lug

14,15 two lateral margins then convex with

fin

16,17, and with the tenon 12 and the caulking groove 13 of these lamellar body 11 joint portions, mutually the embedding clinching is merged group and is a tubular shell 10, by this with the waste that reduces material and obtain higher quality.

This bottom 20 is provided with a perforation 21 in central authorities, and cover is consolidated a fixed iron core 22 in perforation 21, then establish in the top end face of fixed iron core 22 and to be the Dou face 23 that inclines, increasing the magnetic force contact area with movable core 50, and be equipped with the groove 24 of corresponding above-mentioned lamellar body 11 bottom lugs 15 in bottom 20 lateral margins.

This loam cake 30 is provided with a thread head 31 in outboard end, and is provided with a through hole 32 in central authorities, can supply movable core 50 head ends pass, and also is equipped with the groove 33 of corresponding lamellar body 11 top ends lugs 16 in loam cake 30 lateral margins.

When assembling, the lug 15 that the groove 24 of lower cover 20 is aimed at housing 10 bottoms covers, and in bottom 20 it is fixed fin 17 rivetings of lug 15 2 sides, to reach the convenience that is easy to assemble; And are device one bobbins 40 in housing 10 inside, these bobbin 40 2 ends are to have a base plate 41 respectively, and 41 of this two base plates are to be arranged with a coil 42, and has an intercommunicating pore 43 in the centre of these bobbin 40 1 end faces, and be this movable core 50 of configuration in this intercommunicating pore 43, these movable core 50 bottoms then establish be one with the Dou face 23 corresponding conical end 51 of inclining of fixed iron core 22, the top then is provided with one can be made for the profile groove 52 that moving part connects, and be provided with one vertical and run through profile groove 52 fixing holes 53 in lateral margin, fixing hole 53 belows then are provided with an annular groove 54, again loam cake 30 is placed in movable core 50, the leading section of movable core 50 is exposed outside, and the lug 14 that the groove 33 of loam cake 30 peripheries is aimed at housing 10 tops covers, and in loam cake 30 it is fixed fin 16 rivetings of lug 14 2 sides, and a nut 34 spiral shells are located at the thread head 31 of loam cake 30, the sheathed pad 55 in movable core 50 ends again, and on its annular groove 54, fasten a C type ring 56, by this to constitute the structure of magnetic yoke of an electromagnet.
