Description
【０００１】[0001]
本考案は、磁気ヘッドの取付構造に関する。 The present invention relates to a magnetic head mounting structure.
【０００２】[0002]
従来、ＶＴＲの音声用の磁気ヘッドの取付構造として、図４及び図５に示され ているものが知られている。 Conventionally, as a mounting structure of a magnetic head for voice of a VTR, those shown in FIGS. 4 and 5 are known.
【０００３】 図４は、磁気ヘッドの取付構造の正面図である。図５は、取付板の上面図であ る。磁気ヘッド１は、図示しないコア等を樹脂でモ−ルドしたものにシ−ルドケ −ス２を被着することにより構成されている。そしてこの磁気ヘッド１の前面３ は、曲面となった柱状に形成されている。次に、磁気ヘッドの取付構造について 説明する。まず、磁気ヘッド１の一端部である底面を取付板４に乗せる。その際 、取付板４に設けられている突部５を磁気ヘッド１の底面に当接させる。次に、 突部５の裏側から一方の電極６を取付板４に接触させ、また磁気ヘッド１の上面 に他方の電極７を接触させる。この状態で、電極６と電極７で磁気ヘッド１に対 し、加圧しながら電流を流す。これにより、突部５が加熱されて溶けることで、 磁気ヘッド１の底面と取付板４が溶接されている。なお、磁気ヘッド１の上面と 磁気ヘッド１の底面が逆になってもかまわない。FIG. 4 is a front view of a magnetic head mounting structure. FIG. 5 is a top view of the mounting plate. The magnetic head 1 is constructed by attaching a shield case 2 to a core (not shown) molded with resin. The front surface 3 of the magnetic head 1 is formed in a curved column shape. Next, the mounting structure of the magnetic head will be described. First, the bottom surface, which is one end of the magnetic head 1, is placed on the mounting plate 4. At that time, the protrusion 5 provided on the mounting plate 4 is brought into contact with the bottom surface of the magnetic head 1. Next, one electrode 6 is brought into contact with the mounting plate 4 from the back side of the protrusion 5, and the other electrode 7 is brought into contact with the upper surface of the magnetic head 1. In this state, an electric current is applied to the magnetic head 1 with the electrodes 6 and 7 while applying pressure. As a result, the protrusion 5 is heated and melted, so that the bottom surface of the magnetic head 1 and the mounting plate 4 are welded. The top surface of the magnetic head 1 and the bottom surface of the magnetic head 1 may be reversed.
【０００４】 また、図６（Ａ）及び図６（Ｂ）は、溶接前及び溶接後の磁気ヘッドの取付構 造の取付部分を示す拡大正面図である。溶接前は、取付板４の突部５を磁気ヘッ ド１の底面に当接させておく。そして磁気ヘッド１と取付板４が、突部５を加熱 することにより二次元的に溶着されている。Further, FIGS. 6A and 6B are enlarged front views showing a mounting portion of the mounting structure of the magnetic head before and after welding. Before welding, the projection 5 of the mounting plate 4 is brought into contact with the bottom surface of the magnetic head 1. The magnetic head 1 and the mounting plate 4 are two-dimensionally welded by heating the protrusion 5.
【０００５】[0005]
しかしながら、上記従来の磁気ヘッドの取付構造には次のような問題点があっ た。すなわち、取付板４に設けられている突部５は、取付板４における磁気ヘッ ド１の溶接面８の中央付近に設けられ、上述した方法により溶接されている。つ まり、磁気ヘッド１と取付板４が、突部５を加熱することにより二次元的に溶着 されている。また、各突部５を結ぶ距離が短い。このため磁気ヘッド１は側面方 向、前面方向、あるいは背面方向の外力に対する強度が小さい。つまり、磁気ヘ ッド１の側面方向から外力が加えられた場合、あるいは側面方向の成分を有する 外力が加えられた場合、磁気ヘッド１が傾斜し、アジマスを変化させてしまう。 また、磁気ヘッド１の前面方向又は背面方向から外力が加えられた場合、あるい は前面方向又は背面方向の成分を有する外力が加えられた場合、磁気ヘッド１の チルトが変化し、磁気テ−プ９が磁気ヘッド１のテ−プ摺接面１０に正しく摺接 しなくなる。 However, the above conventional magnetic head mounting structure has the following problems. That is, the protrusion 5 provided on the mounting plate 4 is provided near the center of the welding surface 8 of the magnetic head 1 on the mounting plate 4, and is welded by the method described above. That is, the magnetic head 1 and the mounting plate 4 are two-dimensionally welded by heating the protrusion 5. Further, the distance connecting the protrusions 5 is short. Therefore, the magnetic head 1 has a small strength against an external force in the side surface direction, the front surface direction, or the back surface direction. That is, when an external force is applied from the side surface direction of the magnetic head 1 or an external force having a component in the side surface direction is applied, the magnetic head 1 tilts and changes the azimuth. Further, when an external force is applied from the front direction or the back direction of the magnetic head 1 or when an external force having a component in the front direction or the back direction is applied, the tilt of the magnetic head 1 changes and the magnetic tape The tape 9 does not slide properly on the tape sliding surface 10 of the magnetic head 1.
【０００６】 本考案は、磁気ヘッドに何らかの外力が加えられてもアジマスやチルト等が変 化することを防止でき、安定した取付構造が得られる磁気ヘッドの取付構造を提 供することを目的とするものである。An object of the present invention is to provide a magnetic head mounting structure that can prevent a change in azimuth, tilt, etc. even when an external force is applied to the magnetic head, and that provides a stable mounting structure. It is a thing.

本考案の磁気ヘッドの取付構造は、磁気ヘッドを取付板に固定する磁気ヘッド の取付構造において、磁気ヘッドの端部の周縁部を抱え込む保持部を取付板に突 設したことを特徴としている。 The magnetic head mounting structure of the present invention is characterized in that, in the magnetic head mounting structure for fixing the magnetic head to the mounting plate, a holding portion for holding the peripheral edge portion of the end of the magnetic head is projected from the mounting plate.
【０００８】[0008]
本考案の磁気ヘッドの取付構造によれば、磁気ヘッドの端部の周縁部を抱え込 む保持部を取付板に突設することにより、磁気ヘッドの側面方向、前面方向、あ るいは背面方向の傾きを防ぐことができる。 According to the magnetic head mounting structure of the present invention, the holding portion that holds the peripheral edge of the end portion of the magnetic head is provided on the mounting plate so as to project from the side surface, the front surface, or the rear surface of the magnetic head. The inclination of can be prevented.
【０００９】[0009]
図１から図３までは、本考案の磁気ヘッドの取付構造の一実施例を示すもので ある。なお、従来例と同一の構成、部分については同一符号が付してある。 1 to 3 show an embodiment of a magnetic head mounting structure of the present invention. The same components and parts as those in the conventional example are designated by the same reference numerals.
【００１０】 図１は、本実施例の磁気ヘッドの取付構造の正面図である。図２は、本実施例 の取付板の上面図である。FIG. 1 is a front view of a magnetic head mounting structure of the present embodiment. FIG. 2 is a top view of the mounting plate of this embodiment.
【００１１】 磁気ヘッド１の一端部である底面の周縁部を抱え込む保持部１１が取付板４に 突設されている。この保持部１１は、取付板４に取り付けられる磁気ヘッド１の 四端部に設けられている。A holding portion 11 that holds the peripheral portion of the bottom surface, which is one end portion of the magnetic head 1, is projectingly provided on the mounting plate 4. The holding portions 11 are provided at the four ends of the magnetic head 1 attached to the attachment plate 4.
【００１２】 これら各保持部１１は、次のようにして形成される。磁気ヘッド１の底面を取 付板４に乗せ、取付板４に設けられているくさび形状の突部１２の斜面の部分に 磁気ヘッド１の底面の周縁部を当接させる。この時、磁気ヘッド１の底面と取付 板４における磁気ヘッド１の溶接面８が一致するように磁気ヘッド１の底面を取 付板４に乗せる。そして、突部１２の裏側から一方の電極６を取付板４に接触さ せ、また磁気ヘッド１の上面に他方の電極７を接触させる。この状態で、電極６ と電極７で磁気ヘッド１に対し、加圧しながら電流を流す。これにより、突部１ ２が加熱されて溶けることで保持部１１となり、この保持部１１を介して磁気ヘ ッド１の底面と取付板４が溶接される。なお、磁気ヘッド１の上面と磁気ヘッド １の底面が逆になってもかまわない。Each of these holding portions 11 is formed as follows. The bottom surface of the magnetic head 1 is placed on the mounting plate 4, and the peripheral portion of the bottom surface of the magnetic head 1 is brought into contact with the sloped portion of the wedge-shaped projection 12 provided on the mounting plate 4. At this time, the bottom surface of the magnetic head 1 is placed on the mounting plate 4 so that the bottom surface of the magnetic head 1 and the welding surface 8 of the magnetic head 1 on the mounting plate 4 coincide with each other. Then, one electrode 6 is brought into contact with the mounting plate 4 from the back side of the protrusion 12 and the other electrode 7 is brought into contact with the upper surface of the magnetic head 1. In this state, current is applied to the magnetic head 1 while applying pressure to the electrodes 6 and 7. As a result, the protrusion 12 is heated and melted to become the holding portion 11, and the bottom surface of the magnetic head 1 and the mounting plate 4 are welded via the holding portion 11. The top surface of the magnetic head 1 and the bottom surface of the magnetic head 1 may be reversed.
【００１３】 なお、本実施例において、保持部１１の形状については、磁気ヘッド１の端部 の周縁部に当接するような突起状のものであれば良く、保持部１１の数について は、設けられた保持部１１すべてが、磁気ヘッド１の端部の周縁部に当接するよ うな数であれば幾つでも良い。さらに、保持部１１の位置については、磁気ヘッ ド１の端部の周縁部に当接するような位置であれば良い。It should be noted that in the present embodiment, the shape of the holding portions 11 may be any projection shape that comes into contact with the peripheral portion of the end portion of the magnetic head 1, and the number of holding portions 11 may be different. Any number of holding parts 11 may be used as long as they are in contact with the peripheral portion of the end of the magnetic head 1. Further, the position of the holding portion 11 may be any position as long as it comes into contact with the peripheral portion of the end portion of the magnetic head 1.
【００１４】 また、図３（Ａ）及び図３（Ｂ）は、本実施例の溶接前及び溶接後の磁気ヘッ ドの取付構造の取付部分を示す拡大正面図である。溶接前は、取付板４の突部１ ２を磁気ヘッド１の底面の周縁部に当接させておく。そして磁気ヘッド１と取付 板４が、突部１２を加熱することにより三次元的に溶着される。3 (A) and 3 (B) are enlarged front views showing a mounting portion of the mounting structure of the magnetic head before and after welding according to the present embodiment. Before welding, the projection 12 of the mounting plate 4 is brought into contact with the peripheral edge of the bottom surface of the magnetic head 1. Then, the magnetic head 1 and the mounting plate 4 are three-dimensionally welded by heating the protrusion 12.
【００１５】 ここで、磁気ヘッド１と取付板４が、突部１２を加熱することにより三次元的 に溶着され、また各保持部１１を結ぶ距離が従来例よりも長くなることによって 、磁気ヘッド１は側面方向、前面方向、あるいは背面方向の外力に対する強度が 従来例より大きくなる。つまり、磁気ヘッド１の側面方向から外力が加えられた 場合、あるいは側面方向の成分を有する外力が加えられた場合の磁気ヘッド１が 傾斜するようなことはなく、アジマスの変化はなくなる。また、磁気ヘッド１の 前面方向又は背面方向から外力が加えられた場合、あるいは前面方向又は背面方 向の成分を有する外力が加えられた場合、磁気ヘッド１のチルトの変化もなくな る。Here, the magnetic head 1 and the mounting plate 4 are three-dimensionally welded by heating the protrusion 12, and the distance connecting the holding portions 11 is longer than in the conventional example, so that the magnetic head In No. 1, the strength against external force in the side surface direction, the front surface direction, or the back surface direction is greater than that of the conventional example. That is, the magnetic head 1 does not tilt when an external force is applied from the side surface direction of the magnetic head 1 or when an external force having a component in the side surface direction is applied, and the azimuth does not change. Further, when an external force is applied from the front direction or the back direction of the magnetic head 1 or an external force having a component in the front direction or the back direction is applied, the tilt of the magnetic head 1 does not change.
【００１６】 また、磁気ヘッド１の底面を取付板４に乗せた時、保持部１１は位置決めの役 目もする。Further, when the bottom surface of the magnetic head 1 is placed on the mounting plate 4, the holding portion 11 also serves as positioning.
【００１７】 さらに、上述した溶接方法によると、通電時に電流が磁気ヘッド１の上面部と 底面部の間で磁気ヘッド１の側面部分のシ−ルドケ−ス２を流れるため、磁気ヘ ッド１の前面３の発熱は、従来例より減少する。よって磁気ヘッド１のテ−プ摺 接面１０の歪みは減少し、ゆえに磁気ヘッド１のギャップ段差、コア・ガ−ド段 差、コア・ケ−ス段差等の不良を起こすようなことがほとんどなくなる。Further, according to the welding method described above, the current flows through the shield case 2 on the side surface portion of the magnetic head 1 between the top surface portion and the bottom surface portion of the magnetic head 1 during energization, so that the magnetic head 1 The heat generation on the front surface 3 of the above is reduced as compared with the conventional example. Therefore, the distortion of the tape sliding surface 10 of the magnetic head 1 is reduced, and therefore, the gap of the magnetic head 1, the difference between the core and the guard, the difference between the core and the case, and the like are mostly caused. Disappear.
【００１８】 ところで、磁気ヘッド１の端部の周縁部を抱え込む保持部１１、すなわち突部 １２を取付板４に突設することにより、レ−ザ−ビ−ムを突部１２に当てて溶着 する方法や、接着剤を突部１２付近に塗布することによる接着で、磁気ヘッド１ を取付板４に固定することが可能となる。このとき、上述した電極６、７を使用 した溶接による磁気ヘッド１の前面３の発熱はなくなり、磁気ヘッド１のテ−プ 摺接面１０の歪みはほとんどない。By the way, the holding portion 11 that holds the peripheral edge of the end of the magnetic head 1, that is, the protrusion 12 is provided on the mounting plate 4 so that the laser beam is applied to the protrusion 12 and welded. The magnetic head 1 can be fixed to the mounting plate 4 by the above method or by applying an adhesive near the protrusion 12. At this time, heat generation on the front surface 3 of the magnetic head 1 due to the welding using the electrodes 6 and 7 described above is eliminated, and the tape sliding contact surface 10 of the magnetic head 1 is hardly distorted.
【００１９】[0019]
以上説明したように、本考案によれば、磁気ヘッドの端部の周縁部を抱え込む 保持部を取付板に突設する。この時、磁気ヘッドは取付板上に三次元的に保持さ れる。また、保持部で囲まれる支持領域が従来例よりも広くなる。よって、磁気 ヘッドは側面方向、前面方向、あるいは背面方向の外力に対する強度がより大き くなるという効果がある。 As described above, according to the present invention, the holding portion that holds the peripheral portion of the end portion of the magnetic head is provided on the mounting plate in a protruding manner. At this time, the magnetic head is held three-dimensionally on the mounting plate. In addition, the support area surrounded by the holding portion becomes wider than in the conventional example. Therefore, the magnetic head has an effect that the strength against the external force in the side surface direction, the front surface direction, or the back surface direction becomes larger.
