Embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is discussed in detail.
Refering to Fig. 1 to Fig. 5, the present invention provides a kind of waterproof anti-explosion AC capacitor, including metal shell 1, capacitor core 2
With end cap 3, the capacitor core 2 is set in metal shell 1, and the upper and lower end of capacitor core 2 is respectively equipped with positioning sleeve 4 with
Positioning sleeve 5, end cap 3 is sealedly connected on the opening portion of metal shell 1, and capacitor core 2 is provided with lead, and lead is passed through after end cap 3
It is connected to the inserted sheet 6 on the end cap 3, the side wall rolled with waveform ring 101 of metal shell 1, it is upper fixed that the waveform ring 101 is located at
Between position set 4 and the end cap 3；In order that blast is to automatically power off, stem is provided with capacitor core 2, positioned at the stem
Rolled with breach 201 on the interior lead stretched, it is preferred that first flatten the lead center crush stretched the formation in stem
Portion 202, and open up jagged 201 in the flattening portion；In order to reach better seal effect, at the opening of metal shell 1
Inside bending forms sealing (bound edge), and end cap 3 is located between sealing and waveform ring 101；In order to reach more preferable waterproof effect,
It is arranged with the top of metal shell 1 on cover 7, cover 7 and is sealedly connected with sleeve pipe 8, preferential, lead between sleeve pipe 8 and cover 7
Cross rubber stopper realization to be tightly connected, wire 9 is provided with sleeve pipe, the wire 9 is connected with inserted sheet 6, in order to be able to which preferably release is exploded
In the energy of generation, the present embodiment, metal shell 1 is cylindrical and made of aluminum；In the present embodiment, in the side of metal shell 1
The inside bending of wall forms waveform ring 101, and the cross section of the waveform ring 101 is U-shaped, or W-shape, and can be one
It is individual or multiple.
Waterproof anti-explosion AC capacitor of the present invention is cylindrical aluminium shell, is the mistake that this lead-out wire is broken in outer shell wall elongation
Pressure isolation protection mechanism.
In capacitor fabrication process, after capacitor body loads metal shell, with special equipment in capacitor case
Position higher than fuse around shell cylinder rolls out one of depression arc-shaped slot.Then arc-shaped slot is pressed into a ripple folding
Ring, close the lid edge curling seal.When welding two leads, the lead through stem will be stretched and firm welding, in the middle of lead
Flattening forms easily broken breach, that is, excess pressure isolation anti-explosion mechanism has been made.
The explosion-proof mechanism of this anti-explosion mechanism is when capacitor breakdown fails, because thin film dielectrics and impregnated material are puncturing
High arc temperature effect is lower to produce a large amount of gases, capacitor case internal pressure is raised rapidly, is enough to make shell when pressure reaches
The ripple ring of wall is re-expanded when coming, and shell wall is that the lead stretched in elongation, stem is pulled off, so that capacitor
With isolated from power, disruptive discharge stops in capacitor, and casing internal pressure stops rising, and shell will not explode, i.e., up to explosion-proof mesh
's.
Waterproof anti-explosion AC capacitor of the present invention, simple in construction, manufacturing cost is low, with good waterproof anti-explosion function,
Using safety and service life is long.
