The sucking-assistant spring sheet is assembled on the motion straight line of the driving member of the magnetic latching relay, so as to properly reduce the off confining force of the magnetic latching relay, improve the reverse force matching of the magnetic latching relay, reduce the sealing voltage of the magnetic latching relay when being actuated, and improve the electric property of the relay.

Description

What be used for magnetic latching relay helps the suction shell fragment

Technical field

The utility model belongs to technical field of electronic components, relates to a kind of booster action that is specifically designed to the magnetic latching relay closed action.The counter-force that this shell fragment can improve magnetic latching relay cooperates.

Background technology

Magnetic latching relay is a kind of under the effect of drive control signal, utilizes the interaction of solenoid and permanent magnet, relative motion to realize make-and-break contact.The control element that after drive control signal disappears, can still keep the state that is switched on or switched off.Characteristics with energy savings, working stability are widely used in electric system protection device and all kinds of telemechanical, remote control and the communicator.

For guaranteeing the reliability of magnetic latching relay work, need to improve the contact contact pressure of magnetic latching relay.Common magnetic latching relay, its moving contact assembly generally adopts cantilever leaf spring formula structure.Be subjected to the restriction of sheet spring applied stress, the counter-force of sheet spring is less than the contact pressure of contact during the magnetic latching relay off-state, so just cause magnetic latching relay closed inconsistent with the confining force that disconnects under the two states, make that the closure and the off voltage of magnetic latching relay are variant, influenced the performance of magnetic latching relay.

Summary of the invention

The purpose of this utility model be to provide a kind of be used for magnetic latching relay help the suction shell fragment.This helps the suction shell fragment can reduce the confining force of magnetic latching relay under off-state, can reduce the voltage of magnetic latching relay when closed action, improves the electric property of magnetic latching relay.

For realizing above-mentioned goal of the invention, the utility model adopts following technical scheme:

A kind of be used for magnetic latching relay help the suction shell fragment, its material adopts the metal material of high allowable stress good springiness, for example phosphor bronze, beryllium copper or stainless steel etc.

The described suction shell fragment that helps adopts the sheet spring structure.

The described suction shell fragment that helps, setting is positioned on the line of motion of driving member.

The described suction shell fragment that helps is by the impeller generation effect of magnetic latching relay.

When relay is closure state, describedly help that to inhale shell fragment be not compressed state of freedom, do not contact with driving member;

When relay was off-state, described helping inhaled the compression that shell fragment is subjected to driving member, and counter-force is acted on driving member;

The described suction shell fragment that helps should cooperate according to the suction of product and counter-force, and is reasonable in design, and suitable confining force when reducing magnetic latching relay and disconnecting has reduced the sealing voltage of magnetic latching relay.

Embodiment

Shown in Fig. 1 a and 1b, magnetic latching relay 1 is a kind of typical structure in the magnetic latching relay, and concrete is the utility model of 200720148710.4 " a kind of control magnetic latching relays " as the patent No., and its version is not just set forth one by one at this paper.

As Fig. 1 a, be a kind ofly to be useful for helping of described typical magnetic latching relay 1 and to inhale shell fragment 2 structures.

Described helping inhaled shell fragment 2 and is provided with and is fixed in the pedestal of magnetic latching relay 1.

Described helping inhaled shell fragment 2 its assemblings and is positioned on the straight line of driving member 3 directions of motion.

As Fig. 2 a, help the free end of inhaling shell fragment 2 towards driving member 3.

As Fig. 2 a, 2b, help the stiff end of inhaling shell fragment 2 to insert among the pedestal 4 holddown groove A.

As Fig. 3 a, described magnetic latching relay 1 is when closed operating state, and it helps suction shell fragment 2 to be in freedom, and state does not by compression help suction shell fragment 2 not contact with driving member 3, helps this moment suction shell fragment 2 not work.

As Fig. 3 b, when described magnetic latching relay 1 when disconnecting operating state, be subjected to the extruding of driving member 3, help that to inhale shell fragment 2 compressions stressed, help and inhale shell fragment and have counter-force to act on driving member 32 this moments.The described disconnection confining force that helps the counter-force of inhaling shell fragment 2 to reduce magnetic latching relay 1, make magnetic latching relay 1 close retaining force and disconnect the confining force balance, be the sealing voltage and the off voltage balance of magnetic latching relay 1, improve the electric property of magnetic latching relay.

With helping suction shell fragment 2 to be arranged on the line of motion of driving member 3, be a kind of the simplest, and effective method.Its derivative form can for shown in Fig. 4 a, 4b, the stiff end of will help inhaling shell fragment 2a inserts driving member 3a.

As Fig. 4 a, for magnetic latching relay in closed operating state, it helps inhales shell fragment 2a and is in freedom, state does not by compression help and inhales shell fragment 2a and do not contact with driving member 3a, helps this moment suction shell fragment 2a not work.

As Fig. 4 b, for magnetic latching relay when disconnecting operating state, be subjected to the extruding of driving member 3a, help that to inhale shell fragment 2a compression stressed, help and inhale shell fragment 2a and have counter-force to act on driving member 3a at this moment.Be a kind of embodiment of the present utility model equally.

And for example Fig. 5 a, 5b are a kind of derivative forms that has of the present utility model.Can replace above-mentioned helping with helical spring 2b and inhale shell fragment 2.

As Fig. 5 a, for magnetic latching relay in closed operating state, its helical spring 2b is in freedom, state by compression not, helical spring 2b does not contact with driving member 3b, this moment, helical spring 2b did not work.

As Fig. 5 b, for magnetic latching relay when disconnecting operating state, be subjected to the extruding of driving member 3b, helical spring 2b compression is stressed, helical spring 2b has counter-force to act on impeller 3b at this moment.Be another embodiment of the present utility model.

More than, use a kind of typical magnetic latching relay structure, described the utility model and helped the structure of inhaling shell fragment, the utility model helped inhale the shell fragment effective optimization counter-force of magnetic latching relay cooperate, improved the electric property of magnetic latching relay.Help the position of inhaling shell fragment, the utility model to help the suction shell fragment to go for any single-phase magnetic latching relay as long as set, be used for improving its counter-force and cooperate, and the utility model helps the suction shell fragment also can be useful for two-phase, three-phase and heterogeneous magnetic latching relay.Or, change for example dish-shaped shell fragment, bridge-type shell fragment, U font shell fragment etc. to helping the shape of inhaling shell fragment.These above-mentioned application are that the structural design personnel can realize by simple transformation, also in description scope of the present utility model.
