Description

Technical Field

[0001] This utility model relates to the field of thermometer technology, specifically to a thermometer with a replaceable connector. Background Technology

[0002] A thermometer is an instrument used to measure temperature. It can measure the temperature of the surface and the internal temperature of food or objects, depending on the type and design of the thermometer.

[0003] The thermometer mainly consists of a metal probe and an internal main control circuit board. When in use, the metal probe is inserted into the object to be measured or placed on the surface of the object. The metal probe collects the real-time temperature of the object to be measured, converts it into a digital signal, and then feeds it back to the corresponding temperature measurement module on the main control circuit board through a data cable. The actual temperature is then displayed on the screen for the user to read.

[0004] Currently, thermometers are connected to different probes depending on the application scenario.

[0005] However, most thermometers currently use a connectorless or single-connector design, which does not allow for connector interchangeability and limits their application scenarios. Some thermometers use a single threaded or flanged interface, which allows for the replacement of different probes by changing the connector, but this process requires tools.

[0006] Therefore, there is an urgent need for a thermometer with interchangeable connectors that allows for quick assembly and disassembly of the thermometer body and different types of probes without the use of tools. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Example 1 The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0023] This embodiment provides a thermometer with replaceable connectors, including a main body 1, a conversion socket 2, and a probe module 3. The main body 1 includes a main housing 11, a display screen 12, a main control circuit board 13, and a compensation wire 14. The display screen 12 is embedded in the main housing 11, and the main control circuit board 13 is disposed within the main housing 11. The display screen 12 and the compensation wire 14 are electrically connected to the main control circuit board 13. The conversion socket 2 includes a socket housing 21, a positive socket connector 22, and a negative socket connector 23. The positive and negative socket connectors 22 and 23 are detachably fixed within the socket housing 21 and are electrically connected to the compensation wire 14. The probe module 3 includes a positive plug connector 31, a negative plug connector 32, a plug bottom shell 33, a plug front shell 34, a fastening cap 35, and a probe 36. The plug bottom shell 33 and the plug front shell 34 are engaged to form a first space. One end of the plug positive connector 31 and the plug negative connector 32 is fixed in the first space, and the other end extends out of the first space from the plug bottom shell 33. The fastening cap 35 is sleeved on the plug front shell 34 and detachably connected to the socket housing 21. The plug positive connector 31 is inserted into the socket positive connector 22, and the plug negative connector 32 is inserted into the socket negative connector 23. One end of the probe 36 extends into the first space and connects to the plug positive connector 31 and the plug negative connector 32.

[0024] In this embodiment, in order to ensure the accuracy of temperature measurement and to prevent misinsertion and misuse, the socket positive terminal 22, the socket negative terminal 23, the plug positive terminal 31, and the plug negative terminal 32 are respectively the K-type thermocouple socket positive terminal, the K-type thermocouple socket negative terminal, the K-type thermocouple plug positive terminal, and the K-type thermocouple plug negative terminal.

[0025] In this embodiment, as Figure 2 As shown, the adapter 2 includes a socket faceplate 24, a socket bottom shell 25, a socket positive connector 22, and a socket negative connector 23. The socket positive connector 22 and socket negative connector 23 are respectively fixed to the socket faceplate 24 or the socket bottom shell 25 in parallel by detachable first fasteners 252 and second fasteners 253. One end of the compensating wire 14 is electrically connected to one end of the socket positive connector 22 and the socket negative connector 23, respectively. Both the socket faceplate 24 and the socket bottom shell 25 have semi-circular grooves 251, which can be matched to form a circular through hole during installation. The compensating wire 14 can pass through this through hole and engage with it. The other end of the compensating wire 14 extends out of the space formed after the socket faceplate 24 and the socket bottom shell 25 are assembled, and extends into the main unit housing 11 to be electrically connected to the main control circuit board 13.

[0026] like Figure 6 As shown, the socket faceplate 24 and the socket bottomplate 25 can be assembled together to form a socket housing 21. The socket housing 21 includes a housing body 211 and a first connecting portion 212. The first connecting portion 212 extends from one end of the housing body 211. The housing body 211 is used to accommodate and fix the compensating wire 14, the socket positive terminal connector 22, and the socket negative terminal connector 23. The socket positive terminal connector 22 and the socket negative terminal connector 23 are detachably fixed inside the housing body 211. After being fixed, one end of the socket positive terminal connector 22 and the socket negative terminal connector 23 extends into the space enclosed by the first connecting portion 212. The first connecting portion 212 is cylindrical, and its outer end face is provided with a first thread 2124. Corresponding to the first end face 2121 of the first connecting portion 212, it is provided with a first through hole 2122 and a second through hole 2123. The first through hole 2122 and the second through hole 2123 are used to allow the positive terminal 31 and the negative terminal 32 of the plug to pass through and electrically connect with the positive terminal 22 and the negative terminal 23 of the socket, respectively. In this embodiment, the width of the first through hole 2122 is greater than the width of the second through hole 2123, or the width of the first through hole 2122 is less than the width of the second through hole 2123. This asymmetrical width is designed to prevent the positive terminal 31 and the negative terminal 32 of the plug from being inserted into the wrong position, which is a mistake-proof design.

[0027] like Figure 2 and Figure 3As shown, the probe module 3 includes a positive connector 31, a negative connector 32, a bottom shell 33, a top shell 34, a fastening cap 35, and a probe 36. The bottom shell 33 includes a circular base 331 and a reinforcing portion 334 extending axially from the circular base 331. A third through hole 3311 and a fourth through hole 3312 are spaced apart at positions corresponding to the first through hole 2122 and the second through hole 2123, respectively. The third through hole 3311 and the fourth through hole 3312 pass through the reinforcing portion 334 and the circular base 331 to form through holes. The positive connector 31 and the negative connector 32 pass through the third through hole 3311 and the fourth through hole 3312, respectively. The widths of the third through hole 3311 and the fourth through hole 3312 are different, and the widths of the positive connector 31 and the negative connector 32 are also different. The positive terminal 31 and negative terminal 32 of the plug pass through the third through hole 3311 and the fourth through hole 3312, respectively, which are of appropriate width. This is also a foolproof design. The edge of the reinforcing part 334 is also provided with two symmetrically arranged first grooves 3341. The circular base 331 is also provided with two symmetrically arranged first engaging parts 332 with identical structures at the positions corresponding to the first grooves 3341. The first engaging part 332 has a first engaging part body 3321 extending axially along the circular base and a first engaging part 3322 extending outward from the end of the first engaging part body 3321. The outer end face of the first engaging part 3322 is arc-shaped so that it can deform in opposite directions when engaged. The first groove 3341 on the reinforcing part 334 is designed to prevent the first engaging part 3322 from colliding with it when deformed. A long strip-shaped abutment part 333 is provided in the middle of the reinforcing part 334 in a direction extending perpendicular to the length of the third through hole 3311.

[0028] like Figure 2 and Figure 4As shown, the plug housing 34 includes a first hollow cylindrical portion 346 and a second hollow cylindrical portion 347, which are connected. When the plug housing 34 and the plug bottom housing 33 are assembled, the inner end face of the first hollow cylindrical portion 346 is provided with a first recess 3412 and a first engaging through hole 3411 corresponding to the position of the first engaging portion 332. The first recess 3412 and the first engaging through hole 3411 constitute the first engaging portion 341. The first recess 3412 can restrict the displacement of the first engaging portion body 3321 in the left and right directions, and the first engaging through hole 3411 can engage with the first engaging portion 3322. A limiting groove 342 is provided on the end face where the first hollow cylindrical portion 346 and the second hollow cylindrical portion 347 are connected. The limiting groove 342 penetrates the fifth through hole 343 of the first hollow cylindrical portion 346. Wire receiving portions 344 are provided on both sides of the fifth through hole 343. The fifth through hole 343 is used for the probe 36 to pass through the first hollow cylindrical portion 346 and abut against the abutment portion 333. The positive terminal 31 and negative terminal 32 of the plug are also received and engaged in the limiting groove 342 to limit the engagement of the plug face shell 34 and the plug bottom shell 33. The wire receiving portion 344 is used for routing the wire electrically connected from the end of the probe 36 and ultimately connecting the wire to the positive terminal 31 and the negative terminal 32 of the plug. The fifth through hole 343 passes through the first hollow cylindrical portion 346 and the second hollow cylindrical portion 347, and is provided for the probe 36 to pass through. The probe module 3 also includes a first sealing ring 37, which is located in the gap between the fastening cap 35 and the plug housing 34. The first sealing ring 37 is provided for sealing the second hollow cylindrical portion 347 in conjunction with the fastening cap 35.

[0029] like Figure 5 As shown, the fastening cap 35 is also a hollow cylinder and larger than the plug face 34, allowing it to be fitted over the plug face 34. The inner end face of the fastening cap 35 has a second thread 352. When it is fitted onto the engaged plug bottom shell 33 and plug face 34, it rotates to connect with the first thread 2124 of the first connecting part 212. The bottom end face of the fastening cap 35 can abut against the engaged plug bottom shell 33 and plug face 34, thereby securing the positive connector 31 and the negative connector 32 of the plug. The bottom end face of the fastening cap 35 also has a sixth through hole 351, which is also for the probe 36 to pass through.

[0030] During the assembly of probe 36, temperature sensor 32 passes through the sixth through hole 351 and the fifth through hole 343 and is connected to the positive connector 31 and the negative connector 32 of the plug via the wire receiving part 344, respectively. The end of probe body 361 passes through the sixth through hole 351 and the fifth through hole 343 and is engaged between the abutment part 333 and the sixth through hole 351. Therefore, probe 36, positive connector 31 and negative connector 32 of the plug are connected as a whole, and one end of probe 36 is engaged between the abutment part 333 and the sixth through hole 351. Probe module 3 and adapter socket 2 are disconnected and separable.

[0031] When the plug bottom shell 33 and the plug front shell 34 are engaged, the plug positive terminal 31 and the plug negative terminal 32 pass through the sixth through hole 351 and the fifth through hole 343 and engage with the limiting groove 342. The abutment portion 333 abuts against the end of the probe body 361 that passes through the sixth through hole 351 and the fifth through hole 343 and engages between the abutment portion 333 and the sixth through hole 351. The first engaging portion 332 engages with the first engaging portion 341.

[0032] To facilitate understanding of the above structure, its usage is explained below: After the plug bottom shell 33 and plug front shell 34 are engaged, the first engaging part 332 engages with the first engaging part 341. The plug positive terminal 31 and plug negative terminal 32 pass through the third through hole 3311 and the fourth through hole 3312 of the plug bottom shell 33 and engage within the limiting groove 342. At this time, one end of the plug positive terminal 31 and plug negative terminal 32 is fixed within the first space formed by the engagement of the plug bottom shell 33 and plug front shell 34. Then, the fixed plug bottom shell 33 and plug front shell 34 are fitted into the fastening cap 35. The user only needs to tighten the fastening cap 35 onto the first connecting part 212 of the socket housing 21. When it is necessary to replace another detection probe 3, simply unscrew the fastening cap 35, pull out the plug positive terminal 31 and plug negative terminal 32, and replace it with a probe module 3 that includes other probes 36.

[0033] This utility model discloses a thermometer with replaceable connectors. By setting up a conversion socket 2 and a probe module 3, the conversion socket 2 and the probe module 3 can be quickly connected and disconnected. This allows the main body 1 to be quickly assembled and disassembled with different probe modules 3 through the conversion socket 2, expanding the application range, eliminating the need for tools, and reducing the cost of use.

[0034] It is understood that the thermometer with a fastening connection component of this utility model can be used in industrial, food and laboratory fields.

[0035] Example 2 look Figures 7 to 9 , Figure 7This is a two-dimensional front view of the adapter socket for the thermometer with replaceable connectors in Embodiment 2; Figure 8 This is an exploded two-dimensional view of the fastening cap of the thermometer with replaceable connector in Embodiment 2. Figure 9 This is a two-dimensional side view of the fastening cap of the thermometer with replaceable connector in Embodiment 2.

[0036] Compared to Embodiment 1, the only difference in this embodiment is that the fastening cap is nested outside the plug housing 34 and connected to the socket housing 21 in a snap-fit ​​manner. This embodiment uses a snap-fit ​​connection.

[0037] The socket housing is provided with a second connecting portion 218. A resilient engaging piece 2181 is provided on the side end face of the second connecting portion 218. The resilient engaging piece 2181 includes a rising portion 21811 and a descending portion 21812. One end of the rising portion 21811 is connected to the second connecting portion 218, and the rising portion 21811 extends to the other end in a direction away from the second connecting portion 218 and at an acute angle to the second connecting portion 218. One end of the descending portion 21812 is connected to one end of the rising portion 21811 and extends in a direction close to the second connecting portion 218. The fastening cap 35 includes a first closed-loop portion 352, a second closed-loop portion 353, and resilient sealing elements 354 with their two ends respectively fitted onto the first closed-loop portion 352 and the second closed-loop portion 353. The resilient sealing element 354 can be an resilient sealing sleeve. The first closed-loop portion 352 is also provided with a second snap-fit ​​portion 3521. When the first closed-loop portion 352 is fitted onto the second connecting portion 218, the first closed-loop portion 352, the second snap-fit ​​portion 3521, and the elastic locking piece 2181 are snapped together. At this time, the second closed-loop portion 353 abuts against the plug faceplate 34. A second sealing ring is provided between the first closed-loop portion 352 and the second connecting portion 218.

[0038] When assembling the plug housing 34 and the socket housing 21, the two ends of the elastic seal 354 are first fitted onto the first closed loop portion 352 and the second closed loop portion 353. The first closed loop portion 352, the elastic seal 354, and the second closed loop portion 353 together form a tubular space. Then, the assembled elastic seal 35, the first closed loop part 352 and the second closed loop part 353 are sleeved on the second connecting part 218 through the first closed loop part 352. Since the diameter of the first closed loop part 352 is smaller than the radial length of the second connecting part 218 at the elastic engaging piece 2181, it will compress the elastic engaging piece 2181 and shift it inward. When the first closed loop part 352 passes through the rising part 21811, the elastic engaging piece 2181 will rebound back to its original position. When it passes through the falling part 21812, the first closed loop part 352 will engage with the falling part 21812. At this time, the falling part 21812 is also located between the second engaging parts 3521, thereby limiting its six directions. At this time, the elastic seal 354 is in a stretched state, and it exerts a force to pull the second closed loop 353 to the left, thereby causing the second closed loop 353 to abut against the plug bottom shell 33 and the plug face shell 34 to secure the plug positive terminal 31 and the plug negative terminal 32. When it is necessary to replace the probe 36, simply press the elastic seal 354 at the corresponding positions of the rising part 21811 and the falling part 21812, causing the rising part 21811 and the falling part 21812 to move radially inward, and then pull the first closed loop 352 outward to disengage it from the elastic locking piece 2181, thus separating the adapter socket 2 from the probe module 3.

[0039] In this embodiment, the second connecting part 218 is provided with a seventh through hole 3531 at the position corresponding to the elastic locking piece 2181. The seventh through hole 3531 is used to ensure that the displacement of the elastic locking piece 2181 is not obstructed during elastic deformation.

[0040] This utility model discloses a thermometer with replaceable connectors. By setting up a conversion socket 2 and a probe module 3, the conversion socket 2 and the probe module 3 can be quickly connected and disconnected, realizing the rapid assembly and disassembly of the main body 1 with different connectors, expanding the application range, eliminating the need for tools, and reducing the cost of use.

[0041] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
