Description

[Detailed Description of the Invention] The present invention relates to a vibration switch in which a swing contact at the bottom of a swing rod is installed in a normal position at the center of a floating hole of a fixed point.

The vibration switch is housed in a housing so that it can swing freely by hanging its upper part on a hanging shaft that is rotatably supported on the upper part of the housing wall, and the swinging contact at the bottom is placed in a horizontal position at the bottom of the housing. The contact plate is loosely fitted into a floating hole provided through a fixed contact plate fixed to the contact plate. When installing this vibrating switch, the vibrating contact does not touch the fixed contact,
In order to position the fixed contact plate in the center of the floating hole, that is, to make the fixed contact plate horizontal, it was necessary to install a device or a measuring device for adjusting the horizontality or verticality. If a vibration switch is equipped with a horizontal/vertical adjustment device or measuring device, the vibration switch will become large and it may be difficult to install it compactly on various objects such as doors or in a fixed space. The cost of accessories is high, and the cost of the vibration switch increases. Therefore, the present invention has been developed to create a casing that houses the vibration rod and fixed contact plate of a vibration switch, in order to enable the vibration switch itself to be accurately and easily installed in its normal position without attaching any special equipment or measuring instruments to the vibration switch. is made of a transparent material, and collimation lines consisting of vertical gauge lines are provided on the front and side walls of the housing.

Hereinafter, the present invention will be described in detail based on specific embodiments shown in the accompanying drawings. FIGS. 1 to 4 show an embodiment of the present invention, and this switch S is assembled to an opening/closing notification device B attached to the top of the door A.

Reference numeral 1 indicates a rod, which is formed by punching out a plate material with good electrical conductivity, such as phosphor bronze.

A hanging hole 2 made of a circular hole having an axis running in the thickness direction is provided through the upper part of the swinging rod 1. This hanging hole 2
may be formed after punching, but it is advantageous in terms of cost to form them simultaneously with the contour during punching. The surface of the rod 1 is plated with gold if necessary.

A pendulum 3 is fitted onto the swing rod 1. This pendulum 3 is received by protrusions 4 provided on both sides of the lower part of the swinging rod 1 to prevent it from falling downward.

Reference numeral 5 indicates a hanging shaft, which is made of a wire material with good electrical conductivity, such as phosphor bronze, and is plated with gold if necessary.

A V-shaped bent part 6 is formed in the middle part of the hanging shaft 5, and the hanging shaft 5 is inserted into the hanging hole 2 of the swinging rod 1. Supports the hanging shaft 5.

The housing 7 is formed into a vertically long rectangle, and one horizontal side thereof is open. A guide pin 8 protruding from the open end surface is provided on the upper wall 7a and the lower wall 7b.
are molded and provided at the same time. The housing 7 is fixed to the opening/closing notification device B by inserting the guide pin 8 into a guide hole provided in the opening/closing notification device B and fixing it in a predetermined position with a screw or the like through a separately provided hole (not shown).

A fixed contact plate 9 made of a plate material with good electrical conductivity, such as phosphor bronze, is fixed in a horizontal position in the lower part of the housing 7 . The fixed contact plate 9 is plated with gold if necessary.

An elliptical floating hole 10 is provided through the fixed contact plate 9, and a swinging contact 11 formed from the lower part of the swinging rod 1 is fitted into the floating hole 10 so as to be movable. The minor axis of the floating hole 10 is located in a direction that coincides with the thickness direction of the swing rod 1. This setting is made because the swinging rod 1 is suspended from the V-shaped bent portion 6 of the hanging shaft 5, and swinging in the plate thickness direction is easier than swinging in other directions.

A lead wire connection part 12 exposed to the outside from the open end surface of the casing 7 is integrally connected to the hanging shaft 5 and the fixed contact 9. A lead wire (not shown) of the opening/closing notification device B is connected to each lead wire connecting portion 12 by a well-known method such as soldering or an outlet method.

When installing on the opening/closing notification device B, the swing contact 11
In order to be able to visually check and correct whether or not the housing 7 is installed in the normal position located at the center of the floating hole 10, the housing 7 is made of a transparent body.
A collimation line 14 made of a plumb line is provided on the front and side walls so as to coincide with the swing rod 1 if the housing 7 is attached in a normal position. By checking whether the collimation line 14 and the swing rod 1 match, it can be easily determined whether the housing 7 is attached in a normal position. The line of sight 14 is carved,
Indentation or protrusion molding, painting, etc. at the same time as housing molding,
It may be provided in any manner. Alternatively, it may be provided only on two adjacent horizontal side walls. Incidentally, in addition to or in place of the collimation line 14, a collimation line in the shape of a circle, a cross, or a combination thereof may be provided on the bottom wall of the casing 7.

FIG. 5 shows another embodiment of the present invention, in which fixed contact receiving grooves 13 are arranged in multiple vertical stages on the inner surface of the lower part of the casing 7, so that the height of the fixed contact plate 9 can be changed selectively. .

As mentioned above, the present invention is a vibration switch in which the swing contact at the bottom of the swing rod is loosely fitted into the floating hole of the fixed contact plate and housed in the housing, and the housing is made of a transparent body. The set status can be confirmed directly by visual inspection. Furthermore, since sight lines are provided on the front and side walls of the housing, adjustment to the normal posture is extremely easy. Furthermore, according to the present invention, there is no need to attach special equipment or measuring instruments to attach the vibration switch to its normal position, and the vibration switch can be formed compactly and accommodated in a small space, and the vibration switch can be provided at a low cost.
