Description

[Detailed description of the invention] The present invention is a high voltage generator used to ignite gas, etc. by the high voltage generated by applying an impact force to a piezoelectric element. It is characterized by guiding.

An example of a conventional high voltage generator is shown in FIG.
In the figure, 1 is a piezoelectric element, 2 is the piezoelectric element 1
3 is an insulating outer case that houses and fixes the piezoelectric element 1, etc., and 4 is a receiving plate made of a conductive material that fixes the piezoelectric element 1 and forms one of the electrodes. The guess money is 5, the guess money is 4
A conductive impactor 6 is a pressing member that houses the impactor 5 and the conductive impact spring 7 and is slidably attached to the outer case 3, and is made of a conductive plastic material. has been done. 8 is a return spring for returning the pressing member 6 to the state before pressing, and 9 is a device pressing member made of a conductive material which becomes one electrode of a device used such as a lighter.

FIG. 2 shows another conventional example in which an insulating pressing member 10 is used, and a metal workpiece is placed between the pressing member 10 and the instrument pressing member 9 to guide the other electrode from the piezoelectric element 1. The protrusion of the connector 11 press-fitted into the through hole 10a of the pressing member 10 and the impact spring 7 are brought into contact with each other by interposing the electrode extraction connector 11.

These conventional examples had the following drawbacks. First, in the case of FIG.
is made of conductive plastic material, which is expensive, and since the receiving plate 2, which serves as one electrode, and this pressing member 6 are close to each other, external discharge cannot occur on the creeping surface of the outer case 3. There was an element of instability in practical use. Also,
In the case of FIG. 2, since the electrode extraction connector 11 is a metal workpiece, the contact with the impact spring 7 becomes incomplete due to slight variations in component accuracy, which increases the cost and causes inconvenient difficulties. .

The present invention has been devised to solve the above-mentioned problems, and an embodiment thereof will be described below with reference to FIG. 3, with the same numbers assigned to the same parts as above.

In the present invention, a conductive pressing member 10 is used,
A conductive rubber material 12 is press-fitted into the through hole 10a of the pressing member 10, and one electrode guided from the pad 4 is guided to the conductive rubber material 12 via the impactor 5 and the impact spring 7, and then (In this case, it is configured to be taken out to the instrument pressing member 9). Here, if the diameter and thickness of the through hole 10a made in the pressing part of the pressing member 10 are made slightly smaller than the diameter and thickness of the conductive rubber material 12, the conductive rubber material 12 will be press-fitted into the through hole 10a. At the same time, the device is constantly compressed by the impact spring 7 and the device pressing member 9, such as a lighter, so that it can be easily attached, securely locked, and securely electrically connected.

The present invention is constructed as described above, and one electrode of the piezoelectric element is guided to the outside using a conductive rubber material press-fitted into a through hole of an insulating pressing member. It is possible to reliably take out the generated high voltage to the outside of one of the electrodes without increasing the cost of parts.
