JPS6034931Y2 - High voltage generator - Google Patents

Description

[Detailed description of the invention] The present invention relates to a high voltage generator, and its purpose is to provide a high voltage generator that is extremely easy to assemble and is mainly used for igniting gas stoves, gas water heaters, etc. That is.

A conventional high voltage generator has an abbreviated cam on the outer box and a cam with a tapered part on the inner box, and presses the inner box and compresses the hammer spring, and the cam engages the hammer pin. It is a mechanism to solve the problem.

In FIGS. 2 to 4, 1 is a piezoelectric element, 2 is a spacer, 3 is a receiver having a protrusion 3a in part, 4 is an object to be hit,
5 is an outer box, and on the outer periphery of this outer box 5 there are abbreviated cams 5a,
A hole 5b for taking out the ground plate is provided.

Reference numeral 6 denotes an inner box, which is inserted into the outer box 5 and has a cam 6a having a tapered portion.

A hammer 7 has a hammer pin 7a, and is inserted into the hole in the inner box 6.

8 is a twisted hammer spring, 9 is a return spring,
It is biased to push back the inner box 6.

Reference numeral 10 denotes a grounding plate provided on the inner circumferential surface of the outer box 5, and has a hole 10a for fitting the hit object.

In addition, in order to combine the inner box and the outer box, after combining the inner box 6 and the outer box 5, insert the hammer pin 7a into the hammer 7, and caulk the hammer pin 7a to prevent it from falling off. Also, as shown in the figure, there is one in which a hammer spring 8 and a hammer 7 are housed in an inner box 6, and then a hammer pin 7a is inserted and caulked.

In this case, the inner box must be inserted in such a way that the hammer pin 7a passes through the groove from the end surface of the outer box that reaches the abbreviated cam 5a of the outer box 5, and the inner and outer shapes of both the inner and outer boxes are Since it is approximately square, the hammer pin 7a must be twisted in the opposite direction against the torsion force of the hammer spring 8 to insert it into the outer case, resulting in poor workability.

This invention solves the above-mentioned difficulties by changing the shapes of the inner and outer boxes so that when inserting the inner box into the outer box, they can be assembled by simply twisting the inner box body slightly. did.

The configuration will be described below with reference to the accompanying drawings showing the main parts.

Among the numbers 1 to 10, the same parts indicate the same parts as in the conventional example.

In the outer box 5, 5c is an abbreviated cam 5 extending from the edge of the outer box.
A guide groove for the hammer pin 7a formed to reach point a, 5d
is a circular inner circumferential wall, and 5e is a rectangular inner circumferential wall following the circular inner circumferential wall.

Further, in the inner box 6, 6b indicates a circular outer circumference, and 6c indicates a rectangular outer circumference.

These 5d, 5e and 6b, 6c are formed so that they can be fitted at corresponding positions.

Since the present invention has the above structure, when assembling the inner box and the outer box, the hammer pin 7a is inserted into the guide groove 5c of the outer box 5.
This can be completed by pushing the inner box 6 into the outer box 5 (in the A direction) so that the hammer pin 7a fits into the oval-shaped cam 5a (in the B direction).

Therefore, the inner box and the outer box can be assembled very easily, workability is greatly improved, and the practical effect is great.
