Drawings
FIG. 1 is a schematic structural view of the present invention;
the main reference numerals in the figures have the following meanings:
the sealing structure comprises a wiring terminal 1, a porcelain part 2, a pressing plate 3, a nut 4, a rectangular sealing ring 5, a hexagon socket head cap screw 6, a grounding cover 7 and a sealing gasket 8.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1: the embodiment is a measurement terminal with bolt-up ground cover, including measurement terminal body and ground cover 7, the clamp plate 3 of measurement terminal body is installed on the sleeve pipe through hexagon socket head cap screw 6, the top threaded connection of the terminal 1 of measurement terminal body has nut 4, be provided with rectangular seal ring 5 between the porcelain 2 top in nut 4 and the terminal 1 outside, ground cover 7 cover in the top of measurement terminal body and with the top threaded connection of terminal 1, seal through rectangular seal ring 5 between ground cover 7 and the clamp plate 3 and pass through hexagon socket head cap screw 6 fixed connection.
In the embodiment, an annular boss is formed at the top of the pressing plate 3, a groove matched with the annular boss is formed at the bottom of the grounding cover 7, and the rectangular sealing ring 5 between the grounding cover 7 and the pressing plate 3 is positioned between the bottom of the groove of the grounding cover 7 and the top of the annular boss of the pressing plate 3.
The measuring terminal body is formed by combining a binding post 1, a porcelain piece 2 and a pressing plate 3, wherein the porcelain piece 2 is arranged on the outer side of the binding post 1, and the pressing plate 3 is arranged on the outer side of the porcelain piece 2; in the embodiment, when the terminal is installed, the tail end of a binding post 1 is welded with a tail screen lead, a rectangular sealing ring 5 is tightly pressed on the top of a porcelain piece 2 by a nut 4 on the binding post 1, a pressing plate 3 is installed on a sleeve through an inner hexagon bolt 6, the pressing plate 3 and the sleeve are sealed through a T-shaped sealing gasket 8, a grounding cover 7 is in threaded connection with the top of the binding post 1, and the grounding cover 7 and the pressing plate 3 are sealed through the rectangular sealing ring 5 and are fixedly connected through the inner hexagon bolt 6; when test items such as bushing capacitance are measured, the hexagon socket head cap screw 6 between the grounding cover 7 and the pressing plate 3 is dismounted, and the grounding cover 7 is unscrewed; after the measurement is finished, the grounding cover 7 is tightly and tightly connected to the pressure plate 3 in a sealing way; adopt threaded connection between terminal 1 and the ground connection cover 7 in this embodiment, adopt bolted connection between ground connection cover 7 and the clamp plate 3, adopt rectangle sealing washer 5 to seal between ground connection cover 7 and the clamp plate 3 simultaneously, this kind of dual connection mode has improved measuring terminal overall structure intensity, effectively prevents dust and completely cuts off the steam in the air.
The utility model discloses increased the ground connection cover, sealed and adopt bolted connection through the rectangular seal circle between the clamp plate of ground connection cover and measurement terminal, the fastening leakproofness is good, has avoided the easy condition that wets of measurement terminal overall structure, improves measurement terminal overall structure intensity, guarantees the safe and reliable performance of measurement terminal.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
