Description
Technical field
Capacitor technology field is the utility model is related to, refers in particular to interior string metallized film capacitor.
Background technology
The quality of capacitor, in addition to detection is weighed with capacity, loss, insulation, pressure-resistant four basic parameters.Its resistance to pulse
Voltge surge and to bear the performances such as size of current be also needed to be considered.The capacitor used in absorbing circuit and resonance circuit
This 2 points with greater need for attention.Because the pole plate of string structure and the connecting end surface drawn are dielectric films in metallization, and the connection
The contact resistance at position is larger, and when adding pulse, the electric current that moment is flowed through is very big, causes fever, and plastic film medium is thermo-labile,
Heat is shunk, and is caused end contact to deteriorate, is made equivalent series resistance bigger, in this way, vicious circle, can lose thin-film capacitor quickly
Effect.
The content of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided a kind of resistance to pulse, insulation, resistance to pressure be good,
The interior string metallized film capacitor of service life length.
To achieve the above object, technical solution provided by the utility model is：Interior string metallized film capacitor, it includes
Have shell and several cores in shell, core stacks gradually arrangement inside the shell from the bottom to top, adjacent core it
Between be equipped with partition, partition is shaped using ceramic material, and partition both ends are equipped with upper and lower perforative pole piece link slot, pole piece connection
Connection sheet is equipped with groove, connection sheet is fabricated to shape using aluminium foil, and connection sheet both ends pass through pole piece link slot and corresponding core pole
Plate connects, and cover top portion is equipped with the extraction pole piece being connected with connection sheet, the gap location between partition, core, shell after connection
Filled with filler.
The connection sheet is fixed on shell inner cavity wall.
The septa thickness is 1-2mm, its surface is equipped with concavo-convex heat conduction line.
The utility model is conducive to heat conduction and heat dissipation after using the above scheme, using partition made of ceramic material, its
Resistance to pulse, insulation, resistance to pressure are good, and partition both ends are contradicted with shell inner cavity wall, make shell shaping performance more preferable, heat conduction line makes heat
Easily disperse, connection sheet heat conduction, the rapid heat dissipation of shape be fabricated to using aluminium foil, can effective holding capacitor device integrality, extend
The service life of capacitance.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the pole piece connecting groove structure schematic diagram of the utility model.
Embodiment
With reference to all attached drawings, the utility model is described in further detail, and the preferred embodiment of the utility model is：Ginseng
Attached drawing 1 and attached drawing 2 are seen, if interior string metallized film capacitor described in the present embodiment includes shell 1 and in shell 1
Dry core 2, core 2 stacks gradually from the bottom to top to be arranged in shell 1, and partition 3,3 thickness of partition are equipped between adjacent core 2
For 1mm, its surface is equipped with concavo-convex heat conduction line, and partition 3 is shaped using ceramic material, and 3 both ends of partition are equipped with and pass through up and down
The pole piece link slot 4 worn, pole piece link slot 4 is interior to be equipped with connection sheet 5, and connection sheet 5 is fixed on 1 internal chamber wall of shell, and connection sheet 5 is adopted
Shape is fabricated to aluminium foil, 5 both ends of connection sheet are connected through pole piece link slot 4 with corresponding 2 pole plate of core, and the top of shell 1 is equipped with
The extraction pole piece 6 being connected with connection sheet 5, the gap location between partition 3, core 2, shell 1 after connection are filled with filler.This reality
Apply example and heat conduction and heat dissipation be conducive to using partition made of ceramic material, its resistance to pulse, insulation, resistance to pressure are good, partition both ends with
Shell inner cavity wall contradicts, and makes shell shaping performance more preferable, and it is scattered that heat conduction line is easier heat, and the company of shape is fabricated to using aluminium foil
Contact pin heat conduction, rapid heat dissipation, can effective holding capacitor device integrality, extend the service life of capacitance.
The embodiment of the above is only the preferred embodiment of the utility model, and the reality of the utility model is not limited with this
Apply scope, therefore the change that all shape, principles according to the utility model are made, it should all cover in the scope of protection of the utility model
It is interior.
