Among them, the plug body 21 and the socket body 11 in the 19-core connector are installed in the plug shell 22 and the socket shell 12. This connection method is tight, the data transmission is stable, and it is easy to install and disassemble, which is suitable for the quick connection of logging instruments.

[0024] See also Figure 4As shown, specifically, the socket 1 is a socket body 11 and a socket shell 12. The socket body 11 is a cylindrical or prism member made of hard plastic, and 19 sockets are opened on its connecting surface. Among the 19 sockets, one socket is opened at the center position of the connecting surface, and 6 sockets are arranged in a regular hexagon around the socket at the center position. In the prior art, the outermost layer of the center socket has 12 sockets arranged in a regular hexagon, and the 12 sockets can be symmetrical about 6 directions. In order to prevent the problem of mis-insertion of the pins and sockets in the 19-core connector during the connection process, the positions of any number and any position of the anti-mis-insertion sockets in the outermost 12 sockets on the socket body 11 can be changed, as long as it is ensured that the 19-core connector will not have the problem of mis-insertion during the connection process, and further avoid the adverse effects such as the inability to transmit data, damage to the circuit inside the instrument, and increase in maintenance costs caused by mis-insertion.

The socket body 11 is detachably connected or fixedly connected to the socket shell 12, wherein: the fixed connection includes a hot melt connection and a welding connection, and the detachable connection includes a threaded connection, a snap connection and a hinge connection. The detachable connection has a simple structure and is easy to install. It can realize the connection and installation between the socket shell 12 and the socket body 11, and it is beautiful, practical and very safe. The fixed connection is an irreversible connection method with a firm connection, a long service life, simple operation, no quality problems during use, and no frequent maintenance.

[0025] In this embodiment, the socket body 11 and the socket shell 12 are both cylindrical components made of hard plastic. The positions of the 43rd and 44th anti-misinsertion sockets are changed in the outermost 12 sockets in the socket body 11, and the positions of the other sockets are the same as the positions of the original connector, so that the 43rd and 44th anti-misinsertion sockets are distributed in a circle with the other outermost sockets. The specific method includes: a regular hexagon composed of the 41st, 42nd, 45th, 46th, 49th and 40th sockets on the original connector, wherein the center lines of the 42nd, 44th and 46th sockets and the 41st, 43rd and 45th sockets form the two sides of the outermost regular hexagon, and a circle is drawn with the socket at the center of the connector socket body 11 as the center and the distance from the center of the 41st or 42nd socket to the center of the circle as the radius, and the 43rd and 44th anti-misinsertion sockets are arranged in a circle. The plug is moved from its original position to the circle along the straight line from the center of the anti-misinsertion plugs No. 43 and 44 to the center of the circle, so that the changed 19-core connector is only symmetrical about one direction. In the existing 19-core connector, because the 19 sockets on the socket body 11 form a regular hexagon, all the sockets are symmetrical in 6 directions. When there is no external limit and the engraving next to the socket is observed, there will be six different ways of plugging when the plug and the socket are directly plugged together, so misinsertion is prone to occur, further avoiding the adverse effects of data transmission failure, damage to the circuit inside the instrument and increased maintenance costs caused by misinsertion problems. In addition, the socket body 11 is detachably connected to the socket shell 12, and the detachable connection structure is simple, beautiful and practical, and easy to install.

In order to prevent the problem of mis-insertion during the connection of the 19-core connector, the pins on the plug body 21 can be set to a position corresponding to the jacks on the socket, the pins and the jacks can be tightly connected, and there is only one connection method to ensure that the 19-core connector can transmit data well. At the same time, the circuit in the 19-core connector will not be damaged due to connection errors. In order to ensure the stability and safety of the plug shell 22 during the connection process, the plug shell 22 can be made of any shape of any heat-resistant and high-hardness ceramic, plastic or other material, as long as its safety and stability as the plug shell 22 are ensured. The plug body 21 can be made of hard plastic material, as long as the stability of the internal connection plug body can be ensured, and there will be no situation where the shell is broken due to excessive or uneven force, thereby extending the service life of the 19-core connector. The plug body 21 is detachably connected or fixedly connected to the plug shell 22, wherein: the fixed connection includes a hot melt connection and a welding connection, and the detachable connection includes a threaded connection, a snap connection and a hinge connection.

[0027] In this embodiment, the plug body 21 and the plug shell 22 are both cylindrical components made of hard plastic. The connecting ends of the plug body 21 and the plug shell 22 are both round.
