Abstract
The utility model provides a fixing device used for connecting a grounding wire of a secondary terminal port of a high-voltage mutual inductor, and relates to a device for connecting the grounding wire of the secondary terminal port of the high-voltage mutual inductor so that a problem of lack of the device which is small in volume and capable of firmly fixing the grounding wire at the secondary terminal port in the prior art is solved. A magnet is fixed on one end of a conducting rod, and a hook is fixed on the other end of the conducting rod. Concave arc surfaces of two arc-shaped supporting sheets are opposite to each other in arrangement. The conducting rod is vertically arranged between the two arc-shaped supporting sheets. The concave arc surface of each arc-shaped supporting sheet and the side wall of the conducting rod are fixedly connected via at least two springs. One end, which is close to the conducting rod, of a convex arc surface of each arc-shaped supporting sheet is fixedly connected with an arc-shaped convex stand. The device is used for fixedly connecting the grounding wire of the secondary terminal port of the high-voltage mutual inductor.
Description
Technical field
The utility model 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 because secondary terminals rim of the mouth is also less than adult's little finger nail cover, 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, earth connection is entangled on screw lateral wall, then screw is installed in secondary terminals rim of the mouth, this method not only can not ensure that earth connection tangles firmly, in high-voltage mutual inductor debug process, earth connection easily comes off, be difficult for finding, in the time that high-voltage mutual inductor carries out ground connection debugging, high-voltage mutual inductor damaged, and tease earth connection on lateral wall due to screw, screw can not effectively be tightened; Another kind method is that earth connection one end is fixed on Small clamp, then 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 the relative secondary terminals of Small clamp rim of the mouth is very large, cause high-voltage mutual inductor in debug process, the Small clamp being clipped on secondary terminals rim of the mouth produces the mutual interference of undesirable mutual electromagnetic inductance phase with other secondary terminals rims of the mouth, affect the debugging of high-voltage mutual inductor, so it is little and can make earth connection be fixed on the firm device in secondary terminals rim of the mouth to be badly in need of now a kind of volume.
Utility model content
The purpose of this utility model is to provide a kind of for connecting the fixture of high-voltage mutual inductor secondary terminals rim of the mouth earth connection, and to solve, in prior art, to 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 utility model is to address the above problem the technical scheme of taking to be: described fixture of the present utility model comprises conducting rod, magnet, crotch, two arc support chips and at least four springs,
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 utility model compared with prior art has following beneficial effect: of the present utility model a kind of little for connecting the fixture contour structure size of high-voltage mutual inductor secondary terminals rim of the mouth earth connection, and easy installation and removal, can all extend in secondary terminals rim of the mouth, two arc support chip 2-0 withstand the inwall in secondary terminals rim of the mouth under the effect of spring 3-0 elastic force, the magnet 1-1 on conducting rod 1-0 top holds the screw in secondary terminals rim of the mouth, prevent that arc support chip 2-0 from producing the slip of relative secondary terminals rim of the mouth inwall, arc boss 2-1 has reduced the contact area of arc support chip 2-0 and secondary terminals rim of the mouth inwall, thereby increase the support pressure of two arc support chip 2-0 to secondary terminals rim of the mouth inwall, effectively ensure the support of two arc support chip 2-0 to secondary terminals rim of the mouth inwall, and the 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, crotch 1-2 firmly catches on earth connection.
Use device of the present utility model to carry out in the debug process of high-voltage mutual inductor, the relative saving 30% of installation set time in earth connection and secondary terminals rim of the mouth, causes 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 utility model, and Fig. 2 is vertical view of the present utility model, and Fig. 3 is that fixture of the present utility model is installed to the cutaway view in secondary terminals rim of the mouth.
Embodiment
Embodiment one: illustrate in conjunction with Fig. 1 to Fig. 3, the described fixture of present embodiment comprises conducting rod 1-0, 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, crotch 1-2 is fixed on the other end of conducting rod 1-0, the cancave cambered surface of two arc support chip 2-0 is oppositely arranged, conducting rod 1-0 is vertically arranged between two arc support chip 2-0, between the cancave cambered surface of each arc support chip 2-0 and the sidewall of conducting rod 1-0, be fixedly connected with by least two spring 3-0, the described one end near conducting rod 1-0 on the convex globoidal of arc support chip 2-0 is connected with arc boss 2-1.
Embodiment 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 angle Joints of the cancave cambered surface of an arc support chip 2-0, 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 that of the present utility model to be connected and fixed device fixing more reliable, meet and use needs.
In present embodiment, undocumented technical characterictic is identical with embodiment one.
