Abstract

The utility model relates to a fixer for iron core of transformer which comprises a base and an iron core, the base is provided with a horizontal through-hole, a coil is arranged around, the two ends of the base is provided with an end foot; the iron core comprises a left iron core and a right iron core in the same structure which is respectively provided with a convex shaft and a square-shaped frame combined at the circumference of the coil, the convex shaft which is threaded in a through-hole of the base in the left-right direction is arranged inside the coil; the fixer is an iron core fixing box with an opening on one side, the internal wall dimension can match with the external wall dimension of the iron core, the left internal wall and the right internal wall opposed one another on the fixing box are respectively at least provided with a convex point pressing on the left and right iron cores. The utility model to be used can shorten the fabrication period of transformer, the inspection and repairing works on transformer can be facilitated in production process.

Description

The fixture of transformer core

(1) technical field:

The utility model relates to the fixed bin of a kind of fixture of transformer core, particularly a kind of transformer core.

(2) background technology:

The employed transformer of electrion fluorescent tube (as shown in Figures 1 and 2) has for example generally comprised pedestal 1 and iron core 2 these pedestals 1 are provided with cross through hole 11, and periphery is wound with coil 12, the two ends installing end pin 13 of pedestal 1; And iron core 2 includes two left iron core 2a and right iron core 2b that structure is identical, it respectively has a prominent axle 21 and framework 22, and prominent axle 21 respectively is set in the through hole 11 of pedestal 1 by left and right directions, and is positioned at

coil

12, and 22 pairs of synthesizing quadrate frameworks of two frameworks are positioned at the periphery of coil 12.

Two involutory left and right

sides iron core

2a, 2b interfix, and its fixed form generally has two kinds, twine with jelly 3 gummeds (as shown in Figure 3) or with adhesive plaster 4 and close (as shown in Figure 4), remake insulation processing (soak varnish, varnish is the insulation glue of transformer special use) at last.

There is following shortcoming in the said fixing mode of transformer core:

(1), processing operation trouble is time-consuming, obviously increase the number of working processes, and must do admittedly up to jelly with clip clamping iron core before with the jelly gummed and in the gummed process;

(2), jelly is done solid or twine close iron core and finish after, iron core is difficult to take off;

(3), processing operation process in, left and right sides iron core is difficult for aligning, and influences product quality;

(4), twine in the process of closing iron core, transformer is through high-temperature operation, and adhesive plaster gets loose easily with adhesive plaster.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of iron core fixing device of being convenient to load and unload, and it is provided with an iron core fixed bin, after assembling left and right sides iron core on the iron core pedestal, can be fixed on the iron core of the left and right sides by this fixed bin, and it is fixed, and is convenient to subsequent job.

The utility model is taked following concrete structure:

The fixture of transformer core of the present utility model, this transformer includes pedestal and iron core; Pedestal is provided with cross through hole, and periphery is arranged with coil, and the pedestal two ends are provided with the end pin; Iron core includes isostructural left iron core of two-phase and right iron core, and it respectively has a prominent axle and can be to the synthetic square framework that is positioned at coil periphery, and each is set in prominent axle in the through hole of pedestal by left and right directions, is positioned at coil;

This fixture is an iron core fixed bin, and it is the box body that an one side has opening, and its inwall size matches with the outer wall dimension of iron core, but fixed bin about two relative inwalls respectively be provided with the prominent point of at least one packing left and right sides iron core.

Compared with prior art, the utlity model has following effect:

Utilize the fixture of the utility model transformer core, in the time of shortening the worker of transformer, and be convenient in the production process can utilize the position of the inwall correction left and right sides iron core of fixed bin for the upkeep operation of transformer, make it keep aligned condition, to improve the quality of transformer.

Fig. 1: the three-dimensional exploded view of transformer.

Fig. 2: the three-dimensional combination figure of transformer.

Fig. 3: existing schematic perspective view with jelly gummed mode stationary transformer iron core.

Fig. 4: have now and twine the schematic perspective view that closes mode stationary transformer iron core with adhesive plaster.

Fig. 5: fixed bin of the present utility model is covered on the schematic perspective view on the transformer core.

The assembled sectional view of Fig. 6: Fig. 5.

(5) embodiment:

Reaching embodiment in conjunction with the accompanying drawings is described in detail as follows architectural feature of the present utility model:

As Fig. 5 and shown in Figure 6, the fixture of the utility model transformer core, mainly provide a kind of iron core fixed bin 5, fixed bin 5 has the box body 52 of opening 51 for one side, its inwall size cooperates with the outer wall dimension of iron core 2, and two relative inwalls 53 respectively are provided with the prominent point 54 of at least one location usefulness about fixed bin 5.

Transformer of the present utility model and aforementioned transformer are just the same, include pedestal 1 and iron core 2, and the left iron core 2a that iron core 2 includes two same structures draws and right iron core 2b.

The same as described above, on pedestal 1, assemble left and right

sides iron core

2a, 2b, left and right sides iron core promptly can carry out fixed operation by 5 pairs of iron cores of iron core fixed bin of the present utility model 2 during to the synthesizing quadrate framework.That is, fixed bin 1 is fixed in the top and the periphery of iron core 2, at this moment, but two

iron core

2a, 2b about prominent point 54 packings about fixed bin 5 on two inwalls, make its mutual driving fit, and front and back inwall 55 that can fixed bin 5 revises the positions of left and right sides iron

core

2a, 2b automatically, make its alignment, extremely easy, can exempt jelly gummed or adhesive plaster and twine and a large amount of man-hours such as close; Especially in process of production,, also can easily fixed bin 5 be pulled down if when needing to Repair of Transformer, wait maintenance to finish after, can fixed bin 5 be fixed on involutory left and right sides iron core 2a, the 2b according to aforesaid way again, it is fixed, extremely simple and practical.

At last, after with the solid transformer core of fixed bin 5 cover, this transformer promptly forms a container that the end is arranged, can be easily insulating cement such as portion's infusion epoxy resin within it, finish its insulation processing work, make inner all members have more the contraction fixed function.
