Description

Technical Field

[0001] This utility model relates to the field of shielding doors for electromagnetic shielding rooms, and more particularly to a shielding door for electromagnetic shielding rooms with an emergency switch. Background Technology

[0002] Electromagnetic shielding rooms are used to isolate indoor and outdoor electromagnetic environments. They can prevent external electromagnetic interference from entering the room and affecting the testing and operation of indoor equipment, and limit electromagnetic leakage from high-power, high-frequency equipment inside the room to prevent it from affecting the normal operation of surrounding equipment. They are ideal sites for EMC testing or confidential equipment rooms.

[0003] To meet the above requirements, the shielding doors used in electromagnetic shielding rooms must have excellent electromagnetic shielding capabilities. Reliability must be considered during the design phase, and electromagnetic shielding must also be taken into account. Existing electromagnetic shielding room doors are generally equipped with manual and automatic emergency switches to handle special situations, such as fires. Automatic emergency switches are mainly used when power is still available, while manual emergency switches are mainly used when power is unavailable.

[0004] Known automatic emergency switches are generally push-button structures, such as... Figure 1 As shown. To enable simultaneous control of the electromagnetic shielding door's opening from both inside and outside the electromagnetic shielding room, two switches are typically installed, such as... Figure 1 a and b are installed on the shielded door 100, with one set facing the electromagnetic shielding room and the other facing the electromagnetic shielding room. In special circumstances, by pressing the emergency switch inside or outside, an emergency signal is sent, and the emergency motor is used to open the door.

[0005] However, as Figure 1 The structure uses two switching devices, which requires consideration of magnetic leakage issues when installing them on the platform screen door, making installation difficult. At the same time, the use of two switching devices increases the possibility of failure, and the consequences of a failure of the switching devices would be unimaginable.

[0006] The purpose of this invention is to provide an emergency switch assembly and a shielding door for an electromagnetic shielding room that have good shielding effect and low failure rate. Utility Model Content

[0052] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0053] This application provides one embodiment:

[0054] like Figure 2 An emergency switch assembly includes: a triggering mechanism 1 and at least two drive mechanisms 2; wherein the drive mechanisms 2 are disposed on both sides of the triggering mechanism 1 and are arranged opposite to each other, for issuing an emergency signal when any of the drive mechanisms 2 is electrically connected to the triggering mechanism 1.

[0055] Preferably, the triggering mechanism 1 is positioned directly opposite the door, allowing the operator to press it from both inside and outside the shielding door.

[0056] Specifically, such as Figure 3 The triggering mechanism 1 includes a housing 101, a contact 102, and a terminal group 103. The contact 102 is detachably disposed within the housing 101. The terminal group 103 is disposed on the contact 102 and is used to electrically connect the terminal group 103 and issue an emergency signal when the driving mechanism 2 contacts the contact 102. Preferably, the terminal group 103 has a hexagonal cross-section with external threads for easy shielding of battery waves. The housing 101 is a metal housing for electromagnetic shielding. Furthermore, the housing 101 has through holes corresponding to the terminal group 103, and the terminal group 103 is fixed to the housing 101 using nuts, thereby fixing the contact body 1021.

[0057] Furthermore, such as Figure 3The contact 102 includes: a contact body 1021, two copper-plated areas 1022, and one isolation area 1023; wherein the copper-plated areas 1022 are disposed on the contact body 1021; the isolation area 1023 is disposed between any two adjacent copper-plated areas 1022; the output end of the drive mechanism 2 faces the corresponding isolation area 1023; preferably, the contact body 1021 is flat, and its area is selected according to the actual situation. The contact body 1021 can be made of glass fiber reinforced epoxy resin, which is a non-magnetic material to ensure electromagnetic shielding. The terminal group 103 includes a positive terminal and a negative terminal, which are respectively disposed on the two copper-plated areas 1022. When the two copper-plated areas 1022 are conductive, electrical conduction can be achieved to complete emergency signal acquisition. In order to fix the contact body 1021 and simplify the structure, the terminal group 103 is provided with an insulating layer on the outside. One end of the terminal group 103 is welded to the contact 102 to maintain electrical continuity, and the other end is connected to a signal acquisition unit, such as a microcontroller, through a wire.

[0058] In order to collect emergency signals, such as Figure 3 Specifically, the driving mechanism 2 includes: a base plate 201, a button module 202, an active module 203, and a guide member 204; wherein, the button module 202 is disposed on the base plate 201 and is used for linear movement after being subjected to force; the active module 203 is disposed on the button module 202 and is used to follow the linear movement of the button module 202; the guide member 204 is disposed between the trigger mechanism 1 and the base plate 201 and is used to guide the movement of the active module 203 and provide electromagnetic shielding; the end of the active module 203 faces the trigger mechanism 1 and is used to electrically connect with the trigger mechanism 1 after the active module 203 moves linearly, thereby emitting an emergency signal; wherein, one end of the guide member 204 is connected to the base plate 201, such as by pasting, and the other end contacts the contact body 1021. In this embodiment, the guide member 204 is made of a non-metallic material, such as plastic, which ensures strength while also shielding electromagnetic waves; the guide member 204 is a hollow part with a hexagonal shape. Meanwhile, a connecting post 20A is provided between the housing 101 and the base plate 201 to fix the housing 201.

[0059] Preferred, such as Figure 4 The button module 202 includes: a fixing base 2021 fixed on the base plate 201; one end of the connector 2022 is threaded through the outside of the fixing base 2021, and the other end of the connector 2022 is set with the button cap 2023; a reset spring 2024 is provided between the button cap 2023 and the base plate 201; when pressed by external force, the button cap 2023 moves linearly along the connector 2022 to compress the spring 2024, and resets itself after reaching the position.

[0060] Furthermore, such as Figure 5The active module 203 includes: a guide post 2031 and a contact 2032; wherein, one end of the guide post 2031 is connected to the inner side of the button cap 2023 in the button module 202; the contact 2032 is disposed at the other end of the guide post 2031; the contact 2032 is a metal part for conducting electricity; the contact 2032 is facing the trigger mechanism 1 and is used to electrically connect with the trigger mechanism 1 after the active module 203 moves linearly.

[0061] The contact element 2032, such as Figure 6 It includes: a contact body 20321 and two protrusions 20322; wherein, the contact body 20321 is connected to the end of the guide post 2031; the protrusions 20322 are disposed on the outer extension of the contact body 20321 and are disposed towards the trigger mechanism 1; preferably, the cross-section of the guide post 2031 is hexagonal, and the guide post 2031 is made of a non-magnetic non-metallic material, such as plastic.

[0062] In this embodiment, due to the relatively concealed location and humid environment of the electromagnetic shielding room, coupled with the special application scenario of the emergency switch, the emergency switch is not a commonly used device and its operating conditions are harsh. If existing switch components are used, most adopt a structure of metal spring contact for energization. Under prolonged disuse, the metal carbon sheet is prone to rusting, which can easily lead to ineffective pressing in special circumstances, resulting in serious accidents. In this embodiment, the protrusion 20322 can be positioned directly above the isolation area 1023. When moving downwards, it connects the two copper-plated areas 1022, realizing the acquisition of emergency signals. Moreover, due to the presence of the housing 101, there is no dust or corrosion in the copper-plated areas 1022, ensuring reliable contact between the protrusion 20322 and the copper-plated areas 1022. Even if the spring 2024 rusts, it will not affect the contact between the protrusion 20322 and the copper-plated areas 1022, ensuring reliable acquisition of emergency signals. Specific Implementation

[0063] This application also provides an embodiment:

[0064] In Specific Embodiment 1, since the two triggering mechanisms 1 are set facing each other, the relative height of the triggering mechanisms 1 inside and outside the electromagnetic shielding door is the same. However, in actual use, for waterproofing or other considerations, the inside of the shielding room is higher than the outside. If the relative height of the triggering mechanisms 1 inside and outside the electromagnetic shielding door is the same, the height of the triggering mechanisms 1 inside the shielding room will be too low. In order to solve this problem, based on Specific Embodiment 1, it is necessary to adjust the position of the triggering mechanisms 1.

[0065] In this embodiment, as Figure 7The two drive mechanisms 2 are staggered for ease of use by the user. Specific Implementation

[0066] This application also provides an embodiment:

[0067] like Figure 8 A shielding door for an electromagnetic shielding room includes: a shielding door body 100 and an emergency switch assembly as described in specific embodiment 1 or 2. Figure 8 Only the structure in Specific Embodiment 2 is used; the emergency switch assembly is set on the shielding door body 100; the triggering mechanism 1 in the emergency switch assembly is located inside the shielding door body 100, forming an electromagnetic shielding structure.

[0068] Furthermore, the shielding door body 100 is provided with a detachable connection structure that connects to the emergency switch assembly.

[0069] Optionally, a groove is provided at the end of the base plate 201 of the drive mechanism 2 to match the shielding door body 100, as shown at point A in the figure. This structure facilitates disassembly and installation, and also allows shielding cotton to be placed on the contact surface between the shielding door body 100 and the base plate 201 to ensure the shielding effect.

[0070] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions made by those skilled in the art within the technical scope disclosed in this utility model are all within the protection scope of this utility model. Therefore, the protection scope of this utility model is determined by the scope of the claims.
