Embodiment
Figure 1 shows that the generalized section of the instrument transformer encapsulation fixture that the utility model one embodiment provides.Figure 2 shows that the schematic top plan view of the instrument transformer encapsulation fixture that Fig. 1 provides.
The one that provides the present embodiment is fixed on instrument transformer encapsulating mould, for encapsulating the instrument transformer encapsulation fixture of cast-type mutual inductor, comprises connecting portion 1, stopper section 2 and multiple fixed part 3.One end of connecting portion 1 is fixed on instrument transformer encapsulating mould.Stopper section 2 is arranged at the other end of connecting portion 1, and the cross-sectional width d2 of stopper section is greater than the cross-sectional width d1 of connecting portion.Multiple fixed part 3 joins end to end successively and is fixed on stopper section 2, the cross-sectional width of each fixed part 3 is all less than the cross-sectional width d2 of stopper section, multiple fixed part 3 is coaxially arranged, and along the direction away from stopper section 2, the cross-sectional width of multiple fixed part 3 reduces gradually, and the identical length etc. of multiple fixed part 3.
For better mating different instrument transformer structures, the shape of fixed part 3 is set for circular or square.In the present embodiment, the shape of fixed part 3 is circular, and the quantity arranging fixed part 3 is three.But the utility model is not limited in any way this.
In use, be fixed on by connecting portion 1 in the holddown groove on instrument transformer encapsulating mould, stopper section 2 offsets with the side of holddown groove, plays stop spacing.Multiple instrument transformer with different inner diameters is fixed on multiple fixed part 3.Instrument transformer encapsulating mould matched moulds can complete the encapsulation of the instrument transformer of multiple different size on the position corresponding to a holddown groove simultaneously, has high packaging efficiency, and required cost of labor and power consumption cost are identical with an encapsulation instrument transformer.Therefore also significantly production cost can be reduced.
Along with the quantity of fixed part 3 increases gradually, highly also increase gradually accordingly, required area occupied also constantly becomes large.And when a matched moulds and the fixed part 3 of not all can be used.Therefore, in the present embodiment, each fixed part 3 is set and is hollow structure, and in adjacent two fixed parts 3, internal diameter near the fixed part 3 of side, stopper section 2 is not less than the external diameter of the fixed part 3 away from side, stopper section 2, adjacent two fixed part 3 telescopic connections.
This is arranged so that, user in use can according to the specification choice for use of the instrument transformer of current encapsulation wherein several fixed part 3, not only can meet the encapsulation of the instrument transformer of different size, and there will not be when encapsulating the problem cannot mating encapsulating mould due to excessive height.And further, when not using, user can by mutually nested successively for multiple fixed part 3, and nested rear formation only has the height of a fixed part 3, greatly reduces area occupied, deposits very convenient.
In the present embodiment, on the sidewall of each fixed part 3, equal place, distance two ends is provided with fixing hole, and connector is worn and penetrated connecting hole and fix adjacent two fixed parts 3, realizes the expansion of fixed part 3.Pulling out connector then can shrink nested by multiple fixed part 3.But the utility model is not limited in any way this.
Along with the increase of fixed part 3 quantity, when encapsulating, the active force be applied on stopper section 2 also will increase.To deform because of excessive pressure for avoiding stopper section 2 and even damage, in the present embodiment, in the axis both sides of multiple fixed part 3, the width that stopper section 2 exceeds the position of the fixed part 3 be connected with stopper section 2 is all less than the length of stopper section 2.
And be the intensity improving stopper section 2 further, arrange connecting portion 1, stopper section 2 and first fixed part 3 three in one be connected with stopper section 2 are shaped.This is arranged so that the junction of above-mentioned three parts has better bending tensile strength.And for avoiding the undue concentration of stress to make junction occur fracture, in the present embodiment, arrange the junction of connecting portion 1 and stopper section 2, the equal tool in junction of stopper section 2 and fixed part 3 is arc-shaped outer surface.The setting of arc-shaped outer surface well can disperse the stress of junction, improves bonding strength.
In the present embodiment, for preventing instrument transformer in encapsulation process, instrument transformer is made to rotate around fixed part 3 due to injection pressure.The outer surface of each fixture 3 all arranges spiral 31.This spiral 31 adds the frictional force between fixture 3 and instrument transformer, plays anti-skidding effect.
In sum, by arranging the equal and the first fixed part 3 be connected successively of multiple length on stopper section 2, and the cross-sectional width of multiple fixed part 3 reduces gradually, and when encapsulating, user can fix multiple instrument transformer with different inner diameters on multiple fixed part 3.This instrument transformer is utilized to encapsulate fixture, the encapsulation of the instrument transformer of multiple different size can be completed in a matched moulds process simultaneously, not only increase substantially production efficiency, decreased the frequency of utilization of encapsulating mould simultaneously, extend the useful life of encapsulating mould.
In addition, adjacent two fixed parts 3 telescopic connections are set, user can select the quantity of the fixed part needed according to the specification of the instrument transformer of required encapsulation in use, and by nested for multiple fixed part 3 fixing after being used to complete, greatly reduce taking up room of multiple fixed part 3, be convenient to deposit.
Although the utility model discloses as above by preferred embodiment; but and be not used to limit the utility model; anyly know this those skilled in the art; not departing from spirit and scope of the present utility model; can do a little change and retouching, therefore protection range of the present utility model is when being as the criterion depending on claims scope required for protection.
