Description
Technical field
The utility model relates to a kind of improved transformer structure.
Background technology
The coil form transformer is one of modal project in the existing power transformer product, and it uses history to surpass one more than century.Also because use for a long time and demand, so the coil form transformer has many improvement so far, in the hope of better application.Yet, no matter developing and which kind of form, it is consistent that the principle of coil form transformer remains.
Aforementioned coil form transformer is a principle of utilizing electric energy and magnetic energy transformation induction, with two groups of coil windings on the housing of ccontaining common iron core (core).These two groups of coils generally are divided into the first siding ring that connects power end, and the second siding ring that connects load end.When first siding ring connects AC power, the electric current that passes through in this coil can produce magnetic flux change in iron core, and the second siding ring of the other end can produce the alternating current of another same frequency because of induction.And the relation of induced voltage is the coil turn ratio that depends on two groups of coils.If the second siding ring number of turn is greater than first siding ring, then output voltage can become step-up transformer greater than input voltage; Otherwise less than first siding ring, then output voltage can become step-down transformer less than input voltage as if the second siding ring number of turn.
Therefore, coil is one of most important assembly of traditional transformer undoubtedly.Except the quality of wire rod itself, coiling also is considerable work.Especially for some small-sized step-down transformers, consider its effect and effect demand factor, its employed secondary side coiling is superfine lead, as long as the application of force is improper or when surpassing stress and bearing a little, fracture promptly may take place and causes afunction or carbonization short circuit.
For this reason, for conventional transformer structure as shown in Figure 5, it has housing 3, this housing 3 is provided with primary side winding slot 31 and secondary side winding slot 32, be arranged with secondary side coiling 42 on this secondary side winding slot 32, and an end that makes this secondary side coiling 42 extends to terminal 312 places in housing 1 outside via primary side winding slot 31, then again in this primary side winding slot 31 outside the winding primary side wind the line 41, to obtain complete transformer device structure.
The winding structure of this traditional transformer has following problem:
1. this secondary side coiling 42 is generally thinner lead, must stride across primary side winding slot 31 during its work, carries out the work of primary side coiling 41 again.So, thinner secondary side coiling 42 can be subjected to the compressing of primary side coiling 41, is easy to produce fracture and the problem of damage.
2. for increasing coiling intensity, this secondary side coiling 42 can several thinner lead overstrikings through twisting thread of boundling, make this secondary side coiling 42 in the junction of twisting thread section, can form suddenly to twist thread 421 by thin chap.Yet these 421 positions of twisting thread are easy to stress and concentrate and the generation fracture.Especially when being subjected to primary side and winding the line 41 outside windings, the easier fracture.
Therefore, traditional transformer must be very careful when carrying out primary side coiling 41 work, in order to avoid cause secondary side coiling 42 to be ruptured because of the application of force improperly.So not only influence operating efficiency, reduce and produce yield.And because of the secondary side of this fracture place coiling 42 is to be hidden in the primary side coiling 41, when the problem of generation and be not easy to be tested out.
In addition, ditto described, through the secondary side of the overstriking of twisting thread coiling 42, it is twisted thread and 421 unprocessedly promptly strides across primary side winding slot 31 and carry out winding in secondary side winding slot 32.So thick, the thin end of this secondary side coiling 42 can winding mutually secondary side winding slot 32 in, cause the layer short circuit problem easily and cause transformer to burn.
Summary of the invention
Main purpose of the present utility model is to provide a kind of improved transformer structure, and promptly it is provided with buffering area to hold the head of twisting thread that is formed by secondary side lead boundling, avoids this head rupture of twisting thread to influence main transformer function, and the function of energy stabilizing transformer.
Another purpose of the present utility model is to provide a kind of improved transformer structure, and the head that is about to twist thread is configured in the buffering area, so even twist thread the head rupture problem, also can differentiate in real time easily and start therefore position, and then remove barriers.
A purpose more of the present utility model is to provide a kind of improved transformer structure, and its secondary side coiling can not be subjected to the direct compressing of primary side coiling, reduces the chance of fracture, more increases the stability of power transformer product.
His purpose of the present utility model is to provide a kind of improved transformer structure, and thick, thin end can not take place the coiling of its secondary side twines mutually, thus avoid short circuit problem between genetic horizon, keep the normal use of transformer.
For realizing above purpose, the utility model has been taked following technical scheme: improved transformer structure, mainly include housing, and this surface of shell is provided with adjacent primary side winding slot and secondary side winding slot.This primary side winding slot outside relative with the secondary side winding slot is respectively arranged with lead frame, and this lead frame outside respectively is provided with terminal, is provided with lead district on this primary side winding slot surface, and is provided with buffering area between this primary side winding slot and the adjacent lead frame.Aforementioned surface of shell is arranged with primary side coiling and secondary side coiling, this secondary side end that winds the line is walked around the primary side winding slot via this lead district, and in this buffering area, this secondary side coiling boundling is twisted thread and overstriking, be fixed on the relative position of this primary side terminal at last.After treating that this secondary side coiling winding is finished, this primary side coiling is then moved in the winding of primary side winding slot.The coiling process of being undertaken by aforementioned structure, this secondary side lead can not be subjected to outside directly compressing of primary side coiling, make it can not produce fracture, and the head system that twists thread of this secondary side coiling is hidden in the buffering area, more can reduce because of the stressed improper fracture result who causes.
The utility model compared with prior art has following advantage:
1. the primary side coiling can not take place and break the problem that the secondary side coiling produces the coiling fracture and then causes transformer to damage in Stability Analysis of Structures of the present utility model, can improve the transformer quality, increases the service life.
2. the utility model is with the secondary side segmentation winding that winds the line, even transformer generation problem, also identification is fast put in order and started because of the place, and carries out suitable disposal or improvement.
