Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an electromagnetic solenoid device, particularly to fixing the connection portion between the outlet of the solenoid coil and the power supply lead wire.

[Conventional technology]

FIG. 1 is a sectional view showing a conventional electromagnetic solenoid device disclosed in, for example, Japanese Utility Model Application Publication No. 50-141161. In the figure, 1 is a yoke, 2 is a mounting screw provided at the end of this yoke 1, 3 constitutes a magnetic circuit together with the yoke 1 and is attracted to the yoke 1; 4 is a rod provided on the plunger 3; 5 is a plate forming part of the magnetic circuit; 6 is the yoke 1; 7 is a solenoid coil wound around the bobbin 6; 8 is a cover fitted to the yoke 1;
9 is a gasket provided between the yoke 1 and the bobbin 6; 10 is the cover 8 and the bobbin 6;
and an O-ring 11 provided between the yoke 1 and the yoke 1.
12 is a terminal of a lead wire 13 which is fixed to the eyelet 11 by caulking.

As is well known, the operation of a conventional electromagnetic solenoid device is such that when a power source is connected to the lead wire 13, the solenoid coil 7 is energized and a magnetic closed circuit consisting of yoke 1 - plunger 3 - plate 5 - yoke 1 is formed, and the plunger 3 is attracted to the yoke 1, and the rod 4 is moved downward in the figure.

[Problem that the invention attempts to solve]

In conventional electromagnetic solenoid devices like the one above,
The connection between the outlet of the solenoid coil 1 and the power supply lead wire and the fixing of the connection are achieved by inserting the outlet of the solenoid coil 7 through the eyelet 11 and guiding it outward, and then attaching the terminal crimped to the eyelet 11. 1
It will be fixed integrally with 2. Therefore, there were problems in that the connection work was complicated, and the strength of the connection part was unstable, making it easy to derail.

This invention was made in order to solve these problems, and it is an electromagnetic solenoid device that facilitates the connection work between the outlet of the solenoid coil and the power supply lead wire, and also firmly fixes the connection. The purpose is to obtain.

[Means for solving problems]

The electromagnetic solenoid device according to this invention has a winding frame with
Two flanges are provided so as to form a groove in which the outlet of the solenoid coil and the power supply lead wire connected to this outlet can be fitted, and at least one of the flanges is connected to the other flanges. A rib is provided between which the connecting portion can be pressed and fixed.

[Effect]

In this invention, the solenoid coil and the power supply lead wire are directly connected, and the connection part is pressed and fixed with a rib, so the connection work is reliable and easy.
In addition, the connection portion is firmly fixed.

〔Example〕

Figures 2, 3, and 4 a and b are an external perspective view of the main parts, an explanatory view of the manufacturing process, a top view of the main parts, and a side view, respectively, showing an embodiment of this invention, and 14 is a resin mold. It is a winding frame (bobbin) made of aluminum, which includes a cylindrical part 16 on which the coil 15 is wound as described later, a flange part 17 that abuts and engages both ends of the coil 15, and a notch groove provided in this flange part. 18. A second flange 19 formed on the outer side of the flange 17; a wedge-shaped rib 20 protruding from the second flange 19 as shown in the drawings [disposed at two opposing locations as described later]; It is integrally constituted by the groove 21 and the groove 21. The winding frame 14 shown in FIG. 2 is wound with a coil 15, and the opening 15a at the beginning or end of winding (this may be a tap part) is led out from the notch groove 18, and the enamel coating is peeled off. It is connected (wound) to the end 22a of the lead wire (for power supply) 22, and soldered with solder 23 and a soldering iron 24. The soldered portion is press-fitted in the direction of arrow P [and is elastically fitted into the narrow U-shaped groove formed between the rib 20 and the flange 17. ], as shown in FIGS. 4a and 4b, the connecting portion C between the lead wire 22 is fixed, and the solenoid 25 is obtained. Note that symmetrically arranged 18a is a notch groove,
20a is a rib, and 21a is a groove. Further, the lead wire 22 is led out of the casing as it is (no connection point is provided) and connected to a power supply device (not shown).

According to the above, the lead wire can be fixed with a simple configuration, and by configuring the rib 20 in a wedge shape, tensile force from the outside can be firmly received, and the cost of the device can be reduced.

Also, although not explained above, the lead wire 2
2 is preferably led out from a notch provided in the second flange 19 in a direction perpendicular to the winding frame (vertical direction as explained in the conventional device shown in FIG. 1).

[Effect of idea]

As explained above, this invention provides two flanges on the winding frame so as to form a groove in which the outlet of the solenoid coil and the power supply lead wire connected to this outlet can be fitted, and By providing a rib on at least one flange that can press and fix the connection between the other flange, it is easy to connect the solenoid coil and the power supply lead wire, and the connection is firmly fixed. It has the effect of allowing you to go to
