Band shell magnetic ring transformer
Technical field
The utility model relates to the technical field of electron rectifier, electronic transformer, is meant a kind of magnetic ring transformer especially.
Background technology
Present rectifier toroidal transformer, its structure comprises a magnet ring, magnet ring surface spraying one deck insulating paint, the magnet ring surface is with the corresponding number of turns of copper cash coiling, to reach the respective electrical performance.In actual use,, influence its internal electron structural arrangement, thereby influence its electrical property, make the entire circuit coupling unstable owing to behind spraying one deck paint the inner suffered stress of magnet ring is increased; Adopt the straight leading foot of copper cash in addition, both be unfavorable for that welding also was unfavorable for installing, and, can have influenced withstand voltage insulation because copper cash directly is wound on the magnet ring surface.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of and need not at magnet ring surface spraying insulating paint, and do not adopt the band shell magnetic ring transformer of the straight leading foot of copper cash.
For addressing the above problem, the technical solution adopted in the utility model is: band shell magnetic ring transformer, comprise magnet ring, also comprise the housing of insulation, magnet ring is arranged on the enclosure interior of insulation, be provided with the coiling hole in the housing, the centre bore of magnet ring is corresponding with the coiling hole, and housing is provided with several pins, and the outside of housing is wound with some groups of copper cash, copper cash passes the outside that the coiling hole is wound on housing, and the end of copper cash is connected with pin.
Described housing comprises two small shells of mutual involutory setting.The structure of described two small shells is identical, and the involutory surface of small shell is provided with draw-in groove and card post, and draw-in groove and card post are symmetrical arranged along the axis of symmetry of involutory surface.
Described housing comprises lower house and cap, and the top of lower house is provided with the magnet ring hole of matching with magnet ring, and the bottom of lower house is provided with pin.
The beneficial effects of the utility model are: above-mentioned band shell magnetic ring transformer, and simple in structure, easy to use.It is placed on magnet ring in the insulation shell, thereby makes the magnet ring surface need not to spray insulating paint, can reduce its suffered stress influence effectively, improves the stability of its electrical property; The housing coiling that it adopts the band pin makes welding easier behind the finished product, it is very easy that whole machine installation also becomes, and Pin locations can not made mistakes; Its magnet ring is enclosed within the housing the inside, and coil all outside housing, can effectively promote withstand voltage dielectric strength between coil and magnet ring, makes withstand voltage insulation safer; This product coiling is succinct, has promoted production efficiency.

Embodiment
Below by specific embodiment the utility model band shell magnetic ring transformer is described in further detail.
As Fig. 1, shown in Figure 2, band shell magnetic ring transformer, the housing 2 that comprises magnet ring 1 and insulation, housing 2 comprises two small shells 21 of mutual involutory setting, the structure of two small shells 21 is identical, as Fig. 3, shown in Figure 4, the involutory surface of small shell 21 is provided with draw-in groove 3 and card post 4, draw-in groove 3 and card post 4 are symmetrical arranged along the axis of symmetry 5 of involutory surface, thereby make 21 pairs of two small shells fashionable, and the match screens of two small shells 21 of realization of draw-in groove 3 and card post 4 is connected, be provided with porose 61 in the small shell 21, two small shells 21 are combined to form a coiling hole 6, and magnet ring 1 is arranged on housing 2 inside of insulation, and the centre bore of magnet ring 1 is corresponding with coiling hole 6, housing 2 is provided with six pins 7, the outside of housing 2 is wound with three groups of copper cash 8, and copper cash 8 passes the outside that coiling hole 6 is wound on housing 2, and the end of copper cash 8 is connected with pin 7.
As Fig. 5, shown in Figure 6, above-mentioned housing 2 also can be another kind of structure, comprise lower house 9 and cap 10, the top of lower house 9 is provided with the magnet ring hole 11 of matching with magnet ring 1, magnet ring 1 is arranged in the magnet ring hole 11, and the bottom of lower house 9 is provided with pin 7, is provided with lower casing body opening 62 in the lower house 9, be provided with cap hole 63 in the cap 10, lower house 9 and cap 10 involutory backs form coiling hole 6 at the middle part.
The beneficial effects of the utility model are: above-mentioned band shell magnetic ring transformer, and simple in structure, easy to use.It is placed on magnet ring 1 in the insulation shell 2, thereby makes magnet ring 1 surface need not to spray insulating paint, can reduce its suffered stress influence effectively, improves the stability of its electrical property; Housing 2 coilings that it adopts band pin 7 make welding easier behind the finished product, it is very easy that whole machine installation also becomes, and can not make mistakes in pin 7 positions; Its magnet ring 1 is enclosed within housing 2 the insides, and coil all outside housing 2, can effectively promote 1 withstand voltage dielectric strength of coil and magnet ring, makes withstand voltage insulation safer; This product coiling is succinct, has promoted production efficiency.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the utility model; Should be pointed out that 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.
