Debugging-free magnetic latching relay

Abstract

A debugging-free magnetic latching relay of the invention comprises a lower shell body, a magnetic driving module and a bridge dynamic module. The magnetic driving module drives the bridge dynamic module to do linear motion. The lower shell body comprises a magnetic driving module containing space and a bridge dynamic module containing space. The magnetic driving module containing space is used for precisely fixing the magnetic driving module. The bridge dynamic module containing space includes a movable magnetizer module containing space and a contact bridge module containing space. A movable magnetizer module is driven by the magnetic driving module to move in the movable magnetizer module containing space and drive a contact bridge module to do reciprocating motion in the contact bridge module containing space so as to close or open the magnetic latching relay. The movable magnetizer module moves to drive a contact bridge to be in contact with a pair of static contacts directly facing the contact bridge. The motion stroke of the movable magnetizer module is larger than the distance between the most front end of the contact bridge and the static contacts when the magnetic latching relay is in an open state.

Description

【Technical field】 [0001] The invention relates to the technical field of magnetic latching relays, in particular to a debugging-free magnetic latching relay. 【Background technique】 [0002] The magnetic latching relay is a closed or open state that is only held by the magnetic force generated by the permanent magnet in the coil magnetic circuit system, and the mutual conversion between the closed and open states only depends on the forward or reverse pulse voltage of a certain width to excite the coil The coil in the magnetic circuit system triggers the movement of the armature assembly to complete the electrical control device for opening and closing the reed contact unit. [0003] The existing magnetic latching relay consists of a magnetic circuit part, a pushing part and a base part. figure 1 It is a schematic structural diagram of a typical high-power magnetic latching relay. The static spring part 71 and the moving spring part 72 are installed on the base 70. The pushi...

Problems solved by technology

However, the structure of this kind of relay is complex and the production process is difficult. On the one hand, this directly increases the production cost. On the other hand, a manual debugging program must be added in the production process to ensure the reliability of the product as much as possible. However, manual debugging is easy. Affected by the debugger's own experience and many other uncontrollable factors, it will affect the reliability of the relay during use
