Description

Technical Field

[0001] This utility model relates to the field of thermostat technology, and in particular to a thermostat sealing connection structure. Background Technology

[0002] A thermostat is a device that controls the start and stop of equipment based on changes in the ambient temperature to maintain a set temperature range. It is a core component of modern temperature control systems and is widely used in industrial, commercial, and residential fields, playing a key role in energy conservation and emission reduction, improving comfort, and ensuring the safe operation of equipment.

[0003] Existing thermostats lack protective structures at the wiring connections at the rear end. When operating in humid or dusty environments, these connections can be easily damaged, affecting the normal operation of the thermostat.

[0004] Therefore, given the lack of protective structure at the wiring connection of existing thermostats, which can easily affect the wiring connection when operating in humid or dusty environments, thus affecting the normal operation of the thermostat, a sealed connection structure for the thermostat can be designed. This structure can seal and protect the wiring connection of the thermostat, effectively reducing the impact of the external environment on the wiring connection and ensuring the normal operation of the thermostat. Utility Model Content

[0005] To overcome the problem that existing thermostats lack protective structures at the wiring connections at the rear end, which can easily affect the wiring connections when operating in humid or dusty environments, thus affecting the normal operation of the thermostat.

[0006] The technical solution of this utility model is as follows: a thermostat sealing connection structure, including a thermostat body, wiring points, a protective cover, wire holes, a sealing sleeve, and winding posts. The rear end of the thermostat body is provided with multiple sets of wiring points. The protective cover is fitted around the thermostat body. The rear end of the protective cover has multiple sets of wire holes, which correspond to the wiring points. Each set of wire holes is provided with a sealing sleeve inside. The sealing sleeve has three sets of linearly arranged protrusions inside. Multiple sets of winding posts are fixedly installed at the rear end of the protective cover. The multiple sets of winding posts are located on one side of the multiple sets of wire holes.

[0007] Preferably, by setting a protective cover around the thermostat body, part of the thermostat body's structure and the wiring points at the rear of the thermostat body can be shielded and protected, reducing the impact of the external environment on the wiring points of the thermostat body, thereby ensuring the stability of the connecting cable. The cable through-hole allows the cable to pass through the protective cover and connect to the wiring points at the rear of the thermostat body inside the protective cover. The sealing sleeve compresses and adheres to the outer surface of the connecting cable, preventing external dust and moisture from entering the interior of the protective cover through the cable through-hole and affecting the protective cover. The three sets of protrusions inside the sealing sleeve provide multiple seals to ensure the sealing effect. At the same time, the sealing sleeve compresses the connecting cable and also has a certain fixing effect on the connecting cable, ensuring the stability of the connecting cable. The winding post allows for easy winding and storage of redundant connecting cables, facilitating subsequent inspection and maintenance.

[0008] Preferably, multiple sets of partitions are fixedly installed at the rear end of the thermostat body. The multiple sets of partitions are evenly and linearly arranged, and the multiple sets of partitions alternately separate the multiple sets of wiring points.

[0009] Preferably, a protrusion is provided on the rear side of the thermostat body, and a positioning sleeve is provided on the front end of the protective cover. The positioning sleeve is located outside the protrusion, and four sets of first bolts are provided inside the positioning sleeve. The positioning sleeve is fixedly connected to the thermostat body through the first bolts.

[0010] Preferably, the front end of the positioning sleeve is provided with a sealing ring, which is located inside the positioning sleeve. The surface of the protrusion is provided with a reserved groove, which corresponds to the sealing ring.

[0011] Preferably, both the sealing ring and the reserved groove have V-shaped cross-sections, with the cross-sectional area of ​​the sealing ring being larger than that of the reserved groove.

[0012] Preferably, a control panel is provided at the front end of the thermostat body, and four sets of second bolts are provided at the front end of the thermostat body. The control panel is fixedly connected to the thermostat body through the second bolts.

[0013] Preferably, the inner wall of the protective cover is provided with a thermally conductive rubber pad, which contacts the outer surface of the thermostat body. Multiple heat dissipation plates are fixedly installed around the thermally conductive rubber pad, and the heat dissipation plates penetrate the protective cover.

[0014] The beneficial effects of this utility model are:

[0015] By threading the cables into the protective cover through their respective holes and connecting them to the corresponding terminals at the rear of the thermostat body, the protective cover is then replaced. The sealing sleeve compresses and adheres to the outer surface of the cables passing through the holes, preventing dust and moisture from entering the protective cover and affecting it. The three sets of protrusions inside the sealing sleeve provide multiple layers of sealing, ensuring a tight seal. The compression of the cables by the sealing sleeve also helps to stabilize them. Then, the cables are gently slid within the sealing sleeve to remove any excess cable and wind it around the winding post, thus organizing and storing the cables for future maintenance.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment: a thermostat sealing connection structure, including a thermostat body 1, wiring points 101, a protective cover 2, wire holes 204, sealing sleeves 205, and winding posts 206. Multiple sets of wiring points 101 are provided at the rear end of the thermostat body 1. The protective cover 2 is fitted around the thermostat body 1. Multiple sets of wire holes 204 are provided at the rear end of the protective cover 2, each set corresponding to a set of wiring points 101. A sealing sleeve 205 is provided inside each set of wire holes 204, and the sealing sleeve 205 has three sets of linearly arranged protrusions inside. Multiple sets of winding posts 206 are fixedly installed at the rear end of the protective cover 2, each set located on one side of a set of wire holes 204. By providing the protective cover 2 around the thermostat body 1, the structure of the thermostat body 1 and its rear end can be sealed. The connection point 101 is shielded and protected to reduce the impact of the external environment on the connection point 101 of the thermostat body 1, thereby ensuring the stability of the connection cable. The cable can be easily passed through the protective cover 2 and connected to the connection point 101 at the rear end of the thermostat body 1 inside the protective cover 2 by the wire hole 204. The sealing sleeve 205 can squeeze and adhere to the outer surface of the connection cable to prevent external dust and moisture from entering the interior of the protective cover 2 through the wire hole 204 and affecting the protective cover 2. The three sets of protrusions inside the sealing sleeve 205 can play a multiple sealing role to ensure the sealing effect. At the same time, the sealing sleeve 205 can also fix the connection cable to a certain extent by squeezing the connection cable to ensure the stability of the connection cable. The winding post 206 can be used to easily wind and store redundant connection cables for easy subsequent inspection and maintenance.

[0024] Please see Figure 3 and Figure 4In this embodiment, multiple sets of partitions 102 are fixedly installed at the rear end of the thermostat body 1. The partitions 102 are evenly and linearly arranged, and they alternately separate multiple sets of wiring points 101. By setting the partitions 102 to separate the multiple sets of wiring points 101 at the rear end of the thermostat body 1 one by one, the connected cables are prevented from interfering with each other near the wiring points 101, and short circuits and cross-wiring are prevented. A protrusion 103 is provided on the rear side of the thermostat body 1, and a positioning sleeve 201 is provided on the front end of the protective cover 2. The positioning sleeve 201 is located outside the protrusion 103, and four sets of first bolts 203 are provided inside the positioning sleeve 201. The positioning sleeve 201 is fixedly connected to the thermostat body 1 by the first bolts 203. By setting the positioning sleeve 201, when the protective cover 2 is fitted around the thermostat body 1, it can provide protection for the protective cover 2 by corresponding to the protrusion 103. The cover 2 is positioned and connected and fixed to the thermostat body 1 by the first bolt 203. A sealing ring 202 is provided at the front end of the positioning sleeve 201. The sealing ring 202 is located inside the positioning sleeve 201. A reserved groove 104 is opened on the surface of the protrusion 103, and the reserved groove 104 corresponds to the sealing ring 202. The cross-section of the sealing ring 202 and the reserved groove 104 is V-shaped, and the cross-sectional area of ​​the sealing ring 202 is larger than that of the reserved groove 104. By setting the sealing ring 202 and the reserved groove 104 to cooperate, the connection between the positioning sleeve 201 and the thermostat body 1 can be sealed. The V-shaped structure can effectively ensure the sealing effect. The cross-sectional area of ​​the sealing ring 202 is larger than that of the reserved groove 104. When the sealing ring 202 enters the reserved groove 104, it can squeeze and fill the reserved groove 104, thereby ensuring the sealing effect.

[0025] Please see Figure 1 and Figure 5 In this embodiment, a control panel 3 is provided at the front end of the thermostat body 1, and four sets of second bolts 301 are provided at the front end of the thermostat body 1. The control panel 3 is fixedly connected to the thermostat body 1 through the second bolts 301. The control panel 3 is fixedly installed by the second bolts 301, and the thermostat body 1 can be operated by the control panel 3. A thermally conductive pad 4 is provided on the inner wall of the protective cover 2. The thermally conductive pad 4 is in contact with the outer surface of the thermostat body 1. Multiple sets of heat dissipation plates 401 are fixedly installed around the thermally conductive pad 4, and the heat dissipation plates 401 penetrate the protective cover 2. The thermally conductive pad 4 can conduct the heat generated by the thermostat body 1 to the heat dissipation plates 401, and the heat dissipation plates 401 can increase the heat dissipation area and thus improve the heat dissipation effect.

[0026] When working, remove the first bolt 203, remove the protective cover 2 from the outside of the thermostat body 1, and insert the cables that need to be connected into the inside of the protective cover 2 through the corresponding wire hole 204, and connect them to the corresponding wiring point 101 at the rear end of the thermostat body 1.

[0027] Next, the protective cover 2 is put back on the outside of the thermostat body 1. The positioning sleeve 201 and the protrusion 103 correspond to each other to position the protective cover 2 on the outside of the thermostat body 1. Then, the protective cover 2 is fixed by the first bolt 203. The connection between the positioning sleeve 201 and the thermostat body 1 is sealed by the cooperation of the sealing ring 202 and the reserved groove 104. The V-shaped structure can effectively ensure the sealing effect. The cross-sectional area of ​​the sealing ring 202 is larger than the cross-sectional area of ​​the reserved groove 104. When the sealing ring 202 enters the reserved groove 104, it squeezes and fills the reserved groove 104, thereby ensuring the sealing effect.

[0028] The connecting cable passing through the cable hole 204 can be squeezed and adhered to the outer surface of the connecting cable by the sealing sleeve 205, preventing external dust and moisture from entering the interior of the protective cover 2 through the cable hole 204 and affecting the protective cover 2. The three sets of protrusions inside the sealing sleeve 205 can play a multiple sealing role to ensure the sealing effect. At the same time, the sealing sleeve 205 squeezes the connecting cable and can also play a certain role in fixing the connecting cable to ensure the stability of the connecting cable. Then, the connecting cable is gently pulled out and slid in the sealing sleeve 205 to remove the redundant part of the cable in the protective cover 2 and wrap it around the outside of the winding post 206 to store and organize the connecting cables for easy subsequent maintenance.

[0029] The thermostat body 1 can be controlled using the control panel 3. The heat generated by the thermostat body 1 during operation can be conducted and transferred to the heat sink 401 using the thermal pad 4. The heat sink 401 can increase the heat dissipation area and thus improve the heat dissipation effect, ensuring that the thermostat body 1 can work stably.

[0030] Through the above steps, by placing the protective cover 2 around the thermostat body 1, part of the structure of the thermostat body 1 and the wiring point 101 at the rear end of the thermostat body 1 can be shielded and protected, reducing the impact of the external environment on the wiring point 101 of the thermostat body 1, thereby ensuring the stability of the connecting cable. The sealing sleeve 205 can squeeze and adhere to the outer surface of the connecting cable, preventing external dust and moisture from entering the interior of the protective cover 2 through the wire hole 204 and affecting the connection of the cable at the wiring point 101. At the same time, the sealing sleeve 205 squeezes the connected cable and can also play a certain role in fixing the connected cable, ensuring the stability of the connecting cable. This solves the problem that the existing thermostat lacks a protective structure at the wiring connection at the rear end, which can easily affect the wiring connection when working in a humid or dusty environment, thus affecting the normal operation of the thermostat.
