Abstract
The utility model relates to a composite alternating current capacitor with up and down arrangement of core groups. The capacitor comprises a shell, upper and lower core groups arranged in the shell, and an insulating baffle plate used for separating the upper core group and the lower core group. The periphery of an upper end of the insulating baffle plate is provided with an upper positioning sleeve which protrudes upward and is used for positioning the upper core group. The insulating baffle plate is provided with two leading wire through holes. The periphery of a lower end of a leading wire through hole is provided with an insulated boss which protrudes downward. According to the composite alternating current capacitor, carrying out an insulation operation of a metal spraying leading surface manually is not needed, an assembly speed is fast, efficiency is high, assembly quality consistency is good, polar shell voltage withstanding performance can be raised, and the capacitor is suitable for mass production.
Description
Technical field
The utility model relates to a kind of AC capacitor, specifically a kind of core group compound AC capacitor setting up and down
Background technology
Present general CBB65 type composite AC electric container, three leading-out terminals are arranged on the cover plate, be provided with two capacitor core group setting up and down in its housing, isolate with an insulating barrier between two core groups, have two lead hole passing through for lower core group two lead-in wires on the insulating barrier, be provided with the upper positioning sleeve that raises up, is used for upper core group location around the insulating barrier upper end.Because two core groups are totally one public terminal exit, for avoiding short circuit or creepage, need effective isolation between two the non-common port metal spraying of core group lead surfaces.Usually adopt the effect that just can reach insulation about metal spraying lead surface 30 circles of plastic film and Pressure sensitive adhesive tape parcel core group bottom.Because the capacitor core group diameter differs, this operation can not mechanized operation, can only take manual operations, and assembly difficulty is large, wastes time and energy inefficiency.Quality conformance is not high, and utmost point shell is withstand voltage and utmost point shell insulation resistance waste product high.Rework rate is high, and cost allowance is very big.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of core group compound AC capacitor setting up and down, has advantages of that assembly manipulation is easy, percent defective is low, can reduce the capacitor manufacturing cost.
The utility model has adopted following technical scheme: comprise housing, upper and lower core group in the housing is set, and the insulating barrier that is used for separating upper and lower core group, be provided with the upper positioning sleeve that raises up, is used for upper core group location around the insulating barrier upper end, have two lead hole on the insulating barrier, be provided with the insulation boss to lower convexity around lead hole lower end.
The non-common port lead-in wire of lower core group is passed by the lead hole in the insulation boss, so that the creepage distance between the upper and lower core group metal spraying lead surface increases, upper and lower core group does not need to adopt plastic film and Pressure sensitive adhesive tape parcel capacitor core group bottom metal spraying lead surface to insulate, thereby can adopt the machine assembling, assembling speed is fast, efficient is high, and the assembly quality high conformity.
A preferred version of the present utility model is: be provided with around the insulating barrier lower end to lower convexity, be used for lower positioning sleeve to lower core group location.Lower positioning sleeve is set guarantees insulation distance between lower core group metal spraying lead surface and the housing, improve utmost point shell withstand voltage properties.
The utility model is by increasing the up and down creepage distance between the core group metal spraying lead surface, do not need the manual insulation operation of carrying out the metal spraying lead surface, thereby can adopt the machine assembling, assembling speed is fast, efficient is high, and the assembly quality high conformity, can also improve utmost point shell withstand voltage properties, be applicable to produce in enormous quantities.And simple in structure, easily processing.

Fig. 3 is the upward view of Fig. 2.
Embodiment
By shown in Figure 1, the utility model comprises housing 1, is arranged on the upper and lower core group 2,3 in the housing 1, cover plate 5 and be fixed on three leading-out terminals 6 on the cover plate 5, and one of them leading-out terminal is public terminal; Insulating barrier 4 is arranged between the upper and lower core group 2,3.
The insulating barrier structure is provided with the upper positioning sleeve 41 that raises up, is used for upper core group 2 location as shown in Figures 2 and 3 around the insulating barrier upper end, be provided with to lower convexity around the insulating barrier lower end, be used for lower positioning sleeve 42 to lower core group 3 location.Have the insulation boss 45 that is provided with around two lead hole 43,44, one lead hole 44 lower ends to lower convexity on the insulating barrier.
During assembling, the non-common port lead-in wire of lower core group 3 is passed by the lead hole 44 in the insulation boss 45, so that the creepage distance between the upper and lower core group 2,3 non-common port metal spraying lead surface increases, upper and lower core group does not need to adopt plastic film and Pressure sensitive adhesive tape parcel capacitor core group bottom metal spraying lead surface to insulate.Increase the height of insulation boss 45, can effectively prolong the creepage distance between upper and lower core group 2, the 3 metal spraying lead surfaces.Take CBB65 type composite AC electric container as example, for guaranteeing enough creepage distances between upper and lower core group 2, the 3 metal spraying lead surfaces, the height of insulation boss 45 should be not less than 3mm.
