Problems solved by technology

In general applications, a single set of relays will be used to cut off the live wire or the neutral wire. From a safety point of view, if a relay can cut off the live wire and the neutral wire at the same time, its safety factor will be greatly improved, but in the above height and installation area Under limited circumstances, with the current technical conditions, only a single group of 16A load switching capability can be achieved, while the load capacity of a double group of relays can only reach 8-10A

Embodiment 1

[0024] Embodiment 1: As shown in the figure, an ultra-small 16A load level double-pole single-throw magnetic latching electromagnetic relay includes a base 1, a casing 2, an electromagnetic system 3, a contact system and a magnetic package 4, and the contact system includes a side-by-side arrangement The first dynamic and static contact group and the second dynamic and static contact group, the base 1 is integrally provided with a horizontal isolation plate 11 and a vertical isolation plate 12, the vertical isolation plate 12 is located below the horizontal isolation plate 11, the horizontal isolation plate 11 and the vertical isolation plate The isolation plate 12 divides the base 1 into a first installation cavity 13, a second installation cavity 14 and a third installation cavity 15, the length direction of the first installation cavity 13, the length direction of the second installation cavity 14, the length direction of the third installation cavity 15 The three in the len...

Embodiment 2

[0025] Embodiment 2: As shown in the figure, other structures are the same as Embodiment 1. The difference is that the structure of the moving contact group 5 is different: the moving contact group 5 includes a moving reed 51, a moving spring lead-out pin 52 and a moving contact 53. The reed 51 includes an upper reed 511 and a lower reed 512 stacked up and down, one end of the upper reed 511 and one end of the lower reed 512 are riveted and fixed with the moving spring lead-out pin 52, the other end of the upper reed 511, the lower The other end of the reed 512 is riveted and fixed with the movable contact 53. The upper reed 511 is integrally provided with an arc-shaped upper buffer plate 513, and the lower reed 512 is integrally provided with an arc-shaped lower plate located below the upper buffer plate 513. There is a gap 515 between the upper buffer sheet 513 and the lower buffer sheet 514, the upper buffer sheet 513 and the lower buffer sheet 514 are provided with a slot 5...

Abstract

The invention discloses a subminiature 16A load level double-pole single-throw magnetic latching electromagnetic relay. The magnetic latching electromagnetic relay comprises a base, a cover shell, an electromagnetic system, a contact system and a magnetic pack, wherein the contact system comprises a first movable and static contact group and a second movable and static contact group which are arranged side by side; the magnetic latching electromagnetic relay is characterized in that a horizontal isolation plate and a vertical isolation plate are integrally arranged on the base; the vertical isolation plate is positioned below the horizontal isolation plate; the base is divided by the horizontal isolation plate and the vertical isolation plate into a first mounting cavity, a second mounting cavity and a third mounting cavity; the first mounting cavity is used for mounting the electromagnetic system; the second mounting cavity and the third mounting cavity are arranged side by side; the second mounting cavity is used for mounting the first movable and static contact group; and the third mounting cavity is used for mounting the second movable and static contact group. The double-pole single-throw magnetic latching electromagnetic relay has the advantages of achieving the 16A load level, and realizing subminiature (the height is less than 13mm and the mounting width is les than 16mm) and high safety.

Description

technical field [0001] The invention relates to an electromagnetic relay, in particular to an ultra-small 16A load level double-pole single-throw magnetic latching electromagnetic relay. Background technique [0002] As a relay electronic component that controls strong signals through weak signals, relays are widely used in industrial control, household appliances, automobiles and other fields, and gradually form a well-defined development generation. The installation area is getting smaller and smaller, the load capacity is getting stronger and the reliability is getting higher and higher. [0003] In the field of 16A load switching, represented by home appliances, the typical height is less than 13mm, and the installation width is less than 16mm. It is widely used in occasions with strong inrush currents such as lamp loads, motor loads, electronic ballast loads, and solenoids. . In general applications, a single set of relays will be used to cut off the live wire or the ...
