Embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

See also Fig. 1, the structural representation of the capacitor core group that it provides for the utility model preferred embodiments.Capacitor core group is applied in the capacitor, and said capacitor core group comprises capacitor body 1, plug 2, Thermal Cutoffs 3, discharge resistance 4, long lead-out wire 5 and short lead-out wire 7.

Plug 2 is housed in the capacitor body 1, and Thermal Cutoffs 3 electrically connects and is housed in the through hole of plug 2 with discharge resistance 4, and an end of Thermal Cutoffs 3, an end of discharge resistance 4, long lead-out wire 5 are Y-connection through connection welding 6.

The opposite end of capacitor body 1 is provided with end face solder joint 1 and end face solder joint 29 respectively; The other end of Thermal Cutoffs 3 is welded on the end face solder joint 29; The other end of discharge resistance 4 is welded on the end face solder joint 1; Short lead-out wire 7 is outside end face solder joint 1 leads to capacitor body 1, and long lead-out wire 5 is outside connection welding 6 leads to capacitor body 1.

Capacitor body 1 is reeled by high temperature resistant high-class product metallization zinc-aluminium composite polypropylene film and is formed, and its coiling axle center is the plug 2 of band through hole.High-temperature resistant membrane has adopted the better polypropylene particles of temperature tolerance, and this particle has added temperature modifier, and ash content increases to some extent, causes isotacticity and the degree of crystallinity of particle to increase, stretched film temperature tolerance better.The capacitor of processing can use at 110 ℃ long-term down.

The first step of said capacitor core group assembling is that each exit with Thermal Cutoffs 3, discharge resistance 4 and long lead-out wire 5 links together through connection welding 6 earlier.

Second step of said capacitor core group assembling does, with Thermal Cutoffs 3, discharge resistance 4 with connect in the through hole that solder joint 6 penetrates plug 2, long lead-out wire 5 passes through hole.Can effectively reduce the volume that capacitor core group is occupied like this.

The 3rd step of said capacitor core group assembling does, another exit of Thermal Cutoffs 3 is welded on the end face solder joint 29, and another exit of discharge resistance 4 is welded on the end face solder joint 1.Like this, capacitor body parallel connection discharge resistance, the Thermal Cutoffs of having connected.

The 4th step of said capacitor core group assembling is will lack lead-out wire 7 and be welded on the end face solder joint 1.This solder joint need connect an end face, discharge resistance 4 and the short lead-out wire 7 of capacitor body 1, in order to guarantee firm welding, needs to increase this solder joint, requires solder joint height greater than 2mm (general solder joint is lower than 1.5mm).
