Specific embodiment
Below in conjunction with attached drawing and implement to further illustrate the utility model.
With reference to Fig. 1-Fig. 9, a kind of conductive seat of twin columns rotary open type disconnecting switch, including junction block 1 and small quarter bend 2, small quarter bend 2 is installed in the outer surface of 1 side A of junction block, one end phase of the inner surface and flexible circuit 5 of 1 side A of junction block Even.The contact surface of 5 three of junction block 1, small quarter bend 2 and flexible circuit offers bolt mounting holes 11, and three passes through bolt 8 Through connected.The front end face B and rear end face E of small quarter bend 2 are provided with screw rod mounting hole 10, and small quarter bend 2 is loaded on inside conducting rod 3, Small quarter bend 2 is connected by the way that the first screw rod 9 of screw rod mounting hole 10 is passed through to run through with conducting rod 3, and the other end of flexible circuit 5 leads to Cross the second screw rod(It is not shown in figure)It is connected with 4 lower end of conductive shaft, wire connection terminal 6 is installed on 4 upper end of conductive shaft, wire connection terminal 6 Pass through third screw rod with conductive shaft 4(It is not shown in figure)It is connected.1 lower part of junction block is equipped with boss 12, and 1 top of junction block offers Axis hole 13, another axis hole 14 is offered on boss 12, and conductive shaft 4 passes through the axis hole 13 on 1 top of junction block and the axis hole of boss 12 14.First insulating sleeve 7-1 in the axis hole 13 on 1 top of junction block is housed, the second shaft insulation is installed in the axis hole 14 of boss 12 It covers 7-2, the first insulating sleeve 7-1 and the second insulating sleeve 7-2 and is set on 4 periphery of conductive shaft.
The axis hole of boss 12 is stretched out in the lower end of conductive shaft 4, alternatively, the lower end bottom surface of conductive shaft 4 and the axis hole 14 of boss 12 Bottom surface is concordant.When the axis hole of boss 12 is stretched out in the lower end of conductive shaft 4, the length of 12 axis hole of boss is stretched out in the lower end of conductive shaft 4 Less than the height of boss, when being connected in favor of the bottom surface for ensuring junction block 1 with porcelain vase upper flange surface, 1 convex platform of junction block Presence so that there are gap between the bottom surface of conductive shaft 4 and porcelain vase upper flange surface, when can prevent the conductive shaft 4 from rotating and porcelain Bottle upper flange mantle friction ensures normal rotation of the conductive shaft 4 in the first insulating sleeve 7-1 and the second insulating sleeve 7-2.
Angle between small quarter bend 2 upper surface C and side D is 90 degree or 65 degree.
Before use, junction block 1 is installed on porcelain vase upper flange, the bottom surface of junction block 1 is connected with porcelain vase upper flange surface, Junction block 1 and the same central shaft of porcelain vase.Meanwhile wire connection terminal 6 is connected with external wire clamp.When disconnecting switch works, wire connection terminal 6 Since the pulling force by external wire clamp is fixed, so the conductive shaft 4 connected with wire connection terminal 6 is also fixed;Keeping apart During closing switching on and off, junction block 1 rotates, due to flexible circuit 5, the first insulating sleeve 7-1 and the second insulating sleeve 7-2 Presence so that junction block 1 can be relatively rotated around conductive shaft 4, rotation of the rotation of junction block 1 with moving conductive rod 3, so as to have Conducive to disconnecting switch is prevented during switching on and off, since wire connection terminal 6 is caused conducting rod " suppressing dead " by external wire clamp pulling force Situation.
With reference to Fig. 6, when the angle between small quarter bend 2 upper surface C and side D is 90 °, can be achieved after being assembled with junction block 1 Molding double-column horizontal rotary open type disconnecting switch conductive seat.
For double-column horizontal rotary open type disconnecting switch, since two porcelain vases of disconnecting switch are set in numeric state It puts, two porcelain vases are mutually parallel.To ensure that conducting rod is horizontal, between conducting rod central shaft ZX1 and porcelain vase central shaft Angle is 90 °;Due to junction block and the same central shaft of porcelain vase, so between conducting rod central shaft ZX1 and junction block central shaft ZX2 Angle is also 90 °.As shown in Figure 1, conducting rod central shaft ZX1 is parallel with quarter bend upper surface C small in conducting rod, junction block central shaft ZX2 is parallel with quarter bend side D small in conducting rod, therefore the angle between small quarter bend 2 upper surface C and side D is also 90 °.
With reference to Fig. 7, when small 2 upper surface of quarter bend and flank angle are 65 °, can be achieved after being assembled with junction block 1 molding double Column V-type rotary open type disconnecting switch conductive seat.
It is conductive to ensure if the included angle between two porcelain vases of disconnecting switch for V-type rotary open type disconnecting switch Bar is horizontal, and the angle between conducting rod central shaft ZX1 and porcelain vase central shaft is 90 ° of-φ/2;Due to junction block and porcelain vase Same central shaft, so the angle between conducting rod central shaft ZX1 and junction block central shaft ZX2 is also 90 ° of-φ/2.It can by Fig. 1 Know, conducting rod central shaft ZX1 is parallel with quarter bend upper surface C small in conducting rod, junction block central shaft ZX2 and small quarter bend in conducting rod Side D is parallel, therefore the angle between small quarter bend 2 upper surface C and side D is also 90 ° of-φ/2.
Since existing V-type rotary separation switch is in manufacture, the included angle between two porcelain vases of disconnecting switch is 50 °, so, the angle between small quarter bend 2 upper surface C and side D is also 90 ° -50 °/2=65 °.If V-type is rotatably kept apart Close manufacture when two porcelain vases between included angle be not 50 °, then the angle between small quarter bend 2 upper surface C and side D also with Variation, meet 90 ° of-φ/2.
By choosing in different length Fig. 3, junction block that length is represented by x in different height Fig. 6 and Fig. 7, it is high The small quarter bend represented by y is spent, it can be achieved that the disconnecting switch of molding a variety of current classes after junction block and small quarter bend are assembled Conductive seat, so as to substitute the conductive seat casting of plurality of specifications, save casting mould cost.
The through-current capability of the current class of disconnecting switch, as disconnecting switch current-carrying part, through-current capability and junction block and The passage section of small quarter bend is proportional, and when passage section is bigger, through-current capability is bigger, otherwise smaller.Junction block it is through-flow Section=length × height, when height is fixed, the size of passage section can be changed by changing the length of junction block.Small quarter bend it is through-flow Section=length × height, when length is fixed, the size of passage section can be changed by changing the height of small quarter bend.
Using the utility model, existing conductive seat casting structure is eliminated, equipped with junction block and small quarter bend, passes through small square Pipe is assembled with junction block, it can be achieved that the disconnecting switch conductive seat of molding twin columns rotary open type.When small quarter bend upper surface With flank angle be 90 ° when, with junction block assemble after can be achieved molding double-column horizontal rotary open type disconnecting switch conduction bottom Seat;Molding double-column V-shaped can be achieved when it is 65 ° to intercept small quarter bend upper surface with flank angle, after assembling with junction block to rotate Open-type isolating switch conductive seat.
A kind of preferred embodiment of the utility model is discussed in detail above.The specific embodiment is only It is the core concept for being used to help understand the utility model.It should be pointed out that those of ordinary skill in the art, not Be detached from the utility model principle under the premise of, can also to the utility model, some improvement and modification can also be carried out, these improve and repair Decorations also belong to the protection domain of the utility model claims.
