本考案は、コスト低減を図つたVTR（ビデオテ
ープレコーダ）用磁気ヘツドに関するものであ
る。[Detailed Description of the Invention] The present invention relates to a magnetic head for a VTR (video tape recorder) which is designed to reduce costs.
VTR用磁気ヘツド、例えば、オーデイオヘツ

するようにしている。 In a VTR magnetic head, for example, an audio control head in which an audio head and a control head are assembled in the same case, the head assembly is inserted into a metal case with the rear open, and the head assembly is inserted backwards. Insert the back plate from the rear of the case to the specified position inside the case so that the protruding terminal pin passes through the back plate, and
A resin is filled into the case behind the inserted back plate to seal it and to fix the lead-out terminal pin.
ところで、従来は、引出端子ピンの貫通する孔
が予めあけられている裏板を用意していたので、
コスト高になつていた。 By the way, conventionally, a back plate was prepared with holes drilled in advance for the extraction terminal pins to pass through.
Costs were getting high.
そこで本考案は、引出端子ピンの先端を鋭角に
し、その端子ピンで孔なしのフイルム状裏板を突
き通すようにしたVTR用磁気ヘツドを提供する
ものである。以下、図面を用いて実施例を説明す
る。 Therefore, the present invention provides a magnetic head for a VTR in which the tip of the lead-out terminal pin is made at an acute angle so that the terminal pin can penetrate a film-like back plate without holes. Examples will be described below with reference to the drawings.

内に樹脂７を充填する。 FIG. 1 shows an embodiment of the present invention.
1 is a metal case with an open rear end, 2 is a core having a gap 2a, into which a coil 3 is inserted.
Reference numeral 4 denotes a terminal fixing portion that is integrally provided on one brim of the bobbin of the coil 3, and a lead-out terminal pin 5 is implanted therein. The feature of the present invention is that the tip of the lead-out terminal pin 5 is formed at an acute angle. After the head assembly assembled in this way is inserted from the rear of the case 1 and fixed, and the front part is ground, a film-like back plate 6 (made of foamed polyethylene, etc.) without holes is attached using terminal pins 5. It is broken through and inserted into the case 1 to a predetermined position, and the resin 7 is filled into the case behind the back plate 6.
引出端子ピン５の先端形状は、第２図または第
３図に示したように形成し、フイルム状裏板を容
易に突き通せるようにする。 The tip of the pull-out terminal pin 5 is shaped as shown in FIG. 2 or 3 so that it can easily penetrate the film-like back plate.
本考案は、以上のように構成されているから、
予め穿孔した裏板を製作する必要はなく、それだ
けコスト低減を図ることができる利点がある。 Since the present invention is configured as described above,
There is no need to manufacture a back plate with holes drilled in advance, which has the advantage of reducing costs accordingly.
