Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a high voltage generator used for gas ignition of cigarette lighters and the like.

Background Art In recent years, cigarette lighters in particular have become mainstream, with a wide variety of types and low prices. In order to accommodate this, the reality is that high voltage generators of various sizes must be available. especially,
Many products have different lengths of high-voltage lead wires, and this is a major factor in increasing costs.

A conventional high voltage generator will be described below with reference to the drawings.

A conventional high voltage generator of this type had a configuration as shown in FIG. In Fig. 2, reference numeral 1 denotes an outer box, in which a pad 2, a piezoelectric element 3, and a receiver 4 are arranged, and a spacer 5 is press-fitted to pressurize them. The high-voltage lead wire 7 inserted through the wire insertion hole 6 and one end of the spacer 5 are electrically connected to each other, and in this state, they are impregnated and fixed with resin 8.

Further, after inserting the return spring 9 into the other opening of the outer box 1, the hammer pin 10 and the hammer 1 are inserted.
1. An inner box 13, which constitutes an impact mechanism using a hammer spring 12, is attached.

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

Now, when the inner box 13 is pressed, the hammer spring 12 configured inside the inner box 13 is compressed and stores impact energy. When the pressure is further applied, the hammer pin 10, which penetrates into the hammer 11 at a certain stroke and is engaged with a cam part (not shown) provided in the outer box 1, is inserted into the tapered hole of the inner box 13 (not shown). (not shown). Thereby, hammer 1
1 applies an impact to the piezoelectric element 3 via the pad 2 due to the impact energy stored by the hammer spring 12 being compressed, and a high voltage is generated from the piezoelectric element 3.
This generated high voltage is taken out from the high voltage lead wire 7 via the receiver 4 and the spacer 5.

Furthermore, after that, when the pressure on the inner box 13 is released,
The inner box 13 is returned to its original position by the return spring 9, and at the same time, the hammer pin 10 is also reset to a cam portion (not shown) provided on the outer box 1.

Problems to be Solved by the Invention In this conventional configuration, the high voltage lead wires are impregnated with resin while in contact with the spacer, so they cannot be replaced, and the difference in lead wire size alone makes it difficult to replace the high voltage lead wires. In addition, it was necessary to prepare many types of wires, and the lead wires became clumsy, creating unnecessary trouble.

The present invention is intended to solve these problems, and aims to make it extremely easy to replace the lead wires.

Means for Solving the Problem In order to solve this problem, the present invention has developed a method in which a conductive rubber is arranged deep inside the high voltage lead wire insertion hole provided in the box-shaped case, and a piezoelectric wire arranged inside the box-shaped case. One end of a spacer that presses the element and the pads and receivers disposed at both ends of the piezoelectric element is electrically connected to the conductive rubber.

Function With this configuration, conduction with the piezoelectric element can be established simply by inserting high voltage lead wires of various sizes through the high voltage lead wire insertion holes, and replacement can also be performed freely.

Embodiment FIG. 1 is a sectional view of an embodiment of the present invention. In FIG. 1, 14 is an outer box;
4, a piezoelectric element 15 is placed in the center, and a pad 26 and a receiver 17 are arranged at both ends of the piezoelectric element 15, and a spacer 18 is press-fitted to apply pressure thereto, and in this state, the piezoelectric element 15 is impregnated and fixed with a resin 19. Further, a conductive rubber 21 is disposed at the back of the high voltage lead wire insertion hole 20 of the outer box 14, and one end of the spacer 18 is electrically connected to the conductive rubber 21.

Further, after inserting the return spring 22 into the other opening of the outer box 14, the hammer pin 23 and the hammer 2 are inserted.
4. An inner box 26, which constitutes an impact mechanism using a hammer spring 25, is slidably attached.

The operation will be explained below. First, the operation of pressing the inner box 26, thereby applying an impact force to the piezoelectric element 15, and generating a high voltage is the same as that of the conventional example, so a description thereof will be omitted.

Thereafter, the high voltage generated by the piezoelectric element 15 is passed through the receiving plate 17 and the spacer 18 to the spacer 1.
The high voltage can be easily taken out by bringing a high voltage lead wire (not shown) inserted through the high voltage lead wire insertion hole 20 into contact with the conductive rubber 21. be.

Note that the subsequent return operation by releasing the pressure on the inner box 26 is also the same as in the conventional example, so a description thereof will be omitted.

Effects of the Invention As described above, according to the present invention, conductive rubber is arranged at the back of the high voltage lead wire insertion hole provided in the box-shaped case (outer box), and the piezoelectric element is arranged inside the box-shaped case. By connecting one end of the spacer that presses the pads and receivers placed at both ends of the piezoelectric element to the conductive rubber, the lead wires can be replaced freely and quickly in response to user requests. In addition, the lead wires do not become jammed during assembly, which improves work efficiency, so that the number of man-hours can be reduced.
