DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coil device suitable for detecting the rotational speed of a distribution type fuel injection pump or the like.

[0002]

2. Description of the Related Art As a coil device for detecting the number of revolutions of a distribution type fuel injection pump or the like, generally, a pole piece, a bobbin accommodating a magnet, a wire wound around the bobbin (coil wire), and a starting point of the wire And a second terminal connected to the end point of the wire.

In particular, the first and second terminals are mounted on a terminal mounting portion formed at one end of the bobbin from the outside (front side) thereof, and are connected to a starting point or an end point of a wire wound around the bobbin. And is connected to external terminals by soldering.

On the other hand, when a wire is wrapped around the first and second terminals, tension is generated in a portion of the wire located between the wire and the wire wound around the bobbin. The wire where the tension is generated is often broken.
The technology disclosed in Japanese Patent Laid-Open Publication No. H10-260, is known. This is characterized in that a terminal to be press-fitted into a press-fitting hole formed in a bobbin is formed in a rod shape, and a member disposed around the terminal is formed with a recessed portion that is depressed in the terminal press-fitting direction.

[0005] A rod-shaped terminal is inserted into the press-fitting hole, and the start or end of the wire wound around the bobbin is wrapped around the terminal. Then, the tip of the terminal is pressed to re-press the terminal into the press-fitting hole. . There is a recessed portion so that the portion of the rod-shaped terminal where the wire is entangled by this press-fitting does not get caught in the press-fitting hole, and the movement of the terminal at this time releases the tension of the wire.

On the other hand, the tip portion of the terminal is often formed in a quadrangular shape in cross section. In this case, when the wire is twisted, the four corners are rounded so that the wire is not broken at the four corners. Has formed. By doing so, it is possible to increase the tension acting on the wire when the wire is twisted and to strongly twist the wire.

[0007]

In the conventional coil device, the first and second terminals are mounted on a terminal mounting portion formed on one end of the bobbin from the outside (front side) to the back side. After being attached, the wire wound around the bobbin is tied to the start point or the end point, and
Is connected to the tip of the external terminal by soldering, when the external terminal is pulled outward, the first and second terminals are pulled out to the outside, There were problems such as the wire breaking.

[0008] Further, in the apparatus disclosed in Japanese Patent Application Laid-Open No. 5-159922, only a frictional force acts between the press-fitting hole and the rod-shaped terminal. Since there is no portion to be applied, there is a possibility that the terminal may be pressed too deeply into the press-fitting hole due to the adjustment of the force. In such a case, if the wire (coil wire) is pulled downward more than necessary and tension is generated again, there is a risk of disconnection. Conversely, when pulling out the terminal and returning it to the original position, the force may be adjusted. If you return it too much, there is a risk of disconnection.

The present invention has been made in view of the above-mentioned problems, and can prevent the first and second terminals from coming off even when a force acts on the first and second terminals or the external terminal.

The housing 57 is filled with, for example, an epoxy resin 60 to seal the entire bobbin 11 and take measures against moisture and the like. At this time, a part of the external terminal 55 is exposed to the outside.

In this embodiment, the first and second terminals 43, 43 are mounted from the back side of the terminal mounting portion 23. For example, during the manufacturing process, the external terminals 55 are pulled outward. The first and second terminals 43, 43 do not come off even if they are removed. Further, since the first and second terminals 43, 43 are provided with projections 47, 49 provided with a plurality of projections on the outer periphery, the first and second terminals 43, 43 are provided with a plurality of projections. Even if a pressing force is applied to the external terminal 55 after connection, the external terminal 55 does not come off to the back side of the terminal mounting portion 23. Therefore, even in such a case, the wire is not broken, which leads to a reduction in defects as a whole.

The connection between the terminal 43 and the external terminal 55 may be made by forming a male screw or a female screw on both of them instead of soldering. In order to simplify the configuration, it is desirable to form a female screw on the terminal 43 side and a male screw on the external terminal 55 side. In this case, connection and separation between the terminal 43 and the external terminal 55 are easy.

On the other hand, the first and second terminals 43, 43 are made of, for example, brass, and as shown in FIG.

it can. That is, the terminal tip portion 45 is moved downward in FIG.
, The connecting portion 61b is plastically deformed downward,
As a result, as shown in FIG.
Moves in the direction of the terminal mounting portion 23. In the case of such a configuration, as described above, the first and second terminals 4
3 and 43 are mounted on the terminal mounting portion 23 from the back side of the terminal mounting portion 23, and the first and second terminals 43 and 43 are mounted.
After the process of winding the start point side or the end point side of the wire wound around the bobbin 11 with respect to the terminal end portion 45 of the terminal is completed, as shown in the schematic view of the bobbin 11 shown in FIG. Of the terminal 43 of the terminal 43 is pressed downward in the drawing to connect the frame 61 described above.
When the portion 61b is plastically deformed , the terminal tip portion 4
The tension of the wire 63 (see FIG. 8) of the portion of the wire that is not subjected to the lashing and that leads to the wire wound around the bobbin 11 can be released.
When the tension of the wire 63 (see FIG. 8) is released in this manner, the risk of disconnection, which is likely to occur in the portion of the wire 63, can be effectively avoided.

Since the entire first and second terminals 43, 43 are made of brass, the connecting portions 6
When plastically deforming 1b, it is possible to perform plastic deformation at a uniform speed with a uniform pressing force to a certain extent, so that fine adjustment of plastic deformation is easy and excessive plastic deformation is caused. There is no. In addition, plastic deformation requires a large pressing force due to the tension applied to the material when the deformation becomes larger than a certain degree.
There is no plastic deformation. Therefore excessive
There is no possibility that the wire 63 is cut off due to plastic deformation. Further, since the frame 61 is made of brass, it does not return to its original state after being once plastically deformed, and furthermore, there is no crack or the like, and the quality reliability of the product is high.

FIG. 10 is a perspective view showing the structure of the terminal end portion of the terminal. The terminal tip portion 71 shown in the figure is the terminal tip portion 45 of the first and second terminals 43 and 43 described above.
It may be considered that it is applied to. In any case,
The terminal tip portion 71 shown in the figure has a tip portion (for example, a half portion from the tip to the root) formed in a conventional rectangular shape in cross section, and each corner has a radius of about 0.1 m.
A roundness from m to 0.15 mm is configured. And
A portion from a middle position to a root position of the terminal tip portion 71 is formed in a substantially elliptical shape in cross section, and the curvature of the curved surface is, for example, a radius of about 0.3 mm or more.

When the wire 73 is wrapped around the terminal tip portion 71, the wire 73 is gradually moved from the root side of the portion having a substantially elliptical cross section to the position of the tip. Then, when reaching the position closest to the position of the tip in the portion 75 having a rectangular shape in cross section, the wire 73 is strongly pulled at the corner and cut. Since the corner portion has a radius of about 0.1 mm, it can be easily cut. Thus, when the tying of the wire 73 is completed, the whole portion 75 having a square shape in cross section after the tying, that is, a solder dip is performed from the tip to the portion 77 having a substantially elliptical shape in cross section, and the tying of the wire 73 is fixed. .

When the terminal tip portion 71 having the above-described configuration is used, the mechanical stress is reduced due to the large roundness in the substantially elliptical portion 77 when viewed from the cross section, and the wire 73
The risk of disconnection is greatly reduced.
Then, it can be easily cut intentionally. Therefore, the workability of the lashes is improved, and the assemblability of the entire apparatus is improved.

Further, the terminal end portion 71 having the above-described structure can be manufactured by pressing, so that the cost does not increase. Therefore, the manufacturing cost of the terminal is the same as that of the conventional product.
