Description

Capacitor sealing structure

Technical Field

The utility model relates to a ultracapacitor system technical field especially relates to a capacitor seal structure.

Background

Supercapacitor means the novel energy storage device between traditional condenser and rechargeable battery, and it had both had the characteristic of condenser quick charge-discharge, had the energy storage characteristic of battery again simultaneously, and prior art has disclosed that the application number is: 201820203850.5, it includes ultracapacitor system module body, parcel insulating layer and the encapsulated layer of parcel in the insulating layer outside in ultracapacitor system module body outside, encapsulated layer is one of epoxy, phenolic resin and silicone resin, and the ultracapacitor system monomer of this ultracapacitor system module links together through the PCB board, and the PCB board is compared with the guide pin among the prior art, and is big with the area of contact of PCB board, is difficult for arousing the short circuit, increases the life of ultracapacitor system module, but the shortcoming lies in: the volume of this ultracapacitor system module's shell is great, the cost is higher, and the heat that ultracapacitor system produced is difficult to give off to the outside easily, especially in intelligent water gauge field, and the water gauge is placed for a long time and is needed to carry out the encapsulating to the shell of ultracapacitor system module at moist below ground to be used for dampproofing and preventing damp, but sealed mode not only makes the heat that electric capacity produced difficult the giving off, but also the consumptive material is consuming time, the improvement cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: the sealing structure of the capacitor is provided for solving the problem that heat is difficult to dissipate after the shell of the traditional super capacitor module is filled with glue.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a capacitor sealing structure, includes insulation support, casing, core package, plug and lead wire, the core package sets up in the inner chamber of casing, the plug sets up in the beam waist department of casing, the arc of casing is sealed and is provided with between the plug and be used for dampproofing damp-proofing filler.

As a further description of the above technical solution:

the lead wire runs through the rubber plug and the filler and extends to the outside of the shell.

As a further description of the above technical solution:

the filler is one of epoxy glue, silica gel, polyurethane glue and resin.

As a further description of the above technical solution:

the thickness of the filler is 1-5 mm.

As a further description of the above technical solution:

the arc-shaped seal of the shell is buckled into the filler.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

the utility model discloses in, every capacitor case's inside all encapsulating has the filler, and the filler can be used to the dampproofing and moisture-proof of condenser self, and two condensers can directly pass through the series connection use between the PCB board, need not to add the shell again and carry out dampproofing and moisture-proof, compare traditional ultracapacitor system module structure simpler, the volume is littleer, heat dispersion is better, and cost reduction makes things convenient for in daily use moreover.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a capacitor sealing structure, including insulation support 1, casing 2, core package 3, plug 4 and lead wire 6, core package 3 sets up in the inner chamber of casing 2, plug 4 sets up in the beam waist department of casing 2, be provided with between the arc department of sealing of casing 2 and plug 4 and be used for dampproofing and moisture-proof filler 5, filler 5 presses on plug 4, plug 4 moves upward or has a small amount of liquid to spill over in preventing the condenser use, filler 5 fills after the inside of casing 2, need to stand half an hour to an hour under 40 ℃ -60 ℃.

Specifically, as shown in fig. 3, the lead 6 extends to the outside of the housing 2 through the rubber plug 4 and the filler 5, and the lead 6 is used for connecting with other components.

Specifically, as shown in fig. 1, the filler 5 is one of epoxy glue, silica gel, polyurethane glue and resin, the thickness of the filler 5 is 1-5 mm, and the filler 5 is used for moisture prevention and moisture prevention of the capacitor.

Specifically, as shown in fig. 2, the arc-shaped seal of the housing 2 is buckled into the filler 5, so that water vapor can be prevented from entering the housing 2 from a gap between the arc-shaped seal and the filler 5.
