Abstract
The present utility model belongs to a novel casting conductor, buckling edge grooves are arranged on peripheral walls of two ports of a contact pedestal of a conductor pedestal, one end of a plum blossom contacting finer is fitted inside the buckling edge grooves, the other end of the plum blossom contacting finer is arranged outside the two ports of the contact pedestal, a spring ring is arranged on the outer wall of the plum blossom contacting finger, a shielding cover is wrapped outside the spring ring at intervals, and the shielding cover is fixed on periphery of the two ports. By adopting the conductor, holding force on a conductive rod can be reduced, load and friction coefficient of transmission machinery can be reduced, service life of a grounding switch is enhanced, and the conductor has advantages of simple structure, small and compact volume, reliability and safety, good stability, low costs and long service life.
Description
Technical field
The utility model belongs to a kind of novel foundry goods conductor.
Background technology
As shown in Figure 1, H-GIS three station isolation earthing switch conductors formerly electrically contact design and are 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.Conducting rod operates in the bracelet type spring.Facts have proved that 6 bracelet type springs are too big to the power of holding tightly of conducting rod; Need bigger mechanism's operating work, conducting rod 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 conducting rod serious to both coefficients of friction of the power of holding tightly large increase of conducting rod simultaneously, influences the contact and the useful life of three station isolation earthing switch.
Summary of the invention
The purpose of the utility model is a kind of novel foundry goods conductor of design, can alleviate the power of holding tightly to conducting rod, 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.
For this reason; The utility model mainly is made up of the conductor seat, on conductor seat upper contact head seat two-port periphery wall, is provided with card along groove, and an end of plum blossom fingertip fits in card along in the groove; The other end of plum blossom fingertip is positioned at outside the contact base two-port; Plum blossom fingertip outer wall is provided with spring coil, and the outer spacer of spring coil is provided with radome from bag, and radome is fixed on the two-port periphery.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 contact base two-port is higher than the inner face with the contact base two-port that belongs to.The said structure design has realized the purpose of the utility model.
The utility model can alleviate the power of holding tightly to conducting rod, reduces the load and the coefficient of friction of gearing, also has simple in structurely the useful life of having improved earthed switch, and compact volume is little, and is safe and reliable, good stability, the low advantage with long service life of cost.The utility model also makes original casting mould reopen, and only on the basis of original blank, carries out machine work, and the profile that processes the conductor seat gets final product, and has saved the expense of die sinking again.The utility model has reduced electric interface, so reduced loop resistance, and also beneficial to reducing temperature rise.

Embodiment
To shown in Figure 4, a kind of novel foundry goods conductor mainly is made up of 2 of conductor seats like Fig. 1.On conductor seat upper contact head seat two-port 8 periphery walls, be provided with card along groove 3, card is provided with fixing screw hole 4 along the inboard contact base wall of groove, is used to connect fixed mask cover 7.One end of plum blossom fingertip 6 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.The other end of plum blossom fingertip is positioned at outside the contact base two-port.Plum blossom fingertip outer wall is provided with spring coil 5, can on plum blossom fingertip outer wall, be provided with 3 spring grooves by spacing distance, and 3 spring coil cards crouch in 3 spring grooves.The effect of spring coil is that the plum blossom fingertip is pressed solidly on the conducting rod periphery wall, 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 conducting rod extruding.Radome is fixed on the two-port periphery, and radome is through being fixed on screw in the fixing threaded hole on the two-port periphery.Obviously, the corresponding conducting rod of radome termination is provided with and supplies its hole of passing.
As shown in Figure 4, 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 contact base two-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 conducting rod periphery wall better.
When conducting rod when plum blossom fingertip inner face moves; The plum blossom fingertip is depressed and can be contacted better with the conducting rod periphery wall in the receipts of spring coil; Not only increase conductivity, and make the plum blossom fingertip more moderate to the power of holding tightly of conducting rod, mechanism's operating work reduces; Reduce the load and the coefficient of friction of gearing, prolonged the useful life of electrical equipment.
In a word, the utility model can alleviate the power of holding tightly to conducting rod, reduces the load and the coefficient of friction of gearing; Improved the useful life of earthed switch, also had simple in structurely, compact volume is little; Safe and reliable, good stability, cost hangs down the advantage with long service life.
