Description

Изобретение относитс к приборостроению , в частности в технике магнитной записи,, и может быть использовано при конструировании блоков магнитных головок.The invention relates to instrumentation, in particular in the technique of magnetic recording, and can be used in the design of blocks of magnetic heads.

Известен блок магнитных головок , состо щий из корпуса и сердечников , выполненных с сужени ми и имеющих обмотки с выводами. Обмотки выполнены с бескаркасными оболочка- ми l.A block of magnetic heads is known, consisting of a body and cores made with constrictions and having windings with leads. The windings are made with frameless shells l.

Надежность работы такой головки невысока из-за недостаточно прочной фиксации сердечника с обмоткой в корпусе, тай как размеры установочных плоскостей ограничены.The reliability of such a head is low due to insufficiently strong fixing of the core with the winding in the housing, and how the dimensions of the installation planes are limited.

Известен также блок магнитных головок, содержащий расположенные между экранами по.пюсные наконечники, соединённые между собой в монолит, и сер;1ечники q обмотками в бескаркасных оболочках. Достоинством такой конструкции вл етс исключение необходимости изготовлени каркасных катушек головок 2.A block of magnetic heads is also known, containing pin-to-tip ferrules interposed between screens, interconnected in a monolith, and sulfur; 1-point tips q windings in frameless shells. The advantage of this design is the elimination of the need to manufacture the frame coils of the heads 2.

Однако минимизаци сердечника св зана с трудност ми его фиксации в кйрпусе из-за ограниченных размеров его установочных плоскостей, в результате чего надежность работы блока невысока из-за его невысокой жесткости . - - However, minimization of the core is associated with the difficulties of its fixation in the core due to the limited dimensions of its installation planes, as a result of which the reliability of the unit is low due to its low rigidity. - -

Целью изобретени вл етс повышение надежности работы блока за счет увеличени его жесткости.The aim of the invention is to increase the reliability of the unit by increasing its rigidity.

Поставленна цель достигаетс тем, что в блоке магнитных головок, содержащем корпус, в котором размещены сердечники с обмотками в бес10 каркасных оболочках, и монолитную полюсную часть, приклеенную к корпусу с помощью клеевых прослоек, бескаркасные оболочки выполнены с шириной, равной ширине, и высотой, равной The goal is achieved by the fact that in a block of magnetic heads comprising a case in which cores with windings in frameless shells are placed, and a monolithic pole part glued to the case with adhesive layers, frameless shells are made with a width equal to the width and height equal to

15 толщине сердечников, так, что внешние стороны сердечников образуют с бескаркасными оболочками единые установочные плоскости, по которым бескаркасные оболочки и сердечники 15 thickness of the cores, so that the outer sides of the cores form with frameless shells a single installation plane, along which frameless shells and cores

20 жестко закреплены в корпусе, при этом бескаркасные оболочки выполнены из материала с жёсткостью, большей жесткости материала клеевых про: слоек.20 are rigidly fixed in the case, while frameless shells are made of a material with rigidity, greater rigidity of the material of adhesive: puffs.

Claims

30 shell; FIG. 4 - core U-shaped fbrmy / n fir. 5 - U-shaped core with a winding in a frameless sheath; in fig. (b) core with cores fixed in it with windings in frameless shells; in fig. 7 - block of magnetic heads: The block of magnetic heads contains pole tips 2 located between the screens 1, which are interconnected in a monolithic pole Hi a part of the block with glass bonding material h. The working gap in the pole pieces is formed by a glass gasket 4. The cores 5 with windings are placed inside frameless shells 7 and fixed in the case 8 by means of adhesive layers 9. The cores 5 can be either Y-shaped or U-shaped and have bored parts 10, on which windings b are located, which have external leads 11. Frameless shells 7 can be made of compound yes. The width of frameless shells 1. is equal to the core diameter of the core It, while the lateral surfaces 12 of the shells 7 and the outer sides of the 13 cores 5 form: uniform installation planes A. The cores with the shells are uniform. assemblies, which, after applying the adhesive material, side planes A are rigidly fixed along these planes in the housing 8, having a through hole. 14, L grooves 15 under the inter-head screens 1. External leads 11 of the windings 6 are brought out through hole 14 and spread on pins 16 of the head 17. Hole cavities 14 are filled with compound 18. Monolithic pole part is connected with the cores along contact planes 19 In the proposed magnetic head assembly, cores with frameless winding shells constitute unified assembly structural elements. Frameless shell with a limited size of cores you-. play the role of a structural element that ensures precise installation and reliable fastening of the cores in the block body, as a result of which the rigidity of the structure increases. High rigidity of the head design allows to significantly increase the reliability of its operation. Claims of Invention: A magnetic head assembly comprising a housing in which cores with windings in frameless shells are placed, and a monolithic pole portion attached to the housing with adhesive layers, characterized in that, in order to increase the reliability of operation of the block by increasing its Gestures, frameless shells are made with a width equal to the width and a height equal to the thickness of the cores so that the outer sides of the cores form with the frameless shells uniform mounting planes along which the frameless span of cores and are rigidly fixed in the housing, wherein the frameless le shell performed. They are made of a material with rigidity, greater rigidity of the material of adhesive interlayers. Sources of information accepted. Attention in the examination 1.
