Abstract

PURPOSE:To preclude the occurrence of momentary break etc., when a large vibration or shock is applied, by forming a tab at a two-side contact or edge near it of a movable contact spring tied with a common terminal, and putting the free end of the tab always in contact with a protrusion step face furnished at a bobbin. CONSTITUTION:When no current is fed to the coil 21b of a relay 6, i.e., when a common terminal 72a-2 is in connection with a break contact terminal 22c, a movable contact spring 72a is put in a stabilized state by a tab 72a'. Accordingly the spring 72a itself will not cause vibration or resonance even though a vibration or shock is applied externally which permits the suppression of the momentary break phenomenon on the break contact terminal side and the circuit changeover phenomenon caused by contacting with the make contact terminal 22d. When current is fed to the coil 21b, on the other hand, the amperage or the shape of tab 72a', for example its width, are set so that the tab 72a' bends also, and thereby stable changing-over of the circuit is achieved.

するようになっている。Further, the tongue-shaped double-sided contact area 22c- 1 as the movable contact of the movable contact spring 22c is located above the drawing due to the elasticity of the movable contact spring 22c when no current is applied to the coil 21b. Then, the contact area of the break contact terminal 22e located on the upper side is contacted, but when a predetermined current is applied from the two external connection terminals 21c to the coil 21b, the attraction force generated on the armature side end surface of the iron core (not shown) is generated. The armature 22b described above, and thus the armature 22
Since the tongue-shaped double-sided contact area 22c -1 of the movable contact spring 22c fixed to b is attracted downward in the drawing against its spring property, it contacts the contact area of the make contact terminal 22d located below it. It is like this.

It becomes impossible to secure a stable connection between the contact area of 22c -1 and the break contact terminal 22e, resulting in a momentary disconnection between the common terminal 22c -2 and the break contact terminal 22e. There is a problem that the common terminal 22c -2 and the make contact terminal 22d may come into contact with each other.

とができる。On the other hand, if the relay is configured so that the tongue-shaped double-sided contact area of the movable contact spring does not separate from the break contact terminal even when vibration or shock is applied, the common terminal, and hence the movable contact spring and the break contact terminal, are connected. It is possible to suppress the momentary interruption of power supply and unexpected contact between the common terminal and the make contact terminal.

うに該リレーを構成している。Therefore, in the present invention, a tongue protruding from the tongue-shaped double-sided contact area of the movable contact spring connected to the common terminal is formed near the tongue, and the free end of the tongue is always the bobbin 21a. The relay is configured so as to come into contact with the convex step surface provided on the upper flange.

きる。This means that the movable contact spring supported by the tongue is unlikely to vibrate or resonate even when a large vibration or shock is applied. As a result, the movable contact spring and, by extension, the common terminal and the break. Instantaneous disconnection between the contact terminals and contact between the common terminal and the make contact terminal can be suppressed, and the attraction force of the armature generated by the current flowing in the coil is set to exceed the spring property of the tongue piece. The connection between the break contact terminal and the break contact terminal can be switched to the connection between the common terminal and the make contact terminal.
