Abstract
The utility model provides a temperature sensor. A plug is connected with a socket through threaded connection, and furthermore a sealing ring sleeves a threaded column of the plug, thereby realizing quick detachment and connection between the socket and the plug. Furthermore high connection sealing effect between the socket and the plug is realized, and simultaneously a first cable can be quickly disconnected and connected with a second cable. A first inner hole of the sleeve is provided with a plurality of symmetrically and vertically arranged elongated grooves. The outer peripheral wall of a third cylinder of the plug is fixedly provided with a plurality of vertically arranged elongated projections which are matched with the elongated grooves. Each projection is arranged in a corresponding groove. Problems of contact failure and oil seepage between the first cable and the second cable because of contact failure between the socket and the plug caused by connector rotation because of vibration-caused loosening between a sleeve and a sleeve cap are settled. Furthermore, the first cable is placed in the sleeve, thereby preventing problems of first cable damage and oil seepage caused by collision between the first cable and a metal member outside the sleeve.
