A contactor 100 according to an embodiment of the present invention is described below with reference to fig. 1-8.

As shown in fig. 1 and 2, a contactor 100 according to an embodiment of the present invention includes: a stationary contact piece 21, a movable contact piece 22 and a driving mechanism 30.

The driving mechanism 30 includes a driving portion 301 and a driven portion 302, the driven portion 302 is connected to the movable contact 22, and the driving portion 301 is used for driving the driven portion 302 to rotate so as to make the movable contact 22 contact with or separate from the stationary contact 21.

It can be understood that when the contactor 100 controls the contact or separation of the movable contact 22 and the stationary contact 21, the driving portion 301 drives the driven portion 302 to rotate, and then the driven portion 302 drives the movable contact 22 to rotate so as to make the movable contact 22 and the stationary contact 21 contact or separate.

In this way, the movable contact piece 22 can be contacted with or separated from the static contact piece 21 in a rotating manner, so that the movable space required by the movement of the movable contact piece 22 is reduced, the size of the contactor 100 is reduced, the miniaturized design of the contactor 100 is facilitated, and the force required by the movement of the movable contact piece 22 is smaller, so that the power-on time of the contactor 100 is reduced, the waste of electric energy is reduced, and the temperature rise of the contactor 100 is reduced.

The "connection between the driven portion 302 and the movable contact 22" includes direct connection between the driven portion 302 and the movable contact 22, indirect connection between the driven portion 302 and the movable contact 22, or connection that can realize movement of the driven portion 302 and the movable contact 22, which is not limited herein.

According to the contactor of the embodiment of the invention, the driving part 301 can drive the driven part 302 to rotate so as to enable the movable contact piece 22 to be contacted with or separated from the static contact piece 21, namely, the movable contact piece 22 is contacted with or separated from the static contact piece 21 in a rotating manner, so that the movable space required by the movement of the movable contact piece 22 is reduced, the size of the contactor 100 is reduced, the miniaturization design of the contactor 100 is facilitated, the force required by the movement of the movable contact piece 22 is small, the energizing time of the contactor 100 is reduced, and the waste of electric energy and the temperature rise of the contactor 100 are reduced.

In some embodiments, the contactor 100 further comprises: a support 10 and a tension member 61.

The driven portion 302 is rotatably mounted at the rotation fulcrum a of the mount 10; the movable contact piece 22 and the tension piece 61 are respectively connected with the driven part 302, and the movable contact piece 22 and the tension piece 61 are respectively positioned at two sides of the rotation pivot A; wherein the tension member 61 is adapted to apply a force to separate the movable contact piece 22 from the stationary contact piece 21 when the movable contact piece 22 is in contact with the stationary contact piece 21.

It can be understood that since the movable contact piece 22 (the end of the movable contact piece 22 that is not in contact with or separated from the stationary contact piece 21, i.e., the left end of the movable contact piece 22 in fig. 2) and the tension piece 61 are located on both sides of the rotation fulcrum a, respectively, the movable contact piece 22 can rotate with the rotation fulcrum a as the rotation center.

Thus, the movable contact piece 22 can rotate by utilizing the lever principle, so that the required attraction force is smaller when the movable contact piece 22 is attracted with the static contact piece 21, the energizing time of the contactor 100 is reduced, and the waste of electric energy and the temperature rise of the contactor 100 are reduced.

Further, the tension member 61 is adapted to apply a force to separate the movable contact piece 22 from the stationary contact piece 21 when the movable contact piece 22 is in contact with the stationary contact piece 21.

Therefore, by providing the tension member 61, when the movable contact piece 22 is separated from the static contact piece 21, the tension member 61 can apply the force separating from the static contact piece 21 to the movable contact piece 22, so that the movable contact piece 22 is separated from the static contact piece 21 more quickly, and after the movable contact piece 22 is separated from the static contact piece 21, the separated state of the movable contact piece 22 and the static contact piece 21 can be maintained by the force of the tension member 61, so that continuous power-on is not needed to maintain the separated state of the movable contact piece 22 and the static contact piece 21, and the power-on time is further reduced, so that the energy consumption and the temperature rise of the contactor 100 are reduced.

Wherein the tension member 61 applies a force to separate the movable contact piece 22 from the stationary contact piece 21, including but not limited to a tensile force, a pushing force, a repulsive force, an elastic force, a magnetic force, etc.

As shown in fig. 1 and 2, for example, the contactor 100 includes a support 10, a movable contact piece 22, a stationary contact piece 21, and a driving mechanism 30.

For example, an installation space is formed in the support 10, the driving mechanism 30 is suitable for being installed in the installation space, the contact pieces are provided with a plurality of groups, each group of contact pieces comprises a static contact piece 21 and a movable contact piece 22, the static contact piece 21 and the movable contact piece 22 can be respectively electrically connected with the electrical components, when the contactor 100 is electrified, the driving mechanism 30 drives the movable contact piece 22 and the static contact piece 21 to be contacted or separated, the connection or disconnection of two electrical components can be realized, the movable contact piece 22 and the static contact piece 21 of each group of contact pieces can be used for realizing the connection or disconnection of one circuit, and thus, the connection or disconnection of a plurality of circuits can be realized by a plurality of groups of contact pieces.

In the related art, when the contactor 100 is used to conduct a plurality of circuits, a plurality of contactors 100 are required to be combined, and thus, too many parts are attached, and the volume of the contactor 100 is increased, which results in a waste of space.

In the invention, by arranging a plurality of groups of contact pieces, the connection or disconnection of a plurality of loops can be realized, and the plurality of groups of contact pieces share the driving mechanism 30, so that the structure of the contactor 100 is simplified, the parts of the contactor 100 are reduced, the volume of the contactor 100 is reduced, and the miniaturized design of the contactor 100 is facilitated.

In some embodiments, as shown in fig. 5, the distance from the movable contact piece 22 (the end of the movable contact piece 22 that is in contact with or separated from the stationary contact piece 21) to the rotation fulcrum a is greater than the distance from the tension member 61 to the rotation fulcrum a.

Therefore, the force arm between the tension member 61 and the rotation pivot point a is shorter, and the force arm from the end of the movable contact piece 22 contacting or separating from the static contact piece 21 to the rotation pivot point a is longer, so that when the tension member 61 applies the force separating from the static contact piece 21 to the movable contact piece 22, the movable contact piece 22 can be driven to keep separating from the static contact piece 21 by using the short force arm to pry the driven part 302. In this way, the tension member 61 can be made more labor-saving.

In some embodiments, as shown in fig. 5, the tension member 61 is an elastic member, a first end of the tension member 61 (e.g., an upper end of the tension member 61 in fig. 5) is connected to the driven portion 302, and a second end of the tension member 61 (e.g., a lower end of the tension member 61 in fig. 5) is connected to the support.

Thus, by attaching the second end of the tension member 61 (e.g., the lower end of the tension member 61 in fig. 5) to the holder to fix the tension member 61 to the holder 10, the structural stability of the tension member 61 is enhanced, and by configuring the tension member as an elastic member, which may be a spring or other elastic structure, the structure thereof is simpler, the cost is easily reduced, and it is convenient to maintain the separated state (e.g., the state shown in fig. 5) of the movable contact piece 22 and the stationary contact piece 21 by the elastic force of the elastic member.

It should be noted that, when the driving portion 301 drives the driven portion 302 to drive the movable contact piece 22 to release from the static contact piece 21, the movement of the movable contact piece 22 overcomes the elastic force, i.e. the direction opposite to the elastic force, so that after the contactor 100 is powered off, the movable contact piece 22 is automatically separated from the static contact piece 21 under the action of the elastic force. The elastic force is the characteristic of the elastic piece, so that the elastic piece can be used for multiple times, and the use cost is reduced.

In some embodiments, as shown in fig. 5, the contactor 100 further comprises: the limiting fixing frame 71, the limiting fixing frame 71 is connected to the support, and the limiting fixing frame 71 is provided with an upper limiting portion 711 and a lower limiting portion 712, and the driven portion 302 and the first end of the tension member 61 are connected between the upper limiting portion 711 and the lower limiting portion 712.

Therefore, the upper limit part 711 and the lower limit part 712 are arranged, so that the connection part of the driven part 302 and the first end of the tension member 61 is protected through the upper limit part 711 and the lower limit part 712, the possibility that the connection part of the driven part 302 and the first end of the tension member 61 is subjected to external impact is reduced, the connection part of the driven part 302 and the first end of the tension member 61 is protected, and the connection stability of the connection part of the driven part 302 and the first end of the tension member 61, namely the connection stability of the driven part 302 and the first end of the tension member 61, is enhanced.

In some embodiments, as shown in fig. 5 and 6, the movable contact 22 includes a fixing portion 2201 and a connecting portion 2202, where the fixing portion 2201 is fixedly mounted to the support 10, and the connecting portion 2202 is connected to a first end (a right end as viewed in fig. 6) of the driven portion 302 and is adapted to be driven by the driven portion 302 to rotate relative to the fixing portion 2201.

Thus, when the driven portion 302 drives the connecting portion 2202 to rotate corresponding to the fixing portion 2201, contact or separation between the movable contact piece 22 and the static contact piece 21 can be achieved, so that when the movement of the movable contact piece 22 is controlled, the whole movable contact piece 22 is not required to be controlled to rotate, namely, the fixing portion 2201 is not moved, at the moment, only a part of the connecting portion 2202 of the movable contact piece 22 is required to be controlled to rotate, so that contact or separation between the movable contact piece 22 and the static contact piece 21 can be achieved, and thus, the force required when the movable contact piece moves can be reduced, and the power-on time of the contactor 100 is reduced, so that waste of electric energy is reduced.

Wherein, fixed part 2201 and connecting part 2202 can be integrated into one piece structure, are convenient for reduce the production degree of difficulty and reduce production process.

In some embodiments, the connection 2202 is configured as a flexible conductive element.

Therefore, by configuring the connecting portion 2202 as a flexible conductive member, the connecting portion 2202 and the fixing portion 2201 are prevented from being broken when the driven portion 302 drives the connecting portion 2202 to move relative to the fixing portion 2201, and the difficulty in movement of the connecting portion 2202 is reduced.

In some embodiments, as shown in fig. 5, at least a portion of the connecting portion 2202 is configured as an arcuate structure 2203, the arcuate structure 2203 protruding away from the driven portion 302.

Therefore, by arranging the arch-shaped structure 2203, the arch-shaped structure 2203 protrudes towards the direction away from the driven part 302, so that the problem of stress concentration at the connecting part 2202 when the driven part 302 drives the connecting part 2202 to move is avoided, and the service life of the movable contact piece 22 is prolonged.

Illustratively, as shown in fig. 5 and 7, one of the holder 10 and the driven portion 302 is provided with a fitting groove 51 and the other is provided with a fitting projection 12, the fitting projection 12 being inserted into the fitting groove 51.

The connection between the mating protrusion and the mating groove is formed as a rotation fulcrum a.

For example, the support 10 is provided with the fitting groove 51, the driven part 302 is provided with the fitting protrusion 12, or the support 10 is provided with the fitting protrusion 12, and the driven part 302 is provided with the fitting groove 51, so that the armature 50 can be better rotatably connected with the support 10 by providing the fitting groove 51 and the fitting protrusion 12, thereby enhancing the connection stability of the two and being beneficial to enhancing the movement stability of the driven part 302.

In some embodiments, as shown in fig. 7, the stationary contact 21 is provided with a first stationary contact 211, the movable contact 22 is provided with a first end 221 and a second end 222, the first end 221 is provided with a first movable contact 2211, the second end 222 is provided with a second stationary contact, and the driving portion 301 is used for driving the driven portion 302 to move the first end 221 so as to make the first movable contact 2211 contact with or separate from the first stationary contact 211.

It will be appreciated that in actual use of the contactor 100, the stationary contact 21 and the movable contact 22 are used to electrically connect with electrical components, for example, one electrical component may be electrically connected with one end of the stationary contact 21 where the first stationary contact 211 is not provided, and another electrical component may be electrically connected with the second stationary contact of the movable contact 22. In this way, when the driving portion 301 drives the driven portion 302 to drive the movable contact piece 22 to contact or separate from the stationary contact piece 21, contact or separation between the first movable contact 2211 and the first stationary contact 211, that is, electrical connection or disconnection between the first stationary contact 211 and the second stationary contact, can be achieved, and electrical connection or disconnection between two electrical components can be achieved.

It should be noted that, in the contactor 100 of the related art, two stationary contacts and two movable contacts are generally provided, and the two movable contacts and the two stationary contacts are used for controlling one circuit, so that multiple circuits are used in combination, which causes more parts to be attached to the contactor, and thus the contactor 100 is excessively large and has high cost.

In the present invention, the first movable contact 2211 and the second movable contact are welded on the movable contact 22, which is equivalent to integrating the first movable contact 2211 and the second movable contact on the movable contact 22, so that a structure of one movable contact can be saved, that is, one loop can be controlled by two movable contact first movable contacts 211 and second movable contacts and one movable contact first movable contact 2211, and the number of accessory parts can be reduced when the multi-loop is used, thereby being beneficial to reducing the volume of the contactor 100 and the production cost thereof.

In some embodiments, the first movable contact 2211 and the first stationary contact 211 are both configured as planar contacts, so that the contact effect of the first movable contact 2211 and the first stationary contact 211 is better, on one hand, the overcurrent capability can be increased, and on the other hand, the temperature rise of the contactor 100 is facilitated to be reduced.

In some implementations, as shown in fig. 5, the contactor 100 further includes: a first mounting bracket 72.

The first mounting bracket 72 is provided with a connecting piece 722, and the first end of the driven portion 302 (the right end of the driven portion 302 as shown in fig. 5) and the movable contact piece 22 are both fixed to the connecting piece 722, so that the movable contact piece 22 is driven to contact with or separate from the stationary contact piece 21 when the first end of the driven portion 302 rotates.

Thus, by providing the connection piece so that the first end of the driven portion 302 (the right end of the driven portion 302 as shown in fig. 5) and the movable contact piece 22 are indirectly connected, wherein the connection piece may be an insulating structure to function as an insulation between the first end of the driven portion 302 (the right end of the driven portion 302 as shown in fig. 5) and the movable contact piece 22 and to facilitate enhancement of connection stability between the first end of the driven portion 302 (the right end of the driven portion 302 as shown in fig. 5) and the movable contact piece 22.

The first end of the driven portion 302 (the right end of the driven portion 302 as shown in fig. 5) and the movable contact 22 may be connected to the connecting piece 722 by a clamping, or a bolting, or a clamping manner, which is not limited herein.

In some implementations, the first mounting bracket 72 is further provided with a first mounting cavity 721, at least a portion of the movable contact piece 22 is located in the first mounting cavity 721, and the reset member 62 is mounted in the first mounting cavity 721, the reset member 62 is disposed at the first end of the driven portion 302, and the reset member 62 is adapted to apply a force to keep the movable contact piece 22 separated from the stationary contact piece 21 when the movable contact piece 22 is separated from the stationary contact piece 21.

Therefore, by providing the first mounting cavity 721 and disposing the reset element 62 in the first mounting cavity 721, the reset element 62 is not directly visible, so as to facilitate the function of protecting the reset element 62, and the reset element 62 can apply a force keeping separation with the static contact piece 21 to the dynamic contact piece 22 when the dynamic contact piece 22 is separated from the static contact piece 21.

In this way, when the movable contact piece 22 is separated from the static contact piece 21, the restoring piece 62 can apply the force separating from the static contact piece 21 to the movable contact piece 22, so that the movable contact piece 22 is separated from the static contact piece 21 faster, and after the movable contact piece 22 is separated from the static contact piece 21, the separated state of the movable contact piece 22 and the static contact piece 21 can be kept by the force of the restoring piece 62, so that continuous power is not needed to keep the separated state of the movable contact piece 22 and the static contact piece 21, and the power-on time is further reduced, so that the energy consumption and the temperature rise of the contactor 100 are reduced.

Wherein the restoring member 62 may be configured as an elastic member, and the restoring member 62 applies a force to the movable contact piece 22 to separate from the stationary contact piece 21, including but not limited to a tensile force, a pushing force, a repulsive force, an elastic force, a magnetic force, etc.

In some implementations, the contactor 100 further includes: the second mounting bracket 73, the second mounting bracket 73 is mounted on the support 10, and a second mounting cavity 731 is formed in the second mounting bracket 73, and at least a portion of the stationary contact 21 is located in the second mounting cavity 731 to be in contact with or separated from the movable contact 22.

Therefore, by arranging the second mounting bracket 73, at least part of the static contact piece 21 is located in the second mounting cavity 731 to be in contact with or separated from the moving contact piece 22, so that a certain limiting effect can be achieved on the movement of the moving contact piece 22 through the inner wall of the second mounting cavity 731, thereby avoiding the overlarge movement amplitude of the moving contact piece 22 and being beneficial to reducing the volume of the contactor 100.

Meanwhile, the second mounting cavity 731 of the second mounting bracket 73 can protect the contact position of the movable contact piece 22 and the static contact piece 21 to a certain extent, so as to avoid the influence of water or dust and the like on the contact of the movable contact piece 22 and the static contact piece 21.

In some implementations, the driving portion 301 is configured as an electromagnetic driver, and the driven portion 302 is configured as the armature 50, for applying a first magnetic force to the armature 50 to bring the armature 50 into contact with or out of contact with the movable contact piece 22 and the stationary contact piece 21.

Therefore, the moving contact piece 22 can be driven to move by the armature 50, so as to avoid the first magnetic force acting on the moving contact piece 22 directly, thereby being beneficial to reducing the influence on the moving contact piece 22, and the moving contact pieces 22 of a plurality of groups of contact pieces can be arranged on the armature 50, so that the moving contact pieces 22 of a plurality of groups of contact pieces can be simultaneously driven by the armature 50 to contact or separate from the corresponding static contact pieces 21.

In some embodiments, the contactor 100 further comprises: a holder 40.

The holder 40 is adapted to apply a force to the movable contact piece 22 to be in contact with the stationary contact piece 21 when the movable contact piece 22 is in contact with the stationary contact piece 21, and to apply a force to be separated from the stationary contact piece 21 to the movable contact piece 22 when the movable contact piece 22 is separated from the stationary contact piece 21.

Accordingly, after the driving mechanism 30 drives the movable contact piece 22 and the stationary contact piece 21 to contact or separate, the contact or separation of the movable contact piece 22 and the stationary contact piece 21 can be maintained by the holder 40, so that the contactor 100 does not need to be continuously energized, so that the energy consumption and the temperature rise of the contactor 100 can be reduced.

For example, the holder 40 may be installed in the holder to function as a protection holder 40 using the holder 10, and the holder 40 is used to apply a force to the movable contact piece 22 to contact the stationary contact piece 21 when the movable contact piece 22 contacts the stationary contact piece 21, or to apply a force to the movable contact piece 22 to separate from the stationary contact piece 21 when the movable contact piece 22 separates from the stationary contact piece 21. In this way, when the movable contact piece 22 and the static contact piece 21 are contacted or separated, even if the contactor 100 is powered off, that is, the contactor 100 does not need to be continuously powered on, the retainer 40 can be used for retaining the contact of the movable contact piece 22 and the static contact piece 21 so as to reduce the energy consumption and the temperature rise of the contactor 100, or the retainer 40 can be used for retaining the separation of the movable contact piece 22 and the static contact piece 21 so as to avoid the problem that the contactor 100 is subjected to vibration impact and false contact occurs, thereby being beneficial to enhancing the stability of the contactor 100.

In the related art, the contactor needs to be continuously energized while the movable contact piece and the static contact piece are kept continuously attracted, which leads to an increase in energy consumption of the contactor and an increase in temperature of the contactor.

In the present invention, by providing the holder 40, the contact or separation between the movable contact piece 22 and the stationary contact piece 21 can be maintained by the holder 40, so that the contactor 100 does not need to be continuously energized, so that the energy consumption and the temperature rise of the contactor 100 can be reduced.

In some embodiments, the driving portion 301 is configured as an electromagnetic driving member, and the driven portion 302 is configured as the armature 50, and the electromagnetic driving member is configured to apply a first magnetic force to the armature 50 to cause the armature 50 to bring the movable contact piece 22 into contact with or separate from the stationary contact piece 21. Wherein the holding member 40 is configured as a magnetic member 41, and the magnetic member 41 is adapted to apply a second magnetic force to the armature 50 in the same direction as the first magnetic force.

Therefore, the moving contact piece 22 can be driven to move by the armature 50, so as to avoid the first magnetic force acting on the moving contact piece 22 directly, which is beneficial to reducing the influence on the moving contact piece 22, and the moving contact pieces 22 of multiple groups of contact pieces can be arranged on the armature 50, so that the moving contact pieces 22 of multiple groups of contact pieces can be simultaneously driven by the armature 50 to contact or separate from the corresponding static contact pieces 21, and the second magnetic force of the magnetic piece 41 can be used for keeping the contact or separation of the moving contact piece 22 and the static contact pieces 21. In this way, the effect of maintaining the contact or separation of the movable contact piece 22 and the stationary contact piece 21 can be achieved without the movement of the magnetic member 41 and without the magnetic member 41 directly contacting the movable contact piece 22 or the stationary contact piece 21.

For example, the electromagnetic driving member includes a low-voltage coil 31, the low-voltage coil 31 is installed in the installation space, the low-voltage coil 31 is sleeved outside the iron core 32, and the low-voltage coil 31 is located below the armature 50, wherein the low-voltage coil 31 is provided with a low-voltage terminal 311, the low-voltage coil 31 can be electrically connected with the outside through the low-voltage terminal 311 to realize the energizing of the low-voltage coil 31, when the low-voltage coil 31 is energized with currents in different directions, the low-voltage coil 31 can generate magnetic fields, the iron core 32 is magnetized by the magnetic fields to generate currents, the currents conduct corresponding magnetic forces to generate a first magnetic force on the armature 50, the first magnetic force can be downward forward attraction force when the low-voltage coil 31 is energized with positive currents, and the first magnetic force can be upward reverse repulsive force when the low-voltage coil 31 is energized with negative currents.

When the first magnetic force is a downward forward attractive force, the armature 50 drives the movable contact piece 22 to move downward so as to make the movable contact piece 22 contact with the static contact piece 21, and at this time, the second magnetic force is also a downward forward attractive force, so that when the low-voltage coil 31 is powered off, the contact between the movable contact piece 22 and the static contact piece 21 can be maintained by the second magnetic force.

Or when the first magnetic force is an upward reverse repulsive force, the armature 50 drives the movable contact piece 22 to move upward to separate the movable contact piece 22 from the static contact piece 21, and at this time, the second magnetic force is also an upward reverse repulsive force, so that when the low-voltage coil 31 is powered off, the separation of the movable contact piece 22 and the static contact piece 21 can be maintained by the second magnetic force.

Thus, when the movable contact piece 22 and the stationary contact piece 21 are contacted or separated, the contact or separation of the movable contact piece 22 and the stationary contact piece 21 can be maintained by the second magnetic force, so that the low-voltage coil 31 does not need to be continuously energized, so that the energy consumption and the temperature rise of the contactor 100 can be reduced.

It should be noted that, the magnetic member 41 may be configured to have a magnetic structure, and two magnetic members 41 may be provided, and directions of magnetic forces of the two magnetic members 41 are opposite. For example, when the electromagnetic driving member applies a first magnetic force to the armature 50 to bring the armature 50 into contact with the movable contact piece 22 and the stationary contact piece 21, one magnetic member 41 applies a second magnetic force to the movable contact piece 22 to keep the movable contact piece 22 in contact with the stationary contact piece 21, and when the electromagnetic driving member applies a first magnetic force to the armature 50 to bring the armature 50 into separation with the movable contact piece 22 and the stationary contact piece 21, the other magnetic member 41 applies a second magnetic force to the movable contact piece 22 to keep the movable contact piece 22 separated from the stationary contact piece 21.

Alternatively, the magnetic member 41 may be configured as a magnetization structure that is magnetized by a first magnetic force when the electromagnetic driving member applies the first magnetic force to the armature 50 so that the magnetization structure has a second magnetic force.

In some embodiments, the magnetic member 41 is adapted to generate a second magnetic force when the electromagnetic drive is energized and to maintain the second magnetic force when the electromagnetic drive is de-energized.

Thereby, the magnetic member 41 is allowed to be magnetized by the magnetic field of the electromagnetic driving member to generate the second magnetic force, so that the magnetic member 41 can make full use of the magnetic field generated by the electromagnetic driving member, and the magnetic member 41 can still maintain the second magnetic force when the electromagnetic driving member is powered off to maintain the contact or separation of the movable contact piece 22 and the stationary contact piece 21 by the second magnetic force. In this way, the electromagnetic drive need not be continuously energized, so as to reduce the power consumption and temperature rise of the contactor 100.

In some embodiments, the electromagnetic driving member is fixedly mounted to the support 10, and the magnetic member 41 is attached to the electromagnetic driving member.

From this, can strengthen the structural stability of electromagnetic drive spare, and magnetic part 41 links to each other with the laminating of electromagnetic drive spare, on the one hand for the arrangement of magnetic part 41 and electromagnetic drive spare is compacter, in order to reduce occupation to installation space, on the other hand, is convenient for when the circular telegram of electromagnetic drive spare produces the magnetic field, and magnetic part 41 can be magnetized by electromagnetic drive spare more soon in order to form the second magnetic force.

As shown in fig. 5 and 7, the support 10 is provided with a mounting frame 11, the electromagnetic driving member is mounted on the mounting frame 11, and the magnetic member 41 is fixedly sleeved on the mounting frame 11.

From this, through setting up mounting bracket 11 for the electromagnetic drive spare can install on support 10 more steadily, with the structural stability of reinforcing electromagnetic drive spare, and the mounting bracket 11 is located to the cover of magnetic part 41, can strengthen the structural stability of magnetic part 41, avoids magnetic part 41 and electromagnetic drive spare to break away from.
