Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fixing member for a coil in a hand-held vibrator.

[Prior Art] FIGS. 4 and 5 show an example of fixing means for a fixed core of an electromagnetic vibrator in a conventional hand-held vibrator.

FIG. 4 is a partially cutaway view of the E-shaped fixed core portion of the hand-held vibrator, viewed from the E-shaped side of the fixed core portion.

In the figure, 3 is a coil, and in the figure, the coil 3 is shown with a portion cut away so that the fixed core portion can be seen. 4 is a fixed core parent plate having an E-shape;
Reference numeral 5 denotes a coil attachment fitting having a bent portion, and numeral 6 denotes a core tightening screw for tightening the fixed core parent plate 4 and the coil attachment fitting 5 to the core 1.

Figure 5 is a sectional view taken along Y-Y' line in Figure 4.
The three projections of the E-shaped fixed core base plate 4 depicted in the figure are shown with their heads facing upward.

In the figure, 1 is a fixed core. Other symbols are the same as those in FIG. 4, so explanations will be omitted.

In this configuration, the coil 3 is attached to the coil fixing fitting 5.
It is fixed with heat-resistant adhesive or the like.

The coil fixing fitting 5 has a bent portion in order to obtain strength for fixing the coil 3 to the fixed core 4.

[Problems to be Solved by the Invention] As described above, the conventional method has a drawback in that the coil mounting bracket 5 is required to fix the coil 3 to the fixed core 1.

[Means for Solving the Problem] A bent portion and a short piece portion continuous to the bent portion are provided at the head of the central leg portion of the fixed core parent plate 4, and the short piece portion is arranged approximately at right angles to the direction of the coil 3. It is bent and used as a fixing member for the coil 3.

[Function] As a result, the coil mounting bracket 5 is attached to the fixed core main plate 4.
This also makes it possible to have this function, and the coil mounting bracket 5 becomes unnecessary.

[Example] The present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a diagram of the internal structure of the hand-held vibrator, and FIG. 2 is a partially cutaway view of the E-shaped fixed core portion of the hand-held vibrator, viewed from the side of the E-shaped fixed core portion.

Figure 3 is a sectional view taken along line X-X' in Figure 4.
The three projections of the E-shaped fixed core base plate 4 depicted in the figure are shown with their heads facing upward.

In these figures, explanations of the same components as in the prior art will be omitted.

a is a bent portion provided at the head of the central leg of the E-shaped fixed core parent plate, and k is a caulked portion.

The bent portion a is continuously provided with a short piece portion.

Further, the bent portion a may be formed to be easily bent. For example, there is a method in which the portion is formed slightly thinner as shown in FIG. Further, as another example, the portion may be formed slightly thinner.

The stacked fixed cores 1 are caulked by the caulking portion k. At the same time, the fixed core 1 is also tightened with the core tightening screw 6. At this time, both ends of the fixed core 1 are necessarily narrowed by the fixed core parent plate 4.

After this crimping step, the coil 3 is attached to the fixed core parent plate 4 using a heat-resistant adhesive or the like.

After installing the coil 3, the head of the central leg of the fixed core parent plate 4 is bent at a point a, and the coil 3 is fixed to the short piece continuous to the bend a using a heat-resistant adhesive or the like.

[Effects of the invention] As described above, the present invention has the great effect of eliminating the need for the coil mounting bracket 5, which was conventionally necessary, and saving processing costs.

An accompanying effect of this effect is that since the fixed core 1 is tightened directly to the core parent plate 4, the degree of tightening of the fixed core 1 is higher than in the past, and the vibration resistance is improved.
