Abstract

The utility model discloses a transformer framework structure which comprises an intermediate tube and baffles symmetrically arranged at two ends of the intermediate tube, fixed seats are arranged at the bottom ends of the baffles, the fixed seats are fixed together with a machine board through screws, furthermore, a positioning column is arranged on one side of each fixed seat, and positioning holes are correspondingly arranged on the machine board. When in assembly, the screws are inserted into the machine board and screwed into the screw holes of the fixed seats, different models of self-tapping screws or matched screws and nuts can be selected according to different product fixation strengths, and then the self-tapping screws or the matched screws and nuts are screwed and fixed, thereby lightening the complexity of a manufacture procedure and an installation process, reducing time cost on mould opening of raw materials and manual work, reducing the occupation area and space of a product on the machine board, improving the utilization ratio of the product on the machine board, and enhancing the use competitiveness of the product.

Description

A kind of transformer framework structure

Technical field

The utility model relates to the transformer technology field, particularly a kind ofly is convenient to fix, and the skeleton of the firm transformer of structure.

Background technology

At present, industry is produced through transformer commonly used high frequency transformer, generally is mainly Switching Power Supply power transfer transformer and low-frequency transformer (general silicon steel sheet transformer).Switch Power Transformer generally is used for the PCB plug-in unit, and its mounting means is generally on plastic skeleton plugs in steel wire PIN, and its effect both can be used as the pin of conduction, simultaneously also as plug-in unit in PCB, through wave soldering stove scolding tin fixed product.

But for the bigger power transformer product of volume, because general CP line strength can not satisfy instructions for use, for good stationary transformer, improve unfailing performance, in design and actual production, present common solution is for to wrap a bonding plastic feet at the plastic skeleton line again, even adds a metal frame in the entire product outside, and on base or metal frame several screw holes of processing, be fixed on the machine plate with screw rod and nut screwed hole by base or metal frame.It is bigger that this scheme preferably resolves volume, the installation of the power transformer product that weight is bigger, but, this kind solution is with respect to common plug-in unit transformer, increased installation and process complexity, taken bigger machine plate area and volume, cost rises, be unfavorable for guest's demand, reduced the competitiveness of product.

The utility model content

The purpose of this utility model is to provide installation simple transformer framework structure.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of transformer framework structure, and the baffle plate that comprises intervalve and be symmetricly set on the intervalve two ends, the baffle plate bottom is provided with holder, passes through the screw organic plates on the holder.

Further, described holder one side is provided with reference column, and correspondence is provided with location hole on the machine plate.

The beneficial effects of the utility model are: during assembling with screw insertion machine plate and screw among the screw of holder, can select the self-tapping screw of different model or supporting screw and nut for use according to the difference of product constant intensity, and then it is tightened fixing, alleviated the complexity of processing procedure and installation process, die sinking and labor hour cost save material, reduce area occupied and the space of product on the machine plate, improved the utilance of product on the machine plate, strengthened the use competitiveness of product.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation at another visual angle of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

With reference to Fig. 1, shown in Figure 2, a kind of transformer framework structure, the baffle plate 2 that comprises intervalve 1 and be symmetricly set on intervalve 1 two ends, baffle plate 2 bottoms are provided with a plurality of holders 3, offer screwed hole on the holder 3, correspondence is provided with screw hole on the machine plate 4, thereby machine plate 4 can spin by screw 6 and be fixed on the holder 3.With screw 6 insertion machine plates 4 and screw among the screwed hole of holder 3, can select the self-tapping screw of different model or supporting screw and nut for use according to the difference of product constant intensity, and then it be tightened fixing during assembling.

In addition, holder 3 one sides are arranged with reference column 5 in parallel, correspondence is provided with location hole 7 on the machine plate 4, distance between holder 3 and the reference column 5 and location hole 7 equate with distance between the screw hole, thereby, when machine plate 4 was fixed on the baffle plate 2, reference column 5 embedded location hole 7, makes machine plate 4 more firm with being connected of baffle plate 2.

The utility model has alleviated the complexity of processing procedure and installation process, and save material die sinking and labor hour cost have reduced area occupied and the space of product on the machine plate, have improved the utilance of product on the machine plate, have strengthened the use competitiveness of product.

The foregoing description is illustrative principle of the present utility model and effect thereof only; and the embodiment of part utilization; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
