Labeled as: the anti-lightning device comprises a base 101, an external terminal 102, a cover plate 103, a second shifting block 104, an electrode hole 105, a first shifting block 106, an inserting piece 107, a plug 108, a rectangular through hole 109, a sliding block 110, a spring 111, a lightning protection module 201, a finger groove 202, a hook 203, a slot 204 and an electrode terminal 205.

Detailed Description

As shown in the figure, a plug-in lightning protection device, includes base 101, is equipped with the mounting groove at base 101 up end, can insert in the mounting groove and be equipped with a plurality of lightning protection module 201, and the number of lightning protection module 201 is decided according to the user demand.

The lower end of the lightning protection module 201 is provided with an electrode terminal 205, the bottom of the mounting groove is provided with an electrode hole 105, and the base 101 is provided with an external terminal 102. After the lightning protection module 201 is inserted into the mounting groove, the electrode terminal 205 is inserted into the electrode hole 105, and then the external terminal 102 is connected with other devices, thereby achieving the lightning protection effect.

A hook 203 is arranged on the side surface of the lightning protection module 201. The base 101 at the groove wall of the mounting groove is provided with a first sliding groove communicated with the mounting groove, and a sliding block 110 is transversely slidably mounted in the first sliding groove. The upper end of the sliding block 110 is fixedly connected with a first shifting block 106, and the first shifting block 106 penetrates through a rectangular through hole 109 formed in the base 101 and extends out of the base 101. When the electrode terminal 205 is inserted into the electrode hole 105, the hook 203 is inserted into the first sliding slot, so that the lightning protection module 201 cannot be pulled out. When the lightning protection module 201 needs to be detached, the first shifting block 106 is shifted to enable the sliding block 110 to abut against the first hook 203, so that the first hook 203 is deformed to leave the first sliding groove, and the lightning protection module 201 can be pulled out at the moment.

In order to make the sliding block 110 automatically return after the sliding block abuts against the hook 203 to deform, a spring 111 is connected between one end of the sliding block 110, which is far away from the mounting groove, and one groove wall of the sliding groove. When the first shifting block 106 is shifted to enable the sliding block 110 to abut against the hook 203, the spring 111 is in a stretching state; after the lightning protection module 201 is detached, the first shifting block 106 is released, and the sliding block 110 is returned to the original position under the elastic force of the spring 111.

In order to prevent the first shifting block 106 from being touched to move the sliding block 110, i.e. in order to prevent the sliding block 110 from being touched to deform the hook 203, a cover plate 103 is hinged to the base 101, and the first shifting block 106 can be covered by the cover plate 103. A locking mechanism is also mounted on the base 101, by which the cover plate 103 can be fixed.

Specifically, the locking mechanism includes a second shifting block 104 slidably mounted in a second sliding slot formed in the base 101, and the second shifting block 104 is fixedly connected with a bolt 108. The cover plate 103 is provided with an insertion hole. After the cover plate 103 is covered, the second shifting block 104 is shifted, and the bolt 108 is inserted into the jack to fix the cover plate 103.

In order to allow the electrode terminals 205 to be accurately inserted into the electrode holes 105, an alignment mechanism is provided on a groove wall of the mounting groove, and the electrode terminals 205 may be aligned with the corresponding electrode holes 105 by the alignment mechanism.

Specifically, the alignment mechanism includes a plurality of pairs of insertion pieces 107 disposed on the wall of the mounting groove. The lightning protection module 201 has a pair of slots 204 on the side thereof. When the lightning protection module 201 is inserted into the mounting slot, the insertion piece 107 may be inserted into the insertion slot 204, thereby aligning the electrode terminal 205 with the corresponding electrode hole 105.

After the lightning protection module 201 is inserted into the mounting groove, because the lightning protection module 201 is completely inserted into the mounting groove, in order to take out the lightning protection module 201 conveniently, a pair of finger grooves 202 are arranged on the upper end face of the lightning protection module 201. When the lightning protection module 201 needs to be taken out, fingers can be scratched into the finger grooves 202, so that the lightning protection module 201 is convenient to take out.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
