Abstract
The utility model relates to the technical field of power transformers, in particular to a high-frequency transformer framework. The high-frequency transformer framework comprises a frame body, wherein a primary wire winding groove and a secondary wire winding groove are formed in the two ends of the frame body respectively, a connecting part is arranged between the primary wire winding groove and the secondary wire winding groove, the two ends of the connecting part are connected with the primary wire winding groove and the secondary wire winding groove primary, the secondary wire winding groove is provided with a plurality of PINs, and the width T of the secondary wire winding groove is larger than or equal to 6mm. According to the high-frequency transformer framework, due to the fact that the width of the secondary wire winding groove is increased, the safety distance between the primary wire winding groove and the secondary wire winding groove can reach a standard, high voltage abnormity defects are avoided, wire flying is removed in an actual production process, and production efficiency is improved.
Description
Technical field
The utility model relates to power transformer technical field, relates in particular to a kind of high-frequency transformer skeleton.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is elementary winding slot, secondary rolling thread groove and iron core (magnetic core).Major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.By purposes, can be divided into: distribution transformer, power transformer, full-sealed transformer, combined transformer, dry-type transformer, oil-filled transformer, single-phase transformer, furnace transformer, rectifier transformer etc., be usually used in the power supply apparatus such as power supply adaptor.
Existing transformer framework, safe distance between its elementary winding slot and secondary rolling thread groove can be because consider the requirement of cost, material, the safe distance of its elementary winding slot and secondary rolling thread groove is often too small, easily cause the bad defect of high pressure, for fear of this defect, when manufacturing skeleton, usually need secondary rolling thread groove to carry out fly line, but due to fly line complex procedures, and be all manually to operate, very loaded down with trivial details in the actual course of processing, greatly reduce formation efficiency, be not suitable for producing in enormous quantities.
Summary of the invention
The purpose of this utility model is to provide a kind of high-frequency transformer skeleton for the deficiencies in the prior art, the utility model is by increasing the width of secondary rolling thread groove, make the safe distance between elementary winding slot and secondary rolling thread groove reach standard, avoided the bad defect of high pressure, in actual production process, remove this operation of fly line, improved production efficiency.
For achieving the above object, a kind of high-frequency transformer skeleton of the present utility model, comprise support body, the two ends of described support body are respectively arranged with elementary winding slot and secondary rolling thread groove, between described elementary winding slot, secondary rolling thread groove, be provided with a connection piece, the two ends of described connector are connected with secondary rolling thread groove with elementary winding slot respectively, and described secondary rolling thread groove is provided with several PIN pin, and the fore-and-aft distance T of described secondary rolling thread groove is more than or equal to 6mm.
As preferably.Described secondary rolling thread groove is also provided with wrapping post, and described wrapping post arranges with PIN pin is vertical.
As preferably, described wrapping post and secondary rolling thread groove are one-body molded.
As preferably, the width of described secondary rolling thread groove is 8mm.
As preferably, described connector is provided with magnetic core hole, and magnetic core is provided with magnetic core in hole.
The beneficial effects of the utility model: by limiting the width of secondary rolling thread groove, distance between PIN pin in secondary rolling thread group and the PIN pin in elementary coiling group is increased, and one and the vertically disposed wrapping post of PIN pin are set on secondary rolling thread groove, the line that secondary rolling thread groove is pulled out is first walked around wrapping post, again on PIN pin, make the safe distance between elementary winding slot and secondary rolling thread groove reach standard, avoided the bad defect of high pressure, in actual production process, remove this operation of fly line, improved production efficiency.

Fig. 2 is the structural representation at another visual angle of the utility model.
Reference numeral comprises:
1-elementary winding slot 2-secondary rolling thread groove, 21-PIN pin
22-wrapping post, 3-connector, 31-magnetic core hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1 to Figure 2, a kind of high-frequency transformer skeleton, comprise support body, the two ends of described support body are respectively arranged with elementary winding slot 1 and secondary rolling thread groove 2, between described elementary winding slot 1 and secondary rolling thread groove 2, be provided with a connection piece 3, the two ends of described connector 3 are connected with elementary winding slot 1, secondary rolling thread groove 2 respectively, and described secondary rolling thread groove 2 is provided with several PIN pin 21, and the width T of described secondary rolling thread groove 2 is more than or equal to 6mm.
Safe distance between the elementary winding slot 1 of the present embodiment and secondary rolling thread groove 2 will the bad phenomenon of outlet high pressure lower than the words of 6mm, just need to carry out fly line processing, so by limiting the width of secondary rolling thread groove 2, make the safe distance between elementary winding slot 1 and secondary rolling thread groove 2 be not less than 6mm, avoided the bad defect of high pressure, in actual production process, remove this operation of fly line, improved production efficiency.
In the present embodiment, described secondary rolling thread groove 2 is also provided with wrapping post 22, the setting vertical with PIN pin 21 of described wrapping post 22, the enamelled wire that secondary rolling thread groove 2 is pulled out is first walked around wrapping post 22, on PIN pin 21, increase the insulation distance between elementary wire casing 1 and secondary wire casing 2 again, the insulation distance between elementary wire casing 1 and secondary wire casing 2 is too little, can cause the alternating current induction between elementary wire casing 1 and secondary wire casing 2 inaccurate, make transformer cisco unity malfunction.
In the present embodiment, described wrapping post 22 is one-body molded with secondary rolling thread groove 2, saves material, cost.
In the present embodiment, the width of described secondary rolling thread groove 2 is 8mm, and safe distance the shortest between elementary winding slot 1 and secondary rolling thread groove 2 is not less than 6mm, and according to the difference of transformer, the concrete numerical value of the width of secondary rolling thread groove 2 is also different.
In the present embodiment, described connector 3 is provided with magnetic core hole 31, in magnetic core hole 31, is provided with magnetic core, while being connected with alternating current in primary coil, just produces exchange flux in magnetic core, makes to induce in secondary coil voltage or electric current.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
