Illustrated in figures 1 and 2ly be therapeutic apparatus of magnetic field generator according to an embodiment of the invention, wherein magnetic field generator 2 is placed in many shell 1 the insides that made by synthetic resin respectively.Shell 1 is connected into a row rotationally, and energy interconnective belt 12A, 12B are provided at the opposite end of shell 1A, shell 1B respectively.

Each shell 1 is to form like this, and is promptly right by the opening surface that makes two and half shells 10,11, can fix them in some places with screw.On a side end surface of each shell 1, as shown in Figures 2 and 3, outstanding vertically axle 13,13 is arranged, and corresponding on the opposite side end surfaces have a receiving orifice 14,14 at this place, thereby each outstanding axle 13 corresponding receiving orifice 14 of engagement between adjacent shell 1,1, shell 1,1 just is connected, and the linkage 15 that connects shell has rotationally just formed.

In linkage 15, guide hole 16,16 passes each guide hole 16 by changeing the inside of the heart to shell 1, is electrically connected and shell 1,1 magnetic field adjacent generator 2,2 with lead-in wire 34.

Because the opening surface by making two and half shells 10,11 is to forming shell 1, their outstanding axle 13 and receiving orifice 14 also are in released state along the axis.When two tools, half shell 10,11 is connected on a time-out, in the appropriate location of the contact surface of half shell 10,11, jog 17,18 just is meshing with each other.

Fig. 6 is to the structure that Figure 8 shows that this magnetic field generator 2.

This magnetic field generator is designed to by providing alternating current to produce an alternating magnetic field for coil 33, and coil 33 is on laminated core 20.As shown in Figure 4 and Figure 5, laminated core 20 is such structures, i.e. suitably the many stalloy 21A of lamination, 21B, and be wrapped with heat-stable insulating tape 26.Iron core 20 shown in the figure has projection 24a, 24b with the concentration magnetic flux, and this iron core is by stacking a pair of lamination 25A, 25B to form.Compare by the iron core that the calking stalloy constitutes with those, the iron core that assembles provides stronger oscillation action.

There are two pillar 23a, 23b in two ends in the bottom 22 of the iron core 20 that installs, bobbin 30a, 30b respectively with two pillars engagements.Among bobbin 30a, the 30b each is by forming along the bobbin 32 kinking coils 33 that have bead 31 at two ends.In the pillar 23a of laminated core 20, the endface position of 23b, be reprocessed into a cavity S0 in the inside of bobbin 30a, 30b, extremely shown in Figure 8 as Fig. 6.Cavity S0 is used for strengthening themogenesis and improves thermal effect in magnetic field generator 2.

Magnetic field generator 2 with aforementioned structure, is supported on above the projection 42 to shown in Figure 9 as Fig. 3, and this projection is at the inner surface of half shell back.Thereby, between half shell 11 and magnetic field generator 2, form air layer S1, suitably to limit the heat transferred shell 1 that produces by magnetic field generator 2.
