Detailed Description
Specific embodiments of the present utility model are described in further detail below. It should be understood that the description herein of the embodiments of the utility model is not intended to limit the scope of the utility model.
Fig. 1 to 6 are schematic structural views of a push-pull magnetic latching relay according to the present utility model. The push-pull type magnetic latching relay comprises a base 10, an electromagnetic unit 20 arranged in the base 10, a movable spring assembly 30 arranged in the base 10, and a connecting assembly 40 connecting the electromagnetic unit 20 and the movable spring assembly 30. It is conceivable that the push-pull magnetic latching relay further includes other functional structures, such as connection terminals, etc., which are known to those skilled in the art, and will not be described herein.
The base 10 includes a base body 11, and an electromagnetic mounting portion 12 and a moving spring mounting portion 13 are provided in the base body 11. The electromagnetic mounting portion 12 is used for disposing the electromagnetic unit 20, and the moving spring mounting portion 13 is used for disposing the moving spring assembly 30. A partition plate 14 is disposed between the electromagnetic mounting portion 12 and the moving spring mounting portion 13, and the partition plate 14 can avoid mutual interference between the electromagnetic unit 20 and the moving spring assembly 30, and plays an auxiliary mounting role on the electromagnetic unit 20.
The electromagnetic unit 20 includes a yoke 21 provided in the electromagnetic mounting portion 12, an electromagnetic bracket 22 provided in the electromagnetic mounting portion 12 with an end face thereof abutting against the yoke 21, a magnetic steel bracket 23 vertically provided in the electromagnetic bracket 22, an electromagnet 24 provided in the magnetic steel bracket 23 away from an open end of the electromagnetic bracket 22, and a push-pull member 25 provided on an end of the magnetic steel bracket 23 facing away from the bottom of the base 10.
The yoke 21 is disposed on the partition plate 14, and the yoke 21 has a knife edge higher than the partition plate 14, so as to be assembled with the connection assembly 40. The function of the yoke 21 should be well known to those skilled in the art and will not be described in detail herein.
The electromagnetic stand 22 includes a support 221 provided on the base body 11, and a top plate 222 connected to both ends of the opening of the support 221. Two clamping blocks 223 are respectively arranged on the two side end surfaces of the electromagnetic bracket 22.
The magnetic steel bracket 23 comprises a magnetic steel sleeve 231 connected with two ends of the electromagnetic bracket 22, and a clamping groove 232 arranged on the middle area of the outer side wall of the magnetic steel sleeve 231. The clamping groove 232 is clamped with the clamping block 223. One electromagnet 24 is disposed on one end of the magnetic steel sleeve 231 away from the opening of the electromagnetic bracket 22, and one end of the electromagnet 24 is embedded in the electromagnetic bracket 22.
The push-pull assembly 25 includes a magnetic steel 251 disposed in the magnetic steel sleeve 231, and a push-pull rod 252 connected to an end of the magnetic steel 251 opposite to the electromagnet 24. The other end of the push-pull rod 252 is provided with a bayonet 253. The catch 253 mates with the connection assembly 40.
The outer side wall of the push-pull rod 252 is sleeved with a top supporting seat 254, the top supporting seat 254 is made of a metal material capable of being adsorbed by magnetic force, and the outer diameter size of the top supporting seat 254 is smaller than or equal to the inner diameter size of the magnetic steel sleeve 231. The abutment 254 is used to limit the movement range of the magnetic steel 251, so as to prevent the push-pull rod 252 from moving excessively. A gasket 255 is disposed between the abutment 254 and the magnetic steel 251, the gasket 255 is made of a flexible material, and the gasket 255 is used for preventing the magnetic steel 251 from directly colliding with the abutment 254.
The movable spring assembly 30 includes a pair of fixed springs 31 provided in the movable spring mounting portion 13, and a movable spring 32 abutting against the fixed springs 31, one end of the fixed springs 31 extending to the outside of the base body 11 for connection with an external device. The static reed 31 is powered on when it collides with the movable reed 32, and is powered off when it does not collide.
The connecting assembly 40 includes an armature 41 that is clamped to the edge of the yoke 21 and has one end clamped to the push-pull rod 252, a plastic member 42 that is disposed on the other end of the armature 41, and a connecting member 43 that connects the plastic member 42 to the movable spring 32.
Referring to fig. 5, the armature 41 is L-shaped. The armature 41 is provided with a pair of connection ports 411, and the width of the connection ports 411 is larger than the thickness of the yoke 21. The end of the armature 41, which is close to the push-pull rod 252, is provided with a clamping groove 412, and the clamping groove 41 is connected with the push-pull rod 252. The connecting piece 43 connects the movable contact spring 32 with the connecting assembly 40.
When in use, the electromagnet 24 and the magnetic steel 251 are attracted or repelled by changing the anode and cathode of the electromagnet 24, so that the magnetic steel 251 moves in the magnetic steel sleeve 231. When the magnetic steel 251 abuts against the supporting seat 254, the magnetic steel can be attracted to the supporting seat 254 by its own magnetism, and the electromagnet 24 does not need to be electrified for a long time. The magnetic steel 251 drives the push-pull rod 252 connected with the magnetic steel sleeve 231 to move. When the push-pull rod 252 moves axially, the armature 41 is driven to rotate by a small extent along the connection part of the armature and the yoke 21. The movable spring 32 connected with the armature 41 is driven to approach or separate from the fixed spring 31. And, since the supporting base 254 and the electromagnet 24 are made of metal materials that can be attracted by magnetic force, after the electromagnet 24 is powered off, the magnetic steel 251 can be attracted to the portion that contacts with the magnetic steel by the magnetic force of itself, so as to keep the relay on or off.
Compared with the prior art, the push-pull type magnetic latching relay provided by the utility model has the advantages that the coil and the sliding plate in the transmission magnetic latching relay are replaced by the magnetic steel bracket 23, the electromagnet 24 and the push-pull assembly 25. And the L-shaped armature 41 is matched with the push-pull rod 252, so that the connection or disconnection of the movable reed 32 and the static reed 31 can be controlled in a manner of changing the angle of the armature 41, the structure is more compact, the use of winding coils is reduced, and the production cost is reduced.
The above is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model, and any modifications, equivalent substitutions or improvements within the spirit of the present utility model are intended to be covered by the claims of the present utility model.
