If yes, the heat-resistant pluggable electronic module is in a heat-resistant pluggable state; if no, the pre-warning component 121 is controlled to send a pre-warning information. If the heat-resistant pluggable electronic module is in a power-off state, whether the switching device 13 is switched to the first position is determined. If yes, the heat-resistant pluggable electronic module is in a pluggable, removable or installable state; if no, the heat-resistant pluggable electronic module is in a fault mode.

[0067] The method for preventing hot plugging provided in the embodiment can determine whether the switching device 13 is located at the second position where the hot plugging can be prevented, to determine whether the switching device 13 is normally moved to the second position, and send a warning information when the electrical connection state is in the electrical connection state and the switching device 13 is not moved to the second position, to prompt that the hot plugging cannot be performed at this time, to avoid the hot plugging phenomenon caused by the fact that the switching device 13 cannot be smoothly moved to the second position under unexpected conditions, and to effectively avoid the occurrence of the hot plugging phenomenon.

[0072] In an embodiment, the electronic module for preventing hot plugging further comprises 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] In step S2, it is determined whether the switching device 13 is switched to the second position, including:

[0074] In step S22, the position information of the switching device 13 detected by the second detection member is acquired, and the switching device 13 is switched to the second position when the second detection member detects the switching device 13.

[0076] In step S31, the position information of the switching device 13 detected by the first detection member is acquired, and the switching device 13 is switched to the first position when the first detection member detects the switching device 13.

[0077] The first detection member and the second detection member can be light sensing members, position sensors, or other structures meeting the requirements, and the specific structure is determined according to the actual situation.

[0078] In actual use, if the heat-proof plug-pull electronic module is in an electrically connected state and the position information of the switching device 13 detected by the second detection member is obtained, the switching device 13 is switched to the second position; if the position information of the switching device 13 detected by the first detection member is obtained, the switching device 13 is switched to the first position; and if the position information of the switching device 13 detected by neither the first detection member nor the second detection member is obtained, at least one of the first detection member and the second detection member is in a fault state, or the switching device 13 deviates from the first position and the second position.

[0079] In the embodiment, the position of the switching device 13 is directly judged by the first detection member and the second detection member, the position of the switching device 13 can be more directly judged, the accuracy of judging the position of the switching device 13 is improved, and thus the plug-pull is avoided.

[0080] On the basis of the above embodiment, the heat-proof plug-pull electronic module can simultaneously have a microswitch, the first detection member and the second detection member. Specifically, the heat-proof plug-pull electronic module further comprises a microswitch, the first detection member and the second detection member, and when the switching device 13 is in the first position, the microswitch is in a closed state, and when the switching device 13 is in the second position, the microswitch 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.

[0086] Based on the above embodiments, the warning component 121 may include a warning light and / or a buzzer. Step S2, controlling the warning component 121 to issue a warning message, includes:

[0087] Step S24: Control the warning light to flash; and / or control the buzzer to emit a beeping warning sound.

[0088] Of course, the early warning component 121 can also be other devices, depending on the actual situation, which will not be elaborated here.

[0089] In addition to the above-described hot-swap prevention methods, the present invention also provides a hot-swap prevention electronic module including a method for implementing the hot-swap prevention methods disclosed in the above embodiments, the hot-swap prevention electronic module comprising:

[0090] The module housing 1 is provided with a socket 101 and / or a switching device 13 for mating with an adjacent hot-swappable electronic module.

[0091] A switching device 13 is disposed in the module housing 1. 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 inside the module housing 1. When the switching device 13 is in the second position, it extends at least partially out of the module housing 1.

[0092] The monitoring device 12 includes a warning component 121 for issuing warning information and a control component 122 electrically connected to the warning component 121. The monitoring device 12 is disposed in the module housing 1. When the hot-swappable 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 warning component 121 to issue warning information.

[0093] In this specific embodiment, such as Figure 1 As shown, the module housing 1 is provided with a socket 101, which allows for the insertion of hot-swappable electronic modules such as... Figure 2 As shown, they are arranged side by side. When the switching device 13 is switched to the second position, as... Figure 3 As shown, the switching device 13 extends into the socket 101 of the adjacent hot-swappable electronic module to achieve a snap-fit, so as to avoid removing the hot-swappable electronic module in the electrical connection state and avoid hot-swapping.

[0094] In actual use, when there is no power, such as Figure 2 As shown, when the switching device 13 is in the first position, the latch of the adjacent hot-swappable electronic module is released, allowing the hot-swappable electronic module to be removed. When the switching device 13 is in the second position, as... Figure 3 As shown, the switching device 13 extends into the socket 101 of the adjacent hot-swappable electronic module to achieve a snap-fit, so as to avoid removing the hot-swappable electronic module in the electrical connection state and avoid hot-swapping.

[0095] In the embodiment, the clamping or releasing of the adjacent hot-plug prevention electronic module is achieved by switching the switching device 13 between the first position and the second position, so as to avoid the hot-plug, and the structure is simple and easy to realize. When the switching device 13 is not switched to the second position for preventing the hot-plug in the electrically connected state, the control assembly 122 controls the early warning assembly 121 to send the early warning information, so as to monitor whether the hot-plug state exists, and further avoid the hot-plug.

[0096] In the embodiment, the early warning assembly 121 is a warning light or a buzzer, and of course, it can also be other structures meeting the requirements, which is determined according to the actual situation.

[0097] Specifically, the switching device 13 can be movably arranged in the module shell 1, as shown in the drawings. Figure 1 The module shell 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 completely be located in the module shell 1.

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

[0099] The switching device 13 can also be rotatably arranged in the module shell 1. When the switching device 13 is rotated to the first position, the switching device 13 is completely located in the module shell 1. When the switching device 13 is rotated to the second position, the switching device 13 at least partially extends out of the module shell 1. The switching device 13 can be rotatably arranged in the module shell 1 through a pin shaft or a rotating shaft or a hinged seat, which is determined according to the situation.

[0100] Of course, the switching device 13 can also be arranged in other ways, which is determined according to the actual situation.

[0101] In a specific embodiment, the control assembly 122 comprises a circuit board 7 provided with the early warning assembly 121, a micro switch electrically connected with the early warning assembly 121, and a controller mounted on the circuit board 7; the micro switch comprises a first connecting piece fixed to the circuit board 7 and a second connecting piece fixed to the switching device 13, and when the switching device 13 is in the second position, the first connecting piece and the second connecting piece are in a disconnected state, and when the switching device 13 is in the first position or a position between the first position and the second position, the first connecting piece and the second connecting piece are in a connected state. The switching device 13 comprises an electromagnet 10 arranged in the module housing 1 and a movable moving piece 11 arranged in the module housing 1; when the electromagnet 10 is in an energized state, the electromagnet 10 in the adjacent heatproof plug-pull electronic module attracts the moving piece 11, so that the moving piece 11 moves to the second position under the magnetic force of the electromagnet 10.

[0102] As shown in Figure 1 , the first connecting piece is a PIN pin 8, the second connecting piece is a conductive sheet 9, and the moving piece 11 is sleeved with a return spring 2 on the outer periphery, so that when the electromagnet 10 is in a de-energized state, the moving piece 11 moves to the first position under the elastic force of the return spring 2; the inner side of the module housing 1 is fixedly installed with a fixed support 5 through a screw 6, the moving piece 11 is located on one side of the fixed support 5, and the other side of the fixed support 5 is provided with the circuit board 7 and the PIN pin 8 perpendicular to the circuit board 7; the electromagnet 10 can be installed on the circuit board 7.

[0103] As shown in Figure 1 , an insulating piece 3 is arranged between the conductive sheet 9 and the ferromagnetic structure 4 to avoid electric leakage when the conductive sheet 9 is in a connected state with the PIN pin 8. Specifically, the moving piece 11 can be directly made of insulating material, or an insulating material can be sleeved on the outer periphery of the moving piece 11.

[0104] In a specific use process, in a de-energized state, the electromagnet 10 has no magnetism, and under the elastic force of the return spring 2, the moving piece 11 moves to a position abutting against the fixed support 5, at this time, as shown in Figure 2 , the conductive sheet 9 is electrically connected with the PIN pin, at this time, the heatproof plug-pull is released; in an electrically connected state, as shown in Figure 3 , the electromagnet 10 in the adjacent heatproof plug-pull electronic module attracts the moving piece 11, and the magnetic force generated on the moving piece 11 is greater than the elastic force of the return spring 2, under the action of the magnetic force, the moving piece 11 moves away from the electromagnet 10, and is inserted into the insertion hole 101 of the adjacent module housing 1 from the module housing 1, at this time, the heatproof plug-pull electronic module is in a heatproof plug-pull state; in an electrically connected state, as shown in Figure 4 , the moving piece 11 cannot normally extend out of the module housing 1 due to the blockage of the module housing 1, at this time, the conductive sheet 9 is electrically connected with the PIN pin, and the early warning assembly 121 sends early warning information.

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

[0106] In the energized state, when the moving part 11 is a permanent magnet, the electromagnet 10 in the same heatproof plug-in electronic module is arranged to be of the same polarity as the moving part 11, and the electromagnet 10 in the adjacent heatproof plug-in electronic module is arranged to be of the opposite polarity as the moving part 11. Figure 3 The adjacent heatproof plug-in electronic module refers to the adjacent heatproof plug-in electronic module close to the moving part 11.

[0107] In addition to the structure of the conductive sheet 9 and the PIN pin 8, the micro switch can also be of other structures, which is determined according to actual conditions and will not be described here.

[0108] Further, in order to smoothly insert the moving part 11 into the insertion hole 101 of the adjacent mold shell, the end of the moving part 11 extending out of the module shell 1 is provided with a ferromagnetic structure 4, which is used to cooperate with the electromagnet 10 in the adjacent heatproof plug-in electronic module to attract and hold, so that the insertion and cooperation between the moving part 11 and the adjacent mold shell is more reliable in the heatproof plug-in state.

[0109] In an embodiment, the control assembly 122 can further include a first detection part and a second detection part, the first detection part is used to detect whether the switching device 13 is located at the first position, and the second detection part is used to detect whether the switching device 13 is located at the second position, both the first detection part and the second detection part are connected with the control assembly 122.

[0110] The first detection part and the second detection part can be position sensors. In the process of 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 part 11 moves to the position abutting against the fixed support 5, at this time, the switching device 13 moves to the first position, the first detection part detects that the switching device 13 is located at the first position, and the heatproof plug-in is released; in the electrically connected state, the electromagnet 10 in the adjacent heatproof plug-in electronic module attracts the moving part 11, and the magnetic force generated by 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 in the heatproof plug-in electronic module, and the moving part 11 extends out of the module shell 1 and is inserted into the insertion hole 101 of the adjacent module shell 1, the second detection part detects that the switching device 13 is located at the second position, at this time, the heatproof plug-in electronic module is in the heatproof plug-in state; in the electrically connected state, the moving part 11 cannot normally extend out of the module shell 1 due to the blockage of the module shell 1, the second detection part cannot detect the switching device 13, and the early warning assembly 121 sends early warning information.

[0111] The electromagnet 10 mentioned in the above embodiment can be magnetized in the power-on state and lose magnetism in the power-off state, or can lose magnetism in the power-on state and lose the attraction to the moving part 11, so that the moving part 11 moves to the second position under the action of the return spring 2, and the electromagnet 10 has magnetism in the power-off state and generates an attractive force to the moving part 11, so that the moving part 11 moves to the first position against the elastic force of the return spring 2.

[0112] In addition to the above anti-hot-plug electronic module, the specific embodiment also provides an electronic device comprising at least one anti-hot-plug electronic module.

[0113] When the electronic device only comprises one anti-hot-plug electronic module, the switching device 13 can be clamped with the shell of the adjacent other device or the shell of the electronic device when the switching device 13 is in the second position, which is determined according to the actual situation.

[0114] When the electronic device comprises a plurality of anti-hot-plug electronic modules, the structures of the anti-hot-plug electronic modules can be the same to facilitate processing.
