Abstract
The utility model relates to the technical field of a capacitor, in particular to a metalized film capacitor with a leading-out wire welded by terminals. The utility model comprises a cap. The upper part of the cap is provided with a terminal. The terminal is welded with a leading-out wire. The utility model is characterized in that epoxy resin is encapsulated outside the welding part of the terminal and the leading-out wire. The utility model solves the technical problems that the terminal in the existing product needs to be designed with large volume or surface area, which increases the cost of the product; and the existing product needs to be arranged with the structures of a safety cap, a protective circle (seal ring) and a protective sleeve (binding wire belt), which further increases the cost of the product. The utility model can also reduce the complexity of manufacturing technology.
Description
Technical field
The utility model relates to the capacitor technology field, especially a kind of metallic film capacitor with the lead-out wire that welds with terminal.
Background technology
The structure of existing metallic film capacitor is such: it comprises a shell, and upper and lower positioning sleeve is installed in the enclosure, is provided with fuse and impregnant between upper and lower positioning sleeve; 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 lid upper end has terminal, and 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.During use, terminal is inserted circuit get final product.
But, in some circuit structure owing to there is not the interface of terminal, therefore, can only be by realizing the access of capacitor with the lead-out wire of terminal welding.And in order to protect the fail safe of lead-out wire and terminal weld, it comprises the structure as Fig. 1: be provided with volume terminal C1, the C2 of big (or surface area is bigger) in the lid C upper end of capacitor A, the end of two lead-out wire B1, B2 is connected with terminal C1, C2 by welding manner respectively, and the other end then can connect the circuit of capacitor application; Two lead-out wire B 1, B2 are set among the protective casing B jointly; The lid C of this capacitor A goes up further to cover and establishes a safety head D; this safety head D one side has a through wires hole D1; this through wires hole D1 can make the protective casing B that is arranged with lead-out wire B1, B2 pass; in order to prevent that lead-out wire is damaged and to guarantee fail safe in the safety head D, around through wires hole D1, be provided with guard ring E.In the said structure, draw the position and directly be subjected to outside big pulling force for preventing product, two lead-out wire B1, B2 fix by binding band F.
But above-mentioned capacitor arrangement but has following defective:
1, consider the firm welding of terminal and lead-out wire, therefore, the volume of terminal or surface area need design greatlyyer, have therefore increased the cost of product.
2, in order to protect terminal and lead-out wire weld part, also need to be provided with the structure of safety head, guard ring, protective casing (or RVV), binding band, not only increase the complexity of manufacture craft, but also further increased the cost of product.
In view of the foregoing, we must make architecture advances to existing product.
The utility model content
The purpose of this utility model is to provide a kind of metallic film capacitor with the lead-out wire that welds with terminal; solve the volume of the terminal in the existing product or surface area need design the bigger cost that increases product; and the structure that safety head, guard ring, protective casing (or RVV), binding band need be set further increased the cost techniques problem of product, and reduced the complexity of manufacturing process.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of metallic film capacitor, it comprises a lid, and the lid upper end is provided with terminal, and this terminal welds lead-out wire respectively, it is characterized in that: the weld part covering of this terminal and lead-out wire is equipped with epoxy resin.
Described metallic film capacitor is characterized in that: this lid upper end is groove, and this terminal is arranged in the groove, and epoxy encapsulation is in groove.
Described metallic film capacitor is characterized in that: this lead-out wire is sheathed in the protective casing (or RVV).
Described metallic film capacitor is characterized in that: this lead-out wire is sheathed in the binding band.
Described metallic film capacitor is characterized in that: this capacitor comprises a shell, and upper and lower positioning sleeve is installed in the enclosure, is provided with fuse and impregnant between upper and lower positioning sleeve; Last positioning sleeve top in the shell is provided with a lid, has the perforation of lead-out wire and explosion-proof line on the lid, also has corresponding perforation on this on the positioning sleeve; The lid upper end has terminal, and 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.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model is compared with existing product, and the volume of terminal and surface area can dwindle, and has therefore saved material cost;
2, the utility model is compared with existing product, can save the structure of safety head, guard ring, binding band, has not only reduced material cost, but also has simplified manufacturing process.
