[0006] In view of this, the present application provides a lightning protection base and a lightning protection system that can solve the problem that the lightning protection base in the prior art has excessively large dimensions.

[0007] To solve this problem, the following technical solution is used in the lightning protection base according to the present application.

[0008] The present application provides a lightning protection base comprising a housing, busbars, a switch assembly and a switch release assembly, wherein a locking recess is provided on one upper side of the housing, which is recessed towards the inside of the housing and serves for connection with a surge protection plug, the busbars are arranged on two opposite sides of the housing, wherein both the switch assembly and the switch release assembly are mounted inside the housing, wherein the switch assembly is located between the individual busbars and the switch release assembly is slidable relative to the housing, wherein the switch release assembly is configured to expose the switch assembly when the surge protector plug is inserted into the detent; and that the switch release assembly covers the switch assembly and is pressed against the switch assembly when the surge protector plug is disconnected from the detent.

[0009] In one possible implementation, the housing comprises an upper housing and a lower housing, wherein the upper housing and the lower housing are detachably connected to each other. wherein the locking recess is located on a top side of the upper housing, wherein the busbars are arranged on two opposite sides of the upper housing, and wherein both the switch assembly and the switch release assembly are mounted on the upper housing.

[0010] In one possible implementation, the switch release arrangement comprises an elastic element and a sliding plate, wherein the sliding plate is located between the upper housing and the lower housing and slides under the action of the elastic element, so that the sliding plate can be moved back and forth between a first position and a second position, wherein in the first position the sliding plate covers the switch arrangement and is pressed against the switch arrangement, and wherein in the second position the sliding plate moves to one side of the switch arrangement to expose the switch arrangement and compress the elastic element.

[0011] In one possible implementation, the sliding plate comprises a sliding plate body and an arc-shaped guide section located on one side of the sliding plate body, wherein the guide section slides along a side wall of the upper housing under the action of the elastic element. wherein a side surface of the lower housing is an arcuate surface, wherein the arcuate surface of the side surface coincides with at least a part of an arcuate surface of an outer surface of the guide section, and wherein the guide section at least partially abuts the side surface, wherein a side surface of the lower housing represents an arcuate surface, wherein the arcuate surface of the side surface coincides with at least a part of an arcuate surface of an outer surface of the guide section, and wherein the guide section at least partially abuts the side surface.

[0012] One possible implementation envisages that the upper housing contains the first connecting elements and a stop plate. wherein one end of the sliding plate is provided with through holes, wherein the first connecting elements are inserted into the through holes to fasten the sliding plate in the upper housing, wherein the other end of the sliding plate can rest against the stop plate, and wherein the stop plate serves to prevent further sliding of the sliding plate, so that the switch assembly remains covered by the sliding plate.

[0013] In one possible implementation, the through-hole is designed as an elongated hole extending along a direction of movement of the sliding plate, with the first connecting element being able to be inserted at different positions within the elongated hole in order to adaptively attach the sliding plate to the upper housing in different positions.

[0014] One possible implementation provides for second connecting elements to be arranged on the stop plate in order to attach the switch assembly to the stop plate.

[0015] One possible implementation envisages the inclusion of slots on the side walls of the upper housing. wherein plug-in blocks are provided on the side walls of the lower housing, the plug-in blocks being inserted into the plug holes to determine the relative position between the upper housing and the lower housing.

[0016] In one possible implementation, it is envisaged that the two opposite sides of the upper housing are each provided with a receiving groove for receiving the busbars.

[0018] The lightning protection base and lightning protection system according to the present application comprise a housing, busbars, a switch assembly, and a switch release assembly. The busbars are arranged on two opposite sides of the housing, with the switch assembly located between the individual busbars.

[0019] In actual operation, the surge protector plug is inserted into the locking recess on the top of the housing and simultaneously pushes the switch release assembly into a sliding motion relative to the housing until the switch assembly is exposed. The switch assembly is then switched from a normally closed state, in which it was under pressure, to a normally open state. Once the surge protector plug is released from the locking recess, the switch release assembly slides relative to the housing and covers the switch assembly. The pressure exerted by the switch release assembly then switches the switch assembly back from the normally open state to the normally closed state.

[0020] In contrast to the arrangement of the switchgear and individual busbars in existing lightning protection bases, the individual busbars in the present application are arranged on both sides of the housing. This allows the requirements for improved insulation or double insulation to be met. Furthermore, it enables the properties of high integration and miniaturization for industrial applications, leading to cost reductions. Description of the characters

[0030] A lightning protection base is a fundamental component for mounting a lightning protection plug. Its primary function is to secure the lightning protection plug and ensure a stable and effective connection within an electrical system.

[0031] A conventional surge protection base comprises a housing, busbars, and a switch assembly, with the housing featuring a snap-in recess compatible with the surge protection connector. It includes two busbars, each comprising a busbar body and a pin structure. The busbar body is mounted within the housing and electrically connected to pins of the surge protection connector. The pin structure extends beyond the housing for soldering to a printed circuit board.

[0032] In a conventional lightning protection base of this type, a switch assembly is located on the side opposite the two busbars to achieve improved or double insulation. It must be ensured that the switch assembly is positioned at a specific distance from each busbar, which, however, results in a larger overall size for the lightning protection base.

[0033] Therefore, the state of the art should be improved in order to eliminate its disadvantages.

[0034] Based on this, the present application provides a lightning protection base and a lightning protection system comprising a housing, busbars, a switch assembly, and a switch release assembly. The busbars are arranged on two opposite sides of the housing, with the switch assembly located between the individual busbars.

[0035] In actual operation, the surge protector plug is inserted into the locking recess on the top of the housing and simultaneously pushes the switch release assembly into a sliding motion relative to the housing until the switch assembly is exposed. The switch assembly is then switched from a normally closed state, in which it was under pressure, to a normally open state. Once the surge protector plug is released from the locking recess, the switch release assembly slides relative to the housing and covers the switch assembly. The pressure exerted by the switch release assembly then switches the switch assembly back from the normally open state to the normally closed state.

[0036] In contrast to the arrangement of the switchgear and individual busbars in existing lightning protection bases, the individual busbars in the present application are arranged on both sides of the housing. This allows the requirements for improved insulation or double insulation for main and auxiliary circuits to be met. Furthermore, it enables high integration and miniaturization for industrial applications, resulting in cost reduction.

[0037] The technical solutions of the present application are described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined, and some embodiments may not discuss the same or similar concepts or processes in detail.

[0038] With reference to the Fig. 1, Fig. 4 and Fig. Figure 5 provides an embodiment of the present application comprising a lightning protection base comprising a housing 100, busbars 200, a switch assembly 300, and a switch release assembly 400. A locking recess 111 is provided on the upper side of the housing 100, which is recessed towards the interior of the housing 100. The locking recess 111 serves for connection to a lightning protection plug. The busbars 200 are arranged on two opposite sides of the housing 100. Both the switch assembly 300 and the switch release assembly 400 are mounted inside the housing 100, with the switch assembly 300 being located between the individual busbars 200 and the switch release assembly 400 being slidable relative to the housing 100.The switch release assembly 400 is configured to expose the switch assembly 300 when the surge protection plug is inserted into the detent recess 111; and to cover the switch assembly 300 and be pressed against the switch assembly 300 when the surge protection plug is disconnected from the detent recess 111.

[0039] It is understood that in the present application there are no restrictions regarding the size or specific shape of the locking recess 111, provided that it can be compatible with the lightning protection plug.

[0040] In actual operation, the surge protection plug is inserted into the locking recess 111 formed on the top of the housing 100 and simultaneously pushes the switch release assembly 400 into a sliding motion relative to the housing 100 until the switch assembly 300 is exposed. The switch assembly 300 is then switched from a normally closed state, in which it was subjected to pressure, to a normally open state. Once the surge protection plug is released from the locking recess 111, the switch release assembly 400 slides relative to the housing 100 and covers the switch assembly 300. The pressure exerted by the switch release assembly 400 then switches the switch assembly 300 back from its normally open state to its normally closed state.

[0041] In contrast to the arrangement of the switch assembly 300 and the individual busbars 200 in existing lightning protection bases, the individual busbars 200 are arranged on both sides of the housing 100 in the present application. This allows the requirements for improved insulation or double insulation to be met. Furthermore, it enables the properties of high integration and miniaturization for industrial applications, leading to cost reductions.

[0042] In some embodiments, the housing 100 comprises an upper housing 110 and a lower housing 120, wherein the upper housing 110 and the lower housing 120 are detachably connected to each other, wherein the locking recess 111 is located on a top surface of the upper housing 110, wherein the busbars 200 are arranged on two opposite sides of the upper housing 110, and wherein both the switch arrangement 300 and the switch release arrangement 400 are mounted on the upper housing 110.

[0043] The separation of the housing 100 into the upper housing 110 and the lower housing 120 aims to ensure that, in the event of damage to components in the housing 100, a direct repair or replacement of the damaged components by personnel is possible without having to replace the entire lightning protection base, which reduces maintenance and repair costs.

[0044] Furthermore, in some embodiments, the switch release arrangement 400 comprises an elastic element 410 and a sliding plate 420, wherein the sliding plate 420 is located between the upper housing 110 and the lower housing 120 and the sliding plate 420 slides under the action of the elastic element 410, so that the sliding plate 420 can be moved back and forth between a first position and a second position, wherein in the first position the sliding plate 420 covers the switch arrangement 300 and is pressed against the switch arrangement 300, and wherein in the second position the sliding plate 420 moves to one side of the switch arrangement 300 in order to expose the switch arrangement 300 and compress the elastic element 410.

[0045] In practical terms, when the surge protection plug is inserted into the locking recess 111 and the sliding plate 420 moves to one side of the switch assembly 300, the elastic element 410 is compressed, generating an elastic force. Consequently, the sliding plate 420, subjected to this elastic force from the elastic element 410, tends to return from the second position to the first position. As soon as the surge protection plug is disconnected from the locking recess 111, the sliding plate 420 returns to the first position and covers the switch assembly 300 again. This simplifies the handling required to trigger the switch assembly 300.

[0046] At the same time, it is understandable that the present application does not impose any restrictions regarding the specific structure of the elastic element 410. It can be a spring or another type of elastic element. Depending on the actual situation, the personnel can select and use the appropriate type.

[0047] Furthermore, in some embodiments, the sliding plate 420 comprises a sliding plate body 421 and an arcuate guide section 422, which is provided on one side of the sliding plate body 421, wherein the guide section 422 slides along a side wall of the upper housing 110 under the action of the elastic element 410, wherein a side surface 121 of the lower housing 120 represents an arcuate surface, wherein the arcuate surface of the side surface 121 coincides with at least a part of an arcuate surface of an outer surface of the guide section 422, and wherein the guide section 422 bears at least partially against the side surface 121.

[0048] It is understood that in the present application there are no restrictions regarding the specific shape of the sliding plate 420, provided that it can slide relative to the housing 100 to switch the state of the switch arrangement 300. In particular, in the above embodiments, the upper housing 110 is generally U-shaped, since the locking recess 111, compatible with the surge protection plug, is provided on the top of the upper housing 110. Furthermore, the provision of the arc-shaped guide section 422 on one side of the sliding plate body 421 aims to allow the shape of the sliding plate 420 to be better adapted to that of the upper housing 110, thus improving the space utilization in the housing 100.

[0049] Furthermore, due to its special shape, the sliding plate 420 bends slightly during its sliding movement, which can lead to inefficient or failed triggering of the switch assembly 300. For this purpose, the side surface 121 of the lower housing 120 forms an arc-shaped surface. The guide section 422 rests at least partially against the side surface 121, so that the lower housing 120 can support the sliding plate 420 during its sliding movement.

[0050] In some embodiments, it is provided that first connecting elements 112 and a stop plate 113 are arranged in the upper housing 110, wherein one end of the sliding plate 420 is provided with through holes 423, wherein the first connecting elements 112 are inserted into the through holes 423 to fasten the sliding plate 420 in the upper housing 110, wherein the other end of the sliding plate 420 can rest against the stop plate 113, and wherein the stop plate 113 serves to prevent further movement of the sliding plate 420, so that the switch arrangement 300 remains covered by the sliding plate 420.

[0051] In the above embodiments, the first connecting element 112 can prevent the sliding plate 420 from falling out during its sliding movement. Furthermore, the stop plate 113 can limit the sliding state of the sliding plate 420 according to its sliding position, to ensure that the switch assembly 300 remains covered by the sliding plate 420.

[0052] Furthermore, as in Fig. 1 and Fig. As shown in Figure 3, in some embodiments the through-hole 423 is designed as an elongated hole extending along a direction of movement of the sliding plate 420, wherein the first connecting element 112 can be inserted at different positions within the elongated hole in order to adaptively attach the sliding plate 420 to the upper housing 110 in different positions.

[0053] In the embodiments above, the through-hole 423 is designed as an elongated hole extending along the direction of movement of the sliding plate 420, resulting in a more flexible connection between the sliding plate 420 and the upper housing 110. This allows the first connecting element 300 to secure the sliding plate 420 in different positions, even if the sliding plate 420 moves back and forth between the first and second positions.

[0054] As in Fig. 1 and Fig. As shown in Figure 2, in some embodiments it is provided that second connecting elements 114 are arranged on the stop plate 113 in order to attach the switch arrangement 300 to the stop plate 113.

[0055] In this case, the second connecting element 114 serves as a bridge to attach the switch assembly 300 to the stop plate 113, thus improving the connection strength between the switch assembly 300 and the upper housing 110. This prevents situations in which a frictional force arising between the sliding plate 420 and the switch assembly 300 during the sliding movement of the sliding plate leads to a displacement of the switch assembly 300, which would result in inefficient or failed activation of the switch assembly 300.

[0056] In some embodiments, it is provided that plug holes 115 are provided on side walls of the upper housing 110, and plug blocks 122 are provided on side walls of the lower housing 120, the plug blocks 122 being inserted into the plug holes 115 to determine the relative position between the upper housing 110 and the lower housing 120.

[0057] It is understood that the present application does not impose any restrictions regarding the specific connection method between the upper housing 110 and the lower housing 120, provided that separability between the upper housing 110 and the lower housing 120 is ensured. Since, in the above embodiments, plug holes 115 are provided on the side walls of the upper housing 110 and plug blocks 122 are provided on the side walls of the lower housing 120, the locating relationship between the plug holes 115 and the plug blocks 122 serves, in particular, as a bridge to enable a detachable connection between the upper housing 110 and the lower housing 120. This results in a simple structure and facilitates easy maintenance and servicing of the components in the housing 110 by personnel.

[0058] In some embodiments, it is provided that the two opposite sides of the upper housing 110 are each provided with a receiving groove 116 for receiving the busbars 200.

[0059] By providing the two opposite sides of the upper housing 110 with the receiving groove 116, a receiving space is provided for the busbars 200. This prevents the busbars from being exposed to the external environment, being affected by the external environment, and thus preventing any impairment of the overall performance of the lightning protection base.

[0060] The present application further provides a lightning protection system comprising a lightning protection base according to one of the above embodiments.

[0061] Since the lightning protection base has already been described in detail in the above examples, no further explanation is given here.

[0062] It is understood that the processes described above can be used in various forms, and steps can be added, deleted, or executed in a different order. For example, individual steps in the disclosure of the present application can be executed in parallel, in the specified order, or in a different order, provided that the desired result of the technical solutions in the disclosure of the present application can be achieved. There is no limitation in this respect.

[0063] The detailed embodiments described above do not in any way restrict the scope of protection of the present application. A person skilled in the art should understand that, depending on the design requirements and other factors, various modifications, combinations, sub-combinations, and substitutions are possible. All modifications, equivalent substitutions, and further developments that fall within the scope of the principle of the present application are intended to be included in the scope of protection of the present application.
