Abstract
Description
Technical Field
[0001] This utility model relates to the field of network communication technology, and in particular to a pluggable communication expansion module and hub. Background Technology
[0002] ARCNET is a local area network (LAN) technology that uses a token bus to manage nodes on the LAN and the data links between them. It has advantages such as time determinism, flexible data transmission methods, high reliability, and support for multiple connection methods, which has led to its widespread application in various fields.
[0003] A hub is a device used to connect multiple network twisted-pair cables or optical fibers to the same physical medium. Existing hubs are usually in the form of integrated packages, that is, with fixed interfaces and communication modules. With the expansion of network communication needs, the configuration of fixed interfaces and communication modules is no longer able to meet the needs of equipment replacement or upgrading, nor can it meet the complex communication connection needs within a region. At this time, multiple hubs need to be configured, which increases the cost of use and the difficulty of wiring. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a pluggable communication expansion module and hub, which has the advantages of being adaptable to different configuration requirements and reducing wiring difficulty.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] According to a first aspect of the present disclosure, a pluggable communication expansion module is provided, comprising:
[0007] The main control board has a plug-in terminal on its first side for electrical connection with the host and a mounting part on its second side.
[0008] A plurality of wiring ports are provided on the mounting section and connected to the main control board. The wiring ports are used to connect to external devices. The wiring ports include one or more combinations of RJ-11 interfaces, fiber optic interfaces and BNC interfaces.
[0009] A locking member is provided on the mounting part for locking with the host. The locking member passes through the mounting part, and a pushing component is sleeved on the locking member, with one end abutting against the mounting part and the other end abutting against the connection area provided on the host. The pushing component is used to generate an elastic force to push the mounting part outward when the locking member is unlocked, so that the plug-in end is disengaged from the host.
[0010] To achieve the above technical solution, the main control board is electrically connected to the host via a plug-in terminal and locked to the host via a mounting part and a locking component. The wiring port is located outside the mounting part, allowing connection to external devices. Since there are various types of wiring ports, configuring multiple sets of these pluggable communication expansion modules on the host can meet different communication connection requirements without the need for multiple types of hubs, thereby reducing usage costs and wiring difficulty. Furthermore, by setting a push component, when different pluggable communication expansion modules need to be disassembled and replaced, the push component generates elastic force during the disassembly of the locking component, pushing the mounting part outward, thereby achieving rapid disassembly of the pluggable communication expansion modules, improving replacement efficiency, and further meeting the configuration requirements of different wiring.
[0011] In some exemplary embodiments, the plug end is provided with conductive plates for electrical connection with the host, and the plug end is provided with a positioning groove in the middle.
[0012] The above technical solution allows for the restriction of the installation direction of pluggable communication expansion modules through the positioning slot, thereby improving installation accuracy.
[0013] In some exemplary embodiments, the pushing component includes:
[0014] A pressure sleeve fitted onto the locking member, the first end of the pressure sleeve being connected to the mounting portion and the second end passing through the mounting portion; and...
[0015] An elastic element is fitted onto the locking member and abuts against the second end of the pressing sleeve. The other end of the elastic element presses against the connection area provided on the main unit, and the compression amount generated by the elastic element when the locking member is locked is at least equal to the width of the insertion end.
[0016] To achieve the above technical solution, in the locked state, the locking component is locked onto the connection area on the host. At this time, the elastic component is compressed to generate elastic force, and the amount of compression is at least equal to the width of the plug-in end. When the locking component is removed, the elastic component will gradually release the elastic force during the process of loosening the locking component. This elastic force can push the plug-in communication expansion module outward through the pressure sleeve, thereby causing the plug-in end to detach from the host, realizing the quick installation and removal of the plug-in communication expansion module.
[0017] In some exemplary embodiments, the first end of the pressure sleeve is provided with an outer pressure ring that expands radially outward, and the second end of the pressure sleeve is provided with an inner pressure ring that contracts radially inward. The inner wall of the inner pressure ring is substantially in contact with the rod portion of the locking member, and the rod portion of the locking member is provided with a smooth rod section that is adapted to the inner pressure ring.
[0018] To achieve the above technical solution, the outer pressure ring facilitates connection with the mounting part, while the inner pressure ring provides sufficient connection or pressure space for the elastic element.
[0019] In some exemplary embodiments, the end of the elastic member is further connected to a receiving ring for pressing against a connection area provided on the host, the inner wall dimension of the receiving ring being larger than the rod dimension of the locking member.
[0020] The above technical solution enables the receiving ring to effectively press against the connection area set on the host, which helps to apply the elastic force more stably to the mounting part.
[0021] In some exemplary embodiments, the main control board is also connected to a status indicator light group, which is disposed on the mounting part and corresponding to each of the wiring ports, for indicating the working status of each of the wiring ports.
[0022] The above technical solution uses status indicator lights to indicate the working status, which helps supervisors to understand the working status in a timely manner and take appropriate action. It also provides timely alerts when a fault occurs.
[0023] According to a second aspect of the present disclosure, a hub is provided, comprising:
[0024] A host computer, which has several slots;
[0025] Multiple sets of pluggable communication expansion modules as described in the first aspect, wherein the pluggable communication expansion modules are plugged into the slots and electrically connected to the host via the plug-in terminals, and the multiple sets of the pluggable communication expansion modules include at least two types of wiring ports; and,
[0026] The power control module located in the host is used to control the power supply to the host.
[0027] The above technical solution can be implemented by configuring multiple communication expansion modules on the host, thereby meeting different wiring requirements without the need to set up multiple types of hubs, thus reducing the cost of use and the difficulty of wiring.
[0028] In some exemplary embodiments, the power control module includes:
[0029] Power interface, used to connect to mains power to provide operating power;
[0030] The power switch is used to control the main unit to turn on or off.
[0031] To achieve the above technical solution, a power cord is connected through a power interface, which is then connected to the mains power to provide power. A power switch facilitates the switching control of the equipment.
[0032] In some exemplary embodiments, the power control module further includes a fuse for fault protection.
[0033] In some exemplary embodiments, the host is also provided with a power indicator light group to indicate the power operating status.
[0034] By implementing the above technical solution, the power indicator light group can enable supervisors to understand the working status of the equipment in a timely manner.
[0035] In summary, compared with the prior art, this utility model has the following beneficial effects:
[0036] This utility model provides a pluggable communication expansion module and hub. The main control board is electrically connected to the host through a plug-in terminal and locked to the host by a mounting part and a locking component. The wiring port is located outside the mounting part, allowing connection to external devices. Since there are various types of wiring ports, multiple sets of this pluggable communication expansion module can be configured on the host to meet different communication connection requirements without the need for multiple types of hubs, thereby reducing usage costs and wiring difficulty. By setting a push component, when different pluggable communication expansion modules need to be disassembled and replaced, the push component generates an elastic force during the disassembly of the locking component, pushing the mounting part outward, thereby achieving quick disassembly of the pluggable communication expansion module, improving replacement efficiency, and further meeting the configuration requirements of different wiring.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0044] like Figures 1 to 4 As shown, this utility model embodiment provides a hub, including: a host 60, the host 60 having a plurality of slots; multiple sets of pluggable communication expansion modules; and a power control module disposed on the host 60 for power supply control of the host 60.
[0045] Specifically, the pluggable communication expansion module includes: a main control board 10, with a plug-in terminal 11 on the first side for electrical connection with the host 60 and a mounting part 12 on the second side; a plurality of wiring ports 20 disposed on the mounting part 12 and connected to the main control board 10, the wiring ports 20 being used for connection with external devices, the wiring ports 20 including one or more combinations of RJ-11 interface, fiber optic interface and BNC interface; a locking member 30 disposed on the mounting part 12 for locking with the host 60, the locking member 30 passing through the mounting part 12, and a pushing component 40 sleeved on the locking member 30, one end abutting against the mounting part 12 and the other end abutting against the connection area provided on the host 60, the pushing component 40 being used to generate elastic force to push the mounting part 12 outward when the locking member 30 is unlocked, causing the plug-in terminal 11 to disengage from the host 60.
[0046] The main control board 10 is equipped with a chipset and peripheral circuits for communication functions. Each pluggable communication expansion module is plugged into a corresponding slot and electrically connected to the host 60 through the plug-in terminal 11. The multiple pluggable communication expansion modules include at least two types of wiring ports 20. The wiring ports 20 can be configured according to wiring needs. In some instances, the RJ-11 interface can also be replaced by an RS232 interface or an RS485 interface, and the fiber optic interface can be an ST interface, an SMA interface, etc.
[0047] The plug-in terminal 11 has conductive plates 13 arranged on it for electrical connection with the host 60, and a positioning slot 14 is provided in the middle of the plug-in terminal 11. The position of the positioning slot 14 is slightly offset from the center of the plug-in terminal 11. It can be understood that a plug-in terminal 11 adapted to the plug-in terminal 11 is provided at a corresponding position on the host 60. Thus, the installation direction of the pluggable communication expansion module can be restricted by the positioning slot 14, thereby improving the accuracy of installation.
[0048] The locking component 30 includes a head and a rod. The head has a slotted or Phillips head for screwdrivers to turn it. The rod has a threaded section. The main unit 60 has a screw block for threaded connection with the rod, thus fixing the pluggable communication expansion module.
[0049] The push-off assembly 40 specifically includes: a pressing sleeve 41 sleeved on the locking member 30, the first end of the pressing sleeve 41 being connected to the mounting portion 12 and the second end passing through the mounting portion 12; and an elastic member 42 sleeved on the locking member 30 and abutting against the second end of the pressing sleeve 41, the other end of the elastic member 42 pressing against the connection area provided on the main unit 60, and the compression amount generated by the elastic member 42 when the locking member 30 is locked is at least equal to the width of the insertion end 11, and the elastic member 42 is a spring.
[0050] The main control board 10 extends from both ends of the mounting part 12, thereby forming the mounting positions for the locking member 30 and the pushing component 40. The mounting part 12 is provided with mounting holes that are adapted to the pressing sleeve 41. The pressing sleeve 41 passes through the mounting holes, and the locking member 30 passes through the pressing sleeve 41. In the locked state, the locking member 30 is locked in the connection area on the host 60. At this time, the elastic member 42 is compressed and generates elastic force, and the amount of compression is at least equal to the width of the plug-in end 11. When the locking member 30 is removed, the elastic member 42 will gradually release the elastic force during the process of loosening the locking member 30. Through this elastic force, the plug-in communication expansion module can be pushed outward by the pressing sleeve 41, thereby causing the plug-in end 11 to be separated from the host 60, realizing the quick disassembly and replacement of the plug-in communication expansion module.
[0051] The first end of the pressure sleeve 41 is provided with an outer pressure ring 411 that expands radially outward, and the second end of the pressure sleeve 41 is provided with an inner pressure ring 412 that contracts radially inward. The inner wall of the inner pressure ring 412 is basically in contact with the rod of the locking member 30, and the rod of the locking member 30 is provided with a smooth rod section that matches the inner pressure ring 412. The outer pressure ring 411, the pressure sleeve 41, and the inner pressure ring 412 are integrally formed. The outer pressure ring 411 facilitates connection with the mounting part 12, and the inner pressure ring 412 can provide sufficient connection or pressure space for the elastic member 42.
[0052] Furthermore, a receiving ring 43 is connected to the end of the elastic member 42 for pressing against the connection area provided on the main unit 60. The inner wall size of the receiving ring 43 is larger than the rod size of the locking member 30. The receiving ring 43 can be fixed to the elastic member 42 by welding, snap-fitting or other means, or it can be set separately from the elastic member 42. The receiving ring 43 can effectively press against the connection area provided on the main unit 60, which helps to apply the elastic force more stably to the mounting part 12.
[0053] Meanwhile, a status indicator light group 50 is also connected to the main control board 10. The status indicator light group 50 is set in the mounting part 12 and is correspondingly set to each wiring port 20. It is used to indicate the working status of each wiring port 20. The status indicator light group 50 indicates the working status, which helps the supervisor to understand the working status in time and handle it. At the same time, it can provide timely prompts when a fault occurs.
[0054] The power control module includes: a power interface 71 for connecting to mains power to provide operating power; and a power switch 72 for controlling the host 60 to turn on or off. Power is supplied by connecting a power cord through the power interface 71 to mains power, while the power switch 72 facilitates the switching control of the device. The power control module also includes a fuse 73 for fault protection.
[0055] Furthermore, a power indicator light group 80 is also provided on the main unit 60 to indicate the power working status. The power indicator light group 80 allows supervisors to understand the working status of the equipment in a timely manner.
[0056] The main control board 10 is electrically connected to the host 60 via the plug-in terminal 11 and is locked onto the host 60 by the mounting part 12 and the locking member 30. The wiring port 20 is located outside the mounting part 12, so it can be connected to external devices. Since there are multiple types of wiring ports 20, when multiple sets of this pluggable communication expansion module are configured on the host 60, different communication connection requirements can be met without setting up multiple types of hubs, thereby reducing the cost of use and the difficulty of wiring. By setting up the push component 40, when it is necessary to disassemble and replace different pluggable communication expansion modules, the push component 40 generates elastic force to push the mounting part 12 outward during the disassembly of the locking member 30, thereby realizing the quick disassembly of the pluggable communication expansion module, improving the replacement efficiency, and further meeting the configuration requirements of different wiring.
[0057] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
