Abstract
The invention discloses a kind of iron-core reactor stretching screw assembling structures, including stretching screw, upper metal clip, lower metal clip, nut and the T-shaped pad of insulation, the stretching screw both ends are connected separately with metal clip and lower metal clip, and the lower end of the upper end of the upper metal clip and lower metal clip is respectively equipped with nut；The T-shaped pad that insulate is equipped between the lower metal clip and stretching screw；The top of the T-shaped pad of insulation is located at the upper end of lower metal clip；Insulation plain cushion is equipped between the nut and lower metal clip；Spring washer is additionally provided between the nut and upper metal clip；Between the spring washer and upper metal clip, and it is equipped with plain cushion between nut and insulation plain cushion, the iron-core reactor of the present invention fastens assembling structure with stretching screw, by changing locations of structures of the T-shaped pad of insulation on stretching screw, so that the T-shaped pad of insulation is not subject to tighten pulling force, T-shaped the phenomenon that geing existing fragmentation discard of insulating is avoided, ensure that the reliability of product.
Description
Technical field
The present invention relates to a kind of stretching screw assembling structure more particularly to a kind of stretching screw dresses for iron-core reactor
Distribution structure.
Background technology
Reactor is also inductor, and the certain space range that a conductor will be occupied by it when being powered generates magnetic field,
So the electric conductor of all energy current-carrying has perception in general sense, however the inductance for the long straight conductor that is powered is smaller, produced
The not strong therefore practical reactor in magnetic field be that conducting wire is coiled into helical form of tubes, claim air reactor；Sometimes for allowing this spiral shell
Spool has the inductance of bigger, iron core, referred to as core type reactor is just inserted into solenoid, during air reactor is generally used for
Small-capacity product, and high-capacity reactor is generally iron-core reactor.
Stretching screw is designed in current core type reactor, on the one hand effect is ensured on when reactor is run
On the other hand the air gap and fitted position stablized between lower yoke and stem are the connecting assembly load-bearing as entire reactor
And the effect of assembling fastening；In use in order to reduce the stray loss of reactor to the greatest extent, it should avoid allowing the metal of upper and lower iron yoke
Circuit be connected with screw rod is drawn to form electromagnetism in folder, therefore, in the structure design of iron-core reactor, stretching screw with it is upper and lower any
There must be felt pad between metal clip and T-shaped pad insulation of insulating separates（Its structure is as shown in Figure 1）, but hair in use
Existing, when stretching screw is tightened to certain torque, and when the specified value of torque has not yet been reached, the T-shaped pad that insulate can be because of pressure-bearing mistake
There is the phenomenon that fragmentation greatly so that the stray loss of iron-core reactor increases, and affects the stability of iron-core reactor operation.
Invention content
For above-mentioned technical problem, the purpose of the present invention is：It proposes one kind and avoids T-shaped pad fragmentation of insulating, protect
Demonstrate,prove the stable iron-core reactor stretching screw assembling structure of iron-core reactor.
What the technical solution of the present invention was realized in：A kind of iron-core reactor stretching screw assembling structure, packet
Stretching screw, upper metal clip, lower metal clip, nut and the T-shaped pad of insulation are included, the stretching screw both ends are connected separately with
The lower end of metal clip and lower metal clip, the upper end of the upper metal clip and lower metal clip is respectively equipped with nut；It is described
It is lower that the T-shaped pad that insulate is equipped between metal clip and stretching screw；The top of the T-shaped pad of insulation is located at the upper of lower metal clip
End.
Preferably, insulation plain cushion is equipped between the nut and lower metal clip.
Preferably, it is additionally provided with spring washer between the nut and upper metal clip.
Preferably, it is equipped with plain cushion between the spring washer and upper metal clip and between nut and insulation plain cushion.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：
A kind of iron-core reactor stretching screw assembling structure of the present invention program, insulate it is T-shaped pad be located at stretching screw with
Between lower metal clip, and the top for the T-shaped pad that insulate is in the upper end of lower metal clip, so that the T-shaped pad of insulation is tensing spiral shell
It is not subject to tighten pulling force during bar stress, avoids T-shaped the phenomenon that geing existing fragmentation discard of insulating, reduce the spuious of iron-core reactor
Loss ensure that the stability of iron-core reactor operation.
Description of the drawings
Technical solution of the present invention is described further below in conjunction with the accompanying drawings：
Structure diagram of the attached drawing 1 for the iron-core reactor stretching screw assembling structure of the prior art；
Structure diagram of the attached drawing 2 for the iron-core reactor stretching screw assembling structure of the present invention；
Wherein：1st, stretching screw；2nd, nut；3rd, upper metal clip；4th, lower metal clip；5th, insulate plain cushion；6th, it insulate T-shaped
Pad；7th, spring washer；8th, plain cushion.
Specific embodiment
Illustrate the present invention below in conjunction with the accompanying drawings.
A kind of iron-core reactor stretching screw assembling structure of the present invention as shown in Figure 2, including tensing spiral shell
Bar 1, upper metal clip 3, lower metal clip 4, nut 2 and the T-shaped pad 6 of insulation, 1 both ends of stretching screw are connected separately with gold
Belong to folder 3 and lower metal clip 4, the upper end of the upper metal clip 3 and the lower end of lower metal clip 4 are respectively equipped with nut 2；Institute
It states and the T-shaped pad 6 that insulate is equipped between lower metal clip 4 and stretching screw 1；The top of the T-shaped pad 6 of insulation is located at lower metal clip
4 upper end；Insulation plain cushion 5 is equipped between the nut 2 and lower metal clip 4；Between the nut 2 and upper metal clip 3 also
Equipped with spring washer 7；Plain cushion 8 is equipped between the spring washer 7 and upper metal clip 3 and between nut 2 and insulation plain cushion 5.
A kind of iron-core reactor stretching screw assembling structure of the present invention program, the T-shaped pad 6 that insulate are located at lower metal clip
Between 4 and stretching screw 1, and the top for the T-shaped pad 6 that insulate is located at the upper end of lower metal clip 4, and the T-shaped pad 6 that insulate in this way is tensing
It is not subject to tighten pulling force during 2 stress of screw rod, avoids the T-shaped pad 6 of insulation and the phenomenon that fragmentation occur, reduce iron-core reactor
Stray loss ensure that the stability of iron-core reactor operation.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
