Description
Technical field
The utility model is related to a kind of magnetic latching relay, and more particularly to one kind can realize the pinpoint magnetic of magnetic circuit
Guard relay.
Background technology
The structure of existing magnetic latching relay is made up of magnetic circuit part, contact portion, pushing mechanism and base.Magnetic circuit part
Typically it is made up of the magnetic circuit of two almost symmetries, including static magnetic conduction body component (i.e. yoke and iron core), movable magnetic conduction body component
(i.e. armature) and coil (i.e. bobbin and enamel-covered wire), contact portion include dynamic spring part, quiet spring part, pushing mechanism typically by
Pushing block is taken on, and pushing mechanism is connected between movable magnetic conduction body component and dynamic spring part.Magnetic circuit part is magnetic latching relay
Induction mechanism, magnetic latching relay coil leads to direct impulse voltage, and magnetic circuit part work, pushing block promotes the dynamic of contact portion
Spring part makes dynamic and static contact, the actuating of relay, and keeps "on" position；Coil leads to reverse impulse voltage, the magnetic circuit part division of labor
Make, the dynamic spring part of pushing block promotion contact portion disconnects dynamic and static contact, relay involution, and keeps state of operating a switch.
Magnetic latching relay main application fields are electric-power metering, and major function is switch and measures.Due to magnetic keep after
Electric appliance load electric current is big (5A~200A), is electrified for a long time caloric value big, it is desirable to which magnetic latching relay can be reliable in closing operation
Contact portion remains reliable contacts, conducting after action, closing operation, the reliable disjunction of energy when operating of operating a switch, after operation of operating a switch
Contact portion remains off state.
The high magnetic latching relay product of reliability is developed, in addition to magnetic circuit part parameter reasonable in design, must also
Magnetic circuit part must be designed and be assembled to the precise positioning structure after base, to ensure that magnetic circuit part is assembled to the essence of the perpendicularity after base
Degree meets design requirement, when magnetic circuit part works not by extraneous vibration impact or own rotation inertia influenceed and be subjected to displacement,
Tilt etc..
The design of existing magnetic latching relay it is main using elastic conjunction, epoxy resin glue sticking mode come to magnetic circuit part
Positioned.The bobbin of magnetic circuit part is generally arranged on base using horizontal mode, is mainly used and has been filled during installation
Bobbin together, yoke are engaged with base, one side of the yoke of magnetic circuit part bobbin end position with passing through
The iron core of bobbin through hole is mutually fixed, and the another side of the yoke of magnetic circuit part is then engaged with armature, in the installation of magnetic circuit part
The positive negative direction of X-axis (i.e. with the horizontal direction of the axis perpendicular of bobbin through hole) at place, is to increase location structure on base
That is locating slot clamps the yoke in magnetic circuit part, i.e., clamp the another side of yoke using locating slot is set on base, due to
Base is formed using plastic production, and different degrees of inclination occurs in plastics location structure after plastic mould injection moulding,
Cause magnetic circuit part assemble after perpendicularity it is bad, directly affect the functional reliability of magnetic circuit part.And use epoxy resin gluing
Connect, then glue easily pollutes the working position of magnetic circuit part, while reducing production efficiency.Y-axis in the installation place of magnetic circuit part is positive and negative
Direction (i.e. with the axis identical horizontal direction of bobbin through hole), magnetic circuit part passes through profile and the corresponding part (phase of base
When in the width of base) coordinate the positioning for realizing Y-axis.The installation place of magnetic circuit part Z axis negative direction (i.e. and bobbin
The vertical direction of the axis perpendicular of through hole), contacted using the big face of magnetic circuit part with the big face of base and realize positioning.Magnetic circuit part
Loaf includes the bottom face of bobbin two ends (i.e. corresponding to the two ends of through hole), the bottom faces of two bobbins be for bottom
The fitting surface that seat coordinates, due to reasons such as bobbin injecting forming pressure inequality, contraction distortions, it is difficult to ensure that the two ends of bobbin
Bottom face it is non-warping, flatness precision is often beyond more than 0.2mm (different depending on part dimension)；And four supports on base
In face (being inner surface), two of which supporting surface is used for supporting the bottom face at bobbin two ends, and two other supporting surface is used for branch
Support fits in the bottom face of the another side of the yoke at bobbin two ends, because bobbin and base are made of plastics, due to line
The reason such as coil and base injecting forming pressure inequality, contraction distortion, it is difficult to ensure that aforementioned four supporting surface and bobbin
The bottom face at two ends is non-warping, and flatness precision is more than more than 0.3mm (different depending on part dimension).The supporting surface and magnetic circuit of base
The flatness precision that the fitting surface of bobbin in part is caused in part forming is bad, can all cause after magnetic circuit part assembling
Perpendicularity is bad, has a strong impact on the assembly precision of energized relay circuit part, causes properties of product bad.
