The invention belongs to the field of instrument connection, and discloses a universal positioning interface structure, which comprises a joint, a threaded ring, a plurality of connecting pieces and aplurality of positioning pieces, a threaded ring groove and a plurality of joint positioning holes are formed in the joint, and the threaded ring is detachably connected with the threaded ring groove; a mounting hole is formed in the joint; a plug fixing seat and a plug are arranged in the mounting hole; one end of the plug fixing seat is provided with a plurality of fixing seat positioning holes, and the other end is provided with a plurality of fixing seat limiting holes. A plurality of plug limiting holes are formed in one end of the plug; the fixing base limiting holes and the plug limiting holes are connected in a one-to-one correspondence mode through a plurality of connecting pieces, and the fixing base positioning holes and the connector positioning holes are connected in a one-to-one correspondence mode through a plurality of positioning pieces. The positioning and fixing requirements of the plug are converted to the other end of the joint through the plug fixing seat, and the final positioning and fixing are realized through the positioning piece, so that positioning and fixing of the plug can be met, a sealing link can be omitted, and the structure is easy to disassemble and is suitable for underground high-temperature and high-pressure environments.
Description
technical field [0001] The invention belongs to the field of instrument connection and relates to a general positioning interface structure. Background technique [0002] The connection of common oil well logging instruments usually includes positioning pins on the plug, which are directly fixed to the positioning holes on the instrument shell to realize the fixing and positioning of the plug. However, for small-diameter instruments, the shell of the instrument is very thin, which cannot meet the processing of positioning holes. [0003] At present, general small-diameter instrument interface solutions such as figure 1 As shown, the plug is positioned and connected to the connector through the connector, and the shell and the connector are connected through a threaded ring. This structure is simple and easy to assemble, so it is widely used. However, the interface needs to be sealed at the connection between the joint and the shell. For high-temperature and high-pressure i...
