Description

Technical Field

[0001] The utility model relates to the technical field of temperature controllers, in particular to an automatic capillary winding device for a temperature controller. Background Art

[0002] A thermostat refers to a series of automatic control components that undergo physical deformation inside the switch according to temperature changes in the working environment, thereby producing certain special effects and causing conduction or disconnection actions. It is also called a temperature control switch, temperature protector, temperature controller, or simply a thermostat.

[0003] Or the temperature is transmitted to the temperature controller through the temperature protector, and the temperature controller issues a switch command to control the operation of the equipment to achieve the ideal temperature and energy-saving effect.

[0004] Its working principle is to automatically sample and monitor the ambient temperature in real time through a temperature sensor. When the ambient temperature is higher than the control set value, the control circuit starts and the control hysteresis can be set.

[0005] If the temperature is still rising, when it reaches the set over-limit alarm temperature point, the over-limit alarm function is activated. When the controlled temperature cannot be effectively controlled, the trip function can be used to stop the equipment from continuing to run in order to prevent damage to the equipment.

[0006] It is mainly used in various high and low voltage switch cabinets, dry-type transformers, box-type substations and other related temperature application fields used by the power sector.

[0007] At present, some thermostats need to be connected to a probe structure on the body when in use, and the probe structure is mainly connected through a slender wire. When the slender wire is in use, a layer of flexible capillary will be covered on its outer surface to facilitate the wear-resistant and scratch-resistant protection of the slender wire when in use. However, if the capillary cannot be stably wound in a circle when winding, and irregular bends occur, it will cause damage to the slender wire. Therefore, it is necessary to design a device on the thermostat that can wind up the capillary structure to ensure stable winding storage. Utility Model Content

The terminal 16 is electrically connected to the first wiring ring 15 through a power transmission line 17. The core of the power transmission line 17 is fixed to the first wiring ring 15 by spot welding. A first wiring hole 18 for the power transmission line 17 to pass through is provided on one side wall of the frame 11, and a second wiring hole 19 is provided on the other side wall of the frame 11 in the middle position. The lower end surface of the first plastic disc 13 is installed with a second plastic disc 2 through a vertical rod 110.

[0030] Furthermore, a shaft sleeve 21 is provided through the second plastic disc 2. The shaft sleeve 21 is located at the center of the second plastic disc 2 and is fixedly assembled with screws. A driving shaft 22 is rotatably installed on the inner wall of the shaft sleeve 21. A ceramic plate 23 is fixedly connected to the upper end of the driving shaft 22. The ceramic plate 23 has good insulation and heat insulation effects, which can prevent the normal use of the motor 26 from being affected when the two conductive columns are energized.

[0031] Furthermore, the ceramic plate 23 is located at the center position and fixed with an insulating tube 24 by screws. A second conductive column 28 that is tightly arranged on the lower end surface of the first conductive column 14 is inserted and fixed to the inner wall of the insulating tube 24. A second connecting ring 25 that passes through the insulating tube 24 is welded to one side of the second conductive column 28. The first conductive column 14, the first connecting ring 15, the second connecting ring 25 and the second conductive column 28 are all made of copper alloy material, and have a good stable power transmission effect.

[0032] Furthermore, the wall of the insulating cylinder 24 is composed of an inner layer 241 and an outer layer 242. The outer layer 242 and the inner layer 241 are wrapped around each other. The inner layer 241 is made of a high-strength insulating plastic material, and the outer layer 242 is made of a polyethylene film material. The inner layer 241 penetrates the outer layer 242 and is fixedly connected to the ceramic plate 23. While ensuring that the insulating cylinder 24 stably covers the second conductive column 28, it also ensures that the second conductive column 28 is stably connected during rotation.

[0033] Furthermore, a motor 26 is installed at the lower end of the driving shaft 22, and the outer wall of the motor 26 is fixedly installed to the lower end of the inner wall surface of the frame 11 through symmetrically distributed brackets.

The positive and negative poles of the forward and reverse switch 27 are electrically connected to the electrodes of the motor 26 through wires. The motor 26 is a micro DC model and can be connected in parallel with the circuit elements inside the temperature controller body 1 to the same main circuit.

[0034] Furthermore, the front and back end surfaces of the frame 11 are both tightly attached to the baffles 3, and the upper end surfaces of the two baffles 3 are connected to a support frame 31 with a concave structure. The support frame 31 plays a connecting effect, and the baffles 3 can cover and protect the opening position of the frame 11.

A threaded column 5 that is provided through the built-in sleeve 51 is fixed on the top of the frame 11, and a hexagonal screw sleeve 52 is threadedly connected to the outer wall of the threaded column 5. The hexagonal screw sleeve 52 is tightly arranged with the built-in sleeve 51, so that the baffle 3 can be easily disassembled and the winding structure in the frame 11 can be easily inspected and repaired.

[0037] Working method: When the probe needs to be used, the probe is connected to the second wiring ring 25 through a slender wire covered with a capillary. When the capillary needs to be rolled up, the power supply of the temperature controller body 1 is turned on so that the motor 26 can be energized. By rotating the forward and reverse switch 27, the insulating tube 24 can circle and store the capillary, or release it in the reverse direction when in use.

[0038] When the thermostat body 1 is connected to the probe, the thermostat body 1 is electrically connected to the first wiring ring 15 through the transmission line 17. Through the stable contact between the first conductive column 14 and the second conductive column 28, a stable electrical connection can be achieved, ensuring stable use of the thermostat body 1 and the probe.

[0039] When it is necessary to cover and protect the front and back sides of the frame 11, the support frame 31 with two baffles 3 is used to cover the frame 11. At this time, the two baffles 3 respectively cover the front and back sides of the frame 11, and the threaded column 5 penetrates the built-in sleeve 51 for quick docking and positioning. Then, the hexagonal screw sleeve 52 and the threaded column 5 are threadedly connected to each other to achieve the fixation of the baffle 3 and the frame 11.
