[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Features thus defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.
[0036] Please see Figure 1 This embodiment provides a wire clamp 20 control device, which includes a controller 10 and at least one wire clamp 20. The wire clamp 20 can be set to one, two or more, depending on the actual wire clamping needs.
[0037] The wire clamp 20 includes a clamp body 21, which comprises a shape memory alloy body and a heating element 22. The controller 10 has a first control port A and a second control port B. One end of the heating element 22 is electrically connected to the first control port A, and the other end is electrically connected to the second control port B. When there are multiple wire clamps 20, the multiple heating elements 22 are connected in parallel. The controller 10 controls the heating elements 22 to be energized and heated, causing a phase change in the shape memory alloy body for wire clamping.
[0038] In this embodiment, after the wire clamp 20 control device is powered on, the controller 10 controls the heating element 22 to be energized. The heating element 22 heats up, causing a phase change in the shape memory alloy body. Specifically, at low temperatures, the shape memory alloy is in the martensitic phase, and the wire clamp 20 body has a large opening to facilitate wire insertion. When heated to a certain temperature, the shape memory alloy undergoes a phase change, transforming from the martensitic phase to the austenitic phase, and returns to its predetermined shape. That is, the opening of the wire clamp 20 body narrows, tightly pressing the wire and achieving self-locking. Therefore, no tools are needed for wire clamping, making operation simple and improving clamping efficiency.
[0039] Please see Figure 2In some embodiments, the clamp 20 control device further includes a first relay KA1, which may include multiple normally closed contacts. The coil of the first relay KA1 is connected in series between two power control ports 12 in the controller 10. The controller 10 also includes two power ports 11. The first normally closed contact of the first relay KA1 is connected in series between a power line, such as the live wire L, and one of the power ports 11 in the controller 10. The other power port 11 is used to connect to the neutral wire N. One end of the second normally closed contact of the first relay KA1 is connected to the first control port A, and the other end of the second normally closed contact of the first relay KA1 is connected to one end of the heating element 22. The controller 10 is used to control the state of the first relay KA1 to control the heating state of the heating element 22.
[0040] When the control device for the wire clamp 20 is powered on, the first normally closed contact and the second normally closed contact of the first relay KA1 are closed, and the heating element 22 is powered on and enters the heating state. Since the first relay KA1 is equivalent to a main power switch, when multiple wire clamps 20 are installed, multiple wire clamps 20 can be controlled to clamp wires simultaneously, improving clamping efficiency. After the heating element 22 has heated for a certain period of time and the shape memory alloy body has completed clamping, the first normally closed contact and the second normally closed contact of the first relay KA1 can be opened by the controller 10. Then the controller 10 is de-energized, and the heating element 22 is also de-energized, thereby achieving flexible control of the wire clamp 20.
[0041] Please continue reading. Figure 2 In some embodiments, the wire clamp 20 control device further includes temperature sensors 30, the number of which can be set according to the number of wire clamps 20. For example, the number of temperature sensors 30 can be the same as the number of wire clamps 20. One temperature sensor 30 is provided for each wire clamp 20, and the temperature of each wire clamp 20 is independently detected by the temperature sensors 30. The controller 10 includes multiple sets of detection ports 13, the same number as the temperature sensors 30, with each temperature sensor 30 connected in series between a corresponding set of detection ports 13.
[0042] Specifically, the temperature sensor 30 is used to detect the heating temperature of the corresponding heating element 22 and output a corresponding detection signal; the controller 10 is used to control the state of the first relay KA1 according to one or more detection signals. The controller 10 can control the heating element 22 to be de-energized after being energized for a period of time, or it can control the energization and de-energization of the heating element 22 according to the detection signal output by the temperature sensor 30, thereby realizing the flexibility of the control of the heating element 22 and ensuring the reliability of the control of the wire clamp 20.
[0043] Please see Figure 3In some embodiments, the wire clamp 20 control device further includes a second relay, the number of which is the same as the number of wire clamps 20; the controller 10 is provided with multiple sets of selection ports 14, the number of selection ports 14 being the same as the number of second relays; the coil of each second relay is connected in series between the corresponding set of selection ports 14, and the normally open contact of each second relay is connected in series with the corresponding heating element 22; the controller 10 is also used to control the state of the corresponding second relay according to the detection signal.
[0044] In this embodiment, it is equivalent to setting a separate control switch for each heating element 22. For example, if there are three wire clamps 20, then a second relay switch is set for the heating element 22 of each wire clamp 20, such as relays K21, K22 and K23. The controller 10 can control the opening and closing state of the three second relays according to the detection signal output by each temperature sensor 30, thereby independently controlling the state of each wire clamp 20.
[0045] Please see Figure 4 In another embodiment, when there are multiple wire clamps 20, the wire clamp 20 control device further includes at least one third relay KA3. The controller 10 is provided with at least one set of selection ports 14, the number of selection ports 14 being the same as the number of third relays KA3; the coil of the third relay KA3 is connected in series between the corresponding set of selection ports 14; the normally open contact of the third relay KA3 is connected in series with a heating element 22, and the normally closed contact of the third relay KA3 is connected in series with another heating element 22.
[0046] If there are two wire clamps 20, a third relay KA3 is set up. One normally open contact of the third relay KA3 is connected in series with one of the heating elements 22, and the other normally closed contact of the third relay KA3 is connected in series with the other heating element 22. The controller 10 controls the state of the normally open and normally closed contacts of the third relay KA3, which can control one of the two heating elements 22 to work. That is, the two wire clamps 20 can be selected to work by a single relay switch. Compared with setting two independent relays to control the working state of the heating elements 22 respectively, the number of selectable ports 14 in the controller 10 can be reduced.
[0047] Please see Figure 5Of course, in some embodiments, the third relay KA3 has multiple normally closed contacts. For example, in this embodiment, there are three wire clamps 20. The third relay KA3 has one normally open contact and two normally closed contacts. The controller 10 has at least one set of selection ports 14, and the number of selection ports 14 is the same as the number of third relays KA3. The coil of the third relay KA3 is connected in series between the corresponding set of selection ports 14. The normally open contact of the third relay KA3 is connected in series with a heating element 22, the first normally closed contact of the third relay KA3 is connected in series with another heating element 22, and the second normally closed contact of the third relay KA3 is connected in series with yet another heating element 22. In this case, the three wire clamps 20 can be controlled by one third relay KA3, and two of the wire clamps 20 can be selected to work simultaneously, thereby achieving flexibility in controlling the wire clamps 20.
[0048] Please see Figure 6 In another embodiment, the wire clamp 20 control device further includes at least one fourth relay KA4, and the controller 10 is also provided with selection ports 14 corresponding to the number of fourth relays KA4; when the third relay KA3 includes multiple normally closed contacts, the coil of the fourth relay KA4 is connected in series between a corresponding set of selection ports 14; the normally open contact of the third relay KA3 is connected in series between one normally closed contact of the third relay KA3 and the corresponding heating element 22, and the normally closed contact of the third relay KA3 is connected in series between another normally closed contact of the third relay KA3 and the corresponding heating element 22.
[0049] In this embodiment, a fourth relay KA4 can also be set based on the third relay KA3 with multiple normally closed contacts. The normally open and normally closed contacts of the fourth relay KA4 are connected in series with the normally closed contacts of the third relay KA3, respectively. Similarly, selective control of multiple wire clamps 20 can be achieved. If three wire clamps 20 are set, two controllers 10 can be used to select and control one wire clamp 20 to work while the other two wire clamps 20 are not working, thereby achieving flexible control of multiple wire clamps 20.
[0050] Please see Figure 7 In one embodiment, the clamp body 21 is a U-shaped clamp, meaning the shape memory alloy body is U-shaped. At low temperatures, the U-shaped shape memory alloy is in the martensitic phase, and the clamp body 21 has a large opening to facilitate wire insertion. When heated to a certain temperature, the shape memory alloy undergoes a phase transformation, changing from the martensitic phase to the austenitic phase, and returns to its predetermined shape. That is, the opening of the clamp body 20 narrows, tightly pressing the wire and achieving self-locking.
[0051] In one embodiment, the heating element 22 is embedded inside the clamp body 21. In this embodiment, the heating element 22 can be a resistance wire, which is embedded into the clamp body 20. The shape of the resistance wire can be U-shaped, consistent with the shape of the clamp body 21. Embedding the heating element 22 into the clamp body 21, compared to winding the resistance wire around the clamp body 21, can protect the resistance wire and improve the heating uniformity of the clamp body 21, ensuring the phase change of the clamp body 21.
