Description
Technical field
The present invention relates to the capacitor technology field, especially a kind of safe metallic film capacitor.
Background technology
In order to increase the fail safe of capacitor, industry has been invented the capacitor with explosion-proof performance.Present noinductive capacitor mainly comprises following structure:
Upper and lower positioning sleeve is installed in a shell, between upper and lower positioning sleeve, is provided with fuse and impregnant; Last positioning sleeve top in the shell is provided with a lid, has lead-out wire (comprising explosion-proof line) perforation on the lid, also has corresponding perforation on this on the positioning sleeve.The lead-out wire that the terminal lower end connects is connected with fuse with the perforation that explosion-proof line passes above-mentioned lid and last positioning sleeve; This lid by crimping inside on the shell by press seal in the enclosure.
We know, explosion-proof line draws to such an extent that the explosion-proof performance of straight more then capacitor is good more in the above-mentioned capacitor.But in actual installation and processing process, because in the process of processing shell crimping with the encapsulation lid, lid is easy to processed machinery and takes up and rotate in the lump and then cause explosion-proof line together to turn to non-perpendicular position with lid, thereby causes explosion-proof line effective length to increase.And long explosion-proof line produces short circuit phenomenon easily in processing shell crimping process, has so just caused the decline or the inefficacy of properties of product.
Summary of the invention
The object of the present invention is to provide a kind of safe metallic film capacitor, solve existing noinductive capacitor and in manufacture process, cause explosion-proof line short circuit and long technical problem easily, further strengthen the reliability of capacitor explosion-proof performance.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of safe metallic film capacitor, it comprises that a upper end has the cylinder blanket of opening, and positioning sleeve and following positioning sleeve are installed in the shell, is provided with fuse and impregnant between upper and lower positioning sleeve; Last positioning sleeve top in the shell is provided with a lid, the perforation that has lead-out wire, explosion-proof line on the lid, upward also have corresponding perforation on the positioning sleeve, the lead-out wire that the terminal lower end connects is connected with fuse with the perforation that explosion-proof line passes above-mentioned lid and last positioning sleeve; It is characterized in that: be provided with a location mechanism between this lid and the last positioning sleeve, this lid passes through the inside crimping in shell upper end open place by press seal in the enclosure.
Described safe metallic film capacitor is characterized in that: this detent mechanism comprises the positioning convex column that is arranged at the lid bottom and the position and the corresponding location notch of positioning convex column that are arranged on the positioning sleeve, and this projection just can be fastened in the location notch.
Described safe metallic film capacitor is characterized in that: be provided with sealing gasket between the press seal place of this lid and housing crimping.
Compared with prior art, the invention has the beneficial effects as follows:
1, capacitor of the present invention has explosion-proof performance;
2, the present invention is provided with detent mechanism between last positioning sleeve and lid, this detent mechanism can be guaranteed can not produce mutual rotation between the positioning sleeve and lid on product is when carrying out shell crimping press seal, has avoided explosion-proof line to be provided with long or because positioning sleeve and lid rotate the explosion-proof line short circuit phenomenon that is caused mutually.
