Background

At present, with the mass appearance and use of electronic equipment, transformers in power supply devices are also widely used in a large quantity, and the high voltage is converted into 220V working voltage. Chinese patent No. 201620934590.X discloses an improved transformer, utilize the housing to be connected with the magnetic core among its technical scheme, can effectively improve withstand voltage level, the condition that the electronic components of significantly reducing were punctured, nevertheless because the housing is four sides half-packet structure, can't be to the whole parcel of magnetic core one side, partly still probably be close to with peripheral electronic components and cause the breakdown phenomenon to expose, just so need guarantee that electronic components and transformer keep 3 mm's safe distance, be unfavorable for mainboard space design, can't further make mainboard space compact.

SUMMERY OF THE UTILITY MODEL

The utility model discloses solve the problem that above-mentioned prior art exists, provide a novel transformer, solve present power transformer and save the problem of structure space difficulty.

The utility model provides a technical scheme that its technical problem adopted: the novel transformer comprises a framework, wherein pins are arranged on the framework, coils are wound on the framework, two ends of each coil are connected with the pins respectively, a magnetic core which penetrates through the center of each coil and surrounds the outer ring of each coil is fixed on the framework, a protective cover is connected to the side face, corresponding to the low-voltage pins, of each magnetic core, an embedded groove is formed in one face, corresponding to the magnetic core, of each protective cover, the embedded groove is tightly attached to the inner wall of each magnetic core to form a wrapped structure, a gap is reserved between the framework and the magnetic core, and the upper end and the lower end of each protective cover are inserted into the gap. After setting up like this, the protection casing insertion gap is fixed, high durability and convenient installation, the protection casing is from the top, down, a left side, right side and front side parcel magnetic core one side, the parcel effect of half the package of comparing is better, it has the restriction to consider on the mainboard electric capacity etc. and transformer distance, generally be 3mm, and the distance of reducing and outside electric capacity lamp components and parts that there is the protection casing parcel can be very big, can let electronic components directly paste on the protection casing even, make whole mainboard compacter, reduce mainboard specification size, greatly save material cost, also be convenient for design planning mainboard structure, the protection casing increases creepage distance by a wide margin, make withstand voltage reach 5000 additionally 5500V, be difficult to the breakdown condition, excellent in use effect.

As the utility model discloses a further improvement, the lower extreme is equipped with the recess that holds coil place skeleton on the protection casing, and the protection casing left and right ends extend backward along the magnetic core and cross partial coil and cladding in the magnetic core side from 1/3 backward to 1/2 interval in the past. After the protection casing inserted, the coil place skeleton was avoided to the recess for the right-hand member can also continue to impel backward until being located the magnetic core side from 1/3 backward to 1/2 interval, and the more magnetic core surfaces of protection casing parcel further increase the creepage distance of magnetic core to pin, increase and be close to the magnetic core region, then improve voltage resistance and compactedness comprehensively.

As a further improvement, the lower extreme is equipped with the bulge of fixing on the skeleton along the magnetic core orbit continuous setting on the clearance, and the terminal surface is equipped with about the protection casing and inserts and bulge joint complex joint portion. Utilize protruding portion card and the spacing connection of joint portion, assurance connection effect that also can be fine when not using glue to consolidate to connect reduces the process that adds glue, improves assembly efficiency.

As a further improvement of the utility model, the cross section of the protruding part and the joint part is of a semicircular structure, and the joint part passes through the protruding part and blocks the protruding part when being inserted. The protruding portion and the clamping portion of the semicircular structure effectively reduce the contact area when in contact, the contact moving resistance is better, the clamping is smoother and natural, and the clamping is convenient to mount and dismount.

As a further improvement of the utility model, the joint part is composed of a set of parallel raised parts and evenly spaced distributed raised ends. The joint portion is constituteed to interval distribution's bellying and with the spacing cooperation of jut, utilizes the spacing whole banding cooperation of formation of some, guarantees spacing joint effect when reducing material cost, because the point contact is connected, the installation is dismantled portably for a short time to the resistance moreover.

As a further improvement of the utility model, the joint portion comprises the protruding end of a set of crisscross distribution in the jut both sides, and the jut is held from the front and back side respectively to the protruding end. The protruding end is staggered to carry out the centre gripping spacing to it from protruding portion front and back both sides, and spacing effect is better, because the point contact is connected, the installation of resistance is little moreover and is dismantled portably.

As a further improvement, the protective cover is made of insulating material and is integrally made into a structure. After setting up like this, the protection casing furthest plays insulating effect, and insulating material self has certain degree elasticity moreover, better adaptation during the installation.

As a further improvement of the utility model, the creepage distance between the magnetic core and the output end is 6 mm. Creepage distance is 6mm and accords with the safety regulation requirement, satisfies the security, avoids the components and parts to be punctured the condition.

The utility model discloses profitable effect is: the utility model discloses a rational in infrastructure, compact wraps up the magnetic core simultaneously completely through the protection casing, and very big reducing makes things convenient for the mainboard planning design with the distance of outside electric capacity lamp components and parts, and the structure is compacter, save material cost, and the protruding portion card cooperates with joint portion, and simple to operate is swift, accords with ann's rule, greatly improves withstand voltage numerical value.
