Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a communication device, a system terminal block, and a communication module. Background Technology

[0002] Communication power supply equipment is crucial for ensuring the safe and reliable operation of communication systems. Communication power supply equipment is typically an uninterruptible power supply (UPS), usually including a rectifier module, battery pack, and communication inverter module. In existing technologies, when the rectifier module of the communication power supply equipment is connected to the system terminal block via plugging and unplugging, hot-plugging issues may occur during the process, causing damage to the connector terminals on the module. Summary of the Invention

[0003] The present invention provides a communication device, a system terminal block, and a communication module. The communication device can avoid hot-plugging problems and prevent high current from damaging the communication module and the terminal block.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A communication device, comprising:

[0006] The system terminal block has a plug-in end on its first plane. The plug-in end includes a first contact surface perpendicular to the first plane. A first conductive terminal and a second conductive terminal are disposed on the first contact surface. The first conductive terminal includes a first conductive area and a second conductive area. The first conductive area, the second conductive area and the second conductive terminal are arranged along a first direction, which is the extension direction of the intersection line between the first plane and the first contact surface.

[0007] A communication module includes a plug-in connector and a first resistor. The plug-in connector includes a second plane and a first plug-in surface perpendicular to the second plane. The first plug-in surface includes a first plug-in terminal and a second plug-in terminal. The first plug-in terminal includes a first sub-terminal and a second sub-terminal. The first sub-terminal, the second sub-terminal, and the second plug-in terminal are arranged along a second direction, which is the extension direction of the intersection line between the second plane and the first plug-in surface. The two ends of the first resistor are respectively connected to the first sub-terminal and the second sub-terminal. The plug-in connector has a plug-in alignment position and a fully inserted position.

[0008] When the plug-in connector is located at the plug-in alignment position, the second plane is parallel to the first plane and opposite to the plug-in end. The first sub-terminal, the second sub-terminal, and the second plug-in terminal are respectively opposite to the first conductive area, the second conductive area, and the second conductive terminal. The distance between the first sub-terminal and the first conductive area and the distance between the second plug-in terminal and the second conductive terminal are both less than the distance between the second sub-terminal and the second conductive area.

[0009] When the plug-in connector is in the fully inserted position, the plug-in connector is inserted into the plug-in end, and the first sub-terminal, the second sub-terminal, and the second plug-in terminal are in contact with the first conductive area, the second conductive area, and the second conductive terminal, respectively.

[0010] In the communication device provided in this embodiment of the invention, the first conductive terminal and the second conductive terminal on the plug-in end of the system terminal block can be connected to the first electrode and the second electrode of the power supply, respectively. The first plug-in terminal and the second plug-in terminal on the plug-in connector of the communication module can be connected to the first end and the second end of the input side of the communication module, respectively. When the first plug-in terminal and the second plug-in terminal are connected to the first conductive terminal and the second conductive terminal, respectively, a circuit can be formed between the power supply and the communication module. Since the distance between the first sub-terminal of the first plug-in terminal and the first conductive area of ​​the first conductive terminal, and the distance between the second plug-in terminal and the second conductive terminal, are both less than the distance between the second sub-terminal of the first plug-in terminal and the second conductive area of ​​the first conductive terminal when the plug-in connector of the communication module is inserted into the plug-in end of the system terminal block, the first sub-terminal of the first plug-in terminal and the first conductive area of ​​the first conductive terminal, and the second plug-in terminal and the second conductive terminal, come into contact first during the process of the plug-in connector of the communication module being inserted into the plug-in end of the system terminal block. At this point, the first electrode of the power supply, the first terminal of the communication module input side, the capacitors connected to both ends of the communication module input side, the first resistor, and the second terminal of the power supply at the second terminal of the communication module input side form a circuit to charge the capacitors connected to both ends of the communication module input side. The first resistor limits the charging current, preventing hot-plugging issues and protecting the communication module and terminal block from high current damage. When the communication module's plug-in connector is further inserted into the system terminal block, the second sub-terminal of the first plug-in terminal also contacts the second conductive area of ​​the first conductive terminal, resulting in large-area contact between the first plug-in terminal and the first conductive terminal. This allows the communication module to power on normally. At this time, the first and second sub-terminals of the first plug-in terminal short-circuit the first resistor, preventing the resistor from continuously consuming energy.

The second plug-in surface is provided with a third plug-in terminal and a fourth plug-in terminal arranged along the fourth direction, where the fourth direction is the extension direction of the intersection line between the second plug-in surface and the second plane. The third plug-in terminal is electrically connected to the first plug-in terminal, and the fourth plug-in terminal is electrically connected to the second plug-in terminal.

Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please refer to Figure 1 , Figure 2 and Figure 3 The present invention provides a communication device, comprising:

[0048] System terminal block 100, such as Figure 1As shown, the first plane A of the system terminal block 100 is provided with a plug-in end 1. The plug-in end 1 includes a first contact surface 11 perpendicular to the first plane A. A first conductive terminal 111 and a second conductive terminal 112 are provided on the first contact surface 11. The first conductive terminal 111 includes a first conductive area 1111 and a second conductive area 1112. The first conductive area 1111, the second conductive area 1112 and the second conductive terminal 112 are arranged along a first direction, which is the extension direction of the line intersecting the first plane A and the first contact surface 11.

[0049] Communication module 200, such as Figure 2 As shown, the communication module 200 includes a plug-in connector 2 and a first resistor R1. The plug-in connector 2 includes a second plane B and a first plug-in surface 21 perpendicular to the second plane B. The first plug-in surface 21 includes a first plug-in terminal 211 and a second plug-in terminal 212. The first plug-in terminal 211 includes a first sub-terminal 2111 and a second sub-terminal 2112. The first sub-terminal 2111, the second sub-terminal 2112, and the second plug-in terminal 212 are arranged along a second direction, which is the extension direction of the intersection line between the second plane B and the first plug-in surface 21. The two ends of the first resistor R1 are respectively connected to the first sub-terminal 2111 and the second sub-terminal 2112. The plug-in connector 2 has a plug-in alignment position and a fully inserted position.

[0050] When the plug-in connector 2 is in the plug-in alignment position, such as Figure 3 As shown, the second plane B is parallel to the first plane A and opposite to the plug-in end 1. The first sub-terminal 2111, the second sub-terminal 2112, and the second plug-in terminal 212 are respectively opposite to the first conductive area 1111, the second conductive area 1112, and the second conductive terminal 112. The distance between the first sub-terminal 2111 and the first conductive area 1111, and the distance between the second plug-in terminal 212 and the second conductive terminal 112 are both less than the distance between the second sub-terminal 2112 and the second conductive area 1112.

[0051] When the plug-in connector 2 is in the fully inserted position, the plug-in connector 2 is inserted into the plug-in end 1, and the first sub-terminal 2111, the second sub-terminal 2112 and the second plug-in terminal 212 are in contact with the first conductive area 1111, the second conductive area 1112 and the second conductive terminal 112, respectively.

[0052] In the communication device provided in this embodiment of the invention, the first conductive terminal 111 and the second conductive terminal 112 on the plug-in end 1 of the system terminal block 100 can be connected to the first electrode and the second electrode of the power supply, respectively. The first plug-in terminal 211 and the second plug-in terminal 212 on the plug-in connector 2 of the communication module 200 can be connected to the first end and the second end of the input side of the communication module 200, respectively. When the first plug-in terminal 211 and the second plug-in terminal 212 are connected to the first conductive terminal 111 and the second conductive terminal 112, respectively, a circuit can be formed between the power supply and the communication module 200. Since when the plug-in connector 2 is in the plug-in alignment position, the distance between the first sub-terminal 2111 of the first plug-in terminal 211 and the first conductive area 1111 of the first conductive terminal 111, and the distance between the second plug-in terminal 212 and the second conductive terminal 112 are both less than the distance between the second sub-terminal 2112 of the first plug-in terminal 211 and the second conductive area 1112 of the first conductive terminal 111, during the process of the plug-in connector 2 of the communication module 200 being inserted into the plug-in terminal 1 of the system terminal block 100, the first sub-terminal 2111 of the first plug-in terminal 211 and the first conductive area 1111 of the first conductive terminal 111, and the second plug-in terminal 212 and the second conductive terminal 112 make contact first. At this time, the first electrode of the power supply, the first terminal of the input side of the communication module 200, the capacitors connected to both ends of the input side of the communication module 200, the first resistor, and the second terminal of the power supply at the second end of the input side of the communication module 200 can form a circuit to charge the capacitors connected to both ends of the input side of the communication module 200. At this time, the first resistor limits the charging current, which can avoid the problem of hot plugging and prevent the large current from damaging the communication module 200 and the system terminal block 100. When the plug-in connector 2 of the communication module 200 is further inserted into the plug-in terminal 1 of the system terminal block 100, the second sub-terminal 2112 of the first plug-in terminal 211 also contacts the second conductive area 1112 of the first conductive terminal 111, so that the first plug-in terminal 211 and the first conductive terminal 111 have a large-area contact, and the communication module 200 can be powered on normally. At this time, the first sub-terminal 2111 and the second sub-terminal 2112 of the first plug-in terminal 211 short-circuit the first resistor to prevent the resistor from continuously consuming energy.

[0053] In the above embodiments of the invention, the first electrode of the power supply can be the negative electrode and the second electrode can be the positive electrode; or, the first electrode of the power supply can be the positive electrode and the second electrode can be the negative electrode, without limitation, depending on the actual situation; the power supply can be a battery pack connected to the system terminal block 100.

[0054] In the above embodiments of the invention, in order to ensure that when the plug-in connector 2 is located at the plug-in alignment position, the distance between the first sub-terminal 2111 of the first plug-in terminal 211 and the first conductive area 1111 of the first conductive terminal 111, and the distance between the second plug-in terminal 212 and the second conductive terminal 112 are both less than the distance between the second sub-terminal 2112 of the first plug-in terminal 211 and the second conductive area 1112 of the first conductive terminal 111, the following two methods can be used to set the distance.

[0055] In the first method: the distance between the first conductive area 1111 and the first plane A, and the distance between the second conductive terminal 112 and the first plane A, are both less than the distance between the second conductive area 1112 and the first plane A. The distances between the first sub-terminal 2111, the second sub-terminal 2112, and the second plug-in terminal 212 and the second plane B are equal. Figure 3 As shown. In this method, the ends of the first conductive terminal 111 and the second conductive terminal 112 on the system terminal block 100 are not flush, while the ends of the first plug-in terminal 211 and the second plug-in terminal 212 on the communication module 200 are flush. This makes the distance between the terminals on the system terminal block 100 and the terminals on the communication module 200 different during insertion. The structure is simple and easy to implement.

[0056] The second method involves equidistant distances between the first conductive area 1111, the second conductive area 1112, and the second conductive terminal 112 and the first plane A. The distances between the first sub-terminal 2111 and the second plane B, and between the second plug-in terminal 212 and the second plane B, are both less than the distance between the second sub-terminal 2112 and the second plane B. In this method, the ends of the first conductive terminal 111 and the second conductive terminal 112 on the system terminal block 100 are flush, while the first sub-terminal 2111, the second sub-terminal 2112, and the second plug-in terminal 212 on the communication module 200 are not flush. This results in varying distances between the terminals on the system terminal block 100 and the terminals on the communication module 200 during insertion, leading to a simple structure that is easy to implement.

[0057] In the above embodiments of the invention, the width of the first conductive area 1111 along the first direction can be set to be smaller than the width of the second conductive area 1112 along the first direction, which can reduce the value of the charging current when the first sub-terminal 2111 contacts the first conductive area 1111 first, and prevent the large current from damaging the communication module 200 and the system terminal block 100.

[0058] In the above embodiments of the invention, such as Figure 4As shown, the plug-in end 1 may further include a second contact surface 12 perpendicular to the first plane A. The second contact surface 12 is provided with a third conductive terminal 121 and a fourth conductive terminal 122 arranged along a third direction. The third direction is the extension direction of the intersection line between the second contact surface 12 and the first plane A. The third conductive terminal 121 is electrically connected to the first conductive terminal 111, and the fourth conductive terminal 122 is electrically connected to the second conductive terminal 112.

[0059] Specifically, such as Figure 5 As shown, the plug-in connector 2 may further include a second plug-in surface 22 perpendicular to the second plane B. The second plug-in surface 22 is provided with a third plug-in terminal 221 and a fourth plug-in terminal 222 arranged along a fourth direction, which is the extension direction of the intersection line between the second plug-in surface 22 and the second plane B. The third plug-in terminal 221 is electrically connected to the first plug-in terminal 211, and the fourth plug-in terminal 222 is electrically connected to the second plug-in terminal 212.

[0060] When the plug-in connector 2 is in the plug-in alignment position, such as Figure 6 As shown, the third plug-in terminal 221 and the fourth plug-in terminal 222 are respectively opposite to the third conductive terminal 121 and the fourth conductive terminal 122. The distance between the third plug-in terminal 221 and the third conductive terminal 121 is greater than the distance between the first sub-terminal 2111 and the first conductive area 1111.

[0061] When the plug-in connector 2 is in the fully inserted position, the third plug-in terminal 221 and the fourth plug-in terminal 222 are in contact with the third conductive terminal 121 and the fourth conductive terminal 122, respectively.

[0062] In the aforementioned communication device, the plug-in terminal 1 also has a second contact surface 12. Since the third conductive terminal 121 on the second contact surface 12 is electrically connected to the first conductive terminal 111 on the first contact surface 11, and the fourth conductive terminal 122 on the second contact surface 12 is electrically connected to the second conductive terminal 112 on the first contact surface 11, the third conductive terminal 121 and the third plug-in terminal 221 can be configured such that, when the plug-in connector 2 is in the plug-in alignment position, the distance between the third plug-in terminal 221 and the third conductive terminal 121 is greater than the distance between the first sub-terminal 2111 and the first conductive area 1111. This ensures that during the plugging process, the contact between the third plug-in terminal 221 and the third conductive terminal 121 occurs later than the contact between the first sub-terminal 2111 and the first conductive area 1111, thus limiting the charging current. For example, when the plug-in connector 2 is in the plug-in alignment position, the distance between the third plug-in terminal 221 and the third conductive terminal 121 is equal to the distance between the second sub-terminal 2112 and the second conductive area 1112. When the plug-in connector 2 is in the plug-in alignment position, the distance between the fourth conductive terminal 122 and the fourth plug-in terminal 222 is not limited and can be determined according to the actual situation. For example, when the plug-in connector 2 is in the plug-in alignment position, the distance between the fourth conductive terminal 122 and the fourth plug-in terminal 222 is equal to the distance between the second conductive terminal 112 and the second plug-in terminal 212.

[0063] In the above embodiments of the invention, specifically, in order to ensure that when the plug-in connector 2 is located at the plug-in alignment position, the distance between the third plug-in terminal 221 and the third conductive terminal 121 is greater than the distance between the first sub-terminal 2111 and the first conductive area 1111, it can be set in the following two ways.

[0064] In the first method, the distance between the third conductive terminal 121 and the first plane A is greater than the distance between the first conductive area 1111 and the first plane A, and the distances between the third plug-in terminal 221 and the fourth plug-in terminal 222 and the second plane B are equal. Figure 6 As shown; that is, the ends of the third conductive terminal 121 and the fourth conductive terminal 122 are not flush, while the ends of the third plug-in terminal 221 and the fourth plug-in terminal 222 are flush, so that the distance between the terminals on the system terminal block 100 and the terminals on the communication module 200 is different during insertion. The structure is simple and easy to implement.

[0065] In the second method, the distances between the third conductive terminal 121 and the fourth conductive terminal 122 and the first plane A are equal, and the distance between the third plug-in terminal 221 and the second plane B is greater than the distance between the first sub-terminal 2111 and the second plane B; that is, the ends of the third conductive terminal 121 and the fourth conductive terminal 122 are flush, while the ends of the third plug-in terminal 221 and the fourth plug-in terminal 222 are not flush, so that the distance between the terminals on the system terminal block 100 and the terminals on the communication module 200 varies during insertion. This method has a simple structure and is easy to implement.

[0066] In the above embodiments of the invention, specifically, the communication device can be a communication power supply device or other communication devices, without limitation, such as a tower server; the communication module 200 can be a rectifier module, communication inverter module, UPS module, etc. of the communication power supply device, or it can also be a communication module on other communication devices, such as a communication module on a tower server, without limitation. However, during the insertion and insertion of the communication module 200 with the system terminal block 100, not only hot-plugging issues may occur, but also hot-swapping issues. For example, the communication inverter module in the communication power supply device is suitable for various digital communication devices, information network system servers, switches, and other places in communication equipment rooms that require 220V AC power. The communication inverter module can operate in a battery-powered (or rectifier module-powered) environment with 220V AC output. Without hot-swapping, arcing or sparking may occur when the communication inverter module is pulled out while energized, damaging the terminals and reducing their lifespan.

[0067] In the above embodiments of the invention, specifically, as shown in the example below... Figure 6 As shown, a first detection terminal 123 may also be provided on the second contact surface 12. The first detection terminal 123 includes a first detection area 1231 and a second detection area 1232 arranged along a third direction. A second detection terminal 223 and a third detection terminal 224 are also provided on the second insertion surface 22. The communication module 200 also includes a hot-swap detection circuit 3, with its two ends connected to the second detection terminal 223 and the third detection terminal 224, respectively.

[0068] When the plug-in connector 2 is in the plug-in alignment position, the second detection terminal 223 and the third detection terminal 224 are opposite to the first detection area 1231 and the second detection area 1232, respectively. The distance between the third detection terminal 224 and the second detection area 1232 is greater than the distance between the second detection terminal 223 and the first detection area 1231, the distance between the second conductive area 1112 and the second sub-terminal 2112, the distance between the third conductive terminal 121 and the third plug-in terminal 221, and the distance between the fourth conductive terminal 122 and the fourth plug-in terminal 222.

[0069] When the plug-in connector 2 is in the fully inserted position, the second detection terminal 223 and the third detection terminal 224 are in contact with the first detection area 1231 and the second detection area 1232, respectively.

[0070] Specifically, the hot-swap detection circuit 3 can be used to control the communication module 200 to shut down its output when the second detection terminal 223 is in contact with the first detection area 1231 and the third detection terminal 224 is not in contact with the second detection area 1232, and to control the communication module 200 to output normally when the second detection terminal 223 and the third detection terminal 224 are in contact with the first detection area 1231 and the second detection area 1232 respectively.

[0071] In the above embodiments of the invention, when the plug-in connector 2 on the communication module 200 is inserted into the plug-in terminal 1 of the system terminal block 100, the terminals on the plug-in connector 2 and the terminals on the plug-in terminal 1 are in complete contact. The hot-swap detection circuit will detect whether the communication module 200 is properly inserted, that is, whether the second detection terminal 223 is in contact with the first detection area 1231 and the third detection terminal 224 is in contact with the second detection area 1232. If the communication module 200 is not properly inserted, the hot-swap detection circuit 3 can control the communication module 200 to shut down its output; and when During the process of unplugging the connector 2 of the communication module 200 from the plug-in terminal 1, the second detection area 1232 and the third detection terminal 224 first lose contact, while the other terminals on the communication module 200 and the system terminal block 100 are still in normal contact. The hot-plug detection circuit 3 detects that the communication module 200 has been unplugged and can control the communication module 200 to shut down its output, so that the connector 2 of the communication module 200 is unenergized and unplugged, avoiding arcing and burning at the terminal connection when plugging and unplugging with power, thus avoiding hot-plugging problems.

[0072] Specifically, the aforementioned hot-plug detection circuit 3 may include a second resistor R2, a third resistor R3, an optocoupler U, and a processor, such as... Figure 7 As shown; wherein, the second detection terminal 223 is connected to the first pin of the input terminal of the optocoupler U and to the first ground terminal GND; the third detection terminal 224 is connected to the second pin of the input terminal of the optocoupler U; the first end of the second resistor R2 is connected to the power supply terminal VCC and the second end is connected to the second pin of the input terminal of the optocoupler U; the first end of the third resistor R3 is connected to the second pin of the input terminal of the optocoupler U and the second end is connected to the first pin of the input terminal of the optocoupler U; the third and fourth pins of the output terminal of the optocoupler U are respectively connected to the processor and the second ground terminal GND1; the processor is specifically used to control the communication module 200 to shut down the output when the optocoupler U is on, and to control the communication module 200 to output normally when the optocoupler U is not on.

[0073] In the above embodiments of the invention, when the plug-in connector 2 of the communication module 200 is inserted into the plug-in terminal 1 of the system terminal block 100, the second detection terminal 223 first contacts the first detection area 1231 of the first detection terminal 123, and the third detection terminal 224 then contacts the second detection area 1232 of the first detection terminal 123. When the second detection terminal 223 and the third detection terminal 224 are in contact with the first detection area 1231 and the second detection area 1232 respectively, after the communication module 200 is powered on, the second detection terminal 223 and the third detection terminal 224 are connected, causing a short circuit between the two pins of the optocoupler input terminal. There is no voltage difference, and the optocoupler... If the connector is not conducting and the processor does not detect a signal, it proves that the communication module 200 is working normally, the system terminal block 100 is in good contact with the communication module 200, and the communication module 200 is controlling normal output. However, when the plug-in connector 2 is pulled out, the third detection terminal 224 and the second detection area 1232 first lose contact. At this time, the circuit between the second detection terminal 223 and the third detection terminal 224 is broken, and there is a voltage difference between the two pins of the input terminal of the optocoupler. The optocoupler conducts, the processor detects the signal, and controls the communication module 200 to shut down the output, so that the communication module 200 is pulled out without power, avoiding arcing and popping at the terminal connection when plugging and unplugging.

[0074] In the above embodiments of the invention, specifically, as shown in the example below... Figure 6 As shown, in order to realize the detection function of the hot-plug detection circuit 3, it can be specifically configured such that the distances between the third detection terminal 224, the second detection terminal 223, the second sub-terminal 2112, the third plug-in terminal 221, and the fourth plug-in terminal 222 and the second plane B are equal, and the distance between the second detection area 1232 and the first plane A is greater than the distances between the first detection area 1231, the second conductive area 1112, the third conductive terminal 121, and the fourth conductive terminal 122 and the first plane A. Specifically, it can also be configured such that the distances between the first sub-terminal 2111, the second plug-in terminal 212, the third detection terminal 224, the second detection terminal 223, the second sub-terminal 2112, the third plug-in terminal 221, and the fourth plug-in terminal 222 and the second plane B are equal, that is, the ends of the terminals on the plug-in connector 2 are all flush, while the ends of the terminals on the plug-in terminal 1 are not flush.

[0075] Optionally, to enable the hot-plug detection circuit 3 to perform its detection function, the distance between the third detection terminal 224 and the second plane B can be configured such that the distance between the second detection terminal 223, the second sub-terminal 2112, the third plug-in terminal 221, and the fourth plug-in terminal 222 and the second plane B is greater than the distance between them. Furthermore, the distances between the second detection area 1232, the first detection area 1231, the second conductive area 1112, the third conductive terminal 121, and the fourth conductive terminal 122 and the first plane A are equal. Specifically, the distances between the second detection area 1232, the first detection area 1231, the first conductive area 1111, the second conductive area 1112, the second conductive terminal 112, the third conductive terminal 121, and the fourth conductive terminal 122 and the first plane A can all be equal, meaning the ends of the terminals on the plug-in connector 2 are not flush, while the ends of the terminals on the plug-in terminal 1 are flush.

[0076] In the above embodiments of the invention, specifically, the structure of the plug-in end 1 can be that the first contact surface 11 and the second contact surface 12 are parallel to each other, and there is a first plug-in gap between the first contact surface 11 and the second contact surface 12. The structure of the plug-in connector 2 can be that the first plug-in surface 21 and the second plug-in surface 22 are located on two parallel sides of the plug-in connector 2. The plug-in connector 2 can be inserted into the first plug-in gap. The structure is simple and easy to set up.

[0077] Optionally, the structure of the plug-in end can also be: the plug-in end 1 has a plug-in block, the first contact surface 11 and the second contact surface 12 are located on two parallel side surfaces of the plug-in block, and the structure of the plug-in connector 2 can also be that a plug-in groove is provided on the second plane B of the plug-in connector 2, the first plug-in surface 21 and the second plug-in surface 22 are located on two parallel side walls of the plug-in groove, and there is a second plug-in gap between the first plug-in surface 21 and the second plug-in surface 22.
