Description

A thermostat with stable temperature measurement Technical Field

[0001] The present invention relates to the technical field of temperature controllers, and in particular to a temperature controller with stable temperature measurement. Background Art

[0002] Thermostats physically deform inside the switch in response to ambient temperature changes, producing specific effects. These effects trigger a series of automatic control elements, or electronic components, to switch on or off at different temperatures, providing temperature data to the circuit for collection. Existing temperature controllers, once fixed, cannot be easily adjusted and controlled, making wiring adjustments difficult during installation and use. Furthermore, existing sliding-mounted thermostats, while convenient for position adjustment during installation, are susceptible to momentary displacement during use, potentially causing disconnection.

[0003] At present, an existing patent discloses an adjustable thermostat, such as patent publication number: CN217742047U, which includes a first fixed plate, a second fixed plate, a fastening groove, a fixing hole and a thermostat, wherein the thermostat is slidably clamped between the first fixed plate and the second fixed plate, the fastening grooves are symmetrically arranged on the second fixed plate and the first fixed plate, and the fixing holes are opened at the end corners of the first fixed plate and the second fixed plate and the fixed side plate. During the installation and use process, it is convenient to adjust and control the position of the thermostat, and after the use position of the thermostat is determined, even if the thermostat is not firmly fixed and is instantly displaced between the first fixed plate and the second fixed plate, the buffer slider compresses the buffer spring so that the buffer slider, the buffer column, the rotating wheel and the wire wrapped around the rotating wheel can be fully displaced to relieve the force, so that the wire and the thermostat will not be pulled apart.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were found:

[0005] Fixed wire is unstable: Although the existing adjustable thermostat can slide when in use, it requires the wire to move with the device. In addition, in order to ensure that the wire can always follow the device, the length of the wire that can move freely needs to be greater than a certain range of the device. Therefore, in the process of the device moving back and forth, the wire needs to be bent back and forth. This process not only easily causes the wire to reach fatigue strength and break, but also easily affects the normal transmission of the signal, resulting in no deviation in the signal transmission. For this reason, we propose a thermostat with stable temperature measurement.

[0050] The embodiment of the present application solves the technical problems of unstable wire fixing and cumbersome wire connection of existing thermostats when in use by providing a thermostat with stable temperature measurement. When the existing thermostat is in use, due to the cooperation of the wedge-shaped clip and the wedge-shaped slide, the clip is continuously moved toward the cable inside it to clamp the cable, preventing the cable from loosening during use, thereby improving the stability of cable use; due to the cooperation of the direction hook and the hook groove on the inner wall of the slide, the clip is fixed to prevent the clip from loosening during use; due to the use of wire pliers to cut the surface of the cable, a quick electrical connection between the cable and the device is achieved, reducing the difficulty of cable connection and replacement.

[0051] Example 1

[0052] The technical solution in the embodiment of the present application effectively solves the technical problem of unstable fixed wires in existing thermostats during use. The overall idea is as follows:

[0053] In response to the problems existing in the prior art, the present invention provides a thermostat with stable temperature measurement. The thermostat includes a panel 1 for inputting and displaying information, and a terminal block 4 at the rear end of the panel 1 is connected to an external wire through the terminal block 4, thereby electrically connecting the wire to the device. The terminal block 4 fixes the wire in a clamping manner so that the wire cannot be separated from the device, thereby improving the stability and convenience of the device wiring, and ultimately enabling the thermostat to operate stably and normally:

[0054] Panel 1, used for displaying information;

[0055] The terminal block 4 is installed at the rear end of the panel 1 and is used to connect with the cable to complete the electrical connection between the device and the wire; and

[0056] The clamping member 6 is sleeved on the outside of the cable, and the clamping member 6 is docked through the sliding groove on the back of the wiring seat 4 to reserve space for the cable;

[0057] The clamping member 6 includes two wedge-shaped clips 61 that slide in a wedge-shaped chute, thereby continuously squeezing the clips 61 toward the cable, thereby improving the connection strength between the cable and the clips 61. In addition, a reverse hook 62 is installed on the outside of the clip 61, which hooks into the corresponding hook groove on the inner wall of the chute, thereby preventing the clip 61 from moving, thereby maintaining the clamping state of the clip 61 and the cable, as shown in Figure 7;

[0058] The inner wall of the slide is provided with a hook groove, and the slide is wedge-shaped, which is convenient for cooperation with the wedge-shaped clip 61, so that the closer the clip 61 is to the end of the terminal block 4, the greater the clamping force on the cable, thereby gradually applying clamping force to the cable, so that the cable and the clip 61 are stably connected together.

[0059] In some examples, the clip 61 is connected to the hook groove inside the slide groove through the reverse hook 62, as shown in FIG7 , thereby limiting the movable position of the clip 61.

[0060] In some examples, two clips 61 are respectively provided on both sides of the cable, so that when the clips 61 move, they clamp the cable like a "clamp", thereby improving the stability of the connection between the clips 61 and the cable;

[0061] Among them, arc grooves are opened on the opposite sides of the two clips 61, and the clips 61 fit with the outer wall of the cable through the arc grooves, which is convenient for corresponding to the outer wall of the cable which is also arc-shaped, thereby increasing the contact surface between the clips 61 and the cable.

[0062] In some examples, a plurality of hook grooves are provided and are evenly spaced along the movement path of the reverse hook 62, so as to facilitate adjustment of the degree of clamping of the cable by the clip 61 as needed;

[0063] The hook groove and the reverse hook 62 have the same specifications, so when the hook groove and the reverse hook 62 are hooked, the clip 61 cannot move freely.

[0064] In some examples, the rear end of the panel 1 is connected to a mounting base 2, and a docking base 3 (which stores a PCB board and circuits therein) is provided at the rear end of the mounting base 2, and a wiring base 4 is installed at the rear of the docking base 3, as shown in Figures 2 and 3.

[0065] In the specific implementation process, the two clips 61 are first bonded to the two sides of the cable respectively, and then the cable with the clips 61 is placed in the slide groove at the rear end of the terminal block 4, as shown in Figure 4, and the cable is pulled to move upward. First, because the cable and the clips 61 are bonded to each other; second, the inner wall of the slide groove and the shape of the clip 61 are wedge-shaped, so during the sliding process, the clip 61 moves with the cable, and as the clip 61 continues to slide, the wedge-shaped clip 61 moves toward the cable under the action of the inner wall of the slide groove, thereby increasing the clamping force on the cable, so that the cable and the clip 61 are further fixed together. Therefore, the more the cable is pulled outward, the greater the connection strength between the clip 61 and the cable.

[0066] Secondly, since the outer wall of the clip 61 is provided with a reverse hook 62 (that is, the hooking direction of the reverse hook 62 is opposite to the movement direction of the clip 61, and the movement direction of the clip 61 moves in the direction of decreasing width of the wedge-shaped slide), and the inner wall of the slide is provided with a hook groove corresponding to the reverse hook 62, during the movement of the clip 61, the reverse hook 62 on its outside moves together, and when the reverse hook 62 corresponds to the hook groove on the inner wall of the slide, the reverse hook 62 is hooked together with the hook groove, as shown in Figure 7, at this time the clip 61 cannot slide toward the side where the slide gradually increases, thereby fixing the cable in the terminal block 4. Since the inner wall of the slide is provided with a number of hook grooves at equal intervals, it can be fixed at different positions according to the diameter of the cable, thereby improving the applicability of the device and ultimately preventing the cable from shaking during use, thereby improving the stability of the thermostat.

[0067] Example 2

[0068] Based on Example 1, the present invention effectively solves the technical problem of cumbersome wire connections when using existing thermostats. The overall idea is as follows:

[0069] A cover plate 5 is hingedly connected to the bottom of the wiring seat 4, and the cover plate 5 can cover the rear part of the wiring seat 4, thereby limiting the range of movement of the cable in the chute;

[0070] Among them, bolt holes are provided on the outside of the cover plate 5 and the outside of the terminal block 4, and when the cover plate 5 is covered on the rear part of the terminal block 4, the threaded holes between the two correspond to each other, which makes it convenient to connect the cover plate 5 and the terminal block 4 together by bolts, thereby improving the firmness of the connection between the two.

[0071] In some examples, a conductive member 7 is installed on the cover plate 5 facing the terminal block 4, and the cable is broken through the conductive member 7 so that the copper wire inside the cable can contact the conductive member 7. At this time, the cable and the conductive member 7 can be energized;

[0072] The conductive member 7 includes a wire breaker 73 provided on the cover plate 5. The wire breaker 73 corresponds to a guide groove provided on the surface of the chute (the guide groove is used to reserve space for the wire breaker 73). As shown in FIG8 , when the cover plate 5 is connected to the terminal block 4, the wire breaker 73 can correspond to the cable in the chute.

[0073] The wire breaking pliers 73 are provided with a wire breaking knife on one side facing the terminal block 4, and the wire breaking pliers 73 cuts the outer wall of the cable through the wire breaking knife, as shown in FIG8 ;

[0074] The wire breaker 73 is electrically connected to the panel 1 through a wire. Since the copper wire inside the cable can contact the conductive member 7 when the conductive member 7 breaks the cable skin, the current transmitted from the cable can be conducted to the panel 1 when the wire breaker 73 is connected to the panel 1 through a wire, so that the cable and the panel 1 are electrically connected.

[0075] In some examples, a V-shaped slot is provided on one side of the wire breaker 73, and a wire breaking knife is installed inside the slot, so as to facilitate wire breaking of cables of different thicknesses.

[0076] When the wire breaker 73 and the conductive seat 74 are fitted together, the wire breaker 73 contacts the copper wire inside the conductor, and at this time, the cable and the wire breaker 73 can be energized.

[0077] In some examples, a sliding rod 71 is installed on the outside of the cover plate 5, and the extending direction of the sliding rod 71 is consistent with the extending direction of the sliding groove;

[0078] A slider 72 is slidably mounted on the outside of the sliding rod 71 , and the slider 72 is connected to the rear of the wire breaker 73 , so that the wire breaker 73 can slide relative to the cover plate 5 when the wire breaker 73 contacts the cable.

[0079] In some examples, a conductive seat 74 is embedded in the interior of the slide groove, and an embedding groove is opened on the top of the conductive seat 74. The conductive seat 74 is electrically connected to the panel 1 through a wire. Therefore, when the wire breaker 73 corresponds to the embedding groove, the wire breaker 73 can be electrically connected to the conductive seat 74 and indirectly electrically connected to the panel 1.

[0080] When the cover plate 5 and the terminal block 4 are fitted together, the wire breaker 73 is inserted into the embedding groove, so that the wire breaker 73 contacts the conductive block 74, facilitating the passage of current.

[0081] After the cable is fixed, the cover plate 5 is covered on the terminal block 4. Since the wire breaker 73 is installed on the inner side of the cover plate 5, the wire breaker 73 on the cover plate 5 enters the slide groove when the cover plate 5 and the terminal block 4 are docked, and the wire breaking knife inside the wire breaker 73 cuts the cable in the slide groove, so that the wire breaker 73 contacts the copper wire inside the wire. At this time, the cable and the wire breaker 73 can be energized, and the wire breaker 73 fits the conductive seat 74 in the slide groove. Since the conductive seat 74 is electrically connected to the panel 1 through the wire, when the wire breaker 73 corresponds to the embedded groove, the wire breaker 73 can be electrically connected to the conductive seat 74, and indirectly electrically connected to the panel 1, completing the electrical connection between the cable and the panel 1.

[0082] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
