Embodiment Construction

[0021] Now in conjunction with accompanying drawing, the present invention will be further described.

[0022] Such as figure 1 , figure 2 As shown, the magnetic latching relay includes a base 1 and a case 10 , and an electromagnet core assembly 2 , a joystick assembly 3 , a moving plate assembly 4 , a first static piece 5 and a second static piece 6 are respectively arranged in the base.

[0023] The electromagnet core assembly 2 is fixed in the base 1, and includes an electromagnetic coil body 201 with a built-in iron core, and symmetrical yokes 202 are arranged at both ends of the electromagnetic coil body.

[0024] The main body of the joystick assembly 3 is an insulator 301, and the insulator is integrated with a shaft. One end of the shaft is pivoted and pivotally positioned on the base 1, and the other end is pivotally pivoted and positioned on the splint 9 inside the housing 10. The insulator wears Connect and fix two armatures 302 arranged in parallel and at interv...

Abstract

The invention relates to a magnetic latching relay with a large opening distance and high tolerance. The magnetic latching relay comprises a base, an electromagnetic iron core assembly fixed on the base, a first static sheet, a second static sheet, an operating rod assembly which swings relative to the base in a positioning manner, and a moving sheet assembly. The operating rod assembly is provided with an operating rod which swings synchronously, the moving plate assembly comprises a moving plate and a moving plate seat, the moving plate is fixed on the moving plate seat, the moving plate seat swings in a positioning manner relative to the base, the moving plate seat is provided with a linkage part linked with the operating rod, and when the moving plate seat swings to one of the limiting ends along with the operating rod, the moving plate seat drives the moving plate to be separated from the first static sheet to form disconnection, when the operating rod swings to the other limiting end, the moving plate seat drives the moving plate to make contact with the first static sheet to form guide connection, and in the guide connection state, the contact portion of the operating rod and the moving plate seat forms a swing dead point limiting active swing of the moving plate seat. According to the structure, the overall size is small, the opening distance between the movable piece and the static piece is large, continuous electric arcs are not prone to being generated, work is reliable and safe, and the service life is long.

Description

technical field [0001] The invention relates to a relay, which is a large opening distance and high tolerance magnetic latching relay. Background technique [0002] At present, the specifications of the most widely used mainstream magnetic latching relays in the market are between 63A and 100A. For example, the authorization announcement number CN20154104410U published in the Chinese patent literature, the authorization announcement date is September 1, 2010, and the name of the utility model is "a one-way magnetic latching relay", and the authorization announcement number CN201691767U published in the Chinese patent literature, the authorization announcement date On December 22, 2010, the name of the utility model was "a single-phase magnetic latching relay". The above two magnetic latching relays are the two most widely used structures. Due to the limitation of application space, their overall dimensions are basically 310 (length) × 30 (width) × 16.5 (height). Due to the ...
