  The electromagnetic valve 10 according to the embodiment of the present invention is basically configured as described above. Next, a case where the connector portion 24 is assembled to the solenoid portion 20 will be described. It is assumed that the valve body 18 and the solenoid unit 20 constituting the electromagnetic valve 10 are assembled in advance.

  First, the pair of connection terminals 102a and 102b to which the lead wire 100 having a desired length shown in FIG. 2 is connected are connected to the second insertion hole 104a of the connection portion 92 in the connector portion 24 from the other end side (arrow A direction). 104b and moved toward the connector main body 90 side (in the direction of arrow A), as shown in FIG. It is engaged and positioned at a predetermined position, and is fixed to the connector portion 24 in a state where movement in the longitudinal direction (arrow A, B direction) is restricted.

  At this time, as shown in FIG. 5, the connection terminals 102a and 102b are completely accommodated in the second insertion holes 104a and 104b, and the lead wire 100 extends outward from the other axial end of the connection portion 92. Present and exposed.

  Next, the connector part 24 to which the lead wire 100 including the connection terminals 102a and 102b is connected is arranged so that the connector main body 90 faces the other axial end of the solenoid part 20, and the other axial end of the casing 36 is arranged. Move closer to cover.

  As shown in FIGS. 3 and 4, the pair of connection pins 54a and 54b are inserted into the first insertion holes 98a and 98b of the connector portion 24, respectively, with respect to the other end portions of the connection terminals 102a and 102b.

A state in which the lead wire 100 connected to the connector unit 24 is connected in advance to a controller (not shown) will be described.

  First, the first switching state shown in FIG. 3 shows a non-excited state in which the coil 38 is not energized, and the movable core 44 is moved to the valve body 18 side by the elastic force of the first spring 64 ( The valve body 66 is displaced in the direction of arrow A) and one end in the axial direction of the valve body 66 is in contact with the cap 30, and the second port 14 and the third port 16 are in communication with each other.

  In the first switching state, the pressure fluid supplied from the pressure fluid supply source (not shown) to the third port 16 flows to the second port 14 side in the valve hole 26 through the second communication recess 86, and this second A fluid pressure device (not shown) is supplied through the port 14.

  Next, when the electromagnetic valve 10 in the first switching state is switched to the second switching state in which the first port 12 and the second port 14 communicate with each other, a control signal from a controller (not shown) is sent from the lead wire 100. It is supplied to the coil 38 of the solenoid unit 20 through the connection terminals 102a and 102b and the connection pins 54a and 54b. The coil 38 is excited by this energization, and the movable core 44 is attracted toward the fixed core 42 (in the direction of arrow B) by the excitation action, and the movable core 44 is against the elastic force of the first spring 64. It moves to the fixed core 42 side (arrow B direction).

  As the movable core 44 moves, the valve body 66 moves away from the cap 30 by the elastic force of the second spring 68, and the movable core 44 comes into contact with one end of the fixed core 42 in the axial direction. The movement of the body 66 in the axial direction stops. As a result, the valve portion 70 of the valve body 66 has the seal ring 82 on the other end side in the axial direction abutting against the valve seat 110 formed at the opening portion of the second port 14, and the second port 14 and the third port 16. At the same time, the second switching state in which the first port 12 and the second port 14 communicate with each other via the first communication recess 84 is established.

  In this second switching state, the pressure fluid supplied to the first port 12 from a pressure fluid supply source (not shown) flows to the second port 14 side in the valve hole 26 through the first communication recess 84, and this second port 14 is supplied to a fluid pressure device (not shown). Further, the pressure fluid remaining in the valve hole 26 is discharged to the outside through the third port 16.
