Description

Technical Field

[0001] The present invention relates to the field of surge protection, and in particular to a decoupling module and a surge protector. Background Art

[0002] A surge, also known as transient overvoltage or overcurrent, occurs in electrical systems. It's a brief fluctuation in current or voltage. Almost all electrical equipment and devices experience surges and are also susceptible to their harmful effects. To minimize the damage caused by surges, protective components that limit overvoltage and discharge surge current are required. These components provide safety protection for electrical equipment and devices.

[0003] The surge protection components in the prior art have at least the following problems:

[0004] 1. Using a gas discharge tube (GDT) as a surge protection component. This method has a long response time during the inherent discharge process, resulting in a high discharge voltage before the actual discharge phase. This makes it difficult to meet the protection requirements of electrical equipment with voltage-sensitive components.

[0005] 2. Use a discharge tube and a transient voltage suppressor (TVS) as surge protection components. A decoupling element is placed between the discharge tube and TVS to balance their time response characteristics and discharge voltage. This decoupling element is typically a resistor or inductor. With this approach, if the decoupling element degrades or becomes overloaded, it can potentially cause signal transmission interruption in the surge protector and even fire. Summary of the Invention

[0006] In view of the above problems, the present invention provides a decoupling module with a self-protection function, and also provides a surge protector equipped with the decoupling module.

[0007] A technical means adopted by the present invention is to provide a decoupling module, comprising:

[0008] Decoupling elements; and

[0009] The switch unit is configured to short-circuit the decoupling element or not short-circuit the decoupling element.

[0010] Another technical means adopted by the present invention is to provide a surge protector, comprising:

[0011] a transient diode connected in parallel between the first circuit and the second circuit;

[0012] a discharge tube connected in parallel between the first circuit and the second circuit; and

[0013] The decoupling module; one end of the decoupling element is connected to the transient diode, and the other end is connected to the discharge tube.

[0014] Due to the adoption of the above technical solution, the decoupling module and surge protector provided by the present invention have a self-protection function, which can effectively avoid the risks of interruption of surge protector signal transmission and fire caused by degradation or overload of the decoupling element.

[0026] In order to make the invention objectives, technical solutions and technical effects of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are only for the purpose of explaining the present invention and are not intended to limit the present invention. In the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0027] The present invention provides a decoupling module 3. In one embodiment, Figure 1 and Figure 2 As shown, the decoupling module 3 may include: a decoupling element 31 and a switch unit 32; the switch unit 32 is configured to short-circuit or not short-circuit the decoupling element 31. The decoupling element 31 may be a resistor, such as a metal oxide resistor, a graphite resistor, etc., and the switch unit 32 may be a component with open and closed working states. The decoupling module 3 of this embodiment can short-circuit the decoupling element 31 when the decoupling element 31 is abnormal, overloaded, overheated, degraded, etc., thereby realizing the self-protection function of the decoupling module 3, effectively avoiding the problem of surge protection failure, and preventing the risk of fire caused by continuous heat generation. The decoupling element 31 can realize on-load short-circuit switching and seamless signal transmission, so that no line signal interruption occurs, avoiding the impact on the signal transmission of the protected line.

[0028] In one embodiment, Figure 1 and Figure 2As shown, when the decoupling element 31 is in the first state, the switch unit 32 may not short-circuit the decoupling element 31; when the decoupling element 31 is in the second state, the switch unit 32 may short-circuit the decoupling element 31. The decoupling element 31 is configured in the surge protector. The first state may mean that the decoupling element 31 is in a normal state. When the surge protector is in a normal state, the decoupling element 31 is in a normal state. The second state may mean that the decoupling element 31 is in an overloaded state. When the surge protector is in a degraded state, the decoupling element 31 is in an overloaded state. When the decoupling element 31 is in a normal state, it is not short-circuited by the switch unit 32, and the signal flows through the decoupling element 31. When the decoupling element 31 is in an overload state, it is short-circuited by the switch unit 32, and the signal flows through the switch unit 32, thereby completing a seamless conversion of the signal circuit. The decoupling element 31 gradually cools to the ambient temperature due to the lack of energy input, thereby avoiding the risks of fire or signal electrical failure.

[0029] In one embodiment, reference Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the switch portion 32 may include a conductive connection component 321 and an insulating component 322. The conductive connection component 321 may be electrically connected to the first end of the decoupling element 31 and electrically connected to or isolated from the second end of the decoupling element 31. The insulating component 322 may electrically isolate the conductive connection component 321 from the second end of the decoupling element 31, in which case the conductive connection component 321 does not short-circuit the decoupling element 31. The insulating component 322 may also electrically connect the conductive connection component 321 to the second end of the decoupling element 31, in which case the conductive connection component 321 short-circuits the decoupling element 31. Furthermore, the conductive connection component 321 may be made of a resilient metal material, such as phosphor bronze or beryllium copper, although other resilient metal materials may also be used. To ensure a better electrical connection, the conductive connection component 321 may preferably be plated with gold or nickel. However, any other conductive connection component may be used as the conductive connection component 321. Furthermore, the conductive connection component 321 may include a fixed end 321A and an elastic end 321B. The fixed end 321A of the conductive connection component 321 may be electrically connected to the first end of the decoupling element 31, and the elastic end 321B of the conductive connection component 321 may be electrically connected to or electrically isolated from the second end of the decoupling element 31. Furthermore, the decoupling module 3 may also include a circuit board 36 for mounting the decoupling element 31. The fixed end 321A of the conductive connection component 321 may be soldered to the circuit board 36. For example, the fixed end 321A may be soldered to a pad on the circuit board 36. The pad connected to the fixed end 321A is electrically connected to the first end of the decoupling element 31 via wiring on the circuit board 36.

[0030] In one embodiment, reference Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the decoupling module 3 may further include: a first conductive member 33, which is used to be electrically connected to the second end of the decoupling element 31; when the decoupling element 31 is in the first state, the conductive connection component 321 and the first conductive member 33 are electrically isolated by the insulating component 322.

[0031] For example, the decoupling module 3 of this embodiment may further include a circuit board 36 for mounting the decoupling element 31. The first conductive member 33 may be a wiring pattern, a solder pad, or the like on the circuit board 36 that is electrically connected to the second end of the decoupling element 31. Alternatively, the first conductive member 33 may be another conductive component capable of electrically connecting to the second end of the decoupling element 31. When the first conductive member 33 is a solder pad configured on the circuit board 36, the first conductive member 33 may be electrically connected to the second end of the decoupling element 31 via wiring on the circuit board 36, such as copper foil. Furthermore, the conductive connecting member 321 may include a fixed end 321A and an elastic end 321B. The fixed end 321A of the conductive connecting member 321 may be electrically connected to the first end of the decoupling element 31, while the elastic end 321B of the conductive connecting member 321 may be electrically connected to or isolated from the second end of the decoupling element 31. When the decoupling element 31 is in the first state, the insulating component 322 insulates the elastic end 321B of the conductive connection component 321 from the first conductive member 33 serving as a pad. When the decoupling element 31 is in the second state, the insulating component 322 moves away from the position where the conductive connection component 321 and the first conductive member 33 were previously insulated. The elastic end 321B of the conductive connection component 321 is in direct contact with the first conductive member 33 serving as a pad, and the conductive connection component 321 short-circuits the decoupling element 31.

[0032] In one embodiment, reference Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, when the decoupling element 31 changes from the first state to the second state, the insulating component 322 may move.

[0033] In one embodiment, reference Figure 5 、 Figure 8 and Figure 9 As shown, when the decoupling element 31 changes from the first state to the second state, the insulating component 322 can be removed from between the conductive connecting component 321 and the first conductive member 33 .

[0034] In one embodiment, reference Figure 5 、 Figure 8 and Figure 9As shown, the insulating component 322 may include an insulating plate 322A and an opening 322B. When the decoupling element 31 is in the first state, the insulating plate 322A is positioned between the conductive connection component 321 and the first conductive member 33. When the decoupling element 31 is in the second state, the opening 322B is positioned between the conductive connection component 321 and the first conductive member 33. Furthermore, the insulating component 322 may be made of similar insulating materials such as engineering plastics, epoxy board, and PET.

[0035] In one embodiment, reference Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, the switch portion 32 may further include: a positioning component and a sensing component; the positioning component is connected to the insulating component 322 and is used to position the insulating component 322; the sensing component is used to sense the state of the decoupling element 31 and prompt the positioning component to change the position of the insulating component 322.

[0036] In one embodiment, reference Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, the positioning component may include: a first positioning component and a second positioning component; the first positioning component is used to apply a first force to the insulating component 322, and can change the magnitude of the first force by adjusting its own telescopic state; the second positioning component is used to apply a second force to the insulating component 322, and the second force is opposite to the direction of the first force; the second positioning component can be deformed under the action of the sensing component, thereby changing the magnitude of the second force.

[0037] In one embodiment, reference Figure 3 、 Figure 6 、 Figure 7 and Figure 9 As shown, the first positioning member may include an elastic element 323 connected to the insulating member 322 at one end, with the other end of the elastic element 323 secured by the support frame 4. The insulating member 322 may be provided with a connection hole 322C for the elastic element 323 to connect to. The elastic element 323 may be a tension spring, or other elastic elements 323 capable of being fixed at one end and providing tension at the other end may also be used. When the second positioning member releases its securing of the insulating member 322, the insulating member 322, acting as the first positioning member, moves from a position corresponding to the first state of the decoupling member 31, i.e., the normal operating condition, to a position corresponding to the second state of the decoupling member 31, i.e., the overload operating condition.

[0038] In one embodiment, reference Figure 4 and Figure 7 As shown, the sensing component may include a thermal sensing element 325 in thermal contact with the decoupling element 31. The thermal sensing element 325 secures the second positioning member when the decoupling element 31 is in a first state, and does not secure the second positioning member when the decoupling element 31 is in a second state. The thermal sensing element 325 enables thermal monitoring and response of the decoupling element 31.

[0039] In one embodiment, reference Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, the second positioning member may include a flexible wire 324; the insulating member 322 may be provided with a positioning buckle 322D for passing the flexible wire 324; and the thermal sensing element 325 may include a low-temperature solder point. The thermal sensing element 325 is in thermal conductive contact with the decoupling element 31, and heat from the decoupling element 31 can be transferred to the thermal sensing element 325.

[0040] In this embodiment, there are various options for specific heat conduction methods and specific selections for the thermal sensing element 325. For example, the thermal sensing element 325 may be in contact with the decoupling element 31 via a heat conduction component, or the thermal sensing element 325 may be placed in the heat release area of ​​the decoupling element 31. It is sufficient that the thermal sensing element 325 can effectively sense the heat generated by the decoupling element 31. When the thermal sensing element 325 uses a low-temperature solder point, the thermal conduction contact method between the thermal sensing element 325 and the decoupling element 31 can ensure that when the decoupling element 31 is in the second state, the heat absorbed by the thermal sensing element 325 can cause the low-temperature solder point to melt.

[0041] This embodiment merely illustrates the thermal conductive contact method. For example, the decoupling module 3 may further include a circuit board 36 for mounting the decoupling element 31. The circuit board 36 may be provided with a soldering pad for soldering the flexible wire 324. Specifically, the flexible wire 324, serving as the second positioning member, may have one end soldered to the soldering pad, then pass through a positioning clip 322D provided on the insulating component 322, and finally soldered to the low-temperature solder point. If there are multiple decoupling elements 31, multiple low-temperature solder points serving as the thermal sensing elements 325 may also be provided. For example, each decoupling element 31 may correspond to a thermal sensing element 325. The flexible wire 324, serving as the second positioning member, may then be soldered to each of the low-temperature solder points in sequence. When any of the low-temperature solder points melts, the flexible wire 324 passing through the positioning clip 322D will change position, thereby causing the insulating component 322 to move. Furthermore, the flexible wire 324 may also serve as a signal transmission function, such as transmitting a remote alarm signal. The flexible conductor 324 may be a flexible metal wire, such as copper wire, tinned copper wire, enameled wire, or other metal conductor material with good flexibility.

[0042] In this embodiment, the decoupling element 31 can be soldered to the circuit board 36. The pin soldering points 311 of the decoupling element 31 and the low-temperature soldering points can be located on the front and back sides of the circuit board 36, respectively, and in corresponding positions. That is, the pin soldering points 311 of the decoupling element 31 and the low-temperature soldering points are arranged back-to-back on the front and back sides of the circuit board 36. Furthermore, the melting point of the solder on the pin soldering points 311 of the decoupling element 31 is higher than that of the low-temperature soldering points. This allows heat generated by the decoupling element 31 to be effectively transferred to the low-temperature soldering points serving as the thermal sensing element 325 via the pin soldering points 311 and the circuit board 36. Because the melting point of the solder on the pin soldering points 311 of the decoupling element 31 is higher than that of the low-temperature soldering points, the pin soldering points 311 of the decoupling element 31 do not melt when the low-temperature soldering points melt. The thickness of the circuit board 36 can be between 0.2 mm and 1.2 mm. The thermal sensing element 325 fixes the second positioning member when the decoupling element 31 is in the first state. For example, the flexible wire 324 serving as the second positioning member can be directly soldered to the low-temperature solder point of the thermal sensing element 325. When the decoupling element 31 is in the first state, the low-temperature solder point does not melt, so the flexible wire 324 serving as the second positioning member is fixed. When the decoupling element 31 is in the second state, the low-temperature solder point absorbs the heat of the decoupling element 31 and melts, so the flexible wire 324 serving as the second positioning member is loosened and fixed.

[0043] When the decoupling element 31 is in the first state, the flexible wire 324 serving as the second positioning member is in a taut state due to the force exerted by the insulating component 322 of the first positioning member and the low-temperature solder point of the thermal sensing element 325. When the decoupling element 31 is in the second state, the flexible wire 324 serving as the second positioning member is in a loose state after losing the constraint of the thermal sensing element 325, thereby releasing the insulating component 322.

[0044] In one embodiment, reference Figure 10 、 Figure 11 and Figure 12 As shown, the decoupling module 3 may further include a state indicator for indicating the state of the decoupling element 31. When the decoupling element 31 is in a first state, the state indicator displays a first color, and when the decoupling element 31 is in a second state, the state indicator displays a second color. Preferably, the first color may be green, and the second color may be red.

[0045] In one embodiment, reference Figure 10 、 Figure 11 and Figure 12 As shown, the status indicator may include a first color display area 341 and a status indicator sheet 342. The first color display area 341 is provided on the side wall of the carrier 4 and is configured to display a first color. The status indicator sheet 342 includes a second color display area 343 configured to display a second color. When the insulating component 322 moves, the status indicator sheet 342 moves and covers the first color display area 341. When there are multiple decoupling elements 31, any one of the decoupling elements 31 in the second state can drive the status indicator sheet 342 to change state.

[0046] For example, refer to Figure 10 As shown, further, a positioning hole 342A is opened on the status indicator piece 342, referring to Figure 11 and Figure 12 As shown, the carrier 4 is provided with a support member 41 adapted to connect with the positioning hole 342A, and the status indicator piece 342 is movably connected to the carrier 4 by utilizing the positioning hole 342A and the support member 41. Figure 6As shown, the status indicator sheet 342 is arranged in contact with the insulating component 322. After the insulating component 322 moves, the status indicator sheet 342 is supported by the insulating component 322, thereby overcoming the elastic force of the carrier 4 and displacing to cover the first color display area 341. Furthermore, the positioning hole 342A can be a circular hole or a rectangular hole. Furthermore, the status indicator sheet 342 can be made of a flexible circuit board, PET (polyester resin) flexible material, etc. Through this embodiment, it is possible to configure the decoupling element 31 and the applicable surge protector with a short-circuit switching module with a degradation indication function, thereby being able to accurately monitor the working condition of the decoupling module 3.

[0047] In one embodiment, reference Figure 1 、 Figure 2 and Figure 13 As shown, the decoupling module 3 may further include: a remote signaling alarm unit 35, which is used to perform a remote signaling alarm when the decoupling element 31 is in the second state. This embodiment can realize the remote alarm function of the decoupling module 3. Figure 1 and Figure 2 As shown, the remote signal alarm unit 35 can be an alarm switch connected to the switch unit 32. The alarm switch is closed when the decoupling element 31 is in the first state and is open when the decoupling element 31 is in the second state. The decoupling module 3 can include multiple decoupling elements 31. If any decoupling element 31 has an abnormality, a remote signal alarm can be issued. Figure 13 As shown, two remote signaling alarm terminals of the alarm switch are shown, namely the first remote signaling alarm terminal 351 and the second remote signaling alarm terminal 352.

[0048] In one embodiment, reference Figure 1 、 Figure 2 、 Figure 5 and Figure 8As shown, there can be two decoupling elements 31, each corresponding to a conductive connection component 321. The conductive connection components 321 of each decoupling element 31 share a common insulating component 322. Each decoupling element 31 can also correspond to a thermal sensing element 325, and each decoupling element 31 can share a first positioning member and a second positioning member. Specifically, for example, when any decoupling element 31 experiences an overload, the generated heat can be transferred to the same second positioning member via its respective thermal sensing element 325. Upon heating, the thermal sensing element 325 releases its fixation on the second positioning member, causing the second positioning member to become loose, further releasing the displacement restriction of the insulating component 322, which serves as an intermediate conversion medium. That is, when there are multiple decoupling elements 31, they can share a set of first positioning members, second positioning members, and insulating component 322, and each decoupling element 31 can be configured with a corresponding conductive connection component 321 and thermal sensing element 325.

[0049] refer to Figure 1 As shown, the decoupling module 3 is applied to a line to be protected, which includes a first line 8 and a second line 9. The decoupling module 3 includes two decoupling elements 31, one disposed in the first line 8 and the other in the second line 9. The two ends of the decoupling element 31 disposed in the first line 8 are connected to the first end of the discharge tube 2 and the first end of the transient diode 1, respectively. The two ends of the decoupling element 31 disposed in the second line 9 are connected to the second end of the discharge tube 2 and the second end of the transient diode 1, respectively. Corresponding to the number of decoupling elements 31, there are also two conductive connecting components 321.

[0050] refer to Figure 2 As shown, the decoupling module 3 can also be applied to two lines to be protected. Of course, the decoupling module 3 can also be applied to more than two lines to be protected. In actual application, the decoupling module 3 can be configured according to user needs.

[0051] The present invention also provides a surge protector. In one embodiment, referring to Figures 1 to 15As shown, the surge protector may include: a transient diode 1, a discharge tube 2, and a decoupling module 3 as described in any of the above embodiments; the transient diode 1 is connected in parallel between a first line 8 and a second line 9; the discharge tube 2 is connected in parallel between the first line 8 and the second line 9; and a decoupling element 31 is connected at one end to the transient diode 1 and at the other end to the discharge tube 2. In this embodiment, the discharge tube 2 constitutes a coarse protection unit, and the transient diode 1 constitutes a fine protection unit. The discharge tube 2, transient diode 1, and decoupling module 3 together constitute a surge protection structure combining the coarse and fine protection units. The transient diode 1 in this embodiment may also be replaced by a combination of a transient diode 1 and a diode. The discharge tube 2 may be a triode discharge tube 2. The first line 8 and the second line 9 may be signal transmission lines. For example, the first line 8 may be a signal input line, and the second line 9 may be a signal output line.

[0052] The surge protector described in this embodiment can be applied to circuits requiring surge protection, such as signal transmission lines and other circuits requiring signal protection. The components of the surge protector can be integrated into a monolithic structure and installed on signal lines, electrical equipment, and devices to provide good safety protection.

[0053] In one embodiment, reference Figures 1 to 15 As shown, the surge protector may further include: a carrier 4 and a housing 5. The carrier 4 is configured to support the transient diode 1, the discharge tube 2, and the decoupling module 3; the housing 5 is configured to accommodate the surge protector; and the housing 5 is provided with a window 51. The window 51 may be configured to display a color indicating the status of the decoupling element 31, for example, by exposing a first color display area 341 provided on the sidewall of the carrier 4 or a second color display area 343 provided on the status indicator sheet 342. When the decoupling element 31 transitions from the first state to the second state, the color displayed in the window 51 switches from the first color to the second color, for example, from green to red, thereby providing a degradation indication warning and facilitating determination of the operating status of the decoupling element 31.

[0054] In this embodiment, at least one surge protector can be housed within the housing 5. If there are multiple surge protectors, they can be arranged in a row within the housing 5. Each surge protector can be configured with an input terminal 10 and an output terminal 11 for connecting to a circuit requiring surge protection. Furthermore, the input terminal 10 and the output terminal 11 can utilize a push-in connection method using spring 72 connection technology as wiring terminals, allowing for quick wiring and reducing installation and maintenance costs.

[0055] In one embodiment, reference Figure 14 and Figure 15 As shown, the housing 5 has a mounting surface 52; the surge protector may further include: a grounding electrode 6 and a detachable connection structure, the grounding electrode 6 being arranged on the mounting surface 52; the detachable connection structure being arranged on the mounting surface 52 for installing the surge protector. Furthermore, the detachable connection structure includes: a locking plate 71 and a spring 72 connected to the locking plate 71. Furthermore, the detachable connection structure can be engaged with and installed with an external sliding rail, specifically, the locking plate 71 can lock the external sliding rail under the elastic force of the spring 72; the external sliding rail can be a TH35 type guide rail or other types of guide rails. The grounding electrode 6 is used for grounding the entire surge protector and can be made of an elastic material.
