The utility model belongs to the field of
data transmission devices, and discloses a multi-hardware data collection connecting device, which comprises a socket, an inner side of the socket is provided with a plug cavity, and a pin is arranged in the plug cavity; the plug is matched with the
insertion cavity, a jack is formed in the plug, a
lantern ring is installed in the jack, the pin is inserted in the
lantern ring, and a stepped groove is coaxially formed in the end, close to the socket, of the jack; the pressing cylinder is matched with the stepped groove, the pressing cylinder is fixed in the
insertion cavity and coaxially arranged outside the
insertion pin in a sleeving mode, an abutting cavity is formed in the inner side of the pressing cylinder and comprises a circular transition section and a conical abutting section, the transition section is located at the end, close to the socket, of the pressing cylinder, and the inner
diameter of the transition section is larger than the outer
diameter of the
lantern ring; the inner
diameter of the side, away from the lantern ring, of the abutting section is smaller than the outer diameter of the lantern ring, and the lantern ring penetrates through the transition section and abuts against the abutting section. When the pressing cylinder is inserted, the lantern ring is pressed, so that the lantern ring can be stably pressed on the contact pin, and the communication state is stably kept.
