Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 5, an oscillating capacitor head includes: silica gel power cord (1), on the metal negative pole (2), under the metal negative pole (3), on the ceramic chip (7), under the ceramic chip (8), positive plate (13), negative pole piece (14), negative pole transmission piece (16), high strength bolt (15), waterproof circle (11) and first insulating material (6), second insulating material (10), wherein, the connection form of first metal casing (5) and second metal casing (9) is many big tooth pitch screw threads, its rotation angle is less than 90 degrees when two are connected.

Preferably, the waterproof ring (11) is a sealing ring, and has double waterproof effects, so that the waterproof grade of the waterproof ring is more than IP 8.

Referring to the exploded view of fig. 6, in the embodiment of the present invention, the

first metal shells

5, 9, 16 are formed by machining or die-casting hardware, and are made of aluminum or aluminum alloy, wherein the

first metal shells

5, 9 need to be surface-treated, and are insulated by oxidation or spraying, the second metal shell 9 has large-pitch threads and a sealing groove, the large-pitch threads are matched with the first metal shell 5 pitch, the sealing groove is decorated with a waterproof ring during assembly, and the large-pitch threads are coated with waterproof glue, so that the first metal shell 5 and the second metal shell 9 are assembled to achieve a double-layer sealing effect; the second metal shell 9 has an insulating outer surface but a conductive side surface as shown in FIG. 2

components

7 and 8 are ceramic sheets or powder metallurgy sheets, and are fixed on the second metal casing 9 through the positive and

negative electrode sheets

13 and 14 and the negative electrode transfer sheet (16) through the high strength bolt (15). The second metal shell 9 has a filler 8A therein, a first insulating material (6) and a second insulating material (10) between the positive and negative electrodes
