the composite module 12 of the communication device 10, the second end 31b of the housing 31 of the communication connector 30 is inserted into the connector port 1212, and the probe 1213 abuts against and is electrically connected to the plug-in plate 33, so that the second type cable 22 is electrically connected to the external power supply device. The optical device 122 is optically coupled with the first type cable 21. In this way, the plugging of the communication connector 30 and the composite module 12 can realize the optoelectronic connection of the composite cable 20 .

[0093] like Fig.16 As shown, in the composite module 12, the optical device 122 can be directly optically coupled to the first type cable 21. Alternatively, the optical device 122 can be optically coupled to the first type cable 21 through other components.

[0094] Fig.17 Another structural diagram of the composite module provided in the embodiment of the present application. Fig.17 As shown, in some embodiments, the composite module 12 may further include a first lens group 123 , which is disposed between the opening 1211 and the optical device 122 , so that the optical device 122 is optically coupled to the first type cable 21 through the first lens group 123 . Fig.18 Another structural diagram of the composite module provided in the embodiment of the present application. Fig.18As shown, in some other embodiments, the composite module 12 may further include a first type cable pigtail 124, which is disposed between the first lens group 123 and the opening 1211, so that the optical device 122 is optically coupled with the first type cable 21 through the first lens group 123 and the first type cable pigtail 124. Fig.19 Another structural diagram of the composite module provided in the embodiment of the present application. Fig.19 As shown, in some other embodiments, the composite module 12 may further include a second lens group 125, which is disposed between the first type cable pigtail 124 and the opening 1211, so that the optical device 122 is optically coupled with the first type cable 21 through the first lens group 123, the first type cable pigtail 124 and the second lens group 125.

[0095] When the communication connector 30 is an RJ type communication connector, the composite module 12 can accordingly adopt an RJ type network port, which can retain the low-speed communication and power supply functions of the existing RJ network port, making the composite module 12 more compatible and fault-tolerant, and reducing the manufacturing cost. Figure 8 As shown, in the present application, the end face of the first output port 312 of the housing 31 may protrude from the second end 31b, so that a standard RJ type communication connector may be used as the housing 31 of the communication connector 30 of the present application. At this time, the end of the first type cable 21 facing the composite module 12 is flush with the end face of the first output port 312. Of course, the end face of the first output port 312 of the housing 31 may also be flush with the surface of one side of the second end 31b facing the composite module 12, so that the housing 31 forms a non-standard RJ type communication connector, which can be applied to a non-standard RJ type network port.
