[0057] The lightning arrester base is a basic component used when installing the lightning arrester plug. It is usually used to fix the lightning arrester plug and ensure the stable and effective connection of the lightning arrester plug in the electrical system.

[0058] The existing lightning arrester base includes a housing, current bars, and a switch assembly. The housing has a card slot adapted to the lightning arrester plug; the number of current bars is set to two, and each current bar includes a current bar body and a pin structure. The current bar body is installed inside the housing and is electrically connected to the pins of the lightning arrester plug, and the pin structure extends outside the housing for soldering to a circuit board.

[0059] In order to achieve enhanced insulation / double insulation for the existing lightning arrester base, the switch assembly is arranged on the other side of the two current bars, and a certain distance needs to be ensured between the switch assembly and each current bar, which results in a relatively large size of the entire lightning arrester base.

[0060] Therefore, it is indeed necessary to improve the existing technology to address the deficiencies of the existing technology.

[0061] Based on this, a lightning arrester base and a lightning arrester provided in the present application include a housing, current bars, a switch assembly, and a switch trigger assembly. The current bars are arranged on opposite sides of the housing, and the switch assembly is located between the current bars.

[0062] During the specific use process, when the lightning arrester plug is inserted into the card slot formed at the top of the housing, the switch trigger assembly is pushed to slide relative to the housing until the switch assembly is exposed. At this time, the switch assembly switches from the normally closed state under pressure to the normally open state; after the lightning arrester plug is disconnected from the above-mentioned card slot, the switch trigger assembly slides relative to the housing and covers the switch assembly, and the switch assembly is pressed by the switch trigger assembly and switches from the normally open state to the normally closed state again.

[0063] Compared with the arrangement of the switch assembly and each current bar in the existing lightning arrester base, in the present application, each current bar is arranged on both sides of the housing, which can meet the requirements of enhanced insulation / double insulation for the main and auxiliary circuits, and has the characteristics of high integration and miniaturization in the industrial field, saving costs.

[0064] The technical solution of the present application will be described in detail below with specific embodiments in conjunction with the accompanying drawings. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0065] Refer to Figure 1 、 Figure 4 and Figure 5As shown in the figure, an embodiment of the present application provides a lightning arrester base, which includes a housing 100, a current bar 200, a switch assembly 300, and a switch trigger assembly 400; the top of the housing 100 has a card slot 111 that is recessed towards the inside of the housing 100, and the card slot 111 is used to connect the lightning arrester plug; the current bars 200 are arranged on opposite sides of the housing 100; both the switch assembly 300 and the switch trigger assembly 400 are installed inside the housing 100, the switch assembly 300 is located between the current bars 200, and the switch trigger assembly 400 can slide relative to the housing 100; the switch trigger assembly 400 is configured to expose the switch assembly 300 when the lightning arrester plug is connected to the card slot 111; when the lightning arrester plug is disconnected from the card slot 111, it covers the switch assembly 300 to press the switch assembly 300.

[0066] It can be understood that in the present application, there are no restrictions on the size and specific shape of the card slot 111, as long as it can be adapted to the lightning arrester plug.

[0067] During the specific use process, when the lightning arrester plug is inserted into the card slot 111 formed at the top of the housing 100, the switch trigger assembly 400 is pushed to slide relative to the housing 100 until the switch assembly 300 is exposed. At this time, the switch assembly 300 switches from the normally closed state under pressure to the normally open state; when the lightning arrester plug is disconnected from the above-mentioned card slot 111, the switch trigger assembly 400 slides relative to the housing 100 and covers the switch assembly 300, and after the switch assembly 300 is pressed by the switch trigger assembly 400, it switches from the normally open state to the normally closed state again.

[0068] Compared with the existing layout of the switch assembly 300 and each current bar 200 in the lightning arrester base, in the present application, each current bar 200 is arranged on both sides of the housing 100. On the premise of meeting the requirements of enhanced insulation / double insulation, it has the characteristics of high integration and miniaturization in the industrial field, saving costs.

[0069] In some embodiments, the housing 100 includes an upper housing 110 and a bottom case 120, and the upper housing 110 and the bottom case 120 are detachably connected; the top of the upper housing 110 has a card slot 111, and the current bars 200 are arranged on opposite sides of the upper housing 110; both the switch assembly 300 and the switch trigger assembly 400 are installed on the upper housing 110.

[0070] Here, the housing 100 is split into the upper housing 110 and the bottom case 120. The purpose is that when the components inside the housing 100 are damaged, it is convenient for the staff to directly repair or replace the damaged components, rather than replacing the entire lightning arrester base, reducing the maintenance cost.

[0071] Further, in some embodiments, the switch trigger assembly 400 includes an elastic member 410 and a sliding plate 420. The sliding plate 420 is located between the upper housing 110 and the bottom case 120, and the sliding plate 420 slides under the action of the elastic member 410, so that the sliding plate 420 can reciprocate between a first position and a second position. In the first position, the sliding plate 420 covers the switch assembly 300 to press against the switch assembly 300; in the second position, the sliding plate 420 moves to one side of the switch assembly 300 to expose the switch assembly 300 and compress the elastic member 410.

[0072] In a specific implementation, when the lightning arrester plug is inserted into the card slot 111 and pushes the sliding plate 420 to move to one side of the switch assembly 300, the elastic member 410 is compressed and generates an elastic force. After the sliding plate 420 receives the elastic force from the elastic member 410, it has a tendency to move back from the second position to the first position; after the lightning arrester plug is disconnected from the card slot 111, the sliding plate 420 resets to the first position and covers the switch assembly 300 again, simplifying the operation required to trigger the switch assembly 300.

[0073] At the same time, it can be understood that in the present application, the specific structure of the elastic member 410 is not limited, it can be a spring or other types of elastic members, and the staff can select and use it according to the actual situation.

[0074] Still further, in some embodiments, the sliding plate 420 includes a sliding plate body 421 and an arc-shaped guiding portion 422 provided on one side of the sliding plate body 421. The guiding portion 422 slides on a side wall of the upper housing 110 under the action of the elastic member 410; the bottom case 120 has a side surface 121 with an arc-shaped surface, and the arc-shaped surface of the side surface 121 matches at least a part of the outer surface of the guiding portion 422, and at least a part of the guiding portion 422 abuts against the side surface 121.

[0075] It can be understood that in the present application, the specific shape of the sliding plate 420 is not limited, as long as it can slide relative to the housing 100 to switch the state of the switch assembly 300. Specifically, in the above embodiment, since the top of the upper housing 110 is provided with a card slot 111 adapted to the lightning arrester plug, the upper housing 110 is generally U-shaped, and an arc-shaped guiding portion 422 is provided on one side of the sliding plate body 421. The purpose is to make the shape of the sliding plate 420 more fitting with the shape of the upper housing 110, thereby improving the space utilization rate inside the housing 100.

[0076] Meanwhile, due to the special shape of the sliding plate 420, it is prone to bending during the sliding process, resulting in low efficiency of triggering the switch assembly 300 or even failure to trigger. An arc-shaped side surface 121 is provided on the bottom shell 120, and at least a part of the guiding portion 422 abuts against the side surface 121, so that the bottom shell 120 can support the sliding plate 420 during the sliding process of the sliding plate 420.

[0077] In some embodiments, a first connecting member 112 and a baffle 113 are provided inside the upper shell 110; a through hole 423 is formed at one end of the sliding plate 420, and the first connecting member 112 is inserted into the through hole 423 to fix the sliding plate 420 inside the upper shell 110; the other end of the sliding plate 420 can abut against the baffle 113, and the baffle 113 is used to block the continuous sliding of the sliding plate 420, so that the sliding plate 420 remains covering the switch assembly 300.

[0078] In the above embodiments, the first connecting member 112 can prevent the sliding plate 420 from falling off during the sliding process, and the baffle 113 can limit the sliding state of the sliding plate 420 according to the sliding position of the sliding plate 420 to ensure that the sliding plate 420 can remain covering the switch assembly 300.

[0079] Further, referring to Figure 1 and Figure 3 , in some embodiments, the through hole 423 is set as an elongated hole extending along the moving direction of the sliding plate 420, and the first connecting member 112 can be inserted into different positions in the elongated hole to adapt to fixing the sliding plate 420 at different positions in the upper shell 110.

[0080] In the above embodiments, setting the through hole 423 as an elongated hole extending along the moving direction of the sliding plate 420 makes the connection between the sliding plate 420 and the upper shell 110 more flexible. Even for the sliding plate 420 that reciprocates between the first position and the second position, the first connecting member 300 can still fix the sliding plate 420 at different positions.

[0081] Referring to Figure 1 and Figure 2 , in some embodiments, a second connecting member 114 is provided on the baffle 113 to fix the switch assembly 300 on the baffle 113.

[0082] Here, taking the second connecting member 114 as a bridge, the switch assembly 300 is fixed on the baffle 113, which improves the connection strength between the switch assembly 300 and the upper shell 110, thereby avoiding the situation that the switch assembly 300 is displaced due to the friction force generated between the sliding plate 420 and the switch assembly 300 during the sliding process of the sliding plate 420, resulting in low efficiency of triggering the switch assembly 300 or even failure to trigger.

[0083] In some embodiments, insertion holes 115 are formed in the side wall of the upper housing 110; insertion blocks 122 are arranged on the side wall of the bottom housing 120, and the insertion blocks 122 are inserted into the insertion holes 115 to fix the relative positions between the upper housing 110 and the bottom housing 120.

[0084] It can be understood that in the present application, there is no limitation on the specific connection form between the upper housing 110 and the bottom housing 120, and only the detachable property between the upper housing 110 and the bottom housing 120 needs to be ensured. Specifically, in the above embodiment, insertion holes 115 are formed in the side wall of the upper housing 110, and insertion blocks 122 are arranged on the side wall of the bottom housing 120. Taking the cooperation relationship between the insertion holes 115 and the insertion blocks 122 as a bridge, the detachable connection between the upper housing 110 and the bottom housing 120 is realized, and the structure is simple, which is convenient for the staff to repair and maintain the internal components of the housing 100.

[0085] In some embodiments, receiving grooves 116 are formed on opposite sides of the upper housing 110 to receive the current bars 200.

[0086] Receiving grooves 116 are formed on opposite sides of the upper housing 110 to provide a receiving space for the current bars 200, preventing them from being exposed to the external environment and being affected by the external environment, which may lead to a decline in the overall performance of the lightning arrester base.

[0087] The present application also provides a lightning arrester, including the lightning arrester base as described in any of the foregoing embodiments.

[0088] Among them, the lightning arrester base has been described in detail in the above embodiment and will not be elaborated herein one by one.

[0089] It should be understood that the various forms of processes shown above can be used, with steps reordered, added, or deleted. For example, the steps recited in the disclosure of the present application can be executed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions disclosed in the present application can be achieved, and no limitation is imposed herein.

[0090] The above specific embodiments do not constitute a limitation on the protection scope of the present application. Those skilled in the art should understand that various modifications, combinations, sub - combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the principles of the present application shall be included within the protection scope of the present application.
