Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The first embodiment is as follows:
referring to fig. 1 and 2, an electrical short-circuit prevention connector includes a first member 3 and a second member 4 electrically coupled to each other.
Referring to fig. 2, 3 and 4, the first part 3 comprises a housing 11, the housing 11 being provided with at least one set of separate wiring elements 6 and connecting elements 5, the connecting elements 5 being adapted to be electrically connected to the second part 4 when the first part 3 is mated with the second part 4. When the first component 3 is mated with the second component 4, the connecting element 5 makes electrical contact with the wiring element 6.
In particular, the housing 11 is provided with two separate sets of wiring elements 6 and connecting elements 5, the two wiring elements 6 being in communication with the live and neutral conductors, respectively, and the two wiring elements 6 being intended to be in electrical contact with different connecting elements 5. When the first member 3 is separated from the second member 4, the wiring members 6 and the connecting members 5 in the two groups are separated from each other.
Alternatively, referring to fig. 2 and 9, the housing 11 is provided with a plurality of separated wiring elements 6 and connecting elements 5, and a conducting strip 16, wherein when the wiring elements 6 are communicated with the live wire, the conducting strip 16 is communicated with the neutral wire; when the wiring connection element 6 is in communication with the neutral conductor, the conductive strip 16 is in communication with the live conductor. The conductive plate 16 extends through the housing 11 and is used for electrical connection of the second part 4 when the first part 3 is mated with the second part 4.
The housing 11 is also provided with a grounding element 15 connected to the ground, the grounding element 15 being connected to the second part 4 for protecting the second part 4 when the first part 3 is mated with the second part 4 to drain the leakage current of the second part 4 to the ground.
Since the connecting element 5 is used for electrically connecting with the second part 4, the connecting element 5 is generally exposed outside the first part 3, when the first part 3 is sprayed with water, the connecting element 5 is easy to stick water, and the two connecting elements 5 or the connecting element 5 and the conductive sheet 16 may be conducted. When the first part 3 is separated from the second part 4, the wiring element 6 is separated from the connecting element 5, the connecting element 5 is disconnected from the high-voltage power supply, and even if the connecting element 5 is wet, the high-voltage power supply can not be short-circuited, so that fire is prevented from being caused.
When the first member 3 is separated from the second member 4, one of the connecting member 5 and the wiring member 6 is separated from the other in the direction of separation of the first member 3 and the second member 4, so that the connecting member 5 and the wiring member 6 are forcibly fitted when the first member 3 is subsequently fitted to the second member 4.
When the first part 3 is separated from the second part 4, the connecting element 5 and the wiring element 6 have two automatic separation modes.
Referring to fig. 2 and 4, in the first automatic separation mode of the connection member 5 from the terminal member 6, the connection member 5 and the terminal member 6 are normally in an electrical contact state when they are not subjected to an external force. Between the first part 3 and the second part 4 a drive 7 is arranged, i.e. the drive 7 is located on the first part 3 or the second part 4. When the first part 3 is separated from the second part 4, the driver 7 drives the connecting element 5 to deform or displace, so that the connecting element 5 is separated from the wiring element 6.
When the driving member 7 is located on the second component 4, the driving member 7 is a hook integrally formed on the second component 4, and when the first component 3 is separated from the second component 4, the hook pulls the connecting element 5 to displace or deform, so that the connecting element 5 is separated from the wiring element 6.
Referring to fig. 5 and 6, when the driving member 7 is located on the first component 3, the driving member 7 includes a sliding member 71 slidably connected to the housing 11, and a spring 72 disposed on the housing 11 for driving the sliding member 71 to slide. The sliding piece 71 is a sliding rod or a sliding block, the spring 72 is in a compressed or stretched state, and the spring 72 drives the sliding piece 71 to abut against the connecting element 5 by means of elastic force recovery, so that the connecting element 5 deforms or displaces, and the connecting element 5 is separated from the wiring element 6.
Alternatively, the sliding member 71 is integrally formed with the connecting member 5, and the connecting member 71 is deformed or displaced with the sliding member 71, so that the connecting member 5 and the wire connecting member 6 are separated.
Preferably, the housing 11 comprises a housing body 111, a hollow column 112 disposed on the housing body 111, the sliding rod and the spring 72 are both mounted in the hollow column 112, and the spring 72 drives the sliding rod to slide along the hollow column 112 and abut on the connecting element 5, so that the connecting element 5 is separated from the wiring element 6. The hollow column 112 can increase the sliding stroke of the sliding rod, so that the sliding stroke of the sliding rod is not limited by the size of the shell 111, and the larger the sliding stroke is, the larger the distance between the connecting element 5 and the wiring element 6 is, and the better the power-off effect is.
The connecting element 5 is fixed on the housing 11, and the connecting element 5 is deformed by the force applied by the driving part 7, so that the connecting element 5 is separated from the wiring element 6. The connecting element 5 is structurally stable and is not easily detached from the housing 11.
The connecting element 5 has a fastening point 8 which is fixedly connected to the housing 11, a contact point 9 for making electrical contact with the connecting element 6, and a force application point 10 for applying a force to the drive element 7, the force application point 10 being located between the fastening point 8 and the contact point 9. The further the point of application 10 is from the fastening point 8, the more easily the connecting element 5 is deformed when the driver 7 applies a force to the point of application 10. When the point of application 10 is located between the fixing point 8 and the contact point 9, the connecting element 5 can be deformed to some extent without coming into direct contact with the contact point 9, so as to avoid affecting the electrical contact of the subsequent contact point 9 with the terminal element 6.
Specifically, the distance between the fixed point 8 and the contact point 9 is L1, the distance between the force application point 10 and the contact point 9 is L2, and L2/L1= 0.25-0.75, so that the force application point 10 remains at a distance from both the fixed point 8 and the force application point 10 with the contact point 9. The connecting element 5 is not only capable of being deformed to a greater extent so that the connecting element 5 is stably separated from the terminal element 6, but also the force exerted by the drive 7 on the point of application 10 does not interfere with the fixing of the fixing point 8 and the electrical contact of the subsequent contact point 9 with the terminal element 6.
Alternatively, the connecting element 5 can be slidably connected to the housing 11, the connecting element 5 is block-shaped, and the driving member 7 abuts to drive the connecting element 5 to slide, so that the connecting element 5 is separated from the wiring element 6.
In addition, the driving member 7 can drive the wiring element 6 to deform or displace, so that the connecting element 5 is separated from the wiring element 6; alternatively, the two driving members 7 drive the connecting member 5 and the wire connecting member 6, respectively, so that the connecting member 5 and the wire connecting member 6 are separated from each other.
Specifically, the housing 11 is provided with a mounting groove recessed on one side thereof, the wiring member 6 and the connection member 5 are mounted in the mounting groove, and the connection member 5 penetrates the housing 11 from the side of the housing 11 where the mounting groove is formed, and is used for electrical connection with the second member 4 on the other side of the housing 11. When the first part 3 is mated with the second part 4, the second part 4 can only be in electrical contact with the connecting element 5 and be in electrical conduction with the wiring element 6 through the connecting element 5. When the connecting element 5 is separated from the wiring element 6 and other conductive elements are contacted with the connecting element 5, the electricity cannot be conducted, so that the potential safety hazard in the non-working state is reduced.
In the second automatic separation mode of the connection member 5 and the terminal member 6, referring to fig. 2 and 10, the connection member 5 and the terminal member 6 are normally in a separated state when they are not subjected to an external force. At least one of the connecting element 5 and the wiring element 6 is a restoring piece 12, and when the first part 3 is separated from the second part 4, the restoring piece 12 is spontaneously deformed, so that the connecting element 5 is separated from the wiring element 6, instead of driving the connecting element 5 to be separated from the wiring element 6 by the driving piece 7.
The connecting element 5 is a restoring member 12; alternatively, the wiring member 6 is the recovery member 12; alternatively, both the connecting element 5 and the restoring element are restoring members 12. Because the restoring piece 12 is used for realizing the separation of the connecting element 5 and the wiring element 6 by means of spontaneous deformation, the separation structure is simple, the cost is low, and the use is convenient.
The restoring member 12 is spontaneously deformed by its own elasticity, and the connecting member 5 and the terminal member 6 are restored to the electrically contacted state;
or, the restoring member 12 is a bimetal which deforms spontaneously according to temperature, the first member 3 and the second member 4 are electrically coupled to generate heat energy, when the first member 3 and the second member 4 are separated, the heat energy is not generated, the temperature of the bimetal is reduced, the bimetal deforms spontaneously, and the connecting element 5 and the wiring element 6 are restored to the separated state.
Example two:
the technical feature of this embodiment that is different from the first embodiment is that, referring to fig. 2, when the first member 3 is mated with the second member 4, the connecting element 5 has three electrical contact ways with the wiring member 6, and the three electrical contact ways of the connecting element 5 and the wiring member 6 in this embodiment can be arbitrarily combined with the two separation ways of the connecting element 5 and the wiring member 6 in the first embodiment.
In the first electrical contact between the connecting element 5 and the connecting element 6, the connecting element 6 and the connecting element 5 overcome the driving force of the drive 7 by means of the second part 4, and the connecting element 5 and the connecting element 6 can be electrically contacted relatively easily.
Referring to fig. 2 and 3 and 4, the connecting element 5 is separated from the connecting element 6 by the driving force of the driving member 7, and when the first and second parts 3 and 4 are closed, the second part 4 directly abuts against the driving member 7, and the driving member 7 is separated from the connecting element 5. When the first part 3 is mated with the second part 4, the connecting element 5 and the wiring element 6 are not acted by the driving force of the driving piece 7 and do not tend to separate from each other, and the connecting element 5 and the wiring element 6 can be electrically contacted more easily.
The connecting element 5 is an elastic piece; alternatively, the connecting member 5 and the wiring member 6 are both elastic members. When the first part 3 is separated from the second part 4, the elastic member receives the driving force of the driving member 7, and the elastic member is elastically deformed so that the connection member 5 and the wire connection member 6 are separated from each other. When the first part 3 is mated with the second part 4, the driving force of the driver 7 is overcome by the second part 4, and the connecting element 5 is elastically restored to be deformed and electrically connected with the wiring element 6.
Specifically, referring to fig. 2, 5 and 6, when the first component 3 is mated with the second component 4, the second component 4 applies a force to the slider 71 and pushes the slider 71 away from the connecting element 5, the force applied to the connecting element 5 disappears, and the connecting element 5 elastically recovers and makes electrical contact with the wiring element 6.
When the first part 3 is separated from the second part 4, the driving part 7 can automatically disconnect the wiring element 6 from the connecting element 5, and after the first part 3 is matched with the second part 4, the connecting element 5 is automatically electrically contacted with the wiring element 6, so that the use is convenient, and the manual contact of the connecting element 5 or the wiring element 6 is not needed, so that the electric shock of a user is avoided.
Alternatively, the wire connecting member 6 is separated from the connecting member 5 by the driving force of the driving member 7, and the wire connecting member 6 is an elastic member and can be elastically restored.
When the first part 3 is mated with the second part 4, the connecting element 5 is simultaneously subjected to the driving force of the driving member 7 and the force of the second part 4, and the force of the second part 4 not only overcomes the driving force of the driving member 7, but also brings the connecting element 5 into electrical contact with the wiring element 6.
Alternatively, when the first part 3 is mated with the second part 4, the wiring element 6 is simultaneously subjected to the driving force of the driving member 7 and the force of the second part 4, and the force of the second part 4 not only overcomes the driving force of the driving member 7, but also brings the wiring element 6 into electrical contact with the connecting element 5.
Referring to fig. 2 and 10, in the second electrical contact manner of the connection element 5 and the wiring member 6, when the first member 3 is mated with the second member 4, the connection element 5 is deformed or displaced by the pressure of the second member 4, so that the connection element 5 and the wiring member 6 are electrically contacted; alternatively, when the first member 3 is mated with the second member 4, the wiring member 6 is deformed or displaced by the pressure of the second member 4, so that the connection member 5 and the wiring member 6 are electrically contacted. The second component 4 applies pressure to enable the connecting element 5 to be in electrical contact with the wiring element 6, other structures do not need to be additionally arranged between the first component 3 and the second component 4, the structure is simple, and the cost is low.
Referring to fig. 2 and 11, the wiring connection element 6 and the connection element 5 may also be electrically contacted by means of magnetic force when the first component 3 is mated with the second component 4. The connecting element is provided with a magnet, the second component is provided with magnetism, when the first component 3 is matched with the second component 4, the second component 4 attracts the connecting element 6 with the magnet to be close, so that the connecting element 6 is deformed or displaced under the action of the magnetic force of the second component 4, and the wiring element 6 is in electric contact with the connecting element 5;
alternatively, when the first member 3 is mated with the second member 4, the wiring member 6 is deformed or displaced by the magnetic force of the second member 4, and the wiring member 6 and the connection member 5 are electrically contacted.
Referring to fig. 2 and 12, in a third electrical contact mode between the connecting element 5 and the wire connecting element 6, a sensing member 13 and an electric actuator 14 electrically connected with the sensing member are arranged between the first component 3 and the second component 4. The sensing element 13 is a contact sensor located on the first part 3, and the electric element 14 is a micro cylinder. When the first component 3 is mated with the second component 4, the contact sensor senses the pressure of the second component 4 and sends an electrical signal to the microcylinder, and the power output shaft of the microcylinder extends out to drive one of the connecting element 5 and the wiring element 6 to displace or deform, so that the connecting element 5 and the wiring element 6 are in electrical contact.
Example three:
a household appliance is a water boiler, a health preserving kettle or a soybean milk machine.
Referring to fig. 13, the household appliance includes a housing 1 and a base 2, wherein the housing 1 is a heating container for containing and heating liquid. The top of the frame 2 is provided with a first part 3 and the bottom of the machine body 1 is provided with a second part 4, the second part 4 being coupled with the first part 3 under the action of gravity when the machine body 1 is placed on the frame 2. At this moment, the cooperation of first part 3 and second part 4 can rely on the action of gravity of organism 1 itself completely for organism 1 does not take place the separation with frame 2, need not artificial application of force and makes both cooperations, and is comparatively laborsaving.
