Embodiment
Below in conjunction with accompanying drawing, introduce in detail the utility model embodiment.
Consult Fig. 1 to Fig. 4, the utility model provides a kind of waterproof anti-explosion AC capacitor, comprise metal shell 1, capacitor core 2 and end cap 3, this capacitor core 2 is set in metal shell 1, the upper and lower end of capacitor core 2 is respectively equipped with positioning sleeve 4 and lower positioning sleeve 5, end cap 3 is sealedly connected on the peristome of metal shell 1, capacitor core 2 is provided with lead-in wire, lead-in wire is through being connected to the inserted sheet 6 being positioned on end cap 3 after end cap 3, the sidewall of metal shell 1 rolls waveform ring 101, and this waveform ring 101 is between upper positioning sleeve 4 and described end cap 3; Be can auto-breaking in order to make blast, in capacitor core 2, be provided with stem stem, be positioned at and on the stretching lead-in wire of this stem stem, roll jaggedly, preferred, the stretching lead-in wire center crush that first will be positioned at stem stem forms flattening portion, and offers breach in this flattening portion; In order to reach better sealing effectiveness, form sealing (bound edge) in the inside bending of opening part of metal shell 1, end cap 3 is between sealing and waveform ring 101; In order to reach better waterproof effect, be arranged with cover 7 at the top of metal shell 1, on cover 7, be sealedly connected with sleeve pipe 8, preferential, between sleeve pipe 8 and cover 7, realize and being tightly connected by rubber stopper, in this sleeve pipe 8, be provided with wire 9, this wire 9 is connected with inserted sheet 6, and the energy producing in order to discharge blast, in the present embodiment,, metal shell 1 is cylindrical and made of aluminum; In the present embodiment, form waveform ring 101 in the inside bending of sidewall of metal shell 1, the cross section of this waveform ring 101 is U-shaped, can be also W shape, and can be one or more.
The utility model waterproof anti-explosion AC capacitor is cylindrical aluminium shell, is that outer shell wall extends the excess pressure insulation blocking mechanism that breaks this outlet.
In capacitor fabrication process, when capacitor body packs into after metal shell, roll out one depression arc-shaped slot higher than the position of fuse around shell cylinder at capacitor case with special equipment.Then arc-shaped slot is pressed into a ripple ring, cover lid edge curling seal.In the time of two lead-in wires of welding, want stretching and firm welding through the lead-in wire of stem stem, lead-in wire center crush forms easily broken breach, has made excess pressure isolation anti-explosion mechanism.
The explosion-proof mechanism of this anti-explosion mechanism is in the time that capacitor breakdown lost efficacy, because thin film dielectrics and impregnated material produce a large amount of gas puncturing under high arc temperature effect, capacitor case internal pressure is raise rapidly, when pressure reaches while being enough to make the ripple ring of shell wall again to extend, shell wall extends, lead-in wire stretching in stem stem is pulled off, thereby make capacitor and isolated from power, in capacitor, disruptive discharge stops, casing internal pressure stops rising, shell can not explode, and reaches explosion-proof object.
The utility model waterproof anti-explosion AC capacitor, simple in structure, low cost of manufacture, has good waterproof anti-explosion function, uses safety and long service life.
