【００２２】 而してリニアソレノイドＬＳを組立てる際には、図６で示すように、一対の端 子組立体２５を埋設した端板１２を予め準備しておき、ヨーク７、固定コア８、 第１鍔部９、第２鍔部１０、カバー１１、ボビン２０に巻装したコイル４を仮に 組付けておく。而して第１鍔部９から突出した一対の突部２３が、孔３３にそれ ぞれ嵌入されるようにして端板１２を第１鍔部９の外面に当接させ、カバー１１ の一端の薄肉円筒部１１ａを端板１２にかしめて結合する。そうするとコイル４ の端部４ａ，４ｂが両端子組立体２５の第１端子２７における両半割り円筒部２ ７ｄ，２７ｄ間に挿入されることになり、両半割り円筒部２７ｄ，２７ｄで前記 端部４ａ，４ｂを挟むようにして電気抵抗溶接を施すことにより、端部４ａ，４ ｂが、両端子組立体２５の第１端子２７にそれぞれ接続されることになる。次い で第２端子２８に外部リード線２４ａ，２４ｂをナット３８でそれぞれ接続する ようにすればよい。[0022] Therefore, when assembling the linear solenoid LS, as shown in Figure 6, The end plate 12 in which the child assembly 25 is buried is prepared in advance, and the yoke 7, fixed core 8, The coil 4 wound around the first flange 9, the second flange 10, the cover 11, and the bobbin 20 is temporarily Assemble it. Thus, the pair of protrusions 23 protruding from the first flange 9 are inserted into the holes 33. The end plate 12 is brought into contact with the outer surface of the first flange 9 so as to be fitted into each other, and the cover 11 The thin cylindrical portion 11a at one end is caulked and connected to the end plate 12. Then coil 4 The ends 4a and 4b of the two half-split cylindrical portions 2 of the first terminal 27 of the both terminal assemblies 25 It will be inserted between 7d and 27d, and the above-mentioned By performing electric resistance welding so as to sandwich the ends 4a and 4b, the ends 4a and 4 b will be connected to the first terminals 27 of both terminal assemblies 25, respectively. next Connect the external lead wires 24a and 24b to the second terminal 28 with nuts 38, respectively. Just do it like this.
【００２３】 このようなリニアソレノイドＬＳにおいて、ボビン２０は、コイル４の端部４ ａ，４ｂを引き出すための一対の突部２３を有するだけの比較的単純な構造であ ればよく、コイル４の端部４ａ，４ｂは、端板１２の外面側で第１端子２７にそ れぞれ接続されるものであり、接続作業が容易となるだけでなく、接続部を外部 から視認可能であるので組立後の管理が容易である。[0023] In such a linear solenoid LS, the bobbin 20 is connected to the end 4 of the coil 4. It has a relatively simple structure with only a pair of protrusions 23 for pulling out parts a and 4b. The ends 4a and 4b of the coil 4 may be connected to the first terminal 27 on the outer surface side of the end plate 12. This not only simplifies the connection work, but also allows the connection to be connected externally. Since it is visible from the outside, management after assembly is easy.
【００２４】 また外部リード線２４ａ，２４ｂは、ねじ軸部２８ｃへのナット３７の螺合、 締付けにより第２端子２８に接続されるので、接続強度を大として、信頼性を向 上することができる。[0024] Further, the external lead wires 24a and 24b are connected to the screw shaft portion 28c of the nut 37, Since it is connected to the second terminal 28 by tightening, the connection strength is increased and reliability is improved. can be raised.
