[0031] Embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0032] The term "comprising" and its variations as used herein signify open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc., may refer to different or the same objects.

[0033] In some conventional surge protectors, independent clips are used to secure two adjacent base modules. These clips are difficult to remove once installed. Factory repairs require damaging these clips, resulting in component damage and increased costs. Removing the clips, however, would cause the base modules to become loose, affecting the stability of the circuit connection.

[0034] This disclosure provides an embodiment of a base module for a surge protector and a surge protector. The base module includes multiple bases. The multiple bases are arranged sequentially along a first direction. Adjacent bases abut against each other. One of the adjacent bases includes a groove. The other of the adjacent bases includes a protrusion. The protrusion is slidably connected to a corresponding groove along a second direction, which can limit the relative separation of the multiple bases in the first direction, wherein the second direction has an angle with the first direction. Using this arrangement, adjacent bases can slide along the second direction, thereby achieving flexible assembly or disassembly. Factory repairs will not damage the bases, and no additional snap-fit ​​connectors are required. Simultaneously, the multiple bases can maintain a stable connection in the first direction, thereby preventing loosening of the multiple bases and affecting the stability of the circuit connection. The following will describe... Figures 1 to 9 The principles of this disclosure will be described in detail below.

[0035] like Figure 1 As shown, surge protectors can be connected in parallel in the electrical system requiring protection. Under high current surges caused by lightning strikes, electrostatic discharge, or other abnormal voltage changes, they quickly conduct, providing a low-impedance path for the abnormal current, allowing it to be discharged to the ground through the protector, thus preventing damage to the main electrical equipment. During use, one surge protection module 200 can be connected at each circuit branch. For example, in a three-phase circuit system, four surge protection modules 200 are electrically connected to the three phase lines and the neutral line of the three-phase circuit, thereby improving the three-phase circuit's resistance to lightning strikes and abnormal voltages. The surge protector may also include a base module 100. Multiple surge protection modules 200 are detachably mounted on the base module 100.

[0036] like Figure 1 As shown, the base module 100 includes multiple bases 10. The multiple bases 10 are arranged sequentially along a first direction X. As an example, a single base 10 can be a rectangular module in general, and the space occupied can be reduced when multiple bases 10 are arranged side by side. Two adjacent bases 10 abut against each other, which can reduce the gap between the bases 10 and can support each other, thereby improving the stability of adjacent bases 10.

[0037] like Figure 1As shown, one of two adjacent bases 10 includes a groove 11. The other of two adjacent bases 10 includes a protrusion 12. The protrusion 12 can be slidably connected to the corresponding groove 11 along a second direction Y, thereby limiting the relative separation of the multiple bases 10 in a first direction X. As an example, a base module 100 for a three-phase circuit may include four bases 10. The right side of each of the three bases 10 on the left side may be provided with a groove 11, and the left side of each of the three bases 10 on the right side may be provided with a protrusion 12. When the four bases 10 are arranged side by side, the protrusion 12 on the first base 10 on the right side is inserted into the groove 11 of the second base 10 on the right side, the protrusion 12 on the second base 10 on the right side is inserted into the groove 11 of the third base 10 on the right side, and the protrusion 12 on the third base 10 on the right side is inserted into the groove 11 of the leftmost base 10.

[0038] During assembly, an operator can slide one of the multiple bases 10 along the second direction Y to attach it to an adjacent base 10. During in-plant rework disassembly, an operator can slide one of the multiple bases 10 along the second direction Y to remove it from an adjacent base 10. The groove 142 allows the corresponding protrusion 12 to slide within it along the second direction Y, while restricting the other five degrees of freedom of the protrusion 12. The second direction Y has an angle with the first direction X, so the protrusion 12 and the groove 142 can restrict the multiple bases 10 from being relatively separated in the first direction X.

[0039] In some embodiments, the base module 100 may also include two bases 10. One of the two bases 10 includes a groove 11. The other base 10 includes a protrusion 12. The protrusion 12 may be slidably connected to the groove 11 in a second direction Y, thereby limiting the relative separation of the two bases 10 in a first direction X.

[0040] In other embodiments, the base module 100 may also be configured with any number of bases 10 as needed, thereby adapting to different application scenarios. It should be noted that the numbers, values, etc., mentioned above and elsewhere in this disclosure are exemplary and are not intended to limit the scope of this disclosure in any way. Any other suitable numbers or values ​​are possible.

[0041] Using this arrangement, two adjacent bases 10 can slide along the second direction Y, thus enabling flexible assembly or disassembly. In-factory repairs will not damage the bases 10, and no additional snap-fit ​​connectors are required. Simultaneously, the multiple bases 10 can maintain a stable connection in the first direction X, preventing them from becoming loose in the first direction X and affecting the stability of the circuit connection.

[0042] In some embodiments, such as Figure 1 As shown, the second direction Y is perpendicular to the first direction X. As an example, multiple bases 10 can be arranged sequentially from left to right, and the slide 11 can extend in the front-back direction. When assembling the base module 100, an operator can slide one of the multiple bases 10 in the front-back direction to attach it to an adjacent base 10. During in-factory rework disassembly, an operator can slide one of the multiple bases 10 in the front-back direction to remove it from an adjacent base 10.

[0043] In other embodiments, multiple bases 10 may be arranged sequentially from left to right, and the slide groove 11 may extend vertically. When assembling the base module 100, an operator can slide one of the multiple bases 10 vertically to attach it to an adjacent base 10. During in-factory rework and disassembly, an operator can slide one of the multiple bases 10 vertically to remove it from an adjacent base 10.

[0044] In other embodiments, the groove 11 may extend in other directions. Any other suitable included angle is possible.

[0045] In some embodiments, such as Figure 2 and Figure 3 As shown, in order to improve the stability of the connection between two adjacent bases 10, multiple sliding grooves 11 and multiple protrusions 12 can be provided on the two adjacent bases 10. In this way, when assembling the base module 100, the multiple sliding grooves 11 are slidably connected to the corresponding protrusions 12 among the multiple protrusions 12.

[0046] As an example, such as Figure 2 and Figure 3 As shown, protrusion 12 includes a first sub-protrusion 1201 and a second sub-protrusion 1202. Slide 11 includes a first sub-slide 1101 and a second sub-slide 1102. The first sub-protrusion 1201 and the second sub-protrusion 1202 are respectively arranged on a pair of opposite sides of the corresponding base 10. The first sub-slide 1101 and the second sub-slide 1102 are respectively arranged on a pair of opposite sides of the corresponding base 10. For example, the first sub-protrusion 1201 can be located on the front side of the first right base 10, and the second sub-protrusion 1202 can be located on the rear side of the first right base 10. The first sub-slide 1101 can be located on the front side of the second right base 10, and the second sub-slide 1102 can be located on the rear side of the second right base 10. With this arrangement, when assembling the base module 100, the first sub-protrusion 1201 is slidably connected to the first sub-slide groove 1101, and the second sub-protrusion 1202 is slidably connected to the second sub-slide groove 1102.

[0047] In other embodiments, the first sub-protrusion 1201 may be disposed on the front side of the first right base 10, and the second sub-slide 1102 may be disposed on the rear side of the first right base 10. The first sub-slide 1101 may be disposed on the front side of the second right base 10, and the second sub-protrusion 1202 may be disposed on the rear side of the second right base 10. With this arrangement, when assembling the base module 100, the first sub-protrusion 1201 is slidably connected to the first sub-slide 1101, and the second sub-protrusion 1202 is slidably connected to the second sub-slide 1102.

[0048] As an example, the cross-sectional shapes of the first sub-protrusion 1201 and the second sub-protrusion 1202 can be the same, and the cross-sectional shapes of the first sub-groove 1101 and the second sub-groove 1102 can be the same. In this way, mold costs can be reduced and the manufacturing efficiency of the protrusion 12 can be improved.

[0049] As another example, the cross-sectional shapes of the first sub-protrusion 1201 and the second sub-protrusion 1202 can be different, and the cross-sectional shapes of the first sub-groove 1101 and the second sub-groove 1102 can be different. In this way, when the first sub-protrusion 1201 is inserted into the first sub-groove 1101 and the second sub-protrusion 1202 is inserted into the second sub-groove 1102, loosening between the two adjacent bases 10 can be better restricted.

[0050] In some embodiments, such as Figure 4 and Figure 5 As shown, the groove 11 includes a groove bottom 111 and an opening 112 arranged along a first direction X. The cross-sectional width of the groove bottom 111 of the groove 11 is greater than the cross-sectional width of its opening 112. The protrusion 12 includes a first end 121 and a second end 122 disposed opposite to each other. The second end 122 of the protrusion 12 is closer to the groove bottom 111 of the corresponding groove 11 than the first end 121 of the protrusion 12. The cross-sectional width of the second end 122 is greater than the cross-sectional width of the first end 121. With this arrangement, when the protrusion 12 is inserted into the corresponding groove 11, the second end 122 of the protrusion 12 is located at the groove bottom 111 of the groove 11, and the first end 121 of the protrusion 12 is located at the opening 112 of the groove 11. Since the cross-sectional width of the groove bottom 111 of the groove 11 is greater than the cross-sectional width of its opening 112, the second end 122 of the protrusion 12 cannot be pulled out from the opening 112 of the groove 11, thereby limiting the relative separation of adjacent bases 10 along the first direction X.

[0051] In some embodiments, such as Figure 4As shown, the cross-sectional width of the groove 11 gradually decreases along the extension direction from its bottom 111 to its opening 112. The cross-sectional width of the protrusion 12 gradually increases along the extension direction from the first end 121 to the second end 122. With this arrangement, the cross-sectional width of the groove 11 gradually decreases, forming a funnel-shaped structure. The cross-sectional width of the protrusion 12 gradually changes, forming an inverted cone-shaped structure. When the protrusion 12 is inserted into the groove 11, the groove 11 can prevent the protrusion 12 from being pulled out from its opening 112.

[0052] In other embodiments, such as Figure 5 As shown, the slide 11 includes two rectangular segments arranged sequentially along a first direction X, and the cross-sectional width of the rectangular segment at the bottom 111 is greater than the cross-sectional width of the rectangular segment at the opening 112. The first end 121 and the second end 122 of the protrusion 12 are rectangular blocks with different cross-sectional widths, and the width of the rectangular block at the second end 122 is greater than the width of the rectangular block at the first end 121. With this arrangement, the rectangular block at the second end 122 can be inserted into the rectangular segment at the bottom 111, and the rectangular block at the first end 121 can be inserted into the rectangular segment at the opening 112. Since the cross-sectional width of the rectangular segment at the bottom 111 is greater than the cross-sectional width of the rectangular segment at the opening 112, when the protrusion 12 is inserted into the slide 11, the slide 11 can prevent the protrusion 12 from being pulled out from its opening 112.

[0053] In some embodiments, such as Figures 6 to 8 As shown, to further improve the stability when multiple bases 10 are connected, a limiting connection structure can be provided at the bottom of the base 10. As an example, one of two adjacent bases 10 includes a limiting groove 13 at its bottom, and the other of the two adjacent bases 10 includes a connecting portion 14 at its bottom. When the connecting portion 14 is inserted into the limiting groove 13, the two cooperate to limit the movement of the two adjacent bases 10.

[0054] like Figure 6 As shown, when the connecting part 14 is inserted into the limiting groove 13 and one side of the connecting part 14 abuts against the front side wall of the limiting groove 13, the protrusion 12 is inserted into the corresponding sliding groove 11. Since the connecting part 14 is blocked by the front side wall of the limiting groove 13, the base 10 can be prevented from sliding further along the second direction Y.

[0055] In some embodiments, such as Figures 6 to 8 As shown, the adjacent base 10 also includes a backstop structure provided at the connecting portion 14 and the limiting groove 13. In this way, when one side of the connecting portion 14 abuts against the front side wall of the limiting groove 13, the backstop structure can limit the connecting portion 14 at the front side wall of the limiting groove 13, thereby fixing the protrusion 12 in the corresponding sliding groove 11.

[0056] As an example, such as Figures 6 to 8 As shown, one of the two adjacent bases 10 further includes a stop portion 131 disposed on the inner sidewall of the limiting groove 13. The stop portion 131 may be a protruding structure with an inclined surface or an arc surface. The other base 10 of the two adjacent bases 10 further includes an elastic portion 141 disposed at one end of the connecting portion 14. The elastic portion 141 deforms when subjected to force and returns to its original shape after the external force is removed. After the connecting portion 14 is inserted into the limiting groove 13, the connecting portion 14 is slidably connected to the limiting groove 13 along the second direction Y and is adapted to switch between an inserted position and a fixed position.

[0057] like Figure 7 As shown, the connecting portion 14 of the second base 10 on the right is in the insertion position. Figure 8 As shown, the connecting portion 14 of the second base 10 on the left is in the insertion position. When the connecting portion 14 is in the insertion position, the protrusion 12 of the base 10 is not inserted into the corresponding groove 11, and the end elastic portion 141 of the connecting portion 14 does not pass over the stop portion 131.

[0058] like Figure 6 As shown, the connecting portion 14 of the second base 10 on the right is in a fixed position. When assembling the base module 100, the operator can continue to slide the base 10 along the second direction Y. The elastic portion 141 deforms and bends upon contact with the stop portion 131, allowing the connecting portion 14 to smoothly reach the fixed position. After passing the stop portion 131, the elastic portion 141 returns to its initial shape under its own elasticity, thus being limited by the stop portion 131. The connecting portion 14 is connected to the elastic portion 141, therefore the connecting portion 14 is limited to the fixed position. Without external force interference, the connecting portion 14 is stably in the fixed position. When disassembling the base 10, the operator can apply force to the elastic portion 141. After deformation, the elastic portion 141 can pass over the stop portion 131, causing the connecting portion 14 to retract to the insertion position. At this time, the protrusion 12 slides out from the corresponding groove 11, thereby removing one base 10 from the adjacent base 10.

[0059] In some embodiments, such as Figure 7As shown, one of the two adjacent bases 10 also includes a protrusion 132 disposed at the edge of the limiting groove 13. The connecting portion 14 of the other two adjacent bases 10 includes a groove 142 extending along the second direction Y. With this arrangement, when the connecting portion 14 is in the inserted position and the protrusion 132 is not inserted into the groove 142, one base 10 can be detached from the adjacent base 10. When the connecting portion 14 is in the fixed position, the protrusion 132 can be inserted into the groove 142, thereby restricting the relative separation of the two adjacent bases 10 in the first direction X. After the adjacent bases 10 are assembled, the protrusion 132 is inserted into the groove 142, thereby increasing the stability of the adjacent bases 10 in the first direction X.

[0060] This disclosure also provides a surge protector. For example... Figure 9 As shown, the surge protector includes a base module 100 of any of the above types and multiple surge protection modules 200. The multiple surge protection modules 200 are detachably connected to corresponding bases 10 in the multiple bases 10.

[0061] In the surge protector base module 100, two adjacent bases 10 can slide along the second direction Y, enabling flexible assembly or disassembly. Factory repairs will not damage the bases 10, and no additional snap-fit ​​connectors are required. Simultaneously, the multiple bases 10 can maintain a stable connection in the first direction X, thus preventing loosening of the bases 10 and ensuring the stability of the circuit connection.

[0062] In some embodiments, such as Figure 9 As shown, at least some of the surge protection modules 200 may be metal oxide varistor modules. In this way, the metal oxide varistor can operate based on the characteristics of its internal materials, such as zinc oxide. Under normal voltage, the metal oxide varistor module has high resistance and is almost non-conductive. When an overvoltage occurs, its resistance drops rapidly, directing the overvoltage energy to ground, thereby protecting connected equipment from damage. After the overvoltage event, the metal oxide varistor module can return to its high resistance state.

[0063] In other embodiments, such as Figure 9As shown, at least some of the surge protection modules 200 can be gas discharge tube modules. In this manner, the gas discharge tube module maintains an inert gas between two or more electrodes. Under normal operating voltage, the gas discharge tube module exhibits a high-resistivity state and is almost non-conductive. Upon the occurrence of an overvoltage, the gas between the electrodes is ionized, forming a plasma channel that rapidly directs current to ground, bypassing the protected equipment. When the overvoltage disappears, the gas recombines, and the gas discharge tube module returns to its high-resistivity state, ensuring circuit safety.

[0064] As an example, such as Figure 9 As shown, in a three-phase circuit system, a surge protector may include three metal oxide varistor modules and one gas discharge tube module. The three metal oxide varistor modules are electrically connected to the three phase lines of the three-phase circuit, and the gas discharge tube module may be electrically connected to the neutral line of the three-phase circuit.

[0065] In some embodiments, such as Figure 9 As shown, the surge protector also includes a busbar 300. The busbar 300 is electrically connected to multiple bases 10. With this arrangement, in the event of a surge, each module can guide the instantaneous high-energy current to ground through the busbar 300, thereby improving the protection of electrical equipment. Simultaneously, the busbar 300 can also secure the multiple bases 10, thus preventing the bases 10 from becoming loose.

[0066] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
