Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is particularly advantageous for electromagnetic relays with low high frequency loss. It is in /II4.

An embodiment of the present invention will be described below with reference to FIG. 11171fL.

The dot seal 1 is made of an elastic conductive metal material and is formed into a ring shape, and is fitted with a lid of a long fist (not shown) to shield the horse at the image point. Then, as shown in the iWA, the opposite value is 2.
Elastic pieces 4.4-... are raised from 5, and a notch S is formed in a part of the elastic pieces 4.4-. 11 at iI point 'i11, hole 6
．． 4,411%, and ground pieces 7, 7, etc. are cut and raised near both ends of this hole 60, respectively. A constant contact piece 8, which connects inside this hole 6, is erected on an insulating base 9 of the relay, and is insulated from the twill point 8 hole 4.

The movable body 10 has an insulating piece ■scq performance point piece 12 inserted therethrough. 1s is an electromagnetic block, and a movable piece of iron is attached to the iron core: u K, IL, and a hinge is threatened to the iron jacket so that it will be released.

Next, for assembly, the protrusion ha of the insulating piece 11 of the movable body 10 is loaded into the notch group of the contact point i[10 and the elastic piece 4, and the movable body 10 is elastically sandwiched between both elastic pieces 4 and 4. Elastic piece 10
With zero elasticity, it is possible to move forward in the direction of 1-m2ss. The two movable pieces to and 10 are tied together at one point by a separate S cord piece, and the facing wall 2, the other facing walls, and the ground piece 7, which may have been attached to a subsidiary company. 7t11t
The movable contact piece 12 is positioned at a position of 41mm outside the excitation point piece 12, and when the contact chamber 1 is placed on the insulating stand 9, the movable contact piece 12 is positioned between the facing point piece 8 and the earth piece 7. That's how it is.

The intermediate portion of the connecting piece 17 is suppressed and driven by the end 14M of the movable iron piece U.

However, the electromagnetic block brocade is energized and a movable piece of iron is created! 4 is iron core! -, the roadside 14m drives the movable body 10.10 via the crawler gauge. And elastic piece 4% 4tI
: As shown in Fig. 14, the second E left part of the movable contact piece 12 comes into contact with the fixed contact piece 8.8,
On the other hand, the one on the right comes into contact with the grounding pieces 7, 7, and the movable single point piece 12 on the right is grounded, causing Einreis.
When the excitation is stopped at the 0th order where the loss is minimal, the elastic pieces 4, 4
The movable body 10 returns with the self-returning force of , and the left movable contact piece 12 comes into contact with the grounding pieces 7, 7 again and is grounded, while the right one becomes the fixed contact piece 8.8 again! ! Because of this, when viewed from the central fixed contact piece 8, the fixed contact pieces B and 8 on the left and right sides are alternately 1II1'5. Here, the connecting piece 17 is removed and only one movable piece 10 is used.
One movable single-point piece 12 protruding from both ends of the movable piece 100 without being surrounded by @ is in stable contact with the fixed contact piece 8, a.

The ground terminal 71 is an insulator! Through hole? K so that it is outputted to the outside through 1 and grounded to the high frequency circuit outside the relay.
It is.

As explained above, according to the wA#c of the present invention, the movable body is sandwiched between the anti-flesh elastic piece formed integrally with the contact chamber and is driven by an electromagnetic block, so the movable contact can be moved without the movable piece tilting. Since the piece comes into contact with the fixed contact piece, the MM operation of the high frequency relay is stabilized, and the movable piece provides a return force, making it possible to easily operate without the need for additional parts.
