Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to extracting high voltage from a high voltage generator that generates high voltage by applying an impact force to a piezoelectric element.

A conventional high voltage generator of this type is shown in FIG. In FIG. 1, reference numeral 1 denotes an insulating housing containing one piezoelectric element 2, and 3 denotes a pad that receives a direct impact from an impactor, which will be described later. There is. 4 is storage body 1
A receiver 5 which is screwed together to hold and fix the piezoelectric element 2 from the other end face is a high voltage lead wire for extracting a high voltage from the piezoelectric element 2. 6 is the above storage body 1
This is an insulated operating body that is housed in a reciprocating manner within the operating body 6, and within this operating body 6 is an impactor 7 for applying an impact force to the stopper 3 of the piezoelectric element 2, and an impactor 7 for applying an impact force to the impactor 7. An impact spring 8 for storage is housed. Reference numeral 9 denotes a return spring housed in the housing 1, and this spring 9 has a biasing force that constantly pulls the operating body 6 away from the piezoelectric element 2 side. Also, although not illustrated as is usually well known,
The pin protruding from the impactor 7 is the storage body 1 and the operating body 6.
An impact mechanism is configured by engaging the cam window formed in the cam window.

Conventional high voltage generators are configured in this way, and the high voltage from the piezoelectric element is led to the outside using a high voltage lead wire. However, in reality, with this configuration, it is difficult to insert the high voltage lead wire into the storage body and to connect the high voltage lead wire to the piezoelectric element.

Therefore, the present invention aims to provide a high voltage generator with a simple and reliable configuration that solves these problems.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 2 and 3, with the same numbers assigned to the same parts as above.

As shown in FIG. 2, in the present invention, only one piezoelectric element 2 is housed in the housing 1, and the conventional high voltage lead wire is not used. In addition, a hole 6a having a diameter slightly larger than the inner diameter of the impact spring 8 is provided on the end surface of the insulating operating body 6 opposite to the piezoelectric element 2 side.
is formed. A high voltage terminal 10 can be inserted and fixed into this hole 6a.

Now, when the above-described impact mechanism is used to apply an impact force to the pad 3 using the impactor 7 using the impact spring 8, the piezoelectric element 2 generates a high voltage. At this time, one side of the high voltage is guided to the outside via the receiver 4, while the + side is guided to the pad 3, impactor 7, and impact spring 8, but is not led to the outside as it is. Therefore, in the present invention, the high voltage terminal 10 is inserted and fixed into the hole 6a formed in the operating body 6, which has a diameter slightly larger than the inner diameter of the impact spring 8, so that the high voltage on the + side can be easily guided to the outside. It is something that

Here, the reason why the hole 6a is made to have a slightly larger diameter than the inner diameter of the impact spring 8 is that the high voltage terminal 10 is installed from the outside after the impact spring 8 is assembled (that is, after the high voltage generator is assembled). Therefore, if the structure was such that the high voltage terminal was inserted from the direction of the impact spring 8 before the impact spring 8 was assembled, the assembly would not only be complicated, but also the shape of the high voltage terminal itself would be restricted. will have. Furthermore, if the hole 6a has a diameter that is equal to but slightly smaller than the inner diameter of the impact spring 8, problems may occur such as incomplete connection between the high voltage terminal 10 and the impact spring 8.

Furthermore, the reason why the operating body 6 is made of insulating material in the present invention is that the exposed area of the operating body 6 from the storage body 1 becomes large, and when it is made conductive, there is a gap between it and the high voltage on the + side. The means for complete insulation becomes complicated, and this imposes restrictions on the practical use of lighters and the like. Another reason is that as long as the material is insulating, it can be molded into any shape at low cost by resin molding.

As described above, the present invention has a hole with a diameter slightly larger than the inner diameter of the impact spring on the end face of the insulated operating body, so that a high voltage terminal of any shape can be inserted and fixed electrically securely. , which can easily lead high voltage to the outside.
