Abstract
The utility model belongs to a bus butt joint shielding cover, which is in an annular shape. A fixed screw hole is arranged on the inner side of the shielding cover, an inner bent edge bending inwards is positioned on the outer side of the shielding cover, the diameter of the inner bent edge is large than that of a movable contact, the inner side of the shielding cover and a fixed contact are fixed together through a screw, a clamp edge groove is arranged on the periphery of an end port of the fixed contact, one end of a plum blossom touch finger is matched in the clamp edge groove, the other end of the plum blossom touch finger is positioned outside the fixed contact, a spring ring is arranged on the outer wall of the plum blossom touch finger, and the shielding cover is arranged outside the spring ring at interval. The bus butt joint shielding cover can improve shielding effect of all butt joint contacts, can reduce tightly-holding force on the movable contact, reduces load and friction coefficient of transmission machinery, prolongs service life of a ground connection switch and ahs the advantages of being simple in structure, small and compact in volume, safe and reliable, good in stability, low in cost and long in service life.
Description
Technical field
The utility model belongs to a kind of bus butt joint radome.
Background technology
As shown in Figure 1, H-GIS three station isolation earthing switch conductors, each butt contact shield effectiveness is poor, poor stability.In addition, formerly electrically contact design and be employed in contact base two-port inside and establish 6 bracelet type springs of assembling in 1,6 bracelet type of 6 bracelet type spring grooves spring groove.Moving contact operates in the bracelet type spring.Facts have proved that 6 bracelet type springs are too big to the power of holding tightly of moving contact; Need bigger mechanism's operating work; Moving contact is moved in bracelet type spring, thereby increase the transmission intensity of first order insulation power transmission shaft, increase the load of gearing; Bracelet type spring causes the infringement of bracelet type spring and moving contact serious to both coefficients of friction of the power of holding tightly large increase of moving contact simultaneously.The contact and the useful life of above-mentioned defective effect three station isolation earthing switch.
Summary of the invention
The purpose of the utility model is a kind of bus butt joint of design radome, can improve the shield effectiveness of each butt contact, can alleviate the power of holding tightly to moving contact; Reduce the load and the coefficient of friction of gearing, in the useful life of having improved earthed switch, also have simple in structure; Compact volume is little; Safe and reliable, good stability, cost hangs down the advantage with long service life.
For this reason, the utility model mainly is made up of moving contact and fixed contact, and radome is annular; Fixing threaded hole is established in the radome inboard, and the radome outside is provided with the interior curved edge of inwardly bending into, and the diameter on interior curved edge is greater than the moving contact diameter; The radome inboard is fixed as one through screw and fixed contact; Fixed contact port periphery wall is provided with card along groove, and an end of plum blossom fingertip fits in card along in the groove, and the other end of plum blossom fingertip is positioned at outside the fixed contact port; Plum blossom fingertip outer wall is provided with spring coil, and the outer spacer of spring coil is provided with radome from bag.Described plum blossom fingertip is the annular contact that several independently petal contacts are formed.The described plum blossom fingertip inner face that is positioned at outside the fixed contact port is higher than the inner face with the contact base two-port that belongs to.Described radome is annular.Described moving contact front end is T-shaped.The said structure design has realized the purpose of the utility model.
The utility model can improve the shield effectiveness of each butt contact, can alleviate the power of holding tightly to moving contact, reduces the load and the coefficient of friction of gearing; Improved the useful life of earthed switch; Also have simple in structurely, compact volume is little, and is safe and reliable; Good stability, cost hangs down the advantage with long service life.

Fig. 2 is the structural representation of the utility model.
Fig. 3 is the plum blossom fingertip sketch map of the utility model.
Embodiment
To shown in Figure 3, a kind of bus butt joint radome mainly is made up of moving contact 6 and 1 of fixed contact like Fig. 1.Radome 5 is annular, and fixing threaded hole 9 is established in the radome inboard, and the radome outside is provided with the interior curved edge 8 of inwardly bending into, and the diameter on interior curved edge is greater than the moving contact diameter.The radome inboard is fixed as one through screw 2 and fixed contact.Fixed contact port periphery wall is provided with card along groove 10, and an end of plum blossom fingertip 4 fits in card along in the groove, and the plum blossom fingertip can only serve as mobile outside axially along groove with card like this, and can not break away from card along in the groove.Plum blossom fingertip outer wall is provided with spring coil 3; Can on plum blossom fingertip outer wall, be provided with 3 spring grooves by spacing distance; 3 spring coil cards crouch in 3 spring grooves, and the effect of spring coil is that the plum blossom fingertip is pressed solidly on the plug periphery wall of moving contact front end, to increase conductivity.The outer spacer of spring coil is provided with radome from bag, at interval depend on that apart from width the plum blossom fingertip receives the distance that outwards rises after the plug extruding.The other end of plum blossom fingertip is positioned at outside the fixed contact port.
Described plum blossom fingertip is the annular contact that several independently petal contacts are formed.The described plum blossom fingertip inner face that is positioned at outside the fixed contact port is higher than the inner face with the contact base two-port that belongs to, and is beneficial to the plum blossom fingertip and contacts with the plug periphery wall better.
Described radome is annular.Described moving contact front end is T-shaped.The moving contact front end is provided with the plug 7 of diameter less than moving contact.
When the plug of moving contact front end when plum blossom fingertip inner face moves; The plum blossom fingertip is depressed and can be contacted better with the moving contact periphery wall in the receipts of spring coil, not only increases conductivity, and makes the plum blossom fingertip more moderate to the power of holding tightly of plug; Mechanism's operating work reduces; Reduce the load and the coefficient of friction of gearing, and the shield effectiveness of radome butt contact is good, has prolonged the useful life of electrical equipment.
In a word, the utility model can improve the shield effectiveness of each butt contact, can alleviate the power of holding tightly to moving contact; Reduce the load and the coefficient of friction of gearing, in the useful life of having improved earthed switch, also have simple in structure; Compact volume is little; Safe and reliable, good stability, cost hangs down the advantage with long service life.
