[0042] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0044] like Figure 1 As shown, the thermocouple plug 10 provided in the embodiment of the present disclosure includes: a base 100, a terminal 200, a plug rod 300 and a slide cover 400. A slide groove 110 is provided on the base 100. The terminal 200 is arranged on the base 100. The plug rod 300 is arranged on the base 100 and is correspondingly connected to the terminal 200. The slide cover 400 includes a sliding portion, which is arranged in the slide groove 110, so that the slide cover 400 can slide relative to the base 100 to achieve switching between a closed state and an open state between the slide cover 400 and the base 100. Among them, when the slide cover 400 and the base 100 are in a closed state, the slide cover 400 can completely cover the terminal 200, and when the slide cover 400 and the base 100 are in an open state, the slide cover 400 can completely expose the terminal 200.

[0045] Specifically, the thermocouple plug 10 is an accessory for connecting a thermocouple to a measuring instrument, and has the characteristics of high precision, high stability and high reliability. According to different interfaces, the thermocouple plug 10 can be divided into a pin type and a socket type. According to different shapes, the thermocouple plug can be divided into a T-type, an L-type, etc. In different use environments, the thermocouple plug 10 can also be made of different materials, such as copper, chromium, nickel and aluminum, etc., to adapt to different temperature ranges and application occasions.

[0046] Specifically, the thermocouple plug 10 includes a base 100, a terminal block 200, a plug rod 300, and a sliding cover 400. The terminal block 200 and the plug rod 300 are both disposed on the base 100, and the terminal block 200 needs to be connected to the plug rod 300 and an external sensor so that the data detected by the sensor line can be transmitted through the plug rod 300 to the thermocouple socket into which the plug rod 300 is inserted.

[0047] It can be understood that there are multiple connection terminals 200 and insertion rods 300, and the connection terminals 200 and the insertion rods 300 correspond one to one.

[0048] Specifically, since temperature data needs to be detected through multiple sensing wires, the number of sensing wires is usually multiple. The wiring terminal 200 is used to connect with external sensing wires, and the number of the wiring terminal 200 corresponds to the number of the plug rods 300. Therefore, multiple wiring terminals 200 and plug rods 300 need to be provided.

[0049] Exemplarily, the number of the connection terminals 200 and the insertion rods 300 is 2 or 3.

[0050] Specifically, by providing a slide groove 110 on the base 100, providing a sliding portion on the slide cover 400, and providing the sliding portion in the slide groove 110, the slide cover 400 can slide along the slide groove 110 relative to the base 100, thereby realizing the switching between the closed state and the open state between the slide cover 400 and the base 100. The closed state is a state in which the slide cover 400 can completely cover the connection terminal 200, and the open state is a state in which the slide cover 400 can completely expose the connection terminal 200.

[0051] For example, when the sliding cover 400 and the base 100 are in an open state, Figure 1 As shown, the situation when the sliding cover 400 and the base 100 are in a closed state is as follows Figure 2 shown.

[0052] Optionally, the slide groove 110 is opened on the side of the base 100 along the extending direction of the insertion rod 300 .

[0053] In the related art, thermocouple plugs are usually used in temperature tests such as freezing capacity tests and cooling tests on refrigerator prototypes or freezer prototypes. During the temperature test, the risk of thermocouple failures such as short circuits is high. The base and sliding cover of the existing thermocouple plug are connected by screws. When troubleshooting short circuits and other faults on the thermocouple plug, it is necessary to unplug the thermocouple plug and unscrew the screws connecting the base and the sliding cover to expose the wiring terminals, which makes it very inconvenient to troubleshoot short circuits and other faults of the thermocouple plug.

[0054] Therefore, in the embodiment of the present disclosure, a slide groove 110 is provided on the base 100 of the thermocouple plug 10, a sliding part is provided on the slide cover 400, and the sliding part is provided in the slide groove 110, so that the slide cover 400 can slide along the slide groove 110 relative to the base 100, and realize the switching between the closed state (the slide cover 400 can completely cover the wiring terminal 200) and the open state (the slide cover 400 can completely expose the wiring terminal 200) between the slide cover 400 and the base 100. In this way, it is possible to observe whether the sensing wires are in contact, whether the sensing wires and the wiring terminal 200 are short-circuited or disconnected, and the thermocouple plug 10 can be troubleshooted and repaired only by sliding the slide cover 400. The convenience of troubleshooting the thermocouple plug 10 is improved, and the difficulty of troubleshooting the thermocouple plug 10 is reduced.

[0055] In some embodiments, the connection terminal 200 is a press-type connection terminal 200 .

[0056] Specifically, by setting the connection terminal 200 of the thermocouple plug 10 as a press-type connection terminal 200 , the sensing line can be connected to the connection terminal 200 or disconnected from the connection terminal 200 only by pressing the connection terminal 200 .

[0057] For example, when checking whether the thermocouple plug 10 has a disconnection fault and the sensing wire needs to be disconnected from the terminal block 200, it is not necessary to unscrew the connecting screw on the terminal block and unwind the sensing wire wound around the connecting screw as in the related art. The sensing wire can be removed from the terminal block 200 by pressing the terminal block 200, so that the sensing wire is disconnected from the terminal block 200.

[0058] For example, when a short circuit fault is detected in the thermocouple plug 10 and the sensing wire needs to be reconnected to the terminal 200, it is not necessary to unscrew the connecting screw on the terminal, wrap the sensing wire around the connecting screw, and screw the connecting screw back to the terminal 200 as in the related art. The sensing wire can be connected to the terminal 200 by simply pressing the terminal 200, inserting the sensing wire to the corresponding position, and then releasing the pressed part.

[0059] In the embodiment of the present disclosure, by setting the connection terminal 200 of the thermocouple plug 10 as a press-type connection terminal 200, the process of disconnecting the connection terminal 200 from the sensing line and connecting the connection terminal 200 to the sensing line is simplified. This is conducive to further improving the convenience of troubleshooting the thermocouple plug 10.

[0060] like Figure 3 As shown, in some embodiments, the terminal block 200 includes: a housing 210, a spring 220 and a pressing plate 230. The housing 210 includes a receiving cavity. The spring 220 is disposed in the receiving cavity, and the spring 220 is connected to the insertion rod 300. The pressing plate 230 is disposed on the upper part of the housing 210, and when the pressing plate 230 is pressed, the distance between the pressing plate 230 and the spring 220 increases.

[0061] Specifically, a spring piece 220 connected to the insertion rod 300 is arranged in the accommodating cavity formed by the housing 210, and a pressing plate 230 is arranged on the upper part of the housing 210. Figure 3 When the pressing plate 230 is pressed in the direction A shown in FIG, the distance between the pressing plate 230 and the spring sheet 220 will be increased. In this way, a sensing line can be placed between the pressing plate 230 and the spring sheet 220, or a sensing line can be taken out from between the pressing plate 230 and the spring sheet 220.

[0062] For example, when the sensing wire needs to be connected to the terminal block 200, it is not necessary to unscrew the connecting screw on the terminal block, wrap the sensing wire around the connecting screw, and then screw the connecting screw back to the terminal block as in the related art. Figure 3Press the pressing plate 230 in the direction A shown in the figure, insert the sensor line between the pressing plate 230 and the spring 220, and then release the pressing plate to complete the connection between the sensor line and the wiring terminal 200.

[0063] For example, when the sensing wire needs to be disconnected from the wiring terminal 200, it is not necessary to unscrew the connecting screws on the wiring terminal and unwind the connecting screws of the sensing wire as in the related art. Figure 3 The pressing plate 230 is pressed in the direction A shown in the figure, and the sensing line is taken out from between the pressing plate 230 and the spring 220, so that the sensing line can be disconnected from the connecting terminal 200.

[0064] In the disclosed embodiment, the wiring terminal 200 composed of the housing 210, the spring 220 and the pressing plate 230 is adopted, which simplifies the process of disconnecting the wiring terminal 200 from the sensing line and connecting the wiring terminal 200 to the sensing line. This is conducive to further improving the convenience of troubleshooting the thermocouple plug 10.

[0065] like Figure 4 As shown, in some embodiments, the top of the base 100 is stepped, including a first step surface and a second step surface, and the first step surface is higher than the second step surface; wherein the terminal 200 is arranged on the second step surface, and the end of the insertion rod 300 connected to the terminal 200 is located at the lower part of the second step surface, and the slide groove 110 is arranged on the side of the part of the base 100 corresponding to the second step surface. When the sliding cover 400 and the base 100 are in a closed state, the sliding cover 400 is docked with the second step surface so as to completely cover the second step surface.

[0066] It should be noted that Figure 4 The plane indicated by B is the first step surface, the plane indicated by C is the second step surface, and the plane indicated by D is the connecting surface of the first step surface B and the second step surface C. The connecting surface D is perpendicular to the first step surface B and the second step surface C.

[0067] Specifically, when the slide cover 400 and the base 100 are in a closed state, the end surface of the opening side of the slide cover 400 abuts against the connection surface D.

[0068] Specifically, by setting the top of the base 100 to be stepped and setting the slide groove 110 on the side of the base 100 corresponding to the second step surface, when the sliding cover 400 and the base 100 are in a closed state, a cavity can be formed between the sliding cover 400 and the second step surface to protect the terminal 200.

[0069] like Figure 5As shown, in some embodiments, the thermocouple plug 10 further includes a stopper 120 . The stopper 120 is disposed in the slide groove 110 to prevent the sliding portion of the slide cover 400 from sliding out of the slide groove 110 .

[0070] Specifically, by providing the stopper 120 in the slide groove 110 of the base 100, after the slide cover 400 and the slide groove 110 are in the open state, the stopper 120 can prevent the sliding part of the slide cover 400 from continuing to slide down along the slide groove 110. In this way, it can be avoided that the sliding part of the slide cover 400 completely slides out of the slide groove 110, resulting in the need to reassemble the slide cover 400 and the base 100.

[0071] In the disclosed embodiment, the stopper 120 is provided in the slide groove 110 of the base 100 to prevent the sliding portion of the slide cover 400 from sliding out of the slide groove 110. This reduces the risk of the slide cover 400 being completely separated from the base 100 when troubleshooting a short circuit or other fault on the thermocouple plug 10, and the slide cover 400 and the base 100 need to be reassembled after the troubleshooting.

[0072] like Figure 6 As shown, in some embodiments, the thermocouple plug 10 further includes a locking member 130. The locking member 130 is used to lock the sliding cover 400 and the base 100 when the sliding cover 400 and the base 100 are in a closed state; the locking member 130 includes a locking portion 131 and a matching portion 132, wherein the locking portion 131 is disposed on one of the sliding cover 400 and the base 100, and the matching portion 132 is disposed on the other of the sliding cover 400 and the base 100.

[0073] Specifically, the locking member 130 is provided, and the locking portion 131 of the locking member 130 is provided at one of the sliding cover 400 and the base 100, and the matching portion 132 of the locking member 130 is provided at the other of the sliding cover 400 and the base 100. After the sliding cover 400 is controlled to slide in the slide groove 110 of the base 100, so that the sliding cover 400 and the base 100 are in a closed state, the locking portion 131 will be clamped in the matching portion 132, so that the sliding cover 400 and the base 100 are locked. In this way, the risk of the sliding cover 400 sliding along the base 100 at will and leaking structures such as the connection terminal 200 is reduced.

[0074] Specifically, the locking portion 131 is arranged on one of the slide cover 400 and the base 100, and the matching portion 132 is arranged on the other of the slide cover 400 and the base 100, which means that when the locking portion 131 is arranged on the slide cover 400, the matching portion 132 is arranged on the base 100; when the locking portion 131 is arranged on the base 100, the matching portion 132 is arranged on the slide cover 400. Figure 6The figure shows that the locking portion 131 is disposed on the base 100 and the matching portion 132 is disposed on the sliding cover 400 .

[0075] Exemplarily, the locking portion 131 may be disposed at Figure 4 Referring to the connection surface D shown in FIG. 1 , the matching portion 132 is disposed on the end surface of the opening side of the sliding cover 400 .

[0076] In the embodiment of the present disclosure, a locking portion 131 is provided in one of the sliding cover 400 and the base 100, and a matching portion 132 is provided in the other of the sliding cover 400 and the base 100. When the sliding cover 400 and the base 100 are in a closed state, the sliding cover 400 and the base 100 can be locked. In this way, when the thermocouple plug 10 is not troubleshooting, the sliding cover 400 can be prevented from sliding along the base 100 at will to leak out the wiring terminal 200 and other structures, thereby affecting the normal operation of the thermocouple plug 10.

[0077] like Figure 7 As shown, in some embodiments, the thermocouple plug 10 further includes a clamping member 140. The clamping member 140 is disposed on the base 100, and the clamping member 140 can slide relative to the base 100. The clamping member 140 is used to prevent the sliding cover 400 from sliding relative to the base 100 when the sliding cover 400 and the base 100 are in a closed state.

[0078] Specifically, by providing the clamping member 140, and slidably arranging the clamping member 140 on the base 100, after the slide cover 400 and the base 100 are in a closed state, the clamping member 140 can be controlled to slide relative to the base 100 to prevent the slide cover 400 from continuing to slide along the slide groove 110. In this way, the risk of the slide cover 400 sliding along the base 100 at will and leaking structures such as the connection terminal 200 is reduced.

[0079] In the embodiment of the present disclosure, a clamping member 140 that can slide along the base 100 is provided. When the slide cover 400 and the base 100 are in a closed state, the slide cover 400 can be restricted in a closed state by preventing the slide cover 400 from continuing to slide along the slide groove 110. In this way, when the thermocouple plug 10 is not troubleshooting, the slide cover 400 can be prevented from sliding along the base 100 at will to leak out the connection terminal 200 and other structures, thereby affecting the normal operation of the thermocouple plug 10.

[0080] like Figure 6 As shown, in some embodiments, the thermocouple plug 10 further includes a branching assembly 150. The branching assembly 150 is arranged corresponding to the wiring terminals 200, and the branching assembly 150 is used to separate the sensor wires connected to different wiring terminals 200.

[0081] Optionally, the branching assembly 150 can be disposed on the sliding cover 400 alone, can be disposed on the base 100 alone, or can be disposed partially on the sliding cover 400 and partially on the base 100. The embodiment of the present disclosure does not specifically limit the location of the branching assembly 150 in the thermocouple plug 10.

[0082] Specifically, when the branching assembly 150 is separately disposed on the base 100, the branching assembly 150 is disposed on Figure 4 The second step surface C of the base 100 shown in FIG. Specifically, since the temperature data needs to be detected through multiple sensing wires, the number of sensing wires is usually multiple. When the temperature data is obtained through the sensing wires, if there is a short circuit between the multiple sensing wires, interference will occur, resulting in low accuracy of the obtained temperature data.

[0083] Therefore, in the embodiment of the present disclosure, a line splitter assembly 150 is provided to separate the sensing lines connected to different wiring terminals 200. In this way, there is a gap between the sensing lines, reducing the risk of short circuit between the two sensing lines.

[0084] like Figure 6 As shown, in some embodiments, the wire splitting assembly 150 includes: a first wire splitting groove 151 and a second wire splitting groove 152. The first wire splitting groove 151 is provided on the sliding cover 400. The second wire splitting groove 152 is provided on the base 100. When the sliding cover 400 and the base 100 are in a closed state, the first wire splitting groove 151 and the second wire splitting groove 152 constitute a wire splitting channel.

[0085] Specifically, the second branching slot 152 is specifically arranged at Figure 4 The second step surface C of the base 100 is shown in FIG.

[0086] Specifically, by setting part of the wire splitting assembly 150 (i.e., the first wire splitting groove 151) on the sliding cover 400 and setting another part of the wire splitting assembly 150 (i.e., the second wire splitting groove 152) on the base 100, when the sliding cover 400 and the base 100 are in a closed state, the first wire splitting groove 151 and the second wire splitting groove 152 can form a wire splitting channel. In this way, the spacing effect of multiple sensor wires can be improved.

[0087] Specifically, by dividing the wire splitting assembly 150 into the first wire splitting groove 151 and the second wire splitting groove 152, when connecting the sensor wire to the wiring terminal 200, it is not necessary to insert the sensor wire into the wire splitting channel, but only to press the sensor wire into the second wire splitting groove 152. In this way, the convenience of connecting the sensor wire to the wiring terminal 200 is improved.

[0088] In the embodiment of the present disclosure, the wire splitting assembly 150 is divided into a first wire splitting groove 151 and a second wire splitting groove 152, the first wire splitting groove 151 is arranged on the sliding cover 400, and the second wire splitting groove 152 is arranged on the base 100.
