Abstract
For connecting a fixture for high-voltage mutual inductor secondary terminals rim of the mouth earth connection, it relates to a kind of for connecting the device of high-voltage mutual inductor secondary terminals rim of the mouth earth connection. To solve, to lack a kind of volume in prior art little and can make earth connection be fixed on the problem of the firm device in secondary terminals rim of the mouth, magnet is fixed on one end of conducting rod, crotch is fixed on the other end of conducting rod, the cancave cambered surface of two arc support chips is oppositely arranged, conducting rod is vertically arranged between two arc support chips, between the cancave cambered surface of each arc support chip and the sidewall of conducting rod, be fixedly connected with by least two springs, the described one end near conducting rod on the convex globoidal of arc support chip is connected with arc boss. The present invention is used for being fixedly connected with high-voltage mutual inductor secondary terminals rim of the mouth earth connection.
Description
Technical field
The present invention relates to a kind of for connecting the device of high-voltage mutual inductor secondary terminals rim of the mouth earth connection.
Background technology
High-voltage mutual inductor is carried out in debug process, the secondary terminals rim of the mouth ground connection of high-voltage mutual inductor need to be debugged, but byAlso less than adult's little finger nail cover in secondary terminals rim of the mouth, make secondary terminals rim of the mouth ground connection very inconvenient. Prior art has two kinds,A kind of is that the screw in secondary terminals rim of the mouth is unloaded, and earth connection is entangled on screw lateral wall, then screw is installed to secondary terminalsIn rim of the mouth, this method not only can not ensure that earth connection tangles firmly, and in high-voltage mutual inductor debug process, earth connection is easily de-Fall, be difficult for finding, when high-voltage mutual inductor carries out ground connection when debugging, high-voltage mutual inductor is damaged, and due to the outside of screwOn wall, tease earth connection, screw can not effectively be tightened; Another kind method is that earth connection one end is fixed on Small clamp, soAfter Small clamp is clipped on secondary terminals rim of the mouth, because mostly the secondary terminals rim of the mouth of high-voltage mutual inductor is to distribute in groups, and Small clamp phaseVery large to secondary terminals rim of the mouth, cause high-voltage mutual inductor in debug process, be clipped in Small clamp on secondary terminals rim of the mouth and other twoInferior terminal mouth produces the mutual interference of undesirable mutual electromagnetic inductance phase, affects the debugging of high-voltage mutual inductor, thus be badly in need of now a kind of volume little andCan make earth connection be fixed on the firm device in secondary terminals rim of the mouth.
Summary of the invention
The object of this invention is to provide a kind of for connecting the fixture of high-voltage mutual inductor secondary terminals rim of the mouth earth connection, to solveIn prior art, lack a kind of volume little and can make earth connection be fixed on the problem of the firm device in secondary terminals rim of the mouth.
The present invention addresses the above problem the technical scheme of taking to be: described fixture of the present invention comprises conducting rod, magneticIron, crotch, two arc support chips and at least four springs,
Magnet is fixed on one end of conducting rod, and crotch is fixed on the other end of conducting rod, the cancave cambered surface phase of two arc support chipsTo arranging, conducting rod is vertically arranged between two arc support chips, the cancave cambered surface of each arc support chip and the side of conducting rodBetween wall, be fixedly connected with by least two springs, the described one end near conducting rod on the convex globoidal of arc support chip is connected withArc boss.
The present invention compared with prior art has following beneficial effect: one of the present invention is used for connecting high-voltage mutual inductor secondary terminalsThe fixture contour structure size of rim of the mouth earth connection is little, and easy installation and removal, can all extend into secondary terminals rim of the mouthIn, two arc support chip 2-0 withstand the inwall in secondary terminals rim of the mouth, conducting rod 1-0 under the effect of spring 3-0 elastic forceThe magnet 1-1 on top holds the screw in secondary terminals rim of the mouth, prevents that arc support chip 2-0 from producing relative secondary terminals rim of the mouth inwallSlip, arc boss 2-1 has reduced the contact area of arc support chip 2-0 and secondary terminals rim of the mouth inwall, thereby has increasedTwo arc support chip 2-0 support pressure to secondary terminals rim of the mouth inwall, has effectively ensured that two arc support chip 2-0 are to twoThe support of inferior terminal mouth inwall, and shelves eaves 4-2 in secondary terminals rim of the mouth blocks the arc boss 2-1 of arc support chip 2-0,The bottom of conducting rod 1-0 is provided with crotch 1-2, and crotch 1-2 firmly catches on earth connection.
Use device of the present invention to carry out in the debug process of high-voltage mutual inductor, when the installation in earth connection and secondary terminals rim of the mouth is fixedBetween relatively save 30%, cause the impaired probability of high-voltage mutual inductor relatively to reduce by 60% because the earth connection in secondary terminals rim of the mouth comes off.
Brief description of the drawings
Fig. 1 is structural representation axonometric drawing of the present invention, and Fig. 2 is top view of the present invention, and Fig. 3 is fixture of the present inventionBe installed to the cutaway view in secondary terminals rim of the mouth.
Detailed description of the invention
Detailed description of the invention one: illustrate in conjunction with Fig. 1 to Fig. 3, the described fixture of present embodiment comprises conducting rod1-0, magnet 1-1, crotch 1-2,, two arc support chip 2-0 and at least four spring 3-0,
Magnet 1-1 is fixed on one end of conducting rod 1-0, and crotch 1-2 is fixed on the other end of conducting rod 1-0, two arcsThe cancave cambered surface of support chip 2-0 is oppositely arranged, and conducting rod 1-0 is vertically arranged between two arc support chip 2-0, each arcBetween the cancave cambered surface of shape support chip 2-0 and the sidewall of conducting rod 1-0, be fixedly connected with by least two spring 3-0, arc props upOn the convex globoidal of support sheet 2-0, be connected with arc boss 2-1 near described one end of conducting rod 1-0.
Detailed description of the invention two: illustrate in conjunction with Fig. 1 to Fig. 3, the quantity of the described spring 3-0 of present embodiment is eight,Four spring 3-0 are one group, one end of every group of spring 3-0 respectively with four angles of the cancave cambered surface of an arc support chip 2-0Joint, the other end of described one group of spring 3-0 respectively with the sidewall Joint of conducting rod 1-0.
Eight spring 3-0 have increased the support force of two arc support chip 2-0 to secondary terminals rim of the mouth inwall, make company of the present inventionConnect fixture fixing more reliable, meet and use needs.
In present embodiment, undocumented technical characterictic is identical with detailed description of the invention one.
Operation principle
First one end of earth connection is entangled in to crotch 1-2 upper, clamps two arc support chip 2-0 with two fingers, by thisBright device inserts in the secondary port 4-0 of high-voltage mutual inductor, when the magnet 1-1 of conducting rod 1-0 withstands in secondary terminals rim of the mouthScrew 4-1 time unclamp finger, the arc boss 2-1 of each arc support chip 2-0 props up the madial wall of secondary port, twoThe annular shelves eaves 4-2 of inferior port blocks arc boss 2-1, and magnet 1-1 holds the screw 4-1 in secondary port simultaneously, fromAnd realize being fixedly connected with of secondary port and earth connection.
