JPH0315131A - Trigger pulse input on/off holding electromagnetic relay - Google Patents

Abstract

PURPOSE:To reduce a coil current for holding a contact by arranging a contact A which is the iron core of a movable coil portion between 2 fixed magnets where homopoles face each other and adhering a contact B to the respective magnets facing each other. CONSTITUTION:When a contact-A 5 which is the iron core of movable coils 5, 6 is arranged between two fixed magnets 3, 4 where homopoles face each other and a current is made to flow to a coil 6, both ends of the iron core 5 of the movable coils 5, 6 are polarized into N pole and S pole and magnetized with the result that the movable coils 5, 6 are attached to either of the fixed magnets, by the use of which the contact-A 5 and a contact-B 1, or the contact- A 5 and a contact-B 2 are turned ON/OFF. Thereby, it is possible to hold the contact-A 5 at a side of the contacts-B 1, 2 as desired.

This is the end of a moving coil type 1L magnetic relay that performs OFF operation.

With conventional technology (well, electromagnetic relays are movable type 06 type relays, hinge type relays, reed relays, etc.), but as you can see, the electric field (two fields) created by passing current through a coil is J is the quib that subtracts the possible wI layer point, and O of the live point is

Claims (1)

[Claims] A movable coil part (5) (6) is placed around an iron core with the N poles or S poles of one or two ferrite magnets (3) (4) facing each other and leaving a gap between them. The iron core (5) is also used as the A contact (5), and the facing magnets (3) and (4) have movable B contacts B1 (1) and B2 (2) glued to them. Coil type electromagnetic relay. (Figure 1)
