A kind of collar aperture on high-voltage board, it is at least 3 including sleeve pipe hole number, and connected between adjacent casing hole provided with otch, institute's collar aperture is in polygonized structure, and at least there are two symmetry axis, the outer circumference in described sleeve pipe hole is additionally provided with screw mounting hole, sleeve pipe plug-in-sleeve hole and is connected by screw mounting hole with high-voltage board.Angle between described polygonized structure adjacent edge is more than 90 °.Described otch is straight line elongated slot.Described screw mounting hole is provided with 4 groups, and screw mounting hole group is uniformly distributed on collar aperture center.The beneficial effects of the utility model：1. the utility model is simple in construction, manufacturing cost is low.2. these are to change original single shape, now it is changed into multiple shapes, increased break-in power, efficiency block, using effect be quick, easy to process, improve mould and service life of a machine that ellipse needs punching to be molded for more than 100 times, make into polygon only need to ten several times can be with.
Description
Technical field
The collar aperture that the utility model belongs on collar aperture technical field, more particularly to a kind of high-voltage board.
Background technology
Collar aperture on existing high-voltage board, is all ellipse, and this structure needs more than 100 ability processing and forming of punching
Difficulty, high processing costs.
The content of the invention
The utility model is directed to problem above, and the utility model is the collar aperture on a kind of high-voltage board, and these are to change
Single shape originally, is now changed into multiple shapes, and increased break-in power, efficiency block, using effect is quick, easy to process, carry
High mould and service life of a machine.
The utility model solves the technical scheme that its technical problem is used：
A kind of collar aperture on high-voltage board, including sleeve pipe hole number are at least between 3, and adjacent casing hole provided with otch
Connection, institute's collar aperture is in polygonized structure, and at least there are two symmetry axis, and the outer circumference in described sleeve pipe hole is additionally provided with screw peace
Fill in hole, sleeve pipe plug-in-sleeve hole and be connected by screw mounting hole with high-voltage board.
Angle between described polygonized structure adjacent edge is more than 90 °.
Described otch is straight line elongated slot.
Described screw mounting hole is provided with 4 groups, and screw mounting hole group is uniformly distributed on collar aperture center.
The screw mounting hole quantity of the screw mounting hole group is one or two.
Described sleeve pipe hole number is three, and three collar aperture centers are point-blank.
Described sleeve pipe hole number is 4, and described sleeve pipe hole connects to form " Contraband " shape.
The beneficial effects of the utility model：
1. the utility model is simple in construction, manufacturing cost is low.2. these are to change original single shape, now it is changed into many
Individual shape, increased break-in power, efficiency block, using effect be quick, easy to process, improve mould and service life of a machine that is ellipse
Circle needs punching to be molded for more than 100 times, make into polygon only need to ten several times can be with.
Brief description of the drawings：
Fig. 1 is the structural representation of the utility model embodiment 1；
Fig. 2 is the structural representation of the utility model embodiment 2.
Embodiment：
As shown in Figure 1-2, the collar aperture 1 on a kind of high-voltage board, including the quantity of collar aperture 1 are at least 3, and adjacent casing
Connected between hole 1 provided with otch 2, institute's collar aperture 1 is in polygonized structure, and at least there are two symmetry axis, described sleeve pipe hole 1
Outer circumference is additionally provided with screw mounting hole 3, sleeve pipe plug-in-sleeve hole 1 and is connected by screw mounting hole 3 and high-voltage board.
Angle between described polygonized structure adjacent edge is more than 90 °.
Described otch 2 is straight line elongated slot.Incision design can not only ensure the intensity of collar aperture, moreover it is possible to which effective clearance covers
The eddy-current loss of pore, improves service life.
Described screw mounting hole 3 is provided with 4 groups, and 3 groups of screw mounting hole is uniformly distributed on the center of collar aperture 1.
The quantity of screw mounting hole 3 of 3 groups of the screw mounting hole is one or two.
Embodiment 1：As shown in figure 1, the quantity of described sleeve pipe hole 1 is three, and three centers of collar aperture 1 are in straight line
On.
Embodiment 2：As shown in Fig. 2 the described quantity of collar aperture 1 is 4, the connection of described sleeve pipe hole 1 forms " Contraband " shape.
The beneficial effects of the utility model：
1. the utility model is simple in construction, manufacturing cost is low.2. these are to change original single shape, now it is changed into many
Individual shape, increased break-in power, efficiency block, using effect be quick, easy to process, improve mould and service life of a machine that is ellipse
Circle needs punching to be molded for more than 100 times, make into polygon only need to ten several times can be with.
