Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment protection, in particular to a dual-power forced tripping type leakage protector. Background Art

[0002] When leakage fault occurs in the equipment or when protection is needed for people who are at risk of electric shock, leakage protector can disconnect the main line in time, thus it is widely used. The application technology of leakage protector is very mature. From the protection principle, there are voltage type and current type. From the mechanical structure, there are self-locking type and pull-in type. The leakage protector of mechanical self-locking structure type of current or voltage is usually used. The biggest feature of the mechanical self-locking structure is that when the power supply of the leakage protector in operation is interrupted or the power supply circuit is missing a phase or the line contact is poor, the mechanical self-locking structure of the leakage protector in the closed state will not be able to actively open the closed contacts. At this time, if the power supply circuit is abnormally missing a phase and the ground wire is abnormally energized or leaking, the leakage protector will lose its protective function, resulting in a safety accident; therefore, the application of the suction type is increasing, which can ensure the safety of electricity use; however, the design and use scenarios of the existing leakage protector equipment can only perform leakage protection on a single load, and cannot perform leakage protection on two loads separately; in response to the above problems, a new leakage protector is designed in the present invention that can perform leakage protection on two loads separately at the same time, especially when it is suitable for products such as electric water heaters, it can perform leakage protection on two electric heating tubes separately at the same time.

[0003] The electric control method used in existing dual-power electrical appliances is to achieve micro-disconnection of the circuit through a relay, but due to the relatively small opening distance, the safety is low. Therefore, a dual-power leakage protector device that can achieve a safe 3mm opening distance is needed to replace the above structure. Summary of the invention

[0004] In view of the above-mentioned defects in the prior art, the present invention provides a dual-power forced-tripping leakage protector to solve the problem that the existing leakage protector cannot provide effective and safe leakage protection for dual loads respectively.

[0005] In order to solve the above technical problems, the present invention provides a dual-power forced tripping type leakage protector, comprising: a protector base plate, a spring, two protector devices arranged in parallel on the upper part of the protector base plate, and a wiring terminal arranged and fixed on the protector base plate, wherein the protector device controls the opening and closing of the dual-power forced tripping type leakage protector;

[0006] The protector device includes a circuit breaker, a connection device, and a locking device. The locking device is arranged between the circuit breaker and the connection device, and the locking device is used to control the disconnection and closing of the spring and the wiring terminal.

[0008] The spring sheet pressing block is provided with a buckle, a vertical fork groove and a side pressure rod, and the buckle is used to cooperate with the lock buckle;

The shaft sleeve rotating driving block on the spring piece pressing block cooperates with the shaft sleeve rotating abutment block, and the spring piece pressing block can drive the synchronous pressing block to rotate synchronously through the cooperation between the shaft sleeve rotating driving block and the shaft sleeve rotating abutment block.

[0011] When the power is turned on, at least one protector device is energized, and the connecting iron core drives the spring piece pressing block to rotate through the vertical fork groove, so that the side pressure rod at the bottom of the spring piece pressing block presses the spring piece downward, and the pressing of the spring piece pressing block can drive the synchronous pressing block to rotate synchronously so that the synchronous pressure rod presses the spring piece downward at the same time, and the buckle rotates to a position abutting against the lock buckle and locks the fixed circuit breaker iron core, so that the spring piece pressing block remains in a pressed state, and the spring piece and the wiring terminal remain in a connected state, and the buffering effect of the buffer cap is used to eliminate the vibration when the locking device is closed, thereby achieving circuit connection;

[0012] When the power is disconnected, the circuit breaker device drives the locking lever to rotate through the cross groove, so that the buckle and the lock are separated and released, and the spring is disconnected from the terminal due to the loss of downward pressure, thereby achieving circuit disconnection;

[0013] By adopting the above technical solution, the dual-power leakage protector can simultaneously provide leakage protection for dual loads, and the overall structure is simple, which can effectively save costs, reduce the overall volume of the leakage protector, and make the protection effect stable and reliable.

DETAILED DESCRIPTION

[0043] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0044] Embodiment 1:

[0045] A dual-power forced tripping type leakage protector according to an embodiment of the present invention, such as Figures 1 to 11As shown, it includes: a protector base plate 2, a spring 4, two protector devices 1 arranged in parallel on the upper part of the protector base plate 2, and a wiring terminal arranged on the lower part of the protector base plate 2. In this embodiment, the wiring terminal is set as a pin 3, and the pin 3 can be directly inserted into the socket. In other use environments, a wire can be led out from the wiring terminal for electrical connection. The protector device 1 controls the disconnection and closing of the dual-power forced tripping type leakage protector;

[0046] Each protector device 1 includes a circuit breaker 5, a connecting device 6, and a locking device 7. The locking device 7 is arranged between the circuit breaker 5 and the connecting device 6. The locking device 7 is used to control the disconnection and closing of the spring 4 and the pin 3.

[0047] The locking device 7 includes a spring pressing block 26 and a locking lever 27, on which a lock buckle 33, a cross fork groove 34 and a buffer cap seat 35 are provided; Fig.13 As shown, the spring piece pressing block 26 is provided with a buckle 36, a vertical fork groove 37 and a side pressure rod 38, the buckle 36 is used to cooperate with the lock buckle 33, the buffer cap seat 35 is arranged above the lock buckle 33, and the buffer cap seat 35 is provided with a buffer cap 51 for buffering, and the buffer cap 51 made of silicone material is arranged on the locking lever 27, and the upper part of the locking lever 27 is the control circuit part of the leakage protector. Therefore, if there is no buffer cap 51, the vibration generated by the closing of the leakage protector during operation will be transmitted to the control circuit above the leakage protector of this embodiment, which greatly shortens the working life of the leakage protector and affects the working stability of the leakage protector.

[0048] The connecting device 6 is provided with a connecting iron core 23 extending laterally, and the connecting iron core 23 is engaged with the vertical fork groove 37. The connecting device 6 also includes a connecting coil 24 and a connecting spring 25. The connecting coil 24 is fixed inside the connecting device 6, and the connecting spring 25 and the connecting iron core 23 are horizontally arranged in the inner cavity of the connecting coil 24; the circuit breaker device 5 also includes a circuit breaker coil and a circuit breaker spring. The circuit breaker coil is fixed inside the circuit breaker device 5, and the circuit breaker spring and the circuit breaker iron core 21 are vertically fixed in the inner cavity of the circuit breaker coil; one end of the circuit breaker iron core 21 is in contact with the circuit breaker spring, and the other end of the circuit breaker iron core 21 is used to engage with the horizontal fork groove 34;

[0049] A synchronous pressure block 8 is provided between the spring piece pressure blocks 26 of the two protector devices 1 arranged in parallel, and the two spring piece pressure blocks 26 rotate coaxially with the synchronous pressure blocks 8. A synchronous pressure rod 39 is provided at the bottom of the synchronous pressure block 8, and shaft sleeve rotation abutment blocks 53 are provided on both sides of the synchronous pressure block 8. The shaft sleeve rotation drive block 52 on the spring piece pressure block 26 cooperates with the shaft sleeve rotation abutment block 53, and the spring piece pressure block 26 can drive the synchronous pressure block 8 to rotate synchronously through the cooperation of the shaft sleeve rotation drive block 52 and the shaft sleeve rotation abutment block 53. In this embodiment, the spring piece pressure block 26 is movably hinged with the first support 30 set in the middle position of the protector bottom plate 2 through the first pin shaft 28, and the two protector devices The two spring piece pressing blocks 26 of 1 and the synchronous pressing block 8 between the two spring piece pressing blocks 26 are jointly arranged on the first pin shaft 28 and can rotate around the first pin shaft 28. The spring piece pressing block 26 can be driven to rotate by the connecting iron core 23, and the synchronous pressing block 8 is rotated under the drive of the spring piece pressing block 26, that is, when the sleeve rotating driving block 52 rotates with the spring piece pressing block 26, the sleeve rotating driving block 52 located on the rotating sleeve of the spring piece pressing block 26 and the sleeve rotating abutting block 53 located on the rotating sleeve of the synchronous pressing block 8 are abutted and matched, so that when the side pressure rod 38 at the bottom of the spring piece pressing block 26 presses down the corresponding spring piece, the synchronous pressure rod 39 presses down the corresponding spring piece at the same time;

[0050] When the power is turned on, at least one protector device 1 is energized, and the connecting iron core 23 drives the spring piece pressing block 26 to rotate through the vertical fork groove 37, so that the side pressure rod 38 located at the bottom of the spring piece pressing block 26 presses the spring piece 4 downward, and the pressing of the spring piece pressing block 26 can drive the synchronous pressing block 8 to rotate synchronously so that the synchronous pressure rod 39 is pressed downward at the same time, and the buckle 36 rotates to a position abutting against the lock buckle 33 and locks the fixed circuit breaker iron core 21, so that the spring piece pressing block 26 remains in a pressed state, and the spring piece 4 remains in a connected state with the terminal, and the buffering effect of the buffer cap 51 is used to eliminate the vibration when the locking device 7 is closed, thereby achieving circuit connection;

[0051] When the power is disconnected, the energy storage capacitor discharges to the circuit breaker coil, and the magnetic field generated by the circuit breaker coil causes the circuit breaker core 21 of the circuit breaker device 5 to move downward. Therefore, through the snap-fit ​​relationship between the circuit breaker core 21 and the cross fork groove 34, when the circuit breaker core 21 moves downward, it also drives the cross fork groove 34 to move downward, thereby driving the locking lever 27 to rotate, so that the buckle 36 is separated from the lock buckle 33 and disengaged, and at the same time, the spring piece 4 is disconnected from the terminal due to the loss of downward pressure, thereby realizing circuit disconnection. Through the above structure, this embodiment achieves the problem that the spring piece 4 and the terminal of the dual-power leakage protector can achieve a safe 3mm opening distance, and through the provision of the synchronous pressure block 8, it saves costs and simplifies the connection device.

[0052] like Fig.14As shown, in the present embodiment, the shaft sleeve rotation driving block 52 and the shaft sleeve rotation abutment block 53 are both open shaft sleeves, and when the shaft sleeve rotation driving block 52 and the shaft sleeve rotation abutment block 53 cooperate, there is a reserved rotation space between the shaft sleeve rotation driving block 52 and the shaft sleeve rotation abutment block 53, that is, when the power is turned on, the connecting iron core 23 drives the spring piece pressing block 26 to rotate through the vertical fork groove 37. At the same time, through the cooperation and abutment between the upper part of the shaft sleeve rotation driving block 52 and the upper part of the shaft sleeve rotation abutment block 53, the synchronous pressing block 8 rotates at the same time to achieve the compression of the spring piece 4. When the power is disconnected, the locking lever 27 is released, and the spring piece pressing block 26 is no longer pressed down and rotates. In this process, since there is a reserved rotation space between the shaft sleeve rotation driving block 52 and the shaft sleeve rotation abutment block 53, that is, there is a certain gap between the lower part of the shaft sleeve rotation driving block 52 and the lower part of the shaft sleeve rotation abutment block 53, the synchronous pressing block 8 can lag behind the rotation of the spring piece pressing block 26.

[0053] The spring clip 4 includes a first spring clip 11, a second spring clip 12, a third spring clip 13 and a PE line spring clip 14, which pass through the bottom of the circuit breaker 5 and are clamped and fixed by the protector bottom plate 2 and the circuit breaker 5, and the pin 3 includes a second pin 15, a first pin 16, a ground pin 17 and an auxiliary connecting pin 20, the auxiliary connecting pin 20 is electrically connected to the first pin 16, the first pin 16 is connected to the live wire, and the second pin 15 is connected to the neutral wire;

[0054] The second pin 15, the first pin 16, the ground pin 17 and the auxiliary connecting pin 20 are provided with an electrical connection contact 18 at the top, and the first spring sheet 11, the second spring sheet 12, the third spring sheet 13 and the PE line spring sheet 14 are provided with spring sheet contacts 19 corresponding to the electrical connection contact 18 at the ends. The one side pressure rod 38 can be used to press down the first spring sheet 11 to connect with the first pin 16, and the other side pressure rod 38 can be used to press down the third spring sheet 13 to connect with the auxiliary connecting pin 20. The synchronous pressure rod 39 can be used to press down the second spring sheet 12 to connect with the second pin 15, and can also press down the PE line spring sheet 14 at the same time. The E-line spring piece 14 is connected to the ground pin 17. Further, in the specific implementation process, when only one of the protector devices 1 is powered on, only the spring piece pressing block 26 corresponding to the protector device 1 remains in a depressed state, that is, the first spring piece 11 is connected to the first pin 16, or the third spring piece 13 is connected to the auxiliary connecting pin 20. Since the auxiliary connecting pin 20 is electrically connected to the first pin 16, and as long as one spring piece pressing block 26 remains in a depressed state, it will also drive the synchronous pressing block 8 to remain in a depressed state, that is, the second spring piece 12 is connected to the second pin 15, P The E-wire spring piece 14 is connected to the ground wire pin 17, so when any protector device 1 is powered on, it can ensure that the leakage protector is in the power-on state and plays a protective role. When the two protector devices 1 are powered on at the same time, the two loads in the circuit can be protected from leakage at the same time, which is the dual-power leakage protector of this embodiment. For further application of this embodiment, for example, when the dual-power leakage protector of this embodiment is applied to a water heater, the two electric heating tubes can be controlled respectively at the same time to heat the water storage and the water outlet of the water heater. Specifically, the water heater An internal water storage tank and an external water outlet tank are provided, and each is provided with an electric heating pipe for heating. The two protector devices 1 respectively perform leakage protection on the two electric heating pipes. The internal water storage tank is heated to about 40°C by the electric heating pipe for insulation. When hot water is needed, the external water outlet tank can also be quickly heated to about 75°C. The above scheme can achieve better insulation effect and slower heat dissipation. Compared with insulation at a higher temperature, it has better energy-saving effect. At the same time, the two electric heating pipes can be protected from leakage by the leakage protector of this embodiment.
