The utility model proposes a kind of enclosuring structure in addition, and it comprises oil filler point and seal closure.The edge of oil filler point scrolls up, and molten tin bath is warded off in formation.Seal closure is made by the toughness material, and it can be pressed into oil filler point, and the back-off shape corresponding with warding off molten tin bath is arranged in its position, edge.
Preferably, be provided with the negative drawing structure in the middle of the described seal closure.
Preferably, the described outside of warding off molten tin bath also is provided with a projective structure.
With respect to prior art, the utlity model has following advantage:
1, oil filler point of the present utility model edge scrolls up, and cooperates and ward off molten tin bath, and it is inboard and cause and get rusty to prevent effectively that the end tin from flowing into oil filler point.
2, seal closure of the present utility model has very thin thickness, thereby cheap.
3, be provided with the negative drawing structure in the middle of the seal closure of the present utility model, not only can play the effect that strengthens toughness, can also save the consumption of face tin greatly, reduce the manufacturing cost of high-voltage capacitor.
4, the utility model need not use instruments such as hammer when sealing, and just seal closure can be pressed in the oil filler point with hand, can not cause the situation of case shell depression, makes profile more attractive in appearance.
Certainly, implement arbitrary product of the present utility model and must not necessarily need to reach simultaneously above-described all advantages.

Embodiment
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 3, it is a kind of embodiment schematic appearance of the utility model high-voltage capacitor.The cabinet shell 31 of this high-voltage capacitor is provided with enclosuring structure 32, and enclosuring structure 32 comprises oil filler point and seal closure again.Oil filler point is used for to the inner oiling of high-voltage capacitor, and seal closure is used for being welded on oil filler point after oiling finishes, and seals this oil filler point.The enclosuring structure 32 of present embodiment have be difficult for getting rusty, good looking appearance, advantage that cost is low.
Below oil filler point and seal closure are carried out concrete introduction, see also Fig. 4 and Fig. 5, Fig. 4 is the vertical view of a kind of embodiment oil filler point of the utility model, and Fig. 5 is the profile of A-A position among Fig. 4.This oil filler point center is a manhole 41, scrolls up in its position, edge, and forms one and ward off molten tin bath 42, is used for warding off when sealing into end tin.In the arranged outside of warding off molten tin bath 42 projective structure 43 is arranged, be used to stop that end tin flows out wards off molten tin bath 42.
See also Fig. 6 and Fig. 7, Fig. 6 is the vertical view of a kind of embodiment seal closure of the utility model, and Fig. 7 is the profile of B-B position among Fig. 6.This seal closure is made by the toughness material, and as being stamped to form by taggers tin, it has very thin thickness, thereby cost is lower.On seal closure and with the through hole 41 corresponding positions of oil filler point, be provided with concave configuration 61, and concave configuration 61 and through hole 41 interference fit, it is used for seal closure is sticked into oil filler point.The outside of concave configuration 61 with ward off molten tin bath 42 corresponding positions and be provided with back-off structure 62, be used for being welded on and ward off in the molten tin bath 42 by scolding tin.Be provided with a negative drawing structure 63 in the inboard of concave configuration 61, it has played toughness that increases concave configuration 61 and the effect of saving scolding tin.
Before sealing, as shown in Figure 8, in warding off molten tin bath 42, ward off into end tin 81, because the existence of projective structure 43, make end tin can not flow out laterally, the position, edge owing to oil filler point scrolls up again, so end tin 81 also can not flow into inboard from oil filler point, prevent the situation of getting rusty in the oil filler point inboard effectively, also guaranteed concentrating and welding effect of end tin.
Ward off after the end tin, seal closure is pressed in the oil filler point, as shown in Figure 9, because seal closure has good toughness, therefore just seal closure can be pressed in the oil filler point with hand and can not cause the depression of case shell, and make concave configuration 61 to be stuck in well in the through hole 41.Simultaneously, back-off structure 62 can be buckled in and ward off in the molten tin bath 42.By face tin 91 that seal closure and oil filler point welding is fixing then.Especially,, therefore can save the consumption of face tin 91, that is to say the manufacturing cost that has reduced high-voltage capacitor integral body because be provided with negative drawing structure 63 in the centre of seal closure.And negative drawing structure 63 also can play the effect of supporting concave configuration 61, and concave configuration 61 can more closely be buckled in the through hole 41.
Above-described structure and annexation are a kind of preferred implementation only, but do not limit the utility model with this, and any high-voltage capacitor with the utility model identical function structure all should be in protection range.For example, through hole can be arranged to shapes such as square, triangle; Seal closure also can be made by the material that has toughness arbitrarily except steel plate; Various epireliefs and recessed size all can be adjusted according to actual needs flexibly.
The utility model has also proposed a kind of enclosuring structure, and the enclosuring structure of its structure and aforementioned high-voltage capacitor is identical, does not repeat them here.It should be noted that this enclosuring structure except on the shell that is applied to high-voltage capacitor, also applicable to other structure of container, if also produced same technique effect when being used for other container, all should be in protection range of the present utility model.
The utility model is provided with at the oil filler point edge and wards off molten tin bath, and it is inboard and cause and get rusty to prevent effectively that the end tin from flowing into oil filler point.And seal closure has very thin thickness, thereby cost is lower, is provided with the negative drawing structure in the middle of it, can save the consumption of face tin greatly.
More than disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, any those skilled in the art can think variation, all should drop in the protection range of the present utility model.
