Abstract
The utility model discloses an explosion-proof capacitor. The capacitor comprises an aluminum shell and two terminals. An upper portion of an inner cavity of the aluminum shell is provided with a rubber cushion layer and a lower portion is provided with a core. The core is connected to the two terminals through a lead. An aluminums cylinder whose lower portion is provided with an opening sleeves an external portion of the aluminum shell. A foam concrete layer is arranged between the aluminums cylinder and the aluminum shell. An edge of the opening of the lower portion of the aluminums cylinder is bended inwardly so as to form a flanging. An aluminums cover plate is clamped to the flanging. Simultaneously, an upper end surface of the aluminums cylinder is provided with an explosion-proof hole. A lower surface of the aluminums cover plate is provided with a cross reinforcing rib which is protruded downwardly. Two ceramic cushion blocks are fixed to an external portion of an upper end of the aluminums cylinder and the two terminals are fixed to the two ceramic cushion blocks respectively. The capacitor of the utility model has the advantage that an influence caused by fracture is small.
Description
Technical field
The present invention relates to electronic component technology field, especially relate to a kind of noinductive capacitor.
Background technology
Capacitor is one of the most important and common electronic component.Although capacitor has various ways and type,, conventional capacitor includes aluminum hull and binding post, and the inner chamber top of this aluminum hull is provided with rubber spacer, bottom is provided with fuse, and this fuse connects this binding post by wire.Because capacitor frequency of utilization is higher, therefore people's utmost point wishes that it has stable performance, such as, wish that the impact causing when breaking appears in capacitor is less.
Summary of the invention
The object of this invention is to provide a kind of noinductive capacitor, it has the less feature of impact causing while occurring breaking.
The technical solution adopted in the present invention is: noinductive capacitor, comprise aluminum hull and 2 binding posts, the inner chamber top of this aluminum hull is provided with rubber spacer, bottom is provided with fuse, and this fuse connects this 2 binding posts by wire, the outer cover of described aluminum hull is provided with the aluminum barrel of lower openings, between this aluminum barrel and this aluminum hull, be provided with foam concrete layer, and after bending inwards, the edge at the lower openings place of this aluminum barrel forms flanging, this flanging card has Aluminum cover, simultaneously, the upper surface of this aluminum barrel has explosionproof hole, the lower surface of this Aluminum cover is provided with the cross reinforcement of downward protrusion, and, this aluminum barrel upper end external stability has 2 ceramic cushion blocks, these 2 binding posts are individually fixed on these 2 ceramic cushion blocks.
The advantage that the present invention has is: the impact causing while occurring breaking is less.Even if breaking appears in noinductive capacitor of the present invention, the energy that its content outwards discharges can greatly be absorbed by foam concrete, thereby the impact causing is less.Even if content still has leaking of certain energy, also must outwards release by this explosionproof hole, be equivalent to guide the path of thing of leaking, then further reduce the impact of breaking and causing.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that the master of embodiments of the invention looks half sectional view (not shown Section line);
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the upward view of Fig. 1.
In figure: 10, aluminum hull; 20, rubber spacer; 30, fuse; 40, binding post; 50, aluminum barrel, 51, flanging, 52, Aluminum cover, 521, reinforcement, 53, explosionproof hole; 60, foam concrete layer; 70, ceramic cushion block.
Embodiment
Embodiment, is shown in shown in Fig. 1 to Fig. 3: noinductive capacitor, comprises 10 and 2 binding posts 40 of aluminum hull.The inner chamber top of this aluminum hull 10 is provided with rubber spacer 20, bottom is provided with fuse 30, and this fuse 30 connects this 2 binding posts 40 by wire.Further say, the outer cover of this aluminum hull 10 is provided with the aluminum barrel 50 of lower openings.Between this aluminum barrel 50 and this aluminum hull 10, be provided with foam concrete layer 60.And, after bending inwards, the edge at the lower openings place of this aluminum barrel 50 forms flanging 51, and these flanging 51 cards have Aluminum cover 52.; in the preparation; first aluminum hull 10 (having comprised the parts such as rubber spacer 20, fuse 30 wherein) is put in this aluminum barrel 50 from the lower openings of this aluminum barrel 50; filled and process concrete in the gap of this aluminum barrel 50 and this aluminum hull 10 afterwards; treat that foam concrete solidifies, form foam concrete layer 60, last; place Aluminum cover 52 in the lower end of this foam concrete layer 60, the edge of the lower openings of this aluminum barrel 50 is bent inwards after forming flanging 51 this Aluminum cover 52 is blocked.Meanwhile, the upper surface of this aluminum barrel 50 has explosionproof hole 53.The lower surface of this Aluminum cover 52 is provided with the cross reinforcement 521 of downward protrusion.So-called cross reinforcement refers to 2 reinforcements that intersect vertically each other, and this reinforcement can be by forming after punching press on Aluminum cover 52.And these aluminum barrel 50 upper end external stabilities have 2 ceramic cushion blocks 70, these 2 binding posts 40 are individually fixed on these 2 ceramic cushion blocks 70.Like this, even if there is the situation of breaking, the energy that the content of this capacitor outwards discharges can greatly be absorbed by this foam concrete layer 60, thereby the impact causing is less.Even if content still has and leaks, also must outwards release by this explosionproof hole 53, be equivalent to guide the path of thing of leaking, then further reduce the impact of breaking and causing.
Capacitor is widely used at present, and other structure and principle are same as the prior art, repeat no more here.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
