Abstract

PURPOSE:To absorb reaction at a time, when an impactor gives a piezoelectric element impact force through a patch, by resin layers, and to obtain high-voltage pulses only of stable one wave by preventing the bound of the impactor by forming the impactor in three-layer structure and shaping the resin layers among three layers. CONSTITUTION:When an inner box 5 is pushed in the A direction, an impact spring 7 is compressed elastically because an impact pin 8 inserted into a metallic section 6C for an impactor 6 having three-layer structure is engaged with a cam section fitted to an outer box 1. When the operation of predetermined stroke pushing progresses, a tapered section formed to the inner box 5 releases the impact pin 8 fastened to the cam section for the outer box 1. Consequently, a metallic section 6a for the impactor 6 having three-layer structure gives a piezoelectric element 2 impact force through a patch 3 by the elastically compressed impact spring 7, and high voltage is generated in the piezoelectric element 2. One of generated high voltage is extracted from a carrier 4 and the other from the impact spring 7 through the patch 3 and the impactor 6.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a high voltage generator used in a transmitter of a wireless remote control.

Conventional configurations and their problems In recent years, high voltage generators used in wireless remote control transmitters have become capable of error-free transmission by reliably generating only one wave of more stable high voltage pulses.

Is the drawing below? A conventional high voltage generator will be explained with reference to the following.

FIG. 1 shows a cross-sectional view of a conventional high voltage generator.

1 is an outer box including a piezoelectric element 2, a stopper 3, and a receiver 4; 5 is an inner box inserted into the outer box 1 and provided with an impactor 6, an impact spring 7, and an impact pin 8; 9 is a return spring.

The overvoltage generating device configured as above will be explained.

First, when the inner box 5 is pressed in the inward direction, the impact pin 8 inserted into the box 13 is engaged with a cam portion provided on the outer box 1, so that the impact spring 7 is compressed.

As the stroke suppression operation progresses, a portion of the taper provided on the inner box 5 releases the impact pin 8 that is locked to the cam portion of the outer box 1. Therefore, the one-handed hammer 6 applies a force to the piezoelectric element 2 via the stopper 3 due to the bow spring 7 under bow shell pressure, and a high voltage is generated in the piezoelectric element 2. The generated high electric shock is -F is from the receiver 4, the other is t and the receiver is 3,
It is taken out from the impact spring 7 via the impactor 6. Thereafter, when the suppression is released, the inner box 5 is returned to its original position by the return spring 9, and the hammer pin 8 is again locked to the cam portion.

However, in the above configuration, when the impactor 6 applies an impact force to the pad 3, the impactor 6 bounces, and the second and third waves of high voltage are generated as shown in FIG. However, when such a high voltage is generated, a second or third wave signal is generated from the wireless remote control transmitter with one operation, resulting in a malfunction on the receiver side.

Purpose of the Invention In view of the above drawbacks, the present invention aims to prevent the impactor from bouncing when it applies an impact force to the piezoelectric element through the stopper, and to reliably generate only one stable high voltage pulse. The present invention provides a high voltage generator that can perform the following functions.

Structure of the Invention In order to achieve this object, the high voltage generator of the present invention has a three-layered structure with an insulating metal layer and a resin layer in between.
With this configuration, the resin layer absorbs the recoil when the impactor applies impact force to the piezoelectric element via the pad, and by preventing the impactor from bouncing, a stable high voltage pulse of only one wave is obtained. It is something that can be done.

DESCRIPTION OF EMBODIMENT 1 Hereinafter, a high voltage generator according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 3 shows a sectional view of a high voltage generator according to an embodiment of the present invention. 1 is a piezoelectric element 2, a pad 3,
An outer box 5 is provided with a receiving plate 4, and a resin layer 6bf, an impactor 6 consisting of three layers (interposed between , an inner box comprising impact pins 8, and 9 is a return spring.

The operation of the high voltage generator configured as described above will be described below.

First, when the inner box 5 is pressed in the inward direction, the metal part 60K of the three-layered impactor 6 and the tlTt impactor 8 are locked to the cam part provided on the outer box 1. The impact spring 7 is compressed. As the constant stroke pressing operation progresses,
A portion of the taper provided on the inner box 6 releases the impact pin 8 locked to the cam portion of the outer box 1.

Therefore, the compressed impact spring 7 creates a three-layer impactor 6.
The metal portion 6 & applies an impact force to the piezoelectric element 2 via the pad 3, and a high voltage is generated in the piezoelectric element 2. The generated high voltage is extracted from the receiver 4 on one side, and the impact spring 7 via the pad 3 and impactor 6 on the other side.

In this way, since the impactor 6 has a three-layer structure, when an impact force is applied to the pad 3, the resin layer 6b of the impactor 6 absorbs all of the recoil, so it does not bounce, as shown in Figure 4. As such, high voltage of the 2nd wave and 3rd wave is not generated, and the wireless remote control transmitter does not generate the 2nd wave and 3rd wave signal with a single operation, and there is no possibility of malfunction on the receiver side. It will disappear.

Effects of the Invention As described above, according to the present invention, the impactor has a three-layer structure, and by providing a resin layer between them, the reaction when the impactor applies an impact force to the piezoelectric element through the pad is suppressed. Absorbed by resin layer,
By preventing the impactor from bouncing, it is possible to obtain a stable high-voltage pulse with only one wave, making it possible to create a transmitter that does not malfunction, which has great practical effects.
