Abstract

A complex electromagnetic relay including a plurality of relay structures configured respectively as relays independent of each other, each relay structure including an electromagnet assembly and a contact section acting to open or close in accordance with an operation of the electromagnet assembly; and a housing accommodating the relay structures in a mutually inverted orientation with contact sections of the relay structures being located alternately at opposing sides. The electromagnet assemblies in the relay structures are provided individually with bobbins supporting coils. The housing includes an enclosing wall enclosing the relay structures in an envelope-like manner and a partition wall arranged between the relay structures disposed side-by-side to separate the relay structures from each other. The bobbins of the electromagnet assemblies are fixedly attached to the enclosing wall as well as to the partition wall.

Claims

1. A complex electromagnetic relay comprising:

a plurality of relay structures configured respectively as relays independent of each other, each relay structure including an electromagnet assembly and a contact section acting to open or close in accordance with an operation of said electromagnet assembly; and

a housing accommodating said relay structures in a mutually inverted orientation with contact sections of said relay structures being located alternately at opposing sides;

wherein electromagnet assemblies in said plurality of relay structures are provided, individually, with bobbins supporting coils;

wherein said housing includes an enclosing wall enclosing said plurality of relay structures in an envelope-like manner and a partition wall arranged between said relay structures disposed side-by-side to separate said relay structures from each other; and

wherein said bobbins of said electromagnet assemblies are fixedly attached to said enclosing wall as well as to said partition wall.

2. A complex electromagnetic relay as set forth in claim 1, wherein said housing defines a plurality of receptacles between said enclosing wall and said partition wall;

and wherein said complex electromagnetic relay further comprises locating elements provided respectively in said plurality of receptacles of said housing, for constraining said relay structures into an mutually inverted orientation in said receptacles.

3. A complex electromagnetic relay as set forth in claim 2, wherein said locating elements comprise protrusions protruding in said plurality of receptacles of said housing in a mutually opposing positional relationship.
