[0058] Please refer to Figures 1 to 6 .

[0059] This specific embodiment discloses an anti-hot-plug method, which is applied to an anti-hot-plug electronic module. The anti-hot-plug electronic module includes a module housing 1, a switching device 13 that can be switched to a first position or a second position, and an early warning component 121 for issuing early warning information. When the switching device 13 is in the second position, at least part of the switching device 13 extends out of the module housing 1. The anti-hot-plug method includes:

[0060] Step S1, determining whether the anti-hot-swap electronic module is in an electrically connected state, if so, proceeding to step S2, if not, proceeding to step S3;

[0061] In step S1, whether the electronic module is in an electrically connected state can be judged directly by using a device such as an electric tester, or by setting an electrical connection indicator light. When it is in an electrically connected state, the electrical connection indicator light is on, and when it is in a power-off state, the electrical connection indicator light is off. It is also possible to set a specific sensor to send a signal when it is in an electrically connected state. Of course, there can be other judgment methods, which are determined according to actual conditions and will not be elaborated here.

[0062] Step S2, determining whether the switching device 13 is switched to the second position, if so, the anti-hot-plug electronic module is in the anti-hot-plug state; if not, controlling the warning component 121 to issue a warning message;

[0063] In step S2, the switching device 13 can switch between the first position and the second position by moving, or by rotating, or by a combination of moving and rotating. The specific method is determined according to actual conditions and will not be elaborated here.

[0064] Step S3, determining whether the switching device 13 is switched to the first position, if so, the anti-hot-swap electronic module is in a pluggable removal or installation state; if not, the anti-hot-swap electronic module is in a fault mode.

[0065] The anti-hot-plug method provided in this specific embodiment is applied to an anti-hot-plug electronic module. The anti-hot-plug electronic module includes a module housing 1, a switching device 13 that can be switched to a first position or a second position, and an early warning component 121 for issuing early warning information. When the switching device 13 is in the second position, it at least partially extends out of the module housing 1, so that the part of the switching device 13 extending out of the module housing 1 is inserted into the housing of an adjacent electronic module, so that the adjacent electronic modules are snap-connected to avoid taking out the electronic modules individually.

[0066] In the process of implementing the anti-hot-swap method provided in this specific embodiment, it is first necessary to determine whether the anti-hot-swap electronic module is in an electrically connected state. If the anti-hot-swap electronic module is in an electrically connected state, determine whether the switching device 13 is switched to the second position. If so, the anti-hot-swap electronic module is in an anti-hot-swap state; if not, control the early warning component 121 to issue an early warning message; if the anti-hot-swap electronic module is in a power-off state, determine whether the switching device 13 is switched to the first position. If so, the anti-hot-swap electronic module is in a pluggable removal or installation state; if not, the anti-hot-swap electronic module is in a fault mode.

[0067] During the implementation of the anti-hot plug method provided in this specific embodiment, it is judged whether the switching device 13 is located in the second position that can prevent hot plugging, so as to determine whether the switching device 13 has moved to the second position normally, and a warning message is issued when the switching device 13 is in an electrically connected state and has not moved to the second position, indicating that hot plugging is not allowed at this time, so as to avoid hot plugging due to the switching device 13 failing to move smoothly to the second position under unexpected circumstances, thereby effectively avoiding the occurrence of hot plugging.

[0068] In a specific embodiment, the anti-hot-swap electronic module further includes a micro switch, and when the switching device 13 is in the first position, the micro switch is in a closed state, and when the switching device 13 is in the second position, the micro switch is in an open state;

[0069] Step S2, determining whether the switching device 13 is switched to the second position, comprises:

[0070] Step S21, obtaining the state information of the micro switch, when the micro switch is in the open state, the switching device 13 switches to the second position.

[0071] In this specific embodiment, the specific structure of the micro switch is not limited. When the micro switch is in the open state, the switching device 13 switches to the second position. When the micro switch is in the connected state, the switching device 13 is located in the first position or within a certain range from the first position.

[0072] In a specific embodiment, the anti-hot-swap electronic module further includes a first detection member and a second detection member, the first detection member is used to detect whether the switching device 13 is located at the first position, and the second detection member is used to detect whether the switching device 13 is located at the second position;

[0073] Step S2, determining whether the switching device 13 is switched to the second position, comprises:

[0074] Step S22, obtaining the position information of the switching device 13 detected by the second detection element, if the second detection element detects the switching device 13, the switching device 13 is switched to the second position;

[0075] Step S3, determining whether the switching device 13 is switched to the first position comprises:

[0076] Step S31 , obtaining the position information of the switching device 13 detected by the first detection element. If the first detection element detects the switching device 13 , the switching device 13 switches to the first position.

[0077] The first detection member and the second detection member can be light sensing members, or position sensors, or other structures that meet the requirements, which are specifically determined according to actual conditions.

[0078] During actual use, if the anti-hot-swap electronic module is in an electrically connected state and the position information of the switching device 13 detected by the second detection component is obtained, the switching device 13 switches to the second position; if the position information of the switching device 13 detected by the first detection component is obtained, the switching device 13 switches to the first position; if the position information of the switching device 13 detected by the first detection component and the second detection component is not obtained, at least one of the first detection component and the second detection component is in a fault state, or the switching device 13 deviates from the first position and the second position.

[0079] In this specific embodiment, the position of the switching device 13 is directly determined by the first detection member and the second detection member, so that the position of the switching device 13 can be determined more directly, which is beneficial to improving the accuracy of the determination of the position of the switching device 13, thereby avoiding hot plugging.

[0080] On the basis of the above embodiment, the anti-hot-swap electronic module can have a micro switch, a first detection member and a second detection member at the same time. Specifically, the anti-hot-swap electronic module also includes a micro switch, a first detection member and a second detection member, and when the switching device 13 is in the first position, the micro switch is in a closed state, and when the switching device 13 is in the second position, the micro switch is in an open state; the first detection member is used to detect whether the switching device 13 is in the first position, and the second detection member is used to detect whether the switching device 13 is in the second position;

[0081] Step S2, determining whether the switching device 13 is switched to the second position, comprises:

[0082] Step S23, obtaining the position information of the switching device 13 detected by the second detection member and the state information of the micro switch, when the micro switch is in the open state and the second detection member detects the switching device 13, the switching device 13 switches to the second position;

[0083] Step S3, determining whether the switching device 13 is switched to the first position comprises:

[0084] Step S32, obtaining the position information of the switching device 13 detected by the first detection member and the state information of the micro switch, when the micro switch is in a closed state and the first detection member detects the switching device 13, the switching device 13 switches to the first position.

[0085] In this specific embodiment, by simultaneously providing a micro switch, a first detection member, and a second detection member, a double judgment is made on the position of the switching device 13, which can effectively improve the accuracy of the judgment on the position of the switching device 13, thereby avoiding hot plugging.

[0086] On the basis of the above embodiment, the warning component 121 may include a warning light and / or a buzzer. In step S2, controlling the warning component 121 to issue a warning message includes:

[0087] Step S24, controlling the warning light to flash; and / or controlling the buzzer to emit a buzzer warning sound.

[0088] Of course, the early warning component 121 can also be other devices, which are determined according to actual conditions and will not be elaborated here.

[0089] In addition to the above-mentioned anti-hot-plug method, the present invention also provides an anti-hot-plug electronic module for implementing the anti-hot-plug method disclosed in the above-mentioned embodiment, and the anti-hot-plug electronic module includes:

[0090] The module housing 1 is provided with a socket 101 and / or a switching device 13 for cooperating with an adjacent anti-heat-swap electronic module.

[0091] The switching device 13 is disposed in the module housing 1, and the switching device 13 can be switched to a first position or a second position; when the switching device 13 is in the first position, it is completely located in the module housing 1; when the switching device 13 is in the second position, it at least partially extends out of the module housing 1;

[0092] The monitoring device 12 includes an early warning component 121 for issuing early warning information and a control component 122 electrically connected to the early warning component 121. The monitoring device 12 is arranged in the module housing 1, and when the hot-swap protection electronic module is in an electrically connected state and the switching device 13 is not switched to the second position, the control component 122 controls the early warning component 121 to issue an early warning message.

[0093] In this specific embodiment, Figure 1 As shown, the module housing 1 is provided with a socket 101. In actual use, the heat-resistant pluggable electronic module can be inserted into the module housing 1. Figure 2 When the switching device 13 is switched to the second position, as shown in FIG. Figure 3 As shown, the switching device 13 extends into the socket 101 of the adjacent anti-heat-plug electronic module to achieve a snap connection, so as to prevent the anti-heat-plug electronic module from being removed in an electrically connected state, thereby preventing hot plugging.

[0094] In the specific use process, when there is no power supply, such as Figure 2 As shown, the switching device 13 is in the first position, the clamping of the adjacent anti-hot-plug electronic module is released, and the anti-hot-plug electronic module can be taken out. Figure 3 As shown, the switching device 13 extends into the socket 101 of the adjacent anti-heat-plug electronic module to achieve a snap connection, so as to prevent the anti-heat-plug electronic module from being removed in an electrically connected state, thereby preventing hot plugging.

[0095] In this specific embodiment, the switching device 13 is switched between the first position and the second position to realize the connection or release of adjacent anti-hot-plug electronic modules to avoid hot plugging. The structure is simple and easy to implement. When the switching device 13 is not switched to the second position that can prevent hot plugging in the electrically connected state, the control component 122 controls the early warning component 121 to issue an early warning message, which can monitor whether it is in a hot plug state to further avoid hot plugging.

[0096] In this specific embodiment, the warning component 121 is a warning light or a buzzer. Of course, it can also be other structures that meet the requirements, which are determined according to actual conditions.

[0097] Specifically, the switching device 13 can be movably arranged on the module housing 1, such as Figure 1 As shown, the module housing 1 is provided with a limiting hole for limiting the movement of the switching device 13 , and the switching device 13 can partially extend out of the limiting hole, or be completely located in the module housing 1 .

[0098] The switching device 13 can also be rotatably arranged in the module housing 1. When the switching device 13 is rotated to the first position, the switching device 13 is completely located in the module housing 1. When the switching device 13 is rotated to the second position, the switching device 13 at least partially extends out of the module housing 1. The switching device 13 can be rotatably arranged in the module housing 1 by a pin shaft, a rotating shaft or a hinge seat, etc., which is determined according to the specific situation.

[0099] The switching device 13 can also be rotatably and movably arranged in the module housing 1. A corresponding slide rail is arranged in the module housing 1. The slide rail has a straight segment and an arc segment. The switching device 13 slides along the slide rail. When the switching device 13 is located in the straight segment, it moves along the straight line. When the switching device 13 is located in the arc segment, the switching device 13 rotates around a certain rotation axis until it rotates to the second position.

[0100] Of course, the switching device 13 may also be configured in other ways, which is determined according to actual conditions.

The switching device 13 includes an electromagnet 10 disposed on the module housing 1 and a movable moving part 11 disposed on the module housing 1; when the electromagnet 10 is powered on, the electromagnet 10 in the adjacent anti-hot-swap electronic module attracts the moving part 11, so that the moving part 11 moves to the second position under the magnetic force of the electromagnet 10.

[0102] like Figure 1 As shown, the first connecting member is a PIN needle 8, the second connecting member is a conductive sheet 9, and a reset spring 2 is sleeved on the outer periphery of the moving member 11, so that when the electromagnet 10 is powered off, the moving member 11 moves to the first position under the elastic force of the reset spring 2; a fixed bracket 5 is fixedly installed on the inner side of the module housing 1 by screws 6, the moving member 11 is located on one side of the fixed bracket 5, and a circuit board 7 and a PIN needle 8 perpendicular to the circuit board 7 are provided on the other side of the fixed bracket 5; the electromagnet 10 can be installed on the circuit board 7.

[0103] like Figure 1 As shown, an insulating member 3 is provided between the conductive sheet 9 and the ferromagnetic structure 4 to prevent leakage when the conductive sheet 9 is connected to the PIN needle 8. Specifically, the movable member 11 can be directly set to an insulating material, or an insulating material can be sleeved on the periphery of the movable member 11.

[0104] In the specific use process, in the power-off state, the electromagnet 10 has no magnetism, and under the elastic force of the reset spring 2, the moving member 11 moves to a position abutting against the fixed bracket 5. Figure 2 As shown, the conductive sheet 9 is electrically connected to the PIN, and the hot plug protection is released; in the electrically connected state, as shown Figure 3 As shown, the electromagnet 10 in the adjacent anti-hot-swap electronic module attracts the moving part 11, and the magnetic force generated on the moving part 11 is greater than the elastic force of the reset spring 2. Under the action of the magnetic force, the moving part 11 moves away from the electromagnet 10 and is inserted from the extended module housing 1 into the jack 101 of the adjacent module housing 1. At this time, the anti-hot-swap electronic module is in the anti-hot-swap state; in the electrically connected state, as shown Figure 4 As shown, due to the obstruction of the module housing 1, the moving part 11 cannot normally extend out of the module housing 1. At this time, the conductive sheet 9 is electrically connected to the PIN, and the warning component 121 issues a warning message.

[0105] In this specific embodiment, the moving part 11 can be made of a ferromagnetic material or a permanent magnet, which is determined according to actual conditions.

[0106] In the power-on state, when the moving part 11 is a permanent magnet, the following Figure 3 The electromagnet 10 in the same anti-hot-plug electronic module is opposite to the moving part 11 with the same pole, and the electromagnet 10 in the adjacent anti-hot-plug electronic module is opposite to the moving part 11 with different poles. The adjacent anti-hot-plug electronic module mentioned here refers to the adjacent anti-hot-plug electronic module that is close to the moving part 11.

[0107] In addition to the structural form of the conductive sheet 9 and the PIN needle 8, the micro switch may also have other structural forms, which are determined according to actual conditions and will not be described in detail here.

[0108] Furthermore, in order to enable the moving part 11 to be smoothly inserted into the socket 101 of the adjacent mold shell, a ferromagnetic structure 4 can be provided at one end of the moving part 11 extending out of the module shell 1. The ferromagnetic structure 4 is used to cooperate with the electromagnet 10 in the adjacent hot-swap anti-electronic module to attract and engage, so that the plug-in fit between the moving part 11 and the adjacent mold shell is more reliable in the hot-swap anti-state.

[0109] In a specific embodiment, the control component 122 can also include a first detection component and a second detection component, the first detection component is used to detect whether the switching device 13 is located in the first position, and the second detection component is used to detect whether the switching device 13 is located in the second position, and the first detection component and the second detection component are both connected to the control component 122.

[0110] The first detection member and the second detection member can be position sensors. During specific use, in the power-off state, the electromagnet 10 does not have magnetism. Under the elastic force of the reset spring 2, the moving member 11 moves to a position abutting against the fixed bracket 5. At this time, the switching device 13 moves to the first position, and the first detection member detects that the switching device 13 is located in the first position, and the hot-swap protection is released; in the electrically connected state, the electromagnet 10 in the adjacent hot-swap protection electronic module attracts the moving member 11, and the magnetic force generated on the moving member 11 is greater than the elastic force of the reset spring 2. Under the action of the magnetic force, the moving member 11 moves away from the electromagnet 10 in the hot-swap protection electronic module, and extends out of the module housing 1 and inserts into the jack 101 of the adjacent module housing 1. The second detection member detects that the switching device 13 is located in the second position, and the hot-swap protection electronic module is in the hot-swap protection state; in the electrically connected state, the moving member 11 cannot extend out of the module housing 1 normally due to the obstruction of the module housing 1, the second detection member cannot detect the switching device 13, and the warning component 121 issues a warning message.

[0111] The electromagnet 10 mentioned in the above embodiment can be magnetic when powered on and lose its magnetism when powered off. Of course, the electromagnet 10 can also lose its magnetic force when powered on and lose its attraction to the moving part 11. The moving part 11 moves to the second position under the action of the reset spring 2. The electromagnet 10 has magnetic force when powered off, and generates suction force on the moving part 11, so that the moving part 11 overcomes the elastic force of the reset spring 2 and moves to the first position.

[0112] In addition to the above-mentioned anti-hot-swap electronic module, this specific embodiment also provides an electronic device including at least one of the above-mentioned anti-hot-swap electronic modules.

[0113] When the electronic device includes only one anti-hot-plug electronic module, when the switch device 13 is located at the second position, it can be snap-fitted with the housing of other adjacent devices, or snap-fitted with the housing of the electronic device, which is determined according to actual conditions.

[0114] When the electronic device includes a plurality of heat-resistant pluggable electronic modules, the structure of each heat-resistant pluggable electronic module can be made the same to facilitate processing.
