A charging gun includes a housing provided with a receiving cavity, a latching member movably assembled at a periphery of the housing, a circuit module mounted in the receiving cavity, and a waterproof and air-permeable assembly. The circuit module includes a magnetic switch. A mounting recess into which the latching member is mounted is provided at the periphery of the housing, and the latching member is rotatable about a rotation shaft in the mounting recess. The latching member is provided with a magnetic element, a state of the magnetic switch is controlled by a change of a relative distance between the magnetic element and the magnetic switch with rotation of the latching member. A mounting hole communicating with the receiving cavity is provided in a bottom surface of the mounting recess. The waterproof and air-permeable assembly is mounted in the mounting hole to discharge heat in the receiving cavity.

A mining elevator traction cable connecting apparatus and a measuring method therefor, for use in a mining elevator serving a deep-mine. The apparatus includes an industrial personal computer (IPC), a signal collector connected to the IPC, multiple symmetrically arranged cable rings for use in connecting to one end of a traction cable, and a traction cable tension adjusting apparatus connected to the multiple of cable rings. Arranged within the traction cable tension adjusting apparatus are a plurality of hydraulic cylinders, and a plurality of draw wire displacement sensors for use in monitoring the relative displacement between each hydraulic cylinder plunger and a corresponding hydraulic cylinder body. The draw wire displacement sensors and an oil pressure sensor connected to a hydraulic pipeline are connected to the IPC via the signal collector, forming a traction cable tension and degree of adjustment measuring system.
