[0018] In order to better understand the purpose, structure and function of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] Figure 1 The structure of the jumper assembly 100 with a measurement socket according to an embodiment of the present utility model is shown. As Figure 1 shown, the jumper assembly 100 with a measurement socket may include: an upper joint assembly 1 for detachably connecting to the first sub-section, a lower joint assembly 3 for detachably connecting to the second sub-section, and a jumper cable assembly 2 detachably connecting the upper joint assembly 1 and the lower joint assembly 3. Among them, the upper joint assembly 1 may include a male plug base body 11. One end of the male plug base body 11 connected to the first sub-section is hermetically provided with a first multi-core male pin 12 (preferably a 48-core male pin). The other end of the male plug base body 11 is hermetically provided with a first measurement socket 13 (preferably a 48-core female pin). A first jumper male plug 16 (preferably a 48-core male pin) is also hermetically connected to the outer peripheral wall of the male plug base body 11. The first multi-core male pin 12 is electrically connected to the first measurement socket 13 and the first jumper male plug 16 respectively; the lower joint assembly 3 may include a female plug base body 31. One end of the female plug base body 31 connected to the second sub-section is hermetically provided with a second multi-core female pin 32. The other end of the female plug base body 31 is hermetically provided with a second measurement socket 33. A second jumper male plug 34 is also hermetically connected to the outer peripheral wall of the female plug base body 31. The second multi-core female pin 32 (preferably a 48-core female pin) is electrically connected to the second measurement socket 33 (preferably a 48-core female pin) and the second jumper male plug 34 (preferably a 48-core male pin) respectively; the jumper cable assembly 2 may include a jumper cable 21 and jumper female plugs 22 connected to both ends of the jumper cable 21. The jumper female plugs 22 are detachably connected to the first jumper male plug 16 and the second jumper male plug 34 respectively.

[0020] When the jumper assembly 100 with a measurement socket according to an embodiment of the present utility model is working, first connect the first multi-core male pin 12 of the upper joint assembly 1 to the first sub-section, connect the second multi-core female pin 32 of the lower joint assembly 3 to the second sub-section, then connect the two jumper female plugs 22 of the jumper cable assembly 2 to the first jumper male plug 16 and the second jumper male plug 34 respectively, and finally power on the instrument string. Measure the first measurement socket 13 and the second measurement socket 33 with a multimeter or an oscilloscope to collect the corresponding values, so as to be able to quickly and effectively test the connection between the first sub-section and the second sub-section, and thus quickly and accurately identify the faulty sub-section.

[0021] In the cross - connection component 100 with a measurement socket according to the embodiment of the present utility model, the disassembly and assembly of the upper joint component 1, the cross - connection cable component 2, and the lower joint component 3 are flexible and convenient, and the connection range is wider. It is not only more convenient for installation and measurement, but also more convenient for storage. At the same time, the cross - connection cable component 2 is detachably connected to the first cross - connection male plug 16 and the second cross - connection male plug 34 respectively. When a measurement and control failure occurs, the first short section and the second short section can be connected in a soft connection. The first short section and the second short section can be all short sections except the electronic circuit and the hydraulic power short section (which can be realized by the existing cross - connection wire), making up for the defects of the existing cross - connection wire, realizing the acquisition of sectional measurement circuit data. By using a multimeter or an oscilloscope on the first measurement socket 13 and the second measurement socket 33, the circuit data can be measured in real time, and the tested circuit indexes are more real, accurate, and intuitive, so the detection is more efficient.

[0022] In the preferred embodiment as shown in Figure 1 and Figure 2 a positioning pin 14 can axially extend outward on the end face of the first multi - core male pin 12. The positioning pin 14 plays a guiding role to enable the first multi - core male pin 12 to be inserted more accurately into the female head of the first short section.

[0023] Preferably, as shown in Figure 1 and Figure 2 one end of the male plug base body 11 connected to the first short section is detachably connected with a sealing cover 15. The sealing cover 15 is used to protect the first multi - core male pin 12 and the positioning pin 14. Further, the sealing cover 15 and the male plug base body 11 can be threadedly connected.

[0024] According to the present utility model, in the preferred embodiment as shown in Figure 2 the male plug base body 11 may include a first cylinder body 111 and a first branch cylinder body 112 communicating with the outer peripheral wall of the first cylinder body 111. The first multi - core male pin 12 and the first measurement socket 13 are respectively sealed and fixed at both ends of the first cylinder body 111, and the first cross - connection male plug 16 can be sealed and fixed at the free end of the first branch cylinder body 112. This setting realizes the separate fixation of the first multi - core male pin 12, the first measurement socket 13, and the first cross - connection male plug 16. The setting of the first branch cylinder body 112 is more convenient for branching out the first cross - connection male plug 16, thus facilitating the subsequent connection of the first cross - connection male plug 16 and the cross - connection female plug 22.

[0025] Further, as shown in Figure 1 and Figure 2 a first hammer 17 can be formed on the outer peripheral wall of the first cylinder body 111 close to the first measurement socket 13. The first hammer 17 plays a positioning role to prevent damage to the first multi - core male pin 12 when the first multi - core male pin 12 is inserted into the female head of the first short section and warns that the first multi - core male pin 12 has been installed in place.

[0026] In a preferred embodiment as shown in Figure 2 , the first branch cylinder 112 is inclined towards the first measurement socket 13. This setting can, on the one hand, facilitate the quick connection between the first cross-connect male plug 16 and the cross-connect female plug 22 more conveniently, and on the other hand, can reduce the volume occupied by the male plug base 11.

[0027] According to the present utility model, in a preferred embodiment as shown in Figure 1 and Figure 3 , the female plug base 31 may include a second cylinder body 311 and a second branch cylinder 312 communicating with the outer peripheral wall of the second cylinder body 311. The second multi-core female pin 32 and the second measurement socket 33 are respectively sealed and fixed at both ends of the second cylinder body 311, and the second cross-connect male plug 34 is sealed and fixed at the free end of the second branch cylinder 312. This setting realizes the separate fixation of the second multi-core female pin 32, the second measurement socket 33, and the second cross-connect male plug 34. The setting of the second branch cylinder 312 makes it more convenient to branch out the second cross-connect male plug 34, thus facilitating the subsequent connection between the second cross-connect male plug 34 and the cross-connect female plug 22.

[0028] Furthermore, as shown in Figure 1 and Figure 3 , a second ram 35 is formed on the outer peripheral wall of the second cylinder body 311 near the second measurement socket 33; an axial positioning hole 36 is formed on the outer peripheral wall of the second cylinder body 311 far from the second measurement socket 33. The second ram 35 plays a positioning role to prevent damage to the second multi-core female pin 32 when the second multi-core female pin 32 is inserted into the male head of the second short section and warns that the second multi-core female pin 32 is installed in place. The axial positioning hole 36 plays a guiding role for the second multi-core female pin 32 to be able to be more accurately aligned and connected with the male head of the second short section.

[0029] In a preferred embodiment as shown in Figure 3 , the second branch cylinder 312 may be inclined towards the second measurement socket 33. This setting can, on the one hand, facilitate the quick connection between the second cross-connect male plug 34 and the cross-connect female plug 22 more conveniently, and on the other hand, helps to reduce the volume occupied by the female plug base 31.

[0030] According to the present utility model, the male plug base 11 and the female plug base 31 may both be made of aluminum alloy, making them lighter in weight; the bases of the first multi-core male pin 12, the first measurement socket 13, the first cross-connect male plug 16, the second multi-core female pin 32, the second measurement socket 33, the second cross-connect male plug 34, and the cross-connect female plug 22 are all made of polyether ether ketone, ensuring insulation.
