Description

Technical Field

[0001] The utility model relates to the technical field of signal line connectors, in particular to a well logging signal line connector. Background Art

[0002] Traditional induction logging systems often use analog circuits or a combination of a processor and a dedicated chip as the signal source to output sinusoidal signals. However, these designs present a series of problems in practical applications. First, due to the inherent limitations of analog circuits, their output frequencies often struggle to reach high frequencies, limiting the detection frequency range and resolution of induction logging to a certain extent. This is due to the poor stability of analog circuits. Due to the poor stability of analog circuits, they are easily affected by external factors such as ambient temperature and humidity, resulting in signal distortion, especially in the signal line connector. When the distance between the two groups of signal sources is not long enough, two cables need to be connected to capture the signal. The existing connection method is to connect the connector and the cable, and then use tape to wrap several turns between the connector and the cable to seal both ends of the connector to prevent moisture from returning between the cables and affecting the signal. However, in this way, the connection structure between the cables has no heat dissipation part. After the wire harnesses between the cables are connected, the resistance increases and it is easier to generate heat during the transmission of the electrical signal. As a result, the connecting cables heat up on the connecting connector, which affects the fastening effect of the tape glue. In long-term use, the sealing will be loose, and the signal line core is directly interfered with by the outside world at the joint, making the input and output waveforms of the two lines unequal, thereby causing signal distortion.

After one end of the rotating handle 6 contacts the top of the wedge block 7, a Sliding, when the signal line 3 end is spliced, by manually rotating any one of the sub-sleeve 1 and the female sleeve 2, the splicing operation can be completed when the external thread extension end 401 of the sub-sleeve 1 and the other side of the internal thread extension end 13 of the female sleeve 2, the sub-sleeve 1 and the female sleeve 2 form a sealed environment inside. Then, by manually rotating the first thread cover 4 and the second thread cover 5, they are rotated in the direction of back to back along the outer ring of the sub-sleeve 1 and the female sleeve 2 respectively. During this process, the rotating handle 6 moves axially on the sub-sleeve 1 or the female sleeve 2, so that one end of the rotating handle 6 and the wedge 7 Contact, thereby causing the wedge block 7 to sink on the sub-sleeve 1 or the mother sleeve 2, and move toward the axis of the sub-sleeve 1 or the mother sleeve 2. During the movement of the wedge block 7, the connecting rod can be lowered. When the connecting rod is lowered, the signal line 3 is clamped by the bent clamp 10 located inside the sub-sleeve 1 or the mother sleeve 2, thereby creating a connection between the signal line 3 and the sub-sleeve 1 and the mother sleeve 2. At the same time, multiple bent clamps 10 can seal the entrance of the sub-sleeve 1 and the mother sleeve 2 to prevent moisture from entering and causing disorder to the electrical signal, thereby improving the test quality of the equipment test.

[0022] Specifically, there are at least four bending clips 10, and each bending clip 10 is crescent-shaped. Multiple bending clips 10 are stacked and staggered together.
