Description

Technical Field

[0001] The present invention belongs to the technical field of electric power equipment, and in particular relates to a connector for a switch solenoid valve and a control method for the switch solenoid valve. Background Art

[0002] Switch solenoid valves are widely used. For example, in the hydraulic control system of the controllable pitch propeller system, the switch solenoid valve is used to control the on and off of the oil circuit to which it is connected. In order to reduce the control complexity of the hydraulic control system, the selected switch solenoid valve generally has only one control signal input. For example, when the power is turned on, the switch solenoid valve is turned on.

[0003] After the switch solenoid valve is installed, there is only one control signal for the switch solenoid valve, and the control room that sends the control signal to control the switch solenoid valve is generally far away from the switch solenoid valve. If the solenoid valve needs to be operated, such as maintenance and debugging, the on-site maintenance personnel cannot directly control the switch solenoid valve through the control room. Therefore, the on-site maintenance personnel need to manually hold the valve core of the switch solenoid valve to control the switch solenoid valve, which makes the operation extremely inconvenient. Summary of the invention

[0004] The disclosed embodiment provides a connector for a switch solenoid valve and a control method for a switch solenoid valve, which can be connected to the switch solenoid valve to control the valve core movement of the switch solenoid valve during maintenance and debugging of the switch solenoid valve, so as to improve the maintenance convenience of the switch solenoid valve. The technical solution is as follows:

[0005] An embodiment of the present disclosure provides a connector for a switch solenoid valve, the connector comprising a shell and a toggle switch, wherein a first portion of the toggle switch is located inside the shell, a second portion of the toggle switch is located outside the shell, and the toggle switch is movably connected to the shell to switch between a first state and a second state; when the toggle switch is in the first state, the toggle switch is electrically connected to the power supply and the switch solenoid valve, respectively, to form a closed loop; when the toggle switch is in the second state, the power supply is disconnected from the switch solenoid valve, and the toggle switch is connected in series in a control circuit of the switch solenoid valve.

[0006] In another implementation of the present disclosure, the toggle switch includes a first fixed terminal, a second fixed terminal and a movable terminal, the first fixed terminal and the second fixed terminal are located in the housing and connected to the housing, the first fixed terminal is used to be electrically connected to the power supply, and the second fixed terminal is used to be electrically connected to the control circuit of the switch solenoid valve; the movable terminal is partially located in the housing and movably located between the first fixed terminal and the second fixed terminal, and the movable terminal is electrically connected to the switch solenoid valve; when the toggle switch is in the first state, the movable terminal is electrically connected to the first fixed terminal, and when the toggle switch is in the second state, the movable terminal is electrically connected to the second fixed terminal.

[0007] In another implementation of the present disclosure, the first fixed terminal and the second fixed terminal are both U-shaped structural members, and the first fixed terminal has a first opening, the second fixed terminal has a second opening, the first opening and the second opening are arranged opposite to each other, and when the toggle switch is in the first state, the movable terminal is located in the first opening and contacts with the first fixed terminal; when the toggle switch is in the second state, the movable terminal is located in the second opening and contacts with the second fixed terminal.

[0008] In another implementation of the present disclosure, the first fixed terminal and the second fixed terminal have the same structure, and both include a first contact head, a second contact head and a connecting arm, the first contact head and the second contact head are respectively connected to the two ends of the connecting arm, and define a U-shaped structure with the connecting arm, the first contact head and the second contact head are conductors, and the middle part of the connecting arm is at least partially an insulator; the movable terminal includes an operating member, a third contact head and a fourth contact head, the third contact head and the fourth contact head are respectively connected to the two sides of the operating member, and are located in the housing, the third contact head and the fourth contact head are both electrically connected to the switch solenoid valve, the third contact head is used to be electrically connected to the first contact head, and the fourth contact head is used to be electrically connected to the second contact head.

[0009] In yet another implementation of the present disclosure, the first contact head, the second contact head, the third contact head, and the fourth contact head are all copper sheets.

[0010] In another implementation of the present disclosure, the connector further includes a control switch, which is connected to the housing; the control switch is connected in series between the power supply and the toggle switch, and is used to control the on / off connection between the toggle switch and the power supply.

[0011] In yet another implementation of the present disclosure, the control switch is a press control switch.

[0012] In yet another implementation of the present disclosure, the power supply is integrated into the housing.

[0013] In another implementation of the present disclosure, a control method for a switch solenoid valve is also provided. Based on the connector described above, the control method includes: controlling the toggle switch of the connector to be in a first state, so that the toggle switch is electrically connected to the power supply and the switch solenoid valve, respectively, to form a closed loop; controlling the on and off of the closed loop and the current in the closed loop to debug or repair the switch solenoid valve.

[0014] In another implementation of the present disclosure, the control method further includes: after the debugging or maintenance of the switch solenoid valve is completed, controlling the toggle switch to be in a second state so that the switch solenoid valve is connected in series with the control circuit of the toggle switch.

[0016] The technical solution provided by the embodiments of the present disclosure brings the following beneficial effects:

[0017] When the switch solenoid valve is inspected or debugged, the connector provided by the embodiment of the present disclosure may be arranged at the switch solenoid valve.

[0018] Since the connector includes a housing and a toggle switch, and the first part of the toggle switch is located inside the housing and the second part of the toggle switch is located outside the housing, the housing can provide a mounting base for the toggle switch and protect the toggle switch at the same time.

[0019] Since the toggle switch is movably connected to the housing, and the toggle switch is freely switched between the first state and the second state. When the toggle switch is in the first state, the toggle switch forms a closed loop with the power supply and the switch solenoid valve respectively. When the toggle switch is in the second state, the toggle switch is disconnected from the power supply and is connected in series with the switch solenoid valve. Therefore, when debugging the switch solenoid valve, the toggle switch can be controlled so that the toggle switch is in the first state. At this time, the toggle switch forms a closed loop with the power supply and the switch solenoid valve, and the power supply can provide power to the switch solenoid valve, so that the valve core of the toggle switch can be actuated, thereby realizing maintenance or debugging.

[0020] When the switch solenoid valve is inspected or debugged, the toggle switch can be controlled to be in the second state, so that the switch solenoid valve and the power supply are disconnected. At this time, the switch solenoid valve is independent of the connector, and the switch solenoid valve can be directly controlled to operate.

[0021] It can be seen that when the switch solenoid valve is inspected or debugged, the valve core position can be controlled through the above connector to avoid manual operation and improve operating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0038] Figure 1 A schematic diagram of the structure of a connector for switching a solenoid valve provided in an embodiment of the present disclosure, such as Figure 1 As shown, an embodiment of the present disclosure provides a connector for switching a solenoid valve.

[0039] The joint includes a housing 1 and a toggle switch 2, wherein a first portion of the toggle switch 2 is located inside the housing 1, a second portion of the toggle switch 2 is located outside the housing 1, and the first portion and the second portion of the toggle switch 2 are connected. The toggle switch 2 is movably connected to the housing 1 to switch between a first state and a second state.

[0040] When the toggle switch 2 is in the first state, the toggle switch 2 is electrically connected to the power supply 100 and the switch solenoid valve 101 respectively to form a closed loop.

[0041] When the toggle switch 2 is in the second state, the power supply 100 is disconnected from the switch solenoid valve 101 , and the toggle switch 2 is connected in series in the control circuit of the switch solenoid valve 101 .

[0042] When the switch solenoid valve is inspected or debugged, the connector provided by the embodiment of the present disclosure may be arranged at the switch solenoid valve.

[0043] Since the joint includes the housing 1 and the toggle switch 2, and the first part of the toggle switch 2 is located inside the housing 1, and the second part of the toggle switch 2 is located outside the housing 1, the housing 1 can provide an installation base for the toggle switch 2, and the housing 1 can protect the toggle switch 2.

[0044] Since the toggle switch 2 is movably connected to the housing 1, and the toggle switch 2 is freely switched between the first state and the second state. When the toggle switch 2 is in the first state, the toggle switch 2 forms a closed loop with the power supply 100 and the switch electromagnetic valve 101 respectively. When the toggle switch 2 is in the second state, the toggle switch 2 and the power supply 100 are disconnected, and the toggle switch 2 is connected in series with the control circuit of the switch electromagnetic valve 101. Therefore, when debugging the switch electromagnetic valve 101, the toggle switch 2 can be controlled so that the toggle switch 2 is in the first state. At this time, the toggle switch 2 forms a closed loop with the power supply 100 and the switch electromagnetic valve 101, and the power supply 100 can provide power to the switch electromagnetic valve 101, so that the valve core of the toggle switch 2 can be moved, thereby realizing maintenance or debugging.

[0045] After the inspection or debugging of the switch solenoid valve is completed, the toggle switch 2 can be controlled to be in the second state, so that the switch solenoid valve 101 and the power supply 100 are disconnected. At this time, the switch solenoid valve 101 is independent of the power supply 100, and the switch solenoid valve 101 can be directly controlled to operate.

[0046] It can be seen that when the switch solenoid valve 101 is inspected or debugged, the valve core position of the switch solenoid valve 101 can be controlled through the above connector to avoid manual operation and improve operating efficiency.

[0047] See also Figure 2 , Figure 3 and Figure 4 Optionally, the toggle switch 2 includes a first fixed terminal 21 , a second fixed terminal 22 and a movable terminal 23 , and the first fixed terminal 21 and the second fixed terminal 22 are located in the housing 1 and connected to the housing 1 .

[0048] The first fixed terminal 21 is used to be electrically connected to the power source 100 , and the second fixed terminal 22 is used to be electrically connected to the control circuit of the switch solenoid valve 101 .

[0049] The movable terminal 23 is partially located in the housing 1 and is movably located between the first fixed terminal 21 and the second fixed terminal 22 . The movable terminal 23 is electrically connected to the switch solenoid valve 101 .

[0050] When the toggle switch 2 is in the first state, the movable terminal 23 is electrically connected to the first fixed terminal 21. When the toggle switch 2 is in the second state, the movable terminal 23 is electrically connected to the second fixed terminal 22.

[0051] In the above implementation, the toggle switch 2 is configured as a structure of a first fixed terminal 21, a second fixed terminal 22, and a movable terminal 23, and can be electrically connected to the power source 100 through the first fixed terminal 21, and the second fixed terminal 22 is electrically connected to the control circuit of the switch solenoid valve 101. At the same time, by controlling the movement of the movable terminal 23, the movable terminal 23 is electrically connected to the first fixed terminal 21 or the second fixed terminal 22, so as to control the toggle switch 2 to be in different states.

[0052] For example, in actual use, when the switch solenoid valve 101 needs to be debugged, the movable terminal 23 can be controlled so that the movable terminal 23 contacts the first fixed terminal 21 to achieve electrical connection, and the toggle switch 2 is in the first state. At this time, the toggle switch 2 forms a closed loop with the power supply 100 and the switch solenoid valve 101. The power supply 100 can provide power to the switch solenoid valve 101, so that the valve core of the toggle switch 2 can move, thereby achieving maintenance or debugging.

[0053] When the switch solenoid valve 101 is inspected or debugged, the movable terminal 23 can be controlled so that the movable terminal 23 contacts the second fixed terminal 22 to achieve electrical connection. The toggle switch 2 is in the second state, and the switch solenoid valve 101 and the power supply 100 are disconnected. At this time, the switch solenoid valve 101 is independent of the connector, and the switch solenoid valve 101 can be directly controlled to operate.

[0054] Optionally, the first fixed terminal 21 and the second fixed terminal 22 are both U-shaped structural members, and the first fixed terminal 21 has a first opening 210 , and the second fixed terminal 22 has a second opening 220 , and the first opening 210 and the second opening 220 are arranged opposite to each other and are located on the same straight line.

[0055] When the toggle switch 2 is in the first state, the movable terminal 23 is located in the first opening and contacts the first fixed terminal 21 .

[0056] When the toggle switch 2 is in the second state, the movable terminal 23 is located in the second opening and contacts the second fixed terminal 22 .

[0057] In the above implementation, the first fixed terminal 21 and the second fixed terminal 22 are both set as U-shaped structural members, and the movable terminal 23 can be clamped and limited by the U-shaped structural member. At the same time, the opening of the U-shaped structural member (the first opening 210 or the second opening 220) can facilitate contact with the first fixed terminal 21 and the movable terminal 23, or increase the contact area between the second fixed terminal 22 and the movable terminal 23, thereby improving the contact sensitivity of the movable terminal 23 with the first fixed terminal 21 and the second fixed terminal 22 respectively, ensuring that there is no false contact between them.

[0058] Figure 5 For a structural diagram of the second fixed terminal provided in the embodiment of the present disclosure, see Figure 5 Optionally, the first fixed terminal 21 and the second fixed terminal 22 have the same structure. The first fixed terminal 21 and the second fixed terminal 22 both include a first contact head 201, a second contact head 202 and a connecting arm 203, and the first contact head 201 and the second contact head 202 are respectively located on the same side of the axial direction of the connecting arm 203.

[0059] The first contact head 201 and the second contact head 202 are respectively connected to two ends of the connecting arm 203 , and define a U-shaped structure with the connecting arm 203 .

[0060] The first contact head 201 and the second contact head 202 are conductors, and at least a part of the middle portion of the connecting arm 203 is an insulator.

[0061] Figure 6 The schematic diagram of the structure of the movable terminal provided in the embodiment of the present disclosure is shown in FIG. Figure 6 The movable terminal 23 includes an operating member 231, a third contact head 232 and a fourth contact head 233. The third contact head 232 and the fourth contact head 233 are respectively connected to one side of the operating member 231 along the axial direction of the connecting arm 203 and are located in the housing 1.

[0062] Combination Figure 4 The third contact head 232 and the fourth contact head 233 are both electrically connected to the switch solenoid valve 101 , the third contact head 232 is used to be electrically connected to the first contact head 201 , and the fourth contact head 233 is used to be electrically connected to the second contact head 202 .

[0063] In the above implementation, the first fixed terminal 21 and the second fixed terminal 22 are both configured as a first contact head 201, a second contact head 202 and a connecting arm 203, and the first contact head 201 and the second contact head 202 can be connected together through the connecting arm 203. The first contact head 201 and the second contact head 202 can be used as a live wire connector and a neutral wire connector, respectively, and connected to the live wire and the neutral wire.

[0064] Similarly, the movable terminal 23 is configured as a third contact head 232 and a fourth contact head 233 , so that the third contact head 232 and the fourth contact head 233 can be used as a live wire connector and a neutral wire connector respectively to connect to the live wire and the neutral wire.

[0065] Moreover, when the movable terminal 23 is in the first state, the third contact head 232 contacts the first contact head 201 in the first fixed terminal 21 to achieve electrical connection, and the fourth contact head 233 contacts the second contact head 202 in the first fixed terminal 21 to achieve electrical connection.

[0066] When the movable terminal 23 is in the second state, the third contact head 232 contacts the first contact head 201 in the second fixed terminal 22 to achieve electrical connection, and the fourth contact head 233 contacts the second contact head 202 in the second fixed terminal 22 to achieve electrical connection.

[0067] Optionally, the first contact 201 , the second contact 202 , the third contact 232 and the fourth contact 233 are all copper sheets.

[0068] In the above implementation, the first contact head 201, the second contact head 202, the third contact head 232 and the fourth contact head 233 are set as copper sheets because copper has a higher conductivity, which can reduce energy loss and reduce the heat generated by the toggle switch, so that the current can maintain a higher efficiency during the transmission process of the toggle switch.

[0069] In other examples, the first contact head 201 , the second contact head 202 , the third contact head 232 and the fourth contact head 233 may also be other conductive metals, such as aluminum foil, silver sheet, iron sheet, gold sheet, etc.

[0070] See again Figure 1 Optionally, the connector further includes a control switch 3 , and a portion of the control switch 3 is located in the housing 1 and connected to the housing 1 .

[0071] The control switch 3 is connected in series between the power supply 100 and the toggle switch 2 for controlling the on-off connection between the toggle switch 2 and the power supply 100 so that the toggle switch 2 and the power supply 100 and the switch solenoid valve 101 can form a closed loop.

[0072] In the above implementation, the control switch 3 is used to control the connection between the power supply 100 and the toggle switch 2. That is, it controls whether the circuit formed by the toggle switch 2, the power supply 100 and the switch solenoid valve 101 is a closed loop, thereby improving the safety of the power supply 100.

[0073] For example, when the toggle switch 2 is connected to the switch solenoid valve 101 and the power supply 100 respectively, the power supply 100 and the toggle switch 2 can be disconnected by the control switch 3, and there is no current flow between the power supply 100 and the toggle switch 2, which is convenient for personnel to operate.

[0074] When the switch solenoid valve 101 needs to be debugged or repaired, the toggle switch 2 can be controlled in advance to be in the first state, and then the control switch 3 is operated to connect the power supply 100 to the toggle switch 2, so that the circuits formed by the toggle switch 2, the power supply 100 and the switch solenoid valve 101 are closed loops.

[0075] Optionally, the control switch 3 is a push switch.

[0076] In the above implementation, the control switch 3 is set as a push switch, and the on / off of the circuit formed by the toggle switch 2, the power supply 100 and the switch solenoid valve 101 can be controlled by pressing, and the on / off of the circuit formed by the toggle switch 2, the power supply 100 and the switch solenoid valve 101 can be intuitively judged according to the pressing state of the control switch 3. For example, when the control switch 3 is in the downward pressing state, the circuit formed by the toggle switch 2, the power supply 100 and the switch solenoid valve 101 is a closed circuit. When the control switch 3 is in the upward dialing state, the circuit formed by the toggle switch 2, the power supply 100 and the switch solenoid valve 101 is an open / closed circuit.

[0077] In other examples, the control switch 3 may also be other switch components, such as a toggle switch component, etc. As long as the on / off between the toggle switch 2 and the power source 100 can be controlled, the present disclosure does not impose any limitation thereto.

[0078] Optionally, the power supply 100 is integrated in the housing 1 .

[0079] In the above implementation, the power supply 100 is integrated in the housing 1, so that the switch solenoid valve can still be inspected or debugged without arranging the power supply, thereby expanding the scope of use of the connector.

[0080] In the embodiment of the present disclosure, the power supply 100 may also be a fixed socket. The connector includes a plug, which is electrically connected to the toggle switch 2 and is used to be inserted into the socket.

[0081] Optionally, the housing 1 is a plastic structural component, so that the connector can be insulated externally and the internal electrical conductors can be protected.

[0082] On the other hand, the embodiment of the present disclosure also provides a control method for a switch solenoid valve, which is implemented based on the connector provided above. Figure 7 As shown, the control method includes:

[0083] S701: Control the toggle switch of the joint to be in a first state, so that the toggle switch is electrically connected to the power supply and the switch solenoid valve respectively to form a closed loop.

[0084] The connector is the connector for switching the solenoid valve mentioned above.

[0085] The connector is arranged near the switch solenoid valve.

[0086] S702: Control the on / off of the closed circuit and the current of the closed circuit, and debug or repair the switch solenoid valve.

[0087] Since the toggle switch 2 is movably connected to the housing 1, and the toggle switch 2 is freely switched between the first state and the second state. When the toggle switch 2 is in the first state, the toggle switch 2 forms a closed loop with the power supply 100 and the switch electromagnetic valve 101 respectively. When the toggle switch 2 is in the second state, the toggle switch 2 and the power supply 100 are disconnected, and the toggle switch 2 is connected in series with the switch electromagnetic valve 101. Therefore, when debugging the switch electromagnetic valve 101, the toggle switch 2 can be controlled so that the toggle switch 2 is in the first state. At this time, the toggle switch 2 forms a closed loop with the power supply 100 and the switch electromagnetic valve 101, and the power supply 100 can provide power to the switch electromagnetic valve 101, so that the valve core of the toggle switch 2 can be moved, thereby realizing maintenance or debugging.

[0088] That is to say, when the switch solenoid valve 101 needs to be debugged, the movable terminal 23 in the toggle switch 2 can be controlled so that the movable terminal 23 contacts the first fixed terminal 21 to achieve electrical connection, and the toggle switch 2 is in the first state. At this time, the toggle switch 2 forms a closed loop with the power supply 100 and the switch solenoid valve 101. The power supply 100 can provide power to the switch solenoid valve 101, so that the valve core of the toggle switch 2 can move, thereby achieving maintenance or debugging.

[0089] S703: Control the toggle switch to be in the second state, so that the switch solenoid valve is connected in series with the control circuit of the toggle switch.

[0090] After the inspection or debugging of the switch solenoid valve is completed, the toggle switch 2 can be controlled to be in the second state, so that the switch solenoid valve 101 and the power supply 100 are disconnected. At this time, the switch solenoid valve 101 is independent of the connector, and the switch solenoid valve 101 can be directly controlled to operate. In other words, after the inspection or debugging of the switch solenoid valve 101 is completed, the movable terminal 23 can be controlled so that the movable terminal 23 contacts the second fixed terminal 22 to achieve electrical connection, the toggle switch 2 is in the second state, the switch solenoid valve 101 and the power supply 100 are disconnected. At this time, the switch solenoid valve 101 is independent of the connector, and the switch solenoid valve 101 can be directly controlled to operate.

[0091] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
