The mounting structure of junction block in a kind of transformer
The utility model belongs to technical field of electronic components, is related to a kind of transformer, more particularly in a kind of transformer
The mounting structure of junction block.
Transformer is the device for changing alternating voltage using electromagnetic induction principle, generally comprises two groups and is wound with conducting wire
Coil, and each other inductively to claim to unify, when an alternating current stream is in one of them group coil, in another group of coil
It is middle to induce the alternating voltage with identical frequency, and the voltage swing incuded depends on the journey of the coupling of two coils and magnetic interlinkage
Degree, transformer is the device for converting alternating voltage, electric current and impedance, when being connected with alternating current in primary coil, iron core or magnetic
Just exchange flux is generated in core, makes to induce voltage or electric current in secondary coil.It is more next with the continuous development of transformer industry
More industries and enterprise has applied to transformer, and more and more enterprises enter transformer industry.Its in transformer at present
The installation of junction block is typically all to be connected or be fixed on transformer by wearing screw in junction block, glue by glue
Connected mode needs to wait for the glue solidifies could enter next process in the completed, and hair is easy during the glue solidifies
It is raw so that junction block is shifted due to colliding or tilting between each other, and the mode that screw is connected is typically all to be directly mounted at shell
On damaged transformer shell make its barrier propterty decline.
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, provides a kind of production easy for installation
The mounting structure of junction block during used time is short and the more rational transformer of structure.
The purpose of this utility model can be realized by following technical proposal：The installation knot of junction block in a kind of transformer
Structure, the transformer include coil assembly, iron core, the bottom plate being made of primary coil and secondary coil, the coil assembly around
Three-phase transformer is formed on iron core, the iron core is fixed on bottom plate, and pressing plate, the bottom plate are provided at the top of iron core
It is respectively arranged with the corresponding link block in several positions with the both sides of pressing plate, the center of the link block offers screw hole, and
It is equipped with screw rod by screw hole, which is characterized in that the position on the screw rod between bottom plate and pressing plate is arranged with metal
Casing is located at the top of metal sleeve on the screw rod and is arranged with mounting plate between pressing plate, and the both ends of the screw rod have spiral shell
Line simultaneously makes bottom plate inwardly be compressed with pressing plate and fastens mounting plate by tightening nut, and the outer of the mounting plate is sloped downwardly shape
It it is 120 degree at angle α, the outside of the mounting plate has the mounting groove of integral structure, has installation in the mounting groove
Step is simultaneously arranged with junction block by installation step.
Its technique effect of the mounting structure of junction block is in this transformer：This transformer in an assembling process, by spiral shell
Be arranged metal sleeve on bar, make the both ends of metal sleeve are low to be respectively against bottom plate and pressing plate, and at the top of metal sleeve with pressure
Mounting plate is set between plate, and by making mounting plate fasten in screw rod both ends tightening nut, mounting plate has mounting groove, is installed in group
Junction block is directly set by the installation step card in mounting groove at rear, it is short that installation method simply produces the used time, and effectively avoids
The problem of junction block is easy displacement when traditional glue is pasted, and screw destroys transformer shell when fixing, wherein outside mounting plate
It is sloped downwardly to form 120 degree of angle, the design of the structure can facilitate the on line of junction block.
In above-mentioned transformer in the mounting structure of junction block, the bottom surface of the bottom plate is respectively welded on its four corners
There is foot pad, and the outer ledge of foot pad is globoidal structure.The installation of this transformer can be facilitated to fix by the design of foot pad, by
The design of globoidal structure is extended outwardly through in foot cushion structure can prevent its scuffing to human body.
Compared with prior art, the mounting structure of junction block installs junction block by the design of mounting plate in this transformer
Have the advantages that the production used time easy for installation is short and structure is more reasonable.

Specific implementation mode
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, Figure 2, Figure 3 shows, in this transformer junction block mounting structure, the transformer include by primary coil and
Coil assembly 1, iron core 2, the bottom plate 3 of secondary coil composition, coil assembly 1, which is set around on iron core 2, forms three-phase transformer, iron core
2 are fixed on bottom plate 3, and the top of iron core 2 is provided with pressing plate 4, and the both sides of bottom plate 3 and pressing plate 4 are respectively arranged with several position phases
The center of corresponding link block 5, link block 5 offers screw hole, and is equipped with screw rod 6 by screw hole, is located at bottom plate on screw rod 6
Position between 3 and pressing plate 4 is arranged with metal sleeve 7, is located on screw rod 6 between 7 top of metal sleeve and pressing plate 4 and is arranged with peace
The both ends of loading board 8, screw rod 6 have screw thread and keep bottom plate 3 tight with the inside compression of pressing plate 4 and by mounting plate 8 by tightening nut 9
Gu the outer of mounting plate 8 is sloped downwardly that form angle α be 120 degree, the mounting groove of the outside of mounting plate 8 with integral structure
