The cable line connected with the joint is easy to break, the joint is easy to wear, and the joint is easy to be damp and oxidized, which affects the reliability of the connection between the probe line and the electric method instrument. As a result, the electric connection is often disconnected, which causes problems such as unqualified data collection and difficult troubleshooting, and thus causes rework, which cannot guarantee the progress of field construction, affects the construction efficiency, and increases the construction cost.

[0021] The present invention will be further described in detail below with reference to embodiments:

[0022] A connection device with shielding and protection functions is provided, which is installed between the electrical resistivity meter 1 and the cable. This device not only provides protection for the electrical resistivity meter 1, but also for the aviation connector and the cable connected to the aviation connector. Figures 1-2 As shown, it includes a connector 3, one side of which is connected to the electrical resistivity meter 1, and the other side is connected to a cable via an aviation plug.

[0023] like Figure 1 and Figure 2 As shown, the connector 3 is equipped with electrodes that connect to the electrical resistivity meter 1. Each electrode includes a positive terminal 3-5 and a negative terminal 3-6. The positive terminal 3-5 is connected to the positive terminal of the electrical resistivity meter 1, and the negative terminal 3-6 is connected to the negative terminal of the electrical resistivity meter 1. The electrodes ensure a reliable connection between the electrical resistivity meter 1 and the connector 3.

[0024] The electrode is connected to a wire 3-3 located inside the connector 3. The other end of the wire 3-3 is connected to a cable. The wire 3-3 smoothly connects the electrical transducer 1 on both sides of the connector 3 to the cable, ensuring smooth data acquisition. Therefore, the entire device is reliably connected, effectively avoiding the occurrence of intermittent electrical connections. It also provides some protection for the wire 3-3 located inside the connector 3, the aviation plug connected to the wire 3-3, and the cable connected to the aviation plug.

[0025] like Figure 2 As shown, the conductor 3-3 is disposed within the shielding layer 3-7, which surrounds the interior of the connector 3. One side of the shielding layer 3-7 is connected to the shielding interface of the electrical resistivity meter 1, and the other side is connected to the shielding wire disposed within the cable. The shielding layer 3-7 connects the electrical resistivity meters 1 on both sides to the shielding wire of the cable, ensuring the integrity of the shielding of the conductor 3-3 and the electrical resistivity meters 1 and cable connected to the conductor 3-3. The shielding layer 3-7 is composed of multiple layers of shielding material, which is a high-permeability metallic shielding material. It can effectively shield low-frequency magnetic field interference and block high-frequency electromagnetic interference, providing all-round shielding against low-frequency and high-frequency electromagnetic interference. This greatly improves the anti-interference capability of the electrical resistivity meter and ensures the accuracy and stability of the measurement data.

[0026] The shielding layer 3-7 is connected with the shielding interface of the electrical method instrument 1 through the connecting end 3-4 connected therewith. The arrangement of the connecting end 3-4 ensures the effective connection of the shielding layer 3-7 with the electrical method instrument 1, and ensures the shielding effect of the shielding layer 3-7.

[0027] The cable is connected with the wire 3-3 through the aviation plug, and the connecting end of the wire 3-3 connected with the cable is arranged in the jack 3-2. The jack 3-2 is arranged in correspondence with the aviation plug. The shape of the jack 3-2 corresponds to the aviation plug, and the depth of the jack 3-2 is much greater than the length of the aviation plug. After the aviation plug is matched with the jack 3-2, the aviation plug and the cable connected with the aviation plug are all inserted into the jack 3-2, so that the aviation plug and the cable connected with the aviation plug are prevented from being affected by moisture, oxidation and corrosion in a complex environment. At this time, the shielding wire in the cable is connected with the shielding layer 3-7 in the connecting body 3. The jack 3-2 is arranged at the lower right of the connecting body 3, so as to facilitate the connection of the cable with the connecting body 3. While ensuring the shielding effect of the device, the cable connected with the aviation plug is also protected to a certain extent.

[0028] As shown in Figure 2 The shielding layer 3-7 is provided with a filler 3-8 for accommodating the wire 3-3. The filler 3-8 is a sponge with buffering effect, which can reduce the external force impact on the wire 3-3 during work. The filler 3-8 supports the shielding layer 3-7 to a certain extent, is filled in the shielding layer 3-7, and fixes and protects the positive electrode connector 3-5 connected with the positive electrode of the electrical method instrument 1 and the negative electrode connector 3-6 connected with the negative electrode of the electrical method instrument 1. The filler 3-8 can also fix the wire 3-3 arranged inside the shielding layer 3-7 and connecting the electrical method instrument 1 and the cable together. The wire 3-3 can be fixed with the filler 3-8 through the wire fixing clamp, so as to prevent the wire 3-3 from shaking randomly in the connecting body 3 during work.

[0029] As shown in Figure 2 The connecting body 3 outside the shielding layer 3-7 is provided with a rubber protective layer 3-1, and the outer surface of the rubber protective layer 3-1 is provided with a waterproof layer. The rubber protective layer 3-1 is a conductive rubber shielding layer, which not only has a shielding effect, but also has a certain buffering and sealing performance. Therefore, the arrangement of the rubber protective layer 3-1 and the waterproof layer effectively shields, seals and protects the connecting body 3, and effectively protects the aviation plug connected with the connecting body 3 and the cable connected with the aviation plug, so as to avoid the erosion of the cable and the aviation plug connected with the cable by external force, moisture and humidity, effectively prolong the service life of the cable and the connecting body 3, and improve the reliability of the connection.

[0030] As shown in Figure 1As shown, the connecting body 3 is provided with a cover 2 movably connected therewith. The cover 2 is arranged to shield and protect, facilitate the installation and dismounting of the wire 3-3 in the connecting body 3, and facilitate the maintenance and repair of the connecting body 3, and facilitate the on-site operation. When the wire 3-3 needs to be replaced or the interior of the connecting body 3 needs to be maintained, the cover 2 is only opened for repair, and the wire 3-3 can be conveniently dismounted, facilitating the replacement or maintenance work.

[0031] Finally, it should be noted that: the above examples are only for the purpose of clearly illustrating the utility model, and by no means limit the implementation. For those skilled in the art, on the basis of the above description, other different forms of changes or variations can be made, and all the implementation ways cannot be exhausted here, and the obvious changes or variations derived therefrom still belong to the protection scope of the utility model.
