Abstract
A magnetic latching relay with anti-magnetic-inference capacity comprises a case, an electromagnetic coil, an actuator, a pushing piece, a spring piece, a fixed terminal and a movable terminal. The pushing piece extends perpendicularly along the direction of a right side plate of the case. The spring piece extends perpendicularly along the direction of a top plate of the case. The right end portion of the pushing piece is hinged with the upper end portion of the spring piece. The fixed terminal is fixedly arranged outside the right side plate of the case. The movable terminal opposite to the fixed terminal is arranged on the lower end portion of the spring piece. The electromagnetic coil is arranged close to a left side plate in the case and the axis of the electromagnetic coil is perpendicular to a bottom plate in the case. The actuator is arranged close to the right side of the electromagnetic coil and a pushing rod of the actuator extends along the direction perpendicular to the top plate of the case. The upper end of the pushing piece is hinged with the left end of the pushing rod. The magnetic latching relay can effectively improve the anti-magnetic-inference capacity.
Description
Technical field
The utility model relates to a kind of magnetic latching relay with diamagnetic interference performance.
Background technology
Magnetic latching relay is a kind of new type of relay that grew up in recent years, also is a kind of automatic switch.The same with other electromagnetic relays, circuit is played automatic connection and cutting action.Different is, the normally closed or normally open of magnetic latching relay is the effect that relies on permanent-magnet steel fully, and the conversion of its on off state is to lean on the pulse electrical signal of certain width to trigger and accomplish.
See also Fig. 1, actuator 3 along continuous straight runs are installed in the housing 5, and are positioned at the top of solenoid 2; So; Distance C between the end face of this actuator 3 and housing 5 only has 10.5 millimeter, and then under the effect than high-intensity magnetic field such as 400mT magnet, original closed contact will be disconnected; Obviously, the present diamagnetic interference performance extreme difference of magnetic latching relay.
The utility model content
To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of magnetic latching relay with stronger diamagnetic interference performance.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of magnetic latching relay with diamagnetic interference performance; Comprise housing, solenoid, actuator, pushing piece, shell fragment, fixed terminal and movable terminal; Pushing piece is along the direction vertical extent of the right plate of housing, and shell fragment is along the direction vertical extent of housing top board, and the right part of pushing piece and the upper end of shell fragment are hinged; This fixed terminal is fixed at outside the right plate of housing; This movable terminal is installed in the bottom of shell fragment and relative with this fixed terminal, and this solenoid vicinity is installed in the left plate in the housing, and the base plate of the axis normal of solenoid in housing; This actuator is near the right side that is installed in this solenoid; And the catch bar of actuator extends along the top board direction of vertical shell, and the upper end of pushing piece and the left end of catch bar are hinged, and the distance between the catch bar of actuator and the right plate of housing is 19 millimeters.
Distance between the catch bar of actuator and the left plate of housing is 21 millimeters.
Above-mentioned magnetic latching relay with diamagnetic interference performance can effectively improve the diamagnetic interference performance of this magnetic latching relay through solenoid and actuator being stood on end on the base plate that places housing to enlarge the distance between actuator and the housing.
Description of drawings
Fig. 1 is the structural representation of existing magnetic latching relay.
Fig. 2 is the structural representation of the preferred embodiments of the utility model magnetic latching relay.
Embodiment
To combine accompanying drawing and embodiment below, the utility model done further describing:
See also Fig. 2, the utility model relates to a kind of magnetic latching relay with diamagnetic interference performance, and its preferred embodiments comprises housing 25, solenoid 22, actuator 23, pushing piece 4, shell fragment 7, fixed terminal 6 and movable terminal 8.
These solenoid 22 contiguous left plates that are installed in the housing 25; And the base plate of the axis normal of this solenoid 22 in housing 25; This actuator 23 is near the right side that is installed in this solenoid 22, and the catch bar 235 of actuator 23 extends along the top board direction of vertical shell 25, and the left end of the upper end of pushing piece 4 and catch bar 235 is hinged; And pushing piece 4 extends along the direction of the right plate in the vertical shell 25; The upper end of the right-hand member of pushing piece 4 and shell fragment 7 is hinged, and movable terminal 7 is installed in the bottom of this shell fragment 7 and relative with this fixed terminal 6, and fixed terminal 6 is fixed at outside the right plate of housing 25.In the present embodiment, between the catch bar 235 of actuator 23 and the left plate of housing 25 is 21 millimeters apart from B, and the distance A between the catch bar 235 of actuator 23 and the right plate of housing 25 is 19 millimeters, to improve the diamagnetic interference performance of this magnetic latching relay.
During use, solenoid 22 energising makes the direction motion of turning right of the catch bar 235 of actuator 23, spurring this pushing piece 4, thereby promotes this shell fragment 7, so that this movable terminal 8 up moves, is close to this fixed terminal 6 of contact until this movable terminal 8.
Above-mentioned magnetic latching relay with diamagnetic interference performance can effectively improve the diamagnetic interference performance of this magnetic latching relay through solenoid and actuator being stood on end on the base plate that places housing to enlarge the distance between actuator and the housing.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection range of the utility model claim all according to the technical scheme and the design of above description.
