Description

Technical Field

[0001] The present disclosure relates to the field of electrical devices, and more particularly to surge protectors. Background Art

[0002] A surge protector (also called a lightning arrester) is an electronic device that can provide safety protection for lines including electronic devices. When a sudden current or voltage is suddenly generated in the circuit due to external interference, the surge protector can enable the branch including the shunt to be turned on in a very short time, thereby preventing the surge from damaging the electronic equipment.

[0003] In order to realize the above functions, the existing surge protector usually needs many parts, which makes the overall structure of the surge protector more complicated, which is not only costly but also has poor reliability. Utility Model Content

[0004] It is desirable to provide a surge protector that can be assembled quickly, and it is desirable to improve the replacement efficiency of some components in the surge protector.

[0005] At least to overcome the problems existing in the existing surge protector and / or other potential problems, exemplary embodiments of the present disclosure provide a surge protector and a circuit system using the surge protector.

[0006] According to a first aspect of the present disclosure, a surge protector is provided, comprising: one or more core components and a base. The base comprises a first connection portion having a groove and a second connection portion having a groove. The one or more core components each comprise: a first coupling member and a second coupling member. The first end of the first coupling member is configured to be mechanically and electrically connected to the first connection portion of the base. The first end of the second coupling member is configured to be mechanically and electrically connected to the second connection portion of the base. The first end of the first coupling member comprises a first portion capable of elastic deformation. The first end of the second coupling member comprises a second portion capable of elastic deformation.

[0007] The surge protector provided by the present disclosure allows components that play a key role in surge protection to be modularized, for example, so that the core assembly can be quickly installed on the base. The elastically deformable portions of the first and second coupling members can be used to ensure the reliability of the electrical and mechanical connections. In addition, the core assembly provided also enables it to be replaced as a whole, thereby improving maintenance efficiency.

[0008] Another benefit of the modular core assembly is that the number of core assemblies to be used can be determined according to the scenario of the circuit, and the core assembly can be quickly installed on the base. For example, in the case of three-phase electricity, three core assemblies can be used for each phase of the three-phase electricity, and optionally, another core assembly can be provided for the neutral line. In other cases, there can be one, two or more core assemblies to be respectively applicable to surge protection of single-phase, two-phase or more-phase circuits.

[0009] According to some embodiments, the one or more core components include a circuit device. The second end of the first coupling member is mechanically and electrically connected to an input side of the circuit device, and the second end of the second coupling member is mechanically and electrically connected to an output side of the circuit device.

[0010] According to some embodiments, the first connection portion has a plurality of grooves, each of which corresponds to a first coupling member in a core component.

[0011] According to some embodiments, the surge protector further comprises a housing. The housing comprises a pressing portion. The pressing portion is disposed on a side of the housing. The pressing portion can be actuated to deflect from a first position to a second position relative to a top side of the housing. At the first position, the pressing portion can engage a groove on the base, and at the second position, the pressing portion is separated from the groove on the base.

[0012] According to some embodiments, the circuit arrangement comprises a nonlinear component. The nonlinear component may be selected from the group consisting of: a varistor, a gas discharge tube or a discharge gap.

[0013] According to some embodiments, the first portion is configured to be biased against one side of the groove of the first connection portion. The first end of the second coupling member includes a second portion that is elastically deformable and configured to be biased against one side of the groove of the second connection portion.

[0014] According to some embodiments, the first portion includes a flat portion and an arcuate portion, the flat portion extends from the arcuate portion, and the elasticity of the arcuate portion is arranged to deform the flat portion against one side of the groove of the first connecting part until the flat portion completely contacts one side of the groove.

[0015] According to some embodiments, the second portion includes a flat portion and an arcuate portion, the flat portion extends from the arcuate portion, and the elasticity of the arcuate portion is arranged to deform the flat portion against one side of the groove of the second connecting part until the flat portion completely contacts one side of the groove.

[0016] According to some embodiments, corresponding first coupling members of one or more core assemblies are connected to the first connection portion.

[0017] According to some embodiments, the number of the second connection portions corresponds to the number of the core assemblies, and each of the second connection portions corresponds to the second coupling member of one core assembly.

[0018] According to a second aspect of the present disclosure, a circuit system is provided. The circuit system includes: a load; and a branch connected in parallel with the load. The branch includes a surge protector provided according to the first aspect of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 1 A surge protector 1000 according to the present disclosure is shown, which is suitable for protecting a line using three-phase electricity as a voltage source. Fig.15 A schematic diagram of a circuit system including a surge protector provided according to the present disclosure is shown. The circuit system includes a load 2000 and a branch connected in parallel with the load 2000. The branch includes a surge protector 1000.

[0039] The surge protector 1000 includes core components 100A, 100B, 100C, and 100N. The core components 100A, 100B, and 100C correspond to one phase of three-phase electricity, respectively, and the core component 100N corresponds to a neutral line of the three-phase electricity.

[0040] Figure 2 An example of a core assembly 100A provided by the present disclosure is shown. Figure 2 The core assembly 100A includes a housing 1. The housing has a pressing portion 11. The pressing portion 11 is disposed on a side surface 12 of the housing 1. The pressing portion 11 may include an anti-slip portion 112 having a corrugated shape of crests and valleys. The anti-slip portion 112 is used to increase the friction coefficient when a finger contacts the pressing portion. The pressing portion 11 also includes a protruding portion 111. The function of the protruding portion 111 will be described in detail below. Figure 3 Give a description.

[0041] In some embodiments, core assembly 100B, core assembly 100C, and core assembly 100N may have the same combination as core assembly 2. Figure 2 The housing 1 and the pressing portion 11 are described.

[0042] Figure 3 1 shows a perspective view of the base 200 of the surge protector 1000 according to the present disclosure. Figure 3 The base 200 may include a cover 201 and a bottom portion 202. The cover 201 is disposed above the bottom portion 202 and is configured to at least partially shield the electrical components disposed between the cover 201 and the bottom portion 202, such as the following combination Fig.12 The first connecting portion 230 described above is combined with the following Fig.13 The second connection portion 240A is described.

[0043] The base 200 may further include a pair of guide portions. In some embodiments, the base 200 includes a pair of guide portions 210A and 220A, a pair of guide portions 210B and 220B, a pair of guide portions 210C and 220C, and a pair of guide portions 210D and 220D. The pair of guide portions 210A and 220A are used to guide the movement of the core assembly 100A, and the guide portions 210A and 220A may be used to define the orientation of the core assembly 100A. In some embodiments, the pair of guide portions 210A and 220A are configured to allow the core assembly 100A to be moved only in one direction. The guide portions 210A and 220A may be, for example, recessed. Figure 3 As shown, the guide portions 210A and 220A may be disposed on the cover body 201 and extend in a direction perpendicular to the bottom portion 202 .

[0044] Similar to the pair of guide portions 210A and 220A, the pair of guide portions 210B and 220B, the pair of guide portions 210C and 220C, and the pair of guide portions 210D and 220D can be used to guide the movement of the core assemblies 100B, 100C and 100N, respectively, and can be used to limit the orientation of the core assemblies 100B, 100C and 100N.

[0045] The base 200 may further include grooves 250A, 250B, 250C, and 250N. Figure 3 As shown in FIG. 1 , the grooves 250A, 250B, 250C, and 250N may include an elongated portion, and the size of the elongated portion of the grooves 250A, 250B, 250C, and 250N is defined by the guide portions 220A, 220B, 220C, and 220D, respectively. In some embodiments, the length direction of the elongated portion of the grooves 250A, 250B, 250C, and 250N is substantially perpendicular to the extension direction of the guide portions 220A, 220B, 220C, and 220D. In one example, the length of the elongated portion is equal to the width of the guide portion 220A. The depth of the groove 250A is configured so that the protrusion 111 of the pressing portion 11 can be at least partially received by the groove 250A.

[0046] In use, the protrusion 111 of the pressing portion 11 may be received by a corresponding groove 250A on the base 200 , so that the pressing portion 11 engages with the groove 250A for fixing the core assembly 100A in position relative to the base 200 .

[0047] The grooves 250B, 250C and 250N can function similarly to the groove 250A. That is, the grooves 250B, 250C and 250N can also be used to engage the pressing portions of the core components 100B, 100C and 100N (if their pressing portions are the same or similar to the pressing portion 11), and engage the protruding portions of the pressing portions (if any). For the sake of brevity, they will not be described in detail here.

[0048] Figure 4 Provided Figure 2 A perspective view of a circuit device 2a, a first coupling member 3, and a second coupling member 4 in a core assembly 100A is shown. The circuit device 2a of the core assembly 100A is accommodated inside the housing 1. The circuit device 2a may include a nonlinear component. The nonlinear component includes a varistor, a gas discharge tube, or a discharge gap. As an example, the circuit device 2a may include a varistor. Alternatively, the nonlinear component may also be a gas discharge tube, a discharge gap, or a combination thereof with a varistor.

[0049] When the voltage applied to the circuit device 2a is lower than the threshold value, the circuit device 2a is not turned on so that no or almost no current flows through the circuit device 2a. When the voltage applied to the circuit device 2a is higher than the threshold value, the circuit device 2a is turned on so that current flows through the circuit device 2a. The threshold value can be predetermined according to the parameters of the nonlinear component. The circuit devices 2b and 2c have a configuration similar to the circuit device 2a. In this regard, since the core component 100A including the circuit device 2a and the core components 100B and 100C including the circuit devices 2b and 2c similar to the circuit device 2a have similar functions and configurations, the core components 100A, 100B and 100C are also referred to as the first type of core components herein.

[0050] Continue to refer Figure 4 , the core assembly 100A further includes a first coupling member 3. The first coupling member 3 may be partially accommodated by the housing 1. That is, the first coupling member 3 may extend from the inside of the housing 1 to the outside of the housing 1. The first coupling member 3 may have a first end 31 and a second end 32. The first end 31 of the first coupling member 3 is configured to be mechanically and electrically connected to the first connection portion of the base 200, for example, as follows Fig.12 The first connection portion 230 is shown in FIG. The second end 32 of the first coupling member 3 is mechanically and electrically connected to the input side 21 of the circuit arrangement 2a.

[0051] The core assembly 100A further includes a second coupling member 4. The second coupling member 4 may be partially accommodated by the housing 1. That is, the second coupling member 4 may extend from the inside of the housing 1 to the outside of the housing 1. The second coupling member 4 may have a first end 41 and a second end 42. The first end 41 of the second coupling member 4 is configured to be mechanically and electrically connected to the second connection portion of the base 200, for example, as follows Fig.13 The second end 42 of the second coupling member 4 is mechanically and electrically connected to the output side 22 of the circuit arrangement 2a.

[0052] Figure 5 Provided Figure 4 A perspective view of the first coupling member 3 is shown. Figure 4-Figure 5, the first end 31 of the first coupling member 3 may include a first portion 310 that is elastically deformable. When the first portion 310 is squeezed by a force, the first portion 310 moves toward the body 30 of the first coupling member 3, and when the force does not exist, the elasticity of the first portion 310 enables the first portion 310 to return to an initial state. In some embodiments, the first portion 310 may include a flat portion 310-1 and an arc portion 310-2. The flat portion 310-1 may be used to contact, for example, the groove 231A of the first connection portion 230. The arc portion 310-2 may extend from the body 30. The elasticity of the arc portion 310-2 is arranged so that the flat portion 310-1 is deformed against one side 233A of the groove 231A of the first connection portion 230 until the flat portion 310-1 completely contacts one side 233A of the groove 231A. Additionally, the arc portion 310-2 may be divided into a plurality of sections for enhancing the elastic deformation capability of the first portion 310. The sections of the arc portion 310 - 2 may be separated from each other by gaps 310 - 3 .

[0053] The first portion 310 may be configured to be biased against the following Fig.12 The side 233A of the groove 231A of the first connection portion 230 is shown. In some embodiments, the arc portion 310-2 is deformed so that the flat portion 310-1 of the first portion 310 is biased against the side 233A of the groove 231A and the flat portion 310-1 is in full contact with the side 233A of the groove 231A.

[0054] Still reference Figure 4 , the first end 41 of the second coupling member 4 includes a second portion 410 that can be elastically deformed. The second portion 410 can be configured to be biased against the following Fig.13 The second connection portion 240 is shown at one side 243A of the groove 241A.

[0055] Similar to the first portion 310 of the first coupling member 3, the second portion 410 of the second coupling member 4 may include a flat portion 410-1 and an arcuate portion 410-2. The flat portion 410-1 may be used to contact, for example, the groove 241A of the second connection portion 240A. The arcuate portion 410-2 may extend from the body 40. The elasticity of the arcuate portion 410-2 is arranged so that the flat portion 410-1 is deformed against one side 243A of the groove 241A of the second connection portion 240A until the flat portion 410-1 completely contacts the one side 243A of the groove 241A. Additionally, the arcuate portion 410-2 may be divided into a plurality of sections for enhancing the elastic deformation capability of the first portion 410. The plurality of sections of the arcuate portion 410-2 may be separated from each other by gaps.

[0056] Figure 6 Provided Figure 2A plan view of core assembly 100A is shown. Figure 6 The pressing portion 11 is shown. Additionally, the core assembly 100A may further include a pressing portion 11'. The pressing portions 11, 11' are respectively provided on the side surfaces 12, 12' of the shell 1. The simultaneous provision of the pressing portions 11, 11' on the side surfaces 12, 12' of the shell 1 of the core assembly 100A makes it easier for the user to disassemble and replace the core assembly 100A. Additionally or alternatively, two side surfaces of the shells of the core assembly 100B, the core assembly 100C, and the core assembly 100N may also be provided with two pressing portions similar to the pressing portions 11, 11'.

[0057] In some embodiments, the first coupling member 3 may include a middle portion 33 in a pre-tensioned state. The pre-tensioned state of the middle portion 33 may be maintained by the connection 211 between the second end 32 of the first coupling member 3 and the input side 21. When the connection 211 is broken, the middle portion 33 is released from the pre-tensioned state and drives the second end 32 of the first coupling member 3 to move away from the input side 21. The connection 211 between the second end 32 of the first coupling member 3 and the input side 21 is formed by soldering. In some embodiments, the current flowing through the connection 211 between the first coupling member 3 and the circuit device 2a generates heat at the connection 211, and in a pre-set situation, the generated heat causes the tin to melt. The pre-set situation can be determined based on calculating the range of heat that the current can generate in contact according to the pre-calculated current size and the correlation between the melting of the tin and the current size. Since the tin is transformed from a solid to a melt and the structural strength of the connection 211 is weakened, the pre-tensioned middle portion 33 can be used to move the second end 32 away from the input side 21. With such a configuration of the first coupling element 3 , it is possible to meet the expectation that the second end 32 of the first coupling element 3 should be disconnected from the input side 21 of the circuit arrangement 2 a in a preset situation.

[0058] Figure 7 Provided Figure 2 A perspective view of a portion of a shell in a core assembly is shown, which includes a pressing portion 11, 11'. The pressing portion 11, 11' can be actuated to deflect from a first position Pos_1 to a second position Pos_2 relative to a top side 13 of the shell 1. For example, the pressing portion 11, 11' can be pressed in the direction indicated by the arrow. The actuation of the pressing portion 11, 11' can be achieved by a user. In some embodiments, the pressing portion 11, 11' can be formed integrally with the shell 1, and the pressing portion 11, 11' includes a free end of a side 12, 12' of the shell 1. In some examples, the free end can be achieved by forming a slit 120 in the side 12, 12', such as Figure 7 shown.

[0059] Figure 8A schematic diagram of the movement of the pressing part is provided. Figure 8 , the pressing portion 11 has been actuated to deflect from the first position Pos_1 to the second position Pos_2 relative to the top side 13 of the housing 1. A threshold value of the angular distance θ between the first position Pos_1 and the second position Pos_2 may be defined. The threshold value of the angular distance θ may be determined according to the material forming the pressing portion 11. In some embodiments, the threshold value of the angular distance θ may be in the range between 15 degrees and 30 degrees.

[0060] When the pressing portion 11 moves from the first position Pos_1 to the second position Pos_2, the pressing portion 11 engaging the groove (e.g., groove 250A) on the base 200 becomes separated from the groove (e.g., groove 250A) on the base 200. The pressing portion 11' may also have a similar movement process as the pressing portion 11, except that the direction in which the pressing portion 11' is actuated is opposite to that of the pressing portion 11.

[0061] Fig. 9 A perspective view of a second type of core assembly according to some embodiments of the present disclosure is provided. Similar to the first type of core assembly, the second type of core assembly 100N includes a housing 1 and pressing portions 11, 11'. The pressing portions 11, 11' are respectively disposed on the side surfaces 12, 12' of the housing 1. The pressing portions 11, 11' can be actuated to deflect from a first position Pos_1 to a second position Pos_2 relative to a top side 13 of the housing 1.

Fig. 9 and Fig.10 , the circuit device 2n is accommodated in the housing 1. The circuit device 2n may include a discharge tube. When the voltage applied to the circuit device 2n is lower than the threshold value, the circuit device 2n is not turned on so that no or almost no current flows through the circuit device 2n. When the voltage applied to the circuit device 2n is higher than the threshold value, the circuit device 2a is turned on so that current flows through the circuit device 2n.

[0063] The core assembly 100N includes a first coupling member 3. The first coupling member 3 may be partially accommodated by the housing 1. The first coupling member 3 may have a first end 31 and a second end 32. The first end 31 of the first coupling member 3 is configured to be mechanically and electrically connected to a first connection portion of the base 200, such as the following Fig.12The first connection portion 230 shown in FIG. The second end 32 of the first coupling member 3 is mechanically and electrically connected to the input side 21 of the circuit device 2n. The second coupling member 4 can be partially accommodated by the housing 1. The second coupling member 4 can have a first end 41 and a second end 42.

When the circuit devices 2b, 2c have first and second coupling members similar to the first and second coupling members 3 and 4 connected to the circuit device 2a, the circuit devices 2b, 2c are connected to the first connection portion 230 and the corresponding second connection portions 240B, 240C on the base 200 through their corresponding first and second coupling members.

[0067] In such a configuration, the corresponding first coupling members 3 of the core assemblies 100A, 100B, 100C, 100N may all be connected to the first connection portion 230 .

In some embodiments, one of the plurality of grooves 231A, 231B, 231C, and 231N corresponds to one of the circuit devices 2a, 2b, 2c, and 2n, respectively. That is, one of the grooves 231A, 231B, 231C, and 231N corresponds to the first coupling member 3 of the core assembly 100A, 100B, 100C, and 100N, respectively.

[0071] refer to Fig.13 , the second connection portion 240A includes a groove 241A and a hoop 244A and a set screw 245A threadedly connected to the hoop 244A. The hoop 244A and the set screw 245A can be used to connect external wires. The groove 241A includes a first side 242A and a second side 243A. The groove 241A can mechanically and electrically connect the body 40 of the second coupling member 4 on the first side 242A, and can mechanically and electrically connect the elastically deformable second part 410 of the second coupling member 4 on the second side 243A.

[0072] In some embodiments, the second connection portion 240B, the second connection portion 240C, and the second connection portion 240N may have the same configuration as the second connection portion 240A. One of the second connection portions 240A, 240B, 240C, and 240N may correspond to one of the core components 100A, 100B, 100C, and 100N. Specifically, each of the second connection portions 240A, 240B, 240C, and 240N corresponds to the second coupling member 4 of one core component 100A, 100B, 100C, and 100N, thereby allowing independent surge protection for each phase circuit to be achieved.

[0073] Fig.14 A schematic diagram showing the connection between the first type of core assembly of the present disclosure and the first connecting portion and the second connecting portion is shown. Fig.14 , the circuit device 2a of the core assembly 100A has been connected to the first connection portion 230 and the second connection portion 240A. The elastically deformable first portion 310 of the first coupling member 3 is biased against the side 233A of the first connection portion 230. The elastically deformable second portion 410 of the second coupling member 4 is biased against the side 243A of the second connection portion 240A.

[0074] When the voltage conditions on both sides of the circuit device 2a allow the circuit device 2a to be turned on, the current flows along the arrow direction from the first connection portion 230 through the circuit device 2a to the second connection portion 240A. In some embodiments, the input side 21 and the output side 22 of the circuit device 2a can be respectively arranged on the side of the circuit device 2a adjacent to the first connection portion 230 and the side adjacent to the second connection portion 240. Fig.14 As shown, the input side 21 and the output side 22 can face each other. This has the advantage that a conductive path as shown in the figure can be generated. Compared with a traditional conductive path, such a conductive path is shorter, making surge protection more timely and effective.

[0075] When the connection between the circuit device 2a and the first coupling member 3 has been destroyed and the circuit device 2a needs to be replaced, the connection between the first coupling member 3 and the first connection portion 230 and the connection between the second coupling member 4 and the second connection portion 240A can be disconnected by simply pulling out the core assembly 100A relative to the base 200. In addition, the new core assembly 100A can be conveniently mechanically and electrically connected to the first connection portion 230 and the second connection portion 240A using the first coupling member 3 and the second coupling member 4. This facilitates the rapid replacement of the core assembly 100A. The core assemblies 100B, 100C, and 100N also have similar benefits when using first coupling members and second coupling members similar to the first coupling member 3 and the second coupling member 4, which will not be described in detail here.

Rather, the specific features and acts described above are disclosed as example forms of implementing the claims.
