Description

[Detailed description of the invention] The present invention is a high voltage generator in which a piezoelectric unit is mounted on one side of a flat mounting plate, and an impactor and an impact spring that abuts the impactor are mounted on the opposite side of the mounting plate. The present invention relates to an improvement of the mounting plate.

A conventional high voltage generator will be explained with reference to Fig. 1. 1 is a mounting plate in which a long hole is bored in the longitudinal direction of a rectangular flat metal plate, and a piezoelectric cord 3 is attached to a cord outlet 2a on one side of the mounting plate. The unit 2 is inserted and fixed, and an impactor 4 is slidably supported on the other side opposite to the unit 2, and an impact spring 5 is supported by contacting the rear part of the impactor 4. The cam 6 is fitted into the rotating shaft 7, and the rotating shaft 7 is rotatably mounted on the mounting plate 1.
The tip of the cam 6 is in contact with the tip of the impactor 4 and is in a position to move the impactor 4 as the rotating shaft 7 rotates.

In the above configuration, when the rotating shaft 7 is rotated counterclockwise, the cam 6 moves the impactor 4, and the impact spring 5 is compressed to accumulate spring force. When the rotating shaft 7 is further rotated, the cam 6 separates from the impactor 4, and the impactor 4 uses the accumulated spring force to impact the piezoelectric unit 2 to generate a high voltage, and the high voltage cord 3
The flammable gas was ignited by a spark discharge at a discharge electrode (not shown) through the igniter.

In such a high voltage generator, since the mounting plate is a flat plate, the high voltage cord of the piezoelectric unit is oriented in the left and right direction with the mounting plate as a border, that is, the X-
It can only be taken out in the X-axis direction. For this reason, when installing it on gas appliances, etc., there are considerable restrictions due to the mechanical parts of the gas appliance, so extra parts,
This may require a lot of man-hours, and in some cases, only a limited amount of equipment can be attached due to space constraints.

The object of the present invention is to provide a high voltage generator with a mounting plate that solves the above-mentioned drawbacks.

An embodiment of the present invention will be described below with reference to the drawings.
In Fig. 2, reference numeral 11 denotes a mounting plate made of a rectangular metal flat plate (or plastic flat plate) with a long hole bored in the longitudinal direction, and one side of this long hole is used to connect the high voltage cord 3 to the cord outlet 2a. The piezoelectric unit 2 is mounted and fixed, and the other side is used for mounting an impact spring 5 that comes into contact with the rear portion of the impactor 4. At the high voltage cord lead-out position of the piezoelectric unit 2 on the mounting plate 11, a recess 11a for leading out the high voltage cord is formed transversely orthogonally to the elongated hole. It goes without saying that the recess 11a is formed larger than the diameter of the cord outlet 2a. A rotating shaft 7 having a piezoelectric unit 2, an impactor 4, an impact spring 5, and a cam 6 fitted therein is mounted on the mounting plate 11, respectively.

The operation is the same as described in FIG.

The high-voltage generator, which consists of a mounting plate with the above-mentioned concave portions, is designed so that the high-voltage cord of the piezoelectric unit can move in the left and right directions as shown by the Since it can be directed in any direction, the high-voltage cord will not get in the way when attached to gas appliances, etc.

As mentioned above, the high voltage generator according to the present invention allows the high voltage cord of the piezoelectric unit to be installed in the direction that matches the internal mechanism of the gas appliance, etc., so there are no restrictions on installation, and therefore no extra parts or man-hours are required. However, it has great practical effects.
