Problems solved by technology

[0014] However, since the inspector decides to turn the adjustment screw to the right or left based on the sound he hears, it takes time for inexperienced inspectors to adjust.
That is, skilled inspectors are required
[0015] In addition, when the part accuracy or assembly accuracy is poor, and the deviation of the contact gap is large, it takes time to adjust even for skilled inspectors.
[0016] And, as in Patent Document 2 Image 6 As shown, the part of the contact gap after assembly is inside the flat electric alarm 1, and it is difficult to visually inspect

Embodiment Construction

[0048] Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. In addition, the drawings are viewed according to the direction of the reference numerals. In addition, all the screws will be described as right-handed screws.

[0049] figure 1 It is a cross-sectional view of a flat siren as an object to be adjusted according to the present invention. The flat alarm 10 accommodates a fixed iron core 12 and an exciting coil 13 in a flat housing 11, and makes the adjusting screw 14 protrude into the housing 11, and uses the adjusting screw 14 to support the fixed contact 16 through the fixed contact rod 15, The movable contact 17 is arranged opposite to the fixed contact 16, the movable contact 17 is supported by the movable contact rod 18, and the movable contact rod 18 is biased in the contact closing direction by the spring 19, and the protrusion of the case 11 A vibrating plate 23 is placed on the edge 21 via a line...

Abstract

The provided gap adjustment method for a flat alarm comprises: 1. setting the original movable iron core as the zero position for detection; 2. moving the core toward fixed iron core only the target gap; 3. when the fixed and movable contact points are conductive, rotating the adjustment screw till on un-conductive state; 4. releasing limit to return to aero position. This invention is convenient for operator.

Description

technical field [0001] The invention relates to the contact gap adjustment technology of a flat alarm. Background technique [0002] Inexpensive and simple horns are widely used as devices for generating warning sounds (for example, refer to Patent Document 1). [0003] [Patent Document 1] Japanese Unexamined Publication No. 2001-287588 ( figure 1 ) [0004] In Patent Document 1 figure 1 Among them, 2 is a vibrating plate, 3 is a fixed iron core, 4 is a movable iron core, 4b is a stepped part set on the movable iron core 4, 6 is an excitation coil, 7 is a fixed contact, 8 is a movable contact, 8a is a supporting movable The contact plate of the moving contact 8, 9 is the resonant plate, and G is the air gap. [0005] When the excitation coil 6 is energized, the movable iron core 4 is attracted by the fixed iron core 3 and moves downward in the figure. With this movement, the stepped portion 4b hits the contact plate 8a and moves downward in the figure. [0006] When th...
