For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0027] For the convenience of description, Figure 4 As shown in , the direction indicated by x is expressed as upward, and the direction indicated by y is expressed as downward. It should be noted that Figure 4 The positional relationship between the upper mounting plate 11 and the lower mounting plate 12 is only an exemplary illustration, and does not limit the upper mounting plate 11 to be arranged at the top and the lower mounting plate 12 to be arranged at the bottom.

[0028] like Figures 1 to 3 As shown, the fixing structure 1 of the sensor plug of the present application includes an upper mounting plate 11 and a lower mounting plate 12 that are detachably connected. A plurality of sensor plugs can be arranged side by side between the upper mounting plate 11 and the lower mounting plate 12. When the fixing structure 1 is in a closed state, the upper mounting plate 11 and the lower mounting plate 12 are connected and fix the plurality of sensor plugs. The plurality of sensor plugs are arranged side by side and in a certain order between the upper mounting plate 11 and the lower mounting plate 12, so that the plurality of sensor plugs maintain a certain order when being plugged in and unplugged, thereby ensuring the accuracy of the sensor plug connection. The plug-in end of the sensor plug can extend from between the upper mounting plate 11 and the lower mounting plate 12. When multiple sensor plugs are simultaneously inserted into the socket using the fixing structure 1, the extended plug-in end can be directly connected to the socket without being blocked, thereby ensuring that the sensor plug can be smoothly inserted into the socket. When the sensor plug needs to be removed from the socket, the upper mounting plate 11 and the lower mounting plate 12 will not hinder the connection between the plug-in end and the socket when they are connected to the sensor plug. Only after force is applied to the upper mounting plate 11 and the lower mounting plate 12 can the plug-in end of the sensor plug be removed from the socket. The clamping and fixing of the sensor plug by the upper mounting plate 11 and the lower mounting plate 12 can realize the simultaneous plugging and unplugging of multiple sensor plugs, thereby realizing the rapid transfer of the sensor plugs and avoiding the problem of disordered sequence of the sensor plugs. When the fixed structure 1 is in the open state, the sensor plug and the fixed structure 1 are detachable. After the sensor plug is plugged into the socket, the upper mounting plate 11 and the lower mounting plate 12 need to be removed from the sensor plug. At this time, the fixed structure 1 is opened, and the upper mounting plate 11 and the lower mounting plate 12 are separated. The upper mounting plate 11 and the lower mounting plate 12 can be taken out of the sensor plug. The removed upper mounting plate 11 and the lower mounting plate 12 will not affect the connection between the sensor plug and the socket.

[0029] In one embodiment, if Figure 1 , Figure 4 As shown, the upper mounting plate 11 includes a first mounting plate 111, and the lower mounting plate 12 includes a second mounting plate 121. When the fixing structure 1 is in a closed state, the first mounting plate 111 abuts against the second mounting plate 121, and the plug-in end can be fixed by the first mounting plate 111 and the second mounting plate 121. When the fixing structure 1 is in a closed state, the sensor plug is directly fixed by the first mounting plate 111 and the second mounting plate 121, thereby preventing the sensor plug from shaking between the first mounting plate 111 and the second mounting plate 121.

[0030] It should be noted that the fixing structure 1 can fix the sensor plug by fixing the plug-in end of the sensor plug through the first mounting plate 111 and the second mounting plate 121. Of course, the fixing structure 1 can also fix the sensor plug by fixing other parts of the sensor plug, for example, by clamping the main body of the sensor plug to fix the sensor plug, wherein one end of the main body is connected to the plug-in end, and the other end is connected to the pipeline. The above is not restrictive and can be set according to the needs of technical personnel in this field.

[0031] In one embodiment, if Figure 1 , Figure 4 As shown, a first mounting channel 1111 is provided in the first mounting plate 111, and a second mounting channel 1211 is provided in the second mounting plate 121. The first mounting channel 1111 is communicated with the second mounting channel 1211, and the plug-in end can be fixed in the first mounting channel 1111 and the second mounting channel 1211, and can extend out of the first mounting channel 1111 and the second mounting channel 1211. In general, the plug-in end of each sensor plug includes two plug connectors, and the two plug connectors can be respectively inserted into the two jacks of the corresponding socket. When the fixing structure 1 is needed to plug and unplug the sensor plug, the two plug connectors of the sensor plug are respectively extended into the first mounting channel 1111 and the second mounting channel 1211, and the two plug connectors are respectively extended vertically from the corresponding first mounting channel 1111 and the second mounting channel 1211, so that the extended plug connector can be smoothly plugged into the socket. The above-mentioned first mounting channel 1111 and the second mounting channel 1211 can not only fix the sensor plug, but also ensure that the sensor plug can be inserted into the socket, which facilitates the transfer of the sensor plug.

[0032] In one embodiment, if Figure 3 , Figure 4 As shown, the first mounting plate 111 includes a first inclined surface 1112, and the cross section of the first mounting plate 111 at the first inclined surface 1112 gradually decreases from one end of the first inclined surface 1112 to the other end of the first inclined surface 1112. The second mounting plate 121 includes a second inclined surface 1212, and the cross section of the second mounting plate 121 at the second inclined surface 1212 gradually decreases from one end of the second inclined surface 1212 to the other end of the second inclined surface 1212. When the fixing structure 1 is in a closed state, the other end of the first inclined surface 1112 abuts against the other end of the second inclined surface 1212, as shown in FIG. Figure 3As shown, at this time, one end of the first mounting plate 111 where the smallest cross-section is located is abutted against one end of the second mounting plate 121 where the smallest cross-section is located. When the first mounting plate 111 is connected to the second mounting plate 121, the two plug connectors can quickly enter the first mounting channel 1111 from one end of the smallest cross-section of the first mounting plate 111 and enter the second mounting channel 1211 from one end of the smallest cross-section of the second mounting plate 121. When the first mounting plate 111 and the second mounting plate 121 are removed from the sensor plug, the first mounting plate 111 and the second mounting plate 121 connected by the smallest cross-section can be quickly separated, so that the plug connector of the sensor plug can be quickly pulled out of the first mounting channel 1111 and the second mounting channel 1211. Therefore, the setting of the first inclined surface 1112 and the second inclined surface 1212 enables the sensor plug to be quickly disassembled and assembled from the first mounting plate 111 and the second mounting plate 121.

[0033] In one embodiment, if Figure 3 , Figure 4 As shown, the upper mounting plate 11 further includes a first guide structure, and the lower mounting plate 12 further includes a second guide structure, and the first guide structure cooperates with the second guide structure to make the first mounting plate 111 abut against the second mounting plate 121. Through the cooperation of the first guide structure and the second guide structure, the upper mounting plate 11 and the lower mounting plate 12 can be accurately connected according to the guidance of the first guide structure and the second guide structure, thereby avoiding the problem of installation misalignment between the upper mounting plate 11 and the lower mounting plate 12.

[0034] In one embodiment, if Figure 3 , Figure 4 As shown, the first guide structure is set to one of the guide column 122 or the guide hole 112, and the second guide structure is set to the other of the guide column 122 or the guide hole 112. For the convenience of introduction, the first guide structure is the guide hole 112, and the second guide structure is the guide column 122. For example, the guide hole 112 is set on the upper mounting plate 11, and the guide column 122 is set on the lower mounting plate 12. The guide column 122 can extend into the guide hole 112. When the upper mounting plate 11 is installed on the lower mounting plate 12, the guide hole 112 is aligned with the guide column 122 and moves along the height direction of the guide column 122. The guide hole 112 can move along the height direction of the guide column 122 to a first position 122a and a second position 122b. At the first position 122a, as shown in FIG. Figure 3 As shown, the guide hole 112 cannot move further after it moves into position, the upper mounting plate 11 is connected to the lower mounting plate 12, the first mounting plate 111 abuts against the second mounting plate 121, and the sensor plug can be fixed between the first mounting plate 111 and the second mounting plate 121, at the second position 122b, as shown in FIG. Figure 4As shown, the first mounting plate 111 is separated from the second mounting plate 121, and the sensor plug can be removed from between the first mounting plate 111 and the second mounting plate 121. The guide hole 112 and the guide column 122 have a simple structure and can guide the connection between the first mounting plate 111 and the second mounting plate 121, further avoiding the problem of misalignment of the first mounting plate 111 and the second mounting plate 121.

[0035] In one embodiment, if Figure 3 , Figure 4 , Figure 5 As shown, the cross section of the guide column 122 perpendicular to the height direction of the guide column 122 is a polygon. Figure 3-5 Taking the positive direction as an example, the shape of the guide hole 112 is a polygon that matches the cross-section of the guide column 122. The guide column 122 and the guide hole 112 cooperate with each other through the polygon to avoid relative rotation during the movement of the upper mounting plate 11 and the lower mounting plate 12, thereby further ensuring the accuracy of the guide column 122 and the guide hole 112 in guiding the first mounting plate 111 and the second mounting plate 121.

[0036] In one embodiment, if Figure 3 , Figure 4 As shown, a limiting plate 1221 is provided at the first end of the guide column 122, and the cross-sectional dimension of the limiting plate 1221 is larger than the cross-sectional dimension of the guide hole 112, so that at the second position 122b, the limiting hole abuts against the limiting plate 1221. Due to the limiting of the limiting plate 1221, when the upper mounting plate 11 and the lower mounting plate 12 are separated from the sensor plug, the upper mounting plate 11 will not fall off from the lower mounting plate 12, thereby avoiding the problem of parts loss after the fixing structure 1 is disassembled. In addition, when reinstalling on the sensor plug, there is no need to re-guide the guide column 122 and the guide hole 112, thereby saving installation steps and time.

[0037] In one embodiment, if Figure 5 As shown, the upper mounting plate 11 is provided with a first magnet 113, and the lower mounting plate 12 is provided with a second magnet 123. When the fixed structure 1 is in a closed state, the first magnet 113 and the second magnet 123 are attracted to each other, and the upper mounting plate 11 and the lower mounting plate 12 are connected by magnetic attraction, which can be convenient for disassembly and assembly. Of course, the upper mounting plate 11 and the lower mounting plate 12 can also be connected by other methods, such as snap-on. The above is not restrictive and can be set according to the needs of technical personnel in this field. The above are all within the protection scope of this application.

[0038] In one embodiment, if Figure 5As shown, at least one of the upper mounting plate 11 and the lower mounting plate 12 is provided with a third magnet 124. Taking the third magnet 124 provided on the lower mounting plate 12 as an example, since the sensor plug is connected to the test prototype, the same prototype needs to be tested in multiple ambient temperature chambers. When the sensor plug is removed from the socket through the fixed structure 1, the sensor plug needs to be set at a certain position of the prototype so that the sensor plug can be re-inserted into the corresponding socket after the chamber is turned. The third magnet 124 provided on the lower mounting plate 12 can make the fixed structure 1 magnetically attracted to the outer surface of the prototype through the third magnet 124. At this time, the fixed structure 1 is equivalent to the mounting frame of the sensor plug. When the sensor plug needs to be plugged into the socket, the fixed structure 1 is removed from the outer surface of the prototype. The provision of the third magnet 124 facilitates the placement of the sensor plug, so that there is no need to set an additional placement position of the sensor plug on the prototype.

[0039] In one embodiment, if Figure 3 , Figure 4 , Figure 5 As shown, the upper mounting plate 11 further includes a third mounting plate 114, and a first groove 1141 is provided at one end of the third mounting plate 114 close to the lower mounting plate 12. The lower mounting plate 12 further includes a fourth mounting plate 125, and a second groove 1251 is provided at one end of the fourth mounting plate 125 close to the upper mounting plate 11. When the fixing structure 1 is in a closed state, the third mounting plate 114 and the fourth mounting plate 125 abut against each other, so that the first groove 1141 and the second groove 1251 cooperate to enclose a threading hole 127. When the sensor plug is fixed by the first mounting plate 111 and the second mounting plate 121, the pipeline of the sensor plug can pass through the threading hole 127. The threading hole 127 can organize the pipeline of the sensor plug to avoid problems such as pipeline entanglement.

[0040] In one embodiment, if Figure 4 , Figure 5As shown, the upper mounting plate 11 also includes an upper top plate 115, and the lower mounting plate 12 also includes a lower bottom plate 126. The first mounting plate 111 and the third mounting plate 114 are fixed to the upper top plate 115, and the second mounting plate 121 and the fourth mounting plate 125 are fixed to the lower bottom plate 126. The first mounting plate 111 is arranged in parallel with the third mounting plate 114, and the second mounting plate 121 is arranged in parallel with the fourth mounting plate 125. Since the first mounting plate 111 is connected to the second mounting plate 121, and the third mounting plate 114 is connected to the fourth mounting plate 125, the upper top plate 115, the first mounting plate 111, the second mounting plate 121, the lower bottom plate 126, the third mounting plate 114 and the fourth mounting plate 125 jointly enclose a cavity in which a sensor plug can be placed. When the sensor plug is placed in the cavity, it can be avoided that the sensor plug is touched during the transfer process, thereby ensuring that multiple sensor plugs can be relatively still, and then ensuring that each sensor plug can be simultaneously and accurately plugged into the socket. In addition, the arrangement of the upper top plate 115 and the lower bottom plate 126 can also facilitate the user to apply force to the fixing structure 1, thereby saving more effort when plugging in or removing the sensor plug.

[0041] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
