It is provided with for energising terminal 15a~15c to be pressed into fixed insertion hole 13a~13c.In illustrated example, for example, it is rectangular-shaped
Three supporting fixed part 12a~12c are transversely arranged along the outer rim of terminal connection part 11 and formed, and in each supporting fixed part
The substantial middle of 12a~12c is provided with the circular insertion hole 13a~13c of such as section.
In each insertion hole 13a~13c of the terminal connection part 11 (each supporting fixed part 12a~12c), it is pressed into and props up
Energising terminal 15a~the 15c for being fixed with section rectangle is held, also, the root portion of each energising terminal 15a~15c is (solid from each bearing
Determine the range of the specific length after portion 12a~12c is protruded) corner formed fillet (it is special, with reference to the fillet part in Fig. 2,3
18a), it is provided with as a result, by the corner recess of energising terminal 15a~15c and shape in the root portion of each energising terminal 15a~15c
At sunk area 16a~16c.
In addition, in this example, by making the corner of each energising terminal 15a~15c (root portion) be formed as fillet
Sunk area 16a~the 16c, but for example as shown in Figure 4, can also by the corner to each energising terminal 15a~15c into
Row chamfering (chamfered section 19a) and form sunk area 16a~16c in each energising terminal 15a~15c.
As previously mentioned, the corner of each energising terminal 15a~15c is formed as fillet or chamfering, to the sunk area 16a
The section shape of~16c becomes five that rectangle (with reference to Fig. 3), round, ellipse or apex angle of such as corner with circular arc are more than 90 °
Polygon more than side shape (with reference to Fig. 4).
In addition, energising terminal 15a~15c with sunk area 16a~16c above-mentioned can be for example, by following manner
It makes：The wire rod (also referred to as linea angulata) for the section rectangle for constituting energising terminal 15a~15c is laid out from the state for being wound in reel
Specific length, and with the comparable length of energising terminal 15a~15c at cut off, meanwhile, make with each energising terminal 15a~15c's
(corner) compressive deformation of the comparable part of root portion and form the sunk area 16a~16c.
Magnet-wire 20 assigns defined drawing force on one side, and on one side around being attached to around bobbin 10, one end of magnet-wire 20 (is kept
Slightly loosely) winding (winding) in the sunk area 16a for being set to the root portion of energising terminal 15a or is set to energization for several times
The sunk area 16c of the root portion of terminal 15c, and in the position of the root portion far from energising terminal (that is, compared with sunk area
Positioned at the position of tip side) it is wound in energising terminal 15a or energising terminal 15c for several times once again, and utilizing section rectangle
The corner of energising terminal and defined position be cut off after, by be coated on the sunk area 16a compared be located at push up
The solder 17a of the part of end side is coated on electric positioned at the solder 17c of the part of tip side compared with the sunk area 16c
It is fixed on energising terminal 15a or energising terminal 15c to connection (conducting).In addition, the other end of magnet-wire 20 (keeps slightly relaxing
Ground) it is wrapped in the sunk area 16b for the root portion for being set to central energising terminal 15b for several times, and far from energising terminal 15b
Root portion position (that is, compared with sunk area 16b be located at tip side position) be wound in energising terminal for several times once again
15b, and in the corner of the energising terminal 15b of utilization section rectangle and after defined position is cut off, by being coated on
Compared with the sunk area 16b energising terminal is fixed on positioned at the solder 17b of the part of tip side with being electrically connected (conducting)
15b。
Also, to cover the peripheral part of the magnet-wire 20 in above-mentioned coil device 1, the terminal connection part 11 of bobbin 10, consolidate
It is formed with moulded resin (not shown) due to the mode in the outside of energising terminal 15a~15c of the terminal connection part 11 etc..
Coil device 1 with structure as described above can be used in motor-driven valve (such as refrigeration cycle, heat-pump-type system
Motor-driven valve used in cold heating system etc.), (such as the fluid system of refrigeration cycle, multi-type air conditioning system etc. is made solenoid valve
Solenoid valve) etc., which has the stepper motor for the stator coil being made of the coil device 1, the valve with valve port
Main body and valve shaft of the drive force to which the valve port be opened and closed caused by being powered to the stepper motor, should
Solenoid valve has the solenoid coil being made of the coil device 1, the valve body with valve port and to the stepper motor
Valve shaft of the magnetic drive caused by being powered to which the valve port be opened and closed is (about detailed construction, with reference to above-mentioned patent text
Offer 1,2 etc.).
In this way, in the coil device 1 of present embodiment, it is logical what is be provided projectingly from the terminal connection part 11 of bobbin 10
The root portion of electric terminal 15a~15c is provided with sunk area 16a~16c, sunk area 16a~16c for temporarily wind from
The magnet-wire 20 that bobbin 10 is laid out, therefore sunk area 16a~16c becomes winding zone (region that should wind magnet-wire)
Target easily can be wound in energising terminal 15a~15c with eyes observation etc. by (such as in manufacturing process) to confirm
Magnet-wire 20 winding state (defect state etc. of winding), therefore, it is possible to make to be wound in the magnet-wire of energising terminal 15a~15c
20 winding is in stable condition.In addition, even if by magnet-wire 20 keep slightly relaxation (more than needed) be wound into energising terminal 15a~
In the case of 15c, the magnet-wire 20 for being wound in sunk area 16a~16c be difficult to be detached from from sunk area 16a~16c and can
The winding width of magnet-wire 20 is controlled and (in other words, winding width is kept as uniformly) within Rack, therefore, passes through this
A bit, it can also make the winding for being wound in energising terminal 15a~15c magnet-wire 20 in stable condition.
In addition, in the above-described embodiment, being located at top compared with sunk area 16a in energising terminal 15a~15c
The position of side is coated with solder 17a~17c and magnet-wire 20 is fixed on energising terminal 15a~15c, but in order to mitigate be formed in it is logical
Magnet-wire is born caused by the step on (boundary) between sunk area and general portion (part of section rectangle) in electric terminal
Lotus, can also for example as shown in Figure 5, by for fixing the solder 17a of energising terminal 15a by sunk area 16a
End (that is, including the part for the step being formed between sunk area 16a and general portion) and be wound in the sunk area
The end of the magnet-wire 20 of 16a covers.
In addition, in the above-described embodiment, the sunk area for temporarily winding magnet-wire is set to the root of energising terminal
Point, it will be clear that the setting position of the sunk area is not limited to the root portion of energising terminal.
