Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, and in particular to a convenient-to-install clamp-type temperature sensor. Background Technology

[0002] Currently, most pipe heating or cooling equipment on the market, such as wall-hung boilers, water heaters, HVAC systems, cooling pipes, and underfloor heating systems, use temperature sensors in hexagonal, bullet-shaped, or cylindrical shapes. These types of temperature sensors require drilling and tapping in the pipes before they can be used, which is cumbersome in pipe production and results in high labor costs. Furthermore, during installation, the connecting wires are easily damaged or broken when workers use electric or pneumatic tools to tighten the threads. Since the connecting wires extend in a straight line from the sensor, they need to be bent during production for easy installation. This process reduces production efficiency and increases costs. Therefore, we have introduced a new, convenient-to-install pipe clamp-type temperature sensor. Utility Model Content

[0003] The main purpose of this invention is to provide a conveniently installed clamp-type temperature sensor, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A convenient-installation clamp-type temperature sensor includes a pipe, a spring clip installed on the outside of the pipe, a positioning housing attached to the upper part of the spring clip, an NTC positioning hole at the right end of the positioning housing, an NTC connecting wire threaded through the NTC positioning hole, an NTC diode resistor on the left side of the NTC connecting wire, a connector on the right side of the NTC connecting wire, and epoxy resin filling the NTC positioning hole.

[0006] Preferably, the upper part of the spring clip has a notch, and the lower part of the spring clip has an opening, and the diameter of the opening at its maximum point on the spring clip is larger than the inner diameter.

[0007] By adopting the above technical solution, the notch can serve as a clamping mechanism and also allows for quick installation, while the large opening can serve as a directional tool, facilitating customer assembly and disassembly.

[0008] Preferably, the end face of the positioning shell that contacts the pipe is provided with an arc surface, and the positioning shell is designed in the shape of a "U". The groove on the positioning shell is adapted to the spring clip.

[0009] By adopting the above technical solutions: the arc surface can ensure that the positioning shell is in complete contact with the pipeline, which can prevent the temperature from being too high or too low due to untimely temperature sensing at the temperature measuring end face, thus ensuring the accuracy of NTC temperature measurement. The positioning shell is designed in a "U" shape to prevent the positioning shell from shifting or falling off during use.

[0010] Preferably, the opening of the NTC positioning hole is provided with a large chamfer.

[0011] By adopting the above technical solution, the chamfer can effectively control the problem of epoxy resin overflowing onto the four sides of the positioning shell when the production personnel put the NTC connecting wire into the shell too quickly during the potting operation.

[0012] Preferably, the NTC connecting wire and terminal are crimped and fixed, assembled with the connector as a wire harness, and the wire harness is welded to the NTC diode resistor using a pressure welding process.

[0013] Preferably, the glass shell of the NTC diode resistor is attached to the bottom of the NTC positioning hole.

[0014] By adopting the above technical solutions, the problem of uncertainty can be avoided at the source.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The positioning housing is equipped with NTC positioning holes, which serve as a foolproof design during production, ensuring the NTC diode glass shell fits snugly to the bottom and preventing misalignment issues from the outset. The contact surface between the positioning housing and the pipe is designed as an arc surface to ensure complete contact. The combination of the NTC positioning holes and the arc surface prevents the temperature from being too high or too low due to untimely temperature sensing at the temperature measuring end, ensuring accurate NTC temperature measurement. The positioning housing is designed with a "U" shape to prevent displacement or detachment during use. The opening of the positioning housing has a large chamfer, which effectively controls the epoxy resin from being squeezed out by workers too quickly when inserting the NTC connecting wire into the positioning housing during the potting process. This prevents epoxy resin from overflowing onto the perimeter of the positioning housing, avoiding reduced production efficiency and additional cleaning steps.

[0017] 2. The spring clip is designed for quick installation, and since the product needs to be fixed to the pipe, the fixing structure is designed in a circular shape. The circular fixing position has a notch, which is 2mm to 3mm smaller than the diameter of the circle. This notch serves to lock the clip in place and allows for quick installation. The front end of the notch has a large opening, which can be used for orientation and facilitates customer installation and disassembly.

[0018] 3. While ensuring its performance, this structure achieves the effect of resistor centering, simplifies the production process, avoids inaccurate temperature measurement caused by resistors being too close to the edge, improves production efficiency, enhances product quality, and reduces production costs and the loss of defective products. This structure can significantly improve production efficiency during the installation and disassembly of the whole machine, enabling the whole machine manufacturer to reduce the production of finished products and shorten the installation cycle. With its high quality and low price, it attracts customers' attention, facilitates better product promotion, and enhances the competitiveness of the whole machine. Attached Figure Description

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A convenient-installation clamp-type temperature sensor includes a pipe 1, a spring clip 2 installed on the outside of the pipe 1, a positioning housing 3 clamped and connected to the upper part of the spring clip 2, an NTC positioning hole 4 opened at the right end of the positioning housing 3, an NTC connecting wire 5 passing through the NTC positioning hole 4, an NTC diode resistor 6 provided on the left side of the NTC connecting wire 5, a connector 7 provided on the right side of the NTC connecting wire 5, and epoxy resin 8 filling the NTC positioning hole 4.

[0029] In this embodiment, the upper part of the spring clip 2 is provided with a notch, and the lower part of the spring clip 2 is provided with an opening. The diameter of the largest opening on the spring clip 2 is larger than the inner circle diameter. The end face of the positioning shell 3 that contacts the pipe 1 is provided with an arc surface, and the positioning shell 3 is designed in the shape of a "U". The groove on the positioning shell 3 is adapted to the spring clip 2.

[0030] The above solution involves: NTC positioning holes 4 on the positioning housing 3, which, through structural design, force the NTC diode glass shell to adhere tightly to the bottom, preventing positional shifts during installation and ensuring rapid centering. This ensures accurate positioning of the temperature sensing element from the outset. The end face in contact with the pipe 1 is designed with an arc shape to ensure complete fit between the positioning housing 3 and the pipe 1, reducing contact gaps and preventing temperature measurement deviations due to delayed temperature sensing, thus improving measurement accuracy. The positioning housing 3 is designed in a U-shape to match the structure of the spring clip 2, preventing displacement or detachment during use. The spring clip 2 uses a circular fixing structure to meet pipe installation requirements, with a notch at the fixing position. The notch's width is 2-3mm smaller than the diameter of the circle, achieving a locking effect and supporting rapid installation.

[0031] In this embodiment, the opening of the NTC positioning hole 4 is provided with a large chamfer. The NTC connecting wire 5 and the terminal are crimped and fixed, and assembled with the connector 7 as a wire harness. The wire harness is welded to the NTC diode resistor 6 using a pressure welding process. The glass shell of the NTC diode resistor 6 is attached to the bottom of the NTC positioning hole 4.

[0032] Through the above solution: In the potting operation, the large chamfer at the opening of the NTC positioning hole 4 provides a smooth guide path for the NTC connecting wire 5, avoiding the epoxy resin 8 from being squeezed out due to excessive installation speed, reducing subsequent appearance cleaning processes, improving production efficiency, and the glass shell of the NTC diode resistor 6 is tightly attached to the bottom of the NTC positioning hole 4, avoiding the problem of misalignment from the source.

[0033] It should be noted that this utility model is a convenient clamp-type temperature sensor for installation. During use, the NTC connecting wire 5 and terminals are crimped and fixed, and assembled with the connector 7 as a wire harness. The wire harness is then welded to the NTC diode resistor 6 using a pressure welding process to create a semi-finished product. Epoxy resin 8 is filled into the positioning housing 3, and then the wire harness NTC diode resistor 6 is installed into the positioning housing 3 along the NTC positioning hole 4. The wire harness NTC diode resistor 6 must be installed to the bottom. After the epoxy resin 8 has completely cured, it becomes the finished product. The finished product undergoes visual inspection, withstand voltage testing, resistance testing, and other tests according to customer drawings before it is ready for use. The spring clip 2 is used to create a convenient pipe clamp-type temperature sensor, which is then packaged and encapsulated. Customers only need to install the positioning shell 3 and spring clip 2 on the pipe 1 and connect the connector 7 for use. This structure achieves the effect of resistance centering, simplifies the production process, avoids inaccurate temperature measurement caused by resistors being off-center, improves production efficiency, enhances product quality, and reduces production costs and the loss of defective products. This structure can significantly improve production efficiency during the installation and disassembly of the whole machine, allowing the whole machine manufacturer to reduce the production of finished products and shorten the installation cycle. With its high quality and low price, it attracts customers' attention, facilitates better product promotion, and enhances the competitiveness of the whole machine.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
